Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically to a support structure with an adjustable angle. Background Technology

[0002] With the continuous development of technology, electronic devices such as mobile phones and tablets have been widely used in people's daily lives and work. When using these devices to watch videos, make video calls, or perform other operations, a stand is usually needed to support the device for a better visual experience and ease of operation.

[0003] Currently, existing tablet stands have certain shortcomings. For example, the hinges at the joints of the stands typically use hinges with high damping to achieve angle adjustment. To ensure that the stand can provide sufficient support for the tablet after angle adjustment, the damping at the joints is set quite high. While this design meets the support requirements, it brings significant inconvenience to use. Users need to apply considerable force to complete the angle adjustment process, making the entire adjustment extremely strenuous and resulting in a poor user experience.

[0004] Therefore, it is necessary to provide a bracket structure with an adjustable angle to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a support structure with an adjustable angle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotatable and adjustable support structure, comprising:

[0008] A base, wherein a fixed seat is fixedly installed on the rear side of the top of the base, a fixed shaft is fixedly installed on the fixed seat, a first gear is fixedly installed on the outer wall of the fixed shaft, symmetrically distributed support arms are rotatably installed on the outer wall of the fixed shaft, a movable shaft is rotatably installed between the ends of the two support arms, and a second gear is fixedly installed on the outer wall of the movable shaft.

[0009] Symmetrically distributed connecting seats are fixedly installed on the outer wall of the movable shaft. A placement plate is fixedly installed on the top of the connecting seat. A fixing plate is fixedly installed between the two support arms. A limit mechanism is provided on the fixing plate.

[0010] Preferably, the limiting mechanism includes two fixing slots, which are symmetrically distributed at the front and rear ends of the fixing plate. A toothed plate is slidably inserted into each of the two fixing slots, and the two toothed plates are respectively engaged with the first gear and the second gear at corresponding positions. A plurality of springs are fixedly installed between the end of the toothed plate inside the fixing slot and the inner wall of the fixing slot. A through slot corresponding to the position and number of the fixing slots is opened on the top of the fixing plate. A slider is fixedly installed on the top of the toothed plate, and the slider passes through the interior of the through slot and is slidably connected to the through slot.

[0011] Preferably, an operating block is fixedly installed on the top of the slider, and a baffle plate is fixedly installed on the opposite surfaces of the two operating blocks.

[0012] Preferably, the area of ​​the baffle plate is larger than the area of ​​the opening at the top of the channel.

[0013] Preferably, a groove is provided on one side of the base, and a handle is fixedly installed inside the groove.

[0014] Preferably, anti-slip pads are adhered to both sides of the bottom of the base.

[0015] Preferably, the front end of the placement plate is provided with symmetrically distributed folded edges.

[0016] Preferably, the placement plate has symmetrically distributed heat dissipation holes.

[0017] Preferably, the outer surface of the operating block is provided with an anti-slip wrapping layer.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model utilizes a base, fixed seat, fixed shaft, support arm, first gear, placement plate, fixed plate, second gear, toothed plate, movable shaft, connecting seat, operating block, through groove, fixed groove, and spring in combination. An angle adjustment and positioning are achieved through a limiting mechanism. During operation, moving the operating block releases or restores the engagement between the toothed plate and the gear, allowing for flexible adjustment and locking of the rotation angle of the support arm and placement plate, ensuring stable placement plate angle. The same operation allows for quick folding during storage. Compared to traditional damping shaft methods, this limiting mechanism is simple in structure, convenient to operate, and saves time and effort in angle adjustment, greatly improving the product's ease of use.

[0020] 2. This utility model utilizes a baffle plate. During the operation of the operating block to control the position of the toothed plate, the movement of the operating block drives the baffle plate to slide on the corresponding track, thus covering the through slot. This covering effectively prevents dust and impurities from the external environment from entering the fixed slot through the through slot during the use of the bracket, thereby avoiding adverse effects on the operational stability of the mechanical components within the fixed slot and ensuring that the mechanical components can continuously and stably perform their functions.

