Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried slots for weak electric wires, and more specifically, to concealed pre-buried slots for weak electric wires. Background Art

[0002] During the construction of some buildings, pre-buried grooves are set up on the walls to conceal weak wires, so that the weak wires will not be located on the outside of the wall and affect the normal use of the room, thereby improving the overall aesthetics and protecting the weak wires from damage caused by external collisions. After the weak wires are buried in the pre-buried grooves, they are sealed with concrete, but this causes the concrete to directly contact the weak wires, which causes the pressure inside the wall to directly act on the weak wires, which may cause damage to the weak wires, thus affecting normal use. Utility Model Content

[0008] As a preferred technical solution of the present invention, the reinforcing rib is T-shaped, and the reinforcing plate is a rectangular body.

[0009] As a preferred technical solution of the present invention, the reinforcing ribs and the reinforcing plate are both fixed inside the wall, and the mounting tube is located in the middle of the fixing plate.

[0010] As a preferred technical solution of the present invention, the top end of the fixed plate is fixedly connected to a guide plate, a smooth angle is provided at the connection between the guide plate and the fixed plate, and the guide plate is fixedly connected to the fixed plate at an angle.

[0011] As a preferred technical solution of the present invention, an anti-slip groove is provided on a side of the fixing plate away from the mounting tube, and the anti-slip groove is vertically provided on the side of the fixing plate away from the mounting tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model opens a pre-buried groove in the middle of the wall, then installs the installation tube and the installation plate inside the pre-buried groove, then conveys the weak wires along the guide plate between the two fixed plates, and then stretches the two fixed plates toward the installation tube.

[0021] The following will be combined with the 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.

[0022] like Figures 1 to 5 As shown, the utility model provides a concealed weak wire embedded groove, including a wall 1, a pre-buried groove 14 is opened in the middle of the wall 1, and mounting tubes 2 are provided on both sides of the pre-buried groove 14. A mounting plate 3 is fixedly connected to one side of the mounting tube 2 near the center of the pre-buried groove 14, a damping telescopic rod 4 is fixedly connected to the inner cavity of the mounting tube 2, a compression spring 5 is fixedly connected to the side of the inner cavity of the mounting tube 2 near the mounting plate 3, a fixing plate 6 is fixedly connected to the side of the compression spring 5 near the mounting plate 3, and a blocking plate 13 is provided on the side of the mounting plate 3 away from the wall 1;

[0023] By opening a pre-buried groove 14 in the middle of the wall 1, the mounting tube 2 and the mounting plate 3 are then installed inside the pre-buried groove 14, and then the weak wires are conveyed between the two fixed plates 6 along the guide plate 8, and then the two fixed plates 6 are stretched toward the mounting tube 2. When the fixed plate 6 moves toward the mounting tube 2, it drives the damping telescopic rod 4 and the compression spring 5 to contract. At this time, the reaction force of the compression spring 5 drives the fixed plate 6 to clamp the weak wires. After the weak wires are installed, the blocking plate 13 is connected to the mounting plate 3, and then concrete is laid on the outside of the blocking plate 13, thereby isolating the concrete through the mounting plate 3 and the blocking plate 13, avoiding direct contact between the concrete and the weak wires, causing the weak wires to be damaged by the stress of the concrete, and completing the installation and fixation of the weak wires through the damping telescopic rod 4 and the compression spring 5, avoiding the situation where the weak wires shake in the inner cavity of the mounting plate 3 and affect their use.

[0024] Among them, the outer side of the installation tube 2 is fixedly connected with a reinforcement plate 10, and the side of the installation plate 3 close to the wall 1 is fixedly connected with a reinforcement rib 11;

[0025] By installing the reinforcing plate 10 on the outside of the tube 2, the mounting tube 2 can be connected to the wall 1 through the reinforcing plate 10, thereby improving the stability of the connection between the mounting tube 2 and the concrete, and then by setting the reinforcing ribs 11, the stability of the connection between the mounting plate 3 and the wall 1 is improved, thereby achieving the improvement of the stability of the connection between the mounting plate 3 and the wall 1 through the reinforcing plate 10 and the reinforcing ribs 11, thereby improving the stability of the fixing plate 6 when fixing the weak wires.

