Description

Technical Field

[0001] This utility model relates to the field of support equipment, specifically to a multifunctional support. Background Technology

[0002] With the development of technology, various stand products are widely used in daily life and work, such as mobile phone stands, tablet stands, and reading stands. These stand products usually need to have angle adjustment functions to meet the user's needs in different scenarios.

[0003] Currently, existing bracket products still have some problems in the design of angle adjustment mechanisms. Most bracket products use a damping structure composed of screws and nuts to fix the angle. This structure has obvious problems with poor user experience: when the nut is tightened too much, it is difficult for users to adjust the bracket angle and a lot of force is required to complete the adjustment; when the nut is loose, the bracket cannot effectively support heavy objects and is prone to tipping over or angle deviation, resulting in a very poor user experience.

[0004] Some stand products on the market also use a rotating structure to achieve angle adjustment, for example: See patent publication number CN114754062A for a rotating mechanism, which includes a rotating shaft, a rotating component, a limiting component, a locking component, and an elastic component. The rotating component can rotate relative to the rotating shaft to a specific angle and then remain suspended, thus realizing the angle adjustment function of the bracket. See CN105626676A for a locking mechanism that includes a first mating member, a second mating member, a clamping arm, an elastic member, and an unlocking member. The clamping arm switches between open and closed states under the action of the unlocking member. In the closed state, the second mating member is braked relative to the first mating member, and in the open state, the second mating member can rotate relative to the first mating member under the action of an external force.

[0005] See CN214284188U for a lockable rotary joint, which includes a first rotating member, a second rotating member, a joint locking member, a first elastic member, and a secondary locking mechanism. The locking and unlocking of the rotary joint is achieved by switching the joint locking member in different working positions.

[0006] However, the aforementioned rotating structure is complex and inconvenient to operate. Furthermore, it is prone to wear and loosening after frequent adjustments and use, which affects the service life and stability of the support.

[0007] Therefore, there is an urgent need for a multifunctional bracket that is simple in structure, easy to operate, and securely locked, which can provide stable and reliable support in different usage scenarios, while also having a convenient angle adjustment mechanism to improve the user experience. Summary of the Invention

[0008] The purpose of this invention is to provide a multifunctional bracket that solves the problems of inconvenient angle adjustment and limited application scenarios of traditional brackets.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional support includes a first support and a second support, which are rotatably connected by a rotating assembly. The rotating assembly includes a first rotating member, a second rotating member, a connecting member, and an elastic member.

The first rotating member is inserted into the second rotating member, and the first and second rotating members can rotate relative to each other around their center line and move relative to each other along the extension direction of their center line. One end of the connecting member passes through the second rotating member and connects to the first rotating member and / or the first support. The elastic member is sleeved on the connecting member and abuts against the other end of the second rotating member and the connecting member. The bracket has a locked state and an unlocked state. When the first tooth of the first rotating member and the second tooth of the second rotating member are engaged, the bracket is in the locked state, and the first bracket and the second bracket are relatively fixed. When the first bracket and the second bracket move relative to each other, causing the first tooth of the first rotating member and the second tooth of the second rotating member to disengage, the bracket is in the unlocked state, and the first bracket and the second bracket can rotate relative to each other. The elastic member provides a restoring force to the first tooth of the first rotating member and the second tooth of the second rotating member in the event of engagement.

[0010] Preferably, in the above technical solution, the bracket further includes a third bracket, and the first bracket and the third bracket are rotatably connected by the rotating component.

In use, the mutual rotation between the first support 10 and the second support 11, and between the first support 10 and the third support 12 can be flexibly selected, providing high flexibility in use.

[0031] like Figure 4 , 5 As shown: The rotating assembly 2 mainly includes a first rotating component 20, a second rotating component 21, a connecting component 22, and an elastic component 23.

