The present invention relates to an apparatus for facilitating fastening of a plug (20) of a branch tee (1), comprising: a body portion (110); A rotation unit 120; A housing part 130; And a holder portion 140. [

The body 110 forms the main body of the present invention and is formed to penetrate up and down. As shown in FIG. 2, the outer shape is preferably cylindrical, but unlike the inner shape, the outer shape is not limited to a cylindrical shape.

The body 110 is vertically penetrated to receive the upper and lower ends of the rotation unit 120 to be described later.

The body 110 accommodates the rotation part 120 so that the rotation part 120 can rotate the shaft.

The rotation part 120 is accommodated in the through hole of the body part 110, is rotated, and the shaft thereof is fixed. However, the rotation part 120 moves upward and downward along the through hole of the body part 110 according to the rotation.

The housing part 130 is coupled to the lower side of the body part 110 and is fastened to the flange 10 of the branch tee 1 to fix the entirety of the present invention to the branch tee 1, There is formed an inner space for temporarily accommodating the high-pressure gas therein.

The housing part 130 has an opening formed at the center of its upper surface like the body part 110 so that the rotation part 120 passes through the opening and fixes the shaft of the rotation part 120, The rotation part 120 is moved up and down through the opening of the upper surface of the housing part 130 according to the rotation.

The holder portion 140 is located at the lower end portion of the rotation portion 120 to hold the plug 20. The holder 140 rotates in the same manner as the rotation of the rotary part 120 so that the plug 20 is rotated and fastened to the branch tee 1.

The individual subcomponents of the components of the present invention as described above are described below.

First, the rotation part 120 includes a shaft part 122; And a shaft handle 121.

The shaft portion 122 forms a vertical main frame of the rotary portion 120 and fastens the plug 20 held at the lower end portion to the opening of the branch tee 1 in accordance with the rotation.

The shaft portion 122 is threaded on the outer circumferential surface thereof and is bolted to an inner circumferential surface of the body portion 110, more specifically to a nut formed on the inner circumferential surface of the feed tube 112, and is vertically transferred according to the rotation.

The shaft handle 121 is located at the upper end of the shaft portion 121 and serves as a handle that allows an operator to rotate the shaft handle 121 to rotate the shaft portion 121.

The operator can tighten the plug 20 while rotating the conventional shaft handle 121. In the past, the operator relied on the feeling of tightening the plug 20 while adjusting the height of the shaft up and down.

The body portion 110 may include a tube 111 forming its outer frame and a feed tube 112 as described above.

2 and 3, the tube 111 may be formed of a rigid metal or reinforced plastic forming the outer shape thereof.

Inside the tube 111, a feed tube 112 is accommodated. The feed tube 112 receives the rotation part 120.

More specifically, the feed tube 112 receives the shaft portion 122 of the rotation portion 120, and is formed as a nut on the inner circumferential surface of the feed tube 112, and a thread is formed on the outer circumferential surface of the shaft portion 122, When the shaft portion 122 rotates, the shaft portion 122 becomes a kind of bolt. The feed tube 112 becomes a kind of nut, and the shaft portion 122 rotates in the feed tube 112, .

For example, when the shaft portion 122 is a right-hand screw, when the shaft handle 121 is rotated clockwise, the shaft portion 122 moves downward, and the shaft handle 121 is rotated counterclockwise When rotated, the shaft portion 122 moves upward.

The body portion 110 may further include a locking pin 113 (see FIG. 2).

The locking pin 113 is positioned to penetrate through the outer frame of the tube 111 and the terminating end thereof presses the outer circumferential surface of the rotating portion 120 and more specifically the shaft portion 122 to rotate the rotating portion 120, Rotation of the shaft portion 122 and its vertical movement are prevented.

The locking pin 113 is formed as a kind of bolt and has an opening like a nut formed in the outer frame of the tube 111 so that the end of the locking pin 113 is pressed against the outer frame of the tube 111 Thereby preventing the rotation of the rotation unit 120 and preventing the rotation of the rotation unit 120.

The body portion 110 may further include a tube handle 114. The tube handle 114 is configured as a kind of handle that provides the convenience of the operator to align the body portion 110 with the housing portion 130 as described above on the plunge 10 of the branch tee 1 .

The operator grasps the tube handle 114 and transfers the weighted invention to the desired location. The tube handle 114 is fixedly attached to the body 110 so that the operator grasps and transports the tube handle 114 rather than holding the shaft handle 121 as described above to transport the present invention.

The operator may grasp the tube handle 114 and the shaft handle 121 respectively in both hands and twist in opposite directions to rotate the shaft handle 121. [

The housing part 130 includes a housing shell 131; And a housing cavity (132).

3, the housing shell 131 forms an outer frame of the housing part 130. As shown in Fig. A housing cavity 132 capable of accommodating a gas as an internal space is formed in the interior thereof.

It is preferable that the housing shell 131 is made of a pressure resistant material enough to withstand the pressure generated by the high-pressure gas.

As described above, the housing shell 131 has an opening for receiving the rotation part 120 passing through the housing part 130. In order to accommodate the above-described gas, It is necessary to seal the gap between the opening of the rotating part 120 and the rotation part 120. [ The housing part 130 may further include a packing part 133 for this purpose.

The packing portion 133 is configured to perform the same function as a gasket of a kind, and prevents leakage of high-pressure gas temporarily accommodated in the housing cavity 132.

The housing part 130 may further include a valve 135 (see FIG. 2) which is located on the outer frame of the outer shell of the housing shell 131 and discharges the gas temporarily accommodated therein.

As shown in FIG. 6, the holder portion 140 may include a quickholder 141 for easily and conveniently holding the plug 20 (see FIG. 5) at its terminating end.

6, a plurality of (two in the figure) grooves are formed in the circumference of the quick holder 141, the grooves are inserted into the nut line 21a of the plug 20, and the quick holders 141 141 are rotated, the circumferential grooves on which grooves are not formed are fastened to each other in such a manner that they are fastened to the nut wires 21a. The quick holder 141 holds the plug 20 in a state in which the quick holder 141 is not turned further in the center groove of the plug 20 when the quick holder 141 is turned only at a predetermined angle.

The holder 140 may further include an elastic part 142 for providing a tension between the end of the rotation part 120 and the quick holder 141. The elastic portion 142 preferably provides a tension between the termination of the rotation portion 120 and the quick holder 141 so that the quick holder 141 can move up and down flexibly And the plug 20 and the quick holder 141 can be made to mesh with each other.

4, the spacing hole 143a is formed on the outer circumferential surface of the end portion of the shaft portion 122, and the holder portion 140 is spaced apart from the end portion of the shaft portion 122 So that the user can have a travel in the vehicle.

As used herein, the singular " include "should be understood to include a plurality of representations unless the context clearly dictates otherwise, and the terms" comprises & , Parts or combinations thereof, and does not preclude the presence or addition of one or more other features, integers, steps, components, components, or combinations thereof.
