Description

Mars plug sleeve

This creation relates to the field of tools, and in particular to a magnetic sleeve suitable for disassembly and/or assembly of Mars plugs.

Conventional sleeve tools do not have a magnetic function and can perform the removal or assembly of polygonal bolt heads or nuts.

The well-known sleeve structure, which is mostly a long cylinder, has a corner hole (usually a four-corner hole) for connecting a square column of an electric or hand tool such as a wrench or a post. The other end of the sleeve forms a hexagonal hole that is sufficient to fit over the hexagonal section of the spark plug.

When the electric or manual tool drives the sleeve to rotate, the hexagonal section is forced to drive the spark plug to rotate in the same direction as the sleeve, and the disassembly operation of the spark plug is completed. When the sleeve is removed, the Mars plug drops from the sleeve to the ground, even rolling down a narrow gap, which is not conducive to picking up.

Similarly, when the new Mars plug is filled into the sleeve and the sleeve is to be reversed for screwing, the Mars plug is released from the sleeve by gravity, and the Mars plug must be supported by one hand, and the electric or hand tool is held by the other hand. It is very inconvenient to perform maintenance work smoothly.

Therefore, a magnetic sleeve is available on the market and becomes a savior for maintenance personnel. It can quickly and easily perform the replacement work of Mars.

The magnetic sleeve disclosed in the Taiwan Patent No. M524767 discloses that a magnetic seat is tightly assembled in a sleeve. The magnetic seat has a magnetic ring, and the magnetic ring is embedded in a hexagonal seat. The hexagonal seat has six outer sides, and each outer side is divided into two parts: a plane section and a slope section. The plane The segment ridges a convex portion for contacting the wall surface inside the sleeve. A groove is formed at the corresponding convex portion of the inclined surface portion, and the inclined surface portion is allowed to be pressed and deformed in the direction of the groove.

Although, it solves the shortcomings of Mars plugs falling from the sleeve. However, the construction of this magnetic sleeve is quite complicated, resulting in high production costs, which is not conducive to market competition.

Therefore, how to improve the structure of the Mars plug is an urgent problem to be solved in this creation.

In view of this, the main purpose of the Mars plug sleeve provided by the present invention is to adopt a cassette structure to match the pressing structure, reduce the production cost, and effectively solve the drawback that the Mars plug is dropped from the sleeve.

Due to the above object, the Mars plug sleeve of the present invention comprises: a sleeve having a latching portion and a hexagonal hole having a multi-faceted inner side forming a straight groove at the abutment of the inner side of the inner side The clamping portion is formed on the inner side around the hexagonal hole; a magnetic seat has a magnetic ring, a latching member and a hexagonal seat, the hexagonal seat having an inner hole for allowing the magnetic ring to be embedded in the wall around the inner hole The latch member is configured to pass through the outer edge of the hexagonal seat and the angular groove in the circumferential direction.

When the magnetic seat is inserted into the hexagonal hole of the sleeve, the depth of the groove on the outer side of the hexagonal seat is shallower than the depth of the angular corner, and the buckle is partially beyond the outer edge of the hexagonal seat, and the concave and convex fits on the inner side of the hexagonal hole to make the magnetic The seat is combined with the sleeve.

Wherein, the hexagonal seat has a plurality of pressing portions which are raised at the corners. When the magnetic seat is inserted into the hexagonal hole of the sleeve, the pressing portion is pressed against the corresponding straight groove so that the outer edge of the hexagonal seat faces the inner side of the sleeve.

In this way, the Mars plug sleeve of the present invention not only has a simple function shape of the hexagonal seat, but also relatively reduces the production cost, and can also effectively solve the Martian plug by the card structure and the forced structure. The drawback of the sleeve falling.

Then, based on the detailed description of the related embodiments, the techniques, means and functions employed are described. It is believed that the above objects, structures and features of the present invention can be obtained from a deep and specific understanding.

