Detailed Description

The utility model is realized by the following technical scheme.

A telescopic simulated spring mechanism comprises an inner ring handle 11, an outer ring handle 12, screws 13 (three), spring washers 14 (three), gaskets 15 (three), a push rod base 16, a rear insulating sheet 17, screws 18 (two), a resistor 19, a nut 20, a spring washer 21, gaskets 22, a gland 23, a negative core 24, a front insulating sheet 25, a positive conductive ring 26, a diagonal guide post 27 and a return spring 28.

One end of the inner ring handle 11 sequentially passes through the outer ring handle 12, the ejector rod base 16, the rear insulating sheet 17, the anode conducting ring 26, the front insulating sheet 25 and the inner hole of the gland 23 and then is fixed by the nut 20, the spring washer 21 and the gasket 22. The positive electrode conductive ring 26 is arranged between the rear insulating sheet 17 and the front insulating sheet 25, the rear insulating sheet 17 insulates the positive electrode conductive ring 26 from the ejector rod base 16 at intervals, and the front insulating sheet 25 insulates the positive electrode conductive ring 26 from the inner ring handle 11 and the negative electrode core 24 at intervals. The inner hole of the ejector rod base 16 is provided with a reset spring 28, and two ends of the reset spring 28 are respectively fixed by the inner ring handle 11 and the rear insulating sheet 17. The negative electrode core 24 is disposed between the gland 23 and the front insulating sheet 25. The resistor 19 is welded at one end to the positive conducting ring 26 and at the other end to the gland 23.

The inclined guide post 27 penetrates through the ejector rod base 16 and then is inserted into the guide hole of the negative core 24, and the inclined guide post 27 can axially move along with the outer ring handle 12 and the ejector rod base 16. The hole in the negative core 24 into which the diagonal guide post 27 is inserted is a guide hole inclined in a direction close to the axis of the inner ring handle 11. The axial sliding distance of the outer ring handle 12 is limited by the baffle structure on the inner ring handle 11 and the rear insulating sheet 17.

When the baffle plate of the inner ring handle 11 is opposite to the bullet clamping device and is connected with the end face of the trigger injection tube, the simulated bullet negative electrode core 24 is positioned right below the bullet clamping device and keeps a fixed vertical distance, the outer ring handle 12 is pushed until the rear insulating plate 17 is contacted, the reset spring 28 is gradually compressed, the length of the inclined guide post 27 inserted into the negative electrode core 24 is gradually prolonged, and the negative electrode core 24 moves along the radial direction far away from the inner ring handle 11, so that the arc groove at the end part of the negative electrode core 24 is embedded into the bullet clamping device. It is not necessary to observe the slot opening of the launching tube to distinguish whether the simulated projectile is in place.

When the ring handle 12 is loosened after the measurement reading is finished, the compressed reset spring 28 pushes the outer ring handle 12 and the inclined guide post 27 towards the direction far away from the gland 23 in the process of converting elastic potential energy into kinetic energy, the length of the inclined guide post 27 inserted into the negative core 24 is gradually shortened, the negative core 24 moves towards the radial direction close to the inner ring handle 11, and when the end face of the outer ring handle 12 contacts with the baffle, the end part of the inclined guide post 27 still remains in the inclined guide post 27. Therefore, the tool prying and clamping bullet device is canceled, and the tool is prevented from scratching the transmitting tube and the clamping jaw.
