Abstract
The utility model relates to a quadrangle semi-thread bolt device with washers, which comprises a bolt and a nut matching with the same. The bolt is a quadrangle head bolt with a washer, the nut is a quadrangle head nut with a washer, a screw rod of the bolt is provided with a threaded section and a non-threaded section, the threaded section is close to the tail end surface of the screw rod and provided with at least one groove extending along the screw rod axially, at least one screw hole is arranged on the side wall of the nut, locking screws matching with the grooves and used for positioning the nut are arranged in the screw holes, and after the bolt is screwed with the nut, the locking screws are screwed into the screw holes on the side wall of the nut and the tail ends of the screws are abutted in the grooves on the bolt in actual use. Therefore, the nut can not rotate up and down and can not be loosened or separated regardless of service occasions.
Description
Technical field:
The utility model relates to fastener areas, relates in particular to a kind of four jiaos of partial thread band pad 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 partial thread band pad 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 partial thread band pad bolt devices with following structure are provided, it comprises bolt and the nut that matches with it, described bolt is four angle head band pad bolts, described nut is four jiaos of band pad nuts, the screw rod of described bolt is made up of thread section that is provided with screw thread and polished rod section, and described thread section is near the tail end face of screw rod; Described thread section 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:
Thread section at four jiaos of common partial thread band pad bolts is provided with groove, and the sidewall of the band pad nut that matches with it is provided with screw, when reality is used, after screw bolt and nut screws, again backing-up screw is screwed in the screw of nut sidewall and the end of screw is against in the groove on the bolt.Like this, no matter be to use in the sort 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.

Fig. 2 is the plan structure schematic representation of nut of the present utility model;
Fig. 3 is the plan structure schematic representation 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; 3.1, thread section; 3.2, the polished rod section; 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 partial thread bands of the utility model pad bolt device, the nut 2 that it comprises bolt 1 and matches with it.
Described bolt 1 is four angle head band pad bolts, the head that is bolt 1 is the square cylinder, described nut 2 is four jiaos of band pad nuts, the main body that is nut 2 also is the square cylinder, the working surface of bolt 1 head and the working surface of nut 2 all have flat gasket, described flat gasket is an one respectively at bolt 1 and nut 2, and the screw rod 3 of described bolt 1 is made up of thread section 3.1 that is provided with screw thread and polished rod section 3.2, and described thread section 3.1 is near the tail end face of screw rod 3; Described thread section 3.1 is provided with two along screw rod 3 axially extended grooves 5, the sidewall of described nut 2 is provided with two screws 6, described screw 6 is to connect with the center hole of nut 2, and being provided with in the described screw 6 matches with groove 5 merges backing-up screw 4 with nut 2 location.
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.
