Description
Technical field
The present invention relates to a kind of die nut, espespecially a kind of Spanner with hexagonal ball end.
Background technology
With reference to Figure 19, it is a kind of schematic diagram of existing die nut.Spanner 9 one end forms ball head 91, and form a ring neck 92 in adjoining ball head 91 inside circumference, wherein ball head 91 peripheral ring establishes formation one hex surface 93, and be inwardly provided with a storage tank 94 in hex surface 93 more than one of them, the notch of this storage tank 94 is slightly less than groove body, and to be outwards sequentially provided with inside a spring 95 and one by spring 95 pushing tow and the little steel ball 96 of storage tank 94 is exposed in outside in interior; Utilize little steel ball 96 surface round and smooth and can the elasticity structure that enters to push away, when utilizing ball head 91 oblique cutting to enter the hexagon ring of spiral lock, there is effect of convenient turnover, and because little steel ball 96 can fill up hexagon ring because using the space of wearing and tearing, can be more laborsaving and not easily make hexagon ring wear and tear when making rotation.
Aforementioned patent relies on spring and little steel ball top to be located at hexagon ring, reaches the object that ball head can be engaged in hexagon ring.Such design must process a storage tank at the hex surface of ball head, and spring and little steel ball is assembled in storage tank.Compared to traditional Spanner with hexagonal ball end, many processing storage tanks, prepare the program of spring and little steel ball and assembling.Therefore, such design has the disappearance that cost increases and process velocity is slow.
Moreover, this design utilizing spring and little steel ball top to be located at hexagon ring, really do not improve the slippage problems of hex surface and hexagon ring, die nut is only provided with single group of spring and little steel ball, therefore single mask only can be provided to have preferably top to establish effect, and the top of little steel ball is established and cannot be solved the disappearance of skidding completely.
And little steel ball is located at hexagon ring with the mode top of point cantact, when die nut is used in special angle and favours hexagon ring, little steel ball very likely can depart from hexagon ring, and makes little steel ball push up establishing hexagon ring.
Because the disappearance of above-mentioned existing structure, the present inventor invents a kind of Spanner with hexagonal ball end, and it can overcome all shortcomings of above-mentioned existing structure.
Summary of the invention
The disappearance that the present invention exists for solving background technology, and provide a kind of Spanner with hexagonal ball end can solve the disappearance of prior art.
For achieving the above object, the technical solution used in the present invention is:
A kind of Spanner with hexagonal ball end, its one end forms a bulb end, this bulb end can drive to be driven, this bulb end has a virtual work portion, this virtual work portion can contact with to be driven, this bulb end comprises first cambered surface, this first cambered surface is shaped at least one recess and at least one bite, this recess is adjacent with this bite, this bite and this virtual work portion are coplanar, this recess is recessed compared to this virtual work portion, and this bite can increase the frictional force between this bulb end and to be driven.
This recess and this bite are directly integrally formed in this bulb end.
This bulb end is provided with a maximum outside diameter, and this recess is by this maximum outside diameter, and this recess and this maximum outside diameter joint can provide to be driven of the driving that this bulb end is vertical.
This first cambered surface is shaped several recess, and the distance between this each recess is not equal.
This recess and this bite are arranged in parallel.
This first cambered surface comprises a first end and second end, this recess is strip, the two ends of this recess are respectively towards the first end of this first cambered surface and the second end of this first cambered surface, and length to be driven the angle that swing relative to this bulb end that this recess extends is proportional.
This first cambered surface comprises a first end, the second end, first side and second side, this recess is oblique line shape, the one end of recess in oblique line shape is towards the first end of this first cambered surface and the first joint, side, and the other end of the recess in oblique line shape is towards the second end of this first cambered surface and the second joint, side.
This recess is in staggered oblique line shape.
This recess is point-like.
The rounded recess of this recess.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention relies on when rotating the bulb end of this Spanner with hexagonal ball end, because two of bite contact surfaces force in drive hole, and can reach effect of better occlusion.This recess can increase the quantity of the contact surface of this bite and drive hole and improve slippage problems.
The present invention increases the quantity of contact surface by means of this recess and bite, this recess and bite can be processed and directly be completed, and making Spanner with hexagonal ball end can meet the requirement of cost and process velocity without the need to additionally installing other assembly, the present invention really has cost compared to traditional Spanner with hexagonal ball end and reduces, without the need to the fast advantage of assembling and process velocity.
The present invention relies on bulb end to be provided with most bite, and therefore when the bite of skidding departs from drive hole, the bite also having other can be attached at drive hole.Because multiple contact surfaces of bite force in drive hole, and can reach effect of better occlusion.
