Description

Technical Field

[0001] This utility model relates to the technical field of steering connection mechanisms, and in particular to a retractable spherical steering connection mechanism. Background Technology

[0002] In many technical fields, connecting mechanisms are often needed to achieve the movable connection between two components, and these mechanisms must combine steering adjustment function with portability to adapt to different usage scenarios and facilitate storage. Existing steering connection mechanisms (such as hinges and ball joints) mostly lack telescopic function, have a fixed volume when not in use, and occupy a large space; some telescopic mechanisms lack steering flexibility, or the two structures interfere with each other, resulting in complicated operation and poor storage.

[0003] Therefore, the industry urgently needs a connection mechanism that is simple in structure, stable in connection, flexible in direction, and retractable when not in use, thereby saving space and making it easy to carry, in order to solve the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a retractable spherical steering connection mechanism with steering and retraction functions.

[0005] The technical solution of this utility model:

[0006] A retractable spherical steering connection mechanism includes a first sleeve and a second sleeve. The first sleeve is connected to the second sleeve via a spherical connector. The spherical connector includes a connecting ball, on which two transverse support rods and two longitudinal support rods are provided. The first sleeve has two first closed grooves that cooperate with the transverse support rods, and the second sleeve has two second closed grooves that cooperate with the longitudinal support rods.

[0007] Furthermore, the mating end of the first sleeve and the spherical connector has two first arc-shaped recesses, and the mating end of the second sleeve and the spherical connector has two second arc-shaped recesses.

[0008] Furthermore, the inner diameter of the first sleeve is larger than the outer diameter of the second sleeve, and the inner diameter of the second sleeve is larger than the outer diameter of the connecting ball; the first sleeve has two first open grooves for sliding of the longitudinal support rod, and the second sleeve has two second open grooves for sliding of the transverse support rod.

[0009] Furthermore, the opening of the first open groove is located at the mating end of the first sleeve and the spherical connector, and the opening of the second open groove is located at the mating end of the second sleeve and the spherical connector.

[0010] Furthermore, the first open groove and the first closed groove are distributed at 90° intervals, and the second open groove and the second closed groove are distributed at 90° intervals.

[0011] Furthermore, both the longitudinal support rod and the transverse support rod are connected to the connecting ball thread.

[0012] Furthermore, the end of the transverse support rod has a first stop block, the outer diameter of which is greater than the width of the first closed groove; the end of the longitudinal support rod has a second stop block, the outer diameter of which is greater than the width of the second closed groove.

[0013] The beneficial effects of this utility model are:

[0014] (1) Through the cooperation of the transverse support rod and the first closed slide groove, the first sleeve can rotate around the transverse support rod, and thus the component connected to the first sleeve can rotate around the transverse support rod; through the cooperation of the longitudinal support rod and the second closed slide groove, the second sleeve can rotate around the longitudinal support rod, and thus the component connected to the second sleeve can rotate around the longitudinal support rod. When turning is required, since the component connected to the first sleeve can rotate around the transverse support rod and the component connected to the second sleeve can rotate around the longitudinal support rod, the flexibility during turning is improved, and it can pass smoothly when passing through narrow corners.

[0015] (2) The first arc-shaped concave part can provide turning space when the part connected to the second sleeve rotates, and the second arc-shaped concave part can provide turning space when the part connected to the first sleeve rotates.

[0016] (3) Since the inner diameter of the first sleeve is larger than the outer diameter of the second sleeve, and the inner diameter of the second sleeve is larger than the outer diameter of the connecting ball, the second sleeve and the connecting ball can be retracted into the first sleeve. During this process, the longitudinal support rod slides into the first open groove and the transverse support rod slides into the second open groove, which plays a telescopic function, so that space can be saved and it is convenient to carry when not in operation.

[0017] This utility model has a simple structure, stable connection, flexible turning capability, and can be extended and retracted for storage when not in use, thereby saving space and making it easy to carry. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, this utility model provides a first embodiment of a retractable spherical steering connection mechanism, including a first sleeve 1 and a second sleeve 2. The first sleeve 1 is connected to the second sleeve 2 via a spherical connector 3. The spherical connector 3 includes a connecting ball 31, on which two transverse support rods 32 and two longitudinal support rods 33 are provided. The first sleeve 1 has two first closed grooves 11 that cooperate with the transverse support rods 32, and the second sleeve 2 has two second closed grooves 21 that cooperate with the longitudinal support rods 33.

