The surface of the clamping plate that moves upward will contact and squeeze the surface of the connecting column, so that the clamping plate begins to deflect and drives the torsion spring to deform. As the upper surface of the top plate contacts the bottom surface of the connecting column, the reaction force generated by the deformation of the torsion spring drives the clamping plate to reset and clamp the connecting column, so as to achieve a more stable connection and prevent it from falling off.

[0016] 2. The present invention provides an annular sac, a pressure plate, an elastic baffle and other components that cooperate with each other. When the top plate rises, the pressure plate will be driven to rise synchronously and compress the gas inside the limit rod. When the surface of the top plate contacts the lower surface of the connecting column, the top rod will contact and press the upper surface of the elastic baffle to open the through groove, so that the compressed gas inside the limit rod enters the interior of the through groove and enters the interior of the annular sac through the circular groove, so that the annular sac expands and contacts the inner wall of the groove, thereby preventing dust and rain water from entering the bottom of the top plate, facilitating the subsequent replacement of the insulator body and saving replacement time.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0033] Combined with Figure 1 -Attached Fig.11, and also includes an anti-dropping component 3 for preventing the insulator body 1 from falling off after the connection is completed, so that when multiple groups of insulator bodies 1 are connected, they can be quickly connected and fixed to prevent them from falling off; the anti-dropping component 3 includes an upper swivel ring 301 rotatably connected to the middle position of the steel cap 2, and a lower swivel ring 302 is attached below the upper swivel ring 301. By arranging the upper swivel ring 301 and the lower swivel ring 302, the middle part of the steel cap 2 can be rotated; it is worth mentioning that a through hole is provided at the center of the upper swivel ring 301 and the lower swivel ring 302, and the inner wall of the through hole provided on the surface of the upper swivel ring 301 is provided with a thread, and the lower swivel ring 302 is rotatably connected to the steel cap 2; a positioning groove 3021 is provided on the upper surface of the lower swivel ring 302, and the positioning groove 3021 is smoothly connected to the upper surface of the lower swivel ring 302 through an arc surface, and the positioning groove 3021 is provided to play a positioning role;

[0034] Among them, an elastic telescopic rod 3022 is inserted into the inner wall of the positioning groove 3021, and the upper end of the elastic telescopic rod 3022 is fixedly connected to the lower surface of the upper swivel ring 301. By setting the elastic telescopic rod 3022, the upper swivel ring 301 and the lower swivel ring 302 can be connected to each other and can rotate synchronously. At the same time, through the setting of the arc surface, the upper swivel ring 301 can only rotate alone when rotating in the opposite direction, and will not drive the lower swivel ring 302 to rotate synchronously; two groups of matching blocks 303 are symmetrically installed on the lower surface of the lower swivel ring 302, and by setting the matching blocks 303, it can rotate synchronously with the lower swivel ring 302; the lower end of the matching block 303 is slidably matched with a one-way toothed ring 304, and the one-way toothed ring 304 is arranged inside the annular groove opened inside the steel cap 2. By setting the one-way toothed ring 304, it can play a role The cam 3041 is a spring loaded part of the first cam 3041 and a spring loaded part of the first cam 3042 is a spring loaded part of the first cam 3042. The cam 3041 is a spring loaded part of the first cam 3042 and a spring loaded part of the first cam 3042 is a spring loaded part of the first cam 3042.

[0035] The screw rod 305 with a hollow structure inside is meshedly connected to the interior of the upper rotating ring 301, and the screw rod 305 is arranged inside the groove 202. By setting the screw rod 305, it can cooperate with the upper rotating ring 301 to achieve the purpose of lifting. It is worth mentioning that when the upper rotating ring 301 rotates clockwise, the lower rotating ring 302 will be driven to rotate synchronously through the cooperation of the elastic telescopic rod 3022 and the positioning groove 3021, and the screw rod 305 will be driven to move upward at the same time. When the upper rotating ring 301 is reversed, the lower rotating ring 302 cannot rotate under the cooperation of the matching block 303 and the one-way gear ring 304. At this time, the elastic telescopic rod 3022 will begin to shrink and move out of the positioning groove 3021, so that the upper rotating ring 301 rotates in the opposite direction alone, driving the screw rod 305 to move downward.

[0036] Among them, two groups of vertical grooves 3051 are symmetrically opened on the inner wall of the screw rod 305, a hollow limit rod 3052 is provided inside the screw rod 305, and the limit rod 3052 is fixedly installed on the bottom surface of the groove 202, and two groups of sliders 3053 are symmetrically installed on the surface of the limit rod 3052, and the sliders 3053 are slidably matched with the inner wall of the vertical groove 3051. By setting the vertical groove 3051, the limit rod 3052 and the slider 3053, the rising screw rod 305 can be limited to avoid the screw rod 305 from rotating synchronously when the upper rotating ring 301 rotates; two groups of push rods 3054 are symmetrically installed on the inner top surface of the screw rod 305, and by setting the push rod 3054, a pressing effect can be achieved.

