Description

Technical Field

[0001] The utility model relates to the technical field of engineering electrical pre-buried pipelines, in particular to an engineering electrical pre-buried pipeline device. Background Art

[0002] Aluminum alloy junction boxes, joint pipes, sleeves, aluminum alloy pipes and other parts are often used in engineering electrical pre-buried pipelines. When pre-buried pipelines, the joint pipe is screwed and installed on the junction box, the sleeve is inserted at one end of the joint pipe, and the aluminum alloy pipe is inserted at the end of the sleeve away from the joint pipe. Then, the sharp nails on the crimping pliers are inserted between the sleeve and the joint pipe and between the sleeve and the aluminum alloy pipe. The sharp nails press holes between the sleeve and the joint pipe and between the sleeve and the aluminum alloy pipe, and the holes are used to connect and fix different types of pipelines;

[0003] When using the spikes on the crimping pliers to crimp the sleeve, the outer side of the sleeve is a smooth curved surface, which is not conducive to the spikes to limit the contact with the outer side of the sleeve in the initial state, and it is easy to cause the holes crimped on the sleeve later to be skewed, affecting the strength of the connection and fixation between the sleeve and the joint pipe, and the sleeve and the aluminum alloy pipe. In addition, when the stud on the crimping pliers is rotated to adjust the position of the sleeve to limit the position of the sleeve, the stud lacks a structure to assist in screwing the stud, which is not conducive to the user to easily screw the stud to clamp the sleeve. Utility Model Content

[0004] The utility model aims to provide an engineering electrical pre-buried pipeline device to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The electrical pre-buried pipeline device for an engineering project comprises a junction box, one side of the junction box is screwed and connected with a joint pipe, one end of the joint pipe facing away from the junction box is sleeved with a sleeve, and the end of the sleeve facing away from the joint pipe is plugged with an aluminum alloy pipe, and a crimping pliers is sleeved on the outside of the sleeve, and the crimping pliers comprises a handle one, and the top of the handle one is transmission-connected with a handle two, and a traction mechanism for accommodating the handle one and the handle two is arranged between the handle one and the handle two, an arc block is fixed at one end of the handle one, and a plug rod is slidably plugged into the position of the arc block near the end of the handle one, and two studs are screwed and connected on the outside of the arc block, a columnar chamber is opened on the inner top of the stud, a rotating seat is slidably connected to the inside of the columnar chamber, and a rotating rod is rotatably connected to the top of the rotating seat, a sharp nail is fixed to the bottom end of the stud and the top end of the plug rod, and a plurality of limit rings for limiting the position of the sharp nail are evenly fixed on the outside of the two ends of the sleeve.

[0007] Furthermore, two nuts which are screwed together with the studs at corresponding positions are fixed on the outer side of the arc block, and a limit block which is slidably engaged with the columnar chamber is fixed on the bottom of the rotating seat.

[0008] Furthermore, the diameter of the rotating rod is smaller than the diameter of the columnar chamber, and a loop rope is fixed to one end of the rotating rod.

[0009] Furthermore, a rubber block is fixed to one end of one of the studs, and a rubber sleeve is sleeved and fixed to one end of the first handle and the second handle.

[0010] Furthermore, a conical hole is formed at a center of the sleeve close to the limiting ring, and a middle portion of the sleeve is recessed toward the inside of the sleeve.

[0011] Furthermore, the traction mechanism comprises a connecting rod rotatably connected to the second handle, one end of the connecting rod is slidably connected to a sliding column, and one end of the sliding column is fixed with a second loop rope.

[0012] Furthermore, a sliding groove is provided on the outer side of the sliding column, and a sliding block is fixed inside the connecting rod and is slidably engaged with the sliding groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By evenly fixing multiple limiting rings on the outside of the casing, a conical hole is opened at the middle position of the outside of the casing near the limiting ring, and the sharp nails of the crimping pliers can be pre-inserted into the conical hole, so that the sharp nails can be stably fixed on the outer curved surface of the casing, which is convenient for pressing the handle 2 later so that the two sharp nails can be accurately inserted between the casing and the joint pipe or between the casing and the aluminum alloy pipe, ensuring the strength of the connection and fixing position between the casing and the joint pipe, and the casing and the aluminum alloy pipe. The inner ring diameter of the limiting ring is smaller than the diameter of the stud, which can limit the depth of the conical sharp nail inserted into the pipe, and effectively prevent the sharp nail from being inserted too deeply into the casing.

