Therefore, during disassembly, multiple adjusting nuts need to be turned to completely disassemble the low-voltage engineering conduit, which is quite laborious. Especially when disassembling multiple sections of low-voltage engineering conduit, the workload is large and the labor intensity is high. Therefore, a quick connection method for low-voltage engineering conduit is proposed to solve the above problems. Utility Model Content

[0004] To address the issue that disassembling low-voltage electrical conduits requires turning multiple adjusting nuts, which is labor-intensive, especially when disassembling multiple sections of conduit, this application provides a method for quickly connecting low-voltage electrical conduits.

[0005] This application provides a quick-connection technical solution for low-voltage electrical wiring conduits, using the following approach:

[0006] A quick-connection low-voltage engineering conduit includes a conduit body, one end of which is fixedly connected to a connector, and the other end of which is fixedly connected to a retaining seat.

[0008] The quick-release mechanism also includes a rotating shaft rotatably connected to the outer wall of the middle of the connecting seat. A gear is fixedly connected to the outer wall of the rotating shaft. A knob is fixedly connected to the end of the rotating shaft away from the connecting seat. A connecting plate is welded to the outer wall of the middle section of the two movable blocks. A rack is welded to the end of the two connecting plates away from the movable blocks. Both racks mesh with the gear.

[0009] Preferably, the fixing frame includes two limiting rods and a limiting plate. The limiting rods are welded to the outer wall of the connecting seat, and the limiting plate is fixedly connected to the end of the two limiting rods away from the connecting seat.

[0010] Preferably, the movable block is slidably connected to the outer wall of the two limiting rods, and the spring is sleeved on the outer wall of the two limiting rods, with one end of the spring abutting against the movable block and the other end abutting against the limiting plate.

[0011] Preferably, the outer wall of the card holder has two symmetrical card slots, and the two card slots are engaged with two card blocks.

[0012] Preferably, the inner wall of the connector is fixedly connected to two positioning blocks, which are arranged perpendicularly to the two locking blocks. The outer wall of the locking block has two positioning grooves, which are adapted to and inserted into the two positioning blocks.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a method for quickly connecting low-voltage electrical wiring conduits. (Refer to...) Figure 1-5 A quick-connection low-voltage engineering conduit includes a conduit body 1, one end of which is fixedly connected to a connector 2, and the other end is fixedly connected to a retaining seat 3. The connector 2 and the retaining seat 3 are adapted to be inserted into each other, and a quick-release mechanism is installed on the outer wall of the connector 2.

[0024] The quick-release mechanism includes two fixed brackets 8 symmetrically fixedly connected to the outer wall of the connecting seat 2. Movable blocks 11 are installed on the outer wall of the two fixed brackets 8. A locking block 5 is fixedly connected to the outer wall of the movable block 11 facing the connecting seat 2. The end of the locking block 5 away from the movable block 11 passes through and extends into the inner cavity of the connecting seat 2. Two springs 12 are installed on the outer wall of the fixed brackets 8. Two locking slots 4 are symmetrically opened on the outer wall of the locking seat 3. The two locking slots 4 are correspondingly engaged with the two locking blocks 5.

[0025] The quick-release mechanism also includes a rotating shaft 15 rotatably connected to the outer wall of the middle section of the connecting seat 2. A gear 16 is fixedly connected to the outer wall of the rotating shaft 15. A knob 17 is fixedly connected to the end of the rotating shaft 15 away from the connecting seat 2. A connecting plate 13 is welded to the outer wall of the middle section of the two movable blocks 11. A rack 14 is welded to the end of the two connecting plates 13 away from the movable blocks 11. Both racks 14 mesh with the gear 16.

[0026] The fixing frame 8 includes two limiting rods 9 and a limiting plate 10. The limiting rods 9 are welded to the outer wall of the connecting seat 2, and the limiting plate 10 is fixedly connected to the end of the two limiting rods 9 away from the connecting seat 2.

[0027] The movable block 11 is slidably connected to the outer wall of the two limiting rods 9, and the spring 12 is sleeved on the outer wall of the two limiting rods 9. One end of the spring 12 abuts against the movable block 11, and the other end abuts against the limiting plate 10.

[0028] The inner wall of the connector 2 is fixedly connected to two positioning blocks 7, which are arranged perpendicularly to the two locking blocks 5. The outer wall of the locking seat 3 has two positioning grooves 6, which are adapted to and inserted into the two positioning blocks 7.

[0029] Two limiting blocks 18 are fixedly connected to the outer wall of the connecting seat 2. The rack 14 is located between the limiting block 18 and the gear 16. The limiting block 18 limits the rack 14, so that the rack 14 is always located between the limiting block 18 and the gear 16 when it moves, and maintains meshing transmission with the gear 16.

[0030] The implementation principle of a quick connection method for low-voltage engineering conduits in this application embodiment is as follows: During installation, the retaining seat 3 at one end of one conduit 1 is inserted into the connecting seat 2 at one end of another conduit 1. During insertion, the positioning block 7 aligns with the positioning groove 6 to provide positioning. When the positioning block 7 and the positioning groove 6 are aligned, the retaining groove 4 and the retaining block 5 also correspond. When the retaining seat 3 enters the inner wall of the connecting seat 2, the positioning groove 6 is inserted into the positioning block 7. At the same time, the outer wall of the retaining seat 3 moves downward to press the two retaining blocks 5. The inclined ends of the two retaining blocks 5 are then connected. The two locking blocks 5 can be easily pushed outward, and the two locking blocks 5 push the two movable blocks 11 to slide on the outer wall of the limiting rod 9 and squeeze the spring 12. The spring 12 deforms and generates elastic force. When the locking seat 3 is fully inserted into the inner wall of the connecting seat 2, the locking groove 4 facilitates the alignment of the locking blocks 5. The outer wall of the locking seat 3 no longer squeezes the locking blocks 5. Under the elastic force of the spring 12, the movable block 11 drives the locking blocks 5 to reset. The locking blocks 5 re-extend into the connecting seat 2 and engage with the locking groove 4, thereby locking the locking seat 3 in the connecting seat 2 and completing the installation.

[0031] During disassembly, simply rotate the knob 17 counterclockwise. The knob 17 drives the rotating shaft 15 to rotate, which in turn drives the gear 16 to rotate counterclockwise. When the gear 16 rotates counterclockwise, it drives the two racks 14 meshing with it to move in opposite directions. The two racks 14 then push the two movable blocks 11 outward. The two movable blocks 11 slide outward on the outer wall of the multiple limit rods 9, thereby causing the two locking blocks 5 to disengage from the locking slots 4 and releasing the locking of the card seat 3. At this time, the card seat 3 can be easily separated from the connecting seat 2. The operation is simple and quick.

[0032] After disassembly, loosen knob 17. The movable block 11 will no longer be pushed by the two racks 14. Similarly, it will be reset under the elastic force of spring 12. The movable block 11 will then drive the locking block 5 to extend into the connecting seat 2 for the next installation operation.
