[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figures 1 to 5 As shown, the present invention provides an insulator bolt limiter. The insulator bolt limiter includes a clamping portion, including two clamping members 3 and a rotating member 11, each clamping member 3 has a pressing area and a clamping area arranged opposite to each other, the rotating member 11 is located between the pressing area and the clamping area, the two clamping members 3 are pivotally connected by the rotating member 11, and a clamping cavity for limiting the bolt is formed between the two clamping areas; an elastic portion, including an elastic member 5, the two pressing areas are arranged at intervals, the elastic member 5 is installed between the two pressing areas, and the elastic member 5 is used to provide the two pressing areas with an elastic force clamping area that is away from each other, so that the two clamping areas are close to each other.

[0027] In the above technical solution, when it is necessary to limit the position of the bolt, the two pressing areas are squeezed so that the two pressing areas are close to each other, and the two clamping members 3 rotate around the rotating member 11, thereby compressing the elastic member 5 to increase the distance between the two clamping areas. In this way, the bolt can be placed in the clamping cavity. By loosening the pressing area, the elastic member 5 can provide an elastic force to move the two pressing areas away from each other, so that the two clamping areas are close to the bolt until the bolt is tightly clamped. In this way, the bolt can be limited; when it is necessary to replace or maintain the bolt, the two pressing areas are squeezed again to make the two pressing areas close to each other, so that the distance between the two clamping areas is increased again, and the clamping cavity is opened. In this way, the bolt can be easily taken out of the clamping cavity for subsequent maintenance or replacement operations. In this way, the phenomenon of difficulty in disassembly of the bolt can be avoided, thereby avoiding the phenomenon of scrapping of the insulator, thereby improving the service life of the insulator.

[0028] Specifically, in the embodiment of the present invention, the elastic member 5 is a spring.

[0029] Specifically, in the embodiment of the present invention, the rotating member 11 is a rotating shaft.

[0030] like Figure 3As shown, in an embodiment of the present invention, the elastic part also includes two connecting components 8, and the two connecting components 8 are correspondingly installed in the two pressing areas. One end of the elastic member 5 is connected to one of the two connecting components 8, and the other end of the elastic member 5 is connected to the other connecting component 8 of the two connecting components 8.

[0031] In the above technical solution, when the bolt needs to be limited, the two pressing areas are squeezed to make the two pressing areas approach each other, and the two connecting members 8 move in the direction of approaching each other, thereby compressing the elastic member 5 to increase the distance between the two clamping areas. In this way, the bolt can be placed in the clamping cavity. By loosening the pressing area, the elastic member 5 can provide an elastic force to make the two pressing areas move away from each other, and the two connecting members 8 move in the direction of moving away from each other. The two clamping areas approach the bolt under the action of the elastic force until the bolt is tightly clamped. In this way, a stable limitation of the bolt can be achieved. By setting two connecting members 8, the phenomenon of deflection or distortion of the elastic member 5 when subjected to force can be avoided, thereby improving the structural stability and reliability of the entire insulator bolt limiter, and ensuring that the elastic member 5 can effectively and accurately transmit the elastic force to the two clamping members 3.

[0032] like Figures 1 to 5 As shown, in the embodiment of the present invention, each clamping member 3 is provided with a slide groove 7 , the slide groove 7 extends along the axis of the rotating member 11 , and the two slide grooves 7 are slidably matched with the two connecting members 8 .

[0033] In the above technical solution, by setting a sliding groove 7 and a connecting member 8 that slide together, the connecting member 8 can slide in the groove 7 so that the connecting member 8 can be installed on the clamping member 3, so that the elastic member 5 can be installed between the two pressing areas. When the aged or damaged elastic member 5 needs to be replaced, the connecting member 8 is slid out of the groove 7, and the elastic member 5 can be removed without disassembling the entire insulator bolt limiter structure. In this way, the maintenance difficulty and maintenance time are reduced, and the maintenance efficiency of the insulator bolt limiter is improved.

[0034] It should be noted that, in the embodiment of the present invention, there is friction between the connecting member 8 and the inner wall surface of the slide groove 7, and under the action of external force applied by the user, the connecting member 8 and the slide groove 7 are slidably matched.

[0035] In one embodiment, the connecting member 8 and the sliding groove 7 are snap-fitted.

