[0002] In high-temperature environments, traditional socket boxes are prone to overheating and damage to internal electrical components due to the lack of effective heat insulation structures. To solve this problem, the design technology of heat insulation lining structure inside high-temperature socket boxes has emerged. The main heat insulation materials used are ceramic fiber, glass fiber, heat insulation cotton, etc., as well as heat insulation structures such as air layer and reflective layer.

[0003] In existing technologies, in high-temperature workshop environments, socket boxes are located near steam pipes or heating furnaces at the top and near underfloor heating and heat conduction equipment at the bottom. Traditionally, insulation materials are fixed to the inner lining plate by welding or bolting. This results in the need to completely disassemble the socket box to replace the insulation material after it is damaged. This leads to problems such as long replacement process, large equipment wear and tear, high safety risks, and insufficient insulation performance.

[0004] To address this, a heat-insulating inner lining structure for a high-temperature resistant socket box is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a heat-insulating inner lining structure for a high-temperature resistant socket box, which can solve the problems of long replacement process, high equipment wear and tear, and high safety risks in existing systems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating inner lining structure for a high-temperature resistant socket box, comprising a socket box body, wherein the top and bottom of the inner side of the socket box body are movably connected to a convenient replacement mechanism, and the inner side of the convenient replacement mechanism is movably connected to a double heat-insulating ventilation component; The convenient replacement mechanism includes two heat-insulating layers inside the socket box body, with the two heat-insulating layers respectively located at the top and bottom of the socket box body body. A hollow horizontal bar is fixedly connected to the rear side of the heat-insulating layer, and a hollow box is fixedly connected to the rear side of the hollow horizontal bar. Hollow vertical bars are fixedly connected to both sides of the front side of the hollow horizontal bar, and a single-port sliding rail is fixedly connected to the opposite side of the two hollow vertical bars. A snap-fit ​​limiting component is movably connected to the inner side of the hollow horizontal bar, the hollow vertical bar, and the hollow box.

[0007] Preferably, the dual heat insulation ventilation assembly includes two inner lining slide plates slidably connected to the inner side of the single-port slide rail, and the two inner lining slide plates are respectively distributed on opposite sides of the two single-port slide rails.

[0009] Preferably, the top and bottom of the ventilation plate and the inner lining slide are both fixedly connected with heat insulation plates.

[0010] Preferably, the snap-fit ​​limiting component includes a first telescopic column fixedly connected to the inside of the hollow box, and the first telescopic column is fixedly connected to the rear side of the inside of the hollow box. A compression spring is fixedly connected to the inner side of the first telescopic column, and a blocking block is fixedly connected to the front side of the first telescopic column.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up a convenient replacement mechanism, can quickly install and remove double insulation materials by opening a heat insulation layer on the outer shell of the socket box and combining it with a hollowed-out horizontal bar, a hollowed-out vertical bar and a single-port sliding rail. The L-bar is squeezed by the barrier block to achieve limited fixation. When replacing, the damaged material can be pulled out by simply pushing the limit plate, without completely disassembling the box. This shortens the replacement process, reduces equipment wear and personnel safety risks, and ensures continuous temperature control through easily replaceable insulation materials. It solves the problems of cumbersome replacement, high wear and tear and insufficient insulation performance of insulation materials after damage under traditional welding or bolting methods. 2.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A heat-insulating inner lining structure for a high-temperature resistant socket box includes a socket box body 1. The top and bottom of the inner side of the socket box body 1 are movably connected to a convenient replacement mechanism 2. The inner side of the convenient replacement mechanism 2 is movably connected to a double heat-insulating ventilation component 3. The convenient replacement mechanism 2 includes two heat-insulating layers 21 opened inside the socket box body 1, and the two heat-insulating layers 21 are respectively opened at the top and bottom of the socket box body 1. A hollow horizontal bar 22 is fixedly connected to the rear side of the heat-insulating layer 21, and a hollow box 23 is fixedly connected to the rear side of the hollow horizontal bar 22. Hollow vertical bars 24 are fixedly connected to both sides of the front side of the hollow horizontal bar 22. A single-port sliding rail 25 is fixedly connected to the opposite side of the two hollow vertical bars 24. A snap-fit ​​limiting component 26 is movably connected to the inner side of the hollow horizontal bar 22, the hollow vertical bar 24 and the hollow box 23.

