Description

multifunctional hand tricycle

technical field

The utility model relates to the field of vehicles, in particular to a multifunctional hand tricycle.

Background technique

Currently used two-wheeled vehicles can be folded, but hand-operated tricycles are not easy to fold, bulky, take up space, and are very inconvenient for storage and transportation. For the elderly and disabled people who often need to use it, they can only be used at home, and it is very inconvenient to carry it when traveling, and the overall carrying will bring a bulky feeling to people, and the restrictions are very large. And the hand tricycle function that uses at present is simple, can only use as a tricycle, and scope of application is not wide. The elderly and the disabled use the two-wheeled handcart under the situation that someone is nursing, and the front hand parts seem redundant.

Contents of the invention

In order to solve the above problems, the utility model provides a detachable multifunctional hand-operated tricycle, which has two functions of a tricycle and a trolley, and is easy to fold and carry.

A multifunctional hand-operated tricycle, including a front wheel and two rear wheels connected by the rear wheel connecting shaft, the front wheel is provided with a hand-operated member, and also includes two front and rear sleeves that can slide and cooperate with each other, the front sleeve It is fixedly connected with the hand crank member, and the rear sleeve is fixedly connected with the rear wheel connecting shaft. The two sleeves are respectively provided with through holes, and the two sleeves are fixed through the through holes by bolts.

Further, the two sleeves are respectively provided with a plurality of through holes.

Furthermore, the two sleeves are fixed by multiple bolts.

Further, the cross sections of the two sleeves are rectangular.

Further, the front casing is provided with a detachable footrest.

Furthermore, the rear wheel connecting shaft is provided with mounting holes for mounting guide wheels and pedals.

The beneficial effects of the utility model are:

Since the connecting shaft of the body of the two-wheeled vehicle and the tricycle adopts a sleeve with a sliding fit and a square section shape, this structure can disassemble the front wheel hand crank mechanism and the folded two-wheel cart mechanism front and rear, which can reduce the space for placement , easy to carry; solve the technical problem that the current folding hand tricycle is not easy to carry.

Since the body connecting shaft is connected by multiple bolts, it can be adjusted telescopically, which not only increases the firmness of the connection, but also adjusts the structure of the distance between the front wheel and the two rear wheels, which can meet the needs of people of different heights. Not only the safety performance is improved, It also brings comfort to people.

A detachable footrest structure for a hand-operated tricycle is installed on the front sleeve, which is convenient for use and storage.

After the front wheel of the utility model is disassembled, a mounting hole for a guide wheel and a pedal is arranged at the front part of the rear wheel connecting shaft, the guide wheel and the pedal can be installed, and the assembly, disassembly and maintenance are all very convenient.

The casing of the device is welded by channel steel, which has low cost and is convenient to manufacture.

Detailed ways

In conjunction with accompanying drawings 1-2, a multifunctional hand-operated tricycle includes a front wheel 1 and two rear wheels 2 connected by a rear wheel connecting shaft 3. The front wheel 1 is provided with a hand-operated member 4, which also includes a The front and rear sleeves (front sleeve 5 and rear sleeve 6) are slidingly fitted, the front sleeve 5 is fixedly connected with the hand-operated member 4, the rear sleeve 6 is fixedly connected with the rear wheel connecting shaft 3, and the two sleeves ( The front sleeve 5 and the rear sleeve 6) are respectively provided with through holes, and the two sleeves (the front sleeve 5 and the rear sleeve 6) are fixed through the through holes by bolts (the two sleeves can also be fitted together The spring buckles are fixed, and the buckles can be separated from each other manually).

When used as a hand tricycle, the front casing 5 and the rear casing 6 are respectively provided with a plurality of through holes, and the depth of the two casings can be inserted into each other according to the needs, and then the bolts can pass through the through holes of the two casings. Fixing (can be fixed with 2 or more bolts at the same time, more firmly), to adapt to the use of people of different heights.

The cross-sections of the two bushings (front bushing 5 and rear bushing 6) can be in any shape such as rectangle, circle, triangle, etc., preferably rectangle, and made of channel steel, which is economical and easy to manufacture, and satisfies the needs of handcarts. strength and stiffness requirements.

In addition, any one of the two bushings (front bushing 5, rear bushing 6) can be provided with a detachable pedal 7, preferably on the front bushing 5, which is convenient for use as a hand tricycle. Also can be provided with the installation hole that guide wheel and pedal can be installed on the trailing wheel connecting shaft 3. When the utility model is used as a two-wheel handcart, guide wheels (may include the connection structure of the guide wheels) and pedals can be installed as required, and the assembly, disassembly and maintenance are all very convenient. The two-wheel cart machine can also be designed to be foldable, which is more convenient for storage.
