Description

Technical Field

[0001] This utility model relates to the field of stabilizer accessories technology, specifically a stabilizer shaft structure. Background Technology

[0002] With the widespread use of handheld electronic devices such as smartphones and lightweight camcorders, handheld stabilizers designed to hold these devices and improve shooting stability have experienced rapid development. These stabilizers use a hinge structure to enable multi-angle rotation of the device, meeting users' shooting needs in different scenarios, such as vertical live streaming with a smartphone or low-angle shooting with a camcorder.

[0003] However, the hinge structure of current handheld stabilizers on the market has significant shortcomings in terms of stability, mainly reflected in:

[0004] On the one hand, the angle fixation is unreliable. Existing hinges mostly rely on a single spring clamping or friction plate abutment to fix the angle, which is difficult to provide a continuous and stable locking force. After long-term use, the angle is prone to shift due to component wear, or even sudden loosening, which may cause mobile phones, cameras and other devices to shake or fall off.

[0005] On the other hand, the limiting support effect is poor. Existing hinges lack an effective rigid limiting design and mostly rely on the clearance fit between the shaft core and connecting parts for limiting. When subjected to external impact, the hinge is prone to unexpected rotation, affecting shooting results, accelerating component wear, and further reducing stability. Utility Model Content

[0006] In order to overcome the shortcomings of existing technical solutions, this utility model provides a stabilizer shaft structure that can effectively solve the technical problem of insufficient stability of the shaft currently used in stabilizers.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A stabilizer shaft structure includes an intermediate connector, two rotatable flip members respectively connected to both ends of the intermediate connector, and a locking assembly for locking and fixing the position of the flip members.

[0009] The intermediate connector includes two parallel connecting pieces and a support column fixed between the two connecting pieces. The support column includes an upper support column and a lower support column that are distributed longitudinally.

[0010] The flipping component includes a shaft core and a fixing frame fixed to both ends of the shaft core. The fixing frame achieves flipping by having the shaft core inserted through two connecting pieces.

[0011] The locking assembly includes a gear that rotates synchronously on the outside of the shaft core, an integral cam and a spring that are integrated between the two shaft cores. The end face of the gear is provided with several limiting slots. The two ends of the integral cam are respectively provided with limiting protrusions that are fixed in multiple positions with the corresponding limiting slots. The spring is sleeved on the end of the shaft core away from the gear, and the spring provides elastic force to push the integral cam toward the gear end to achieve fixation.

[0012] The gear has an upper contact portion facing the upper support column and a lower contact portion facing the lower support column on its outer side. When the fixing frame is flipped upward, the limiting protrusion is fixed in the corresponding limiting slot, and the upper contact portion is attached to the outer side of the upper support column. When the fixing frame is flipped downward, the limiting protrusion is fixed in the corresponding limiting slot, and the lower contact portion is attached to the outer side of the lower support column.

[0013] Furthermore, the upper support column and the lower support column are fixed in the middle of the connecting piece, and the two ends of the integrated cam are provided with holes for respectively embedding the upper support column and the lower support column.

[0014] Furthermore, the fixing frame has sleeve holes at both ends for fixing the shaft core, and the shaft core has T-shaped sleeves at both ends to prevent the fixing frame from detaching.

[0015] Furthermore, the two ends of the shaft are fitted with shims located between the fixing frame and the connecting piece, and the shims and the connecting piece are provided with circular holes to facilitate the rotation of the shaft.

[0016] Furthermore, the upper and lower fitting parts are respectively provided with arc surfaces that have the same curvature as the outer side of the support column.

[0017] Furthermore, the end of the fixing frame away from the shaft core is provided with several mounting holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The stabilizer shaft structure provided by this utility model achieves precise fixation of the flipping component in multiple positions by cooperating with the limiting protrusion of the integrated cam and several limiting slots of the gear, and with the help of the continuous thrust provided by the spring. This greatly improves the adjustment flexibility and can meet the multi-angle use needs in different scenarios. At the same time, when the fixing frame flips and fixes, the upper and lower contact parts of the gear are simultaneously and tightly attached to the outer side of the corresponding support column, forming a secondary limit on the basis of position fixation. This effectively enhances the structural stability, avoids angle deviation, and ensures the reliable performance of the stabilizer during operation. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figure 1-6 As shown, this utility model discloses a stabilizer shaft structure, which is mainly used in handheld electronic device stabilizers to achieve stable clamping and multi-angle adjustment of devices such as mobile phones and cameras. The stabilizer shaft structure mainly consists of three parts: a middle connecting part 1, a flipping part 2, and a locking assembly 3. Its structure is ingeniously designed, and through the coordinated cooperation of multiple parts, it achieves a stable and reliable multi-level flipping positioning function.

[0040] The intermediate connector 1 serves as the supporting foundation of the entire structure, comprising two parallel connecting plates 101 and a support column 102 fixed between the two connecting plates 101. The support column 102 adopts a longitudinally distributed split design, specifically divided into an upper support column 1021 and a lower support column 1022, which respectively undertake the functions of limiting and supporting during the flipping process. The connecting plates 101 are made of high-strength alloy material to ensure structural stability, and their thickness is set according to the load-bearing requirements of the stabilizer. The upper support column 1021 and the lower support column 1022 are vertically fixed at the middle position of the connecting plates 101, and the distance between them is adapted to the movement trajectory of the flipping component 2 to ensure no jamming during the flipping process.

