Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to an anti-slip groove steel clip. Background Art

[0002] The anti-slip groove clamp is a fastener used for pipe connection. It is mainly used to fix and seal the pipe section in the groove pipeline system to ensure the stability and safety of the pipeline system. The groove clamp is usually composed of two semicircular clamps (or clamps), with grooves inside the clamps to match the pre-processed grooves on the pipe. The clamps are fastened together by bolts or buckles to fix and seal the pipe.

[0003] The sealing gasket of the groove clamp is fixed on the groove of the pipe connection by two clamps. During the use of the pipe, due to factors such as temperature changes, cold shrinkage may occur. When the pipe shrinks, the gap between the pipe and the groove clamp will increase, which will cause the original sealing gasket or sealing material to be unable to completely fill these gaps, resulting in a decrease in sealing performance and an increased risk of leakage. At the same time, it will cause the pipe connection to loosen, thereby affecting the stability and safety of the entire pipe system. Utility Model Content

[0004] The utility model aims to solve the problem that when the existing groove steel clamp produces cold shrinkage in the pipeline, the gap between the pipeline and the groove steel clamp will increase, thereby causing the sealing performance to decrease and increasing the risk of leakage, and to propose an anti-slip groove steel clamp.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technology: an anti-slip groove steel clamp, comprising a first clamp plate and a second clamp plate, wherein first connecting seats are provided at both ends of the first clamp plate, second connecting seats are provided at both ends of the second clamp plate, and the first clamp plate and the second clamp plate are detachably connected by connecting bolts, and a plug-in assembly for quick connection of the first clamp plate and the second clamp plate is provided on the second connecting seat, sealing gaskets are provided on the inner side surfaces of the first clamp plate and the second clamp plate, and compensation assemblies are provided on the first clamp plate and the second clamp plate.

[0006] As a further description of the above technical solution: the compensation component includes a mounting tube fixed on the first clamp plate and the second clamp plate, a screw is arranged in the mounting tube, a top is sleeved on one end of the screw close to the sealing gasket, and a handle is arranged on the other end of the screw, and the first clamp plate and the second clamp plate are both provided with holes matching with the screw.

[0007] As a further description of the above technical solution: a rubber pad is arranged at the bottom of the plug, a second spring is arranged inside the plug, and a limiting end abutting against the second spring is arranged at one end of the screw located inside the plug.

[0009] As a further description of the above technical solution: a sealing cover is detachably connected to the installation cylinder via a threaded joint, and an outer side surface of the sealing cover is provided with anti-slip grooves.

[0010] As a further description of the above technical solution: the number of compensation components on the first clamp plate and the second clamp plate is three, and the compensation components are evenly arranged on the first clamp plate and the second clamp plate along their arc surfaces.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] Reference Figure 1-Figure 5 The present embodiment provides an anti-slip groove steel clamp, comprising a first clamp plate 1 and a second clamp plate 2, wherein first connecting seats 3 are provided at both ends of the first clamp plate 1, second connecting seats 4 are provided at both ends of the second clamp plate 2, and the first clamp plate 1 and the second clamp plate 2 are detachably connected by connecting bolts 5, a plug-in assembly 41 for quick connection between the first clamp plate 1 and the second clamp plate 2 is provided on the second connecting seat 4, sealing gaskets 6 are provided on the inner side surfaces of the first clamp plate 1 and the second clamp plate 2, and compensation assemblies 7 are provided on the first clamp plate 1 and the second clamp plate 2.

[0025] In the utility model, when the groove is just clamped for installation, the first clamp plate 1 and the second clamp plate 2 are aligned with the pipe connection, and then the sealing gasket 6 on the first clamp plate 1 and the second clamp plate 2 is aligned with the groove of the pipe connection, the first clamp plate 1 and the second clamp plate 2 are closed, and the plug-in component 41 on the second connecting seat 4 of the second clamp plate 2 cooperates with the first connecting seat 3 of the first clamp plate 1 to achieve preliminary clamping and fixing, and then the operator can free the other hand and focus on the operation of the connecting bolt 5, saving installation time, when the pipeline shrinks due to factors such as temperature, the compensation component 7 is used to compensate for the shrinkage, so that the sealing gasket 6 can fit tightly on the pipeline, reducing or eliminating potential leakage gaps, thereby significantly improving the sealing performance.

[0026] Specifically, Figure 1-Figure 3 As shown, the compensation assembly 7 includes a mounting tube 71 fixed on the first clamp plate 1 and the second clamp plate 2, a screw 72 is arranged in the mounting tube 71, a top head 73 is sleeved on one end of the screw 72 close to the sealing gasket 6, and a handle 74 is arranged on the other end of the screw 72, and a hole 11 matching with the screw 72 is opened on the first clamp plate 1 and the second clamp plate 2.

