Description

Technical Field

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

[0002] As a pipe connection technology, clamps have gradually revealed many technical bottlenecks in their traditional design and use methods over a long period of practice, especially in terms of installation process, sealing performance and structural adaptability.

[0003] Specifically, if the pipe is not perfectly centered after the gasket is inserted, the entire structure needs to be disassembled and reinstalled, resulting in wasted time. Statistics show that the rework rate due to alignment errors in industrial sites is as high as 15%. Assembly is also difficult. The current assembly method involves first fitting the clamp onto one end of the pre-connected pipe, then inserting the gaskets into the inside of the clamp, then inserting the flared end into the gasket inside the clamp, and finally locking the clamp. This fixed sequence is required to complete the clamp installation, making the process cumbersome, demanding high skill from workers, and difficult to assemble. Furthermore, ensuring a proper seal after assembly is challenging.

[0004] Therefore, an integrated clamp is still needed to solve the above problems. Utility Model Content

[0005] This utility model provides an integrated clamp to solve the above problems.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An integrated clamp, comprising:

[0008] A retaining ring, wherein the retaining ring has an openable opening and a limiting groove is formed on the inner side of the retaining ring, the limiting groove is used to connect two pipes, at least one of the pipes having a flared end, and the retaining ring is divided into opposite sides in the axial direction, which are respectively used to connect two matching pipe ends.

[0009] A washer is integrated into one side of the retaining ring and elastically clamps the outer wall of the pipe end, so that the pipe end is inside the retaining ring. The arc edge of the washer has alternately distributed first and second connecting parts, which are supported on different sides of the retaining ring, so that the washer is snapped onto one side of the retaining ring. Furthermore, the arc edge of the washer also has an elastic clamping member for clamping the outer wall of the pipe. During assembly, the pipe end is aligned with the washer and located inside the retaining ring and coaxially arranged with the retaining ring.

[0010] When the retaining ring closes its opening, the retaining ring clamps the end of the pipe in sections using washers.

[0011] In one embodiment, at least one limiting portion is formed on the elastic clamping member, the length of the first connecting portion is greater than the length of the second connecting portion, the first connecting portion is hooked onto the outer annular surface of the retaining ring, and the top end of the second connecting portion abuts against the inner annular surface of the retaining ring to prevent the washer from moving along the axial direction of the retaining ring.

[0012] The limiting part and the elastic clamping part are integrally formed. The limiting part has a connecting guide surface and a blocking surface. The guide surface is used to guide the pipe edge of the horn tube to slide in and be offset to the position of contact with the gasket. The blocking surface is used to prevent the edge of the horn tube from separating from the surface of the gasket.

[0013] In one embodiment, at least one side of the first connecting portion is further provided with an abutment, the extending direction of which intersects the extending direction of the first connecting portion, and the abutment has a protrusion for abutting the outer curved surface of the horn tube.

[0014] In one embodiment, the abutment is a branch integrally formed on the first connecting portion at a V-shaped angle, the V-shaped angle ranging from 30 to 120 degrees.

[0015] In one embodiment, a connector extending outward toward the circlip is formed at the opening of the circlip, and a limiting flange for the end of a locking bolt is formed on the connector. When the bolt is tightened, the bolt is located inside the flange.

[0016] In one embodiment, the gasket is generally funnel-shaped, and a seal for mating with a pipe is formed on the annular surface of the gasket.

[0017] In one embodiment, the limiting groove is a V-shaped groove.

[0018] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0019] The system uses an integrable gasket and retainer. Before connection, the gasket can be integrated into the inside of the retainer. The retainer is then pre-tightened to initially secure the gasket and retainer. The flared end of the pipe is then inserted into the gasket and positioned within the elastic retainer on the gasket. The pipe is inserted flexibly, and as the retainer closes, its inner diameter gradually decreases. The elastic retainer moves linearly and remains firmly against the outer wall of the flared pipe. This provides both radial force and a force perpendicular to the radial direction, ensuring the flared pipe fits snugly against the gasket. The tight fit of the gasket within the retainer maintains a high level of sealing between the flared pipe, gasket, and retainer. Attached Figure Description

[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0028] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0029] Reference Figure 1-6 This utility model provides an integrated clamp, including: a retaining ring 1 and a washer 2. The retaining ring 1 and the washer 2 can be formed by stamping or forging, respectively, and are not limited thereto.

