Description

Bullet shooting mechanism for toy gun and automatic toy gun

Technical Field

The embodiment of the utility model relates to the technical field of simulation toy supplies, in particular to a bullet shooting mechanism for a toy gun and an automatic toy gun.

Background

This section introduces the reader with background information that may be relevant to various aspects of the embodiments of the utility model, and is believed to provide the reader with useful background information to aid the reader in a better understanding of the various aspects of the embodiments of the utility model. It is to be understood, therefore, that the description in this section is for the purpose of illustration and not an admission that the prior art is prior art.

Toys are good partners for children, with children's childhood. Toy guns have long been favored by children, especially boys. The toy gun is popular with children because of the effect of bullet shooting and strong interest. The existing toy gun is divided into a toy gun capable of emitting a real object and a toy gun incapable of emitting the real object, wherein the emitted real object comprises bubble resin gel, plastic balls, rubber bands and the like. The prior toy gun generally comprises a gun body, a launching tube, a bullet feeding mechanism, a bullet cavity and a trigger, wherein the launching tube, the bullet feeding mechanism and the trigger are all arranged on the gun body, the bullet feeding mechanism and the trigger are both linked with the launching tube, and the bullet cavity is arranged in the gun body and corresponds to a bullet inlet of the launching tube. The bullet supply device is a bullet supply accessory of the toy gun, is matched with the gun barrel and the shooting assembly, shoots out the bullet (such as water bullet) of the toy gun, and is used for receiving the bullet of the toy gun from the magazine and then sending the bullet into the gun barrel under the action of the power mechanism. The firing assembly operates to expel the bullet from the chamber into the firing tube, and to activate the trigger to rapidly compress and instantaneously release the gas, and to expel the bullet from the chamber in front of the gas through the pusher nozzle at the front end of the cylinder. As shown in fig. 1 and 2, the operation of the existing launching mechanism is as follows: a boss 711 on one side of the reduction gear 71 drives a pull bridge 723 on the push nozzle 73, the push nozzle 73 is pulled back a certain distance, the bullet 79 enters the area 77 to be shot, and the reduction gear 71 continues to move the push nozzle 73 to reset; the piston 75 is compressed and released, compressing the gas in the cylinder 70 forces the bullet 79 to fire. The push nozzle 73 of the existing launching mechanism needs to drive the gear 71 of the piston 75 to drive the pull bridge 723 and the spring 78 to reciprocate in a matched mode, the situation that the push nozzle is not timely reset and is not synchronous with the release of the piston 75 can not be timely formed, air leakage is caused, and the structure of the pull bridge 723 part needs to be changed to reset the push nozzle as early as possible. The high shooting speed can lead to the early release of the pushing nozzle and the incompatibility of the bullet feeding mechanism, so that the bullet feeding mechanism can form a seal without timely bullet feeding, and the empty bullet condition is caused.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 3 to 6, an embodiment of the present utility model provides a bullet firing mechanism for a toy gun, comprising: a firing cylinder body 1 arranged in the gun body and a bullet feeding mechanism 5 communicated with the firing cylinder body 1; the tail of the launching cylinder body 1 is communicated with the bullet-emitting power device 3, the tail of the launching cylinder body 1 is provided with an air inlet through hole 10, and the head of the launching cylinder body 1 is communicated with the bullet-feeding mechanism 5; a transmitting piston 4 is sleeved in the cylinder body 1, and the transmitting piston 4 reciprocates in the cylinder body 1; the bullet feeding mechanism 5 comprises an air inlet pipe 51, a bullet feeding port 50 and a bullet discharging pipe 57 which are communicated with each other, the head of the launching cylinder body 1 is communicated with the air inlet pipe 51, the bullet feeding port 50 is connected with the bullet feeding mechanism 6, and the bullet discharging pipe 57 is communicated with the gun barrel 9; the firing piston 4 is provided with a pushing nozzle mechanism 41 towards the head of the firing cylinder body 1, and the head of the pushing nozzle mechanism 41 extends out from the head of the firing cylinder body 1 to push the bullet 8 entering from the bullet inlet 50 into the bullet outlet pipe direction; the bottom of the emission piston 4 is provided with a ventilation through hole 40, the mouth pushing mechanism 41 is hollow, and the air inlet through hole 10, the emission cylinder body 1, the ventilation through hole 40 and the mouth pushing mechanism 41 form a ventilation channel; the firing piston 4 is further provided with a reset device 46 to reset the firing piston 4 after being pushed out. A detailed description of the deployment of a bullet firing mechanism for a toy gun is provided below in accordance with an embodiment of the present utility model.

