Description

Technical Field

[0001] This utility model relates to the field of control box technology, and in particular to a fire-fighting linkage control box. Background Technology

[0002] Fire alarm linkage control refers to the automatic shutdown of relevant air conditioners in the alarm area, closing fire dampers on pipes, stopping relevant ventilation fans, opening smoke exhaust valves on relevant pipes, automatically closing electric fire doors and fire-resistant roller shutters in relevant areas, sequentially cutting off non-fire-fighting power supplies, turning on emergency lighting and evacuation signs, and shutting down all elevators except fire elevators after a fire detector detects a fire signal. This control is achieved through a controller in the control center, which is connected to the electric fire doors and other equipment via electrical wires.

[0003] The existing control box requires inserting the metal end of the wire into the wiring hole on the terminal block and clamping and positioning the wire one by one during installation and wiring. This operation is cumbersome and not conducive to the overall installation of the control box. Utility Model Content

[0004] To solve the above problems, this utility model provides a fire-fighting linkage control box.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fire-fighting linkage control box, including a control box body and a detection door hinged to the control box body. A terminal block is fixed inside the control box body. A positioning plate that fits against the terminal block is provided on the terminal block. A first arc groove is opened on the top of the terminal block. A second arc groove communicating with the first arc groove is opened on the top of the positioning plate. A clamping assembly is provided on the positioning plate. The clamping assembly includes a clamping block disposed in the second arc groove. A conductive sheet is fixed on the inner wall of the first arc groove. The conductive sheet and the clamping block are used to clamp the metal end of the wire. The number of clamping blocks, the number of second arc grooves, the number of first arc grooves, and the number of conductive sheets are all equal and their positions correspond one-to-one. A positioning assembly for fixing the terminal block and the positioning plate and limiting the positioning plate is jointly provided on the positioning plate and the terminal block.

[0006] By adopting the above technical solution, during the wire wiring process, the positioning component makes the terminal block and the positioning plate contact and fix them, and then separates the terminal block and the positioning plate. At this time, the metal end of the wire is inserted one by one between the first and second arc grooves until the metal end can no longer move. At this time, the metal end of the wire is located between the conductive plate and the clamping component, and the side wall of the metal end is in contact with the side wall of the conductive plate and the clamping block. Then, the positioning component fixes the terminal block and the positioning plate, and the terminal block and the positioning plate are in close contact with each other. The conductive plate and the clamping block clamp the metal end of the wire, thus completing the wiring of multiple wires, eliminating the cumbersome operation of the existing technology, and improving the installation efficiency of the control box.

[0007] Furthermore, the positioning components are provided in two sets and symmetrically arranged about the center of the positioning plate. The positioning components include positioning blocks fixed on the terminal block. The side wall of the positioning block near the detection door is provided with a plug groove. The positioning components also include plug blocks fixed on the positioning plate and plugging into the plug groove, a vertical plate fixed on the plug blocks and having elasticity, and a plug strip fixed on the vertical plate. The side wall of the positioning block away from the terminal block is provided with a plug-in through hole that plugs into the plug strip.

[0008] By employing the above technical solution, pressing the insert bar moves it towards the vertical plate, causing the vertical plate to deform under force until it separates from the insertion hole. At this point, the insert block can be pulled towards the detection door, thus separating the terminal block from the positioning plate. Similarly, pressing the insert block moves the vertical plate and insert bar away from the detection door until the insert bar reaches the insertion hole. At this point, the vertical plate gradually deforms and resets, and the insert bar reconnects with the insertion hole, thus achieving the connection between the terminal block and the positioning plate.

[0009] Furthermore, a flexible limiting plate is fixed inside the control box, located above the terminal block. A limiting through hole for clamping the insulated end of the wire is provided through the top of the limiting plate. The side wall of the limiting through hole abuts against the outer wall of the insulated end of the wire. A connecting through hole communicating with the limiting through hole is provided on the side wall of the limiting plate near the detection door. The distance between the side walls on both sides of the connecting through hole gradually increases from the first arc groove to the second arc groove. The number of limiting through holes, the number of connecting through holes, the number of limiting plates and the number of first arc grooves are all equal and their positions correspond one-to-one.

[0010] By adopting the above technical solution, during the wire wiring process, the insulated end of the wire is inserted into the limiting through hole through the connecting through hole. The side wall of the limiting through hole is close to the side wall of the wire, which reduces the probability that the metal end of the wire will fall off between the first and second arc grooves.