[0019] In this embodiment: instead of directly bolting or welding the heat insulation material behind the inner lining plate, two sets of heat insulation layers 21 are opened at the original location of the heat insulation material on the outer shell of the socket box body 1, penetrating the front and back of the outer shell. A hollow horizontal bar 22 is set on the rear side of the heat insulation layer 21 to block its rear opening. Two hollow vertical bars 24 are fixedly connected to the two sides of the front side of the hollow horizontal bar 22. A hollow box 23 is also set on its rear side. The hollow horizontal bar 22, the hollow vertical bar 24 and the hollow area inside the hollow box 23 are connected to form a complete body. The two hollow vertical bars 24 are respectively fixed on the inner sides of the heat insulation layer 21. Each of their opposite sides is equipped with a single-opening sliding rail 25 with one side facing forward, which is used to install double heat insulation materials. The locking and limiting components 26 are used to achieve the convenient disassembly and assembly effect of limiting the installation after pushing in.

[0020] Specifically, such as Figure 1 , Figure 5 As shown, the double heat insulation ventilation assembly 3 includes two inner lining slide plates 31 that are slidably connected to the inner side of the single-port slide rail 25, and the two inner lining slide plates 31 are respectively distributed on opposite sides of the two single-port slide rails 25.

[0021] Specifically, such as Figure 1 , Figure 5 As shown, ventilation plates 32 are fixedly connected to the front and rear sides of the two inner lining slide plates 31 on opposite sides, and ventilation openings 33 are provided on the inner side of the ventilation plates 32.

[0022] Specifically, such as Figure 1 , Figure 5 As shown, the top and bottom of the ventilation plate 32 and the inner lining slide plate 31 are both fixedly connected with heat insulation plates 34.

[0023] In this embodiment: quick installation is achieved by the cooperation of the left and right inner sliding plates 31 with the single-port sliding rail 25. Ventilation openings 33 are opened in the front and rear ventilation plates 32 to promote air circulation and heat dissipation. After the top and bottom insulation plates 34 composed of ceramic or insulation cotton are assembled, a hollow air layer is formed inside. The low thermal conductivity of air enhances the heat insulation effect. Its modular structure allows each component to be disassembled and replaced independently without disassembling the socket box body 1. It achieves double heat insulation through the air layer and insulation material, improves temperature control performance, and prevents heat accumulation with the help of ventilation design. It solves the problems of cumbersome replacement of traditional fixed insulation materials and insufficient heat insulation and heat dissipation performance.

[0024] Specifically, such as Figure 2 , Figure 3As shown, the snap-fit ​​limiting component 26 includes a first telescopic post 26a fixedly connected to the inside of the hollow box 23, and the first telescopic post 26a is fixedly connected to the rear side of the inside of the hollow box 23. A compression spring 26b is fixedly connected to the inside of the first telescopic post 26a, and a blocking block 26c is fixedly connected to the front side of the first telescopic post 26a. L-rods 26d are provided on both sides of the blocking block 26c, and the L-rods 26d are provided on the inside of the hollow horizontal bar 22 and the hollow vertical bar 24.

[0025] Specifically, such as Figure 2 , Figure 3 As shown, a second telescopic column 26e is fixedly connected to the opposite side of each of the two L rods 26d. A tension spring 26f is fixedly connected to the inner side of the second telescopic column 26e. A limit plate 26g is fixedly connected to the opposite side of each of the two L rods 26d. The limit plate 26g is located on the front side of the single-port sliding rail 25.

[0026] In this embodiment: after the inner sliding plates 31 on both sides are inserted into the front of the single-port sliding rail 25, they are pushed towards the rear of the single-port sliding rail 25. When pushed to the deepest point, the rear ventilation plate 32 will squeeze the blocking block 26c inside the hollow crossbar 22, causing the blocking block 26c to move into the hollow box 23 and shorten the distance between it and the hollow box 23. The first telescopic column 26a and its internal compression spring 26b between the blocking block 26c and the hollow box 23 are then compressed. During the pushing process, the diameter of the blocking block 26c gradually decreases, and the two sets of L-bars 26d that were originally blocked by it move inward at the same time. The short side of the L-bar 26d is located inside the hollow crossbar 22 and is blocked by the blocking block 26c. The long side is set inside the hollow vertical rod 24 and is connected to the inner wall through the second telescopic column 26e and its inner tension spring 26f. Under normal conditions, the tension spring 26f is in an elastic energy storage state. When the blocking block 26c moves, the tension spring 26f releases elastic potential energy. The lower end of the L rod 26d is provided with a limiting plate 26g. When it moves inward, the limiting plate 26g just blocks the front opening of the single-port sliding rail 25, completing the limiting installation. When replacing, push the limiting plates 26g on both sides and slightly pull out the heat insulation material. Under the release of the first telescopic column 26a and its inner compression spring 26b, the blocking block 26c quickly squeezes the L rod 26d to reset and open, releasing the limiting. At the same time, the tension spring 26f accumulates elastic potential energy again.

