Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp. Background Art

[0002] The clamp is a connection device for connecting grooved pipes, valves and pipeline accessories, and is used to tighten the connection between quick connectors.

[0003] When the clamp is used in the engine exhaust system, such clamp is usually fixed with a bolt and a sleeve. The bolt is inserted into the clamp through the sleeve to complete the locking of the clamp, wherein the sleeve can guide and fix the bolt. However, during the above-mentioned installation process, the sleeve needs to be manually kept parallel on both sides of the clamp, and then the sleeve is vertically placed in the mounting hole of the clamp to align it. Otherwise, the bolt may bend. The vertical centering installation process of the above-mentioned sleeve makes the overall assembly process of the clamp more cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The utility model discloses a clamp, which is used for simplifying the installation process of the clamp and reducing the occurrence of bolt bending.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0012] In some embodiments, the first guide surface is protruding toward the first clamp body to form a spherical surface, and the second guide surface is concave toward the first clamp body to form a surface matching the spherical surface.

[0013] In some embodiments, the spherical radius of the second guide surface is greater than the spherical radius of the first guide surface.

[0014] In some embodiments, the clamp further includes a rotating assembly, and the rotating assembly is used to rotationally connect the first clamp body and the second clamp body;

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0029] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a clamp, comprising: a first clamp body 1, a second clamp body 2, a rotating assembly and a locking assembly;

[0030] The rotating assembly and the locking assembly are respectively arranged on two sides of the first clamp body 1 and the second clamp body 2 that are relatively far away from each other. The first clamp body 1 and the second clamp body 2 are rotatably connected through the rotating assembly, and the first clamp body 1 and the second clamp body 2 are locked through the locking assembly.

[0031] The end of the first clamp body 1 is provided with an avoidance hole 10, and the end of the second clamp body 2 is provided with a connection hole;

[0032] The locking assembly includes a locking member 8 and a sleeve 6. The locking member 8 sequentially passes through the sleeve 6 and the avoidance hole 10 and is connected to the connecting hole, and is used to fix the first clamp body 1 and the second clamp body 2. The size of the avoidance hole 10 is larger than that of the locking member 8.

[0033] A first guide surface 9 is formed on the side of the sleeve 6 facing the first clamp body 1 , and a second guide surface 11 matching the first guide surface 9 is formed on the first clamp body 1 for adjusting the sleeve 6 to center the sleeve 6 , the avoidance hole 10 and the connecting hole.

[0034] The present application provides a first guide surface 9 on one side of the sleeve 6, and the opening direction of the first guide surface 9 is away from the first clamp body 1. When the sleeve 6 contacts the first clamp body 1, the first guide surface 9 contacts the first clamp body 1 first. At the same time, the first clamp body 1 in the present application is also provided with an avoidance hole 10 that cooperates with the first guide surface 9, so that the sleeve 6 can be vertically perpendicular to the first clamp body 1. When the first clamp body 1 and the second clamp body 2 are installed, the first clamp 1 and the second clamp body 2 are first rotated through the rotating assembly to complete the splicing process of the first clamp body 1 and the second clamp body 2. At this time, the sleeve 6 can easily cooperate with the avoidance hole 10 on the basis of the first guide surface 9, so that the sleeve 6 and the avoidance hole are in the same straight line, so that the sleeve 6 completes the guidance of the locking assembly, further avoiding the occurrence of bending of the locking assembly.

[0035] In one possible implementation, the first guide surface 9 protrudes toward one side of the first clamp body 1 to form a spherical surface, and the second guide surface 11 is recessed toward one side of the first clamp body 1 to form a surface that cooperates with the spherical surface. In the above structure, when the sleeve 6 is installed at the position of the avoidance hole 10, the first guide surface 9 and the second guide surface 11 are tangent to each other at this time, so that the sleeve 6 can be placed vertically relative to the first clamp body 1, which is convenient for guiding the locking member 8.

[0036] In a possible implementation, the spherical radius of the second guide surface 11 is greater than the spherical radius of the first guide surface 1 , thereby facilitating cooperation with the first guide surface 1 .

