Abstract
The utility model relates to a sleeve used for a sleeve spanner. The sleeve comprises a metal base body, an inner nylon sleeve and an outer metal sleeve. The metal base body is connected with a handle of the sleeve spanner, a hexagon through hole is formed in the lower end of the metal base body along the axis, and threads are arranged on the outer surface of the metal base body; the inner nylon sleeve is embedded into the hexagon through hole in the lower end of the metal base body and comprises a hexagon column and a flange step sequentially from top to bottom, the hexagon column is matched with the hexagon through hole in the lower end of the metal base body, a hexagon through hole matched with a nut is formed in the inner nylon sleeve along the axis, and the inner nylon sleeve is fixed to the metal base body by the outer metal sleeve through the flange step. The outer metal sleeve is a cylinder, a circular hole is formed in the bottom face of the outer metal sleeve and matched with the flange step of the inner nylon sleeve, and the outer metal sleeve is connected with the metal base body in a threaded mode. By means of the sleeve, nuts with high requirements for surface plating can be assembled, and damage to the surface plating of the nuts can be reduced.
Description
Technical field
The utility model belongs to general utility tool design field, relates to a kind of sleeve for box spanner.
Background technology
Nut overlay coating is very important on the impact of nut reply external environment; box spanner during as a kind of assembling nut common tool; it can be convenient for changing the assembling that sleeve adapts to different size nut; but usually can find that the sleeve of box spanner has damage in various degree to nut overlay coating in the time using existing box spanner assembling nut; this makes nut lose the protection of coating; thereby make nut be very easy to be subject to the damage of corrosion; this has increased maintenance cost undoubtedly, has caused waste.
Utility model content
Technical problem to be solved in the utility model is: a kind of sleeve for box spanner is provided, is reduced in the damage of nut assembling process middle sleeve to nut overlay coating.
The technical solution of the utility model is: a kind of sleeve for box spanner, is characterized by: described sleeve comprises metallic matrix 1, nylon inner sleeve 2 and metal-coating 3; Described metallic matrix 1 comprises two parts, and upper end is a large cylinder, and lower end is a small cylinder; The upper end of described metallic matrix 1 is connected with the handle of box spanner; The inside, lower end of described metallic matrix 1 has hexagon through hole along axis; There is external screw thread the lower end of described metallic matrix 1, with the screw-internal thread fit of metal-coating 3; Described nylon inner sleeve 2 is embedded in the through hole of inside, lower end of metallic matrix 1; Nylon inner sleeve 2 comprises hexagonal cylinder and flange step from top to down successively; Described hexagonal cylinder matches with the through hole of the inside, lower end of metallic matrix 1; Described nylon inner sleeve 2 is embedded in the through hole of inside, lower end of metallic matrix 1; Described metal-coating 3 is fixed on nylon inner sleeve 2 on metallic matrix 1 by flange step; Described nylon inner sleeve 2 has the hexagonal through hole coordinating with nut along axis; Described metal-coating 3 is a cylinder, and its bottom surface has circular hole, inside has screw thread, and circular hole matches with the flange step of nylon inner sleeve 2; Described metal-coating 3 is threaded with metallic matrix 1.
The beneficial effects of the utility model are: a kind of sleeve for box spanner of the utility model, by nylon inner sleeve is set on metallic matrix, and with metal-coating by the fixation of nylon inner sleeve, can be used for the assembling of the nut that effects on surface coating has higher requirements, contribute to reduce the damage of nut overlay coating.
