[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1 In the prior art, the cable is generally buffered directly by a spring connection clamp. However, when the spring is compressed to the limit distance, the impact force is ultimately directly applied to the insulator. At the same time, when the cable is swayed by wind, it is also easy to move inside the clamp, and eventually the cable is likely to fall off the clamp, which is not conducive to the stable transmission of electricity by the cable. Therefore, this embodiment is invented to solve the above problem.

[0028] like Figures 1 to 7The present embodiment provides an insulator assembly, including an insulator body 1, the insulator body 1 is composed of a connecting rod 101 and a plurality of insulating members 102, one end of the connecting rod 101 is fixedly connected to a support frame 2, a constraint mechanism 3 is slidably arranged in the support frame 2, and is used to constrain the cable, the constraint mechanism 3 includes a guide rail 301 fixedly connected to the support frame 2, a connecting block 302 is slidably connected in the guide rail 301, an end of the connecting block 302 away from the connecting rod 101 is fixedly connected to a wire clamp 303, an end of the connecting block 302 close to the connecting rod 101 is fixedly connected to a push rod 304, and the free end of the push rod 304 contacts the end surface of the guide block 502.

[0029] The anti-slip mechanism 4 is arranged between the support frame 2 and the constraint mechanism 3, and is used to constrain the cable in the constraint mechanism 3. The anti-slip mechanism 4 includes two connecting rods 401 hinged with the guide block 502, and the free end of the connecting rod 401 is hinged with a push block 402, and the push block 402 is slidably connected to the support frame 2. Both ends of the wire clamp 303 are slidably connected with anti-slip plates 403, and the end of the anti-slip plate 403 away from the wire clamp 303 is fixedly connected with a guide rod 404, and the free end of the guide rod 404 contacts with the corresponding push block 402. When the push block 402 slides, it can drive the guide rod 404 to slide, and sliding grooves 405 are opened on both sides of the support frame 2, and a slider 406 is slidably connected in the sliding groove 405, and the slider 406 is fixedly connected to the corresponding push block 402. A third elastic member 407 is provided between the anti-slip plate 403 and the wire clamp 303.

[0030] The buffer mechanism 5 is arranged on the support frame 2, and the buffer mechanism 5 includes a mounting groove 501 opened on the support frame 2, and a guide block 502 is slidably connected in the mounting groove 501. When the constraint mechanism 3 slides horizontally, the constraint mechanism 3 can drive the guide block 502 to slide axially along the connecting rod 101. The upper end surface of the guide block 502 is composed of an inclined surface 5021 and a vertical surface 5022. The two groups of inclined surfaces 5021 and the vertical surface 5022 are mirror-arranged, and the two inclined surfaces 5021 are connected.

[0031] Multiple insulating parts 102 are equidistantly sleeved on the connecting rod 101, and the multiple insulating parts 102 are all umbrella-shaped. The other end of the connecting rod 101 is fixedly connected to a fixing rod 103, and the axial cross-section of the fixing rod 103 is an inverted T-shape. One end of the connecting rod 101 close to the fixing rod 103 is threadedly connected to a limiting nut 104.

[0032] In actual use, the connecting rod 101 is first fixed to the conductor crossarm through the fixing rod 103 and the limiting nut 104, and then the cable is placed on the wire clamp 303. When the cable is subjected to the force of wind, the force generated by the swing of the cable is applied to the wire clamp 303. When the wind force is too small, under the action of the friction between the guide block 502 and the mounting groove 501, the two inclined surfaces 5021 on the guide block 502 can prevent the top rod 304 from moving laterally, so that the top rod 304 drives the wire clamp 303 to maintain a stable position through the connecting block 302, avoiding the problem that the wire clamp 303 can move when the wind force is too small, reducing the situation where the swing force acts on the insulating component 102 through the support frame 2 and the connecting rod 101, and facilitating the improvement of the service life of the insulating component 102.

[0033] When the wind is strong, the wind drives the wire clamp 303 to shake through the cable, so that the wire clamp 303 drives the connecting block 302 to slide along the guide rail 301, and the connecting block 302 drives the top rod 304 to move, so that the top rod 304 pushes the guide block 502 to slide along the placement groove 501 toward the direction of the connecting rod 101 through the inclined surface 5021 on the guide block 502, and the vertical surface 5022 on the guide block 502 limits the movement range of the top rod 304, and the guide block 502 slides downward to drive the connecting rod 401 to slide downward, so that the lateral impact force is reduced, and at the same time the connecting rod 401 drives the push block 402 to move downward, and the push block 402 drives the slider 406 to slide downward along the slide groove 405. Since the end surface of the push block 402 close to the wire clamp 303 is an inclined surface, and the upper end of the push block 402 The thickness is greater than that of its lower end. As the wire clamp 303 slides in the direction of one of the push blocks 402, the push block 402 can quickly push a guide rod 404 to slide in the direction of the wire clamp 303. The guide rod 404 quickly drives an anti-slip plate 403 to slide in the interior of the wire clamp 303. The third elastic member 407 is compressed. As the wire clamp 303 drives another guide rod 404 to gradually move away from the push block 402, the other anti-slip plate 403 slides in the interior of the wire clamp 303 slowly. At this time, the anti-slip plate 403 that quickly slides into the interior of the wire clamp 303 can block the opening of the wire clamp 303, thereby preventing the cable from falling off from the inside of the wire clamp 303 during the process of the cable driving the wire clamp 303 to swing, thereby providing stability for the cable in the wire clamp 303.

