Abstract
Description
Technical Field
[0001] This utility model relates to an insulator, specifically a pin-type porcelain insulator, belonging to the field of insulator technology. Background Technology
[0002] Insulators are mostly used on utility poles. A pin insulator is a component used to support or suspend conductors and form electrical insulation between the pole and the conductor. In ordinary ceramic pin insulators, the porcelain part and cast steel are glued together with cement adhesive, and the surface of the porcelain part is coated with a layer of glaze to improve the insulation performance of the insulator.
[0003] Chinese patent application publication number CN222354842U discloses a pin-type porcelain insulator. This pin-type porcelain insulator, by incorporating an installation structure, allows for quick and easy mounting of the pin-type insulator onto the mounting base simply by moving it upwards along the notch on the surface of the mounting base, thus saving installation time.
[0004] Although the above-mentioned patented solution can quickly install insulators using an installation structure, the mounting position of the insulators in the above-mentioned patent is fixed, which is not convenient to adjust the installation position according to the needs of the usage environment. During installation, there is a certain deviation between the insulator installation position and the cable support position, and it is necessary to replace the insulators with different sizes according to the usage environment.
[0005] Therefore, a needle-type porcelain insulator is proposed here. Utility Model Content
[0006] This utility model proposes a pin-type porcelain insulator that can fix the position of the support frame and the connecting frame, so that the position of the insulator body can be adjusted according to the installation needs, and the working height of the insulator body can be adjusted according to the usage environment.
[0007] This utility model is achieved through the following technical solution: a pin-type porcelain insulator, including an insulator body, a supporting threaded rod fixed at the bottom of the insulator body, a support frame provided outside the supporting threaded rod, and a lifting assembly for fixing the position of the support frame provided around the supporting threaded rod. The lifting assembly includes a connecting sleeve threadedly sleeved around the supporting threaded rod, and the connecting sleeve is rotatably sleeved inside the support frame. A transmission sleeve is fixedly sleeved around the connecting sleeve.
[0008] Furthermore, the lifting assembly also includes two limiting rings fixedly sleeved around the periphery of the connecting sleeve, and the two limiting rings are respectively arranged on the upper and lower sides of the support frame.
[0009] Furthermore, the bottom of the supporting threaded rod is threaded with a nut, and the outer diameter of the nut is larger than the outer diameter of the transmission sleeve.
[0010] A connecting frame is slidably sleeved around the periphery of the support frame. A storage groove is provided on one side of the support frame near the connecting frame. A support assembly for fixing the position of the support frame is provided inside the storage groove. The support assembly includes a bidirectional threaded rod rotatably sleeved inside the support frame and two positioning blocks slidably sleeved on the upper and lower sides of the support frame, respectively. Limiting grooves are provided on the sides of the two positioning blocks that are close to each other. Two transmission blocks are threadedly sleeved around the periphery of the bidirectional threaded rod. A support rod is rotatably connected to the upper and lower sides of each transmission block. A connecting rod is rotatably sleeved at the end of the support rod away from the transmission block, and the connecting rod is fixed inside the limiting groove.
[0011] Furthermore, a set of bolt holes is provided at the end of the connecting frame away from the support frame, and a set of positioning holes is provided on both the upper and lower sides of the connecting frame, with the inner diameter of the positioning hole being larger than the outer diameter of the positioning block.
[0012] Furthermore, the two ends of the bidirectional threaded rod are provided with two sections of threads in opposite directions, and one end of the bidirectional threaded rod passes through the support frame and the connecting frame in sequence and is fixedly sleeved with a transmission wheel.
[0013] Furthermore, a movable groove is provided on one side of the connecting frame, and the bidirectional threaded rod slides inside the movable groove.
[0014] This utility model provides a pin-type porcelain insulator, which has the following beneficial effects:
[0015] 1. This pin-type porcelain insulator has a movable support frame that moves inside the connecting frame. The length of the support frame and the connecting frame is adjusted, and then the transmission wheel is rotated to make the bidirectional threaded rod rotate inside the support frame, driving the two transmission blocks to move closer to each other. The support rod and the connecting rod are used to make the positioning block embed into the positioning hole, which can fix the position of the support frame and adjust the position of the insulator body according to the installation requirements.
