Technical Field

[0001] This application relates to the technical field of outdoor supplies, and particularly relates to a support table leg and a camping table. Background Art

[0002] With the continuous improvement of people's living standards, more and more people like to go for an outing. When going for an outing, many people like to have a picnic, so an outdoor folding table that can place food and some utensils is needed. A folding table is a table designed to save space and be easy to carry. Its main feature is that the table legs and the tabletop can be folded, so that the table can be easily stored or transported when not in use.

[0003] Most of the table legs of existing folding tables adopt a flip structure. The table legs can rotate between an unfolded position and a folded position. When the folding table is unfolded for use, the table legs rotate to the unfolded position to support the tabletop. When the folding table is folded for storage, the table legs rotate to the folded position to fit with the tabletop. However, the table legs with a flip structure need to be provided with a limiting structure to limit the rotation of the table legs to prevent the folding table from tipping over due to the relative rotation of the table legs and the tabletop during use. Summary of the Invention

[0008] As another preference, two first tenons are arranged on the outer side wall of the central axis, and the two first tenons are symmetrically arranged along the axis of the central axis at the top end of the central axis far from the first joint end face; two second tenons are arranged on the inner wall of the connecting seat, and the two second tenons are symmetrically arranged along the axis of the connecting seat, and an insertion opening for the central axis and the first tenon to pass through is formed between the two second tenons, and the shape of the insertion opening is adapted to the shapes of the central axis and the first tenon.

[0009] Further preferably, the connecting seat is obliquely arranged on the mounting plate. After the support pipe fitting is rotationally engaged with the mounting plate, an included angle is formed between the support pipe fitting and both the length direction and the width direction of the mounting plate.

[0010] Furthermore, a limiting boss is further arranged on the inner wall of the connecting seat far from the opening, and the limiting boss is adapted to limit the maximum rotation angle of the clamping member.

[0011] Furthermore, two limiting bosses are arranged on the inner wall of the connecting seat, and the two limiting bosses are symmetrically arranged along the axis of the connecting seat, and the two limiting bosses are respectively arranged on the limiting end faces of the two second tenons, and the limiting bosses are adapted to abut against the side end faces of the first tenons to limit the maximum rotation angle of the clamping member.

[0012] Furthermore, each second tenon includes an opposite first end and a second end, and the limiting boss is arranged at the first end of one second tenon, and the other limiting boss is arranged at the second end of the other second tenon, so that when the clamping member rotates to the maximum rotation position, the included angle between the connection line of the two first tenons and the insertion opening is 90°.

[0013] Furthermore, the support pipe fitting includes an outer pipe and an inner pipe, the inner pipe is slidably sleeved inside the outer pipe, and a locking member is arranged between the outer pipe and the inner pipe, and the locking member is adapted to limit the relative sliding of the inner pipe with respect to the outer pipe.

When the user installs or disassembles the support pipe fitting, it is only necessary to rotate the support pipe fitting along its own axis by no more than half a turn, which greatly simplifies the installation and disassembly operations of the support pipe fitting, shortens the assembly and disassembly time of the camping table, and improves the convenience of use of the camping table;

[0018] (2) In the support table leg provided by the present application, a limiting boss is further provided on the inner wall of the connection seat. The limiting boss is adapted to limit the maximum rotation angle of the clamping member to 90°, thereby improving the stability after the rotational engagement of the clamping member and the connection seat. In addition, the connection seat is inclined on the mounting plate. When the support pipe fitting is rotationally engaged on the mounting plate, the support pipe fitting extends obliquely, forming an angle with both the length direction and the width direction of the mounting plate. Furthermore, when the support table legs are arranged at the four corners of the tabletop, the camping table as a whole is in the shape of a quadrangular frustum, so that the camping table has good structural stability and is not easily overturned during use.

Detailed implementation manners

[0032] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0033] In the description of the present application, it should be noted that for the orientation terms, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationship are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0035] The terms "comprising" and "having" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0036] As Figures 1-10 shown, this application provides a support table leg, which includes a support pipe fitting 100 and a mounting plate 200 for connecting with a tabletop 300. A clamping member 110 is provided at the end of the support pipe fitting 100 where it is connected to the mounting plate 200, and a connecting seat 210 that cooperates with the clamping member 110 is provided on the mounting plate 200. The clamping member 110 is adapted to rotatably engage with the connecting seat 210 so that the support pipe fitting 100 can be detachably connected to the mounting plate 200.

[0037] Most of the table legs of existing camping tables are connected by means of threaded connection. Users need to turn the table legs a relatively large number of turns to install the table legs onto the tabletop 300 of the camping table or remove the table legs from the tabletop 300 of the camping table. The operations of installing and removing the table legs are rather cumbersome and take a relatively long time. The support table leg provided by this application realizes the connection between the support pipe fitting 100 and the mounting plate 200 through the rotatable engagement of the clamping member 110 and the connecting seat 210. When the user installs or removes the support pipe fitting 100, it is only necessary to rotate the support pipe fitting 100 along its own axis by no more than half a turn, which greatly simplifies the operations of installing and removing the support pipe fitting 100, shortens the time for assembling and disassembling the camping table, and improves the convenience of use of the camping table.