[0036] like Figure 3 As shown, in an embodiment of the present invention, the connecting member 8 includes a first connecting member 81; a limiting member, which slidably cooperates with the slide groove 7, and the limiting member includes a first plate segment 82 and a second plate segment 83 that are connected and have successively decreasing cross-sections, and the second plate segment 83 is connected to the elastic member 5 through the first connecting member 81.

[0037] In the above technical solution, if the cross-section of the first plate segment 82 is smaller than the cross-section of the second plate segment 83, the limiting member will disengage from the slide groove 7 along the axial direction of the elastic member 5. This will cause the elastic member 5 to disengage from between the two pressing areas, making it difficult to limit the bolt.

[0038] Specifically, in an embodiment of the present invention, the first plate segment 82, the second plate segment 83 and the first connecting member 81 are arranged in the extension direction of the elastic member 5, and the cross-section of the connecting member 8 is in the shape of an "I" shape, the limiting member is in the shape of a "T" shape, and the slide groove 7 is in the shape of a "T" shape, so that the limiting member can slide and cooperate with the slide groove 7.

[0039] In one embodiment, the first connecting member 81 is disposed inside the slide groove 7 , that is, the slide groove 7 is in an I-shape, and both ends of the elastic member 5 extend into the interiors of the two slide grooves 7 respectively.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in the embodiment of the present invention, a limiting groove 6 is provided on the clamping area of ​​each clamping member 3, and the limiting groove 6 is located on the side of each clamping member 3 facing the clamping cavity, and the limiting groove 6 is constructed to limit the bolt.

[0041] In the above technical solution, when it is necessary to limit the bolt, the two pressing areas are squeezed to make the two pressing areas close to each other, and the two clamping members 3 rotate around the rotating member 11, thereby compressing the elastic member 5 to increase the distance between the two clamping areas. In this way, the bolt can be placed in the two limiting grooves 6 so that the bolt is placed in the clamping cavity. By loosening the pressing areas, the elastic member 5 can provide an elastic force to make the two pressing areas move away from each other, and the two clamping areas approach the bolt under the action of the elastic force. In this way, the bolt can be fixed in the two limiting grooves 6 to achieve stable limiting of the bolt.

[0042] Specifically, in the embodiment of the present invention, the limiting groove 6 can reduce the direct contact between the bolt and the clamping member 3, thereby avoiding damage to the bolt or the clamping member 3 caused by excessive clamping force.

[0043] Specifically, in the embodiment of the present invention, the structure of the limit groove 6 allows the bolt to be embedded in the limit groove 6 when the two clamping areas clamp the bolt, thereby ensuring the precise position of the bolt during and after installation, avoiding displacement of the bolt under external environmental factors (such as vibration), and improving the stability and reliability of the insulator bolt limiter connection.

[0044] Specifically, in the embodiment of the present invention, a non-slip layer is provided on the side of the limiting groove 6 facing the clamping cavity.

[0045] Through the above arrangement, the friction between the bolt and the clamping member 3 can be significantly increased, and even in a high vibration environment, the bolt can be firmly fixed in the limit groove 6 to avoid displacement or loosening of the bolt due to vibration, thereby improving the stability of the entire insulator bolt limiter.

[0046] Specifically, in the embodiment of the present invention, the anti-slip layer is a rubber pad connected to the clamping member 3 .

[0047] Through the above settings, the rubber pad can increase the friction with the bolt while reducing the wear on the bolt surface, which plays an important role in maintaining the integrity of the bolt and extending its service life. It also reduces the risk of unstable electrical connections and safety hazards caused by bolt wear.

[0048] Preferably, in the embodiment of the present invention, the rubber pad is detachably connected to the clamping member 3. In this way, the detachable rubber pad allows maintenance personnel to easily replace the worn rubber pad and adjust the gripping force of the bolt without completely disassembling the insulator bolt limiter, thereby simplifying the maintenance process.

[0049] In one embodiment, the anti-slip layer is an anti-slip pattern provided on the clamping member 3 .

[0050] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the clamping member 3 includes a first rod segment 31, a second rod segment 32 and a third rod segment 33 which are connected and arranged at an angle, the first rod segment 31 forms a pressing area, the third rod segment 33 forms a clamping area, one of the two second rod segments 32 is provided with a mounting groove 9, the other second rod segment 32 of the two second rod segments 32 is penetrated by the mounting groove 9, and the rotating member 11 is penetrated by the two second rod segments 32 to pivotally connect the two second rod segments 32.

