[0022] The utility model will be further explained in detail in combination with the drawings and specific embodiment.

[0023] Embodiment one;

[0024] Figure 1 And Figure 2The clutch type locking structure is applied to a satellite communication terminal. After the satellite communication terminal obtains satellite longitude and latitude parameters, the terminal obtains its own position information through a sensor, calculates angle data required for the antenna feeder system to align with the satellite, and then drives the terminal transmission system to rotate to a target angle by a motor or manpower. After the satellite signal is obtained, a satellite communication link is established to realize the reception and transmission of communication services. The clutch type locking structure in the embodiment can prevent the terminal transmission system from rotating to achieve structural locking.

[0025] Specifically, the sleeve component 1 is provided as a shell and has a hollow locking channel arranged in the axial direction. The component has a shell structure with a cylindrical channel. The driving component 2 is movably arranged at the proximal end port of the hollow locking channel. In the embodiment, the proximal end port of the hollow locking channel has a ring-shaped blocking part one 6 that reduces the inner diameter of the hollow locking channel. The ring-shaped blocking part one 6 limits the complete movement of the driving component 2 out of the hollow locking channel. The driving component 2 is in the form of a button-shaped component that matches the shape of the proximal end port of the hollow locking channel. The circumferential force is transmitted by pressing the driving component 2. The clutch gear 3 is arranged in the hollow locking channel in the axial direction and elastically abuts the distal end of the driving component 2. The clutch gear 3 is sleeved with a spring 8. The proximal end of the spring 8 abuts the front end plate 7 of the clutch gear 3. The distal end of the spring 8 abuts the boss in the hollow locking channel. The clutch gear 3 has two circumferential sliding grooves 9. The hollow locking channel of the sleeve component 1 is provided with a matching convex rib 10. The rotating gear 4 is arranged in the distal end port of the hollow locking channel in the circumferential direction and is engaged with the clutch gear 3 after axial movement. The distal end port of the hollow locking channel has a ring-shaped blocking part two 11 that reduces the inner diameter of the hollow locking channel. The ring-shaped blocking part two 11 limits the movement of the rotating gear 4 out of the hollow locking channel. The distal end of the rotating gear 4 is coaxially connected to the rotating component 5. The rotating component 5 is connected to the terminal transmission system to control the structure to rotate to the target angle.

[0026] In the initial state, the spring 8 is in the elastic opening state. The front end plate 7 of the clutch gear 3 is pushed to elastically abut the driving component 2. When the driving component 2 is rotated, the driving component 2 moves in the axial direction, compresses the spring 8, and the clutch gear 3 cannot rotate freely due to the cooperation of the sliding groove 9 on the clutch gear 3 and the convex rib 10. The clutch gear 3 moves axially under the guidance of the convex rib 10. When the clutch gear 3 moves to the meshing position with the rotating gear 4, a transmission connection is established between the gears. In the meshing state, the rotating movement of the rotating gear 4 is hindered. This axial movement and meshing method can quickly establish / disconnect the transmission connection. The convex rib guiding system ensures accurate and repeatable movement trajectories, which is more suitable for intermittent work requirements than traditional fixed gear transmission. The spring buffer reduces the risk of overload and protects the gear teeth. The elastic abutment design compensates for manufacturing and assembly errors.

[0031] The clutch gear 3 is movably arranged in the hollow locking channel along the axial direction and elastically abuts against the distal end of the driving component 2; the clutch gear 3 is sleeved with a spring 8, the proximal end of the spring 8 abuts against the front end plate 7 of the clutch gear 3, and the distal end of the spring 8 abuts against the boss in the hollow locking channel. The circumferential side wall of the clutch gear 3 has four sliding grooves 9 arranged along the circumferential direction, and the hollow locking channel of the sleeve component 1 is provided with a matching ridge 10. Different from example one, the driving component 2 can be axially displaced by pressing, which is more simple and efficient in operation than example one.

[0032] The rotating gear 4 is rotatably arranged in the distal end port of the hollow locking channel along the circumferential direction and is engaged with the clutch gear 3 after moving along the axial direction. The distal end of the rotating gear 4 is coaxially connected to the rotating component 5.

[0033] The distal end port of the hollow locking channel has a ring-shaped blocking part two 11 that reduces the inner diameter of the hollow locking channel, and the ring-shaped blocking part two 11 limits the movement of the rotating gear 4 out of the hollow locking channel.

[0034] In the initial state, the spring 8 is in the elastic opening state, the front end plate 7 of the clutch gear 3 is pushed to elastically abut against the driving component 2, when the driving component 2 is pushed, the driving component 2 moves along the axial direction, the spring 8 is compressed, the cooperation between the sliding groove 9 on the clutch gear 3 and the ridge 10 makes the clutch gear 3 unable to rotate freely, the clutch gear 3 moves along the axial direction under the guidance of the ridge 10, when the clutch gear 3 moves to the meshing position with the rotating gear 4, the transmission connection is established between the gears, in the meshing state, the rotating movement of the rotating gear 4 is hindered, this axial movement meshing mode can realize the quick establishment / disconnection of the transmission connection, the ridge guiding system ensures the accurate and repeatable movement track, which is more suitable for intermittent work requirements than the traditional fixed gear transmission; the spring buffering reduces the risk of overload and protects the gear tooth surface; the elastic abutment design compensates for the manufacturing and assembly errors.

[0035] The clutch type locking structure provided in the patent replaces the traditional friction locking by a toothed meshing mechanism, solves the limitation of the prior art which is dependent on friction, and effectively avoids the above problems. The toothed end face meshing locking is adopted to avoid performance degradation caused by material wear; the spring and sliding groove design is introduced to ensure that the clutch gear does not rotate relatively when sliding axially, and the operation stability and reliability are improved; through structural innovation, the inherent defects of the existing friction locking scheme are solved, and a more efficient and durable locking and loosening solution is provided for the satellite communication terminal in the power shortage or manpower driving scene.

[0036] The above embodiments are not a limitation of the utility model, and the utility model is not limited to the above examples, and the changes, modifications, additions or replacements made by the person skilled in the art within the technical scheme range of the utility model also belong to the protection range of the utility model.
