Abstract
The utility model provides bolt arrangement, including bolt head and screw rod, it is characterized by also including sticking departments, the sticking department is arranged between bolt head and screw rod and is using the screw rod as the annulus of inner circle, the sticking department has a thickness and is integrally formed with the bolt head, the screw rod, the one end of the sticking department far from the bolt head is lock face, radial tooth engaged is evenly arranged on the lock face, all radial tooth engageds are radial centered on the screw rod and extend from the screw rod to the lock face outer edge.Elevator bolt coefficient of friction increases anti-loosening stablizing effect.
Description
Technical field
The utility model relates to fastener areas more particularly to a kind of bolt arrangements.
Background technique
The frictional contact surface of existing bolt arrangement be it is flat, such as vibrate frequent high-speed rail using in the field of high requirement
Whens equal, just locked with the cooperation of two panels lock washer, but nonetheless, due to the knot of bolt frictional contact surface and lock washer
Conjunction face is plane, and coefficient of friction is small, is easy slowly to loosen after frequent vibration, thus worker needs to carry out it frequently to add
Gu just can guarantee the lasting fastening of fastener.
Utility model content
The purpose of this utility model is that providing a kind of bolt arrangement in view of the deficiencies of the prior art.
The utility model provides a kind of bolt arrangement, including bolt head and screw rod, further includes sticking department, and the sticking department is set
Set between bolt head and screw rod and be using the screw rod as the annulus of inner circle, the sticking department have a thickness and with it is described
Bolt head, the screw rod are integrally formed, and the one end of the sticking department far from the bolt head is lock face, on the lock face
It is even to be provided with several radial tooth engageds, all radial tooth engageds it is radial centered on the screw rod and from
The screw rod extends to the lock face outer edge.
Preferably, each described radial tooth engaged has crown, bottom of the tooth, backstop flank and sliding flank, described
Crown and the bottom of the tooth are distributed in the sliding flank two sides, and the sliding flank is tilted from the crown to the bottom of the tooth, institute
State the bottom of the tooth that backstop flank hangs down to the adjacent radial tooth engaged from the crown.
Preferably, the bolt head is outer-hexagonal bolt head, and the outside diameter of the sticking department annulus is greater than described outer six
The external diameter of a circle of the hexagonal of corner bolt head.
Preferably, the bolt head is outer-hexagonal bolt head, the outer circle circumference and the outer-hexagonal of the sticking department annulus
Six faces of bolt head are tangent.
Preferably, the bolt head is hexagon socket head cap screw head, and the outside diameter of the sticking department annulus is greater than six in described
The outside diameter of corner bolt head.
The utility model has the beneficial effects that elevator bolt coefficient of friction, increases anti-loosening stablizing effect.
Detailed description of the invention
Fig. 1 is the utility model first embodiment schematic perspective view.
Fig. 2 is the utility model first embodiment schematic view of the front view.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing.
First embodiment.
Such as Fig. 1-2, a kind of bolt arrangement is provided, for cooperating with lock washer to be fastened.Bolt arrangement includes spiral shell
Bolt head 10, screw rod 20 and sticking department 30, sticking department 30 are arranged between bolt head 10 and screw rod 20 and are with screw rod 20 for inner circle
Annulus, the external margin of sticking department 30 is locked out the outer circle of 30 annulus of portion, and sticking department 30 has a thickness and and bolt head
10, screw rod 20 is integrally formed, and sticking department 30 has a thickness, can be arranged within the scope of 0.8-2mm according to actual needs.At this
In embodiment, bolt head 10 is outer-hexagonal bolt head, and 30 outside diameter of sticking department is greater than the six of 10 outer-hexagonal bolt head of bolt head
The external diameter of a circle in angle.
The one end of sticking department 30 far from bolt head 10 is lock face 31, is evenly arranged with several radials on lock face 31
Tooth engaged 311, all radial tooth engageds 311 are radial centered on screw rod 20 and from screw rod 20 to 31 outside of lock face
Edge extends.
Each radial tooth engaged 311 has crown 3111, bottom of the tooth 3112, backstop flank 3112 and sliding flank
3114(figure is not shown), crown 3111 and bottom of the tooth 3112 are distributed in sliding 3114 two sides of flank, slide flank 3114 from crown
3111 tilt to bottom of the tooth 3112, and backstop flank 3112 hangs down to the bottom of the tooth of adjacent radial inclined-plane tooth engaged 311 from crown 3111
3112。
Second embodiment.
In a second embodiment, bolt head 10 is outer-hexagonal bolt head, the outer circle circumference and outer-hexagonal of 30 annulus of sticking department
Six faces of bolt head are tangent.To which the whole contracting of sticking department 30 is below outer hexagonal bolt head, reduces it and account for area, be suitable for narrow
The fastening in small space.Other structures are identical with the first embodiment.
3rd embodiment.
In the third embodiment, bolt head 10 is hexagon socket head cap screw head, and the outside diameter of 30 annulus of sticking department is greater than interior six
The outside diameter of corner bolt head.Other structures are identical with the first embodiment.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