[0011] Furthermore, a mounting shell is fixed on the side wall of the positioning plate near the detection door. A sliding through hole communicating with the second arc groove is provided through the side wall of the positioning plate near the detection door. The clamping block is slidably connected in the sliding through hole. The clamping assembly also includes a threaded post rotatably mounted on the side wall of the clamping block away from the first arc groove. The top of the clamping block is flush with the top of the second arc groove. The threaded post passes through the mounting shell and is threadedly connected. The number of sliding through holes is equal to the number of the second arc groove, and their positions correspond one-to-one.

[0012] By adopting the above technical solution, the rotating threaded column, due to the sliding connection between the clamping block and the sliding through hole, the threaded column is rotatably connected to the clamping block, thereby causing the clamping block to rise or fall, enabling the installation or removal of a single wire.

[0013] Furthermore, a spring in a retracted state is fixed between the side wall of the insertion block away from the detection gate and the inner side wall of the positioning block.

[0014] By adopting the above technical solution, after the insert strip separates from the insertion hole, the spring gradually extends, causing the insert block connected to the spring, the vertical plate connected to the insert block, and the insert strip connected to the vertical plate to move towards the detection door, which facilitates the separation operation of the wiring terminal and the positioning plate.

[0015] Furthermore, a sliding rod is fixed to the bottom of the insertion block, the sliding rod passes through the positioning block and slides in engagement, and a limit block is fixed to the end of the sliding rod away from the detection door.

[0016] By adopting the above technical solution, the setting of the slide bar and the limiting block improves the stability of the spring during movement.

[0017] Furthermore, the clamping assembly also includes a stop block fixedly sleeved on the threaded post.

[0018] By adopting the above technical solution, the setting of the stop block prevents the clamping block from falling out of the sliding through hole when it rises.

[0019] Furthermore, a rectangular groove communicating with the limiting through hole is provided through the top of the limiting plate.

[0020] By adopting the above technical solution, the elasticity of the limiting plate is improved, so that the insulated end of the cable can pass into the limiting through hole.

[0021] In summary, the present invention has the following beneficial effects: In this application, by setting up a terminal block, a positioning plate, a first arc groove, a second arc groove and a positioning component, the cumbersome operation of the prior art is eliminated, and the installation efficiency of the control box is improved.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4 As shown in the embodiment of this application, a fire alarm control box is disclosed, including a control box body 1, a positioning component 7, and a clamping component 11. A through-hole for wiring is provided through the bottom of the control box body 1, and a detection door is hinged to the control box body 1. A terminal block 2 is fixed inside the control box body 1, and a positioning plate 3 is provided on the terminal block 2, which is in contact with the terminal block 2. A mounting shell 9 is fixed on the side wall of the positioning plate 3 near the detection door, and a sliding through-hole 10 communicating with a second arc groove 5 is provided through the side wall of the positioning plate 3 near the detection door. A first arc groove 4 is formed on the top of the terminal block 2, and a second arc groove 5 communicating with the first arc groove 4 is formed on the top of the positioning plate 3. A conductive sheet 6 is fixed on the inner wall of the first arc groove 4, and a clamping component 11 is provided on the positioning plate 3. The clamping component 11 includes a clamping block 111, a threaded post 112, and a stop block 113, with the clamping block 111 disposed within the second arc groove 5. The conductive sheet 6 and the clamping block 111 are used to clamp the metal end of the wire. The number of clamping blocks 111, the number of second arc grooves 5, the number of first arc grooves 4 and the number of conductive sheets 6 are all equal and their positions correspond one-to-one.

[0029] During the wiring process, the positioning component 7 fixes the terminal block 2 and the positioning plate 3 in contact and then separates them. At this time, the metal ends of the wires are inserted one by one between the first arc groove 4 and the second arc groove 5 until the metal ends can no longer move. At this point, the metal ends of the wires are located between the conductive plate 6 and the clamping component 11, and the sidewalls of the metal ends are all in contact with the sidewalls of the conductive plate 6 and the clamping block 111. Then, the positioning component 7 fixes the terminal block 2 and the positioning plate 3, and the terminal block 2 and the positioning plate 3 are in close contact with each other. The conductive plate 6 and the clamping block 111 clamp the metal ends of the wires, thus completing the wiring of multiple wires. This eliminates the cumbersome operation of the existing technology and improves the installation efficiency of the control box.