[0015] 2. Pull the rope to slide the rotating rod out from the inside of the stud, and then rotate the rotating rod on the rotating seat by 90 degrees to make the rotating rod perpendicular to the stud. The user can conveniently screw the stud through the stud. When the stud needs to be rotated, the user can rotate the rotating rod to a coaxial state with the stud, and then slide the rotating rod into the columnar chamber of the stud to store the rotating rod for assisting the rotation of the stud.

[0016] 3. By rotating the connecting rod, the sliding column is moved to the position above the socket of handle one, and then the sliding column is inserted into the socket, so that handle one and handle two are connected and fixed together through the connecting rod, eliminating the need for traditional crimping pliers to use ropes to tie the two handles together when not in use to prevent the handles from automatically unfolding, which is beneficial to improving the firmness of the connection between handle one and handle two.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1-6In the embodiment of the utility model, the engineering electrical pre-buried pipeline device, the junction box 100, one side of the junction box 100 is screwed and connected with a joint pipe 110, the end of the joint pipe 110 away from the junction box 100 is sleeved with a sleeve 200, the end of the sleeve 200 away from the joint pipe 110 is plugged with an aluminum alloy pipe 300, the outer side of the sleeve 200 is sleeved with a crimping pliers 400, the crimping pliers 400 include a handle 410, the top of the handle 410 is transmission-connected with a handle 2 420, and a traction mechanism 4 for accommodating the handle 410 and the handle 2 420 is provided between the handle 410 and the handle 2 420. 30. An arc block 440 is fixed at one end of the handle 410, and a plug rod 441 is slidably inserted into the arc block 440 near the end of the handle 410. Two studs 500 are screwed together on the outer side of the arc block 440. A columnar chamber 510 is opened on the inner top of the stud 500. A rotating seat 520 is slidably connected inside the columnar chamber 510. A rotating rod 521 is rotatably connected to the top of the rotating seat 520. A sharp nail 530 is fixed to the bottom end of the stud 500 and the top end of the plug rod 441. A plurality of limit rings 210 for limiting the position of the sharp nail 530 are evenly fixed to the outer sides of both ends of the sleeve 200.

[0026] Specifically, tapered holes 220 are evenly opened on the outer sides of both ends of the sleeve 200, and a limiting ring 210 is fixed on the outer sides of the tapered holes 220. When the crimping pliers 400 are used to crimp the sleeve 200 and the joint pipe 110 or the sleeve 200 and the aluminum alloy pipe 300, the tapered holes 220 can enable the sharp nails 530 on the crimping pliers 400 to be inserted into the tapered holes 220, preventing the sharp nails 530 from sliding and shifting on the outer side of the sleeve 200, which is conducive to the precise insertion of the sharp nails 530 into the sleeve 200. The limiting ring 210 limits the depth of the sharp nails 530 inserted into the sleeve 200, preventing the sharp nails 530 from being inserted too deeply into the sleeve 200 and damaging the pipeline.

[0027] like Figure 4 and Figure 5 As shown, in this embodiment, two nuts 442 which are respectively screwed and connected with the corresponding studs 500 are fixed to the outer side of the arc block 440, and a limit block 522 which is slidably engaged with the columnar chamber 510 is fixed to the bottom of the rotating seat 520.

[0028] In this embodiment, the stud 500 is rotated so that the stud 500 can be screwed and moved inside the nut 442 toward the sleeve 200, so that the rubber block on the stud 500 can abut the sleeve 200, the spike 530 of the stud 500 can be inserted into the sleeve 200, and the limit block 522 prevents the rotating seat 520 from detaching from the columnar chamber 510, so that the rotating rod 521 will not detach from the stud 500.

