[0019] Lock buckle 1, locking portion 11, gasket 111, locking nut 12, linkage rod 121, inner embedding groove 13, outer embedding groove 14, locking handle 2, rod groove 21, cross bar 211, and movable cavity 22. DETAILED DESCRIPTION
[0020] Specific embodiment 1: Please refer to Figure 1-5 A reinforced umbrella hoop comprises a lock buckle 1 and a locking handle 2, wherein the locking handle 2 is rotatably connected to one side of the lock buckle 1.
[0021] The lock buckle 1 is a circular ring sleeve, with an opening at one end, and the walls on both sides of the opening of the lock buckle 1 extend outward to form a locking portion 11 and a tightening portion respectively. The outer edge of the locking portion 11 is concave to form a locking arc, and the side end face of the locking arc is also provided with a gasket 111 symmetrical along the middle of the side end face. The gasket 111 is fixedly connected to the locking arc end face, and the curvature of the gasket 111 is the same as the curvature of the locking arc, so that the gasket 111 is completely fitted on the locking arc end face in the locking portion 11. A through hole that passes through the wall of the lock buckle 1 is transversely opened on the side wall away from the opening end. A locking nut 12 is embedded in the through hole, and the radius of the locking nut 12 is the same as the size of the through hole, and the locking nut 12 is threadedly connected to the through hole. The locking nut 12 also includes a linkage rod 121, which is arranged at both ends of the locking portion 11 and the tightening portion of the lock buckle 1. A rotation hole is formed in the vertical direction at one end of the linkage rod 121 near the locking part 11, and the locking handle 2 is rotatably connected to the rotation hole. An inner groove 13 is formed on the inner ring surface of the lock buckle 1, so that the umbrella rod abuts against the inner groove 13 for effective position limiting. An outer groove 14 is formed on the outer ring surface of the lock buckle 1, which matches the abutment arc of the locking handle 2, so that the locking handle 2 can abut against the outer groove 14 for position limiting after being locked.
[0022] The locking handle 2 is located at the side end of the locking portion 11, and one end of the locking handle 2 always abuts against the gasket 111. The locking handle 2 includes an abutting end and a tail end. A rod groove 21 is provided in the middle of the abutting end, and the rod groove 21 runs through the locking handle 2. A cross bar 211 is also embedded in the rod groove 21. The cross bar 211 is embedded in the rotation hole of the linkage rod 121 and extends to both ends of the locking handle 2. The cross bar 211 is rotatably connected in the rotation hole so that the locking handle 2 is rotatably connected to the linkage rod 121. The abutting end is provided with an arc near the end surface of the locking portion 11. The arc of the locking abutting end is equal to the locking arc and the arc of the gasket, so that the abutting end of the locking handle 2 can abut against the gasket 111. An active cavity 22 is provided in the middle of the side end of the abutting end of the locking handle 2, and the active cavity 22 runs through the side wall of the abutting end. The opening height of the movable cavity 22 is greater than the diameter of the linkage rod 121, so that the linkage rod 121 is placed in the movable cavity 22. When the locking handle 2 is in the open state, the end of the linkage rod 121 close to the movable cavity 22 abuts against the upper end of the movable cavity 22 to limit the opening and closing of the locking handle 2. The opening of the movable cavity 22 forms the abutting end of the locking handle 2 with an upper and lower abutting end, and the upper and lower abutting ends abut against the gasket 111 respectively, and the abutting area size of the upper and lower abutting ends and the gasket 111 matches the abutting area size of the gasket 111, so as to increase the locking degree between the locking handle 2 and the lock buckle 1 through the gasket 111.
[0023] Under normal circumstances, the abutting end of the locking handle 2 always abuts against the gasket 111; when locking the lock buckle, the tail end of the locking handle 2 moves toward the outer wall of the lock buckle 1, so that the abutting end of the locking handle 2 rotates along the locking arc of the locking part 11 and remains in contact with the gasket 111.
[0024] Working principle:
[0025] When the utility model is used, the locking handle and the linkage rod are rotatably connected by the cross bar embedded in the rotation hole of the linkage rod, and the cross bar is fixedly connected with the rod groove 21 at the abutting end of the locking handle, so as to realize the rotation connection between the locking handle and the linkage rod. The linkage rod passes through both sides of the lock buckle opening end through the locking nut to realize the rotation of the locking handle and the lock buckle. When the locking handle rotates, since the abutting end of the locking handle always abuts on the gasket, the locking effect is increased, so that the locking handle and the lock buckle are locked more tightly.
