The invention belongs to the field of warehousing logistics, and particularly relates to a logistics warehouse with a conveying function. For the problems that an existing transfer trolley is poor inlimiting effect, objects are likely to fall, stability of the transfer trolley during parking is poor, meanwhile, the transfer trolley does not have the damping performance, and object damage is likely to be caused, the following scheme is provided at present, the logistics warehouse comprises a base, the top of the base is fixedly connected with a containing box, a door hole is formed in the front side of the containing box, four sliding grooves are formed in the front side of the containing box and internally provided with sliding plates in a sliding manner, the same door panel is fixedly connected to the front sides of every two corresponding sliding plates, the two door panels are in contact and are in seal contact with the door hole, and two fixing plates are fixedly connected to thefront side of the containing box. The logistics warehouse has a good limiting effect and can well conduct limiting protection on the objects, buffering protection can be conducted on the objects, meanwhile, the door panels are conveniently opened and closed, and stability is improved through rubber anti-skid pads.

The invention provides intelligent control metal cutting equipment. According to the technical scheme, the equipment is composed of a base, multiple supporting plates, two cutting displacement tracks,a cutting displacement device, two traction fixing frames, two traction boxes, a cutting bearing and moving device, a cutting operation cabin, a signal receiver, a control box and a pressing cuttingdevice. The cutting bearing and moving device is composed of a horizontal displacement fixing table, four pulleys, two horizontal displacement drive motors, a horizontal displacement transmission chain and a cutting bearing table. The pressing cutting device is composed of a cutting pressing plate, four lifting shafts, two cutting transmission shafts and multiple cutting transmission belts. Each cutting transmission belt is provided with a cutting head base, a cutting head lifting valve and a cutting head. According to the equipment, precise measurement and fine adjustment can be carried out according to the set position, the requirement of a set value is met, the equipment is suitable for carrying out cutting machining on various metal plates, and then the working efficiency and the product precision of the intelligent control metal cutting equipment are improved.

The invention relates to the technical field of switch cabinet installation, in particular to stable alignment installation equipment for 10 kv switch cabinet installation, which comprises a power distribution cabinet, a fixing mechanism, a clamping mechanism, a limiting mechanism, an abutting mechanism and a rolling mechanism, under the action of the fixing mechanism, the power distribution cabinets of different sizes can be conveniently sleeved and abutted, under the action of the limiting mechanism, the fixing mechanism can be conveniently adjusted and then subjected to limiting protection, under the action of the clamping mechanism, the bottom of the power distribution cabinet can be conveniently clamped and hung, and clamping is fastened through adjustment; and through cooperation of the fixing mechanism, workers can lift, carry and install the power distribution cabinet easily and conveniently, the clamping mechanism can abut against and clamp the bottom of the power distribution cabinet tightly and firmly under the action of the abutting mechanism, follow-up carrying separation is prevented, the clamping mechanism can roll conveniently under the action of the rolling mechanism, the power distribution cabinet can be moved on the ground conveniently, and physical output of workers during carrying is reduced.

The invention discloses an integrated device for processing a solar cell backboard film. The integrated device comprises a device base and a supporting frame; the supporting frame is located right above the device base; supporting legs are installed at the corners of the bottom end of the device base; a roller is installed on one side of each supporting leg; a transmission mechanism is installed on the upper end surface of the supporting frame; one side of the transmission mechanism is provided with a conveying mechanism; the other side of the transmission mechanism is provided with a processing mechanism; and a conveying table is installed between the conveying mechanism and the processing mechanism. The integrated device for processing the solar cell backboard film can be used for automatically conveying and processing the to-be-processed cell backboard film and conveying the processed cell backboard film, so that the manpower is effectively liberated, the mechanical automatic processing production is realized, the working efficiency is greatly improved, the production cost is effectively reduced, and the product quality can be ensured; and the whole device is convenient to moveand high in practicability.

The invention discloses a novel fitness strolling machine. The strolling machine comprises a base, a first supporting frame is installed at the upper end of the base, a second supporting frame is installed on the part, corresponding to the first supporting frame, of the upper end of the base, and a first fixing seat is fixedly arranged on one side of the first supporting frame. Calves of a user can be conveniently conducted when the user exercises through a massage device, the blood circulation of the calves of the user is conveniently promoted to enhance the toughness of legs and relieve thefatigue of muscles, pedal supporting rods on the rolling machine is conveniently limited through limiting rods to prevent the influence on the user by larger swing arch of pedals, the swing amplitudeof the supporting rod can be relieved by using buffering plates and springs to prevent counter force from generating on the user due to excessive swing amplitude, limiting protection can be conveniently conducted through limiting rings when elderly people or children exercise, and therefore the problem that elderly people and children fall when exercise is avoided.
