Description

Technical Field

[0001] The utility model relates to the technical field of rotating shaft bolts, and more specifically, to a rotating shaft bolt for a movable joint. Background Art

[0002] In order to be able to imitate the dynamic effects of the human body and better display corresponding goods (such as clothes, etc.), bionic models are provided with movable joints at parts such as arms, feet, and palms. In the prior art, movable joints used in bionic models all include a first flange and a second flange. A connecting bolt shaft is provided on the second flange so that the first flange can be assembled thereon and relative rotation of the two flanges can be achieved. Thus, the bionic model can pose in different postures.

[0003] Among them, the patent with the publication number CN205677969U discloses a rotating shaft bolt for a movable joint of a bionic model. The head of the rotating shaft bolt is provided with a cylindrical connecting head, the tail is provided with a thread, a turntable is provided below the connecting head, and at least one bump is provided on the lower surface of the turntable;

[0004] When this structure is in use, the upper end of the spring abuts against the turntable through the upper end cover (or, according to actual design requirements, it can also abut against the second flange), and the lower end of the spring abuts against the nut through the lower end cover to meet the usage requirement that the rotating shaft bolt and the turntable are always closed. However, it is difficult to achieve the requirements of multi-angle adjustment or axial fixation during use, resulting in limitations in the use of the device. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a rotating shaft bolt for a movable joint, aiming to solve the problems raised in the above-mentioned background art.

[0006] To achieve the above objective, the present utility model provides the following technical solution: A rotating shaft bolt for a movable joint, including a cross bar, and a limit adjustment assembly is arranged on the cross bar;

[0007] The limit adjustment assembly includes a connecting head fixedly connected to one end of the cross bar, and a limit sleeve is sleeved outside the connecting head;

[0008] A cushion block is rotatably connected inside the connecting head, a ball block is arranged at one end of the cushion block, an extension rod is fixedly arranged on the ball block, an external thread is provided on the outside of the connecting head, and the limit sleeve is threadedly connected to the external thread;

[0009] It can be seen that in the above technical solution, with the cross bar as the support point, the extension rod can be adjusted at multiple angles between the clamping plates through the ball block, so as to adjust the angle of the extension rod at the end of the cross bar. At the same time, by rotating the limit sleeve, the position of the limit sleeve on the connector can be adjusted through the external thread, so that the limit sleeve can extend to the outside of the extension rod and be sleeved on the nylon support sleeve, realizing the function of limiting the nylon support sleeve and the extension rod. Subsequently, the extension rod and the cross bar can be on the same axis, making it easy for two adjacent bionic joints to only rotate and not adjust the angle;

[0010] Optionally, in a possible implementation manner, a plurality of clamping plates are fixedly arranged on the cushion block, and each clamping plate is located outside the ball block. The vertical cross-sectional shapes of the clamping plate and the ball block are both set as arcs, and the ball block extends to one side of the clamping plate and is slidably connected to the clamping plate. A limit nut is threadedly connected to the outside of the extension rod. One end of the extension rod is sleeved with a nylon support sleeve, and the nylon support sleeve is matched with the limit sleeve. The nylon support sleeve is fixed at one end of the extension rod;

[0011] It can be seen that in the above technical solution, by rotating the limit nut, the limit nut approaches the clamping plate, causing the clamping plate to deform under force and clamp the ball block, increasing the friction between the ball block and the clamping plate, so that the ball block cannot rotate between the clamping plates, and then realizing the function of axially locking the cross bar and the extension rod.

[0012] The technical effects and advantages of the present utility model:

[0013] By setting the limit adjustment component, compared with the prior art, through the corresponding cooperation of each structure, with the cross bar as the support point, the extension rod can be adjusted at multiple angles between the clamping plates through the ball block, so as to adjust the angle of the extension rod at the end of the cross bar;

[0014] At the same time, by rotating the limit sleeve, the position of the limit sleeve on the connector can be adjusted through the external thread, so that the limit sleeve can extend to the outside of the extension rod and be sleeved on the nylon support sleeve, realizing the function of limiting the nylon support sleeve and the extension rod. Subsequently, the extension rod and the cross bar can be on the same axis, making it easy to lock two adjacent bionic joints;

