Split firing pin

Abstract

This utility model relates to the technical field of ignition needle devices, specifically to a split-type ignition needle, including a plastic sleeve. An ignition wire is fixed to the bottom end of the plastic sleeve. A side groove is formed on the side wall of the plastic sleeve. A needle body one is disposed inside the plastic sleeve. The needle body one includes a needle structure, a spring piece fixed to the outside of the needle structure, and a shell fixed to the outside of the spring piece. A threaded hole is formed through the needle structure, and a needle body two is engaged and fixed within the threaded hole. Because the spring piece structure is an elastic structure and is L-shaped, the bottom of the spring piece can be locked in the side groove. The bottom of the needle structure is connected and in contact with the positioning ring structure, thus fixing the needle body one to the plastic sleeve structure. Finally, the needle body two structure can be engaged and fixed with the middle of the needle body structure through a spiral structure, achieving a combined connection of the three structures and a good connection effect.

Description

Technical Field

[0001] This utility model relates to the technical field of ignition needle devices, specifically to a split-type ignition needle. Background Technology

[0002] The existing ignition needle installation structure of gas stoves is generally located at the lower part of the ignition needle. A spring is inserted into the lower part of the ignition needle, and the upper end of the spring contacts and abuts against the burner. The lower side wall of the ignition needle has an annular groove, in which a retaining spring is inserted. The retaining spring abuts against the lower end of the spring, thus fixing the ignition needle. This installation method is very troublesome during assembly and maintenance. In addition, during the manufacturing process, the ignition needle is usually made of ceramic material. The mounting hole for the ceramic ignition needle in the gas stove is usually machined to be slightly larger than the diameter of the ignition needle to facilitate the installation of the ceramic ignition needle. However, this installation method can cause the ignition needle to wobble in the mounting hole, resulting in the ignition needle breaking during transportation and handling. Replacing the ignition needle in such cases is also very troublesome. Utility Model Content

[0003] Technical problems to be solved

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a split ignition needle, which can effectively solve the problems in the existing technology.

[0005] Technical solution

[0006] This utility model provides a split ignition needle, including a plastic sleeve, an ignition wire fixed to the bottom end of the plastic sleeve, a side groove on the side wall of the plastic sleeve, a needle body one disposed inside the plastic sleeve, the needle body one including a needle body structure, a spring piece fixed to the outside of the needle body structure and a shell fixed to the outside of the spring piece, a threaded hole through the needle body structure, and a needle body two engaged and fixed inside the threaded hole.

[0007] Furthermore, multiple sets of side grooves are equidistantly formed on the outer side of the plastic sleeve, and the size of the side grooves is adapted to the bottom size of the spring piece.

[0008] Furthermore, the spring sheet has an L-shaped structure, and the top end of the spring sheet is fixed to the outside of the needle body structure.

[0009] Furthermore, the outer shell is a hollow tubular structure with an I-beam shape, and the ignition wire and the needle body structure are kept in contact by a positioning ring.

[0010] Furthermore, there is a gap between the inner wall of the outer shell and the outer wall of the needle structure, and the top end of the spring is fixed to the top end of the needle structure, and the spring is a spring structure.

[0011] Furthermore, the top of the needle body two is trumpet-shaped, with a smaller top and a larger bottom.

[0012] Beneficial effects

[0013] This utility model, through its modular structure, allows the user to first place the ignition wire inside the plastic sleeve and then fix the positioning ring to the ignition wire, thus securing the ignition wire. Next, the needle body structure is secured by its internal spring and side groove. Because the spring is elastic and L-shaped, its bottom can be engaged in the side groove. The bottom of the needle body structure connects with the positioning ring structure, thus securing the needle body to the plastic sleeve structure. Finally, the needle body structure is secured by a spiral structure engaging with the middle of the needle body structure, achieving a combined connection of the three structures and a good connection effect.
