Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a combined disc insulator. Background Art

[0002] Insulators are devices installed between conductors at different potentials or between conductors and grounded structures, which can withstand voltage and mechanical stress.

[0003] At present, a Chinese utility model with publication number CN219393063U discloses a through-hole disc insulator, which uses the cooperation of multiple traction plates, positioning plates, springs and bosses to position the flange, avoiding the problem of the insulator and the flange being easily detached after a long time of bonding.

[0004] However, since each traction plate is independent of each other and there is a lack of positioning components for the traction plates, the installation of the flange is very troublesome. Therefore, the utility model proposes a combined disc insulator to solve the above problem. Utility Model Content

[0005] The utility model aims to provide a combined disc insulator to solve the problem in the background art that the installation of the flange is very troublesome because each traction plate is independent of each other and the device lacks a positioning assembly for the traction plate.

[0006] To achieve the above object, the utility model provides the following technical solution: a combined disc insulator, the combined disc insulator comprising:

[0007] An insulator body, wherein a boss is fixedly connected to the side of the insulator body, a plurality of conductors are fixedly connected to one end of the insulator body, a plurality of circular holes are opened on one side of the insulator body, and a flange is slidably sleeved on one end of the insulator body;

[0008] A card plate, the card plate is located at one end of the insulator body and is fixedly connected to the insulator body, a plurality of traction plates distributed in a circumferential array are slidably inserted on the side of the card plate, a pressure plate and a limit plate are fixedly connected to one side of the traction plate, and a plurality of placement grooves for sliding and inserting the pressure plates are provided on the side of the insulator body;

[0009] A threaded rod, wherein the threaded rod is located at one end of the insulator body and is threadedly plugged into the insulator body, the threaded rod is located at the center of the clamping plate and a fixed block is fixedly connected to the side of the threaded rod, and the fixed block is arranged in an inverted "truncated cone shape".

[0010] Preferably, one end of the insulator body is provided with a mounting groove for threaded insertion of the threaded rod, and the side surface of the clamping plate is provided with a plurality of sliding grooves for sliding insertion of the traction plate.

[0011] Preferably, one end of the traction plate is arranged to be in an inclined "arc shape", and the upper end surface of the fixing block is higher than the upper end surface of the traction plate.

[0012] Preferably, one end of the clamping plate is fixedly connected with a plurality of convex plates, and the side of the convex plate is slidably connected with a limit block for limiting the rotation of the threaded rod, and the limit block is arranged in a "V" shape and a spring is arranged between the limit block and the convex plate.

[0013] Preferably, one end of the limit block is fixedly connected to a fixing rod, and the fixing rod is slidably plugged into the convex plate and plugged into the spring.

[0014] Preferably, one end of the fixing rod close to the limiting block is fixedly connected with a spiral protrusion, and a threaded groove for the fixing rod to be inserted is formed through the side surface of the protruding plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The device drives the fixed block to slide toward the end of the insulator body by rotating the threaded rod. After the fixed block slides, it can squeeze multiple traction plates and slide toward the outer ring of the insulator body at the same time. After the traction plate slides, it can position the flange sleeved on the insulator body to ensure that the flange will not slide out of the insulator body. When the flange needs to be removed, it is only necessary to rotate the threaded rod to keep the fixed block away from the insulator body. At this time, the multiple traction plates will no longer be restricted and can directly slide and engage with the insulator body to make the sliding surface required by the flange available, making the installation and removal of the flange very convenient. This solves the problem that the installation of the flange is very troublesome due to the independence of each traction plate and the lack of a positioning component for the traction plate on the device.

[0027] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0028] See also Figures 1 to 6 , the utility model provides a technical solution:

[0029] Embodiment 1 is a combined disc insulator, which includes: an insulator body 1 , a clamping plate 4 and a threaded rod 6 .

[0030] Specifically, a boss 2 is fixedly connected to the side of the insulator body 1, a plurality of conductors 11 are fixedly connected to one end of the insulator body 1, a plurality of round holes 12 are opened on one side of the insulator body 1, a flange 3 is slidably sleeved on one end of the insulator body 1, and the flange 3 falls on the boss 2 after being sleeved with the insulator body 1, and the boss 2 supports the flange 3 to prevent the flange 3 from sliding out from the other end of the insulator body 1;

[0031] Secondly, the clamping plate 4 is located at one end of the insulator body 1 and is fixedly connected to the insulator body 1. A plurality of traction plates 5 distributed in a circumferential array are slidably inserted on the side of the clamping plate 4. A pressure plate 51 and a limit plate 52 are fixedly connected to one side of the traction plate 5. A plurality of placement grooves 14 for the pressure plates 51 to be slidably inserted are provided on the side of the insulator body 1.

