Description

Technical Field

[0001] This utility model relates to the field of vacuum furnaces, and more specifically, to a horizontal double-door vacuum furnace structure with strong sealing performance. Background Technology

[0002] The structure of a vacuum furnace refers to the overall construction of the various components of the equipment that enables heating and processing in a vacuum environment. It typically includes key parts such as the furnace body, heating system, vacuum system, sealing structure, and installation and fixing structure.

[0003] The existing technologies on the market still have the following shortcomings:

[0004] (1) Its sealing structure is mostly a rigid connection, which is difficult to fit tightly with the surface of the connection, causing outside air, dust and water vapor to easily enter the furnace, destroying the vacuum environment and seriously affecting the processing quality. In terms of installation and fixing, the existing technology has a simple installation structure design, and the equipment is prone to displacement or shaking due to vibration during operation, which cannot provide a reliable guarantee for the safe and stable operation of the vacuum furnace.

[0005] (2) It is inadequate in terms of ease of operation and structural rationality, and is not easy to install and maintain. It is also difficult to maintain good performance for a long time.

[0006] To address this, a horizontal double-door vacuum furnace structure with strong sealing performance is proposed. Utility Model Content

[0007] The purpose of this utility model is to address the existing problems.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The present invention is as follows: a horizontal double-door vacuum furnace structure with strong sealing performance, comprising a main body, an mounting plate fixedly connected to the bottom surface of the main body, an installation opening on the upper surface of the mounting plate, a snap-fit ​​plate on the mounting plate or the main body, and an insertion opening on the mounting plate; a limit frame on the main body, and a first hollow opening on the mounting plate.

[0010] The main body of the structure is provided with a handle and a sealing baffle; a fixing block is connected to the main body of the structure, and a nut is fixedly connected to one side of the fixing block.

[0011] A threaded rod is movably connected to one side of the nut, and a limit baffle is provided on the threaded rod.

[0012] As a preferred technical solution of this utility model, there are multiple mounting openings, and the multiple mounting openings are evenly distributed on the mounting plate.

[0013] As a preferred technical solution of this utility model, the number of the connecting plates is adapted to the snap-fit ​​positions on the drone body, and the shape of the snap-fit ​​plates matches the shape of the snap-fit ​​positions.

[0014] As a preferred technical solution of this utility model, the size of the plug-in opening matches the size of the corresponding plug-in structure on the drone body, and the inner wall surface of the plug-in opening is provided with anti-slip texture.

[0015] As a preferred technical solution of this utility model, the inner wall of the limiting frame is in contact with the outer wall of the component placed therein, thereby limiting the component.

[0016] As a preferred technical solution of this utility model, the first hollow opening is circular, square or polygonal in shape, and the edges of the first hollow opening are rounded.

[0017] As a preferred technical solution of this utility model, the outer surface of the handle is covered with an anti-slip sleeve, and the anti-slip sleeve is made of rubber.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The main structure, with its sealing baffle made of elastic material, tightly fits the connection surface, effectively preventing external air, dust, and moisture from entering the furnace, ensuring a vacuum environment and improving processing quality. Multiple evenly distributed mounting openings on the mounting plate, along with snap-fit ​​plates and insertion openings, allow for multiple fixations between the vacuum furnace and the mounting base. The fit between the snap-fit ​​plates and corresponding snap-fit ​​positions, along with the anti-slip texture on the inner wall of the insertion openings, further enhances installation stability, preventing displacement or shaking during operation and providing a reliable guarantee for the safe and stable operation of the vacuum furnace.

[0020] 2. The main structure, with its handles on the main structure or mounting plate covered in rubber anti-slip sleeves, facilitates easy opening and closing of the furnace door or moving equipment, improving operational comfort. The first perforated opening on the mounting plate reduces the overall weight of the equipment while maintaining structural strength, and the rounded corners minimize the risk of personnel bumping into things. The limiting frame's role in limiting internal components, along with the fastening structure composed of fixing blocks, nuts, threaded rods, and limiting baffles, ensures the robustness of the connections between components. The overall structural layout is reasonable, facilitating installation and maintenance while maintaining good performance over the long term. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] 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.

