Description

Technical Field

[0001] The present invention relates to the technical field of locking mechanisms, and in particular to a one-button expansion locking mechanism. Background Art

[0002] One-touch deployment and locking mechanisms are commonly used in photographic equipment, aerospace, drones, packaging, and other fields. Their function is to achieve rapid deployment and reliable locking through simple operation, thereby improving efficiency, ensuring stable operation of the equipment, enhancing safety, facilitating automation, and improving overall performance.

[0003] In actual work, the existing one-touch deployment and locking mechanism can meet the basic needs of photography by using the bracket legs and the card slot, but it still has the following problems:

[0004] Common photographic equipment usually requires the folding bracket to be gradually opened to support the camera equipment. During the opening and folding process, the disassembly and assembly process is relatively cumbersome, which affects the efficiency of the use of the photographic equipment. For this reason, this application provides a one-button unfolding locking mechanism to meet the needs. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and provide a one-button deployment locking mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a one-touch expansion locking mechanism, comprising a telescopic plate and a fixing rod disposed on the top of the telescopic plate, wherein a fourth groove is formed on the side of the fixing rod, and further comprising:

[0007] A folding assembly, the folding assembly comprising a fixing seat mounted on a side of the telescopic plate, a driving connecting rod being provided on a side of the fixing seat, a driven connecting rod being rotatably connected to a side of the driving connecting rod, one end of the driving connecting rod being rotatably connected to a first mounting seat, and one end of the driven connecting rod being rotatably connected to a second mounting seat;

[0008] A drive assembly, the drive assembly comprising a protective shell disposed at the bottom of the fixed rod, the bottom of the protective shell being rotatably connected to an ascending sleeve and a descending sleeve;

[0009] The extension component includes a folding plate arranged in the inner cavity of the telescopic plate, and a handle is fixed on the outer surface of the folding plate.

[0010] Furthermore, a sliding groove is provided on the side of the fixing seat, one end of the driving connecting rod extends to the inner cavity of the sliding groove, and one end of the driving connecting rod is slidingly connected to the inner cavity of the sliding groove.

[0011] The technical effect of adopting the above technical solution is: a slide groove is opened on the side of the fixed seat, the inner wall surface is highly smooth, which effectively reduces the friction resistance, and one end of the driving connecting rod has a good size adaptability with the inner cavity of the slide groove, and a clearance fit method is adopted so that one end of the driving connecting rod can slide stably in the inner cavity of the slide groove. This structure can ensure that the driving connecting rod has good guidance during movement, effectively avoids shaking and deviation, and can withstand a certain lateral force, thereby ensuring the reliability and stability of the operation of the entire mechanical transmission system.

[0012] Furthermore, the side surface of the driven connecting rod away from one end of the second mounting seat is rotatably connected to a fixing block.

[0013] The technical effect of adopting the above technical solution is: the side of the driven connecting rod away from the second mounting seat is rotatably connected with a fixed block. This design realizes a flexible movable connection. The fixed block is made of high-strength wear-resistant material and is connected to the driven connecting rod through a bearing, which effectively reduces the rotational friction and ensures a smooth rotation process. This rotational connection method gives the driven connecting rod the ability to rotate freely at multiple angles, so that it can flexibly adjust its posture according to actual working conditions in mechanical transmission and reduce motion interference. In addition, the connection structure can effectively disperse stress, avoid excessive local force, significantly improve the overall stability and durability of the machine, and ensure long-term stable operation of the equipment.

[0014] Furthermore, a sliding rod is fixed to the bottom of the fixing rod.