[0032] Furthermore, the threaded rod 6 is located at one end of the insulator body 1 and is threadedly plugged with the insulator body 1. The threaded rod 6 is located at the center of the card plate 4 and a fixing block 7 is fixedly connected to the side of the threaded rod 6. The fixing block 7 is set to an inverted "truncated cone shape". In actual implementation, the flange 3 is first sleeved on the insulator body 1, and the flange 3 is allowed to sit on the boss 2. Then the threaded rod 6 is rotated. As the threaded rod 6 penetrates deeper into the insulator body 1, the inverted "truncated cone-shaped" fixing block 7 will push multiple traction plates 5 and slide in a direction away from the card plate 4 at the same time. As the traction plate 5 slides, the pressure plate 51 will slide out of the placement groove 14 and then be clamped on the flange 3. Prevent the flange 3 from sliding out of the insulator body 1 and ensure that the flange 3 is stably installed on the insulator body 1. When the flange 3 needs to be removed, rotate the threaded rod 6 to make the threaded rod 6 away from the insulator body 1. At this time, the fixing block 7 will also move away from the insulator body 1 along with the threaded rod 6, thereby releasing the pressure on the traction plate 5. At this time, slide the traction plate 5 toward the end of the card plate 4, and let the pressure plate 51 slide and then insert into the placement groove 14, thereby releasing the positioning of the flange 3, so that the flange 3 can directly slide out of the insulator body 1, which is very convenient. The cooperation between the limit plate 52 and the edge protrusion of the end of the insulator body 1 can prevent the traction plate 5 from sliding off the card plate 4.

[0033] In order to facilitate the installation of the traction plate 5 and the threaded rod 6, one end of the insulator body 1 of the present application is provided with a mounting groove 13 for threaded insertion of the threaded rod 6, and the side of the clamping plate 4 is provided with a plurality of sliding grooves 41 for sliding insertion of the traction plate 5. The mounting groove 13 can facilitate the threaded insertion of the threaded rod 6, and the sliding groove 41 can fix the sliding track of the traction plate 5.

[0034] In order to better promote the sliding of the traction plate 5, one end of the traction plate 5 of the present application is set to an inclined "arc shape", which can ensure that the fixed block 7 can reduce wear when pushing the traction plate 5 to slide. The upper end surface of the fixed block 7 is higher than the upper end surface of the traction plate 5, which can ensure that the fixed block 7 can push the traction plate 5 to the required position.

[0035] In order to ensure further stability of the traction plate 5 after it slides into place, one end of the clamping plate 4 of the present application is fixedly connected with multiple protruding plates 8, and the side of the protruding plate 8 is slidably connected to a limit block 9 for limiting the rotation of the threaded rod 6. The limit block 9 is arranged in a "V" shape and a spring 92 is arranged between the limit block 9 and the protruding plate 8. After the traction plate 5 slides into place, the limit block 9 is released, and the "V"-shaped limit block 9 and the threaded rod 6 are engaged under the action of the spring 92, thereby limiting the rotation of the threaded rod 6, thereby further ensuring the stability of the traction plate 5, which also ensures the further stability of the installation of the flange 3.

[0036] In order to facilitate the installation of the limit block 9, one end of the limit block 9 of the present application is fixedly connected with a fixing rod 91, and the fixing rod 91 is slidably inserted into the convex plate 8 and the spring 92. The fixing rod 91 can provide the limit block 9 with space for sliding installation, thereby facilitating the limit block 9 to provide the threaded rod 6 with operating space.

[0037] In order to better fix the limit block 9, the fixing rod 91 of the present application is fixedly connected with a spiral protrusion 93 at one end close to the limit block 9, and a threaded groove for the fixing rod 91 to be inserted is opened through the side of the convex plate 8. When it is necessary to limit the limit block 9 from sliding toward the end of the threaded rod 6, the fixing rod 91 is pulled to slide in the direction away from the threaded rod 6. After the spiral protrusion 93 contacts the convex plate 8, the fixing rod 91 is rotated. As the spiral protrusion 93 goes deeper, the limit block 9 is fixed to ensure that the limit block 9 will not slide toward the threaded rod 6.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
