Example 2

Embodiment 2 is a preferable improvement of embodiment 1, and the slider returning mechanism 50 may include: the mounting seat 51 is fixedly arranged on the top side of the support frame 10; a support shaft 52 fixed on the mounting base 51; the baffle plate 53 is sleeved on the outer side of the support shaft 52 and is fixed in position; a spring 54 sleeved outside the support shaft 52 and fixed on one side of the baffle plate 53; an adjusting plate 55 is slidably provided on the support shaft 52, and is provided with one side contacting the spring 54 and the other side contacting the front door slider 30.

The operating principle of the slide return mechanism 50 is as follows:

when the first button 21 is pressed, the pull piece sliding block 20 slides and further acts on limiting blocks (see a front view part in fig. 3 and not shown) on two sides of the front door sliding block 30 to drive the front door sliding block 30 to slide, the front door sliding block 30 acts on the adjusting plate 55 and the spring 54, the spring 54 is compressed, the first button 21 is released, the spring 54 restores elastic deformation, the front door sliding block 30 returns to the initial position, and the pull piece sliding block 20 is driven to return to the initial position due to the action of the limiting blocks;

when the second button 31 is pressed, the front door slider 30 slides, the front door slider 30 acts on the adjusting plate 55 and the spring 54, the spring 54 is compressed, the second button 31 is released, the spring 54 restores the elastic deformation, and the front door slider 30 returns to the initial position.

Wherein, the front door sliding block 30 is a single plate structure, and two sides are provided with limiting blocks.

Wherein, pulling-on piece slider 20 is including perpendicular first board, second board and third board in proper order, and first board and third board are contradicted the setting respectively on the stopper.

This embodiment 2 solves how to restore the adjacent two sliders to the original positions by the slider restoring mechanism 50.

Example 3

Embodiment 3 is a preferable improvement of embodiment 1, and the latch mechanism 40 may include: the connecting plate 43 is arranged at the bottom side of the support frame 10, penetrates through the support frame 10 and is fixedly connected with the front door sliding block 30, and the bottom side of the connecting plate is provided with an oblique structure 44; the adjusting block 45 is fixed on the lower shell 60 through a rotating shaft 46, one side of the adjusting block is provided with a sliding column 47, the other side of the adjusting block is provided with a protrusion 41, the sliding column 47 is connected with the oblique structure 44 in a sliding mode, and the protrusion 41 is matched with the lock hook 42 in a clamping mode;

the latch mechanism 40 operates as follows:

the second button 31 is pressed to drive the front door slider 30 to horizontally slide, the front door slider 30 is driven to horizontally move due to the fixed connection between the front door slider 30 and the front door slider 30, the sliding column 47 of the adjusting block 45 does not horizontally move, so that the sliding column 47 can slide downwards along the highest point of the inclined structure 44, the adjusting block 45 is fixed on the lower shell 60 by the rotating shaft 46, one side of the adjusting block 45 moves downwards, the side close to the protrusion 41 moves upwards, the protrusion 41 is separated from the lock hook 42, and the front door 101 of the luggage case is opened.

When the second button 31 is released, the front door slider 30 returns to the initial position, and because the side of the sliding column 47 of the adjusting block 45 is lighter and the side of the protrusion 41 is heavier, the sliding column 47 returns to the highest point of the inclined structure 44, the protrusion 41 moves downwards to be separated from the lock hook 42, and the front door 101 of the luggage case is closed.

The embodiment 3 solves the problem of how to lock the protrusion 41 and the locking hook 42.

Example 4

Embodiment 4 is a preferred refinement of embodiment 1, and the spacing between the bottom plane of the first button 21 and the pull-tab slider 20 may be smaller than the spacing between the second button 31 and the front door slider 30, such that: pressing the first button 21 opens the two snap tabs 22 and moves the protrusion 41 upward but the protrusion 41 does not disengage from the catch 42.

Embodiment 4 avoids the problem that when the first button 21 is pressed, the two sliders slide simultaneously, and the front door 101 of the luggage case and the zipper main bag 100 are opened simultaneously, by setting the stroke difference between the first button 21 and the second button 31.

Example 5

Example 5 is a preferred refinement of example 1, the latch may further comprise: one side of the fastening seat 23, which is far away from the pull piece slider 20, is fixed with one of the fastening pieces 22, the other side is connected with the other fastening piece 22 in a sliding manner, and the other fastening piece 22 is fixed with the pull piece slider 20.

One of the fastener pieces 22 is slidably disposed in the fastener seat 23, so that the fastener piece 22 can be ensured to be stable in sliding without deflection, the fastener piece 22 is not deformed, and the zipper cannot be fastened.

Example 6

Example 6 is a preferred refinement of example 1, the latch may further comprise: a lower housing 60, on which the support frame 10 is mounted; and an upper housing 61 disposed on the top side of the lower housing 60 for clamping the first button 21 and the second button 31.

Wherein, lower shell 60 has the support chamber, and the support chamber is used for erection bracing frame 10, still plays the effect of buckle seat 23, mount pad 51 on the fixed stay frame 10 simultaneously, and simultaneously, support chamber both sides and have the track for two sliders slide along the track, guarantee gliding stability. Drag the chamber middle part downside and place the chamber of accomodating of trip 42 and switch on, accomodate the chamber both sides and have the through-hole and be used for installing pivot 46.

A luggage case includes a latch as described above.

The working principle is as follows:

when the first button 21 is pressed, the first button 21 moves vertically, the pull piece slider 20 is driven to move to one side due to the fact that the bottom side inclined plane is in sliding connection with the pull piece slider 20, the buckling pieces 22 are driven to slide to one side, the two buckling pieces 22 are opened, the zipper main bag 100 is opened, the first button 21 is loosened, the spring 54 of the slider restoring mechanism 50 restores elastic deformation, the front door slider 30 returns to the initial position, the pull piece slider 20 is driven to return to the initial position due to the effect of the limiting block, and the two buckling pieces 22 are closed.

When the second button 31 is pressed, the second button 31 moves vertically, and the inclined plane at the bottom side is connected with the front door sliding block 30 in a sliding manner, so that the front door sliding block 30 is driven to move to one side, the bulge 41 of the clamping mechanism 40 is driven to move upwards, the lock hook 42 is separated from the bulge 41, the front door 101 of the luggage case is opened, the second button 31 is released, the spring 54 of the sliding block return mechanism 50 recovers elastic deformation, the front door sliding block 30 returns to the initial position, the bulge 41 of the clamping mechanism 40 moves downwards, the lock hook 42 is locked with the bulge 41, and the front door 101 of the luggage case is closed.
