Description

Technical Field

[0001] The utility model relates to the technical field, and specifically relates to a device for detecting the ignition time of fireworks. Background Technique

[0002] In order to control the explosion risk, prevent accidental injuries and ensure the visual effect, during the production and manufacture of fireworks, it is necessary to use a detection device to detect the ignition time of the fireworks to improve the quality of fireworks products. However, when the existing detection devices detect the ignition time of fireworks, most of them still record the initial ignition time and the end time of the fuse of the fireworks. This can only detect the total time of the fuse and the average speed. However, due to the differences in the purity and particle size of the materials at various parts inside the fuse during the processing of the fireworks fuse, the ignition time at various parts of the fuse is different, which makes the existing detection devices unable to detect the ignition speed at various parts of the fuse, thus affecting the detection effect. For this reason, we propose a device for detecting the ignition time of fireworks. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a fire ignition time detection device for fireworks, including a base 1. A concave cavity 11 is opened on one side of the upper end of the base 1. A plurality of mutually attached temperature sensors 12 are fixedly installed at equal intervals in the concave cavity 11. A wire 13 is fixedly installed at the outer end of each temperature sensor 12. A scale 14 is provided on the other side of the upper end of the base 1. Two symmetrically arranged positioning plates 2 are slidably installed on the upper end of the base 1. The positioning plates 2 are semicircular. Moving plates 21 are fixedly installed at both ends of the two positioning plates 2. Rotating disks 23 are rotatably installed on both sides of the upper end of the base 1. The upper ends of the rotating disks 23 are slidably connected to the moving plates 21 on both sides. A disc spring 24 is provided between the rotating disks 23 and the positioning plates 2.

[0021] Working principle: When in use, the fireworks fuse is unfolded and placed on the upper end of the base 1. The two moving plates 21 are adjusted inward. Through the two moving plates 21, the fireworks fuse can be clamped and positioned. Since the moving plates 21 are made of transparent material and cooperate with the scale 14, the length of the fireworks fuse can be detected.

[0022] One end of the fireworks fuse is ignited. Since the fuse is in contact with each temperature sensor 12, when the fuse burns, the temperature of the ignited fuse can be detected through each temperature sensor 12. Thus, both the ignition time of the fuse can be detected, and referring to the detection width of the temperature sensor 12, the ignition speed of each part of the fuse can be detected, so as to evaluate the purity and particle size of the materials at each part of the fireworks fuse.

[0023] As a further description of the above technical solution: A first limit slide groove 223 is provided at the upper end of the base 1, and a first limit slider 211 slidably connected to the first limit slide groove 223 is fixedly installed at the lower end of the movable plate 21; A limit cavity 22 is provided at the upper end of the positioning plate 2, a limit rotation groove 221 is provided on the upper side of the inner cavity of the limit cavity 22, and a limit rotation block 231 rotatably connected to the limit rotation groove 221 is fixedly installed on the periphery of the rotating disk 23; A second limit slide groove 212 is provided at the lower end of the movable plate 21, a second limit slider 233 slidably connected to the second limit slide groove 212 is fixedly installed at the upper end of the rotating disk 23, and a rotating handle 232 is fixedly installed in the middle of the upper end of the rotating disk 23; A movable block 234 is fixedly installed at the lower end of the rotating disk 23, a positioning hole 235 radially arranged is provided in the middle of the movable block 234, the middle of the disc spring 24 is inserted into the positioning hole 235, and the periphery of the disc spring 24 is clamped with the positioning block 222 fixed on the inner wall of the limit cavity 22.

[0024] Specifically, before the lead is installed, the rotating disk 23 is rotated by turning the rotating handle 232. Under the limitation of the movement direction of the movable plate 21 by the sliding connection between the first limit slider 211 and the first limit slide groove 223 on the base 1, the rotating rotating disk 23 can drive the two positioning plates 2 to expand outwards through the sliding connection between the second limit slider 233 and the second limit slide groove 212, facilitating the installation of the lead between the two positioning plates 2.

[0025] After the lead is installed, the rotating handle 232 is released. Under the action of the disc spring 24 restoring its deformation, the rotating disk 23 can be driven to rotate reversely, thereby driving the two positioning plates 2 to contract inwards, achieving the effect of clamping the lead.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
