Description

Technical Field

[0001] This utility model relates to the field of clamp technology, and in particular to a telescopic clamp structure. Background Technology

[0002] A clamp is a device used to connect and fix pipes, fittings or other round objects. It is usually composed of two halves of a clamp. The two halves are connected by a locking bolt to achieve the connection between pipes and fittings. However, after the clamp is tightened, it can only maintain a certain locking force. When the two pipes are subjected to force and move outward, the clamp cannot maintain a good clamping force and is prone to falling off.

[0003] Existing technologies, such as CN205278620U, and the aforementioned utility model, use fixed connecting ears at both ends of the upper and lower clamping rings to provide concentric mounting bolts that can symmetrically and evenly tighten the pipe through the mounting bolt holes. This ensures that the outer wall of the pipe is subjected to balanced force and does not deform during the tightening process, achieving the best anti-slip, vibration reduction, and energy dissipation effect. It effectively solves the shortcomings of traditional clamps that cannot prevent slippage, ensures the safety of pipes and personnel, and reduces maintenance costs.

[0004] While the aforementioned patent solves the problem that the clamp cannot maintain a good clamping fit when the two pipes move outward under force, which can easily lead to detachment, the overall clamp length is fixed. In the working environment, when there is a gap between the pipes, it is difficult to directly adapt. It often requires a lot of time to find suitable connecting parts or modify existing parts. The installation process is not flexible and convenient enough. The clamp is not easy to adjust flexibly according to the gap, making it difficult to effectively connect the pipes and causing inconvenience in overall use. Summary of the Invention

[0005] The purpose of this utility model is to provide a telescopic clamp structure that solves the problem of fixed clamp length, which makes it difficult to directly adapt when there is a gap between pipes in the working environment.

[0006] To achieve the above objectives, this utility model provides a telescopic clamp structure, including an upper clamp first, an upper clamp second, a lower clamp first, and a lower clamp second. Locking bolts are inserted into both the upper clamp first and upper clamp second, and these bolts are threadedly connected to the inner walls of the lower clamp first and lower clamp second. The structure also includes a telescopic device. The telescopic device comprises two extension rings and a movable ring. The two extension rings are fixedly connected to the surfaces of the upper clamp second and lower clamp second, respectively, and the two movable rings are fixedly connected to the surfaces of the upper clamp first and lower clamp first, respectively. A sliding cavity is formed on the surface of each extension ring, and a slider is fixedly connected to one end of each movable ring. The slider is slidably connected to the inner wall of the sliding cavity. Adjustment portions are provided between the upper clamp first and lower clamp first and the extension rings. Reinforcing portions are provided between the upper clamp first and upper clamp second, and between the lower clamp first and lower clamp second.

[0007] The adjusting part includes a hollow seat fixed to the outer surfaces of the upper clamp and the lower clamp. An adjusting screw is rotatably connected to the inner wall of the hollow seat. A threaded seat is fixedly connected to the outer surface of the extension ring. The adjusting screw is threadedly connected to the inner wall of the threaded seat. Through the above components, when operating the adjusting part, the adjusting screw can be rotated. The adjusting screw can rotate in the hollow seat. Then, the adjusting screw, in conjunction with the hollow seat, can control the slider and the movable ring to move in the sliding cavity on the surface of the extension ring.

[0008] The reinforcing part includes multiple supporting slide rods fixed to one side surface of the upper clamp and the lower clamp. Multiple hollow sleeve rods are fixedly connected to one side surface of the upper clamp and the lower clamp. The supporting slide rods are slidably connected to the inner wall of the hollow sleeve rods. Through the above components, when the supporting slide rods move in the hollow sleeve rods, not only can the stability be improved, but the overall strength can also be improved.

[0009] Each of the upper clamping ears (first, second, first, and second) is equipped with an auxiliary device, which includes multiple anti-slip pads located on the inner side of each clamping ear. Inserts are fixedly connected to the surface of each anti-slip pad. Slots are provided on the inner side of each clamping ear, and the inserts are inserted into the inner wall of the slots. Through these components, after installation, the anti-slip pads can contact and compress the pipe fitting, thereby improving overall stability and anti-slip properties. Furthermore, if the anti-slip pads are damaged, the inserts can be removed from the slots for replacement.

[0010] The longitudinal section of the insert block is T-shaped.

[0011] The anti-slip pad has an anti-slip groove on its inner side and is made of rubber.

