Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer printing, in particular to a heat transfer printing device. Background Art

[0002] In the current market, the mold design of heat transfer printing devices is mostly fixed, customized for products with specific sizes and shapes. This means that whenever products of different sizes need to be printed, operators must manually replace the mold. This fixed mold design not only increases the operation complexity but also significantly raises the production cost. The heat transfer printing device with a fixed mold also lacks flexibility and is difficult to adapt to the rapid growth of the market demand for personalized customization. Customers expect to be able to print products of various sizes and shapes on the same device. However, the existing fixed mold design cannot meet this demand, restricting the market application potential of the device. Taking mobile phone case products as an example, the fixed-size mold design cannot flexibly adapt to the increasingly diverse mobile phone models and their size changes in the market. Whenever a new mobile phone model is launched or the size of an existing mobile phone is slightly adjusted, it is necessary to redesign and manufacture molds of corresponding sizes, which not only increases the production cost but also prolongs the product launch cycle and reduces the market competitiveness.

[0044] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0045] To enable those skilled in the technical field to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] As Figures 1-4 shown, a thermal transfer device provided by an embodiment of this utility model includes a first cabin 1, a second cabin 2, and a telescopic member 3.

[0047] The telescopic member 3 includes a sub-member group 31, a row sliding assembly 32, and a column sliding assembly 33; the sub-member group 31 includes sub-member blocks 311 arranged in a first number of rows and a second number of columns. The upper ends of the row sliding assembly 32 and the column sliding assembly 33 are respectively connected to the sub-member group 31. The column sliding assembly 33 drives each column of sub-member blocks 311 in the sub-member group 31 to expand and contract in the row direction, and the row sliding assembly 32 drives each row of sub-member blocks 311 in the sub-member group 31 to expand and contract in the column direction.

[0048] The first cabin 1 is arranged above the second cabin 2.

[0049] The first cabin 1 includes a first cabin bottom plate 101, a first cabin peripheral side wall 102, and a first cabin upper cover 103. The first cabin bottom plate 101, the first cabin peripheral side wall 102, and the first cabin upper cover 103 form a closed internal space of the first cabin 1. The sub-member group 31 is arranged in the internal space of the first cabin 1. The sub-member group 31 is arranged above the first cabin bottom plate 101, and the sub-member group 31 is used to carry the product to be thermally transferred.

[0050] The second cabin 2 includes a second cabin bottom plate 201, a second cabin peripheral side wall 202 and a second cabin upper cover 203. The second cabin bottom plate 201, the second cabin peripheral side wall 202 and the second cabin upper cover 203 form the internal space of the second cabin 2.

[0051] A number of opposite through holes are provided in the first cabin bottom plate 101 and the second cabin upper cover 203 to form a number of channels 4. The row sliding assembly 32 and the column sliding assembly 33 are installed below the upper cover of the second cabin 2, and the upper ends of the row sliding assembly 32 and the column sliding assembly 33 respectively pass through the corresponding channels 4 and are connected to the sub-component group 31.

[0052] In this embodiment, the first cabin 1 is located above the heat transfer printing device, and the sub-component group 31 of the telescopic member 3 is placed inside. The second cabin 2 is located below the first cabin 1, and components for driving the telescopic expansion of the sub-component group 31 are installed inside. The telescopic member 3 is used to achieve the telescopic function of the mold. The sub-component group 31 is composed of a plurality of sub-component blocks 311, and these sub-component blocks 311 are arranged in the manner of a first number of rows and a second number of columns to form a telescopic array of sub-component blocks 311. The flexible adjustment of the mold size of the heat transfer printing device is achieved through the above three main components.

[0053] The above sub-component group 31 is made of high-temperature resistant materials, such as metal materials, etc. Positioning holes or grooves can be provided on the first cabin bottom plate 101 to define the position of the sub-component group 31 and ensure its stability during the telescopic process. Among the above sub-component group 31, the sub-component blocks 311 except for the outermost row and the outermost column (i.e., the inner sub-component blocks 311) are all cubic structures with a rectangular cross-section. In a preferred embodiment, their cross-sections are all square. Setting the inner sub-component blocks 311 as regular cubic structures facilitates the uniform stretching and alignment and closing of each sub-component block 311 during the telescopic process of the telescopic member 3.

