Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile fittings, and particularly relates to a clamp joint for connecting with a hose. Background Technique
[0002] A clamp joint is needed for the connection between the air inlet of an automobile and a hose. A clamp is a kind of pipeline fitting, and its main performance is quick connection and convenient installation, which brings convenience to the connection. The clamp connection method has unique flexible characteristics, enabling the pipeline to have the ability to resist vibration, shrinkage and expansion. Compared with welding and flange connection, the stability of the pipeline system is increased, it is more suitable for temperature changes, thus protecting the pipeline valve parts and reducing the damage of pipeline stress to structural parts, and is applicable to pipeline connections with low pressure.
[0003] Chinese Patent, application number 2024200137342, titled a clamp joint for connecting an automobile air inlet and a hose. The cross-section of the front end of the anti-slip convex joint is a trapezoidal structure, and the width of the rear end of the trapezoidal structure is greater than the diameter of the anti-slip convex joint. At this time, after the hose is sleeved on the anti-slip convex joint, the hose is not easy to fall off. And since there are multiple annular protrusions evenly spaced on the outer wall of the anti-slip convex joint, this further makes the hose not easy to slide on the anti-slip convex joint, avoiding the process of pressing the hose into the annular groove by stamping equipment in the traditional clamp joint, not only saving the process but also facilitating disassembly for hose replacement; one side of the sealing ring is a circular groove, and the inner wall of the circular groove is provided with protrusions, and the other side is a groove, and the groove is arranged near the clamp end. In this way, when the sealing ring expands and contracts due to factors such as temperature, the airtightness will not be affected by deformation; the cross-section of the front end of the stepped joint is a trapezoidal structure, which is convenient for the insertion of the clamp end.
[0004] The clamp of the above patent is straight-line type. During assembly, the length of the first card slot is increased, and the parts are prone to deformation, reducing the tensile strength of the parts. The straight-line type clamp is not conducive to deeper cutting into the bottom of the assembled part groove, reducing the fitting firmness during assembly, and the elastic strength of the straight-line type clamp is relatively low; and the clamp of the above patent has no positioning slot, lacking positioning when the clamp is opened, which is not convenient for the detachment and removal of components; therefore, the utility model proposes a clamp joint for connecting with a hose to solve the above problems. Content of the Utility Model
[0005] The utility model provides a clamp joint for connecting with a hose, aiming to solve the problems raised in the background technique.
[0006] The utility model is realized as follows. A clamp joint for connecting with a hose includes an anti-slip convex joint and a clamp end;
[0007] The cross-section of the front end of the anti-slip convex joint is a trapezoidal structure.

A plurality of annular protrusions are evenly spaced on the outer wall of the anti-slip convex joint, and a hose is sleeved on the outer wall of the anti-slip convex joint;
[0008] A snap ring assembly groove, a snap ring positioning groove and a limiting ring are provided on the snap ring end. A snap ring is sleeved on the outer wall of the snap ring end, and the snap ring is clamped with the snap ring assembly groove. The snap ring includes a snap ring lug and a snap ring assembly section. When the snap ring is opened, the snap ring lug realizes the positioning of the snap ring through the snap ring positioning groove. The snap ring assembly section is an arc-shaped structure, and the limiting ring is used to limit the snap ring.
[0009] Preferably, a plurality of snap ring assembly grooves are provided, and the plurality of snap ring assembly grooves are distributed in a circular ring on the snap ring end.
[0010] Preferably, two oppositely distributed snap ring lugs are provided on two end faces of the snap ring. The snap ring lugs are axially bent and then extend for a section after being bent 90°.
[0011] Preferably, an inner groove is provided on the inner wall of the snap ring end, and a sealing ring is provided in the inner space of the inner groove.
[0012] Preferably, the snap ring is clamped with the snap ring assembly groove through at least three positioning points.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] The function of the snap ring assembly groove is: when the snap ring is opened, the positioning of the snap ring is realized. At this time, the snap ring will not rebound, which is convenient for the detachment and removal of parts during the assembly of parts; the function of the snap ring positioning groove is: it is used for the connection and fixation between this joint and the fitting together with the snap ring; the limiting ring forms a limit on the snap ring, making it not easy to fall off; two oppositely distributed snap ring lugs are provided on two end faces of the snap ring. A certain width is left between the two snap ring lugs during the design, which is convenient for the operator to better dial the snap ring lug. At the same time, this snap ring is changed from the radial bending in the comparative document to axial bending, and after being bent 90°, it extends for a section, which just can cooperate with the snap ring positioning groove to realize the positioning of the snap ring; at least three snap ring assembly sections are provided on this snap ring, and the snap ring assembly section is arc-shaped. On the one hand, it can reduce the length of the snap ring assembly groove 21 in this part, making the part not easy to deform and improving the tensile strength of the part. On the other hand, it can effectively cut deeper into the bottom of the groove of the assembled part, increasing the fitting firmness of the assembly. Thirdly, due to the arc design, through the plastic deformation of the metal, the elastic force of the snap ring is increased compared with that of the straight shape. Fourthly, since the length of the snap ring assembly groove is reduced, the cutting time of machining is reduced at the same time, improving the production efficiency.