[0034] In summary, by configuring the guide block 502, the anti-slip plate 403, the top rod 304, the connecting rod 401 and the push block 402, not only can the wire clamp 303 be in a stable position under the action of the friction between the guide block 502, the push block 402 and the support frame 2 when the cable is subjected to too small a wind force, thereby reducing the problem of the wire clamp 303 sliding when subjected to a small force, but also reducing the vibration force transmitted to the insulating member 102 through the support frame 2 and the connecting rod 101, thereby facilitating the improvement of the service life of the insulating member 102, and at the same time, when the wind force is too large, When the impact force is large, the lateral impact force can be decomposed through the guide block 502, the connecting rod 401 and the push block 402, reducing the impact force acting on the insulating part 102 through the support frame 2 and the connecting rod 101, and enabling one of the anti-slip plates 403 to quickly block the opening of the wire clamp 303, thereby preventing the cable from falling off from the wire clamp 303 when the cable drives the wire clamp 303 to slide, thereby improving the stability of the cable in the wire clamp 303, reducing the vibration force on the insulating part 102, and increasing the service life of the insulating part 102.

[0035] Embodiment 2 During use, it was found that when the insulator encounters extremely cold weather, the internal material of the insulator produces a large stress change due to thermal expansion and contraction. If the antifreeze performance of the material is poor, tiny cracks are easily generated inside. When the wind is too strong, after the wire clamp 303 slides to the maximum stroke, the impact force directly acts on the support frame 2, so that the impact force is transmitted to the connecting rod 101 through the support frame 2 and then acts on the insulating member 102. At this time, the insulating member 102 is subjected to the impact force for a long time. At this time, it is easy to cause the internal structure of the insulating member 102 to expand cracks over time and with the continuous action of stress, and eventually cause the insulator to rupture. Therefore, further improvements are made based on the above embodiments.

[0036] like Figures 2 to 5 As shown, the vibration reduction mechanism 6 is arranged between the support frame 2 and the connecting rod 101, and the vibration reduction mechanism 6 includes a sleeve 601 movably connected to the connecting rod 101, and an adjusting rod 602 is movably connected inside the sleeve 601. The end of the adjusting rod 602 away from the sleeve 601 is fixedly connected to the guide block 502. When the adjusting rod 602 slides along the sleeve 601 to the threshold, the adjusting rod 602 drives the sleeve 601 to slide and rotate, so as to reduce the lateral impact force.

[0037] The vibration damping mechanism 6 also includes a vibration damping groove 603 provided in the connecting rod 101, the sleeve 601 and the adjusting rod 602 are both located in the vibration damping groove 603, a guide groove 604 is provided on the circumferential side of the sleeve 601, an auxiliary rod 605 is fixedly connected to the inner wall of the vibration damping groove 603, and the free end of the auxiliary rod 605 is inserted into the guide groove 604. When the sleeve 601 slides, under the action of the auxiliary rod 605 and the guide groove 604, the sleeve 601 rotates along the vibration damping groove 603, a first elastic member 606 is provided between the vibration damping groove 603 and the sleeve 601, and a second elastic member 607 is provided between the sleeve 601 and the adjusting rod 602, and the elastic force of the first elastic member 606 is greater than the elastic force of the second elastic member 607.

[0038] In actual use, when the wire clamp 303 drives the guide block 502 to slide downward along the mounting groove 501 through the connecting block 302 and the top rod 304, the guide block 502 drives the adjusting rod 602 to slide downward along the supporting frame 2. Since the elastic force of the first elastic member 606 is greater than the elastic force of the second elastic member 607, when the adjusting rod 602 slides downward along the sleeve 601, the second elastic member 607 is compressed. At this time, the impact force received by the wire clamp 303 is decomposed into a part of the downward force, which plays the first vibration reduction role.

[0039] When the wind force continues to increase, the second elastic member 607 is compressed to the limit state, and the adjusting rod 602 continues to slide downward along the connecting rod 101. The adjusting rod 602 drives the sleeve 601 to slide downward along the connecting rod 101 through the second elastic member 607. The first elastic member 606 is compressed, and an inclined guide groove 604 is opened on the circumferential side of the sleeve 601. At the same time, under the action of the auxiliary rod 605 on the inner wall of the vibration reduction groove 603, when the sleeve 601 slides downward along the vibration reduction groove 603, under the joint action of the guide groove 604 and the auxiliary rod 605 Downward, the sleeve 601 rotates along the vibration reduction groove 603, thereby decomposing the downward component force into a part of the force used for the rotation of the sleeve 601. At this time, not only can the impact force on the wire clamp 303 be decomposed into multiple levels, but also the impact force is prevented from directly acting on the insulating part 102 through the connecting rod 101, thereby reducing the influence of the impact force on the insulating part 102 and improving the service life of the insulating part 102. When the wind force gradually decreases to disappear, the above movement is repeated in the reverse direction, so that the wire clamp 303 drives the cable to return to the center position of the support frame 2 to maintain stability.

[0040] To sum up, through the arrangement of the sleeve 601, the adjustment rod 602, the first elastic member 606, the second elastic member 607, the guide groove 604 and the auxiliary rod 605, not only can the impact force received by the wire clamp 303 be decomposed into a downward force for overcoming the elastic force of the second elastic member 607 for a vibration reduction, but the force exceeding the threshold of the second elastic member 607 can also be decomposed again through the sleeve 601, and the sleeve 601 can be rotated to reduce the impact force. At this time, it is possible to avoid the excessive impact force directly acting on the insulating member 102 through the support frame 2 and the connecting rod 101. Through the multi-stage vibration reduction and decomposition of the impact force, the insulating member 102 is effectively prevented from being affected by the impact force for a long time, and the internal breakage of the insulating member 102 in bad weather is avoided. At the same time, the service life of the insulating member 102 can be effectively improved.

[0041] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
