Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 13 , describing the embodiments of the present utility model.

[0035] According to an embodiment of the present invention, a groove measuring jig for an electronic device is provided, comprising a workbench 1, a digital display 2, a guide member 3, and a mold core 4 disposed on the workbench 1. The digital display 2 comprises a digital display body 21 and a stylus 22 that is retractable along a first direction, the digital display body 21 being used to display data of the retractable stroke of the stylus 22; the guide member 3 comprises a guide block 31 and a guide channel extending through the guide block 31 along the first direction, the stylus 22 being slidably disposed within the guide channel, the front end of the stylus 22 being adapted to pass through the guide channel and extend into a groove 91 of a product 9 to be measured; the mold core 4 is slidably connected to the workbench 1 along the first direction, and comprises a positioning structure 41, the positioning structure 41 being used to secure the product 9 to be measured and position the groove 91 of the product 9 to be measured on the retractable path of the stylus 22.

[0036] In the groove measuring jig for electronic equipment provided by the embodiment of the present utility model, the stylus 22 of the digital display 2 can be extended and retracted relative to the digital display body 21, and the data of the extension and retraction stroke of the stylus 22 is displayed by the digital display 2, that is, the depth of the groove 91 of the product to be tested can be known based on the extension and retraction stroke of the stylus 22. The stylus 22 can be slidably inserted into the guide channel of the guide member 3, and can slide along the guide channel to improve the accuracy of the test of the stylus 22. The product to be tested 9 can be fixed thereon by the mold core 4 and its positioning structure 41, and since the groove 91 of the product to be tested 9 is located on the extension and retraction path of the stylus 22, after the stylus 22 extends out of the guide channel of the guide member 3, it can be inserted into the groove 91 of the product to be tested 9, so that it is blocked by the groove 91 and cannot be extended further. At this time, the data displayed on the digital display 2 can reflect the depth of the groove 91 of the product to be tested 9.

[0037] Compared with manual depth measurement using a micrometer, the groove measuring jig for electronic devices provided by the embodiment of the present invention only requires assembling the product 9 to be measured on the model, inserting the stylus 22 into and pressing against the groove 91 of the product 9 to be measured, and then measuring the depth of the groove 91. This is easy to operate, saves time and effort, and can effectively improve the measurement efficiency of the groove 91 of the electronic device.

[0038] For ease of explanation, the structure and usage of the groove measuring jig of an electronic device are described in detail by taking the measurement of the depth of the card tray of a mobile phone as an example.

[0039] Among them, such as Figure 2 As shown, the first direction is the direction indicated by X. In this embodiment, on the workbench 1, the digital display 2, the guide member 3 and the mold core 4 are arranged in sequence along the first direction.

[0040] In some embodiments, a plug-in portion 221 is provided at the front end of the measuring needle 22 . The structure of the plug-in portion 221 is adapted to the structure of the groove 91 of the product to be measured 9 , and the structure of the guide channel is adapted to the structure of the plug-in portion 221 .

[0041] Specifically, the front end of the stylus 22 refers to the free end of the stylus 22. By providing a plug-in portion 221 at the front end of the stylus 22, and by adapting the plug-in portion 221 to the groove 91 of the product 9 to be tested, and the plug-in portion 221 to the guide channel, when the plug-in portion 221 of the stylus 22 is inserted into the groove 91 of the product 9 to be tested, a mutually restraining relationship is formed between the plug-in portion 221 and the groove 91 of the product 9 to be tested, thereby improving the accuracy of the dimensional measurement of the groove 91 of the product 9 to be tested.

[0042] In some embodiments, the rear end of the measuring needle 22 is connected to an elastic member 5 , and the elastic member 5 is suitable for applying an elastic force along a first direction to the measuring needle 22 .

[0043] By connecting the elastic member 5 to the rear end of the measuring needle 22, after the product 9 to be measured is assembled on the mold core 4, the measuring needle 22 can automatically extend out of the guide channel of the guide member 3 under the elastic force of the elastic member 5, be inserted into the groove 91 of the product to be measured 9, and abut against the groove 91, thereby improving the efficiency and measurement accuracy of the groove 91.

[0044] Specifically, in some embodiments, Figure 13 As shown, the elastic member 5 includes a spring, which is sleeved on the measuring needle and abuts between the measuring needle 22 and the positioning seat 7. When the measuring needle 22 moves in the opposite direction of X, the spring is compressed. The spring can provide the measuring needle 22 with an elastic force along the X direction, so that the plug-in portion 221 of the measuring needle 22 can be automatically inserted into the groove 91 of the product to be measured 9.

[0045] In some embodiments, the guide member 3 is further provided with an anti-falling structure 6 for preventing the measuring needle 22 from falling out of the guide channel.

[0046] By providing the anti-slip structure 6 in the guide channel of the guide member 3 , the measuring needle 22 can be prevented from slipping out of the guide channel, thereby improving the convenience of the groove measuring jig of the electronic device in measuring the groove 91 of the product to be measured 9 .

[0047] In some embodiments, reference Figures 10 to 12The anti-slip structure 6 includes a limiting rod 61, which is set at an angle to the guide channel. The limiting rod 61 passes through the guide channel, and the plug-in portion 221 is provided with a limiting groove 62 set along the first direction, and the limiting rod 61 is located in the limiting groove 62.

