Description

Technical Field

[0001] This utility model relates to the field of mechanical connection device technology, and in particular to a universal joint device with one-button control. Background Technology

[0002] In the field of mechanical adjustment, universal joints are widely used in scenarios requiring multi-angle positioning, such as camera pan-tilt heads, industrial clamps, and medical equipment. Traditional universal joints typically use a threaded locking method: rotating a threaded sleeve pushes a clamping block to press the ball head, requiring repeated rotation during adjustment, which is inefficient and makes rapid fine-tuning difficult. Existing technology has significant drawbacks: it is difficult and complex to operate, requiring both hands or multiple steps, and cannot meet the needs of frequent adjustments; it also lacks reliability, as wear of mechanical parts can easily lead to play, resulting in poor stability. Summary of the Invention

The button body, transmission component, reset component, and lever component are respectively movably disposed on the connecting arm. One end of the button body is connected to the transmission component. The transmission component is used to drive the lever component to open and act on the top block. The lever component is used to drive the top block to release the universal ball joint. The reset component is used to drive the button body and the transmission component to reset.

[0006] The transmission component includes a pull plate, a transmission slide plate, a transmission slide block, and a guide fixing seat. The button body is rotatably connected to the connecting support arm. One end of the button body is connected to the upper end of the pull plate. One end of the transmission slide plate is connected to the pull plate. The other end of the transmission slide plate is connected to the upper end of the transmission slide block. The guide fixing seat is fixedly installed inside the connecting support arm. The lower end of the transmission slide block is slidably connected to the guide fixing seat.

[0009] The reset component includes a second spring, which is located between the pull plate and the connecting arm, with its two ends connected to the pull plate and the connecting arm, respectively.

[0010] The lever component includes two lever arms facing each other. One end of each lever arm is inclinedly provided with a release guide. The transmission slide is located between one end of the two lever arms. The distance between the release guides of the two lever arms gradually decreases along one end of the lever arm. The other end of each lever arm is rotatably connected to the front end of the connecting arm. Grooves are provided on both sides of the top block. The front end of the other end of the lever arm extends into the groove.

[0011] The clamping assembly includes a pressure block and an elastic element. The elastic element is located between the pressure block and the top block, and its two ends are respectively connected to the pressure block and the top block. The pressure block is installed inside the connecting support arm.

[0012] The one-button controlled universal head device further includes a resistance adjustment assembly, which includes a connecting bracket, a resistance adjustment screw, a transmission bevel gear, a drive bevel gear, and a resistance adjustment element. The connecting bracket is installed inside the connecting arm, and the resistance adjustment element is rotatably mounted on the connecting arm and the connecting bracket.

When the angle of the universal ball joint needs to be adjusted, the top block needs to clamp the universal ball joint. At this time, the operator presses the button body, and the force is transmitted to the lever component through the transmission component. The change in the lever shape causes the top block to slide backward, releasing the clamping force on the universal ball joint. At this time, the direction of the universal ball joint can be freely adjusted. After the position of the universal ball joint is adjusted, the button body is released, and the reset component drives the transmission component and the button body back to their original positions.

This invention has a novel structure, achieving locking / unlocking with one button, replacing the traditional multi-step operation, solving the problem of difficult traditional operation, and improving adjustment efficiency. This invention achieves rapid control of the universal ball joint through mechanical linkage, and is especially suitable for scenarios that require frequent angle adjustments.

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0025] A one-button controlled universal head device, such as Figures 1 to 4 As shown, it includes a connecting arm 100, a top block 1, a universal ball joint 2 movably disposed at the front end of the connecting arm 100, a one-button control assembly 200 mounted on the connecting arm 100, and a clamping assembly 300 mounted inside the connecting arm 100. The top block 1 is slidably disposed at the front end of the connecting arm 100, and the front end of the top block 1 is used to abut against the universal ball joint 2. The clamping assembly 300 is used to push the top block 1 to abut against the universal ball joint 2. The one-button control assembly 200 includes a button body 3 and a transmission component 40. 0. Reset component and lever component 500: The button body 3, transmission component 400, reset component and lever component 500 are respectively movably disposed on the connecting support arm 100. One end of the button body 3 is connected to the transmission component 400. The transmission component 400 is used to drive the lever component 500 to open and act on the top block 1. The lever component 500 is used to drive the top block 1 to release the universal ball head 2. The reset component is used to drive the button body 3 and the transmission component 400 to reset.

