[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5This embodiment of a combination lock toy includes a first lock case 1 and a second lock case 2, which are connected by an internally threaded tube. The key feature is that the first lock case 1 has two limiting posts 9 inside, and a reset lock frame 5 is also movably installed inside the first lock case 1. The reset lock frame 5 is a strip-shaped frame missing from the back, and ear blocks are provided on both sides of the reset lock frame 5. Limiting holes 8 are provided on both sides of the reset lock frame 5, and the two limiting holes 8 are respectively located on the ear blocks on both sides of the reset lock frame 5. The two limiting posts 9 are respectively embedded inside the two limiting holes 8. Pressure grooves 1 are provided on both sides of the reset lock frame 5. 1. A concave groove is used to limit the movement of the reset lock frame 5. A connecting rod 13 is installed between the interior of the reset lock frame 5 and the lock housing 1. A lock head 4 is fixedly installed on the top of the connecting rod 13, and the top of the lock head 4 extends to the top of the lock housing 1. A spring 3 12 is sleeved on the outer surface of the connecting rod 13. A limiting member is also provided between the inner wall of the front of the lock housing 1 and the interior of the reset lock frame 5 to limit the spring 3 12 and the connecting rod 13. A strip-shaped hole or a circular hole is opened at the bottom of the limiting member so that the bottom of the connecting rod 13 can pass through. The interior of the lock housing 1 has two latch switch structures 7 for limiting the two pressure grooves 11.
[0023] The front of the lock housing 1 has a lock hole 14 and a lock handle 3. The lock handle 3 is fixedly installed to the reset lock frame 5 by bolts passing through the lock hole 14. The interior of the lock housing 1 also has two unlocking structures 6 for unlocking the latch switch structure 7.
[0024] It should be noted that the middle of the interior of the lock housing 1 allows the reset lock frame 5 to move up and down under the action of the two limiting holes 8 and the limiting post 9. The bottom of the lock head 4 is located inside the reset lock frame 5, and the top locking block extends to the top of the reset lock frame 5. When the reset lock frame 5 is pulled down, it will cause the bottom of the lock head 4 to press down. If no downward force is applied to the reset lock frame 5, the reaction force of the spring 312 will cause the lock head 4 to push up and restore the lock head 4 to the limit of the lock housing 1.
[0025] Specifically, when using a combination lock toy, first assemble the latch switch structure 7 and the unlocking structure 6 inside the lock housing 1. Then, press the lock head 4, connecting rod 13, and spring 3 12 inside the lock housing 1. The top of the lock head 4 needs to extend to the top of the lock housing 1 through the lock head telescopic hole. Next, press the limiting holes 8 on both sides of the reset lock frame 5 into the two limiting posts 9 and fasten the top of the reset lock frame 5 onto the lock head 4. Then, use bolts to fix the back insert of the lock handle 3 through the lock hole 14 and the reset lock frame 5. After fixing, the lock housing 1 needs to be sealed and fixed to the back of the lock housing 2 and the lock housing 1 using bolts to complete the assembly.
[0026] In this embodiment, the latch switch structure 7 includes a positioning shaft 701, a triangular locking frame 702, a second spring 703, and a pressure angle 704. The positioning shaft 701 is fixedly installed on the inner wall of the front of the lock housing 1. The triangular locking frame 702 is movably fitted on the outer surface of the positioning shaft 701. The other end of the second spring 703 is fitted on the outer surface of the cylindrical column. The triangular locking frame 702 also has a shaft hole that is clearance-fitted with the positioning shaft 701. Two inclined spring limiting members 10 are also fixedly installed on the inner wall of the front of the lock housing 1. One end of the second spring 703 is located inside the spring limiting member 10, and the other end of the second spring 703 is in contact with the inclined surface of the bottom of the conical angle of the triangular locking frame 702 on the side away from the reset locking frame 5. A cylindrical column is provided on the inclined surface of the bottom of the conical angle of the triangular locking frame 702 on the side away from the reset locking frame 5. The pressure angle 704 is located on the conical angle of the triangular locking frame 702 on the side close to the reset locking frame 5.
[0027] Specifically, when the latch switch structure 7 needs to be released from the two pressure grooves 11 on the reset lock frame 5, the protrusion 605 on the unlocking structure 6 can be rotated to press the conical angle of the triangular lock frame 702 away from the reset lock frame 5. After being pressed, the triangular lock frame 702, with the positioning shaft 701 as the center, drives the conical angle of the triangular lock frame 702 away from the reset lock frame 5 to press the spring 703, thereby causing the pressure angle 704 of the triangular lock frame 702 close to the reset lock frame 5 to disengage from the two pressure grooves 11 on the reset lock frame 5. Finally, the lock handle 3 is pulled up and down to achieve the unlocking effect.
