The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Shown in Fig. 1-7, perambulator comprises handle pipe 1, pin pipe etc., and handle pipe 1 is the U type, and it comprises handshake part 11, and and each connecting pin pipe of lower end of handshake part integrated two side pipes 12,13, two side pipes of upper lateral.Establish a service plate 3 between two side pipes, 12,13 tops of handle pipe, service plate 3 forms the hole of placing article.The two ends of service plate 3 cooperate formation resetting structure, gear structure respectively with two side pipes 12,13 of handle pipe, concrete structure is described below respectively.
One side pipe, 12 fit structures of service plate 3 and handle pipe: an end of service plate 3 outwards convexes into an annular arrangement cylinder 31; These cylinder 31 inside also form another annular arrangement cylinder 32; The coaxial laying of two cylinders leaves spacing between the outer wall of the inwall of cylinder 31 and cylinder 32.The side pipe 12 of handle pipe is through screw 6 affixed service plate reset seat 5; Service plate reset seat 5 is roughly cylindrical; Its axial cross section is the mountain font, and cylinder 31 internal diameters of external diameter and service plate 3 are corresponding, and center protruding 51 is stretched into screw 6 and is fixedly linked with the side pipe 12 of handle pipe 1; This middle part protruding 51 is also cylindrical, and inner cylinder 32 internal diameters of its external diameter and service plate 3 match.When service plate reset seat 5 stretches into this end of service plate 3; The inwall free-running fit of the cylinder 31 of the outer wall of service plate reset seat 5 and service plate 3; The inner cylinder 32 inwall free-running fits of protruding 51 outer walls in the middle part of service plate reset seat 5 and service plate 3, thus both just can relatively rotate, and; Spacing all and between the body of service plate 3 is left in the outside cylinder end of service plate reset seat 5, the end of internal protrusion 51; 12 of the end of the cylinder 31 of service plate 3 and side pipes leave spacing, leave spacing between the end of the inner cylinder 32 of service plate 3 and the bottom of service plate reset seat 5, thus service plate 3 side travel relatively.And, be inserted in retracing spring 4 outside the inner cylinder 32 of middle part of service plate reset seat 5 protruding 51 and service plate 3, the two ends of retracing spring 4 peak at the bottom of service plate reset seat 5, the body of service plate 3 respectively.
Another side pipe 13 fit structures of service plate 3 and handle pipe 1: it is columniform male part 35 that this end of service plate 3 outwards convexes into outer wall, and the axis that form 36,37, two gear holes 36,37, two horizontal gear holes in this male part 35 are 90 degree.The interior middle part of this protuberance 35 also forms annular arrangement cylinder 38.This side pipe 1 is through screw 6 captive joint service plate gear seats 2; The outer wall of service plate gear seat 2 is cylindrical; The internal diameter of the male part 35 of its external diameter and service plate 3 is suitable; The middle part of service plate gear seat 2 forms projection 21, and screw 6 stretches into projection 21 and is fixedly linked with side pipe 13, and the internal diameter of the cylinder 38 of the external diameter of projection 21 and service plate 3 is suitable.Service plate gear seat 2 also forms a positioning block 22, and this locating piece 22 laterally protrudes from service plate gear seat 2, and suitable with the horizontal gear hole 36,37 of service plate 3.When service plate gear seat 2 inserts this end of service plate 3, the inwall free-running fit of the male part 35 of its outer wall and service plate 3, and the inwall free-running fit of the inner cylinder 38 of the outer wall of its inner projection 21 and service plate 3, thus just can relatively rotate between the two; And spacing all and between the body of service plate 3 is left in the locating piece 22 of service plate gear seat 2, projection 21 ends; The end and the side pipe 13 of the male part 35 of service plate 3 leave spacing; The gap is left in the bottom of the end of the inner cylinder 38 of service plate 3 and service plate gear seat 2, makes service plate 3 side travel relatively.Be under Fig. 6 state, this locating piece 22 inserts the gear hole 36 of service plate 3 and service plate 3 can't be rotated.If want lazy Susan 3, catch service plate 3 earlier, along laterally pushing service plate reset seat 5 one sides to, at this moment, retracing spring 4 is compressed with it, and the locating piece 22 of service plate gear seat 2 has just broken away from the gear hole 36 of service plate 3; The service plate 3 that overturns then unclamps after putting in place, and service plate 3 laterally toward moved back, inserts locating pieces 22 of service plate gear seats 2 in its gear hole 37 under the effect of retracing spring 4, and service plate 3 is locked.
More than preferred implementation of the present invention is specified; Those of ordinary skill in the art will be appreciated that; According to thought provided by the invention, the part that on concrete embodiment of the present invention and field of application, all can change, these changes also should be regarded as protection scope of the present invention.
