Examples

As shown in fig. 1-4, a folding lock comprises a lock body part 1 and a folding rod part 2, the folding rod part 2 comprises a plurality of rods movably connected with each other, and is convenient to fold when not in use, one end of the folding rod part 2 is fixed on the lock body part 1 and can be fixed by welding or screw fixation, and the other end is movably connected with the lock body part 1, in this embodiment, the movable end of the folding rod is connected with the lock body part 1 by plugging, and then locked and connected by a lock body, when locked by the lock body, the movable end of the folding rod is locked on the lock body part 1, the lock body part 1 comprises a fixed part fixedly connected with the folding rod part 2 and a movable head 3 rotating relative to the fixed part, a lock pin 4 moving towards one end of the movable head 3 is arranged in the fixed part, the movable head 3 is provided with a slot 31 for inserting the end of the, the end of the folding lever part 2 inserted into the insertion slot 31 is provided with a detent 21, and the locking pin 4 in the fixing part extends into the detent 21 of the folding lever part 2 when the lock body part 1 is in the locked state. In this embodiment, the lock body part 1 is provided with the movable head 3, the movable head 3 can rotate at 360 degrees, the folding rod can be paired at any angle, the applicability to the locked object is strong, and the locking is more convenient and faster.

Furthermore, the clamping position 21 at the end of the folding rod part 2 is a clamping hole, and the clamping hole is arranged by a through hole in the embodiment, so that the folding rod can be inserted or installed from any direction without influencing the use of the folding rod, and the assembly efficiency is improved.

In order to rotate 360 degrees between the movable head 3 and the fixed part, the fixed part is provided with an annular groove 71, the movable head 3 is provided with a clamping pin 5 extending to the annular groove 71 of the fixed part, the movable head 3 is sleeved on the fixed part, and the clamping pin 5 is clamped into the annular groove 71 of the fixed part, so that the movable head 3 can rotate relative to the fixed part. The movable head 3 and the fixed part are matched through the bayonet 5 and the annular groove 71 to realize 360-degree rotation of the movable head and the fixed part, and the structure is simple and convenient to realize.

It is further noted that the fixing portion of the lock body portion 1 includes a housing, an inner core 6, an inner core fixing member 7 and a lock pin 4, the lock pin 4 is movably connected in the inner core fixing member 7, the lock pin 4 is driven to reciprocate by rotation of a rotation portion of the inner core 6, in this embodiment, the inner core rotation portion and the lock pin are driven by a connecting rod 8, the key rotation portion is screwed to rotate in a correct state of the key, the lock pin is driven to reciprocate by the connecting rod, the inner core 6 is clamped on the inner core fixing member 7, the inner core fixing member 7 is fixed in the housing, and the inner core fixing member extends into or retracts into a clamping hole of the rod portion folding portion 2 by reciprocating. The ring groove 71 is formed in the circumferential direction of the core fixing member 7 in this embodiment.

In order to prevent the movable head 3 from falling off the inner core fixing element 7, the number of the clamping pins 5 is at least two, and the clamping pins 5 are tightly matched with the movable head 3. The bayonet 5 is designed into at least two pins which can ensure the connection strength between the movable head 3 and the inner core fixing piece 7, and the phenomenon that the movable head 3 falls off from the inner core fixing piece 7 by adopting single force to break off is prevented.