[0012] This utility model discloses a telescopic clamp structure. Through the control unit, the slider and the movable ring can move in the sliding cavity within the extension ring, thereby realizing the telescopic adjustment of the distance between the upper clamp ear 1 and the upper clamp ear 2, as well as the distance between the lower clamp ear 1 and the lower clamp ear 2. This allows it to adapt to different installation requirements, quickly fill gaps in pipe spacing, and flexibly adapt to pipe connection requirements with different spacings. Whether in standard installation scenarios or non-standard spacings caused by construction errors or special designs, a stable connection can be achieved through adjustment, expanding the application range of the clamp.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-5 A telescopic clamp structure includes an upper clamp 1, an upper clamp 2, a lower clamp 3 and a lower clamp 4. Locking bolts 7 are inserted into the upper clamp 1 and the upper clamp 2. The locking bolts 7 are threaded to the inner walls of the lower clamp 3 and the lower clamp 4. The structure also includes a telescopic device.

[0022] Specifically, the telescopic device includes two extension rings 51 and two movable rings 53. The two extension rings 51 are fixedly connected to the surfaces of the upper clamping ear 2 and the lower clamping ear 4, respectively. The two movable rings 53 are fixedly connected to the surfaces of the upper clamping ear 1 and the lower clamping ear 3, respectively. A sliding cavity 59 is formed on the surface of the extension rings 51. A slider 52 is fixedly connected to one end of the movable ring 53. The slider 52 is slidably connected to the inner wall of the sliding cavity 59. Adjustment parts are provided between the upper clamping ear 1 and the lower clamping ear 3 and the extension rings 51. Adjustment parts are provided between the upper clamping ear 1 and the upper clamping ear 2, and between the lower clamping ear 3 and the lower clamping ear 2. Each of the four parts is provided with a reinforcing part. The adjusting part includes a hollow seat 54 fixed to the outer surface of the upper clamp 1 and the lower clamp 3. An adjusting screw 55 is rotatably connected to the inner wall of the hollow seat 54. A threaded seat 56 is fixedly connected to the outer surface of the extension ring 51. The adjusting screw 55 is threadedly connected to the inner wall of the threaded seat 56. The reinforcing part includes multiple supporting slide rods 58 fixed to one side surface of the upper clamp 1 and the lower clamp 3. Multiple hollow sleeve rods 57 are fixedly connected to one side surface of the upper clamp 2 and the lower clamp 4. The supporting slide rods 58 are slidably connected to the inner wall of the hollow sleeve rods 57.

[0023] In this embodiment: During adjustment, the adjusting screw 55 can be rotated, and the adjusting screw 55 can rotate in the hollow seat 54. Then, the adjusting screw 55, together with the hollow seat 54, can control the slider 52 and the movable ring 53 to move in the sliding cavity 59 on the surface of the extension ring 51. When the supporting slide rod 58 moves in the hollow sleeve rod 57, it can not only improve stability, but also improve the overall strength, thereby adapting to different installation requirements, quickly filling the gap in pipe spacing, without the need to re-customize or modify the pipe, and greatly shortening the construction time.

[0024] Specifically, auxiliary devices are provided in the upper clamp 1, upper clamp 2, lower clamp 3, and lower clamp 4. The auxiliary devices include multiple anti-slip pads, which are located on the inner side of the upper clamp 1, upper clamp 2, lower clamp 3, and lower clamp 4, respectively. Insert blocks 62 are fixedly connected to the surface of the anti-slip pads. The longitudinal section of the insert blocks 62 is T-shaped. Slots 63 are provided on the inner side of the upper clamp 1, upper clamp 2, lower clamp 3, and lower clamp 4. The insert blocks 62 are inserted into the inner wall of the slots 63. Anti-slip grooves are provided on the inner side of the anti-slip pads. The anti-slip pads are made of rubber.

[0025] In this embodiment: After installation, the anti-slip pad can contact the pipe fitting and be squeezed, thereby improving the overall stability and anti-slip properties. At the same time, if the anti-slip pad is damaged, the insert 62 can be removed from the slot 63 to achieve the replacement operation.

[0026] Working principle: When there is a gap between the pipe fittings to be connected, and an adjustment device is needed, the adjusting screw 55 can be rotated. The adjusting screw 55 can rotate in the hollow seat 54. Then, the adjusting screw 55, together with the hollow seat 54, can control the slider 52 and the movable ring 53 to move in the sliding cavity 59 on the surface of the extension ring 51. When the supporting slide rod 58 moves in the hollow sleeve rod 57, the gap between the upper clamp 1 and the upper clamp 2, as well as the gap between the lower clamp 3 and the lower clamp 4, can be adjusted. Then, the upper clamp 1... 1. Attach the upper clamp 2 and the lower clamp 3 and the lower clamp 4 to the pipe fitting. Then, use the locking bolt 7 to lock the upper clamp 1 and the lower clamp 3 and the upper clamp 2 and the lower clamp 4 to complete the overall connection. After clamping, the anti-slip pad can contact the pipe fitting and be squeezed. The anti-slip pad deforms and fits tightly with the pipe fitting to achieve a seal, thereby improving the overall stability and anti-slip performance. In addition, when the anti-slip pad is damaged after long-term use, the insert 62 can be removed from the slot 63 to remove the anti-slip pad for replacement.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
