Description

Technical Field

[0001] The utility model relates to the field of outdoor transportation tools, and particularly relates to an outdoor trolley and a detachable table board for the outdoor trolley. Background Art

[0002] With the continuous improvement of living standards, short-distance outdoor travel has become a common leisure way for people to relax and get close to nature. In short-distance outdoor travel, a folding trolley is an essential transportation tool. It has two states: folding and unfolding. When folded, it is convenient to transport along with the vehicle. When unfolded, it is convenient to transfer items. In order to further enrich the functions of the folding trolley, many folding trolleys are also equipped with a folding table board. The existing folding table board usually uses the frame of the folding trolley after unfolding as the support main body, and uses buckles and support tubes as the connecting components between the table board and the frame. After installing the support tube on the frame through the buckle, the folded table board is laid flat on the support tube to form a table structure. However, this folding table board still has certain defects in actual application. First, the table board main body and the support tube are separated structures. Although the table board main body can be folded to save transportation space, the length of the support tube is longer than the length of the folding trolley after unfolding and the length cannot be adjusted, which brings inconvenience to the transportation of the table board. Second, since the table board main body is laid flat on the top of the vehicle body, the support by the support tube will completely block the opening on the top of the vehicle body. When only half of the table board is needed, the layout structure of the support tube cannot be changed, resulting in inconvenience in taking items in the vehicle, and there is a problem of poor flexibility in the layout of the table board. Therefore, in order to solve the above problems, it is very practical to provide an outdoor trolley and a detachable table board for the outdoor trolley. Content of the Utility Model

Also, the use of a touch switch will not cause obvious protrusions on the storage side of the tabletop, will not affect the placement of items, and will not affect the flexibility of folding.

[0042] Specific embodiment six: Combining Figures 11 to 21To describe this embodiment, this embodiment provides an outdoor cart. The outdoor cart includes a detachable table board, and also includes a bottom connecting and stretching member 6, a bottom extension board 9, a cart handle 10, a lining cloth bag 11, two L-shaped support plates 5, two side connecting and stretching members 7, and four supporting universal wheels 8. The two L-shaped support plates 5 are arranged oppositely. The bottom connecting and stretching member 6 is arranged between the two L-shaped support plates 5, and each end of the bottom connecting and stretching member 6 is fixedly connected to the horizontal part of the adjacent L-shaped support plate 5. The two side connecting and stretching members 7 are arranged between the two L-shaped support plates 5, and the two side connecting and stretching members 7 are arranged oppositely along the center line in the width direction of the outdoor cart. One end of each side connecting and stretching member 7 is fixedly connected to the vertical part of the adjacent L-shaped support plate 5. The lining cloth bag 11 is arranged in the area surrounded by the bottom connecting and stretching member 6 and the two side connecting and stretching members 7, and the lining cloth bag 11 is detachably connected to the vertical parts of the two L-shaped support plates 5. The four supporting universal wheels 8 are evenly divided into two groups. Each group of supporting universal wheels 8 is correspondingly arranged at the bottom of an L-shaped support plate 5, and the two supporting universal wheels 8 in each group are symmetrically arranged along the center line in the width direction of the outdoor cart.

The bottom extension board 9 is arranged at the bottom of an L-shaped support plate 5, and one end of the bottom extension board 9 is fixedly connected to the bottom of the horizontal part in the L-shaped support plate 5 where it is located. The other end of the bottom extension board 9 extends to the outside of the L-shaped support plate 5. The cart handle 10 is arranged vertically at the top of the other end of the bottom extension board 9, and the bottom of the cart handle 10 is hinged to the top of the bottom extension board 9. Each folding table board unit in the detachable table is correspondingly arranged on an L-shaped support plate 5, and each folding table board unit is inserted into the vertical part in the L-shaped support plate 5 where it is located through an insertion slot 1-1.

[0043] In this embodiment, the connecting and stretching members used in the outdoor cart are all net-shaped stretching structures, which are formed by sequentially hinging multiple X-shaped structures. The stretching and deformation properties of the net-shaped structure are used to connect the two L-shaped support plates 5. The two X-shaped structures at the ends are connected to the L-shaped support plates 5 where they are located through slideways. There are slider structures on the slideways, and the feet of the X-shaped structures are connected to the slideways through sliders, so as to cooperate with the width change of the connecting and stretching member after extension. It should be noted that the connection between the slideway and the slider is a damping connection, and the stretching structure is ensured to be stable through damping friction. And there are limiting structures on the slideways to cooperate with the maximum extension and minimum folding positions of the cart. The lining cloth bag 11 in this embodiment is used in combination with a folding bottom plate. The folding bottom plate is used to lay on the bottom of the lining cloth bag 11 to reinforce the bottom of the lining cloth bag 11 and ensure the stability during loading.

[0045] In this embodiment, the fixed hook 12 is used to hang the inner lining cloth bag 11 and can also limit the insertion plate 1. The length dimension of the insertion plate 1 is equal to the distance dimension between the two fixed hooks 12. When the insertion plate 1 is installed, it is inserted between the fixed hooks 12. The two fixed hooks 12 can prevent the insertion plate 1 and the table board structure from moving in the width direction of the trolley, ensuring the stability of the table board installation.

[0046] The present utility model has been disclosed above with preferred embodiments. However, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the technical solution of the present utility model, can make some changes or modifications to the above-disclosed structure and technical content to form equivalent embodiments with equivalent changes. However, as long as it does not depart from the technical solution of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.

[0047] Working principle

[0048] When this application is in operation, first assemble all components according to the connection relationships described in Embodiment 1 to Embodiment 7 of the specific implementation. It is possible to choose to carry one folding table unit (half table) or two folding table units (full table) according to needs. After arriving at the destination, first unfold the trolley structure and install the folding table unit on the wide side of the outdoor trolley. When arranging the half table, swing the folding board 3 in one folding table unit to the top of the trolley, and ensure that the storage side of the folding board 3 is upward and the support side is downward. Stretch the support leg 4 so that its bottom contacts the inner bottom of the inner lining cloth bag 11 to achieve stable support. Thus, the half table board arrangement is completed. If arranging the full table, swing the folding board 3 in the other folding table unit to the top of the trolley, and also ensure that the storage side of the folding board 3 is upward and the support side is downward (at this time, the other folding table unit does not need to use the support leg, and interference is likely to occur according to the normal trolley structure. If the trolley structure has a large aspect ratio, the support leg can also be used for auxiliary support). After the two folding boards 3 are arranged correspondingly, use the locking pins 3-4 on the sides of the two folding boards 3 to join the two folding boards 3 into a whole. Since the hinge joints inside the folding table unit all adopt the damping hinge setting method, the reliability after the table boards are joined can be guaranteed to the greatest extent. There is still a support leg 4 at the bottom of the overall table board for support, and the support leg 4 is close to the center of the table board, which can also ensure the stability of the table board structure.

[0049] It should be noted that during transportation, the folding table unit, the inner lining cloth bag and the vehicle frame can be separated or pre-assembled together. It is up to the user to decide whether to transport them separately or as a whole according to the space and transportation needs.
