Description

Technical Field

[0001] This utility model relates to an adjustable support structure. Background Technology

[0002] A common existing rotating structure is a combination of two rectangular frames. Both frames are vertical and positioned one behind the other, with their left sides hinged together. The rear frame is fixed, while the front frame can rotate.

[0003] This hinge-based structure has revealed several problems in practical use. Because the front frame needs to rotate and is quite heavy, its weight places a significant load on the hinge joints after prolonged use. This continuous and substantial load makes the hinge joints a weak point in the entire structure, highly susceptible to damage. Damage to the hinge joints not only hinders frame rotation, affecting the normal operation of equipment or machinery, but in severe cases, it can even cause the entire support structure to fail, creating a safety hazard. Utility Model Content

[0004] In view of the problems pointed out in the background art, this utility model proposes an adjustable support structure to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An adjustable support structure includes a long strip-shaped main arm, a fixed arm, a first movable arm, and a second movable arm; one end of the fixed arm is fixedly connected to the main arm, one end of the first movable arm and the second movable arm are respectively hinged to the two ends of the main arm, and the fixed arm is located between the first movable arm and the second movable arm.

[0007] The present invention is further configured to include a long strip-shaped drive arm, which is inserted into the first movable arm and the two form a sliding fit. The position of the drive arm can be adjusted in the length direction of the first movable arm.

[0008] The present invention is further configured to include a drive device for driving the drive arm to reciprocate.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] For reference as follows Figures 1-3 The present invention will be described as follows:

[0023] Example: An adjustable support structure includes a long, narrow main arm 1, a fixed arm 2, a first movable arm 3, a second movable arm 4, a drive arm 5, a drive device 6, and two rectangular frames 12 and 13. Each component, through specific connection methods and motion relationships, achieves the functions of strengthening the frame connections and driving rotation.

[0024] One end of the fixed arm 2 is fixedly connected to the main arm 1, forming a stable basic structure for the support.

[0025] One end of the first movable arm 3 and the second movable arm 4 are respectively hinged to both ends of the main arm 1. This hinge design provides the movable arm with rotational freedom. The fixed arm 2 is located between the first movable arm 3 and the second movable arm 4, which further clarifies the spatial layout relationship of each component and ensures the stability of the overall structure of the support.

[0026] It also includes a long, narrow drive arm 5, which is a key component for realizing the movement of the support. The drive arm 5 is inserted into the first movable arm 3, and the two form a sliding fit. The position of the drive arm 5 can be adjusted along the length of the first movable arm 3. After the drive arm 5 slides to a suitable position within the first movable arm 3, it is fixed to the first movable arm 3 as a whole through a specific fixing connection method (such as bolt tightening, buckle locking, or other mechanical connection means). This adjustable and fixable connection method gives the drive arm 5 a flexible length adaptation capability.

[0027] It also includes a drive device 6 that drives the drive arm 5 to reciprocate.

[0028] By adjusting the position of the drive arm 5 to accommodate the installation of the drive device 6, the first movable arm 3 is connected to the drive device 6 via the drive arm 5. The drive device 6 controls the movement of the drive arm 5, which in turn drives the first movable arm 3 to move, causing the entire bracket to rotate.

[0029] Regarding the installation and adaptation of the drive device 6, if the drive arm 5 is missing and the first movable arm 3 is directly connected to the drive device 6, due to the fixed length of the first movable arm 3, in actual assembly, factors such as the installation position, model specifications, and overall layout of the bracket of the drive device 6 can easily lead to a mismatch in the connection length between the first movable arm 3 and the drive device 6. For example, when there is a slight deviation in the installation position of the drive device 6, or when a different specification of drive device 6 is selected, the first movable arm 3 may be too long, resulting in insufficient installation space, or too short, preventing effective power transmission. The introduction of the drive arm 5 effectively solves this problem. By adjusting the insertion depth of the drive arm 5 within the first movable arm 3, the overall length of the combined drive arm 5 and the first movable arm 3 can be precisely adjusted to adapt to the connection requirements of the drive device 6 under different installation conditions. After completing the position adjustment, the drive arm 5 and the first movable arm 3 are fixed to ensure that they form a stable force transmission structure during subsequent use, guaranteeing the reliability of power transmission.

