[0001] This utility model specifically relates to the field of heat transfer technology, and specifically to a manually spliced ​​telescopic component and heat transfer equipment. Background Technology

[0002] With the development of the times, mobile phones have become a necessity in people's lives, and users often equip their phones with personalized phone cases. Heat transfer technology is widely used in customized phone cases due to its high efficiency, environmental friendliness, and low cost. However, in existing heat transfer equipment, the molds that hold and fix the phone cases are mostly of fixed size or partially adjustable.

[0003] In terms of expansion and contraction adjustment, most existing thermal printing molds cannot achieve flexible expansion and contraction to adapt to different sizes. Either the size is fixed, making it difficult to adapt to different product specifications; or the adjustment structure is complex, the adjustment process is cumbersome and has low precision; at the same time, the gaps at the joints of the adjustment components are large, which can easily lead to uneven heat conduction, seriously affecting the quality of thermal printing.

[0004] Therefore, in view of this, the present invention provides a manual splicing telescopic component and a heat transfer printing device to make up for and improve the shortcomings of the prior art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a manual splicing telescopic component and a heat transfer printing device to solve the related technical problems raised in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a manual splicing telescopic component, including a main base plate, a fitting cover plate fixedly provided on the top of the main base plate, and the top surface of the fitting cover plate being a horizontal plane; It also includes a longitudinal adaptation component, which is symmetrically slidably disposed on both sides of the longitudinal axis of the main substrate. It can slide horizontally towards each other along the longitudinal direction of the main substrate, and is elastically connected to both sides of the main substrate through at least two symmetrically disposed longitudinal springs. The longitudinal adaptation component includes a longitudinal sliding component and a first strip splicing group, with two groups of each, symmetrically distributed on both sides of the longitudinal direction of the main substrate. The first strip splicing group is movably inserted into the longitudinal sliding component and forms an abutment fit between the fitting cover plate and the longitudinal sliding component. The top plane of the first strip splicing group is flush with the top plane of the longitudinal sliding component and the fitting cover plate. The lateral adjustment components are symmetrically slidably disposed on both sides of the main substrate in the lateral direction, and can slide horizontally towards each other along the lateral direction of the main substrate. They are also elastically connected to both sides of the main substrate through at least two symmetrically disposed lateral springs. The lateral adjustment assembly includes an elastic slider, a limiting slider, and a second strip-shaped splicing group, with two sets of each of the three, symmetrically distributed on both sides of the main substrate in the lateral direction. The elastic slider is slidably disposed on both sides of the main substrate and slides horizontally towards each other in the lateral direction of the main substrate. The limiting slider is slidably disposed on both sides of the elastic slider in the longitudinal direction, and the limiting slider forms a sliding fit with the two longitudinal sliding parts on the same side of the main substrate in the lateral direction. The second strip-shaped splicing group is movably inserted into the limiting slider and forms an abutment fit between the fitting cover plate and the elastic slider. The top plane of the second strip-shaped splicing group is flush with the top planes of the fitting cover plate, the elastic slider, and the limiting slider.

[0007] Furthermore, a heat transfer printing device includes a heat transfer printing device body and a mold disposed within the heat transfer printing device body, the mold employing the aforementioned manual splicing telescopic component.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This manual splicing telescopic component, through the coordinated action of the longitudinal adaptation component and the lateral adjustment component, can flexibly adapt to various sizes of products to be heat-printed without the need for frequent mold changes. The interlocking design of the first and second strip splicing groups minimizes the gaps between adjacent components, avoids heat conduction interruptions, ensures consistent heat printing effects across all parts of the product, and improves the quality of the finished product. Except for the longitudinal and transverse springs, the remaining components are made of high-temperature resistant and high thermal conductivity materials to ensure efficient and uniform heat transfer, meet the rigidity requirements of heat printing, and avoid heat printing failure due to material issues. The first guide rail and the first guide groove block, the dovetail block and the dovetail groove are precisely matched, and combined with the limiting structure, the sliding is smooth and without deviation. The tops of each component are flush, so that the plastic film layer is heated evenly and flat, reducing wrinkles.

[0011] 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.

