Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution: a quick-opening door structure for a washing machine device, including a connection bracket 2 provided on the front side of the door panel 1. A connection block 3 is fixedly provided on the connection bracket 2. A threaded hole is provided on the front side wall of the connection block 3. A screw rod 7 is threadedly connected in the threaded hole. A connection support 6 is fixedly provided on the door panel 1 at a position corresponding to the screw rod 7. The inner end of the screw rod 7 passes through the connection block 3 and is rotatably connected to the connection support 6;

[0020] The connection support 6 is a U-shaped plate-like structure with an opening facing the rear side. The inner end of the screw rod 7 passes through the front side plate of the connection support 6. Nuts 8 are provided at both the front and rear ends of the screw rod 7 on the front side plate of the connection support 6. A first pin hole is provided on each of the nuts 8. A second pin hole is provided on the screw rod 7 at a position corresponding to the first pin hole. The nut 8 is fixedly connected to the screw rod 7 by a split pin 72 passing through the first pin hole and the second pin hole; A handle 71 is fixedly provided at the outer end of the screw rod 7;

[0021] The right end of the connecting bracket 2 is provided with a horizontally arranged hinge plate 22. At the position corresponding to the hinge plate 22, there is a fixed seat 4. A groove is formed on the front side wall of the fixed seat 4. A vertically arranged pin shaft 41 is arranged in the groove of the fixed seat 4. The hinge plate 22 is located in the groove of the fixed seat 4 and is movably connected with the pin shaft 41. The left end of the connecting bracket 2 is provided with a horizontally arranged insertion plate 21. At the position corresponding to the insertion plate 21, there is a limit block 5. A limit groove 51 is formed on the top wall of the limit block 5. The insertion plate 21 is located in the limit groove 51, and the width of the limit groove 51 is greater than the width of the insertion plate 21. The connecting bracket 2 can rotate horizontally along the pin shaft 41 and move its insertion plate 21 along the width direction of the limit groove 51.

[0022] Working principle:

[0023] The fixed seat 4 and the limit block 5 are fixedly arranged on the equipment housing 100;

[0024] When it is necessary to open the door panel 1, rotate the handle 71 counterclockwise to make the connecting bracket 2 rotate horizontally towards the inside along the pin shaft 41, so that the insertion plate 21 moves towards the inside along the limit groove 51 until the rear side wall of the insertion plate 21 abuts against the rear side wall of the limit groove 51. Continue to rotate the handle 71 counterclockwise. Since the rear side wall of the insertion plate 21 abuts against the rear side wall of the limit groove 51, the connecting bracket 2 cannot continue to rotate towards the inside. Therefore, the screw rod 7 moves towards the outside by using the lead screw pair formed between the screw rod 7 and the connecting block 3. The screw rod 7 pulls the connecting support 6 and the door panel 1 towards the outside. When the door panel 1 moves towards the outside by a certain distance and a gap is generated at the doorway of the equipment housing 100, manually lift the connecting bracket 2 and the door panel 1 and move them along the axial direction of the pin shaft 41 until the insertion plate 21 is higher than the limit groove 51, then the door panel 1 can be pulled to rotate towards the outside along the pin shaft 41, completing the rapid opening of the door panel 1;

[0025] When it is necessary to close the door panel 1, manually lift the connecting bracket 2 and the door panel 1 again until the insertion plate 21 is higher than the limit groove 51. Then push the door panel 1 to make it rotate towards the inside along the pin shaft 41, so that the insertion plate 21 is re-embedded in the limit groove 51. Rotate the handle 71 clockwise to make the connecting bracket 2 rotate horizontally towards the outside along the pin shaft 41, so that the insertion plate 21 moves towards the outside along the limit groove 51 until the front side wall of the insertion plate 21 abuts against the front side wall of the limit groove 51. Continue to rotate the handle 71 clockwise. Since the front side wall of the insertion plate 21 abuts against the front side wall of the limit groove 51, the connecting bracket 2 cannot continue to rotate towards the outside. Therefore, the screw rod 7 moves towards the inside by using the lead screw pair formed between the screw rod 7 and the connecting block 3. The screw rod 7 pushes the connecting support 6 and the door panel 1 towards the inside, thus completing the closing of the door panel 1.

[0026] Further, a sealing gasket 9 is fixedly arranged on the inner side surface of the door panel 1 to improve the sealing performance between the door panel 1 and the doorway of the equipment housing 100.

[0027] The quick-opening structure of the washing machine device disclosed in this embodiment forms a lead screw pair between the lead screw 7 and the connecting bracket 2 through the threaded connection between the lead screw 7 and the connecting block 3, and uses the front and rear side walls of the limiting groove 51 as the limiting fulcrums for the front and rear displacement of the connecting bracket 2. Thus, by screwing the lead screw 7 and cooperating with lifting the connecting bracket 2, the quick opening and closing of the door panel 1 can be completed. The operation is convenient and efficient, and the opening and closing of the observation door can be easily achieved. Moreover, through the lead screw pair formed between the lead screw 7 and the connecting bracket 2 and the front and rear side walls of the limiting groove 51 as the limiting fulcrums for the front and rear displacement of the connecting bracket 2, the door panel 1 can be closely attached to the opening of the equipment housing 100, is not easy to loosen, and is combined with the sealing gasket 9 to make the sealing effect of the quick-opening structure better.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