[0032] In the figure, the first rotating member 20 is cylindrical, and a first tooth 200 is provided on the outer periphery of one end; the second rotating member 21 is hollow inside, and the hollow part matches the shape of the first rotating member 20. A second tooth 210 is provided inside the hollow part. The first rotating member 20 is fixedly connected to the upper and lower ends of the side bracket 100 of the first bracket 10. The second rotating member 21 is fixedly connected to the connecting part 110 of the second bracket 11 and the connecting part 120 of the third bracket 12. The connection method can be a fixed connection method such as bolts and nuts 24, welding, or bonding. The first rotating member 20 is inserted into the second rotating member 21, and the first rotating member 20 and the second rotating member 21 can rotate relative to each other around their center line and can move relative to each other along the extension direction of their center line.

[0035] The aforementioned rotating assembly 2 can enable the bracket to be in a locked state and an unlocked state. When the first tooth 200 of the first rotating member 20 and the second tooth 210 of the second rotating member 21 are engaged, the bracket is in the locked state. Figure 6 As shown, the first bracket 10 and the second bracket 11, and the first bracket 10 and the third bracket 12 are relatively fixed; when the first bracket 10 and the second bracket 11, and the first bracket 10 and the third bracket 12 move relative to each other, causing the first tooth 200 of the first rotating member 20 and the second tooth 210 of the second rotating member 21 to disengage, the bracket is in an unlocked state, as shown. Figure 7 As shown, the first bracket 10 and the second bracket 11, and the first bracket 10 and the third bracket 12 can rotate relative to each other; the elastic member 23 provides a restoring force to the first tooth 200 of the first rotating member 20 and the second tooth 210 of the second rotating member 21.

[0036] The specific operating steps are as follows: Control the first bracket 10 and the second bracket 11 (or the third bracket 12), and apply force left and right along the center line of the rotating assembly 2. At this time, the first tooth 200 of the first rotating member 20 and the second tooth 210 of the second rotating member 21 disengage, and the elastic member 23 located between the second rotating member 21 and the other end of the connecting member 22 is compressed. The rotating assembly 2 connecting the first bracket 10 and the second bracket 11 (or the third bracket 12) is unlocked. Then, rotate the first bracket 10 and the second bracket 11 (or the third bracket 12) to adjust the required angle. Release the first bracket 10 and the second bracket 11 (or the third bracket 12), and the elastic member 23 located between the second rotating member 21 and the other end of the connecting member 22 is released, so that the first tooth 200 of the first rotating member 20 and the second tooth 210 of the second rotating member 21 mesh. At this time, the rotating assembly 2 connecting the first bracket 10 and the second bracket 11 (or the third bracket 12) is locked, and the bracket remains in a stable state.

[0037] Example 2: like Figure 1 , 2 As shown in Figure 3: This embodiment is basically the same as the first embodiment. Further: In this embodiment, one or more blocking members 121 are provided on the third support 12. In the figure, there is a pair of blocking members 121, that is, two.

The headrest 3 can be placed between the third bracket 12 and the blocking member 121 to form a support area. The headrest 3 can be placed and removed, making it easy to clean and improving the hygiene of the product.

[0039] In a preferred embodiment of this example: the middle part of the third support 12 and the middle part of the headrest 3 are provided with notches 122 and 30, which can be used for facial ventilation and improve the comfort of use.

[0040] Example 4: like Figure 9 As shown: This embodiment is basically the same as Embodiment 2, except that in this embodiment, the bracket is equipped with a functional component, which is the reading rack 4. Specifically: like Figure 10 As shown: The reading holder 4 includes a connecting part 40 and a clamping member 41. Wherein: The connecting part 40 is used to connect to the third bracket 12. In this embodiment, the connecting part 40 is provided with a bayonet 400. The bayonet 400 of the connecting part 40 can be locked onto the blocking member 121 of the third bracket 12, so that the reading rack 4 is connected to the third bracket 12.

[0041] One end of the abutment 41 is connected to the connecting part 40. When the reading rack 4 is connected to the third support 12, the other end of the abutment 41 extends toward the third support 12.
