There are many forms of folding tables. For example, there is a folding table in which the desktop and the table frame are designed separately. The two can be separated from each other. During installation, two cross bars are overlapped on the table frame to support the desktop ( The crossbar is generally set along the long axis of the table frame).

For example, Chinese Patent No. 202121903491.2 discloses a folding square table bracket structure, which includes a folding table frame, a connecting piece and a support rod. When the folding table frame is in the unfolded state, a connecting piece is provided in the middle of the two long sides of the upper surface. There are four support rods in total. One end of the support rod is pivotally connected to the long end of the upper surface of the folding table frame, and the other end of the support rod is movably connected to the connecting piece. When folding the above-mentioned folding square table or this type of folding square table, it is necessary to fold the outer end of the support rod outwards on the pivot piece and then retract it downward (since the support rod is located directly above the folding rod, when the support rod is folded, (can only be folded outward). When opening the folding table, fold it from bottom to top and from outside to inside and then support it. During the folding and opening process of the table frame, the support rod needs to be moved outwards on both sides of the bracket in a large manner. The folding action requires a large folding space, which is inconvenient to operate. If the internal space of the tent is small, the operation will be difficult.

Implementation

In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

As shown in Figures 1 and 2, the present invention discloses an improved folding table structure, which includes a foldable table frame 1 and a table plate 2 supported above the table frame. The table 2 is a foldable table. The table 2 can include a plurality of long strips 21 arranged side by side and elastic connecting ropes (not shown in the figure) that can connect the long strips 21 in sequence. 2 Can be rolled up to reduce storage volume.

As shown in FIGS. 1 to 7 , which is a first embodiment of the present invention, the table frame 1 includes four table legs 11 forming a rectangular four-corner distribution. One set of opposite sides is defined as the longitudinal side, and the other set of opposite sides is defined as the transverse side. , the two table legs in each longitudinal side and each transverse side are respectively connected by at least one set of foldable cross strut sets 3. The two table legs 1 on the longitudinal side are connected by at least two sets of foldable cross strut groups 3. In this embodiment, two groups of cross strut groups 3 are provided on the longitudinal side, and one group is provided on the transverse side. Cross strut set 3. Each cross strut group 3 includes two diagonal struts 31 that are pivotally connected in the middle. The top of each table leg 11 is connected to a fixed connection base 12, and the bottom of the fixed connection base 12 is also connected to a slider that can slide on the table leg 11. The movable connecting base 13 allows the movable connecting base 13 to be positioned on the table leg 11 after the cross strut group 3 is deployed. In the longitudinal side, in the two connected cross strut groups 3, the inner ends of the oblique struts 31 are pivoted to form an upper connection point and a lower connection point, and the outer ends of the oblique struts 31 are respectively connected to the fixed connection base 12 and the movable connection base 12. On the connecting base 13. For a single set of cross struts, such as the transverse side of this embodiment, the upper end of the oblique strut 31 is connected to the fixed connection base 12 and the lower end is connected to the movable connection base 13 . In each facade formed by the table legs 11, each table leg 11 is driven by the cross strut group 3 to merge, retract and unfold.

In the present invention, a horizontal support rod 41 is rotatably connected to the top of the two table legs 11 in the longitudinal side. In this embodiment, the cross support rod group 3 is located between the two table legs 1, and the oblique support rod 31 is connected to the table. The legs are located on the same plane, and the cross strut 41 is arranged on the outer surface of the top of the table leg 11. Of course, the cross strut 41 can also be arranged on the inner surface of the top of the table leg. In addition, in the longitudinal side, if the cross strut group 3 is arranged on the front or rear side of the table leg, the transverse strut 41 can also be disposed on the top of the table leg 11 and folded inward, or the transverse strut 41 can be folded inward and downward. It is arranged on the opposite surface to the cross strut group (for example, the cross strut group is located on the front side of the table leg, and the cross strut is located on the rear side of the table leg). As long as it is staggered with the cross strut group 3 and does not cause conflict, it satisfies The horizontal support rod 41 can be folded inward. The inner ends of the two horizontal struts 41 can be connected to each other to form a horizontal bar 4, so that the table 2 is set up between the two horizontal bars 4. In this embodiment, the cross bar 4 is located on the outside of the cross strut group 3 on the longitudinal side. The outer end of the cross strut 41 is rotatably connected to the outer surface of the fixed connection base 12. The cross strut 41 and the cross strut Group 3 is staggered, so that the two horizontal struts 41 can be separated and folded inward when the table legs 11 are retracted (as shown in Figure 5). The two horizontal struts 41 of the same horizontal bar 4 can be directly connected to each other, so that the inner end of one of the horizontal struts 41 forms a socket section 411 that can be sleeved into the inner end of the other horizontal strut 41. The connecting section 411 forms a constriction section that can be inserted into the inner end of another horizontal support rod 41 . When the table frame needs to be folded, the middle part of the cross bar 4 is pulled outward to separate the two cross struts 41. On the contrary, the two cross struts 41 are connected in the middle part, making the connection structure simpler.

