Description

Mars plug sleeve structure

The invention relates to a Mars plug sleeve structure, in particular to a Mars plug sleeve structure, which is provided with a body, a snap ring and a clamping member, and the card member is first combined with the snap ring and then pressed into the body. In the third through slot, the clamping member is provided with a clip and a clamping portion, and the clamping portion is clamped against the surface of the insulator to have an anti-off function.

The conventional Mars plug sleeve structure, such as the US Patent No. 5960682, that is, Taiwan Bulletin No.: 372212, a Mars plug, consisting of the following three elements (A), (B), and (C); a matching portion of the Mars plug 3 for inserting the spark plug 3 is formed on the opposite side of the angled wrench body 1 of the operation portion 2 provided with the tip end portion of the handle; (B) the Mars plug 3 is embedded The bottom surface of the recessed portion 4 is fitted with a toroidal surface provided on the bottom surface of the fitting recess 4 and a plurality of flexures extending upward from the edge of the annular surface to contact the inner wall surface of the fitting recess 4 The Mars plug 3 fixing members 5 of the leaf springs 5b and 5c; and (C) a guide member 6 having a low hardness such as brass which is in contact with the spark plug 3 is inserted into the bottom of the fitting recess 4.

However, the lack of structure of this patent is based on:

1. There is no joint structure between the fixing member 5 and the guiding member 6. As shown in the second figure, the fixing member 5 should be first disposed in the fitting recess 4, and the guiding member 6 is further disposed in the fitting recess. 4, the guiding member 6 is pressed against the fixing member 5, but the inner diameter of the fitting recess 4 is not large, and the fixing member 5 and the guiding member 6 are respectively disposed in the fitting recess 4, and the two-step assembly system More troublesome.

2. If the fixing member 5 and the guiding member 6 are assembled before the body 1 and then pressed into the fitting recess 4, the fixing member 5 and the guiding member 6 have no combined structure, and the hand needs to be fixed. The member 5 is pressed into the fitting recess 4 without being separated from the two members of the guiding member 6, and the operation is troublesome.

3. When the fixing member 5 is assembled in the fitting recess 4, the outer circumferential surface of the fixing member 5 and the inner circumferential surface of the fitting recess 4 should be tightly fitted. Otherwise, the fixing member 5 may be used after the spark plug is used for a period of time. The fixing member 5 is made of a metal material. Under the tight fitting structure, the fixing member 5 is assembled in the fitting recess 4 to be frictional. If it is rubbed, the fixing member 5 or the embedded member is embedded. If the surface coating of the recessed portion 4 is worn away, there will be rusting.

In view of the structure of the above-mentioned U.S. patent case, the present inventors have accumulated many years of experience in the manufacture of the Mars plug sleeve, and have finally obtained the present invention.
