Functions: (1) An inner track and a locking component are provided inside the outer track. The bottom wall of the outer track is provided with a sliding opening. The locking component is provided with a screw hole inside and a baffle is provided on the side wall of the locking component. One end of the screw hole faces the top wall of the outer track, and the other end of the screw hole faces the sliding opening. The baffle is inserted into the inner track. Thus, the locking component can be moved to a suitable position along the sliding opening. (2) A screw is installed inside the screw hole. Tighten the screw until it reaches the inner side of the top wall of the outer track, so that the baffle generates a reaction force. The baffle presses down on the inner track to achieve locking between the inner track and the outer track. Thus, the glue-applied assembly method can be eliminated. The locking component with the baffle is tightened with the screw to generate a reaction force, so that the baffle presses the track and the screw is tightened to fix it. From the above analysis, it can be seen that this utility model: 1. It does not need to strictly control the gap tolerance between the tracks. It only needs to ensure that each track is smoothly assembled together and then fixed by the locking component. 2. It can be disassembled twice and reworked to avoid waste. 3. There are no defects after applying the glue, and there is no need to wait for the glue to dry, which greatly improves assembly efficiency.

[0031] Specifically, the outer track 1 is further provided with a middle track 2, and the middle track 2 has two mounting slots 201 distributed vertically inside, with an inner track 3 installed in each of the two mounting slots 201. Under the force of the baffle 402, the inner track 3 presses down to press the middle track 2, and the middle track 2 presses down to press the outer track 1, thereby locking the inner track 3 with the middle track 2 and the outer track 1. Function: The middle track 2 supports the two inner tracks 3 distributed vertically.

[0032] Specifically, there are two intermediate tracks 2, one of which is located at the upper left of the sliding opening 101, and the other is located at the upper right of the sliding opening 101. The two mounting slots 201 of the upper left intermediate track 2 are respectively arranged opposite to the two mounting slots 201 of the upper right intermediate track 2. Function: By setting two intermediate tracks 2, two inner tracks 3 can be set on both the left and right sides inside the outer track 1.

[0033] Specifically, the assembly groove 201 is provided with a rectangular notch 202 near one side of the middle of the outer track 1, and the inner wall of the side of the assembly groove 201 away from the middle of the outer track 1 is provided with a circular channel 203; the inner track 3 comprises a circular track 301 and a rectangular track 302 connected together, the circular track 301 is assembled in the circular channel 203, and the rectangular track 302 is assembled in the rectangular notch 202.

Action: Through the limiting cooperation of the limiting block 204 and the limiting groove 102, the outer track 1 and the middle track 2 can have a limiting function when assembled.

[0035] Specifically, the left and right walls of the locking member 4 are respectively provided with baffles 402, and the baffles 402 on the two sides are respectively inserted into the rectangular tracks 302 on the two sides; the baffles 402 press the bottom wall of the rectangular track 302 downward, the bottom wall of the rectangular track 302 presses the bottom wall of the rectangular notch 202 downward, and the bottom wall of the rectangular notch 202 presses the bottom wall of the outer track 1 downward. Action: By tightening the screws with the locking member 4, a counterforce is generated to press the tracks with the baffles on both sides; at the same time, the locking member 4 can be moved to a suitable position for tightening and fixing. That is, the tracks are assembled by tightening the screws and cooperating with the locking member 4, and can be freely moved to select a suitable position for tightening and fixing.

[0036] Specifically, the number of locking members 4 includes two, one of which has a baffle 402 inserted into the inside of the upper inner track 3, and the other has a baffle 402 inserted into the inside of the lower inner track 3. Action: Since the two inner tracks 3 are distributed upward and downward, a total of 2 locking members 4 need to be tightened, and they are in opposite directions, ensuring that both layers inside the track are pressed tightly. Note that the main part that is pressed tightly is the inner track, as shown in Figure 1 , 2 .

[0037] Specifically, the two locking members 4 are respectively located at the front and rear ends of the outer track 1. Action: The front and rear ends of the outer track 1 are provided with locking members 4, so that the inner track 3 is uniformly stressed. Of course, according to actual needs, the number of locking members 4 can also be four or six, and the position can also be freely adjusted, which will not be limited here.

Action: The one end or both ends being open can facilitate the installation of the locking member 4 and the subsequent work of the track.

[0039] Specifically, the outer track 1 is rectangular, and the locking piece 4 is columnar. Action: the simple structure design of the locking piece 4 facilitates the free movement and adjustment of the locking piece 4.

[0040] In summary, the working principle of the present scheme is as follows: the screw is tightened through the screw hole of the locking piece 4 until it reaches the inner side of the outer track, and then the locking piece 4 generates a counterforce to compress the track; in total, 2 locking pieces 4 need to be tightened in opposite directions to ensure that both layers inside the track are compressed, and it is mainly the inner track that is compressed, as shown in Figure 1 、 2 .

[0041] The present scheme can produce the following positive effects:

[0042] Convenient production and assembly, greatly improving production efficiency.

[0043] Reduces the adverse effects caused by glue assembly, and reduces the overall defect rate.
