[0001] This utility model relates to the field of mobile phone mid-plate production technology, and in particular to a mobile phone mid-plate depth detection device. Background Technology
[0002] The aluminum alloy midplate is a component of a mobile phone, located between the base plate and the front plate. It is mainly used to install the circuit board and battery, and to protect the circuit board and battery when the phone is hit. In modern smartphones, the midplate plays a key structural and support role, helping to assemble the complete phone. The design of the midplate also enhances the durability of the phone during use and protects important internal components from damage, resisting the impact of accidental collisions or shocks.
[0003] Currently, when producing the mid-plate of a mobile phone, probes are needed to detect the depth of the recessed area on the mid-plate. During the detection, the probes are used for touch detection, and they can easily be damaged if the pressure is too high. Utility Model Content
[0004] In order to solve the problems of the prior art, this utility model provides a device for detecting the depth of the middle plate of a mobile phone.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A mobile phone mid-plate depth detection device includes a transparent box, a pull-out glass on the front side of the transparent box, a longitudinal electric slide rail near one edge of the inner bottom surface of the transparent box, a guide rail near the other edge of the inner bottom surface of the transparent box, a cantilever beam between the top of the longitudinal electric slide rail and the top of the guide rail, a transverse electric slide rail on the top of the cantilever beam, and a mounting component at the bottom of the transverse electric slide rail near the front edge.
[0006] Optionally, the mounting components include a hollow base, with a sensor fixed to the top surface inside the hollow base, guide grooves provided between the inner walls on both sides of the hollow base, and a slip ring provided inside the hollow base.
[0007] Optionally, guide blocks are fixed on both outer surfaces of the slip ring, and the two guide blocks are slidably engaged inside the guide groove.
[0008] Optionally, a spring is fixed to the top of the slip ring, and the top of the spring is fixed to the inner top surface of the hollow seat.
[0009] Optionally, multiple arc-shaped spring clips are fixed at equal intervals along the circumference at the bottom of the hollow seat, and locking sleeves are threadedly connected between the outer surfaces of the multiple arc-shaped spring clips.
[0010] Optionally, a sheath is provided between the inner sides of multiple arc-shaped spring clips, and a probe is provided inside the sheath, with one end of the probe penetrating into the interior of the sensor.
[0011] Optionally, a retaining ring is fixed to the outer surface of the probe, the retaining ring is located at the bottom of the sheath, and a pressure ring is fixed to the outer surface of the sheath, the top of the pressure ring and the bottom of the slip ring are in contact with each other.
[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time: 1. In this utility model, the longitudinal and transverse electric slide rails can drive the mounting assembly to move in the horizontal plane, facilitating the adjustment of the detection position. The probe is installed inside the mounting assembly through a protective sleeve, which can protect the probe when a large external force is generated during detection. During installation, the retaining ring on the probe fits against the bottom of the protective sleeve. Therefore, when the probe moves towards the hollow seat after being subjected to a large pressing force, it will drive the protective sleeve to move upward together. The pressure ring on the protective sleeve fits against the slip ring, which will cause the spring to compress. The elastic force of the spring will offset part of the downward impact force, thus achieving the protection of the probe.
[0013] 2. In this utility model, when the probe and the sheath are installed with the hollow base, the multiple arc-shaped spring clips are in the open state in the initial stage. At this time, the sheath and the pressure ring are placed inside the hollow base, and the top of the probe is inserted into the sensor. Then, the locking sleeve is rotated to make the multiple arc-shaped spring clips retract inward to clamp the sheath, so as to achieve the purpose of constraint. Attached Figure Description

Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] Example 1, such as Figure 1-5 As shown, this utility model provides a technical solution for a mobile phone mid-plate depth detection device: it includes a transparent box 1, a pull-out glass 2 on the front side of the transparent box 1, a longitudinal electric slide rail 3 near one edge of the inner bottom surface of the transparent box 1, a guide rail 6 near the other edge of the inner bottom surface of the transparent box 1, a suspension beam 4 between the top of the longitudinal electric slide rail 3 and the top of the guide rail 6, a transverse electric slide rail 5 on the top of the suspension beam 4, and an installation component near the front edge of the bottom of the transverse electric slide rail 5.
