Description

Technical Field

[0001] This utility model relates to the field of shell disassembly tools, and in particular to a multifunctional shell disassembly tool for snap-fit ​​shells. Background Technology

[0002] Electronic products are designed with different concepts for different consumer groups. Luxury products have extremely high requirements in terms of materials, processing, and decoration, using the best materials, the most precise processing, and the most luxurious decoration. Affordable products, while ensuring functionality, reduce costs in the materials, processing, and decoration of structural components. Replacing metal or glass shells with plastic shells is one effective way to achieve this in affordable products.

[0003] When using plastic casings for large-screen tablets, multi-point fastening is often required on the edge fittings for secure fixation. Because the glass cover of the screen is embedded in the casing with almost no gaps around its edges, and the casing is very thin, opening the cover for disassembly, repair, or routine maintenance is difficult. Currently, the common method is to insert a pry tool (a triangular plastic strip) between the casing and the glass cover, running it around the circumference of the glass to force the casing outwards and disengage it from the fittings. This method is difficult to operate, especially finding a point of entry when inserting the pry tool between the glass cover and the casing, resulting in low efficiency. Furthermore, this method can easily lead to accidents such as glass breakage, scratches on the casing, or damage to internal circuitry, increasing repair costs.

[0004] Therefore, a new solution is needed. Utility Model Content

[0005] The main purpose of this utility model is to address the problems in the prior art where it is difficult to quantify the release force of snap-fit ​​housings and the easy damage to components when removing the cover during the repair of this type of model. It provides a multi-functional housing disassembly tool for snap-fit ​​housings to improve the work efficiency of the housing opening station during repair work and reduce abnormal repair losses.

[0006] To achieve the above objectives, this utility model provides a multifunctional shell disassembly tool for snap-fit ​​shells, comprising a rectangular main body, a shell opening portion, and a weighing connection portion. The shell opening portion is disposed at a first end of the main body, and the weighing connection portion is disposed at a second end of the main body, with the first end and the second end facing each other. The shell opening portion includes a biting body and a supporting body. The biting body extends out of the main body along the upper end face of the first end, and the supporting body extends out of the main body along the lower end face of the first end. The height between the lower part of the biting body and the upper part of the supporting body matches the height of the snap-fit ​​shell.

[0007] In the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model, the length of the main body extending from the lower end face of the first end of the interlocking body matches the thickness of the vertical edge of the snap-fit ​​shell.

[0008] In the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model, the length of the outer side of the biting body is greater than the length of the inner side, and the inner side is the side where the biting body is connected to the end face where the first end is located.

[0009] In the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model, the front end of the support body is rounded.

[0010] In the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model, the weighing connection part is a boss protruding from the end face where the second end is located.

[0011] In the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model, a circular through hole is provided in the center of the weighing connection part along the direction parallel to the end face where the second end is located.

[0012] In the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model, the ratio of the horizontal distance between the front end of the interlocking body and the front end of the support body to the horizontal distance between the front end of the support body and the circular through hole is 10:1.

[0013] In the multi-functional shell disassembly tool for snap-fit ​​shells provided by this utility model, the multi-functional shell disassembly tool is integrally molded from POM material.

