Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, how to implement the present invention is further explained below with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 8, the utility model provides a pair of automatic locking device 100 of sliding door, contain sliding door fixed lock seat 101, sliding door fixed lock ring 102 and automatic lock cam ear plate 103, wherein, sliding door fixed lock seat 101 one end fixed mounting is on sliding door stand 300, the other end is articulating automatic lock cam ear plate 103 through automatic lock hinge pin 104, sliding door fixed lock ring 102 one end fixed mounting is on sliding door 200 side frame, the other end cooperatees with the lock ring slide 105 of seting up on sliding door fixed lock seat 101, and be used for realizing the automatic locking or the autosegregation with sliding door fixed lock seat 101 under the effect of automatic lock cam ear plate 103, thereby realize the locking or opening of sliding door 200.

Specifically, as a preferred example of the present invention: the shackle slideway 105 is a U-shaped slideway structure with one end open and the other end closed, and the open end of the U-shaped slideway structure is arranged towards the end of the sliding door fixing lock seat 101 far away from the sliding door upright 300, and the closed end is arranged towards the end of the sliding door fixing lock seat 101 close to the sliding door upright 300. More specifically, in the preferred embodiment, a transition slope section 106 for facilitating the sliding in and out of the sliding door lock ring 102 is further provided at the lower side of the open end of the U-shaped chute structure, and the transition slope section 106 is in smooth transition connection with the lower side of the open end of the U-shaped chute structure.

Specifically, as a preferred example of the present invention: the sliding door fixing lock ring 102 is a U-shaped lock ring structure with one end open and the other end closed, the closed end of the U-shaped lock ring structure is fixedly welded on the side frame of the sliding door 200, and the open end is freely suspended at the side of the sliding door 200 and used for realizing automatic locking or automatic separation with the sliding door fixing lock seat 101 under the action of the automatic locking cam lug plate 103.

When the automatic sliding door locking device 100 is used for automatic sliding door 200 locking operation, the operation process is as follows: referring to fig. 5 to 8, the sliding door 200 is manually pulled toward the side close to the sliding door pillar 300, the sliding door fixing lock ring 102 impacts the automatic lock cam ear plate 103 on the sliding door fixing lock seat 101, so that the sliding door fixing lock ring 102 enters the inner side (i.e. the inside of the lock ring slide way 105 of the sliding door fixing lock seat 101) from the outer side (i.e. the outside of the lock ring slide way 105 of the sliding door fixing lock seat 101) of the automatic lock cam ear plate 103, when the sliding door fixing lock ring 102 enters the inner side (i.e. the inside of the lock ring slide way 105 of the sliding door fixing lock seat 101), the automatic lock cam ear plate 103 automatically falls down under the self-weight action and slides the sliding door fixing lock ring 102, so that the sliding door fixing lock ring 102 is locked by the automatic lock cam ear plate 103, and cannot retreat, thereby realizing the automatic locking of the sliding door 200, when the sliding door 200 needs to be opened, the automatic lock ear plate 103 is manually lifted, and then the sliding door 200 is manually pulled toward the side far from the sliding door pillar 300, so that the automatic lock ring 102 can move from the outer side (i.e. the inside of the sliding door fixing lock cam slide way 105), thereby realizing the automatic lock ring 105 of the sliding door fixing lock ring 101, namely, the sliding door fixing lock ring 1055. When the auto-lock cam lug 103 moves out of the lock ring slide way 105 of the sliding door fixing lock seat 101, the auto-lock cam lug 103 automatically falls down under its own weight, as shown in fig. 3 and 4.
