Description

Technical Field

[0001] The utility model relates to the technical field of cable clamps, in particular to a buffer clamp for cable installation. Background Art

[0002] The commonly used buffer clamps for cable installation are cable hooks, which can clamp the cables and securely fix them in place. They also act as buffers to prevent the cables from being damaged by excessive pulling or squeezing. They can ensure that the cables remain neat and stable during installation, while reducing the risk of cable damage, effectively improving the efficiency and safety of cable installation.

[0003] Conventional buffer clamps for cable erection usually use the elasticity of the spring slide column to enable the clamp to apply appropriate pressure to the cable. When external pressure is applied or the cable is squeezed, the spring slide column can absorb part of the impact force through compression or elastic deformation.

[0004] Traditional buffer clamps for cable laying have the following problems: since the diameter between the clamps cannot be adjusted, they are only suitable for cables of a specific diameter and are difficult to adapt to cables of different diameters, which limits the flexibility and diversity of applications. In addition, there is a fixed limit on the wrapping length of the cable, and the wrapping length cannot be flexibly adjusted or expanded. For this reason, we propose a buffer clamp for cable laying. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a buffer clamp for cable installation, which can not only adapt to cables of different sizes, but also effectively buffer and fix the cables, flexibly adjust the clamping force, ensure that the cables are safely maintained in place, improve the application scope and flexibility of the buffer clamp, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a buffer clamp for cable installation, comprising an upper clamp, a buffer mechanism and a length adjustment mechanism;

[0007] Upper clamp: The left and right ends of the upper clamp are respectively provided with mounting holes, and the lower clamp is installed inside the mounting holes by bolts, and the central axes of the upper clamp and the lower clamp coincide with each other;

[0008] Buffer mechanism: It includes an internal thread groove, a screw support, a sliding hole, a sliding column, a rubber strip and a second clamp. The internal thread grooves are all opened on the inner arc surface of the upper clamp and the lower clamp. The inner wall of the internal thread groove is threadedly connected with a screw. The end of the screw near the center of the upper clamp is fixedly connected with a support. The inner wall of the support is opened with a sliding hole. The inner wall of the sliding hole is slidably connected with a sliding column. The end of the sliding column near the center of the upper clamp is fixedly connected with the second clamp. The inner arc surface of the second clamp is provided with uniformly distributed rubber strips.

[0009] Length adjustment mechanism: It is arranged inside the second clamping plate, which can not only adapt to cables of different sizes, but also effectively buffer and fix the cables, flexibly adjust the clamping force, ensure that the cables are safely maintained in position, and improve the application range and flexibility of the buffer clamp.

[0010] Furthermore, the central axis of the second clamp plate coincides with the upper clamp and the lower clamp, thereby improving the smoothness of the work.

[0011] Furthermore, the buffer mechanism also includes springs, which are fixedly connected between the outer arc surface of the second clamp and the inner arc surfaces of the adjacent upper clamp and lower clamp. The springs are sleeved on the outer surface of the pillar to play a buffering role.

[0012] Furthermore, the buffer mechanism also includes support rods and sliding openings, and the sliding openings are opened on the inner arc surfaces of the upper clamp and the lower clamp. The inner walls of the sliding openings are slidably connected with support rods, and one end of each two adjacent support rods close to the center of the upper clamp is fixedly connected to the outer arc surface of a clamp plate 2 to provide stable support.

[0013] Furthermore, the buffer mechanism also includes a second knob, and the second knob is fixedly connected to an end of the screw rod away from the center of the upper clamp to drive the buffer mechanism to operate.

[0014] Furthermore, the length adjustment mechanism includes a guide slot and a clamping plate 1, wherein the guide slots are arranged inside the clamping plate 2, and the front and rear ends of the inner wall of the guide slots are slidably connected with the clamping plate 1, so as to change the range of the wrapped cable.

[0015] Furthermore, the length adjustment mechanism also includes a bidirectional screw, a fixed block and a knob 1. The fixed blocks are fixedly connected to the front and rear ends of the second clamp plate. The bidirectional screws are rotatably connected between the fixed blocks. The middle parts of the bidirectional screws are threadedly connected to the adjacent ends of the two clamp plates 1. The front ends of the bidirectional screws are fixedly connected to the knob 1 to drive the length adjustment mechanism to operate.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. According to the size of the cable diameter, the diameter of the second clamping plate is adjusted by rotating the second knob. The rotation of the second knob will drive the screw to rotate. The screw is threadedly connected with the internal thread groove, so that the screw moves along the axis of the internal thread groove. As the screw moves, the support rod is driven to move synchronously along the sliding mouth, so that the rubber strip on the second clamping plate also moves accordingly, and finally contacts closely with the cable. After adjusting to the appropriate diameter, the rubber strip fits tightly around the cable, providing good fixing and insulation effects. The buffer clamp can be flexibly used according to cables of different diameters to ensure that the cable is safely clamped and fixed in place to meet the cable installation and fixation requirements under different requirements.

