Description

TECHNICAL FIELD

[0001] The utility model relates to a clamp for firework lead wire ignition. BACKGROUND

[0002] In the prior art, in order to ignite fireworks, a remote ignition device is used to control the heating of the heating wire through radio control technology, thereby igniting the lead wire of fireworks. In order to facilitate operation, the lead wire is generally fixed on the clamp to contact the heating wire. For example, a Chinese patent document with the application publication number CN112197292A discloses a "remote ignition device used on lead wire", which includes an ignition device and a remote controller that can remotely ignite the lead wire by the ignition device. The remote controller is equipped with a wireless transmitter and a remote switch. The ignition device includes a clamp holder and a clamp plate. The clamp plate is hinged to the clamp holder through a hinge shaft. The two ends of the clamp plate form a clamping end A and an operating end, respectively. The clamp holder is provided with a clamping end B corresponding to the clamping end A. The ignition device further includes a reset member for resetting the clamp plate so that the clamping end A and the clamping end B are clamped tightly. The clamp holder is equipped with a main control circuit board, a main control power supply, and a wireless receiver. The clamping end B is provided with a heating wire. The main control power supply, the wireless receiver, and the heating wire are electrically connected to the main control circuit board. A main control switch is also installed on the clamp holder. When the main control switch is turned on, the wireless receiver can cooperate with the wireless transmitter to achieve the electrification of the heating wire. Through the hinged cooperation of the clamp plate and the clamp holder, the positioning of the lead wire for ignition can be achieved.

[0003] The disadvantage of the prior art is that the clamp clamping the lead wire is easily burned by the heating wire, and the heating wire of the existing device is difficult to replace, resulting in the entire remote ignition device being discarded. UTILITY MODEL CONTENT

[0023] Referring to the drawings, a specific structure of the present application is shown. It is a fireworks lead wire ignition fixture convenient for replacing the wearing parts, which is generally used for the remote control igniter of fireworks. It comprises a clamping seat 2 and a clamping plate 3 hinged through a hinge shaft 1, the hinge shaft 1 of the clamping plate 3 is respectively provided with a clamping end A 4 and an operating end 5 on both sides, the clamping seat 2 is provided with a clamping end B 6 corresponding to the position of the clamping end A 4, and further comprises a reset member for resetting the clamping plate 3 so that the clamping end A 4 and the clamping end B 6 remain in the clamping state, and the reset member is a torsion spring installed on the hinge shaft 1 in the example (not shown in the drawing).

[0024] In operation, the operating end 5 is pressed to overcome the elastic force of the torsion spring so that the clamping end A 4 and the clamping end B 6 are opened, the lead wire (not shown in the drawing) is put in, the operating end 5 is released, the torsion spring drives the clamping plate 3 to reset, the clamping end A 4 and the clamping end B 6 clamp the lead wire to make it contact and abut against the heating wire 7, and the heating wire 7 ignites the lead wire after being electrified. This is the general working process of the igniter, which will not be described in detail.

[0025] In the example, the clamping end B6 is fixedly provided with the circuit board 8, and the circuit board 8 is provided with two first electrical contacts 801; the heating wire 7 is installed on the base 701, and the base 701 is provided with two second electrical contacts 702 of the heating wire 7 on the bottom surface; the second electrical contacts 702 are provided corresponding to the first electrical contacts 801. The base 701 is sleeved in the positioning frame 9, and the positioning frame 9 is detachably installed above the circuit board 8 so that the two second electrical contacts 702 are respectively in abutment with the two first electrical contacts 801 to be electrically connected. The advantage is that after the heating wire 7 is burned out, the positioning frame 9 can be conveniently removed, and after the heating wire 7 and the base 701 are replaced, the positioning frame 9 is reinstalled, so that the replacement of the vulnerable parts is conveniently completed to facilitate reuse.

[0026] In the example, the specific manner in which the positioning frame 9 is detachably installed above the circuit board 8 is shown: the clamping seat 2 on one side of the circuit board 8 is provided with a bayonet 10, and the clamping seat 2 on the other side of the circuit board 8 is provided with a threaded hole 11, and the bayonet 10 and the threaded hole 11 are respectively located on opposite sides (such as the left and right sides shown in the figure) of the circuit board 8. One side of the positioning frame 9 is provided with a clamping bolt 12 corresponding to the bayonet 10, and the other side of the positioning frame 9 is provided with a positioning hole 13 corresponding to the threaded hole 11.

[0027] In the example, the positioning frame 9 is provided with a lead fixing groove 901 on the front and rear sides. This makes it more convenient and accurate to stably contact the lead with the heating wire 7, thereby improving the reliability and convenience of the ignition work.

[0028] In the example, the base 701 is provided with a limiting port 703 on both sides, and the positioning frame 9 is provided with a limiting edge 902 on the inner wall of the frame body on both sides. The limiting edge 902 is provided corresponding to the limiting port 703, and in the example, the limiting edge 902 is located below the lead fixing groove 901. The base 701 is pushed into the frame body from below the positioning frame 9, and the limiting edge 902 is inserted into the limiting port 703, thereby improving the convenience of base installation and the reliability of positioning.

[0029] During installation, after the base 701 is installed in the positioning frame 9, the two clamping ends A and B are opened by pressing the operation end 5, the clamping bolt 12 is inserted into the bayonet 10 by pushing the positioning frame 9, the clamping plate is reset by releasing the operation end 5, and the threaded hole 11 and the positioning hole 13 are connected by the bolt 14 by inserting the screwdriver 16 into the operation hole 15. During disassembly, after the bolt 14 is loosened and removed, the positioning frame 9 can be pulled out by pressing the operation end 5. The positioning is reliable and the disassembly and assembly are convenient.

The embodiments do not describe all the details exhaustively, and also do not limit the utility model to only the specific embodiments described. Obviously, according to the content of the specification, many modifications and changes can be made.