[0051] In the above technical solution, on the one hand, the first rod segment 31 is used as a pressing area, providing an operator with a handle for easy force application. In this way, the operator presses the two first rod segments 31 to make the two first rod segments 31 close to each other, and the two clamping members 3 rotate around the rotating member 11, thereby compressing the elastic member 5 to increase the distance between the two clamping areas. In this way, the bolt can be placed in the two limiting grooves 6, so that the bolt is placed in the clamping cavity, thereby improving the convenience of operation; on the other hand, the third rod segment 33 forms a clamping area and the limiting groove 6 is arranged in the clamping area, and the bolt can be embedded in the limiting groove 6, ensuring the stability of the position of the bolt during the limiting process, and effectively preventing the bolt from being displaced due to vibration or external force; on the other hand, the two second rod segments 32 are connected by installing the through groove 9 and the penetration mechanism, and are penetrated by the rotating member 11 to form a pivotable connection structure. The two second rod segments 32 can be flexibly opened and closed with the rotating member 11 as the axis, so as to facilitate the rapid installation and removal of the bolt, while also ensuring the smoothness and stability of the clamping action.

[0052] like Figure 2 and Figure 4 As shown, in the embodiment of the present invention, along the axial direction of the rotating member 11, rotation grooves 10 are provided on both sides of the second rod segment 32 passing through the mounting groove 9, and the second rod segment 32 provided with the mounting groove 9 is installed in the rotation groove 10 and is rotatably arranged in the rotation groove 10.

[0053] Through the above arrangement, during the process of assembling the insulator bolt stopper, the second rod segment 32 provided with the installation through slot 9 can be positioned on the rotation slot 10 to facilitate the penetration of the rotation member 11 .

[0054] Specifically, in the embodiment of the present invention, a third through hole is provided on the bottom wall of the rotating groove 10, a fourth through hole is provided on the second rod section provided with the mounting through hole 9, and the rotating member 11 is connected to the two clamping members 3 through the third through hole and the fourth through hole.

[0055] Specifically, in the embodiment of the present invention, the installation through groove 9 divides part of the second rod segment 32 into a first side plate and a second side plate that are spaced apart, and the first side plate and the second side plate are respectively located in the rotation groove 10 .

[0056] Specifically, in the embodiment of the present invention, a first lubrication groove and a second lubrication groove are provided on the outer periphery of the rotating member 11, the first lubrication groove is provided corresponding to the fourth through hole, and the second lubrication groove is provided corresponding to the third through hole. Lubricant is provided in the first lubrication groove and the second lubrication groove.

[0057] Through the above-mentioned arrangement, the first lubrication groove and the second lubrication groove can accommodate lubricants, such as lubricating oil or grease. When the clamping member 3 rotates around the rotating member 11, these lubricants can be evenly distributed on the contact surface between the rotating member 11 and the clamping member 3, significantly reducing the friction, making the rotation process smoother and the operation more labor-saving.

[0058] Furthermore, in the embodiment of the present invention, the provision of the lubrication groove not only reduces friction, but also indirectly improves the structural stability of the entire insulator bolt stopper. The smooth rotation reduces the uneven stress distribution between components, avoids structural deformation or damage caused by excessive friction, and ensures stability under long-term use.

[0059] Furthermore, in the embodiments of the present invention, in addition to reducing friction, the lubricant can also form a protective layer on the metal surface to prevent the corrosion of the metal surface by moisture, salt or corrosive gases, thereby reducing the risk of rusting of components and extending their service life in harsh environments.

[0060] like Figure 1 , Figure 2 and Figure 5 As shown, in the embodiment of the present invention, the insulator bolt limiter further includes a first cover plate 1 and a second cover plate 2, wherein the first cover plate 1 and the second cover plate 2 are used to enclose a storage cavity, and the two second rod segments 32 and the elastic portion are located in the storage cavity.

[0061] In the above technical solution, the storage cavity enclosed by the first cover plate 1 and the second cover plate 2 can effectively protect the two second rod segments 32, prevent external environmental factors such as dust, moisture and erosion to the two second rod segments 32, thereby extending the service life of the insulator bolt limiter and ensuring the long-term stable working performance of the insulator bolt limiter.

