Abstract
The utility model relates to a kind of retaining pin, comprise pile body and pile top, described pile body and pile top are composite material, and described pile top periphery is evenly provided with hangnail, one end and the pile top periphery of described hangnail are fixed, and the other end of hangnail is inclined upwardly towards the direction away from pile top tip.This retaining pin, by arranging the tip direction hangnail contrary with pile top at pile top place, adds the join strength of pin stake and miscellaneous part, adds installation soundness and the safety in utilization of pin stake.
Description
Technical field
The utility model relates to a kind of retaining pin.
Background technique
Composite material is with a kind of material for matrix, and another kind of material is the material that reinforcement combines, and various material makes up for each other's deficiencies and learn from each other in performance, produces synergistic effect and makes the combination property of composite material be better than former constouctional material and meet various different demand.
Along with the requirement of commercial Application is more and more higher, composite material is lightweight because of it, and fastness is high, and etch-proof performance, the frequency of utilization in industrial product is also more and more higher; In pin stake goods, original is all adopt reinforced concrete construction or build with metal, the most of heavier-weight of this product, and be corroded than being easier to, not enough in order to overcome this, there is the stake of part pin to have employed composite material and make material as it, thus alleviate overall weight, and enhance corrosion resistance.Existing pin stake is all a stake not with any safety structure, and this pin stake is easy to oppositely to depart from because of producing loosening after by use a period of time, is also easy to by extracting artificially and causes loss.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of structure simple, and the retaining pin be not easily pulled out.
The utility model solves the technological scheme that its technical problem adopts: a kind of retaining pin, comprise pile body and pile top, described pile body and pile top are composite material, described pile top periphery is evenly provided with hangnail, one end and the pile top periphery of described hangnail are fixed, and the other end of hangnail is inclined upwardly towards the direction away from pile top tip.
In order to increase the anti-corrosion capability of hangnail, described cone hangnail is composite material.
In order to be fixed hangnail, described hangnail by composite layer and pile top affixed, hangnail is fixedly connected with pile top by the described affixed composite material manual pasting forming process of namely adopting.
Conveniently install, described pile body is provided with mounting hole or fitting key away from one end of pile top.
Described composite material adopts glass fiber reinforced plastic to make.
Described glass fiber reinforced plastic body material is the one in unsaturated resin, isophthalic resin, adjacent benzene resin, vinylite, epoxy resin, bisphenol A type resin, reactive resin, and reinforcing material is the one in glass fibre, carbon fiber, aramid fibre, blend fiber.
The beneficial effects of the utility model are, this retaining pin, by arranging the tip direction hangnail contrary with pile top at pile top place, adds the join strength of pin stake and miscellaneous part, add installation soundness and the safety in utilization of pin stake.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model retaining pin;
Fig. 2 is the structural representation of the another kind of mode of execution of the utility model retaining pin;
In figure: 1. pile body, 2. pile top, 3. hangnail.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of retaining pin, comprise pile body 1 and pile top 2, it is characterized in that, described pile body 1 and pile top 2 are composite material, described pile top 2 periphery is evenly provided with hangnail 3, and one end and pile top 2 periphery of described hangnail 3 are fixed, and the other end of hangnail 3 is inclined upwardly towards the direction away from pile top 2 tip.
In order to increase the anti-corrosion capability of hangnail 3, described hangnail 3 is composite material.
Hangnail 3 by composite layer and pile top 2 affixed, particularly, hangnail 3 is fixed in pile top 2 by composite material manual pasting forming process, thus pin stake and then can not can only be retreated before pile top 2 tip direction.Composite material manual pasting forming process is for stack fibre cloth successively, and in the process stacked, hand sticks with paste reisn base material simultaneously, is fixed in pile top 2 by hangnail 3.
Conveniently install, described pile body 1 is provided with cylindrical mounting hole 4 away from one end of pile top 2, also can be fitting key 5 as shown in Figure 2, for fixing pin stake.
Composite material described in the present embodiment adopts glass fiber reinforced plastic to make, glass fiber reinforced plastic body material can be the one in unsaturated resin, isophthalic resin, adjacent benzene resin, vinylite, epoxy resin, bisphenol A type resin, reactive resin, and reinforcing material can be the one in glass fibre, carbon fiber, aramid fibre, blend fiber.
Compared with prior art, this retaining pin, by arranging the tip direction hangnail contrary with pile top 23 at pile top 2 place, adds the join strength of pin stake and miscellaneous part, adds installation soundness and the safety in utilization of pin stake.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