[0026] Specifically, in the initial state (when the button body 3 is not pressed), the clamping component 300 continuously pushes the top block 1, keeping the front end of the top block 1 in close contact with the universal ball head 2, and fixing the angle of the universal ball head 2 through friction. When it is necessary to adjust the angle of the universal ball head 2, that is, the top block 1 needs to clamp the universal ball head 2, at which time the operator presses the button body 3, and the force is transmitted to the lever component 500 through the transmission component 400. The change in the lever shape causes the top block 1 to slide backward, releasing the clamping force on the universal ball head 2. At this time, the direction of the universal ball head 2 can be freely adjusted. After the position of the universal ball head 2 is adjusted, the button body 3 is released, the reset component drives the transmission component 400 and the button body 3 to return to their original positions, the lever component 500 no longer acts on the top block 1, and the clamping component 300 pushes the top block 1 again to lock the universal ball head 2. It has good stability, is not easy to loosen, and has a reliable structure. This utility model features a novel structure, enabling one-button locking / unlocking, replacing traditional multi-step operations, solving the problem of difficult traditional operations, and improving adjustment efficiency. This utility model achieves rapid control of the universal ball head 2 through mechanical linkage, and is especially suitable for scenarios that require frequent angle adjustments.

[0027] In this embodiment, the clamping assembly 300 includes a pressure block 14 and an elastic element 15. The elastic element 15 is located between the pressure block 14 and the top block 1, and its two ends are respectively connected to the pressure block 14 and the top block 1. The pressure block 14 is installed inside the connecting arm 100. Specifically, the elastic element 15 can be a spring. With the arrangement of the pressure block 14 and the elastic element 15, the force pushing the top block 1 can be maintained, so that the top block 1 remains clamped against the universal ball joint 2.

[0028] In this embodiment, the transmission component 400 includes a pull plate 4, a transmission slide plate 5, a transmission slide block 6, and a guide fixing seat 7. The button body 3 is rotatably connected to the connecting support arm 100. One end of the button body 3 is connected to the upper end of the pull plate 4, and one end of the transmission slide plate 5 is connected to the pull plate 4. Preferably, one end of the transmission slide plate 5 is hinged to the pull plate 4, and the other end of the transmission slide plate 5 is connected to the upper end of the transmission slide block 6. The guide fixing seat 7 is fixedly installed in the connecting support arm 100. The lower end of the transmission slide block 6 is slidably connected to the guide fixing seat 7, and both sides of the transmission slide block 6 are slidably connected to the lever component 500. The guide fixing seat 7 is provided with a guide groove, and the lower end of the transmission slide block 6 is slidably disposed in the guide groove.

[0029] The lever component 500 includes two lever arms 11 arranged opposite each other. One end of each lever arm 11 is inclinedly provided with a release guide 12. The transmission slide 6 is located between one end of the two lever arms 11. The distance between the release guides 12 of the two lever arms 11 gradually decreases along one end of the lever arm 11. The other end of the lever arm 11 is rotatably connected to the front end of the connecting arm 100. The top block 1 has grooves 13 on both sides. The front end of the other end of the lever arm 11 extends into the groove 13.

[0030] Specifically, under the above settings, when the operator needs to adjust the angle of the universal ball head 2, the universal ball head 2 needs to be unlocked, that is, the top block 1 needs to be released from its contact with the universal ball head 2. At this time, the operator presses the button body 3, causing one end of the button body 3 to flip and lift up, driving the pull plate 4 to move backward, which in turn drives the transmission slide plate 5 to move backward. The transmission slide plate 5 drives the transmission slide block 6 to move backward, which in turn pushes the release guide part 12 at one end of the lever arm 11, so that the front end of the other end of the lever arm 11 extends into the groove 13 and drives the top block 1 to move backward slightly, so that the elastic element 15 is slightly compressed. At this time, the friction between the top block 1 and the universal ball head 2 is reduced, and the universal ball head 2 is unlocked, making it convenient to adjust the direction of the universal ball head 2. When the position of the universal ball head 2 needs to be locked after adjustment, the button body 3 is released. Under the action of the reset component, the button body 3, the transmission slide plate 5 and the transmission slide block 6 are driven to reset, realizing one-button operation and quick reset.

