Abstract

The utility model discloses a guiding rod of a rocket firework, comprising a guiding rod body which is provided with at least one closed cavity full of explosive; a fire-lead of the explosive is connected with an ignition-lead of the rocket firework. After the technical proposal is adopted, the ignition-lead of the rocket firework ignites propellant while igniting a leading wire of the explosive in the guiding rod, the rocket firework rises while the leading wire is burning; after the rising is completed, the leading wire ignites the explosive on the guiding rod body, the guiding rod body is exploded into scraps so as to eliminate the safety hidden-danger of hurting people caused by falling objects completely, and the production procedures are relatively simple, the production cost is lower without any impact on the consumption habit.

Description

A kind of guide post of rocket firework

Technical field

The utility model relates to a kind of rocket class fireworks.Be a kind of guide post of rocket firework specifically.

Background technology

As a kind of traditional product, the basic structure of existing rocket firework product is referring to Fig. 1, comprise effect tube cap 1, ignition fuse 5, launching tube 4, overshoot lead wire 2, effect tube 3, taper tail pipe 6 and guide post 7, ignition fuse is lighted propellant powder, the rocket lift-off reaches design height and lights the effect medicine by overshoot lead wire, represents moulding.Effect for go up to the air guiding and stable transmit direction all has a long guide post at its afterbody, and its length can reach 15 meter, and material generally is wood, bamboo or paper web.This guide post goes up to the air with rocket, and after rocket firework was seted off, guide post might cause damage to ground staff's article from the high-altitude free falling, has bigger potential safety hazard.The design of a lot of cancellation guide posts is also arranged, as adopting empennage or adopting above-ground launcher etc. in the prior art.But, complex manufacturing not ideal enough owing to directional effect, cost be too high, do not meet many-sided reasons such as consumption habit, all do not obtain the approval in market.Most of rocket firework products still adopt traditional guide post design on the market now.

Summary of the invention

In order to address the above problem, the purpose of this utility model provides a kind of guide post of rocket firework, eliminated above-mentioned potential safety hazard under the prerequisite that guarantees the guiding directional effect, and production process is simple relatively, production cost is lower, also can not impact to consumption habit.

To achieve these goals, the technical solution adopted in the utility model is a kind of guide post of rocket firework, comprise the guide post body, be provided with at least one closed cavity on the guide post body, be filled with bursting charge in the cavity, the fire lead-in wire of leading of bursting charge is connected with the rocket firework ignition fuse.

Adopt technique scheme, when the rocket firework ignition fuse is lighted propellant powder, light the lead-in wire of guide post bursting charge, rocket firework lift-off in the lead-in wire burning, after lift-off is finished, lead-in wire ignites the bursting charge that installs on the guide post body, and the guide post body is scraped, and has thoroughly eliminated and has weighed down the potential safety hazard that thing is hurted sb.'s feelings.And production process is simple relatively, and production cost is lower, also can not have any impact to consumption habit.

For the ease of the control of time and simplifying of structure, as preferred embodiment of the present utility model, the fire lead-in wire of leading of described bursting charge ignites in the position that the rocket firework ignition fuse is lighted propellant powder, and promptly the fire lead-in wire of leading of bursting charge is connected with ignition fuse in the position that the rocket firework ignition fuse is lighted propellant powder.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Traditional product structural representation during Fig. 1;

Fig. 2 is the overall structure schematic diagram that the utility model is established a closed cavity;

Fig. 3 is the overall structure schematic diagram that the utility model is established two closed cavities;

Fig. 4 is the overall structure schematic diagram that the utility model is established three closed cavities;

Fig. 5 is the closed cavity structural representation of filling effect medicine layer and bursting charge layer.

The specific embodiment

Referring to Fig. 2, guide post body 8 in this technical scheme is provided with the closed cavity 9 of building bursting charge in one, the ignition fuse 10 of bursting charge is connected with rocket firework ignition fuse 5, and the fire lead-in wire 10 of leading of described bursting charge ignites in the position 11 that rocket firework ignition fuse 5 is lighted propellant powder.

Referring to Fig. 3, be that with the difference of such scheme guide post body 8 is provided with the closed

cavity

9 and 12 of building bursting charge in two, bursting charge is lighted successively by ignition fuse 10 in the closed

cavity

9,12.

Referring to Fig. 4, be that with the difference of technique scheme guide post body 8 is provided with the closed

cavity

9 and 12,13 of building bursting charge in three, bursting charge is lighted successively by ignition fuse 10 in the closed

cavity

9,12,13.Under the situation of the more closed cavities of needs setting, can increase in the manner described above, repeat no more.

Referring to Fig. 5, the utility model can also have another kind of the improvement, is filling effect medicine layer 15 and bursting charge layer 16 in the described closed cavity 14 of this mode with the such scheme difference.Lead-in wire 10 is lighted effect medicine and bursting charge simultaneously, the various moulding of bursting forth when pulverizing guide post.

The above, only be embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model to any simple modification that above embodiment did, be equal to and replace and modify, all fall in the scope of technical solutions of the utility model.

Claims

1, a kind of guide post of rocket firework comprises the guide post body, it is characterized in that, is provided with at least one closed cavity on the guide post body, filling bursting charge layer in the cavity, and the fire lead-in wire of leading of bursting charge layer is connected with the ignition fuse of rocket firework.

2, the guide post of a kind of rocket firework as claimed in claim 1 is characterized in that, the fire lead-in wire of leading of described bursting charge is connected with ignition fuse in the position that the rocket firework ignition fuse is lighted propellant powder.