[0029] like Figure 4 and Figure 5As shown, in this embodiment, the diameter of the rotating rod 521 is smaller than the diameter of the columnar chamber 510, and a loop rope 1 is fixed to one end of the rotating rod 521. The loop rope 1 facilitates pulling the rotating rod 521 out from the columnar chamber 510 of the stud 500, and the rotating rod 521 can also be stored inside the columnar chamber 510.

[0030] like Figure 4 and Figure 6 As shown, in this embodiment, a rubber block is fixed to one end of a stud 500, and a rubber sleeve is fixed to one end of handle 1 410 and handle 2 420. The rubber block increases the friction between the stud 500 and the sleeve 200, and the rubber sleeve enables the user to hold handle 1 410 and handle 2 420 tightly.

[0031] like Figure 3 As shown, in this embodiment, a conical hole 220 is opened at the center of the sleeve 200 near the limiting ring 210, and the middle of the sleeve 200 is recessed toward the inside of the sleeve 200. The conical hole 220 enables the spike 530 on the crimping pliers 400 to be accurately inserted into the inside of the sleeve 200. The middle of the sleeve 200 is recessed toward the inside of the sleeve 200 so that the two ends of the sleeve 200 can be inserted into different types of pipes of appropriate depth.

[0032] In a specific implementation, the joint pipe 110 is screwed and installed on the outer side of the junction box 100, and then the sleeve 200 is sleeved on the joint pipe 110, and then the aluminum alloy pipe 300 is inserted into the sleeve 200, and the arc block 440 of the crimping pliers 400 is sleeved on the outer side of the sleeve 200. Here, the crimping pliers 400 are used as an example to crimp and fix the sleeve 200 and the joint pipe 110 to illustrate the working principle, and the two studs 500 are rotated so that the rubber block at the end of one stud 500 abuts against the sleeve 200, and the spike 530 at the end of the other stud 500 is inserted into the tapered hole 220 of the sleeve 200, and then the handle is pressed in the direction of handle 1 410. The second handle 420 causes the insertion rod 441 on the arc block 440 to move with the spike 530 toward the sleeve 200, so that the two oppositely arranged spikes 530 insert a hole between the sleeve 200 and the joint pipe 110, so that the sleeve 200 and the joint pipe 110 are connected and fixed. Then, the second handle 420 is released to cause the insertion rod 441 with the spike 530 to detach from the sleeve 200, so that the crimping pliers 400 can be changed to another position. Similarly, the holes 411 at other positions of the sleeve 200 and the joint pipe 110 can be inserted to fix the sleeve 200 and the joint pipe 110. The crimping pliers 400 are a commonly used tool in the prior art, and the specific working principle will not be elaborated on.

[0033] Embodiment 2 is based on Embodiment 1, in order to enable the handle 1 410 and the handle 2 420 on the crimping pliers 400 to be stored together when not in use.

[0034] like Figure 2 and Figure 6As shown, in this embodiment, the traction mechanism 430 includes a connecting rod 431 rotatably connected to the handle 2 420, one end of the connecting rod 431 is slidably connected to a sliding column 432, one end of the sliding column 432 is fixed with a loop rope 2, a sliding groove 4321 is provided on the outer side of the sliding column 432, and a sliding block slidably engaged with the sliding groove 4321 is fixed inside the connecting rod 431.

[0035] For details, refer to the instruction manual in the initial state. Figure 2 The sliding column 432 is inserted into the handle 1 410, and the connecting rod 431 connects and fixes the handle 1 410 and the handle 2 420 together. When the crimping pliers 400 are needed to crimp the sleeve 200 with different types of pipes, refer to the instructions. Figure 6 , pull out the sliding column 432 upwards through the rope second, so that the sliding column 432 is separated from the handle one 410, and the handle one 410 is separated from the handle two 420, so that the user can press the handle two 420 to make the insertion rod 441 on the crimping pliers 400 with the sharp nail 530 plug into the sleeve 200, wherein the crimping pliers 400 realizes the insertion of the insertion rod 441 into the crimping sleeve 200 by pressing the handle, which is the prior art, and the specific working principle of moving the insertion rod 441 by pressing the handle is not elaborated here, and the sliding groove 4321 on the outer side of the sliding column 432 slides on the slider to prevent the sliding column 432 from being separated from the connecting rod 431.
