[0030] The present utility model provides a double-door linkage structure 10, which is applied to an electric oven 100. In addition, the present utility model is also applicable to other electrical appliances that require bilateral opening.

[0031] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0032] In an embodiment of the present utility model, as Figures 1 to 4 shown, the double-door linkage structure 10 includes a housing assembly 11, a left door body 12, a right door body 13 and a linkage assembly 14. The housing assembly 11 has a receiving cavity and a front-side opening communicating with the receiving cavity; the left door body 12 and the right door body 13 are rotatably provided on the front side of the housing assembly 11; the linkage assembly 14 is provided on the top of the housing assembly 11. The linkage assembly 14 includes a sliding member 141 and a driving member 142. The sliding member 141 can slide back and forth; there are two driving members 142. One ends of the two driving members 142 are symmetrically hinged to both ends of the sliding member 141 respectively, and the other ends of the two driving members 142 are respectively hinged to the left door body 12 and the right door body 13; the sliding member 141 slides back and forth to drive the two driving members 142 to swing in opposite directions, thereby driving the left door body 12 and the right door body 13 to open or close the front-side opening simultaneously.

[0033] It can be understood that the left door body 12 and the right door body 13 are rotationally fitted with the housing assembly 11 through a rotating shaft or a hinge. The present utility model uses a rotating shaft to achieve rotation. The left door body 12 and the right door body 13 are provided with door clips at positions close to the front-side opening. The driving member 142 drives the left door body 12 and the right door body 13 to rotate by pushing the door clips. The left door body 12 and the right door body 13 of the present utility model are rotated simultaneously through the linkage assembly 14, that is, opened or closed simultaneously. The sliding member 141 of the linkage assembly 14 slides back and forth to drive the two driving members 142 to swing in opposite directions, and the two driving members 142 respectively drive the left door body 12 and the right door body 13 to rotate in opposite directions. When the two door bodies rotate simultaneously in the direction close to the front-side opening, the front-side opening is closed. When the two door bodies rotate simultaneously in the direction away from the front-side opening, the front-side opening is opened. Due to the linkage relationship between the left door body 12 and the right door body 13, when using, only one of the door bodies needs to be rotated, and the other one will also perform synchronous actions, which is convenient for the operator to open and close.

[0034] The technical solution of the present utility model includes a housing assembly 11, a left door body 12, a right door body 13 and a linkage assembly 14. The linkage assembly 14 includes a sliding member 141 and two driving members 142. The sliding member 141 slides back and forth to drive the two driving members 142 to swing in opposite directions, thereby driving the left door body 12 and the right door body 13 to open or close the front-side opening simultaneously. Due to the technical means of using the sliding link structure of the linkage assembly 14 to achieve the simultaneous opening and closing of the two door bodies, the technical problem in the prior art that a single-side door opening occupies a large space and a double-side door opening is inconvenient is effectively solved, and the technical effect of saving operation space and being convenient for opening and closing the door is achieved.

[0035] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the sliding member 141 is T-shaped. The sliding member 141 includes a sliding portion 1411 and a hinged portion 1412 that are vertically connected. The sliding portion 1411 is disposed on the top of the housing assembly 11 so as to be movable back and forth. The two driving members 142 are respectively hingedly connected to both ends of the hinged portion 1412. The sliding member 141 of the present utility model is a flat plate structure formed by integral stamping. First hinge holes are respectively provided at both ends of the hinged portion 1412, and a second hinge hole is provided on the driving member 142. Rotational cooperation is achieved between the first hinge hole and the second hinge hole through a rotating pin.

[0036] In an embodiment of the present utility model, as Figure 2 shown, the linkage assembly 14 further includes a fixing member 143. The fixing member 143 is disposed on the top of the housing assembly 11, and the sliding member 141 is slidably engaged with the fixing member 143 in the front and back directions. The fixing member 143 is disposed on the top of the housing assembly 11 through a threaded fastener, and its function is to limit the sliding direction of the sliding member 141, thereby ensuring the smooth opening and closing of the left door body 12 and the right door body 13.

[0037] In an embodiment of the present utility model, as Figure 2 shown, a sliding groove is provided on the sliding member 141. The linkage assembly 14 further includes two limit screws 144 that are arranged at intervals in the front and back directions. The limit screws 144 pass through the sliding groove and are threadedly connected to the fixing member 143. Two convex platforms that are spaced apart in the front and back directions are protruded on the top of the fixing member 143. Threaded holes are provided on the convex platforms. The threaded portion of the limit screw 144 is connected to the threaded holes on the convex platforms. At the same time, a gasket is further provided between the head of the limit screw 144 and the sliding member 141, which can play a role in preventing loosening. The sliding groove is a strip-shaped hole, and the length of the strip-shaped hole is greater than the distance between the two limit screws 144. The limit screws 144 not only play a guiding role, but also play a role in limiting the distance of the sliding member 141 sliding back and forth. In addition to adopting the cooperation mode of the sliding groove and the limit screws 144, a guide rail or a guide groove can also be adopted to achieve sliding cooperation.

[0038] In an embodiment of the present utility model, as Figure 2As shown, a magnetic attraction part 1413 is provided on the front side of the sliding part 141. The linkage component 14 further includes a magnet 145. The magnet 145 is arranged on the top of the housing component 11 near the front opening through a fixed seat. The magnetic attraction part 1413 is specifically arranged on the front side of the hinge part 1412 and is integrally bent with the hinge part 1412. When the sliding part 141 slides forward until the magnetic attraction part 1413 contacts and magnetically attracts the magnet 145, the left door body 12 and the right door body 13 are in the fully opened position. By arranging the magnet 145 at this position, it can play a role in fixing the left door body 12 and the right door body 13, making them keep the opened state and not easy to be pushed, which is convenient for users to operate. When closing is needed, the user needs to apply an external force to the left door body 12 or the right door body 13 to make the magnetic attraction part 1413 separate from the magnet 145, and then the sliding part 141 can slide backward to close the front opening.

[0039] In an embodiment of the present utility model, as Figure 2 shown, the linkage component 14 further includes a return spring 146. One end of the return spring 146 is fixedly connected to the sliding part 141, and the other end of the return spring 146 is fixedly connected to the rear side of the housing component 11. Two return springs 146 are provided in the present utility model. The two return springs 146 are specifically arranged at both ends of the hinge part 1412. Hook parts convenient for installation are provided at both ends of the return spring 146. When the left door body 12 and the right door body 13 are opened, the return spring 146 is in a stretched state. At the same time, the magnetic attraction part 1413 of the sliding part 141 is attracted to the magnet 145, and the spring force of the return spring 146 is balanced with the magnetic attraction force. When the front opening needs to be closed, the magnetic attraction part 1413 moves away from the magnet 145, and the return spring 146 contracts to achieve reset, driving the sliding part 141 to slide backward. The sliding part 141 slides to make the two driving parts 142 swing, and the left door body 12 and the right door body 13 are closed under the action of the pulling force of the return spring 146. By arranging the return spring 146, the automatic closing of the left door body 12 and the right door body 13 can be realized, that is, the user only needs to push any one of the door bodies to make the magnetic attraction part 1413 separate from the magnet 145, and then the two door bodies can be closed by the drive of the return spring 146, making the use process more convenient.