[0054] In the initial state, the sub-component group 31 can be set to a contracted state, and each sub-component block 311 is closely arranged above the bottom plate 101 of the first cabin, forming a compact array of sub-component groups 31. During use, according to the size of the product, adjustment instructions are sent to the row sliding component 32 and the column sliding component 33 through a control system (not shown in the figure). The row sliding component 32 and the column sliding component 33 respectively drive the row and column sub-component blocks 311 in the sub-component group 31 to expand and contract in the corresponding directions until a size of the sub-component group 31 that matches the size of the product to be heat-transferred is formed. The product to be heat-transferred is placed on the adjusted sub-component group 31, and the heat transfer film is placed between the upper cover 103 of the first cabin and the peripheral side wall 102 of the first cabin, and then the heat transfer program is started. The first cabin 1 and the second cabin 2 jointly provide the necessary temperature and vacuum conditions for the heat transfer process. During the vacuum pumping process, the heat transfer film is adsorbed onto the surface of the product to be heat-transferred, and then the heat transfer process at high temperature is implemented. Regarding how to perform heat transfer, it is prior art well-known to those skilled in the art, and the present utility model will not elaborate herein.

[0055] For the vacuum pumping process of the heat transfer device, exemplarily, the vacuum pumping device can be a vacuum pump (not shown in the figure), which is arranged inside the second cabin 2 or outside the first cabin 1 and the second cabin 2 of the heat transfer device. The vacuum pump is connected to the inside of the first cabin 1 through a pipeline. Specifically, the vacuum connection pipeline is arranged on the bottom plate 101 of the first cabin 1, so as to extract the air inside the first cabin 1 from the bottom of the first cabin 1 before heat transfer, so as to adsorb the heat transfer film onto the product to be heat-transferred. For the heating process of the heat transfer device, exemplarily, the heating element can be a heating element and a temperature sensor (not shown in the figure) installed inside the first cabin 1. The heating element can be, for example, a resistance wire, an electric heating tube or other forms of heating devices, so as to transfer heat to the product to be heat-transferred. The control system sends instructions to the heating element according to the preset heat transfer parameters (such as temperature, time, etc.) to adjust its heating power to reach the required heat transfer temperature. The temperature sensor feeds back the temperature information to the control system for closed-loop control. After the heat transfer is completed, in order to take out the product, a pressure relief operation needs to be performed to allow air to re-enter the inside of the first cabin 1, so that the pressure inside the cabin gradually returns to the normal level, so as to smoothly open the upper cover 103 of the first cabin. For example, a pressure relief hole can be opened on the upper cover 103 of the first cabin or the peripheral side wall 102 of the first cabin. It can be understood that existing heating elements and vacuum pumping devices in the prior art can also be used to implement the above-mentioned processes of adjusting the pressure and temperature inside the cabin.

[0056] The embodiments of the present utility model can adapt to heat transfer products of different sizes, without the need to frequently replace the mold, greatly improving the flexibility and production efficiency of the heat transfer device, reducing the production cost, improving the production efficiency and product quality, and having significant technical advantages and market application prospects. At the same time, the embodiments of the present utility model set the first cabin 1 and the second cabin 2 separately and independently, so as to place the sub-component group 31 that needs to be heated at high temperature, the heat transfer product to be processed, etc. in the first cabin 1, and place the structures that do not need and / or are not suitable for high temperature in the second cabin 2. The temperatures of the two cabins do not affect each other, thus greatly improving the service life of the heat transfer device.