[0012] Example Please refer to Figures 1 to 7 As shown, a manual splicing telescopic component includes a main base plate 1, and a fitting cover plate 11 is fixedly provided on the top of the main base plate 1. The top surface of the fitting cover plate 11 is a horizontal plane. It also includes a longitudinal adaptation component 2, which is symmetrically slidably disposed on both sides of the longitudinal axis of the main substrate 1. It can slide horizontally towards each other along the longitudinal direction of the main substrate 1, and is elastically connected to both sides of the main substrate 1 through at least two symmetrically disposed longitudinal springs 12 to provide longitudinal reset force, so as to play an adaptive adjustment role, and cooperate with the transverse adjustment component 3 to adjust its longitudinal dimension synchronously. The longitudinal adaptation component 2 includes a longitudinal sliding component 21 and a first strip-shaped splicing group 22, with two sets of each, symmetrically distributed on both sides of the longitudinal direction of the main substrate 1. The first strip-shaped splicing group 22 is movably inserted into the longitudinal sliding component 21 and forms an abutment fit between the fitting cover plate 11 and the longitudinal sliding component 21 to ensure the tightness and stability between the longitudinal sliding component 21 and the fitting cover plate 11 after the longitudinal spring 12 is stretched or retracted. Furthermore, the top plane of the first strip-shaped splicing group 22 is flush with the top plane of the longitudinal sliding component 21 and the fitting cover plate 11. The lateral adjustment component 3 is symmetrically slidably disposed on both sides of the main substrate 1 in the lateral direction. It can slide horizontally towards each other along the lateral direction of the main substrate 1 and is elastically connected to both sides of the main substrate 1 through at least two symmetrically disposed lateral springs 13. It is used to provide lateral reset force so that it can automatically retract when the user adjusts the lateral dimension of the main substrate 1. It also works with the longitudinal adaptation component 2 to adapt to products of different sizes to be heat-printed, such as mobile phone cases. The lateral adjustment component 3 includes an elastic slider 31, a limiting slider 32, and a second strip-shaped splicing group 33, with two sets of each component symmetrically distributed on both sides of the main substrate 1. The elastic slider 31 is slidably disposed on both sides of the main substrate 1 and slides horizontally towards each other along the lateral direction of the main substrate 1. The limiting slider 32 is slidably disposed on both sides of the elastic slider 31 in the longitudinal direction, and the limiting slider 32 forms a sliding engagement with the two longitudinal sliding components 21 on the same side of the main substrate 1 in the lateral direction. Its functions are: firstly, to limit the sliding range of the lateral adjustment component 3; secondly, to enhance the degree of cooperation between the limiting slider 32 and the elastic slider 31, the elastic slider 31 and the main substrate 1, and the limiting slider 32 and the longitudinal sliding components 21, thereby improving the stability of its sliding displacement; at the same time, when the longitudinal sliding components 21 slide towards each other for adjustment, the limiting slider 32 drives the corresponding second strip-shaped splicing group 33 to move synchronously. The second strip-shaped splicing group 33 is movably inserted into the limiting sliding member 32 and forms an abutting fit between the fitting cover plate 11 and the elastic sliding member 31 to ensure the tightness and stability between the elastic sliding member 31 and the fitting cover plate 11 after the transverse spring 13 is stretched or retracted; and the top plane of the second strip-shaped splicing group 33 is flush with the top plane of the fitting cover plate 11, the elastic sliding member 31, and the limiting sliding member 32. It is worth noting that: all the connecting parts of the above-mentioned telescopic components, except for the longitudinal spring 12 and the transverse spring 13 which are made of their own elastic metal material, are made of materials with high temperature resistance and high thermal conductivity, such as metal. The telescopic components made of metal with high thermal conductivity have excellent heat transfer performance and meet the rigidity requirements of heat printing processing.

[0013] In one specific implementation, each set of longitudinal sliding components 21 includes a longitudinal sliding plate 2101, a first guide rail 2102, and a first guide groove block 2103. The longitudinal sliding plate 2101 is slidably disposed on the main substrate 1 near the main substrate 1 and can cover the side of the main substrate 1. Its top plane forms a continuous plane with the horizontal plane of the fitting cover plate 11. Its function is to ensure that the top surface of the entire telescopic component always remains flat, which is beneficial to keep the plastic film layer flat during heat printing and prevent wrinkles and defects generated during heat printing, thereby improving the aesthetics of the heat-printed product. The first guide rail 2102 is fixedly disposed at the bottom of the longitudinal sliding plate 2101 near the main substrate 1. The main substrate 1 is fixedly provided with a first guide groove block 2103 that is adapted to slide and connected to the first guide rail 2102. The sliding cooperation between the two is limited to longitudinal horizontal sliding to ensure that the two will not separate. With the elastic connection of the longitudinal spring 12, the longitudinal sliding component 21 will not separate from the sides of the main substrate 1. That is to say, the elastic force range of the longitudinal spring 12 does not allow the longitudinal sliding component 21 to separate from the main substrate 1.

