[0032] As in the background section, traditional universal arms cannot achieve rapid and precise adjustments due to structural issues.

[0033] To solve this technical problem, this utility model provides a damped universal arm bracket, which is used for connecting objects and adjusting the angle of objects.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example

[0035] Please refer to Figure 1 - Figure 6 A damped universal arm support, comprising:

[0036] Component 1 (26) and Component 2 (27) are symmetrically arranged and are used for connecting objects.

[0037] Damping kit 28 is disposed between component one 26 and component two 27, which are movably connected by damping kit 28;

[0038] The limiting component 29 is located at the end of the damping kit 28 and is used to limit the damping kit 28, as well as to limit the rotation of component 1 26 and component 2 27.

[0039] Specifically, component 26 includes a movable arm 15, with a ball head limiting shell 11 fitted on the upper end of the movable arm 15. The lower end of the ball head limiting shell 11 is threadedly connected to the movable arm 15 via a fixing screw 9. A ball cup 7 is placed on the inner bottom of the ball head limiting shell 11. A ball head 5 is ball-jointed to the top of the ball head limiting shell 11. A connector 3 is detachably connected to the top of the ball head 5. A locking screw 1 is provided on the upper end of the connector 3. A push rod 13 is provided inside the movable arm 15. The upper end of the push rod 13 passes through the fixing screw 9 and fits against the bottom of the ball cup 7. The push rod 13 is vertically slidably connected to the fixing screw 9. The lower end of the push rod 13 extends to the inner side of the lower end of the movable arm 15.

[0040] Specifically, component 27 includes movable arm 2 16. The upper end of movable arm 2 16 is fitted with ball head limiting shell 2 10. The lower end of ball head limiting shell 2 10 is threadedly connected to movable arm 2 16 via fixing screw 2 12. A ball cup 2 8 is placed on the inner bottom of ball head limiting shell 2 10. A ball head 2 6 is ball-jointed to the top of ball head limiting shell 2 10. A connector 2 4 is detachably connected to the top of ball head 2 6. A locking screw 2 2 is provided at the upper end of connector 2 4. A push rod 2 14 is provided inside movable arm 2 16. The upper end of push rod 2 14 passes through fixing screw 2 12 and fits against the bottom of ball cup 2 8. Push rod 2 14 and fixing screw 2 12 are vertically slidably connected. The lower end of push rod 2 14 extends to the inner side of the lower end of movable arm 2 16.

[0041] Specifically, the damping kit 28 includes a conical pressure plate 19, an expansion sleeve limiting shell 22, and an expansion sleeve 23. The conical pressure plate 19 is inserted and connected to the bottom of one side of the movable arm 15. The expansion sleeve limiting shell 22 is inserted and connected to the bottom of one side of the movable arm 26. A cover 20 is provided on the outside of the movable arm 15. The cover 20 is fitted on the outside of the conical pressure plate 19. The cover 20 is fixedly connected to the movable arm 15 by screws. A cover 21 is fitted on the outside of the expansion sleeve limiting shell 22. The cover 21 is fixedly connected to the movable arm 26 by screws. The expansion sleeve 23 is placed inside the expansion sleeve limiting shell 22. The end of the conical pressure plate 19 away from the movable arm 15 extends into the interior of the expansion sleeve limiting shell 22. The end of the conical pressure plate 19 located on the inside of the expansion sleeve limiting shell 22 is in contact with the inside of one end of the expansion sleeve 23.

[0042] Specifically, the limiting assembly 29 includes a beveled nut 17, a beveled slider 18, and a locking wrench 24. One end of the beveled nut 17 extends into the inner side of the lower end of the movable arm 15, and sequentially passes through the conical pressure plate 19, the cover 20, the expansion sleeve 23, and the expansion sleeve limiting shell 22 to the inner side of the lower end of the movable arm 26. The end of the beveled nut 17 located inside the lower end of the movable arm 15 is beveled. The lower end of the push rod 13 is in contact with the beveled end of the beveled nut 17. The beveled slider 18 is placed inside the lower end of the movable arm 26. The end of the beveled slider 18 near the beveled nut 17 is beveled. The lower end of the push rod 14 is in contact with the beveled end of the beveled slider 18. One end of the locking wrench 24 passes through the beveled slider 18 and extends into the interior of the beveled nut 17. The locking wrench 24 is threadedly connected to the beveled nut 17. Furthermore, a decorative cover 25 is threadedly connected to the outer side of the locking wrench 24.

[0043] With the above structural design, the conical pressure plate 19 is placed into the movable arm 15 and pressed down by the cover 20. The cover 21, the expansion sleeve limiting shell 22, and the movable arm 16 are installed in the same way. Then, the expansion sleeve 23 is placed into the expansion sleeve limiting shell 22 and the conical pressure plate 19 is connected to it. The inclined nut 17 is passed through any of the previously installed components, and the other component is fitted with the inclined slider 18. Then, the locking wrench 24 is connected to the inclined nut 17 through threads. At this time, components 1 26 and 2 27 are fixed as an integral component with a rotatable shaft in the middle. The ball head 5 is passed through the ball head limiting shell 11 and then inserted into the ball cup 7. At this time, the push rod 13 needs to be inserted into the previously installed movable arm 15, and the ball head 5, ball cup 7, and ball head limiting shell 11 are connected to the previously installed movable arm 15 with the fixing screw 9. The installation method on the other side is the same. Finally, pass the locking screw 1 through the connector 3 to connect the two, and then connect the connector 3 and the ball head 5 together with screws. The installation method on the other side is the same.

