Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1-2, a lifebuoy discharging device comprises a fixing plate 1, a movable cavity 2 is arranged in the fixing plate 1, a sliding groove 3 is arranged on the inner top wall of the movable cavity 2, a plurality of mounting grooves 4 are equidistantly arranged on the inner bottom wall of the movable cavity 2, a motor 14 is embedded in the inner wall of one side of the sliding groove 3, a threaded rod 15 is fixedly connected with the output end of the motor 14, one end of the threaded rod 15, far away from the motor 14, is rotatably connected with the inner wall of the other side of the sliding groove 3, a sliding block 16 is sleeved on the threaded rod 15 in a threaded manner, a triangular plate 17 is fixedly connected with the lower end of the sliding block 16, the triangular plate 17 is an isosceles triangle, swinging grooves 13 are symmetrically arranged on the inner bottom wall of the mounting groove 4, rotating shafts 10 are rotatably connected with the inner walls of the two sides of the mounting grooves 4, gears 12 are coaxially and fixedly sleeved on the rotating, its fixed structure, for prior art, common meshing has two-way pinion rack 6 between two gears 12, and the common fixedly connected with reset spring 9 of the common bottom wall of the lower extreme of two-way pinion rack 6 and mounting groove 4, two-way pinion rack 6, gear 12 and clamping bar 11 return under reset spring 9's effect normal position, and extrusion wheel 8 is installed through the fork arm to the upper end of two-way pinion rack 6. The downward moving distance of the bidirectional toothed plate 6 is matched with the swinging angle of the clamping rod 11, namely when the guide rod 5 abuts against the inner top wall of the guide groove 7, the clamping rod 11 abuts against the inner wall of the swinging groove 13.
