Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a wire threading assistant for electrical engineering construction. Background Art
[0002] During the electrical automation construction process, since the wiring conduit is buried in the wall, the wires cannot be seen directly by the operator and cannot be threaded quickly when the wires are inserted through the conduit through the wiring box. At this time, the operator generally uses an assistant to speed up the threading. When the existing threading assistant is placed in the corresponding wiring box for auxiliary threading, the assistant has a relatively simple structure and cannot be quickly adjusted for wiring boxes of different sizes.
[0003] In order to solve the above problems, a Chinese utility model patent with application number CN202222281343.2 discloses a threading aid, including an installation frame, connecting frames are fixedly installed on the surface of both ends of the side of the installation frame, a hollow frame is fixedly installed on the top surface of the outer side of each connecting frame, a bidirectional screw rod is rotatably installed through the inner sides of each two groups of hollow frames, and a movable sleeve is movably connected to the outer side surfaces of each bidirectional screw rod at both ends.
[0004] The above scheme drives the synchronous movement of the clamping frame through the transmission of the bidirectional screw rod and the transmission rod to adjust the spacing to fit the inner walls of wiring boxes of different sizes. However, during the wiring process, it is not only necessary to do it in the wiring box, but may also be used for wiring in distribution boxes and switch boxes. Due to the large difference in size between wiring boxes and distribution boxes, a single adjustment form cannot adapt to different application environments, resulting in limited use of the auxiliary device and certain limitations. Utility Model Content
[0005] In view of the deficiencies existing in the prior art, the utility model provides an electrical engineering construction threading aid, which solves the problem of limited application scenarios of the aid in the prior art.
[0006] In order to solve the above problems, the utility model provides the following solutions:
[0007] An electrical engineering construction threading aid, comprising:
[0008] A support frame, the support frame comprising two support rods, with a roller shaft rotatably arranged between the two support rods;
[0009] One end of the two support rods is provided with a threaded hole and both are threadedly connected with an adjustment rod, and the two adjustment rods are connected with a limiting member;
[0010] The locking members are provided with two, and the two locking members are respectively arranged on the two support rods and each includes a first locking block and a second locking block. The two first locking blocks are fixedly mounted on the corresponding support rods, and the two second locking blocks are slidably connected to the corresponding support rods through elastic members, and a driving member is connected between the two second locking blocks to enable them to move synchronously.
[0011] The technical principle of the utility model is:
[0012] When a single-hole or multi-hole wire box is required to be threaded, the size of the wire box is small, so the clamping piece can be used to contact the inner wall of the wire box. Pressing the driving piece causes the two second clamps to move simultaneously, and the distance between the first clamp and the second clamp is reduced. At this time, the elastic piece is compressed, and the first clamp and the second clamp are extended into the wire box. After the pressing is canceled, the elastic piece rebounds and the first clamp and the second clamp are respectively against the upper and lower inner walls of the wire box. Due to the action of the elastic piece, the friction between the first clamp and the second clamp and the inner wall of the wire box increases, and the auxiliary device is not easy to slide out of the wire box.
[0013] When the switch box and the distribution box need to be threaded, due to the large size of the switch box and the distribution box, a retractable adjustment rod is required to contact the inner wall of the switch box or the distribution box. At this time, the adjustment rod is adjusted to the corresponding position and abutted against the top of the switch box or the distribution box, driving the limiter to limit the position, and the adjustment rod is fixed on the support rod to adapt to the size of the switch box or the distribution box.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. By setting a positioning piece and an adjusting rod and combining two adjustment methods, the auxiliary device can be applied to different application scenarios and can adapt to more sizes for threading work, thereby increasing the practicality of the auxiliary device.
