Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, 2, 5 and 6, in an embodiment of the present invention, a single-rod cylinder casing includes a casing main body 1, a piston rod hole 2 is formed at one end of the casing main body 1, an air hole 4 is formed at one side of the lower surface of the casing main body 1, which is close to the piston rod hole 2, an air intake chamber is formed between one side of the inside of the casing main body 1, which is close to the piston rod hole 2, and a piston 8 is disposed inside the casing main body 1, that is, a piston rod is mounted on the piston 8, and one end of the piston rod passes through the piston rod hole 2, the piston rod is in an extended state at an initial state, air is introduced from the position of the air hole 4, and pushes the piston 8 to move, so that the piston 8 can gradually retract into the inside of the casing main body 1;

as shown in fig. 2 and fig. 3, in order to make the gas quickly push the piston 8 during initial air intake, a component for reducing the size of the air intake chamber is arranged inside the air intake chamber, that is, the accommodation capacity of the whole air intake chamber is reduced, and only a small amount of gas needs to enter to make the gas push the piston 8, so as to accelerate the initial operation of the piston;

the first embodiment is as follows:

as shown in connection with fig. 3 and 5, an assembly for reducing an intake chamber comprises: the inner wall of the air inlet cavity is provided with a filling ring 6, a small air inlet cavity 5 is formed inside the filling ring 6, the cavity between the small air inlet cavity 5 and the piston rod is the initial air inflow which is smaller so as to accelerate the initial running speed of the piston, and preferably, a sealing ring 7 is arranged between the filling ring 6 and the small air inlet cavity 5 so as to prevent air from entering between the filling ring 6 and the shell main body 1;

example two:

as shown in connection with fig. 4 and 6, an assembly for reducing an intake chamber comprises: the inner wall of the air inlet chamber is set to be in a circular truncated cone shape, the circular truncated cone-shaped air inlet cavity 13 is formed inside the circular truncated cone-shaped inner wall, the maximum diameter of the circular truncated cone-shaped air inlet cavity 13 does not exceed the inner diameter of the shell main body 1, namely the accommodating capacity of the whole circular truncated cone-shaped air inlet cavity 13 is reduced, and therefore the initial running speed of the piston is accelerated.

Referring to fig. 2 and 3, a side-by-side connecting plate 10 is disposed on a side of the piston 8 away from the piston rod hole 2, between two adjacent connecting plates 10, a small spring 9 is disposed between the connecting plate 10 of the end portion and the piston 8 and between the connecting plate 10 of the other end portion and the inner end of the piston rod hole 2, the original longer and larger long spring is converted into the small spring 9, the connecting plates 10 are connected, so that the small springs 9 are compressed one by one, the long spring skew condition caused by the one-time compression of the long spring is avoided, the service life of the spring 9 can be prolonged, a first air hole 101 is disposed on the connecting plate 10, a second air hole 12 is disposed below one end of the housing body 1 away from the piston rod hole 2, and the second air hole 12 is used for discharging and entering of air in a right chamber of the piston 8 during the moving process.

The utility model discloses a theory of operation and use flow: when using this device, install the piston rod on piston 8, piston rod hole 2 is passed to the one end of piston rod, when the gas pocket 4 admits air, because the less that the air inlet chamber set up, so gas can be full of it fast to the quick work of 8 initial conditions of piston, at the in-process of 8 right movements of piston, little spring 9 of compression that can be gradual, on the contrary when gas pocket 4 exhausts, little spring 9 is in the resilience state, makes the piston rod extension.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof.
