Example two
On the basis of the first embodiment, a unidirectional locking lock catch comprises a lock head 1 and a lock tongue 2 made of elastic materials, wherein the lock head 1 comprises a threading groove 12, a lock seat 10 and the first embodiment of a pressing device 11, the threading groove 12 is connected with the lock seat 10, the pressing device 11 is hinged with the lock seat 10 through a hinge shaft 6, one end of the hinge shaft 6 is abutted with a concave limiting groove 41 on a pressing part 4 of the pressing device 11, and a gap for the lock tongue 2 to pass through is arranged between the pressing device 11 and the lock seat 10.
Specifically, the compressing part of the compressing device 11 is of a ratchet 111 structure, the compressing device 11 further comprises a mounting seat 112, a first rotating shaft 113 and a first one-way bearing 114, the mounting seat 112 is fixed with the lock seat 10, the first rotating shaft 113 is fixed with the mounting seat 112, the first one-way bearing 114 is sleeved on the periphery of the first rotating shaft 113, and the ratchet 111 is sleeved on the periphery of the first one-way bearing 114 and rotates synchronously with the first one-way bearing 114, so that one-way rotation of the ratchet 111 is realized. The lock tongue 2 is provided with saw-shaped teeth 3, the lock tongue 2 enters the lock seat 10 through a gap between the pressing device 11 and the lock seat 10, the insertion direction of the lock tongue 2 is consistent with the rotation direction of the ratchet 111 which rotates unidirectionally, when the lock tongue 2 is inserted into the lock seat 10, the ratchet 111 rotates, after the lock tongue 2 is inserted in place, the inverted teeth on the outer periphery side of the ratchet 111 are meshed with the saw-shaped teeth 3 on the lock tongue 2 to prevent the lock tongue 2 from retreating, the tooth tip parts of the saw-shaped teeth 3 incline along the reverse direction of the insertion direction of the lock tongue 2, and the tooth tip parts on the periphery side of the ratchet 111 incline towards the rotation direction of the ratchet 111.
In this way, when the lock tongue 2 is inserted into the gap between the pressing device 11 and the lock seat 10, the ratchet 111 is rotated along the advancing direction of the lock tongue 2 by the force applied by the lock tongue 2, so that the insertion resistance of the lock tongue 2 is reduced, the lock tongue 2 is smoothly inserted, and after the lock tongue 2 is inserted in place, the saw-shaped teeth 3 on the lock tongue 2 and the teeth on the periphery side of the ratchet 111 are in a meshed state because the ratchet 111 can not rotate reversely, the locking force of the ratchet 111 on the lock tongue 2 is increased, the lock tongue 2 is further prevented from exiting the lock head 1, and the unidirectional locking of the lock catch is realized.
Specifically, the direction of inserting the lock tongue 2 into the lock head 1 is defined as a positive direction, the direction of withdrawing the lock tongue 2 from the lock head 1 is defined as a reverse direction, and when the first unidirectional bearing 114 rotates in the positive direction or the first rotating shaft 113 rotates reversely, the friction force between the first unidirectional bearing 114 and the first rotating shaft 113 is very small, and the two can rotate relatively; when the first one-way bearing 114 rotates in the opposite direction or the first rotating shaft 113 rotates in the forward direction, the friction force between the first one-way bearing 114 and the first rotating shaft 113 is large, and the two rotate synchronously. Thus, when the lock tongue 2 is inserted, the lock tongue 2 applies forward thrust to the ratchet 111, and the ratchet 111 and the first one-way bearing 114 rotate forward under the action of the thrust, so that the lock tongue 2 can be smoothly inserted; when the latch 2 is about to withdraw from the lock base 10, the latch 2 applies a reverse thrust force to the ratchet 111, and under the action of the thrust force, the ratchet 111 and the first one-way bearing 114 have a reverse rotation tendency, and in this direction, the first one-way bearing 114 and the first rotating shaft 113 cannot rotate relatively, and the first rotating shaft 113 is fixed together with the mounting base 112, so that the ratchet 111 cannot rotate reversely at this time, thereby preventing the latch 2 from withdrawing from the lock base 10, and realizing the one-way locking of the lock catch.
Further, the compressing device 11 further includes a second one-way bearing 115 and a second rotating shaft 116, the second one-way bearing 115 is turned in accordance with the first one-way bearing 114 and is coaxially arranged in the ratchet 111, one end of the second rotating shaft 116 passes through the second one-way bearing 115 to be rotationally connected with the mounting seat 112, and the other end passes through the first rotating shaft 113 to be rotationally connected with the mounting seat 112. When the second one-way bearing 115 rotates in the forward direction or the second rotating shaft 116 rotates in the reverse direction, the friction force between the needle roller of the second one-way bearing 115 and the outer wall of the second rotating shaft 116 is very small, the two can rotate relatively, and when the second one-way bearing 115 rotates in the reverse direction or the second rotating shaft 116 rotates in the forward direction, the friction force between the needle roller of the second one-way bearing 115 and the outer wall of the second rotating shaft 116 can be very large, and the two can rotate synchronously as a whole, so that after the bolt 2 is inserted, when the insertion amount of the bolt 2 is wanted to be finely adjusted, the aim can be achieved by rotating the second rotating shaft 116 in the forward direction.