[0016] 2. The auxiliary device is simple to operate and easy to use; it can not only improve the subsequent threading efficiency but also adapt well to different scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides an electrical engineering construction threading assistant, comprising:
[0023] A support frame, the support frame comprises two support rods 1, and a roller shaft 2 is rotatably arranged between the two support rods 1;
[0024] One end of the two support rods 1 is provided with a threaded hole 3 and both are threadedly connected with an adjusting rod 4, and the two adjusting rods 4 are connected to a limiting member;
[0025] The locking members are provided with two, which are respectively arranged on the two support rods 1 and each includes a first locking block 5 and a second locking block 6. The two first locking blocks 5 are fixedly mounted on the corresponding support rods 1, and the two second locking blocks 6 are both slidably connected to the corresponding support rods 1 through elastic members, and a driving member is connected between the two second locking blocks 6 to enable them to move synchronously.
[0026] In the prior art, during the wiring process, it is not only necessary to carry out the work in the wiring box, but may also be used to thread the wires in the distribution box and the switch box. Due to the large difference in size between the wiring box and the distribution box, a single adjustment form cannot adapt to different application environments, resulting in limited use of the auxiliary device and certain limitations.
[0027] In order to solve the above problems, this embodiment provides two adjustment methods to adapt to different application scenarios.
[0028] Specifically, the detailed working process of this embodiment is as follows:
[0029] When a single-hole or multi-hole wire box is required to be threaded, the size of the wire box is small, so the clamping piece can be used to contact the inner wall of the wire box. Pressing the driving piece causes the two second clamps 6 to move simultaneously, and the distance between the first clamp 5 and the second clamp 6 is reduced. At this time, the elastic piece is compressed, and the first clamp 5 and the second clamp 6 are extended into the wire box. After the pressing is canceled, the elastic piece rebounds and the first clamp 5 and the second clamp 6 are respectively against the upper and lower inner walls of the wire box. Due to the action of the elastic piece, the friction between the first clamp 5 and the second clamp 6 and the inner wall of the wire box increases, and the auxiliary device is not easy to slide out of the wire box.
[0030] When the switch box and the distribution box need to be threaded, the retractable adjustment rod 4 needs to be used to contact the inner wall of the switch box or the distribution box due to the large size of the switch box and the distribution box. At this time, the adjustment rod 4 is adjusted to the corresponding position and then abutted against the top of the switch box or the distribution box, driving the limiter to limit the position, and the adjustment rod 4 is fixed on the support rod 1 to adapt to the size of the switch box or the distribution box.
[0031] Furthermore, the two support rods 1 are each provided with a sliding cavity 7 and a through hole connected to the sliding cavity 7 and for the second clamping block 6 to pass through, and the elastic member includes a spring 8 arranged between a side wall of the sliding cavity 7 and the second clamping block 6 .
[0032] In this embodiment, the second clamping block 6 slides in the sliding cavity 7 , and the provision of the through hole and the sliding cavity 7 facilitates the installation of the spring 8 .
[0033] Specifically, the second card block 6 slides in the sliding cavity 7, and when the spring 8 is pressed, the distance between the first card block 5 and the second card block 6 changes to facilitate the first card block 5 and the second card block 6 to be inserted into the wire box; then the rebound of the spring 8 makes the first card block 5 and the second card block 6 clamped to the inner wall of the wire box and not easy to fall off.
[0034] Further, the driving member is a pressing handle 10. By providing the pressing handle 10, the pressing handle 10 can simultaneously drive the two second clamping blocks 6 to move together, which is convenient for the operator to operate to clamp the auxiliary device into the wire box.
[0035] Since the above embodiment uses the elastic force of the spring 8 to maintain the first clamp 5 and the second clamp 6 against the inner wall of the wire box, if the operator uses too much force or brute force, the auxiliary device is easily dragged out of the wire box. In order to reduce the risk that the auxiliary device may slip out of the wire box, further, the tops of the two first clamps 5 are provided with anti-slip serrations 9. By providing the anti-slip serrations 9, the friction between the first clamp 5 and the inner wall of the wire box is increased, so that the auxiliary device is not easy to fall out, ensuring the normal operation of the auxiliary device.
