Description

TECHNICAL FIELD

[0001] The present application relates to the field of trolley technology, in particular to a combined trolley. BACKGROUND

[0002] When people go to the wild, they will carry a variety of items, such as cooking utensils, beverages, clothes, tents, children's supplies, towels and food, etc. When the vehicle arrives at the camping location, the required items need to be transported from the vehicle to the camping site. However, the space of a general family car is limited and cannot carry a large amount of supplies. The best configuration for going out camping is to carry an outdoor trolley for camping, and also to carry outdoor tables and chairs for camping, plus the regular items for a picnic, food, etc. The trunk of the car cannot carry so many supplies at all. Even if the tables and chairs for camping can be folded, it is difficult to put them all down. Therefore, some non-essential items are usually discarded, such as using a picnic mat instead of a table and chair, using manpower instead of an outdoor camping trolley, and only placing the picnic supplies in the car.

[0003] When people go camping outdoors, they can only sit on the ground and bend over, which can cause muscle strain and discomfort. In addition, the picnic cannot be carried out at some places where the ground is not clean because the picnic mat cannot be used. It is necessary to choose another place, which limits the picnic and camping. It is also very tiring to carry the items from the car to the picnic or camping site. However, the size of the camping trolley is generally large and difficult to carry, which brings inconvenience to camping and makes it difficult to transport supplies. Even if some camping trolleys can be folded to be smaller, they still occupy a lot of space.

[0065] In one specific embodiment of the present application:

[0066] The embodiment of the present application provides a combined cart, and the technical problems encountered by the present application are: 1. During camping and picnic, it is laborious to carry video and other materials, especially in the deep part of the park that some cars cannot reach, and it is difficult for people to carry a large amount of scattered materials at one time, and it is also difficult to carry too heavy objects at one time, which brings inconvenience to camping and picnic. The volume of the camping cart is generally large, and it is difficult to carry. If the camping cart is carried, the space of other materials will be occupied, and there is no more material to be carried by the cart. Although it is labor-saving, more space is occupied, which leads to inconvenience of carrying materials by car; 2. Generally, the camping cart and the camping table and chair can only carry one kind of equipment, most people will choose to carry only the table and chair. When the carried object is heavy, the same choice will be faced. No matter which one is chosen, the other one will be carried, and the other one will be carried.

[0067] The technical problem solved by the present application is that the bench board, the short chair board and the table board can be assembled into a cart by simple assembly, and can be folded into multiple small flat plates for separate storage after being disassembled, which occupies less space, and is convenient to carry and assemble.

[0068] The technical effects realized are: 1. The bench board 1, the short chair board 2 and the table board 3 of the present application can be assembled with the wheels 4 and the bolts 5 into a complete small cart for transportation and use of materials, which is convenient to use. The handrail rod 22 can be extended in the rear short chair leg 21, which is convenient to push and pull the cart. The front short chair leg 21 can be stably extended horizontally, which can be used as a storage rack for support, and can also carry children, which is more flexible and convenient to use;

[0069] 2. The bench board 1, the short chair board 2 and the table board 3 of the present application can be disassembled for separate use. The unfolded bench leg 11, short chair leg 21 or table leg 31 can become a separate chair and table for use, which brings comfortable seats and tables for camping and picnic, effectively alleviating the fatigue caused by sitting on the ground, and is more convenient to use;

[0070] 3. The bench leg 11, short chair leg 21 or table leg 31 of the present application can be folded back to form a flat plate state. The flat plate structure can be conveniently stored in the trunk of the car, can be placed under the materials, or can be inserted between the cracks. After being folded into a flat plate, the flat plate bench board 1, short chair board 2 and table board 3 can be disassembled and stored in the trunk of the car, which can be flexibly stored separately or stacked together. The whole structure of the car is no longer occupied, so that the present application is more flexible in storage and can be flexibly adjusted according to the different materials carried.

[0089] In order to facilitate description, the front side of the device is the front side assembled as a trolley, the rear side is the side of the handrail 22 held by the hand, and the left and right sides are the left and right sides when the trolley travels, the inside is the inside of the trolley in the trolley state, the outside is the outside of the trolley, the top is the top of the table and chair used alone after being split, and the bottom is the side facing the ground in the table and chair placing state; because the device is assembled, the front and rear can be transposed according to the assembly mode, so the front and rear cannot be limited, but only for easy description.

[0090] The two long chair plates 1, the two short chair plates 2 and the table plate 3 of the device can be split into separate individuals, only the two long chair plates 1, the two short chair plates 2 and the table plate 3 and the four wheels 4 are split into separate structures by rotating all the bolts 5.

[0091] When the device is split and used, the short chair legs 21 are turned over and unfolded on the bottom surface of the short chair plate 2, so that the two short chair legs 21 form effective support, and the handrail 22 is retracted in the short chair leg 21; similarly, the long chair plate 1 and the table plate 3 are also disassembled, and the long chair legs 11 on both sides are unfolded on the bottom surface of the long chair plate 1 to be attached; the table legs 31 on both sides of the bottom surface of the table plate 3 are also turned over and unfolded, and are attached to the bottom surface of the table plate 3 to support, and the support legs on the bottom of all the long chair plates 1, the short chair plates 2 and the table plate 3 are 105° with the bottom surface, which is more stable, conforms to the human sitting posture, and will not be retracted.

[0092] The short chair leg 21 is retracted at the bottom surface of the short chair plate 2, and the other short chair leg 21 can also be folded and stored as a flat plate, or can be directly stored in an open state. Because the two short chair legs 21 are of the same length, the two short chair legs 21 will interfere with each other, and the two short chair plates 2 are of the same structure, so that one side is opened during storage. The handrail rod 22 is also retracted in the short chair leg 21, and the short chair leg 21 and the handrail rod 22 are commonly used spring pins for clamping. It belongs to a commonly used structure, and has the same structure as the telescopic rod. The locking mode is not limited. It can be locked by spring pins and clamping holes, or other similar telescopic structures can be used for locking.

