Detailed Description
The first embodiment is as follows:
referring to fig. 1, a space is formed between the lock body located in the lock case and the lock case. The invention just utilizes the vacant space to block the lock cylinder hole 111 after the lock cylinder is chopped and damaged.
Referring to fig. 2, 3 and 6, the lock box with the reset hole plugging device of the present invention mainly comprises a lock box body 1 and the reset hole plugging device, wherein a lock cylinder hole 111 is formed in a box wall installed on the outdoor side of the lock box body 1, and the reset hole plugging device is installed on an inner side wall 11 of the outdoor side box wall and is used for plugging the lock cylinder hole 111 after the lock cylinder 5 is cut off and damaged. Reset type hole plugging device includes plug hole apron 2, rotates canceling release mechanical system 3 and limit structure 4, rotates canceling release mechanical system 3 and connects plug hole apron 2 on lock box body 1, and limit structure 4 rigid coupling is on lock box body 1. Referring to fig. 2, before the lock core 5 is not broken and chopped, the edge of the hole plugging cover plate 2 butts against the outer contour of the lock core 5 under the action of the rotating reset mechanism 3 of the hole plugging cover plate 2. Referring to fig. 3, after the lock core 5 is cut off, the plugged cover plate 2 is driven by the rotation reset mechanism 3 to turn to the plugged cover plate 2 which plugs the lock core hole 111 and stop at the position of the limit structure 4.
The above-mentioned rotation reset mechanism 3 includes torsional spring 31 and round pin axle 32, and torsional spring 31 installs on round pin axle 32, and two torque arms of torsional spring 31 are connected with lock box body 1, blanking cover board 2 respectively. After the lock core 5 is cut off, the hole plugging cover plate 2 turns to the limiting structure 4 under the action of the torsion arm.
Referring to fig. 2 and 3, the rotational reset mechanism 3 is installed below the cylinder hole 111. Of course, the position of the rotary return mechanism 3 may be other positions around the cylinder bore 111. Referring to fig. 4 and 5, the rotation reset mechanism 3 may also be installed above the cylinder hole 111. This mounting location is selected to address the normal force application of a person to chop the failure. Because the installation position of the lock cylinder is lower, a thief applies force from top to bottom to chop the lock cylinder 5, and the operation is more convenient. Therefore, in this case, the lock case wall below the cylinder hole 111 is more easily deformed. If the rotation returning mechanism 3 is installed at the side wall below the cylinder hole 111 when the deformation is large, the rotation of the plugging cover plate 2 may be affected, but if the rotation returning mechanism is installed as shown in fig. 4 and 5, the deformation below the cylinder hole 11 has little effect on the plugging cover plate 2, and the rotation of the plugging cover plate 2 can be effectively ensured.
Of course, the installation position of the rotation returning mechanism 3 may be other positions, such as the left and right sides of the cylinder hole 111.
The limiting structure 4 is arranged on a rotating path of the plugging cover plate 2. The limiting mechanism 4 includes two limiting blocks 41, and the limiting blocks 41 include a stopper 411 and a thrust part 412. When the hole plugging cover plate 2 turns to the limiting block 41, the stopping part 411 is matched with the edge of the hole plugging cover plate 2 to limit the rotation of the hole plugging cover plate 2; when the plugging cover plate 2 is vertically applied with force from the outdoor, the thrust part 412 cooperates with the lock box body 1 to limit the movement of the plugging cover plate 2, so as to prevent the plugging cover plate 2 from separating from the inner side wall 11 of the lock box body 1.
In order to avoid the thief driving the blanking cover 2 in a rotating manner. The anti-backing structure 6 is arranged on the rotation path of the hole plugging cover plate 2, and when the hole plugging cover plate 2 rotates to the limiting structure 4, the hole plugging cover plate 2 is positioned between the limiting structure 4 and the anti-backing structure 6. The anti-retreat structure 6 includes at least one anti-retreat block 61, and the anti-retreat block 61 includes an anti-rotation portion 611 and an anti-push portion 612. When the hole plugging cover plate 2 rotates, the rotation preventing part 611 is used for limiting the rotation of the hole plugging cover plate 2; when a vertical force is applied to the blind flange 2 from the outside, the anti-pushing portion 612 cooperates with the lock case body 1 to restrict the movement of the blind flange 2.