[0036] Furthermore, the adjusting rod 4 is a threaded rod, and the limiting member is a nut 11 threadably connected to the threaded rod and used to abut against the support rod 1; in addition, one side of the second clamping block 6 is connected to a telescopic rod 12 located in the sliding cavity 7, and the telescopic rod 12 extends out of the end of the support rod 1 away from the threaded rod.
[0037] Specifically, the working process of this embodiment is: first rotate the nut 11 and adjust its position on the threaded rod, then extend one end of the threaded rod into the threaded hole 3 until it abuts against the nut 11 and tightens it again, then press the hand lever 10, the second clamping block 6 moves to drive the telescopic rod 12 to move, so that the staff can put the auxiliary device into the switch box or distribution box, then the spring 8 rebounds, the telescopic rod 12 extends out of the support rod 1, and the threaded rod and the telescopic rod 12 can be well abutted against the inner wall of the switch box or distribution box to achieve fixation.
[0038] like Figure 1As shown, since impurities may be contaminated during the process of carrying and threading the wire, affecting the subsequent use and winding, the utility model also proposes another embodiment. The main difference between this embodiment and the above embodiment is that a dust removal component located below the roller 2 is also provided between the two support rods 1, and the dust removal component includes two rotating shafts 13 rotatably arranged between the two support rods 1 and distributed up and down, and the two rotating shafts 13 are arranged in a coordinated manner and the outer surfaces are connected to wet sponge layers 14.
[0039] In this embodiment, the two rotating shafts 13 are installed on the support rod 1 through bearings; when in use, the wire passes through the two rotating shafts 13, and during the threading process, the wet sponge layer 14 can wipe off the impurities on the outer wall of the wire to achieve a cleaning effect.
[0040] Furthermore, an adhesive layer 15 is provided between the rotating shaft 13 and the wet sponge layer 14 .
[0041] By setting the adhesive layer 15, the rotating shaft 13 and the wet sponge layer 14 can be bonded together. The adhesive layer 15 in this embodiment is similar to the function of a double-sided tape; when replacement is required, the wet sponge layer 14 and the adhesive layer 15 can be torn off together at any time, and then a new wet sponge layer 14 can be re-bonded.
[0042] The specific working process of the utility model is:
[0043] When a single-hole or multi-hole wire box is required to be threaded, the size of the wire box is small, so the clamping piece can be used to contact the inner wall of the wire box. The operator uses the pressing hand lever 10 to make the two second clamping blocks 6 slide in the sliding cavity 7. At this time, the spring 8 is pressed, and the distance between the first clamping block 5 and the second clamping block 6 becomes smaller to facilitate the first clamping block 5 and the second clamping block 6 to be clamped into the wire box; then the rebound of the spring 8 makes the first clamping block 5 and the second clamping block 6 clamped to the inner wall of the wire box and not easy to fall off. The top of the first clamping block 5 is provided with anti-slip serrations 9, so that the auxiliary device is not easy to fall out.
[0044] When the switch box and the distribution box need to be threaded, due to the large size of the switch box and the distribution box, the retractable adjustment rod 4 is required to contact the inner wall of the switch box or the distribution box. First, rotate the nut 11 and adjust its position on the threaded rod, then extend one end of the threaded rod into the threaded hole 3 until it contacts the nut 11 and tighten it again, then press the hand lever 10, the second block 6 moves to drive the telescopic rod 12 to move, so that the staff can put the auxiliary device into the switch box or the distribution box, then the spring 8 rebounds, the telescopic rod 12 extends out of the support rod 1, and the threaded rod and the telescopic rod 12 can be well contacted with the inner wall of the switch box or the distribution box to achieve fixation.
[0045] In addition, when the electric wire is passed through between the two rotating shafts 13, during the threading process, the wet sponge layer 14 can wipe away impurities on the outer wall of the electric wire to achieve a cleaning effect.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