[0093] The long chair plate 1 and the table plate 3 are also detached, and the long chair legs 11 on both sides are folded and retracted on the bottom surface of the long chair plate 1.

[0094] When the invention is assembled for use as a trolley, two long chair plates 1, two short chair plates 2 and a table plate 3 are all detached and stored as folded flat plates. The bottom surface of the table plate 3 is placed on the top of the receiving plate 43, and the receiving plate 43 covers the folded table legs 31 to prevent the table legs 31 from opening downward. The side baffle 41 is provided with two positioning holes 44 and a clamping groove 42.

[0095] The clamping groove 42 is a square opening that opens to one side, and the clamping groove 42 does not cut off the side baffle 41. The positioning hole 44 is used for passing a bolt 5, and also needs to be horizontally provided, that is, the axes of the two positioning holes 44 need to be parallel to the bearing plane of the receiving plate 43.

[0096] During assembly, the lower positioning hole 44 is locked with a bolt 5, and the bolt 5 passes through the side baffle 41 and is locked in the locking hole 32 at the front and rear ends of the table plate 3. There are at least four locking holes 32 at the front and rear ends of the table plate 3. Each locking hole 32 needs to be locked with a side baffle 41 and a bolt 5, so as to lock the roller 4 with the table plate 3 and limit the table legs 31, so that they will not open downward after assembly.

[0097] Then the long chair plate 1 is assembled, the two long chair plates 1 are butted on the left and right sides of the top of the table plate 3, and the planes of the two long chair plates 1 are parallel to each other. At this time, the top of the table plate 3 is only open at the front and rear sides and the top. Then the short chair plate 2 is vertically placed, the short chair leg 21 is placed in an up-down orientation, and the short chair plate 2 is covered on the openings at the front and rear sides of the top of the table plate 3. The openings at the front and rear sides are sealed, so that the planes of the adjacent long chair plate 1, short chair plate 2 and table plate 3 are perpendicular to each other and are butted stably. After splicing, a vehicle hopper with an open top is formed, and the vehicle hopper is a rectangular box composed of two long chair plates 1, two short chair plates 2 and a table plate 3.

[0098] When the bench plate 1 is placed vertically, the end lock holes 12 on the same end surface become distributed vertically, and similarly, when the short bench plate 2 is placed vertically, the assembly holes 23 are also distributed vertically on the four corners of the short bench plate 2, and each assembly hole 23 penetrates through both sides of the short bench plate 2,

[0099] When the bottom of the bench plate 1 is stably supported by the supporting plate 43, the assembly hole 23 below the short bench plate 2 is aligned with the end lock hole 12 below the bench plate 1, and the positioning hole 44 below the side stop plate 41 is also aligned, and at this time, the axes of the three holes are on the same horizontal line, then the bolt 5 is sequentially inserted through the positioning hole 44 below and the assembly hole 23 below the short bench plate 2, and locked in the end lock hole 12 below the bench plate 1, to ensure firm locking, thereby locking the side stop plate 41, the short bench plate 2 and the bench plate 1 firmly, and at this time, the bench plate 1 and the short bench plate 2 form an integral force structure with the side stop plate 41 and the supporting plate 43 and the table plate 3; in the same way, the bench plate 1 on both sides is locked with the short bench plate 2 and the table plate 3 by the bolt 5, and the short bench plate 2 at the front and back is also locked firmly.

[0100] Only the different operation is that the upper short bench leg 21 of the rear short bench plate 2 needs to be opened and raised, so that the upper short bench leg 21 is in an open state, and the lower short bench leg 21 needs to be folded and attached to the short bench plate 2, and the short bench leg 21 is attached to the outer side of the short bench plate 2, then the assembly hole 23 on the upper side of the short bench plate 2 is directly locked with the end lock hole 12 on the upper side of the bench plate 1 by the bolt 5, and the upwardly opened short bench leg 21 is clamped by the hand-tightened bolt 5 to prevent the short bench leg 21 from being folded downward, and the hand-tightened part of the hand-tightened bolt 5 is large enough to block the short bench leg 21 from being folded downward.

[0101] The upper short bench leg 21 of the rear short bench plate 2 is folded downward to attach the upper short bench leg 21 to the short bench plate 2, and the short bench leg 21 is also outside the vehicle body, and is locked by the hand-tightened head of the hand-tightened bolt to prevent it from being unfolded, thereby locking the upper side of the short bench plate 2 to the upper side of the bench plate 1;

[0102] The front-to-back length of the bench plate 1 is the same as the front-to-back length of the table plate 3, and the left-to-right width of the short bench plate 2 is the same as the left-to-right width of the table plate 3, which facilitates tight butt joint.

[0103] The lower short bench leg 21 of the short bench plate 2 needs to be folded downward, and the short bench leg 21 is inserted through the clamping groove 42 on both sides, and the clamping grooves 42 on the left and right sides of the rear side stop plate 41 are opened inward, so that the short bench leg 21 can be stably clamped, and the lower short bench leg 21 is unfolded horizontally, which can accommodate other boxes and other items, and can also allow children to ride.

[0104] Thus, the whole trolley is assembled, simple and firm structure, convenient to use, after assembling as trolley, the carried materials can be transported, labor saving and convenient, and the trolley can be disassembled as independent components after reaching the destination, and the materials can be taken out from the trolley, and the trolley can be disassembled as independent components, unfolded as table and chair, and folded as flat plate during the journey, so that the space occupation is small, and the outdoor camping and picnic are more convenient.
