Description

Technical Field

[0001] This utility model relates to the field of surge arrester technology, specifically a surge arrester with an installation structure. Background Technology

[0002] The main function of a surge arrester is to protect electrical equipment from damage caused by high transient overvoltages. Under normal conditions, it exhibits a high resistance state, with only microampere-level current passing through it. However, under the influence of overvoltage and high current, the surge arrester will exhibit a low resistance state, thereby limiting the residual voltage across the surge arrester and protecting the equipment from damage.

[0003] When using existing surge arresters, their function is to protect electrical equipment from damage caused by high transient overvoltages. Existing surge arresters are connected and fixed with screws. However, when the spacing between the brackets and the spacing between the screw holes on the bottom surface of the surge arrester are different, the screws cannot be positioned, which can easily lead to problems affecting the normal installation of the surge arrester. Utility Model Content

[0004] The purpose of this utility model is to provide a surge arrester with an installation structure to solve the problem mentioned in the background art that existing surge arresters are connected and fixed with screws, but when the bracket spacing is different from the screw hole spacing on the bottom surface of the surge arrester, the screws cannot be positioned, which easily leads to the problem of affecting the normal installation of the surge arrester.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surge arrester with an installation structure, comprising:

[0006] The device body includes a surge arrester body, with brackets connected to both sides of the bottom of the surge arrester body, and a support frame provided at the bottom of the brackets;

[0007] The support frame has an installation structure inserted inside both sides of its bottom end. The installation structure includes a limiting slide rod. A limiting ring is sleeved on the outer wall of the limiting slide rod. A threaded rod is connected to the top of the limiting slide rod. A nut is rotatably connected to the outer surface of the top of the threaded rod. A couple support spring is connected inside one side of the threaded rod. A limiting block is connected to one end of the support spring.

[0008] Preferably, the upper and lower end surfaces of the support frame are respectively provided with a through groove one and a through groove two, the threaded rod is inserted into the through groove one of the support frame, and the limiting slide rod is inserted into the through groove two of the support frame.

[0009] Preferably, the bracket has through holes on both ends, the top end of the threaded rod is inserted into the through holes of the bracket, and the threaded rod and the nut are rotatably connected by threads.

[0010] Preferably, a groove is provided on one side of the threaded rod, and one end of the support spring is connected to one side of the inner wall of the groove provided on the threaded rod.

[0011] Preferably, the bottom end of the threaded rod is connected to a limiting structure, the limiting structure includes a positioning rod, the two sides of the positioning rod are connected to limiting plates, a bolt is inserted inside the positioning rod, and a rubber gasket is sleeved on the outer wall of the positioning rod.

[0012] Preferably, a positioning groove is formed on the top surface of the limiting slide rod, the positioning rod is inserted into the positioning groove formed by the limiting slide rod, and limiting grooves are formed on both sides of the inner wall of the positioning groove formed by the limiting slide rod, and the limiting plate is inserted into the limiting groove formed by the limiting slide rod.

[0013] Preferably, a slot is provided on one side of the inner wall of the positioning groove of the limiting slide rod, and a threaded hole is provided on the surface of the positioning rod. One end of the bolt passes through the slot of the limiting slide rod and is rotatably connected to the threaded hole of the positioning rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the nut to the outer surface of the threaded rod tip, the threaded rod is limited. When adjusting the spacing of the bracket, rotate the nut in the opposite direction and press the limiting block to compress the support spring, thereby moving the limiting block into the groove of the threaded rod. Disassemble the nut, and then move the position of the threaded rod so that the threaded rod and the limiting slide rod slide in the through slot one and through slot two of the support frame, respectively. Use the limiting ring in conjunction with the limiting slide rod to limit the threaded rod, so that the threaded rod will not detach from the support frame. After the spacing adjustment is completed, rotate the nut back to the outer surface of the threaded rod tip to limit the threaded rod. This allows for quick installation between the bracket and the support frame, avoiding the problem of screws not being able to be positioned due to different spacing, which would affect normal installation.

[0016] 2. By attaching a rubber gasket to the outer surface of the positioning rod, and then inserting the positioning rod connected to the bottom end of the threaded rod into the positioning groove of the limiting slide rod, the limiting plate is simultaneously inserted into the limiting groove of the limiting slide rod, thus limiting the angle of the positioning rod. Then, one end of the bolt is passed through the slot of the limiting slide rod and rotated to the threaded hole of the positioning rod to limit the positioning rod. The rubber gasket is used to fill the space between the limiting slide rod and the threaded rod for buffering, so that the two make flexible contact, thereby achieving the limiting effect between the limiting slide rod and the threaded rod.

