Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to an M-shaped pad with a positioning effect. Background Technology

[0002] In power equipment, the M-type shim is a metal accessory used to connect crossarms and poles. It is named for the "M"-shaped arc surface on the side that contacts the pole. It is a key component in the installation of overhead power distribution lines, and its main function is to enhance the stability and reliability of the connection between the crossarm and the pole. Traditional flat shims or simple arc-surface shims lack targeted design and are prone to problems such as loose fit and inaccurate positioning. The M-type shim, on the other hand, is optimized for the connection scenario between the pole and the crossarm. It has a higher arc surface fit and can further improve positioning accuracy and stability through structural innovation, making it a more reliable choice for power line installation.

[0003] Existing positioning structures for shims and utility poles are simple, relying mostly on the frictional force after bolt tightening for fixation. They lack specialized limiting components, requiring repeated adjustments to ensure installation accuracy, significantly increasing construction time and labor costs. Therefore, this utility model was developed to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: an M-shaped pad with positioning effect, comprising: a pad body, a positioning structure fixedly connected to the back of the pad body, a stabilizing structure fixedly connected to the front of the pad body, the positioning structure including an upper positioning plate, a positioning groove formed on the upper positioning plate, an upper anti-sliding block fixedly connected to the inner wall of the positioning groove, a stabilizing spring fixedly connected to the bottom of the upper positioning plate, a lower positioning plate fixedly connected to the bottom of the stabilizing spring, a lower anti-sliding block fixedly connected to the top of the lower positioning plate, and a stabilizing rod slidably connected to the bottom of the upper positioning plate.

[0005] Preferably, the stabilizer bar passes through the stabilizer spring and extends to both sides, and the bottom of the stabilizer bar is fixedly connected to the top of the lower positioning plate.

[0006] Preferably, the pad body includes a connecting plate, and a support block is fixedly connected to the outer wall of the connecting plate.

[0007] Preferably, the outer wall of the connecting plate is provided with bolt holes, and the back of the connecting plate is fixedly connected to the outer wall of the upper positioning plate.

[0008] Preferably, a stabilizing block is fixedly connected to the outer wall of the support block, and the stabilizing block is arranged linearly along the support block.

[0009] Preferably, the outer wall of the stabilizing block is provided with a stabilizing groove, and a rubber block is fixedly connected to the outer wall of the stabilizing groove.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a positioning structure, allows the positioning groove of the upper positioning plate to directly engage with the edge of the pole to achieve initial positioning. Combined with the frictional force of the upper and lower anti-slip blocks, pre-positioning can be completed without relying on bolt tightening. The elastic force of the stabilizing spring can adapt to differences in pole diameter, causing the lower positioning plate to automatically conform to the pole surface, reducing the number of manual adjustments, significantly shortening construction time, and lowering labor costs. The stabilizing rod passes through the stabilizing spring and connects the upper and lower positioning plates, limiting their relative positions and preventing lateral displacement during spring extension and contraction, ensuring that the positioning structure always maintains a stable fit with the pole. This reduces construction difficulty and maintenance costs, and has practical value and promotional significance.

[0011] 2. This utility model, through the setting of a stabilizing structure, not only buffers the vibration of the power equipment during operation and reduces the swaying between the shim and the pole, but also avoids hard friction between the stabilizing block and the pole, reducing the wear of both. At the same time, the pre-tightening force design of the positioning structure can compensate for bolt loosening during long-term use, ensuring the long-term reliability of the positioning effect and extending the overall service life of the equipment. The stabilizing groove of the stabilizing block is adapted to the protrusions or connectors on the surface of the pole, and the rubber block fills the gap through elastic deformation, which can adapt to the irregular shape of different pole surfaces and significantly improve the fit.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.

Example

[0015] Please see Figure 1 - Figure 2 This utility model provides a technical solution: an M-shaped pad with positioning effect, comprising: a pad body 1, a positioning structure 2 fixedly connected to the back of the pad body 1, and a stabilizing structure 3 fixedly connected to the front of the pad body 1. The positioning structure 2 includes an upper positioning plate 21, a positioning groove 22 formed in the upper positioning plate 21, an upper anti-slip block 23 fixedly connected to the inner wall of the positioning groove 22, a stabilizing spring 24 fixedly connected to the bottom of the upper positioning plate 21, a lower positioning plate 26 fixedly connected to the bottom of the stabilizing spring 24, a lower anti-slip block 27 fixedly connected to the top of the lower positioning plate 26, and a stabilizing rod 25 slidably connected to the bottom of the upper positioning plate 21, the stabilizing rod 25 passing through the stabilizing spring 24 and... Extending to both sides, the bottom of the stabilizing rod 25 is fixedly connected to the top of the lower positioning plate 26, and the pad body 1 is attached to the surface of the pole. The upper positioning plate 21 and the lower positioning plate 26 in the positioning structure 2 are respectively placed on both sides of the pole. The positioning groove 22 opened in the upper positioning plate 21 is used to hold the edge of the pole. The upper anti-sliding block 23 on the inner wall increases the friction with the pole. Pull the positioning plate 26 to adjust its position so that the lower anti-sliding block 27 is tightly attached to the pole. Then, release the positioning plate 26, the stabilizing spring 24 contracts, and drives the stabilizing rod 25 to slide along the bottom of the upper positioning plate 21. This not only limits the relative position of the upper and lower positioning plates, but also enhances the stability when the spring is extended and retracted, preventing the positioning structure 2 from shifting, and achieving initial positioning and fixing.

