When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for the purpose of illustration only.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] Embodiments, please refer to Figures 1-7 The present embodiment provides a technical solution:
[0026] A new type of folding lock, including folding rod assembly, lock shell and lock assembly arranged in the lock shell, the folding rod assembly includes fixed lock arm 31, a plurality of connecting arms 33 and locking arm 32, a plurality of connecting arms 33 are connected in turn, the head and tail of connecting arm 32 are connected in turn by movable column 15, that is, the two connecting arms are movable, forming a movable joint, the fixed lock arm 31 and the locking arm 32 are arranged on both sides of the connecting arm 33, which also adopts the above movable structure, this structure is currently used in folding lock, which will not be described in detail, the fixed lock arm 31 and the locking arm 32 are connected with the side wall of the lock shell 13, the purpose is to facilitate storage, the fixed lock arm 31 is fixedly installed on one side of the lock shell, the lock shell 2 is provided with a lock hole for inserting the locking arm, the lock assembly includes a lock cylinder 9 and a lock block 8, the lock cylinder is installed on the lock shell, the lock cylinder column 91 is installed below the lock cylinder, the lock block 8 is provided with an inner recess travel groove 80, the lock block 8 is provided with a lock tongue 7 facing the direction of the lock hole, the lock cylinder column 91 is arranged on the inner recess travel groove 80, and the other side of the lock block 8 is provided with an elastic element 10 for abutting against the side end of the lock block.
[0027] The scheme utilizes the insertion of the lock cylinder key, then rotates, and the lower lock cylinder column 91 moves in the inner recess travel groove 80 by rotating, referring to Figure 7 , which is the locking state, that is, the side wall of the inner recess travel groove 80 and the lock cylinder column are in contact with each other, if unlocking is needed, only need to rotate, then push the lock block to move, the elastic element is deformed under pressure, the lock tongue 320 is separated from the lock hole opened by the locking arm, that is, the locking arm can be opened.
