The stop pin can slide in the main line part 11 of the chute and is stopped after falling into the bent part 12.
The sliding plate is provided with an arc-shaped open slot 14 on the left side, which is sleeved on the stop pin.
The pulling plate 1 can slide in a slideway above the sliding plate, and the left end of the pulling plate is provided with a push-pull notch.
The push-pull notch comprises an inlet 15 and a push-pull opening 16, the inlet is communicated with the push-pull opening, and the push-pull opening is an arc opening which is bent forwards.
The diapire of import is the horizontal wall, and the roof of import is the inclined wall, and the structure of import makes can be better cup joint with the stop pin.
The push-pull notch can be sleeved in the stop pin 13 and drives the stop pin to slide in the sliding groove.
The utility model provides a push-and-pull door is from return means's approximate theory of operation does:
initially, the fixed plate and the sliding plate 2 are in a closed state, as shown in fig. 1, and the push-pull opening of the pull rod is sleeved on the stop pin; the pull rod 1 moves outwards (enlarging to the push-pull door body means pulling the push-pull door body to open), as shown in fig. 6, the pull rod pulls the stop pin 13 to move through the left wall of the push-pull opening 16, so that the sliding plate is driven to move, when the stop pin falls into the bending part 12, the stop pin 13 can slide out of the push-pull opening 16 to the inlet 15, and simultaneously the stop pin slides into the lower part of the open slot 14, as shown in fig. 2, as the stop pin falls into the bending part to stop, the sliding plate cannot return under the action of the stop pin, as shown in fig. 7, the pull rod is separated from the stop pin by moving outwards, and the pull rod can continue to move outwards (enlarging to the push-pull door body means separating the push-pull door body from the self-return structure, but the door body is not influenced);
when the pull rod moves inwards (the condition that the pull rod is amplified on the push-pull door body means that the push-pull door body is pulled to be closed), an inlet of the push-pull notch contacts with the stop pin firstly, along with the movement of the pull rod, the stop pin enters the push-pull opening 16 along the inlet 15, meanwhile, because the push-pull opening 16 is an arc opening which is bent forwards, the stop pin can move forwards in the bent part so as to be separated from the bent part, and the stop pin moves to the middle part of the open slot 14.
Example 2
With reference to fig. 9 and 10, a refrigerator with a sliding door self-return device as described in embodiment 1 is provided.
Specifically, the freezer includes door frame 17, and sliding connection has two push-and-pull door bodies 18 on the door frame, and two self return structures are installed on the upper portion of door frame, and the top installation arm-tie of the push-and-pull door body.
Each sliding door body is provided with a set of sliding door self-return device, taking the sliding door body on the right side as an example, the sliding door body on the left side moves to open and move to the right side to close the sliding door body, the pulling plate is arranged in the center of the top of the sliding door body on the right side, and the self-return structure is correspondingly arranged on the top of the door frame. Referring to fig. 9 and 10, the fixing plate of the self-return structure is mounted on the door frame in an inverted manner.
The working principle of the self-return device is explained by taking the sliding door body on the right side as an example:
initially, the push-pull door body is closed, when the push-pull door body needs to be opened, the push-pull door body is pulled leftwards, the pull rod on the push-pull door body moves leftwards, the pull rod pulls the stop pin 13 to move through the push-pull opening 16 at the moment, so that the sliding plate is driven to move, when the stop pin falls into the bending part 12, the stop pin 13 can slide out of the push-pull opening 16 to the inlet 15, meanwhile, the stop pin slides into the lower part of the open slot 14, the stop pin falls into the bending part for stopping, the sliding plate cannot return under the action of the stop pin, the push-pull door body is pulled outwards, the pull rod on the push-pull door body is separated from the stop pin, the push-pull door body can continue to move leftwards until the push-pull door body is completely opened, and the movement of the push-pull door body is not affected;
when the push-pull door body needs to be closed, the push-pull door body is moved rightwards, the first half of the process needs to be manually pulled by a user, an inlet of a push-pull notch of a pull rod on the push-pull door body contacts with a stop pin firstly, along with the movement of the pull rod, the stop pin enters a push-pull opening 16 along an inlet 15, meanwhile, the push-pull opening 16 is an arc opening which is bent forwards, the stop pin can move forwards in a bent part and then is separated from the bent part, the stop pin moves to the middle part of an open slot 14, at the moment, the push-pull door body does not need to apply external force, the stop pin is separated from the bent part, the sliding plate can be pulled to move and close under the action of the tensile force of a telescopic spring, the sliding plate drives the pull rod and the push-pull door body to move through the stop pin, when the sliding and closing is performed, the closing process is slow until the push-pull door body is closed tightly.
The utility model provides a from return means makes the sliding door body also can automatic closure when half back does not have external force, has solved the easy closed not tight problem of half back of the sliding door body among the prior art.