[0018] 2. When the cable is subjected to external vibration or shaking, the cable clamped in the second clamp will shake, causing the cable to produce an extrusion force on the second clamp. The extrusion force causes the second clamp to move. The displacement of the second clamp will drive the sliding column to move along the inner wall of the sliding hole. The movement of the sliding column will cause the compression of the spring, and at the same time drive the support rod to move synchronously along the inner wall of the sliding mouth. However, the spring is compressed or releases elastic energy due to the influence of displacement and force to adapt to the changes in the shaking of the cable and maintain the balance of the clamping force, thereby playing a buffering role and reducing the impact of external vibration on the cable.

[0019] 3. When it is necessary to extend the wrapping length of the cable, rotate knob one. The rotation of knob one will drive the bidirectional screw to rotate together. The bidirectional screw is threadedly connected with the two adjacent clamps one, thereby realizing the movement of clamp one. The characteristics of the bidirectional screw make clamp one move in opposite directions along the guide groove, so that the range of cable wrapping can be changed by the position of clamp one. The range of cable wrapping can be flexibly adjusted to ensure that the cable is fully buffered and fixed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 , This embodiment provides a technical solution: a buffer clamp for cable installation, comprising an upper clamp 1, a buffer mechanism 5 and a length adjustment mechanism 3;

[0027] Upper clamp 1: The left and right ends thereof are respectively provided with mounting holes 6, and the lower clamp 2 is mounted inside the mounting holes 6 by bolts 4. The central axes of the upper clamp 1 and the lower clamp 2 coincide with each other. First, the bolts 4 on the upper clamp 1 are removed to separate the upper clamp 1 and the lower clamp 2, and then the cable is placed on the inner arc surface of the second clamp plate 511 of the lower clamp 2, and then the upper clamp 1 and the lower clamp 2 are connected together by bolts 4 to form an integral structure;

[0028] Buffer mechanism 5: It includes an internal thread groove 501, a screw 503, a pillar 506, a sliding hole 507, a sliding column 509, a rubber strip 510 and a second clamp 511. The internal thread groove 501 is provided on the inner arc surface of the upper clamp 1 and the lower clamp 2. The inner wall of the internal thread groove 501 is threadedly connected with a screw 503. The end of the screw 503 close to the center of the upper clamp 1 is fixedly connected with the pillar 506. The inner wall of the pillar 506 is provided with a sliding hole 507. The inner wall of the sliding hole 507 is slidably connected with a sliding column 509. The end of the sliding column 509 close to the center of the upper clamp 1 is fixedly connected with the second clamp 511. The inner arc surface of the second clamp 511 is provided with uniformly distributed rubber strips 510. The central axis of the second clamp 511 is The upper clamp 1 and the lower clamp 2 overlap with each other, and the buffer mechanism 5 also includes a spring 508, and the spring 508 is fixedly connected between the outer arc surface of the second clamp 511 and the inner arc surface of the adjacent upper clamp 1 and the lower clamp 2. The spring 508 is sleeved on the outer surface of the pillar 506. The buffer mechanism 5 also includes a support rod 504 and a sliding mouth 505. The sliding mouth 505 is opened on the inner arc surface of the upper clamp 1 and the lower clamp 2. The inner wall of the sliding mouth 505 is slidably connected with the support rod 504, and one end of each two adjacent support rods 504 close to the center of the upper clamp 1 is fixedly connected to the outer arc surface of a second clamp 511. The buffer mechanism 5 also includes a second knob 502, and the second knob 502 is fixedly connected to one end of the screw 503 away from the center of the upper clamp 1. The second clamping plate 511 is then adjusted to the diameter of the cable by rotating the second knob 502. The rotation of the second knob 502 will drive the screw rod 503 to rotate as well. The screw rod 503 is threadedly connected to the internal thread groove 501, so that the screw rod 503 moves along the axis of the internal thread groove 501. As the screw rod 503 moves, the support rod 504 moves synchronously along the sliding opening 505. The rubber strip 510 on the second clamping plate 511 also moves accordingly, and finally comes into close contact with the cable. After adjusting to a suitable diameter, the rubber strip 510 fits tightly around the cable, providing a good fixing and insulating effect. The clamp can be flexibly used according to cables of different diameters to ensure that the cable is safely clamped and The second clamping plate 511 is fixed in position to meet the fixation under different requirements. When the cable is subjected to external vibration or shaking, the cable clamped in the second clamping plate 511 will shake, which will cause the cable to produce an extrusion force on the second clamping plate 511. The extrusion force causes the second clamping plate 511 to move. The displacement of the second clamping plate 511 will drive the sliding column 509 to move along the inner wall of the sliding hole 507. The movement of the sliding column 509 will cause the compression spring 508, and at the same time drive the support rod 504 to move synchronously along the inner wall of the sliding opening 505. However, the spring 508 is affected by the displacement and force and is compressed or releases elastic energy to adapt to the changes in the shaking of the cable and maintain the balance of the clamping force, thereby playing a buffering role and reducing the impact of external vibration on the cable.

