Description
Technical Field
The invention belongs to the technical field of carrying vehicles, and particularly relates to a portable carrying vehicle with adjustable width.
Background
In life, tools such as a trailer and the like have to be used when carrying large goods which are inconvenient to carry, but the trailer is inconvenient to carry, cannot be adjusted in size specifically, and is inconvenient to use in certain situations.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a portable carrier with freely adjustable width, which has the characteristics of simple structure, convenience in adjustment, portability and use.
In order to solve the technical problems, the invention adopts the technical scheme that: a portable carrier with adjustable width comprises two wheels which are coaxially arranged; a second connecting block with a hollow interior is arranged at the inner shaft end of the left wheel; a first connecting block is arranged at the inner shaft end of the right wheel; two sides corresponding to the inner cavity wall of the connecting block I are respectively provided with a hemispherical groove; and a plurality of groups of springs vertical to the shaft are arranged in the inner cavity of the first connecting block, and two ends of each group of springs are respectively connected with a metal ball.
The second connecting block is in telescopic connection with the first connecting block; and when the second connecting block is fixedly connected with the first connecting block, the metal balls at the two ends of the spring extend into the hemispherical groove on the wall of the inner cavity of the first connecting block.
The two metal balls at the two ends of each group of springs are positioned on the same axis.
The semi-spherical grooves on the inner walls of the two connecting blocks are arranged at intervals, and the radius of the semi-spherical grooves is slightly smaller than that of the metal balls.
And the contact plates are respectively arranged on the second connecting block and the first connecting block, and the contact surfaces of the contact plates for fixing goods are made of rubber materials.
And a handle is arranged on the axle center at the outer side of the wheel.
The invention has the beneficial effects that:
the invention is provided with a structure that the connecting block II is telescopically connected with the connecting block I; the small ball in the connecting block can be moved to another groove to be fixed again by holding the handle to give certain external force stimulation, so that the structure has the characteristic of being capable of adjusting the width of the trolley.
The contact surface of the contact plate for fixing the goods is made of rubber materials, so the contact plate has the characteristics of increasing friction force and better fixing the goods.
Since the radius of the semi-spherical groove is slightly smaller than that of the metal ball, the metal ball can be fixed in the semi-spherical groove so as to fix the whole telescopic block, and when the given force exceeds a certain limit, the metal ball can be moved into another group of semi-spherical grooves so as to change the length of the telescopic block.
The handle fixed on the axle center of the wheel is round, so the handle can be conveniently grabbed by hands when the length of the handle is required to be stretched, and the grabbing is more convenient.

Detailed Description
The invention will be described in further detail with reference to the drawings and examples
Referring to fig. 2, a portable cart with adjustable width comprises two wheels 5 coaxially connected; a hollow connecting block II 3 is arranged at the inner shaft end of the left wheel 5; a first connecting block 2 is arranged at the inner shaft end of the right wheel 5; a group of semi-spherical grooves 7 are respectively arranged on two sides corresponding to the inner cavity wall of the first connecting block 2; a plurality of groups of springs 1 vertical to the shaft are arranged in the inner cavity of the connecting block I2, and two ends of each group of springs 1 are respectively connected with a metal ball 8; a contact plate 4 for fixing goods, a pair of wheels 5 and a handle 6 which is convenient to extend and retract and is used for being grasped by hands.
The second connecting block 3 is in telescopic connection with the first connecting block 2; and when the second connecting block 3 is fixedly connected with the first connecting block 2, the metal balls at the two ends of the spring 1 extend into the hemispherical grooves 7 on the wall of the inner cavity of the first connecting block 2. One group has two hemispherical grooves 7, and the two hemispherical grooves 7 are respectively matched with two metal balls at two ends of each group of springs.
The second connecting block 3 connected with the two wheels and the first connecting block 2 are combined together to be telescopic.
The two metal balls at the two ends of each group of springs 1 are positioned on the same axis.
The hemispherical grooves 7 on the inner wall of the second connecting block 3 are arranged at intervals, and the radius of the hemispherical grooves 7 is slightly smaller than that of the metal ball.
The upper parts of the second connecting block 3 and the first connecting block 2 are respectively provided with a contact plate 4, and the contact surface of the contact plate 4 for fixing goods is made of rubber.
The handle 6 is arranged on the axis of the outer side of the wheel 5, and the shape of the handle is smooth, so that the handle can be conveniently grabbed by hands.
The length of the trolley is adjusted by holding the handle 6 with two hands and forcibly pushing the handle to enable the contact plate 4 to be tightly attached to the goods, and a plurality of pairs of trolleys can be added to the goods according to the situation. The trolley can be tightly fixed on the goods under the proper length, and the goods provided with the wheels can be moved conveniently.
The carrier is provided with two rollers, handles convenient to hold are arranged on the edges of the two rollers, contact plates for fixing goods are respectively arranged on the inner sides of the rollers, and a first connecting block and a second connecting block which are connected with the two rollers are of a telescopic structure; the inner wall of the inner connecting block II is uniformly provided with a hemispherical groove, and a plurality of pairs of metal balls connected by springs are arranged in the outer connecting block I. The metal ball can move from the semi-spherical groove to the next semi-spherical groove for fixing by holding the handrail and pushing and pulling forcibly.
The working principle of the invention is as follows:
when the length of the connecting block of the trolley needs to be stretched, a user holds the handle 6 by hand to stretch outwards, when the applied force is a certain degree, the metal ball 8 with the radius slightly larger than the semi-spherical groove 7 can be separated from the current semi-spherical groove 7, and when the metal ball moves to the outer group of semi-spherical grooves 7, the metal ball has the radius slightly larger than the radius of the semi-spherical groove 7, and can be clamped in the new semi-spherical groove 7, so that the connecting block of the trolley is stretched.
Similarly, when the length of the connecting block of the trolley is to be shortened, the handle 6 is held by a hand to push inwards, when the force reaches a certain degree, the metal ball 8 with the radius slightly larger than that of the hemispherical groove 7 can be separated from the current groove, and when the metal ball moves to the inner group of hemispherical grooves 7, the metal ball can be clamped in the new hemispherical groove 7 because the radius of the metal ball is slightly larger than that of the hemispherical groove 7, so that the connecting block of the trolley is shortened.
Firstly, the trolley is stretched to a length slightly longer than that of the goods, then one contact plate 4 of the trolley is enabled to be tightly attached to the goods, the handles 6 on the two sides are pressed by the two hands, the length of the trolley is shortened until the two contact plates 4 can be tightly attached to the goods, so that the carrier is fixed on the goods, and the successful assembly of the carrier on the goods can be very convenient when the goods are dragged.
The basic idea and the basic principle of the invention have been explained above by way of an introduction to the embodiments listed. The present invention is not limited to the above-mentioned embodiments, and all equivalent changes, modifications and deliberate deterioration actions based on the technical solution of the present invention should fall within the protection scope of the present invention.
