[0041] 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.

[0042] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

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.

[0045] 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.

[0046] 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 chucks of adjacent structural parts are placed in the middle of the clamp, and sealing rings are set between adjacent chucks. At this time, tightening the clamp can make the clamp tightly pressed on the two structural parts with chucks. The chuck squeezes the sealing ring to achieve a sealing effect. 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.

[0047] In the process of implementing this application, the inventors discovered that the prior art has at least the following technical problems:

[0048] First, during the installation of the clamp, the positioning of the chuck on the clamp is inaccurate, and the two are prone to installation misalignment; second, during the tightening of the clamp, the groove wall of the clamp exerts uneven force on the chuck, affecting the squeezing effect of the chuck on the sealing ring, and thus affecting the sealing effect of the sealing ring.

[0049] In view of this, this application provides a clamp, please refer to Figures 1 to 4 The clamp includes a connecting assembly 1, a first clamp body 2 and a second clamp body 3. One end of the first clamp body is rotatably connected to one end of the second clamp body. The connecting assembly 1 can apply a force to make the other end of the first clamp body 2 and the other end of the second clamp body 3 move relative to each other. The first clamp body 2 and the second clamp body 3 are provided with a groove, and the groove includes:

[0050] The slot body 41 includes a rectangular slot 411 and a guide slot 412 . The guide slot 412 extends outwardly from the end of the rectangular slot 411 .

[0051] The chamfered portion 42 is formed concavely on the wall surface of the guide groove 412 at the end portions of the first clamp body 2 and the second clamp body 3 .

[0052] In the above scheme, the clamp provided by the present application changes the shape of the groove, and the groove main body 41 includes a rectangular groove 411 and a guide groove 412. The guide groove 412 can guide the chuck structure into the rectangular groove 411. During the tightening process, the parallel walls of the rectangular groove 411 make the force applied by the clamp on the chuck more uniform, thereby improving the compression effect of the chuck on the sealing ring; and, through the setting of the chamfered portion 42, the clamp can better position the sealing ring during the tightening process, and the clamp, chuck and sealing ring are aligned, and the three are not easily misaligned, thereby ensuring that the sealing ring is installed in place and the sealing effect is better after compression.

[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 tight fit on 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] Grooves are provided inside the arc-shaped structures of the first clamp body 2 and the second clamp body 3. The design of the internal grooves enables the clamp to better engage with the chuck of the structural component during installation. Part of the structure of the chuck is embedded in the groove, so that the clamp can squeeze the chuck along the thickness direction of the sealing ring, ensuring that the clamp is not easy to slip off the chuck during the tightening process, and the chuck compresses the sealing ring after being subjected to uniform extrusion force.

[0055] The main groove body 41 is an arc-shaped structure, comprising a rectangular groove 411 and a guide groove 412. The guide groove 412 extends outward at an angle from the end of the rectangular groove 411, resulting in a cross-sectional shape of the main groove 411 that is a combination of a rectangular and a trapezoidal structure. As will be appreciated, when the clamp abuts the chuck, the guide groove 412 guides part of the chuck structure into the rectangular groove 411. During tightening, the parallel walls of the rectangular groove 411 ensure a more uniform extrusion force from the clamp on the chuck, ensuring a more uniform compression force on the sealing ring along its thickness, thus ensuring a more effective compression of the sealing ring.

[0056] In order to improve the positioning effect of the chuck on the clamp, a chamfered portion 42 is provided on the guide groove 412. Specifically, the chamfered portion 42 is recessed and formed on the wall surface of the guide groove 412 at the end of the first clamp body 2 and the second clamp body 3. The width and depth of the chamfered portion 42 are not limited in this application and can be selected according to the size of the sealing ring. It can be understood that the chamfered portions 42 are provided at four positions at the end of the groove of the first clamp body 2 and the second clamp body 3, and the spacing distance between the chamfered portions 42 at both ends is the same along the length and thickness direction of the first clamp body 2 and the second clamp body 3. Furthermore, through the provision of the chamfered portions 42, at least a portion of the chamfered portion 42 abuts against the chuck and the sealing ring during the tightening process of the clamp, which can better position the chuck, align the clamp, chuck and the sealing ring, and prevent the three from being misaligned, thereby ensuring that the sealing ring is installed in place and the sealing effect is better after compression.

