Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-6, the embodiment of the present invention provides a chassis, including: the drawer locking device comprises a box body 8, a drawer 6 arranged on the box body 8 in a drawing mode, a locking piece fixed on the box body 8, a locking hook 4 movably arranged on the drawer 6, a handle 2 rotatably arranged on the drawer 6, and an elastic part 5, wherein two ends of the elastic part are respectively connected with the drawer 6 and the locking hook 4 and can deform along the moving direction of the locking hook 4.

In the case, in the process of closing the drawer 6, the locking piece is in contact with the locking hook 4 and enables the locking hook 4 to move on the drawer 6 in the forward direction until the locking piece is separated from the locking hook 4, and the locking hook 4 moves in the reverse direction under the restoring force action of the elastic component 5 until the locking piece is locked to lock the drawer 6. It should be noted that the forward movement direction and the reverse movement direction of the latch hook 4 are opposite. In practical application, the forward moving direction and the reverse moving direction of the locking hook 4 can be exchanged.

It can be understood that, because latch hook 4 sets up on drawer 6, the latch fitting is fixed on box 8, then at the in-process of closing the drawer, latch hook 4 is close to the latch fitting, continue to close drawer 6 after latch hook 4 contacts with the latch fitting, because the latch fitting is fixed on box 8, the latch fitting can promote latch hook 4 forward movement on drawer 6 until latch hook 4 separates with the latch fitting, continue to close drawer 6, elastic component 5 takes place deformation when the latch fitting moves on drawer 6, then latch hook 4 backward movement on drawer 6 under elastic component 5's restoring force effect after latch hook 4 separates with the latch fitting, latch fitting 4 pins the latch fitting, drawer 6 closes simultaneously, the purpose of locking drawer 6 has been reached. In the case, during the process of pressing the handle 2 on the closed drawer 6, the handle 2 rotates to push the latch hook 4 to move forward on the drawer 6 until the latch hook 4 releases the latch to unlock the drawer 6.

It can be understood that, when drawer 6 needs to be opened, drawer 6 is unlocked earlier, specifically, handle 2 on the closed drawer 6 is pressed, and in the pressing process, handle 2 rotates, and handle 2 contacts with latch hook 4 after handle 2 rotates to the settlement angle, continues to rotate handle 2 and makes handle 2 promote latch hook 4 forward movement on drawer 6 until latch hook 4 releases the latch fitting, reaches the purpose of unlocking drawer 6, can pull out drawer 6 after drawer 6 unblocks.

In the practical application process, the set angle and the rotating angle of the handle 2 when the locking element is released by the locking hook 4 are selected according to the practical requirement. Preferably, the angle of rotation of the handle 2 when the shackle 4 releases the lock is 90 °, and the set angle is less than 90 °. According to the case provided by the embodiment, automatic locking can be achieved by closing the drawer 6, and unlocking can be achieved by pressing the handle 2, so that the drawer 6 can be locked and unlocked.
