Abstract
The utility model discloses a fastening pin. The fastening pin comprises a pin head and a pin body, wherein the pin head and the pin body are connected into a whole, strip-shaped grooves are formed in the outer wall of the pin body, sliding grooves which are used for sliding and parallel to the pin body are formed in the inner walls of the strip-shaped grooves, inclined strip blocks which are matched with the strip-shaped grooves are arranged on the strip-shaped grooves respectively, the inclined strip blocks can relatively slide in the sliding grooves, and the face, opposite to the contact face between each inclined strip block and the bottom face of one of the strip-shaped grooves, of each inclined strip block inclines upward and outward from the inserting end. The fastening pin has the advantages of being strong in fastening performance and not prone to loosening.
Description
Technical field
The utility model relates to handling instrument, relates in particular to a kind of fixed pin.
Background technique
Fixed pin is simple in structure, and mounting or dismounting are convenient, very wide in the various middle application that are fixedly connected.Fixed pin is mainly used to fix two relative positions between part, also for connected component, and can transmit certain load.The kind of fixed pin is various, normally conical, that tip or pinnacle are arranged timber, metal tingle, and fixed pin easily occurs connecting unstable, easily loosening when connecting.
The model utility content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of loosening fixed pin that is difficult for.
For achieving the above object, the utility model provides following technological scheme: a kind of fixed pin, comprise plunger and pin body, described plunger is connected with the pin body, and described pin body outer wall is provided with strip groove, and described groove inwall both sides are provided with the chute for sliding, be provided with the slanted bar piece in described strip groove, described slanted bar piece is outward-dipping by insertion end to the other end, and described slanted bar piece and strip groove are suitable, and the slanted bar piece is stuck in the chute of strip groove side.
By adopting technique scheme, when fixed pin is fixedly connected on certain position, by the pin body is carried out to latch, can be knocked and be fixed plunger, also can be by pin body outer wall, being provided with strip groove, and at the interior chute that is provided with, by in strip groove, be provided with can relative sliding the slanted bar piece, the face tilted by the slanted bar piece, can be according to the fastening situation of the latch between fixed pin and parts, select different slanted bar pieces and carry out closely, make fixed pin reach one and be not easy loosening effect.
The utility model further is set to: described plunger port is fixed with elastic membrane.
By adopting technique scheme, elastic membrane is set, can reduce a kind of wearing and tearing when plunger is beaten, well protected plunger.
The utility model further is set to: described plunger, pin body and slanted bar piece are provided with zinc coat.
By adopting technique scheme, due to zinc, in dry air, be difficult for changing, 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 fixed pin, fixed pin consists of stainless steel, zinc and fixed pin matrix form microcell, make the fixed pin matrix become negative electrode and be protected.Therefore zinc coat can be used for anti-oxidationly and anticorrosion, plays the effect of protecting fixed pin.
The utility model further is set to: described slanted bar piece, chute and strip groove are provided with wearing layer.
By adopting technique scheme, wearing layer is set to be comprised of abrasive rubber, abrasive rubber has good wear resistance and tightness, the slanted bar piece is relative sliding in the chute of strip groove, easily produce wearing and tearing, abrasive rubber can play wear-resisting effect, and the degree of wear that has slowed down fixed pin has well extended working life.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is the utility model embodiment spring bolt.
Fig. 2 is the utility model embodiment spring bolt plan view.
Reference character in figure: 1, slanted bar piece; 2, strip groove; 3, chute; 4, pin body, 5, plunger.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.
A kind of fixed pin, comprise plunger and pin body 4, described plunger is connected with pin body 4, it is characterized in that: described pin body 4 outer walls are provided with strip groove 2, described groove inwall both sides are provided with the chute 3 for sliding, and in described strip groove 2, are provided with slanted bar piece 1, and described slanted bar piece 1 is outward-dipping by insertion end to the other end, described slanted bar piece 1 is suitable with strip groove 2, and slanted bar piece 1 is stuck in strip groove 2 side chutes 3.
By adopting technique scheme, when fixed pin is fixedly connected on certain position, by pin body 4 is carried out to latch, can be knocked and be fixed plunger 5, also can be by pin body 4 outer walls, being provided with strip groove 2, and at the interior chute 3 that is provided with, by in strip groove 2, be provided with can relative sliding slanted bar piece 1, the face tilted by slanted bar piece 1, can be according to the fastening situation of the latch between fixed pin and parts, select different slanted bar piece 1 and carry out closely, make fixed pin reach one and be not easy loosening effect.
Described plunger 5 ports are fixed with elastic membrane.
By adopting technique scheme, elastic membrane is set, can reduce a kind of wearing and tearing when plunger 5 is beaten, well protected plunger 5.
Described plunger 5, pin body 4 and slanted bar piece 1 are provided with zinc coat.
By adopting technique scheme, due to zinc, in dry air, be difficult for changing, 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 fixed pin, fixed pin consists of stainless steel, zinc and fixed pin matrix form microcell, make the fixed pin matrix become negative electrode and be protected.Therefore zinc coat can be used for anti-oxidationly and anticorrosion, plays the effect of protecting fixed pin.
Described slanted bar piece 1, chute 3 and strip groove 2 are provided with wearing layer.
By adopting technique scheme, wearing layer is set to be comprised of abrasive rubber, abrasive rubber has good wear resistance and tightness, slanted bar piece 1 is at the interior relative sliding of chute 3 of strip groove 2, easily produce wearing and tearing, abrasive rubber can play wear-resisting effect, and the degree of wear that has slowed down fixed pin has well extended working life.
The utlity model has following advantage: by when fixed pin connects object, with the slanted bar piece, play fixation, guarantee that fixed pin is difficult for 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.