[0014] The multi-functional shell disassembly tool for snap-fit ​​shells provided by this utility model has the following beneficial effects: When used as a shell disassembly tool in the rework station, the multi-functional shell disassembly tool provided by this utility model only requires holding the main body, aligning the snap-fit ​​part of the shell opening part with the narrow edge of the product shell, placing the support body at the bottom of the product shell, pushing the vertical surface between the snap-fit ​​part and the support body until it is close to the vertical edge of the shell, and then slowly prying open the shell, repeating this process multiple times around the shell until the shell separates from its mating part; when measuring the tripping force value, simply connect a professional push-pull force testing device to the weighing connection part, which can solve the defect that professional distance measuring force push-pull devices cannot directly measure narrow-edge products.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] Figure 1 The diagram shown is a structural diagram of a multifunctional shell disassembly tool for snap-fit ​​shells provided in an embodiment of the present invention; Figure 2 The diagram shown illustrates the use of a multi-functional shell disassembly tool for snap-fit ​​shells according to an embodiment of this utility model. Figure 1 and Figure 2As shown, the multifunctional shell disassembly tool for snap-fit ​​shells provided by this utility model includes a rectangular main body 100, a shell opening portion 200, and a weighing connection portion 300. The shell opening portion 200 and the weighing connection portion 300 are respectively disposed at a first end 110 of the main body 100 and a second end 120 opposite to the first end 100. The shell opening portion 200 includes a biting body 210 and a supporting body 220. The biting body 210 extends out of the main body 100 along the upper end face of the first end 110, and the supporting body 220 extends out of the main body 100 along the lower end face of the first end 110. The height between the lower part of the biting body 210 and the upper part of the supporting body 220 matches the height of the snap-fit ​​shell. In this embodiment, the biting body extends out along the upper end face of the first end 110 of the tool, forming a slender and sharp structure. Its main function is to engage with the narrow edge of the outer shell, allowing the tool to firmly grip the shell and prevent it from slipping or loosening during disassembly. The support body extends from the lower end face of the first end of the main body. The support body is designed to be relatively thick and robust; its main function is to support the bottom of the shell, ensuring it is not damaged during disassembly and providing sufficient stability. During use, a space is formed between the engaging body and the support body, which perfectly accommodates the shell. The narrow edge of the shell engages with the engaging body, while the bottom of the shell is secured by the support body. Through the vertical surface between the engaging body and the support body, the user can easily separate the shell from its mating part. In practice, the tool needs to be slowly pushed open, and disassembly repeated several times around the shell until the shell is completely separated from the mating part.

[0022] In this embodiment, the opening height of the tool is matched to the height of the snap-fit ​​housing to be disassembled, and is slightly greater than the design height of the snap-fit ​​housing. During disassembly, if the tool's opening height is exactly equal to the housing's height, it may cause operational inconvenience, especially when the housing has slight dimensional differences, making it difficult for the tool to insert smoothly. Therefore, a design slightly larger than the housing provides flexibility to adapt to different housing sizes. The slightly larger opening height provides a small margin during disassembly. This slight excess height prevents the tool from getting stuck or not gripping tightly during disassembly, avoiding additional friction or jamming caused by tight fit. Therefore, a tool opening height slightly greater than the housing's height helps to smoothly grip the housing during disassembly, thus accurately completing the disassembly operation. The tool's gripping part will not cause difficulty or damage to the housing due to excessive tightness. This ensures that during use, the tool can accurately grip the housing without being too tight, making the entire operation simpler, faster, and safer.

[0023] Figure 3The image shown is a detailed view of the engagement part of a multifunctional shell disassembly tool for snap-fit ​​shells according to an embodiment of the present invention. Figure 3 As shown, the length of the main body 100 extending from the lower end face of the first end 110 of the bite body 210 matches the thickness of the vertical edge of the snap-fit ​​housing. The length of the outer side of the bite body 210 is greater than the length of the inner side, and the inner side is the side where the bite body 210 connects to the end face of the first end 110. In this embodiment, the extension length of the bite body matches the thickness of the vertical edge of the housing and is slightly less than the thickness of the vertical edge of the housing. This design helps ensure that the bite body can smoothly embed into the edge of the housing during disassembly, without biting too deeply or scratching the inner layer of the housing. In particular, it avoids the bite body directly contacting the screen glass part of the housing, thereby reducing the potential risk of damage to the screen. At the same time, the length of the outer side of the bite body is greater than the length of the inner side, which allows the tool to make full contact with the narrow edge of the housing during disassembly. When the tool rotates, the height of the outer part is slightly higher than the inner part, which ensures that the tool will not deviate or make uneven contact with the housing during disassembly, thereby ensuring the stability and accuracy of the entire disassembly operation.

