Abstract
The utility model discloses an octagonal plum blossom flange face full thread bolt device comprising a bolt (1) and a screw cap (2), wherein the bolt (1) consists of a bolt head (1.1) and a screw rod (1.2) which are connected; both the bolt head (1.1) and the screw cap (2) are shaped like octagonal plum blossom; the opposite end surfaces of the bolt head (1.1) and the screw cap (2) are flange faces; the device also comprises at least one lock bolt (3) screwed in a screwed hole (6) in the radial direction of the screw cap (2), and at least one groove (4) arranged in the axial direction of the screw rod (1.2) and embedding the lock bolt (3); and the lock bolt (3) and the groove (4) have the same quantity and correspond to each other one by one. The bolt device can prevent the screw cap and the bolt from loosening, and has high work reliability and wide application range.
Description
Technical field
The utility model relates to a kind of hardware fastening, specifically is a kind of anistree plum blossom flanged surface screw bolt device.
Background technique
The anistree plum blossom partial thread bolt device of prior art comprises bolt and nut, and described bolt is made up of the bolt head that links together, screw rod; Described bolt head, nut are anistree plum blossom shape.There is following defective in the bolt device of said structure in the using process of reality: the bolt device of this structure is when the mechanically use of lax activity, as the forklift rocking arm, it is using as axle on the forklift rocking arm, and the rocking arm of forklift always turns round in a kind of high strength, high-revolving environment, therefore in the stronger environment of this vibration, use, nut be easy to and bolt between relatively rotate, even nut and bolt take off fully, thereby cause the rocking arm injury passerby that drops on forklift.In addition, because the face area of bolt head and nut is less, can't use at some the bigger occasion of bolt end face area requirements, thereby its using scope is less.Therefore, the bolts and nuts of the anistree plum blossom flanged surface screw bolt device of existing structure are easy to become flexible, and its functional reliability is lower and using scope is little.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and a kind of anistree plum blossom flanged surface screw bolt device that can prevent that nut and bolt looseness and using scope are wide is provided.
The technical solution of the utility model is, a kind of anistree plum blossom flanged surface screw bolt device is provided, and comprises bolt and nut, and described bolt is made up of the bolt head that links together, screw rod; Described bolt head, nut are anistree plum blossom shape, and the opposing end surface of described bolt head and nut is a flanged surface; It comprises that also at least one the confession that ends unscrew and be located at least together on the screw axial direction that screws in nut radial direction upper screwed hole ends the groove that unscrew embeds, and the described unscrew that ends is equal and corresponding one by one with the quantity of groove.
After adopting above structure, the utility model compared with prior art has the following advantages:
In the anistree plum blossom flanged surface of the utility model screw bolt device, bolt and nut are provided with and end unscrew and groove, ending unscrew during use is embedded in the groove, so just, can prevent nut and bolt looseness, thus when having avoided this bolt device to use on the forklift rocking arm because bolt and nut are taken off drop injury passerby's problem of the rocking arm that causes on forklift.Therefore the bolts and nuts of the anistree plum blossom flanged surface of the utility model screw bolt device are difficult for becoming flexible, and its functional reliability is higher.In addition, because the opposing end surface of bolt head and nut is a flanged surface, therefore can be used in some to the bigger occasion of bolt end face area requirements, its using scope is wider.
As improvement, described nut is provided with two and ends unscrews, and described two to end unscrew be that the center is symmetrically distributed with the central axis of nut; Described screw rod is provided with the twice groove, described twice groove is that the center is symmetrically distributed with the central axis of screw rod, but thisly be symmetrical arranged two of uniform distributions and end the stressed of unscrew, make the functional reliability of the anistree plum blossom flanged surface of the utility model screw bolt device further increase.
As further improvement, described twice groove is respectively equipped with an opening away from an end of bolt head, and the setting of this opening can help the processing of twice groove, thereby reduces the processing cost of the anistree plum blossom flanged surface of the utility model screw bolt device.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of anistree plum blossom flanged surface screw bolt device of the utility model comprises bolt 1 and nut 2, and described bolt 1 is made up of the bolt head 1.1 that links together, screw rod 1.2; Described bolt head 1.1, nut 2 are anistree plum blossom shape, and described bolt head 1.1 is a flanged surface with the opposing end surface of nut 2; It comprises that also at least one the confession that ends unscrew 3 and be located at least together on screw rod 1.2 axial directions that screws in nut 2 radial direction upper screwed holes 6 ends the groove 4 that unscrew 3 embeds, and the described unscrew 3 that ends is equal and corresponding one by one with the quantity of groove 4.
Described nut 2 is provided with two and ends unscrews 3, and described two to end unscrew 3 be that the center is symmetrically distributed with the central axis of nut 2; Described screw rod 1.2 is provided with twice groove 4, and described twice groove 4 is that the center is symmetrically distributed with the central axis of screw rod 1.2.Be that nut 2 is provided with 6, two of two tapped holes and ends unscrew 3 and be spirally connected with two tapped holes 6 respectively, and the width of groove 4 is slightly larger than the only diameter of unscrew 3.When nut 2 when going to corresponding angle, two are ended unscrew 3 and can be embedded in the twice groove 4, just ending unscrew 3 must be corresponding with the position of twice groove 4 on screw rod 1.2 in the position on the nut 2.
Described twice groove 4 is respectively equipped with an opening 5 away from an end of bolt head 1.1.
The utility model is ended unscrew 3 can be 3,4,5,6, and the groove 4 of Pei Heing is 3,4,5,6 roads etc. too with it, otherwise the intensity that influences bolt gets final product; These are all in protection domain of the present utility model.
