[0033] Example 1: Figure 1-11As shown in the figure, a luggage lock with an improved push button structure includes a lock body, which includes a shell 200 for assembling the password component 100. The side of the shell 200 is provided with a push button 300 that is arranged around the shell 200 and cooperates with the password component 100 to unlock and lock. The side of the shell 200 is provided with a guide groove 210 for the reciprocating movement of the push button 300. The lock body is opened and closed by the reciprocating movement of the push button 300 in the guide groove 210. This application surrounds the push button 300 around the entire side of the shell 200, and the corresponding guide groove 210 cooperates with it to form a through groove structure, so that the three sides of the push button 300 can be completely accommodated in the guide groove 210, making the lock body as a whole very beautiful. The usage method is detailed below.

[0034] The push button 300 has a square cross-section. A mounting hole 310 is provided at the center of the push button 300 for being sleeved on the outside of the guide groove 210. The lock body is opened and closed by the reciprocating motion of the mounting hole 310 in the guide groove 210. The push button 300 is designed to be a square structure because it conforms to the appearance characteristics of the luggage lock. Secondly, the closed structure makes the push button 300 stronger. Thirdly, it can better hide the three sides and make the lock body more beautiful.

[0035] The guide groove 210 is provided with a through hole 211 connected to the interior of the shell 200, and the push button 300 is provided with a lock tongue 320 for locking with the password component 100. The lock body is opened and closed by the lock tongue 320 entering and exiting the through hole 211. The lock tongue 320 enters and exits at the position of the through hole 211. The shell 200 is assembled and fixed by the upper shell 220 and the lower shell 230, and can be fixed by screws.

[0036] The push button 300 is provided with a push portion 330 for conveniently pushing the push button 300, and a recessed portion 340 is provided on the push button 300 and relative to the other side of the push portion 330 for avoiding human hands. The push portion 330 is arranged on the side of the lock tongue 320, which is more in line with the principle of mechanics. Since the push button 300 of the present application is a closed structure, the unlocking method when designing this push button 300 is basically to place the thumb on the push portion 330 and the index finger and / or middle finger on the recessed portion 340. Figure 5 As shown, if the thumb directly pushes the push portion 330, the index finger or middle finger may become resistance when unlocking. Therefore, adding the recessed portion 340 can leave more space for the index finger and the middle finger to alleviate the resistance caused by the push button 300, which is highly practical. The recessed portion 340 can be designed as a groove-shaped or inclined structure.

[0037] The guide groove 210 is provided with an elastic device 350 for preventing the push button 300 from opening the lock body. The elastic device 350 preferably adopts a spring structure, which is easy to assemble and low in cost.

[0038] The bottom of the housing 200 is provided with a lock head 400 and a connecting seat 500 mounted on the box body. One side of the housing 200 is rotatably matched with the connecting seat 500, and the other side is unlocked and locked by the cooperation of the lock head 400 and the push button 300. The lock head 400 and the connecting seat 500 are both mounted on the box body. The housing 200 is rotatably connected to the connecting seat 500 through the pin shaft 240. After the lock body is unlocked, one end of the housing 200 is tilted with the pin shaft 240 as the central axis, as shown in the attached figure. Figure 3 shown.

[0039] The password assembly 100 includes a first password wheel 110 and a first matching wheel 120 that rotate with the housing 200. The first password wheel 110 and the first matching wheel 120 are linked together. A first wheel shaft 130 for assembling the first matching wheel 120 is provided in the housing 200. The axial direction of the first wheel shaft 130 is perpendicular to the movement direction of the push button 300. A locking block 140 for preventing the push button 300 from moving is provided in the housing 200. The locking block 140 is movably connected to the housing 200 and has a swing angle. A groove 121 is provided on the first matching wheel 120, and a convex portion 121 is provided on the locking block 140 to match the groove 121. 141. When the password is correct, the lock block 140 is snapped into the groove 121 through the protrusion 141 and avoids the lock tongue 320 to unlock the lock body. In this embodiment, the directions of the first wheel shaft 130 and the push button 300 are perpendicular to each other. The matching structure of this part can be found in publication number CN212837222U, entitled "A Linked Lock Body with a Lock Cylinder". The first matching wheel 120 is provided with a protrusion 122, and the first password wheel 110 is provided with a slot 111 that matches the protrusion 122. The first matching wheel 120 and the first password wheel 110 are linked by the protrusion 122 being snapped into the slot 111 to achieve linkage.

[0040] A first lock core 600 is provided on one side of the lock block 140, and a first rotating block 610 that cooperates with the first lock core 600 is provided on the first lock core 600. When the first rotating block 610 rotates with the first lock core 600, the first rotating block 610 forces the lock block 140 to avoid the lock tongue 320 by toggling the lock block 140 to unlock the lock body. Adding the first lock core 600 to the lock body improves practicality. When the correct key is inserted and rotated, the first rotating block 610 and the first lock core 600 will rotate. The first rotating block 610 causes the lock block 140 to swing to the other side of the lock block 140 relative to the first wheel shaft 130, and the lock block 140 also leaves the lock tongue 320 to achieve the purpose of unlocking.

[0041] Directions:

[0042] In the locked state, which is equivalent to the case where the password is wrong, the first matching wheel 120 presses against the locking block 140, and the front end of the locking block 140 presses against the push button 300. At this time, the push button 300 cannot be unlocked;

[0043] When unlocking with a password, the correct password is entered, and the groove 121 on the first mating wheel 120 corresponds to the protrusion 141 on the lock block 140. At this time, the front end of the lock block 140 is tilted to avoid the push button 300. The push button 300 can now be pushed, and the lock tongue 320 on the push button 300 is separated from the lock head 400 to complete the unlocking. After unlocking is completed, just snap the housing 200 back into the lock head 400, scramble the password and wait for the next unlocking;

[0044] When using the key to unlock, insert the paired key and rotate it, the first rotating block 610 and the first lock core 600 will rotate. While rotating, the first rotating block 610 will move the rear end of the lock block 140, and the front end of the lock block 140 will also be lifted to avoid the push button 300 to achieve the purpose of unlocking.

[0045] Example 2: Figure 12-18 As shown in the figure, the difference between this embodiment and Example 1 is that the password assembly 100 includes a second password wheel 150 and a second matching wheel 160 that rotate with the housing 200, and the second password wheel 150 and the second matching wheel 160 are linked together. A second wheel shaft 170 for assembling the second matching wheel 160 is provided in the housing 200. The axial direction of the second wheel shaft 170 is parallel to the movement direction of the push button 300. A slider 321 for contacting the second wheel shaft 170 is provided on the lock tongue 320. A protrusion 171 is provided on the circumference of the second wheel shaft 170, and a lock groove 161 adapted to the protrusion 171 is provided on the second matching wheel 160. In the unlocked state, the projection surface of the protrusion 171 coincides with the lock groove 161. The second wheel shaft 170 of this embodiment is The direction of movement is almost consistent with the direction of movement of the push button 300. The linkage cooperation mode of the second password wheel 150 and the second matching wheel 160 is the same as the cooperation mode between the first password wheel 110 and the first matching wheel 120. No more details are given here. The lock tongue 320 is provided with a groove 322 for the reciprocating movement of the slider 321. When the password is correct, the protrusion 171 on the second wheel shaft 170 corresponds to the position of the lock groove 161.
