[0029] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0030] The utility model provides an oven door opening and closing mechanism and a locking mechanism, including an opening and closing mechanism for swinging an oven door 10 up and down and a locking mechanism for locking the oven door 10 to close the oven cavity. The opening and closing mechanism includes a first cylinder 100, and the front end of the first cylinder 100 is provided with a first piston rod 110 that can be telescopically moved forward and backward; the front end of the first piston rod 110 is movably connected to the inner end of a first connecting rod 120, the middle part of the first connecting rod 120 is fixedly arranged to form a first fulcrum, and the outer end of the first connecting rod 120 is connected to the side of the oven door 10;

[0031] When the first cylinder 100 drives the first piston rod 110 to telescopically move, the inner end and the outer end of the first connecting rod 120 swing up and down respectively relative to the first fulcrum, driving the oven door 10 to swing toward or away from the oven cavity;

[0032] Locking seats 310 are fixedly provided on both sides of the oven door 10, and a protruding engaging head 311 is provided on the locking seat 310. The locking mechanism includes a second cylinder 200, and the front end of the second cylinder 200 is provided with a second piston rod 210 that can be telescopically moved forward and backward. The second piston rod 210 is connected to a longitudinally movable locking hook 260 through a second connecting rod 220; a curved hook handle 270 extends outward from the outer end of the locking hook 260, and the hook handle 270 and the locking hook 260 are enclosed to form an engaging area, and an inclined wall 271 for guiding the engaging head 311 to move inward is formed on the hook handle 270;

[0033] When the oven door 10 is sealed on the oven cavity by the door opening and closing mechanism, the locking head 311 is located just above or just below the hook handle 270, and the second cylinder 200 drives the second piston rod 210 to move, so that the outer end of the second connecting rod 220 drives the locking hook 260 to move longitudinally toward the locking head 311; when the inclined wall 271 of the hook handle 270 abuts against the locking head 311, the locking hook 260 continues to move, and under the pressure of the hook handle 270, the locking head 311 moves inward along the extension direction of the inclined wall 271, driving the oven door 10 to move toward the oven cavity, until the locking head 311 is engaged in the locking area, and the oven door 10 locks and closes the oven cavity.

[0034] The above-mentioned oven door opening and closing mechanism and locking mechanism, through the design of the first fulcrum, uses the first cylinder 100 to drive the first piston rod 110 to adjust the position of the inner end of the first connecting rod 120, so that the outer end of the first connecting rod 120 swings up and down with the first fulcrum, drives the oven door 10 to swing toward or away from the oven cavity, and realizes the opening and closing of the oven door 10. Then, after the oven door 10 is sealed on the oven cavity by the door opening and closing mechanism, the oven door 10 is further moved toward the oven cavity for a distance to be locked by the design of the locking mechanism, and the engaging head 311 fixed on the oven door 10 is embedded in the engaging area, and the engaging head 311 is restricted from moving outward to ensure that the oven door 10 is fixed. When the oven door 10 needs to be opened, the engaging head 311 is separated from the engaging area by moving the second piston rod 210, and then the oven door 10 is swung by the door opening and closing mechanism to open the oven cavity. In this way, the oven door 10 is automatically opened and closed and locked by the door opening and closing mechanism and the drying efficiency and safety performance are improved.

[0035] The door opening and closing mechanism includes a mounting plate 130 mounted on the side of the oven, a first mounting seat 131 is provided on the mounting plate 130, and the middle part of the first connecting rod 120 is connected to the first mounting seat 131 to form a first fulcrum. In this way, by mounting the plate 130 on the side of the oven and the first mounting seat 131 on the mounting plate 130, the mounting seat is connected to the middle part of the first connecting rod 120 to form a structure similar to a "seesaw", so that the inner and outer ends of the first connecting rod 120 can swing up and down relative to the first fulcrum that is fixedly arranged.