[0062] Furthermore, in the embodiment of the present invention, the arrangement of the first cover plate 1 and the second cover plate 2 facilitates the installation of internal components. The components can be assembled in the storage cavity first and then sealed by the first cover plate 1 and the second cover plate 2, thereby simplifying the assembly process. When maintenance or replacement of internal components is required, only the first cover plate 1 and the second cover plate 2 need to be removed, without the need to disassemble the entire insulator bolt limiter, thereby reducing the difficulty and cost of maintenance.

[0063] Specifically, in the embodiment of the present invention, one of the two first rod segments 31 is provided with an arc-shaped shielding plate, the other of the two first rod segments 31 is provided with a first sliding groove, the first arc-shaped shielding plate is located between the first cover plate 1 and the second cover plate 2, the first arc-shaped shielding plate is located between the two first rod segments 31, and the first arc-shaped shielding plate is slidably matched with the first sliding groove. Similarly, one of the two third rod segments 33 is provided with a second arc-shaped shielding plate, the other of the two third rod segments 33 is provided with a second sliding groove, the second arc-shaped shielding plate is located between the first cover plate 1 and the second cover plate 2, the second arc-shaped shielding plate is located between the two third rod segments 33, and the second arc-shaped shielding plate is slidably matched with the second sliding groove.

[0064] In the above technical solution, the first arc-shaped shielding plate can effectively shield the area between the two first rod segments 31, and the second arc-shaped shielding plate forms a closure for the area between the third rod segments 33, thereby preventing external impurities such as rainwater and dust from entering, reducing corrosion and wear on internal precision components such as the elastic member 5 and the connecting member 8, ensuring the stability and reliability of the bolt limit, and extending the service life of the insulator bolt limiter.

[0065] Specifically, in the embodiment of the present invention, a seal is provided between the first cover plate 1 and the second cover plate 2, so that the sealing between the first cover plate 1 and the second cover plate 2 can be increased, effectively preventing the intrusion of external environmental factors such as moisture, dust or salt spray, and reducing the risk of failure of internal components such as the elastic member 5, the rotating member 11, and the connecting member 8 due to corrosion or wear. This is particularly important for insulator bolt stoppers operating in harsh outdoor environments, which can extend the service life of the insulator bolt stoppers and reduce maintenance costs.

[0066] Furthermore, in the embodiment of the present invention, the enclosed space formed by the seal can maintain the stability of the internal environment, such as reducing the impact of temperature and humidity fluctuations on internal precision components. Under high or low temperature conditions, the seal helps to maintain the relative stability of the internal temperature and prevent the elastic member 5 from degrading due to temperature changes; in a high humidity environment, the seal can effectively reduce the moisture content inside and reduce the risk of component corrosion.

[0067] Furthermore, in the embodiment of the present invention, a seal is added between the first cover plate 1 and the second cover plate 2, which can also play a certain role in shockproofing and noise reduction. The seal usually has a certain elasticity and damping effect, which can absorb and reduce the impact of external vibration on the inside of the limiter. At the same time, the sealing effect reduces the noise transmission during the operation of the equipment and improves the comfort of the working environment.

[0068] Specifically, in the embodiment of the present invention, the first cover plate 1 and the second cover plate 2 are both circular in shape.

[0069] Specifically, in an embodiment of the present invention, the insulator bolt limiter also includes a pressure sensor. The pressure sensor is installed on the contact surface between the clamping member and the bolt, and the clamping force of the clamping member on the bolt can be monitored in real time. In this way, the sensor can monitor whether the bolt is subjected to sufficient clamping force, and whether the clamping force is insufficient or excessive due to changes in external pressure, thereby timely discovering potential bolt loosening or damage to the clamping member 3.

[0070] Specifically, in an embodiment of the present invention, the insulator bolt limiter also includes a vibration sensor, which is arranged on the clamping member 3 or the elastic part. In this way, the vibration condition of the insulator bolt limiter during operation can be monitored. By analyzing the vibration frequency and intensity, the stability of the bolt can be judged, and whether there is a risk of excessive vibration, such as bolt loosening or structural fatigue.

[0071] Specifically, in the embodiment of the present invention, the first cover plate 1 and the second cover plate 2 limit the connection member 8 in the axial direction of the rotating member 11 to prevent the connection member 8 from moving relative to the slide slot 7 along the axial direction of the rotating member 11 and escaping from the slide slot 7.

[0072] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the insulator bolt limiter also includes a plurality of second connecting members 12 , which are arranged at intervals along the circumference of the first cover plate 1 , and are used to connect the first cover plate 1 and the second cover plate 2 .

