Description

Technical Field

[0001] This application relates to the field of power transmission line technology, and more specifically, to a power transmission line conductor fixing device. Background Technology

[0002] Power transmission lines are widely used in the electromechanical field as conductors for power or signal transmission. However, in most cases, it is necessary to fix the conductors in the running state with wire clamps to prevent the conductors from becoming loose or interfered with by other components, which could lead to short circuits and safety hazards.

[0003] The prior art publication (announcement) number CN212968990U provides a conductor fixing device for transmission lines. In this related technology, the device is bolted to a mounting plate. The wire clamping groove and the arc-shaped groove on the positioning block cooperate to form a channel for the conductor to pass through. As the clamping plate is pressed down, the conductor is clamped. At the same time, after the elastic clamping plate is inserted into the arc-shaped groove, it bends and deforms along the inner wall of the arc-shaped groove, thereby covering both sides of the conductor. The anti-slip spikes on the inner wall of the elastic clamping plate will firmly hold the conductor. It can be seen that this device uses both clamping force and holding force to fix the conductor, ensuring the fixing strength. It is simple and convenient to operate, requiring only the clamping plate to be firmly installed.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following drawbacks: the mounting plate fixing structure requires multiple steps to install on the insulator porcelain column, and the installation and use are not convenient.

[0005] In view of this, we propose a conductor fixing device for power transmission lines. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a conductor fixing device for power transmission lines.

[0007] The transmission line conductor fixing device provided in this application adopts the following technical solution:

[0008] A conductor fixing device for transmission lines includes an insulator magnetic post. A metal elastic buckle is sleeved on the outside of the insulator magnetic post. A semi-ring is fixedly connected to both ends of the metal elastic buckle. A closed ring is rotatably connected to one end of the semi-ring, and a hinge is rotatably connected to the other end of the closed ring. A connecting lug is hinged to the outside of the hinge. A double-headed adjusting screw is fixedly connected between the two connecting lugs. A slider that can be inserted into and limited by the semi-ring is fixedly connected to one side of the closed ring.

[0009] By adopting the above technical solution, the metal elastic buckle is used to expand the aperture through compression deformation, thereby quickly fitting and installing it on the outside of the insulator magnetic post. Under the contraction adjustment of the double-headed adjusting screw, the opened closed loop sleeve and the half loop sleeve are driven to close, which limits the cable placed inside the half loop sleeve, realizing the rapid installation and fixation of the cable. Moreover, the tightening and shortening double-headed adjusting screw can pull and limit the metal elastic buckle, improving the stability of the fitting and installation between the metal elastic buckle and the insulator magnetic post.

[0010] As an optional solution to the technical solution of this application, a rubber pad is fixedly connected to the inner wall of the metal elastic buckle, and the inner wall of the rubber pad is provided with a friction groove with an inclined structure.

[0011] By adopting the above technical solution, the rubber pad can improve the fit between the metal elastic buckle and the insulator magnetic post and prevent the metal elastic buckle from damaging the insulator magnetic post. In addition, the friction groove with an inclined structure on the inner wall of the rubber pad can further improve the tightness of the fit between the rubber pad and the insulator magnetic post.

[0012] As an optional solution to the technical solution of this application, the two semi-rings are arranged in a staggered and symmetrical structure, and a compensating rubber strip is fixedly connected to the inner wall of the semi-ring, the compensating rubber strip being arranged in an arc shape.

[0013] By adopting the above technical solution, the semi-ring sleeve is set in a staggered and symmetrical structure, which makes it easy to ensure that the semi-ring sleeve and the closed ring sleeve form a ring structure for stable connection under the connection and closure limit of the double-headed adjusting screw. The compensation rubber strip can elastically squeeze and limit the placed cable, ensuring the stability of the cable limit.

[0014] As an optional solution to the technical solution in this application, the slot end face of the semi-ring sleeve sidewall is configured as an open structure in the shape of a trumpet.

[0015] By adopting the above technical solution, the slot end face of the semi-ring sleeve is set in an open structure in the shape of a horn, which facilitates the insertion of the slider and achieves precise docking and positioning of the semi-ring sleeve and the closed ring sleeve.

[0016] As an optional solution to the technical solution of this application, the slider is configured in an arc shape, and the axis of the slider and the axis of the closed loop are located on the same axis line.

[0017] By adopting the above technical solution, the slider axis and the closed-loop sleeve axis, which are set in an arc shape, are located on the same axis line, which makes it easier to ensure the precise insertion and positioning of the half-ring sleeve and the closed-loop sleeve.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application utilizes the compression deformation of a metal elastic buckle to expand the aperture, thereby enabling rapid installation on the outside of the insulator magnetic post. Under the contraction adjustment of the double-headed adjusting screw, the opened closed-loop sleeve and the semi-loop sleeve are driven to close, thereby limiting the connection of the cable placed inside the semi-loop sleeve, achieving rapid installation and fixation of the cable. Furthermore, the tightening and shortening of the double-headed adjusting screw can pull and limit the metal elastic buckle, improving the stability of the connection between the metal elastic buckle and the insulator magnetic post.

