[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example

[0021] For auxiliary dimensional measuring devices, please refer to [reference needed]. Figures 1-4 The dimension auxiliary measuring device provided by this utility model mainly consists of two parts: a measuring base 1 and a positioning component.

[0022] The measuring base 1 provides stable support and an operating platform for the entire device, and its top is equipped with a measuring motherboard 3 that is adapted to the laptop keyboard case 100. The shape and size of the measuring motherboard 3 are precisely matched to the laptop keyboard case 100 to be measured, ensuring accurate placement of the keyboard case during the measurement process. The top of the measuring motherboard 3 has at least two positioning slots, the positions and sizes of which correspond to specific locations on the laptop keyboard case 100 for subsequent installation of positioning components.

[0023] The positioning component includes a square positioning block 4 that fits into the laptop keyboard slot 101. The square positioning block 4 is precisely designed to fit snugly into the positioning slots of the laptop keyboard slot 101 and the measuring motherboard platform 3, thereby achieving precise positioning of the laptop keyboard case 100. The bottom of the measuring motherboard platform 3 has a protrusion 31 that fits into the groove of the laptop keyboard case 100. When the laptop keyboard case 100 is placed on the measuring motherboard platform 3, the protrusion 31 will accurately embed into the groove of the keyboard case, further enhancing the stability of the keyboard case during the measurement process.

[0024] As a further optimization of the above technical solution, the square positioning block 4 is made of magnetic material, while the positioning groove is made of iron. This material selection utilizes the magnetic attraction between magnets and iron; when the square positioning block 4 is inserted into the positioning groove, the magnetic force will cause the two to be tightly connected. This connection method not only enhances the stability of the connection and effectively avoids the square positioning block 4 from shaking or shifting during measurement, but also makes the installation and removal of the square positioning block 4 more convenient and quick, improving the efficiency of the measurement operation.

[0025] A U-shaped limiting plate 41 is provided on the outer side of the square positioning block 4. The shape of the U-shaped limiting plate 41 matches the outer contour of the square positioning block 4, and its size is carefully adjusted so that when the square positioning block 4 is inserted into the positioning groove, the bottom surface of the U-shaped limiting plate 41 can contact the top surface of the laptop keyboard shell 100. The main function of the U-shaped limiting plate 41 is to limit the laptop keyboard shell 100 in the vertical direction, preventing it from moving up and down or tilting during measurement. Through this limiting function, it is ensured that the laptop keyboard shell 100 remains in a stable position during measurement, providing a reliable guarantee for accurate measurement.

[0026] Support legs 2 are provided on both sides of the bottom of the measuring base 1. The height and strength of the support legs 2 are reasonably designed to provide stable support for the measuring base 1. When the measuring device is placed on the workbench, the support legs 2 are in full contact with the workbench surface, so that the measuring base 1 can remain level and stable, avoiding the measuring device from shaking due to uneven contact between the bottom of the measuring base 1 and the workbench, thus affecting the accuracy of the measurement results.

[0027] Specifically, the measuring motherboard platform 3 can be tightly connected to the top of the measuring base 1 through an integrated molding process. This connection method ensures the structural stability and integrity between the measuring motherboard platform 3 and the measuring base 1, and avoids loosening or displacement during use.

[0028] The square positioning block 4 and the positioning groove are connected by a plug-in connection. When the square positioning block 4 is inserted into the positioning groove, since the square positioning block 4 is made of magnetic material and the positioning groove is made of iron material, a magnetic attraction will be generated between the two, so that the square positioning block 4 can be firmly fixed in the positioning groove. At the same time, the bottom periphery of the square positioning block 4 fits tightly against the inner side of the positioning groove, further ensuring the stability and accuracy of the connection.

[0029] The spiral-shaped limiting plate 41 is firmly connected to the outer side of the square positioning block 4 by welding. This connection method allows the spiral-shaped limiting plate 41 to form an integral whole with the square positioning block 4, ensuring that the spiral-shaped limiting plate 41 can effectively perform its limiting function during the measurement process.

[0030] The support leg 2 is fixed to the bottom sides of the measuring base 1 by bolts. This connection method facilitates the installation and removal of the support leg 2, while also ensuring the connection strength between the support leg 2 and the measuring base 1, thus ensuring the stability of the measuring device during use.

[0031] When measuring the dimensions of the laptop keyboard case 100, carefully place the laptop keyboard case 100 on the measuring motherboard platform 3, ensuring that the protrusion 31 on the bottom of the measuring motherboard platform 3 accurately engages with the groove in the laptop keyboard case 100. This step is crucial to ensuring that the laptop keyboard case 100 maintains a stable position during measurement. The engagement of the protrusion 31 with the groove effectively restricts the horizontal movement of the keyboard case.

[0032] Next, the square positioning block 4 is inserted into the positioning groove. During insertion, ensure that the bottom outer edge of the square positioning block 4 is in close contact with the inner side of the positioning groove, and the top outer edge is in close contact with the inner side of the laptop keyboard groove 101. Since the square positioning block 4 is made of magnetic material and the positioning groove is made of iron material, a magnetic attraction will be generated between them, allowing the square positioning block 4 to be firmly fixed in the positioning groove. At the same time, the bottom end surface of the U-shaped limiting plate 41 on the outer side of the square positioning block 4 contacts the top surface of the laptop keyboard shell 100, which provides a vertical limiting effect on the laptop keyboard shell 100, preventing it from moving up and down or tilting during measurement.

[0033] After completing the above operations, the outer dimensions of the laptop keyboard case 100 can be measured. Using appropriate measuring tools, accurately measure each dimension of the keyboard case according to the prescribed measurement method, and record the measurement results.

[0034] During the measurement process, if one of the square positioning blocks 4 can be smoothly inserted into the positioning slot while the other square positioning block 4 cannot be inserted, this indicates that the dimensions of some notebook key slots 101 do not meet the standard, thus achieving the purpose of detecting the dimensions of the notebook key slots 101. Non-compliant keyboard cases should be marked and processed promptly to prevent them from entering subsequent production stages.

[0035] The above description is only a preferred embodiment of the present utility model and is 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.
