Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint for connecting pipes, shafts, and various other things to each other. Conventionally, there are various types of joints. As shown in Figure 171, a flange b is provided on a pipe etc. a, and this is fixed to a flange b' of a connected pipe etc. a' with a fixing device C such as a bolt or nut. .

However, a drawback of such a joint is that it is necessary that a flange b' is also provided on the pipe a' to be connected, and it is difficult to connect to a joint that does not have a flange b' in advance.

The purpose of this invention is to solve these problems, and its purpose is to provide a joint that can be connected even when the object to be connected is not provided with a flange. Figure 72 shows a case where a sensor holding member is connected to a ball falling gutter of a dick machine shown as an embodiment of the present invention. This joint is characterized in that a plurality of pawl members 3f having retractable pawls 2 are provided, and a T actuating device ff4k is provided on the main body 1 to move the pawl members 3 toward or away from each other.

Reference numeral 6 in the figure is an object to be connected, and as an example, the lower end f& of the safe ball falling gutter 8 or the out ball falling gutter 9 of the pachinko machine 7 shown in Figure 3 is generally shown. In general, the rain gutter 8. The 9th grade has a roughly square cross section, is made of synthetic resin, does not have a flange, and the inner or outer edges vary depending on the manufacturer of the pachinko machine. The person who installed the sensor for counting the balls on the lower end of both shafts 819, which have a difference between each other, is Fuga M, who is in a different business from the manufacturer of the pachinko machine. Therefore, the problem is that it is impossible to attach the sensor holding member to the above-mentioned 8.9, which does not have a flange assembly and has an unspecified multi-shaped structure with inner and outer edges. He had it.

The present invention also solves the above-mentioned problems by way of example.

Then, the claw member 3 - for example, draw the drawing line at 4 and 1 as shown in the figure.
A thread is formed, the thread is screwed onto the screw 10, and the claw member 3 is screwed together.
The other end is connected to a piece and fixed to the main body l. Also, this claw member 3 is always held by the spring portion 11.
]A is biased 110,000 times, and by turning the screw 10, it can be moved in the direction of arrow All or its opposite direction. Note that the tip of the screw 10 is provided in contact with the main body l.

Describing the usage of this embodiment, the actuating device 4 is activated in advance to make the recesses between the claw members 3 shorter than the inner width of the gutter 8, and then the claw members 3 are fully inserted into the shaft 8. The actuating device 4 is used to move the pawl member 3 in an outward direction and pull the main body 1 along with it in the direction of arrow A1.

Then, as shown in Fig. 74, the claw 2 sticks into the inner surface of the gutter 8, thereby fixing the main body l and the gutter 8.

Note that in another embodiment, the 0-direction actuating device 4 is formed so as to be erected by a spear. In the figure, 12 is a plate having a screw hole 13, to which the claw member 3 is fixed. 14
indicates solder.

Further, 15 is a sensor, and as shown in FIG. 1, 1'F4, for example, 16 is a light emitting element, and 17 is a light receiving element.

A ball (not shown) falling through the hole 19 blocks the light emitted by the light emitting element 16, and thereby, the interruption of the light entering the light receiving element 17 is sent as a signal 5 to a counter (not shown) for optical transmission. Next, in the present invention, as shown in Figure 7, the claw 2f may be attached to the object to be connected by moving it inward. Furthermore, the concatenated body may be of any suitable shape.

Note that μm1 in 11σ<claw 2 is generally formed of metal,
The material to be connected is preferably made of synthetic resin or the like, which has less hardness than the claw 2, but even if it is made of metal, it may be made of lead or other material with less hardness. Moreover, for materials with high hardness, it is sufficient to form holes, grooves, etc. in advance at the positions where the claws 2 are expected to enter, without providing a flange.

By doing so, it would be possible to connect to a device that does not have seven flange and has a hardness equal to or greater than the claw 2.

This invention is advantageous in that it can be connected to a device without a pre-formed flange due to the above-mentioned condition u17 < 44fl.

It is also possible to connect the sensor holding member to the ball falling gutter of a pachinko machine.