The bullet shooting mechanism for the toy gun provided by the embodiment of the utility model has the following working procedures: as shown in fig. 5, the gas released by the bullet-emitting power device enters the tail part of the launching cylinder body 1 from the air inlet through hole 10, the gas entering the launching cylinder body 1 pushes the launching piston 4 to move towards the head part of the launching cylinder body 1, and the launching piston 4 drives the nozzle pushing mechanism 41 to enable the head part of the nozzle pushing mechanism 41 to extend out of the head part of the launching cylinder body 1; as shown in fig. 6, the head of the firing cylinder block 1 is extended to push the bullet 8 entering from the inlet 50 into the direction of the discharge tube 57. Further, as shown in fig. 4 and 7, the air in the firing cylinder block 1 is blown out from the head of the pusher mechanism 41 through the ventilation passage, and the blown air forces the bullet 8 in the bullet discharging tube 57 to complete the firing action of the bullet 8. The bullet-emitting power means ends to release the gas after the completion of the firing, and the reset means 46 resets the firing piston 4 after the ejection to the initial state.

As shown in fig. 4 to 7 and 9, in the embodiment of the present utility model, in order to ensure sufficient air pressure during the forward movement of the firing piston 4 and avoid the gas leaking out of the ventilation through hole 40 in advance, a positioning protrusion 11 is disposed on the inner side of the tail of the firing cylinder block 1, and the extending direction of the positioning protrusion 11 is the same as the extending direction of the nozzle pushing mechanism 41. In order to further secure the sealability of the transmitting piston 4 when it moves forward in the transmitting cylinder block 1, the outer diameter of the positioning boss 11 is equivalent to the inner diameter of the ventilation through hole 40.

As shown in fig. 7, 9 and 10, in order to avoid that a plurality of bullets 8 in the bullet supply mechanism 6 enter the bullet inlet 50 at the same time, a bullet blocking mechanism 58 is disposed in the bullet discharge tube 57, and the inner diameter of the bullet blocking mechanism 58 is slightly smaller than the outer diameter of the bullets 8. A slightly greater pressure is required to re-fire the bullet 8 to force the bullet 8 into the blocking mechanism 58 from time to time. The blocking mechanism 58 provides a certain resistance and prevents too many cartridges 8 from entering the discharge tube 57 in the natural state. In embodiments of the utility model, the bullet may be a water bullet or other flexible spheroid.

As shown in fig. 8, in order to avoid the air leakage during the process of firing the bullet 8, the end of the nozzle pushing mechanism 41 is provided with a sealing rubber ring 43, and correspondingly, a funnel-shaped slope 59 is arranged in the bullet discharging tube 57 at a position close to the bullet inlet 50; the head of the nozzle pushing mechanism 41 protrudes from the head of the firing cylinder body 1 and pushes the bullet 8 entering the bullet inlet 50 into the bullet blocking mechanism 58, and the sealing rubber ring 43 abuts against the slope 59 for sealing. The funnel-shaped slope 59 can facilitate the extension of the head of the firing cylinder block 1 to push the bullet 8 entering from the bullet inlet 50 into the direction of the bullet-blocking mechanism 58 into the bullet-discharging tube 57.