[0030] The retaining ring 1 has an openable opening, and a limiting groove 11 is formed on the inner side of the retaining ring 1. The limiting groove 11 is, for example, a V-shaped groove. The limiting groove 11 is used to connect two pipes, at least one of which has a flared end. The retaining ring 1 is divided into two opposite sides in the axial direction, which are used to connect two matching pipe ends respectively. The flared end and the other pipe end need to be matched in size.

[0031] The washer 2 can be integrated into one side of the retaining ring 1 and elastically clamps the outer wall of the pipe end, so that the pipe end is inside the retaining ring 1. The arc edge of the washer 2 has alternating first connecting parts 21 and second connecting parts 22, which are respectively supported on different sides of the retaining ring 1, so that the washer 2 is clamped on one side of the retaining ring 1. Furthermore, the arc edge of the washer 2 also has an elastic clamping member 23 for clamping the outer wall of the pipe. During assembly, the pipe end is clamped to the washer 2 and located inside the retaining ring 1 and coaxially arranged with the retaining ring 1. During connection, washer 2 can be hooked onto one side of retaining ring 1, so that the first connecting part 21 and the second connecting part 22 abut against the inner and outer sides of retaining ring 1 respectively. The connecting part on the outer side has an extension that overlaps the outer annular surface of retaining ring 1, and the supporting part on the inner side abuts against the inner annular and curved sidewall of retaining ring 1. This prevents washer 2 from shifting position after being connected to one side of retaining ring 1 and allows it to move relative to retaining ring 1 along its axis. During installation, washer 2 can be inserted into the opening on one side along the axis of retaining ring 1. Then, the second connecting part 22 will be gradually squeezed, causing it to rotate at a certain angle relative to the root. Finally, it will abut against the inner wall of retaining ring 1 after being offset. The adjacent first connecting part 21 overlaps the outer edge of retaining ring 1. It is not necessary to pre-place washer 2 on the inner side of retaining ring 1 according to complicated assembly steps and procedures.

[0032] When the retaining ring 1 tightens its opening and contracts, the retaining ring 1, through the washer 2, clamps the end of the pipe in segments. As the opening of the retaining ring 1 gradually approaches and the inner diameter decreases, the radial pressure of the retaining ring 1 squeezes the inner washer 2. The first connecting part 21 around the washer 2 will be folded and elastically compressed close to the axis of the retaining ring 1. At this time, the elastic clamping member 23 follows and approaches the outer wall of the horn tube, so that the horn tube not only bears the radial tightening force of the retaining ring 1, but also the tilting force of the elastic clamping member 23 pressing the horn. It can stably seal and clamp the horn tube under various opening sizes and uniform action, and still has a high sealing performance while being easy to assemble.

[0033] In one embodiment, at least one limiting portion 24 is formed on the elastic retaining member 23, and the top sidewall of the elastic retaining member 23 abuts against the sidewall between the inner and outer sides of the retaining ring 1. The bottom end is connected to the washer. The limiting portion 24 is, for example, a protrusion formed on the elastic retaining member 23, wherein the protrusion can be a strip-shaped protrusion, a wave-shaped protrusion, a dot-shaped protrusion, etc., and is not limited here. The top sidewall of the elastic retaining member 23 overlaps the edge sidewall of the retaining ring 1, and when the retaining ring 1 is tightened, the top of the elastic saturation member on the low-pressure inner side is inclined towards a position close to the axis.

[0034] The length of the first connecting portion 21 is greater than the length of the second connecting portion 22. The first connecting portion 21 is attached to the outer annular surface of the retaining ring 1, and the top end of the second connecting portion 22 abuts against the inner annular surface of the retaining ring 1 to prevent the washer 2 from moving along the axial direction of the retaining ring 1. The first connecting portion 21 is used to bypass the retaining ring 1 and finally hang on the outer wall of the retaining ring 1, while the top end of the second connecting portion 22 abuts against the inner wall of the retaining ring 1 to prevent the washer 2 from falling off the retaining ring 1.

