Description
Multi-functional tricycle baby carriage of the present utility model belongs to a kind of carriage for children, particularly can be suitable for children, contrary foot-operated, adult's push-and-pull, child's study is walked and multifunctional child that can loading.
Toy tricycle at present commonly used is made up of vehicle frame, handlebar, foot-operated, vehicle seat and three wheels, is that the toy tricycle of riding usefulness is ridden in a kind of confession.
The purpose of this utility model was to provide a kind of both can suitablely for children, contrary having ridden to ride usefulness, again can be for adult's push-and-pull, also can take a step to walk and multi-functional tricycle baby carriage that can loading, to remedy the existing deficiency of toy tricycle special purpose at present commonly used for child study.
Multi-functional tricycle baby carriage of the present utility model is made up of handlebar (7), car fork (3), vehicle seat (9), front and rear wheel with wide track (1) (15), foot-operated (2), vehicle frame (17), trolley pole (10), brake lever (6), treadmill direction reverser.
The treadmill direction reverser is mounted on the axle of front-wheel (1).This treadmill direction reverser is the internal tooth ratchet (25) that has a pair of forward and reverse ratchet (34) (35) on the same wheel shaft, forward and reverse ratchet (34) (35) symmetry is installed in the inside groove of pawl-bearing cover (23), one annual spring (24) is arranged on the central channel of forward and reverse ratchet (34) (35), restrict forward and reverse ratchet (34) (35).There is reversing cover (33) outside of forward and reverse ratchet (34) (35), pawl-bearing cover (23).
On the side of pawl-bearing cover (23) circular groove is arranged, the straight pin (22) with passing mandrel sleeve (28) is fixed on the mandrel sleeve (28) pawl-bearing cover (23).
There is a commutation supporting sleeve (27) on the right side of pawl-bearing cover (23) and reversing cover (33), there is a dovetail spring (26) at commutation step place, supporting sleeve (27) end, and the other end and the unlubricated bearing (29) of commutation supporting sleeve (27) link.
The outstanding end of pawl-bearing cover (23), reversing cover (33), commutation supporting sleeve (27), in internal tooth ratchet (25) chamber, have three symmetrical keys to match with the keyway of wheel hub (32) inner chamber on the endoporus of internal tooth ratchet (25) end, internal tooth ratchet (25) is fixed on the wheel hub (32) with screw (31).
Mandrel sleeve (28) other end is provided with a commutation cap (20) that interior hexagonal axial keyway is arranged, between commutation cap (20) and the pawl-bearing cover (23) a hexagonal axis bearing sleeve (21) is arranged, the outer-hexagonal face of hexagonal axis bearing sleeve (21) matches with the interior hexagonal square hole of wheel hub (32), and outside the outstanding wheel hub (32).
Foot-driven lever (18) in mandrel sleeve (28) and insertion mandrel sleeve (28) the two ends endoporus is with cylinder locating dowel pin (19) location.
Vehicle frame (17) is the double-pipe type curve shape of being made by a metal tube, and its front end is flat semicircle, fixes with vertical shaft sleeve pipe (4) welding.The top of vehicle frame (17) rear end is drilled with equidistant three to four positioning apertures, and vehicle seat (9) is fixed on the vehicle frame (17) with vehicle seat bolt (8).
The trolley pole (10) of single pole is equipped with in rear end in vehicle frame (17).Trolley pole (10) is divided into two joints, and wherein the upper end of a joint is associated with cart handle (11), and another joint links with the inserted link of go-cart pole socket (13).Between trolley pole (10) two joints and between trolley pole (10) and the go-cart pole socket (13), connect, and all use spring pin (12) location to peg graft.Go-cart pole socket (13) and back axle (14) are fixed on the below, rear end of vehicle frame (17) with fly-headed bolt (16).
Brake lever (6) is housed between two trailing wheels (15).This brake lever (6) be "
" Metallic rod of shape, and passing that slightly larger in diameter is in two holes of Metallic rod on back axle (14) side, the bracket arm (5) that has brake crank is welded on the brake lever (6).
