The switch integral part comprises a pneumatic assembly, a push rod assembly arranged on the pneumatic assembly, and two groups of combined contacts with the same specification. The switch has long service life, high temperature resistance, convenient assembly and debugging, small size, light weight, and good circuit connection performance. The application further discloses a use method of the airtight pneumatic switch.

This application relates to an optical system and an endoscope. The optical system includes a front lens, a light path conversion element, a rear mirror assembly, and a sensor arranged sequentially from the object side to the image side. The light path conversion element is used to change the direction of light propagation, causing the light rays passing through the front lens to be deflected and incident on the rear mirror assembly. The optical system satisfies: 0.9 < |f F / f|<1.1, 1.2<f R / f < 1.7, 0.63 < |f F / f R |<0.88, where f F f is the focal length of the front lens. R f is the focal length of the rear mirror group, and f is the focal length of the optical system. This application, through the arrangement of the front lens, the optical path conversion element, and the rear mirror group, and by defining the relationship between the focal length of the front lens, the focal length of the rear mirror group, and the focal length of the optical system, enables the optical system to have a better field of view, better image quality, and better miniaturization design.

This invention discloses a terminal strip cutting and separating device, comprising a support, a conveying platform for conveying terminal strips fixed on the support, a cutting assembly located near the discharge end of the conveying platform, and a cutting drive mechanism on the support for driving the cutting assembly to cut the connection between two adjacent terminals in the terminal strip. A conveying push block is located above the conveying platform, and a push block drive mechanism on the support for driving the conveying push block to move back and forth and convey the terminal strip forward. The forward and backward travel of the conveying push block is equal to the distance between the center lines of two adjacent terminals. Compared with the prior art, this invention, when used with a multi-station rotary pressing head, can pre-cut the terminal strip into individual terminals, saving pressing space. Furthermore, it has a simple structure, low cost, and is easy to assemble and debug in practical applications.

The application discloses an assembling device, which comprises a base, a bearing mechanism, a positioning mechanism and a pushing mechanism. The bearing mechanism is arranged on the base and is used for fixing and mounting a shell, and the opening of the shell is arranged in the transverse direction. The positioning mechanism is arranged on the base and comprises a positioning block movably arranged in the transverse direction. The lower end surface of the positioning block is provided with a first positioning surface and a second positioning surface arranged at intervals. The first positioning surface is used for abutting against the upper surface of the shell. The pushing mechanism is arranged below the positioning block and comprises a pushing part movably arranged in the vertical direction. The pushing part is used for pushing upward the fitting part locally bonded to the shell, so that the upper surface of the fitting part abuts against the second positioning surface. Thus, the posture of the upper surfaces of the shell and the fitting part is limited, the state is maintained until the adhesive solidifies, and the assembled product with a specific posture can be obtained. Compared with the existing correction mode which needs laser scanning and cooperation of a multi-axis mechanism, the overall structure is simpler, and the investment cost is reduced.

The application discloses an intelligent robot for fine blasting of underground works and belongs to the technical field of underground work construction equipment, which comprises a moving unit, an anti-skid walking unit and a brake unit are installed on the moving unit, a control module is integrated on the moving unit, a signal antenna is installed on the control module, a section scanning module is installed at the front end of the moving unit and is electrically connected with the control module, a scheme generation module is integrated in a built-in underground work standard blasting parameter library and is electrically connected with the control module, a blast hole fine positioning module is installed at the rear end of the moving unit, and a blasting effect evaluation module is installed on the blast hole fine positioning module. The underground work fine blasting intelligent robot realizes integrated closed-loop operation of the whole blasting process, can replace manual work to enter a high-risk operation environment, reduces overbreak and underbreak, and greatly improves the safety, accuracy and efficiency of blasting operation.