[0030] Positioning components 7 are jointly mounted on the terminal block 2 and the positioning plate 3. Positioning components 7 are used to fix the terminal block 2 and the positioning plate 3 and to limit the positioning plate 3. Two sets of positioning components 7 are symmetrically arranged about the center of the positioning plate 3. Each positioning component 7 includes a positioning block 71, an insert block 72, a vertical plate 73, and an insert strip 74. The positioning block 71 is fixed to the terminal block 2, and a insertion groove is formed on the side wall of the positioning block 71 near the detection gate. The insert block 72 is fixed to the positioning plate 3 and engages with the insertion groove. The vertical plate 73 is fixed to the insert block 72 and is elastic. The insert strip 74 is fixed to the vertical plate 73. A through hole 75 is provided on the side wall of the positioning block 71 away from the terminal block 2, which engages with the insert strip 74. Pressing the insert 74 moves it towards the vertical plate 73, causing the vertical plate 73 to deform under force until it separates from the insertion hole 75. At this point, the insert block 72 can be pulled towards the detection door, thus separating the terminal block 2 from the positioning plate 3. Similarly, pressing the insert block 72 moves the vertical plate 73 and the insert 74 away from the detection door until the insert 74 reaches the insertion hole 75. At this point, the vertical plate 73 gradually deforms and resets, and the insert 74 reconnects with the insertion hole 75, thus achieving the connection between the terminal block 2 and the positioning plate 3.

[0031] A flexible limiting plate 8 is fixed inside the control box 1, located above the terminal block 2. A limiting through hole 81 for clamping the insulated end of the wire is provided through the top of the limiting plate 8. The side wall of the limiting through hole 81 abuts against the outer wall of the insulated end of the wire. A connecting through hole 82 communicating with the limiting through hole 81 is provided on the side wall of the limiting plate 8 near the detection door. The distance between the side walls on both sides of the connecting through hole 82 gradually increases from the first arc groove 4 to the second arc groove 5. The number of limiting through holes 81, the number of connecting through holes 82, the number of limiting plates 8, and the number of first arc grooves 4 are all equal and their positions correspond one-to-one. During wire wiring, the insulated end of the wire is inserted into the limiting through hole 81 through the connecting through hole 82. The side wall of the limiting through hole 81 is in close contact with the side wall of the wire, reducing the probability of the metal end of the wire falling out between the first arc groove 4 and the second arc groove 5.

[0032] The clamping block 111 is slidably connected within the sliding through hole 10, and the threaded post 112 is rotatably mounted on the side wall of the clamping block 111 away from the first arc groove 4. The top of the clamping block 111 is flush with the top of the second arc groove 5. The side wall of the clamping block 111 away from the detection door and the threaded post 112 penetrate the mounting shell 9 and are threadedly connected. The number of sliding through holes 10 and the number of second arc grooves 5 are equal and their positions correspond one-to-one. By rotating the threaded post 112, since the clamping block 111 is slidably connected to the sliding through hole 10, the threaded post 112 is rotatably connected to the clamping block 111, thereby causing the clamping block 111 to rise or fall, enabling the installation or removal of a single wire.

[0033] A spring 12 in a retracted state is fixed between the side wall of the insertion block 72 away from the detection door and the inner side wall of the positioning block 71. After the insertion strip 74 separates from the insertion through hole 75, the spring 12 gradually extends, causing the insertion block 72 connected to the spring 12, the vertical plate 73 connected to the insertion block 72, and the insertion strip 74 connected to the vertical plate 73 to move towards the detection door, facilitating the separation operation of the terminal block 2 and the positioning plate 3.

[0034] A sliding rod 13 is fixed to the bottom of the insertion block 72. The sliding rod 13 passes through the positioning block 71 and slides in cooperation with it. A limit block 14 is fixed to the end of the sliding rod 13 away from the detection door.

[0035] The stop block 113 is fixedly sleeved on the threaded post 112. The sliding rod 13 and the limiting block 14 improve the stability of the spring 12 during movement.

[0036] A rectangular groove 83 communicating with the limiting through hole 81 is provided through the top of the limiting plate 8. This improves the elasticity of the limiting plate 8 so that the insulated end of the cable can pass into the limiting through hole 81.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
