The specific embodiment
Referring to figs. 1 through Fig. 4, press first embodiment of the sleeve 10 that sign shows for tool of the present invention, described sleeve 10 has one for ratchet wrench hand-driven first end 101, and one for second end 102 that drives working substance.First end 101 of described sleeve 10 is provided with a connecting hole 11, and described connecting hole 11 has a depth D (with reference to Fig. 1 or Figure 19), and described sleeve 10 is provided with more than one marked area 12 in the axial range of outer surface with respect to described connecting hole 11 depth D of first end 101.Present embodiment is to be respectively equipped with a marked area 12 in first end, 101 2 sides to be best expression, and described first end 101 also can only have a side to be provided with a marked area 12 certainly.The people who has common knowledge in this area also can change into it, forms the marked area 12 more than two at first end, 101 places of described sleeve 10, as three marked areas 12 or four variations such as marked area 12.
In the present embodiment, described sleeve 10 is American sleeve 10 structures, and its outward appearance is that first end 101 and second end 102 are the same diameter size, and does not have the formation shoulder.The connecting hole 11 of described sleeve 10 is to be made as quadrangle poroid (being square hole).Certainly, it is poroid or dodecagon is poroid that described connecting hole 11 also can be made as hexagon.
The marked area 12 of described sleeve 10 has a bottom 121 and and is convexly equipped with sign mark 122 in described bottom 121, and described bottom 121 is the bottom surface of marked area 12, and the height of described sign mark 122 end faces does not exceed the outer surface of sleeve 10.In addition, 121 both sides, described bottom are formed with first border 124 of a longitudinal extension respectively, have one first joint face 125 between the outer surface of described first border 124 and sleeve 10 first ends 101.Also promptly, the bottom surface of described bottom 121 and described first joint face 125 intersections form described first border 124.Again, described bottom 121 also is formed with two second borders 126 that are connected to 124 ends, described 2 first borders, has one second joint face 127 between the outer surface of described second border 126 and sleeve 10 first ends 101.Also promptly, the bottom surface of described bottom 121 and described second joint face 127 intersections form described second border 126.More described border the 124, the 126th around the bottom 121 that forms sealing, the bottom 121 of each marked area 12 is not linked to each other and independent the existence each other, and the sign mark 122 that is convexly equipped with in described bottom 121 is not connected yet with described border 124,126.Therefore, marked area 12 of the present invention is as if suffering bump or being in (as high temperature, liquid etc.) or the permanent identity that all still can possess good structure and height down of using under the bad working environment, and the user can be provided more convenient and easy observing effect, improve the life-span and the durability of marked area 12.
The outer surface of described sleeve 10 has a peripheral radius, and the center of circle of described peripheral radius is positioned at the axial location of sleeve 10, and the bottom 121 of described marked area 12 has a bottom surface radius, and the center of circle of described bottom surface radius is to rely on sleeve 10 inboards.The bottom surface radius of 12 bottoms 121, described marked area and the peripheral radius angle of sleeve 10 outer surfaces are zero degree.Also be that formed plane of radius, described bottom surface and the formed plane included angle of described peripheral radius are zero degree.
The inverse of a radius of a circle is exactly round curvature.Therefore, the inverse of aforementioned sleeve 10 peripheral radius is first curvature c1, and outer surface and sleeve 10 cross sections that this first curvature c1 is described sleeve 10 first ends 101 intersect the curve that cuts that is cut.And the inverse of the bottom surface radius of aforementioned described bottom 121 is torsion c2, and this torsion c2 is 121 surfaces, bottom and the crossing section curve that is cut of sleeve 10 cross sections of described marked area 12.
Because described sleeve 10 is when molded described marked area 12, the outer surface of sleeve 10 can be pushed inwardly, that is to say, described marked area 12 is one-body molded in described sleeve 10 first ends 101 all sides via punching press, design through the applicant, relational expression under adopting, the structure of the marked area 12 in the time of can making extruding is the most smooth processor, so first curvature c1 and torsion c2 have following relational expression:
c1≥1.5c2
Also promptly, first curvature c1 perhaps, we can say that also first curvature c1 is not less than 15 times of torsion c2 more than or equal to 15 times of torsion c2.Therefore, when the center of circle of described bottom surface radius relies on sleeve 10 when inboard, the bottom 121 of described marked area 12 establishes that to be convex arc planar.That is to say that coexist the mutually bending direction of first curvature c1 of the bending direction of torsion c2 is so the bottom 121 of described marked area 12 is convex shape, as Fig. 4.
