Description

Technical Field

[0001] This invention relates to the field of operating device technology, and more particularly to operating devices with control mechanisms and their applications. Background Technology

[0002] In existing technologies, locking or unlocking can be controlled by operating a device, such as locking or unlocking the support legs in a tripod. However, most existing technologies rely on direct rotation for horizontal control, followed by meshing control. For example, the quick-lock operating mechanism disclosed in CN 217464007 U has a complex structure, requiring the addition of various small structures such as ball bearings, resulting in high costs and complex internal transmission. Furthermore, the rotation of the ball bearings can be affected after long-term use or water seepage. Summary of the Invention

[0003] The purpose of this invention is to provide an operating device with a control mechanism and its application, which has the advantages of simple structure and easy operation.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0005] An operating device with a control mechanism, including, A fixed seat forming a through cavity, An operating mechanism that is rotatably disposed in the radial direction of the through cavity, and a cam that is linked to the operating mechanism; A first transmission component is slidably disposed in the through cavity and linked with the cam, and the first transmission component is connected to a control mechanism through a second transmission component; The operating mechanism drives the first transmission component to move, causing the second transmission component to rotate in a spiral motion, which in turn drives the control mechanism to form a first control state and a second control state.

[0006] Furthermore, the first transmission member forms a sliding frame arranged along the same center line as the through cavity, and the second transmission member moves spirally within the sliding frame.

[0007] Furthermore, the sliding frame has a radially formed limiting groove, and the cam is assembled in the limiting groove.

[0008] Furthermore, the sliding frame is a tubular structure, and the tubular structure is axially hollowed out to form the limiting groove, and the second transmission component rotates into or out of the tubular structure.

[0009] Furthermore, the cam forms a horizontal limiting mechanism on the fixed seat, and the first transmission member is located within the limiting mechanism.

[0010] Furthermore, during the movement of the cam, the first transmission member, and the second transmission member, a first curved surface trajectory, a straight line trajectory, and a second curved surface trajectory are formed, respectively.

[0011] Furthermore, the first surface trajectory is a spiral curve formed by rotating around the X-axis, the straight line trajectory is a straight line rising and falling along the Y-axis, and the second surface trajectory is a spiral curve formed by rotating around the Y-axis.

[0012] Furthermore, the second transmission component includes a base and an extension tube above the base, the extension tube protruding axially to form several spiral structures.

[0013] Furthermore, the fixed seat is partially recessed to form a limiting step for overlapping the base.

[0014] Furthermore, it also includes a transmission component connected to the control mechanism at the bottom, wherein the transmission component is partially fixedly connected to the extension tube.

[0015] Furthermore, the operating mechanism and the cam are assembled on the fixed base via a linkage pin, and the swing arm of the operating mechanism drives the cam to reciprocate.

[0016] Furthermore, the control mechanism extends partially into the through cavity and cooperates with the second transmission component within the through cavity.

[0017] Furthermore, the control mechanism is a transmission rod, and in the first control state and the second control state, the rotation direction of the transmission rod is opposite.

[0018] Furthermore, the transmission rod is connected to a locking assembly, and in the first control state and the second control state, one is the unlocked state and the other is the locked state.

[0019] On the other hand, the application of operating devices with control mechanisms specifically includes the application in the extension and retraction control of telescopic tubes in tripods, monopods, selfie sticks, walking sticks, trekking poles, or tarp poles, or the application in the control of the tripod's center column. The beneficial effects of this invention are as follows: In this invention, by adding a cam, rotation with an eccentric tendency is achieved, and then the rotation is linked to various transmission components, thereby achieving control over different control states.

