Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6A convenient unlocking and opening mechanism comprises a bin cover assembly 2 mounted on a bin opening of a bin chamber 1, the bin cover assembly 2 comprises a bin cover body 21 and a lock mechanism 22 arranged on the bin cover body 21, the lock mechanism 22 comprises a movable plate 221, a lock bearing shell 228, a lock bolt 227 and an elastic reset member 229, the movable plate 221 is rotatably connected to the bin cover body 21, the lock bearing shell 228 is fixedly connected to the bin cover body 21, and the lock bearing shell 228 is fixedly connected to the bin cover body 21. The second packaging ring 226 is packaged between the main body 21, and the second packaging ring 226 is mainly used to assist the joint seam between the sealing components, so as to improve the sealing performance of the bin cover assembly 2. The locking bolt 227 is arranged on the lock buckle bearing shell 228 and is slidably connected with the lock buckle bearing shell 228 through a guiding mechanism. The guiding mechanism includes a linear guide hole 2271 arranged on the locking bolt 227 and a guide bolt 2281 fixed on the lock buckle bearing shell 228. The guide bolt 2281 penetrates the linear guide hole 2271 and the guide bolt 2281 is fixed on the lock buckle bearing shell 228. The lock bolt 227 is slidably connected to the linear guide hole 2271, and a lock bolt through hole is opened on one side of the lock buckle bearing shell 228. One end of the lock bolt 227 can extend outward from the lock bolt through hole, and the other end is placed inside the lock buckle bearing shell 228 and elastically connected to the inner wall surface of the lock buckle bearing shell 228 through an elastic reset member 229. The elastic reset member 229 is a spring. The edge of the lock bolt 227 at one end outside the lock bolt through hole is a lower shrinkage bevel 2272. The movable plate 221 A swing arm 2211 extending outward is provided on it. When the movable plate 221 rotates relative to the compartment cover body 21 based on the initial form, the swing arm 2211 drives the locking bolt 227 to slide and displace to overcome the elastic force of the elastic reset member 229, so that one end of the locking bolt 227 located on the outside of the locking bolt through hole shrinks toward the inside of the locking bolt through hole. A blocking line 11 is provided on the wall of the compartment 1. When the compartment cover assembly 2 is covered on the compartment opening of the compartment 1, the locking bolt 227 is snap-connected with the blocking line 11.

[0023] The bin cover body 21 is provided with a movable plate mounting groove 222, and an axle seat 223 is provided at the movable plate mounting groove 222. A swing arm through hole 224 penetrating the upper and lower end surfaces of the shell is opened on the axle seat 223. The swing arm through hole 224 is symmetrically provided with axle holes 2111 on the opposite walls. A rotating shaft 2212 perpendicular to the swing arm 2211 is provided in the middle of the swing arm 2211. The end of the swing arm 2211 away from the movable plate 221 is a driving end 2213. The swing arm 2211 penetrates the swing arm 2211. The arm through hole 224 is provided, the rotating shaft 2212 is rotatably connected in the shaft hole 2111, and a yield groove 225 is provided on one side of the movable plate mounting groove 222. When the movable plate 221 rotates based on the initial form, the yield groove 225 provides a yield space for the movable plate 221 to rotate toward the compartment cover body 21 at one end. When the movable plate 221 rotates, the driving end 2213 abuts against the locking bolt 227 and pushes the locking bolt 227 to overcome the elastic force of the spring and retract toward the inside of the locking bolt through hole.

[0024] The bin cover body 21 includes an upper cover plate 211, a first sealing ring 212 and a lower cover plate 213. The upper cover plate 211 and the lower cover plate 213 are covered and connected. The first sealing ring 212 is clamped between the upper cover plate 211 and the lower cover plate 213. The first sealing ring 212 is used to seal the joint position of the upper cover plate 211 and the lower cover plate 213, so as to improve the sealing performance of the bin cover body 21.

[0025] In summary, for the present utility model, when the bin cover assembly 2 is installed on the bin opening of the bin chamber 1, the locking bolt 227 can be automatically buckled and locked with the stop line 11 by means of the lower contraction bevel 2272 by virtue of the self - gravity of the bin cover assembly 2, avoiding the occurrence of the phenomenon that the bin cover assembly 2 is left unlocked during use, and effectively ensuring the protection effect of the bin cover assembly 2. When unlocking the locking state of the bin cover assembly 2 and the bin chamber 1, only need to simply press the movable plate 221 to make it turn up, and then lift the movable plate 221 conveniently. The operation is simple and convenient, solving the problems of difficult locking and unlocking of the bin cover assembly 2 in the prior art.
