Abstract

The utility model relates to a cartridge case projecting mechanism for a colour bullet firing device, which belongs to the field of sport apparatuses. An assembly piece of the mechanism is arranged at the bullet firing port of a short type pistol. The mechanism comprises a press case sleeve, a centre shaft column and a case projecting sleeve, wherein the press case sleeve is positioned at the upper part of the mechanism and is connected with a torsion spring; the case projecting sleeve is positioned at the lower part of the mechanism, can rotate around the centre shaft column and is connected with a torsion spring. The mechanism can make a colour bullet firing device generate verisimilitude and liveness, has the efficacy that a cartridge case can be projected as shooting in the process of firing a colour bullet and can increase the interest of exercisers.

Description

The impelling shell case mechanism of paintball firing device

Technical field

The utility model belongs to the sports apparatus field, specially refers to shooting sports and prizes and play the impelling shell case mechanism of firing device.

Background technology

Various colourful amusements, body-building, become indispensable important component part in the vast lives of the people, the shooting activity also is one of them, in order to bring more true to nature for the people that participate in shooting sports, more lively enjoyment, our company successively developed the product of multiple shooting usefulness at spear or short arm formula, as the patent No. is that 01218573.6 " can regulate the paintball firing device of percussion speed " (the authorizing) and the patent No. are 03276495.2 " pistol type paintball firing device " (authorizing), and the firing device of existing imitative gun type is in the percussion process, be not possess with sending out with the function of throwing shell case, this has just lacked very strong emulation, also can make the investor who participates in this type games little to the demand property of this class firing device.In order to change this state, our company has carried out the improvement of structure to the paintball firing device of such short type, make full use of the process that this firing device has back thorax, the mechanism of impelling shell case while shooting that develops that this people of making feels to be really true to life adopts the paintball firing device of mechanism like this also therefore to increase the attraction.

Summary of the invention

The utility model technical issues that need to address, be in the existing paintball firing device, do not possess, lack emulation and lively sense with the function of emission with the throwing shell case, in order to overcome these weak points, the purpose of this utility model is to provide a kind of impelling shell case mechanism of paintball firing device.The purpose of this utility model realizes by the following technical solutions, a kind of impelling shell case mechanism of paintball firing device, this mechanism's assembly is placed in short pattern pistol and hits bullet mouth place, it is characterized in that, this mechanism comprises a pressure shell cover that is positioned at top and is connected with a torsion spring, a middle jack-post, and one be arranged in the lower part and can and be connected with the ejection chute of a torsion spring around jack-post rotation.

In order to realize the throwing shell case function of this mechanism, at the following ammunition feed casket exit position of overall paintball firing device front end, be provided with the outlet of an impelling shell case, when firing device is pulled the trigger, gases at high pressure utilize air chamber to carry out the transition to and push away the bullet cover, the promotion paintball moves forward, when paintball and its shell case move to when throwing the shell case exit position, because pressure shell is enclosed within the torsion spring effect, the shell case fastening is being thrown on the shell case exit position, push away bullet and be enclosed within the paintball that gas promotes to continue down to promote core and enter gun barrel, to a certain degree enter the ramrod central hole and at once paintball is pulled the trigger away when being displaced to.Simultaneously, pushing away the bullet cover resets rapidly under the spring action that they link to each other respectively with ramrod, another strand gas promotes back the thorax cover, the upper shell that promotes firing device simultaneously moves together backward, and when being displaced to terminal set loxosis, this loxosis is clashed into the ejection chute of this mechanism, it overcomes the torsion spring effect, rotate to an angle around middle jack-post, rapidly shell case is released, finish the ejection process.

The torsion spring that described pressure shell cover and ejection chute are connected respectively all is arranged on the position that the damping pressure shell overlaps and ejection chute rotatablely moves respectively.

The beneficial effects of the utility model are, this mechanism can make the paintball firing device produce verisimilitude and lively sense, have in paintball percussion process with shooting with the effect of throwing shell case, increase sporter's temperament and interest effectively.

The specific embodiment

With reference to Fig. 1, Fig. 1 a, expression paintball firing device paintball loads, Deng battery, also promptly utilize this throwing shell case mechanism projectile body shelly attitude, the figure middle and upper part is the pressure shell cover 1 of this mechanism, the mechanism bottom is an ejection chute 3, the middle part is middle jack-post 2, extension spring 7 and extension spring 11 are separately positioned on the position of damping pressure shell cover 1 and the motion of damping ejection chute among the figure, ammunition feed casket exit position front end is provided with impelling shell case outlet 12 under firing device, when firing device is pulled the trigger, gases at high pressure utilize air chamber to carry out the transition to push away bullet cover 4, promote shell case 5 and paintball 6 and move forward, when shell case 5 moves to when throwing shell case and going out 12 position, because pressure shell cover 1 exports on 12 positions at the throwing shell case in a following shell case 5 fastenings of the effect of torsion spring 7, enter gun barrel and push away bullet cover 4 continuation promotion paintballs 6, when being displaced to certain distance, pressed gas enters the centre bore of ramrod 8, thereby paintball 6 percussions are gone out, simultaneously shell case 5 is dished out.

The state of representing the intact shell case of impelling with reference to Fig. 2, Fig. 2 a, when paintball is pulled the trigger, pushing away bullet cover 4 and ramrod 8 resets rapidly under spring action, another strand gas promotes back thorax cover 9, returning thorax cover 9 spurs upper shell 10 simultaneously and moves backward together, upper shell 10 is established a loxosis 13 at the homonymy shell end in impelling spring exit 12 and (is seen Fig. 1 a), when being displaced to herein, loxosis 13 bump ejection chutes 3, the effect that makes this cover overcome torsion spring 11 rotates to an angle around middle jack-post 2 and (sees Fig. 2 a), rapidly shell case 5 is propelled, finished the ejection process.And upper shell 10 moves forward under spring action at once and resets, and when it resetted, the loxosis 13 of this upper shell was separated with ejection chute 3, and this is enclosed within the effect of torsion spring 11 and recovers arm-to-arm immediately.

Claims
