Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, the attachment face 110 that this structure improved bearing pin comprises main body 100 and is opened in main body 100, attachment face 110 offers the through hole 120 running through main body 100, latch can be installed in through hole 120 and one end of latch can through through hole 120 protruding, the first positioning part 200 and the second positioning part 300 has been extended to form respectively at the two ends of main body 100, thread section 210 and guiding groove 310 is respectively equipped with away from main body 100 sides in the first positioning part 200 and the second positioning part, the first mounting groove 220 and the second mounting groove 320 is respectively arranged with near main body 100 sides in the first positioning part 200 and the second positioning part 300, and described first mounting groove is connected with threaded end, described second mounting groove 320 communicates with guiding groove 310.
The shape of aforementioned body 100 is cylindric, the shape of attachment face 110 is square and is arranged at the outer surface of main body 100, thus the radial length of attachment face 110 is equal with axial length, and the axial length of attachment face 110 is equal with the axial length of main body 100, but the radial length of attachment face 110 is less than the diameter of main body 100, make the area of attachment face 110 be less than the maximum secting area of main body 100, avoid due to the overlapping with the sectional area of main body 100 diameter very few of attachment face 110 and cause the installation of main body 100 unstable.
Preferably, the two ends of aforementioned body 100 are formed with the first positioning part 200 and the second positioning part 300 respectively, first positioning part 200 is provided with thread section 210, the axial length of thread section 210 is equal with the axial length of the first positioning part 200, second positioning part 300 offers guiding groove 310, preferably, the quantity of guiding groove 310 is one, but guiding groove 310 is not limited to 1, it can be 2 even many, and guiding groove 310 is arranged on the second positioning part 300 outer surface in the shape of a spiral, in the process of installing, bearing pin is for connecting the first workpiece and second workpiece, above-mentioned first positioning part 200 is threadedly connected on the first workpiece, the setting be threaded ensure that the stability that the first positioning part 200 is connected with the first workpiece, avoid bearing pin and the first workpiece occurs to depart from and affects the generation of the normal work phenomenon of bearing pin between the two, second positioning part 300 is arranged with second workpiece, make bearing pin the first workpiece and second workpiece in the process of work can be resisted against in the both ends of the surface up and down of main body 100, avoid the first workpiece and second workpiece swings when being installed in main body 100 and affects the normal work of bearing pin.
Further, the diameter of above-mentioned through hole 120 is equal with the axial length of attachment face 110, when the first workpiece and second workpiece are installed on bearing pin, through hole 120 can be equipped with latch, the diameter of latch is less than or equal to the diameter of through hole 120, the setting of latch is equivalent to the extension of main body 100, first workpiece and second workpiece are all resisted against on latch, avoid diameter due to main body 100 too small and cause the first workpiece and second workpiece install unstable and affect the generation of the normal work phenomenon of bearing pin.
Above-mentioned guiding groove 310 is arranged on the outer surface of the second positioning part 300 in the shape of a spiral, in guiding groove 310 and on thread section 210, oiling agent is provided with in the process of work, the setting of oiling agent ensure that lubricity good between assembly department and workpiece, avoid due to the second positioning part 300 and second workpiece and the generation of phenomenon to block between the first positioning part 200 and the first workpiece time, affect the normal work of the first workpiece and second workpiece.
Preferably, the axial length of above-mentioned first mounting groove 220 and the second mounting groove 320 is all less than the axial length of attachment face 110, on the first mounting groove 220 and the second mounting groove 320, the sidewall of close main body 100 one end is all in arc-shaped, first mounting groove 220 communicates with thread section 210, second mounting groove 320 is connected with guiding groove 310, thus the oiling agent in thread section 210 and guiding groove 310 can flow in the first mounting groove 220 and the second mounting groove 320 along screw thread and manipulation respectively, first mounting groove 220 and arranging of the second mounting groove 320 can be carried out recycling to oiling agent thus avoid the waste of oiling agent, reduce the user cost of bearing pin.
Chamfering 400 is provided with away from main body 100 one end in the first positioning part 200 and the second positioning part 300, the setting of chamfering 400 eliminates the sharp edge of two assembly departments, avoid sharp edge causes the phenomenon of scuffing generation to operator, simultaneously chamfering 400 setting party the installation of bearing pin, decrease the installation time of bearing pin, improve installation efficiency.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
