Abstract

A new bi-color socket (1). Both ends of a central through-hole (10) thereof are respectively a first socket wrench hole (11) and a second socket wrench hole (12), the specification of the first socket wrench hole is different from that of the second socket wrench hole, and a socket outer diameter on the first socket wrench hole side is greater than that on the second socket wrench hole side. The socket is provided with a front annular groove (21) and a rear annular groove (22) on a socket outer surface on the first socket wrench hole side. A first paint film (31) is coated on a socket outer surface between the front annular groove and the rear annular groove, and a second paint film (32) of which the color is different from that of the first paint film is coated on a groove surface in the front annular groove and the rear part annular groove. The socket is easy to manufacture, has a high percentage of acceptable products, costs a small amount of paint, and has good appearance.

Description

A new two-color sleeve

Technical field

The utility model relates to a two-color sleeve.

Background technique

The sleeve is a commonly used wrench tool. There is a kind of sleeve, which has wrench holes at both ends, and the specifications of the wrench holes at both ends are different. This kind of sleeve can greatly save the number of tools of the kit and provide more complete sleeve specifications. However, when such a sleeve is used, it is difficult for the operator to quickly identify which end wrench hole should be used, which makes the operator feel inconvenient when using it.

Summary of the invention

The technical problem to be solved by the utility model is to provide a new two-color sleeve which is convenient to use and beautiful in appearance. To this end, the utility model adopts the following technical solutions:

A new two-color sleeve having a central through hole at a first socket wrench hole and a second socket wrench hole at two ends of the center through hole, the first socket wrench hole and the second The size of the socket wrench hole is different, and the outer diameter of the sleeve on the side of the first socket wrench hole is larger than the outer diameter of the sleeve side of the second socket wrench hole, characterized in that the sleeve is in the first socket wrench hole The outer surface of the sleeve is provided with a front annular groove and a rear annular groove, and the outer surface of the sleeve between the front annular groove and the rear annular groove covers the first paint film, and the front annular groove The groove surface in the groove and the rear annular groove covers a second paint film different in color from the first paint film.

Based on the above technical solutions, the present invention can also adopt the following further technical solutions:

The paint of the first paint film is also applied to the front annular groove and the rear annular groove, and the second paint film is covered on the groove surface.

The first socket wrench hole is a square wrench hole, and the second socket wrench hole is a hexagonal wrench hole.

By adopting the technical solution of the utility model, the utility model can mark the wrench holes of different specifications at both ends of the sleeve by covering the paint film at one end of the sleeve surface, so that the user can easily distinguish. Moreover, the utility model adopts the front annular groove and the rear annular groove and the paint film thereon as the front and rear boundaries of the paint film on the surface of the sleeve, so that the manufacturing process is easier to carry out, the product quality rate is improved, the paint is excellent, At the same time, the utility model gives the sleeve a color appearance, which makes it easier for the designer to design a sleeve shape with individuality and the manufacturer's own style, which is more attractive to the purchaser and contributes to the sale of the sleeve.

detailed description

Refer to the attached drawings. The novel two-color sleeve 1 provided by the utility model has a central through hole 10, the first socket wrench hole 11 and the second socket wrench hole 12 are respectively at two ends of the through hole, and the specifications of the first socket wrench hole 11 and the second socket wrench hole 12 are different, the specification The difference may be different sizes under the same unit system, or different sizes of different units, or different shapes of the wrench holes, for example, the first socket wrench hole 11 is a square wrench hole, and the second socket wrench hole 12 is a hexagonal wrench hole. .

The sleeve outer diameter D of the first socket wrench hole side is larger than the sleeve outer diameter d of the second socket wrench hole side, and the sleeve is provided with a front ring on the outer surface of the sleeve of the first socket wrench hole side. The groove 21 and the rear annular groove 22, the outer surface of the sleeve between the front annular groove 21 and the rear annular groove 22 covers the first paint film 31, the front annular groove 21 and the rear annular groove The groove surface in the groove 22 covers the second paint film 32 which is different in color from the first paint film.

For the color intersection of the front annular groove 21 and the rear annular groove 22, the first paint film 31 and the second paint film 32 may be directly butted.

Alternatively, the first paint film is first painted, and the paint of the first paint film 31 is applied to the front annular groove 21 and the rear annular groove 22, and then the second paint film 32 is covered on the groove surface. Alternatively, it is also possible to first paint the second paint film 32, and when applying the paint of the second paint film 32, apply it to the surface of the sleeve between the front annular groove 21 and the rear annular groove 22, and then The sleeve surface between the front annular groove 21 and the rear annular groove 22 covers the first paint film 31. Among the two methods, the former is better, the paint processing is easy, the surface of the sleeve is smoother and smoother, and the appearance is more beautiful.

When the surface of the sleeve between the front annular groove 21 and the rear annular groove 22 covers the first paint film 31, the first paint film 31 is allowed to partially penetrate the air 33 or further apply a color of other colors in the transparent space. Membrane to form the product logo, model, decorative pattern and other graphic.
