Definitions
- the present invention relates to a hose fastening clamp that is fastened to joints of various connection pipes and used to fix a contact pipe and maintain airtightness, and prevents the shell of the hose contacting the band from being pushed along the direction of rotation of the band. And it relates to a hose fastening clamp that can increase the binding force by the fastened band.
- HOSES which are used in various fields, are manufactured and used in various materials and forms according to materials, heat treatment methods, uses, and installation locations, and are frequently used because of their low price and easy installation.
- the hose is bent or bent depending on where it is installed and is configured to abut the adjacent hose, the connection portion of the adjacent hose is fastened to prevent the transfer of the conveyed material from the hose to the outside and to increase the coupling force of the adjacent hose
- the clamp is coupled to the connection.
- Conventional fastening clamps have a clamp band portion formed with a thread at a predetermined interval on one surface, and a coupling screw portion for adjusting the length of the clamp band portion by rotation, and the length of the clamp band portion is adjusted by the rotating screw portion to rotate the connection portion of the hose. It is made in the form of pressing.
- the clamp band portion 110 made of a plate shape and the thread 111 is formed at a predetermined interval on one surface and the screw thread formed on the clamp band portion 110 ( 111 and a fastening screw part 120 for screwing together, the fastening screw part 120 is provided with a screw head 122 for rotating it.
- the fastening screw unit 120 rotates to advance or reverse the screw thread 111, whereby the clamp band unit 110 presses the hose S.
- This conventional fastening clamp does not have a problem when the conveyed material introduced into the hose at a relatively low speed and low pressure, but when the flow rate of the conveyed material is high and the pressure is high, there is a problem that is easily loosened by the expansion of the hose and the adjacent hose As the clamp for pressurizing the connection is released, accidents frequently occur when the conveying material inside the hose leaks to the outside.
- the conventional fastening clamp is fastened while the clamp band part is advanced by the fastening screw part rotating based on the point where the clamp band part is inserted into the fastening screw part, and the distance of the hose on the clamp band part side entering the fastening screw part is far.
- the thickness of the outer cover is significantly different.
- the outer shell thickness of the hose is thin because it is at a distance, and the thickness of the hose at the point "9" is close to the insertion direction at the insertion position "11", so the outer shell of the hose which can be checked at the position of "3" It is formed to a thicker shell.
- Such a conventional fastening clamp cannot bind in a state in which the outer shell thickness of the hose is kept constant, and after a long time after the fastening, the fastening force is gradually decreased by the outer shell of the hose having the property of returning to its original state. There was a problem that occurred, and when bound with excessive force when binding, a problem occurred that the outer shell of the hose is damaged.
- bent portions are formed on both sides of a pair of plate-shaped band bodies to insert a fixing pin having a through hole and a fixing pin having a spiral hole to insert a bolt from the through side and fasten with a counterpart threaded hole.
- the auxiliary gripping tube is installed inside the band body so that the main body surface is clamped while being pressed by the band body adjusted according to the tightening operation of the bolt.
- the auxiliary narrow tube is not only troublesome to install the inner side of the band body, but also has to be installed by a skilled worker to find the correct position when the auxiliary narrow tube clamps the main body of the tube by the pressure transmitted from the band body It is possible to increase the binding force generated, the above operation is not easy and when the main surface of the tube is made of an elastic material, the auxiliary narrow tube is pushed up and pushed to a predetermined position while expanding outward to the upper or lower portion. There was a problem of falling off.
- the present invention is to solve the problems as described above, while pressing the outer shell of the hose to increase the binding force does not damage the outer shell when binding,
- hose fastening clamp it is easy to combine the hose can be easily used by ordinary users as well as skilled workers to provide an improved hose fastening clamp.
- the purpose is to provide a cost-effective hose fastening clamp by reducing the burden on the additional maintenance and repair costs for hose fastening, because the configuration is simple and easy to manufacture.
- the thread is formed on the outer surface, the band forming an open ring surrounding the hose;
- a tightening screw coupled with the screw thread to adjust the diameter of the open ring; It is disposed to be in contact with the inner surface of the band, characterized in that consisting of the holding member which changes in diameter in conjunction with the change in the diameter of the opening ring.
- the gripping member is formed to protrude outward from the predetermined position of the body and the body, characterized in that consisting of a coupling portion for coupling with the band.
- the coupling portion is characterized in that it comprises a first coupling portion consisting of a fixing portion which is bent and fixed to the outside of the insertion hole and the inserted band is inserted into the band.
- the coupling part is characterized in that it comprises a second coupling portion consisting of a slot portion formed with a predetermined length of the slot for receiving the left and right edges of the band.
- the coupling portion is characterized in that formed on one or both ends of the holding member.
- Hose fastening clamp according to the present invention can obtain a high binding force without damaging the outer shell of the hose when tightening the adjacent hose, the binding force is always maintained even after a long time after tightening to maintain watertightness, airtightness, etc.
- the cost can be reduced and there is an advantage of preventing safety accidents because the conveyed material inside the hose is not exposed to the outside.
- the simple configuration has the advantage that can be easily used by skilled workers and general consumers,
