The present invention relates to a toy gun magazine module, capable of being filled with gas directly and used repeatedly.
High pressure gas providing types for conventional pneumatic toy guns may be divided into two types: external gas cylinder type and built-in gas cylinder type.
The external gas cylinder type mainly is configuring a lock device on the barrel of a conventional pneumatic toy gun, and coupling the toy gun with a high pressure gas cylinder having a lock portion and switching valve corresponding to the lock portion configured on the end thereof by engaging the lock portion with lock device, thereby allowing the high pressure gas in the gas cylinder to be input continuously into the toy gun by operating the switching valve in coordination with the lock device so as to provide bullet firing power for the gun. But, such type of high pressure gas cylinder adds to much weight to the toy gun upon use thereon, and a new one needs to be purchased after the high pressure gas in the gas cylinder is used up, so the cost is higher.
As to the built-in gas cylinder type, it is configuring a clamping piercing structure inside the barrel of a conventional toy gun, placing a high pressure gas cylinder in which high pressure gas is stored on the clamping piercing structure, and operating the clamping piercing structure to pierce the high pressure gas cylinder, allowing the high pressure gas to flow out thereof to provide power. But operating clamping piercing structure is rather troublesome and time consumptive, and a new high pressure gas cylinder needs to be purchased again after the high pressure gas in the high pressure cylinder is used up, so the cost is higher too.
To overcome the disadvantage of the high cost resulting from the impossible repeated use in the prior art, and to achieve direct gas-filling and repeated use, the present invention is proposed.
The main object of the present invention is to provide a toy gun magazine module, capable of gas refill when gas pressure is insufficient so as to achieve repeated use.
Another object of the present invention is to provide a toy gun magazine module, being convenient and portable for use.
To achieve the objects mentioned above, the present invention proposes a toy gun magazine module, including: a magazine body, allowing a plurality of shooting elements to be mounted therein; at least one gas storage space, defined in the magazine body, and allowing high pressure gas to be stored therein to provide power for firing the plurality of shooting elements; at least one gas inlet, configured on at least one side of the magazine body, and in communication with the gas storage space; and at least one check valve set, configured on the gas inlet, allowing the unidirectional input of the high pressure gas in the gas storage space, and closable automatically to prevent the high pressure gas from flowing reversely to leak out. Furthermore, a firing gun chamber in communication with the gas storage space is configured on one end of said magazine body, and a load chamber in communication with the firing gun chamber on one side thereof. Furthermore, a firing member adapted to close the gas storage space selectively is configured between the firing gun chamber and load chamber.
Because the magazine body has the gas inlet in communication with the gas storage space, and the check valve set is configured on the gas inlet, the gas storage space normally is in a closed state through the check valve set, and the gas intake may be selectively installed on the check valve set and further connected to an external aeration device or inflation device, allowing high pressure gas to flow into the check valve set through the aeration device or inflation device. Meanwhile, the high pressure gas pushes the check valve set open to cause it in an open state so that the high pressure gas enters the gas storage space directly and is stored therein for subsequent firing, and the check valve set is recovered back to the closed state when the input of the high pressure gas is stopped.
Since the present invention need not be in connection with a high pressure gas cylinder, the entire weight can be reduced and convenient for use. In addition, the present invention is portable without any space limit and capable of repeated gas-filling such that the cost can be decreased, with the pressure variation of the high pressure gas resulting from environmental temperature change to influence the stability of bullet shooting speed being capable of being avoided.
Referring to
one end of the magazine body 10 has a firing gun chamber 11 in communication with the gas storage space 14 and an load chamber 12 at one side of the firing gun chamber 11 and in communication therewith, and the firing member 20 for sealing the gas storage space 14 selectively is configured between the firing gun chamber 11 and load chamber 12, where the firing member 20 includes a mandrel closing loop 23 configured in the firing gum chamber 11 and far away from the load chamber 12, a mandrel tightening piece 22 configured on the mandrel closing loop 23 and adjacent to the load chamber 12, a mandrel 21 configured in the firing gun chamber 11 and extended in an gastight way in the load chamber 12, mandrel closing loop 23 and mandrel tightening piece 22, and a mandrel spring 24, where a main gas hole 211 is opened on one end of the mandrel 21 adjacent to the load chamber 12, and at least one side gas hole 212 in communication with the main gas hole 211 is configured on one end of the mandrel 21 close to the firing gun chamber 11, so that the mandrel spring 24 will press the mandrel 21 to cause the mandrel tightening piece 22 to block the side gas holes 212 from being in communication with the firing gun chamber 11 in a normal state.
