(The first block A1 and the second block A2 have a structure coupled in the transverse direction.)

In the second block (A2), an insertion moving part (A22) is formed in the second adhesion part (A21) so that the aforementioned insertion block (B) can move up and down, and an upper part of the insertion moving part (A22) is formed. A curved ball moving part A23 is formed in the lower direction of the other side of the insertion moving part A22 from the side, and the iron ball BB is built in this ball moving part A23 so as to follow the ball moving part A23. It is provided to be movable.

First, the insertion block (B) includes an insertion portion (B1) to be inserted into the insertion groove (A12), a horizontal portion (B2) formed in a horizontal direction below the insertion portion (B1), and the other side of the horizontal portion (B2). It consists of a vertical portion (B3) bent in the upward direction, so that it can be maintained horizontally without shaking when ascending and descending.

The present invention is characterized in that the first block (A1) and the second block (A2) are coupled and separated from each other by elevating the insertion block (B). For this purpose, an iron ball (BB), a wire ( W) and characterized in that it further comprises a configuration of the push unit (P), with reference to Figures 4 and 5 will be described in more detail with respect to each configuration.

First, the iron ball (BB) is made to move along the ball moving part (A23), and the ball moving part (A23) and the insertion block (B), more precisely, the vertical part of the insertion block (B). (B3) is connected through a wire (W) without elastic force.

At this time, one end of the ball moving part A23 is made to communicate with the outside of the second block A2, and at this time, a departure prevention step A231 is further provided to prevent the iron ball BB from being separated. .

The second block (A2) is formed with a pulley rod (D) on which the wire (W) is spanned. The pulley rod (D) is a lower portion of the curved portion of the ball moving part (A23) and the insertion moving part ( It is formed in the upper direction of A22), and when the iron ball BB is located at one end (refer to FIG. 4) of the ball moving part A23, the insertion block B in the insertion moving part A22 is in a descending state. When the iron ball BB is positioned at the other end (refer to FIG. 5) of the ball moving part A23, the wire W is pulled and the insertion block B rises like a pulley to raise the insertion part B1. is made to be inserted into the insertion groove (A12) of the first block (A1).

That is, the present invention is made to raise or lower the insertion block (B) through the movement of the iron ball (BB), and further includes the configuration of the push unit (P) for this operation, and the push unit (P) includes a first push bar (P1) provided in the first block (A1) and a second push bar (P2) provided in the second block (A2).

First, a push hole A13 into which the first push bar P1 is interpolated is formed in the first block A1. As shown in FIGS. 4 and 5, the push hole A13 is a moving hole ( A132) and a locking hole A131 bent to one side from the moving hole A132, the first push bar P1 includes a push part P11 interpolated into the moving hole A132, and the It is bent upward from the push part (P11) and consists of a handle part (P12) partially exposed in the upper direction of the first block (A1).

In addition, a first elastic body P3 is provided in the push hole A13 to impart an elastic force to one side of the push bar, and the other end of the moving hole A132 is opened to the other side of the first block A1. .

The first push bar (P1) normally has the handle portion (P12) positioned in the locking groove to maintain the first elastic body (P3) in a compressed state, and rotates the first push bar (P1). When the handle portion P12 is placed in the moving hole A132 and then released, the other end of the push portion P11 is momentarily moved to the other side of the first block A1 by the elastic force of the first elastic body P3. It is constructed so that it can protrude.

That is, when the first block A1 and the second block A2 are in close contact, the other side of the moving hole A132 communicates with one end of the ball moving part A23, and the first push bar ( When P1) is operated, the other end of the first push bar P1 instantaneously pushes the side of the iron ball BB located at one end of the ball moving part A23 to move the iron ball BB to the ball moving part A23. By moving from one end to the other end, the insertion block (B) is raised so that it can be fitted into the insertion groove (A12).

This means that the first block (A1) and the second block (A2) are maintained in the coupled state.

Conversely, a second push bar P2 is provided in the second block A2, and one side of the second push bar P2 protrudes to the outer surface of the second block A2 and the ball moving part A23. It is located at the other end, and the second elastic body P4 is provided in the lower part. (The second elastic body P4 is provided in the ball moving part A23.)

As a result, in a state in which the first block A1 and the second block A2 are coupled, the iron ball BB is positioned above the second push bar P2, and at this time, the user When (P2) is lowered and the second elastic body (P4) is compressed and released, the second push bar (P2) rises and strikes the lower portion of the iron ball (BB) to move the iron ball (BB) to the ball moving part ( A23) Move it to one end so that the insertion block (B) descends again.

This means that the first block A1 and the second block A2 are maintained in a separable state.

Therefore, in the present invention, in combining and separating the first block (A1) and the second block (A2), by operating the first push bar (P1) and the second push bar (P2), the first block (A1) easily and the second block (A2) can be firmly fixed or separated to ensure both ease of use, bonding stability, and ease of separation.

Furthermore, the iron ball BB must be accurately positioned at one end and the other end of the ball moving part A23, and for this purpose, a first stopper S1 is provided on one side of the ball moving part A23 to prevent the iron ball BB Prevents arbitrarily moving to the other end of the ball moving part (A23), and similarly, by providing a second stopper (S2) at the other end of the ball moving part (A23), the iron ball (BB) arbitrarily moves to one end of the ball moving part (A23) prevent it from moving

In addition, the iron ball (BB) must pass through the first stopper (S1) and the second stopper (S2) (together referred to as the stopper (S)) through the blow of the push unit (P), for this, the stopper ( S) is made of a soft material to allow penetration of the iron ball (BB) while being compressed.

Furthermore, it is also possible to further provide a magnet (M) on one end of the ball moving part (A23) to position the iron ball (BB) at one end of the ball moving part (A23) through magnetism, and the magnet (M) Silver may be further provided at the other end of the ball moving part A23, and the magnetism is only sufficient to weakly restrict the movement of the iron ball BB, thereby interfering with the movement of the iron ball BB by the blow of the push unit P. It is preferable not to do so.

In addition, in the above description of the present invention, with reference to the accompanying drawings, a packing assembly having improved watertightness having a specific shape, structure and configuration has been mainly described, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and such modifications , changes and substitutions should be construed as falling within the protection scope of the present invention.