[0037] Among them, a top plate 306 is fixedly installed on the surface of the screw rod 305. By setting up the top plate 306, it can rise and fall synchronously with the screw rod 305, and support the other group of connecting columns 101 inside the installation groove 201 to prevent shaking; two groups of connecting blocks 307 are symmetrically installed on the surface of the top plate 306, and the two sides of the two groups of connecting blocks 307 are movably connected with clamping plates 308 through torsion springs. The top surface of the clamping plate 308 on the side close to the connecting column 101 is provided with an inclined surface, and the contact surface with the surface of the connecting column 101 is an arc surface, which is used for The connecting column 101 is clamped and a clamping plate 308 is provided so that it can rise synchronously with the top plate 306. When the surface of the clamping plate 308 contacts the surface of the connecting column 101, it deflects and drives the torsion spring to deform. When the upper surface of the top plate 306 contacts the top surface of another group of connecting columns 101, the clamping plate 308 no longer squeezes it, and thus resets under the reaction force generated by the deformation of the torsion spring and is clamped on the surface of the connecting column 101, thereby fixing the connecting column 101 and preventing it from falling off.

[0038] Combined with Figure 1 -Attached Fig.11, and also includes a sealing component 4 for sealing the groove 202, so that after the two sets of insulator bodies 1 are connected, the groove 202 can be sealed to prevent rain and dust from entering the interior, which is convenient for subsequent replacement and saves replacement time; the sealing component 4 includes an annular capsule 401 with an annular structure embedded in the surface of the top plate 306, and the annular capsule 401 is provided, so that it can be expanded to contact the inner wall of the groove 202 to form a seal for the groove 202; it is worth noting that the annular capsule 401 is made of materials in the prior art, such as silicone rubber, fluorosilicone rubber, ethylene propylene rubber and other materials with corrosion characteristics such as resistance to sunlight and rain;

[0039] The annular capsule 401 is connected to the vertical rod 402 through the circular groove opened inside the top plate 306. The upper end of the vertical rod 402 is fixedly connected to the lower surface of the top plate 306, and the lower end of the vertical rod 402 is inserted into the inside of the limiting rod 3052. By setting the vertical rod 402, it can rise and fall synchronously with the top plate 306. It is worth noting that the connection between the vertical rod 402 and the upper end of the limiting rod 3052 is sealed by a sealing gasket. It is worth noting that the sealing gasket is a conventional , not shown in the figure; a pressing plate 403 is fixedly installed at the lower end of the vertical rod 402, and the pressing plate 403 is in contact with the inner wall of the limiting rod 3052. By setting the pressing plate 403, it can move synchronously with the vertical rod 402, and at the same time, the purpose of compressing the gas can be achieved; two groups of through grooves 404 connected to the inside of the limiting rod 3052 are symmetrically opened inside the pressing plate 403, and the through grooves 404 are connected to the vertical rod 402. By opening the through grooves 404, the gas delivery is convenient;

[0040] Among them, the ends of the two groups of through grooves 404 are elastically connected with elastic baffles 405. By setting the elastic baffles 405, the through grooves 404 can be sealed in the initial state to prevent the gas from entering the interior of the through grooves 404 when the pressure plate 403 just rises; the elastic baffles 405 are arranged directly below the top rod 3054, and the diameter of the upper end of the elastic baffles 405 is larger than the diameter of the top rod 3054. By making the diameter of the upper end of the elastic baffles 405 larger than the diameter of the top rod 3054, when the top rod 3054 presses the elastic baffles 405, the air inlet of the through grooves 404 will not be blocked, so that the gas can enter the interior of the through grooves 404 and be transported to the interior of the annular capsule 401, so that the annular capsule 401 expands and seals the groove 202.

[0041] Specifically, when two groups of insulator bodies 1 are connected, one group of connecting posts 101 is first installed inside the installation groove 201 of the other group, and then the upper rotating ring 301 and the lower rotating ring 302 are rotated clockwise, and the upper rotating ring 301 is engaged with the screw rod 305, so that the screw rod 305 starts to drive the top plate 306 to move upward, and the upwardly moving top plate 306 drives the clamping plates 308 symmetrically arranged on its surface to move synchronously and start to contact the surface of the connecting post 101;

[0042] When the upper surface of the clamping plate 308 contacts the surface of the connecting column 101, as the top plate 306 continues to rise, the upper surface of the clamping plate 308 will be squeezed and deflected therewith, and the torsion spring will be deformed. When the top surface of the top plate 306 contacts the bottom surface of the connecting column 101, the clamping plate 308 will no longer be squeezed against the surface of the connecting column 101. At this time, the clamping plate 308 will reset under the reaction force generated by the torsion spring and get stuck on the surface of the connecting column 101, thereby fixing the connecting column 101 and preventing it from falling off.

[0043] During the rising process of the screw rod 305, the vertical rod 402 installed on the bottom surface of the top plate 306 will be driven to rise synchronously. At the same time, the pressure plate 403 installed at the lower end of the vertical rod 402 will also rise and begin to compress the gas inside the limit rod 3052. When the top plate 306 contacts the bottom surface of the connecting column 101, the top rod 3054 presses the elastic baffle 405 to open the through groove 404, allowing the gas to enter the interior of the one-way gear ring 304 and be transported to the annular capsule 401, so that the annular capsule 401 expands and contacts the inner wall of the groove 202, thereby achieving the purpose of sealing and facilitating the subsequent replacement of the insulator body 1.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
