Description

A fastening instrument of clamp

The present invention relates to a mechanism for fastening a spring clamp, and more particularly, to a clamp fastening mechanism that is easy to work in a narrow space and shortens working time and can be accurately fastened.

In general, when the vehicle is connected between the various hoses and pipes in the engine ROM, the clamp is fastened to prevent leakage of the assembly and new oil.

These clamps are mainly used for the wire type and the spring type, and recently, the spring type which is advantageous in the leakage pressure is mainly used.

1 is a side view showing a fastening tool of a spring-type clamp according to the prior art.

In the conventional case, when connecting the pipe 102 and the hose 104, the hose 104 is inserted into the end of the pipe 102 by a predetermined length, and then the clamp 106 is fastened to the circumferential portion of the connecting portion to seal the pipe. It works. As the clamp fastening tool, a pliers 108 and the like are mainly used. That is, when the pliers 108 are bitten and compressed on both wings 110 and 112 of the spring-type clamp 106, the clamp 106 is opened and inserted into the connection portion of the hose 104 in the opened state. When the pliers 108 are released after being put in, the hose 104 is compressed by the elasticity of the clamp 106 itself to act as a sealing function.

However, the conventional clamp fastening mechanism as described above uses a common pliers to fasten the clamps. In the case of the engine room of a vehicle of a vehicle, there is a very narrow space in the work space so that a hand for holding the pliers can be inserted. Because it is not prepared, the work is very difficult and the working time is also increased.

In addition, due to the work in a narrow space there is a problem that the clamp is not seated in the correct connection position of the pipe and the hose is leaking and new water occurs.

The present invention was created to solve the above problems, the object of the present invention is to make the hose fastening work more conveniently in a narrow space, such as the engine room, thereby significantly reducing the working time and accurate hose The present invention provides a clamp fastening mechanism capable of preventing leakage and leakage at a connection part because the fastening can be performed at a position.

The clamp fastening mechanism according to the present invention for realizing the above object is fixed to the inner side of the main body and the operating lever is fitted to be slidably movable on the open one side of the main body, one side is open One end portion is fixed to one side of the spring-type clamp and the inner side of the fixed rod, the movable rod is inserted into the fixed rod so that one end is connected to the operating lever and the other end is in contact with the other side of the clamp, It is interposed between the operating lever and the inner surface of the body comprises an elastic member for returning to its original position after the operation of the operating lever.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a cross-sectional view of the clamp fastening mechanism according to the present invention, Figure 3 is a cross-sectional view of the line 2A-A.

The clamp fastening mechanism of the present invention is fixed to the inner side of the main body 2, one side of which is open, an actuating lever 4 fitted to be slidably movable on the open one side of the main body 2, and an inner side of the main body 2. End is in contact with one side of the spring-type clamp (6), the inner side of the cylindrical fixed rod (8), the end is inserted into the fixed rod (8) and one end is connected to the operating lever (4) The other end is an elastic member interposed between the moving rod 10 in contact with the other side of the clamp 6 and the inner side of the operating lever 4 and the main body 2 to return to its original position after the operation of the operating lever 4. It consists of 12 pieces.

The main body 2 has a first catching jaw 14 that prevents the operating lever 4 from being separated in the inner circumferential direction of the opening to a size easily wrapped by the hand.

The actuating lever 4 has a handle portion 16 extending in a circular shape so as to easily hold a finger on one side thereof, and has a predetermined length that is slidably moved to the main body 2, and the end of the main body is circumferentially outward of its end. A second catching jaw 18 is formed to engage the first catching jaw 14.

And the central side of the actuating lever (4) has a shape that is penetrated so that the fixing rod (8) can be inserted, the inner side of the actuating lever (4) is formed a plurality of connecting ribs 20 in the circumferential direction It is connected to the moving rod (10).

One end of the fixing rod 8 is fixed to the inner surface of the main body 2, and the other end of the fixing rod 8 is fixed to the first support member 24 seated on one side wing 30 of the clamp 6, and the operating lever ( A plurality of guide grooves 26 are formed at a portion inserted into the inside of 4) so that the connecting ribs 20 pass by a predetermined width to which the operation lever 4 is moved.

The movable rod 10 is inserted into the fixed rod 8 so as to be linearly movable, one end of which is connected by an operating lever 4 and a connecting rib 20, and the other end of which is the other wing of the clamp 6. A second support member 34 seated at 32 is mounted.

The elastic member 12 is mounted between the actuating lever 4 and the inner surface of the main body 2 to impart a predetermined elastic force when the actuating lever 4 is moved inwardly of the main body 2 to actuate the actuating lever 4. It is preferable that the compression force is made of a compression coil spring to return the operating lever (4) to the original position when the movement force of the) is released.

The action of the clamping mechanism according to the present invention thus made will be described below.

The first support member 30 is seated on one wing of the spring-type clamp 6 and the second support member 34 rests on the other wing 32 of the clamp. When the handle 16 of the lever 4 is pulled and pulled, the operation lever 4 overcomes the elastic force of the elastic member 12 and is moved inwardly of the main body 2. At this time, the movable rod 10 connected to the actuating lever 4 is moved in the same direction as the actuating lever 4 and pulls both wings 30 and 32 of the clamp. Then, the spring clamp 6 is maintained in the open state, so when the operating lever 4 is placed in the desired position, ie, in the circumferential direction of the hose 40 fitted in the pipe 38, the elastic member 12 When the operating lever 4 returns to the one watch by the elastic force of the clamping force, the locking force of the first and second supporting members 24 and 34 caught on both wings of the clamp is released, and the hose is driven by the elastic force of the clamp 6 itself. The tightening is completed in the state which is tightened by the 40.

Therefore, the clamp fastening mechanism according to the present invention configured and operated as described above can be clamped by operating the operating lever from the outside after putting the clip seated on the first and second support members at the position to be fastened. Therefore, it is possible to work more conveniently even in a narrow space such as an engine room, and it can greatly reduce the working time, and it is possible to prevent the leakage and leakage due to the poor fastening because the clamp can be fastened precisely at the position to be fastened. There is this.
