[0002] The two-dimensional measuring instrument, also known as the image measuring instrument and video measuring machine, is used to measure the dimensions of products and molds. The measuring elements include position, concentricity, straightness, contour, roundness and dimensions related to the reference.

[0003] The existing patent announcement number CN213600014U is a hardware tool production size detection device, which discloses that by setting a protective device, the accumulation of dust on the lens can be reduced; by setting an arc-shaped fixing plate, the protective device can be easily fixed on the lens, thereby ultimately reducing the impact of dust accumulation on the use of the detection device;

[0004] However, in actual use, because the protective device also needs to be installed with lenses to ensure light transmission so as not to affect the normal use of the lens, the lens of the protective device will also affect the clarity of the lens after being contaminated, and the problem of lens obstruction caused by dust accumulation cannot be eliminated. In view of this, we propose a hardware tool production size detection device. Utility Model Content

[0024] Example:

[0025] This embodiment provides a hardware tool production size detection device, referring to Figure 1, including a measuring device 1 and a lens 2, the measuring device 1 and the lens 2 are existing products, the measuring device 1 and the lens 2 are combined and connected, and the product can be observed and tested. Among them, the end of the lens 2 away from the measuring device 1 is detachably installed with a dust cover 3, and the dust cover 3 can block the dust floating toward the lens 2. The dust cover 3 includes an annular main body 31, the main body 31 is sleeved at the lower part of the lens 2, and provides an installation space. A lens 32 is installed in the middle of the main body 31, and the lens 32 is covered at the lower part of the lens 2 to facilitate light transmission and cooperate with The dustproof shell 3 completely wraps the lens 2 without any gap, preventing dust from entering between the top surface of the lens 32 and the lens 2, and an annular groove 33 is provided on the main body 31 below the lens 32. The main body 31 is connected to an air pipe 34 at the annular groove 33. When cleaning is needed, it is only necessary to supply air to the air pipe 34 to facilitate directing the airflow to the annular groove 33 and then blowing it to the bottom surface of the lens 32 to clean the dust on the lower surface of the lens 32 without wiping. This can prevent the lens 32 from being scratched and ensure the service life of the lens 32.

[0026] Reference Figure 2 The air pipe 34 adopts a flexible pipe, which can avoid blocking the removal and placement of hardware parts while taking in air. The air pipe 34 is connected to the external air supply pump. When the air pump is powered, electric air supply can be performed, and regular automatic cleaning can be performed. The control panel can be used to preset the air outlet time interval, which is more convenient to use.

[0027] Reference Figure 3 A convex ring is provided on the main body 31 on the side of the annular groove 33 away from the lens 32. The airflow supplied to the annular groove 33 extends and tilts toward the lens 32, and will flow toward the lens 32 under the guidance of the convex ring. The annular air outlet channel can blow the lens 32 from all sides to achieve more uniform cleaning.

[0028] Reference Figure 3 A ring 35 is installed at one end of the main body 31 close to the lens 2. The ring 35 is made of rubber and is elastic. The inner diameter of the ring 35 is slightly smaller than the outer diameter of the lens 2. After installation, the ring 35 can be stably installed on the lower part of the outer side of the lens 2 through interference fit, ensuring stable installation, and can be quickly disassembled and assembled, easy to use, and quick to maintain.

[0029] Reference Figure 2 A protective cover 4 is installed at the bottom of the main body 31. The protective cover 4 can extend downward to form a relay space to prevent the hardware below from moving close to the lens 32 and to prevent the accessories from easily hitting the lens 32. The protective cover 4 adopts a hollow structure that runs through the top and the bottom. The protective cover 4 is narrow at the top and thick at the bottom, which can ensure the smooth passage of light and the smooth observation.

[0030] Reference Figure 4The protective cover 4 includes a curtain 41, wherein the curtain 41 is made of a flexible material. Before observing the accessories, the lower end can be shrunk, and then when the air is discharged from the air pipe 34, the air flow is sprayed downward, and then the surface of the accessories to be inspected is cleaned, which can facilitate subsequent observation. At the same time, a pull rope 43 is installed at one end of the curtain 41 away from the main body 31. Tightening the pull rope 43 can ensure that the curtain 41 is stably tightened.

[0031] Reference Figure 4 A hollow ring 42 is installed at one end of the curtain 41 away from the main body 31. The hollow ring 42 is made of a bellows or other elastic material, which can be smoothly contracted and can also rebound smoothly after the pull rope 43 is relaxed, thereby ensuring the stable deployment of the lower end of the curtain 41. A through opening is opened on the side wall of the hollow ring 42, and a pull rope 43 is installed in the hollow ring 42. At the same time, the end of the pull rope 43 passes through the side wall of the hollow ring 42 through the through opening, so that the pull rope 43 can be operated from the outside, thereby facilitating the collection and relaxation operations.
