Description

The wedding celebration Kaleidoscope display scope

Technical field

The utility model relates to and a kind ofly ceremonially can eject colour bar or ticker tape bits and play up the wedding celebration Kaleidoscope display scope of lively atmosphere in celebration.

Background technology

In a lot of celebration ceremonies (as wedding, party, cut the ribbon at an opening ceremony etc.), people tend to use Kaleidoscope display scope (also claiming firework spraying tube) to eject many colour bars or ticker tape bits in order to play up lively atmosphere better, to make an ardent celebrating scene.This class Kaleidoscope display scope all is power with compressed air.But, because the structural design of this class Kaleidoscope display scope is limit, the time make one to separate with exhaust outlet and could under compressed-air actuated promotion, the rubber stopper in the exhaust outlet at first be ejected in dispensing with duroplasts or metal compressing tablet, so, in ejection colour bar or ticker tape bits, this rubber stopper also together flies out tens of meters, as same bullet.When the product that has discharges at Compressed Gas hard plastic sheet or sheet metal also together the ejection, be easy to the people or on every side object (as glass, electric light etc.) damage, danger is bigger, more can't use indoor.Also have another kind of Kaleidoscope display scope will extract a safe locking plate earlier before release, exceed simplified release-push and expose fully and make, not noting slightly will actuation button and cause and misplace, easier human body or the object of injuring, and security is extremely low.

The content of utility model

The technical problems to be solved in the utility model is to overcome the deficiency described in the background technology, and provides a kind of security high, flies out and still can guarantee to eject the wedding celebration Kaleidoscope display scope of colour bar and ticker tape bits without any parts.

The corresponding techniques solution is:

Be connected with valve pocket between holding bin and air tank, valve body is axially fixed in the middle of the valve pocket, and the piston in the valve body cooperates with exhaust outlet, is provided with sealing ring between spool the inner and the air inlet, and spool also cooperates with spring.

Its further Technological improvement plan is:

The outer end of spool sinks in the pit.On piston, also be provided with scrobicular ring.And exhaust outlet is that the sleeve pipe of one is connected between valve pocket and the holding bin, and exhaust place in the exhaust outlet is provided with divider.

Because the realization of above technical scheme, not having any object in colour bar and the ejection of ticker tape bits also together penetrates, so do not have the possibility that injures human body or object, security is higher, fundamentally solved the problem that thing was hurted sb.'s feelings, hindered to original Kaleidoscope display scope easily.Simultaneously, the spool termination is sunken in the pit, is concealed design, unless just by movable valve plug Kaleidoscope display scope is discharged specially, otherwise the collision of external object will never cause and misplaces.This Kaleidoscope display scope internal structure is very simple, and design is more reasonable, and it mainly is can not injure people, thing, and security performance is higher, more can use in indoor environment.

Description of drawings

Fig. 1: structural representation of the present utility model.

The A of Fig. 2: Fig. 1 is to view.

The specific embodiment

As shown in Figure 1 and Figure 2, this Kaleidoscope display scope is to be made of holding bin 7, air tank 1, valve pocket 3 and sleeve pipe 6, wherein, is connected with valve pocket 3 and sleeve pipe 6 between air tank 1 and holding bin 7.Valve pocket 3 inherent its axial directions are fixed with valve body 5 by support chip 4, be provided with piston 11 and a spring 2 of having annular scrobicular ring 10 on the plane in the valve body 5, this spring 2 offsets with the inner of spool 13, have a sealing ring 12 between spool 13 and air inlet 15 the inners, and the outer end of spool 13 is exposed in the pit 14 outside the air inlet 15.The axial orthogonal setting of the axial and spool 13 of piston 11.Be provided with a cross divider 8 in the exhaust outlet 9 in the middle of the sleeve pipe 6, this divider 8 designs (referring to Fig. 2) in order to block the range limit and the discharge Compressed Gas of piston 11 in valve body 5.

In this structure, except spring 2 is a metalwork, sealing ring 12 and piston 11 are outside the rubber parts, and other parts all can be by injection molding, and wherein the also available millboard of holding bin 7 is made.

This Kaleidoscope display scope adopts the similar charging connector of automobile or motorcycle inflation of giving to aim at pit 14 and inwardly promote spool 13, make sealing ring 12 break away from sealing state, Compressed Gas will enter in the valve body 5 along the slit between spool 13 and the air inlet 15, and promotion piston 11 moves upward and pushes against exhaust outlet 9.When compressed air continues to enter, will and oppress scrobicular ring 10 and enter in the air tank 1, finish gas replenishment process by the space in the valve pocket 3 along the slit between piston 11 and the valve body 5.When charging connector was removed, spring 2 compressed sealing ring 12 by spool 13 the inners, so Compressed Gas can not let out.

In use, user's movable valve plug 13 that press...withes one's finger moves inward it, sealing ring 12 breaks away from sealing state simultaneously, Compressed Gas in the valve body 5 will release along the slit between spool 13 and the air inlet 15, make piston 11 back sides lose pressure, in air tank 1 under the effect of Compressed Gas, the scrobicular ring 10 of piston 11 outwards expands, and realization is to the sealing of valve body 5, thereby the exhaust outlet 9 that breaks away from sleeve pipe 6 with regard to piston 11 is moved downward, compressed air in the air tank 1 will go out by exhaust outlet 9 moments eruption, and the ticker tape bits and the colour bar of prepackage in the holding bin 7 are gone out fully.This shows that this Kaleidoscope display scope goes out without any parts more thereupon except ticker tape bits and colour bar ejection, so, be the relieved product of safety no matter be all can use outdoor or indoor.And the design of the countersunk head of spool 13 can be avoided unexpected maloperation fully, and performance is reliable especially.
