Abstract
The utility model discloses a limit bolt which is composed of a bolt head (1) and a screw rod (2); a flange plate (3) is arranged on the contact part of the bolt head (1) and the screw rod (2; the bolt head (1), the screw rod (2) and the flange plate (3) are integrated into a whole; the screw rod (2) comprises a polish rod (4) close to the flange plate (3), a thread structure in the middle part and a cone (5) at the bottom; a gasket (6) is nested on the polish rod (4); the inner diameter of the gasket (6) is slightly less than the large diameter of the middle thread structure of the screw rod(2); and the outer diameter of the gasket (6) is more than the outer diameter of the flange plate (3). The limit bolt has the advantages that: the flange plate is not easy to be abraded, the assemblyis simple and convenient, and the assembly efficiency is high.
Description
Technical field:
The utility model relates to a kind of threaded connector, specifically is a kind of caging bolt.
Background technique:
Disclose the utility model patent that a kind of name is called " a kind of caging bolt " on the China national intellectual property board web, this model utility is made of bolt head and screw rod; Described bolt head and screw rod contact position are provided with flange plate; Described bolt head, screw rod and flange plate are an integral body; Described screw rod is made up of three parts, is polished rod near bolt head and flange plate end, and the middle part is a worm structure, and the bottom is a cone.Though this model utility has guiding accurately owing to the screw rod bottom is provided with cone when mounted, is difficult for the characteristics of stripped thread, because flange plate is directly contacted with part, therefore, flange plate is being worn after long-term use easily.
The utility model patent that a kind of name is called " a kind of automobile assembling bolt " is also disclosed on the China national intellectual property board web, this model utility has increased a plain washer and a spacer ring again on the basis of above-mentioned model utility, plain washer and spacer ring the wearing and tearing that can effectively prevent flange plate are set, prolonged the working life of bolt.Yet, because plain washer and spacer ring all are to be screwed on the bolt by the internal thread on their endoporus, thereby make the assembling of this bolt comparatively bother, efficiency of assembling is lower.
The model utility content:
The technical problems to be solved in the utility model is provide a kind of not only flange plate not easy to wear more, and assembling to be simple, convenient, the caging bolt that efficiency of assembling is high.
Technical solution of the present utility model is, a kind of caging bolt with following structure is provided, and it is made of bolt head and screw rod; Described bolt head and screw rod contact position are provided with flange plate; Described bolt head, screw rod and flange plate are an integral body; Described screw rod comprises the polished rod near the flange plate place, the cone that is positioned at the worm structure at middle part and is positioned at the bottom; Be with a packing ring on the described polished rod; The internal diameter of described packing ring is slightly less than the Major Diam on the worm structure of screw rod middle part; The external diameter of packing ring is much larger than the external diameter of flange plate.
After adopting said structure, the utlity model has following advantage: compared with prior art, because the packing ring internal diameter that is with on the polished rod is slightly less than the Major Diam on the worm structure of screw rod middle part, therefore, described packing ring can become the integral body of a complete use with the utility model under the stopping of screw thread, in other words, the utility model is after production is finished, packing ring just becomes as a whole with the utility model, the user is when using the utility model, need not to be screwed into packing ring on the screw rod in the utility model more in addition, make assembling of the present utility model become more simple and convenience, thereby improve efficiency of assembling of the present utility model greatly.In addition, because the external diameter of packing ring is much larger than the external diameter of flange plate, in other words, the area that the utility model middle washer can contact with part increases greatly, and therefore, the utility model flange plate is not easy to wear more.
Description of drawings
Accompanying drawing is the structural representation of a kind of caging bolt of the utility model.
Shown in the figure 1, bolt head, 2, screw rod, 3, flange plate, 4, polished rod, 5, cone, 6, packing ring.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, in this specific embodiment, a kind of caging bolt of the utility model is made of bolt head 1 and screw rod 2; Described bolt head 1 is provided with flange plate 3 with screw rod 2 contact position; Described bolt head 1, screw rod 2 and flange plate 3 are an integral body; Described screw rod 2 comprises the polished rod 4 near flange plate 3 places, the cone 5 that is positioned at the worm structure at middle part and is positioned at the bottom; Be with a packing ring 6 on the described polished rod 4; The internal diameter of described packing ring 6 is slightly less than the Major Diam on the screw rod 5 middle part worm structures, and in other words, packing ring 6 can slide up and down on polished rod 4, but described packing ring 6 can not come off from the worm structure of polished rod 4; The external diameter of packing ring 6 is much larger than the external diameter of flange plate 3.
