Abstract
The utility model discloses a fastening type bolt, including spiral shell head, screw rod, spring, gasket, the spiral shell head be the hexagonal drive head of regular hexagon shape, the lower extreme is connected the screw rod, the screw rod be the cylinder shape, the surface is provided with the screw, the spring be located spiral shell head lower extreme welding together, spring the central axis department pass through the screw rod, the spring other end be provided with the gasket, the gasket be rubber gasket, the central axis department is provided with a round hole, can pass through just the screw rod, the gasket along with the spring flexible and remove, wherein, during the use, the rubber gasket direct contact who connects on the spring suppresses on the object, more fastens. In this way, the utility model discloses novel structure sets up in the spiral shell overheadly through the spring with even there being rubber gasket, pass through rubber and object contact during the use, increase frictional force between the two to fastening nature during the reinforcing bolt fastening, easy operation, convenient and practical.
Description
Technical field
The utility model relates to fixed component field, particularly relates to a kind of fastening type bolt.
Background technique
Bolt is the one of mechanical parts, the cylindrical threaded fastening piece of adapted nut, by head and a screw rod class fastening piece dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole, but, common bolt is all that metal spiral shell head directly contacts with object when using, can not damage object, and frictional force is between the two less, not firmly.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of fastening type bolt, can increase the frictional force between object and bolt, thus strengthens tightness when bolt is fixed, simple to operate, convenient and practical.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of fastening type bolt, it is characterized in that, comprising: spiral shell head, screw rod, spring, pad, described spiral shell head is the hexagonal spiral shell head of regular hexagon shape, the screw rod described in lower end connects; Described screw rod is cylindrical shape, and surface is provided with screw thread; Described spring is positioned at described spiral shell head lower end and welds together, and described spring center axis place is by described screw rod, and the described spring the other end is provided with described pad; Described pad is rubber sheet gasket, and central axis place is provided with a circular hole, can just by described screw rod, and pad moves along with described telescopic spring; Wherein, during use, the rubber sheet gasket that spring connects directly contacts to be suppressed on object, more fastening.
In the utility model preferred embodiment, described spiral shell head and screw rod form by round steel processing and fabricating.
In the utility model preferred embodiment, described spring is made up of spring steel.
In the utility model preferred embodiment, described pad is made up of rubber, centered by have the ring structure of a circular hole, circular hole is just by described screw rod.
The beneficial effects of the utility model are: the utility model novel structure, by the spring being connected with rubber sheet gasket is arranged at Luo Toushang, by rubber and object contact during use, increase frictional force between the two, thus the tightness strengthened when bolt is fixed, simple to operate, convenient and practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of fastening type bolt one of the utility model preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, spiral shell head; 2, screw rod; 3, spring; 4, pad.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of fastening type bolt, it is characterized in that, comprising: spiral shell head 1, screw rod 2, spring 3, pad 4, described spiral shell head 1 is the hexagonal spiral shell head of regular hexagon shape, the screw rod 2 described in lower end connects; Described screw rod 2 is cylindrical shape, and surface is provided with screw thread; Described spring 3 is positioned at described spiral shell head 1 lower end and welds together, and described spring 3 central axis place is by described screw rod 2, and described spring 3 the other end is provided with described pad 4; Described pad 4 is rubber sheet gasket, and central axis place is provided with a circular hole, can just by described screw rod 2, and pad 4 stretches along with described spring 3 and moves; Wherein, during use, the rubber sheet gasket 4 that spring 3 connects directly contact is suppressed on object, more fastening.
Be different from prior art.
In another embodiment, described spiral shell head 1 forms by round steel processing and fabricating with screw rod 2, and material enriches, and fabricating cost is low, and processing technique is ripe; Described spring 3 is made up of spring steel, and elasticity is large, durable; Described pad 4 is made up of rubber, centered by have the ring structure of a circular hole, circular hole is just by described screw rod 2, and quality of rubber materials is partially soft, and sense of touch is comfortable, and frictional force is large, and tightness is good.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