[0019] The overall effect of Embodiment 1 is that the longitudinal electric slide rail 3 and the transverse electric slide rail 5 can drive the installation assembly to move in the horizontal plane, which facilitates the adjustment of the detection position. The probe 10 is installed inside the installation assembly through the protective sleeve 11, which can protect the probe 10 when the detection generates a large external force. During installation, the retaining ring 17 on the probe 10 is in close contact with the bottom of the protective sleeve 11. Therefore, when the probe 10 moves towards the hollow seat 7 after being subjected to a large pressing force, it will drive the protective sleeve 11 to move upward together. The pressure ring 18 on the protective sleeve 11 is in close contact with the slip ring 15, which will drive the spring 16 to compress. The elastic force of the spring 16 will offset part of the downward impact force, thus achieving the protection of the probe 10.
[0020] Example 2, as Figure 1-5As shown, the mounting assembly includes a hollow base 7. A sensor 12 is fixed to the top surface of the hollow base 7. Guide grooves 13 are formed between the inner walls on both sides of the hollow base 7. A slip ring 15 is provided inside the hollow base 7. Guide blocks 14 are fixed to the outer surfaces on both sides of the slip ring 15. The two guide blocks 14 are correspondingly slidably engaged inside the guide grooves 13. A spring 16 is fixed to the top of the slip ring 15. The top of the spring 16 is fixed to the top surface of the hollow base 7. The bottom of the hollow base 7 is circumferentially... Multiple arc-shaped spring clips 8 are fixedly attached, and locking sleeves 9 are threadedly connected between the outer surfaces of the multiple arc-shaped spring clips 8. A protective sleeve 11 is provided between the inner sides of the multiple arc-shaped spring clips 8. A probe 10 is provided inside the protective sleeve 11. One end of the probe 10 penetrates into the interior of the sensor 12. A retaining ring 17 is fixed on the outer surface of the probe 10. The retaining ring 17 is located at the bottom end of the protective sleeve 11. A pressure ring 18 is fixed on the outer surface of the protective sleeve 11. The top of the pressure ring 18 is in contact with the bottom of the slip ring 15.
[0021] The effect achieved by the entire embodiment 2 is that when the probe 10 together with the sheath 11 and the hollow base 7 are installed, the multiple arc-shaped spring clips 8 are in the open state in the initial stage. At this time, the sheath 11 together with the pressure ring 18 is placed inside the hollow base 7, and the top of the probe 10 is inserted into the sensor 12. Then, the locking sleeve 9 is rotated to make the multiple arc-shaped spring clips 8 retract inward to clamp the sheath 11, so as to achieve the purpose of restraint.
[0022] Working principle: The longitudinal electric slide rail 3 and the transverse electric slide rail 5 can drive the mounting assembly to move in the horizontal plane, facilitating the adjustment of the detection position. The probe 10 is installed inside the mounting assembly via a protective sleeve 11, which protects the probe 10 when a large external force is generated during detection. During installation, the retaining ring 17 on the probe 10 fits snugly against the bottom of the protective sleeve 11. Therefore, when the probe 10 is subjected to a large pressing force and moves towards the hollow seat 7, it will drive the protective sleeve 11 upwards as well. The pressure ring 18 on the protective sleeve 11 and the slip ring 15 interact... The fit is such that the spring 16 is compressed, and the elastic force of the spring 16 offsets part of the downward impact force, thus protecting the probe 10. When the probe 10, together with the sheath 11, is installed with the hollow seat 7, the multiple arc-shaped spring clips 8 are initially in the open state. At this time, the sheath 11 and the pressure ring 18 are placed inside the hollow seat 7, and the top of the probe 10 is inserted into the sensor 12. Then, the locking sleeve 9 is rotated to make the multiple arc-shaped spring clips 8 retract inward to clamp the sheath 11, so as to achieve the purpose of restraint.
