The pipe hanger such as a side hanger or a vertical hanger is composed of two members having a semicircular shape, and the two semicircular members are connected so as to be rotatable on one side and to be connected on the other side. FIG. 1 is a photograph showing a conventional vertical hanger, and FIG. 2 is a side view showing a conventional vertical hanger. As shown in FIGS. 1 and 2, in the past, bolt-nut fastening or a complex locking device has been inevitably implemented for fastening a hanger. In addition to such pipe hanger as well as band clamp, a locking device is formed on one side. Such a locking device has to be realized by bolt-nut fastening or complicated locking device.

However, the bolt-nut fastening causes considerable inconvenience in the case where the fastening and disengagement of the piping material are repeated from time to time. In addition, the conventional locking device requires a process of fastening the bolt and fastening the nut, thereby causing a substantial air increase. In addition, a hanger that has been locked and locked in a piping material has a considerable inconvenience when it is necessary to release the lock and perform a secondary operation on the piping material.

Especially, in the system air conditioner piping construction, the refrigerant pipe for the refrigerant must be assembled with the respective hoses, welded together with the thermal insulation material and the taping process, and the drain hose is covered with the thermal insulation material and the taping process As always, at least two or three locks and releases are repeated. Also, the piping for heating is repeatedly locked and unlocked at least once or twice by the thermal insulation overlay and taping process. Therefore, it is necessary to facilitate the locking and unlocking of the hanger.

In order to solve this problem, a hanger locking device using a fixing pin or a spring has been proposed. 3, 4 and 5 are hanger locking devices using a conventional fixing pin or a spring. As shown in Figs. 3, 4 and 5, the locking device of the hanger using the fixing pin or the spring was an improved form of the locking device of the hanger using the bolt-nut fastening in terms of the fastening repeatability. However, such a conventional locking device has to be constructed with a complicated structure, and it has been required to attach a separate member such as a fixing pin or a spring in addition to the increase in the unit price, so that the defect rate has increased and the worker has complained due to the lowering of the binding force.

Accordingly, the present invention has been made to solve the above-described problems.

It is an object of the present invention to provide a method of automatically locking and unlocking a cross section and a cross section of a plate material molded to a specific geometric male and female shape by elasticity without unintentionally unlocking it without a separate fixing device such as a separate bolt, Which can not freely be unlocked, and a hanger using the lock device.

As shown in FIG. 6, the arm body joint 1 can be divided into an upper space A and a lower space B in relation to the arm body joint. The upper space A is divided into a space capable of inserting and releasing (unlocking) the water fastening portion 2 and used and the lower space B is divided into a space where the water fastening portion 2 is fastened . More specifically, the two insertion holes of the upper space A of the arm body assembly 1 can be used as a space into which the male fastening portions 2 are inserted and separated. In the lower space B of the arm body assembly 1, Can be used as the fastening space of the male fastening portion 2. [0054] That is, the insertion portion of the male coupling portion 2 inserted into the insertion hole of the upper space A of the female coupling portion 1 is automatically inserted into the female coupling portion 1 by the elastic force of the clamp or the body constituted by the male coupling portion 2, Can be seated and fastened to the lower space (B)

The two insertion holes in the upper space A of the arm body assembly 1 are constituted by the first insertion holes 21 and the second insertion holes 30 from the left side and the first fastening holes 10 are formed on the left side of the insertion holes Lt; / RTI >

The first fastening hole 10, the second fastening hole 20, the third fastening hole 24, the second fastening hole 24, and the second insertion hole 30 from the left side in the lower space B of the arm body assembly 1, ≪ / RTI >

The first insertion portion 40 of the male fastening portion 2 is inserted into the first insertion hole 21 of the female body 1 and the upper space A of the second insertion hole 30 of the female body portion 1 is inserted The second inserting portion 50 of the male fastening portion 2 is inserted. The fastening space C of the first inserting portion 40 is fastened to the second fastening hole 20 and the first fastening hole 43 of the fastening portion 2 is fastened to the first fastening hole 10 The second projection 53 is fastened to the third fastening hole 24 and the fastening space C of the second insertion portion 50 is fastened to the lower space B of the second insertion hole 30.

