Description

Technical Field

[0001] This utility model provides a multi-angle support structure, belonging to the field of control arm technology, and particularly relates to a multi-angle support structure for a control arm. Background Technology

[0002] Existing control arm support structures are primarily used to provide stable support and angle adjustment in various application scenarios, and are widely used in robotic arms, lighting equipment, display stands, and other fields. Their core function is to achieve the fixing and adjustment of the connecting arm at multiple angles through mechanical structure design, thereby meeting the installation and usage requirements of different equipment.

[0003] Existing control arm support structures typically employ simple slot or bolt fixing methods. The basic structure consists of a fixed connecting arm and a rotatable support arm, secured together by bolts or slots. While this design allows for some angle adjustment, existing structures usually require tools to tighten or loosen the bolts, making the adjustment process cumbersome, time-consuming, and inconvenient for rapid assembly and disassembly. Existing slot designs generally only allow for limited angle adjustments, failing to meet the needs of multi-angle, fine-tuned adjustments, especially in scenarios requiring frequent angle adjustments, resulting in a poor user experience. Due to the need for additional tools and complex operating procedures, existing support structures are not portable and struggle to meet the needs of mobile devices or temporary installations. In some designs, the connecting arm may not achieve stable locking after adjustment, making it prone to loosening under stress and affecting support stability. Existing support structures are typically only adaptable to specific equipment or scenarios, lacking versatility and flexibility, making them unsuitable for various application scenarios. Utility Model Content

[0004] In order to solve the above problems, this application provides a multi-angle support structure for the control arm, which solves the problems of complex operation, poor portability and unstable locking of traditional support structures.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-angle support structure for a control arm, including a connecting arm, one end of which is internally connected to a main rod through a limiting groove, and the other end of the main rod is externally fitted with a pressing structure;

[0006] The main rod includes a connecting rod with a circular cross-section and a locking end integrally connected to the connecting rod with a regular polygonal cross-section. The locking end is located at the end of the connecting rod away from the pressing structure.

[0007] The pressing structure includes an adjusting rod that passes through the connecting rod at the end away from the engaging end. The adjusting rod is an inclined rod with an inclination range of 30-60°. Both ends of the adjusting rod are integrally connected to inclined ends, and the outer side of the inclined ends is fitted with buttons corresponding to itself.

[0008] Preferably, the limiting groove includes a movable groove with a circular cross-section and a locking groove corresponding to the locking end. The diameter of the movable groove is not less than the diagonal length of the locking groove. The fixed rotation angle of the connecting arm is 180° - an integer multiple of the angle within the cross-section of the locking end.

[0009] Preferably, the button has a reset spring fixedly connected to the connecting rod inside, and a limiting protrusion corresponding to the inclined end and integrally connected to itself; the knob is covered with a limiting shell corresponding to the purple color.

[0010] Preferably, the limiting shell has an inner limiting sleeve fitted over the connecting rod, and the adjusting rod passes through the inner limiting sleeve.