[0057] As Figure 3 , Figure 5 and Figure 6 shown, in a specific embodiment, the sub-component group 31 further includes a first number of first guide posts 312 and a second number of second guide posts 313;

[0058] Each sub-component block 311 is provided with a first guide hole 3111 arranged along the row direction and a second guide hole 3112 arranged along the column direction; a first guide post 312 sequentially passes through the first guide holes 3111 of a row of sub-component blocks 311, and a second guide post 313 sequentially passes through the second guide holes 3112 of a column of sub-component blocks 311;

[0059] At least one column sliding assembly 33 is arranged in the row direction, and the column sliding assembly 33 is connected to at least one sub-component block 311 in the outermost column; at least one row sliding assembly 32 is arranged in the column direction, and the row sliding assembly 32 is connected to at least one sub-component block 311 in the outermost row.

[0060] In this embodiment, each sub-component block 311 is respectively provided with a first guide hole 3111 and a second guide hole 3112. The first guide hole 3111 is arranged along the row direction, and the second guide hole 3112 is arranged along the column direction, that is, on a sub-component block 311, the first guide hole 3111 and the second guide hole 3112 are perpendicular, and the first guide hole 3111 and the second guide hole 3112 are located at different heights of the sub-component block 311. The heights of the first guide holes 3111 on different sub-component blocks 311 are the same, and the heights of the second guide holes 3112 on different sub-component blocks 311 are the same. The sizes of the first guide hole 3111 and the second guide hole 3112 can be determined according to the specific use scenario of the telescopic member 3. For the inner layer sub-component block 311, both the first guide hole 3111 and the second guide hole 3112 are through holes. For the sub-component block 311 in the outermost row or the outermost column, the first guide hole 3111 and the second guide hole 3112 are non-through holes.

[0061] The first guide column 312 and the second guide column 313 are both cylindrical and can be made of high-strength steel. The surface is smoothed, and the end of the guide column is provided with a smooth chamfer structure to reduce the friction and collision with the sub-component block 311 during the telescopic process. When the sub-component group 31 is contracted to the minimum size, a first guide column 312 can pass through each sub-component block 311 in a row of sub-component blocks 311; a second guide column 313 can pass through each sub-component block 311 in a column of sub-component blocks 311. When the sub-component group 31 is stretched outward, when only fine-tuning is performed, for example, when the stretching size does not exceed the width of one sub-component block 311, the peripheral sub-component blocks 311 will not fall off from the first guide column 312 or the second guide column 313, so that the telescopic member 3 can maintain the stability of the overall structure during the fine-tuning and telescopic process.

[0062] The outer sub-component block 311 is pushed and pulled by the row sliding component 32 and the column sliding component 33 to drive the sub-component group 31 to extend and retract, thereby changing the size of the telescopic component 3 .

[0063] When in use, in the initial state, all sub-component blocks 311 are closely arranged on the first cabin bottom plate 101, and the guide column passes through the first guide hole 3111 and the second guide hole 3112 of each sub-component block 311 to form a sub-component group 31 with an initial size (minimum size). When the size of the sub-component group 31 needs to be adjusted to accommodate products to be thermally transferred of different sizes (such as mobile phone cases), the sub-component blocks 311 of the outermost row / column can be driven to extend and retract in the row / column direction by operating the row sliding assembly 32 and the column sliding assembly 33. After adjusting to the appropriate size, the user can fix the slider at the corresponding position on the bottom plate to achieve the size adjustment of the telescopic member 3.

[0064] The telescopic member 3 of the embodiment of the utility model is provided with a plurality of sub-component blocks 311, a first number of first guide posts 312, a second number of second guide posts 313, a row sliding assembly 32 and a column sliding assembly 33; the plurality of sub-component blocks 311 are arranged in an array, and are combined by the first guide posts 312 and the second guide posts 313, and then the sub-component blocks 311 are pulled to move by the row sliding assembly 32 and the column sliding assembly 33, thereby realizing the free telescopic function in the column direction and the row direction, so as to flexibly adapt to products of different sizes. The cooperation between the guide posts and the guide holes can limit the displacement and shaking of the sub-component blocks 311, so that the entire telescopic member 3 can maintain a high structural strength and positioning accuracy when adjusting the size. By adjusting the relative position of the sub-component blocks 311 in the row direction and the column direction, the size of the sub-component group 31 can meet the predetermined requirements of the product, thereby greatly reducing the need for new molds and reducing the cost of use.