Further, an elastic rope 42 is connected between the two horizontal struts 41 of the same horizontal bar 4. The elastic rope 42 has tensile elasticity when the two horizontal struts 41 are separated. By adding the elastic rope 42, when the table frame is to be opened, the inner end of the two horizontal struts 41 as the movable end can automatically rise as the table frame is opened under the pull of the elastic cord 42, which can assist the connection of the two horizontal struts 41. combination, the movement is smoother; when the two horizontal struts 41 are disengaged, the horizontal struts 41 rotate downward and fold respectively. Under the elastic force of the elastic rope 42, the ends of the two horizontal struts 41 can always be close together. , and also prevent the two horizontal struts 41 from being separated.

Furthermore, in order to make the support of the two longitudinal sides of the table frame more stable, in the present invention, in each longitudinal side, the two sets of cross strut groups 3 are provided with a support member 5 at the upper connection point located above the intersection connection. As shown in FIGS. 8 and 9 , the support member 5 is provided with a slot 51 that can support the crossbar 4 . The slot 51 can support the crossbar 4 and block the crossbar 4 at the same time. The bottom surface of the support member 5 can also be provided with two limiting grooves 52. The two sets of cross strut groups 3 are at the intersection connection, and the upper ends of the two crossed diagonal struts 31 are respectively limited in the limiting grooves 52 (as shown in Figure 3 , as shown in Figure 4), to prevent the cross strut group 3 from shaking. The clamping slot 51 is located above the limiting slot 52 and on one side of the limiting slot 52. In this embodiment, the clamping slot 51 is located outside the limiting slot 52. The two oblique struts 31 can be pivoted in the limiting slot 52 respectively. , after the table is opened, the limiting groove 52 resists the inclined support rod 31 and also keeps the support member 5 horizontal. By pivotally connecting a support member 5 at the upper part of the intersection of the two cross strut groups 3 in the longitudinal side, when the table frame 1 is opened, the support member 5 has a clamping groove 51 and a limiting groove 52, and the cross bar 4 It can just fall on the support member 5 to support the cross bar 4 and at the same time, the cross strut group 3 can be fixed below the cross bar 4 without shaking.

As shown in Figure 2 and Figures 5 to 7, when the present invention is used, when the folding table is to be folded, the table board 2 is first picked up and then rolled up. When the table frame 1 is folded, it will be located on the longitudinal edge. The two cross bars 4 are disassembled respectively, and the cross bar 4 is pulled outward at the middle connection and separated into two horizontal support bars 41 (if there is a support 5, first remove the cross bar 4 from the slot 51 of the support 5 out), the foldable cross strut groups 3 are passed between each table leg 11 to release the positioning function of the movable connecting seat 13, and each table leg 11 is retracted inward; each group of cross strut groups 3 is concentrated inward When the table legs 11 are retracted, the two horizontal struts 41 can be directly rotated and folded downward, so that the entire table frame 1 can be retracted to the minimum volume, as shown in Figure 7. On the contrary, when you want to use the folding table, unfold each table leg 11, connect and position the two horizontal support rods 41, if a support member 5 is provided, clamp the horizontal bar on the support member 5, and then unfold the table board 2 and then stand it. It can be placed between two horizontal bars 4.

As shown in FIG. 10 and FIG. 11 , it is another embodiment of the present invention. The difference between this embodiment and the previous embodiment is that three sets of cross strut sets 3 are provided between the two table legs 11 on each longitudinal side. , Correspondingly, the upper connection point located above the intersection connection of two adjacent cross strut groups 3 can each be provided with a support member 5 . By forming three sets of cross strut groups 3 in the length direction, the long side of the table frame can be made longer and the packaging size can be shorter.

After adopting the above structure, the present invention can have the following advantages compared with the existing technology:

(1) Set the crossbar supporting the table on the table legs and stagger it with the cross strut group. The two horizontal struts of the crossbar do not conflict with the cross strut group. When the table legs are retracted, the two horizontal struts are directly The rod rotates downward to fold, and the cross rod folds as a whole when the table frame is folded. It is easy to operate, and the inward folding method does not require outward expansion of the space required for the folding action, and can be adapted to various use occasions;

(2) The two horizontal struts of the horizontal bar can be connected through a socket. An elastic rope is installed between the two horizontal struts. The inner ends of the two horizontal struts can be pulled by the elastic rope and automatically rise as the table frame is opened. When the two horizontal struts are turned up and folded downward, the ends of the two horizontal struts can always be brought together under the action of the elastic force of the elastic rope;

(3) The upper part of the intersection of the two cross strut groups in the longitudinal side is connected with a support piece. The support piece can support the cross bar and at the same time fix the cross strut group under the cross bar without shaking, making the table frame Good strength and more stable.

The above-mentioned embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
