As one mode of the present invention, the anti-skid panel 201 is provided with a plurality of semicircular grooves 20101 which are linearly distributed, the inner wall of the bottom of the semicircular grooves 20101 is provided with a plurality of vent holes 20102 which are linearly arranged, when the roller on the cart contacts the anti-skid panel 201, the plurality of semicircular grooves 20101 on the anti-skid panel 201 can increase the contact area between the roller and the anti-skid panel 201, so that the roller cannot easily roll on the anti-skid panel 201, so that the cart can be more stable on the anti-skid panel 201, and the plurality of vent holes 20102 on the semicircular grooves 20101 can make the peculiar smell above the anti-skid panel 201 pass through the anti-skid panel 201 and be discharged.

As a mode of the invention, two connection posts 20207 are fixedly installed at the bottom of the second rectangular bar 20202, bottom ends of the two connection posts 20207 are fixedly connected with an inner wall of the bottom of the rectangular groove 20103, two round bars 20203 are fixedly installed at the bottom of the first rectangular bar 20201, the two round bars 20203 both penetrate through the second rectangular bar 20202 and are slidably connected with the second rectangular bar 20202, a limit plate is fixedly installed at bottom ends of the two round bars 20203, a third spring 20204 is slidably sleeved on each of the two round bars 20203, top ends and bottom ends of the two third springs 20204 are respectively fixedly connected with the first rectangular bar 20201 and the second rectangular bar 20202, when a roller on the dolly is contacted with the taper pin mechanism 202, the roller can drive the first rectangular bar 20201 and the second rectangular bar 20202 to approach each other, a plurality of anti-skid pins 20206 respectively pass through corresponding through holes 20205, and the anti-skid pins 20206 are mutually contacted with the roller, thereby can be more firm when can making the gyro wheel be in skid-proof panel 201 top, the condition that can not appear rocking easily for can be very firm, comparatively safe when small handcart and plywood contact.

The working principle is that when the trolley moves to the upper part of the plywood, the antiskid mechanism 2 is driven by the gravity of the trolley to move downwards, the antiskid panel 201 can drive the driving mechanism 306 to approach towards the antiskid panel 201 in the process, the driving mechanism 306 drives the 307 screw rod to move upwards and downwards, in the process, the disc 30603 is close to the first annular block 30601, the disc 30603 drives the screw rod 307 to move upwards in the upward moving process, the screw rod 307 drives the paddle 305 on the ball screw rod sleeve 304 to rotate, the rotating paddle 305 can suck peculiar smell above the antiskid panel 201 into the rectangular frame 1, then the peculiar smell in the rectangular frame 1 is discharged from the rectangular holes 106 on the periphery, when the roller on the trolley is contacted with the taper pin mechanism 202, the semi-circular grooves 20101 on the antiskid panel 201 can increase the contact area between the roller and the antiskid panel 201, and therefore the roller cannot easily roll on the antiskid panel 201, simultaneously the gyro wheel can drive first rectangle strip 20201 and second rectangle strip 20202 and be close to each other, and a plurality of studs 20206 pass corresponding through-hole 20205 respectively, and stud 20206 will contact each other with the gyro wheel to can make the gyro wheel can be more firm in the time of being in antiskid panel 201 top, the condition of rocking can not appear easily, can very stabilize in the time of making small handcart and plywood contact, it is comparatively safe.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
