Description

Technical Field

[0001] This utility model relates to the field of power engineering and electromechanical installation technology, specifically to an electrical line installation hanger. Background Technology

[0002] Electrical wiring hangers are engineering devices used to support and fix electrical wiring. They are widely used in industries, construction, and other fields, and are core components that ensure the stability and electrical safety of cable trays containing electrical wiring.

[0003] However, when existing electrical wiring hangers are connected to cable trays, the length of the crossarm on the hanger is larger than the width of the cable tray, and the center of the bottom of the cable tray needs to be aligned with the center of the hanger crossarm for fixation. This makes the adjustment process of the cable tray and crossarm cumbersome and time-consuming, which is not conducive to the installation and fixation of the electrical cable tray on the hanger crossarm. In addition, the support direction of the existing hangers and electrical cable trays is limited to the horizontal direction, that is, the crossarm of the hanger only contacts a small part of the horizontal area of ​​the bottom of the electrical cable tray. When the spacing of the hangers is large, the electrical cable tray is prone to sagging and deformation. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical wiring installation hanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical wiring installation hanger, including a crossarm, with a longitudinal arm fixedly connected to the middle of both the front and back sides of the crossarm. The longitudinal arm has a sliding plate inside, and second slide rails are provided on both side walls of the sliding plate. A second fastening screw is threaded through one side wall of the longitudinal arm. Hanging rods are provided on both sides of the crossarm, with external threads in the middle of each hanging rod. A rotating plate is fitted onto the outer side of the external threads, and a push plate is provided inside the rotating plate. A telescopic spring is provided on one side of the push plate. First slide rails are provided on both sides of the top of the crossarm, and a sliding frame is slidably connected to the top of each first slide rail. A clamping plate is fixedly connected to one side of the top of the sliding frame, and a gasket is provided on one side wall of the push plate.

[0006] Preferably, the bottom end of the boom is connected to the crossbeam through a fixed screw, and a locking nut is threaded onto the bottom end of the screw. The boom is fixedly connected to the crossbeam through the locking nut.

[0007] Preferably, a first fastening screw is threaded through the middle of the top of the slide frame, and the first fastening screw is slidably connected to the first slide rail.

[0008] Preferably, a locking nut is fitted onto the bottom thread of the first fastening screw, and the slide frame is slidably connected to the crossbeam via the first fastening screw.

[0009] Preferably, the second fastening screw is slidably connected to the slide plate via the second slide rail, and a locking nut is fitted onto the movable thread at the end of the second fastening screw. The slide plate is slidably connected to the longitudinal support via the second fastening screw.

[0010] Preferably, the rotating plate has a cavity inside, one end of the telescopic spring is fixedly connected to one side wall of the push plate, and the other end of the telescopic spring is fixedly connected to the inner wall of the cavity.

[0011] Preferably, the push plate is slidably connected to the rotating plate via a telescopic spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The electrical wiring installation hanger, through the external thread, rotating plate, push plate and telescopic spring, when the wire trough needs to be connected to the hanger, the two side walls of the wire trough will be clamped by the push plate pushed out by the deformation of the telescopic spring. Since the push plate and telescopic spring are symmetrically arranged on both sides of the hanger, and when the center of the bottom of the wire trough coincides with the center of the crossarm, the force generated by the deformation of the telescopic spring on both sides of the hanger is the same, so that the wire trough can maintain a stable state at the center of the crossarm, which is conducive to fixing the wire trough to the crossarm with clamps later.

[0013] 2. The electrical wiring installation hanger, through the setting of longitudinal arms, sliding plates, second slide rails and second fastening screws, enables the crossarm at the bottom of the hanger to not only provide horizontal support to the bottom of the cable tray, but also to provide horizontal longitudinal support to the bottom of the cable tray. This increases the support area of ​​the crossarm on the cable tray, compensating for the insufficiency of cable trays on large-spacing hangers that are prone to sagging, thereby reducing the probability of cable trays on large-spacing hangers deforming due to sagging.

[0019] like Figures 1 to 4As shown, the electrical wiring installation hanger in this embodiment includes a crossarm 6. A longitudinal arm 14 is fixedly connected to the middle of the front and back of the crossarm 6. A sliding plate 11 is provided inside the longitudinal arm 14. A second slide rail 12 is provided on both sides of the sliding plate 11. A second fastening screw 13 is threaded through one side of the longitudinal arm 14. A hanging rod 1 is provided on both sides of the crossarm 6. An external thread 2 is provided in the middle of the hanging rod 1. A rotating plate 3 is fitted on the outer side of the external thread 2. A push plate 4 is provided inside the rotating plate 3. A telescopic spring 15 is provided on one side of the push plate 4. A first slide rail 9 is provided on both sides of the top of the crossarm 6. A sliding frame 8 is slidably connected to the top of the first slide rail 9. A clamping plate 7 is fixedly connected to one side of the top of the sliding frame 8. A gasket 5 is provided on one side of the push plate 4.

