Description

Technical Field

[0001] This application relates to the field of power fittings, specifically to a deformation-resistant pipe fitting for fixing. Background Technology

[0002] Tube busbar fixing fittings are electrical fittings used to fix tubular busbars to post insulators or post insulators with clamps. They play a key role in supporting the safe operation of busbar systems in power plants and substations.

[0003] Chinese patent document CN211183293U discloses a busbar fitting, specifically a base. An upper clamp and a lower clamp are mounted on the base and pressed together, forming a support channel for the busbar to pass through. A support rod facing the base is provided on the lower clamp, and a limiting plate is provided at the lower end of the support rod. A receiving groove for inserting the limiting plate is provided on the base. A fixing plate is sleeved on the support rod between the lower clamp and the limiting plate. A sliding rod along the height of the support rod is provided on the base, and the fixing plate is slidably mounted on the sliding rod. A spring is sleeved on the sliding rod to press the fixing plate against the limiting plate. This patent allows for convenient adjustment of the direction of the support channel, thereby facilitating the installation of the busbar.

[0004] However, in the aforementioned patent, the inner wall of the support channel is smooth, which means that the base and the tube nut are fixed only by the clamping force of the upper and lower clamps in the vertical direction. This leads to horizontal movement between the base and the tube nut, affecting the fixing effect of the tube nut. Utility Model Content

[0005] In order to overcome the problem of poor fixing effect of existing fixing mechanisms on the nut, this application provides a deformation-resistant nut fixing connection hardware.

[0006] This application adopts the following technical solution: a deformation-resistant pipe nut fixing connection hardware, including a support base and a fixing component disposed on the support base, the fixing component including an upper clamp and a lower clamp, the bottom of the upper clamp is provided with an upper groove, the top of the lower clamp is provided with a lower groove, the upper groove and the lower groove together form a fixing channel, the fixing channel is used to fix the pipe nut, a limiting component is provided in the lower groove, the limiting component includes a limiting strip, the limiting strip is movably disposed in the upper groove;

[0007] Both ends of the limiting strip are wedge-shaped, and the ends of the limiting strip can be pressed against the inside of the nut.

[0008] Optionally, the upper clamp and the lower clamp are connected by bolts, and the ends of the upper groove and the lower groove are aligned with each other.

[0009] Optionally, the lower groove is provided with two through grooves, which extend along the length of the lower groove and penetrate through it. The side of the limiting strip that is in contact with the lower groove is provided with two sliders, which are respectively and correspondingly located in the two through grooves. The sliders can slide in the through grooves.

[0010] Optionally, the opening width of the through groove is smaller than the bottom width of the through groove, and the outer wall of the slider is in contact with the inner wall of the through groove.

[0011] Optionally, the slider is provided with a threaded hole that penetrates the slider along the length of the through groove. Each through groove is provided with a lead screw. One end of the lead screw is screwed into the threaded hole of one slider in the corresponding through groove, and the other end of the lead screw is screwed into the threaded hole of another slider in the corresponding through groove. The threads at the two ends of the lead screw are in opposite directions.

[0012] Optionally, a receiving groove is provided at both ends of the inner wall of the upper groove and at both ends of the inner wall of the lower groove. An elastic sealing element is adaptedly provided in the receiving groove. Two elastic sealing elements located at the same end of the upper groove and the lower groove are connected to each other to form an elastic sealing ring.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. A limiting strip is provided in the lower groove. Both ends of the limiting strip are wedge-shaped, and the ends of the limiting strip can be pressed against the inner side of the tube nut. Through the wedge-shaped structure of the end of the limiting strip and the pressing fit with the inner side of the tube nut, the tube nut can be effectively limited in the horizontal direction, thereby restricting the horizontal movement of the tube nut and greatly improving the fixing effect of the tube nut.

[0015] 2. The limiting strip is movably located in the upper groove. When installing the nut, the position of the limiting strip can be adjusted by rotating the screw, so as to adapt to different installation environments and installation requirements, and can also reliably fix different nuts.