[0014] Furthermore, the longitudinal sliding component 21 also includes a first limiting groove 2105 and a first limiting part 2106. The first limiting groove 2105 is integrally formed on the main substrate 1, and there are at least four of them, which are symmetrically arranged in pairs on both sides of the longitudinal direction of the main substrate 1. The first limiting part 2106 is integrally formed on the longitudinal sliding plate 2101, and there are at least four of them. The longitudinal sliding plate 2101 is slidably connected to the main substrate 1 through the corresponding first limiting part 2106 and the first limiting groove 2105, which further improves the stability of the longitudinal sliding component 21 sliding in opposite directions along the longitudinal direction.

[0015] In the second specific implementation, each first strip splicing group 22 includes a straight strip 2201, a first positioning part 2202, and a first positioning groove 2203. There are several straight strips 2201, and the width of each straight strip 2201 is 24mm, which is used to fine adjust the width of the telescopic component to better adapt to products with different widths. At least two first positioning parts 2202 are symmetrically provided on both sides of the bottom of each straight strip 2201, and at least two sets of linearly distributed first positioning grooves 2203 are symmetrically provided on both sides of the top of the longitudinal slide plate 2101. The first positioning grooves 2203 are adapted to and inserted into the corresponding first positioning parts 2202.

[0016] Specifically, the first positioning part 2202 is integrally formed on the bottom of each straight plate 2201 and has an elliptical cylindrical structure. Its bottom outer edge has an elliptical first chamfered portion. The first positioning groove 2203 is integrally formed on the top of each longitudinal slide plate 2101 and has the same shape as the first positioning part 2202. Its top edge has a second chamfered portion that matches the first chamfered portion. Each straight plate 2201 is inserted into the corresponding first positioning part 2202 and first positioning groove 2203. The telescopic component, when adjusting its longitudinal dimensions, selects an appropriate number of straight strips 2201 so that the first positioning part 2202 is inserted into the corresponding first positioning groove 2203, thereby forming an abutment fit between the longitudinal sliding plate 2101 and the fitting cover plate 11. After insertion, the gap between two adjacent straight strips 2201 is ≤0.5mm to prevent uneven heat conduction during heat transfer, thus ensuring the quality of product heat printing. The aforementioned chamfered part plays a guiding role during insertion to facilitate smooth insertion.

[0017] In the third specific implementation, the elastic sliding member 31 includes an I-beam plate 3101, an extension plate 3102, a second guide rail 3103, and a second guide slot block 3104. The extension plate 3102 is integrally formed on the side of the I-beam plate 3101 near the main substrate 1. The second guide rail 3103 is fixedly provided at the bottom of the extension plate 3102. The main substrate 1 is provided with a second guide slot block 3104 that is adapted to and slidably connected to the second guide slot block 3104. The sliding cooperation between the two is limited to horizontal sliding to ensure that the two will not separate. In conjunction with the elastic connection of the horizontal spring 13, the elastic sliding member 31 will not separate from the two sides of the main substrate 1. That is to say, the elastic force range of the horizontal spring 13 does not allow the longitudinal sliding member 21 to separate from the main substrate 1.

[0018] Furthermore, the elastic slider 31 also includes a second limiting groove 3105 and a second limiting part 3106. The second limiting groove 3105 is provided on the main substrate 1, and there are at least four of them, which are symmetrically distributed in pairs on both sides of the main substrate 1. The second limiting part 3106 is integrally formed on the extension plate 3102, and its number and position correspond to the two second limiting grooves 3105 on both sides. The two are slidably connected, which further improves the stability of the elastic slider 31 sliding in the opposite direction in the lateral direction.

[0019] In the fourth specific implementation, the limiting sliding component 32 includes a twin corner block 3201, a dovetail block 3202, and a dovetail groove 3203. The twin corner block 3201 is slidably connected to the longitudinal sides of the corresponding I-beam plate 3101. Specifically, the I-beam plate 3101 has grooves on both sides for the twin corner block 3201 to slide horizontally. The outer corner of the twin corner block 3201 is rounded, and its shape is the same as that of most mobile phone case corners on the market. However, its shape is not limited to rounded corners and can be processed into corresponding shapes according to different product shapes. In this embodiment, it is only shown for use in the heat transfer processing of mobile phone cases. This also means that the telescopic component is not limited to use in the heat transfer of mobile phone cases, but can also be applied to other occasions that require adjustment of mold size, such as printing, cutting, assembly and other fields, and has a wide range of application prospects. The dovetail block 3202 is integrally formed on the side of the twin corner block 3201 near the main substrate 1, and is slidably connected to the dovetail groove 3203 on the inner side of the bottom of the longitudinal slide plate 2101 through the dovetail block 3202. The shape of the dovetail ensures the stability of the sliding displacement.

