Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a clamp that is easy to install. Background Art

[0002] A clamp is a commonly used connection device used to connect grooved pipes, valves and pipe accessories. It is usually used to tighten the connection between quick connectors.

[0003] The clamp currently used in small pipes usually includes a gasket body, a sealing ring and a locking piece. The gasket body is an integrally formed R-shaped metal sheet, which has two corresponding abutment sheets, and the abutment sheets are provided with locking through holes for the locking piece to pass through. The locking piece is a matching method of bolts and nuts.

[0004] With regard to the above-mentioned related technologies, when using, the user needs to use one hand to press the two abutment sheets together, and the other hand to pass the locking piece through the locking through hole and turn the nut. After the nut is turned a certain number of times, the pressure on the abutment sheet is released, and then the locking tool is used for the final locking. The above-mentioned locking process requires one hand to insert the bolt and turn the nut, which has high operational requirements. Utility Model Content

[0005] In order to facilitate the installation efficiency of the clamp and the pipe, the present application provides a clamp that is easy to install.

[0006] The present application provides a clamp that is easy to install and adopts the following technical solution:

[0007] A clamp that is easy to install includes a gasket body, an elastic soft pad limitedly installed on the gasket body, and a locking piece. The gasket body has two first abutment pieces and a second abutment piece that correspond to each other and into which the locking piece is inserted. The first abutment piece is provided with a clamping groove, and the second abutment piece is provided with a clamping piece for correspondingly clamping with the clamping groove. When the clamping piece is clamped into the clamping groove, the clamping piece has a tendency to disengage from the clamping groove.

[0008] By adopting the above technical solution, when using the above-mentioned clamp to clamp the pipe, the first abutment piece is pressed toward the second abutment piece, so that the clamping piece is clamped into the clamping groove, and the two abutment pieces are in a close state. The two abutment pieces are pre-positioned by the cooperation of the clamping piece and the clamping groove, so that the installer can use both hands to insert and tighten the bolts, thereby reducing the difficulty of assembly and improving the efficiency of installation. At the same time, after the fixing of the locking piece is released, the clamping piece is removed from the clamping groove as the first abutment piece recovers its deformation, which has good practicality.

[0009] Optionally, the engaging groove is located on a side of the first abutting piece away from the gasket body.

[0010] By adopting the above technical solution, the snap-in groove is arranged at one end of the first abutting piece away from the gasket body, which can reduce the impact on the assembly of the locking member compared to arranging the snap-in groove on both sides of the first abutting piece.

[0011] Optionally, the first abutting piece is provided with the clamping grooves on both sides along the extension direction, and the clamping pieces are arranged in a one-to-one correspondence with the clamping grooves.

[0012] By adopting the above technical solution, another arrangement form of the snap-in grooves is disclosed, in which snap-in grooves are provided on both sides of the first abutment piece. Compared with only providing the snap-in groove on one side of the first abutment piece, the above arrangement method can make the pre-fixing strength of the two abutment pieces more reliable.

[0013] Optionally, the first abutment piece is arranged along the extension direction of one end of the gasket body, and the second abutment piece is arranged in a staggered manner with the extension direction of the other end of the gasket body.

[0014] By adopting the above technical solution, the first abutment plate is arranged along the extension direction of the gasket body, and the extension directions of the second abutment plate and the gasket body are staggered, so that the clamp is R-shaped as a whole, and the second abutment plate has better movement drive. The snap-fit ​​plate is set on the second abutment plate to facilitate the snap-fit ​​plate to detach from the snap-fit ​​groove.

[0015] Optionally, the first abutting piece is provided with limiting pieces on opposite sides of the clamping groove, the limiting pieces are inclined toward the clamping piece, and the two limiting pieces gradually approach each other from the first abutting piece to the second abutting piece.

[0016] By adopting the above technical solution, the two limiting pieces are inclined inwardly toward the engaging piece, so that after the engaging piece is inserted into the two limiting pieces, the limiting piece has a limiting effect on the engaging piece, thereby reducing the probability of the limiting piece detaching from the engaging groove.

