Referring to fig. 1 to 7, an embodiment of the present utility model provides a latch structure 1, which is mainly used in a drawer box 2, reduces operation steps of a user, and has a simple structure. The latch structure 1 includes a push lock body 10, and a plurality of locking bolts 12 disposed on the push lock body 10, where the plurality of locking bolts 12 need to be moved simultaneously to lock/unlock. A plurality of independent drawers 20 (only 2 are schematically shown) are provided in the drawer box 2, and each locking tongue 12 corresponds to a drawer 20 position. The latch structure 1 has a locked/unlocked position and the drawer 20 has a closed/pulled-out position; when the locking structure 1 is located at the locking position, the drawer 20 located at the closing position is locked with the corresponding lock tongue 12, and the drawer 20 located at the pulling-out position can be moved to the closing position to be locked with the corresponding lock tongue 12; when the latch structure 1 is in the unlocked position, all drawers 20 are unlocked from the corresponding locking tongues 12, and at this time, all drawers 20 can be pulled out and closed freely.

Specifically, the drawer box 2 includes a drawer box body 2a, a plurality of drawers 20 are vertically arranged in the drawer box body 2a, the drawer box body 2a has an opening 2b, and the drawers 20 can be pulled out from the opening 2b of the drawer box body 2 a.

Each drawer 20 is provided with a locking block 22 corresponding to the lock tongue 12, and the locking blocks 22 are matched with the lock tongue 12 and are used for preventing the drawer 20 from being pulled out from the opening 2b, so that the drawer 20 is locked. When the latch structure 1 is located at the locking position, the locking block 22 of the drawer 20 located at the pulling-out position can move to the closing position beyond the corresponding lock tongue 12 to be locked, and at this time, the locking block 22 is located at one side of the lock tongue 12 away from the opening 2b of the drawer box 2; in the process, the bolt 12 is located in the moving path of the lock block 22. When the latch structure 1 is in the unlocked position, the lock block 22 of the drawer 20 in the pulled-out position cannot be locked beyond the lock tongue 12; in this process, the locking bolt 12 is not located in the path of movement of the locking block 22. It should be noted that, when the latch tongue 12 is located on the moving path of the latch block 22, the latch tongue 12 is horizontally aligned with the latch block 22, and when the drawer 20 moves from the pulled-out position to the closed position, the latch block 22 may pass over the latch tongue 12; when the bolt 12 is not located on the moving path of the lock block 22, the bolt 12 is located above the lock block 22. In other embodiments, when the locking bolt 12 is not located in the moving path of the locking block 22, the locking bolt 12 may be located below the locking block 22, the locking bolt 12 may also be located in the front-to-rear horizontal direction of the locking block 22, and the locking block 22 may not always pass over the locking bolt 12.

Each locking block 22 encloses a locking groove 21 with the drawer body 23, the locking groove 21 being located on the side of the locking block 22 close to the opening 2 b. When the latch structure 1 is located at the locking position and the drawer 20 is located at the closing position, the lock tongue 12 is clamped in the corresponding locking groove 21 (as shown in fig. 2); when the latch structure 1 is in the locking position and the drawer 20 is in the pulled-out position, moving the drawer 20 to the closed position can make the locking block 22 pass over the lock tongue 12 so that the lock tongue 12 is blocked in the corresponding locking groove 21, and the drawer 20 is locked.

The drawer 20 has a drawer panel 20a and two drawer side panels 20b connected to both ends of the drawer panel 20a, a drawer back panel (not shown) disposed opposite the drawer panel 20a, and a drawer bottom panel (not shown) connected to bottoms of the drawer panel 20a, the drawer side panels 20b, and the drawer back panel. When the drawer 20 is in the closed position, the drawer panel 20a is exposed from the opening 2 b.

In this embodiment, the lock block 22 is disposed on one of the drawer side panels 20 b. Each locking block 22 and the drawer body 23 enclose a locking groove 21, and the locking groove 21 is located at one side of the locking block 22 near the drawer panel 20a (opening 2 b). When the locking structure 1 is positioned at the locking position and the drawer 20 is positioned at the closing position, the lock tongue 12 is clamped in the locking groove 21 corresponding to the drawer 20, so that the drawer 20 is prevented from shaking when locked; as shown in fig. 6, when the latch structure 1 is in the unlocked position, each of the locking bolts 12 is disengaged from the locking groove 21.

The drawer box 2 can lock/unlock a plurality of drawers 20 simultaneously by utilizing one locking structure 1, so that the operation steps of a user are reduced; further, when the latch structure 1 is located at the locking position, the drawer 20 located at the pulled-out position can be also individually closed and automatically locked by the latch structure 1, further reducing the operation steps of the user.