[0011] Preferably, the end of the connecting arm away from the limiting groove is fixedly connected to the limiting shell, and the other side of the connecting arm is fixedly connected to the limiting plate and the limiting shell, which together clamp the other connecting arm.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This device achieves portable and quick multi-angle support through ingenious mechanical structure design. When the support angle needs to be adjusted, the operator simply presses down the button. This action moves the adjusting rod along the tilt angle towards the connecting rod. Since the adjusting rod passes through the connecting rod, its movement causes the connecting rod to slide upwards, which in turn moves the locking end at its other end upwards simultaneously. After the locking end disengages from the locking groove in the limiting groove, the connecting arm can rotate freely within the movable groove of the limiting groove, achieving flexible angle adjustment. After adjusting to the appropriate position, the button is released. At this time, the adjusting rod loses external force, and under the elastic restoring force of the return spring, the connecting rod drives the locking end to reset. The locking end is then precisely re-engaged into the corresponding locking groove of the limiting groove, quickly completing the angle locking. The entire process is simple and quick, requiring no additional tools, fully demonstrating the portability and speed of the device.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2As shown, a multi-angle support structure for a control arm includes a connecting arm 1. One end of the connecting arm 1 is connected to a main rod 3 via a limiting groove 2. The main rod 3 includes a connecting rod 5 with a circular cross-section and a locking end 6 with a regular polygonal cross-section, integrally connected to the connecting rod 5. The locking end 6 is located at the end of the connecting rod 5 away from the pressing structure 4. The pressing structure 4 includes an adjusting rod 7 that passes through the end of the connecting rod 5 away from the locking end 6. Both ends of the adjusting rod 7 are integrally connected to inclined ends 8, and the inclined ends 8 are sleeved with... The button 9 has a corresponding button. Inside the button 9, there is a reset spring 12 that is fixedly connected to the connecting rod 5, and a limiting protrusion 13 that corresponds to the inclined end 8 and is integrally connected to itself. The knob 9 is covered with a limiting shell 14. The limiting shell 14 has an inner limiting sleeve 15 that is fitted inside the connecting rod 5. The end of the connecting arm 1 away from the limiting groove 2 is fixedly connected to the limiting shell 15. The other side of the connecting arm 1 is fixedly connected to a limiting plate 16 and the limiting shell 15, which together clamp the other connecting arm 1.

[0025] In this implementation scheme, the components work closely together to achieve efficient and convenient multi-angle support and locking functions. On the one hand, through the cooperation of the limiting groove 2 and the engaging end 6, and the elastic action of the return spring 12, the connecting arm 1 can be easily separated and rotated freely when the angle needs to be adjusted, without the need for additional tools, making it highly portable. On the other hand, the unique tilting design of the adjustment rod 7 and the linkage structure of the button 9 not only make operation simple, but also allow for rapid reset and locking the connection arm 1 the moment the button 9 is released, ensuring stability of the connecting arm 1 at any selected angle. This effectively improves the practicality and reliability of the support structure and expands its application scenarios and scope of application.

[0026] like Figure 3 and Figure 4 As shown, the adjusting rod 7 is an inclined rod with an inclination range of 30-60°. The limiting groove 2 includes a movable groove 10 with a circular cross-section and a locking groove 11 corresponding to the locking end 6. The diameter of the movable groove 10 is not less than the diagonal length of the locking groove 11. The fixed rotation angle of the connecting arm 1 is 180° - an integer multiple of the angle in the cross-section of the locking end 6. The internal limiting sleeve 15 is penetrated by the adjusting rod 7.

[0027] In this implementation scheme, the composition and parameter design of each component are all centered around the portability and functionality of the lifting device. The adjusting rod 7 adopts an inclined design with an inclination range of 30-60°. This angle range is based on ergonomics and mechanical principles, ensuring both convenient force application when the operator presses down the button 9 and rapid rebound of the adjusting rod 7 under the action of the return spring 12. The limiting groove 2 consists of a circular movable groove 10 and a locking groove 11 corresponding to the locking end 6. The diameter of the movable groove 10 is not less than the diagonal length of the locking groove 11. Specifically, the ratio between the diameter of the movable groove 10 and the diagonal length of the locking groove 11 is rigorously calculated to ensure that the locking end 6 can move smoothly in the unlocked state and accurately engage in the locked state, preventing loosening. The fixed rotation angle of connecting arm 1 is an integer multiple of 180° minus the angle within the cross-section of the engaging end 6. For example, if the engaging end 6 is a regular hexagon with an interior angle of 120°, then the fixed rotation angle of connecting arm 1 is 180° - 120° = 60°. This design allows connecting arm 1 to achieve stable support at multiple preset angles. The internal limiting sleeve 15 is penetrated by the adjusting rod 7, and its material is typically high-strength engineering plastic or lightweight alloy, ensuring both structural strength and reduced overall weight for easy portability. The combination of these parameters and materials achieves an optimal balance between portability and functionality, meeting the needs for rapid assembly and stable support in various scenarios.