[0017] Optionally, a guide surface for guiding the insertion of the engaging piece is provided at the end of the limiting piece.

[0018] By adopting the above technical solution and setting the guide surface, it is convenient for assemblers to insert the clamping piece into the clamping groove, thereby improving the assembly efficiency of the clamp.

[0019] Optionally, the second abutment piece has a yielding notch corresponding to the limiting piece, and the extending direction of the limiting piece and the extending direction of the first abutment piece are staggered and inclined along the limiting piece, and the inclination range of the limiting piece is 5-10°.

[0020] By adopting the above technical solution, when the engaging piece is inserted into the two limiting pieces, the positioning groove is provided for the limiting piece, and the inclined arrangement of the engaging piece can make it more convenient to insert the engaging piece into the engaging groove.

[0021] Optionally, the second abutment piece has a yielding notch corresponding to the limiting piece, and the extending direction of the limiting piece and the extending direction of the first abutment piece are staggered and inclined along the limiting piece, and the inclination range of the limiting piece is 5-10°.

[0022] By adopting the above technical solution, when the engaging piece is inserted into the two limiting pieces, the positioning groove is provided for the limiting piece, and the inclined arrangement of the engaging piece can facilitate the engaging piece to be inserted into the engaging groove.

[0023] Optionally, the elastic soft pad has an embedded groove that is snap-fitted with the gasket body, and the elastic soft pad is provided with abutment lines on a side away from the embedded groove, and the abutment lines are arranged circumferentially at intervals along the axial direction of the gasket body.

[0024] By adopting the above technical solution, the elastic pad is fixed by the embedded groove and the gasket body. The elastic pad can play a buffering role when the clamp is clamped and fixed. At the same time, the setting of the abutting texture can increase the friction between the elastic pad and the pipeline, and reduce the probability of circumferential rotation of the pipeline.

[0025] Optionally, the gasket body is provided with reinforcing ribs along the circumferential direction on the side wall away from the inner hole.

[0026] By adopting the above technical solution, reinforcing ribs are arranged on the gasket body along the circumferential direction, which can limit the rotation direction of the first abutment piece and ensure that the clamping piece can be accurately inserted into the clamping groove.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The present application provides a clamping block and a clamping groove, so that the clamp can be pre-fixed before clamping the pipe, which is convenient for the assembler to perform the locking operation of the locking piece;

[0029] 2. The application provides a limiting piece, which can limit the insertion of the card piece and facilitate the card piece to be detached from the card slot;

[0030] 3. The present application provides a guide surface on the limiting plate to facilitate the insertion of the connecting plate between the two limiting plates to achieve pre-fixation, thereby improving the pre-fixation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] The embodiment of the present application discloses a clamp that is easy to install.

[0037] Embodiment 1:

[0038] Reference Figure 1 , a clamp that is easy to install, includes a gasket body 1, an elastic cushion 2 and a locking member 3. The gasket body 1 is in the shape of a sheet with a U-shaped cross section as a whole, and is made of a metal material such as stainless steel with a certain elastic deformation ability.

[0039] The first abutment sheet 4 and the second abutment sheet 5 are respectively provided at both ends of the gasket body 1. The first abutment sheet 4 and the second abutment sheet 5 are both integrally formed with the gasket body 1. The first abutment sheet 4 is arranged along the extension direction of the end of the gasket body 1. The extension direction of the second abutment sheet 5 and the end of the gasket body 1 are staggered, and the second abutment sheet 5 is deflected as a whole in a direction away from the first abutment sheet 4.

[0040] Combination Figure 2 The gasket body 1, the first abutting piece 4 and the second abutting piece 5 are metal sheets with an R-shaped cross section. The first abutting piece 4 has a clamping groove 41 penetrating the end surfaces on both sides at the end away from the gasket body 1. The clamping groove 41 is a T-shaped opening groove on the surface of the first abutting piece 4.

