In the figure, a locking cover 1; an anti-rotation limit pin 11; a guide sleeve 2; a lock pin mounting hole 21; a steel ball limiting groove 22; a lock pin 3; a steel ball slot 31; a rope fixing hole 32; steel balls 4; pin mounting holes 41.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in fig. 1 to 5, an embodiment of an intelligent lock anti-reverse structure includes a lock cover 1, a guide sleeve 2 connected to the lock cover 1, a lock pin 3 inserted into the guide sleeve 2, and a steel ball 4 engaged with the lock pin 3, wherein the steel ball 4 is provided with a pin mounting hole 41, and the lock cover 1 is provided with an anti-reverse limit pin 11 inserted into the pin mounting hole 41. The anti-rotation limiting pin 11 is in clearance fit with the pin mounting hole 41, so that the steel ball 4 can swing within a certain range, but the steel ball 4 cannot rotate, external force is prevented from rotating the steel ball 4 by rotating the lock pin 3, and the steel ball 4 cannot rotate to enable the external force to be reversely unlocked, so that the purpose of preventing the reverse unlocking is achieved.
The anti-rotation limiting pin 11 and the lock cover 1 are made into a whole by adopting an integral forming process, or the anti-rotation limiting pin 11 is embedded in the lock cover 1 to form a whole.
The guide sleeve 2 is of a cylindrical structure, a lock pin mounting hole 21 is formed in the guide sleeve 2 along the axis direction, a steel ball limiting groove 22 is formed in the outer wall of the guide sleeve 2, and the steel ball limiting groove 22 penetrates through the outer wall of the guide sleeve 2. The opening of the lock pin mounting hole 21 is provided on the end face of the guide bush 2. The outer wall of the lock pin 3 is provided with a steel ball clamping groove 31, the steel ball clamping groove 31 is arranged along the outer edge of the cross section of the lock pin 3, and the section of the steel ball clamping groove 31 is of an arc structure. The lock pin 3 for connecting the rope lock is inserted into the lock pin mounting hole 41, the lock pin 3 and the guide bush 2 are coaxially fitted, and the lock pin 3 is displaced along the lock pin mounting hole 21. The lock pin 3 is provided with a steel ball slot 31 matched with the steel ball 4. The steel ball clamping groove 31 is positioned at the position matched with the steel ball limiting groove 22. The lock pin 3 is inserted into the lock pin mounting hole 21 of the guide sleeve 2, and when the steel ball 4 is matched and clamped with the steel ball clamping groove 31, the lock pin 3 is clamped to achieve the purpose of locking.
A rope fixing hole 32 is provided in the lock pin 3, and the rope fixing hole 32 extends along the central axis of the lock pin 3. One end of a rope (not shown) is fixed with the lock body, the movable end of the rope is connected with the rope fixing hole 32, and the movable end of the rope is fixed with the lock pin to form a steel wire lock beam.
As a further explanation of the present embodiment, the operation flow thereof will now be explained: after the lock pin 3 is inserted into the lock pin mounting hole 21 of the guide sleeve 2, the steel ball clamping groove 31 of the lock pin 3 is aligned with the steel ball limiting groove 22 of the guide sleeve 2; when locking is needed, the internal drive makes the steel ball 4 deviate and fall into the steel ball slot 31 of the lock pin 3; the steel ball 4 is limited by the steel ball limiting groove 22 of the guide sleeve 2, so that the lock pin 3 is clamped, and the locking process is completed. The design of this embodiment is that a rope fixing hole 32 is formed on the steel ball 4, so that the steel ball 4 can swing around the anti-rotation limit pin 11 on the lock cover 1 and can not rotate.
Other structures of this embodiment are seen in the prior art.