[0028] It should be noted that, in different application scenarios, the multiple connecting arms 1 of this device can adopt various connection methods to adapt to different equipment installation and support requirements. The following are some common connection schemes:

[0029] 1. Multi-angle docking of identical connecting arms

[0030] When multiple identical connecting arms 1 need to be connected, this can be achieved through the cooperation of the limiting groove 2 and the engaging end 6. The engaging end 6 of each connecting arm 1 can be inserted into the limiting groove 2 of another connecting arm 1. By operating the adjusting rod 7 and the button 9, the engaging end 6 can be fixed or rotated within the limiting groove 2. This connection method is suitable for scenarios that require the construction of multi-angle support structures, such as multi-joint robotic arms or adjustable support systems.

[0031] 2. Connection between the connecting arm and external equipment

[0032] When connecting arm 1 needs to be connected to other equipment, it can be secured using the limiting housing 14 and the inner limiting sleeve 15. The limiting housing 14 can be designed to match the interface of the external equipment and can be connected to the external equipment by means of bolts or clips. The inner limiting sleeve 15 is fitted over the connecting rod 5 and provides additional support and positioning functions to ensure the stability of the connection. For example, in an industrial robot, connecting arm 1 can be connected to the robot's base or other components through the limiting housing 14 to form a stable support structure.

[0033] 3. Connection between the connecting arm and the building structure

[0034] When it is necessary to fix the connecting arm 1 to the building structure, anchors or embedded parts can be used for connection. The limiting shell 14 can be designed with an interface that matches the anchor, and can be connected to the building structure by means of bolts or welding. At the same time, the internal limiting sleeve 15 can provide additional support to prevent the connecting arm 1 from shifting or loosening under stress. This connection method is often used in scenarios that require long-term fixed support, such as outdoor billboard brackets or temporary support structures in building construction.

[0035] 4. Cascaded connection of multiple connecting arms

[0036] When more complex support structures are required, multiple connecting arms 1 can be cascaded. The limiting groove 2 of each connecting arm 1 can be connected to the engaging end 6 of other connecting arms 1 to form a multi-level support structure. By operating the adjusting rod 7 and the button 9, the angle of each connecting arm 1 can be adjusted, thereby constructing a support system with multiple degrees of freedom. This connection method is suitable for scenarios that require flexible adjustment of shape and angle, such as foldable exhibition display racks or adjustable lighting equipment brackets.

[0037] 5. Connection between the connecting arm and the rotary joint

[0038] In scenarios requiring rotation, the connecting arm 1 can be connected to a rotary joint. The limiting groove 2 can be designed to match the axis of the rotary joint, and the connecting arm 1 can rotate by engaging with the axis of the rotary joint through the locking end 6. The adjusting rod 7 and the button 9 can be used to lock or release the rotary joint, ensuring that the connecting arm 1 remains fixed or rotates freely when needed. This connection method is commonly used in devices requiring multi-directional adjustment, such as rotatable camera brackets or joints of robotic arms.

[0039] 6. Combination of connecting arm and flexible connector

[0040] In support structures requiring a certain degree of flexibility, the connecting arm 1 can be used in conjunction with flexible connectors such as springs or elastic ropes. The limiting groove 2 and the engaging end 6 can serve as fixing points between the connecting arm 1 and the flexible connector. By operating the adjusting rod 7 and the button 9, the connecting arm 1 can achieve multi-angle support under the constraint of the flexible connector. This connection method is suitable for scenarios requiring a certain degree of cushioning and flexibility, such as support structures for sports equipment or deformable furniture designs.

[0041] The multiple connecting arms 1 of this device, through the combination of key components such as limiting grooves 2, engaging ends 6, adjusting rods 7, and buttons 9, can achieve various connection methods to adapt to different application scenarios. Whether it is the docking of identical connecting arms, connection to external equipment, fixation to building structures, cascading connection, combination with rotary joints, or combination with flexible connectors, the device can ensure connection stability and convenient adjustment, meeting diverse needs.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