[0030] Please see Figures 1-4 The present invention provides a technical solution: a horizontal double-door vacuum furnace structure with strong sealing performance, including a main body 1, an mounting plate 2 fixedly connected to the bottom surface of the main body 1, an installation opening 3 on the upper surface of the mounting plate 2, and a snap-fit ​​plate 4 provided on the mounting plate 2 or the main body 1.

[0031] In this embodiment, there are multiple mounting openings 3, and the multiple mounting openings 3 are evenly distributed on the mounting plate 2. The number of connecting plates 4 is adapted to the snap-fit ​​positions on the drone body, and the shape of the snap-fit ​​plate 4 matches the shape of the snap-fit ​​position.

[0032] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the mounting plate 2 is further provided with an insertion opening 5; the structural body 1 is provided with a limiting frame 6, and the mounting plate 2 is provided with a first hollow opening 7; the structural body 1 is provided with a pull handle 8 and a sealing baffle 9.

[0033] In this embodiment, the size of the insertion opening 5 matches the size of the corresponding insertion structure on the drone body, and the inner wall surface of the insertion opening 5 is provided with anti-slip texture. The inner side wall of the limiting frame 6 fits against the outer wall of the component placed inside it, thereby limiting the component.

[0034] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a fixing block 10 is connected to the main body 1, a nut 11 is fixedly connected to one side of the fixing block 10, a threaded rod 12 is movably connected to one side of the nut 11, and a limit baffle 13 is provided on the threaded rod 12.

[0035] In this embodiment, the first hollow opening 7 is circular, square or polygonal in shape, and the edges of the first hollow opening 7 are rounded. The outer surface of the handle 8 is covered with an anti-slip sleeve, and the anti-slip sleeve is made of rubber.

[0036] Specifically, when using this highly sealed horizontal double-door vacuum furnace structure: First, install the equipment. Place the mounting plate 2 at the bottom of the main body 1 on the mounting base. Secure the mounting plate 2 with bolts or other fasteners through the multiple evenly distributed mounting openings 3 on the mounting plate 2. Simultaneously, engage the mounting plate 2 or the snap-fit ​​plate 4 on the main body 1 with the corresponding snap-fit ​​position on the mounting base. Then, insert the plug-in structure on the mounting base into the plug-in opening 5 of the mounting plate 2. The anti-slip texture on the inner wall of the plug-in opening 5 enhances the stability of the connection, achieving multiple fixations for the equipment and preventing displacement during operation. Before using the equipment, check the limiting frame 6 on the main body 1 to ensure that the outer wall of the internally placed components fits snugly against the inner wall of the limiting frame 6. The limiting frame 6 limits the components, ensuring accurate installation. The operator holds the handle 8 on the main body 1. The rubber anti-slip sleeve on the outer surface of the handle 8 provides a comfortable grip, making it easy to pull open the furnace door. After placing the workpiece into the furnace, the furnace door is closed. At this time, the sealing baffle 9 on the main body 1 fits tightly with the furnace door, ensuring a seal inside the furnace. During operation, the first hollow opening 7 on the mounting plate 2 reduces the weight of the equipment, and its rounded corners prevent personnel from bumping into it. If it is necessary to adjust the tightness of the components, the threaded rod 12 can be adjusted by rotating the nut 11 on one side of the fixing block 10 connected to the main body 1. The limit baffle 13 on the threaded rod 12 prevents the threaded rod 12 from being over-screwed and damaging the components, ensuring a firm connection. After the equipment is used, the furnace door can be opened again by pulling the handle 8 to remove the workpiece. During regular maintenance, relevant components can be disassembled and repaired through the mounting opening 3, the plug-in opening 5, etc. After maintenance, the components are reinstalled and fixed in reverse order to ensure the equipment operates normally next time.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