[0030] During the support drive process, the drive device 6 acts as a power source, controlling the movement of the drive arm 5 to drive the support. The drive device 6 (such as a linear drive component like a cylinder, electric push rod, or hydraulic cylinder) outputs linear motion, directly acting on the drive arm 5. Since the drive arm 5 is fixedly connected to the first movable arm 3, the linear movement of the drive arm 5 will cause the first movable arm 3 to produce a corresponding movement. The first movable arm 3 is hinged to the main arm 1. Under the action of the driving force, the first movable arm 3 rotates around the hinge point and transmits the motion to the second movable arm 4 through the main arm 1. The second movable arm 4 is hinged to the second frame 13, ultimately driving the entire support structure to rotate, thus achieving rotational control of the second frame 13. In this process, the drive arm 5 acts as an intermediate hub for power transmission. Its adjustable connection with the first movable arm 3 ensures both the flexibility of the drive device 6 installation and the efficient and stable transmission of power to all components of the support, achieving precise motion control of the support structure.

[0031] It also includes vertically arranged rectangular frames 12 and 13. Frame 13 is located in front of frame 12. The left sides of frame 12 and frame 13 are hinged by hinge 14. The left sides of frame 12 and frame 13 are located between fixed arm 2 and second movable arm 4. The other ends of fixed arm 2 and second movable arm 4 are respectively hinged to frame 12 and frame 13.

[0032] This multi-connection-point design breaks away from the traditional single-mode reliance on hinge connections. In actual use, when frame 2 13 bears its own weight or external loads, hinge 14 is no longer the sole load-bearing component. Components such as the fixed arm 2 and the second movable arm 4 in the support structure are connected to the frame through hinge points, distributing the weight of frame 2 13 across the entire support structure. Hinges 14 and the support share the load, effectively reducing the pressure on hinge 14 and thus minimizing the risk of damage due to excessive load, significantly improving the structure's durability.

[0033] Regarding the rotation of the drive frame, when the drive device 6 drives the drive arm 5 and the first movable arm 3 to reciprocate, since the first movable arm 3 is hinged to the main arm 1, and the second movable arm 4 is also hinged to the main arm 1 and the second frame 13, the movement of the drive arm 5 will cause the first movable arm 3 to move. The movement of the first movable arm 3 is transmitted to the second movable arm 4 through the main arm 1, thereby causing the second frame 13 to rotate around the hinge 14. Throughout the process, the support structure converts the linear motion of the drive arm 5 into the rotational motion of the second frame 13 through mechanical transmission between the components, realizing precise drive control of the second frame 13 and meeting the needs of frame rotation operation in practical applications.

[0034] The drive unit 6 is a cylinder, with its piston rod hinged to the drive arm 5. This hinged structure allows the piston rod to rotate freely within a certain angle range during the movement of the drive arm 5, ensuring smooth power transmission between them. Simultaneously, the other end of the cylinder is also hinged, allowing the cylinder to move and adjust its angle accordingly as the drive arm 5 rotates during operation. This hinged connection effectively avoids motion interference problems that might occur with a rigid connection between the cylinder and the drive arm 5, ensuring the cylinder maintains a stable working state during extension and retraction, thus improving the reliability of power transmission and the stability of system operation.

[0035] The first movable arm 3 is provided with a plug-in groove 7 that runs through both ends of it, and the drive arm 5 is adapted to slide and connect with the plug-in groove 7.

[0036] The first movable arm 3 is provided with a limiting groove 8 extending through both sides of it, and the limiting groove 8 is arranged along the length direction of the first movable arm 3. The drive arm 5 is provided with a positioning hole 9 corresponding to the limiting groove 8, and the positioning hole 9 is arranged through both sides of the drive arm 5. It also includes a positioning bolt 10 connected in the limiting groove 8 and the positioning hole 9, and a fastening nut 11 is connected to the positioning bolt 10. After the positions of the drive arm 5 and the first movable arm 3 are adjusted, the drive arm 5 and the first movable arm 3 are fixed by the positioning bolt 10 and the fastening nut 11.

[0037] 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 protection scope of the present utility model.