[0029] Length adjustment mechanism 3: They are all arranged inside the second clamping plate 511. The length adjustment mechanism 3 includes a guide slot 34 and a clamping plate 1 35. The guide slot 34 is arranged inside the second clamping plate 511. The front and rear ends of the inner wall of the guide slot 34 are slidably connected with the clamping plate 1 35. The length adjustment mechanism 3 also includes a bidirectional screw 31, a fixing block 32 and a knob 1 33. The fixing blocks 32 are fixedly connected to the front and rear ends of the second clamping plate 511. The bidirectional screw 31 is rotatably connected between the fixing blocks 32. The middle part of the bidirectional screw 31 is threadedly connected with the adjacent ends of the two clamping plates 1 35. The front end of the bidirectional screw 31 is fixedly connected with a knob 33. When the wrapping length of the cable needs to be extended, the knob 33 is rotated. The rotation of the knob 33 will drive the bidirectional screw 31 to rotate together. The bidirectional screw 31 is threadedly connected with two adjacent clamps 35, thereby realizing the movement of the clamps 35. Through the characteristics of the bidirectional screw 31, the clamps 35 are moved in opposite directions along the guide groove 34, so that the range of the cable wrapping can be changed by the position of the clamps 35. The range of the cable wrapping can be flexibly adjusted to ensure that the cable is fully buffered and fixed.

[0030] The working principle of the buffer clamp for cable installation provided by the utility model is as follows: first, the bolt 4 on the upper clamp 1 is removed to separate the upper clamp 1 and the lower clamp 2, and then the cable is placed on the inner arc surface of the second clamp plate 511 on the lower clamp 2, and then the upper clamp 1 and the lower clamp 2 are connected together by the bolt 4 to form an integral structure, and then according to the size of the cable diameter, the diameter of the second clamp plate 511 is adjusted by rotating the second knob 502, and the rotation of the second knob 502 will drive the screw rod 503 to rotate, and the screw rod 503 is threadedly connected with the internal thread groove 501. , so that the screw rod 503 moves along the axis of the internal thread groove 501, and the movement of the screw rod 503 drives the support rod 504 to move synchronously along the sliding opening 505, and the rubber strip 510 on the second clamping plate 511 also moves accordingly, and finally contacts closely with the cable. After adjusting to a suitable diameter, the rubber strip 510 fits closely around the cable, providing a good fixing and insulation effect. The clamp can be flexibly used according to cables of different diameters, and ensure that the cable is safely clamped and fixed in place to meet the fixation requirements under different conditions. When the cable is subjected to external vibration or shaking, When the cable clamped in the second clamping plate 511 is moved, the cable will shake, which will cause the cable to exert an extrusion force on the second clamping plate 511. The extrusion force causes the second clamping plate 511 to move. The displacement of the second clamping plate 511 will drive the sliding column 509 to move along the inner wall of the sliding hole 507. The movement of the sliding column 509 will cause the compression spring 508, and at the same time drive the support rod 504 to move synchronously along the inner wall of the sliding opening 505. However, the spring 508 is affected by the displacement and force and is compressed or releases elastic energy to adapt to the changes in the shaking of the cable and maintain the balance of the clamping force, thereby playing a buffering role. The effect is to reduce the impact force of external vibration on the cable. When the wrapping length of the cable needs to be extended, the knob 33 is rotated. The rotation of the knob 33 will drive the bidirectional screw 31 to rotate together. The bidirectional screw 31 is threadedly connected with two adjacent clamps 35, thereby realizing the movement of the clamps 35. Through the characteristics of the bidirectional screw 31, the clamps 35 are moved in opposite directions along the guide groove 34. Therefore, the position of the clamps 35 can change the range of the wrapped cable, and the range of the wrapped cable can be flexibly adjusted to ensure that the cable is fully buffered and fixed.