[0015] The technical effect of adopting the above technical solution is: when the fixed rod moves downward, the sliding rod and the first groove form a precise match, ensuring smooth and unobstructed motion transmission. Under the coordinated action of the sliding rod and the first groove, the descending sleeve can achieve clockwise movement. This design realizes the effective conversion of the direction and trajectory of mechanical movement, converting vertical movement into rotational movement.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] By providing a fourth groove, the motion trajectory of the fixed rod can be limited, and a precise guide system is constructed for the fixed rod, which reduces shaking and offset, ensures the stability and accuracy of mechanical movement, and improves the operating accuracy of the overall structure. By providing a fixed seat, it is possible to provide stable support for the driving connecting rod, disperse the force, enhance the bearing capacity of the mechanical structure, and extend the service life of the equipment. By rotating the driven connecting rod connected to the side of the driving connecting rod, the telescopic plate can be assisted to complete smooth folding and unfolding movements, optimizing the motion transmission efficiency. Through the cooperation of the first mounting seat and the second mounting seat, power and support can be provided to the driving connecting rod and the driven connecting rod, ensuring the reliability of mechanical operation. The protective shell tightly wraps the rising sleeve, the descending sleeve and the fixed rod, effectively preventing dust and collision, and reducing component loss. Through the cooperation of the rising sleeve and the descending sleeve, when the fixed rod is pressed downward, the vertical movement of the fixed rod can be converted into a lateral expansion force of the telescopic plate, achieving efficient deployment. By providing a handle, the folding plate can be easily pulled out, improving operational convenience and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1 - Figure 6 As shown, this embodiment provides a technical solution: a one-touch expansion locking mechanism, including a telescopic plate 1 and a fixing rod 11 provided on the top of the telescopic plate 1, a fourth groove 12 is provided on the side of the fixing rod 11, and further comprising:

[0031] The folding assembly 2 includes a fixing base 21 mounted on the side of the telescopic plate 1. A driving connecting rod 22 is provided on the side of the fixing base 21. A driven connecting rod 24 is rotatably connected to the side of the driving connecting rod 22. One end of the driving connecting rod 22 is rotatably connected to a first mounting base 26. One end of the driven connecting rod 24 is rotatably connected to a second mounting base 27.

[0032] The driving assembly 3 includes a protective shell 31 disposed at the bottom of the fixed rod 11, and the bottom of the protective shell 31 is rotatably connected to a rising sleeve 32 and a descending sleeve 33;

[0033] The extension component 4 includes a folding plate 41 arranged in the inner cavity of the telescopic plate 1, and a handle 43 is fixed to the outer surface of the folding plate 41. A slide groove 23 is provided on the side of the fixing seat 21, and one end of the driving connecting rod 22 extends into the inner cavity of the slide groove 23. One end of the driving connecting rod 22 is slidably connected to the inner cavity of the slide groove 23, and the driven connecting rod 24 is rotatably connected to the side of the second mounting seat 27 and is connected to the fixing block 25. By providing the fourth groove 12, the movement trajectory of the fixing rod 11 can be effectively limited, and deviation can be avoided to a great extent, ensuring the stability and reliability of the mechanical operation. The handle design at the top of the fixing rod 11 is ergonomic, not only easy to operate, but also can accurately transmit the force when pressed downward. When it is necessary to support the camera equipment, by pressing the fixing rod 11 downward, the ring 38 can be prompted to drive the first mounting seat 26 and one end of the driving connecting rod 22 to Upward movement, in the process of driving the connecting rod 22 to move upward, through the cooperation of the fixed seat 21 and the first mounting seat 26, the driving connecting rod 22 can drive the driven connecting rod 24 to perform cross-expansion movement along the center point, and then can push the telescopic plate 1 to move quickly in the direction away from the protective shell 31, realizing one-button expansion and efficient operation, greatly saving operation time and improving ease of use. After the expansion is completed, the handle 43 is pulled downward to gradually pull out the folding plate 41, and the vertical length of the telescopic plate 1 is easily extended, realizing flexible height adjustment, adapting to the support requirements of equipment at different heights, and enhancing the versatility and practicality of the device. At the same time, the slide groove 23 opened on the side of the fixed seat 21 can accurately compensate for the displacement changes of the driving connecting rod 22 during the movement, effectively avoiding wear or damage of components caused by position offset, extending the service life of the equipment, and ensuring the long-term stable operation of the mechanical structure.