[0036] The mounting plate 130 is provided with a second mounting seat 132, the first mounting seat 131 and the second mounting seat 132 are longitudinally aligned, the second mounting seat 132 is connected with a third connecting rod 140, the inner end of the third connecting rod 140 is connected to the second mounting seat 132 to form a third fulcrum, the outer end of the third connecting rod 140 is connected to the side of the oven door 10, and the first fulcrum and the third fulcrum are longitudinally aligned;

[0037] During the swinging of the first connecting rod 120, driven by the oven door 10, the outer end of the third connecting rod 140 swings relative to the third fulcrum, and the third connecting rod 140 is arranged in the same direction as the first connecting rod 120. In this way, the design of the third connecting rod 140 strengthens the connection between the oven door 10 and the mounting plate 130, and reduces the pressure on the first connecting rod 120.

[0038] Specifically, the front end of the first piston rod 110 is hinged to the inner end of the first connecting rod 120. In this way, when the first piston rod 110 is extended or retracted, the inner end of the first connecting rod 120 can be quickly rotated up and down through the hinged design, so that the outer end of the first piston rod 110 can swing greatly.

[0039] Specifically, the front end of the second piston rod 210 is hinged to the inner end of the second connecting rod 220. In this way, when the second piston rod 210 is extended or retracted, the inner end of the second connecting rod 220 can be quickly rotated up and down through the hinged design, so that the outer end of the second piston rod 210 can swing greatly.

[0040] The locking mechanism includes a fixing seat 230 fixed to the side of the oven, and the middle part of the second connecting rod 220 is connected to the fixing seat 230 to form a second fulcrum;

[0041] When the second piston rod 210 moves telescopically, the inner end and the outer end of the second connecting rod 220 swing up and down respectively relative to the second fulcrum. In this way, a structure similar to a "seesaw" is formed, and the outer end of the second piston rod 210 swings up and down by changing the upper and lower positions of the inner end of the second connecting rod 220.

[0042] A strip groove 221 is formed in the middle of the second connecting rod 220, and the strip groove 221 is arranged along the length direction of the second connecting rod 220. The fixing seat 230 has a protruding fixing head 231, and the middle of the fixing head 231 passes through the strip groove 221. The strip groove 221 is sleeved on the fixing head 231 to form a second fulcrum. In this way, through the design that the fixing head 231 passes through the strip groove 221, it can be realized that during the swinging process of the second connecting rod 220, the second connecting rod 220 is allowed to have a certain displacement as a whole, so as to meet the requirement that the hook lock maintains the vertical movement.

[0043] The outer end of the second connecting rod 220 is hinged on the middle part of the longitudinal rod 240. A locking hook 260 is provided on the end of the longitudinal rod 240. The middle part of the longitudinal rod 240 passes through a plurality of guide tracks of a fixedly arranged guide body 250. The guide body 250 is provided with a guide track that passes through the guide body 250 up and down. The longitudinal rod 240 moves up and down along the extension direction of the guide track.

[0044] When the second piston rod 210 telescopes, the outer end of the second connecting rod 220 swings up and down relative to the second fulcrum, driving the longitudinal rod 240 to move up and down along the extension direction of the guide track. In this way, the design of the guide body 250 can limit the movement deviation of the longitudinal rod 240, ensuring that the movement direction of the longitudinal rod 240 is vertical, and the design of the strip groove 221 and the fixed head 231 can realize that the second connecting rod 220 can be displaced as a whole to meet the vertical movement of the longitudinal rod 240.

[0045] Specifically, the first cylinder 100 and the first piston rod 110 and the second cylinder 200 and the second piston rod 210 are arranged in an inclined manner.

[0046] Specifically, the door opening and closing mechanism includes a plurality of connection seats 320 arranged on both sides of the oven door 10, and the outer ends of the first connection rod 120 and the outer ends of the third connection rod 140 are respectively connected to the plurality of connection seats 320. In this way, the oven door 10 is connected to the first connection rod 120 and the third connection rod 140.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