Further, one end of the second rotation shaft 116 extends out of the mounting seat 112 and is sleeved with the pressing portion 4, and the pressing portion 4 rotates synchronously with the second rotation shaft 116, so that the second rotation shaft 116 can be rotated by rotating the pressing portion 4.
Further, one end of the compressing device 11 is hinged to the lock seat 10 through the hinge shaft 6, specifically, the inserting end of the installation seat 112, which is located on the lock tongue 2, is hinged to the lock seat 10 through the hinge shaft 6, the pressing portion is provided with a concave limiting groove, the pressing portion 4 is internally provided with a reset torsion spring 5, the reset torsion spring 5 is sleeved at the end of the second rotation shaft 116, and two supporting legs of the reset torsion spring 5 are respectively abutted to the pressing portion 4 and the installation seat 112. When the pressing part is reset through the torsion of the reset torsion spring, the concave limiting groove is abutted against the hinge shaft, and the pressing part 4 can be restored to the original position after each adjustment through the torsion of the reset torsion spring 5; thereby control the reset displacement of the pressing part, the rotation angle of the pressing part 4 is smaller, and the insertion amount of the fine tuning bolt 2 is convenient, thereby realizing the effect of fine tuning.
The working process and beneficial effects of the invention are as follows: when the lock tongue 2 is inserted into the lock seat 10, the ratchet 111 rotates positively, so that the insertion resistance of the lock tongue 2 is reduced, the lock tongue 2 can be inserted smoothly, and after the lock tongue 2 is inserted in place, the ratchet 111 cannot rotate reversely, so that the resistance of the lock tongue 2 exiting the lock head 1 is increased, the lock tongue 2 cannot exit the lock head 1, and the unidirectional locking of the lock catch is realized.
In summary, this embodiment can only lock, can not the unblock, is applicable to locking the article that need unblock infrequently, is unsuitable reuse, and because only unidirectional rotation through ratchet 111 locks spring bolt 2, so the minimum fine setting volume of this embodiment can be less than the advance volume that spring bolt 2 brought that ratchet 111 rotated the angle of a tooth.
Example III
The one-way locking lock catch is different from the second embodiment in that an elastic piece for enabling the ratchet 111 to abut against the lock tongue 2 is arranged between the lock seat 10 and the mounting seat 112, the elastic piece is a compression double torsion spring 7, the compression double torsion spring 7 is sleeved on the periphery of the hinge shaft 6, the middle shaft of the compression double torsion spring 7 abuts against the mounting seat 112 of the compression device 11, two supporting legs abut against the lock seat 10 respectively, and the compression device 11 abuts against the lock tongue 2 through the compression double torsion spring 7. In this way, the hinge shaft 6 is used as the center, the lock seat 10 is rotated towards the direction away from the lock tongue 2 by pressing the elastic force of the double torsion spring 7, and the ratchet 111 can be separated from the lock tongue 2, so that the lock tongue 2 is unlocked by releasing the locking of the ratchet 111 to the lock tongue 2, and the lock tongue 2 can be withdrawn from the lock head 1, thereby realizing unlocking of the lock catch.
Further, the extension part 8 is arranged at one end, which is far away from the installation seat 112 and is hinged with the lock seat 10, of the extension part 8, the extension part 8 is arc-shaped and extends towards the direction far away from the lock seat 10, and the installation seat 112 is conveniently rotated towards the direction far away from the lock tongue 2 by hands through the extension part 8, so that the unlocking of the ratchet 111 to the lock tongue 2 is realized.
The working process and beneficial effects of the invention are as follows: when the lock tongue 2 is inserted into the lock seat 10, the ratchet 111 rotates positively, so that the resistance of the insertion of the lock tongue 2 is reduced, the lock tongue 2 can be inserted smoothly, and after the lock tongue 2 is inserted in place, the resistance of the lock tongue 2 exiting the lock head 1 is increased because the ratchet 111 cannot rotate reversely, so that the lock tongue 2 cannot exit the lock head 1, and the unidirectional locking of the lock catch is realized; when the lock catch needs to be unlocked, the extension part 8 is propped by hands to rotate the mounting seat 112 in a direction away from the lock catch 2, so that the ratchet 111 is separated from the lock catch 2, and the lock catch 2 can be withdrawn from the lock catch 1, thereby realizing unidirectional locking of the lock catch.
In sum, the embodiment can realize unidirectional locking and unlocking, can be repeatedly used for many times, can realize the unlocking function without tools, and is suitable for various locks needing to be frequently unlocked; since the locking bolt 2 is locked by only one-way rotation of the ratchet 111, the minimum fine adjustment amount of this embodiment may be smaller than the advance amount of the locking bolt 2 caused by the rotation of the ratchet 111 by one tooth angle.