[0020] In the fifth specific implementation, each second strip-shaped splicing group 33 includes an L-shaped strip 3301, a misalignment portion 3302, a second positioning portion 3303, and a second positioning groove 3304. Several L-shaped strips 3301 are provided, each with a width of 2-4 mm, used for fine-tuning the length of the telescopic component to better adapt to products of different lengths. Misalignment portions 3302 are provided at the ends of two L-shaped strips 3301 that are close to each other, and these portions slide in an alternating manner. The width between two adjacent misalignment portions 3302 is between 1.5 and 3 mm. In this embodiment, the width is maintained at 1.5 mm, at which point the impact on heat conduction is almost negligible; as long as the gap is controlled within 3 mm, the heat conduction requirements can be met. Each L-shaped strip 3301 has at least two second positioning parts 3303 at its bottom. The dovetail block 3202 has linearly arranged second positioning grooves 3304 on its top side near the main substrate 1. The second positioning parts 3303 and the second positioning grooves 3304 are adapted to fit and insert into each other. Specifically, the shape and structure of the second positioning parts 3303 and the second positioning grooves 3304 are the same as those of the first positioning parts 2202 and the first positioning grooves 2203 mentioned above. A suitable number of L-shaped strips 3301 are selected so that the second positioning parts 3303 are inserted into the corresponding second positioning grooves 3304 to form an abutment fit between the I-beam plate 3101 and the fitting cover plate 11. After insertion, the gap between two adjacent L-shaped strips 3301 is ≤0.5mm to prevent uneven heat conduction during heat conduction, thereby ensuring the quality of product heat printing. The aforementioned chamfered part plays a guiding role during insertion to facilitate smooth insertion.

[0021] Another embodiment of a heat transfer printing device includes a heat transfer printing device body and a mold disposed within the heat transfer printing device body, wherein the mold adopts the manual splicing telescopic component in the above embodiments; It is worth noting that the main body of this heat transfer equipment is existing technology. For details, please refer to the patent with application number 202422516600.5. When using this manual splicing telescopic component, it can be fastened to the working space of the main body of the heat transfer equipment by clamping fixtures. After the mobile phone case is put on the outside of the telescopic component, the plastic film layer is placed on top of the mobile phone case, and then the mobile phone case can be heat-printed by the main body of the heat transfer equipment.

[0022] The complete usage steps and principles of the above embodiments are as follows: When using this manual splicing telescopic component, users need to adjust the size of the component according to the size of the product to be heat-printed.

[0023] Longitudinal dimension adjustment: If the product has longitudinal dimension requirements, the user pushes the longitudinal sliding components 21 on both sides of the main substrate 1 to make them slide horizontally towards each other along the longitudinal direction of the main substrate 1. During the sliding process, the longitudinal spring 12 is stretched or retracted, and then provides longitudinal restoring force to realize the adaptive adjustment of the longitudinal sliding component 21. At the same time, the user selects an appropriate number of straight strips 2201 from the first strip splicing group 22 and inserts the first positioning part 2202 at its bottom into the corresponding first positioning groove 2203 on the longitudinal sliding component 21, forming an abutment fit between the longitudinal sliding component 21 and the fitting cover plate 11, ensuring the tightness and stability of the relevant components after longitudinal adjustment, and the top plane of the first strip splicing group 22 is flush with the top plane of other components.

[0024] Lateral dimension adjustment: The operation is similar to longitudinal adjustment. The user pushes the elastic sliding members 31 on both sides of the main substrate 1 laterally, causing them to slide horizontally towards each other along the lateral direction of the main substrate 1. The lateral spring 13 stretches or retracts accordingly and provides lateral reset force. At this time, the limiting sliding member 32 moves with the elastic sliding member 31, and drives the second strip splicing group 33 to move synchronously. The user selects an appropriate number of L-shaped strips 3301 and inserts the second positioning part 3303 at its bottom into the second positioning groove 3304 on the limiting sliding member 32 to ensure the tightness and stability between the elastic sliding member 31 and the fitting cover plate 11, while ensuring that the top plane of the second strip splicing group 33 is flush with the top plane of other components.

[0025] After adjustment, the user uses the clamping fixture to install the telescopic component in the working space of the heat transfer equipment, puts the product to be heat-printed over the telescopic component, places the plastic film layer on top of the product, and starts the heat transfer equipment to begin processing.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. It is worth noting that the fixing arrangements, fixing connections, and fixing devices in the present invention can be achieved through bolted or threaded connections or other methods that enable detachment after fixing.
