Abstract
The utility model discloses a technique solution is to provide an anti -drop fastening bolt who has following structure: including bolt, nut and anti -drop block. Wherein anti -drop block inside sets up the spring, and one end is sealed, and the opening symmetry sets up two fixed buckle bobbles. Wherein the thread end department of threaded rod 1 is equipped with a L type buckle groove, and the diameter of buckle bobble slightly is lighter than the width of L type draw -in groove, and the buckle bobble can freely slide in buckle groove. When the construction bolt, can twist into screw rod along buckle groove with the anti -drop block, its inside spring can seal the section with the block at the end part of the screw rod and exert elasticity, can make the buckle bobble block tightly in the turn crotch, prevents that effectively the nut comes off. When dismounting bolt, can screw out anti -drop block along buckle groove, this process such as need not weld at the process, and consequently the construction installation is very convenient. The utility model discloses can drop by the very effectual nut that prevents.
Description
Technical field
This utility model relate to a kind of bayonet type slip-off preventing fastening bolt, belongs to connection loose-preventing fastening technical field.
Background technology
Look for the slip-off preventing fastening bolt that state commonly uses to be stop punched-type structure or welding type at present, install, dismantle extremely inconvenient. When using common nut and nut screw connection locking parts, in order to prevent loosening between bolts and nuts, between nut and the parts being locked, generally to pad spring washer, the elastic force relying on spring washer increases the frictional force between the screw thread that bolts and nuts match, and then prevent loosening between bolts and nuts, although this method can play effect locking between bolts and nuts, but in actual application, by padding upper spring washer, to carry out locking effect less desirable. The phenomenon that can often loosen between bolts and nuts, causes potential safety hazard.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of when using with common nut screw connection, can effectively prevent the buckle-type fastening bolt that nut loosening comes off.
Technical solution of the present utility model is to provide a kind of slip-off preventing fastening bolt with following structure: include bolt (1), nut (2) and slip-off preventing block (4). Wherein slip-off preventing block (4) is internal arranges spring (5), and one end is closed, and opening part is symmetrical arranged two fixing buckle beads (6). Wherein the end of thread place of threaded rod (1) is provided with a L-type snap-fit grooves (3), and the diameter of buckle bead (6) is slightly less than the width of L-type draw-in groove (3), and buckle bead (6) can in snap-fit grooves (3) slidably.
The end of snap-fit grooves described in the utility model (3) is with a turnover crotch (7), and it is inner that buckle bead (6) can be stuck in turnover crotch (7).
Accompanying drawing explanation
Fig. 1 is buckle-type slip-off preventing fastening bolt axonometric chart. Fig. 2 is slip-off preventing block axonometric chart. Fig. 3 is slip-off preventing block front view.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, this utility model slip-off preventing is fastened bolt to be described further:
As shown in Figure 1, Figure 2 and Figure 3, in this embodiment, this utility model slip-off preventing fastening bolt includes bolt (l), nut (2) and slip-off preventing block (4) composition.Wherein screw rod (1) end arranges L-type snap-fit grooves. Wherein slip-off preventing block (4) arranges two fixing buckle beads (6), and buckle bead (6) can slide along snap-fit grooves (3). The diameter of buckle bead (6) is slightly less than the width of snap-fit grooves (3), and the diameter of slip-off preventing block (4) is slightly larger than the diameter of screw rod (1).
When installing bolt, slip-off preventing block (4) can be screwed into screw rod along snap-fit grooves (3), its contained spring (5) can apply elastic force in screw rod end and block closed section, it is possible to makes buckle bead (6) be stuck in tightly in turnover crotch (7), it is prevented that can effectively come off by nut (2).
When demounting bolt, can slip-off preventing block (4) being screwed out along snap-fit grooves (3), this process such as need not weld at operation, the therefore construction and installation extremely convenient.
Above-described enforcement is only that preferred implementation of the present utility model is described; not scope of the present utility model is defined; under the premise designing spirit without departing from this utility model. various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims are determined.
