[0026] Schematic transition joint

[0027] refer to Figures 1 to 3 According to a preferred embodiment of the transition joint of the utility model, it should be noted that the transition joint includes a joint body 10, the joint body 10 has a first connection part 11, a bending part 12 and a second connection part 13, the first connection part 11 is perpendicular to the second connection part 13, and the two ends of the bending part 12 are respectively connected to the first connection part 11 and the second connection part 13, and the second connection part 13 and the bending part 12 are integrally formed, and the first connection part 11 is welded to the bending part 12. It is worth mentioning that the joint body 10 has a first opening 101, a cavity 102 and a second opening 103, the first opening 101 and the second opening 103 are both connected to the cavity 102, and the first opening 101 and the second opening 103 are also connected to the outside. The second opening 103 is located at the end of the second connection part 13 away from the bending part 12.

[0028] It should be noted that the connector body 10 also has a third connection portion 14, and the third connection portion 14 is welded to the end of the first connection portion 11 away from the bent portion 12, so that the third connection portion 14 and the first connection portion 11 form a whole. In addition, the first opening 101 is located at the end of the third connection portion 14 away from the first connection portion 11, and the cavity 102 also passes through the third connection portion 14. It is worth mentioning that the outer walls of the third connection portion 14, the first connection portion 11 and the second connection portion 13 are all provided with external threads.

[0029] Furthermore, the cross-sectional dimension of the third connection portion 14 is greater than the cross-sectional dimension of the first connection portion 11. It is worth mentioning that the third connection portion 14 is configured to be connected to the external panel 100, and its structure is as follows: Figure 1As shown, the external panel 100 has an assembly hole 200, and the third connection part 14 passes through the assembly hole 200, that is, the end of the third connection part 14 facing away from the first connection part 11 is located on the inner side of the above-mentioned panel. In addition, the transition joint also includes a lock nut 20, and the lock nut 20 and the third connection part 14 are located on the inner side of the external panel 100. It should be noted that after the conventional joint is fixed with the nut, its use angle cannot be adjusted, so there is a large limitation in use. Specifically, after the lock nut 20 is installed, it is generally impossible to adjust the angle of the joint by loosening the lock nut 20. Therefore, in view of the above technical problems, the utility model has been specially improved. Specifically, the transition joint also includes a locking member 30, and the locking member 30 is threadedly connected to the first connection part 11. The rotation direction of the external thread of the first connecting part 11 is opposite to that of the external thread of the third connecting part 14, that is, the tightening direction of the lock nut 20 is from left to right, and the tightening direction of the locking member 30 is from right to left. In addition, the locking member 30 is first placed on the first connecting part 11, and then the first connecting part 11 and the bending part 12 are welded.

[0030] It is worth mentioning that the locking member 30 has at least two oppositely arranged mounting grooves 301 on one side close to the curved portion 12, and an elastic block 40 is arranged in each of the mounting grooves 301, one end of the elastic block 40 contacts the bottom wall forming the mounting groove 301, and the other end abuts against the side of the curved portion 12 close to the first connecting portion 11. It should be noted that the elastic block 40 is configured to provide resistance to the locking member 30, that is, when the locking member 30 moves a predetermined distance in the direction close to the external plate, the third connecting portion 14 is limited by squeezing the two sides of the external plate through the lock nut 20 and the locking member 30. The locking piece 30 is located on the outside of the outer plate body, and the cross-sectional shape of the locking piece 30 is hexagonal, so that the user can clamp the wrench on the surface of the locking piece 30 to rotate the locking piece 30, and at least two elastic blocks 40 located on the right side of the locking piece 30 can provide resistance when the user loosens the above-mentioned locking piece 30 to prevent the user from loosening the locking piece 30 too many turns, thereby causing the transition joint to loosen. As a result, when the user deflects the transition joint by an excessively large angle, the transition joint will cause the above-mentioned second connection part 13 to face downward due to inertia problems. The provision of the two elastic blocks 40 can avoid such problems, that is, the user can slightly rotate the locking piece 30 to pry the second connection part 13 to adjust the second connection part 13, and at this time, the locking piece 30 and the lock nut 20 still have a certain clamping force, thereby preventing the second connection part 13 from swinging significantly. It should also be noted that the elastic block 40 can be inserted into the installation slot 301 by squeezing, and the user can manually adjust the position of the locking member 30 to facilitate the user to install the elastic block 40 .

[0031] Furthermore, the elastic block 40 can be implemented as rubber, and it should be noted that the side of the lock nut 20 close to the external plate body also has an annular groove 201, and the annular groove 201 is configured to ensure that one side of the lock nut 20 can fit the external plate body 200.

[0032] In summary, the transition joint based on the embodiment of the present application is explained, which provides the transition joint with advantages such as convenient joint angle adjustment, high practicality, and simple structure.

[0033] It is worth mentioning that in the embodiment of the present application, the transition joint has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the transition joint provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitating product promotion and use.
