Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, specifically a low-voltage conduit and wiring box. Background Technology

[0002] Low-voltage electrical engineering is a category of electrical applications. Electrical applications can be divided into two categories based on the power transmission capacity: high-voltage and low-voltage. Electrical power supply in buildings and building complexes generally refers to low-voltage AC power below 220V 50Hz. It primarily provides electrical energy to people, converting electrical energy into other forms of energy, such as electricity for air conditioning, lighting, and power generation.

[0003] A search revealed a Chinese patent document disclosing an adjustable conduit and wiring box [Announcement No.: CN213959658U]. This box includes a first housing and a second housing. After sequentially installing the sleeve, wiring conduit, and positioning bracket, and locking them with a first screw, rotating either the first or second housing changes the angle between the two wiring conduits to adapt to special installation positions such as corners, ensuring effective protection for the wiring harness at the corner. The first slot, first positioning groove, and limiting block allow for quick positioning during box cover installation and removal, improving efficiency. The second slot, second positioning groove, insert, and positioning block allow for quick insertion of the wiring conduit into the sleeve, improving conduit installation efficiency. The pin, clamp, and torsion spring allow the connector to be clamped, preventing breakage during subsequent conduit and wiring work. This invention can quickly fix the wiring conduit and adjust its position according to the installation environment, greatly improving construction efficiency and demonstrating strong practicality.

[0004] During the process of laying conduits and pulling wires, it is necessary to first cut grooves in the wall for installing junction boxes. Then, the junction boxes are sealed inside the grooves with cement. After one to two days of curing, the wires can be pulled through. However, during the cement curing process, the junction boxes are simply sealed with cement and are prone to shifting within the grooves. This means that the cement cannot effectively fix the junction boxes, and the junction boxes are prone to falling off during subsequent wire pulling, affecting the speed of wire pulling. Utility Model Content

[0005] The purpose of this utility model is to provide a low-voltage wiring box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage wiring box, comprising a box body, a sleeve, and a connecting pipe, wherein the sleeve is threaded to the bottom of the box body, the connecting pipe is fixedly connected to the bottom of the sleeve, and two housings are fixedly connected to the inner wall of the box body, and a mating groove is provided on the side of the two housings that are far apart from each other, and a positioning mechanism is provided inside the mating groove.

[0007] The positioning mechanism includes a support block disposed inside the mating groove. Two springs are fixedly connected to one side of the support block, and two abutting rods are fixedly connected to the other side of the support block. One end of each abutting rod extends through to one side of the wire box body and is fixedly connected to an abutting block.

[0008] An adjustment mechanism is movably disposed inside the mating groove, which can adjust the position of the positioning mechanism according to the size of the groove.

[0009] Preferably, the adjusting mechanism includes a movable block disposed inside the mating groove. One side of the movable block is fixedly connected to one end of a spring, and the other side of the movable block is provided with a bearing, and a threaded rod is rotatably connected to it through the bearing. One end of the threaded rod extends through to one side of the housing, and a threaded hole for cooperating with the threaded rod is provided on one side of the housing.

[0010] Preferably, one end of the threaded rod extends through to one side of the housing and is fixedly connected to a toggle block.

[0011] Preferably, the toggle block has a control groove on its circumferential side, and the inner wall of the control groove has anti-slip texture.

[0012] Preferably, the top and bottom of the movable block are fixedly connected to sliding blocks, and the inner wall of the mating groove is provided with a sliding groove for use with the sliding blocks.

[0013] Preferably, both sides of the abutment block are sloped, and a rubber pad is fixedly connected to the side of the abutment block away from the junction box body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a positioning mechanism, allows the wiring box body to be pushed into the slot by aligning it with the slot. The inclined part of the abutment block will first contact the inner wall of the slot. Under the influence of compression, the abutment block, abutment rod, and support block will move towards the side closer to the spring, compressing the spring. When the wiring box body is fully embedded in the slot, the reaction force generated by the spring pushes the support block, abutment rod, and abutment block away from the spring, so that the side of the abutment block is in close contact with the inner wall of the slot, completing the auxiliary positioning of the wiring box body. When sealing with cement, the wiring box body is less likely to shift, improving the stability of the wiring box body and thus increasing the subsequent wiring speed.

[0016] 2. By setting an adjustment mechanism, this utility model can improve the stability of the wire drawing box body when the abutment block cannot contact the inner wall of the box groove. This is achieved by inserting a finger into the body of the wire drawing box and then rotating the actuating block. The actuating block will drive the threaded rod to rotate inside the threaded hole. The threaded rod will gradually move away from the actuating block. The bearing, the moving block and the positioning structure will also move synchronously. Finally, one side of the abutment block will be in close contact with the inner wall of the box groove, thereby improving the stability of the wire drawing box body. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 6 As shown,

[0026] Example 1:

[0027] A low-voltage wiring box includes a box body 1, a sleeve 2 and a connector 3. The sleeve 2 is threaded to the bottom of the box body 1, and the connector 3 is fixedly connected to the bottom of the sleeve 2. Two housings 4 are fixedly connected to the inner wall of the box body 1. Each of the two housings 4 has a mating groove 5 on the side away from each other, and a positioning mechanism is provided inside the mating groove 5.

[0028] The positioning mechanism includes a support block 6 disposed inside the mating groove 5. Two springs 7 are fixedly connected to one side of the support block 6, and two abutting rods 8 are fixedly connected to the other side of the support block 6. One end of the abutting rod 8 extends through to one side of the wire box body 1 and is fixedly connected to an abutting block 9.

[0029] The adjustment mechanism is located inside the mating groove 5 and can adjust the position of the positioning mechanism according to the size of the groove.