[0065] like Figures 2-6As shown, in a specific embodiment, the row sliding assembly 32 includes a row sliding block 321, a row sliding plate 322, and a row movable lead screw 323. The row sliding block 321 passes through the channel 4. The upper end of the row sliding block 321 is connected to one of the outermost row of the sub-component blocks 311. The lower end of the row sliding block 321 is connected to the row movable lead screw 323. The row sliding plate 322 is connected to the outer side of the row sliding block 321, and the row sliding plate 322 is disposed above the first cabin floor 101 and covers the corresponding channel 4.

[0066] The column sliding assembly 33 includes a column sliding block 331, a column sliding plate 332, and a column movable lead screw 333. The column sliding block 331 passes through the channel 4. The upper end of the column sliding block 331 is connected to one of the outermost column of the sub-component blocks 311. The lower end of the column sliding block 331 is connected to the column movable lead screw 333. The column sliding plate 332 is connected to the outer side of the column sliding block 331, and the column sliding plate 332 is disposed above the first cabin floor 101 and covers the corresponding channel 4.

[0067] In this embodiment, for the row sliding assembly 32, specifically, the row sliding block 321 includes a first vertical portion 3211 having a long strip structure. The first vertical portion 3211 passes through the above-mentioned channel 4. The width of the first vertical portion 3211 is slightly smaller than the diameter of the channel 4 to ensure that it can smoothly pass through the channel 4 and slide therein. One end of the row sliding block 321 is integrally connected to one or more of the outermost row of sub-component blocks 311, or is firmly connected through a connecting member (not shown in the figure, such as a bolt, a pin, etc.) so as to be able to drive the entire row of sub-component blocks 311 to move during sliding.

[0068] The row movable lead screw 323 is connected to the other end of the row sliding block 321 and serves as a power source or an adjustment mechanism for driving the row sliding block 321 to slide. The row movable lead screw 323 is disposed in the second cabin 2. Specifically, it is disposed at the bottom of the second cabin upper cover 203. By rotating the lead screw, the moving distance of the row sliding block 321 can be accurately controlled, so as to realize the fine adjustment of the size of the sub-component group 31 in the row direction. One end of the lead screw may be provided with a rotating handle or connected to a driving device such as a motor for the user to perform manual or automatic operations. In a specific embodiment, as Figure 4 shown, by disposing a measuring potentiometer 5 at a position in the second cabin 2 and near the bottom of the row sliding block 321. Specifically, the measuring potentiometer 5 can be installed at the bottom of the second cabin upper cover 203 to track the size adjustment amplitude of the sub-component group 31 in the row direction.

[0069] The row sliding plate 322 is connected to the outer side of the row sliding block 321 and is located on the upper surface of the bottom plate 101 of the first cabin. Its shape and size match those of the channel 4 and are used to always cover the channel 4 during the sliding process of the row sliding block 321, ensuring the integrity of the structure of the bottom plate 101 of the first cabin and avoiding vacancies on the bottom plate 101 of the first cabin, thereby facilitating the realization of the vacuum pumping process of the first cabin 1.

[0070] For the column sliding assembly 33, its structure is similar to that of the row sliding assembly 32, and will not be elaborated here one by one. The difference is that it is arranged in the column direction.

[0071] In this embodiment, the telescopic member 3 precisely adjusts the size of the sub-member group 31 through the row sliding assembly 32 and the column sliding assembly 33, improving the versatility and flexibility of the telescopic member 3, and also reducing the mold cost and maintenance difficulty.

