Description

Technical Field

[0001] The utility model relates to the technical field of fuse protection, in particular to a fuse protection device produced using dry fireworks. Background Art

[0002] In the process of fireworks production, fuse is an indispensable raw material. However, with the advancement of production technology, in mechanized large-scale production, bundles of fuse need to be pulled to processing equipment for use. Due to the flammable nature of fuse, protective devices need to be used during the pulling process to ensure the safety of the fuse during the pulling process and avoid fire caused by fuse burning.

[0003] When existing devices detect that the fuse is burning, they usually use a cutter to cut the fuse to prevent it from continuing to burn. However, on the one hand, after the fuse burns, the temperature inside the device is high and the fuse may still burn; on the other hand, after cutting the fuse, the fuse needs to be reinserted, which is time-consuming and troublesome. Utility Model Content

[0004] The purpose of the utility model is to provide a fuse protection device produced by dry fireworks to solve the above-mentioned shortcomings in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A fuse protection device produced using dry fireworks includes a safety tube, on which a trigger assembly and a blocking assembly are respectively provided. The blocking assembly includes a blocking tube fixedly arranged on the safety tube, and two inclined plates fixedly arranged in the blocking tube, on which balloons filled with water are placed.

[0007] Furthermore, the trigger assembly includes an ignition wire fixedly mounted on the safety tube, one end of the ignition wire is formed into an annular ring, and the other end passes through the safety tube and is connected to the transmission member. A limit rod is arranged in the safety tube, and the limit rod passes through the annular ring.

[0008] Furthermore, the transmission part includes a connecting rope fixedly connected to the ignition wire, the end of the connecting rope is fixedly connected to a pressure block, the pressure block is slidably connected to the support frame on the blocking tube, a compression spring is arranged between the pressure block and the support frame, and the pressure block is fixedly connected to a nail on the side facing the balloon.

[0009] Furthermore, a guide frame is provided on the safety tube, and the ignition wire is slidably connected to a slide groove on the guide frame.

[0010] Furthermore, the safety tube is provided with a water collecting cylinder corresponding to the position of the blocking cylinder, the bottom of the water collecting cylinder is detachably connected to a cover body, and the water collecting cylinder is communicated with the interior of the safety tube.

[0011] Furthermore, the cover body is threadedly connected to the water collecting cylinder.

[0012] In the above technical solution, the utility model provides a fuse protection device for dry fireworks production with the following beneficial effects:

[0013] Through the blocking component that is set up, the fuse is passed through the safety tube. When the fuse burns, the balloon will be punctured by the trigger component, so that the water in the balloon can wet the fuse, prevent the fuse from burning and extinguish the fire. It is highly safe, and the fuse can be pulled out of the safety tube and then cut off without passing it through the safety tube again. In addition, the use of balloons is low in cost, which reduces production costs.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] See also Figure 1-4 A fuse protection device for dry fireworks production includes a safety tube 1, on which a trigger component 2 and a blocking component 3 are respectively provided. The blocking component 3 includes a blocking tube 31 fixedly arranged on the safety tube 1, and two inclined plates 32 are fixedly arranged in the blocking tube 31, and balloons 33 filled with water are placed on the two inclined plates 32.

[0025] By setting up the blocking component 3, the fuse is passed through the safety tube 1. When the fuse burns, the balloon 33 will be punctured by the trigger component 2, so that the water in the balloon 33 can wet the fuse, prevent the fuse from burning and extinguish the fire. The safety is high, and the lead can be pulled out of the safety tube 1 and then cut off without passing it through the safety tube 1 again. In addition, the use of the balloon 33 is low in cost, which reduces production costs.

[0026] Furthermore, the trigger assembly 2 includes an ignition wire 21 fixedly arranged on the safety tube 1, one end of the ignition wire 21 is formed into an annular ring, and the other end passes through the safety tube 1 and is connected to the transmission member 22. A limiting rod 23 is provided in the safety tube 1, and the limiting rod 23 passes through the annular ring.

[0027] The fuse passes through the annular ring. When the fuse burns through the annular ring of the ignition wire 21, the burning of the annular ring causes the limiting rod 23 to release the limit on the annular ring, and then the balloon 33 is burst through the transmission member 22.

[0028] Furthermore, the transmission member 22 includes a connecting rope 221 fixedly connected to the ignition wire 21, and a pressure block 222 is fixedly connected to the end of the connecting rope 221. The pressure block 222 is slidably connected to the support frame 223 on the blocking tube 31. A compression spring 224 is arranged between the pressure block 222 and the support frame 223, and a nail 225 is fixedly connected to the side of the pressure block 222 facing the balloon 33.

[0029] When the limiting rod 23 releases the limit on the ignition wire 21, the ignition wire 21 will release the limit on the connecting rope 221. Under the action of the compression spring 224, the pressure block 222 drives the nail 225 to move toward the balloon 33 until the balloon 33 is punctured.

[0030] Furthermore, a guide frame 4 is provided on the safety tube 1 , and the ignition wire 21 is slidably connected to a slide groove on the guide frame 4 .

[0031] Furthermore, the safety tube 1 is provided with a water collection tube 5 corresponding to the position of the blocking tube 31. A cover 51 is detachably connected to the bottom of the water collection tube 5, and the water collection tube 5 is in communication with the interior of the safety tube 1. The cover 51 is threadedly connected to the water collection tube 5. After the balloon 33 ruptures, the water will fall into the water collection tube 5, avoiding retention in the safety tube 1.

[0032] Working Principle: The fuse is passed through the safety tube 1 and then through the annular ring. When the fuse burns through the annular ring of the ignition wire 21, the burning annular ring causes the limit rod 23 to release the limit on the annular ring. When the limit rod 23 releases the limit on the ignition wire 21, the ignition wire 21 releases the limit on the connecting rope 221. Under the action of the compression spring 224, the pressure block 222 drives the nail 225 toward the balloon 33 until the balloon 33 is punctured, allowing the water in the balloon 33 to wet the fuse, preventing it from burning and extinguishing the fire. After the balloon 33 bursts, the water will fall into the water collection tube 5, avoiding being retained in the safety tube 1. This utility model has high safety and can pull the fuse out of the safety tube 1 and then cut it, without having to pass it through the safety tube 1 again. In addition, the use of the balloon 33 is relatively low cost, reducing production costs.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
