[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] As attached Figure 1 To be continued Figure 6 As shown:

[0024] Example 1: This utility model provides a PC component quality inspection device, including a setting component 1 and a measuring component 2. The setting component 1 includes a scale seat 101, an adjusting screw 102, a positioning seat 103, and a zero-position abutment 104. The adjusting screw 102 is rotatably connected inside the scale seat 101, and the positioning seat 103 is inserted into the scale seat 101. The adjusting screw 102 is screwed into the positioning seat 103 through a rod thread, and the zero-position abutment 104 is fixedly installed at the bottom of the scale seat 101. The measuring component 2 includes a movable abutment 201 and an indicator block 202. The movable abutment 201 is inserted into the scale seat 101, and the indicator block 202 is inserted into the top of the movable abutment 201 and also into the scale seat 101.

[0025] In this embodiment, the scale base 101 has a measuring scale 1012 on its side, and the movable abutment 201 has a pointer b2011 on its side that indicates the distance between the zero position abutment 104 and the movable abutment 201. In use, the measuring scale 1012 can be used to measure and inspect the dimensional parameters of the PC component. That is, the dimensional parameters of the PC component can be measured in free mode. After the zero position abutment 104 and the movable abutment 201 are respectively placed against the two sides of the PC component to be measured, the dimensional parameters of the PC component can be known by observing and reading the indication value of the pointer b2011 on the measuring scale 1012. Thus, it can be determined whether the PC component is compliant and qualified. The measurement is convenient and easy to use.

[0026] In this embodiment, the positioning base 103 has a setting groove on its side, which consists of an inverted "V"-shaped indicator groove 1032 and two linearly arranged guide grooves 1031. The two linearly arranged guide grooves 1031 are respectively connected to the two side grooves of the indicator groove 1032. The bottom of the indicator block 202 has a hidden tension spring 2021, and the two ends of the hidden tension spring 2021 are respectively fixedly connected to the inside of the indicator block 202 and the inside of the moving abutment 201. The side of the indicator block 202 has a display guide rod 2022. When the display guide rod 2022 is in the groove plane of the guide groove 1031, the top block of the indicator block 202 is hidden inside the scale base 101, and the guide groove 1031 is located in the direction of the indicator. The indicator block 202 follows the movement path of the movable abutment 201. In use, the fixed value mode can quickly determine whether the dimensional parameters of the PC component meet the specified values ​​through the positioning scale 1011. When the adjusting screw 102 is rotated, the adjusting screw 102 can drive the positioning seat 103 to change its position through the screw thread, that is, change the position of the highest point of the indicator groove 1032. This position is the set value. The top of the scale seat 101 is provided with the positioning scale 1011, and the positioning seat 103 is provided with a pointer a1033 indicating the position of the positioning scale 1011. The positioning scale 1011 indicates the distance between the zero position abutment 104 and the highest point of the indicator groove 1032. This distance can be determined by the pointer a1033. The needle a1033 is precisely adjusted on the positioning scale 1011. After adjustment, the PC component can be inspected. During the operation of placing the zero-position abutment 104 and the moving abutment 201 against the two sides of the PC component to be tested, the moving abutment 201 will drive the indicator block 202 to move synchronously. During the movement, the indicator block 202 will pass through or enter the interior of the setting groove. After the zero-position abutment 104 and the moving abutment 201 against the two sides of the PC component to be tested, if the display guide rod 2022 passes through the guide groove 1031 and enters the interior of the indicator groove 1032 and is at the highest point of the indicator groove 1032, then the indicator groove 1032 guides and supports the display guide rod 2022. Under the action of the support, the top block of the indicator block 202 will protrude from the interior of the scale seat 101 and stretch the hidden tension spring 2021, thereby driving the measured value and the set value. When the display guide rod 2022 is in one of the three states: not in the highest point of the indicator groove 1032, in the inlet groove 1031, or not in the set groove, the indicator block 202 will always be hidden inside the scale seat 101 under the action of the hidden tension spring 2021. Therefore, by judging whether the indicator block 202 protrudes from the scale seat 101, it can be determined whether the dimensional parameters of the PC component are qualified. There is no need to read the measured value. It is suitable for rapid quality inspection of large batches of PC components of the same specification. It is convenient and flexible to use.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In this invention, the dimensional parameters of PC components can be measured and inspected using the measuring scale 1012. Specifically, the dimensional parameters of the PC component are measured in free mode. By placing the zero-position abutment 104 and the movable abutment 201 against both sides of the PC component to be measured, the dimensional parameters of the PC component can be determined by observing and reading the indication value of the pointer b2011 on the measuring scale 1012. This allows for the determination of whether the PC component meets the specified standards. The measurement is convenient. In fixed-value mode, the positioning scale 1011 enables quick determination of whether the dimensional parameters of the PC component meet the specified values. When the adjusting screw 102 is rotated, the adjusting screw 102 can drive the positioning seat 103 to change its position via the screw thread, thus changing the position of the highest point of the indicating groove 1032. This position is the set value, which can be precisely adjusted by the indication value of the pointer a1033 on the positioning scale 1011. After adjustment, the PC component can be inspected. The operation involves placing the zero-position abutment 104 and the movable abutment 201 against both sides of the PC component to be measured. In the process, the movable abutment 201 will drive the indicator block 202 to move synchronously. During the movement, the indicator block 202 will pass through or enter the interior of the setting groove. After the zero position abutment 104 and the movable abutment 201 respectively abut against the two sides of the PC component to be measured, if the display guide rod 2022 passes through the guide groove 1031 and enters the interior of the indicator groove 1032 and is at the highest point of the indicator groove 1032, at this time, under the guiding and supporting effect of the indicator groove 1032 on the display guide rod 2022, the top block of the indicator block 202 will protrude from the scale seat 101. The hidden tension spring 2021 is stretched inside the platen and extends inside the platen, thereby driving the measured value and the set value. When the display guide rod 2022 is in one of the three states: not in the highest point of the indicator groove 1032, in the guide groove 1031, or not in the set groove, the indicator block 202 will always be hidden inside the scale seat 101 under the action of the hidden tension spring 2021. Therefore, by judging whether the indicator block 202 protrudes from the scale seat 101, it can be determined whether the dimensional parameters of the PC component are qualified, without the need to read the measured value.
