Description

Clamp for Hose {HOSE CLAMP}

[0001] The present invention relates to a clamp for a hose, and more particularly to a clamp for a hose such that an end of a screw support does not protrude to the outside of the band by pressing the teeth of the band.

Hose Clamps are used to control the brake or air conditioning system, power steering or the hose used to distribute fluid or gas to the engine room or other hoses connected to the flow of fluid or gas at other industrial sites. And so on.

A variety of clamps for hoses have been used in the past, and a clamp having a correcting function for preventing the clamping force from being lost by correcting the diameter of the hose due to aging due to use for a long period of time And a representative example thereof will be described with reference to FIGS. 5 and 6 as follows.

A hermetic clamp 1 having a correction function to which a conventional technique is applied is provided with a clamp body 2 by bending a plate member having elasticity to a predetermined width in a circular shape, The securing housing 3 is fixed and the fastening bolt 4 is engaged.

The fastening bolt 4 is coupled with a screw 5 formed at the shaft portion of the fastening bolt 4 in the inward direction from the left end of the clamp body 2 and is moved in the forward and reverse directions of the fastening bolt 4 with respect to the right end, The threaded portion 6 is formed so that the diameter of the body 2 can be reduced and enlarged.

The tightening bolt 4 is provided with a torque limiting means 8 for preventing the hose 7 from being excessively interrupted by a predetermined torque or more. The hose 7 is provided in the middle of the clamping body 2 for a long time, (9) capable of interrupting the hose with elasticity so as to be reduced when the diameter of the hose is reduced.

The torque limiting means 8 is provided with a head 10 for tool use at the outer end of the tightening bolt 4 and a break portion 11 having a reduced diameter between the head 10 and the shaft portion And when the force exceeding the set torque is transmitted, it is broken and can no longer be fastened.

The correction means 9 holds an arc-shaped correction body 12 on the inner side of the clamp body 2 and a W-shaped leaf spring 13 is provided between the correction body 12 and the clamp body 2. [ As shown in Fig.

However, in the above-described prior art, since the torque limiting means and the correcting means are provided separately from each other in a separated state, the structure of the hose clamp becomes complicated, and as a result, the manufacturing easiness can not be provided. Which leads to an increase in production cost.

Therefore, the applicant of the present invention applied the clamp for the hose of Korean Patent Registration No. 10-1246876, but the end of the band is protruded outward without being pressed, There was a problem of damaging the surrounding hose.

Korean Registered Patent No. 10-1246876

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a support structure, in which a support protruded outward at a position spaced apart from a head formed at one end of a screw is additionally provided, It is possible to prevent the end of the band from protruding to the outside by pressing the housing by using the support and pressing it again by using the support.

In another embodiment of the present invention, the screw includes a screw head and a screw body at both ends of the screw body. When the power of the tool is transmitted to the screw support, the screw head and the screw body are connected to the hose clamp The hose is interrupted by reducing the diameter of the hose so that the engagement can be completed at the optimum torque so that the application of the excessive torque can be restricted so that the hose can be prevented from being damaged.

A support protruding outward at a position spaced apart from a head formed at one end of the screw is additionally provided so that the band protruded through the housing can be pressed first using the housing and then pressed again using the support So that the end of the band is prevented from protruding to the outside, thereby preventing the end of the band from damaging the surrounding hose in advance.

In addition, the present invention has an effect of preventing the hose to be broken by damaging the coupling portion between the screw head and the screw body when the torque greater than a certain torque is applied to the screw head.

The screw 150 may include a body 152, a screw head 151 formed at one end of the body 150, a screw head 151 spaced apart from the screw head 151 at a predetermined distance, And a gear 154 protruding outward from the other end of the screw support 153 and adapted to be engaged with and fixed to the teeth of the band inside the housing.

The head 151 and the support 153 of the screw are formed in a disk shape and the thickness of the screw head 151 and the support 153 corresponds to the interval between the teeth of the bands, Is pressed and clamped between the tooth and the tooth on the upper surface of one end of the band 110 which has passed through the housing so that the end of the band can be prevented from protruding to the outside. The gear 154 of the screw 150 first presses the tooth 112 of the band 110 and the screw support 153 moves the other end of the band that has passed through the housing 130 to 2 It is possible to prevent the end of the band from protruding outwardly by pressing the car so that the problem of damaging the surrounding hose by the end of the band, which is conventionally generated as shown in FIG. 6, can be prevented.

The diameter of the support 153 is formed to be larger than the diameter of the head 151, so that the support 153 can be directly pressed onto the band bent and bent downward.

The screw 150 has a screw head 151 and a screw body 152 at both ends of the screw body 152. When the power of the tool is transmitted to the screw support 153, By allowing the screw head 151 and the screw body 152 to reduce the diameter of the hose clamp to interlock the hose and complete the tightening at the optimum torque, it is possible to limit the application of excessive torque, .
