And a stereotactic connecting rod set 4 provided between the front body 1, the rear body 2, and the handle 3. A seat 5 is provided slightly above the front body 1 so that even adults can sit on it. When the wheelbarrow is folded, the front body 1 and the rear body 2 are drawn to each other by the interlocking of the stereoscopic connecting rod set 4 if the handle 3 is pulled down to the rear, and the handle 3 is perpendicular to the rear body 2 , And the seat 5 is vertically adjacent to the front vehicle body 1 and is in a folded state, so that the volume is very small. Conversely, when the handle 3 is to be spread, the handle 3 is pulled up, and the stereotactic connecting rod assembly 4 is easily spread in conjunction with it, and the operation is convenient.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wheelbarrow.

[0002]

[Prior art]

 Traditionally, most shopping trolleys used in general supermarkets are just for storing things to buy, and there is no seat to sit if an old woman is tired of walking around. Some can carry small children, but few have wheelbarrows where adults can sit.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide a wheelbarrow that has a seat that can be seated by an adult, and that can be folded and takes up little space for storage.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, a wheelbarrow according to the present invention has wheels provided at both lower ends of a front body, both upper ends are pivotally connected to two lower ends of a handle, and the handle is provided at the rear. So that it can be folded down. In addition, by installing wheels at both lower ends of the rear body and pushing the handle, the shopping trolley can move on the ground, and furthermore, a stereotactic connecting assembly that pivotally connects the front body, rear body and the handle. The stereotaxic connection set allows the shopping cart to be spread and used or folded down to minimize the volume for convenient storage. The locating connecting rod set is composed of two locating tools fitted to both lower ends of the handle and movable up and down, a two connecting rod connecting the locating tool and two movable sleeves fitted to both upper ends of the rear body, An interlocking rod is provided which is U-shaped and has both sides pivotally connected to the rear vehicle body and both front ends pivotally connected to middle portions of both sides of the front vehicle body. In addition, the seat will be pivotally mounted on the slightly upper part of the front body so that the person can sit on it.

[0005] With the above structure, when folding a handcart, if the handle is pulled down to the rear, the front body and the rear body are drawn together by the interlocking of the localization connecting rod set, and they are adjacent to each other. The seat is vertically adjacent to the rear body and the seat is folded vertically adjacent to the front body, so that the volume is very small. The stereotactic connecting rod set is linked by raising the handle to the front so that the shopping cart can be extended and used, and the handle can be pulled down to the rear and folded.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The wheelbarrow according to the embodiment of the present invention comprises a front body 1, a rear body 2, a steering wheel 3, a stereoscopic connecting rod set 4, a seat 5, and a shopping bag 6, as shown in FIGS. It is composed of a combination of parts.

The front vehicle body 1 is provided with wheels 10 at both lower ends, both upper ends are respectively connected to both lower ends of a handle by assembling a connecting tool 11, and the upper end of the connecting tool 11 has a fixing projection 12. The rear body 2 has wheels 20 at both lower ends, and seats 5 are attached to both upper ends. The fixed rod set 4 is configured by combining two localization tools 40, two connection rods 41, two movable sleeves 42, and an interlocking rod 43. Each of the positioning tools 40 is fitted on the outer periphery of the two lower ends of the handle, and further has a pulling tool 400 and a fixing hole 401 at the lower end.

The upper ends of the two connecting rods 41 are pivotally connected to the positioning tool 40. The interlocking rod 43 is U-shaped, and its left and right sides are pivotally connected to a movable sleeve 42 fitted to the two upper ends of the rear vehicle body, and are pivotally connected to the front vehicle body 1 at a location near the opening, and the front end is a seat. It is pivotally connected to the left and right front ends of the seat 5. Further, the upper periphery of the shopping bag 6 is connected to the connecting rod.

As shown in FIG. 2 to FIG. 5, when folding the handcart, first put a finger into the pulling tool 400 of the localization tool 40 and pull up the positioning tool 40, and fix the fixing hole 401 to the front vehicle body 1. Separate from the fixed base 12. FIG. 3 illustrates this. Next, pull down the handle 3 in the rearward direction as shown in FIG. At this time, the connecting rod 41 pulls down the localization tool 40, and at the same time, the movable sleeve 42 swings down the interlocking rod 43, and simultaneously pulls the front and rear bodies 1, 2 inward. Further, the seat 5 is folded on the front vehicle body 1 and is completely folded as shown in FIG.

[0010] On the contrary, when the handle 3 is used in a state of being expanded from a folded state, as shown in FIGS. 2 to 5, first, the handle 3 is pulled upward and the stereotactic connecting rod set 4 is also moved upward. , The positioning tool 40 also moves upward, and the connecting rod 41 is pulled up. Therefore, the connecting rod 41, the movable sleeve 42, and the interlocking rod 43, which are pivotally connected to each other, simultaneously cooperate to extend the front vehicle body 1 and the rear vehicle body 2 outward, thereby bringing the seat 5 to a horizontal state. At this time, the handle 3 and the front vehicle body 1 have a straight inclined shape (shown in FIG. 3). Therefore, a finger is put on the pulling device 400 of the positioning device 40, and the positioning device 40 is pulled down and fixed as shown in FIG. When the hole 401 is fitted to the fixed base 12 of the front vehicle body 1, the wheelbarrow is in an expanded state and can be used.

[0011]

[Effect of the invention]

 The present invention has the following effects. 1. It is extremely easy and convenient to fold or unfold, just pull the handle down or up. 2. This wheelbarrow has brakes and seats, and it is convenient for the user to sit and rest when tired. 3. The stereotactic connecting rod set works effectively and accurately, so that the folding and unfolding operations are ensured and the safety of the wheelbarrow is improved.