[0027] Specifically, such as Figure 1 As shown, a switch panel 4 is fixedly connected to the front side of the socket box body 1.

[0028] Specifically, such as Figure 1 As shown, a functional base 5 is fixedly connected to the bottom of the socket box body 1.

[0029] In this embodiment, the switch panel 4 and the functional base plate can be used to assist in the use of the socket box body 1.

[0030] Working Principle: In high-temperature workshop environments, when the top of the socket box 1 is close to steam pipes or heating furnaces, and the bottom is close to underfloor heating and heat transfer equipment, additional heat insulation structures such as ceramic limiters and heat insulation cotton are usually required at the top and bottom. These structures are mounted on the outside of the inner lining plate and welded or bolted to the top and bottom of the socket box 1 or near the heat insulation structure. However, in this state, when the heat insulation material suffers physical structural damage, its heat insulation function fails, its heat insulation performance significantly decreases, it cannot meet temperature control requirements, and safety hazards become prominent, threatening equipment and personnel safety, replacement requires complete disassembly. This results in a lengthy replacement process, causes some damage to the equipment, and poses certain safety risks to personnel. Therefore, to avoid... In this case, instead of directly bolting and welding the insulation material after placing it in the inner lining plate, two sets of insulation layers 21 are opened at the original location of the insulation material inside the socket box body 1, running through the front and back of the outer shell. A hollow horizontal bar 22 is set on the rear side of the insulation layer 21 to block its rear opening. Two hollow vertical bars 24 are fixedly connected to the two sides on the front side of the hollow horizontal bar 22. A hollow box 23 is also set on the rear side. The hollow horizontal bar 22, hollow vertical bars 24 and the hollow area inside the hollow box 23 are connected to form a complete body. The two hollow vertical bars 24 are respectively fixedly connected to the inner sides of the insulation layer 21. On their opposite sides, a single-opening sliding rail 25 with one side facing forward is mounted. The following double insulation materials can be installed through the single-opening sliding rail 25. Its main components are inner sliding plates 31 on the left and right sides that can slide into the single-port sliding rail 25, ventilation plates 32 with ventilation openings 33 at the front and back, and heat insulation plates 34 made of ceramic material or heat insulation cotton at the top and bottom. These components are assembled together, and after assembly, the air supply interior forms a hollow area, forming an air layer. After the material is inserted into the front side of the single-port sliding rail 25 by the inner sliding plates 31 on both sides, it is pushed towards the rear side of the single-port sliding rail 25. When it is pushed to the deepest point, the ventilation plate 32 on the rear side will squeeze the blocking block 26c located inside the hollow crossbar 22, causing the blocking block 26c to move into the hollow box 23 and shorten the distance between it and the hollow box 23. The first telescopic column 26a and its internal compression spring 26 between the blocking block 26c and the hollow box 23 are... b will also be compressed accordingly. As the blocking block 26c is pushed forward, its diameter gradually decreases, causing the two sets of L-shaped rods 26d that were originally blocked on both sides to move inward simultaneously. The shorter side of the L-shaped rod 26d is located inside the hollow horizontal bar 22 and is blocked by the blocking block 26c. The longer side is located inside the hollow vertical bar 24 and is connected to the inner wall through the second telescopic column 26e and its inner tension spring 26f. Under normal conditions, the tension spring 26f is in an elastic energy storage state. When the blocking block 26c moves, the tension spring 26f releases its elastic potential energy to achieve the above effect. The lower end of the L-shaped rod 26d is provided with a limiting plate 26g. When moving inward simultaneously, the limiting plate 26g just blocks the front opening of the single-port sliding rail 25, completing the limiting installation. When replacement is needed, simply push the limiting plates 26g on both sides.When the insulation material is slightly pulled out, the blocking block 26c, under the release of the first telescopic column 26a and its inner compression spring 26b, will quickly compress the L-rod 26d to reset and open, releasing the limit. This also allows the tension spring 26f to accumulate elastic potential energy again. In summary, this achieves the insulation of the internal insulation lining structure of the high-temperature socket box, making it easy to replace and maintain.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