The pushing lock body 10 is forced to move back and forth to switch the locking position and the unlocking position of the locking structure 1. In this embodiment, the pushing lock body 10 moves back and forth up and down, and moving up the pushing lock body 10 can move the latch structure 1 to the unlocking position, the lock tongue 12 is located above the lock block 22 and not on the moving path of the lock block 22; moving the lock body 10 downward moves the latch structure 1 to the locked position, the lock tongue 12 is located on the moving path of the lock block 22, and the lock block 22 can be locked over the lock tongue 12. It should be noted that, in the process that the locking block 22 passes over the locking bolt 12 to lock, the locking block 22 pushes the corresponding locking bolt 12 to move to the unlocking position, and then the locking bolt 12 drives all the locking bolts 12 (i.e. pushes the locking body 10) to move to the unlocking position, and when the locking block 22 passes over the locking bolt 12, all the locking bolts 12 can move downwards to the locking position together to lock.

Further, a first chamfer 12a is provided on the chamfer surface of the lock tongue 12 near the opening 2b, and a pushing inclined surface 22a is provided on the lock block 22, when the latch structure 1 is located at the locking position, the pushing inclined surface 22a of the drawer 20 located at the pulling-out position pushes the first chamfer surface 12a and moves the pushing lock body 10 to move the lock block 22 to the closing position beyond the lock tongue 12 for locking.

The first chamfer 12a is provided on the tongue 12 not only in a direction opposite to the closing direction of the drawer 20, but also in a direction such that the linear movement of the abutment inclined surface 22a pushes the movement of the tongue 12 in the vertical direction; in this embodiment, the first chamfer 12a is located on the beveled side of the tongue 12 near the opening 2b, which substantially coincides with the edge at this location. When the latch structure 1 is at the locking position, in the process of moving the drawer 20 from the pulling-out position to the closing position, the pushing inclined surface 22a pushes the first inclined surface 12a to move the latch tongue 12 upwards and drive the pushing latch body 10 to move upwards, the locking block 22 passes through the latch tongue 12 to enable the latch tongue 12 to correspond to the position of the locking groove 21, and the latch tongue 12 falls into the locking groove 21 to lock the drawer 20.

Further, a second straight surface 12d is arranged on one side surface of the lock tongue 12 far away from the opening 2b, and a third straight surface 22b is arranged on one side surface of the lock block 22 near the opening 2b; when the latch structure 1 is in the locking position, the lock block 22 of the drawer 20 in the closed position presses the second straight surface 12d of the latch tongue 12 toward the opening 2b, and the second straight surface 2d interferes with the third straight surface 22b to lock the drawer 20.

Further, the latch structure 1 further comprises a first elastic member 13, and the first elastic member 13 automatically maintains the latch structure 1 in the locked position. Specifically, the first elastic member 13 is a spring, two ends of which are respectively fixed to the drawer box main body 2a and the push lock main body 10, and when the latch structure 1 moves up to the unlocking position against the elastic force of the first elastic member 13, each drawer 20 can move to the pulled-out position, and when the force applied to the latch structure 1 is released, the push lock main body 10 automatically moves down under the resilience of the first elastic member 13 to return the latch structure 1 to the locking position.

In this embodiment, the latch structure 1 further includes a plurality of second elastic members 14, one end of the second elastic members 14 is fixed on the push lock body 10, the lock tongue 12 is connected to the other end of the second elastic members 14, and the second elastic members 14 are, for example, elastic sheets. The lock tongue 12 protrudes outwards relative to the surface of the lock pushing body 10, the lock pushing body 10 is provided with a lock tongue accommodating groove 101, when the lock tongue 12 is pushed by external force, the second elastic piece 14 (elastic piece) bends inwards, and the lock tongue 12 can be pressed into the lock tongue accommodating groove 101. When the latch structure 1 is provided with the second elastic member 14, the latch structure 1 can be directly pushed into the mounting groove from the mounting hole on the drawer box body 2a for mounting, and the mounting method is relatively simple. On the basis, a first straight surface 12c is arranged on the same side of the lock tongue 12 as the first inclined surface 12a, and the first straight surface 12c is opposite to the second straight surface 12 d; when the latch structure 1 is in the locking position, the locking block 22 of the drawer 20 in the closed position pushes the second straight surface 12d to move toward the opening direction toward the drawer panel 20a (opening 2 b), and at this time, the first straight surface 12c interferes with the push lock body 10, so that the latch 12 cannot be displaced toward the latch receiving groove 101, and the drawer 20 cannot be locked and opened.

Further, a second chamfer 12b is provided on a side of the lock tongue 12 facing the installation direction of the latch structure 1, when the latch structure 1 is installed, the lock tongue 12 is pressed into the lock tongue accommodating groove 101 by the second chamfer 12b and the drawer box body 2a, and after the latch structure 1 is installed in place, the lock tongue 12 automatically pops out. In this embodiment, the latch structure 1 is installed in the installation hole from bottom to top, and then the second chamfer 12b is disposed on the upper surface of the latch tongue 12.

In other embodiments, the locking bolt 12 may be fixedly disposed directly on the push lock body 10 and protrude outward from the surface of the push lock body 10, for example: the locking tongue 12 may be integrally formed with the push lock body 10. When the latch 12 is fixedly installed, the second elastic member 14, the second chamfer 12b, and the first straight surface 12c may not be installed on the latch 12.