[0041] The end of the second contact piece 5 has a card piece 51 corresponding to the card slot 41. The card piece 51 is located in the middle of the length direction of the second contact piece 5, and the card piece 51 is tilted toward the first contact piece 4. The tilt range of the card piece 51 is 3-5 degrees.

[0042] The first abutting piece 4 is also provided with a limiting piece 42 at the clamping groove 41. The limiting piece 42 is formed by bending the first abutting piece 4 at opposite sides of the clamping groove 41. The limiting piece 42 is tilted toward the clamping piece 51 as a whole, and the two limiting pieces 42 are tilted inwardly toward each other. The limiting piece 42 has a guide surface 421 at the end facing the second abutting piece 5 for guiding the clamping piece 51 to be inserted.

[0043] The second abutting piece 5 has a clearance slot 52 corresponding to the limiting piece 42 on both sides of the locking piece 51 , so that after the locking piece 51 is inserted, the limiting piece 42 passes through the clearance slot 52 .

[0044] The gasket body 1 is provided with reinforcing ribs 11 along the circumferential direction on the side wall away from the inner hole. The reinforcing ribs 11 are formed integrally with the gasket body 1 and are located in the middle of the outer wall of the gasket body 1.

[0045] When the clamping piece 51 is inserted between the two limiting pieces 42, the clamp is in a P shape as a whole, and the gasket body 1 has a tendency to restore the second abutting piece 5 to its initial state. Therefore, the assembler only needs to move the clamping piece 51 to remove the clamping piece 51 from the clamping groove 41, and the gasket body 1 returns to an R shape, which is convenient for the next locking.

[0046] The elastic pad 2 is connected to the gasket body 1 in a limiting manner. In this embodiment, the elastic pad 2 is made of rubber material, and is in a U-shape as a whole, and has a limiting flange 21 on the side facing away from the U-shaped opening. The setting of the limiting flange 21 forms an embedded groove 22 on the elastic pad 2 that is engaged with the gasket body 1, and the embedded groove 22 is a T-shaped groove.

[0047] In order to improve the clamping effect of the clamp on the pipe, abutment lines 23 are provided on the inner wall of the elastic cushion 2. The abutment lines 23 are evenly spaced along the central axis of the wire clamp body to increase the friction area between the elastic cushion 2 and the pipe, thereby improving the clamping effect.

[0048] The locking member 3 comprises a locking bolt 31 and a locking nut 32, which are threadedly matched with each other. The two abutment plates are provided with locking through holes 43 for the locking bolt 31 to pass through.

[0049] The implementation principle of the clamp that is easy to install in the embodiment of the present application is as follows: when using the clamp, the second abutment piece 5 is rotated so that the clamping piece 51 is inserted between the two limiting pieces 42 to achieve a pre-fixed connection between the first abutment piece 4 and the second abutment piece 5; at this time, the clamp is in a P shape as a whole, and the locking bolt 31 is passed through the two locking through holes and locked by the locking nut 32. When disassembling, the locking bolt 31 is loosened and removed, and the assembler only needs to move the clamping piece 51, and the clamping piece 51 is separated from the clamping groove 41 under the force of the wire clamp body restoring its deformation.

[0050] Embodiment 2:

[0051] Compared with the first embodiment, the present embodiment has the same structure as the clamp structure of the first embodiment except that the arrangement directions of the clamping groove 41 and the clamping piece 51 are different.

[0052] Reference Figure 3The second contact piece 5 is provided with a clamping groove 41, which is arranged at the middle of both sides of the extending direction of the second contact piece 5. The structure of the clamping groove 41 is consistent with that of the embodiment 1, and a limiting piece 42 with the same structure as that of the embodiment 1 is also provided.

[0053] The first abutting piece 4 has a clamping piece 51 corresponding to the two clamping grooves 41, and the structure of the clamping piece 51 is consistent with the structure of the clamping piece 51 of embodiment 1. The arrangement of the two clamping pieces 51 and the clamping grooves 41 can increase the connection strength when the first abutting piece 4 and the second abutting piece 5 are pre-fixed.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
