A resistance member 205 cooperating with the movable member 204 is arranged on the insert member 202, and also includes an unlocking component 300. The unlocking component 300 includes an auxiliary member 301 arranged on the support member 201, and a positioning member 302 is arranged in the auxiliary member 301. The positioning member 302 and the rotating member 203 cooperate to unlock the device.

[0031] In the prior art, cables are piled up and crowded in the cable trench. At the same time, in the process of returning the old cables, they may be dragged into the operating screen cabinet. The present invention further improves the bracket during use. By laying cables at multiple levels, a lot of manpower can be saved when the cables need to be returned during the later transformation process. At the same time, the stability of the cables is guaranteed. The device further refines the bracket structure. A connecting structure 200 is provided between the first base plate 100 and the second base plate 101. The first base plate 100 and the second base plate 101 are quickly positioned through the cooperation of the support member 201 and the plug-in member 202. At the same time, the device is locked through the movable member 204 and the resistance member 205. In addition, the unlocking component 300 is provided. By pressing the auxiliary member 301, the auxiliary member 301 drives the positioning member 302 to work together. At this time, the positioning member 302 and the rotating member 203 cooperate to unlock the device.

[0032] Specifically, the support member 201 includes a sleeve 201a fixedly connected to the upper end surface of the first base plate 100, a mounting groove 201b is provided in the sleeve 201a, and the insert member 202 is correspondingly abutted against the mounting groove 201b.

[0033] Depend on Figures 2 to 5 It can be seen that a hollow sleeve 201a is fixedly connected to the upper end surface of the first base plate 100, and a connecting seat 202a is correspondingly fixed to the lower end surface of the second base plate 101, and a chuck 202b and an insertion rod 202c are fixed on the connecting seat 202a, and the chuck 202b and the insertion rod 202c are pressed against the sleeve 201a to achieve the fixation between the first base plate 100 and the second base plate 101. For the stability of the connection, the number of sleeves 201a needs to be greater than 3, and they are distributed in a square shape around the end of the first base plate 100. At the same time, the number of connecting seats 202a needs to be equal to the number of sleeves 201a, and the positions correspond one to one to ensure the connection strength and stability of the first base plate 100 and the second base plate 101. In the prior art, the first base plate 100 and the second base plate 101 can be connected in a variety of ways, such as snap-on and bolt connections.

[0034] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a rotating member 203 of the secondary cable bracket in the protection room. The rotating member 203 includes a movable disk 203a arranged in the installation groove 201b, and an opening 203b is arranged in the middle of the movable disk 203a. The insertion rod 202c is correspondingly inserted in the opening 203b. The two sides of the upper end surface of the movable disk 203a are recessed inward to form a low-position portion 203c. The two sides of the low-position portion 203c extend from bottom to top to form an inclined portion 203d. A high-position portion 203e is arranged between the inclined portions 203d on both sides. An annular plate 203f is arranged at the position of the upper end surface of the first bottom plate 100 corresponding to the sleeve 201a, and a connecting block 203g is arranged inside the annular plate 203f. The connecting block 203g passes through the arc-shaped opening 201c and is arranged on the outer wall of the movable disk 203a.

[0035] Depend on Figures 4 to 8It can be known that the movable disk 203a is rotatably connected in the mounting groove 201b through the bearing, the interior of the movable disk 203a is hollow, and the insert rod 202c is correspondingly inserted into the movable disk 203a. At the same time, the present invention further defines the structure of the movable disk 203a, and the upper end face of the movable disk 203a is composed of three end faces, namely the high portion 203e, the low portion 203c and the inclined portion 203d. Through the arrangement of the high portion 203e, the low portion 203c and the inclined portion 203d, the movable part 204 is moved in the vertical direction under the pressure of the end face, and the movable disk 203a is connected to the inner wall of the annular plate 203f through the connecting block 203g, so that the movable disk 203a on the connecting block 203g can be driven to move synchronously through the movement of the annular plate 203f.

[0036] Specifically, the movable member 204 includes a fixed plate 204a fixedly connected to the inside of the installation groove 201b, and movable openings 204b are provided on both sides of the fixed plate 204a. A movable rod 204c is displaced in the movable opening 204b in the vertical direction. A conical block 204d is fixedly connected to one end of the movable rod 204c, and one end of the conical block 204d is against the upper end surface of the low-position portion 203c. A compression spring 204e is sleeved on the outer wall of the movable rod 204c. The compression spring 204e is a carbon spring with high strength and is convenient for daily work. One end of the compression spring 204e abuts against the lower end surface of the fixed plate 204a, one end of the movable rod 204c is fixedly connected to a clamping block 204f, a limiting block 204g is integrally formed in the movable opening 204b, a surrounding groove 204h is provided on the outer wall of the movable rod 204c, and the limiting block 204g is correspondingly arranged in the surrounding groove 204h, the abutting member 205 includes notches 205a arranged on both sides of the chuck 202b, a clamping groove 205b is provided on one side of the inner wall of the notch 205a, and the clamping block 204f abuts against the clamping groove 205b accordingly.

