Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone mid-plate testing technology, and in particular to a mobile phone mid-plate leak detection fixture. Background Technology
[0002] The mid-plate of a mobile phone is one of the important internal components, mainly responsible for supporting and connecting various hardware components and ensuring their coordinated operation. To install screws or other fasteners, machines are typically used to machine holes and tap threads into the mid-plate. However, machines may miss or fail to tap threads, necessitating the use of a fixture to inspect the threaded holes in the mid-plate. Existing fixture inspection methods consist of a fixture body and a detection shaft. The detection shaft is usually fixed to the fixture body, making it prone to breakage. Damage to the shaft may require replacement of the entire fixture or remachining, increasing the difficulty and cost of repair. Therefore, this invention proposes a fixture for detecting missing threads in the mid-plate of a mobile phone, to solve the aforementioned technical problems. Utility Model Content
[0003] In order to overcome the technical problems mentioned in the background art, this utility model provides a mobile phone mid-plate leak detection fixture.
[0004] The technical implementation scheme of this utility model is as follows: a mobile phone mid-plate leak tapping detection fixture, including a fixture body, a bottom shell attached to the bottom surface of the fixture body, the fixture body being hollow, a support plate symmetrically slidably connected inside the fixture body, a detection shaft for detecting threaded holes and a positioning shaft for positioning the mobile phone mid-plate distributed on the support plate, a guide protrusion provided inside the fixture body, a guide groove provided on the support plate cooperating with the guide protrusion, the support plate being able to move up and down through a drive assembly, and holes provided on the fixture body for the detection shaft and the positioning shaft to move, the diameter of the detection shaft being smaller than the diameter of the threaded hole of the mobile phone mid-plate, but larger than the diameter of the guide hole of the mobile phone mid-plate.
[0005] Furthermore, the drive assembly includes symmetrically rotatably connected rotating screws within the fixture body. The rotating screws are interconnected via transmission components. Each rotating screw is threadedly connected to a corresponding bearing plate. A knob is rotatably connected within the fixture body. A first synchronous pulley is fixedly connected to the shaft of the knob, and a second synchronous pulley is fixedly connected to one of the rotating screws. The first and second synchronous pulleys are connected by a synchronous belt. One end of the knob passes through the fixture body and extends to the outside.
[0006] Furthermore, the diameter of the first synchronizing pulley is larger than the diameter of the second synchronizing pulley.
[0007] Furthermore, the corresponding support plate is provided with a movable groove.
[0008] Furthermore, the fixture body is rectangular, with chamfered corners at its four corners, recessed grooves on both sides of the middle section of the fixture body to facilitate gripping the mobile phone's midplate, and a step on the long side of the fixture body.
[0009] Furthermore, the bottom surface of the bottom shell is a smooth plane, and the recessed groove is also provided with a gripping groove to facilitate gripping the fixture body.
[0010] The present invention has the following advantages: The present invention is equipped with a knob and other components. When the fixture is not in use, the knob is rotated in the opposite direction, and the detection shaft and the positioning shaft move downwards. Then, the detection shaft and the positioning shaft retract into the fixture body, thereby playing a protective role and preventing the detection shaft and the positioning shaft from breaking due to accidents, which would require the replacement of the entire fixture.

Detailed Implementation
[0016] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0017] A type of mobile phone mid-plate leak detection fixture, such as Figures 1-4As shown, the fixture includes a rectangular jig body 101 with chamfered corners to prevent operators from being scratched by sharp corners during operation, thus improving safety. The jig body 101 has recessed grooves 1011 on both sides of its middle section for easy gripping of the phone's middle plate 201. A step 1013 is provided on the long side of the jig body 101. The combination of the step 1013 and the recessed grooves 1011 makes it easier for operators to grip and place the phone's middle plate 201 onto the jig body 101. A bottom shell 102 is attached to the bottom surface of the jig body 101. The bottom surface of the bottom shell 102 is a smooth plane. A gripping groove 1012 is also provided within the recessed grooves 1011 to facilitate gripping of the jig body 101. The gripping groove 1012 provides a good gripping point when moving the jig body 101, preventing slippage or improper operation. To prevent danger or damage, the fixture body 101 is hollow, and a support plate 103 is symmetrically slidably connected inside the fixture body 101. The support plate 103 has a detection shaft 104 for detecting threaded holes and a positioning shaft 105 for positioning the mobile phone middle plate 201. A guide protrusion 1014 is provided inside the fixture body 101, and a guide groove 1031 that cooperates with the guide protrusion 1014 is provided on the support plate 103. The support plate 103 moves up and down through a drive assembly. The fixture body 101 has holes for the detection shaft 104 and the positioning shaft 105 to move. The diameter of the detection shaft 104 is smaller than the diameter of the threaded hole of the mobile phone middle plate 201, but larger than the diameter of the guide hole of the mobile phone middle plate 201. The guide hole is a small hole drilled before thread tapping. The function of this hole is to provide a foundation for the tapping process and ensure the accuracy and quality of thread processing.
[0018] Specifically, the drive assembly includes symmetrically rotatably connected rotating screws 109 within the fixture body 101. The rotating screws 109 are interconnected via a transmission component, specifically a synchronous belt component. Two synchronous pulleys are respectively fixed to the rotating screws 109 and connected to each other via a synchronous belt. In other embodiments, a gear set can be used instead. The rotating screws 109 are threadedly connected to the corresponding support plates 103. A knob 106 is rotatably connected within the fixture body 101. A first synchronous pulley 107 is fixed to the shaft of the knob 106, and a second synchronous pulley 108 is fixed to one of the rotating screws 109. The first synchronous pulley 107 and the second synchronous pulley 108 are connected via a synchronous belt. One end of the knob 106 passes through the fixture body 101 and extends to the outside. The diameter of the first synchronous pulley 107 is larger than the diameter of the second synchronous pulley 108, which increases the torque. One of the support plates 103 is provided with a movable groove 1032 to allow the support plate 103 to move up and down.
[0019] Therefore, when the fixture is needed, rotating knob 106 causes the first synchronous pulley 107 to rotate. The first synchronous pulley 107 then drives the second synchronous pulley 108 to rotate via a synchronous belt. The rotation of the second synchronous pulley 108 drives one of the rotating screws 109 to rotate. The rotating screw 109, through a transmission component, drives the other rotating screws 109 to rotate. This rotation of the rotating screws 109 causes the support plate 103 to move upwards, allowing the detection shaft 104 and positioning shaft 105 to pass through the fixture body 101, thus enabling the inspection of the mobile phone middle plate 201. During inspection, the positioning hole of the mobile phone middle plate 201 is aligned with the positioning shaft 105, and then it is placed directly on the fixture body 101. If there is a hole without threads, it is a guide hole. Because the diameter of the guide hole is smaller than the diameter of the detection shaft 104, one end of the mobile phone middle plate 201 will be tilted and cannot be placed flat on the fixture body 101. If all holes are threaded, then... Figure 4 As shown, it can be placed flat on the fixture body 101. When the fixture is not in use, the knob 106 is rotated in the opposite direction, and the detection shaft 104 and the positioning shaft 105 move downwards. The detection shaft 104 and the positioning shaft 105 then retract into the fixture body 101, thereby playing a protective role and preventing the detection shaft 104 and the positioning shaft 105 from breaking due to accidents, which would require the replacement of the entire fixture.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