[0034] Furthermore, if Figure 4As shown: a sliding rod 34 is fixed to the bottom of the fixed rod 11, and a second groove 36 and a first groove 35 are respectively opened on the outer surfaces of the rising sleeve 32 and the descending sleeve 33. A limiting frame 37 is fixed to the top of the inner cavity of the protective shell 31, and a collar 38 is slidably connected to the inner cavity of the second groove 36. The outer surface of the collar 38 is fixed to the side of the first mounting seat 26, and the side of the descending sleeve 33 is fixed to the inner wall of the rising sleeve 32. At the same time, by making the spiral shapes of the first groove 35 and the second groove 36 opposite, the vertical movement of the fixed rod 11 can be cleverly converted into the rotational movement of the sleeve and the vertical movement of the collar 38. When the fixed rod 11 moves downward, the sliding rod 34 slides along the inner cavity of the first groove 35, driving the descending sleeve 33 and the rising sleeve 32 to rotate clockwise. This spiral transmission method not only improves The smoothness of movement also achieves efficient force transmission through the mechanical structure. During the movement of the fixed rod 11, the fourth groove 12 opened on the outer surface of the protective shell 31 can limit its movement trajectory to prevent it from deflecting or shaking during movement, ensuring that the entire transmission process is stable and reliable. When the rising sleeve 32 rotates clockwise, the second groove 36 is used to drive the ring 38 to move upward, and then the first mounting seat 26 drives one end of the driving connecting rod 22 to move upward synchronously, forming a coherent and efficient linkage system. During the movement of the ring 38, by setting a limit frame 37, the movement trajectory of the ring 38 can be limited, further enhancing the stability of the system, avoiding radial deviation or jamming of the ring 38 during movement, ensuring the matching accuracy between components, effectively reducing mechanical wear, and extending the service life of the equipment.

[0035] Furthermore, if Figure 5 and Figure 6 As shown: an elastic joint 44 is fixed to the side of the folding plate 41, and a clamping block 45 is fixed to one end of the elastic joint 44. A third groove 42 is opened in the inner cavity of the telescopic plate 1. By designing the handle 43 into an ergonomic design, the surface texture is non-slip and wear-resistant, providing the user with a comfortable grip, greatly reducing the difficulty of pulling out the folding plate 41, and significantly improving the convenience of use. At the same time, the setting of the folding plate 41 breaks through the original height limitation of the telescopic plate 1. Its vertical area can be extended by flexible pulling to achieve fine adjustment of the overall height to adapt to different usage scenarios. The clamping block 45 cooperates closely with the third groove 42 to form a stable limiting structure, ensuring that the folding plate 41 remains stable in the unfolded or retracted state to avoid accidental sliding. At the same time, the elastic joint 44 installed on the side of the folding plate 41 can provide elastic fixation for the clamping relationship between the two. While assisting in fixing the folding plate 41, it can effectively absorb the stress generated at the moment of clamping, buffer the impact force between components, reduce wear, extend the service life, and further enhance the reliability and durability of the overall structure.

[0036] Working principle:

[0037] like Figure 1-6 As shown:

[0038] When in use: manually push the fixing rod 11 downward along the inner cavity of the fourth groove 12, thereby driving the sliding rod 34 to move downward along the inner cavity of the first groove 35, and then prompting the descending sleeve 33 to drive the ascending sleeve 32 to move clockwise. When the ascending sleeve 32 moves clockwise, it can drive the second groove 36 and the driving connecting rod 22 to move upward along the inner cavity of the limiting frame 37 through the collar 38. By cooperating with the driving connecting rod 22 and the driven connecting rod 24, the telescopic plate 1 can be prompted to move to the side away from the protective shell 31. When the telescopic plate 1 moves to a certain position, the folding plate 41 is manually pulled to prompt the locking The bottom of the block 45 contacts the inner wall of the third groove 42, which can cause the elastic joint 44 to be compressed. When the clamping block 45 moves to a certain position, the elastic joint 44 releases the stress, thereby providing reverse stress for the clamping block 45, thereby causing the clamping block 45 to clamp with the third groove 42, thereby achieving the effect of fully expanding the telescopic plate 1, improving the overall adaptability of the telescopic plate 1, effectively improving the expansion efficiency, and facilitating the support of the equipment. Similarly, after completing the support, by pulling up the handle set at the top of the fixed rod 11, the telescopic plate 1 can be reset, and the folding plate 41 can be pushed upward, thereby causing the telescopic plate 1 to fold and shrink.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
