AI Technical Summary
The existing automotive hose clamp has a single structure and is easy to loosen when tightening. Especially when the height of the convex hull is low, the coordination between the clamp and the shell is very likely to fail.
The shell device with a car hose card hoop is designed. By setting up convex blocks on the cardband, and setting a groove adaptation with the convex block on the housing, the groove and the convex block are tightly fastened, enhanced the tightness, and enhanced it to enhance the tightness and enhance the convex block. The tightening effect of the cardpot belt is prevented from loosening.
Effectively improves the tight effect of the stuck band, and ensures the stability of the stuck when the card hoop is tightened. Even if the height of the convex block is low, the groove can still be buckled with the convex block to prevent the stuck band loose.

[0001] The utility model relates to the technical field of automobile pipe connection, in particular to a shell device of an automobile hose clamp. Background Art
[0002] With the continuous development of automotive fasteners, hose clamps have become the mainstream product of automotive fasteners. However, the structure of hose clamps needs to be continuously optimized to ensure the fastening effect of the clamps. The existing hose clamps have a single structure, mostly consisting of a clamp band, a locking bolt and a shell. There is a risk of loosening when the clamp is tightened.
[0003] The hose clamp housing and the clamp band of the prior art are assembled together, and the rear of the housing is buckled by the convex bump on the clamp band. The strength of the convex bump is crucial for assembly. Once the height of the convex bump is too low, the convex bump and the housing are likely to loosen when the clamp is tightened.
[0004] Therefore, how to solve the deficiencies in the above-mentioned prior art has become a topic to be studied and solved in this application. Utility Model Content
[0005] In view of this, an object of the utility model is to provide a housing device for an automobile hose clamp.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A shell device for an automobile hose clamp comprises a clamp band, a locking bolt for tightening the clamp band once, and a shell for tightening the clamp band twice, wherein the clamp band is in a ring-shaped structure, a through hole is provided on the shell and the two ends of the clamp band pass through the shell from the head end and the tail end of the shell respectively through the through hole; the locking bolt extends into the through hole, the locking bolt meshes with the clamp band, and the locking bolt tightens the two ends of the clamp band once; a groove is provided at the bottom wall of the shell and is arranged along the circumference of the clamp band and the groove wall penetrates to the through hole, the clamp band is provided with a protrusion that matches the shape of the groove, and the protrusion is clamped at the groove to tighten the two ends of the clamp band twice.
[0008] Furthermore, the two ends of the clamp band are overlapped, and the two ends of the clamp band are divided into an upper clamp band end and a lower clamp band end, the upper clamp band end is arranged closely against the locking bolt, and the lower clamp band end is arranged closely against the bottom wall of the shell.
[0009] Furthermore, the protrusion includes a first protrusion and a second protrusion, and the first protrusion and the second protrusion are both arranged on the side of the bottom wall of the shell body close to the end of the lower clamp band; the groove includes a first groove and a second groove, the first protrusion is clamped in the first groove, and the second protrusion is clamped in the second groove.
[0010] Furthermore, the first bump and the second bump are both arc-shaped bumps.
[0011] Furthermore, a fixing block for fixing the locking bolt is provided on the housing.
[0012] Furthermore, a limiting block for supporting the shell is provided on one side of the bottom wall of the shell where the lower clamp band end is close to the shell.
[0013] Compared with the prior art, the utility model provides a protrusion on the clamp band and a groove matching the protrusion on the shell, so that the groove can achieve a matching and tightening effect on the protrusion. When the clamp band is tightened, the groove and the protrusion can also prevent the clamp band from loosening. Even if the height of the protrusion is low, the groove can still play a role of buckling with the protrusion. BRIEF DESCRIPTION OF THE DRAWINGS
