Then, the release wire is inserted through the bearing portion, the diameter of the slit of the bearing portion is increased, and the end portion of the release wire is disposed in the bearing portion. Thereafter, the cap portion is fitted into the bearing portion based on the information of the wire receiving member, so that the diameter of the slit of the bearing portion is prevented and the release wire is attached to the bearing portion of the wire receiving member which is the device portion. Then, a wire receiving member is set in a drain outlet by a construction worker, a valve body is attached to a rod portion of a release wire arranged in a bearing portion, and construction is completed.

The connection structure between the release wire and the device unit in the above-described conventional example has the following drainage flow.
When the operation part is pushed while the valve body of the drain outlet of the tank body is lowered, the inner wire of the release wire moves forward in response to the pushing of the operation part. At this time, the biasing spring is compressed. Then, since the release wire is connected to the valve body via the rod portion, the valve body is pushed up and raised as the inner wire advances. In this state, the holding mechanism works to hold the advance amount of the inner wire, and the drainage port of the tank body is opened by holding the lift of the valve body, and the drainage in the tank body is drained from the drainage port to the drain pipe. Then, it is drained into a sewer pipe through a drain trap. Further, when the operation unit is further pushed from this state, the inner wire advances a small amount, the holding of the inner wire of the holding mechanism unit is released, and the compressed urging spring is released as the holding mechanism unit is released. The inner wire is retracted by the urging force of the compression release. If it does so, since a rod part will also descend | fall and a valve body will also descend | fall along with retraction | retreat of an inner wire, a valve body will seat on a drainage port and a drainage port can be closed. In this state, since the drain outlet is closed, water can be stored in the tank body. After that, the opening / closing action of the valve body is repeated by the pushing operation of the operation portion. Moreover, in this conventional example, the release wire can arrange | position a rod part in the center part in a drain outlet by a wire receiving member.

Since the connection structure between the release wire and the device unit of the conventional example described in Patent Document 1 is connected to the outer end and the device unit by screwing, when the outer end and the device unit are screwed together, Rotation stress due to screwing is applied to the flange part of the release wire interposed between them, and the outer wire itself is twisted and twisted by applying a force in the direction in which the upper and lower surfaces of the flange part move relative to each other. End up. When such twisting / twisting stress is applied to the outer tube, the outer tube is deformed or broken. In addition, when deformation occurs in the outer tube, it interferes with the inner wire that can be moved forward and backward, and the outer tube is broken by the friction that occurs when the inner wire moves forward and backward. Therefore, it is better not to apply torsion and torsional stress to the outer tube.
In addition, since the outer end is not fixed to anything during transportation to the release wire before construction, there is a problem that the outer end moves up and down around the release wire and the outer end is damaged.
Moreover, since the connection structure of the release wire and apparatus part of the prior art example which is the above-mentioned patent document 2 has connected the outer tube and the apparatus part with the diameter expansion of the apparatus part and the cap body, it adds to a cap body. Since the load must prevent the expansion of the diameter expansion and the connection of the release wire, fatigue damage of the cap body frequently occurs. It was a very problem because I did not do it. Moreover, since the said prior art must comprise a cap body as another member with respect to an apparatus part or an outer tube, the problem that a cap body was lost at the time of construction had generate | occur | produced. In addition, the construction procedure at the site increased the process of “attaching the cap body” by one, so the labor of the worker increased and the workability was poor.

From the above, the present invention solves the following problems.
1. Prevents the outer tube from being damaged by preventing rotational stress from being transmitted to the outer tube when connecting the outer end and equipment.
2. The outer end and the equipment part can be attached by a simple method, reducing work processes and improving workability.
3. While reducing the number of members, there is no risk of members being lost at the construction site.
4). Prevents the outer end from moving in the axial direction with respect to the outer tube during transportation, and prevents damage to the outer end before construction.

It consists of a claw receiving portion 61 configured on the outer peripheral surface of the main body 43 and a claw portion 62 configured on the inner periphery of the outer end 2. When both are connected, the claw portion 62 is elastically expanded by the slit and the diameter is reduced elastically by the concave groove portion of the claw receiving portion 61. Since the claw portion 62 is reduced in diameter by the claw receiving portion 61, both can be elastically engaged and connected.

The connection structure between the release wire and the device part of this embodiment is constructed as follows.
In advance, the release wire 1 is assembled in the factory as follows.
The outer tube 12 is inserted into the hole for inserting the release wire 1 of the outer end 2, and the flange portion 121 is press-fitted into the outer tube 12. In this embodiment, the flange portion 121 is configured by press-fitting a plastic flange portion 121 into the outer tube 12. For example, the outer tube 12 and the flange portion 121 may be configured integrally or by insert molding. It is also possible to change the design such as making the flange portion 121 made of metal.
Then, the inner wire 11 is inserted into the outer tube 12, and the rod portion 111 is caulked and fixed to the inner wire 11. And the rod part 111 of the edge part of the inner wire 11 by the side of the valve body B is also crimped, and the assembly of the release wire 1 in a factory is completed.
Next, the construction procedure at the construction site will be described.
The operation unit 41 which is the device unit 4 is attached to the tank body S, and a drain pipe H and a drain trap are piped to the drain port K of the tank body S. Thereafter, the release wire 1 is connected to the valve body B side end of the remote-operated drain plug device, which is configured on the valve body B side of the drain port K. After that, as shown in FIG. 1A, the end of the release wire 1 on the operation unit 41 side (that is, the end side to which the outer end 2 is connected) is abutted against the end of the operation unit 41. At this time, the rod portion 111 of the inner wire 11 is inserted into the main body portion 43 of the operation portion 41 so that the rod portion 111 is disposed in the operation portion 41, and the flange portion 121 of the outer tube 12 contacts the end portion of the main body portion 43 of the operation portion 41. We hit to touch. Thereafter, the outer end 2 is slid to the operation unit 41 side which is the device unit 4, and the claw portion 62 of the outer end 2 which is the engaging portion 6 is also engaged with the engaging portion 6 as shown in FIG. It is elastically engaged with a claw receiving portion 61 on the outer periphery of a certain main body portion 43. Then, the flange portion 121 is disposed and fixed so as to be interposed between the outer end 2 and the device portion 4 (main body portion 43). As a result, the flange portion 121 of the release wire 1 is connected to the operation portion 41 (device portion 4), but when connecting, it is attached by elastic engagement instead of attaching by screw screwing as in the prior art. Since the outer tube 12 is connected without applying rotational force, the outer tube 12 is not damaged or broken.
In the present embodiment, the flange portion 121 is interposed between the device portion 4 and the outer end 2, so that the outer tube 12 is rotatably connected to the device portion 4. Therefore, after the outer end 2 and the device section 4 are connected, the outer tube 12 is twisted or twisted so that rotational stress is not transmitted to the outer end 2, and an extra load is applied to the tab 62 of the outer end 2. Since it does not add, the damage of the engaging part 6 can be prevented.
Moreover, also about a construction procedure, the engagement part 6 elastically engages only by abutting the flange part 121 of the release wire 1 with respect to the apparatus part 4, and inserting the outer end 2 in the apparatus part 4, and it can connect by one touch. Therefore, workability improved.