Referring to Fig. 1, a specific structure of a preferred embodiment of a spark plug sleeve is illustrated. A sleeve 10 is combined with a magnetic base 20.

In Figures 1 and 3, the sleeve 10 has a force receiving section 12 and a force applying section 14, the force receiving section 12 and the force applying section 14 being at different ends of the sleeve 10. In this embodiment, the force receiving section 12 is a square hole (see FIG. 5), and can be connected to a square pole of a manual or electric tool such as a wrench or a post for receiving an external force to perform a locking or unscrewing operation. In some embodiments, the force-bearing section 12 is a square post (not shown) that can be combined with a square hole of a manual or power tool such as a wrench or post.

The sleeve 10 also has a latch portion 16 and a hexagonal hole 18. The hexagonal hole 18 is recessed to a certain depth of the force applying section 14, and has a six-sided inner side 11 and six straight straight grooves 13, each straight groove 13 being adjacent to the inner side 11. In the present embodiment, the latch portion 16 is a groove in which the groove is formed in the circumferential direction around the inner side 11 and the straight groove 13 around the hexagonal hole 18.

In the first and second figures, the magnetic base 20 has a magnetic ring 22, a latching member 24 and a hexagon. Block 30. The hexagonal seat 30 has an inner hole 31 in the center thereof, and a wall 33 is formed in the wall around the inner hole 31 to allow the magnetic ring 22 to be embedded in the recess 33. The hex seat 30 also has a six-sided outer edge 34 and a plurality of urging portions 36 that are planar and that are joined together to form six corners 38. Each of the pressing portions 36 is slanted and embossed at a corresponding corner 38. The pressing portion 36 has a reduced end 37 and an expanded end 39 that slope from the expanded end 39 toward the reduced end 37 and intersect the corner 38 to form an angle 35.

In the present embodiment, the latching member 24 is an O-ring that is received in a groove 32 that passes through the outer edge 34 of the hex seat 30 and the rib 38 in the circumferential direction. In some embodiments, the latch member 24 can be a C-ring.

As shown in Figures 3 and 4, when the magnetic base 20 is inserted into the hexagonal hole 18 of the sleeve 10, the depth of the groove 32 at the outer edge 34 of the hexagonal seat 30 is shallower than the depth of the corner 38, and the restriction member 24 is partially beyond the hexagonal seat. The outer edge 34 of the 30 is fitted to the latch portion 16 of the inner side 11 of the hexagonal hole 18 to join the magnetic base 20 and the sleeve 10.

Secondly, when the magnetic base 20 is inserted into the hexagonal hole 18 of the sleeve 10, the pressing portion 36 is urged against the corresponding straight groove 13, so that the outer edge 34 of the hexagonal seat 30 faces the inner side 11 of the sleeve 10. In other words, when the magnetic base 20 is coupled to the hexagonal hole 18 of the sleeve 10, the expanded end 39 is close to the opening of the hexagonal hole 18, and the reduced end 37 faces the depth of the hexagonal hole 18.

In Fig. 5, a spark plug 40 has a conductive end 42 and an ignition end 44. Between the conductive end 42 and the firing end 44, there is a hex section 46 and a ridge 48 which is located at the conductive end 42 and the ridge. Between the 48.

The conductive end 42 passes through the magnetic ring 22 and continues deep into the hexagonal hole 18 of the sleeve 10 until the raised portion 48 abuts the opening of the hexagonal hole 18. At this point, the magnetic base 20 attracts the metal portion of the spark plug 40, causing the spark plug 40 to be displaced in synchronism with the sleeve 10 without fear that the spark plug 40 will disengage from the magnetic base 20. The hexagonal hole 18 of the sleeve 10 surrounds the periphery of the hexagonal section 46. The hexagonal section 46 and the inner edge 11 of the hexagonal hole 18 are engaged with each other, so that the spark plug 40 can be driven by the sleeve 10 to rotate in the same direction, and smoothly executed. Unload or lock operation.
