Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 3, the wheel assembly of a kind of doll carriage described in the present embodiment, arm 3 after including two that are connected by rear cross-tube 31, and two trailing wheels 4; After described two, arm 3 bottom is fixedly connected with two trailing wheel mount pads 41, and described rear cross-tube is fixedly connected between two trailing wheel mount pads; Described trailing wheel mount pad includes rear the pipe jointing part 411 be connected with rear arm and rear cross-tube, and the trailing wheel connecting portion 412 be connected with trailing wheel; Described trailing wheel connecting portion forms braking vane installation portion 413, described trailing wheel 4 center is connected with rear wheel quick-disassembling axle 401, described rear wheel quick-disassembling axle level is inserted in described trailing wheel connecting portion, the position that trailing wheel connecting portion differs from rear wheel quick-disassembling axle is connected with a braking vane axle 415 parallel with rear wheel quick-disassembling axle, braking vane axle is rotatably connected to braking vane, and described rear wheel quick-disassembling axle is through described braking vane; Torsion spring is connected with between described braking vane and trailing wheel connecting portion.Described torsion spring makes braking vane not offseting with rear wheel quick-disassembling axle by during external force, or keeps less friction force with rear wheel quick-disassembling axle, ensures that trailing wheel can rotate.
Described braking vane comprises and is arranged on main brake plate 43 on two trailing wheel mount pads and auxiliary brake plate 44 respectively, and main brake plate forms brake pedal; Connected by braking rope 45 between described main brake plate and auxiliary brake plate; Be arranged with brake rope sling in the middle part of described braking rope, below described trailing wheel mount pad, form brake rope sling fixed part 414; The end face of described trailing wheel connecting portion is also provided with a rear wheel quick-disassembling locking plate 46 coordinated with rear wheel quick-disassembling axle, the end face of trailing wheel connecting portion installation rear wheel quick-disassembling locking plate is also connected with the capping 42 that coordinates fixing rear wheel quick-disassembling locking plate.Described rear wheel quick-disassembling lock plate structure principle is identical with front-wheel quick detach locking plate, is beneficial to the fast assembling-disassembling of trailing wheel.Described braking vane is arranged on trailing wheel mount pad, and structure simply and do not occupy redundant space, makes doll carriage terminal with compact integral structure.Tramp with one's feet when stepping on main brake plate and drive the action simultaneously of auxiliary brake plate by braking rope, main brake plate and auxiliary brake plate produce friction force to the rear wheel quick-disassembling axle surface of two trailing wheels simultaneously and make rear service brake.Described braking vane can adopt solid rubber to make.
Described rear wheel quick-disassembling locking plate one end is exposed below trailing wheel mount pad, is connected between the other end with trailing wheel mount pad by spring.Described rear wheel quick-disassembling axle forms the positioning groove of annular, described rear wheel quick-disassembling locking plate has and coordinates locking hole clipping with positioning groove.
When installing trailing wheel, as long as the mounting hole that rear wheel quick-disassembling axle is aimed on trailing wheel mount pad is inserted, rear wheel quick-disassembling locking plate automatically and circular groove clamp and fix.When needing brake, the lower main brake plate that tramps with one's feet can drive main brake plate and auxiliary brake plate to brake the rear wheel quick-disassembling axle of two trailing wheels simultaneously simultaneously, and braking effect is good.
