Abstract
The utility model relates to machine parts, in particular to a novel bolt used for fastening. The novel bolt is characterized by being a fastener composed of a head, a gasket and a screw. The head is a circular cone, and a line-shaped open groove or a cross open groove or a hexagonal open groove is formed in the top end of the head, and is used for screwing or loosening the bolt; the gasket is fixedly arranged on the connecting portion of the head and the screw; the screw is a cylinder with external threads; the fastener is integrally formed by the head, the gasket and the screw. The clamping and fixing effect of the novel bolt is more ideal through special circular cone design and the principle of the bolt.
Description
Technical field
The utility model relates to mechanical parts, is specifically related to be applied to a kind of Novel bolt of fastening effect.
Background technique
At present, existing connection door is the bolt of usefulness, needs arrange at door porose, and bolt passes the hole on the door, and it is fixing to be screwed in bolt at the another side of door with nut; There is defective in such connection: an end of bolt is provided with nut, need when mounted first bolt to be shaked out from the hole on the connecting rod one end end face, allow the nut of bolt stay in the connecting rod, and then be installed on the door, but also need to pad be installed at bolt, this mode is very time-consuming, and trouble has reduced the speed of installing.
The model utility content
For the deficiency that prior art exists, it is a kind of rational in infrastructure that the utility model provides, simple structure, and efficiency of assembling is higher, more firmly a kind of Novel bolt.
For achieving the above object, this practicality provides one one kinds of Novel bolts, and the utility model adopts following technological scheme: a kind of Novel bolt; It is characterized in that by a class fastening piece that head (1), pad (2) and screw rod (3) form; Described head (1) is the cone of circle, and the top is provided with word fluting, or the cross fluting, or interior hexagonal fluting, for bolt being tightened or being become flexible; Described pad (2) is fixedly arranged on head (1) and screw rod (3) joint; Described screw rod (3) is with externally threaded cylindrical body; The fastening piece that described head (1), pad (2) and screw rod (3) are formed as one.
Advantage of the present utility model: 1, the utility model utilizes unique circular cone design, the principle of fitted bolt again, thus make the effect that is fixedly clamped better.
2, the utility model is simple in structure, is skillfully constructed, and design science is reasonable, and simultaneously its processing and fabricating is simpler, and cost is low, operate lightly, and the efficiency of assembling height connects more firm.
Description of drawings
Fig. 1 is the utility model structural representation;
Symbol description among the figure: head 1, pad 2, screw rod 3.
Embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, a kind of Novel bolt; It is characterized in that by a class fastening piece that head (1), pad (2) and screw rod (3) form; Described head (1) is the cone of circle, and the top is provided with word fluting, or the cross fluting, or interior hexagonal fluting, for bolt being tightened or being become flexible; Described pad (2) is fixedly arranged on head (1) and screw rod (3) joint; Described screw rod (3) is with externally threaded cylindrical body; The fastening piece that described head (1), pad (2) and screw rod (3) are formed as one.The utility model has changed existing door knob installation method: need first bolt to be shaked out from the hole on the connecting rod one end end face during existing the installation, allow the nut of bolt stay in the connecting rod, and then be installed on the door, but also need to pad be installed at bolt.Only need be connected in bolt of the present utility model on the connecting rod of door knob, and on another handle link position, tighten just in the head (1) of Novel bolt with screw and effectively couple together.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