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figure 1-5 As shown, a deformation-resistant pipe nut fixing fitting includes a support base 1 and a fixing component disposed on the support base 1. The fixing component includes an upper clamp 2 and a lower clamp 3. The bottom of the upper clamp 2 is provided with an upper groove 21, and the top of the lower clamp 3 is provided with a lower groove 31. The shapes of the upper groove 21 and the lower groove 31 can be designed according to the shape of the pipe nut, usually an arc shape adapted to the outer diameter of the pipe nut, to ensure that the upper clamp 2 and the lower clamp 3 can better fit the surface of the pipe nut. The upper groove 21 and the lower groove 31 together form a fixing channel 22, which is used to fix the pipe nut and can restrict the vertical movement of the pipe nut. The upper clamp 2 and the lower clamp 3 are connected by bolts 23. During installation, the nut is placed in the lower groove 31, and then the upper clamp 2 is covered. The two are fastened together by bolts 23, so that the ends of the upper groove 21 and the lower groove 31 are aligned with each other to form a complete fixing channel 22, thereby achieving reliable fixing of the nut.

[0024] A limiting component is provided in the lower groove 31, including a limiting strip 4, which is movably disposed in the upper groove 21. Both ends of the limiting strip 4 are wedge-shaped. Thus, during the process of bolt 23 locking the upper clamp 2 and the lower clamp 3, the distance between the end of the limiting strip 4 and the outer wall of the tube nut will be greater than the distance between the middle of the limiting strip 4 and the outer wall of the tube nut. This allows the limiting strip 4 to cut into the inner side of the tube nut more easily, causing a slight deformation of the outer wall of the tube nut, thereby restricting the horizontal movement of the tube nut and maximizing the fixing effect of the tube nut.

[0025] The lower groove 31 has two through slots 311, which extend along the length of the lower groove 31 and penetrate through it. Two sliders 41 are provided on the side of the limiting strip 4 that is in contact with the lower groove 31. The two sliders 41 are respectively and correspondingly located within the two through slots 311, allowing them to slide within the slots 311. The outer wall of the slider 41 is in contact with the inner wall of the through slot 311, ensuring smooth sliding within the slot 311 without shaking or jamming. The opening width of the through slot 311 is smaller than the bottom width, preventing the sliders 41 from detaching from the slot and ensuring the stability of the limiting strip 4's movement. The slider 41 is provided with a threaded hole 410, which extends through the slider 41 along the length of the through groove 311. Each through groove 311 contains a lead screw 42. One end of the lead screw 42 is screwed into the threaded hole 410 of one slider 41 in the corresponding through groove 311, and the other end is screwed into the threaded hole 410 of the other slider 41 in the corresponding through groove 311. The threads at both ends of the lead screw 42 rotate in opposite directions. When the lead screw 42 is rotated, because the threads at both ends rotate in opposite directions, the two sliders 41 move simultaneously in opposite directions, thereby causing the limiting strip 4 to slide within the through groove 311, thus adjusting the position of the limiting strip 4. The position adjustment of the limiting strip 4 can be performed from the outside of the fixed assembly, i.e., adjusting the distance between the two limiting strips 4 before placing the slider 41 into the through groove 311, or the slider 41 can be placed into the through groove 311 first, and then the lead screw 42 can be rotated to adjust the position of the limiting strip 4.

[0026] Both ends of the inner wall of the upper groove 21 and both ends of the inner wall of the lower groove 31 are provided with a receiving groove 24. An elastic sealing element 240 is adaptedly provided within the receiving groove 24. Two elastic sealing elements 240 located at the same end of the upper groove 21 and the lower groove 31 abut against each other to form an elastic sealing ring. The elastic sealing element 240 can be made of rubber. The elastic sealing ring can prevent dust, moisture, and other impurities from entering the fixed channel 22, protecting the nut from the influence of the external environment, and also reducing friction and wear between the nut and the fixed component.

[0027] The implementation principle of this embodiment is as follows: This anti-deformation pipe nut fixing fitting, by setting a limiting component, utilizes the wedge-shaped design at the end of the limiting strip 4 to press against the inner side of the pipe nut, effectively preventing horizontal movement of the pipe nut and improving the fixing effect. Simultaneously, through the cooperation of the lead screw 42 and the slider 41, the position of the limiting strip 4 can be easily adjusted to accommodate pipe nuts of different diameters and maximize the fixing effect. The elastic sealing ring further protects the pipe nut and extends its service life.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