[0044] When the locking wrench 24 and the bevel nut 17 are not tightened, the bevel nut 17 and the slider 18 cannot apply pressure to the push rod 13 and the push rod 24. Furthermore, the tension between the locking wrench 24 and the bevel nut 17 is insufficient to make sufficient contact between the intermediate rotating shaft. Therefore, at this time, the spherical surfaces of ball head 15 and ball head 26, the conical pressure plate 19, the expansion sleeve limiting shell 22, and the rotating shaft of the expansion sleeve 23 are all in an active state. In this state, the user can adjust the angles of component 1 26 and component 2 27.

[0045] During operation, simply tightening the locking wrench 24 will shorten the distance between the inclined nut 17 and the inclined slider 18 by pulling the inclined nut 17 tight. Since the inclined nut 17 and the inclined slider 18 have connected inclined surfaces at the same angle as the push rod 13 and push rod 24, when the inclined nut 17 and the inclined slider 18 are subjected to the locking pressure of the locking wrench 24, the inclined surfaces will guide a part of the force upward through the push rod 13 and push rod 24. At this time, the ball cups 7 and 8 connected to the push rod 13 and push rod 24 will be pushed towards the ball head 5 and ball head 6 by the upward guiding force, and the overall movement will stop under the restriction of the ball head 20 and ball head 11.

[0046] Simultaneously, as the distance between the locking wrench 24 and the beveled nut 17 decreases, the conical pressure plate 19, the expansion sleeve limiting shell 22, and the expansion sleeve 23 are also compressed. Since the expansion sleeve 23 has a beveled taper and is an elastic part with an expansion design, it will expand outwards under the compression of the conical pressure plate 19 with the same angle. At this time, the expansion range is limited within the expansion sleeve limiting shell 22. When the locking wrench 24 is continuously pressed, the ball head 5 and the ball head 6 will be locked by the advancement of the ball cup 7 and the ball cup 8 and the restriction of the ball head limiting shell 10 and the ball head limiting shell 11. Similarly, the conical pressure plate 19 will also open the expansion sleeve 23 and lock the expansion sleeve limiting shell 22 under the continuous compression force.

[0047] Through the above structural design, the invention utilizes the intermediate expansion sleeve 23 as an elastic expansion connector. Figure 6 As shown, the tightening force provided by the expansion sleeve 23 varies depending on the magnitude of the force applied to the locking wrench 24. In the extreme test, after applying a pressure of about 10 kg to the locking wrench 24, the middle part can withstand a rotational torque of 1.5 Nm, and the ball joints at both ends can withstand a maximum load of 8 kg under the shortest lever arm and a minimum load of 5 kg under the longest lever arm, which is the maximum tightening force. When the locking wrench 24 is gradually loosened, due to the contraction of the elastic expansion connector and the decrease in the upward guiding force of the push rod 13 and push rod 24, the pivot and ball joint will become in a state with frictional damping. When carrying some lightweight devices, the device can be suspended at any angle, and the angle and position can be adjusted in real time without having to be fully unlocked for adjustment like a traditional universal arm.

[0048] Through the above structural design, the present invention comprises ball head 5 and ball head 6 as shown. Figure 3 The design features a replaceable slot structure. Ball head 5 and ball head 6 have pre-drilled side mounting screw holes, allowing for easy replacement of the connected accessory connectors by removing the screws. This ensures compatibility with different sizes or to achieve different functions. Furthermore, the side-machined mounting screw holes provide greater stability than traditional threaded and glued connectors. Example

[0049] The damping universal arm bracket provided in Example 1 has been further optimized, specifically, as follows: Figure 6 The expansion sleeve 23 shown is a hollow cylinder, and expansion grooves are alternately opened at both ends of the expansion sleeve 23. The inner side of the end of the expansion sleeve 23 near the conical pressure plate 19 is set as a conical surface, and the conical surface is in contact with the surface of the conical pressure plate 19.

[0050] Through the above structural design, the tapered end of the expansion sleeve 23 is squeezed by the tapered pressure plate 19, causing the end of the expansion sleeve 23 to expand and begin to expand. By increasing the friction between the tapered pressure plate 19 and the expansion sleeve 23, and after the expansion sleeve 23 expands, it contacts the inner wall of the expansion sleeve limiting shell 22, thereby achieving a damping effect. Example

[0051] The only difference between this embodiment and the above embodiment 2 is the structure of the expansion sleeve 23. Specifically, the expansion sleeve 23 in this embodiment is a hollow cylinder. A split through groove is provided on one side of the expansion sleeve 23 along the axial direction. A connecting rod 30 is inserted into the split through groove. The end of the connecting rod 30 away from the expansion sleeve 23 is connected to the conical pressure plate 19.

[0052] Through the above structural design, the expansion sleeve 23 can also be expanded by pressing the end of the expansion sleeve 23 with the conical pressure plate 19. At the same time, the conical pressure plate 19 can be quickly connected to the expansion sleeve 23 through the connecting rod 30. At this time, the friction force will act on both component one 26 and component two 27.
