The following describes the application method of the device by taking the embodiment as an example:
in the initial state, the placing plate 103 is positioned at a high position under the action of the return spring 104, at the moment, the inserted rod 504 is far away from the wheel 106, and the whole device has no load and can be freely pushed;
the multimedia recording and playing equipment is placed into the placing cylinder 102, the placing cylinder 102 protects the multimedia recording and playing equipment, and the whole device can be pushed to carry the multimedia recording and playing equipment to move.
Meanwhile, the placing plate 103 moves downwards due to the increase of the load, and the rack 202 is driven to synchronously descend by the slide rod 201; the rack 202 drives the driven gear 203 to drive the first shaft 204 to rotate; the first friction wheel 206 at the left end of the first shaft 204 rotates immediately, and drives the second friction wheel 302 to drive the second shaft 301 and the third shaft 303 to rotate; the first gear 304 on the third shaft 303 drives the second gear 401 to drive the fourth shaft 402 to rotate; the fourth shaft 402 enables the fifth shaft 405 to rotate through the matching of the first bevel gear 403 and the second bevel gear 404, so that the worm 405 on the fifth shaft 405 rotates and drives the worm wheel 501 to deflect; and with the deflection of the worm wheel 501, the rotating rod 502 pushes the inserting rod 503 to extend to the wheel 106;
if the weight of the placing plate 103 exceeds a certain amount, the inserting rod 503 will abut against the wheel 106 and be inserted into the inserting hole 106 to realize locking, so that the wheel 106 cannot rotate; even if the inserting rod 503 is not inserted into the inserting hole 106, the whole device is pushed to move, the wheel 106 rotates, the inserting rod 503 is inserted into the inserting hole 106, and the wheel 106 stops rotating; thus, the whole device is difficult to push, and can effectively remind the user that the load of the placing plate 103 exceeds the threshold value, and the load is reduced.
In this embodiment, the top end of the third shaft 303 is fixedly connected to the bottom end of the second shaft 301.
Example 3
On the basis of the above-described embodiments,
also comprises a clamping component 7; the clamping assembly 7 is arranged on the right side wall of the placing cylinder 102 and comprises a side pressure plate 701, a guide rod 702, a moving screw 703 and a second hand wheel 704;

Specifically, the second hand wheel 704 rotates the moving screw rod 703, and based on the thread effect, the moving screw rod 703 displaces relative to the right side wall of the placing cylinder 102 and drives the side pressure plate 701 to move under the guidance of the guide rod 702, so that the multimedia recording and playing equipment is clamped and fixed, and the multimedia recording and playing equipment is prevented from moving on the placing plate 103.
In order to enhance the fixation of the position of the multimedia recording and playing device, rubber bulges 705 are processed on the left side surface of the side pressure plate 701 and the left inner wall of the placing cylinder 102, so that the contact friction is increased.
Example 4
The difference from the above embodiment is that the present embodiment can eliminate the load threshold limitation of the placing plate 103.

Specifically, during normal use, the handle 307 locks the mounting frame 205, positions the second shaft 301, and keeps the first friction wheel 206 and the second friction wheel 302 engaged, so that the first friction wheel 302 can drive the second friction wheel 302 to rotate with the second shaft 301, and further drive the third shaft 303 to rotate through the spline shaft 308.
If the load threshold limit of the placing plate 103 needs to be removed, the first friction wheel 206 and the second friction wheel 302 are disengaged by pulling up the second shaft 301 through the handle 307, the second shaft 301 does not rotate by itself under the influence of the load of the placing plate 103, and the inserting and placing assembly 5 cannot work automatically;
the present usage is recommended only for emergency treatment. In this case, of course, the second shaft 301 can still be rotated by the handle 307, and the spline shaft 308 is still inserted into the second shaft 301, so that the third shaft 303 is rotated, and the insertion assembly 5 works to lock the wheel 106.
