[0031] like Figures 1 to 5As shown, the oven of the utility model comprises: an oven body 1, a first driving cylinder 3 and an angle adjustment assembly. At least one set of oven doors 2 is arranged on the upper part of the oven body 1, and the oven doors 2 are rotatably mounted on the oven body 1 on one side; the bottom end of the first driving cylinder 3 is rotatably arranged on the oven body 1, and the extended shaft end of the first driving cylinder 3 is hinged on the side where the oven door 2 is not rotatably connected to the oven body 1, and the first driving cylinder 3 is inclined; the angle adjustment assembly is arranged on the same side of the oven body 1 as the first driving cylinder 3, and the angle adjustment assembly is used to adjust the inclination angle of the first driving cylinder 3 and fix the position of the first driving cylinder 3.

[0032] See also Figure 1 In order to reduce the difficulty of opening the door 2 and reduce the weight of the door 2, the door 2 is configured on the oven body 1 to have a plurality of doors, each of which corresponds to a first driving cylinder 3 and an angle adjustment component.

[0033] See also Figure 1 The oven door 2 has only one of six sides rotatably connected to the oven body 1 , so that the oven door 2 can be opened to one side, thereby making it convenient for the staff to clean the dust accumulated in the oven body 1 and the oven door 2 .

[0034] See also Figure 3 , the first driving cylinder 3 and the angle adjustment assembly are located on the same side of the oven door 2. It should be noted that in the initial state, the angle adjustment assembly does not work, the first driving cylinder 3 is in a tilted state, and at the same time, the extended shaft end of the first driving cylinder 3 retracts so that the oven door 2 covers the oven body 1.

[0035] When the oven door 2 needs to be opened, the extended shaft end of the first driving cylinder 3 is controlled to extend. Since the extended shaft end of the first driving cylinder 3 is hinged on the side of the oven door 2, the bottom end of the first driving cylinder 3 is rotatably configured on the oven body 1. In this way, the oven door 2 can be rotated relative to the oven body 1 under the push of the extended shaft end of the first driving cylinder 3, so as to realize the opening of the oven door 2. It has the characteristics of simple structure and convenient operation, which is convenient for the staff to speed up the cleaning of dust accumulated in the oven body 1 and the oven door 2. In addition, by controlling the operation of the angle adjustment component, the posture of the first driving cylinder 3 and the inclination angle of the first driving cylinder 3 can be adjusted to achieve further control of the opening angle of the oven door 2.

[0036] In one or more embodiments, the angle adjustment component is a slide groove 41 opened in the oven body 1 along a direction perpendicular to the side of the oven door 2, a second driving cylinder 42 arranged in the slide groove 41, and a slider 43 arranged at the axial end extending out of the second driving cylinder 42 and located in the slide groove 41; wherein, the bottom end of the first driving cylinder 3 is hinged on the slider 43.

[0037] See also Figure 1 , Figure 2 The slider 43 is slidably installed in the slide groove 41, and the second driving cylinder 42 is relatively located in the slide groove 41 near the door 2. When adjusting the posture of the first driving cylinder 3, only the second driving cylinder 42 needs to control the slider 43 to move horizontally in the slide groove 41, which is convenient to operate and simple in structure.

[0038] In other possible implementations, the angle adjustment component may also be a screw module, and the bottom end of the first driving cylinder 3 is rotatably mounted on the screw module.

[0039] In one or more embodiments, the portion of the oven door 2 rotatably mounted on the top surface of the oven body 1 is configured to be detachable from the oven body 1 .

[0040] See also Figure 1 , Figure 3 When only the side of the oven door 2 that is rotatably connected to the oven body 1 is separable from the oven body 1, the oven door 2 can be removed from the oven body 1. Through this arrangement, the convenience of installing the internal components of the oven body 1 can be improved.

[0041] In one or more embodiments, a limiting block 5 is disposed on the surface of the oven door 2 on the side away from the first driving cylinder 3 , and a third driving cylinder 6 is installed directly below the limiting block 5 on the oven body 1 .