[0026] Among them, a threaded hole is opened on one side of the mounting plate 3 close to the blocking plate 13, and the inner cavity of the blocking plate 13 is threadedly connected with a mounting bolt 12, and the blocking plate 13 is threadedly connected to the mounting plate 3 through the mounting bolt 12;

[0027] Through the threaded hole on the side of the mounting plate 3 close to the blocking plate 13, the blocking plate 13 can be threadedly connected to the mounting plate 3 through the mounting bolts 12, so that the concrete can be isolated on the outside through the blocking plate 13 and the mounting plate 3, and the blocking plate 13 can be separated from the mounting plate 3 before installation. After the low-voltage wires are installed, the blocking plate 13 and the mounting plate 3 can be connected.

[0028] The damping telescopic rod 4 is located at the center of the inner cavity of the compression spring 5, and the side of the damping telescopic rod 4 away from the mounting tube 2 is fixedly connected to the fixing plate 6;

[0029] After the fixing plate 6 is squeezed by the weak wire, it drives the fixing plate 6 to move toward the mounting tube 2, causing the compression spring 5 to contract and store force, thereby generating a reaction force to drive the fixing plate 6 to clamp the weak wire, and then the fixing plate 6 is positioned and guided by the damping telescopic rod 4, thereby preventing the fixing plate 6 from deflecting during the movement.

[0030] The reinforcing rib 11 is T-shaped and the reinforcing plate 10 is a rectangular body;

[0031] By making the reinforcing rib 11 into a T-shape, the reinforcing rib 11 has sufficient stability when located in the inner cavity of the wall 1, so that the mounting plate 3 also has sufficient stability after installation. Furthermore, by providing the reinforcing plate 10, the stability of the mounting tube 2 when installed in the inner cavity of the wall 1 is also improved.

[0032] The reinforcing ribs 11 and the reinforcing plate 10 are fixed inside the wall 1, and the mounting tube 2 is located in the middle of the fixing plate 6;

[0033] The reinforcing ribs 11 and the reinforcing plate 10 are fixed to the inside of the wall 1, so that the reinforcing plate 10 and the reinforcing ribs 11 can fix the mounting tube 2 and the mounting plate 3. Then, the mounting tube 2 is located in the middle of the fixing plate 6, so that the damping telescopic rod 4 and the compression spring 5 in the inner cavity of the mounting tube 2 are fixedly connected to the fixing plate 6 from the middle of the fixing plate 6.

[0034] Among them, the top of the fixed plate 6 is fixedly connected with a guide plate 8, and the connection between the guide plate 8 and the fixed plate 6 is provided with a smooth corner 9, and the guide plate 8 is fixedly connected to the fixed plate 6 at an angle;

[0035] By setting the guide plate 8, the weak wire can enter between the two fixed plates 6 along the guide plate 8, so that the weak wire is clamped by the two fixed plates 6, and then by setting the smooth angle 9, the smoothness of the weak wire is improved when it enters between the two fixed plates 6 along the guide plate 8.

[0036] Among them, the side of the fixing plate 6 away from the installation tube 2 is provided with an anti-slip groove 7, and the anti-slip groove 7 is vertically provided on the side of the fixing plate 6 away from the installation tube 2;

[0037] The anti-slip groove 7 is arranged vertically so that when the weak wire is inserted downward from the top of the fixed plate 6, the anti-slip groove 7 will not generate a high friction force on the weak wire. When the weak wire is laterally offset, the anti-slip groove 7 can increase the friction force to prevent the weak wire from deviating.

[0038] The working principle and use process of the utility model are as follows: a pre-buried groove 14 is opened on the surface of the wall 1, and the mounting plate 3 is located in the inner cavity of the pre-buried groove 14 and fixedly connected to the wall 1 through the reinforcing ribs 11. At this time, the mounting tube 2 is located on both sides of the inner cavity of the pre-buried groove 14 and fixedly connected to the wall 1 through the reinforcing plate 10;

[0039] Then, the weak wire is inserted from above the two guide plates 8 and is located between the two fixing plates 6 along the smooth angle 9, so that the anti-slip groove 7 is in contact with the outer side of the weak wire. At this time, the width of the weak wire drives the two fixing plates 6 to move toward the two mounting plates 3, thereby driving the damping telescopic rod 4 and the compression spring 5 to contract. The contraction of the damping telescopic rod 4 and the compression spring 5 generates a reaction force, which drives the fixing plate 6 to press and fix the weak wire through the anti-slip groove 7.

[0040] After the installation is completed, the blocking plate 13 is threadedly connected to the mounting plate 3 through the mounting bolts 12 to block the mounting plate 3, and then concrete is buried on the outside of the blocking plate 13 to complete the pre-embedding of the weak wires.
