Detailed Description
The application is described in further detail below with reference to fig. 1-4.
The embodiment of the application discloses a foldable four-wheel draw-bar box.
Referring to fig. 1, a foldable four-wheel draw-bar box includes four end-to-end connected side plates 1, a bottom plate 2 positioned at the bottom of the side plates 1, and a cover plate 3 positioned at the top of the side plates 1. The four side plates 1 and the bottom plate 2 enclose a containing chamber 4 for placing articles. The side panel 1 in turn comprises a front side panel 11, a rear side panel 12 and two intermediate side panels 13 located between the front side panel 11 and the rear side panel 12.
Referring to fig. 1 and 2, the cover plate 3 is rotatably coupled to the front side plate 11 such that the cover plate 3 has a closed state and an open state. When the cover plate 3 is in the closed state, the cover plate 3 is positioned above the accommodating chamber 4 and covers the accommodating chamber 4, and the cover plate 3 vertically abuts against the top surface of the rear side plate 12. When the cover plate 3 is switched from the closed state to the open state, the cover plate 3 is turned outward in a direction away from the housing chamber 4 and is abutted in parallel with a side of the front side plate 11 away from the rear side plate 12.
Referring to fig. 1 and 2, in order to prevent the cover plate 3 from moving when it abuts against the front side plate 11, the cover plate 3 and the front side plate 11 are locked by a locking structure so as to reduce the probability of damage caused by collision friction between the cover plate 3 and the front side plate 11. The outer side surface of the front side plate 11 is provided with a buckle 111, the buckle 111 is a square block, and the cover plate 3 is provided with a slot 31 which can be matched with the buckle 111 in a clamping way and is matched with the buckle 111 in shape. The number of the buckles 111 is two, the buckles are symmetrically arranged on the front side plate 11, and the slots 31 are arranged in one-to-one correspondence with the buckles 111.
Referring to fig. 1 and 2, the cover plate 3 is provided with a guide slope 32 at the notch of the slot 31, and the width of the slot 31 at the notch is greater than the width in the slot 31, so that the insert buckle 111 is more easily caught in the slot 31.
Referring to fig. 2 and 3, the bottom plate 2 is rotatably coupled to the front side plate 11 such that the bottom plate 2 has a flat state and a storage state. When the bottom plate 2 is in a flat state, the bottom plate 2 is positioned below the accommodating chamber 4, and the bottom plate 2 is vertically arranged with the front side plate 11, the rear side plate 12 and the middle side plate 13, so that articles can be placed on the bottom plate 2, and the bottom plate 2 supports the articles. The bottom of the intermediate side plate 13 has a support portion 131, and the support portion 131 is a bar-shaped block arranged horizontally. When the bottom plate 2 is laid flat, the bottom surface of the bottom plate 2 is abutted with the top surface of the supporting part 131, so that the bottom plate 2 is not easy to overturned excessively.
Referring to fig. 2 and 3, when the bottom plate 2 is in the housed state, the bottom plate 2 is turned over to abut in parallel with the inner side of the front side plate 11. The arrangement cavity 112 is formed in the inner side wall of the front side plate 11, and the bottom plate 2 can be stored in the arrangement cavity 112, so that the storage box is small in size when the bottom plate 2 is in a storage state.
Referring to fig. 3 and 4, the intermediate side plate 13 includes a plurality of rotation units 132, and the rotation units 132 are rotatably connected to each other such that the intermediate side plate 13 has a folded state and an unfolded state. The plurality of rotation units 132 are disposed in parallel when the intermediate side plate 13 is in the unfolded state. When the intermediate side plate 13 is in the folded state, the rotating unit 132 is turned and folded toward the housing chamber 4, and the rotating units 132 abut against each other, so that the rotating unit 132 is housed between the front side plate 11 and the rear side plate 12.
In the present embodiment, the number of the rotation units 132 is two, and the switching between the folded state and the unfolded state can be completed by folding the rotation units 132 once. The number of the rotating units 132 may also be four, six, etc. that enable rotational folding, the number being an even number.
In order to make it difficult to switch to the folded state when the intermediate side plate 13 is in the unfolded state without being manually operated, a fixing piece 133 for locking the rotation unit 132 in the unfolded state is provided on the intermediate side plate 13. The rotating units 132 are provided with slide ways 134, the slide ways 134 are connected with each other, and the fixing pieces 133 are slidably arranged on the slide ways 134. When the middle side plates 13 are in the unfolded state, the fixing pieces 133 are located at the connection positions of the rotating units 132, and a part of the fixing pieces 133 are arranged on the slideway 134 of each rotating unit 132, so that the rotating units 132 cannot rotate. When the middle side plate 13 is in a folded state, the fixing piece 133 is slidably disposed with one of the rotating units 132, so that the rotating units 132 can rotate with each other and fold and store.
Referring to fig. 2 and 4, the intermediate side plate 13 is rotatably connected to the front side plate 11 and the rear side plate 12, respectively, so that the storage box has a storage state and a spread state. When the storage box is in the open state, the bottom plate 2 is in the flat state, the middle side plate 13 is in the unfolded state, and the storage chamber 4 can store articles. When the containing box is in a containing state, the cover plate 3 is in an open state, the bottom plate 2 is in a containing state, the middle side plate 13 is in a folding state, a gap between the front side plate 11 and the rear side plate 12 can be reduced, and finally the front side plate 11 is in parallel butt joint with the rear side plate 12, so that the whole volume of the containing box is smaller.
When placing article in the containing box, holistic weight is heavier, in order to be convenient for the removal of containing box, the bottom of preceding curb plate 11 and posterior lateral plate 12 all is provided with gyro wheel 5 for the containing box can slide subaerial. The roller 5 on the front side plate 11 is in the form of a universal wheel 51, and the roller on the rear side plate 12 is in the form of a fixed pulley 52, so that the roller is convenient to turn and slide when moving on the ground of the storage box. The rear side plate 12 is also provided with a pull rod handle 6, and the pull rod handle 6 is arranged on the rear side plate 12 in a telescopic sliding manner. When the storage box does not move, the pull rod handle 6 can be contracted and shortened, so that the storage box is small in size. When the storage box needs to be moved, a user can pull the storage box to move on the ground through the pull rod handle 6, so that the storage box is convenient.
Referring to fig. 1 to 4, the steps of receiving a foldable four-wheel draw-bar box according to an embodiment of the present application are:
1. The cover plate 3 is turned over to be in an open state, and the cover plate 3 is in parallel abutting connection with the outer side of the front side plate 11;
2. The bottom plate 2 is folded to be in a storage state, and at this time, the bottom plate 2 is stored in the arrangement cavity 112 of the front side plate 11;
3. The rotation unit 132 of the intermediate side plate 13 is rotated to be in a folded state, and at this time, the rotation is brought into abutment with each other and accommodated between the front side plate 11 and the rear side plate 12;
4. the space between the front side plate 11 and the rear side plate 12 is reduced so that the front side plate 11 and the rear side plate 12 are in parallel contact with each other, and the storage box is in a storage state.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