[0030] In this embodiment, considering that during the cement solidification process, the junction box is simply sealed with cement, which can easily cause it to shift within the box slot. This results in the cement failing to effectively fix the junction box body 1, making it prone to falling off during subsequent wire threading and affecting the threading speed. Therefore, a positioning mechanism is set up. During use, by aligning the junction box body 1 with the box slot, the junction box body 1 is pushed into the box slot. The sloping part of the abutment block 9 will first contact the inner wall of the box slot. Under the influence of compression, the abutment block 9, abutment rod 8, and support block 6 will move towards the side closer to the spring 7, compressing the spring 7. When the junction box body 1 is fully embedded in the box slot, the reaction force generated by the spring 7 pushes the support block 6, abutment rod 8, and abutment block 9 away from the spring 7, making the side of the abutment block 9 in close contact with the inner wall of the box slot, thus completing the auxiliary positioning of the junction box body 1. After that, when sealing with cement, the junction box body 1 is less likely to shift, improving the stability of the junction box body 1 and thereby increasing the subsequent wire threading speed.

[0031] Both sides of the abutment block 9 are sloping, and a rubber pad 19 is fixedly connected to the side of the abutment block 9 away from the main body 1 of the junction box.

[0032] In this embodiment, by setting the rubber pad 19, the contact area between the abutment block 9 and the inner wall of the box groove can be increased, thereby further improving the stability of the junction box after it is embedded.

[0033] Example 2:

[0034] Based on Embodiment 1, in this embodiment, the positioning mechanism can push four abutment blocks 9 against the inner wall of the slot through the elastic force generated by the spring 7, thereby improving the stability of the junction box body 1. However, considering that the precision of the worker's slotting may have a slight deviation, the slot may be slightly larger or smaller. If the spring 7 pushes the abutment blocks 9 to not make close contact with the inner wall of the slot, it will also affect the stability of the junction box. In this application, the adjustment mechanism includes a moving block 10 disposed inside the mating slot 5. One side of the moving block 10 is fixedly connected to one end of the spring 7, and the other side of the moving block 10 is provided with a bearing 11, and a threaded rod 12 is rotatably connected through the bearing 11. One end of the threaded rod 12 passes through to one side of the housing 4, and a threaded hole 13 is provided on one side of the housing 4 to cooperate with the threaded rod 12.

[0035] In this embodiment, by setting an adjustment mechanism, when the abutment block 9 cannot contact the inner wall of the box groove, a finger can be inserted into the wire-threading box body 1, and then the actuating block 14 can be rotated. The actuating block 14 will drive the threaded rod 12 to rotate inside the threaded hole 13. The threaded rod 12 will gradually move away from the actuating block 14, and the bearing 11, the moving block 10, and the positioning structure will also move synchronously. Figure 2 As shown, the final abutment block 9 can be in close contact with the inner wall of the box groove to further improve the stability of the wire box body 1;

[0036] It should be noted that the reverse rotation of the toggle block 14 can move the abutment block 9 to the side closer to the toggle block 14. If you want to ensure that the wire box body 1 is in the center of the box groove, you need to adjust the adjustment structure on both sides respectively.

[0037] One end of the threaded rod 12 extends through to one side of the housing 4 and is fixedly connected to a toggle block 14.

[0038] In this embodiment, by setting a toggle block 14, when the user needs to rotate the threaded rod 12 to adjust the position of the positioning mechanism, a leverage point is provided for the user's fingers, so that the user can easily rotate the toggle block 14 to drive the threaded rod 12 to rotate, which facilitates driving.

[0039] The circumferential side of the toggle block 14 is provided with a control groove 15, and the inner wall of the control groove 15 is provided with anti-slip texture 16.

[0040] In this embodiment, by setting the control groove 15 and the anti-slip texture 16, the friction between the finger and the toggle block 14 can be increased through the design of the control groove 15 and the anti-slip texture, thus playing an anti-slip role.

[0041] The top and bottom of the movable block 10 are fixedly connected with sliding blocks 17, and the inner wall of the mating groove 5 is provided with a sliding groove 18 that is used in conjunction with the sliding blocks 17.

[0042] In this embodiment, by setting the sliding block 17 and the sliding groove 18, when the threaded rod 12 rotates to transmit power to the moving block 10, the moving block 10 is restricted to move only along the trajectory of the sliding block 17 and the sliding groove 18, which plays the role of restricting the movement trajectory and improving its stability during the movement process.

[0043] Working principle: During use, by aligning the position of the junction box body 1 with the slot, the junction box body 1 is pushed into the slot. The sloping part of the abutment block 9 will first contact the inner wall of the slot. Under the influence of compression, the abutment block 9, the abutment rod 8, and the support block 6 will move towards the side closer to the spring 7, so that the spring 7 is in a compressed state. When the junction box body 1 is fully embedded in the slot, the reaction force generated by the spring 7 pushes the support block 6, the abutment rod 8, and the abutment block 9 to the side away from the spring 7, so that the side of the abutment block 9 is in close contact with the inner wall of the slot, thus completing the auxiliary positioning of the junction box body 1. After that, when sealing with cement, the junction box body 1 is less likely to shift, improving the stability of the junction box body 1 and thus improving the subsequent wire threading speed.

[0044] When the abutment block 9 cannot contact the inner wall of the slot, by inserting a finger into the wire guide box body 1 and then rotating the actuating block 14, the actuating block 14 will drive the threaded rod 12 to rotate inside the threaded hole 13. The threaded rod 12 will gradually move away from the actuating block 14, and the bearing 11, the moving block 10, and the positioning structure will also move synchronously. Figure 2 As shown, the final abutment block 9 can be in close contact with the inner wall of the box groove to further improve the stability of the wire box body 1.