[0072] As Figures 2-6 shown, in a specific embodiment, two column sliding assemblies 33 are arranged in the row direction, and the two column sliding assemblies 33 are respectively connected to two outermost column sub-member blocks 311 that are opposite to each other. Two row sliding assemblies 32 are arranged in the column direction, and the two row sliding assemblies 32 are respectively connected to two outermost row sub-member blocks 311 that are opposite to each other.

[0073] In this embodiment, by controlling the operation of the row active lead screw 323, the two column sliding assemblies 33 drive the sub-member group 31 to perform telescopic movement in the row direction from both ends simultaneously inwards or outwards. Similarly, by controlling the operation of the column active lead screw 333, the two row sliding assemblies 32 drive the sub-member group 31 to perform telescopic movement in the column direction from both ends simultaneously inwards or outwards.

[0074] In a specific embodiment, a telescopic assembly (not shown in the figure) is arranged between two adjacent sub-member blocks 311. During the telescopic process of the telescopic member 3, the telescopic assembly is always in a compressed state and has an elastic force to expand outwards.

[0075] In this embodiment, telescopic components are provided between adjacent sub-component blocks 311. These telescopic components are structurally designed to always be in a compressed state throughout the entire telescopic process of the telescopic member 3, so they have an outward expansion elastic force, which can ensure that the distance between each sub-component block 311 remains basically uniform during the stretching or contraction of the sub-component group 31. The telescopic components can include, but are not limited to, elastic elements such as springs, elastic sheets, and elastic columns. These elements are placed between adjacent sub-component blocks 311 to ensure that sufficient elastic force can be generated to support or restrict their movement when the sub-component blocks 311 move relative to each other. During the telescopic process, the elastic force of the telescopic components interacts with the driving force of the transmission mechanism (such as a lead screw, etc.) to jointly control the moving speed and position of the sub-component blocks 311. Even when the sub-component group 31 is at its maximum stretched size, the telescopic components are still in a certain degree of compressed state, and the telescopic components maintain the relative position stability between the sub-component blocks 311 through their outward expansion elastic force.

[0076] In a specific embodiment, the sub-component block 311 at the central position of the sub-component group 31 is fixed on the bottom plate 101 of the first cabin, and the middle parts of the first guide post 312 and the second guide post 313 are fixed on the sub-component block 311 at the central position. During the telescopic process of the telescopic member 3, the bottom surfaces of the remaining sub-component blocks 311 except the sub-component block 311 at the central position can move on the bottom plate 101 of the first cabin.

[0077] In this embodiment, to ensure the stability and accuracy of the telescopic member 3 during the telescopic process, the sub-component block 311 at the central position of the sub-component group 31 is fixed on the bottom plate 101 of the first cabin, and at the same time, the middle parts of the first guide post 312 and the second guide post 313 are fixed on the sub-component block 311 at the central position. The sub-component block 311 at the central position can be fixed on the bottom plate 101 of the first cabin by bolts, welding or other reliable connection methods. During the telescopic process of the telescopic member 3, except for the sub-component block 311 at the central position remaining stationary, the bottom surfaces of the remaining sub-component blocks 311 will move on the bottom plate 101 of the first cabin.

[0078] As Figure 5 shown, in a specific embodiment, among the sub-component group 31, the sub-component blocks 311 in the outermost row and the outermost column except for the four top corners are of a first special-shaped structure. The first special-shaped structure includes a first sub-component body 3113 and a first stepped portion 3114. The height of the first stepped portion 3114 is the same as the height of the first sub-component body 3113. The first sub-component body 3113 is a cuboid, and the first stepped portion 3114 is provided on the side of the first sub-component body 3113 facing the outside of the sub-component group 31, and the first stepped portion 3114 does not completely overlap with the first sub-component body 3113.

[0079] In this embodiment, by designing the sub-component blocks 311 in the outermost row and outermost column (except for the sub-component blocks 311 at the four top corners) as the above-mentioned first special-shaped structure, the basic sliding function of the sub-component blocks 311 is retained, and an additional edge closing function is added.

