An embodiment of the present application provides a feeler gauge with replaceable feeler gauge pieces. The detailed descriptions will be given below.

Please refer to FIGS. 1-3, FIG. 1 is a schematic structural diagram of a feeler gauge with replaceable feeler gauge pieces provided by an embodiment of the present application, and FIG. 2 is a partial cross-sectional structural schematic diagram of the seat body and the feeler gauge piece at A-A in FIG. 1 3 is a partial cross-sectional structural schematic diagram of the seat body, the telescopic mechanism and the feeler gauge sheet at A-A in FIG. 1 . The feeler gauge 10 includes a base body 11 , a telescopic mechanism 12 and a feeler gauge piece 13 , and the feeler gauge piece 13 is detachably connected to the base body 11 .

The first limiting hole 111 and the accommodating hole 112 are sequentially opened from the surface of the base body 11 inward along the axial direction of the base body 11 , and the first limiting hole 111 is communicated with the accommodating hole 112 .

The telescopic mechanism 12 includes an elastic member 121 and a ball 122 disposed in the accommodating hole 112 . The ball 122 is in contact with the elastic member 121 and the ball 122 is snapped into the first limiting hole 111 .

One end of the feeler gauge piece 13 is provided with a second limiting hole 131 corresponding to the first limiting hole 111 , and the ball 122 can be snapped into or moved out of the second limiting hole 131 by the elastic force of the elastic member 121 . When the sheet 13 is installed on the seat body 11 , the balls 122 are locked into the first limiting hole 111 and the second limiting hole 131 at the same time.

The terms "first", "second" and "third" in this application are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature defined as "first", "second", "third" may expressly or implicitly include at least one of that feature.

Wherein, the elastic member 121 may be a spring, an elastic ring, or other device with certain elasticity. The function of the elastic member 121 is to push the ball 122 to move up and down. In this embodiment, the elastic member 121 is a spring as an example.

The base body 11 may be provided with a plurality of first limiting holes 111 and a plurality of accommodating holes 112 , and the first limiting holes 111 and the accommodating holes 112 are in one-to-one correspondence and communicate with each other. When the accommodating hole 112 is a blind hole, one end of the elastic member 121 is fixed at the bottom of the accommodating hole 112 , and the other end of the elastic member 121 away from the bottom of the accommodating hole 112 is in contact with the ball 122 .

It can be understood that the balls 122 are spheres. In order to prevent the balls 122 from sliding out of the first limit holes 111 , the diameter of the first limit holes 111 should be smaller than the diameter of the balls 122 , and the balls 122 partially protrude from the first limit holes 111 . .

When the feeler gauge piece 13 is installed on the seat body 11 , the ball 122 can be locked into the first limit hole 111 and the first limit hole 111 at the same time. In the two limiting holes 131 , the feeler gauge piece 13 is fixed on the base body 11 .

Specifically, the working process of the ball 122 being stuck into the second limiting hole 131 by the elastic force of the elastic member 121 is as follows: when the feeler piece 13 is inserted into the seat body 11, the outer wall of the feeler piece 13 contacts the ball 122, and the feeler piece 13 If the movement continues, the outer wall of the feeler gauge piece 13 will push the ball 122, thereby compressing the elastic member 121. Due to the pushing force of the feeler gauge piece 13, the ball 122 and the elastic member 121 move to the bottom of the accommodating hole 112 until the ball 122 and the elastic member 121 are compressed into the first limiting hole 111 and the accommodating hole 112 . When the second limiting hole 131 of the feeler gauge piece 13 is aligned with the first limiting hole 111 of the base body 11 , the ball 122 is no longer subjected to the pressing force of the feeler gauge piece 13 , and under the action of the restoring force of the elastic member 121 , The elastic member 121 and the balls 122 move toward the feeler gauge piece 13 until some of the balls 122 are pushed into the second limiting hole 131 , and the feeler gauge piece 13 and the base body 11 are locked together to complete the installation.

The working process of the ball 122 moving out of the second limiting hole 131 by the elastic force of the elastic member 121 is as follows: when the feeler piece 13 is pulled, the outer wall of the feeler piece 13 contacts the ball 122, and the feeler piece 13 continues to move, the feeler piece The outer wall of 13 will push the balls 122, thereby compressing the elastic members 121. Due to the pushing force of the feeler gauge 13, the balls 122 and the elastic members 121 move to the bottom of the accommodating holes 112 until the balls 122 and the elastic members 121 are compressed to In the first limiting hole 111 and the accommodating hole 112, the feeler gauge piece 13 is separated from the base body 11, and the disassembly is completed.

The ball 122 can be snapped into or moved out of the second limiting hole 131 by the elastic force of the elastic member 121, thereby realizing the installation and removal of the feeler gauge piece 13. The advantage of the feeler gauge 10 is that a severely worn feeler gauge piece 13 can be replaced independently without replacing the entire feeler gauge 10 , which is convenient for inspectors to use and reduces the overall use cost of the feeler gauge 10 .

In one embodiment, the feeler gauge piece 13 is provided with a colored protective layer. When the colored protective layer is worn, it is marked that the thickness of the feeler gauge blade 13 changes.

Specifically, when using the above-mentioned feeler gauge piece 13 to measure an electronic product, it should be checked first whether the colored protective layer in the feeler gauge piece 13 has been worn. The worn feeler gauge piece 13 has a mark visible to the naked eye, and it is checked whether the feeler gauge piece 13 is worn or not. Next, if it is detected that the colored protective layer has been worn, and the color of the feeler gauge piece 13 itself appears due to the exposure of the colored protective layer in some areas, the measurement is stopped and the feeler gauge piece 13 is replaced.
