The invention discloses a training hurdle bracket easy to ascend and descend. The training hurdle bracket comprises bases, hurdle columns and a hurdle plate. The hurdle columns are vertically arranged on two sides of the bases, the hurdle plate is arranged on the tops of the two hurdle columns and is connected with the two hurdle columns, a seat with an opening is arranged in each base, a swing rod which upwardly extends out of the corresponding opening and can drive the corresponding hurdle column to swing towards the direction of a track when an athlete kicks the hurdle plate is arranged inside each seat, the tops of the swing rods are connected with the hurdle columns, and the bottoms of the swing rods are elastically connected with the seats in a swing manner. The training hurdle bracket has the advantages that the seats are matched with the swing rods, and trouble caused by the fact that an existing hurdle plate needs to be manually lifted up when kicked down can be prevented owing to mutual effects of reset supporting springs on two sides of the swing rods; the swing rods are arranged in the bases, so that the training hurdle bracket is compact in structure and long in service life; the training hurdle bracket is simple in structure, low in cost and suitable for popularization and application.

A display apparatus generates a high visibility optical signal, such as an ICON, the ICON comprising a symbol, shape, or other image-like representation. The ICON becomes visible at an observation point during an illumination ON-state. The ICON may be formed as a portion of display medium, for example as a machined portion of a mirror capable of forming images of a scene by reflection in normal operation. The visibility of the ICON in the illumination OFF-state from an observation point is sufficiently low such that the normal operation of the display medium is maintained. The display apparatus may be used in a blind spot warning system for a vehicle. Visible wavelength LEDs, RGB LEDs and / or diode lasers may be utilized as an illumination source. Ultrashort laser processing or other methods for material modification may be utilized to form microscopic features which distribute incident light, increasing the visibility of the optical signal at an observation point in an ON-state, with very low visibility in the OFF-state and minimal effect on the image in the display medium in the OFF state.

The invention belongs to the technical field of feed, and in particular relates to cattle feed capable of improving meat quality, and a preparation method thereof. The cattle feed is prepared from Italian ryegrass, soybean straws, calcium bicarbonate, traditional Chinese medicine additives, trace element mixing materials, vitamin mixing materials and a condiment. The feed has the characteristics of high palatability, high nutrient content and easiness in absorption, and can improve the beef quality and improve the immunity of cattle.

The invention discloses a battery box facilitating storage in the field of lithium battery equipment. The battery box comprises a box body, wherein the box body comprises a top plate, a bottom plate and a door body; the battery box further comprises a push frame, the push frame comprises a storage table, wing plates are vertically connected with the lower surface of the storage table, yield grooves penetrating through the bottom plate are formed in the wing plates, a locking groove for locking the door body is formed in one end, away from openings of the yield grooves, of the storage table, an opening of the locking groove is upward, and outside threaded holes are formed in the locking groove; notches are formed in the bottom plate and used for allowing groove root parts of the yield grooves to pass; tongue-and-grooves are formed in the top plate, tenon strips vertically penetrating through the tongue-and-grooves are arranged on the inner side of the door body, and inside threaded holes corresponding to the outside threaded holes are formed in the door body. When the battery box is used for accommodating batteries, the storage table is pulled out of the box body by pulling the push frame, the batteries are placed without obstacles, and then the storage table is pushed into the box body and the door body is locked; with the adoption of the scheme of the battery box facilitating storage, the batteries are conveniently placed, and the problem that the batteries in a conventional battery box are inconvenient to take is solved.

The invention relates to the field of test experiments of automobile engines, in particular to a manufacturing technology of a carbon fiber loading rod for automobile engine testing and the carbon fiber loading rod. According to the manufacturing technology of the carbon fiber loading rod, multiple layers of prepreg are laid and distributed on a die, during each time of laying and distributing, different laying and distributing starting lines are selected to serve as starting ends, in the laying and distributing process, pre-compaction is carried out multiple times, and curing, die releasing, side cutting, grinding and assembling steps are carried out. Meanwhile, the invention discloses the carbon fiber loading rod. During each time of laying and distributing, the different laying and distributing starting lines are selected to serve as the starting ends, in the laying and distributing process, pre-compaction is carried out multiple times, gaps between layers of the prepreg of a carbon fiber can be effectively reduced, the whole strength of the carbon fiber loading rod can be effectively improved, bending or cracking phenomena appearing in the use process of the rod can be avoided, normal use performance of the carbon fiber loading rod is ensured, and unnecessary economic losses and personal injuries are avoided.

The invention discloses an extrusion mold using a reflux thimble and a cooling elastic plate to quickly cool a plastic profile. The extrusion mold structurally comprises a clamping plate, an upper guiding column hole, a mold core plate, a lower guiding column and an elastic plate device; a condensing tube surrounds the cooling elastic plate by one circle, meanwhile, by adopting a spiral surrounding mode, the condensing tube is cooled, thus the large temperature difference is formed between the condensing tube and a formed high-temperature plastic product, the mutual bonding probability is decreased, and the condensing tube and the formed high-temperature plastic product are easier to separate accordingly; meanwhile, the heat expansion phenomenon of the cooling elastic plate is avoided, pop-up delay of the cooling elastic plate due to friction is avoided, and thus the action of the cooling elastic plate is played normally; the air output sequence of the thimble and an air jacking tube is controlled, air blowing continuity is improved, the mode of air blowing is increased, and thus the plastic product falls off more easily; an air valve conducts air blowing and pressurizing through an air cavity tube, and thus the thimble overcomes an annular spring to be popped up; and meanwhile, the air jacking tube is in a communicating state through a sliding control plate, air starts to be blown between the plastic product and a mold core, on the basis of physical pushing of the elastic plate, the air blowing effect is improved, and the demolding efficiency is improved.

A stuffed toy with removable arms, legs, and other parts uses magnets to allow easy attachment and removal. A magnet (10) interlocks with another piece (20)o prevent lateral movement or slippage of the magnets against the piece. Variously colored stuffed toys can be arranged together so that the user can mix and match variously shaped and colored pieces with variously shaped and colored main bodies. The stuffed toys can mimic actual limb rotation and positioning because the magnets permit stuffed toy pieces to rotate relative to one another once the pieces are attached via magnets.
