[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.
[0015] 1. In the present utility model, after the external connecting wire has been connected to the joint body, the connecting plate, the second electric push rod, the compression spring, the limiting member and the rubber gasket can move back and forth through the telescoping of the first electric push rod, so as to reinforce the connection between the joint body and the connecting wire according to actual requirements in the follow-up. After adjustment, the second electric push rod can be telescoped to drive the limiting member and the rubber gasket to move up and down, so that the limiting member can move closer to the connection part. After being close and fitting, it can be reinforced to ensure more stable connection and prevent loosening due to the force generated during rotation during use.

[0022] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0024] Embodiment 1, as Figures 1-4 shown, a rotatable two-channel joint structure with a joint includes an overall structure 1 and an auxiliary structure 2, and the auxiliary structure 2 is located at the front and rear positions on the outer surface of the overall structure 1; the overall structure 1 includes a fixed cylinder 101, circular grooves 110 are formed in the front and rear outer surfaces of the fixed cylinder 101, a round cover 102 is slidably connected to the center of the inner surface of the circular groove 110, joint bodies 108 are fixedly installed on both sides of the front and rear outer surfaces of the round cover 102, first electric push rods 103 are fixedly installed at the top and bottom of the front and rear outer surfaces of the round cover 102, the extending ends of the first electric push rods 103 are fixedly connected to a connecting plate 104, second electric push rods 106 are fixedly installed at the inner top and inner bottom of both sides of the outer surface of the connecting plate 104, the extending ends of the second electric push rods 106 are fixedly connected to a limiting member 109, and a rubber gasket 107 is fixedly connected to the center of the inner surface of the limiting member 109.
[0025] The effect achieved by the entire Embodiment 1 is, as Figure 1 and Figure 2As shown in the figure, after the subsequent external connecting wire is connected to the joint body 108, its connecting plate 104, second electric push rod 106, compression spring 105, limiting member 109 and rubber gasket 107 can move back and forth through the first electric push rod 103, so that subsequent adjustment can be made according to different reinforcement positions. After adjustment, through the mutual cooperation of the second electric push rod 106, compression spring 105, limiting member 109 and rubber gasket 107, the connection between the joint body 108 and the connecting wire can be reinforced to ensure more stable subsequent connection. And the main source of force of the limiting member 109 is the force exerted by the extension of the second electric push rod 106, while the expansion force of the compression spring 105 can play an auxiliary role, thereby improving the reinforcement effect.
[0026] Embodiment 2, as Figures 1-4 shown, the outer surfaces of the rubber gasket 107 and the limiting member 109 are slidably connected to the outer surface of the joint body 108. A compression spring 105 is sleeved on the outer surface of the second electric push rod 106. One end of the compression spring 105 is fixedly connected to the outer surface of the limiting member 109, and the other end of the compression spring 105 is fixedly connected to the outer surface of the connecting plate 104. A ratchet wheel 111 is rotatably connected to the center of the front and rear inner surfaces of the fixed cylinder 101. A connecting rod 112 is fixedly connected to the center of the outer surface of the ratchet wheel 111. The outer surface of the connecting rod 112 is fixedly connected to the inner surface of the round cover 102. A pawl 115 is rotatably connected to one side of the front and rear inner surfaces of the fixed cylinder 101. A connecting rope 116 is fixedly connected to the outer surface of the pawl 115. The outer surface of the pawl 115 is slidably connected to the outer surface of the ratchet wheel 111. A fixing plate 113 is fixedly connected to the front and rear inner surfaces of the fixed cylinder 101. A spring 114 is fixedly connected to the top of the fixing plate 113. One end of the spring 114 is fixedly connected to the outer surface of the fixing plate 113, and the other end of the spring 114 is fixedly connected to the outer surface of the pawl 115. The auxiliary structure 2 includes a fixing rod 201. A support member 202 is fixedly connected to the outer surface of the fixing rod 201. The inner surface of the support member 202 is slidably connected to the outer surface of the connecting rope 116. The outer surface of the fixing rod 201 is fixedly connected to the outer surface of the fixed cylinder 101.
[0027] The overall effect achieved by the entire Embodiment 2 is that when the subsequent user manually rotates the round cover 102 in the circular groove 110, the connecting rod 112 and the ratchet wheel 111 will be driven to rotate together. At this time, the pawl 115 will slide on the ratchet wheel 111. Through the mutual cooperation of the ratchet wheel 111 and the connecting rod 112, it is realized that the joint body 108 can rotate within a certain angle range after connection for subsequent use. And through the setting of the fixing rod 201 and the support member 202, it is realized that the connecting rope 116 can be supported, so that the subsequent user can normally pull the connecting rope 116.
[0028] Working principle: When in use, the user connects the external connecting wire to the joint body 108. After the connection is completed, the first electric push rod 103 extends or retracts to drive the positions of the connecting plate 104, compression spring 105, second electric push rod 106, rubber gasket 107 and the limiting member 109 to move back and forth. After adjusting to the position of the connection point, the limiting member 109 moves downward through the second electric push rod 106, so that the two limiting members 109 can approach each other. After moving to a certain position, the connection point can be strengthened to ensure a more stable connection and prevent loosening caused by the force generated during rotation in the use process. If rotation is required, the user pulls one of the connecting ropes 116, so that the pawl 115 can disengage from the ratchet wheel 111, and then rotates the round cover 102 to make it slide in the circular groove 110. When sliding, it drives the connecting rod 112 at the same time, and the connecting rod 112 drives the ratchet wheel 111 to rotate, so as to realize that it can rotate within a certain range after connection. Then, after rotating to a certain position, the connecting rope 116 can be released, and through the cooperation of the pawl 115 and the spring 114, the ratchet wheel 111 can be restricted for subsequent normal use.
[0029] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
