Description

Technical field

[0001] The present application relates to the technical field of clamps, and in particular to a clamp. [Background Technology]

[0002] The clamp is used to fix two or more structural parts with chucks together. It is usually made of metal material and has a certain degree of elasticity. During assembly, the chuck of the structural part is placed in the middle of the clamp. At this time, tightening the clamp can make the clamp tightly pressed against the two structural parts with chucks. After tightening, the clamp is then locked at one end by fasteners such as nuts and bolts to complete the connection process of the structural parts.

[0003] In the process of implementing this application, the inventors discovered that the prior art has at least the following technical problems:

[0004] First, the structural strength of the bolt connection of the clamp is insufficient. During the tightening process of the bolts, stress concentration is likely to occur at the bolt connection, resulting in excessive local stress, which can cause fracture, or the clamp connection can be deformed and stretched, causing the clamp to fail. Secondly, during the use of the clamp, due to vibration or other reasons, the bolts are likely to slip off the bolt connection, affecting the connection reliability of the clamp. [Utility Model Content]

[0005] In view of this, the present application provides a clamp that can improve the clamp's anti-deformation ability and effectively prevent the connection component from slipping by changing the connection structure between the first clamp body and the second clamp body.

[0009] The second clamp body is provided with a third connecting end and a fourth connecting end. The third connecting end is rotatably connected to the first connecting end. An end of the first connecting member away from the abutting member is rotatably connected to the fourth connecting end.

[0012] The clamp also includes a second connecting member. When the first connecting member of the connecting assembly is installed to the first mounting position and the second mounting position, the abutting member abuts against the reinforcing portion, the second connecting member connects the second connecting hole and the third connecting hole, and the connecting assembly applies a force to the reinforcing portion to make the first clamp body and the second clamp body move relative to each other.

[0013] In some embodiments, the first connecting member is provided with a first threaded structure, and the abutting member is provided with a second threaded structure. The first connecting member and the abutting member are engaged with each other through the first threaded structure and the second threaded structure, so that the abutting member can move axially along the first connecting member.

[0014] In some embodiments, the first connecting end is provided with a fourth connecting hole, and the third connecting end is provided with a fifth connecting hole;

[0015] The clamp further includes a third connecting member, and the first connecting end and the third connecting end are rotatably connected through the cooperation of the fourth connecting hole, the third connecting member, and the fifth connecting hole.

[0016] In some embodiments, the second clamp body is provided with a reinforcement protrusion, and the reinforcement protrusion is arranged around the fifth connecting hole.

[0017] In some embodiments, the second connecting member and the third connecting member are rivets, the fourth connecting hole of the first connecting end and the fifth connecting hole of the third connecting end are riveted through the third connecting member, and the second connecting hole of the first connecting member and the third connecting hole of the fourth connecting end are riveted through the first connecting member.

[0018] In some embodiments, the reinforcement portion is formed by being recessed from an end portion of the first installation position, and a cross-sectional shape of the reinforcement portion is U-shaped.

[0019] In some embodiments, the clamp further includes a handle, which is disposed at one end of the abutment away from the first connecting member and is used to apply a force to push the abutment to move axially along the first connecting member to enable the first clamp body and the second clamp body to move relative to each other.

[0020] In some embodiments, the handle and the abutment member are an integrally formed structure.

[0021] In some embodiments, the first clamp body and the second clamp body are arc-shaped structures, and a chuck mounting position is formed between the first clamp body and the second clamp body.

[0022] By adopting the above technical solution, this application has at least the following beneficial effects:

[0023] The clamp provided in the present application is provided with a reinforcement portion and a limiting protrusion at the second connection end. The reinforcement portion can enhance the strength of the first installation position, so that after the connecting component is installed to the first installation position and tightened, the second connection end is not easily stretched open, and the second connection end has better deformation resistance. At the same time, the limiting protrusion is arranged on one side of the second connection end along the installation direction of the connecting component, and then when the connecting component is installed to the first installation position, the limiting protrusion can prevent the connecting component from slipping from the first installation position, thereby improving the connection stability of the clamp.

[0040] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments.

The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0044] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0045] The clamp is used to fix two or more structural parts with chucks together. It is usually made of metal material and has a certain degree of elasticity. During assembly, the chuck of the structural part is placed in the middle of the clamp. At this time, tightening the clamp can make the clamp tightly pressed against the two structural parts with chucks. After tightening, the clamp is then locked at one end by fasteners such as nuts and bolts to complete the connection process of the structural parts.

[0046] In the process of implementing this application, the inventors discovered that the prior art has at least the following technical problems:

[0047] First, the structural strength of the bolt connection of the clamp is insufficient. During the tightening process of the bolts, stress concentration is likely to occur at the bolt connection, resulting in excessive local stress, which can cause fracture, or the clamp connection can be deformed and stretched, causing the clamp to fail. Secondly, during the use of the clamp, due to vibration or other reasons, the bolts are likely to slip off the bolt connection, affecting the connection reliability of the clamp.

