Referring to fig. 1-8, the movable joint 100 of the present invention includes a first housing 110, a second housing 120, an inner locking mechanism 130, and an operating member 140. The first housing 110 and the second housing 120 are both hollow, and a first locking portion 111 is protruded on an inner wall of at least one of the first housing 110 and the second housing 120. The inner locking mechanism 130 includes a locking shaft 131, the locking shaft 131 is movably disposed in the first housing 110 and the second housing 120, a second locking portion 1311 corresponding to the first locking portion 111 is disposed on the locking shaft 131 in a protruding manner, the locking shaft 131 can move along the axial direction thereof to detachably engage the second locking portion 1311 with the first locking portion 111, so that the locking shaft 131 is in a locked state or an unlocked state, and when the locking shaft 131 is in the unlocked state, the first housing 110 and the second housing 120 can both rotate relative to the locking shaft 131. The operation member 140 is rotatably connected to one end of the locking shaft 131 and has a first position and a second position, when the operation member 140 is located at the first position, the locking shaft 131 can be driven to move along the axial direction thereof to enable the locking shaft 131 to be converted between a locking state and a releasing state, and when the operation member 140 is rotated to the second position, the operation member 140 abuts against the first housing 110 or the second housing 120, and at this time, the operation member 140 cannot drive the locking shaft 131 to move, so that the locking shaft 131 is maintained at the locking state, and the purpose of preventing misoperation is achieved.

The movable joint 100 of the present invention, its inner lock mechanism 130, can have different setting modes, and accordingly, it has different connection modes when connecting two components that need to be pivotally adjusted. For example, in one embodiment, the first and second housings 110 and 120 are provided with first locking portions 111 therein, and the locking shaft 131 is provided with second locking portions 1311 corresponding to the two first locking portions 111, respectively, so that when the locking shaft 131 is locked, the first and second housings 110 and 120 cannot rotate, and when the locking shaft 131 is unlocked, the first and second housings 110 and 120 can rotate relative to the locking shaft 131. In this embodiment, two components requiring pivotal adjustment may be connected to the first housing 110 and the second housing 120, respectively, or one of the two components may be connected to the first housing 110 and the second housing 120 at the same time, and the other may be connected to the locking shaft 131, so that the angle adjustment between the two components may be achieved when the locking shaft 131 is in the unlocked state.

In this embodiment, it is preferable that one of two components requiring pivotal adjustment be connected to the first and second housings 110 and 120 at the same time, so that the components connected to the first and second housings 110 and 120 cannot be rotated when the lock shaft 131 is in the locked state. As for the other component, it can be directly fixed to the locking shaft 131, so that the angle adjustment between the two components is realized only by the rotation of the first and second housings 110 and 120; alternatively, the angle adjustment may be performed by coupling a member to the lock shaft 131, and by preventing the member from rotating when the lock shaft 131 is locked and allowing the member to rotate when the lock shaft 131 is unlocked (see details later).

With continued reference to fig. 1-8, in an embodiment of the present invention, only the first locking portion 111 is protruded on the inner wall of the first housing 110, correspondingly, one end of the locking shaft 131 is provided with a second locking portion 1311 corresponding to the first locking portion 111, and the other end of the locking shaft 131 is provided with the operation member 140.

Further, since the locking shaft 131 is movably disposed along the axial direction thereof, the connection segment 131a and the component connected to the location also have a locking state and a releasing state, specifically, when the locking shaft 131 is in the locking state, the connection segment 131a and the component connected to the location are locked, and both the components cannot rotate, and when the locking shaft 131 moves to the releasing position, the connection segment 131a of the locking shaft 131 and the component connected to the location form a clearance fit, and at this time, the component can rotate relative to the locking shaft 131, and the first housing 110 and the second housing 120 can also rotate relative to the locking shaft 131, so that the angle adjustment between the two components can be realized. In this embodiment, the structure of the interlock mechanism 130 and the movable joint 100 can be greatly simplified.