[0080] The first sub-component body 3113 is kept in a cuboid shape, which is similar to the shape of the inner-layer sub-component blocks 311 to ensure neatness and stability during arrangement. When the telescopic component 3 is compressed to the minimum size, the first sub-component body 3113 is connected to the adjacent sub-component blocks 311 through the first guide post 312 and the second guide post 313, jointly forming the main structure of the sub-component group 31. In a specific embodiment, due to the additional structure for peripheral limit provided at the bottom of the first sub-component body 3113, the height of the first sub-component body 3113 is set to be slightly less than the height of the inner-layer sub-component blocks 311.

[0081] The first stepped portion 3114 is provided on the side of the first sub-component body 3113 facing the outside of the sub-component group 31 (i.e., the side that does not directly contact the adjacent sub-component blocks 311). The height of the first stepped portion 3114 is the same as the height of the first sub-component body 3113, but its position in the horizontal direction does not completely coincide with that of the first sub-component body 3113, forming a stepped or protruding effect. When the sub-component group 31 is stretched, gaps are formed between the surrounding sub-component blocks 311. For a thermal transfer printer, such gaps around the sub-component group 31 are not allowed because this will cause the thermal transfer film to be sucked into the surrounding gaps (while the upper surface of the sub-component group 31 will place the mobile phone case to be printed, and the mobile phone case itself blocks the upper surface gaps, so the gaps on the upper surface of the sub-component group 31 have no impact on the thermal transfer process). Therefore, it is necessary to block the outer periphery of the gaps formed when the sub-component group 31 is stretched. Through the above design in this embodiment, the first stepped portion 3114 is partially connected to the sub-component group 31 where it is located and partially covers the adjacent sub-component group 31. Thus, when the sub-component group 31 is stretched, the first stepped portion 3114 can still block the peripheral gaps of the sub-component group 31, making the telescopic component 3 in this embodiment applicable to devices such as thermal transfer printers.

[0082] Such as Figures 2-3As shown, in a specific embodiment, in the outermost sub-component block 311, the width of the first stepped portion 3114 of each sub-component block 311 in the row direction is the same as the width of the first sub-component body 3113 in the row direction; in the outermost column of sub-component blocks 311, the width of the first stepped portion 3114 of each sub-component block 311 in the column direction is the same as the width of the first sub-component body 3113 in the column direction. Through the above design in this embodiment, it is ensured that the first stepped portion 3114 does not exceed the boundary of the first sub-component body 3113, realizing the stability of the overall structure.

[0083] As Figure 5 shown, in a specific embodiment, in the sub-component group 31, the sub-component blocks 311 at the four top corners are of a second special-shaped structure. The second special-shaped structure includes a second sub-component body 3115. The two faces of the second sub-component body 3115 facing the inside of the sub-component group 31 are flat and perpendicular to each other; the two faces of the second sub-component body 3115 facing the outside of the sub-component group 31 are special-shaped faces, and each special-shaped face is provided with a receiving groove 3116. The part of the first stepped portion 3114 that does not coincide with the first sub-component body 3113 is used as a shielding portion 3117, and the receiving groove 3116 is used to receive the shielding portion 3117 of the adjacent sub-component block 311.

[0084] In this embodiment, in the sub-component group 31, the sub-component blocks 311 at the four top corners are designed as a second special-shaped structure. The basic shape of the second sub-component body 3115 is approximately a cube. The two faces of the second sub-component body 3115 facing the inside of the sub-component group 31 (i.e., the faces in contact with the adjacent sub-component blocks 311) are designed as flat faces, and these two flat faces are perpendicular to each other (i.e., two side faces of the cube) to ensure stable connection with the adjacent sub-component blocks 311.