[0048] In view of this, this application provides a clamp, please refer to Figures 1 to 3 , the clamp includes:

[0049] The connecting assembly 1 includes an abutting member 11 and a first connecting member 12;

[0050] The first clamp body 2 has a first connecting end 21 and a second connecting end 22. The second connecting end 22 has a first mounting position and a reinforcement portion 223. The reinforcement portion 223 surrounds a portion of the end disposed at the first mounting position. The reinforcement portion 223 has a first connecting hole 2231. The diameter of at least a portion of the abutting member 11 is larger than the diameter of the first connecting hole 2231, and the diameter of at least a portion of the first connecting member 12 is smaller than the diameter of the first connecting hole 2231. The first mounting position has a limiting protrusion 224. The distance between adjacent limiting protrusions 224 is smaller than the width of the abutting portion.

[0051] The second clamp body 3 is provided with a third connecting end 31 and a fourth connecting end 32 . The third connecting end 31 is rotatably connected to the first connecting end 21 . An end of the first connecting member 12 away from the abutting member 11 is rotatably connected to the fourth connecting end 32 .

[0052] In the above scheme, the clamp provided in the present application is provided with a reinforcement portion 223 and a limiting protrusion 224 at the second connection end 22. The reinforcement portion 223 can enhance the strength of the first installation position, so that after the connecting component 1 is installed to the first installation position and tightened, the second connection end 22 is not easily stretched open, and the second connection end 22 has better deformation resistance; at the same time, the limiting protrusion 224 is arranged on one side of the second connection end 22 along the installation direction of the connecting component 1, and then when the connecting component 1 is installed to the first installation position, the limiting protrusion 224 can prevent the connecting component 1 from slipping from the first installation position, thereby improving the connection stability of the clamp.

[0053] In some embodiments, the first clamp body 2 and the second clamp body 3 are arc-shaped structures, and a chuck mounting position is formed between the first clamp body 2 and the second clamp body 3, and the chuck mounting position is approximately circular or circular. It is understandable that the chuck of a structural member is usually a circular or approximately circular structure. Therefore, the first clamp body 2 and the second clamp body 3 are designed to be arc-shaped to better fit the shape of the chuck and achieve a close fit to the outer periphery of the chuck. The arc-shaped design enables the first clamp body 2 and the second clamp body 3 to evenly apply force to the chuck during the tightening process, thereby improving the sealing reliability of the chuck and avoiding chuck leakage caused by uneven local force on the chuck.

[0054] In some embodiments, the first clamp body 2 has a first connection end 21 and a second connection end 22 at its ends, and the second clamp body 3 has a third connection end 31 and a fourth connection end 32 at its ends. The first connection end 21 and the third connection end 31 are rotatably connected. It is understood that after the first connection end 21 and the third connection end 31 are rotatably connected, the size of the chuck mounting position can be adjusted by rotating the first clamp body 2, thereby facilitating the installation of the chuck. Specifically, the clamp further includes a third connecting member 5. The first connection end 21 defines a fourth connection hole 211, and the third connection end 31 defines a fifth connection hole 311. When the first connection end 21 is connected to the third connection end 31, the first connection end 21 is received within the third connection end 31, and the fourth connection hole 211 and the fifth connection hole 311 are coaxially arranged. In this case, the first connection end 21 and the third connection end 31 are connected through the fourth connection hole 211, the third connection member 5, and the fifth connection hole 311. The type of the third connection member 5 can be selected according to actual needs, such as a pin, a rivet, or a screw, and is not limited here. Preferably, the third connecting member 5 used in the present application is a rivet, and the fourth connecting hole 211 of the first connecting end 21 and the fifth connecting hole 311 of the third connecting end 31 are riveted through the third connecting member 5 .

[0055] It should be noted that when the third connector 5 is riveted, a hydraulic press or other riveting equipment is used. This equipment exerts a significant stress on the fifth connection hole 311 during the riveting process, which can easily cause microcracks to form around the fifth connection hole 311 of the third connection end 31. During long-term operation of the structural component, vibration can easily cause the cracks to expand, ultimately damaging the clamp and affecting the clamp connection effect. Therefore, the second clamp body 3 is provided with a reinforcing protrusion 33, which is arranged around the fifth connection hole 311. It can be understood that the provision of the reinforcing protrusion 33 can serve the purpose of structural reinforcement and effectively disperse the stress impact of the third connector 5 during the riveting process, thereby extending the service life of the clamp. This application does not limit the width and height of the reinforcing protrusion 33, and the width and height of the reinforcing protrusion 33 can be selected based on the size of the fifth connection hole 311, the specifications of the riveting equipment, and the size of the third connector 5.

[0056] In some embodiments, the second connection end 22 of the first clamp body 2 and the fourth connection end 32 of the second clamp body 3 are used to install the connection assembly 1, and the connection assembly 1 is used to apply force to the first clamp body 2 to lock the clamp.