[0015] And by rotating the limit nut, the limit nut approaches the clamping plate, causing the clamping plate to deform under force and clamp the ball block, increasing the friction between the ball block and the clamping plate, so that the ball block cannot rotate between the clamping plates, and then realizing the function of axially locking the cross bar and the extension rod.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] As shown in the attached Figures 1-5The rotating shaft bolt of the movable joint shown can be adjusted at multiple angles between each splint 5 through the ball block 6 by means of the extension rod 7 via the limit adjustment assembly provided on the cross bar 1, so as to adjust the angle of the extension rod 7 at the end of the cross bar 1. At the same time, by rotating the limit sleeve 3, the position of the limit sleeve 3 can be adjusted on the connecting head 2 through the external thread 10, so that the limit sleeve 3 can extend to the outside of the extension rod 7 and be sleeved on the nylon support sleeve 9, realizing the function of limiting the nylon support sleeve 9 and the extension rod 7. Subsequently, the extension rod 7 and the cross bar 1 can be on the same axis. It is easy for two adjacent bionic joints to only rotate and cannot adjust the angle, and the specific structure of the assembly is as follows;

[0025] The limit adjustment assembly includes a connecting head 2 fixedly connected to one end of the cross bar 1, and a limit sleeve 3 is sleeved on the outside of the connecting head 2;

[0026] A cushion block 4 is rotatably connected inside the connecting head 2. One end of the cushion block 4 is provided with a ball block 6. An extension rod 7 is fixedly arranged on the ball block 6. External threads 10 are provided on the outside of the connecting head 2, and the limit sleeve 3 is threadedly connected with the external threads 10;

[0027] A plurality of splints 5 are fixedly arranged on the cushion block 4, and each splint 5 is located outside the ball block 6. The vertical cross-sectional shapes of the splint 5 and the ball block 6 are both set as arcs, and the ball block 6 extends to one side of the splint 5 and is slidably connected with the splint 5. A limit nut 8 is threadedly connected to the outside of the extension rod 7. A nylon support sleeve 9 is sleeved on one end of the extension rod 7. The nylon support sleeve 9 matches the limit sleeve 3, and the nylon support sleeve 9 is fixed at one end of the extension rod 7.

[0028] When in use according to the above structure, the staff installs the device on the bionic joint. With the cross bar 1 as the support point, the extension rod 7 can be adjusted at multiple angles between each splint 5 through the ball block 6, so as to adjust the angle of the extension rod 7 at the end of the cross bar 1;

[0029] At the same time, by rotating the limit sleeve 3, the position of the limit sleeve 3 can be adjusted on the connecting head 2 through the external thread 10, so that the limit sleeve 3 can extend to the outside of the extension rod 7 and be sleeved on the nylon support sleeve 9, realizing the function of limiting the nylon support sleeve 9 and the extension rod 7. Subsequently, the extension rod 7 and the cross bar 1 can be on the same axis. It is easy for two adjacent bionic joints to only rotate and cannot adjust the angle;

[0030] And by rotating the limit nut 8, the limit nut 8 moves closer to the splint 5, so that the splint 5 deforms under force and clamps the ball block 6, increasing the friction between the ball block 6 and the splint 5, making the ball block 6 unable to rotate between each splint 5, and subsequently realizing the function of axially locking the cross bar 1 and the extension rod 7.

[0031] Different from the prior art, the present application discloses a rotating shaft bolt of a movable joint. Through the extension rod 7, it can be adjusted at multiple angles between each clamping plate 5 via the ball block 6, thereby realizing the adjustment of the angle of the extension rod 7 at the end of the cross bar 1. At the same time, through the rotation of the limit sleeve 3, the position of the limit sleeve 3 on the connecting head 2 is adjusted via the external thread 10, so that the limit sleeve 3 can extend to the outside of the extension rod 7 and be sleeved on the nylon support sleeve 9, realizing the function of limiting the nylon support sleeve 9 and the extension rod 7. Subsequently, the extension rod 7 and the cross bar 1 can be on the same axis line, making it easy for two adjacent bionic joints to only rotate and not adjust the angle.

[0032] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