[0020] In this invention, each transmission component has a simple structure and is directly controlled by sliding with the fixed base and relative rotation, without the need for additional structures, resulting in low cost and easy operation of the control state. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0023] Example 1 See attached document Figure 1-6 As shown, the operating device with control mechanism in this embodiment specifically includes a fixed base 1 forming a through cavity, an operating mechanism 2 rotatably disposed in the radial direction of the through cavity, and a cam 3 linked with the operating mechanism 2. In this embodiment, the operating mechanism 2 is disposed in the radial direction of the through cavity, that is, in the length direction, so as to facilitate rotation along the through cavity and direct operation by the user. The operating mechanism 2 is linked with the cam 3. At this time, the cam 3 not only has an eccentric motion tendency, but can also convert the rotational motion into linear motion, thereby providing a basis for subsequent linear motion in the fixed base. In this embodiment, the first transmission component 4 is slidably disposed within the through cavity and simultaneously linked with the cam 3. Under the action of the cam, the first transmission component 4 can slide linearly within the through cavity. Subsequently, the first transmission component 4 is connected to the control mechanism 6 via the second transmission component 5. Thus, the first transmission component 4, in its movement, drives the second transmission component 5 and the control mechanism 6, achieving the final linkage. Specifically, the operating mechanism 2 drives the first transmission component 4 to move, causing the second transmission component 5 to rotate helically. This causes the second transmission component 5 to drive the control mechanism 6 to form a first control state and a second control state. In this embodiment, the control mechanism 6 is mainly controlled by the helical rotation of the second transmission component 5. The helical rotation specifically includes an arc rotation of less than one turn or a multi-turn threaded rotation, etc. The arc rotation can be an eccentric rotation or a rotation centered on the second transmission component 5. Therefore, the assembly of the second transmission component 5 and the first transmission component 4 can be done in various ways. In this embodiment, the motion mode is changed mainly by the action of the cam, which simplifies the subsequent structure settings and adjustments, making the structure simpler, reducing costs, and extending service life.

[0024] Example 2 This embodiment mainly introduces the first transmission component 4.

[0025] To reduce costs, in this embodiment, the first transmission member 4 forms a sliding frame with the same center line as the through cavity, thereby forming a certain limiting space. Then, the second transmission member 5 moves spirally along the sliding frame. With the same center line, the second transmission member 5 tends to rotate synchronously with the fixed base 1, thus forming a trend of overall linkage.

[0026] During assembly, since the sliding frame is a frame structure design, it can make full use of the structural features on both sides, such as directly hollowing out both sides or circumferentially hollowing out, and then forming a radial limiting groove 41. The cam 3 is set in the limiting groove 41 in the vertical direction, so that the cam 3 can only move laterally during rotation and has a certain limit in the vertical direction. The limiting groove is also the assembly groove of the cam, which achieves multiple benefits.

[0027] Specifically, the sliding frame is a tubular structure, and the tubular structure is axially hollowed out to form the limiting groove 41, which facilitates the formation of the limiting groove 41. The second transmission member 5 enters or exits the tubular structure by rotating. When the second transmission member 5 enters or exits, it will drive the sliding frame to move vertically up and down along the fixed seat.

[0028] In this embodiment, two cams 3 can be set, and the cams 3 are located on both sides of the first transmission member 4. They form a horizontal limiting mechanism on the fixed seat 1. The limiting groove in the sliding frame cooperates with the horizontal limiting mechanism. Thus, the first transmission member 4 is limited in the horizontal direction by the two cams 3, so that it can only slide in the vertical direction (i.e., axial direction).

[0029] Example 3 This embodiment mainly describes the relative working process between the cam and the two transmission components.

[0030] In this embodiment, the first curved surface trajectory is a spiral curve formed by rotating around the X-axis, the straight line trajectory is a straight line rising and falling along the Y-axis, and the second curved surface trajectory is a spiral curve formed by rotating around the Y-axis. The first curved surface trajectory is the motion trajectory of the cam, which can be eccentrically set according to requirements, while the straight line trajectory moves within the limiting length formed by the fixed seat 1. The second curved surface trajectory can have various structures, such as partial threads or multi-turn threads.

[0031] In this embodiment, the second transmission component 5 includes a base 51 and an extension tube 52 above the base 51. The extension tube 52 protrudes axially to form several spiral structures. For example, the extension tube 52 protrudes to form an eccentric trajectory, thereby causing the first transmission component 4 to rotate eccentrically, or directly forms a partial arc shape to rotate the center, or is provided with a multi-turn spiral structure to rotate multiple times.

