Abstract
The utility model discloses a pin. The pin comprises a pin body and cylinder parts which are integrated with the pin body, wherein the cylinder parts are distributed on the two ends of the pin body; the cylinder part on one end of the pin body is provided with a convex tip; the convex tip is horizontally wound on the periphery of the cylinder part and protrudes from the surface of the cylinder part; an inclined plane is arranged on the connection part of the cylinder part and the convex tip. According to the pin disclosed by the utility model, the convex tip protrudes from the surface of the cylinder part so that the pin has a fixing effect when being used for connecting an object and the pin is not loosened.
Description
Technical field
The utility model relates to handling instrument, relates in particular to a kind of pin.
Background technique
Pin configuration is simple, and mounting or dismounting are convenient, very wide in the various middle application that are fixedly connected.Pin is mainly used to fix two relative positions between part, also for connected component, and can transmit certain load.The kind of pin is various, and normally conical, that tip or pinnacle are arranged timber, metal tingle, be mainly peg or fasten, but inapplicable for some abnormally-structured hole pin commonly used, easily loosening.
The model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of loosening pin that is difficult for.
For achieving the above object, the utility model provides following technological scheme: a kind of pin, comprise pin body and the cylinder part be wholely set with the pin body, described cylinder part distributes at pin body two ends, on the cylinder part of described pin body one end, be provided with spur, described spur horizontal winding is located at cylinder part all around and outstanding cylinder part surface, and the joint of described cylinder part and spur is provided with inclined-plane.
By adopting technique scheme, pin is when connecting abnormally-structured hole, the structure in this pin configuration and hole, big or small suitable, due to the outstanding cylinder part of spur surface, if when pin occurred to become flexible, spur can prop up hole, prevents that pin from shifting out outside hole, play fixation, thereby guarantee that pin is not loosening.
The utility model further is set to: the joint of described pin body and cylinder part is provided with arc surface.
By adopting technique scheme, arc surface is easily processed compared to the right angle face, add and by chamfering to the pin body surface to cylinder part, get final product man-hour, and the utilization ratio of material is high, has also improved working efficiency.
The utility model further is set to: described this external surface of pin is provided with zinc coat.
By adopting technique scheme, due to zinc, be difficult for changing in dry air, and in malaria, surface can generate a kind of very fine and close zinc carbonate film, this film can effectively protect inside no longer to be corroded.And when certain reason makes the coating failure and while exposing not too large pin, pin consists of stainless steel, zinc and pin matrix form microcell, make the pin matrix become negative electrode and be protected.Therefore zinc coat can be used for anti-oxidationly and anticorrosion, plays the effect of protecting pin.
The utility model further is set to: described Several Thiourea Derivatives on Zinc Plate Surface is provided with wearing layer.
By adopting technique scheme, wearing layer is comprised of abrasive rubber, abrasive rubber has good wear resistance and tightness, pin with have certain wearing and tearing after hole contacts, time one is long, the degree of wearing and tearing will be more and more serious, and abrasive rubber can play wear-resisting effect, has slowed down the degree of wear of pin; Because pin is that stainless steel forms, surface is coated with zinc in addition, and the air-tightness of wearing layer can stop extraneous air, moisture etc. to corrode pin.
The utility model further is set to: the quantity of described cylinder part is 2, is provided with the flange be wholely set with cylinder part on the end face of cylinder part near pin body two ends.
By adopting technique scheme, cylinder part is smooth through flange processing rear surface is set, and there is no seamed edge, can not hurt the people in production, installation or using process; In addition, the setting of flange has aesthetic property.
The utlity model has following advantage: due to the outstanding cylinder part of spur surface, when pin connects object, play fixation, guarantee that pin is not loosening.
The accompanying drawing explanation
Fig. 1 is the sectional view of the utility model pin;
Fig. 2 is the local amplification view of pin shown in Figure 1;
Fig. 3 is that the A-A of pin shown in Figure 1 is to sectional view.
In figure: 1, pin body; 2, cylinder part; 3, spur; 4, inclined-plane; 5, arc surface; 6, flange.
Embodiment
Referring to figs. 1 through shown in Figure 3, the pin of the present embodiment, comprise pin body 1 and the cylinder part 2 be wholely set with pin body 1, described cylinder part 2 is distributed in pin body 1 two ends, on the cylinder part 2 of described pin body 1 one ends, be provided with spur 3, described spur 3 horizontal windings are located at cylinder part 2 all around and outstanding cylinder part 2 surfaces, and described cylinder part 2 is provided with inclined-plane 4 with the joint of spur 3.
By adopting technique scheme, pin is when connecting abnormally-structured hole, the structure in this pin configuration and hole, big or small suitable, due to spur 3 outstanding cylinder part 2 surfaces, if when pin occurred to become flexible, spur 3 can prop up hole, prevents that pin from shifting out outside hole, play fixation, thereby guarantee that pin is not loosening.
Described pin body 1 is provided with arc surface 5 with the joint of cylinder part 2.
By adopting technique scheme, arc surface 5 is easily processed compared to the right angle face, add and by the chamfering to cylinder part 2 to pin body 1 surface, get final product man-hour, and the utilization ratio of material is high, has also improved working efficiency.
Described pin body 1 outer surface is provided with zinc coat.
By adopting technique scheme, due to zinc, be difficult for changing in dry air, and in malaria, surface can generate a kind of very fine and close zinc carbonate film, this film can effectively protect inside no longer to be corroded.And when certain reason makes the zinc coat failure and while exposing not too large pin, pin consists of stainless steel, zinc and pin matrix form microcell, make the pin matrix become negative electrode and be protected.Therefore zinc coat can be used for anti-oxidationly and anticorrosion, plays the effect of protecting pin.
Described Several Thiourea Derivatives on Zinc Plate Surface is provided with wearing layer.
By adopting technique scheme, wearing layer is comprised of abrasive rubber, abrasive rubber has good wear resistance and tightness, pin with have certain wearing and tearing after hole contacts, time one is long, the degree of wearing and tearing will be more and more serious, and abrasive rubber can play wear-resisting effect, has slowed down the degree of wear of pin; Because pin is that stainless steel forms, surface is coated with zinc in addition, and the air-tightness of wearing layer can stop extraneous air, moisture etc. to corrode pin.
The quantity of described cylinder part 2 is 2, is provided with the flange 6 be wholely set with cylinder part 2 on the end face of cylinder part 2 near pin body 1 two ends.
By adopting technique scheme, cylinder part 2 is smooth through flange 6 processing rear surfaces are set, and there is no seamed edge, can not hurt the people in production, installation or using process; In addition, the setting of flange 6 has aesthetic property.
The utlity model has following advantage: due to spur 3 outstanding cylinder part 2 surfaces, when pin connects object, play fixation, guarantee that pin is not loosening.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