[0020] 2. This application utilizes a rubber pad to improve the fit between the metal elastic buckle and the insulator magnetic post, and to prevent the metal elastic buckle from damaging the insulator magnetic post. Furthermore, the rubber pad has friction grooves with an inclined structure on its inner wall, which can further improve the tightness of the fit between the rubber pad and the insulator magnetic post.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1-3 The transmission line conductor fixing device described in this application includes an insulator magnetic column 1. A metal elastic buckle 2 is sleeved on the outside of the insulator magnetic column 1. Half ring sleeves 3 are fixedly connected to both ends of the metal elastic buckle 2. A closed ring sleeve 4 is rotatably connected to one end of the half ring sleeve 3. A hinge seat 5 is rotatably connected to the other end of the closed ring sleeve 4. A connecting ear 6 is hinged on the outside of the hinge seat 5. A double-headed adjusting screw 7 is fixedly connected between the two connecting ears 6. A slider 8 that can be inserted into and limited by the half ring sleeve 3 is fixedly connected to one side of the closed ring sleeve 4.

[0027] This power transmission line conductor fixing device utilizes the compression deformation of the metal elastic buckle 2 to expand the aperture, thereby quickly fitting it onto the outside of the insulator magnetic post 1. Under the contraction adjustment of the double-headed adjusting screw 7, the opened closed-loop sleeve 4 and the semi-loop sleeve 3 are driven to close, limiting the cable placed inside the semi-loop sleeve 3, thus achieving rapid installation and fixing of the cable. Furthermore, the tightened and shortened double-headed adjusting screw 7 can pull and limit the metal elastic buckle 2, improving the stability of the fitting installation between the metal elastic buckle 2 and the insulator magnetic post 1.

[0028] Reference Figure 3 and Figure 1 In the transmission line conductor fixing device described in this application embodiment, a rubber pad 21 is fixedly connected to the inner wall of the metal elastic buckle 2, and a friction groove 22 with an inclined structure is opened on the inner wall of the rubber pad 21.

[0029] The conductor fixing device for this transmission line can improve the fit between the metal elastic buckle 2 and the insulator magnetic post 1 by using the rubber pad 21, and prevent the metal elastic buckle 2 from damaging the insulator magnetic post 1. Furthermore, the friction groove 22 with an inclined structure is opened on the inner wall of the rubber pad 21, which can further improve the tightness of the fit between the rubber pad 21 and the insulator magnetic post 1.

[0030] Reference Figure 3 and Figure 1 In the transmission line conductor fixing device described in this application embodiment, the two half rings 3 are arranged in a staggered and symmetrical structure, and a compensating rubber strip 31 is fixedly connected to the inner wall of the half ring 3. The compensating rubber strip 31 is arranged in an arc-shaped structure, and the slot end face opened on the side wall of the half ring 3 is arranged in a trumpet-shaped open structure.

[0031] The conductor fixing device for this transmission line utilizes a staggered and symmetrical semi-ring sleeve 3 to ensure a stable connection between the semi-ring sleeve 3 and the closed-loop sleeve 4 under the closed limit of the double-headed adjusting screw 7. The compensating rubber strip 31 can elastically compress and limit the placed cable to ensure the stability of the cable limit. The slot end face of the side wall of the semi-ring sleeve 3 is designed with a funnel-shaped open structure to facilitate the insertion of the slider 8, achieving precise docking and limit of the semi-ring sleeve 3 and the closed-loop sleeve 4.

[0032] Reference Figure 2 and Figure 3 In the transmission line conductor fixing device described in this application embodiment, the slider 8 is arranged in an arc shape, and the axis of the slider 8 and the axis of the closed loop sleeve 4 are located on the same axis line.

[0033] The conductor fixing device for this transmission line utilizes the fact that the axis of the slider 8, which is set in an arc shape, is on the same axis as the axis of the closed-loop sleeve 4, which facilitates the precise insertion and limiting of the semi-ring sleeve 3 and the closed-loop sleeve 4.

[0034] Working principle: When using this device to quickly install the cable and the insulator magnetic post 1, the operator manually squeezes the semi-ring sleeve 3 to bring them closer together. The squeezed semi-ring sleeve 3 causes the metal elastic buckle 2 to deform and expand its inner diameter.

[0035] Next, the metal elastic buckle 2 with an enlarged inner diameter is put on the recess of the insulator magnetic post 1, the pressed half ring 3 is released, the metal elastic buckle 2 is reset, and it is tightly attached to the outside of the insulator magnetic post 1 on the left and right sides of the rubber pad 21 for limiting.

[0036] When the metal elastic buckle 2 deforms, the closed ring sleeve 4, which is rotatably connected inside the semi-ring sleeve 3, rotates and adjusts with the semi-ring sleeve 3, without changing the connection relationship between the two closed ring sleeves 4 and the double-headed adjusting screw 7.

[0037] Finally, secure the cable inside the two half-ring sleeves 3, and adjust the double-headed adjusting screw 7 to drive the closed ring sleeve 4 to connect and close with the half-ring sleeve 3 to fix it in place.