Referring to fig. 2-3 and 6-8, in the present embodiment, to further simplify the structure of the movable joint 100 and the internal locking mechanism 130, the outer diameter of the locking shaft 131 is gradually changed along the axial direction thereof, and specifically, the outer diameter of the locking shaft 131 gradually increases from the end where the operating member 140 is located to the end where the second locking portion 1311 is located (see fig. 3). This structure is arranged, only the corresponding connection hole is needed to be opened on the component, that is, the hole diameter of the connection hole on the component corresponds to the outer diameter of the connection segment 131a of the locking shaft 131, so that when the locking shaft 131 is in the locking state, the end with larger outer diameter on the connection segment 131a is located in the connection hole to form locking, when the locking shaft 131 moves to the unlocking state, the second locking portion 1311 on the locking shaft is separated from the first locking portion 111, and simultaneously the part with smaller outer diameter on the connection segment 131a moves to the connection hole due to the movement, at this time, the component connected to the connection segment 131a can rotate relative to the locking shaft 131, and the components connected to the first housing 110 and the second housing 120 can also rotate, thereby realizing quick adjustment. With this structural arrangement of the locking shaft 131 in the present embodiment, no additional positioning structure is required between the connecting section 131a and the corresponding component, and therefore, the structure of the internal lock mechanism 130 is simplified and the unlocking operation is simplified.

In the present invention, the cross section of the locking shaft 131 may be semicircular, circular, square, trapezoidal or other polygonal structures, and the cross sectional shape thereof is not specifically limited. In a preferred embodiment, the cross-section is provided as a square, as shown in fig. 3, which both ensures stability in the locked condition and also makes machining easier.

In addition, a first latch 113 is further convexly arranged on the outer wall of the first housing 110, and is used for being clamped with other components, so that the connection stability is ensured.

As shown in fig. 3 and 6 to 8, the second locking portion 1311 protrudes in the radial direction of the locking shaft 131 and has a frustum shape, and the shape and the inner diameter of the inner wall of the first locking portion 111 correspond to the shape and the outer diameter of the second locking portion 1311, but the shapes of the first locking portion 111 and the second locking portion 1311 are not limited to this. Also, the outer wall of the second locking portion 1311 is provided with a plurality of engaging teeth 1312 at intervals in the radial direction thereof, that is, each engaging tooth 1312 protrudes in the radial direction of the locking shaft 131; correspondingly, the inner wall of the first locking portion 111 is concavely provided with an engaging groove 1111 engaged with the engaging protrusion 1312, and the engaging groove 1111 penetrates through one end of the first locking portion 111 far away from the blocking portion 1112 and is communicated with the first accommodating cavity 112. Thus, when the operation element 140 is forced to push the locking shaft 131 to move along the axial direction thereof, the second locking portion 1311 can slide into the first receiving cavity 112 to disengage from the first locking portion 111, at this time, the engaging protrusion 1312 disengages from the engaging recess 1111, and the locking shaft 131 is in the unlocking state, as shown in fig. 7; when the lock shaft 131 moves in the opposite direction in the axial direction, the second lock portion 1311 can be locked again in the first lock portion 111, the engagement protrusion 1312 can be slid again into the engagement recess 1111, and the lock shaft 131 is in the locked state, and as shown in fig. 6, the second lock portion 1311 cannot rotate relative to the first lock portion 111, that is, the lock shaft 131 cannot rotate relative to the first housing 110, due to the engagement of the engagement protrusion 1312 and the engagement recess 1111; in addition, in the process of sliding the second locking portion 1311 into the first locking portion 111, the end surface of the second locking portion 1311 abuts against the stopper 1112 to limit the stopper, and the second locking portion 1311 is prevented from being detached from the first locking portion 111. Understandably, the positions of the engaging teeth 1312 and the engaging grooves 1111 can be interchanged.