[0027] Please see Figures 1-4 One embodiment provided by this utility model:

[0028] A rotatable and adjustable support structure, comprising:

[0029] A base 1 has a fixed seat 2 fixedly installed on the rear side of the top of the base 1. A fixed shaft 3 is fixedly installed on the fixed seat 2. A first gear 5 is fixedly installed on the outer wall of the fixed shaft 3. Symmetrically distributed support arms 4 are rotatably installed on the outer wall of the fixed shaft 3. A movable shaft 14 is rotatably installed between the ends of the two support arms 4. A second gear 12 is fixedly installed on the outer wall of the movable shaft 14.

[0030] Symmetrically distributed connecting seats 15 are fixedly installed on the outer wall of the movable shaft 14. A placement plate 6 is fixedly installed on the top of the connecting seat 15. A fixing plate 9 is fixedly installed between the two support arms 4. A limit mechanism is provided on the fixing plate 9.

[0031] The limiting mechanism includes two fixed slots 20, which are symmetrically distributed at the front and rear ends of the fixed plate 9. A toothed plate 13 is slidably inserted into each of the two fixed slots 20, and the two toothed plates 13 are respectively engaged with the first gear 5 and the second gear 12 at corresponding positions. A number of springs 21 are fixedly installed between the end of the toothed plate 13 inside the fixed slot 20 and the inner wall of the fixed slot 20. A through slot 19 corresponding to the position and number of the fixed slots 20 is opened on the top of the fixed plate 9. A slider 16 is fixedly installed on the top of the toothed plate 13, and the slider 16 passes through the interior of the through slot 19 and is slidably connected to the through slot 19.

[0032] In one embodiment, an operating block 17 is fixedly installed on the top of the slider 16, and a baffle plate 18 is fixedly installed on the opposite surfaces of the two operating blocks 17.

[0033] In one preferred embodiment, the area of ​​the baffle 18 is larger than the area of ​​the top opening of the through groove 19, which can better block the through groove 19 and prevent foreign objects from falling into the through groove 19.

[0034] In one embodiment, a groove 10 is provided on one side of the base 1, and a handle 11 is fixedly installed inside the groove 10 for easy gripping, which significantly improves the overall portability of the bracket.

[0035] In one preferred embodiment, anti-slip pads 22 are adhered to both sides of the bottom of the base 1, which can increase the friction with the contact surface, prevent the base 1 from sliding, and improve the placement stability.

[0036] In one embodiment, the front end of the placement plate 6 is provided with symmetrically distributed folded edges 7, which can prevent the placed tablet computer from sliding forward and enhance the stability of use.

[0037] In one preferred embodiment, the placement plate 6 has symmetrically distributed heat dissipation holes 8, which facilitates air circulation, effectively accelerates the heat dissipation of the tablet computer, and prevents its performance from deteriorating due to overheating.

[0038] In one embodiment, an anti-slip coating is provided on the outer surface of the operating block 17 to increase friction and prevent the hand from slipping during operation, making it easier and more stable for the user to operate the operating block 17.

[0039] The working principle of this utility model is as follows: When using the bracket, firstly, the angle between the support arm 4 and the base 1 is adjusted. Directly move the rear operating block 17. The movement of the operating block 17 causes the slider 16 to slide on the through groove 19. At the same time, the sliding of the slider 16 causes the toothed plate 13 to move into the fixed groove 20 and compress the spring 21. As the toothed plate 13 moves, its engagement with the first gear 5 is released. At this time, flip the support arm 4 upward. When the support arm 4 is adjusted to a suitable angle, release the limit on the operating block 17. The spring 21, with its elastic restoring force, drives the toothed plate 13 to reset, so that it engages with the corresponding tooth groove on the first gear 5, thereby locking the position of the support arm 4. Subsequently, move the front operating block 17 in the same way to adjust the angle between the placement plate 6 and the support arm 4. The engagement and locking of the toothed plate 13 with the second gear 12 ensures the stability of the angle of the placement plate 6. Finally, place the tablet computer on top of the placement plate 6 for use. When storing the bracket later, simply operate the operating block 17 to change the position of the toothed plate 13, disengaging the toothed plate 13 from the meshing state of the second gear 12 and the first gear 5, and the placement plate 6 and support arm 4 can be quickly folded downwards for storage. Compared to the traditional method of using a damping shaft with high resistance for angle adjustment, this bracket achieves position positioning through a limiting mechanism. The limiting mechanism has a simple structure and is easy to operate, making the entire angle adjustment process time-saving and labor-saving, effectively improving the ease of use of the product.