[0037] For a possible implementation, see Figure 1 , Figure 2 The rotating assembly includes a connecting plate 3, a first pin shaft 4 and a second pin shaft 5. The two ends of the connecting plate 3 that are far away from each other are respectively provided with a first pin shaft hole and a second pin shaft hole. The first pin shaft 4 is arranged inside the first pin shaft hole and is transmission-connected to the first clamp body 1. The second pin shaft 5 is arranged inside the second pin shaft hole and is transmission-connected to the second clamp body 2. In the above structure, the present application adds the first pin shaft 4 and the second pin shaft 5, so that the first clamp body 1 and the second clamp body 2 can both rotate relative to the connecting plate 3, and when the first clamp body 1 and the second clamp body 2 are not in a working state, the first clamp body 1 and the second clamp body 2 will not be separated, thereby ensuring the integrity of the present application. At the same time, the present application effectively improves the convenience of using the clamp by rotating the first clamp body 1 and the second clamp body 2.

[0038] In a possible implementation, the first pin shaft 4 and the connecting plate 3 are clearance-fitted, and the first pin 4 and the first clamp body 1 are interference-fitted;

[0039] The second pin shaft 5 and the connecting plate 3 are clearance-fitted, and the second pin shaft 5 and the second clamp body 2 are interference-fitted.

[0040] The first pin shaft 4 and the second pin shaft 5 in the present application are both clearance-matched with the connecting plate 3, so that the first pin shaft 4 and the second pin shaft 5 can both rotate relative to the connecting plate 3, and the first pin shaft 4 and the first clamp body 1 are installed with interference fit, and the second pin shaft 5 and the second clamp body 2 are installed with interference fit, which ensures that the first clamp body 1 and the second clamp body 2 can rotate relative to the connecting plate 3. However, it is worth noting that the first pin shaft 4 and the second pin shaft 5 can also be installed with the first clamp body 1 and the second clamp body 2 by other methods, such as welding, integral casting, etc., and this application does not make specific limitations on this.

[0041] In one possible implementation (not shown in the figure), the rotating assembly includes a rotating shaft, which passes through the first clamp body 1 and the second clamp body 2 in sequence, and is rotatably connected to the first clamp body 1 and the second clamp body 2. The rotating assembly in the present application can also be a single rotating shaft, which passes through the first clamp body 1 and the second clamp body 2 in sequence, so that the first clamp body 1 and the second clamp body 2 are rotatably connected, thereby reducing the volume of the clamp structure, meeting the requirements for use in a compact engine exhaust system, while ensuring that the fixing function of the clamp is not affected.

[0042] For a possible implementation, see Figure 2 The axes of the first pin shaft hole and the second pin shaft hole are parallel. In the present application, the first pin shaft hole and the second pin shaft hole are aligned to ensure that the locking member 8 will not bend or fold when locking the first clamp body 1 and the second clamp body 2. Based on the above design, the present application can extend the service life of the locking member 8 on the one hand, and ensure the locking effect of the locking member 8 after being locked on the other hand.

[0043] In one possible implementation, the locking member 8 includes a bolt, the connecting hole is a threaded hole, the axis of the connecting hole coincides with the axis of the avoidance hole 10, and the bolt is threadedly connected to the connecting hole. In the above structure, the connecting hole is used to be threadedly connected with the bolt, thereby locking the first clamp body 1 and the second clamp body 2 to complete the locking of the entire clamp, and the axis of the connecting hole coincides with the axis of the avoidance hole 10, which can ensure the normal locking of the locking member 8.

[0044] For a possible implementation, see Figure 2 The clamp also includes a seal 7, which is arranged between the locking member 8 and the sleeve 6. In the above structure, the seal 7 is used to seal the gap between the locking member 8 and the sleeve 6, ensuring that impurities and water vapor in the external environment will not enter the gap between the avoidance hole 10 and the threaded hole, thereby extending the overall service life of the clamp of the present application.

[0045] In one possible implementation, the seal 7 includes a gasket. The present application seals the gap between the locking member 8 and the clamp by adding the gasket, thereby further improving the overall airtightness of the present application.

[0046] It is worth noting that the locking member 8 in the present application is not limited to bolts, and other components that are locked in pairs also fall within the scope of protection of the present application, and the present application does not make specific limitations on this.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
