Abstract

The utility model relates to a tetragonal full-thread bolt device which comprises a bolt and a nut which is matched with the bolt. The bolt is a t tetragonal bolt and the nut is a tetragonal nut. The screw of the bolt is fully provided with threads. At least one groove which extends along the axial direction of the screw is arranged on the screw. At least one screw hole is arranged on the side wall of the nut. A stop screw which is matched with the groove and can be used to position the nut is arranged in the screw hole. In practical use, after the bolt and the nut are screwed together, the stop screw is screwed into the screw hole on the side wall of the nut and the end section of the screw ejects against the groove on the bolt. Thereby, the nut cannot be turned upward and downward in any application places, and the situations that the nut gets loose, falls off and the like can be avoided.

Description

Four jiaos of screw bolt devices
Technical field:
The utility model relates to fastener areas, relates in particular to a kind of four jiaos of screw bolt devices.
Background technique:
The conventional bolt device comprises screw bolt and nut, should use occasion at some, bolt device is to play the effect that two parts are fastenedly connected, at this moment only screw bolt and nut need be matched to tighten and get final product, and in some other occasion, also may need certain clearance between two parts that bolt device connects, so that the circumferential rotation between two parts, but no matter be in above-mentioned which kind of occasion, after matching, screw bolt and nut all require the invariant position of nut just can be implemented in application target in each occasion, and in the actual using process, the nut in traditional bolt device can take place loosening mostly or come off, and is difficult to satisfy the actual requirement of using.
The model utility content:
For solving above-mentioned technical problem, the utility model provides the difficult four jiaos of screw bolt devices that become flexible or come off of nut in a kind of actual using process.
The technical solution of the utility model is, a kind of four jiaos of screw bolt devices with following structure are provided, and it comprises bolt and the nut that matches with it, and described bolt is four angle head bolts, described nut is a tetragonal nut, and the screw rod of described bolt all is provided with screw thread; Described screw rod is provided with at least one groove that extends along screw axial, and the sidewall of described nut is provided with at least one screw, and being provided with in the described screw matches with groove merges backing-up screw with the nut location.
As improvement, the end face of the axial through bolt afterbody of described groove.
As further improvement, the groove on the described screw rod is two, and described two grooves are symmetrical arranged along the axis of screw rod, and described screw also is two and is symmetrical arranged along the axis of screw that described backing-up screw is two.
After adopting said structure, the utlity model has following advantage:
On the screw rod of four jiaos of common screw bolts, groove is set, and the nut that matches with it is the sidewall of tetragonal nut and nut screw is set, when reality is used, after screw bolt and nut screws, again backing-up screw is screwed in the screw of nut sidewall and the latter end of screw is against in the groove on the bolt.Like this, no matter be to use in which kind of occasion, nut all can not rotate up and down, also just problem can not take place or come off etc. loosening, and the end face of the axial through bolt afterbody of groove is for ease of processing.And the groove on the bolt is two, and is symmetrical arranged along the axis of screw, and is corresponding, the screw of nut sidewall and backing-up screw are two all just also, groove and screw are evenly distributed, and both can guarantee the intensity of screw bolt and nut, can make backing-up screw comparatively reasonable to the location of nut again.
Description of drawings:
The schematic representation that Fig. 1 matches for the utility model screw bolt and nut;
Fig. 2 is the structural representation of nut of the present utility model;
Fig. 3 is the plan view of bolt of the present utility model;
Fig. 4 is the structural representation of backing-up screw of the present utility model;
Shown in the figure 1, bolt; 2, nut; 3, screw rod; 4, backing-up screw; 5, groove; 6, screw.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, four jiaos of screw bolt devices of the utility model, the nut 2 that it comprises bolt 1 and matches with it.
Described bolt 1 is four angle head bolts, and promptly the head of bolt 1 is the square cylinder, and described nut 2 is a tetragonal nut, and the main body of nut 2 also is the square cylinder, and the screw rod 3 of described bolt 1 is provided with Full Thread FT; Described screw rod 3 is provided with two along screw rod 3 axially extended grooves 5, the sidewall of described nut 2 is provided with two screws 6, this screw 6 is to connect with the center hole of nut 2, being provided with in the described screw 6 matches with groove 5 merges backing-up screw 4 with nut 2 location, and backing-up screw 4 screws its latter end of back with screw 6 and is against in the groove 5.
For ease of manufacturing, described groove 5 is the end face of axial through bolt 1 afterbody preferably, and the length of groove 5 can be according to the use condition setting of reality.As preferred version, the groove 5 on the described screw rod 3 is two, and described two grooves 5 are symmetrical arranged along the axis of screw rod 3, and described screw 6 also is two and is symmetrical arranged along the axis of nut 2 that described backing-up screw 4 is two.
