Description

Technical Field

[0001] This utility model relates to the field of radio frequency communication, and in particular to a radio frequency communication double slip ring height adjustment mechanism. Background Technology

[0002] With the development of wireless communication technology, slip rings, as the core structure for realizing the transmission of radio frequency signals, data and electrical energy between static and rotating parts, are widely used in radar, satellite communication, turntable measurement and control systems and other scenarios. In some specific applications, multiple slip rings are stacked and installed, and their height needs to be flexibly adjusted to adapt to the needs of different device structures.

[0003] Traditional slip ring installation methods mostly use fixed brackets, which lack height adjustment capabilities and cannot achieve precise spacing control between different slip rings. At the same time, the lack of a reliable locking mechanism can easily cause the slip ring assembly to shift due to vibration or load changes during operation, affecting signal integrity and structural stability. Therefore, there is an urgent need for a simple, easy-to-adjust, and reliable double slip ring height adjustment mechanism to improve assembly efficiency and operational stability. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a radio frequency communication dual slip ring height adjustment mechanism, aiming to solve the problems of inconvenient installation and fixing, low adjustment accuracy, and unreliable locking in the existing technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a radio frequency communication dual slip ring height adjustment mechanism, including a frame assembly, a sliding adjustment component disposed within the frame assembly, and a positioning and locking component. The positioning and locking component includes a rotating handle disposed at the upper end of the frame assembly, a cam sleeved at the lower end of the rotating handle, and a connecting rod abutting against the cam. The outer contour of the cam includes a convex surface and a concave surface. When the rotating handle drives the cam to rotate until the convex surface faces the connecting rod, the cam presses against the connecting rod to fix the sliding adjustment component relative to the frame assembly. When the rotating handle drives the cam to rotate until the concave surface faces the connecting rod, there is a gap between the cam and the connecting rod, and the sliding adjustment component can freely slide up and down within the frame assembly for adjustment.

[0006] Based on the above structural design, the eccentric cam is rotated by rotating the handle. When the convex surface of the cam faces the connecting rod, it presses the connecting rod downward, thereby achieving a reliable lock between the sliding adjustment component and the frame component, making the structure stable after height adjustment. When the handle is rotated further until the concave surface aligns with the connecting rod, a gap is formed between the cam and the connecting rod, allowing the sliding adjustment component to slide up and down within the frame component. This enables convenient height positioning and repeated adjustment. This structure is not only simple to operate and flexible to adjust, but also effectively prevents displacement caused by external vibration during operation. It has good mechanical self-locking performance and is particularly suitable for applications in radio frequency communication where precise adjustment of slip ring height and stability are required, significantly improving adjustment efficiency and structural reliability.

[0007] Furthermore, the frame assembly includes a base, an upper positioning ring, and a plurality of guide rods, wherein the plurality of guide rods and the connecting rods connect the base and the upper positioning ring.

[0008] Based on the above, the guide rod and connecting rod form a circumferentially distributed multi-point support within the frame assembly, effectively improving the rigidity and deformation resistance of the overall structure. This provides a stable guide path for the sliding adjustment assembly, ensuring smooth operation and preventing wobbling during vertical adjustment. Simultaneously, the connecting rod, as the pressure-bearing component of the cam in the positioning and locking assembly, cooperates with the cam to form a reliable fulcrum during locking, thereby enabling the sliding adjustment assembly to achieve precise positioning at the target height and remain stable. This improves the positioning accuracy and repeatability of height adjustment, enhancing the adaptability and structural safety of this invention in a radio frequency communication environment.

[0009] Furthermore, the sliding adjustment assembly includes several connecting rods, a first slip ring, a second slip ring, and a support platform disposed on the base. The several connecting rods respectively connect the support platform to the first slip ring and the first slip ring to the second slip ring. The sliding adjustment assembly slides along the guide rod and the connecting rod to adjust the height.

[0010] Based on the above, the connecting rod connects multiple functional components into one unit, realizing a compact modular linkage adjustment. The first and second slip rings, as the core motion units in height adjustment, can slide up and down in the vertical path defined by the guide rod and connecting rod, thereby driving the overall lifting and lowering of the bearing platform. This structural design not only makes the adjustment stroke controllable, but also ensures stable movement and smooth operation, reducing the risk of jamming due to offset or tilt. At the same time, the first and second slip rings, through the upper and lower level combination connection method, optimize the overall center of gravity and mechanical structure of the sliding component, further improving the stability and load-bearing capacity of the mechanism, and meeting the requirements of precise positioning and reliable contact of radio frequency communication equipment at different heights.

[0011] Furthermore, a cushioning pad is provided on the base, and the cushioning pad is located at the bottom of the support platform.

