Abstract
The utility model discloses a clamping bolt, which comprises a bolt head and a bolt bar arranged on the lower part of the bolt head, wherein the bolt bar is provided with a threaded segment; and a clamping hole is formed in the tail part of the bolt bar. The clamping hole is formed in the tail part of the bolt bar, after the bolt and a nut are screwed tightly, a structural part such as an iron wire or a pin is inserted or nailed into the clamping hole, and the nut is blocked on the threaded segment of the bolt, so that the nut is effectively prevented from falling off due to vibration in a vibrating working condition, the fastening effect is improved, and the working service life of the bolt is prolonged.
Description
Technical field
The utility model relates to the screens bolt.
Background technique
The screw bolt and nut cooperating is used for the fastening two items that is easy to shake at most cases.In the environment of vibrations, nut is easy to be shaken gradually come off, and causes fastening failure and may cause a series of security incident.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of screens bolt, can prevent effectively that nut from coming off from bolt.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of screens bolt, comprise bolt head and the screw rod of being located at the bolt head bottom, and screw rod is provided with thread section, and the afterbody of described screw rod is provided with the screens hole.
As a kind of improvement, described screens hole is located at the rear portion of thread section on the screw rod.
As a kind of improvement, described screens hole is located on the polished rod at the rear of thread section on the screw rod, and the distance of described screens hole and thread section rear end is less than the height of nut.
As a kind of improvement, described screens hole is tapered blind hole.Cooperate the taper pin screens, be used for the nut of on-slip fitted bolt.
As a kind of improvement, described screens hole is manhole.
As a kind of improvement, described screens hole is square through hole.
The technical solution adopted in the utility model, its beneficial effect is: the afterbody at bolt arranges the screens hole, after screw bolt and nut screws, to insert iron wire in the screens hole or hammer into structural member such as pin, the nut retaining is leaned against on the thread section of bolt, prevent that effectively nut from being come off by vibrations, improved fastening effect and its operating life in the working environment of vibrations.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a kind of embodiment's of the utility model structural representation;
Fig. 2 is the another kind of embodiment's of the utility model structural representation.
Embodiment
Embodiment one
A kind of embodiment's of the utility model structural representation as shown in Figure 1, a kind of screens bolt comprises bolt head 1 and is located at the screw rod 2 of bolt head bottom that screw rod is provided with thread section 3, the afterbody of described screw rod is provided with screens hole 4.
In the present embodiment, the rear portion of described screens hole thread section on screw rod.
Described screens hole is manhole.When screw rod penetrates the attachment hole for the treatment of fixing article, nut is screwed in thread section, in the screens hole, insert iron wire thereafter or other can protrude from the structural member of screw thread, be used for the retaining of nut, effectively avoid nut to come off from bolt.
Embodiment two
As shown in Figure 2, be that with embodiment's difference the thread section on the described screw rod is located at the middle part of screw rod, the rear portion of screw rod is provided with polished rod 5, and described screens hole is located on the polished rod, and the distance of described screens hole and thread section rear end is less than the height of nut.
In addition to the implementation, described screens hole also can be tapered blind hole, and the auxiliary taper pin of mixing, and is used for the nut retaining, the screens hole can also be square through hole, accompanies later effectively limit screw cap such as auxiliary structural member such as iron wire as long as can satisfy to adorn in the screens hole.
Except above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
