4 is an exemplary view showing a pipe support according to the present invention.

The pipe support 100 is formed of a material having a strength and an elastic force (for example, a metal material) and includes a first body 110 and a second body 120.

The first body 110 is formed in a shape of "∩" so that the first pipe 1 is inserted into the interior of the upper end and is in close contact with the inner circumferential surface of the upper end, and a fitting groove 111 is formed at one end of the first body 110 do. The fitting groove 111 is a space that is rotated in a state in which the fitting piece 211 of the coupling lever 00 to be described later is inserted. The fitting groove 111 is a reinforcing piece having a predetermined thickness along corners so as to reinforce the strength, 112 may be formed.

The second body 120 is extended from the one end of the first body along the longitudinal direction by a predetermined length. The second body 120 is provided at one side with a second pipe 2 perpendicular to the first pipe 120, U "-shaped second pipe insertion groove 121 is formed. The second pipe insertion groove 121 may be pressed or pressed by the second pipe 2 during the process of fixing the first pipe and the second pipe while tightly contacting the first pipe and the second pipe, A thick reinforcing bar 122 may be formed.

5 is an exemplary view showing a clamping lever 200 according to the present invention in which the clamping lever 200 is detachably coupled to the pipe support 100 and connected to the first pipe 1 and the second pipe 2 are securely fixed.

It is preferable that the locking lever 200 is formed of a metal having a slight elasticity while being excellent in strength.

The clamping lever 200 includes a turning part 210 which is in close contact with an outer circumferential surface of the first pipe 1 and in which a fitting piece 211 to be inserted into the fitting groove 111 protrudes outward from both side ends, And a lever body 220 formed to extend from the bottom surface of the rotary part to a predetermined length so as to be in close contact with the outer circumferential surface of the second pipe and to support the second pipe.

A semicircular sliding guide groove 212 is formed at the upper center of the rotary part 210 so as to surround the lower outer peripheral surface of the first pipe. When the pipe support 100 and the coupling lever 200 are fastened to each other, the fitting piece 211 is inserted into the fitting groove 111 and then the lever body 220 is pressed toward the second pipe 2, When the fitting piece 211 is fitted into the fitting groove 111, the outer circumferential surface of the upper part of the rotating part is brought into close contact with the first pipe, so that abrasion due to friction may occur during the rotation. Therefore, it is preferable that a semicircular sliding guide groove 212 is formed at the upper center of the rotary part to prevent abrasion of the rotary part and the first pipe which are in close contact with each other when the tightening lever is rotated.

A pair of latching grooves 123 are formed on both sides of the lever body 220 to extend a predetermined length of the latching piece 221 and both sides of the second body 220 are inserted into the latching groove 123 Respectively.

The latching groove 123 is formed on the side surface of the second body and is formed on the movement path of the latching piece 123 so that the latching piece is inserted into the latching groove when the latching lever is pivoted to restrict movement of the latching lever in the reverse direction do.

The clamping lever 200 can secure the first pipe and the second pipe while being fastened to the pipe support through the lever principle without the engagement piece 221 and the engagement groove 123. However, since it can be easily released by an external person and the locking state gradually loosens due to external force (for example, strong wind), the binding force between the first pipe and the second pipe may be lowered. The pipe may be disassembled and the skeleton of the plastic house may be disassembled.

Therefore, when the locking lever 200 is rotated, the locking piece 221 is inserted into the locking groove 123 so that the locking lever can not be moved in the reverse direction. Thus, the locking lever can be separated from the locking lever, Can be prevented from being lowered.

Meanwhile, the latching piece 221 may be formed to be bent outwardly from the edge of the lever body 200 toward the end thereof.

Since the locking lever 200 has a predetermined elastic force, when the locking piece 221 is bent in an outwardly bulging shape from the edge to the end of the lever body 200, when the locking lever 200 is pressed, 221 are pushed in by the inner circumferential surface of the second body 120. When the engaging pieces 221 reach the engaging grooves 123, they are inserted into the engaging grooves while naturally expanding outwardly by the elastic force So that the clamping lever 200 and the pipe support 100 are fastened together.

Since the pipe support 100 has a predetermined elastic force, when the lever body 200 is drawn into the second pipe, the lower portions of the first body 110 and the second body 120 are widened outward by a predetermined distance So that the engaging piece 221 is smoothly inserted into the engaging groove 123.

Therefore, since the first pipe 1 and the second pipe 2 are inserted into the pipe support 100 in a vertically intersecting manner, the operation of fastening the fasteners through the fastening lever 200 can be quickly performed, There is an advantage that the time can be remarkably shortened.

Further, when the engaging piece 221 is inserted into the engaging groove, the engaging piece maintains the shape of being widened due to the elastic force. Therefore, even when the engaging lever 200 is pulled in the opposite direction, It is possible to maintain the state of being bound. Therefore, it is possible to prevent the outsider from loosening the tightening lever 200 and prevent the binding force from being lowered due to external force (for example, strong wind).

In order to prevent the lever body 200 from being bent or short-circuited when the lever body 200 is pressed, the pivoting unit 210 is configured such that when the pivoting lever is pivoted, Sectional shape so as to prevent it from being bent or short-circuited in the inside of the frame.

As described above, the clamping lever is firmly fixed to the second pipe through the lever principle, and the first and second pipes are firmly fixed. The pivoting part 210 is a fulcrum, the lever body 220 gripped by the operator is a point of weakness, When the clamping lever 200 is pressed toward the second pipe 2, a force is exerted on the body of the lever body 220, so that the lever body is simply pressed against the plate 2, If it is formed in one plate shape, it may be bent or bent at the time of rotation.

Since the force acts also on the pivoting portion 210 which is the fulcrum point due to the lever principle, the fitting piece 211 may be bent or short-circuited during the pivoting of the pivoting lever, A problem may arise in that it is bent. Therefore, it is preferable that the turning portion is formed in a "?" Shape in cross section to reinforce the strength. Further, when the tightening lever 200 is pivoted toward the second pipe 2, the bent edge of the pivoting part slides on the outer circumferential surface of the first pipe, thereby preventing abrasion due to friction and allowing the tightening lever to pivot smoothly. It is preferable that the outer peripheral surface of the bent edge be rounded.

Next, in the present invention, a pair of cutouts 113, which are cut out by a predetermined length in the inner diagonal direction from the end portion, are formed symmetrically with respect to the center at the upper end of the first body, An elastic contact portion 114 having a predetermined elastic force is formed.

Here, the elastic contact portion 114 is bent downward at a predetermined angle.
