[0031] The following describes a rotary hook lock assembly provided by some embodiments of the present utility model with reference to the accompanying drawings.
[0032] Embodiment 1:
[0033] Combined with Figures 1-3 As shown, the rotary hook lock assembly provided by the present utility model includes a rotary lock body lower shell 110, a rotary lock body upper shell 120 sleeved on one end of the rotary lock body lower shell 110, a plurality of self-tapping screws 130 connected between the rotary lock body lower shell 110 and the rotary lock body upper shell 120, a gear shaft 140 inserted into the rotary lock body lower shell 110, a compression spring 150 disposed inside the rotary lock body lower shell 110 and sleeved outside the gear shaft 140, a lock core 160 movably connected between the rotary lock body lower shell 110 and the gear shaft 140, two cylindrical pins 170 installed inside the gear shaft 140 and engaged with the lock core 160, a dust-proof sheet 180 attached to the outer end of the lock core 160 and attached to the inner wall of the rotary lock body lower shell 110, and a rotary cover 190 screwed to the rotary lock body upper shell 120, and the rotary cover 190 is attached to the outside of the dust-proof sheet 180.
[0034] Furthermore, a viewing hole 111 is provided on one side of the rotary lock body lower shell 110. The provision of the viewing hole 111 facilitates the user to observe and control the device.
[0035] Furthermore, the plurality of self-tapping screws 130 are arranged at equal intervals in a circular pattern, and the two cylindrical pins 170 are horizontally symmetric with respect to the lock core 160. Adopting this layout design can improve the firmness between the rotary lock body upper shell 120 and the rotary lock body lower shell 110.
[0036] Further, an O-ring seal 400 and a hole-type metal retaining ring 500 are sleeved outside the gear shaft 140. The O-ring seal 400 is located between the upper shell 120 of the rotary lock body and the hole-type metal retaining ring 500. An axial elastic retaining ring 600 is installed inside the lower shell 110 of the rotary lock body. The axial elastic retaining ring 600 is located inside the compression spring 150, and the axial elastic retaining ring 600 is sleeved outside the lock core 160. By providing the O-ring seal 400 and the hole-type metal retaining ring 500, it is possible to prevent dust from entering the inside of the lower shell 110 of the rotary lock body and the gear shaft 140.
[0037] Embodiment 2:
[0038] Combined with Figures 1-3 As shown, on the basis of Embodiment 1, a fixing block 200 is sleeved outside the gear shaft 140.
