Description

Technical Field

[0001] The utility model relates to the technical field of spark plugs, and more particularly to an engine spark plug with a reinforced structure. Background Art

[0002] The spark plug is an important component of the gasoline engine ignition system. It can introduce high voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wire nut, an insulator, a wire screw, a center electrode, a side electrode and a shell. The side electrode is welded to the shell. The spark plug is generally installed inside the fastening sleeve. The fastening sleeve drives the spark plug into the installation position of the engine, and then the fastening sleeve is rotated to drive the spark plug to rotate into the engine.

[0003] Among them, after searching, it was found that the patent application number CN202322629637.4 discloses an engine spark plug with a reinforced structure, including a shell, a mounting frame and a movable rod. A nut is installed on the outside of the shell, and a mounting frame is symmetrically installed on the back of the nut. A threaded rod is installed through the back of the mounting frame, and movable rods are movably installed through both sides of the mounting frame. A second oblique block is installed at one end of the movable rod, a third spring is installed on the front of the mounting plate, and a movable plate is installed at one end of the third spring.

[0004] When this structure is in use, the spark plug is placed inside the fastening sleeve, and then the threaded rod is rotated to drive the first inclined block to move forward. The first inclined block can squeeze the second inclined block outward by moving forward, and the second inclined block can squeeze the inner wall of the fastening sleeve by moving outward, thereby ensuring the stability of the connection between the spark plug and the fastening sleeve and preventing the spark plug from sliding inside the fastening sleeve. However, when this structure is ignited, the arc on the motor is easy to spread, which can easily cause ignition failure. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an engine spark plug with a reinforced structure, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The present invention is implemented as follows. The present invention provides the following technical solutions: an engine spark plug with a reinforced structure comprises a support pad, wherein a connecting assembly is provided on the support pad;

[0009] It can be seen that in the above technical solution, each of the first reinforcing electrode and the second reinforcing electrode transmits the arc toward one end of the central inner column through the pin for connection, which can effectively prevent the arc from leaking out and avoid ignition failure.

[0010] Optionally, in a possible embodiment, a locking pressure ring is provided on the outer side of the first reinforcing locking nut, a second reinforcing locking nut is provided at the bottom of the support pad, the locking pressure ring is threadedly connected to the first reinforcing locking nut, the second reinforcing locking nut is communicated with the connecting sleeve, the second reinforcing locking nut is internally threadedly connected to an extension column, one end of the extension column passes through the second reinforcing locking nut and extends into the second reinforcing locking nut, a docking joint is provided on the top of the extension column, the docking joint is located at the bottom of the central inner column, a plug-in cavity is provided on the second reinforcing locking nut, the plug-in cavity matches the docking joint, the plug-in cavity and the docking joint are plugged and fixed, a protective sleeve is provided on the outside of the connecting sleeve, and a plurality of boosting blocks are provided on the outside of the protective sleeve;

[0011] It can be seen that in the above technical solution, the center inner column and the pin are easily plugged into the device through the plug-in cavity to limit the joint, thereby improving the convenience of the device during installation. The device uses the second reinforced locking nut and the extension column as designated points, and positions the second reinforced locking nut and the extension column through the fastening sleeve on the engine to ensure the stability of its installation.