And described sign mark 122 is formed with a top 123, described top 123 has an end face radius, described end face radius equals the bottom surface radius, and the inverse of the end face radius of described sign mark 122 is the 3rd curvature c3, that is to say, the end face of described sign mark 122 has identical curvature with the surface of 12 bottoms 121, described marked area, and relational expression is as follows:
c3＝c2
Therefore, it is planar that the convex arc that is identical with 12 bottoms 121, described marked area is established at the top 123 of described sign mark 122.
According to aforementioned relational expression, also can derive second embodiment as Fig. 5 to Fig. 8.In the present embodiment, the bottom surface radius convergence of described marked area 13 is in infinity, so the center of circle of bottom surface radius at infinity, the bottom 131 of described marked area 13 will be driven closely plane, and the top 133 of described sign mark 132 is established and is and 13 bottoms, 131 identical the driving closely plane of described marked area.That is to say that torsion c2 is zero, so the bottom 131 of described marked area 13 is plane, as Fig. 8.
According to aforementioned relational expression, also can derive the 3rd embodiment as Fig. 9 to Figure 12.In the present embodiment, the bottom surface radius rightabout of the bottom surface radius of described marked area 14 and first embodiment, when the center of circle of described bottom surface radius is when relying on sleeve 10 outsides, the bottom 141 of described marked area 14 establishes that to be concave arc planar, and that the concave arc that is identical with 14 bottoms 141, described marked area is established at the top 143 of described sign mark 142 is planar.That is to say that the bending direction of torsion c2 is on the contrary at the bending direction of first curvature c1, so the bottom 141 of described marked area 14 is invaginated type, as Figure 12.
With reference to Figure 13 to Figure 15, press the 4th embodiment of the sleeve 20 that sign shows for tool of the present invention.Present embodiment is identical with first embodiment haply, its difference place is that the sleeve 20 of present embodiment is to be embodied as European sleeve 20 structures, its outward appearance is that first end 201 is the different-diameter size with described second end 202, and be formed with shoulder between the two, all the other structures first embodiment that then coexists mutually is so no longer given unnecessary details at this.
With reference to Figure 16 to Figure 20, press the 5th embodiment of the sleeve 20 that sign shows for tool of the present invention.Present embodiment the 4th embodiment that coexist mutually haply, its difference place is that the bottom surface radius of 23 bottoms 231, described marked area and the peripheral radius angle of sleeve 20 outer surfaces are 90 degree.Also be that formed plane of radius, described bottom surface and the formed plane included angle of described peripheral radius are 90 degree.Therefore, when the center of circle of described bottom surface radius relies on sleeve 20 when inboard, the bottom 231 of described marked area 23 establishes that to be convex arc planar.
And the inverse of a radius of a circle is exactly round curvature.Therefore, the inverse of aforementioned sleeve 20 peripheral radius is first curvature c1, and outer surface and sleeve 20 cross sections that this first curvature c1 is described sleeve 20 first ends 201 intersect the curve that cuts that is cut.And the inverse of the bottom surface radius of aforementioned described bottom 231 is torsion c2, and this torsion c2 is 231 surfaces, bottom and the crossing section curve that is cut in sleeve 20 longitudinal sections of described marked area 23.That is to say that coexist the mutually bending direction of first curvature c1 of the bending direction of torsion c2 is so the bottom 231 of described marked area 23 is convex shape, as Figure 19.
With reference to Figure 21 to Figure 25, be the 6th embodiment of the present invention, present embodiment is identical with the 5th embodiment haply, and its difference place is that the center of circle of described bottom surface radius is when relying on sleeve 20 outsides, and the bottom 241 of described marked area 24 establishes that to be concave arc planar.That is to say that the bending direction of torsion c2 is on the contrary at the bending direction of first curvature c1, so the bottom 241 of described marked area 24 is invaginated type, as Figure 24.
With reference to Figure 26 and Figure 27, be the 7th embodiment of the present invention, present embodiment is identical with second embodiment haply, and its difference is in the bottom surface of described bottom 151 and described sleeve 10 first ends 101 outer surface intersections and forms described first border 154.Again, described bottom 151 also is formed with two second borders 156 that are connected to 154 ends, described 2 first borders, has one second joint face 157 between the outer surface of described second border 156 and sleeve 10 first ends 101.Also promptly, the bottom surface of described bottom 151 and described second joint face 157 intersections form described second border 156.More described border the 154, the 156th around the bottom 151 that forms sealing, the bottom 151 of each marked area 15 is not linked to each other and independent the existence each other, and the sign mark 152 that is convexly equipped with in described bottom 151 is not connected yet with described border 154,156.Certain described bottom 151 also can be embodied as the convex shape or the invaginated type of previous embodiment.Therefore, marked area 15 of the present invention is as if suffering bump or being in (as high temperature, liquid etc.) or the permanent identity that all still can possess good structure and height down of using under the bad working environment, and the user can be provided more convenient and easy observing effect, improve the life-span and the durability of marked area 15.