A bullet guide slot 13 in communication with the load chamber 12 is formed in the magazine body 10, and the bullet lift member 30 is configured on the bullet guide slot 13, where the bullet guide slot 13 includes a lift element 31 configured movably on the bullet guide slot 13, a positioning seat 32 configured on the bottom of the bullet guide slot 13, and a lift spring 33 connected between the lift element 31 and positioning seat 32 to provide the lift element 31 with spring force.
The check valve set 40 is configured on the gas inlet 15, and allows high pressure gas to be input unidirectionally in the gas storage space 14 and closed automatically to prevent the high pressure gas inside the gas storage space 14 from flowing reversely and leaking, where the check valve set 40 includes a valve body 41 configured on the gas inlet 15, a spring 42 configured movably in the valve body 41, and a check valve element 43 configured movably on one side of the spring 42, where a through hole 413 is configured on one end of the valve body 41 adjacent to the gas storage space 14, and a group interface 414 is formed on one end of the valve body 41 far away from the gas storage space 14. Furthermore, a movable chamber 415 for the accommodation of the spring 42 and check valve element 43 is defined between the through hole 413 and group interface 414, and a valve hole 416 is formed between the movable chamber 415 and group interface 414 to allow them to be in communication with each other, where the valve hole 416 is smaller than the movable chamber 415 and the group interface 414 in diameter, with the check valve element 43 being operated in coordination with the spring 42 to close the valve hole 416 normally. Furthermore, the valve body 41 includes a valve body 411 configured on the gas inlet 15 and having the group interface 414, valve hole 416 and movable chamber 415, and a valve block 412 configured on one end of the valve body 411 adjacent to the gas storage space 14 and having the through hole 413, where the inner side wall of the group interface 414 may be formed with threads, a gastight washer 44 is put around the valve body 411, and the outer surface thereof is formed with threads, thereby being in engagement with the gas inlet 15.
The intake joint 50 may be configured selectively on the group interface 414, and have a connection end portion 51 formed on one end thereof adjacent to the group interface 414, where the outer surface of the connection end portion 51 is formed with threads, and a gastight ring is further configured on the connection end portion 51.
The dustproof cover 60 may be selectively configured on the group interface 414 and may be formed from elastic material such as rubber, where the dustproof cover 60 includes a cover body for coveting the group interface 414, and a group end portion 61 for the insertion thereof in the group interface 414 formed on one side of the cover body.
Upon the use of the present invention, a plurality of firing elements such as biodegradable bb pellets or paintballs may be mounted into the bullet guide slot 13, the intake joint 50 is then engaged with the group interface 414, and the intake joint 50 is connected to an aeration device such as pump or inflation device, allowing the aeration device or inflation device to input high pressure gas to open the check valve set 40 temporarily and the high pressure gas can then enter directly into the gas storage space 14 unidirectionally. When the gas pressure in the gas storage space 14 is large enough to stop the input of high pressure gas, the check valve set 40 is closed automatically, thereby preventing the high pressure gas inside from leaking out.
In addition, the dustproof cover 60 may be covered on the group interface 414 to prevent foreign matter from entering the gas storage space 14.
Upon use, a user may install the present invention directly in the gun-grip to play shooting; the present invention has a high degree of simulation because the present invention is very close to a real (real bullet) magazine whether in appearance or use. Upon shooting, a toy gun trigger will strike the mandrel 21 to cause it move, allowing the high pressure gas inside the firing gun chamber 11 (gas storage space 14) to enter the main gas hole 211 through the side gas holes 212 to fire the shooting elements in front of the mandrel 21.
