Description

Children's counter-base

Technical field

The utility model relates to a kind of children's counter-base, specifically a kind of for public bicycle or other inclined tube bicycles, the automobile-used preposition children's counter-base of electrical salf-walking, belongs to daily necessities field.

Background technology

Public bicycle is because of its environmental protection, convenient and swift, in a lot of cities, carries out using at home, also by the common people, accepted gradually, but generally public bicycle is cant beam and does not establish back seat, can only a people ride seat, if just cannot use with children; Or other inclined tube bicycles, Electrical Bicycle; more commonly child seat is arranged on to back seat; bicyclist is difficult to observe and look after the children that are sitting in below in the process of riding; even if child seat is provided with safety precautions; particularly centre-of gravity shift, swaying when turning round, also have potential safety hazard.

For solving problems, there is multi-form forward type child seat in currently available technology, fixed often, can not folding and unfolding, and structure is more complicated, and having destroyed design cant beam is the design original intention that facilitates rider upper and lower.

Summary of the invention

For the problems referred to above, the utility model provides a kind of children's counter-base, is folding structure, during use, decontrols, and the used time does not pack up, and does not destroy oblique beam structure, is applicable to all bicycle or Electrical Bicycles with oblique beam structure.

To achieve these goals, the utility model comprises link span, crossbeam, seat, strut bar, base and stretcher, and handlebar main shaft is fixed in link span one end, and the other end is connected by bearing pin with crossbeam; Crossbeam is trench structure, can rotate around link span bearing pin, and the other end connects strut bar by bearing pin; Seat plate is provided with hooking structure, and is provided with lock bolt, can slide and lock along crossbeam, and seat is provided with the safety strap of little backrest and length adjustable, and its little backrest is provided with aperture, and seat is covered with elastic shock attenuation material; Strut bar is also trench structure, and its width is less than crotch width in crossbeam grooved, can turn folding and be hidden in crossbeam along 90 ° of scopes of crossbeam bearing pin, and its other end is provided with anti-skidding footmuff; Base is fixed on bicycle cant beam, is provided with lattice block section, and surface is covered with skid resistant course, strut bar can be positioned in lattice block section, prevents strut bar withdrawal; Stretcher is arranged on cant beam certain position, is provided with hinge, can rotate along 90 ° of scopes of hinge axis.

Preferably link span and cant beam, handlebar main shaft are made of one structure.

Compared with prior art, these children counter-base is forward type structure, and above children are sitting in, bicyclist not only can observe directly, and can perceive with both arms, the both legs driven, can look after easily children; So be applicable to have bicycle or the Electrical Bicycle of oblique beam structure; Be folding structure, during use, decontrol and prop up carrying children, after the used time do not pack up, be still oblique beam structure, facilitate rider upper and lower.

Sequence number and title in figure: 1 link span, 2 crossbeams, 3 seats, 4 strut bars, 5 bases, 6 stretchers, 7 hooking structures, 8 lock bolts, 9 little backrests, 10 safety strap, 11 latching systems, 12 length adjustment devices, 13 antiskid glue sleeves, 14 handlebar main shafts, 15 cant beams.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, these children counter-base comprises link span 1, crossbeam 2, seat 3, strut bar 4, base 5 and stretcher 6.

As shown in Figure 2 and Figure 3, handlebar main shaft 14 is fixed in link span 1 one end, and the other end is connected by bearing pin with crossbeam 2.

Crossbeam 2 is trench structures, can rotate around link span 1 bearing pin, and the other end connects strut bar 4 by bearing pin.

As shown in Fig. 4, Fig. 5, Fig. 6, seat 3 base plates are provided with hooking structure 7, and hanging sleeve, on crossbeam 2, can make seat 3 slide along crossbeam 2 front and back, and hooking structure 7 is provided with lock bolt 8 above, seat 3 can be locked on crossbeam 2; Seat 3 rear portions are provided with little backrest 9.

Strut bar 4 is also trench structure, and its width is less than crotch width in crossbeam 2 grooveds, can turn folding and be hidden in crossbeam 2 along 90 ° of scopes of crossbeam 2 bearing pin.

Base 5 is fixed on bicycle cant beam 15, is provided with lattice block section, and after strut bar 4 can being strutted, by it, the one end with antiskid glue sleeve 13 is positioned in lattice block section, can prevent strut bar 4 improper withdrawal in use.

Stretcher 6 is arranged on certain position on cant beam 15 by hinge, can rotate along 90 ° of scopes of hinge axis.

Link span 1 can be fastenedly connected with bolted mode and handlebar main shaft, also can directly be welded on handlebar main shaft 14 and be made of one structure with cant beam 15, handlebar main shaft 14.Because the latter's scheme is more firm, there will not be link span 1 because firmly not connecting and produce axial rotation, make whole counter-base produce position skew, so preferred the latter's scheme, link span 1 is directly welded on handlebar main shaft 14 and is made of one structure with cant beam 15, handlebar main shaft 14.

Further, children are sitting on counter-base uncomfortablely when avoiding riding on the road surface of jolting, and seat 3 surfaces are covered with elastic shock attenuation material.
