Detailed Description

In order to make the utility model realize that the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to be understood, the utility model is further explained by combining the embodiment.

Example 1

Referring to the accompanying drawings 1 to 9, the lock limiting mechanism comprises a lock body 1, wherein the lock body 1 is a cylinder, two opposite through holes are formed in the side wall of the lock body 1, and a lock cylinder 2 is arranged in each through hole in a penetrating mode. The lock cylinder 2 is a transverse T-shaped block, a lower support column 21 of the lock cylinder is inserted into the through hole, an end head 22 at the top of the lock cylinder blocks the outside of the lock body 1, and meanwhile, the insertion limit of the lock cylinder 2 is realized. The lower support column 21 is arranged in the lock body 1 in a penetrating manner, the lower end face of the lower support column is provided with an inclined guide part 23 which can specifically comprise an inclined plane, and when the trigger piece 5 moves upwards to abut against the guide part 23 in use, the lock cylinder 2 is pushed out of the lock body 1 under the action of horizontal component force.

When the trigger 5 is not actuated, the two lock cylinders 2 are restrained by a retainer such as a tension spring 3. The tension springs 3 draw the lock cylinders 2 on the two sides in a balanced manner, and the lock cylinders are kept in a state of being tightly inserted into the through holes, so that the lock cylinders 2 are mutually drawn, centered and synchronously moved.

Specifically, the side wall of the lock body 1 is further provided with a through hole for avoiding the tension spring 3, two ends of the tension spring 3 penetrate through the lock body 1 respectively and are correspondingly connected to the lock cylinder 2, the lock cylinder 2 is pulled towards the interior of the lock body 1 together, and the normal locking state of the lock cylinder 2 is kept.

Located outside the lock body 1 and lock cylinder 2 is a sleeve 4. The inner side wall of the lock sleeve 4 is protruded inwards along the radial direction to form a circle of annular steps 41. When in use, the step 41 is positioned at the periphery of the lock body 1 and below the lock cylinder 2. The lock cylinder 2 is mutually fixed with the lock sleeve 4 under the blocking of the step 41.

In order to unlock, a plurality of unlocking openings 42 are formed in the step 41, and when the lock is used, the lock core 2 can be disengaged from the block of the step 41 by rotating the position of the lock core 2 to the unlocking openings 42, so that unlocking is realized.

Further, in order to realize the controllable unlocking and the safety of locking, in this embodiment, a blocking portion 43 is disposed beside the unlocking port 42, and the blocking portion 43 is located at a position close to the inner edge of the platform, that is, an avoiding space is left between the blocking portion 43 and the inner wall of the lock sleeve, so as to avoid the tip 22 of the lock cylinder 2. During the use, under the normality, lock core 2 adduction under the effect of extension spring 3 reaches the position with stop part 43 parallel and level, and stop part 43 blocks lock core 2 and rotates on step 41 circumference, has realized the safe locking to lock core 2 and lock body 1. When unlocking is needed, the trigger piece 5 moves upwards along the axial direction of the lock body 1, the lock core 2 is pushed out of the lock body 1 according to the principle, the end head 22 of the lock core 2 extends outwards and goes over the blocking part 43, the blocking part 43 does not have the circumferential blocking capacity for the lock core 2 at the moment, then the lock core 2 and the lock body 1 are rotated, the end part of the lock core 2 bypasses the blocking part 43 and is rotated to the position radially aligned with the unlocking port 42, the pressure of the trigger piece 5 on the lock core 2 is relieved at the moment, the lock core 2 is enabled to be inwards retracted to the position aligned with the unlocking port 42 along the radial direction under the action of the tension spring, and the lock core 2 and the lock body 1 can be pulled out of the lock sleeve 4 along the axial direction.

It should be noted that the lower part of the trigger 5 is a cylindrical base 51, and the upper part is an unlocking block 52. The cylindrical side wall at the lower part of the trigger part 5 is provided with a limit strip 6. The inner wall of the lock body 1 is provided with a limit groove 7 matched with the limit strip 6. When the lock is used, the limiting strip 6 of the trigger piece 5 is clamped into the limiting groove 7 in a sliding mode, and when the trigger piece 5 rotates, the lock body 1 and the lock cylinder 2 are driven to rotate relative to the lock sleeve 4 by means of the matching of the limiting strip 6 and the limiting groove 7.

In this embodiment, the usage environment of the lock limiting structure is: the lock sleeve 4 is fixedly arranged at the bottom of the automobile, the lock body 1 is fixed in the vehicle-mounted mobile power supply assembly, and the trigger 5 is fixed by unlocking equipment such as a mobile unlocking platform (RGV trolley). When the vehicle-mounted power supply assembly is used, the unlocking platform is moved to a position right facing the lock body 1, then the lock body 1 is driven to unlock, the lock body 1 is separated from the lock sleeve 4, and the vehicle-mounted power supply assembly is unlocked from the automobile chassis.

The technical scheme can be applied to an automobile certainly, the automobile can adopt any one of the lock limiting mechanisms, and optionally, the lock sleeve 4 is fixedly arranged at the bottom of the automobile; the lock body 1 is fixed in the vehicle-mounted mobile power supply assembly; the trigger 5 is secured by an unlocking device.

Example 2

On the basis that the other technical scheme of the embodiment 1 is kept unchanged, the lock cylinder 2 can be set to be in a conical structure. The lock core 2 is left outside the lock body 1 and is a big end, and the lock core 2 is inserted into the lock body 1 and is a small end; the big end can not pass through the through hole on the lock body 1 so as to limit the insertion limit of the small end.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, but rather that the principles of the invention may be embodied in other specific forms without departing from the spirit or scope of the invention. The scope of the invention is defined by the appended claims and equivalents thereof.