Under the effect of the anti-retreat structure 6, the rotating hole blocking cover plate 2 is difficult to be attached to the inner side wall 11 of the lock box body 1 to rotate, and the movement track of the tail end of the hole blocking cover plate 2 relative to the anti-retreat structure 6 is in a parabola shape with the distance from the top to the bottom due to the lifting of the anti-retreat structure 6 to the hole blocking cover plate 2. In the parabolic motion track of the hole plugging cover plate 2, how to ensure that the front section of the hole plugging cover plate 2 can be smoothly matched with the limiting block 41. A guide face 413 is formed on the thrust part 412, and a wedge passage 415 is formed between the guide face 413 and the lock case body 1. When the plugging cover plate 2 moves towards the stopping part 411, the front end of the plugging cover plate 2 enters from the large opening end of the wedge-shaped channel 415 and stops at the stopping part 411.
In addition to the guiding optimization on the limiting structure 4, a guiding structure 72 can be arranged on the blind plate 2. Be equipped with spigot surface 21 on blanking cover plate 2, spigot surface 21 is located blanking cover plate 2 and prevents moving back the terminal of structure 6 sliding contact, and under the effect of spigot surface 21, the thickness of this terminal is the attenuate gradually, through this kind of form of attenuation for the front end of blanking cover plate 2 more is close to the inside wall 11 of lock box body 1. This further ensures that the blanking cover plate 2 can enter the wedge-shaped channel 415 smoothly. Meanwhile, the matching distance between the anti-retreat structure 6 and the limiting structure 4 can be reduced.
Under the condition that the matching distance between the anti-retreat structure 6 and the limiting structure 4 is reduced, the movement track of the plugging cover plate 2 is more accurate and standard, so that the design precision of the anti-retreat structure 6 and the limiting structure 4 can be improved. The accuracy is improved, and the difficulty that a thief needs to withdraw the hole plugging cover plate 2 according to a certain track is improved.
In order to reduce the instantaneous force of the blind 2 on the stopper 411, an elastic cushion 414 is provided on the stopper 411. When the blanking cover 2 is in rotational contact with the stopper 411, the elastic cushion 414 is compressed to weaken the force of the blanking cover 2 on the stopper 411. Meanwhile, the hole plugging cover plate 2 is pushed into between the anti-pushing portion 612 and the lock box body 1 by the resilience of the elastic buffer 414 to the hole plugging cover plate 2. The movement track of the hole blocking cover plate 2 is increased, so that the lock cylinder hole 111 cannot be opened by directly pushing and blocking the hole blocking cover plate 2. The difficulty of retreating the plugging cover plate 2 according to the original track is further improved.
The elastic buffer 414 may be a compression spring, a spring, or other components that are compressed when subjected to an instantaneous impact and partially recover the original elongation after the impact is over.
Example two
Referring to fig. 7 and 8, the present embodiment differs from the first embodiment in that: the sliding reset mechanism 7 is adopted to replace the rotating reset mechanism 3 in the first embodiment, and the movement form of the plugging cover plate 2 is changed. The sliding reset mechanism 7 comprises a tension spring 71 and a guide structure 72 arranged between the lock box body 11 and the hole plugging cover plate 2. Under the traction of the tension spring 71, the blind cover plate 2 slides along the guide structure 72 and stops at the limit structure 4.
In addition, the installation position of the anti-receding structure 6 in this embodiment is changed, and the position is on the track of the sliding of the hole blocking cover 2, and when the hole blocking cover 2 slides to the position of the limiting structure 4, the end of the hole blocking cover 2 also recedes to between the anti-pushing part 612 and the lock box body 1 due to the acting force of the elastic buffer 414. This prevents the blind 2 from backing off directly.
The guide structure 72 may be a conventional guide rail and guide shoe matching structure, or a rod and hole matching structure.
In addition, in the embodiment, the tension spring 71 is used for pulling the plugging cover plate 2 to move, but of course, a pressure spring can be used for pushing the plugging cover plate 2 to move.