[0027] Among them, the inner ring and outer ring of the groove clamp are connected through the orifice 11, and the installation cylinder 71 is fixed on the outer ring surface of the first clamp plate 1 and the second clamp plate 2. When the pipeline shrinks due to temperature factors, the screw 72 is turned through the handle 74. The screw 72 moves toward the center of the groove clamp when twisting, thereby squeezing the sealing gasket 6 of the first clamp plate 1 and the second clamp plate 2 through the head 73, and then under the squeezing action of the screw 72, the sealing gasket 6 can compensate for the shrinkage of the pipeline, so that the sealing gasket 6 can fit tightly on the pipeline, reduce or eliminate potential leakage gaps, and thus significantly improve the sealing performance.

[0028] Specifically, Figure 3 and Figure 4 As shown, a rubber pad 731 is provided at the bottom of the top head 73, a second spring 732 is provided inside the top head 73, and a limiting end 721 is provided at one end of the screw rod 72 located inside the top head 73 to abut against the second spring 732. The rubber pad 731 is provided in a hemispherical shape, and when the screw rod 72 pushes the top head 73 to squeeze the sealing pad 6, the rubber pad 731 contacts the sealing pad 6 first, which can protect the sealing pad 6 on the one hand, and on the other hand, the rubber pad 731 cooperates with the second spring 732 for buffering, so that a buffer space can be provided when the sealing pad 6 is pressed, thereby improving the safety of the groove rigid clamping.

[0029] It should be noted that a slot 733 is provided on the inner wall of the top head 73, and a limit strip 722 is provided on the limit end head 721 to match the slot 733. The slot 733 and the limit strip 722 can prevent the top head 73 and the screw rod 72 from rotating, and when the screw rod 72 is rotated to push the top head 73 to move, wear caused by the mutual rotation between the screw rod 72 and the top head 73 can be avoided.

[0030] Specifically, Figure 2 and Figure 3 As shown, the installation cylinder 71 is detachably connected with a sealing cover 76 through a threaded joint 75, and the outer side of the sealing cover 76 is provided with anti-slip grooves. In daily use, the sealing cover 76 is screwed on the outside of the installation cylinder 71 through the threaded joint 75 to prevent foreign matter from entering the inside of the installation cylinder 71. When pipeline shrinkage compensation is required, the sealing cover 76 is screwed off through the threaded joint 75, and then compensation adjustment is performed through the screw 72.

[0031] There are three compensation components 7 on both the first clamp plate 1 and the second clamp plate 2, and the compensation components 7 are evenly arranged along the arc surface of the first clamp plate 1 and the second clamp plate 2. The three compensation components 7 evenly arranged on the first clamp plate 1 and the second clamp plate 2 can work simultaneously and evenly when compensation is required for cold shrinkage of the pipeline, thus avoiding the problem of insufficient compensation or excessive compensation that may exist in a single compensation structure.

[0032] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, the plug-in assembly 41 includes a plug-in plate 411, on which a limit block 413 is arranged through a mounting groove 412, a baffle 414 is arranged at one end of the limit block 413 located inside the mounting groove 412, and a first spring 415 is arranged between the baffle 414 and the inner wall of the mounting groove 412, and a plug-in hole 31 matching with the plug-in plate 411 is opened on the first connecting seat 3.

[0033] Among them, when the groove is just clamped for installation and use, the first clamp plate 1 and the second clamp plate 2 are clamped on the pipe connection, and then the first clamp plate 1 and the second clamp plate 2 are close to each other, and the plug plate 411 of the second connecting seat 4 is aligned with the plug hole 31 of the first connecting seat 3. As the first clamp plate 1 and the second clamp plate 2 continue to close, the plug plate 411 passes through the plug hole 31. During the penetration process, the limit block 413 and the baffle 414 compress the first spring 415 and are squeezed into the installation groove 412. As the first connecting seat 3 and the second connecting seat 4 are fitted together, the top of the plug plate 411 extends out of the plug hole 31, and the limit block 413 pops out and rests on the first connecting seat 3 under the action of the first spring 415, so that it can be clamped and connected first when the groove is just clamped, allowing the operator to use one-handed operation in the early stage of connection, freeing up the other hand, improving the convenience of operation, and saving the overall installation time.

[0034] It should be noted that the limit block 413 is wedge-shaped, the plug plate 411 passes through the first connection seat 3 through the plug hole 31, and the top of the plug plate 411 is located between the first clamp plate 1 and the connecting bolt 5. The wedge-shaped limit block 413 saves more effort when the plug plate 411 is plugged in. When the first clamp plate 1 and the second clamp plate 2 are connected, the plug plate 411 does not need to be manually squeezed when passing through the plug hole 31. It only needs to squeeze the limit block 413 when the first clamp plate 1 and the second clamp plate 2 are disassembled to shrink it in the installation groove 412, so that it can save more effort when the groove is just clamped and installed.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
