Problems solved by technology

[0005] This method in the prior art is simple and easy, but it takes a long time to detect, which will seriously reduce production efficiency; and, once the test fails, due to the very high air tightness requirements of the gun sight, the gun sight immersed in water will In the state of poor airtightness, water will seep into the gun sight, which will cause the repair to be completely disassembled and repaired, and dry and clean, etc., resulting in longer repair time, and it is difficult to repair successfully, so it is a waste of time and production. extremely inefficient

Embodiment Construction

[0028] The invention provides a device for testing the airtightness of gun sights, the principle of which is as follows: figure 2 As shown, the device includes: a sealing component 200 , a gas source device 300 , a pressure sensing device 400 , an analysis device 500 and a display device 600 .

[0029] The sealing part 200 is used to seal the seams of the rifle scope 100, and the seams are the parts where airtight defects may appear on the rifle scope 100, such as the eyepiece section 110, the objective lens section 120 and the middle knob section 130, and the seams The position does not include the air hole 150 of the gun sight 100 . The sealing in this embodiment includes: the opening and closing cover parts constituting the main body, and the sealing rings arranged between and inside the opening and closing cover parts. The opening and closing cover is provided with a gap that matches the section of the gun sight 100. When the gun sight 100 is placed in the opening and cl...

Abstract

The invention discloses equipment for testing the gas tightness of weapon sight and a method thereof. The equipment comprises: an air supply device which is connected with an air hole on the weapon sight for forming enough differential pressure in the weapon sight relative to the atmosphere pressure to test the gas tightness of the weapon sight; an sealing part which has a sealing space for sealing a sewing part of the weapon sight; and a pressure inducing device which is arranged on the sealing part for inducing the change of the air pressure in the sealing part. The method and the equipment adopt air pressure test, thereby being capable of saving the test time and improving the production efficiency.

Description

technical field [0001] The invention relates to an airtightness test of an optical instrument, in particular to a device and method for testing the airtightness of a gun sight. Background technique [0002] A gun sight is a device on a gun used to aim at a target, usually for precision shooting, and consists of a set of lenses. Because the gun sight is usually equipped with the gun, it is in a harsh environment exposed to the sun and rain, and it may be bumpy during use. The inside of the rifle scope is the optical device used for aiming. Once dust or mold forms inside it, it will cause the optical performance of the optical device to decline, and even directly lead to the scrapping of the rifle scope. Therefore, the airtightness of the gun sight after production will directly affect its anti-rust performance, anti-corrosion performance, anti-mold performance, anti-fog performance and dust-proof performance, thus determining the quality and service life of the gun sight. ...
