Description

Technical Field

[0001] This utility model relates to the field of bracket technology for supporting items, and more particularly to a bracket. Background Technology

[0002] In daily work and life, we often need to use stands to support items, such as a mobile phone on a dining table, an umbrella on a camera stand, a flashlight on a bicycle, or a desk lamp on a workbench. Currently, most commonly used stands cannot rotate in any direction, failing to meet the need for rotating supported items. Chinese Patent Publication No. CN201596904 discloses a universal joint stand, which uses a pressure cap on a first connecting rod and a rotating ball on a second connecting rod. The first connecting rod, pressure cap, and rotating ball form a rotating joint, allowing the two connecting rods to rotate 360 ​​degrees. However, this rotating stand has a problem: it cannot achieve a more secure fixation after rotation. When the supported item is heavy, the rotating stand may rotate to the bottom, or external force may also cause the stand to rotate to the bottom. Therefore, how to effectively lock the two rotating connecting rods is a technical problem that urgently needs to be solved. Utility Model Content

[0003] In view of this, the present invention provides a bracket that solves the technical problem that the connecting rods of the existing rotating bracket cannot be locked and fixed.

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0016] like Figures 1 to 3As shown, a bracket includes a first connecting rod 1, a second connecting rod 2, a first fixing clip 3, and a second fixing clip 4. One end of the first connecting rod 1 and the second connecting rod 2 are respectively fixedly connected to the first fixing clip 3 and the second fixing clip 4 via universal joints 5. The universal joint 5 is a common existing technology, consisting of a support rod, a ball head 51, and a sleeve. Specifically, in this design, the support rod is directly fixed to the first fixing clip, the ball head 51 is inside the sleeve, and the other end of the support rod is fixed to the ball head 51, allowing the sleeve to rotate at any angle relative to the ball head 51. In use, the first fixing clip 3 is fixed to a fixed object (such as a table, camera stand, bicycle, etc.), and the second fixing clip 4 is used to fix the desired items (such as umbrellas, mobile phones, etc.). The other ends of the first connecting rod 1 and the second connecting rod 2 are loosely connected to each other, typically using a threaded connection. The bracket also includes a locking component 6 to prevent the universal joint 5 from rotating. The purpose of locking component 6 is to prevent the universal joint 5 from rotating. There are many ways to achieve this. For example, locking component 6 can be a limit pin, which can be directly provided on the sleeve and ball head 51 of the universal joint 5 to prevent the sleeve from rotating relative to the ball head 51. In actual use, after fixing the first fixing clamp 3, adjust the first connecting rod 1 and the second connecting rod 2 to the required angle, then tighten the first connecting rod 1 and the second connecting rod 2, then lock the universal joint of the first connecting rod 1 and the second connecting rod 2, and finally fix the item to be supported on the second fixing clamp 4.

[0017] The above-described embodiments are the more basic implementations of this utility model. The following describes another more preferred embodiment:

[0018] This achieves the goal of simultaneously securing the first connecting rod 1 and the second connecting rod 2 together, while also preventing the universal joint 5 from rotating due to the locking assembly 6. Specifically, each of the first connecting rod 1 and the second connecting rod 2 has a transverse cylindrical groove 7 at its other end. A stud 8 is fixed within the cylindrical groove 7 of the second connecting rod 2. After the stud 8 passes through the cylindrical groove 7 of the first connecting rod 1, the tightness of the first connecting rod 1 and the second connecting rod 2 is controlled by rotating the handle 9. It is easy to understand that the stud 8 has external threads, and the rotating handle 9 has internal threads. Rotating the handle 9 into the stud 8 secures the first connecting rod 1 and the second connecting rod 2. Both the first connecting rod 1 and the second connecting rod 2 have through holes 10 extending axially. Figure 2 and Figure 3As shown, the locking assembly 6 includes a concave pad 61, an inner rod 62, and a cylindrical slider 63. The concave pad 61 fits onto the ball head 51 of the universal joint 5. It is easy to understand that the concave shape of the pad 61 matches the spherical shape of the ball head 51. The cylindrical slider 63 is placed within a cylindrical groove 7. The cylindrical slider 63 has an axial circular hole 64 for the stud 8 to pass through, and an arc-shaped groove 65. The concave pad 61 is fixedly connected to one end of the inner rod 62; here, the concave pad 61 and the inner rod 62 are connected by a thread. The inner rod 62 passes through the through hole 10, and the other end of the inner rod 62 contacts the arc-shaped groove 65 of the cylindrical slider 63.

[0019] During installation, the stud 8 passes through the two cylindrical sliders 63 placed in the cylindrical groove 7. Then, the tightness of the first connecting rod 1 and the second connecting rod 2 is controlled by rotating the handle 9 and screwing it into the stud 8. In this embodiment, refer to... Figure 3 The locking component 6 locks the universal joint 5 on the following principle: After the rotating handle 9 is screwed into the stud 8, the end of the rotating handle 9 contacts the cylindrical slider 63 inside the first connecting rod 1. As the rotating handle is tightened, the end of the rotating handle 9 naturally pushes the cylindrical slider 63 to slide relative to the cylindrical groove 7. The upper end of the inner rod 62, which is in contact with the arc groove 65 of the cylindrical slider 63, gradually moves from the middle to the side as the arc groove 65 shifts. The inner rod 62 is pressed down by the arc groove, so the inner rod 62 passively moves downward along the axial direction of the first connecting rod 1. The concave pad 61 at the lower end of the inner rod 62 naturally adheres tightly to the spherical surface of the ball head 51 of the universal joint 5, thereby controlling the ball head 51 to prevent rotation, thus achieving the purpose of locking the universal joint 5 to prevent rotation. To better match the relative movement of the arc groove 65, the other end of the inner rod 62 is set to be spherical. The cylindrical slider 63 inside the second connecting rod 2 is also pushed and displaced by the cylindrical slider 63 inside the first connecting rod 1. Therefore, the principle by which the inner rod 62 and the concave pad 61 inside the second connecting rod 2 can lock the universal joint 5 is the same as the locking principle of the first connecting rod 1 described above.

[0020] To improve the linkage effect of the cylindrical sliders 63 between the first connecting rod 1 and the second connecting rod 2, a spring 11 can be installed between the cylindrical sliders 63 of the first connecting rod 1 and the second connecting rod 2. To prevent the rotating handle 9 from slipping, an anti-slip washer 12 can be provided on the stud 8 located between the rotating handle 9 and the first connecting rod 1. With the locking component 6, the bracket can lock the universal joint 5 to prevent rotation while fixing the first connecting rod 1 and the second connecting rod 2. In actual use, the first fixing clamp 3 is clamped on a stable object, and the item to be supported and fixed is fixed on the second fixing clamp 4. The bracket can be adjusted to any angle through the universal joint 5 and the rotation between the first connecting rod 1 and the first connecting rod 2. The height is adjusted by controlling the angle between the first connecting rod 1 and the first connecting rod 2. After adjustment, tightening the rotating handle 9 can fix the first connecting rod 1 and the first connecting rod 2 and lock the universal joint 5, making the bracket more secure after orientation. Application scenarios include, but are not limited to: securing umbrellas to photography tripods, securing umbrellas to strollers, securing lamps to workbenches, securing mobile phones to tables, and securing flashlights to bicycles.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