[0057] In some embodiments, the groove further includes an abutment protrusion 43, which is disposed at the junction of the rectangular groove 411 and the guide groove 412. The abutment protrusion 43 is located on the inner side of the chamfered portion 42 along the width direction of the first clamp body 2 and the second clamp body 3, and protrudes in the direction of the guide groove 412. It is understood that after the abutment protrusion 43 is provided, when the clamp is installed on the chuck, the abutment protrusion 43 can abut against the chuck, thereby playing a positioning role, limiting the deviation of the chuck, and ensuring the installation accuracy of the chuck on the sealing ring. This application does not limit the width, length, and height of the abutment protrusion 43, and can be selected based on the size of the chuck and the clamp.

[0058] In some embodiments, two ends of the first clamp body 2 are respectively a first connecting end 21 and a second connecting end 22 , and two ends of the second clamp body 3 are respectively a third connecting end 31 and a fourth connecting end 32 .

[0059] The first connection end 21 of the first clamp body 2 and the fourth connection end 32 of the second clamp body 3 are used to install the connection component 1, and the connection component 1 is used to apply force to the first clamp body 2, so that the first clamp body 2 and the second clamp body 3 move relative to each other, thereby locking the clamp.

[0060] 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 first 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, reducing the volume of the chuck mounting position so that the chuck compresses the sealing ring.

[0061] It should be noted that the distance over which the abutting member 11 and the first connecting member 12 move relative to each other is relatively large. To prevent the movement of the abutting member 11 from being affected, a through hole is provided in the abutting member 11 along the axial direction, and the handle 111 is a hollow portion. It is understood that with the provision of the through hole and the hollow portion, when the abutting 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 portion, allowing the abutting member 11 to continue moving.

[0062] The fourth connecting end 32 is provided with a second connecting hole 323 along the width direction of the groove, and the clamp also includes a second connecting member 5. When the first connecting member 12 of the connecting assembly 1 is installed in the second mounting position 321, the first connecting hole 121 and the second connecting hole 323 are coaxially arranged, and the second connecting member 5 connects the first connecting hole 121 and the second connecting hole 323. The type of second connecting member 5 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 5 used in this application is a rivet, and the first connecting hole 121 of the first connecting member 12 and the second connecting hole 323 of the fourth connecting end 32 are riveted together by the second connecting member 5.

[0063] In some embodiments, the first connection end 21 is rotatably connected to the third connection end 31. It is understandable 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 also includes a third connecting member 6. The first connection end 21 is provided with a third connecting hole 211, and the third connection end 31 is provided with a fourth connecting hole 311. When the first connection end 21 is connected to the third connection end 31, the first connection end 21 is accommodated in the third connection end 31, and the third connection hole 211 and the fourth connection hole 311 are coaxially arranged. At this time, the first connection end 21 and the third connection end 31 are connected through the cooperation of the third connection hole 211, the third connection member 6, and the fourth connection hole 311. The type of the third connection member 6 can be selected according to actual needs, such as a pin, a rivet, or a screw, etc., which is not limited here. Preferably, the third connecting member 6 used in the present application is a rivet, and the third connecting hole 211 of the first connecting end 21 and the fourth connecting hole 311 of the third connecting end 31 are riveted through the third connecting member 6 .

[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, 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, and the chuck part enters the rectangular groove 411 from the guide groove 412, and the chamfered part 42 of the groove and the abutment protrusion 43 abut against the chuck, thereby realizing accurate positioning of the clamp, the sealing ring and the chuck, and continuing to apply force 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 are only preferred embodiments 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.
