DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1 to 5 The utility model is a protective device for building electrical installation, including a placement frame 1 and a protective shell 101 installed in the middle of its upper surface. Both sides of the upper surface of the placement frame 1 are connected to the mounting base 103 by fixing bolts. A through slot 103a is opened inside the mounting base 103, and a T-shaped slot 103b is provided at the top front end of the mounting base 103. A docking assembly 2 is provided inside the through slot 103a; the docking assembly 2 includes a rotating shaft 203 rotatably connected to the inside of the through slot 103a, and a first connecting rod 201a and a second connecting rod 202a fixedly connected to the top and bottom of the outer wall of the rotating shaft 203.

[0032] Specifically, the inner sides of the protective shell 101 are slidably connected with extension tubes 102, the outer wall of the extension tube 102 is fixedly connected with a docking ring 102a, the bottom of the outer wall of the docking ring 102a is provided with a card slot 102b, the top rear end of the mounting seat 103 is movably connected to the flip cover 104 through a hinge, the bottom front end of the flip cover 104 is fixedly connected with a plug plate 104a, one end of the first connecting rod 201a and the second connecting rod 202a are fixedly connected with a card plate 205, the outer side of the outer wall of the rotating shaft 203 is provided with a torsion spring 204, the other end of the first connecting rod 201a is fixedly connected to the first pressure block 201, and the other end of the second connecting rod 202a is fixedly connected to the second pressure block 202.

[0033] Furthermore, the protective shell 101 and the mounting base 103 are both mounted on the surface of the placement rack 1 by fixing bolts. The first connecting rod 201a and the second connecting rod 202a rotate around the rotating shaft 203 as the center when subjected to force. The extension tube 102 can slide inside the protective shell 101 to adjust its position. The flip cover 104 can be flipped over by the action of the hinge. The cross-section of the card plate 205 is L-shaped, and the elastic performance of the torsion spring 204 can drive the first connecting rod 201a and the second connecting rod 202a to rotate around the rotating shaft 203 as the center.

[0034] The operation process of this embodiment is as follows: when protecting the building electrical cables, first insert the cables into the protective shell 101, then pull the extension tubes 102 at both ends outward, and the extension tube 102 will slide inside the protective shell 101 under the force and move to both sides. Then, the docking ring 102a on the outside of the extension tube 102 can be tightly attached to the surface of the mounting seat 103, and the two sets of clamping plates 205 are inserted into the clamping groove 102b on the docking ring 102a to play a limiting role, thereby completing the fixed limit of the position of the extension tube 102. When the extension tube 102 needs to be opened, the first and second pressure blocks 201 and 202 at the front and rear are pushed toward the middle. 202, and the inner walls of the first pressing block 201 and the second pressing block 202 are connected to the corresponding card plate 205 through the first connecting rod 201a and the second connecting rod 202a respectively. Therefore, under the transmission action of the first pressing block 201 and the second pressing block 202, the first connecting rod 201a and the second connecting rod 202a can be made to rotate with the rotating shaft 203 as the center and squeeze the torsion spring 204. At this time, the limiting effect of the card plate 205 on the card slot 102b can be cancelled, and then the extension tube 102 can be pushed into the interior of the protective shell 101, which makes it convenient for the staff to quickly adjust the position of the extension tube 102, saving time and effort and improving work efficiency.

[0035] Example 2, please refer to Figure 3 and Figure 6 On the basis of Example 1, what is different from the first embodiment is that: a limit assembly 3 is provided inside the T-slot 103b, and the limit assembly 3 includes a push block 301 with a gap installed on the outside of the T-slot 103b, and a third connecting rod 302 fixedly connected to the inner wall of the push block 301 in an array along the horizontal direction. This solves the problem that the existing protective device for building electrical installation uses an adjustment mechanism to push the stabilizing block upward to cooperate with the arc block to suppress the cable during use. However, this method is cumbersome and time-consuming and labor-intensive during the operation of the staff, resulting in low work efficiency.

[0036] Specifically, the other end of the third connecting rod 302 passes through the through hole on the T-slot 103b and the through hole on the fixed plate 303 in sequence and is connected to the baffle 305. A spring 304 is sleeved on the outer side of the outer wall of the third connecting rod 302. The spring 304 is located on the bracket of the fixed plate 303 and the baffle 305. The outer wall of the fixed plate 303 is fixed on the inner wall of the T-slot 103b.

[0037] Furthermore, the push block 301 and the baffle 305 are connected by a third connecting rod 302 to play a role of connecting transmission. Under the elastic performance of the spring 304, the baffle 305 can be driven to move. The third connecting rod 302 is L-shaped.

[0038] After the cam 104 is unlocked, the cam 104 is unlocked and the cam 104 is unlocked, and the cam 104 is unlocked, so that the cam 104 is unlocked.