[0041] The flipping component 2 is the core component for realizing the stabilizer's flipping action, including a shaft core 201 and a fixing bracket 202 fixed to both ends of the shaft core 201. The fixing bracket 202 passes between two connecting pieces 101 through the shaft core 201, thereby enabling free flipping around the shaft core 201. The shaft core 201 is made of high-strength steel and its surface is chrome-plated to improve wear resistance and oxidation resistance. The fixing bracket 202 has sleeve holes 2021 at both ends. After the two ends of the shaft core 201 pass through the sleeve holes 2021, they are fixed by welding or bolts to ensure a firm connection between the two.

[0042] To prevent the fixing frame 202 from detaching from both ends of the shaft core 201, T-shaped sleeves 203 are fitted onto both ends of the shaft core 201. The T-shaped sleeves 203 are made of elastic rubber, serving both as a limiting element and to cushion vibrations during the flipping process. Furthermore, a shim sleeve 204 is fitted between the fixing frame 202 and the connecting piece 101. The shim sleeve 204 has a circular hole 2041 through which the shaft core 201 passes, ensuring smooth rotation of the shaft core 201 and preventing direct friction between the fixing frame 202 and the connecting piece 101. Several mounting holes 2022 are provided at the end of the fixing frame 202 away from the shaft core 201 for connecting other functional components of the stabilizer. The number and diameter of the mounting holes 2022 can be adjusted according to actual installation requirements.

[0043] The locking assembly 3 is used to fix the flipping component 2 at different angles. It includes a gear 301 that is sleeved on the outside of the shaft core 201 and rotates synchronously, an integral cam 302 that is sleeved between the two shaft cores 201, and a spring 303. The end face of the gear 301 has several limiting slots 3011, which are evenly distributed. The included angle between two adjacent limiting slots 3011 is determined according to the required number of gears to achieve multi-gear adjustment. The two ends of the integral cam 302 are respectively provided with limiting protrusions 3021 that are adapted to the corresponding limiting slots 3011. When the limiting protrusions 3021 are engaged in the limiting slots 3011, the flipping component 2 can be fixed. Spring 303 is sleeved on the end of shaft 201 away from gear 301. One end of spring 303 abuts against connecting piece 101 and the other end abuts against integrated cam 302, providing elastic force for integrated cam 302 to push one end of gear 301, ensuring that the limiting protrusion 3021 and the limiting groove 3011 are tightly fitted.

[0044] The gear 301 has an upper fitting portion 3012 and a lower fitting portion 3013 on its outer side. The upper fitting portion 3012 is in the same direction as the upper support column 1021, and the lower fitting portion 3013 is in the same direction as the lower support column 1022. Both the upper fitting portion 3012 and the lower fitting portion 3013 have arc surfaces with the same curvature as the outer side of the support column 102. This design ensures that when the flipping component 2 is fixed, the upper fitting portion 3012 fits tightly against the outer side of the upper support column 1021, and the lower fitting portion 3013 fits tightly against the outer side of the lower support column 1022, further improving the stability of the structure. The integrated cam 302 also has holes 3022 at both ends for respectively embedding the upper support column 1021 and the lower support column 1022. The size of the holes 3022 matches the diameter of the upper support column 1021 and the lower support column 1022, ensuring that the integrated cam 302 does not shift during movement.

[0045] When in use, the working principle of the stabilizer shaft structure is mainly based on the cooperation of gears and cams and the elastic force of springs to realize the multi-level adjustment and fixation of the flipping part 2.

[0046] When the fixing bracket 202 needs to be flipped upwards, an external force is applied to overcome the elastic force of the spring 303, causing the integrated cam 302 to move away from the gear 301. At this time, the limiting protrusion 3021 disengages from the limiting slot 3011. As the fixing bracket 202 flips upwards, the shaft core 201 drives the gear 301 to rotate synchronously. When it rotates to the appropriate position, the external force is released, and under the action of the spring 303, the integrated cam 302 pushes towards one end of the gear 301, and the limiting protrusion 3021 is engaged in the corresponding limiting slot 3011 for fixation. At the same time, the upper fitting part 3012 fits against the outer side of the upper support column 1021 to achieve further limiting fixation. At this time, the fixing bracket 202 is stable in the upward-flipped position.

[0047] When the fixing bracket 202 needs to be flipped downwards, an external force is applied to move the integrated cam 302 away from the gear 301, and the limiting protrusion 3021 disengages from the current limiting slot 3011. The downward flipping of the fixing bracket 202 drives the shaft core 201 and the gear 301 to rotate. After reaching the desired position, under the action of the spring 303, the limiting protrusion 3021 is locked into another limiting slot 3011, and the lower fitting part 3013 fits against the outer side of the lower support column 1022 to achieve limiting, and the fixing bracket 202 is then stabilized in the downward flipped position.

[0048] Compared with traditional technologies, the stabilizer shaft structure provided by this technical solution uses the limiting protrusion of the integrated cam to cooperate with several limiting slots of the gear, and with the help of the continuous thrust provided by the spring, to achieve precise fixation of the flipping part in multiple positions, which greatly improves the adjustment flexibility and can meet the multi-angle use needs in different scenarios. At the same time, when the fixing frame flips and fixes, the upper and lower contact parts of the gear are simultaneously and tightly attached to the outer side of the corresponding support column, forming a secondary limit on the basis of fixed position, which effectively enhances the structural stability, avoids angle deviation, and ensures the reliable performance of the stabilizer during operation.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
