Detailed description of the invention
Please first consult Fig. 1 and Fig. 2, bogie car hand cradle 10 of the present utility model includes pedestal 20, vertical tube 30, and one handle 40.
Pedestal 20 is mainly used for sheathedly being fixed on a vertical tube of front fork 12 and having bearing and leaning portion 21 and an axle portion 22, the bottom in axle portion 22 is connected to bearing and leaning portion 21, and the external diameter in axle portion 22 is less than the external diameter of bearing and leaning portion 21, in addition, the top in axle portion 22 has two relative fixed orifices 25.
One end clipping of vertical tube 30 in a driver 14, the other end of vertical tube 30 has a socket part 31, the socket part 31 of vertical tube 30 is sheathed on the axle portion 22 of pedestal 20 by an adjustment packing ring 50, to avoid producing structural wearing and tearing between the two, adjustment packing ring 50 is incorporated into the root edge of the socket part 31 of vertical tube 30 with screw-in version, and be sheathed on the rear bearing and leaning portion 21 being simultaneously resisted against pedestal 20 in axle portion 22 of pedestal 20, vertical tube 30 is rotated between a use location P1 (as shown in Figure 1) and a reception position P2 (as shown in Figure 8) by adjustment packing ring 50 opposite base 20.In addition, as shown in Figure 2, vertical tube 30 has two the first relative location indentations 32 and two the second relative location indentations 33, this 2 first location indentations 32 and this 2 second location indentations 33 be located at respectively socket part 31 apical margin and in being staggered centered by the axial direction of socket part 31.
Handle 40 has a pulling part 41 extension arm 42 relative with two, and each extension arm 42 goes out from the apical margin horizontal expansion of pulling part 41, and the end of each extension arm 42 has the pivot hole 44 that a positioning convex portion 43 and runs through positioning convex portion 43.Handle 40 is hubbed at the top in the axle portion 22 of pedestal 20 by two pivots 28, pivot 28 passes the pivot hole 44 of the extension arm 42 of handle 40 and is fixed on screw-in version in the fixed orifice 25 in the axle portion 22 of pedestal 20, make handle 40 can between a latched position P3 (as shown in Fig. 1 and Fig. 8) with a releasing position P4 (as shown in FIG. 6 and 7) relative vertical tube about 30 pivotable.In addition, handle 40 also has a second gear stop 45, as shown in Figure 2, second gear stop 45 be located at pulling part 41 apical margin and between this two extension arm 42.
In order to avoid handle 40 is surprisingly pulled, as shown in Figures 2 to 5, bogie car hand cradle 10 of the present utility model also provides a security component 60, security component 60 has upper cover 61 and an elastic component 62, upper cover 61 covers the top in axle portion 22 and has two relative long slot bores 63, each long slot bore 63 wear by pivot 28, upper cover 61 can be moved along the diametrically axle portion 22 in axle portion 22, in addition, the outside face of upper cover 61 has a first gear stop 64; Again as shown in Figure 4, be connected to the end wall of spring groove 26 in the spring groove 26 that one end of elastic component 62 is contained in the axle portion 22 of pedestal, the other end of elastic component 62 is connected to the inside face of upper cover 61, in order to impose the strength of ejection outward to upper cover 61.
When to use driver 14 time, first vertical tube 30 is turned to use location P1, then the pulling part 41 of handle 40 is pressed down, in the process pressing down handle 40, the second gear stop 45 of handle 40 can extrude the first gear stop 64 of upper cover 61, upper cover 61 is moved towards the direction away from handle 40, mutually stagger once between the first gear stop 64 and the second gear stop 45 of handle 40 of upper cover 61, handle 40 can be switched to latched position P3 as shown in Figure 1 smoothly, now the positioning convex portion 43 of handle 40 can be connected in the first location indentations 32 of vertical tube 30, in order to vertical tube 30 is positioned at use location P1, in addition, the upper cover 61 of pedestal 20 understands by the response force of elastic component 62 involution original position, at this time formed between first gear stop 64 meeting of upper cover 61 and the second gear stop 45 of handle 40 and interfere, to guarantee that handle 40 can not surprisingly be pulled.
On the other hand, when to receive driver 14 time, first promote upper cover 61, make mutually to stagger (as shown in Figure 5) between the first gear stop 64 of upper cover 61 and the second gear stop 45 of handle 40, then handle 40 is up pulled to releasing position P4 as shown in Figure 6 again, after handle 40 is positioned at releasing position P4, the positioning convex portion 43 of handle 40 can depart from the first location indentations 32 of vertical tube 30, at this time first remove the thrust to upper cover 61, make upper cover 61 by the response force of elastic component 62 involution original position, then again vertical tube 30 is turned to reception position P2 as shown in Figure 7, handle 40 is pressed down again after vertical tube 30 is positioned at reception position P2, in the process pressing down handle 40, the second gear stop 45 of handle 40 can extrude the first gear stop 64 of upper cover 61 again, upper cover 61 is moved towards the direction away from handle 40, mutually stagger once between the first gear stop 64 and the second gear stop 45 of handle 40 of base upper cover 61, handle 40 can be switched to latched position P3 as shown in Figure 8 smoothly, now the positioning convex portion 43 of handle 40 can be connected in the second location indentations 33 of vertical tube 30, in order to vertical tube 30 is positioned at reception position P2, and, again interference can be formed between first gear stop 64 meeting of upper cover 61 and the second gear stop 45 of handle 40, to guarantee that handle 40 can not be increased the safety in use by unexpected pulling.
In sum, bogie car hand cradle 10 of the present utility model has coordinated vertical tube 30 in the location of use location P1 and reception position P2 by vertical tube 30 between first, second location indentations 32,33 and positioning convex portion 43 of handle 40, with known technology by contrast, the utility model has more simple structure design really, operate also comparatively easy, manufacturing cost can reduce naturally effectively, and then reaches the purpose of this utility model.
