The invention provides a sound system for vehicles. The sound system is used for recording, playing and / or displaying recorded information, and comprises a touch display screen with multiple touch keys; the multiple touch keys include a recording key and an information storage key; the recording key is used for recording voice information by responding to the click operation of a user; the information storage key is used for storing at least one voice information according to a time sequence; the information storage key is operable; therefore, after the user performs the click operation, the voice information is played; and / or, the voice information is converted into character information to display; the sound system further comprises an additional mechanical recording button for recording the voice information by responding to the user operation; and, when any one of the recording key and the mechanical recording button is operated, recording of the voice information can be started. By means of the sound system provided by the invention, information is conveniently recorded in a driving process; furthermore, the information integrity can be repeated after a driver gets off; and in addition, the sound system is timely and rapid when a great and important event needs to be recorded.

The invention discloses a pair of front-and-rear-rod-shaped foot swing type roller skates. Each roller skate comprises a round steel embedded part, a front-and-rear-rod-shaped panel, wear-proof bottom strips, lower bearings, upper bearings, wheel forks provided with shafts, upper round covers and PU (polyurethane) wheels, wherein the round steel embedded part is injected into the front-and-rear-rod-shaped panel; the front-and-rear-rod-shaped panel is rod-shaped at the front part, match-head-shaped at the front end, elliptical and cylindrical at the rear part, cylindrical at the rear end and disk-shaped in the middle; a counter bore is formed in each of the upper and lower sides of the front end and the rear end of the front-and-rear-rod-shaped panel; the upper and lower counter bores are connected with through holes; the upper counter bores of the front-and-rear-rod-shaped panel are connected with shallow counter bores; two elliptic holes are formed in the disk-shaped bottom surface of the front-and-rear-rod-shaped panel; the bottom surfaces on two sides in the middle of the front-and-rear-rod-shaped panel are connected with the wear-proof bottom strips; the upper and lower bearings are embedded into the upper and lower counter bores; the shafts of the wheel forks provided with the shafts are connected with the upper and lower bearings; the wheel forks provided with the shafts are connected with the PU wheels; the upper round covers are connected to the tops of the shafts of the wheel forks provided with the shafts and positioned in the shallow counter bores. Two front-and-rear-rod-shaped foot swing type roller skates are matched in a front-rear manner and paired for use.

Provided is a large-wheel-diameter swinging and twisting type sliding plate. The large-wheel-diameter swinging and twisting type sliding plate comprises a front frame, a rear frame, pedal connecting pieces, pedals, anti-abrasion bottom rods, wheel-fork bearings, a swinging and twisting mechanism, wheel forks with shafts, PU wheels and insert circular caps. The front frame is formed by welding a front arc tube, a front beam tube and a rotating drum, the rear frame is formed by welding a rear arc tube, a rear beam tube and a rotating drum, the pedal connecting pieces are welded to the front beam tube and the rear beam tube respectively, the pedals are connected with the pedal connecting pieces, the anti-abrasion bottom rods are connected with the front frame and the rear frame respectively, the wheel-fork bearings are inlaid in the upper end and the lower end of the rotating drum respectively, the swinging and twisting mechanism is composed of spring steel, a polyurethane locating sleeve and a plastic lining piece and connected to the rear end of the front beam tube and the front end of the rear beam tube, each wheel fork with the shaft is formed by welding a metal wheel fork and a screw cylinder of a counterlocked bolt, the PU wheels are connected with the wheel forks with the shafts respectively, the wheel forks with the shafts are connected with the wheel fork bearings, and a flat bolt of each insert circular cap is connected in the screw cylinder of the corresponding counterlocked bolt in a screwed mode.

The invention relates to the technical field of sports balls, and discloses a method for preparing balls imitating manual machine sewing, comprising the following steps: making a composite material; punching the composite material into a sheet-shaped monomer; adjusting the tension of the bottom thread in a sewing machine It is 3-6kgf, and the sheet-shaped monomers are sewed together to make a ball skin; the ball skin is covered on the bladder to make a sphere; the sphere is put into a mold of a corresponding size, heated and controlled to carry out hot pressing and shaping, the present invention It also discloses that the above-mentioned preparation method imitates hand-sewn balls. The imitated hand-sewn balls prepared by the present invention not only have good appearance and visual appearance, but also have similar appearance effects to hand-sewn balls, and the strong enemy of sewing is also close to hand-sewn balls.

The invention discloses a fire-retardant polyolefin based wood plastic composite material and a preparation method thereof, and relates to a wood plastic composite material and a preparation method thereof, and the composite material and method provided by the invention can be used for solving problems that the existing fire-retardant wood plastic composite material has high heat release efficiency in burning and high smoke production, and can generate CO harmful gas easily. The flame-retardant polyolefin based wood plastic composite material is prepared from wood fiber materials, plastics, acoupling agent, a lubricant, an antioxidant, a nano inorganic fire retardant and a mineral filler. The method comprises the following steps: putting the wood fiber materials, the coupling agent and the lubricant into a high-speed mixing machine for hot mixing; then putting into a cold mixing machine for cold mixing, sending the plastics, the antioxidant, the nano inorganic fire retardant and the mineral filler into the cold mixing machine and then mixing; and then carrying out fusing and extruding for granulation by adopting extruding, injection, hot compressing or mold compression for molding, thus the fire-retardant polyolefin based wood plastic composite material is obtained. The wood plastic composite material provided by the invention has low heat release rate in burning and less smoke production, and is healthy and environmentally-friendly, and can be widely applied to the fields of indoor construction, decoration and furnishing materials and the like.
