Description

TECHNICAL FIELD

[0001] The present application relates to the field of machinery, in particular to a rod locking mechanism. BACKGROUND

[0002] The current antenna array rod locking mechanism is complex, heavy and inconvenient to assemble and disassemble. When assembling and disassembling, multiple fasteners and antenna outer skeletons and other structural components need to be assembled and disassembled. The present application is applied to a quick assembly and disassembly antenna array device, which has the characteristics of adapting to high complexity of erection site, quick erection, repeated assembly and disassembly, light weight, easy maintenance, etc.

[0003] The antenna array has high sensitivity to its installation position in terms of gain and signal coverage range, so when installing the antenna array, its position and angle need to be carefully adjusted to ensure the best signal strength. The antenna array rod locking mechanism is very critical to the position and angle of the antenna array installation, that is, the antenna array needs to be locked on the truss or other support rod.

[0004] The current rod locking mechanism generally uses screws and other fasteners to fasten the antenna side and bottom to the truss or other support rod, or uses intermediate parts for adapter fixing, etc. This clamping method is complex to operate, easy to damage the clamp body, and the clamp body itself is heavy, making it difficult to achieve infinite adjustment of the position. The butterfly nut, U-shaped clamp and other clamping devices cannot manually clamp the rod with a large torque, generally need to use a wrench as an auxiliary tool, and cannot achieve the function of being loose and not falling off. SUMMARY

[0005] In order to overcome the shortcomings of the prior art, the present application provides a rod locking mechanism applied to a quick assembly and disassembly antenna array. In view of the problems of complex operation of the locking mechanism during the current antenna array erection on the rod, the need for tool assistance, the disadvantage of repeated assembly and disassembly, and the low disassembly efficiency, the present application provides a rod locking mechanism applied to a quick assembly and disassembly antenna array.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] A rod locking mechanism for quick assembly and disassembly of an antenna array includes a locking mechanism 1, a fastener 2, an antenna array body 3, and a side bracket 4. The locking mechanism 1 locks the antenna array body 3 onto the side bracket 4. The locking mechanism 1 is fastened to the antenna array body 3 by the fastener 2. The locking mechanism 1, the fastener 2, and the antenna array body 3 do not separate and are in a long-term connected state. The antenna array body 3 and the locking mechanism 1 are locked together by the locking cover 16 and the locking seat 17 under the locking force applied by the handle 15.

[0028] The locking mechanism 1 includes a limiting fastener 11, a limiting ring 12, a screw 13, a locking pin 14, a handle 15, a locking cover 16, and a lock seat 17. The lock seat 17 is located on the ground, and the locking cover 16 is provided on the lock seat 17. After the lock seat 17 and the locking cover 16 are closed, there is an axial through hole. The lock seat 17 and the locking cover 16 are hinged by the locking pin 14. The locking cover 16 rotates around the locking pin 14. A screw 13 is longitudinally provided at the hinge of the locking cover 16. The handle 15 is L-shaped. The screw 13 passes through the longitudinal part of the handle 15. The top of the screw 13 is provided with a limiting ring 12, and the fastener 11 is provided above the limiting ring 12.

[0029] The locking cover 16 has a U-shaped groove at its rotating end. The front end of the U-shaped groove is an arc-shaped flared opening, which facilitates the locking mechanism 1 so that the screw 13 is guided by the groove to quickly rotate to the corresponding position when locking.

[0030] The rotating end of the locking cover 16 is provided with a wedge-shaped protrusion. When the lateral part of the handle 15 rotates downward, the lower end face of the handle 15 is guided by the wedge-shaped protrusion, and the locking cover 16 quickly completes the locking. Under harsh external environmental conditions, the wedge-shaped protrusion can play a role in preventing loosening.

[0031] The rotating and fixed ends of the locking cover 16 are both designed with reinforcing ribs to enhance the strength of the locking cover.

[0032] The handle 15 has a slot at the top, a threaded hole in the middle, and a smooth hole at the bottom. The screw 13 has a threaded section in the middle, and smooth sections at the top and bottom. The top of the screw 13 has a threaded groove for the limit fastener 11 to press the limit ring 12. When the locking mechanism 1 is in the disassembly state, when the handle 15 moves to the top, it is blocked by the limit ring 12, preventing the handle thread from rotating and disengaging from the screw thread, thus providing a non-disengaging function.

[0033] The thickness of the lock seat 17 is greater than that of the locking cover 16. The protruding ribs on both sides of the lock seat 17 and the inner wall of the locking cover 16 are locked together on the side bracket 4 to prevent loosening caused by deformation of the locking mechanism.

[0034] The bottom of the lock seat 17 is slotted to reduce the weight of the entire locking mechanism 1 itself. The lock seat 17 is designed with reinforcing ribs on both sides to enhance its strength.

[0035] The locking pin 14 and the locking seat 17 are interference fit, and the protruding end of the locking pin 14 uses a shaft elastic retaining ring 18 to further prevent loosening.

[0036] When locking, the locking seat 17 is in contact with the side bracket 4 at a fixed position. Flipping the locking cover 16 puts the locking mechanism 1 into a closed state. Lifting the handle 15 and rotating the screw 13, the screw 13 passes through the U-shaped groove of the locking cover 16 and contacts the bottom of the U-shaped groove. Rotating the handle 15, the threaded extrusion force generated by the handle 15 and the screw 13 locks the locking cover 16, the side bracket 4 and the locking seat 17. When the locking mechanism 1 is loosened, rotating the handle 15 in the opposite direction, the thread is disengaged and the handle 15 is lifted. The handle 15 and the screw 13 rotate together around the locking pin 14 to ensure that they are completely disengaged from the locking cover 16. Flipping the locking cover 16 disengages the locking mechanism 1 from the side bracket 4, thus completing the disassembly of the antenna array body 3 and the locking mechanism 1.

[0037] A rod locking mechanism for quick assembly and disassembly of antenna arrays, wherein the locking mechanism (1) locks the antenna array body (3) onto the tube support (4), and mainly includes: a limiting fastener (11), a limiting ring (12), a screw (13), a locking pin (14), a handle (15), a locking cover (16), and a locking seat (17).

[0038] The handle (15) has a slot at the top, a threaded hole in the middle, and a smooth hole at the bottom. The screw (13) has a threaded section in the middle and smooth sections at the top and bottom. The screw (13) has a threaded groove at the top for the limit fastener (11) to press the limit ring (12). When the handle (15) moves up and down due to rotation, the limit ring (12) is always on the screw (13). When the locking mechanism (1) enters the disassembly state, the handle (15) moves to the top and is blocked by the limit ring (12), thus having the function of not being loosened.

[0039] The locking cover (16) has a U-shaped groove at its rotating end. The front end of the U-shaped groove is designed as an arc-shaped flared mouth, which is beneficial for the locking mechanism (1) to quickly rotate the screw (13) to the corresponding position when it is locked. The locking cover (16) has a wedge-shaped protrusion at its rotating end, which is beneficial for the lower end face of the handle (15) to be guided when the handle (15) is rotated downwards. The handle (15) and the locking cover (16) can quickly lock together. Under harsh external environmental conditions, the wedge-shaped protrusion can also play a role in preventing loosening.

[0040] In this invention, the locking mechanism uses a rotating handle for locking, which can apply a large torque and lock quickly; when disassembling, the rotating handle is released, and the handle and screw disengage from the U-shaped groove of the locking cover to complete the disassembly. The structure is independent and compact, and the connection relationship is clear.
