[0033] 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 this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] For examples, please refer to Figure 1-9 This embodiment provides a technical solution for a rotatable folding lock: it includes a folding rod assembly, a lock housing 101, and a lock assembly disposed within the lock housing. The folding rod assembly includes a fixed locking arm 103, several connecting arms 102, and a locking arm 104. The several connecting arms 102 are connected end to end in sequence, mainly through a cap pin 110. The fixed locking arm 103 and the locking arm 104 are disposed on both sides of the connecting arms 102. The fixed locking arm 103 is installed on one side of the lock housing. The other end face of the lock housing forms a rotating end face 1018. A limiting hole groove 1012 is opened on the rotating end face 1018. The upper section of the locking arm 104 is machined with a lock side cover 109 and a lock tongue 108. The lock tongue 108 is movably connected to the locking arm 104 through a shaft 1081. The lock side cover 109 is provided with a limiting member adapted to the limiting groove. The lock housing 101 is mainly composed of an outer lock housing and an inner lock housing 1013. The inner lock housing 1013 is connected to the lock cylinder housing 1014 via a pin 1018.

[0035] The technical solution of the above approach will be explained in detail:

[0036] Several connecting arms are sequentially connected end to end to form a continuous folding rod, achieving an unfoldable or stowable structure. The locking arm 104 is installed on the other side of the connecting arm, ensuring that it corresponds to the fixed locking arm 103 and can rotate smoothly.

[0037] The mounting position for the lock side cover is machined on the upper section of the locking arm, and the lock side cover is then installed. The lock side cover should be designed with a limiting element that matches the limiting groove, ensuring that it can be securely engaged in the limiting groove in different positions when locked. Mounting holes for the lock tongue are machined on the locking arm, and the lock tongue is movably connected to the locking arm via a shaft. This ensures that the lock tongue can rotate freely.

[0038] Through the above implementation methods, a rotatable folding lock can be manufactured. This lock has the advantages of simple structure, convenient operation, and reliable safety, and is suitable for various occasions that require folding and locking.

[0039] An inner groove 115 is formed on the outer side of the lock side cover. A matching side cover 114 is installed on the inner groove 115. The side cover 114 has a side cover groove 1141. The limiting member includes a spring 113 and a steel ball 111. One end of the spring 113 extends into the side cover groove, and the other end of the spring 113 abuts against the steel ball. The side cover 114 can be connected to the lock side cover by screws.

[0040] A detailed explanation of this technical solution is provided below:

[0041] First, an inner groove is machined on the outer side of the lock side cover, and a side cover groove is made on the side cover. This groove is used to accommodate the limiting component consisting of a spring and a steel ball. Installing the limiting component: Insert one end of the spring into the side cover groove, ensuring it is securely fixed within the groove. Then, place the steel ball on the other end of the spring, using the spring's elasticity to press the steel ball firmly. When the lock tongue is engaged, the steel ball is pressed against the limiting hole groove 1012. Since the limiting hole groove 1012 has a full circle, the steel ball can be positioned within the limiting hole groove 1012 regardless of the direction of rotation, achieving fixation after rotation in different directions. During rotation, the steel ball can smoothly pop out and retract under the action of the spring.

[0042] Through this implementation method, we have successfully formed an inner groove on the outer side of the lock side cover and installed a suitable side cover on this groove. The side cover groove is used to accommodate a limiting element composed of a spring and a steel ball, achieving effective limiting and fixation of the locking arm. This design not only improves the security and stability of the lock but also ensures smooth and flexible locking and unlocking processes. It ensures that all parts of the lock can fit tightly without interference, thus providing users with a reliable and practical folding lock solution.

[0043] The rotating end face also has a circular concave guide groove 1011, and a convex ring 120 adapted to the concave guide groove is provided on the upper section of the locking arm facing the rotating end face. The convex ring is aligned with the circular concave guide groove on the rotating end face. It maintains a stable guiding effect during rotation.

[0044] The lock housing is provided with a lock hole 119 for the locking arm to be inserted. The lock assembly includes a lock cylinder 105, which is installed in a lock cavity provided inside the lock housing. A keyhole 1031 is installed at the mounting point of the locking arm 103 and the lock housing. The lock cylinder 105 is provided with a lock ring block 106, which is installed on one side of the lock cylinder and rotated by the lock cylinder 105. The lock hole 119 has a lock hole opening 1191. The locking arm has a lock tongue 108. When locked, the lock tongue 108 is in the lock hole 119, and the lock ring block 106 closes the lock hole opening 1191.

[0045] When in use, when the lock tongue is locked, the lock ring block 106 will lock the hole 1191 and restrict the lock tongue 108 to achieve locking. When it is necessary to unlock, simply turn the lock cylinder to turn the lock ring block 106, thereby opening the lock hole 1191 and allowing the lock tongue to be taken out from the lock hole 1191.

[0046] The lock cylinder 106 has a mounting rod 1052 machined on the side facing the lock block. The lock block 106 has a lock block mating hole seat mounted on the mounting rod. A torsion spring 107 is mounted on the mounting rod. One end of the torsion spring 107 is engaged with the lock block, and the other end is engaged with the lock cylinder or the mounting rod. This structure ensures the overall reliability of the lock.

[0047] refer to Figure 3 and 7 The lock cylinder is provided with a limiting ring groove 1016, and the inner wall of the lock housing is installed with a limiting pin 1017. The purpose is to allow the lock cylinder to rotate within a certain range.

[0048] refer to Figure 3The lock housing contains a pop-out component, which faces the latch of the locking arm. Specifically, the pop-out component includes a first spring 121 and a pop-out block 122. The pop-out block has an indentation. The upper end of the first spring is located in a first spring cavity within the lock housing, and the lower end of the first spring is located in the indentation within the pop-out block. This elastic block abuts against the latch of the locking arm, which is locked within the keyhole. This allows for quick removal of the locking arm by utilizing the elastic block to push out the latch, thus achieving rapid unlocking.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