[0038] Furthermore, as Figures 2-5As shown, the clamping member 110 includes a first engaging end face 111 and a protruding end face 112 that perpendicularly protrudes outward from the first engaging end face 111. The first engaging end face 111 and the protruding end face 112 are planar structures. A central shaft 113 extending toward the connecting seat 210 along the axis of the support pipe fitting 100 is provided on the protruding end face 112. One or more first tenons 114 are provided on the outer sidewall of the central shaft 113; the connecting seat 210 includes a second engaging end face 211. An opening 212 is provided on the second engaging end face 211. One or more second tenons 213 are provided on the inner wall of the connecting seat 210 near the opening 212. The end face of the second tenon 213 near the opening 212 is a guiding end face 2131, and the end face of the second tenon 213 far from the opening 212 is a limiting end face 2132. The second engaging end face 211, the guiding end face 2131, and the limiting end face 2132 are all planar structures. When the clamping member 110 is rotationally engaged with the connecting seat 210, the first tenon 114 is located on the side of the second tenon 213 far from the opening 212, that is, the first tenon 114 abuts against the limiting end face 2132 of the second tenon 213. The second engaging end face 211 and the guiding end face 2131 are respectively adapted to closely fit with the first engaging end face 111 and the protruding end face 112. The mutual abutment of the first tenon 114 and the second tenon 213 restricts the separation of the clamping member 110 from the connecting seat 210.

[0039] Specifically, in the illustrated embodiment, two first tenons 114 are provided on the outer wall of the central shaft 113. The two first tenons 114 are symmetrically arranged along the axis of the central shaft 113 at the top end of the central shaft 113 away from the first joint end face 111, and the top end face of the first tenon 114 is flush with the top end face of the central shaft 113. Two second tenons 213 are provided on the inner wall of the connecting seat 210. The two second tenons 213 are symmetrically arranged along the axis of the connecting seat 210, and an insertion opening 214 for the central shaft 113 and the first tenon 114 to pass through is formed between the two second tenons 213. The shape of the insertion opening 214 is adapted to the shapes of the central shaft 113 and the first tenon 114. After the central shaft 113 and the first tenon 114 on the clamping member 110 pass through the insertion opening 214, the support pipe fitting 100 can rotate 90° relative to the connecting seat 210 along its own axis, so that the first tenon 114 is arranged in a dislocation manner with the insertion opening 214. The first tenon 114 and the second tenon 213 cooperate with each other, and the bottom end face of the first tenon 114 abuts against the limiting end face 2132 of the second tenon 213, thereby restricting the detachment of the clamping member 110 from the connecting seat 210 and realizing the fitting connection between the support pipe fitting 100 and the mounting plate 200. When the support pipe fitting 100 wants to be disassembled from the mounting plate 200, it only needs to rotate the support pipe fitting 100 90° in the opposite direction along its own axis. The first tenon 114 and the central shaft 113 can exit the connecting seat 210 from the insertion opening 214 between the two second tenons 213. After the support pipe fitting 100 is disassembled from the mounting plate 200, the dimension of the camping table in the height direction is reduced, and the space required by the camping table is also correspondingly reduced, thus facilitating the user to store or carry the camping table.

[0040] In some preferred embodiments, as Figure 10 shown, the connecting seat 210 is inclined on the mounting plate 200, so that after the support pipe fitting 100 is connected to the mounting plate 200, the support pipe fitting 100 is also inclined on the mounting plate 200, and an included angle is formed between the length direction of the support pipe fitting 100 and the mounting plate 200 and the width direction of the mounting plate 200. Based on the above structure, when the support table legs are installed at the four corners of the camping table top, the camping table as a whole is in the shape of a quadrangular frustum. Whether on the front or side of the camping table, the support pipe fitting 100 forms a trapezoidal structure with the table top 300, thereby ensuring the stability and structural strength of the camping table when placed.

[0041] Furthermore, a limiting boss 215 is also provided on the inner wall of the connecting seat 210. The limiting boss 215 is adapted to limit the rotation angle of the clamping member 110 to prevent the rotation angle of the clamping member 110 from being too large or too small, resulting in the easy detachment of the clamping member 110 from the inside of the connecting seat 210. Specifically, as Figures 2-3 and Figures 7-9As shown, two limiting bosses 215 are provided on the inner wall of the connecting seat 210. The two limiting bosses 215 are respectively connected to the limiting end faces 2132 of the two second tenons 213. The two second tenons 213 both include opposite first ends and second ends. One of the limiting bosses 215 is arranged at the first end of one second tenon 213, and the other limiting boss 215 is arranged at the second end of the other second tenon 213. When the clamping member 110 rotates to the maximum rotation position where the side end face of the first tenon 114 abuts against the limiting boss 215, the included angle α between the line L connecting the two first tenons 114 of the clamping member 110 and the insertion port 214 is 90°. That is to say, at this time, the projections of the two first tenons 114 and the central axis 113 on the horizontal plane and the projection of the insertion port 214 on the horizontal plane are perpendicular to each other to form a cross structure. Furthermore, the limiting boss 215 limits the maximum rotation angle of the clamping member 110 to 90°. The arrangement that the line L connecting the two first tenons 114 of the clamping member 110 and the insertion port 214 is at 90° can ensure the reliability after the clamping member 110 and the connecting seat 210 are rotationally engaged.