[0032] In this embodiment, in order to prevent the second transmission component 5 from slipping off the fixed seat 1, the fixed seat 1 is partially recessed to form a limiting step 11 for the base 51 to overlap. At this time, the two are assembled in the fixed seat 1 by overlapping.

[0033] To coordinate with the control mechanism, a transmission component 7 is also included, which is connected to the control mechanism 6 at its bottom. The transmission component 7 is partially fixedly connected to the extension tube 52. In this embodiment, the transmission component 7 may be a rotating rod, etc., which is then rotatably connected to the control mechanism 6, causing the control mechanism 6 to rotate forward or backward to complete control states such as unlocking or locking.

[0034] Example 4 This embodiment focuses on describing some local details.

[0035] In this embodiment, the operating mechanism 2 and the cam 3 are assembled on the fixed base 1 via a linkage pin 8. The swing arm 21 of the operating mechanism 2 drives the cam 3 to reciprocate. The operating mechanism 2 is provided with an operating part. The user controls the operating part to rotate along the fixed base 1 with the linkage pin 8 as the rotation point, thereby controlling the rotation direction of the cam 3 and driving the control transmission component to achieve the control of the final control mechanism.

[0036] In this embodiment, in order to ensure the linkage of the control mechanism, the control mechanism 6 is partially inserted into the through cavity and rotates with the second transmission component 5 in the through cavity. For example, the end of the control mechanism 6 is inserted into the second transmission component 5 and fixed thereto, for example, by using screws or the like for concentric fixed connection.

[0037] Specifically, the control mechanism 6 is a transmission rod. In the first control state and the second control state, the rotation direction of the transmission rod is opposite. At this time, the control state can be adjusted by simply rotating the rod.

[0038] Furthermore, the transmission rod is connected to a locking assembly. In the first control state and the second control state, one is the unlocked state and the other is the locked state. Here, the locking assembly specifically uses a conventional locking mechanism, and the transmission rod acts as the driving force of the control mechanism. By adjusting the driving direction, the unlocked or locked state can be adjusted and changed.

[0039] Example 5 In this embodiment, the application is described in conjunction with the example.

[0040] In this embodiment, the aforementioned operating device with a control mechanism is specifically used in telescopic tube control or tripod center axis control. For example, in the telescopic tube locking or unlocking, a drive mechanism is needed to drive the locking or unlocking, or in the tripod center axis control, the aforementioned operating device can be directly assembled at the center axis fixing seat.

[0041] In this embodiment, the operating mechanism 2 is formed by a wrench, and the fixed seat 1 is formed by a tubular structure. The fixed seat 1 has holes on both sides at a set height. The cam 3 then passes through these holes and completes the assembly here by bushings and positioning beads.

[0042] The first transmission component 4, which is formed by a sliding frame, has a sliding groove in one of its components and a slider in the other, which completes the axial sliding assembly with the fixed base 1.

[0043] The second transmission component 5 is a structure that is set on the same center line as the fixed base 1. During assembly, a threaded structure is provided inside the extension tube 52. After the screw is threadedly connected to the extension tube 52 through the threaded structure, it extends into the transmission component 7 and is then threadedly connected to the transmission component 7 to complete the fixed connection between the second transmission component 5 and the transmission component 7.

[0044] A limiting groove 41 is provided at the first transmission component 4. When the first transmission component 4 slides along the fixed seat 1 to the set height, the limiting groove 41 corresponds to the position of the cam 3 and completes the matching. Then, the linkage pin 8 completes the assembly through the assembly hole at the end of the operating mechanism 2, the fixed seat 1, and the cam.

[0045] When the cam is assembled with the fixed seat 1, a positioning hole for the positioning ball to pass through is provided at the bottom of the hole on the side of the fixed seat 1, and a bushing is added to make the entire assembly more secure.

[0046] In this embodiment, the wrench has an inverted U-shaped symmetrical structure and is directly and symmetrically assembled on both sides of the fixed base 1. The limiting step 11 at the bottom of the fixed base 1 allows the second transmission member 5 to be limited, so that it can rotate above the limiting step 11.