[0012] Based on the above, the buffer pad, as the lower contact component of the support platform, can act as a buffer limit when the sliding adjustment component descends to the lowest point. It absorbs the impact caused by inertia or external force during the adjustment process, prevents direct hard contact between the platform and the base, reduces structural wear and vibration transmission, and improves the overall durability and operational stability of the mechanism. In addition, the buffer pad also has a certain degree of flexibility and recovery capability, which helps to maintain the initial height reference and repeatability of the support platform, thereby improving the tolerance and stability of the double slip ring mechanism to small displacement errors in actual radio frequency communication systems.

[0013] Furthermore, a buckle is provided at the bottom of the rotating handle, and a slot is provided at the bottom of the first slip ring. Rotating the rotating handle locks the buckle in the slot.

[0014] Based on the above, by setting a matching structure between the buckle and the slot, the buckle can automatically insert into the slot after the rotating handle completes the locking action, thereby limiting and fixing the rotating handle, preventing the cam position from shifting due to vibration or external force, enhancing the stability and anti-interference ability of the locking state, further ensuring that the height of the sliding adjustment component remains consistent during use, and improving the reliability and safety of the whole mechanism in radio frequency communication equipment.

[0015] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0017] like Figures 1-6As shown, this utility model is a radio frequency communication double slip ring height adjustment mechanism, including a frame assembly 1, a sliding adjustment component 2 disposed within the frame assembly 1, and a positioning and locking component 3. The positioning and locking component 3 includes a rotating handle 30 disposed on the upper end of the frame assembly 1, a cam 31 sleeved on the lower end of the rotating handle 30, and a connecting rod 32 abutting against the cam 31. The outer contour of the cam 31 includes a convex surface and a concave surface. When the rotating handle 30 drives the cam 31 to rotate until the convex surface faces the connecting rod 32, the cam 31 presses against the connecting rod 32 to fix the sliding adjustment component 2 relative to the frame assembly 1. When the rotating handle 30 drives the cam 31 to rotate until the concave surface faces the connecting rod 32, there is a gap between the cam 31 and the connecting rod 32, and the sliding adjustment component 2 can freely slide up and down within the frame assembly 1 for adjustment.

[0018] The frame assembly 1 includes a base 10, an upper positioning ring 13, and a plurality of guide rods 12, wherein the plurality of guide rods 12 and the connecting rods 32 connect the base 10 and the upper positioning ring 13.

[0019] The sliding adjustment assembly 2 includes several connecting rods 20, a first slip ring 21, a second slip ring 22, and a support platform 23 disposed on the base 10. The several connecting rods 20 respectively connect the support platform 23 to the first slip ring 21 and the first slip ring 21 to the second slip ring 22. The sliding adjustment assembly 2 slides along the guide rod 12 and the connecting rod 32 to adjust the height.

[0020] A buffer pad 11 is provided on the base 10, and the buffer pad 11 is located at the bottom of the support platform 23.

[0021] The bottom of the rotating handle 30 is provided with a buckle 4, and the bottom of the first slip ring 21 is provided with a slot 5. Rotating the rotating handle 30 locks the buckle 4 into the slot 5.

[0022] In summary, the specific embodiments of this utility model are as follows: When in use, the operator first rotates the handle 30 to the unlocked state. At this time, the handle 30 drives the cam 31 at its lower end to rotate, so that the concave surface of the cam 31 faces the connecting rod 32. A gap is formed between the cam 31 and the connecting rod 32, and the positioning locking component 3 is in the unlocked state, so that the sliding adjustment component 2 can slide freely in the vertical direction within the frame component 1.

[0023] Subsequently, the operator manually pulls the rotating handle 30 or pushes the bearing platform 23 to cause the connecting rod 20, the first slip ring 21 and the second slip ring 22 to slide up and down along the guide rod 12 and the connecting rod 32, thereby realizing the height adjustment of the bearing platform 23 to meet the spatial adaptation or installation position requirements between the slip rings.

[0024] After the sliding adjustment component 2 is adjusted to the target height, the operator rotates the rotary handle 30 again, so that the convex surface of the cam 31 faces the connecting rod 32. During the rotation, the cam 31 presses against the connecting rod 32, thereby limiting the vertical direction of the sliding adjustment component 2 and completing the positioning and locking. At the same time as the locking is completed, the buckle 4 set at the bottom of the rotary handle 30 is inserted into the corresponding slot 5 at the bottom of the first slip ring 21, forming an additional mechanical limit to prevent the rotary handle 30 from disengaging from the locked state due to vibration or external force, thus improving the stability of the structure and the reliability of repeated use. The bottom of the sliding adjustment component 2 is provided with a buffer pad 11, which is used to buffer the bearing platform 23 during the adjustment and sliding process, effectively preventing mechanical impact caused by collision, and improving the service life of the overall structure and the safety of operation.

[0025] In summary, the height adjustment process of this utility model has the characteristics of flexible adjustment, reliable locking, and simple operation. It is suitable for application scenarios in radio frequency communication where the position of the double slip ring is frequently adjusted, and is especially suitable for system structures with high requirements for installation height accuracy and stability.

[0026] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