[0042] As Figure 2 and Figure 12 shown, at least one pipe fitting slot 220 for installing and supporting the pipe fitting 100 is further provided on the mounting plate 200. The pipe fitting slot 220 is in a superior arc shape, and the superior arc is an arc with a radian greater than a semi-circle. That is to say, the radian of the pipe fitting slot 220 is greater than a semi-circle. The slot diameter of the pipe fitting slot 220 is adapted to the pipe diameter of the supporting pipe fitting 100, so that the supporting pipe fitting 100 separated from the connecting seat 210 can be firmly embedded in the pipe fitting slot 220 to prevent the supporting pipe fitting 100 from being lost due to being placed separately from the mounting plate 200. It is worth mentioning that the pipe fitting slot 220 extends in the horizontal direction, so that when the supporting pipe fitting 100 is clamped in the pipe fitting slot 220, the supporting pipe fitting 100 is arranged parallel to the table board 300. Generally, the pipe fitting slot 220 can be implemented to extend along the length direction of the table board 300 or along the width direction of the table board 300 according to the length of the supporting pipe fitting 100 and the size of the table board 300.

[0043] Of course, as Figure 6As shown, the support pipe fitting 100 can also be implemented as a telescopic pipe structure. That is, the support pipe fitting 100 includes an outer pipe 130 and an inner pipe 120. The inner pipe 120 is movably sleeved inside the outer pipe 130. A locking member 140 is provided between the outer appearance and the inner pipe 120. The locking member 140 includes a connecting end portion 141 and a positioning end portion 142. The end of the positioning end portion 142 is hemispherical. The connecting end portion 141 of the locking member 140 is arranged inside the inner pipe 120. The positioning end portion 142 of the locking member 140 passes through the first positioning hole 121 on the pipe wall of the inner pipe 120 and extends to the outside of the inner pipe 120. An elastic member is provided between the connecting end portion 141 and the pipe wall of the inner pipe 120. The elastic member is adapted to push the positioning end portion 142 outward in a direction perpendicular to the pipe wall of the inner pipe 120. A second positioning hole 131 for cooperating with the positioning end portion 142 is provided on the outer pipe 130. When the support pipe fitting 100 extends, the inner pipe 120 slides relative to the outer pipe 130 to a position where the second positioning hole 131 is aligned with the positioning end portion 142. The positioning end portion 142 cooperates with the second positioning hole 131 under the pushing of the elastic member, thereby restricting the relative sliding between the outer pipe 130 and the inner pipe 120. When the support pipe fitting 100 wants to be retracted, the positioning end portion 142 can be pressed so that the positioning end portion 142 is separated from the positioning hole, and the inner pipe 120 can slide relative to the outer appearance to shorten the overall length of the support pipe fitting 100. A plurality of second positioning holes 131 can be arranged along the axial direction of the outer pipe 130, so that the ball can cooperate with different second positioning holes 131 to realize the gear adjustment of the length of the support pipe fitting 100.

[0044] In some preferred embodiments, the installation plate 200, the pipe fitting slot 220, and the connecting seat 210 are all made of plastic. Furthermore, the pipe fitting slot 220 and the connecting seat 210 can be integrally injection-molded on the installation plate 200, thereby simplifying the processing technology of the installation plate 200, the pipe fitting slot 220, and the connecting seat 210. The plastic material itself has a certain elasticity. When the plastic part is subjected to an external force and stretched, the plastic part will undergo elastic deformation and generate a force. Specifically, when the support pipe fitting 100 is clamped in the pipe fitting slot 220, the pipe fitting slot 220 undergoes elastic deformation and generates a force acting on the support pipe fitting 100, so that when the external force does not exceed a preset value, the support pipe fitting 100 is limited in the pipe fitting slot 220, that is, the reliability of the clamping fit between the support pipe fitting 100 and the pipe fitting slot 220 can be ensured, and the support pipe fitting 100 can be prevented from disengaging from the pipe fitting slot 220 after being subjected to a slight external force.

[0045] Based on the above support table legs, as Figures 11-12 shown, the present application also provides a camping table, which includes the above support table legs, and includes a table board 300 and support table legs arranged on the table board 300. The installation plate 200 is fixed on the table board 300 by bolts, and the support pipe fitting 100 is rotationally clamped on the connecting seat 210.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present application.
