[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1

[0032] The utility model provides a device for measuring the size of a car piston. Figure 1-Figure 3 As shown, the measuring device is a device for measuring the size of an automobile piston, comprising a ruler frame 1 and a small anvil 11 and a micrometer rod 12 symmetrically arranged on the ruler frame 1, wherein the small anvil 11 is fixedly connected to the ruler frame 1, and the micrometer rod 12 is slidably installed on the ruler frame 1; the measuring device also comprises a positioning rod 2 arranged between the small anvil 11 and the micrometer rod 12 for positioning the side of the automobile piston, a telescopic component 3 arranged on the ruler frame 1 for moving the positioning rod 2 close to or away from the automobile piston, and a moving component 4 arranged on the ruler frame 1 for adjusting the horizontal position of the telescopic component 3.

[0033] When in use, place the automobile piston between the small anvil 11 and the micrometer rod 12, and then adjust the telescopic component 3 according to the size of the automobile piston to move the positioning rod 2 close to the side of the automobile piston. Then, use the moving component 4 to adjust the horizontal position of the positioning rod 2 as needed to ensure that the positioning rod 2 and the side of the automobile piston are parallel and tightly fitted to play a role in positioning support. Move the micrometer rod 12 to make the small anvil 11 and the micrometer rod 12 clamp the automobile piston, and read the clamped measurement data. After the measurement is completed, use the telescopic component 3 to move the positioning rod 2 away from the automobile piston to release the positioning of the automobile piston, and then proceed to the next step.

[0034] Specifically, a receiving groove 13 for accommodating the telescopic component 3 is provided on the ruler frame 1; wherein the telescopic component 3 includes a sliding frame 31 slidably connected in the receiving groove 13, a toothed plate 32 slidably connected in the sliding frame 31 and passing through the receiving groove 13, a rotating shaft 34 rotatably connected in the sliding frame 31 and passing through the sliding frame 31, and a gear 33 fixedly mounted on the rotating shaft 34 and meshing with the toothed plate 32, and the toothed plate 32 is fixedly connected to the end of the positioning rod 2 away from the automobile piston; the user can rotate the rotating shaft 34 to drive the gear 33 to rotate, and since the gear 33 is meshed with the toothed plate 32, the toothed plate 32 can slide back and forth in the sliding frame 31 as the gear 33 rotates, so that the positioning rod 2 can be moved closer to or away from automobile pistons of different sizes by adjusting the distance that the sliding frame 31 slides back and forth, thereby being able to quickly complete the measurement and positioning of the automobile piston or release the positioning of the automobile piston.

[0035] Among them, in order to prevent the tooth plate 32 from sliding off the sliding frame 31, a limit block 321 is fixedly installed on one end of the tooth plate 32 away from the positioning rod 2; the design of the limit block 321 can limit the movement range of the tooth plate 32 when driving the tooth plate 32 to slide in the sliding frame 31, so as to prevent the tooth plate 32 from detaching and improve the stability of the measurement.

[0036] In addition, in order to facilitate the operation of the rotating shaft 34, a through groove 14 connected to the accommodating groove 13 is opened at the upper position of the ruler frame 1 corresponding to the sliding frame 31; due to the design of the through groove 14, the operator can directly observe the position of the rotating shaft 34 on the sliding frame 31 and make appropriate adjustments to it, thereby simplifying the operating steps.

[0037] Furthermore, a slide groove 15 for accommodating the moving component 4 is opened at a position below the sliding frame 31 corresponding to the accommodating groove 13; wherein the moving component 4 includes a slider 41 slidably installed in the slide groove 15 and connected to the bottom of the sliding frame 31, and a screw rod 42 rotatably connected in the slide groove 15 and passing through the slider 41, the screw rod 42 is screwed to the slider 41, and one end of the screw rod 42 passes through the ruler frame 1 and is rotatably connected to the ruler frame 1; since the screw rod 42 and the slider 41 are screwed together, when the user rotates the screw rod 42, the screw rod 42 can be driven to move horizontally in the slide groove 15, and since the slider 41 is fixedly connected to the bottom of the sliding frame 31, the horizontal movement position of the sliding frame 31 can be indirectly adjusted by adjusting the horizontal movement position of the slider 41, so that the sliding frame 31 can synchronously drive the positioning rod 2 to move horizontally, and then the positioning position of the positioning rod 2 can be adjusted according to the size of the automobile piston to adapt to the measurement of pistons of different sizes, thereby improving the flexibility and convenience of the measuring device.

[0038] Example 2

[0039] Different from Example 1, in order to further improve the convenience of the measuring device, a handle 5 is fixedly installed on the side of the ruler frame 1 away from the small anvil 11 and the micrometer rod 12; when the user measures the size of the automobile piston, the user can move or hold the ruler frame 1 by holding the handle 5 to reduce the inconvenience of the user in adjusting the measuring device.
