Abstract
The utility model discloses a position-limiting bolt which is characterized in that a bolt head, a screw rod and a flange disc are in an integrated structure; the connecting part of the screw rod and the flange is provided with a chamfer I; the lower end of the screw rod is provided with a thread and a cone; the screw rod is also sheathed by a washer; the internal diameter of the washer is slightly less than the external diameter of the thread; the washer can slide up and down on the screw rod, but the washer does not fall off the thread; and the internal wall of the washer is also provided with a chamfer II which is matched with the chamfer I. The position-limiting bolt is simpler and more convenient to assemble, thus greatly improving the assembling efficiency.
Description
Technical field
The utility model relates to a kind of threaded connector, specifically is a kind of caging bolt.
Background technique
Present caging bolt on the market, constitute by bolt head and screw rod, bolt head and screw rod contact position are provided with flange plate, bolt head, screw rod and flange plate are an integral body, when installing and using since flange plate be directly and part contacted, therefore, flange plate is worn after long-term the use easily, and working life is short, has increased maintenance cost.
Summary of the invention
It is not easy to wear that the purpose of this utility model provides a kind of not only flange plate, and assembling is simple, convenient, the caging bolt that efficiency of assembling is high.
To achieve these goals, the utility model bolt head, screw rod and flange plate are integral structure, the joint of described screw rod and flange plate is provided with chamfering I, be provided with screw thread and cone in the lower end of screw rod, also be with a packing ring on screw rod, the internal diameter of described packing ring is slightly less than the external diameter of screw thread, and packing ring can slide up and down on screw rod, but packing ring can not come off from screw thread, and the packing ring inwall also is provided with the chamfering II that matches with chamfering I.
By above setting, the utility model guarantees having packing ring under the nonabradable situation of flange plate, because the packing ring internal diameter that is with on the screw rod is slightly less than the diameter of screw rod lower thread, therefore, described packing ring can become the integral body of a complete use with the utility model under the stopping of screw thread, make assembling of the present utility model become more simple and convenience, thereby improve efficiency of assembling of the present utility model greatly.
As a kind of improvement of the present utility model, described screw rod can be established chamfering I with being connected of flange plate; Described packing ring inwall is provided with the chamfering II that matches with chamfering I.The setting of chamfering I has increased the intensity of the utility model screw rod and flange plate joint greatly.
