Description
Technical Field
The utility model relates to a hardware and tools especially relates to a novel wear-resisting sleeve instrument.
Background
The socket is a common production, maintenance and living tool, the outer part of the socket is cylindrical, and the inner part of the socket is provided with a hexagonal hole or a dodecagonal hole, so that the socket is suitable for screwing bolts or nuts with very narrow or very deep sunken positions. Among the prior art, in order to practice thrift the manpower, realize the quick elasticity of bolt or nut, generally use electric spanner more, adopt the box head coupling spare of different specifications, the realization is carried out the elasticity to the bolt or the nut of different specifications, electric spanner during operation, electric spanner transmission shaft and box head coupling department, sleeve and bolt or nut junction frictional force are great, wearing and tearing take place more easily, cause the condition of smooth silk to appear in the link wearing and tearing easily, lead to sleeve and bolt, the unable normal use of nut, reduce telescopic life, economic benefits is relatively poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses just to prior art exist not enough, provide a novel wear-resisting sleeve instrument.
In order to solve the above problems, the utility model adopts the following technical proposal:
the utility model provides a novel wear-resisting sleeve instrument, includes the body, the body includes overcoat and endotheca, the overcoat is ordinary steel cylinder, is equipped with the two segmentation ladder hexagonal prism holes of UNICOM on the axle center of overcoat, and the endotheca is two segmentation ladder hexagonal prism wear-resisting cermet, and endotheca bottom axle center is equipped with hexagonal column hole, and the endotheca is located the two segmentation ladder hexagonal prism holes of overcoat, and overcoat upper end hexagonal column hole is exposed to the endotheca upper end, and overcoat and endotheca are connected integratively.
The inner diameter of the upper hexagonal prism hole of the outer sleeve is smaller than that of the lower hexagonal prism hole of the outer sleeve, and the outer diameters of the upper hexagonal prism hole and the lower hexagonal prism hole of the outer sleeve are respectively consistent with the outer diameters of the upper hexagonal prism and the lower hexagonal prism of the inner sleeve.
The inner diameter of the hexagonal column hole of the inner sleeve is consistent with the nominal diameter of the standard nut.
The position of the hexagonal prism hole at the upper end of the outer sleeve exposed out of the inner sleeve is provided with a limiting wear-resisting ring, and the limiting wear-resisting ring is cylindrical and is sleeved on the inner sleeve and is respectively connected with the outer sleeve and the inner sleeve into a whole.
Compared with the prior art, the utility model discloses an implement the effect as follows:
a novel wear-resisting sleeve instrument, constitute by ordinary steel overcoat and wear-resisting cermet endotheca, the sleeve is wear-resisting cermet with the link of electric spanner and bolt, nut, long-time work is lower to telescopic each link wearing and tearing, when guaranteeing normal use, has improved telescopic life, economic benefits is better.
Drawings
Fig. 1 is a schematic structural view of a novel wear-resistant sleeve tool according to the present invention;
FIG. 2 is a view taken along the line A in FIG. 1;
fig. 3 is a view from direction B of fig. 1.
Detailed Description
The present invention will be described with reference to specific embodiments.
As shown in fig. 1, 2 and 3, a novel wear-resisting sleeve tool, including body 1, body 1 includes overcoat 2 and endotheca 3, overcoat 2 is ordinary steel cylinder, is equipped with the two segmentation ladder hexagonal prism holes of UNICOM on the axle center of overcoat 2, endotheca 3 is two segmentation ladder hexagonal prism wear-resisting cermet, 3 bottom axles of endotheca are equipped with hexagonal column hole 4, endotheca 3 is located the two segmentation ladder hexagonal prism holes of overcoat 2, 3 upper ends of endotheca expose 2 upper ends hexagonal prism holes of overcoat, and overcoat 2 is connected integratively with endotheca 3, wear-resisting cermet endotheca 3 upper end is connected with electric wrench transmission shaft, the lower extreme is connected with bolt or nut, each link wearing and tearing are less during operation, when guaranteeing normal use, improved telescopic life, economic benefits is better.
The inner diameter of the upper hexagonal prism hole of the outer sleeve 2 is smaller than that of the lower hexagonal prism hole, and the upper hexagonal prism hole and the lower hexagonal prism hole are respectively consistent with the outer diameters of the upper hexagonal prism and the lower hexagonal prism of the inner sleeve 3, so that the tightness of connection between the outer sleeve 2 and the inner sleeve 3 is guaranteed, and the working strength of the sleeve is improved.
The inner diameter of the hexagonal column hole 4 of the inner sleeve 3 is consistent with the nominal diameter of the standard nut, so that the bolts or nuts with different specifications can be conveniently and quickly disassembled and assembled.
The limiting wear-resisting ring 5 is arranged at the position, where the hexagonal prism hole at the upper end of the outer sleeve 2 is exposed out of the inner sleeve 3, the limiting wear-resisting ring 5 is cylindrical and is sleeved on the inner sleeve 3 and is respectively connected with the outer sleeve 2 and the inner sleeve 3 into a whole, so that the electric wrench transmission shaft is ensured to be tightly connected with the sleeve, the electric wrench transmission shaft connecting end is prevented from being worn on the sleeve outer sleeve 2 during working, and the service life of the sleeve is further prolonged.
To sum up, a novel wear-resisting sleeve instrument, by ordinary steel overcoat 2 and wear-resisting cermet endotheca 3 constitution, the link of sleeve and electric spanner and bolt, nut is wear-resisting cermet, long-time work is lower to telescopic each link wearing and tearing, when guaranteeing normal use, has improved telescopic life, economic benefits is better.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