The first fastening pillar 16 can be formed between the first fastening hole 10 and the second fastening hole 20 of the arm body assembly 1 and the second fastening hole 20 of the arm body assembly 1 A projecting portion 22 may be formed between the third fastening holes 24 and between the third fastening holes 24 and the second fastening holes 30 of the fastening body 1, ) Can be configured.

The first trough 42 of the first insertion section 40 is fastened to the first fastening column 16 and the second trough 52 of the second insertion section 50 is fastened to the second fastening column 26. [ . The first and second fastening columns 16 and 26 of the arm body assembly 1 prevent the fastened water fastening portions 2 from being separated from each other. More specifically, the first and second fastening columns 16 and 26 limit the movement of the fastening portion 2 to the left / right / front and back in the lower space B of the arm body joint 1 due to an unexpected or unintended external force The movement of the clamping portion 2 in the right direction which is the releasing path of the clamping portion 2 even if the clamping portion 2 of the clamp exceeds the elastic amount and is located in the space A above the projecting portion 22 of the clamping portion, To provide a stable fastening force.

A protrusion 22 is formed between the second fastening hole 20 and the third fastening hole 24 of the arm body fitting 1. [ The protruding portion 22 may protrude upward from the lower end of the lower space B within a range that does not invade the upper space A of the arm body unit 1. [ The protrusion 22 prevents the left and right movement of the male coupling portion 2 from being affected by the insertion and removal of the first insertion portion 40 of the male coupling portion 2, 2) can be prevented from being unintentionally released.

The projecting portion 22 formed on the right side of the second fastening hole 20 of the arm body assembly 1 can also act to generate elasticity in the fastening portion 2. When the male coupling part 2 is inserted into the upper space A of the female coupling part 1, the bottom face of the vertex of the first insertion part 40 of the male coupling part 2 is seated on the upper face of the projection 22 . At this time, an elastic force is generated in the male coupling portion 2 by the height of the projecting portion 22 (the step of the insertion locus of the male coupling portion 2). This elastic force can be calculated by the following equation.

In the above equation (1), F is the elastic force generated in the coupling part 2, k is the elastic modulus of the main body or the clamp to which the coupling part 2 is connected, and x is the height of the coupling part (2).

In the case where the male fastening portion 2 constituted by the body or the clamp of the hanger is clamped to the female fastening portion 1 without any external force in relation to the step x of the insertion locus of the male fastening portion 2, In the case of inserting the water tightening portion 2 into the upper space A of the arm body fitting portion 1 after the external force is applied to the water tightening portion 2, The difference in the position of the water fastening portion 2 in contact with the joint 1 becomes the step x of the insertion locus of the water fastening portion 2. [

When the worker pushes the insertion portion of the male fastening portion 2 to the boundary between the fastening space C and the fastening passage D in the female body coupling portion 1, The whole of the male fastening portion 2 is slid in the direction guided by the fastening passage D while being brought into contact with the right side wall of the second insertion hole 30 of the female body 1. The lower end of the first insertion portion 40 is slid from the upper end surface of the protruding portion 22 in the process of sliding the arm body coupling 1 into the coupling passage D of the water coupling portion 2 and sliding to the left side, The elastic force stored in the male fastening portion 2 is released so that the fastening space C of the male fastening portion 2 is naturally seated in the lower space B of the female body fitting portion 1 So that the female / male fastening part can be fastened and fastened.

In addition, with the restoration of the elasticity, when the hanger is connected after the piping material is mounted, the clamp constituted by the water tightening portion is pressed by the load of the piping material or the heat insulating material to the lower portion and the outer portion of the body, So that the fastening space C of the portion is more firmly shaped and the fixing force is naturally strengthened.

The protruding portion 22 may be configured to have a slight inclination (for example, about 12 deg. Rearward) to the rear side of the arm body joint 1. This is to allow the tip end of the first insertion portion 40 of the male coupling portion 2 to slide naturally when the tip of the first insertion portion 40 contacts the projection 22. [

The hanger may be composed of a body connected to the computer bolt and a clamp connected to one end of the body and fastened at the other end of the body. In the above description, it is assumed that the direction of the elastic force is directed downward for convenience of explanation of the locking device. However, according to the embodiment of the present invention, when the female joint part 1 is formed in the clamp of the hanger and the water fastening part 2 is formed in the body of the hanger, the direction of the elastic force of the steel plate material as the hanger material is operated upward.
