The switch 23 can be disposed on one side of the sliding portion 21 opposite to the clamping structure 22, the switch 23 extends from the sliding portion 21 to the outer side of the door 10 and protrudes out of the outer side of the door 10, and then the user can control the sliding portion 21 by pushing the switch 23, so that the user can more conveniently push the sliding portion 21 to slide between the first position a and the second position B, and the clamping structure 22 is clamped and matched with the limiting portion 201.

The switch member 23 may be provided in a plate-shaped structure, and a pushing surface thereof contacting with the hand may be provided in an arc-shaped surface, so that the user is more comfortable when pushing the switch member 23. In some embodiments, a frosted surface may be further disposed on the pushing surface to enhance friction and prevent the user's hand from slipping off the operating surface when pushing the switch member 23. The switch 23, the retaining structure 22 and the sliding portion 21 can be integrally formed to make the connection between the switch 23 and the sliding portion more firm, so as to avoid damage when the switch 23 is pushed and when the retaining structure 22 is retained by the limiting portion 201.

As shown in fig. 5, when the door 10 is closed relative to the cabinet 200, the switch 23 can be pushed to slide the sliding portion 21 to the first position a, and the holding structure 22 slides synchronously with the sliding portion 21, so that the holding structure 22 can be held at the position-limiting portion 201. At this time, when the user pulls the door body 10 outward, the door body 10 can be opened, but a large noise is generated to affect the work or rest of other persons.

As shown in fig. 6, after cooking, when the user wants to open the box 200, the user can push the switch 23 to slide the sliding portion 21 to the second position B, the holding structure 22 will also slide synchronously with the sliding portion 21, and the holding structure 22 can be separated from the limiting portion 201. At this moment, the user pulls the door body 10 and can open the box 200, and through the slip that pushes away switch member 23 control sliding part 21, can avoid the door body 10 to hold the structure 22 and produce great sound in the collision between the spacing portion 201 at the in-process of opening and close, and then reduce the produced noise in the use effectively, promote user's use and experience.

In some embodiments, the latch 20 can slide in the vertical direction relative to the door 10, and the first position a is located below the second position B. Thus, the sliding portion 21 can slide relative to the door 10 more smoothly, so as to better drive the clamping structure 22 and the limiting portion 201 to be clamped and matched. Correspondingly, the limiting portion 201 can be disposed to be inclined upward, and when the sliding portion 21 drives the retaining structure 22 to slide downward, the limiting portion 201 can be better engaged with the retaining structure 22.

Referring to fig. 5 and 6, in some embodiments, the door structure 100 further includes a reset piece 50, the reset piece 50 connects the door 10 and the sliding portion 21, and the reset piece 50 is configured to provide a force to the sliding portion 21 to move from the second position B to the first position a.

So, the piece that resets 50 has the pulling force to first position A direction to sliding part 21, when there is not external force to promote sliding part 21, sliding part 21 can remain throughout in first position A department, and then the door body 10 is when the closure card structure 22 can be better with spacing portion 201 joint cooperation, further avoid the door body 10 to be directly pulled open, reinforcing security.

Specifically, the restoring member 50 may be a spring, an elastic cord, or the like. One end of the reset piece 50 is connected to the sliding portion 21, and the other end is fixed to the door body 10, and the reset piece 50 always has a certain pulling force on the sliding portion 21, so that the sliding portion 21 can always be kept at the first position a when no external force is pushed.

When the door 10 needs to be opened, the user needs to push the switch 23 to overcome the elastic force of the reset piece 50, so that the sliding part 21 slides to the second position B and then pulls the door 10, and after the door 10 is opened and the external force is removed, the sliding part 21 slides back to the first position a under the pulling force of the reset piece 50.

When the door body 10 needs to be closed, the user needs to push the switch piece 23 to overcome the elastic force of the reset piece 50 to slide the sliding portion 21 to the second position B and then push the door body 10, after the external force is removed, the reset piece 50 can pull the sliding portion 21 to slide to the first position a, and the switch piece 23 does not need to be pushed again to slide the sliding portion 21 to the second position B. The sliding portion 21 can be maintained at the first position a by the pulling force of the restoring member 50.

It should be noted that, when the sliding portion 21 is located at the first position a, the retaining structure 22 can be directly separated from the limiting portion 201 under the action of an external force, that is, the door body 10 can be pulled away under the action of the external force. However, after the retaining structure 22 is pushed upwards by the limiting portion 201, the sliding portion 21 of the reset element 50 will immediately return to the first position a, so that the sliding portion collides with the door 10 easily to generate noise, and further the acting force of the reset element 50 is actively overcome when the door is opened, so that the generation of large noise in the door opening process can be avoided.

In some embodiments, an end of the catch structure 22 opposite to the sliding portion 21 may be formed with a guide surface, which is obliquely disposed for guiding the stopper portion 201 to slide toward the catch structure 22 when the door body 10 is closed. Thus, when the user closes the door 10, the user can directly push the door 10 to close, the guide surface can guide the limiting portion 201 to directly slide to the limiting position of the clamping structure 22, and the sliding portion 21 can pull the sliding portion 21 to slide back to the first position a under the pulling force of the reset piece 50 so that the door 10 is relatively closed.

Certainly, in the mode that the user directly promoted the door body 10 closure and directly pulled open the door body 10, because joint piece 20 does not have external force to support, joint piece 20 can collide and produce the sound with the door body 10 under the effect that resets 50, and then avoids directly promoting the door body 10 and closes the door or directly pulls open the door body 10 when the quiet condition of needs to avoid producing the influence to other people.

In some embodiments, the switch member 23, the sliding portion 21 and the retaining structure 22 may be provided as an integral structure by injection molding or other means. So, the connection between the three is more firm in order can be better cooperation, avoids promoting the in-process fracture damage, increase of service life.