As shown in fig. 7, in order to effectively ensure that the length H of the firing cylinder block 1 is longer than the length H of the nozzle pushing mechanism 41 moving in the air intake pipe 51 at the time of firing, the bullet 8 entering the bullet inlet port 50 is pushed into the bullet blocking mechanism 58 after the head of the firing cylinder block 1 is extended. Further, to ensure firing, the length d of the positioning boss 11 is smaller than the length h of the nozzle pushing mechanism 41 moving in the intake pipe 51 to ensure that the intake through hole 10, the firing cylinder block 1, the ventilation through hole 40, and the nozzle pushing mechanism 41 have formed a ventilation passage before the firing piston 4 moves to the head of the firing cylinder block 1. Meanwhile, the sealing rubber ring 43 covers the bullet inlet 50 after the head of the firing cylinder body 1 extends out, so that the situation of superfluous bullet feeding can be avoided.

As shown in fig. 5 and 9, in order to effectively ensure that the firing piston 4 can reciprocate within the firing cylinder block 1, the firing piston 4 is further provided with a reset device 46. Alternatively, the return means 46 is a return spring, which is arranged between the firing piston 4 and the head of the firing cylinder block 1 within the firing cylinder block 1.

As shown in fig. 9, for easy disassembly, installation and maintenance, the engine block 1 includes a detachable cylinder body 12 and a cylinder base 13, and the cylinder body 12 is detachably and fixedly connected with the cylinder base 13 in a sealing manner. The cylinder body 12 is fixedly connected with the cylinder base 13 through threads.

As shown, the outer edge of the transmitting piston 4 is provided with a first sealing rubber ring 48. It is possible to effectively avoid the occurrence of air leakage of the transmitting piston when the transmitting cylinder block 1 moves. A second sealing rubber ring 47 is arranged in the ventilation through hole 40. After the emission piston 4 is reset, the second sealing rubber ring 47 is tightly sleeved on the positioning protrusion 11, and when the emission piston 4 moves forwards, the positioning protrusion 11 cannot leak air in the ventilation through hole 40 of the emission piston 4.

In order to further embody the advantages of the bullet shooting mechanism for the toy gun provided by the embodiment of the utility model, the embodiment of the utility model also provides an automatic toy gun applying the bullet shooting mechanism for the toy gun, as shown in fig. 11, the automatic toy gun comprises a wave box 2, and the bullet shooting mechanism and the firing mechanism are arranged in the wave box 3; the bullet firing mechanism is the bullet firing mechanism described above.

In the embodiment of the utility model, the bullet-emitting power device is optionally a large power cylinder device 21, the power cylinder device 21 is arranged at the tail part of the shooting pot body 1, and the air flow released by the large power cylinder device drives the shooting piston 4 of the shooting pot body 1 to move. The power cylinder 21 mainly provides pneumatic driving force, including driving force to the firing cylinder block 1 and blows out bullets. Unlike the power cylinder device 21, the power cylinder device 21 generates a thrust force by the power cylinder device 21, and the head of the power cylinder device 1 is extended to push the bullet 8 entering from the bullet inlet 50 into the direction of the bullet-blocking mechanism 58 and into the bullet-discharging tube 57. The bullet is blown out further through the vent channel formed. The engine block 1 is a functional cylinder, and the power cylinder device 21 is a power cylinder. In the embodiment of the utility model, the basic parts of the firing mechanism, the bullet supply mechanism, the electric driving mechanism and the like of the toy gun can be realized by adopting the existing relatively mature structure or device, and are not described in detail herein.

In summary, according to the bullet shooting mechanism for the toy gun and the automatic toy gun provided by the embodiments of the utility model, the shooting cylinder body arranged in the gun body is communicated with the bullet feeding mechanism of the cylinder body, so that the shooting mechanism and the driving mechanism are effectively ensured to be synchronous no matter at high and low shooting speeds. The bullet entering the bullet feeding mechanism is launched out by driving the launching piston in the launching cylinder body through high-pressure gas, and the bullet feeding mechanism can follow and reset at any time, so that the condition of empty bullets is avoided.