[0073] In the above technical solution, multiple second connecting members 12 are evenly distributed along the circumference of the first cover plate 1, so that the connection stability between the first cover plate 1 and the second cover plate 2 can be enhanced. In this way, deformation is not easy to occur between the first cover plate 1 and the second cover plate 2, thereby improving the overall structural stability of the insulator bolt limiter.

[0074] Specifically, in the embodiment of the present invention, the design of the second connecting member 12 allows the first cover plate 1 and the second cover plate 2 to be easily connected, which not only simplifies the assembly process of the insulator bolt limiter, but also facilitates the rapid opening of the first cover plate 1 and the second cover plate 2 when replacing internal components (for example, the elastic member 5), thereby reducing maintenance time and cost.

[0075] Specifically, in the embodiment of the present invention, the second connecting member 12 is a bolt, and the number of the second connecting members 12 is two.

[0076] Specifically, in an embodiment of the present invention, a shockproof foam layer is filled between the first cover plate 1 and the second cover plate 2. The shockproof foam layer can be made of materials such as high-density polyethylene or polyurethane, which have good shock absorption performance. The shockproof foam layer is provided with ventilation holes or the shockproof foam layer uses materials with good thermal conductivity to ensure good thermal management and internal temperature control. The foam layer can be installed inside the storage cavity by pasting, embedding or mechanical fixing. Select the most suitable installation method to ensure the stability and replaceability of the foam layer.

[0077] Through the above arrangement, the shockproof foam layer can effectively absorb external shock and vibration, and provide buffer protection for internal precision parts such as the elastic part 5 and the rotating part 11. Foam materials such as high-density polyethylene or polyurethane can deform under the action of external forces due to their good shock absorption performance, absorb and disperse impact energy, reduce the possibility of direct impact on internal parts, thereby reducing the risk of component damage and extending the service life of the entire insulator bolt limiter.

[0078] Furthermore, the ventilation holes designed in the shockproof foam layer or the use of materials with good thermal conductivity can ensure that the internal temperature is controlled to avoid performance degradation due to external high temperature or heat accumulation generated by internal operation. Good thermal management helps to maintain the elastic properties of the elastic member 5 and prevent the elastic member from aging or performance degradation due to excessive temperature; at the same time, the ventilation holes can also promote internal air flow, reduce humidity, reduce the risk of corrosion, and further protect internal components from damage.

[0079] Furthermore, the anti-vibration foam layer can be installed by gluing, embedding or mechanical fixing, and the most suitable installation method can be selected according to the specific design and use environment of the insulator bolt stopper. For example, in situations where the foam layer needs to be replaced frequently, mechanical fixing (such as screw fixing) may be more appropriate; while in applications that require high stability, embedded or gluing installation may be better. Ensuring the stability and replaceability of the foam layer not only facilitates maintenance and replacement, but also ensures that the insulator bolt stopper can maintain good anti-vibration performance after long-term operation or multiple disassembly and assembly.

[0080] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a plurality of first through holes are provided on the first cover plate 1, a plurality of second through holes are provided on the second cover plate 2, the plurality of first through holes are arranged correspondingly to the plurality of second through holes, the insulator bolt limiter also includes a plurality of anti-slip parts 14, the plurality of anti-slip parts 14 are arranged correspondingly to the plurality of first through holes, a plurality of second connecting parts 12 are arranged correspondingly to the plurality of first through holes, and each second connecting part 12 passes through the corresponding first through hole and the corresponding second through hole and then is connected to the corresponding anti-slip part 14.

[0081] In the above technical solution, the anti-dropping member 14 and the second connecting member 12 are used together to ensure a firm connection between the first cover plate 1 and the second cover plate 2, thereby avoiding the separation of the first cover plate 1 and the second cover plate 2 and improving the overall safety and stability of the insulator bolt limiter.

[0082] Specifically, in the embodiment of the present invention, the anti-slipping member 14 is a nut, the number of the anti-slipping members 14 is two, and the number of the first through hole and the number of the second through hole are both two.

[0083] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in the embodiment of the present invention, a plurality of positioning grooves 13 are provided on the side of the second cover plate 2 facing away from the first cover plate 1 , the plurality of positioning grooves 13 are correspondingly connected to the plurality of second through holes, and the plurality of anti-slip components 14 are correspondingly installed in the plurality of positioning grooves 13 .