[0042] See also Figure 3 When the box door 2 needs to be separated vertically from the oven body 1, the second driving cylinder 42 is first used to control the slider 43 to move toward the box door 2, and at the same time, the extended shaft end of the first driving cylinder 3 is controlled to retract, so that the first driving cylinder 3 is in a vertical state. After that, the extended shaft ends of the first driving cylinder 3 and the third driving cylinder 6 are synchronously controlled to extend, so that the first driving cylinder 3 pushes the side of the box door 2 to move upward, and the third driving cylinder 6 pushes the limit block 5 connected to the other side of the box door 2 to move upward, so as to realize the vertical lifting of the box door 2 and the complete separation of the box door 2 from the oven body 1, further improving the convenience of the staff in cleaning the dust accumulated in the oven body 1 and the box door 2, and at the same time, it is convenient for the staff to inspect and repair various components on the oven body 1.

[0043] In one or more embodiments, the bottom surface of the stopper 5 is formed with a concave structure for accommodating the extended shaft end of the third driving cylinder 6. The concave structure can ensure the stability of the connection between the extended shaft end of the third driving cylinder 6 and the door 2 body.

[0044] In one or more embodiments, the extended shaft end of the third driving cylinder 6 is provided with a supporting assembly, which can be selectively connected to the concave structure of the limit block 5, and the supporting assembly is used to offset the lateral displacement of the box door 2 when it is fully lifted; the supporting assembly includes a sleeve 71, a supporting rod 74 and a positioning rod 75; wherein, the bottom of the sleeve 71 is connected to the extended shaft end of the third driving cylinder 6, an expansion groove 72 is formed in the sleeve 71, and a number of avoidance holes 73 are evenly arranged on the inner wall of the sleeve 71; the supporting rod 74 has a sliding portion 741 and an abutment portion 742 that are interconnected, the sliding portion 741 is slidably arranged in the expansion groove 72, and the abutment portion 742 extends out of the sleeve 71; the positioning rod 75 is slidably arranged in the avoidance hole 73 through an elastic member 76, and under the action of the elastic member 76, the end of the positioning rod 75 abuts against the surface of the abutment portion 742 to be in a static position.

[0045] It should be noted that since the protruding shaft end of the first driving cylinder 3 is hinged on the side of the box door 2, the box door 2 will produce a slight lateral displacement when being lifted or returned. If the protruding shaft end of the third driving cylinder 6 is controlled to directly enter the concave structure of the limit block 5, it is easy to cause damage to the protruding shaft end of the third driving cylinder 6, thereby reducing the service life of the third driving cylinder 6. Therefore, a support component is needed to offset the lateral displacement of the box door 2 during the lifting process.

[0046] See also Figure 4 , Figure 5 The number of avoidance holes 73 in the sleeve 71 can be 4, 8, etc., without specific limitation. Several avoidance holes 73 are evenly distributed around the central axis of the sleeve 71; in the initial state, under the action of multiple elastic members 76 and the positioning rod 75, the abutment portion 742 of the abutment rod 74 is coaxial with the sleeve 71.

[0047] When the door 2 is moved laterally during the ascent or return, the lateral force of the door 2 acts on the contact portion 742 of the push rod 74, and the contact portion 742 slides slightly in the sleeve 71 through the sliding portion 741, so that the sleeve 71 and the push rod 74 are no longer coaxial, thereby offsetting the slight displacement of the door 2 and improving the service life of the third driving cylinder 6. When the push rod 74 is no longer in contact with the limit block 5, under the action of the elastic member 76, the push rod 74 is coaxial with the sleeve 71 again, thereby achieving the reset of the push rod 74.

[0048] In one or more embodiments, the sliding portion 741 of the push rod 74 is slidably connected to the sleeve 71 via the ball 8. Through this arrangement, the friction between the push rod 74 and the sleeve 71 can be reduced, and the smoothness of the movement of the push rod 74 can be improved.

[0049] In one or more embodiments, the elastic member 76 is a spring or elastic steel.

[0050] In one or more embodiments, the abutment portion 742 of the abutment rod 74 is adapted to the concave structure, and an end of the abutment portion 742 is square or arc-shaped.

[0051] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