The connection structure between the release wire and the device part in the above embodiment is the following drainage flow.
When the operation shaft 42 is pushed while the valve body B of the drain outlet K of the tank body S is lowered, the inner wire 11 of the release wire 1 moves forward in response to the pushing of the operation shaft 42. At this time, the urging spring 5 (not shown) built in the release wire 1 is compressed. Then, since the release wire 1 is connected to the valve body B side, the valve body B is pushed up and raised as the inner wire 11 advances.

The flange part 121 will be elastically engaged. This is because the flange portion 121 of the outer tube 12 is hooked and locked to the tab portion 62 of the outer end 2, so that the tab portion 62 of the outer end 2 expands due to elasticity and engages the flange portion 121 of the outer tube 12. can do. Therefore, since the outer tube 12 and the outer end 2 are engaged and fixed, the outer end 2 is prevented from being damaged by moving up and down around the release wire 1 during transportation to the release wire 1. Moreover, the work process which moves the outer end 2 to the apparatus part 4 side at the time of site construction reduces. Here, the assembly of the release wire 1 at the factory is completed (that is, the state shown in FIG. 2B).
Next, the construction procedure at the construction site will be described.
The operation unit 41 which is the device unit 4 is attached to the tank body S, and a drain pipe H and a drain trap are piped to the drain port K of the tank body S. Thereafter, the release wire 1 is connected to the valve body B side end of the remote-operated drain plug device, which is configured on the valve body B side of the drain port K. After that, as shown in FIG. 2B, the end of the release wire 1 on the side of the operation unit 41 (that is, the end side to which the outer end 2 is connected) is abutted against the end of the operation unit 41. At this time, the rod portion 111 of the inner wire 11 is inserted into the main body portion 43 of the operation portion 41 so that the rod portion 111 is disposed in the operation portion 41, and the flange portion 121 of the outer tube 12 contacts the end portion of the main body portion 43 of the operation portion 41. We hit to touch. Then, since the outer end 2 is engaged and fixed in advance on the flange portion 121 of the outer tube 12, the flange portion 121 is automatically interposed between the outer end 2 and the device portion 4 (main body portion 43). So that the arrangement is fixed. And the connection part 7 comprised in the outer end 2 like FIG.2 (c) engages with the connection part 7 comprised in the outer periphery of the main-body part 43, and the connection of the release wire 1 and the apparatus part 4 is completed. In this embodiment, since the flange portion 121 is engaged with the outer end 2, the flange portion 121 of the release wire 1 is abutted against the device portion 4 and the outer end 2 is simply inserted into the device portion 4. Is completed and can be connected with one touch. Therefore, workability improved.

The connection structure between the release wire and the device part in the above embodiment is the following drainage flow.
When the operation shaft 42 is pushed while the valve body B of the drain outlet K of the tank body S is lowered, the inner wire 11 of the release wire 1 moves forward in response to the pushing of the operation shaft 42. At this time, the urging spring 5 (not shown) built in the release wire 1 is compressed. Then, since the release wire 1 is connected to the valve body B side, the valve body B is pushed up and raised as the inner wire 11 advances. In this state, the holding mechanism portion 44 in the main body portion 43 works to hold the advance amount of the inner wire 11, and the drainage port K of the tank body S is opened by holding the lift of the valve body B, Drainage in the tank body S is drained from the drain port K to the sewer pipe through the drain pipe H and the drain trap. Further, when the operating shaft 42 is pushed from this state, the inner wire 11 is advanced by a small amount, the holding of the inner wire 11 of the holding mechanism portion 44 in the main body 43 is released, and the inner wire 11 is compressed by the amount advanced. The compression of the biasing spring 5 is released along with the release of the holding mechanism 44, and the inner wire 11 is retracted by the bias of the compression release. As a result, the valve element B also descends due to its own weight as the inner wire 11 moves backward, so that the valve element B can be seated on the drainage port K and the drainage port K can be closed. In this state, since the drainage port K is closed, water can be stored in the tank body S. After that, the opening / closing action of the valve body B is repeated by the pushing operation of the operation unit 41.

In addition to the above-described embodiments, the present invention can be modified as appropriate without departing from the scope of the claims.
For example, although the outer end 2 is configured and arranged at the end of the outer tube 12 in the above embodiment, it may be configured at the end of the device unit 4 as shown in FIG .