[0037] Depend on Figures 6 to 9 It can be seen that the fixed plate 204a is a disc-shaped structure, and a movable rod 204c is movably connected to the fixed plate 204a through a compression spring 204e. A block 204f is fixedly connected to the upper end of the movable rod 204c, and a conical block 204d is provided at the other end. The conical block 204d abuts against the upper end surface of the movable disk 203a. At the same time, a limiting block 204g is fixed in the movable opening 204b, and a surrounding groove 204h is provided on the outer wall of the movable rod 204c. The limiting block 204g is correspondingly arranged in the surrounding groove 204h. When the movable rod 204c is displaced in the vertical direction, since the limiting block 204g is fixed, the deflection force of the surrounding groove 204h causes the block 204f on the movable rod 204c to rotate, thereby driving the block 204f to abut against the groove 205b or to disengage from the groove 205b.

[0038] The rest of the structure is the same as that of Example 1.

[0039] In summary, when the first bottom plate 100 and the second bottom plate 101 are fixed, the auxiliary member 301 is first pressed downward, and the auxiliary member 301 and the rotating member 203 move synchronously so that the clamping block 204f corresponds to the position of the notch 205a, and then the chuck 202b and the insertion rod 202c are pressed against the sleeve 201a, and the auxiliary member 301 is released at this time. Under the action of the auxiliary spring 301b, the auxiliary member 301 is driven to reset, thereby driving the annular plate 203f on the connecting block 203g to rotate, and the annular plate 203 When f rotates, the movable disk 203a on the connecting block 203g is driven to rotate, and at this time it transitions from the high-position part 203e to the low-position part 203c, so that the movable rod 204c moves downward under the action of the compression spring 204e. Since the limit block 204g is fixed, the deflection force of the surrounding groove 204h causes the block 204f on the movable rod 204c to rotate. At this time, the block 204f is against the groove 205b, thereby completing the fixation of the first base plate 100 and the second base plate 101.

[0040] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a secondary cable support for a protection chamber, including an auxiliary part 301 of the secondary cable support for the protection chamber in the above embodiment, the auxiliary part 301 includes an annular edge 301a arranged on the outer wall of the sleeve 201a, an auxiliary spring 301b is sleeved on the outer wall of the sleeve 201a, the auxiliary spring 301b is fixedly connected to the annular edge 301a, an annular sleeve 301c is slidably connected to the outer wall of the sleeve 201a, the annular sleeve 301c is connected to the auxiliary spring 301b, a linkage plate 301d is fixedly connected between the annular sleeves 301c on both adjacent sides, the rotating part 203 includes an arc groove 302a arranged on the inner wall of the annular plate 203f, an auxiliary rod 302b is fixedly connected to the bottom end of the annular sleeve 301c, a convex point 302c is integrally formed on the outer wall of the auxiliary rod 302b, and the convex point 302c is correspondingly arranged in the arc groove 302a.

[0041] Depend on Figure 1 , Figures 5 to 9 It can be seen that an annular sleeve 301c is slidably connected to the outer wall of two adjacent groups of sleeves 201a, and a linkage plate 301d is fixedly connected between the two groups of annular sleeves 301c. The linkage plate 301d is fixedly connected to the annular edge 301a through an auxiliary spring 301b. In this way, the annular sleeve 301c is driven to move by the up and down movement of the linkage plate 301d. Since the inner wall of the annular plate 203f is provided with an arc groove 302a, and the protrusion 302c on the outer wall of the auxiliary rod 302b is correspondingly arranged in the arc groove 302a, the deflection force of the arc groove 302a drives the annular plate 203f to rotate.

[0042] The rest of the structure is the same as that of Example 2.

[0043] In summary, when the first base plate 100 and the second base plate 101 need to be disassembled, it is only necessary to pull the linkage plate 301d upwards, and the linkage plate 301d drives the annular sleeve 301c to move upwards. At this time, the auxiliary spring 301b is deformed, and the annular sleeve 301c moves upwards while driving the convex point 302c on the auxiliary rod 302b to move synchronously. Since the convex point 302c is correspondingly arranged in the arc groove 302a, the deflection force of the arc groove 302a drives the annular plate 203f to rotate. At this time, the connecting block 203g is The movable disk 203a rotates, and at this time, it transitions from the low-position part 203c to the high-position part 203e, so that the movable rod 204c moves upward under the action of the compression spring 204e. Since the limit block 204g is fixed, the deflection force of the surrounding groove 204h causes the block 204f on the movable rod 204c to rotate. At this time, the block 204f is disengaged from the slot 205b, completing the unlocking of the first base plate 100 and the second base plate 101. This can save a lot of manpower when the cables need to be returned during the later transformation process.
