It is spaced downward from 100 to form a spaced space into which the wing portion 310 is inserted, and may be formed extending toward the center of rotation.

Through this, the wing portion 310 is moved upward to a portion where the notch portion 320 is not formed, and then rotated and inserted into the spaced space of the notch portion 320 to be easily coupled.

A protrusion 311 that protrudes outward from the surface of the wing portion 310 and contacts the notch portion 320 or the bracket 100 may be formed.

As shown in FIGS. 1 and 2 , the wing portion 310 has a protrusion 311 protruding from the surface, and the protrusion 311 rotates the wing portion 310 into a spaced apart space of the notch portion 320. When inserted, it contacts the bracket 100 or the notch part 320 and generates friction so that the wing part 310 can be fixed inside the spaced apart space of the notch part 320.

1 and 2, the protrusion 311 is shown to protrude upward, but may be formed to protrude downward, the protrusion 311 protruding upward is in contact with the bracket 100, and the protrusion 311 protrudes downward ) may be in contact with the notch portion 320 .

Through this, after the wing part 310 is inserted into the spaced apart space of the notch part 320, the protrusion 311 is prevented from being rotated by being in contact with the bracket 100 or the notch part 320, thereby preventing the wing part 310 from being rotated. There is an effect of preventing binding termination.

A plurality of protrusions 311 may be spaced apart from each other in a direction in which the wing portion 310 rotates.

As shown in FIGS. 1 and 2 , the protrusion 311 extends in the direction in which the wing 310 rotates, and a plurality of protrusions 311 may be spaced apart from each other.

Through this, it is possible to improve frictional force with the bracket 100 or the notch part 320, and there is an effect of preventing the wing part 310 from being disconnected.

The fastening part 300 includes a protruding part 321 protruding from the inside of the separation space and a recessed part 312 formed to be recessed at a position corresponding to the protruding part 321 in the wing part 310, and the wing part 310 When is rotated and coupled to the notch portion 320, the protruding portion 321 may be inserted into the indented portion 312.

As shown in FIGS. 1 to 4, a recess 312 recessed from the outside may be formed at the center of the wing unit 310, and the notch 320 has a recess 312 at the center of the spaced space. ) A protruding portion 321 may be formed to correspond to.

Through this, when the wing 310 is rotated and inserted into the spaced apart space of the notch 320, the area of the wing 310 rotates to a position corresponding to the entire area of the notch 320, and the recess 312 As the protrusion 321 is inserted, the wings 310 can be fixed in place in the spaced apart space of the notch 320 .

An uneven portion 313 bent in the vertical direction may be formed on the wing portion 310 .

As shown in FIGS. 3 and 4 , the wing portion 310 may be formed to be folded in the vertical direction to form a curved concave-convex portion 313 .

Through this, as the concave-convex portion 313 protrudes upward and downward, when inserted into the spaced apart space of the notch portion 320, the bent concave-convex portion 313 spreads and generates an elastic force, thereby moving the wing portion 310 to the notch portion 320. ) has the effect of fixing it inside the spaced space,

The upwardly protruding portion of the uneven portion 313 is in contact with the bracket 100, and the downwardly protruding portion is in contact with the notch portion 320 to generate friction, thereby generating elasticity and frictional force on the wing portion 310. It has the effect of fixing it in the middle.

The notch portion 320 may include a support portion 322 protruding upward from both ends in the direction in which the wing portion 310 is rotated and supporting the wing portion 310 when combined with the wing portion 310 .

As shown in FIGS. 2 and 4 , a pair of protruding support portions 322 may be provided at both ends of the notch portion 320 in the direction in which the wing portion 310 rotates.

Through this, after the wing part 310 is completely rotated and inserted into the spaced space of the notch part 320, the protrusion part 321 is inserted into the indentation part 312 and at the same time the support part 322 is inserted into the wing part 310. By supporting both ends in the rotational direction, the wings 310 are restrained in a double manner, thereby preventing the wings 310 from being separated from the notch 320 .

A coupling portion 400 formed to correspond to the wing portion 310 or the valve module 200 to couple the wing portion 310 and the valve module 200; may be further included.

As shown in FIGS. 3 and 4 , the wing part 310 may be manufactured as a separate material, and the wing part 310 is provided with a coupling part 400 coupled to the upper part of the valve module 100, and the wing part 310 ) may be detachable from the valve module 200.

Through this, even if a problem occurs because a part of the wing part 310 is damaged and is not completely combined with the bracket 100, after removing the wing part 310 from the valve module 200, a new wing part 310 is installed in the valve module. After coupling to (200), there is an effect of improving the convenience of maintenance by combining with the bracket (100) again.

An embodiment of the coupling part 400 is as follows.

The coupling part 400 includes a hooking part 410 extending in a direction crossing the direction extending from the wing part 310 and an insertion part 420 formed to insert the hooking part 410 in the valve module 200. can

As shown in FIG. 3, the wing portion 310 has a hooking portion 410 extending toward the valve module 200, and is formed on the valve module 200 at a position corresponding to the hooking portion 410 to form the hooking portion. An insertion portion 420 in which 410 is inserted and hung may be formed.

The hooking part 410 and the inserting part 420 are formed as a pair in a direction facing each other so that the wing part 310 can be rotated together when the valve module 200 is rotated.

The coupling part 400 has an insertion hole 430 passing through the center of the wing part 310 and a fixing part 440 that protrudes upward from the center of the valve module 200 and is inserted into the insertion hole 430 and fixed. can be included

A penetrating insertion hole 430 is formed in the central portion of the wing portion 310 and a protruding fixing portion 440 may be formed above the valve module 200, and the fixing portion 440 is the hooking portion 410 It may be inserted into the through hole together with being inserted into the insertion unit 420 .

Accordingly, as the fixing part 440 is inserted into the through hole and fixed, the hooking part 410 is inserted into the insertion part 420 and fixed, in addition to fixing the wing part 310 and the valve module 200 in a double manner.