[0025] A surge arrester with an installation structure includes:

[0026] The device body 1 includes a surge arrester body 11. The surge arrester body 11 has brackets 12 connected to both sides of its bottom. A support frame 13 is provided at the bottom of the brackets 12. The internal material of the support frame 13 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application. Therefore, no further details are made.

[0027] The support frame 13 has an installation structure 2 inserted inside both sides of its bottom end. The installation structure 2 includes a limiting slide rod 21. A limiting ring 22 is sleeved on the outer wall of the limiting slide rod 21. A threaded rod 23 is connected to the top of the limiting slide rod 21. A nut 24 is rotatably connected to the outer surface of the top of the threaded rod 23. A couple support spring 25 is connected inside one side of the threaded rod 23. A limiting block 26 is connected to one end of the support spring 25.

[0028] Furthermore, the upper and lower surfaces of the support frame 13 are respectively provided with through groove 1 and through groove 2. The threaded rod 23 is inserted into through groove 1 of the support frame 13, and the limiting slide rod 21 is inserted into through groove 2 of the support frame 13, so that the limiting slide rod 21 can be moved and limited through through groove 2 of the support frame 13.

[0029] Furthermore, through holes are provided on both ends of the bracket 12, and the top end of the threaded rod 23 is inserted into the through hole of the bracket 12. The threaded rod 23 and the nut 24 are rotatably connected by threads, so as to limit the movement between the threaded rod 23 and the nut 24 by threads.

[0030] Furthermore, a groove is provided on one side of the threaded rod 23, and one end of the support spring 25 is connected to one side of the inner wall of the groove provided in the threaded rod 23, so that the groove provided in the threaded rod 23 can limit one end of the support spring 25.

[0031] Furthermore, the bottom end of the threaded rod 23 is connected to a limiting structure 3, which includes a positioning rod 31. The positioning rod 31 is connected to two limiting plates 32 on both sides. A bolt 33 is inserted inside the positioning rod 31, and a rubber gasket 34 is sleeved on the outer wall of the positioning rod 31 to achieve the limiting function between the limiting slide rod 21 and the threaded rod 23.

[0032] Furthermore, a positioning groove is provided on the top surface of the limiting slide rod 21, and the positioning rod 31 is inserted into the positioning groove of the limiting slide rod 21. Limiting grooves are provided on both sides of the inner wall of the positioning groove of the limiting slide rod 21, and the limiting plate 32 is inserted into the limiting groove of the limiting slide rod 21, so as to limit the limiting plate 32 through the limiting groove of the limiting slide rod 21.

[0033] Furthermore, a slot is provided on one side of the positioning groove of the limiting slide rod 21, and a threaded hole is provided on the surface of the positioning rod 31. One end of the bolt 33 passes through the slot of the limiting slide rod 21 and is rotatably connected to the inside of the threaded hole of the positioning rod 31, so as to connect and fix the limiting slide rod 21 and the positioning rod 31 by means of the bolt 33.

[0034] Working principle: When installing the surge arrester, the nut 24 is rotated and connected to the outer surface of the top of the threaded rod 23 to limit the threaded rod 23. When adjusting the spacing of the bracket 12, the nut 24 is rotated in the opposite direction and the limiting block 26 is pressed to retract the support spring 25, thereby moving the limiting block 26 into the groove of the threaded rod 23. The nut 24 is then disassembled, and the position of the threaded rod 23 is moved so that the threaded rod 23 and the limiting slide 21 slide in the through slot one and through slot two of the support frame 13, respectively. The limiting ring 22, in conjunction with the limiting slide 21, limits the threaded rod 23, preventing it from detaching from the support frame 13. After the spacing adjustment is completed, the nut 24 is rotated and reconnected to the outer surface of the top of the threaded rod 23 to limit the threaded rod 23, thus achieving a quick installation between the bracket 12 and the support frame 13.

[0035] When limiting the position of a surge arrester with an installation structure, a rubber gasket 34 is fitted onto the outer surface of the positioning rod 31, and then the positioning rod 31 connected to the bottom end of the threaded rod 23 is inserted into the positioning groove of the limiting slide rod 21. At the same time, the limiting plate 32 is inserted into the limiting groove of the limiting slide rod 21 to limit the angle of the positioning rod 31. Then, one end of the bolt 33 is passed through the slot of the limiting slide rod 21 and rotated to the threaded hole of the positioning rod 31 to limit the positioning rod 31. The rubber gasket 34 is used to fill the space between the limiting slide rod 21 and the threaded rod 23 for buffering, so that the two make flexible contact, thereby achieving the limiting effect between the limiting slide rod 21 and the threaded rod 23.