[0031] Furthermore, abutment pulleys 8 are rotatably provided on both sides of the transmission slide 6. Specifically, the abutment pulleys 8 slide against the lever arm 11, reducing wear between the two sides of the transmission slide 6 and the lever arm 11, which helps to improve service life and ensures the smoothness and stability of the sliding between the transmission slide 6 and the lever arm 11.

[0032] In this embodiment, the reset component includes a first spring 9, located between the transmission slide 6 and the guide fixing seat 7, with both ends of the first spring 9 connected to the transmission slide 6 and the guide fixing seat 7 respectively. The reset component also includes a second spring 10, located between the pull plate 4 and the connecting arm 100, with both ends of the second spring 10 connected to the pull plate 4 and the connecting arm 100 respectively. Specifically, under the above configuration, when the button body 3 is not pressed, the elastic force of the first spring 9 and the second spring 10 pushes the button body 3 and the transmission slide 6 back to their initial state. The lever component 500 no longer acts on the top block 1, allowing the top block 1 to remain pressed against the universal ball head 2 under the force of the pressing component 300.

[0033] In this embodiment, the one-button controlled universal head device further includes a resistance adjustment component 600. The resistance adjustment component 600 includes a connecting bracket 16, a resistance adjustment screw 17, a transmission bevel gear 18, a drive bevel gear 19, and a resistance adjustment element 20. The connecting bracket 16 is installed inside the connecting arm 100. The resistance adjustment element 20 is rotatably mounted on the connecting arm 100 and the connecting bracket 16. One end of the resistance adjustment element 20 protrudes into the connecting arm 100 and is fixedly fitted with the drive bevel gear 19. One end of the force adjusting screw 17 slides through the top block 1, and the other end of the resistance adjusting screw 17 is rotatably connected to the connecting bracket 16. The transmission bevel gear 18 is fixedly sleeved on the other end of the resistance adjusting screw 17, and the transmission bevel gear 18 meshes with the drive bevel gear 19 for transmission. The elastic element 15 is movably sleeved on the outer periphery of the resistance adjusting screw 17, and the pressure block 14 is threadedly sleeved on the outer periphery of the resistance adjusting screw 17. The pressure block 14 and the top block 1 respectively slide against the inner wall of the connecting support arm 100. Preferably, the resistance adjusting element 20 is a bolt or a pin.

[0034] The connecting arm 100 has a movable ball cavity 21 at its front end. The universal ball head 2 is movably disposed within the movable ball cavity 21. The front end of the top block 1 extends into the movable ball cavity 21 and abuts against the universal ball head 2. The universal ball head 2 is provided with a threaded connection part 22 for connecting with external equipment. Specifically, the universal ball head 2 is movably and limiter disposed within the movable ball cavity 21 to restrict the range of motion of the universal ball head 2, ensuring that the connected external equipment moves within the limited range.

[0035] Specifically, under the above configuration, rotating the resistance adjusting component 20 drives the drive bevel gear 19 to rotate, which in turn drives the transmission bevel gear 18 to rotate, which in turn drives the resistance adjusting screw 17 to rotate. This causes the pressure block 14 to move back and forth along the resistance adjusting screw 17. When the pressure block 14 moves forward toward the universal ball head 2, the elastic component 15 pushes the top block 1 forward to increase the frictional resistance between the top block 1 and the universal ball head 2. When the resistance adjusting component 20 is rotated in the opposite direction, the pressure block 14 is moved away from the universal ball head 2 to reduce the frictional resistance between the top block 1 and the universal ball head 2. Under the above configuration, the frictional resistance is adjustable, adaptable to external equipment of various weights, and can meet the various angle requirements of external equipment during operation.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