Now several functions of the present utility model are described below:
(see figure 3) when the direct motion treadmill, its forward ratchet (34) stretches out from the opening part (C) of reversing cover (33), withstands internal tooth ratchet (25) tooth root left part, under the effect of treadmill power, front-wheel (1) is moved in the direction of the clock; If when moulding treadmill, its reversing cover (33) is along with backwards rotation, because dovetail spring (26) has restricted the rotation of reversing cover (33), forward ratchet (34) is pressed in the inside groove, and be symmetrical in the opening part (D) of the reverse ratchet (35) of forward ratchet (34) from reversing cover (33), under the pressure of annual spring (24), stretch out, withstand the opposite side of internal tooth ratchet (25) tooth root, make front-wheel (1) press anticlockwise motion.
When treadmill not, reversing cover (33) is in " neutral " position, its forward and reverse ratchet (34) (35) all is pressed in the inside groove of pawl-bearing cover (23), front-wheel (1) is free rotary state, if during with trolley pole (10) push-and-pull perambulator, just can not rotate with front-wheel (1) foot-driven lever (18) and foot-operated (2).
When the uncomfortable use treadmill of children direction reverser, as long as after commutation cap (20) changed 180 ° direction and install, just become the treadmill form of the perambulator commonly used that foot-driven lever (18) freely rotates with front-wheel (1).
With trolley pole (10) go-cart the time, be not subjected to the restriction of treadmill direction reverser, this is because the sliding bearing of front-wheel (1) is to be supported by the hexagonal supporting sleeve (21) and internal tooth ratchet (5) the bearing at end cover (30) that are installed on the mandrel sleeve (28).Not during treadmill, its front-wheel (1) is free rotary state, and foot-driven lever (18) does not rotate with front-wheel (1), when if go-cart is walked rapidly or is turned, can a little firmly depress cart handle (11), make front-wheel (1) built on stilts a little, utilize two trailing wheels (15) to travel, go-cart adult for differing heights, when using trolley pole (10), because the several positioning apertures on the inserted link of go-cart pole socket (13), available spring pin (12) changes the length of trolley pole (10), thus the level height of scalable cart handle (11).
The braking that perambulator slides relies on brake lever (6) to finish, and promptly spurs bracket arm (5), makes brake lever (6) form leverage, utilizes brake lever (6) and the friction force that two trailing wheels (15) contact, and reaches the purpose of braking brake.
This perambulator is used for one year old child and learns walking and walk very safe.Fly-headed bolt (16) can be unclamped during use, lay down go-cart pole socket (13).In order not make child stroller too fast, can with bracket arm (5) with bolts such as bungee or cords in the handle aperture of vehicle seat (9), carry out the drag of trace (or appropriateness), the child is under adult's treatment, hold handlebar (7) or holding up vehicle seat (9), pushing away or along with toy tricycle study walking is walked.
In addition, if mobile vehicle seat bolt (8) can change the front and back position of vehicle seat (9), do not make the same year children use to adapt to.
The vehicle frame (17) and the front and rear wheel with wide track (1) (15) of the double-pipe type curve shape of making by a metal tube that provides, be not only and try to achieve the moulded grace of perambulator, also can make perambulator sturdy and durable, use this perambulator also to be convenient to go shopping or transport packed the dress to be no more than 50 kilograms article with case.
Multi-functional tricycle baby carriage of the present utility model is compared with toy tricycle at present commonly used, can be when having treadmill along contrary commutation, drag, and does not rotate with front-wheel (1) foot-operated (2) during push-and-pull vehicle, and vehicle seat (9) such as can move forward and backward at characteristics.Both having can be for children along the contrary foot-operated usefulness of riding, again can be for adult's push-and-pull, also can for the child learn that walking is walked and can loading etc. multiple use, modern design, exotic shape, sturdy and durable are that a kind of desirable children use car.
