[0002] An oven, also called a baking oven, a drying oven, etc., uses heating tubes to heat in a closed space. After generating high temperature, it bakes food through heat conduction. Compared with open - fire charcoal roasting, the oven avoids direct contact with the heat source and generates no fumes, and is suitable for cooking whole chickens, thick steaks, cakes, bread and other foods.

[0003] Currently, the door of an existing oven is generally a single - door oven, and the oven door is opened or closed by a downward - opening or side - opening method. However, the single - door structure of the oven causes a large movement amplitude of the door when opening and closing, occupying a large operating space, and is not suitable for use in a kitchen with a small space. To address the small - space kitchen, double - door ovens have been introduced on the market. For example, the opening linkage structure and double - door oven of the double - door oven disclosed in the patent application number 201821906961.9. Although this kind of oven can be opened with only one hand through the linkage structure, the tension springs on its left and right sides are directly hung on the oven shell without a limiting structure. When opening the door with one hand, it is easy to swing left and right, resulting in the need to apply a large force to the door and the door connecting rod when opening the door with one hand, making it difficult and inconvenient to open the door with one hand.

[0004] Therefore, based on the above problems, we designed an opening linkage structure of a double - door oven. Content of the Utility Model

[0029] Specifically, a sliding shaft bracket 16 and a sliding shaft fixing seat 13 are provided on the outer side of the housing 2. Both ends of the sliding shaft 12 are installed on the sliding shaft fixing seat 13 and the sliding shaft bracket 16 respectively through fixing screws. The other side of the tension spring 14 is connected to the sliding shaft fixing seat 13. When any side door is opened, the door connecting rod drives the slide block 15 to slide on the sliding shaft 12, and at the same time the other side door will also open accordingly; the slide block 15 and the sliding shaft fixing seat 13 are connected by the tension spring 14, so that the door can automatically reset when closing;

[0030] As Figure 2 and 4As shown in the figure, during implementation, it further includes a positioning structure 3. The positioning structure 3 includes a positioning pin bracket 31 provided on the side of the slider 15, a positioning pin 32 movably inserted through the positioning pin bracket 31, and a spring 33 sleeved on the positioning pin 32.

[0031] Specifically, an installation groove 151 is provided through the slider 15. The positioning pin 32 and the spring 33 are arranged in the installation groove 151. A socket 152 for installing the positioning pin 32 is provided on the side of the sliding shaft 12. During installation, by pulling the positioning pin 32 to compress the spring 33, the position of the slider 15 can be slidably adjusted, which is convenient for fixing the slider 15 when opening and closing the door. A positioning pin bracket 31 is installed on the side of the slider 15. The positioning pin 32 is installed between the slider 15 and the positioning pin bracket 31, and the positioning pin 32 is equipped with a spring 33.

[0033] During the implementation of this embodiment, it should also be noted that the actual dimensions of each component in the application document are selected for installation before implementation according to the actual on-site requirements. In addition, this application document only aims at the existing double-door structure of the oven, where the tension springs on both the left and right sides are directly hung on the oven housing without a limiting structure. When opening the oven door with one hand, it is easy to swing left and right, resulting in the need to apply a greater force to pull the door and the door link with one hand, making it difficult and inconvenient to open the door with one hand. It does not involve improvements in internal components and other aspects. The working principle of the opening linkage structure of this double-door oven is introduced as follows:

[0034] When the present utility model is installed and used, when the user opens any one side of the door through the left door link 11, the right door link 17 and the slider 15, the other side of the door will open simultaneously. Since the sliding shaft 12 is fixed on the sliding shaft fixing seat 13 and the sliding shaft bracket 16, the slider 15 can slide back and forth on the sliding shaft 12. One end of the left door link 11 and the right door link 17 are respectively connected to the left oven door 21 and the right oven door 22, and the connection is rotatable. The other ends of the left door link 11 and the right door link 17 are respectively connected to the slider 15, and the connection is rotatable.

[0035] When any side door is opened, the door connecting rod drives the slider 15 to slide on the sliding shaft 12, and at the same time the other side door will also open accordingly; a tension spring 14 is connected between the slider 15 and the sliding shaft fixing seat 13 so that the door can automatically reset when closing; a positioning pin bracket 31 is installed on the side of the slider 15, the positioning pin 32 is installed between the slider 15 and the positioning pin bracket 31, and a spring 33 is installed on the positioning pin 32. When the door is opened to the maximum angle, the head of the positioning pin 32 will latch at the socket 152 of the sliding shaft 12 to fix the position of the door and prevent it from being directly pulled back by the tension spring 14. When closing the door, a little force is required for the door to automatically return to the closed state.

[0036] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
