Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to better understand the present application, a further detailed description of the present application will be provided below with reference to fig. 1 to 4, and detailed description of the embodiments.

A hose clamp comprises a clamping hoop 10, a protruding part 111 and a positioning part 20, wherein the clamping hoop 10 is in a ring shape and is used for clamping a hose; the protruding piece 111 is arranged on the circumferential side wall of the clamping hoop 10; the positioning member 20 is welded to the boss 111 for fixing the hose.

Hose clamps are used primarily to secure the end of a hose to a nipple, and hose clamps that are attached to the hose prior to fitting the hose to the nipple are tightened to the hose by operating the tightening device 13.

Specifically, referring to the orientation of fig. 1, the clamp ring 10 includes a band 11 and a tightening device 13, wherein the band 11 is bent into a loop shape, and both ends are connected by the tightening device 13 such that the threaded end of the band 11 is located above the other end. The tightening device 13 includes a housing 132 and a bolt 131, the bolt 131 being located between the housing 132 and the collar 10 such that the bolt 131 is in threaded engagement. When the bolt 131 is tightened, both end portions of the band 11 will relatively move in the circumferential direction of the band 10, so that the inner diameter of the band 10 is reduced; when the bolt 131 is loosened, the both end portions of the band 11 also move relatively in the circumferential direction of the band 10, so that the inner diameter of the band 10 increases.

The positioning piece 20 is arranged opposite to the elastic device 13, is welded with the protruding piece 111, and can be embedded into the rubber shell of the automobile hose to realize the positioning function after the elastic device 13 is locked when the automobile hose stretches into the ring-shaped structure enclosed by the strap 11.

Wherein the protrusion 111 is a protrusion extending in the outer wall thickness direction of the clamp ring 10, and the clamp ring 10 is spaced apart from the bottom surface of the protrusion 111. The manner in which the welding process of the positioning member 20 and the protruding member 111 is performed at the welding position includes any welding manner such as arc welding, resistance welding, laser welding, etc. Therefore, the welding part and the clamp steel belt directly have an indirect separation state, and even if corrosion and rust occur at the welding part, the welding part can not spread to the whole clamp steel belt, so that the whole clamp state is not influenced.

In the embodiment of the present application, the protrusion 111 has a disk shape.

Referring to fig. 4, the protruding member 111 is disc-shaped, so that the protruding member 111 and the positioning member 20 are in closer contact, and stress concentration at the welding position of the protruding member 111 and the positioning member 20 is prevented, so that the positioning member 20 is more stable and firm, and positioning is more accurate. Of course, depending on the actual needs, the protruding member 111 may be provided in an oval shape or any other possible polygonal shape, and the welding with the positioning member 20 may be achieved as well, which is not further developed herein.

In the embodiment of the present application, the positioning member 20 includes a connection block 21 and a positioning hook 22. The connection block 21 is welded to the bottom end of the protrusion 111; the positioning hook 22 is vertically connected to the connection block 21 and is disposed toward the clip for positioning the hose.

In the embodiment of the present application, the positioning hook 22 includes a stopper 221, a hook block 222, and a claw 223. The stopper 221 is vertically connected to the connection block 21 for resisting the hose; the hook block 222 is connected with the stop block 221 and forms an obtuse angle with the stop block 221; the two claws 223 are arranged on the hook block 222 at intervals, and the claws 223 form a certain angle with the hook block 222 and are used for fixing the hose. Of course, other types of positioning members 20 may be used.

Specifically, referring to fig. 1, the entire positioning member 20 has a U shape, and the connection block 21 welds the protruding member 111 and extends to the outside of the yoke ring 10 in the axial direction of the yoke ring 10. The connection block 21 is located at one end outside the clamp 10 at a vertical stop 221. When the automobile hose extends into the clamp hoop 10, the stop block 221 is abutted against the end face of the hose for axially positioning the hose, and the two clamping jaws 223 can be quickly and smoothly inserted into the rubber shell of the automobile hose.

The hook block 222 further increases the contact surface of the positioning member 20 with the inside of the hose rubber housing, thereby increasing the snap-fit effect.

The catch 223 prevents the hose clamp from rotating relative to the hose in its axial direction, so that the hose clamp remains in place at all times when the hose clamp is secured to the hose.

In the embodiment of the present application, there is an arcuate transition between the two jaws 223. The arcuate transition may increase the clamping strength of the pawl 223.

In the embodiment of the present application, the protruding piece 111 is press-molded.

Referring to fig. 3, a disc-shaped protrusion is punched at the welding position of the strap 11 and the connection block 21 by using a special riveting die, and the protrusion comprises any possible shape, such as a circle, an ellipse, a polygon, etc., and then the connection block 21 is welded with the protrusion.

In an embodiment of the present application, at least one of the positioning members 20.

The positioning members 20 are sequentially arranged on the circumferential side wall of the band 11, and the size and shape of the positioning members are the same, so that the positioning of the hose clamp can be more accurate by arranging the positioning members 20.

Further, referring to fig. 1, on the inner face of the clamp ring 10, there is provided an elastic means 12 which still tightens the hose clamp in the event that the tightening force of the clamp ring 10 is reduced due to a change in diameter of the clamp ring 10 caused by heat.

It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

Specific examples are set forth herein to illustrate the principles and embodiments of the present application, and the description of the examples above is only intended to assist in understanding the methods of the present application and their core ideas. It should be noted that it would be obvious to those skilled in the art that various improvements and modifications can be made to the present application without departing from the principles of the present application, and such improvements and modifications fall within the scope of the claims of the present application.