[0057] The connecting assembly 1 includes an abutment 11 and a first connecting member 12. The end of the first connecting member 12 away from the abutment 11 is provided with a second connecting hole 121, and the abutment 11 can move along the axial direction of the first connecting member 12. Specifically, the first connecting member 12 is provided with a first threaded structure, and the abutment 11 is provided with a second threaded structure. The first connecting member 12 and the abutment 11 are engaged with each other through the first threaded structure and the second threaded structure. At the same time, the clamp also includes a handle 111. The handle 111 is provided at the end of the abutment 11 away from the first connecting member 12. The handle 111 and the abutment 11 are an integrally formed structure. The handle 111 is used to apply a force to push the abutment 11 to move along the axial direction of the first connecting member 12. It can be understood that during the connection process of the clamp, rotating the handle 111 can drive the abutment 11 to rotate, thereby causing the first clamp body 2 and the second clamp body 3 to move relative to each other.

[0058] It should be noted that the relative movement distance between the abutment member 11 and the first connecting member 12 is relatively large. To prevent the movement of the abutment member 11 from being affected, a through hole is provided in the abutment member 11 along the axial direction, and the handle 111 is a hollow structure. It is understood that with the provision of the through hole and the hollow structure, when the abutment member 11 moves along the axial direction of the first connecting member 12, at least a portion of the first connecting member 12 can pass through the through hole and enter the hollow structure, allowing the abutment member 11 to continue to move.

[0059] The second connection end 22 of the first clamp body 2 extends to form a third extension portion 221, a fourth extension portion 222, and a reinforcement portion 223. The third extension portion 221 and the fourth extension portion 222 are arranged perpendicular to the axial direction of the first connector 12 and opposite each other, forming a first mounting position therebetween. The projection of the first mounting position along the axial direction of the first connector 12 is U-shaped. The reinforcement portion 223 surrounds the end of the first mounting position and is recessed from the end of the first mounting position. The cross-section of the reinforcement portion 223 is a double U-shape. As can be understood, the double U-shape structure can enhance the structural strength of the first mounting position, making it difficult for the third extension portion 221 and the fourth extension portion 222 to be stretched apart during the clamp tightening process.

[0060] The reinforcement portion 223 is provided with a first connection hole 2231. The diameter of at least a portion of the abutment member 11 is larger than the diameter of the first connection hole 2231, and the diameter of the first connection member 12 is smaller than the diameter of the first connection hole 2231. It is understood that the aperture of the first connection hole 2231 is limited to the above conditions. When the connecting assembly 1 is installed, the first connection member 12 can pass through the first connection hole 2231 of the reinforcement portion 223, and the bottom of the abutment member 11 abuts the top surface of the reinforcement portion 223. When the abutment member 11 is rotated, the abutment member 11 can apply a force to the reinforcement portion 223, thereby pushing the first clamp body 2 to move in a direction closer to the second clamp body 3.

[0061] The third extension 221 and the fourth extension 222 are provided with limiting protrusions 224. The limiting protrusions 224 are integrally formed with the third and fourth extensions 221, 222, and the spacing between adjacent limiting protrusions 224 is less than the width of the abutment portion. It will be appreciated that with the limiting protrusions 224, when the abutment member 11 of the connecting assembly 1 deviates from the reinforcing portion 223 due to vibration, the limiting protrusions 224 can restrict the further movement of the abutment member 11, thereby preventing the abutment member 11 from slipping.

[0062] The fourth connection end 32 extends to form a first extension portion 321 and a second extension portion 322. The first extension portion 321 and the second extension portion 322 are arranged opposite to each other perpendicular to the axial direction of the first connection member 12, and a second mounting position is formed therebetween. The projection of the second mounting position along the axial direction of the first connection member 12 is "U"-shaped.

[0063] A third connecting hole 323 is provided in a direction opposite to the first extension portion 321 and the second extension portion 322, and the clamp further includes a second connecting member 4. When the first connecting member 12 of the connecting assembly 1 is installed in the second mounting position, the second connecting hole 121 and the third connecting hole 323 are coaxially arranged, and the second connecting member 4 connects the second connecting hole 121 and the third connecting hole 323. The type of second connecting member 4 can be selected according to actual needs, such as a pin, rivet, or screw, etc., and is not limited here. Preferably, the second connecting member 4 used in this application is a rivet, and the second connecting hole 121 of the first connecting member 12 and the third connecting hole 323 of the fourth connecting end 32 are riveted together through the first connecting member 12.

[0064] During the actual assembly process, a sealing ring is placed between the structural parts with the chuck to form an assembly, and the clamp is put on the connection part of the assembly to ensure that the clamp is positioned correctly; then the handle 111 is turned, and the abutment 11 applies a force to the reinforcement part 223, so that the abutment 11 moves axially along the first connecting part 12, thereby pushing the first clamp body 2 and the second clamp body 3 to move relative to each other, so that the clamp is tightly pressed against the chuck connection.

[0065] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