[0020] Specifically, the original lengths of the two longitudinal supports 14 are fixed, but the subsequent length of the longitudinal supports 14 can be adjusted by extending and shortening the sliding plate 11, thereby improving the flexibility of the longitudinal supports 14 during support use. The function of the second slide rail 12 is to allow the sliding plate 11 to slide out smoothly and stably along the inside of the longitudinal support 14. The function of the second fastening screw 13 and the locking nut 17 is to fix the sliding plate 11 on the longitudinal support 14 after it has slid out. The function of the hanger 1 is to fix the crossarm 6 in a suitable position. The rotating plate 3 is composed of a cylinder with internal threads and a plate, so that the rotating plate 3 can be adjusted by rotating along the external threads 2 to achieve the vertical position of the rotating plate 3 on the hanger 1. The position adjustment improves the flexibility of the rotating plate 3 during use. The push plate 4 can be pushed out from one side of the rotating plate 3 under the action of the telescopic spring 15, so that the outer wall of the electrical wiring trough placed on the crossarm 6 can be clamped, which facilitates the subsequent locking and fixing of the wiring trough to the crossarm 6 by the clamping plate 7. The function of the first slide rail 9 is to allow the first fastening screw 10 to pass through the crossarm 6, and at the same time, it is convenient for the slide frame 8 to be fixed by the first fastening screw 10 and the locking nut 17 after the position is adjusted, thereby fixing the position of the clamping plate 7 on the crossarm 6, and thus achieving the clamping and fixing of the electrical wiring trough on the crossarm 6 by the clamping plate 7. The gasket 5 is made of rubber with a rough surface, which can enhance the clamping of the clamping plate 7 on the two side walls of the electrical wiring trough.

[0021] Furthermore, the bottom end of the lifting rod 1 is connected to the crossbeam 6 through a fixed screw. The bottom end of the screw is fitted with a locking nut 17. The lifting rod 1 is fixedly connected to the crossbeam 6 through the locking nut 17, so that the lifting rod 1 can be flexibly disassembled and assembled with the crossbeam 6, thereby facilitating the movement and transportation of this hanger.

[0022] Furthermore, a first fastening screw 10 is threaded through the middle of the top of the slide frame 8. The first fastening screw 10 is slidably connected to the first slide rail 9. The first fastening screw 10 can limit the sliding of the slide frame 8 along the crossarm 6, so that the slide frame 8 can slide stably along the crossarm 6.

[0023] Furthermore, a locking nut 17 is provided on the bottom thread of the first fastening screw 10. The slide frame 8 is slidably connected to the crossbeam 6 through the first fastening screw 10. The function of the locking nut 17 is to lock the bottom of the first fastening screw 10, thereby facilitating the first fastening screw 10 to fix the slide frame 8 on the crossbeam 6.

[0024] Furthermore, the second fastening screw 13 is slidably connected to the slide plate 11 through the second slide rail 12, and the end of the second fastening screw 13 is fitted with a locking nut 17. The slide plate 11 is slidably connected to the longitudinal support 14 through the second fastening screw 13. The slide plate 11 can extend or retract along the longitudinal support 14, so that the length of the longitudinal support 14 can be flexibly adjusted according to the distance between adjacent hangers, thereby ensuring the support effect of the longitudinal support 14 on the electrical cable tray.

[0025] Furthermore, the rotating plate 3 has a cavity 16 inside. One end of the telescopic spring 15 is fixedly connected to one side wall of the push plate 4, and the other end of the telescopic spring 15 is fixedly connected to the inner wall of the cavity 16. The telescopic spring 15 can cause the push plate 4 to slide in or out along the rotating plate 3 by deformation, thereby temporarily clamping the electrical wire trough on the crossarm 6 so that the wire trough can be fixed on the crossarm 6 by the clamping plate 7 later.

[0026] Furthermore, the push plate 4 is slidably connected to the rotating plate 3 via the telescopic spring 15. The push plate 4 can freely extend and retract along the rotating plate 3 under the action of the telescopic spring 15, which facilitates the push plate 4 to temporarily clamp the grooves of different widths, thereby improving the flexibility of the push plate 4 during use.

[0027] The usage method of this embodiment is as follows: When using this electrical wiring installation bracket, the bracket needs to be installed in the set position first. Then, according to the required fixed wire trough length, the slide plate 11 is pulled out along the longitudinal arm 14, so that the slide plate 11 slides along the second locking screw through the second slide rail 12. After the slide plate 11 is pulled out to the appropriate length, the locking nut 17 is tightened to the end of the second locking screw, so that the slide plate 11 is fixed on the longitudinal arm 14 by the second locking screw. Then, the electrical wiring trough is placed on the crossarm 6 of the bracket, so that the bottom of the wire trough is in contact with the top of the longitudinal arm 14, and then it can be rotated. Rotating plate 3 allows it to rotate along external thread 2, enabling vertical adjustment along hanger 1 until push plate 4 on rotating plate 3, pushed by telescopic spring 15, fits against the side wall of electrical cable tray. The two side walls of electrical cable tray are then clamped onto crossarm 6 by push plate 4. Next, slide frame 8 can be pushed to slide along first slide rail 9, causing clamping plate 7 to slide along crossarm 6 towards the side wall of cable tray until the pad 5 on clamping plate 7 clamps the cable tray. Then, tighten the locking nut 17 at the bottom of first fastening screw 10 to fix the position of clamping plate 7. At this point, the fixed installation of cable tray and hanger is completed.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
