Detailed ways

Referring to Figures 1 to 4, the utility model is a lockable rotary joint, including a left transition tube 1, a right transition tube 2, a left joint 3, a right joint 4 and a locking device, and the left joint 3 and the right joint 4 are pivotally connected. Together, the left joint 3 and the right joint 4 are provided with a connecting pipe 5, the left transition pipe 1 and the right transition pipe 2 are inserted in the connecting pipe 5, and the locking device is used to lock the connection between the left joint 3 and the right joint 4. The relative rotation between the left transition pipe 1 and the right transition pipe 2 can rotate relative to the connecting pipe 5; when in use, the left transition pipe 1 and the right transition pipe 2 are used to connect the parts to be connected, and the utility model adopting the above-mentioned structure is novel in structure, It is simple and practical, and does not affect the overall appearance of the product; the utility model can prevent children from pinching their fingers with random operations.

As shown in the figure, the locking device can adopt the following specific embodiments: including a locking lever 61 slidably arranged in the right transition tube 2, two locking levers arranged on the left joint 3 and the right joint 4 and cooperating with the locking lever 61 hole 62, spring 63, sliding sleeve 64, first stop bar 65 and second stop bar 66, the first elongated hole 67 and the first through hole 68 are arranged on the lock bar 61, and the lock hole 62 is not located On the axis of the connecting pipe 5, the right transition pipe 2 is provided with a second elongated hole 69 and a second through hole 70, the first stop rod 65 is inserted in the first elongated hole 67 and the second through hole 70, the second The second blocking rod 66 is inserted in the first through hole and the second elongated hole 69, the sliding sleeve 64 is sleeved on the right transition pipe 2, and the spring 63 is against the side of the first blocking rod 65 and the first elongated hole 67 on the wall.

The specific action principle of the utility model adopting the above-mentioned structure is as follows. In the locked state, the left joint 3 and the right joint 4 are in a straight line, the locking rod 61 is inserted into the two locking holes 62, the left joint 3 cannot rotate relative to the right joint 4, and the left The joint 3 and the right joint 4 cannot rotate relative to the left transition pipe 1 and the right transition pipe 2. At this time, the utility model cannot be folded; At this time, the left joint 3 can rotate relative to the right joint 4, and the utility model can be folded, and the right joint 4 can rotate relative to the right transition tube 2 (it is convenient for customers to choose upward or downward When it needs to be unfolded, turn the right joint 4 until it forms a straight line with the left joint 3, and then make the locking rod 61 enter the two locking holes 62 to complete the unfolding.

The above-mentioned embodiments are only preferred solutions of the utility model, and the utility model also has other implementation solutions. Those skilled in the art can also make equivalent modifications or replacements without departing from the spirit of the present utility model, and these equivalent modifications or replacements are all included in the scope set by the claims of the present application.