[0035] The limiting part 24 and the elastic clamping part 23 are integrally formed and can be manufactured by bending sheet metal. The limiting part 24 has a connecting guide surface 241 and a blocking surface 242, wherein the guide surface 241 and the blocking surface 242 can be two different arcs in cross-section, and the arc of the blocking surface 242 is smaller than that of the blocking surface 242. The guide surface 241 is used to guide the edge of the horn tube to slide in and offset to the position of contact with the washer 2, and the blocking surface 242 is used to prevent the edge of the horn tube from separating from the surface of the washer 2. During assembly, the edge sidewall of the horn tube with the maximum diameter can slide smoothly along the guide surface 241, and will also push the elastic saturation part to expand outward away from the axis along the smooth surface, so that the horn tube is finally inserted into the bottom of the blocking surface 242 and cooperates with the main body of the washer 2 to elastically lock the horn tube, and can stably clamp the washer 2 and the horn tube connected to the washer 2 in multiple open and closed positions.

[0036] Preferably, at least one side of the first connecting portion 21 is further provided with an abutment member 25, the extension direction of which intersects with the extension direction of the first connecting portion 21, and the abutment member 25 has a protrusion for abutting the outer curved surface of the horn tube. The abutment member 25 may be a sheet-like extension formed at the middle position of the first connecting portion 21. The first connecting portion 21 has two functions: first, it is to be attached to the annular outer wall of the retaining ring 1; second, it is to abut against the outer wall of the horn tube. It can cooperate with the elastic clamping member 23 to evenly distribute the abutment against the horn tube, so that the horn tube can be fixed in multiple segments. This facilitates installation and ensures that the washer 2 always drives the horn tube to be stably and sealed inside the retaining ring 1 under various opening sizes, thus ensuring a high degree of sealing.

[0037] Preferably, the abutment 25 is a branch integrally formed on the first connecting portion 21 with a V-shaped angle, the V-shaped angle ranging from 30 to 120 degrees. The abutment 25 can be formed separately on both sides of the first connecting portion 21 as a support portion. When the abutment 25 gradually approaches and squeezes the horn tube under the constriction of the opening of the retaining ring 1, the abutment 25 will gradually open, avoiding the concentration of elastic stress at one position on the horn tube. Furthermore, the V-shaped angle can stably support the washer 2, ensuring that the elastic force remains effective after elastic expansion, thus improving the overall sealing performance of the clamp.

[0038] Preferably, the opening of the retaining ring 1 has a connecting member 3 extending outward from the retaining ring 1. The connecting member 3 has a limiting flange 31 at the end of the locking bolt. When the bolt is tightened, the bolt is located inside the flange. The limiting flange 3141 can be formed by stamping. When the connecting bolt passes through and is tightened to the final preset torque, the sidewall of the bolt and the limiting flange 3141 fit together, preventing the bolt or nut from rotating. This prevents the bolt from loosening or even falling off during operation.

[0039] Preferably, the gasket 2 is generally funnel-shaped, and a sealing element 4 for connecting with the pipe is formed on the annular surface of the gasket 2. The sealing element 4 is, for example, a silicone ring or a rubber ring. During operation, the rubber ring or silicone ring can seal the inner wall of the funnel tube, so that the gas transmitted by the funnel tube can be stably and tightly transmitted from one side of the pipe to the inside of the straight pipe on the other side, achieving high-efficiency gas sealing transmission.

[0040] Preferably, the limiting groove 11 is a V-shaped groove.

[0041] It should be noted that, referring to Figure 1 and Figure 3 , Figure 1 The image shown is an embodiment of this utility model. Figure 3 This is a second embodiment of the present invention. The difference lies in the fact that after the top of the elastic clamping member 23 extends out, one has a bending hooking function, while the other does not.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
