Abstract
The utility model discloses an inner hexagon concave-end locking screw. The locking screw consists of inner hexagon (1), a screw stem (2) and a front end (3) and is characterized in that the front end (3) of the inner hexagon concave-end locking screw is provided with a ring-shaped plane (3.1). The inner hexagon concave-end locking screw can be effectively used for locking a shaft sleeve and a shaft.
Description
Technical field
The utility model relate to be used for axle sleeve with the axle between the recessed end Cock screw of the interior hexagonal that is connected and plays the role of positioning.
Background technique
At present, the front end of the recessed end Cock screw of interior hexagonal in the NBS part is very little with axle outer surface area of contact, as shown in Figure 1, therefore is difficult for axle sleeve and shaft locking.
The model utility content
The technical problems to be solved in the utility model is, provide a kind of can be effectively with the recessed end Cock screw of interior hexagonal of axle sleeve and shaft locking.
The technical solution of the utility model is, a kind of recessed end Cock screw of interior hexagonal with following structure is provided, and it is made up of interior hexagonal, screw portion and front end, described in the front end of the recessed end Cock screw of hexagonal be provided with planar annular.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the front end of the recessed end Cock screw of hexagonal is provided with planar annular in described, make that the front end of the interior recessed end Cock screw of hexagonal of the utility model is big with axle outer surface area of contact, so can be effectively with axle sleeve and shaft locking.
Description of drawings
Fig. 1 is the structural representation of the recessed end Cock screw of interior hexagonal in the NBS part.
Fig. 2 is the structural representation of the recessed end Cock screw of hexagonal in the utility model.
Shown in the figure, 1, interior hexagonal, 2, screw portion, 3, front end, 3.1, planar annular.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The recessed end Cock screw of hexagonal is made up of interior hexagonal 1, screw portion 2 and front end 3 in the utility model, and its characteristics are that the front end 3 of the described interior recessed end Cock screw of hexagonal is provided with planar annular 3.1, and concrete structure as shown in Figure 2.
The interior hexagonal 1 of the recessed end Cock screw of interior hexagonal that is provided in the depth ratio NBS part of the interior hexagonal 1 of the recessed end Cock screw of hexagonal in the utility model wants dark, like this, in the fastening the utility model of inner hexagon spanner during the recessed end Cock screw of hexagonal, inner hexagon spanner is difficult for skidding, and can reach the tightening torque index.