[0048] Specifically, by providing a limiting groove 62 in the plug-in portion 221 and a limiting rod 61 in the limiting groove 62, a limit is formed between the limiting groove 62 and the limiting rod 61, which can prevent the plug-in portion 221 from slipping out of the guide channel of the guide member 3. The length of the limiting groove 62 is the maximum telescopic stroke of the plug-in portion 221, and the length of the limiting groove 62 is determined according to needs.

[0049] In this embodiment, the limiting groove 62 passes through the inserting portion 221 , the guide block 31 is provided with a through hole, the through hole is communicated with the limiting groove 62 , the limiting rod 61 is inserted into the through hole and passes through the limiting groove 62 .

[0050] Of course, the anti-slip structure 6 may also be in other forms, as long as it can prevent the plug-in portion 221 from slipping out of the guide channel.

[0051] In some embodiments, a positioning seat 7 is further included. The positioning seat 7 is located between the digital display 2 and the guide member 3. The positioning seat 7 has a positioning channel extending along the first direction. The measuring needle 22 is led out from the digital display body 21, passes through the positioning channel, and then slides and plugs into the guide channel.

[0052] Since the length of the stylus 22 is relatively large, a positioning seat 7 is provided between the digital display 2 and the guide member 3. The stylus 22 passes through the positioning channel of the positioning seat 7, which can position the stylus 22, further improve the stability of the telescopic stroke of the stylus 22, and improve the accuracy of the measuring fixture in measuring the size of the groove 91 of the product 9 to be measured.

[0053] In some embodiments, a sliding guide structure 8 is further included, and the mold core 4 is slidably connected to the workbench 1 through the sliding guide structure 8; a positioning surface 32 is provided on the side of the guide member 3 facing the mold core 4; the mold core 4 has a measuring position and an avoidance position. In the measuring position, the side wall of the groove 91 of the product to be measured 9 on the mold core 4 is located and abuts against the positioning surface 32 of the guide member 3; in the avoidance position, the mold core 4 is away from the measuring needle 22.

[0054] By setting up a sliding guide structure 8, the mold core 4 is connected to the workbench 1 through the sliding guide structure 8, so that the mold core 4 can move along the sliding guide structure 8, and the mold core 4 can drive the product to be measured 9 thereon to approach or move away from the measuring needle 22 along the first direction, thereby improving the convenience of operation of the measuring fixture.

[0055] Before measurement, the mold core 4 is first moved to the avoidance position. At this time, it is convenient to assemble the product 9 to be measured with the mold core 4 and fix the product 9 to be measured.

[0056] Afterwards, the mold core 4 is moved, and the mold core 4 drives the product to be tested 9 to the measuring position, so that the side wall of the groove 91 of the product to be tested 9 is in contact with the positioning surface 32 of the guide member 3. Then, the plug-in portion 221 of the measuring needle 22 extends out of the guide channel of the guide member 3 and is inserted into the groove 91 of the product to be tested 9. The digital display 2 displays the extension stroke data of the measuring needle 22, thereby accurately measuring the depth of the groove 91 of the product to be tested 9. In this embodiment, the card tray depth of the mobile phone is accurately measured.

[0057] Specifically, the digital display 2 can be reset to zero when the front end surface of the plug-in part 221 is flush with the positioning surface 32 of the guide member 3. Thus, when the side wall of the mobile phone where the card tray is located abuts against the positioning surface 32 of the guide member 3, the plug-in part 221 is fully inserted into the card tray. At this time, the reading of the digital display 2 is the depth of the card tray, that is, the measurement efficiency is further improved.

[0058] In some embodiments, the sliding guide structure 8 includes a slide rail 81 arranged along the first direction and a slider 82 arranged on the slide rail 81 , and the mold core 4 is connected to the slider 82 .

[0059] The sliding guide structure 8 adopts a slide rail 81 and a slider 82, has a simple structure, and is easy to assemble and operate.

[0060] In some embodiments, the positioning structure 41 includes a plurality of positioning screws, and the plurality of positioning screws are adapted to cooperate with a plurality of positioning holes of the product to be tested 9 .

[0061] Specifically, when assembling the product to be tested 9 , the multiple positioning holes of the product to be tested 9 are matched one by one with the multiple positioning screws on the mold core 4 , the positioning screws pass through the positioning holes, and are tightened to achieve assembly and positioning of the product to be tested 9 .

[0062] In some embodiments, the recess 91 of the electronic device includes a card tray for a mobile phone.

[0063] The specific measurement method is as follows:

[0064] Move the mold core 4 to the avoidance position and place the mobile phone into the mold core 4 and fix it;

[0065] Move the mold core 4 to the measuring position. At this time, the side wall of the mobile phone where the card tray is located abuts against the positioning surface 32 of the guide member 3.

[0066] The plug-in portion 221 of the stylus 22 extends out of the guide channel of the guide member 3 and is inserted into the card holder of the mobile phone. The value displayed on the dial through the sensor calculation in the digital display 2 is the depth dimension measured by the card holder.