[0085] The two faces of the second sub-component body 3115 facing the outside of the sub-component group 31 (i.e., the side faces not in direct contact with the adjacent sub-component blocks 311) are designed as special-shaped faces. Each special-shaped face is provided with a receiving groove 3116, and the shape and size of the receiving groove 3116 match those of the shielding portion 3117. For a sub-component block 311 at a top corner, there are two receiving grooves 3116 provided thereon. One receiving groove 3116 is used to receive the shielding portion 3117 of the adjacent sub-component block 311 in the row direction, and one receiving groove 3116 is used to receive the shielding portion 3117 of the adjacent sub-component block 311 in the column direction. In this way, when the sub-component group 31 is in a tensile or compressive state, the shielding portion 3117 of the adjacent sub-component block 311 can be partially or completely embedded into the receiving groove 3116 of the second sub-component body 3115, thereby achieving the closed effect at the four peripheries of the sub-component group 31 and enhancing the stability of the overall structure of the sub-component group 31.

[0086] As Figure 6 , 7 shown, in a specific embodiment, the second special-shaped structure further includes a guiding structure 3118, and the guiding structure 3118 is respectively arranged at the bottoms of two planes of the second sub-component body 3115;

[0087] The row sliding block 321 includes a first horizontal portion 3212 and a first vertical portion 3211. The first horizontal portion 3212 is arranged above the bottom plate 101 of the first cabin. The upper surface of the middle part of the first horizontal portion 3212 is fixedly connected to the outermost row of one sub-component block 311. The first vertical portion 3211 is connected to the lower surface of the first horizontal portion 3212. The first vertical portion 3211 passes through the channel 4, and a first guiding groove 3213 for accommodating the guiding structure 3118 is formed in the first horizontal portion 3212;

[0088] The column sliding block 331 includes a second horizontal portion 3312 and a second vertical portion 3311. The second horizontal portion 3312 is arranged above the bottom plate 101 of the first cabin. The upper surface of the middle part of the second horizontal portion 3312 is fixedly connected to the outermost column of one sub-component block 311. The second vertical portion 3311 is connected to the lower surface of the second horizontal portion 3312. The second vertical portion 3311 passes through the channel 4, and a second guiding groove 3313 for accommodating the guiding structure 3118 is formed in the second horizontal portion 3312.

[0089] In this embodiment, when the size of the sub-component group 31 stretched is relatively large, it may cause the outer peripheral sub-component blocks 311 to slide out from the first guiding column 312 or the second guiding column 313. Therefore, the guiding structure 3118 located on the outer peripheral sub-component blocks 311 is further arranged, and the guiding of the sub-component group 31 is realized through the cooperation of the guiding structure 3118 with the first guiding groove 3213 and the second guiding groove 3313.

[0090] Further, as Figure 7 shown, at least one of the guiding structures 3118 further includes a guiding platform 3119 and a T-shaped guiding member 3120. The bottom of the T-shaped guiding member 3120 is flush with the bottom of the second sub-component body 3115. The guiding platform 3119 is arranged above the T-shaped guiding member 3120 and is connected to one plane of the second sub-component body 3115 at one end; the guiding platform 3119 passes through at least one of the sub-component blocks 311 of the first special-shaped structure.

[0091] The T-shaped guide 3120 is installed at the bottom of two planes of the second sub-component body 3115 (i.e., the surfaces in contact with the adjacent sub-component blocks 311), and is flush with the bottom of the second sub-component body 3115. The T-shaped guide 3120 is used to provide support and guiding functions for some of the outermost and / or outermost row sub-component blocks 311. The T-shaped guide 3120 cooperates with the first guide groove 3213 and / or the second guide groove 3313, thereby realizing the structural stability of the entire sub-component group 31.

[0092] The guide platform 3119 is arranged above the T-shaped guide 3120, and one end of it is connected to a plane of the second sub-component body 3115. The guide platform 3119 is used to provide stable support for some of the outermost or outermost row sub-component blocks 311, thereby realizing the precise connection and guiding between the sub-component blocks 311.

