[0035] The following is combined with Figure 1 -Attached Fig. 9 The present invention is described in further detail.

[0036] The present invention discloses a guide groove cover. Figure 1-Figure 9 , including a launching platform 1, a control mechanism 2 is arranged on the launching platform 1, the control mechanism 2 includes two track plates 21, the two track plates 21 are arranged inside the launching platform 1, two cover plates 22 are arranged between the two track plates 21, and transport chains 23 are fixedly installed on both the front and rear sides of the cover plates 22, and the transport chains 23 are arranged inside the track plates 21 and are slidably connected to the track plates 21;

[0037] Two mounting plates 24 are fixedly connected to the front side wall of the inner cavity of the launch platform 1, and the inner sides of the two mounting plates 24 are fixedly connected to the first motor 25. Two connecting rods 26 are rotatably connected inside the launch platform 1, and one end of the connecting rod 26 is rotatably connected to the mounting plate 24. The first motor 25 is fixedly connected to one end of the connecting rod 26 through the output shaft, and a sprocket 27 is fixedly connected to the outside of the connecting rod 26. A through groove is provided on the track plate 21, and the sprocket 27 passes through the through groove. The sprocket 27 is meshed with the transport chain 23, and one end of one of the cover plates 22 is fixedly connected to the first contact plate 28, and one end of the other cover plate 22 is fixedly connected to the second contact plate 29, and the first contact plate 28 is fitted with the second contact plate 29;

[0038] A cable mechanism 3 is also provided inside the launch platform 1. Rectangular plates 298 are fixedly connected on both sides of the track plate 21. The rectangular plates 298 are fixedly connected to the inside of the launch platform 1. The cover plate 22 can be rolled up and bent. Therefore, during use, after the first motor 25 works, the sprocket 27 is prompted to rotate and drive the transport chain 23 to move. After the transport chain 23 moves, it further drives the cover plate 22 to move inside the track plate 21. The corresponding side can realize that the two cover plates 22 are stretched out and spliced ​​into a complete platform for the user to stand on it and operate. Similarly, controlling the sprocket 27 to rotate in the opposite direction to the above can prompt the cover plate 22 to be rolled up in the track plate 21, and the two cover plates 22 are separated. Compared with the integrated and non-bendable cover plate 22, it has the characteristics of small space occupation and greater flexibility.

[0039] The control mechanism 2 includes a positioning assembly, which includes a first connection seat 291, a second connection seat 292, two first plug-in boards 293 and two second plug-in boards 294. The first connection seat 291 is arranged between the two first plug-in boards 293, and the second connection seat 292 is arranged between the two second plug-in boards 294. The first plug-in board 293 and the first connection seat 291 are both fixedly connected to the top of the first contact plate 28, and the second plug-in board 294 and the second connection seat 292 are both fixedly connected to the top of the second contact plate 29. The first connection seat 291 is spliced ​​with the second connection seat 292, and the first plug-in board 293 and the second plug-in board 294 are spliced;

[0040] The first plug-in board 293 extends into the inner side of the second plug-in board 294 and contacts the inner surface of the second plug-in board 294. A latch rod 295 is provided on the top of the second plug-in board 294. The latch rod 295 passes through the top walls of the first plug-in board 293 and the second plug-in board 294 respectively. After the latch rod 295 is inserted, the first plug-in board 293 and the second plug-in board 294 are inseparable. The inner side of the first connecting seat 291 is fixedly connected to the limiting rod 296. The inner side of the second connecting seat 292 is connected to a card plate 297 through a rotating shaft. The card plate 297 extends into the inner side of the first connecting seat 291. The outer side of the limiting rod 296 contacts the inner surface of the card plate 297. When the card plate 297 is flipped until the limiting rod 296 is on its inner side, the first connecting seat 291 and the second connecting seat 292 are in a locked state.

[0041] The cable mechanism 3 includes two movable plates 31, both movable plates 31 are slidably connected to the inside of the launch platform 1, one side of the first contact plate 28 and the second contact plate 29 are fixedly connected with a failure cable 32, one end of the failure cable 32 is fixedly connected to the top of the movable plate 31, and the inside of the launch platform 1 is respectively fixedly connected with a U-shaped plate 33 and an L-shaped plate 34, one side of the L-shaped plate 34 is rotatably connected with a bidirectional threaded rod 35, one end of the bidirectional threaded rod 35 is rotatably connected to the inside of the launch platform 1, and the threads on both sides of the bidirectional threaded rod 35 are in opposite directions;

[0042] A second motor 36 is fixedly connected to the inner side of the L-shaped plate 34, and the second motor 36 is fixedly connected to one end of a bidirectional threaded rod 35 through an output shaft. The bidirectional threaded rod 35 passes through the two movable plates 31 in sequence, and the bidirectional threaded rod 35 is respectively connected to the two movable plates 31 through threads. After the bidirectional threaded rod 35 rotates, it drives the two movable plates 31 to move towards or away from each other. A guide wheel 37 is connected to the inner side of the U-shaped plate 33 through a rotating shaft. The guide wheel 37 is in contact with the failed cable 32, and the guide wheel 37 guides the failed cable 32.

[0043] In the actual operation process, firstly, the device is connected to the power supply. The cover plate 22 is a structure that can be rolled and bent. After the first motor 25 works, it drives the connecting rod 26 to rotate, and the connecting rod 26 drives the sprocket 27 to rotate. The sprocket 27 drives the transport chain 23 to move. The transport chain 23 can move in the track plate 21 and roll up along the inner groove of the track plate 21. At this time, the transport chain 23 drives the cover plate 22 to move, roll up or stretch. When both cover plates 22 perform the stretching operation and promote the first contact plate 28 and the second contact plate 29 to fit together, the two cover plates 22 are spliced ​​into a complete work surface. Similarly, if both cover plates 22 perform the rolling operation, the first contact plate 28 and the second contact plate 29 tend to move away from each other, so as to separate them. The rolling or stretching method is controlled in this way. Compared with the traditional integrated cover plate 22, it occupies a smaller volume and is more flexible to use.

[0044] Finally, when the first contact plate 28 and the second contact plate 29 are fitted together, the first plug plate 293 is inserted into the second plug plate 294. After the latch rod 295 is inserted from the top downward, the first plug plate 293 and the second plug plate 294 cannot be separated. The top wall of the first connecting seat 291 is lower than the top wall of the second connecting seat 292. Therefore, at this time, the top wall of the first connecting seat 291 is below the top wall of the second connecting seat 292. Then, the card plate 297 is flipped to make the limit rod 296 be in the groove position on the inner side of the card plate 297, so that the locking purpose of the first connecting seat 291 and the second connecting seat 292 can be achieved. Through the above operation, the stability of the first contact plate 28 and the second contact plate 29 in the fitted state can be further improved, and the safety is higher.

[0045] While the first motor 25 is working, the second motor 36 works synchronously, and the second motor 36 drives the bidirectional threaded rod 35 to rotate, and the bidirectional threaded rod 35 drives the two movable plates 31 to move toward or away from each other. After the movable plate 31 moves, the failure cable 32 is pulled. In an unexpected situation, if the first motor 25 works abnormally, the failure cable 32 can still be controlled to pull the first contact plate 28 and the second contact plate 29 by controlling the movement of the movable plate 31, so as to achieve the separation of the first contact plate 28 and the second contact plate 29, which effectively improves the stability and safety of the device when used.
