Detailed ways

In order to further illustrate the technical means and effects adopted by the present utility model to achieve the purpose of the predetermined utility model, the following in conjunction with the accompanying drawings and preferred embodiments, the following describes a movable joint connection device for an underwater diving suit proposed by the present utility model. The specific embodiments, structures, features and effects thereof are described in detail as follows. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in Figures 1-3, the present invention provides the following technical solutions: a movable joint connection device for an underwater diving suit, comprising an outer joint 1 and an inner joint 2, the inner joint 2 is placed on the inner side of the outer joint 1, and the outer joint 1 The side surface opposite to the inner joint 2 is provided with a first semi-circular arc groove, and after the first semi-circular arc groove is aligned, a first circular circumferential groove is formed, and the interior of the first circular circumferential groove is filled with a connecting piece 4, The inner side of the connector 4 is located on the opposite side surfaces of the outer joint 1 and the inner joint 2 with a second arc groove, and the opposite side walls of the outer joint 1 and the inner joint 2 are fitted and placed through the second arc groove. Seal 3.

In this embodiment, the outer joint 1 and the inner joint 2 are both ring-shaped pieces. In order to satisfy the relative rotation function of the two joints, the connecting piece 4 is made of a flexible circular bar with a certain bending radius and strength, which can easily penetrate the outer joint. inside the circular circumferential groove formed by joint 1 and inner joint 2. And the high-strength performance ensures the reliability of the connection between the outer joint 1 and the inner joint 2, and prevents the two joints from disengaging.

When the outer joint 1 and the inner joint 2 rotate relative to each other, the connecting piece 4 will rotate to a certain extent due to the existence of friction. When the rotation angle is large, both ends of the connecting piece 4 will enter the circular groove. The removal of the connector 4 will have a very large impact, and the removal is very difficult and destructive. Therefore, the use of the connector 4 not only satisfies the relative rotation requirements of the outer joint 1 and the inner joint 2, but also ensures the two The connection reliability of each joint, when the connecting member 4 is about to rotate, the limiting member 6 acts as a restriction, so that the connecting member 4 cannot rotate.

Specifically, the outer side of the first circular circumferential groove is provided with an opening groove 5 on the side surface of the outer joint 1, and a threaded hole is designed at the semicircular groove of the inner joint 2, and a limiter 6 is arranged inside the threaded hole. The use of the limiter 6 in the example avoids the rotation of the connecting piece 4 caused by the relative rotation of the outer joint 1 and the inner joint 2, so that the end of the connecting piece 4 enters the circular groove, resulting in the problem that the connecting piece 4 cannot be taken out normally .

Specifically, the limiting member 6 is a bolt member, the connecting member 4 is a C-shaped member, and the two side surfaces of the limiting member 6 are in contact with the cross-sections of both ends of the connecting member 4. In this embodiment, the outer joint 1 and the inner joint 2 are assembled And dismantling, only need to insert or pull out the connector 4, the operation is simple and easy.

Specifically, the sealing member 3 adopts an annular rubber member. In this embodiment, since the diving suit works underwater, the outer joint 1 and the inner joint 2 rotate relative to each other, and it is necessary to ensure the sealing between the two joints. Therefore, the sealing member 3. The O-ring is used to achieve dynamic sealing, which not only meets the relative rotation requirements of the outer joint 1 and the inner joint 2, but also realizes the sealing between the two joints through the dynamic sealing performance of the O-ring; and the O-ring is a conventional sealing workpiece, which is easy to purchase. with replacement.

Specifically, the inner wall of the outer joint 1 extends inward with a limit ring, and the end of the inner joint 2 extends and contracts inward and is fitted inside the limit ring. In this embodiment, the outer joint 1 and the inner joint 2 are fitted and maintained with each other. The joints are tightly connected.

The working principle and use process of the utility model are as follows: the seal 3 is installed in the second arc groove of the inner joint 2; the outer joint 1 and the inner joint 2 are combined to align the two first semi-circular arc grooves , form a first circular circumferential groove; penetrate the connecting piece 4 from the inside of the opening groove 5 until it passes out from the other side; install the limiting piece 6 .

In the utility model, at the joints of the underwater diving suit, the outer joint 1 and the inner joint 2 are used to complete the connection of the two rotating joints, and the connection is made through the connecting piece 4, which not only ensures the connectivity, but also realizes that the two joints can be connected to each other. Perform relative rotation; the ring-shaped seal 3 makes the joint rotate while ensuring the sealing performance, even if the joint rotates underwater, there will be no leakage; a limiter 6 is added inside the joint to prevent two When the joint rotates relatively, the connecting piece 4 rotates along with it, so as to avoid causing the end to enter into the circular groove and take it out in the same way, which is convenient for the equipment to be used.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Those skilled in the art, without departing from the scope of the technical solution of the present invention, can make some changes or modifications to equivalent examples of equivalent changes using the technical content disclosed above, provided that the technical solutions of the present invention are not departed from. content, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solutions of the present invention.