[0093] The guide platform 3119 penetrates through at least one sub-component block 311 of the first special-shaped structure (the outermost and outermost row sub-component blocks 311 near the four top corners). Thus, when the sub-component group 31 is stretched and some of the sub-component blocks 311 slide out from the first guide post 312 or the second guide post 313, the guide platform 3119 can stabilize the positions of these sliding-out sub-component blocks 311, thereby maintaining the integrity and stability of the entire sub-component group 31.

[0094] The T-shaped guide 3120 further cooperates with the row sliding block 321 and / or the column sliding block 331, thereby ensuring the stability of the sub-component blocks 31 around the sub-component group 31. Taking the cooperation between the T-shaped guide 3120 and the row sliding block 321 as an example, specifically,

[0095] The row sliding block 321 is composed of a first horizontal part 3212 and a first vertical part 3211. Among them, the first horizontal part 3212 is arranged above the bottom plate, and the upper surface of the middle part thereof is fixedly connected to one sub-component block 311 (the first special-shaped structure) of the outermost row. The first vertical part 3211 is connected to the lower surface of the first horizontal part 3212 and passes through the channel 4 to realize the connection with the row moving lead screw in the second cabin 2. In order to cooperate with the T-shaped guide 3120, a first guide groove 3213 for accommodating the T-shaped guide 3120 is opened on the first horizontal part 3212. When the column sliding block 331 slides, the T-shaped guide 3120 in the row direction will move in the first guide groove 3213, thereby ensuring the expansion and contraction of the sub-component group 31 in the column direction.

[0096] Similarly, when the T-shaped guide 3120 cooperates with the column sliding block 331 and the row sliding block 321 slides, the T-shaped guide 3120 in the column direction will move in the second guide groove 3313, thereby ensuring the expansion and contraction of the sub-component group 31 in the row direction.

[0097] AsFigure 8 As shown, in a specific embodiment, the upper cover 103 of the first cabin is openable and closable relative to the peripheral side wall 102 of the first cabin. A first sealing rubber ring 1031 is provided on the lower surface of the upper cover 103 of the first cabin, and a second sealing rubber ring 1021 is provided on the upper surface of the peripheral side wall 102 of the first cabin. When the upper cover 103 of the first cabin and the peripheral side wall 102 of the first cabin are aligned, at least a part of the first sealing rubber ring 1031 is aligned with the second sealing rubber ring 1021.

[0098] In this embodiment, the first sealing rubber ring 1031 includes a convex portion 1032, and the second sealing rubber ring 1021 includes a groove portion 1022. When the upper cover 103 of the first cabin and the peripheral side wall 102 of the first cabin are aligned, the convex portion 1032 of the first sealing rubber ring 1031 is exactly aligned with the groove portion 1022 of the second sealing rubber ring 1021, and the convex portion 1032 of the first sealing rubber ring 1031 is embedded in the groove portion 1022 of the second sealing rubber ring 1021, thereby greatly improving the sealing and closing effect between the upper cover 103 of the first cabin and the peripheral side wall 102 of the first cabin.

[0099] As Figure 1 shown, in a specific embodiment, a heating element (not shown in the figure) is provided in the first cabin 1, a heat insulation material layer 6 is provided between the first cabin 1 and the second cabin 2, and / or the upper cover of the second cabin 2 is made of a heat insulation material.

[0100] In this embodiment, a heat insulation material layer 6 is further provided between the first cabin 1 and the second cabin 2, so as to better isolate the temperature between the first cabin 1 and the second cabin 2, and prevent the temperature of the first cabin 1 from affecting the second cabin 2, so as not to affect the service life of the electronic devices (such as the adjustment potentiometer 5, etc.) in the second cabin 2. The upper cover of the second cabin can be made of a heat insulation material, or a heat insulation coating can be applied. Of course, the entire second cabin 2 can also be further made of a heat insulation material. The heat insulation material can be, for example, heat insulation cotton, polystyrene foam board, aerogel felt, calcium silicate board, ceramic fiber board, rock wool board, aluminum silicate composite board, glass wool, etc. The heat insulation coating can be a polyurethane coating, an aerogel coating, etc.