[0047] The inner wall of the first transmission member 4, which is formed by the sliding structure, is matched with the thread on the extension tube 52. As the first transmission member 4 moves up and down, the thread here forms a certain rotation direction. Thus, the horizontal sliding of the first transmission member 4 can also be limited to the limit step 11.

[0048] See attached document Figure 7 As shown, this embodiment takes the application in a tripod as an example. For example, a tripod 9 is provided with several telescopic legs 91. Adjacent telescopic legs 91 form an inner tube and an outer tube. A locking mechanism is provided between the inner tube and the outer tube, such as the locking mechanism in the infinite telescopic tube disclosed in CN118482079A. At this time, by controlling the different rotations of the control mechanism 6 and the transmission component 7, the telescopic leg formed by the second telescopic tube in this technology is rotated, thereby driving the drive end and the sliding frame to rotate, completing the locking and unlocking between the two telescopic tubes.

[0049] In this embodiment, the locking component can also be a joint seat that slides along the telescopic leg 91 with a smaller diameter. The transmission rod in the control mechanism 6 extends into the joint seat and is fixedly connected to it. Then the joint seat forms a frame structure. Several expansion blocks are set on the outside of the frame structure. As the transmission rod drives the joint seat to rotate, the expansion blocks interfere with or eliminate interference with the telescopic leg 91 with a larger diameter, thereby achieving locking or unlocking.

[0050] See attached document Figure 8 As shown, this invention is applied to trekking poles. In this case, an operating device with a control mechanism is directly set on the top of the telescopic leg 91 to control the entire telescopic locking process.

[0051] The operating device with a control mechanism in this embodiment, whether used alone or applied, such as in the telescopic control of the telescopic tube in tripods, monopods, selfie sticks, canes, trekking poles, or tarp poles, or in the control of the tripod's center column, operates on the following principle: First, the linkage of the first transmission component 4 within the fixed base 1 is controlled by the operating mechanism 2. At this time, the first transmission component 4 is slidably mounted along the axis inside the fixed base 1, while the second transmission component 5 is rotatably mounted. The first transmission component 4 moves along the axis inside the fixed base 1, and the second transmission component 5 rotates around the axis inside the fixed base 1. This process completes the initial linkage or operational control.

[0052] Secondly, a limiting groove 41 with upper and lower limiting surfaces is provided on the first transmission component 4, and the cam 3 moves within the limiting groove 41 of the first transmission component 4. When the cam 3 rotates, it can drive the first transmission component 4 to move up and down. In the above process, compared with other existing transmissions, the cam 3 is selected for driving, which greatly utilizes the advantages of the cam's rotational motion to linear motion, as well as the eccentricity during rotation.

[0053] In this embodiment, the first transmission component 4 and the second transmission component 5 are screwed together, thereby achieving the effect of driving the second transmission component 5 to rotate forward and backward when the first transmission component 4 moves up and down.

[0054] In this embodiment, the first transmission component 4 is a square frame structure with at least two concave sides and U-shaped structures formed on the sides for assembling the cam 3. Between the two U-shaped structures is a cylindrical structure, and then a thread is formed inside the cylindrical structure to be threadedly connected to the thread on the outside of the extension tube 52.

[0055] See attached document Figure 3-4 As shown, in this embodiment, locking is achieved by the upward movement of the first transmission component 4 during rotation. Figure 3 This is the first control state for locking. Figure 4 The first transmission component 4 is driven to move downwards, forming the second control state of unlocking, and thus forming different states.

[0056] In this embodiment, the wrench is fixedly connected to the cam 3 via a linkage pin 8, and the subsequent transmission rod is fixedly connected to the second transmission component 5 via a transmission component. When the wrench is moved, the cam 3 rotates, thereby causing the transmission rod to rotate in both directions, thus realizing the unlocking and locking functions.

[0057] In this embodiment, a cam is cleverly used as a drive, thereby realizing multiple linkages within the limiting cavity formed by the fixed seat 1. This provides a basic idea for linkages formed by simple structures in a small space. Compared with complex structures such as internal lateral rotation or meshing, this embodiment achieves the effect of simple structure and low cost.
