Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further with specific embodiment, and the purpose of the utility model is realized in this way, as shown in Fig. 1-Fig. 2:

A floor gun firing device, comprising a hollow casing 1, a driving device 9 and a front end cover 6, the driving device 9 is arranged at the rear end of the hollow casing 1, and the front end cover 6 is arranged on the casing 1, the housing 1 is provided with a piston cylinder 2 and a percussion seat 5, the piston cylinder 2 is provided with a large end 23 and a small end 21, and the small end 21 of the piston cylinder is formed from the front end of the housing 1. It extends to the inside of the housing 1 and is connected to the driving device 9, and the large end 23 is connected to the knocking seat 5; the front end cover 6 is provided with a through hole, and the front end of the knocking seat 5 protrudes from the front end through the through hole. Cover 6 outside.

As a first option, the above-mentioned large end 23 is provided with a seal B4, and the small end 21 is provided with a seal A1. The piston cylinder 2 forms a front sealing structure with the inner wall of the housing 1 through the seal B4. The piston cylinder 2 The sealing member A1 forms a rear sealing structure with the inner wall of the housing 1 , and the small end portion 21 of the piston barrel is connected to the driving device 9 through the sealing member A1 .

As a first option, a groove 31 is opened on the housing 1 or the piston cylinder 2 , and the sealing member A1 is located in the groove 31 .

As a first option, the above-mentioned small end portion 21 is provided with an intake support ring 22 .

As a first option, a buffer washer 7 is provided between the above-mentioned front end cover 6 and the striking seat 5 .

As a first option, the above-mentioned front end cover 6 is connected to the front end surface of the casing 1 by screwing.

As a first option, the aforementioned drive means 9 are air cylinders.

As a first option, a positioning device is provided at the front end of the above-mentioned striking seat 5 .

As a first option, the above-mentioned positioning means is a knocking cap 8 .

As shown in Figure 3, knocking the knocking cap 8 drives the piston cylinder 2 to move backward through the structure of the knocking cap 8 and the knocking seat 5 until the knocking cap 8 is positioned on the front end of the front end cover 6, and the high-pressure gas passes through The intake support ring 22 on the small end 21 of the piston barrel enters the cylinder (driver 9) to drive the piston to do work. When the piston does work, part of the gas enters the inside of the piston barrel 2 and the knocking seat 5 through the passage inside the piston, and finally from The front end cap 6 is discharged.

As shown in Figure 4, as the external force of knocking the knocking cap 8 disappears, the high-pressure gas in the cylinder (driving device 9) drives the piston barrel 2 to move forward and is positioned in the front end cover 6 after being buffered by the buffer gasket 7. End face: After the piston cylinder 2 is positioned, it is sealed with the housing 3 through the seals (seal B4 and seal A1) on the large end 23 and the small end 21. At this time, the high-pressure gas is isolated, that is, the high-pressure gas is prevented from entering the cylinder (drive device 9), the residual gas in the cylinder is decompressed through the exhaust passage, and the pressure of the gas is weakened as the driving piston works, and a part of high-pressure gas enters the inside of the piston barrel 2 through the air inlet 24 of the piston barrel 2 to drive the piston forward Reset and stop after being in contact with the percussion seat 5.

In Figure 3 and Figure 4, the small arrows are the intake and driving gases, and the large arrows are the exhaust paths.

The foregoing embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore: all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered by this utility model. within the scope of protection of utility models.