[0024] In this embodiment, the end of the first sleeve 1 away from the spherical connector 3 is connected to one of the components, and the end of the second sleeve 2 away from the spherical connector 3 is connected to the other component.

[0025] The first sleeve 1 can rotate around the first sleeve 1 by the cooperation of the transverse support rod 32 and the first closed slide groove 11. Similarly, the second sleeve 2 can rotate around the second sleeve 1 by the cooperation of the longitudinal support rod 33 and the second closed slide groove 21. This allows the second sleeve 2 to rotate around the longitudinal support rod 33, and consequently, the components connected to the second sleeve 2 to rotate around the longitudinal support rod 33. When turning is required, the components connected to the first sleeve 1 can rotate around the transverse support rod 32, and the components connected to the second sleeve 2 can rotate around the longitudinal support rod 33, thus improving maneuverability and allowing for smooth passage through narrow corners.

[0026] Based on the first embodiment, this utility model provides a second embodiment of a retractable spherical steering connection mechanism. The first sleeve 1 and the spherical connector 3 have two first arc-shaped recesses 12 at their mating ends, and the second sleeve 2 and the spherical connector 3 have two second arc-shaped recesses 22 at their mating ends. The first arc-shaped recesses 12 can provide steering space when the component connected to the second sleeve 2 rotates, and the second arc-shaped recesses 22 can provide steering space when the component connected to the first sleeve 1 rotates.

[0027] Based on any of the above embodiments, this utility model provides a third embodiment of a retractable spherical steering connection mechanism. The inner diameter of the first sleeve 1 is larger than the outer diameter of the second sleeve 2, and the inner diameter of the second sleeve 2 is larger than the outer diameter of the connecting ball 31. The first sleeve 1 has two first open grooves 13 for sliding of the longitudinal support rod 33, and the second sleeve 2 has two second open grooves 23 for sliding of the transverse support rod 32. Since the inner diameter of the first sleeve 1 is larger than the inner diameter of the second sleeve 2, and the inner diameter of the second sleeve 2 is larger than the inner diameter of the connecting ball 31, the second sleeve 2 and the connecting ball 31 can retract into the first sleeve 1. During this process, the longitudinal support rod 33 slides into the first open groove 13, and the transverse support rod 32 slides into the second open groove 23, achieving a telescopic function, which saves space and is convenient to carry when not in operation.

[0028] Based on any of the above embodiments, this utility model provides a fourth embodiment of the retractable spherical steering connection mechanism. The opening of the first open slide groove 13 is located at the mating end of the first sleeve 1 and the spherical connector 3, facilitating the longitudinal support rod 33 to slide into the first open slide groove 13. The opening of the second open slide groove 23 is located at the mating end of the second sleeve 2 and the spherical connector 3, facilitating the transverse support rod 32 to slide into the second open slide groove 23.

[0029] Based on the third and fourth embodiments, this utility model provides a fifth embodiment of the retractable spherical steering connection mechanism, wherein the first open slide groove 13 and the first closed slide groove 11 are distributed at 90° intervals, and the second open slide groove 23 and the second closed slide groove 21 are distributed at 90° intervals.

[0030] Based on any of the above embodiments, the present invention provides a sixth embodiment of the retractable spherical steering connection mechanism, wherein the longitudinal support rod 33 and the transverse support rod 32 are both threadedly connected to the connecting ball 31, which facilitates the assembly and disassembly of the longitudinal support rod 33 and the transverse support rod 32.

[0031] Based on any of the above embodiments, this utility model provides a seventh embodiment of the retractable spherical steering connection mechanism, wherein the end of the transverse support rod 32 has a first stop 34, the outer diameter of the first stop 34 being larger than the width of the first closed slide groove 11, to prevent the transverse support rod 32 from disengaging from the first closed slide groove 11; the end of the longitudinal support rod 33 has a second stop 35, the outer diameter of the second stop 35 being larger than the width of the second closed slide groove 21, to prevent the longitudinal support rod 33 from disengaging from the first closed slide groove 11.

[0032] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