[0016] 2. This pin-type porcelain insulator features a rotating transmission sleeve, which causes the connecting sleeve to rotate inside the support frame and drives the support threaded rod to move inside the connecting sleeve, allowing the working height of the insulator body to be adjusted according to the usage environment.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0029] Please see Figures 1-4 The present invention proposes the following implementation scheme: a pin-type porcelain insulator, including an insulator body 1, a supporting threaded rod 2 fixed at the bottom of the insulator body 1, a support frame 3 provided outside the supporting threaded rod 2, and a lifting assembly 4 for fixing the position of the support frame 3 provided around the supporting threaded rod 2. The lifting assembly 4 includes a connecting sleeve 41 threadedly sleeved around the supporting threaded rod 2, and the connecting sleeve 41 is rotatably sleeved inside the support frame 3. A transmission sleeve 43 is fixedly sleeved around the connecting sleeve 41.
[0030] Please refer to this carefully. Figure 2 The lifting assembly 4 also includes two limiting rings 42 that are fixedly sleeved around the connecting sleeve 41, and the two limiting rings 42 are respectively arranged on the upper and lower sides of the support frame 3.
[0031] In the above scheme, the rotating transmission sleeve 43 causes the connecting sleeve 41 to rotate inside the support frame 3, and drives the support threaded rod 2 to move inside the connecting sleeve 41, which can adjust the working height of the insulator body 1 according to the usage environment.
[0032] The bottom of the support threaded rod 2 is threaded with a nut 21, and the outer diameter of the nut 21 is larger than the outer diameter of the transmission sleeve 43.
[0033] In the above scheme, the nut 21 is used to prevent the connecting sleeve 41 from moving out of the support threaded rod 2 when adjusting the height.
[0034] Please refer to this carefully. Figure 3 and Figure 4 A connecting frame 5 is slidably sleeved around the support frame 3. A storage groove 31 is provided on the side of the support frame 3 near the connecting frame 5. A support component 6 is provided inside the storage groove 31 to fix the position of the support frame 3. The support component 6 includes a bidirectional threaded rod 61 rotatably sleeved inside the support frame 3 and two positioning blocks 65 slidably sleeved on the upper and lower sides of the support frame 3 respectively. Limiting grooves 66 are provided on the side of the two positioning blocks 65 that are close to each other. Two transmission blocks 62 are threadedly sleeved around the bidirectional threaded rod 61. A support rod 63 is rotatably connected to the upper and lower sides of each transmission block 62. A connecting rod 64 is rotatably sleeved at the end of the support rod 63 away from the transmission block 62, and the connecting rod 64 is fixed inside the limiting groove 66.
[0035] Please refer to this carefully. Figure 3 A set of bolt holes 52 is provided at the end of the connecting frame 5 away from the support frame 3.

One end of the bidirectional threaded rod 61 passes through the support frame 3 and the connecting frame 5 in sequence and is fixedly sleeved with the transmission wheel 67.
[0037] In the above scheme, rotating the transmission wheel 67 causes the bidirectional threaded rod 61 to rotate inside the support frame 3, driving the two transmission blocks 62 to move closer to each other. The support rod 63 and the connecting rod 64 are used to embed the positioning block 65 into the positioning hole 51, which can fix the position of the support frame 3.
[0038] Please refer to this carefully. Figure 3 One side of the connecting frame 5 is provided with a moving groove 53, and the bidirectional threaded rod 61 slides inside the moving groove 53.
[0039] In the above scheme, when the support frame 3 slides inside the connecting frame 5, the bidirectional threaded rod 61 can move inside the moving groove 53.
[0040] In use, the connecting frame 5 is placed in the installation position and fixed with external bolts and bolt holes 52. The insulator body 1 is held and the transmission sleeve 43 is rotated, causing the connecting sleeve 41 to rotate inside the support frame 3 and drive the support threaded rod 2 to move inside the connecting sleeve 41. The working height of the insulator body 1 can be adjusted according to the usage environment. Then, the support frame 3 is moved inside the connecting frame 5 to adjust the length of the support frame 3 and the connecting frame 5. Then, the transmission wheel 67 is rotated, causing the bidirectional threaded rod 61 to rotate inside the support frame 3, driving the two transmission blocks 62 to move closer to each other. The positioning block 65 is embedded in the positioning hole 51 by the support rod 63 and the connecting rod 64, which can fix the position of the support frame 3 and the connecting frame 5, and adjust the position of the insulator body 1 according to the installation requirements.