[0028] In this embodiment, the unlocking structure 6 includes a rotating handle 601, a positioning rod 602, a spring 603, a limiting sleeve 604, a protrusion 605, and an arc-shaped groove 606. The limiting sleeve 604 is disposed inside the lock housing 1, the protrusion 605 is mounted on the outer surface of the limiting sleeve 604, and the arc-shaped groove 606 is formed on the annular bottom edge of the limiting sleeve 604. One end of the positioning rod 602 is fixed to the limiting sleeve 604 by bolts, and the other end of the positioning rod 602 penetrates through the front of the lock housing 1 and extends to its outside. The front of the lock housing 1 has a circular hole through which two positioning rods 602 and two springs 603 can pass. The rotating handle 601 is fixedly connected to the other end of the positioning rod 602, and the spring 603 is sleeved between the limiting sleeve 604 and the rotating handle 601.
[0029] It should be noted that the back of the lock case 1 has two through holes through which the back round shaft of the limiting sleeve 604 can pass. The two through holes are respectively fitted with the back round shaft of the two limiting sleeves 604. When the back round shaft of the two limiting sleeves 604 is pressed, the arc groove 606 of the limiting sleeve 604 can be restricted on the limiting pin inside the lock case 1 to limit the limiting sleeve 604.
[0030] Specifically, when the unlocking structure 6 is needed to unlock the latch switch structure 7, the rotating handle 601 can be rotated, which in turn causes the positioning rod 602 to rotate. Since the other end of the positioning rod 602 is connected to the limiting sleeve 604 by bolts, the limiting sleeve 604 is rotated. While the limiting sleeve 604 is rotating, it also causes the protrusion 605 to rotate, which further causes the protrusion 605 to rotate and squeeze the latch switch structure 7, thereby disengaging the fixing part on the latch switch structure 7 from the reset lock frame 5 to achieve the unlocking effect.
[0031] The working principle of the above embodiments is as follows:
[0032] 1. The assembly principle of the combination lock toy is as follows: First, the lock head 4, connecting rod 13, and spring 3 12 are pressed into the inside of the lock housing 1. The top of the lock head 4 needs to extend to the top of the lock housing 1 through the lock head telescopic hole. Next, the limiting holes 8 on both sides of the reset lock frame 5 are pressed into the two limiting posts 9, and the top of the reset lock frame 5 is fastened to the lock head 4. Then, the back insert of the lock handle 3 is fixed to the reset lock frame 5 by passing through the lock hole 14 with bolts. At the same time, the limiting sleeve 604 is installed between the two circular holes inside the lock housing 1. Finally, the positioning rod 602 connected to the rotating handle 601 is bolted to the limiting sleeve 604. Before the positioning rod 602 is connected to the limiting sleeve 604, the spring 603 needs to be fitted onto the outside of the positioning rod 602. Then, the back of the limiting sleeve 604 is closed by rotating the round shaft. After the unlocking structure 6 is installed, the triangular lock bracket 702 is inserted into the positioning shaft 701. Then, the spring 703 is installed between the spring limiting part 10 and the round column on the inclined surface of the tapered corner of the triangular lock bracket 702 away from the reset lock bracket 5. The pressure angle 704 on the triangular lock bracket 702 is embedded into the pressure groove 11 opened in the reset lock bracket 5 for limiting. After the latch switch structure 7 is installed, the lock shell 2 can be fixed with bolts to complete the entire installation.
[0033] 2. Working principle of the combination lock toy: First, by rotating the two rotating handles 601, the positioning rod 602 is rotated, causing the limiting sleeve 604 connected to the positioning rod 602 to drive the protrusion 605 to squeeze the conical angle of the triangular lock frame 702 away from the reset lock frame 5. This further causes the inclined surface of the conical angle on one side of the triangular lock frame 702 to squeeze the spring 703. After being squeezed, the pressing angle of the triangular lock frame 702 near the reset lock frame 5 will disengage from the pressing groove 11 opened in the reset lock frame 5. This allows the user to push the lock handle 3 up and down, causing the reset lock frame 5 to pull the connecting rod 13 and the lock head 4 down under the action of the limiting hole 8 and the limiting post 9. When the user does not apply any pulling force, the reset lock frame 5 will reset the lock head 4 to the locked state through the spring 12, completing the entire combination lock unlocking process.
