[0002] Most existing furnace door opening and closing mechanisms are complex in structure, generally using at least one rotary motor and one telescopic cylinder, which are respectively set above the furnace door and on one side of the furnace door to control the opening and rotation of the furnace door. Since the output ends of the rotary motor and the telescopic cylinder are respectively equipped with corresponding output shafts connected to the furnace door rocker arm, and the two output shafts are not collinear, the space required for the overall installation of the opening and closing mechanism is large, which cannot meet the installation requirements of compact space.

[0003] Therefore, an automatic furnace door opening and closing device and a rotary lifting device are designed to solve the technical problem in the existing technology where the corresponding output shafts connected to the rotary motor and the telescopic cylinder are not collinear, resulting in a large installation space required for the overall device and failing to meet the requirements for installation in compact spaces.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0061] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0062] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0063] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such.

[0064] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0065] Research has revealed that most existing furnace door opening and closing mechanisms are complex in structure, generally employing at least one rotary motor and one telescopic cylinder to control the opening and rotation of the furnace door respectively. Since the output ends of the rotary motor and the telescopic cylinder are respectively equipped with corresponding output shafts connected to the furnace door rocker arm, and the two output shafts are not collinear, the overall space required for the opening and closing mechanism is large, which cannot meet the installation requirements of compact spaces.

[0066] Based on the above research, the present disclosure provides an automatic furnace door opening and closing device and a rotating lifting mechanism. By setting up a lifting mechanism and a rotating mechanism, and making the axes of the lifting rod and the rotating shaft in the two mechanisms collinear, the installation space occupied by the two mechanisms is reduced. This allows the two mechanisms to control the furnace door connecting arm to drive the furnace door to lift and rotate while reducing the installation space occupied, thus meeting the installation requirements of a compact space.

[0067] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0069] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0070] In some embodiments, such as Figure 1 and Figure 2As shown, when the furnace door needs to be opened (the furnace door device is not shown in the figure), air is first drawn from the air chamber 201 through the air nozzle 202. After a negative pressure is generated in the air chamber 201, the piston 203 slides upward along the inner wall of the air chamber 203. At this time, the piston 203 drives the lifting rod 23, which is connected to the bearing of the connecting rod 204, to move upward through the connecting rod 204. Figure 2 It is known that the snap-fit ​​shaft 24 passes through the lifting rod 23 and both ends of the snap-fit ​​shaft 24 are fixed to the lifting sleeve 22. At this time, as the lifting rod 23 moves upward, the lifting rod 23 slides in the slide groove 310, and the lifting sleeve 22 moves upward accordingly, thereby driving the rocker arm 12 fixed to the outer wall of the lifting sleeve 22 to move upward. The rocker arm 12 drives the furnace door connecting arm 13 to move upward. The connecting piece 21 is slidably connected to the rotating shaft 31, and its function is to fill the gap between the upper end face of the lifting sleeve 22 and the rotating shaft 31.

[0071] When the furnace door connecting arm 13 lifts the outer wall, the rotary cylinder 30 is activated, and its output end drives the rotary shaft 31 to rotate. Since the snap-fit ​​shaft 24 passes through the slide groove 310, when the rotary shaft 31 rotates, the inner wall of the slide groove 310 abuts against the snap-fit ​​shaft 24. The snap-fit ​​shaft 24 drives the lifting sleeve 22 to rotate, which in turn drives the furnace door connecting arm 13 to rotate to open the furnace door.

[0072] The lifting protective cabinet 10 and the rotating protective cabinet 11 are used to protect the pneumatic box 200 and the rotating cylinder 30, respectively.

[0073] It should be noted that the connection between the air nozzle 202 and the external negative pressure source to extract air from the air chamber 201, as well as the control of the rotary cylinder, are existing technologies. The specific control methods and installation methods will not be elaborated on here.

[0074] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0075] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0076] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0077] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0078] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
