Description

Detachable portable multifunctional baby carriage

Technical Field

The invention relates to a baby carriage, in particular to a detachable portable multifunctional baby carriage.

Background

The baby carriage commonly seen in the market is of an integral fixed structure, is not foldable and storable, and is inconvenient to carry. While collapsible strollers are also now commercially available, they are nevertheless deficient in portability. Especially when parents take children to travel outside, because the emotion of the baby is variable, the baby is fragile, the baby carriage must be carried, and although the baby carriage is convenient and portable to a certain extent, the baby carriage does not have a good containing function, and can only be carried on the hands, and if people have large flow or other conditions, other articles are carried on the body, so that the baby carriage is inconvenient. A multifunctional detachable portable stroller with publication number CN201510047859.2, which is multifunctional for dining tables, is not focused on the main functions of the stroller itself, but has many detachable components, is inconvenient to detach or assemble, and is time-consuming. Secondly, the Sail bag formed by the cushion is contained with the following defects: possibly, the canvas bag is too small, and some things cannot be put down; because the components are all hard metal or plastic, friction damage and the like are easily formed on human bodies when the components are arranged in a canvas bag; secondly, the canvas bag is not easy to carry, especially in the case of infants.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the detachable portable baby carriage which is simpler in structure, more convenient to carry and capable of achieving the function of containing articles.

The aim of the invention can be achieved by the following technical scheme:

a detachable portable baby carriage comprises a structural member, a seat, a backrest and wheels,

Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present invention.

Examples

A detachable portable baby carriage has a structure shown in fig. 1-2, and comprises a structural member, a seat, a backrest and wheels.

The structural parts mainly comprise a pair of telescopic lifting rods 4, a telescopic rear wheel shaft 14, a telescopic front wheel shaft 15, a pair of supporting rods 7 for supporting a seat 6 and the telescopic rear wheel shaft 14 and the telescopic front wheel shaft 15, a pair of connecting rods 11 and a pair of bending supporting rods 10 for connecting and supporting the telescopic rear wheel shaft 14 and the telescopic

front wheel shaft

15, 4 buckles 2 for telescopic rods and telescopic shafts for telescopic and 8 sleeves for connecting and positioning, (3), (5) and (13): the structure of the sleeve is shown in fig. 4, wherein the 4 small hole ends are provided with a second sleeve 5 with a large round end without threads, the 2 small hole ends and the large round end are provided with a third sleeve 13 with threads, and the 2 small hole ends and the large round end are provided with a first sleeve 3 without threads. The above components are symmetrically distributed except for the retractable rear axle 14 and the retractable front axle 15.

The telescopic push rod 4 is connected with the backrest 1 through a pair of first sleeves 3: the large round side of the sleeve is fixed with the backrest with a threaded hole through a bolt, the position of the large round side of the sleeve can be rotatably adjusted so as to adjust the correct posture of the push rod trolley, and the telescopic push rod 4 is inserted into the hole on the other side of the first sleeve 3. Wherein the large round end and the small hole end of the first sleeve 3 are not provided with threads.

The attachment of the telescopic push rod 4 to the seat 6 is similar to the above. But it uses a second sleeve 5 with a big round end with threads and no threads at the small hole end, so that the threads at the top end of the telescopic push rod 4 are engaged with the threads in the small hole of the second sleeve 5, and the push rod has no freedom along the direction of the push rod.

The support of the seat 6 is supported by a pair of support rods 7 mounted on a retractable rear axle 14: the connection of the support rod 7 and the telescopic rear wheel shaft 14 is realized through a pair of small holes arranged on the telescopic rear wheel shaft (14) and a third sleeve 13 with threads at the large round end, the third sleeve 13 is arranged on the telescopic rear wheel shaft 14 through on-shaft threads, and the support rod 7 is screwed into the small hole end of the third sleeve 13 through threads. The connection of the seat 6 to this support bar 7 is identical to the connection of the telescopic rod 4 for the trolley to the seat 6.

The connection between the telescopic rear wheel axle 14 and the telescopic front wheel axle 15 is realized by connecting a pair of bending support rods 10 with a pair of connecting rods 11, and the bending support rods 10 can share part of the weight born by the telescopic rear wheel axle 14 to the telescopic front wheel axle 15. The connecting rod 11 takes on the function of a fixed structural member. The bending support rod 10 and the connecting rod 11 are respectively connected with the telescopic rear wheel axle 14 and the telescopic front wheel axle 15 through bayonets, so that the convenient disassembly and assembly can be realized.

Two leg placing grooves 16 are arranged on the seat 6, so that the legs of an infant can be placed conveniently. Between the leg slots 16 is a wide band 12 for facilitating the carrying of the case. In addition, the seat 6 is a hard plate material to form a certain strength. But is wrapped with a soft cushion inside and outside the plate material for comfort in sitting and wearing. The backrest 1 is rotatably covered on the seat 6 along the movable shaft to form a suitcase, as shown in fig. 3. The backrest 1 is constructed with canvas and a frame, which has the effect of being comfortable to lean against and not taking up space when the suitcase is formed with increased capacity or little carry.

The wheel 8 is connected with the telescopic rear wheel shaft 14 and the telescopic front wheel shaft 15 through the bearings 9, and the wheel 8 and the telescopic rear wheel shaft 14 and the telescopic front wheel shaft 15 do not need to be disassembled when the bicycle is disassembled and carried.

The disassembly sequence is that the disassembly is from top to bottom: the upper 6 sleeves are detached firstly to take the seat 6 away from the backrest 1; then the telescopic push rod 4 is disassembled; then the seat 6, the telescopic rear wheel shaft 14 and the supporting rod 7 of the telescopic front wheel shaft 15 are disassembled; the bending support shaft 10 and the connecting shaft 11 which are connected between the telescopic rear wheel shaft 14 and the telescopic front wheel shaft 15 are detached again; respectively compressing the telescopic rear wheel axle 14 and the telescopic front wheel axle 15; compressing the telescopic push rod 4; all the components are then either carried in the suitcase formed by the backrest 1 and the seat 6 or carried by the broadband belt 12.

All the connectors are designed to be convenient to disassemble and assemble as much as possible, such as a sleeve and a bayonet. All the disassembled parts can be contained in the suitcase formed by the backrest and the seat, so that the suitcase is convenient to carry and can prevent other articles, and the travel is as simple and convenient as possible. The suitcase can be used as a schoolbag and is carried on the body. The posture of the push rod can be adjusted so as to be used by people with different heights.

The foregoing describes specific embodiments of the present invention. It is to be understood that the invention is not limited to the particular embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the claims without affecting the spirit of the invention.
