[0002] At present, the electronic plug gauge is an electronic comparator used for high-precision inner diameter measurement. It converts the mechanical displacement into electrical quantity through the inductive sensor and displays the measured aperture digitally. The current electronic plug gauge is mainly composed of a grip, an electronic digital display head and a detection head light structure. When using the electronic plug gauge, hold the grip and insert the detection head into the part to be detected, and then the part can be detected.

[0003] Existing portable electronic plug gauges usually require the use of detection heads of special sizes when measuring larger workpieces, and the detection heads need to be frequently replaced when detecting workpieces of different sizes, which has poor practicality. In addition, when the existing electronic plug gauges are actually used, the detection heads at the ends are easily damaged by bumps. The traditional electronic plug gauges have poor protection performance for the detection heads, and the existing portable electronic plug gauges are not convenient to carry when used in practice, and often need to be placed in a box for carrying and use. Therefore, the existing portable electronic plug gauges have the disadvantages of being inconvenient to detect workpieces of different sizes, inconvenient to protect the detection heads, and inconvenient to carry.

[0032] Example 1

[0033] The utility model provides a technical solution: a portable electronic plug gauge, comprising a handle 1, the upper end of the handle 1 is fixedly connected with a digital display head 2, the outer surface of the handle 1 is provided with a button 3, the inner top wall of the lower end of the handle 1 is fixedly connected with an electric telescopic rod 4, the lower end of the handle 1 is slidably connected with a movable block 5, the end of the electric telescopic rod 4 is fixedly connected to the inner bottom wall of the movable block 5, the electric telescopic rod 4 is electrically connected to a pressure switch 10 through a wire, the outer surface of the lower end of the handle 1 is rotatably connected with a first connecting rod 6 and a second connecting rod 7 through a hinge block, and the end of the second connecting rod 7 is connected to the outer surface of a detection head 8 through a hinge block. The surface is rotatably connected, the first connecting rod 6 and the second connecting rod 7 are arranged in parallel, four of the first connecting rod 6, the second connecting rod 7 and the detection head 8 are arranged and are evenly distributed in a circular array, the end of the first connecting rod 6 is rotatably connected to the detection head 8 through a hinge block, the outer surface of the lower end of the movable block 5 is rotatably connected to the third connecting rod 9 through a hinge block, one end of the third connecting rod 9 is rotatably connected to the outer surface of the detection head 8 through a hinge block, the inner side wall of the detection head 8 is fixedly connected to a pressure switch 10, one end of the pressure switch 10 is fixedly connected to a telescopic head 11, and the outer surface of the detection head 8 is fixedly connected to a laser rangefinder 12.

[0034] In order to facilitate the detection of workpieces of different sizes, such as the attached Figures 1 to 5 As shown, the present application adopts the following structure. Through the arrangement of the electric telescopic rod 4, the movable block 5, the first connecting rod 6, the second connecting rod 7, the detection head 8 and the third connecting rod 9, the portable electronic plug gauge has the effect of facilitating the detection of workpieces of different sizes. Through the coordinated arrangement of the electric telescopic rod 4, the movable block 5, the first connecting rod 6, the second connecting rod 7, the detection head 8 and the third connecting rod 9, during use, the extension length of the electric telescopic rod 4 can be adjusted. When the electric telescopic rod 4 is extended, the third connecting rod 9 drives the four detection heads 8 to open and contract. The connecting line of the connection between the two ends of the first connecting rod 6 and the second connecting rod 7, and the center line of the first connecting rod 6 and the second connecting rod 7 form a parallelogram effect, thereby ensuring that the detection head 8 is always in a vertical state, and improving the quality of the portable electronic plug gauge. When performing inspection, hold the handle 1 and press the button 3. At this time, the telescopic rod of the electric telescopic rod 4 extends. After adjusting the opening degree of the detection head 8, when the outer surface of the detection head 8 contacts the workpiece, the inner wall of the workpiece contacts the end of the telescopic head 11, and the telescopic head 11 squeezes the pressure switch 10.

In addition, the distance between the inner side and the outermost side of the detection head 8 is the size of the workpiece, so that the opening degree of the detection head 8 can be adjusted for workpieces of different sizes to detect the workpiece, thereby achieving the purpose of facilitating the detection of workpieces of different sizes.

[0035] Example 2

[0036] The utility model provides a technical solution: the outer surface of the handle 1 is fixedly connected with a connecting seat 13, the inner side wall of the connecting seat 13 is provided with a spring 16, one end of the spring 16 is fixedly connected with the outer surface of a pressing block 14, the other end of the connecting seat 13 is fixedly connected with the inner side wall of the connecting seat 13, the inner side wall of the connecting seat 13 is slidably connected with the pressing block 14, the outer surface of the pressing block 14 is fixedly connected with a limiting rod 15, the lower end of the connecting seat 13 is threadedly connected with a protective shell 17, the inner side wall of the protective shell 17 is provided with a limiting groove 18, a plurality of limiting grooves 18 are provided and are evenly distributed in a ring array, and the end of the limiting rod 15 is clamped with the inner side wall of the limiting groove 18.

By setting the connecting seat 13, the pressing block 14, the limiting rod 15 and the protective shell 17, the portable electronic plug gauge has the effect of facilitating the protection of the detection head 8. By the coordinated setting of the connecting seat 13, the pressing block 14, the limiting rod 15 and the protective shell 17, when not in use, the four detection heads 8 can be retracted, and the upper end of the protective shell 17 can be threadedly connected to the outer surface of the lower end of the connecting seat 13. At this time, the protective shell 17 will be able to protect the detection head 8 inside it, effectively preventing the detection head 8 from being bumped. When the cover 17 is tightened, the spring 16 will pop the pressing block 14 outward, and the end of the limiting rod 15 will extend out and engage with the limiting groove 18 on the inner wall of the protective shell 17. The end of the limiting rod 15 is inclined, so that the protective shell 17 can only be tightened and cannot be rotated in the opposite direction. When it needs to be opened, the outer surface of the pressing block 14 is pressed to drive the limiting rod 15 to retract into the inside of the connecting seat 13, so that the end of the limiting rod 15 is separated from the engagement of the limiting groove 18, and the interface unscrews the protective shell 17 from the lower end of the connecting seat 13, thereby achieving the purpose of facilitating the protection of the detection head 8.

[0040] In order to make it easier to carry, Figures 1 to 3 , Fig. 9and Fig.10 As shown, the present application adopts the following structure. Through the arrangement of the hanging rope storage shell 19, the rope winding roller 21, the hanging rope 22 and the button 3, the portable electronic plug gauge has the effect of being more convenient to carry. Through the coordinated arrangement of the rope winding roller 21, the hanging rope 22 and the coil spring 23, during use, the hanging rope 22 is wound around the outer surface of the rope winding roller 21, and the elastic force of the coil spring 23 makes the rope winding roller 21 have a rotational torque. In actual use, the hanging rope 22 can be stretched and the length of the hanging rope 22 can be freely changed. The hanging rope 22 can be hung on the shoulder or neck for carrying. When the hanging rope 22 is not in use, the coil spring 23 drives the rope winding roller 21 to rotate, and then the hanging rope 22 is wound around the outer surface of the rope winding roller 21 and is collected into the interior of the hanging rope storage shell 19, thereby achieving the purpose of being more convenient to carry.
