U.S. patent No. 11112042B2 discloses a clip which adopts a common V-shaped clip structure and can be clamped on a hump tube through a clamping groove with a V-shaped section. However, the technical staff find that the high-temperature gas flows into the hump pipe in the using process of the exhaust pipe system, so that the hump pipe deforms at high temperature in the long-term using process, and further the hump-shaped bulge structure of the hump pipe deforms, so that the widths of different parts of the hump bulge structure change. The width change that hump uplift structure took place deformation and lead to can extrude the clamp and also take place deformation, causes the V-arrangement groove of clamp still can press from both sides tight hump pipe in certain position, but some positions can't effectually press from both sides tight hump pipe because hump uplift structure's width change, and then lead to hump pipe and other pipe fittings's butt joint poor, then causes other problems of exhaust pipe system.

Detailed Description

The following description of the embodiments of the present utility model will clearly and fully describe the technical aspects of the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.

Example 1

As shown in fig. 1, in combination with fig. 2 and 3, a clip for hump pipe according to the present utility model includes an endless belt 1 and wing portions 3.

Wherein, the end of the hump tube 10 is axially formed with a hump portion 101 around the hump tube 10. The horn tube is matched and butted with the hump tube 10, the horn mouth of the horn tube is matched with the outer side surface of the hump part 101 of the hump tube 10, and the clamp clamps the matched parts of the horn tube and the hump part.

The radial section of the structure enclosed by the ring belt 1 and the wing parts 3 at the two sides along the extending direction of the ring belt 1 is V-shaped or U-shaped. The two ends of the ring belt 1 are provided with lugs 2 for locking the clamp on the hump pipe 10, the two ends of the ring belt 1 are broken and bent into a ring shape, and the ring belt 1 is tightened between the two lugs 2 through a bolt fastener to clamp a pipe fitting; the ears 2 are fixedly connected on the outer ring surface of the end part of the ring belt 1 in a welding or riveting mode. The girdle 1 is sleeved outside the hump 101.

At least four wings 3 are divided into two groups. The two groups of wings 3 are respectively arranged at two sides of the extension direction of the ring belt 1, the wings 3 in each group are distributed at intervals along the extension direction of the ring belt 1, the wings 3 are lapped on the side surface of the hump 101, the wings 3 lapped at two sides of the hump 101 clamp the hump 101, so that the hump 101 is clamped by the two wings 3 at two sides of the ring belt 1, and simultaneously, the hump 101 at different positions on the hump pipe 10 is clamped by the two wings 3 in different pairs. The width of the wing part 3 along the extending direction of the girdle belt 1 is larger than the width of the side surface of the hump part 101 along the extending direction of the girdle belt 1, so that the situation that the wing part 3 is too narrow to clamp the hump part 101 effectively is avoided.

The number of the wing parts 3 in the two sets may be the same or different.

When the number of the two sets of wing parts 3 is the same, in general, the two sets of wing parts 3 are symmetrically disposed on both sides in the extending direction of the circumferential belt 1. However, the two sets of wing parts 3 may be arranged in a staggered manner, so that the wing part 3 on one side and two adjacent wing parts 3 on the other side can clamp two different parts of the hump 101 at the same time. Similarly, when the number of the wing parts 3 in the two groups is different, the two groups of wing parts 3 are arranged in a staggered manner.

Example two

On the basis of the first embodiment, although different positions of the hump 101 are clamped by different pairs of the wing parts 3, it is still difficult to secure the tightness of the clamp clamping the hump tube 10.

In order to improve the sealing, as shown in fig. 1, in combination with fig. 4 and 6, an extension 4 is further included.

Wherein the extension part 4 is arranged at the edge of the wing part 3 far away from the annular belt 1 along the extending direction of the annular belt 1; when the wing parts 3 overlapped on the two sides of the hump part 101 clamp the hump part 101, the extension parts 4 are abutted on the outer wall surface of the hump pipe 10, so that the extension parts 4 on the two sides are abutted on the outer wall of the hump pipe 10, and a sealing space is formed by enclosing the ring belt 1, thereby playing a role in enhancing the sealing performance. A seal ring may be provided between the extension 4 and the hump tube 10.

Example III

In order to improve the strength of the clip according to the second embodiment, as shown in fig. 1, in combination with fig. 5, a reinforcing rib 5 is further included.

Wherein the reinforcing ribs 5 are arranged between adjacent wing parts 3. The reinforcing ribs 5 are fixedly connected to both end portions of the adjacent wing portions 3 and the outer extension portions 4 and to edges of the ring belt 1 portion located between the adjacent wing portions 3. Generally, the ring belt 1, the wing parts 3, the extension parts 4 and the reinforcing ribs 5 are integrally formed, so that the production cost of the clamp is low and the production difficulty is low.

Example IV

On the basis of the first embodiment, when the clamp is tightened to clamp the hump pipe 10, the clamp is subjected to the reaction force of outward expansion of the hump pipe 10, and the clamp may be stressed excessively to break. Therefore, in order to strengthen the clip, as shown in fig. 1, in combination with fig. 7 and 8, the ear portion 2 is provided with a through hole 201.

The outer ring surface of the end part of the ring belt 1 is provided with a buckling piece 11, and the buckling piece 11 penetrates through the through hole 201 and is clamped on the outer surface of the ear part 2 far away from the ring belt 1. The clip 11 plays a role of reinforcing the connection tightness of the ear portion 2 and the endless belt 1.

Example five

In the absence of technical conflicts, any combination of embodiments one to four is also included.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
