Description

Spring bicycle rear seat for children

The utility model relates to the child seat on a kind of bicycle, specifically is a kind of elasticity bicycle children back seat.

At present, child seat on the bicycle is modal to be the rattan chair formula, this product is generally fixing with the rope binding, fixing is poor, and the patent that also many request for products arranged is as Chinese patent CN2088072U, CN2082701U or the like, they pay attention to fixed form, convenient disassembly, the multifunction of child seat, obviously, these products all ignored as child seat the basic function that should have, that is exactly the anti-seismic performance of seat.The product that has has also been considered shock resistance, but generally is by adding short spring under its saddle with shockproof, because the elasticity of short spring is limited, effect is all undesirable; The shockproof structure of the product that also has is complicated, the productive costs height.And because children's bone and internal organ are grown prematurity still, the regular vibrations of jolting on bicycle are unfavorable for its healthy development, and may cause some diseases.

The object of the present invention is to provide a kind of excellent spring, shockproof properties bicycle children back seat strong, simple in structure.

Technical scheme of the present invention is two supports of present rebasing welding, and pressure spring is contained on the support, utilizes the pressure spring excellent elasticity, reaches shockproof effect, and provides pedal frame to use for step.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model.

Fig. 2 is that the scheme drawing that frame (8) are stepped on frame (7) and a left side is stepped on H pipe (13), the right side.

Fig. 3 is a lateral plan of the present utility model.

Fig. 4 is the front view of seat cushion (1) and support (11), (12).

Fig. 5 is that the utility model is installed in the scheme drawing on the bicycle.

Structure of the present utility model as shown in Figure 1, it is to be stepped on by the seat cushion (1) that is welded with support (11) and support (12), H pipe (13), the right side that frame (7), a left side are stepped on frame (8), adapter plate (15), bolt (18) and pressure spring (5), (6), (9), (10) constitute, wherein the crossbeam (14) of H pipe (13) is a right angle bending iron or " ⊥ " shape bending iron, and crossbeam (14) is fixed on H pipe (13) on the rear bicycle frame (19) by bolt (18) with adapter plate (15); H pipe (13) cover is support (11), (12) then, on support (11), pressure spring (5), (9) are installed in the two ends up and down of H pipe (13) respectively, on support (12), pressure spring (6), (10) also are installed in the two ends up and down of H pipe (13) respectively, and the right side is stepped on frame (7) and a left side and stepped on frame (8) and weld the right left both sides that are associated in H pipe (13) respectively; Can fix the backrest (2) of a vehicle seat on the seat cushion (1), have two on the backrest (2) in order to the fixedly ring of safety belt (3), (3 '); Pressure spring (9), (10) are fixing by latch (17), (16) of the tail end of support (11), (12) respectively.During installation, unload bottom plate (15) and bolt (18) earlier, to install pressure spring (5), (6), (9), (10) support (11) on the seat cushion (1), (12) be inserted in the support neutral gear of mounting (19) afterwards, be positioned at position placed in the middle, crossbeam (14) until H pipe (13) is located, utilize the adapter plate (15) and the bolt (18) of broad then, two sides up and down from back mounting (19), after corresponding with a circular hole on the crossbeam (14), with bolt (18) and inner nut, with H pipe (13), thereby whole children's back seat is fixed on the back mounting (19).Wherein there is a circular hole at the middle part of adapter plate (15), passes for bolt (18), again with an inner nut and fastening the getting final product of bolt (18).Because the structure all similar of the back mounting of all bicycles is used so the utility model is fit to general bicycle.

Because H pipe (13) is to be socketed on support (11), (12), be fixed on again on the back mounting (19), seat cushion (1) then can be up and down in the flexible scope of pressure spring (5), (6), (9), (10).When bicycle is given a shock, by pressure spring (5), (6), (9), (10) better elastic, eliminates vibrations, thereby reach the purpose of protection children's health children's influence by bus.

The utlity model has excellent spring, reliable, the advantage such as anti-seismic performance strong, install firmly, project organization is simple, production cost is low, be conducive to child protection and avoid the adverse effect that the bicycle vibrations cause.