[0016] Please see Figure 3 The shim body 1 includes a connecting plate 11, a support block 12 is fixedly connected to the outer wall of the connecting plate 11, and bolt holes 13 are opened on the outer wall of the connecting plate 11. The back of the connecting plate 11 is fixedly connected to the outer wall of the upper positioning plate 21, aligning the connecting plate 11 with the crossarm angle steel. The support block 12 fits against the surface of the crossarm to provide auxiliary support. By passing bolts through the bolt holes 13 on the outer wall of the connecting plate 11, the shim body 1 is fastened to the crossarm. At this time, the upper positioning plate 21 on the back of the connecting plate 11 is fixed with the position of the shim, ensuring the accurate relative position of the positioning structure 2 and the pole. The support block 12 enhances the stability of the contact between the connecting plate 11 and the crossarm, prevents the shim body 1 from deforming during the fastening process, and ensures the firmness of the overall installation structure.

[0017] Please see Figure 4 A stabilizing block 31 is fixedly connected to the outer wall of the support block 12. The stabilizing blocks 31 are arranged linearly along the support block 12. A stabilizing groove 32 is opened on the outer wall of the stabilizing groove 32. A rubber block 33 is fixedly connected to the outer wall of the stabilizing groove 32. After the crossarm is connected to the pad body 1, the stabilizing blocks 31 are arranged linearly along the support block 12. The stabilizing groove 32 on its outer wall is adapted to the protrusions or connectors on the surface of the pole to increase the contact area. The rubber block 33 in the stabilizing groove 32 tightly fills the gap due to elastic deformation, further reducing the shaking between the pad and the pole. The rubber block 33 can also buffer the vibration of the power equipment during operation, avoid the hard friction between the stabilizing block 31 and the pole, and prevent wear. At the same time, it enhances the overall stability of the connection between the pad body 1 and the pole, ensuring long-term reliable positioning effect.

[0018] Working principle: In use, the shim body 1 is attached to the surface of the pole. The upper positioning plate 21 and the lower positioning plate 26 in the positioning structure 2 are placed on both sides of the pole. The positioning groove 22 of the upper positioning plate 21 is used to hold the edge of the pole. The upper anti-sliding block 23 on the inner wall increases the friction with the pole. The lower positioning plate 26 is pulled to adjust its position so that the lower anti-sliding block 27 is tightly attached to the pole. Then the lower positioning plate 26 is released, the stabilizing spring 24 retracts, and the stabilizing rod 25 slides along the bottom of the upper positioning plate 21. This limits the relative position of the upper positioning plate 21 and the lower positioning plate 26 and enhances the stability of the spring during extension and retraction, preventing the positioning structure 2 from shifting and achieving initial positioning and fixation. The connecting plate 11 is aligned with the crossarm angle steel, and the support block 12 is attached to the surface of the crossarm to provide auxiliary support. The shim body 1 is fastened to the crossarm by bolts passing through the bolt holes 13 on the outer wall of the connecting plate 11. At this time, the upper positioning plate 21 on the back of the connecting plate 11 is fixed with the position of the shim, ensuring the accurate relative position of the positioning structure 2 and the pole. The support block 12 enhances the stability of the contact between the connecting plate 11 and the crossarm, prevents the shim body 1 from deforming during the fastening process, and ensures the firmness of the overall installation structure. After the crossarm is connected to the shim body 1, the stabilizing block 31 in the stabilizing structure 3 is linearly arranged along the support block 12. The stabilizing groove 32 on its outer wall is adapted to the protrusions or connectors on the surface of the pole, increasing the contact area. The rubber block 33 in the stabilizing groove 32 tightly fills the gap due to elastic deformation, further reducing the shaking between the shim and the pole. The rubber block 33 can also buffer the vibration of the power equipment during operation, avoid the hard friction between the stabilizing block 31 and the pole, and enhance the overall stability of the connection between the shim body 1 and the pole, ensuring the long-term reliability of the positioning effect.
