Abstract
The invention discloses a dual-washer type hexagonal head bolt. The dual-washer type hexagonal head bolt comprises a bolt head and a bolt rod. The bolt rod is provided with the threaded end and the smooth end. The outer surface of the threaded end is provided with screw threads. A conical elastic washer is disposed in the position, close to the bolt head, of the smooth end. A flat washer is disposed in the position, close to the threaded end, of the smooth end. The conical elastic washer comprises an opening and a conical body. The included angle between the outer end face of the opening and the outer inclined surface of the conical body is alpha which is in the angle range of four degrees to six degrees. In this way, the whole bolt can be protected, the bolt is prevented from being damaged by too large force, meanwhile, looseness after connection of the bolt and a nut can be prevented as well, and the fastening property of the bolt is improved.
Description
Technical field
The present invention relates to a kind of bolt, particularly to a kind of double washer type hexagon-headed bolts.
Background technology
Along with improving constantly of science and technology; bolt is extensively favored by all trades and professions as one of accessory requisite in securing member; its demand is greatly improved; the quality of bolt weighed mostly by bolt in the market with its intensity; bolt all uses a packing ring to carry out protective effect during actually used between bolt and caught workpiece, generally based on plain washer, and this type of way; not only the protection to bolt and caught workpiece is less, and anti-loosening ability is poor.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of double washer type hexagon-headed bolt, it is possible to protection bolt is overall, prevents bolt to be damaged owing to strength is excessive, can also prevent screw bolt and nut from occurring after connecting to loosen simultaneously, improve the tightness of bolt.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of double washer type hexagon-headed bolt to include: screw head and screw rod, described screw rod is provided with the end of thread and smooth end, the outer surface of the described end of thread offers screw thread, on described smooth end, at described screw head, it is provided with taper elastic washer, on described smooth end, at the described end of thread, is provided with plain washer;
Described taper elastic washer includes: opening and bullet, and it is 4 ~ 6 ° that the angle between outer face and the outer inclined-plane of described bullet of described opening is designated as the angular range of α, α.
In a preferred embodiment of the present invention, described screw head is turret head flange face screw head.
In a preferred embodiment of the present invention, the material of described taper elastic washer is spring steel.
In a preferred embodiment of the present invention, the maximum gauge of described taper elastic washer and described plain washer, less than the length of described smooth end, prevents packing ring damaged screw, thus reduces the tightness of bolt.
The invention has the beneficial effects as follows:
(1), the present invention uses the mode adding plain washer, it is possible to defective work piece and the surface of bolt when preventing bolt and nut from tightening;
(2), the present invention uses the mode adding taper elastic washer, it is possible to occur when preventing caught workpiece from beating or shake to loosen;
(3), use the mode combining plain washer and taper elastic washer, both can guarantee that caught workpiece and bolt self were not damaged by, moreover it is possible to the fastening effect of entirety is greatly improved.
Accompanying drawing explanation
Fig. 1 is present invention structural representation in a preferred embodiment;
Fig. 2 is the structural representation of the taper elastic washer shown in Fig. 1;
In accompanying drawing, the labelling of each parts is as follows: 1, screw head, and 2, screw rod, 3, plain washer, 4, taper elastic washer, 21, the end of thread, 22, smooth end, 23, screw thread, 41, opening, 42, bullet.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of double washer type hexagon-headed bolt, including: screw head 1 and screw rod 2, described screw rod is provided with the end of thread 21 and smooth end 22, the outer surface of the described end of thread 21 offers screw thread 23, on described smooth end 22, at described screw head 1, it is provided with taper elastic washer 4, on described smooth end 22, at the described end of thread 21, is provided with plain washer 3;
As shown in Figure 2, described taper elastic washer 4 includes: opening 41 and bullet 42, angle between outer face and the outer inclined-plane of described bullet 42 of described opening 41 is designated as α, the angular range of α is 4 ~ 6 °, for controlling the bending amplitude of taper elastic washer 4, the amplitude preventing taper elastic washer 4 from bending is excessive, and causes taper elastic washer 4 to damage.
Wherein, described screw head 1 is turret head flange face screw head;The material of described taper elastic washer 4 is spring steel;The maximum gauge of described taper elastic washer 4 and described plain washer 3, less than the length of described smooth end 22, prevents packing ring damaged screw, thus reduces the tightness of bolt.
Further illustrate, present invention is disclosed a kind of double washer type hexagon-headed bolt, its main operation principle is: first inserted by screw rod 2 in the screwed hole of caught workpiece, the end of thread 21 at screw rod 2 uses nut to screw subsequently, after plain washer 3 contacts caught workpiece, taper elastic washer 4 being axially gradually driven plain along smooth end 22, after this taper elastic washer 4 is driven plain completely, caught workpiece is i.e. clamped completely by the double washer type hexagon-headed bolt of the present invention.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
