Description

[Detailed Description of the Invention] This invention relates to a pipe stopper in a diving breathing apparatus that can be easily attached and removed at any position on the pipe attached to the diving breathing apparatus.

A pipe stop 1 in a conventional diving breathing apparatus is made of rubber that can be fitted and locked onto the outer circumferential edge of a pipe 2, for example, as shown in FIG. This is done at the upper end of the pipe 2 each time, so it is difficult for the user to avoid feeling troublesome, and the pipe stopper 1 is
When moving from the set position to the top end of the pipe 2 or vice versa, the pipe stop 1 itself cannot move smoothly relative to the pipe 2 due to bending or twisting due to deformation, and the pipe stop 1 itself may not move smoothly relative to the pipe 2 due to bending or twisting due to deformation. There is a risk of cracking or damage, and in some cases, it may become unusable and have to be discarded, which is not desirable for users in terms of the complexity of attaching and detaching it to the pipe 2 and the cost of materials. .

Therefore, in order to correct the above-mentioned drawbacks, this invention has a rectangular connecting part made of an elastic synthetic resin material and a locking piece with an opening-shaped missing part formed integrally with this connecting part. This is intended to provide a pipe stopper for diving breathing equipment equipped with a pipe.It is extremely easy to attach and detach at any position on the pipe, and the structure is extremely simple, and the user does not feel any trouble when handling it. This eliminates the risk of damage or destruction caused by attachment/detachment.

An embodiment of this invention will be described below with reference to FIGS. 2 to 6. In each of the longitudinal ends of the rectangular connecting portion 5 made of an elastic synthetic resin material, a portion is missing. Arc-shaped locking pieces 6.7 of the same size are integrally formed, and the locking pieces 6, 7 are spaced at the same distance as the outer diameter of the pipe 8, and are connected to the connecting portion 5 as shown in FIGS. 3 and 5. As shown in the figure, they are protruded in the same direction (left side in this case), and missing parts a and b for fitting into and removing from the pipe 8 are respectively provided in the locking pieces 67 and 9 as shown in Fig. 6. In addition, the missing parts a and b are opened in opposite directions as shown in FIG. It is convenient for attaching and detaching from the pipe 8.

In the figure, 10 is a mouthpiece, and 11 is a valve body detachably attached to the upper end of the pipe 8.

Since this idea has the above-mentioned configuration, we now have pipe 8.
When attaching to the pipe, as shown by the chain lines in FIG. Grasp it
When the locking pieces 6 and 7 are rotated 90 degrees in one direction, the missing parts a and b of the locking pieces 6 and 7 are smoothly fitted into the pipe 8, and the locking pieces are attached to the pipe 8 in the state shown by the solid line in FIG. Ru.

Also, when detaching from the pipe 8, if it is rotated 90 degrees in the y2 direction, it will be in the position shown by the chain line in Figure 2.
It can be easily removed from the pipe 8 by pulling the handle 9 toward you through the missing parts a) and b in the open state.

However, since the lever can be attached and detached from the pipe 8 extremely easily at any position on the pipe 8, unlike the conventional pipe stopper 1 shown in FIG. It is difficult to escape the feeling of trouble when attaching and detaching the pipe, and since the pipe is transferred along the pipe 2 each time it is attached or detached, there is a high risk of cracking or damage to the pipe stop 1 itself due to bending or twisting due to deformation of the pipe stop 1. Compared to the conventional products, as mentioned above, the pipe stopper of this invention can be attached and detached at any position on the pipe 8 very easily, and does not make the user feel troublesome. Since there is no risk of cracking or damage, it is more suitable in terms of materials than conventional products, and the locking pieces 6 and 7 have the same outer diameter as the pipe 8 at the longitudinal end of the connecting part 5. Since they are spaced apart and project in the same size toward the same side with respect to the connecting portion 5, together with the elasticity of the locking pieces 6 and 7, the device can be attached to the pipe 8 reliably and easily. It has a good external appearance, is easy to manufacture, and since the opening-shaped missing parts a and b are opened in opposite directions, the pipe 8 has good elasticity.
Since it can be easily and effortlessly attached and detached from the device, it is not only extremely convenient for the recipient to handle it, but also because the structure itself is simple, it can be manufactured at low cost and can be widely supplied to general users. It has the practical benefit of