[0024] Specifically, in one embodiment of this utility model, the front end of the support body 220 is rounded. The rounded corner design at the front end of the support body allows the tool to provide smooth and uniform support during disassembly, avoiding direct contact between sharp angles and the outer shell, and effectively preventing scratches or damage to the product surface during disassembly.

[0025] Specifically, in one embodiment of this utility model, the weighing connection part 300 is a boss protruding from the end face of the second end 120. A circular through hole 310 extending through the entire length of the weighing connection part 300 is formed at its internal center along a direction parallel to the end face of the second end 120. In this embodiment, the weighing connection part is a boss located on the end face of the tool's second end. This protruding design allows the weighing connection part to be securely installed in a specific position and provides an ideal contact point for connecting other testing equipment. The stepped design of this part ensures that the connection part possesses sufficient strength and stability while effectively engaging with testing equipment, ensuring a tight fit. The circular through hole extending through the entire length of the connection part at its internal center not only increases the versatility of the weighing connection part but also allows it to be used with other tools or equipment (such as rope pulling). The weighing connection part is an adapter specifically designed for use with professional push-pull force testing equipment, perfectly matching professional equipment and ensuring that the tool can accurately measure force values. Through this design, the tool can be used in professional testing environments, greatly expanding its application range. Since force measurement is performed using specialized equipment, the tool's weighing connection ensures a stable connection during push-pull force testing, achieving test accuracy through precise measurement. The tool's weighing connection also features unique adaptability (such as rope threading via a circular through-hole), allowing it to fit into confined spaces. This ensures the tool can smoothly connect to narrow-sided products during testing, solving the previous problem of measurement limitations under specific conditions.

[0026] In this embodiment, the design of the weighing connection not only improves the accuracy of the tool in force measurement but also enhances its compatibility with professional equipment. Through its stepped appearance, circular through-hole, and special adaptability, the tool effectively solves the problems traditional equipment faces when measuring narrow-sided products, ensuring a stable and safe measurement process.

[0027] Specifically, in one embodiment of this utility model, the rounded corner portion of the support body serves as the fulcrum of the lever arm. The tool is a cuboid, and its length is determined by the number of lever arms. The horizontal straight-line distance between the front end of the engagement body and the fulcrum at the front end of the support body constitutes the resistance arm, while the distance from the fulcrum to the circular hole of the weighing connection is the power arm. The design ratio of the power arm to the resistance arm length is 10:1. That is, the ratio of the horizontal distance between the front end of the engagement body 210 and the front end of the support body 220 to the horizontal distance between the front end of the support body 220 and the circular through hole 310 is 10:1.

[0028] Specifically, in one embodiment of this utility model, the multifunctional shell disassembly tool is integrally molded from POM material. Snap-fit ​​shells typically have a thin wall, limiting the space available for interlocking. Therefore, this tool is made of POM material. POM, commonly known as acetal, is a linear polymer with no side chains, high density, and high crystallinity. Its molecular structure consists of repeating oxygen atoms and methyl groups, linked by covalent bonds to form polymer chains. POM possesses excellent comprehensive properties, including high strength, high hardness, and high rigidity. Its tensile strength and hardness are comparable to some metallic materials, making it suitable for components subjected to heavy mechanical loads. Furthermore, POM exhibits good wear resistance and impact resistance, remaining stable under high temperatures and frequent friction. Using this material to manufacture this tool allows for strong interlocking force without damaging the product's appearance.

[0029] The multifunctional shell disassembly tool provided by this utility model, when used as a shell disassembly tool in the rework station, simply hold the main body, align the interlocking body of the shell opening part with the narrow edge of the product shell, place the support body at the bottom of the product shell, push the vertical surface between the interlocking body and the support body until it is close to the vertical edge of the shell, and then slowly pry open the shell, repeating this process multiple times around the shell until the shell and its mating body separate. When measuring the tripping force value, simply connect a professional push-pull force testing device to the weighing connection part, which can solve the defect that professional distance measuring force push-pull devices cannot directly measure narrow-edge products.
