Description

Technical Field

[0001] The utility model relates to the technical field of dining tables, in particular to an outdoor foldable portable dining table. Background Art

[0002] With the development of society, more and more people like outdoor camping. Camping is a short-term outdoor lifestyle. Generally, it is necessary to carry some daily necessities to meet the short-term life needs. The items carried are mostly light and portable. Outdoor picnics are an important part of it. Outdoor picnics inevitably require the use of dining tables. In order to ensure the strength of the tabletop, existing outdoor dining tables are generally made of wooden boards, and the boards are relatively thick and heavy, which is not easy to move. The thinner wooden tabletop has poor load-bearing capacity. Therefore, many outdoor dining tables are bulky and take up a large space, which is not easy to store and carry.

[0003] After searching, Chinese Patent Publication (Announcement) No. 202222963286.6 discloses an outdoor folding portable dining table. The patent has a table top made of a metal plate and the periphery of the table top is bent downward to form a side panel. The side panel is perpendicular to the upper side of the table top, and an edging strip is provided on the outer side of the side panel to form a fold. Although the above patent has a foldable function, the folding method is too cumbersome, and the supporting legs need to be folded or flipped in turn, which makes the operation inconvenient. In addition, the current dining table does not have the function of expanding the leg support area when extended. Therefore, it is necessary to design an outdoor folding portable dining table.

[0025] In this embodiment, there are two slide grooves 5 and they are symmetrically arranged. A slider 6 is slidably connected inside the slide groove 5. The slider 6 is threadedly connected to the screw rod 4. One side of the slider 6 is rotatably connected to a push rod 7. The push rod 7 is rotatably connected to the desktop side panel 3. A handle 16 is fixedly connected to one side of the outer surface of the support tube 1.

[0026] When the dining table needs to be unfolded, the screw rod 4 only needs to be rotated forward. Through the threaded effect of the screw rod 4 and the slider 6, the slider 6 can slide in the slide groove 5, so that the screw rod 4 rotates and drives the slider 6 to move upward, and the push rod 7 is pushed to make the table top side panels 3 on both sides flip to a horizontal angle. The table top side panels 3 are flipped to a horizontal angle to complete the unfolding and use. After folding, it is convenient to lift and move through the handle 16, which has a portable function.

[0027] In this embodiment, a notch 8 is formed on one side of the outer surface of the support tube 1 close to the bottom end, and a worm gear 9 is fixedly connected to one side of the outer surface of the screw rod 4 close to the bottom end.

[0028] When in use, the worm wheel 9 is fixed to the bottom of the screw rod 4, and the worm wheel 9 can drive the screw rod 4 to rotate after being rotated by the force.

[0029] In this embodiment, a vertical plate is fixedly connected to one side of the outer surface of the support tube 1 , a worm 10 is rotatably connected to one side of the vertical plate, and the worm 10 is meshingly connected to the worm wheel 9 .

[0030] During specific use, the meshing effect between the worm 10 and the worm wheel 9 is utilized, and the worm 10 can be rotated to drive the worm wheel 9 to rotate, so that the lead screw 4 can be rotated for easy adjustment.

[0031] In this embodiment, a bottom cylinder 11 is fixedly connected to the lower surface of the support cylinder 1 , the screw rod 4 is rotationally connected to the bottom cylinder 11 , and a pinion 12 is fixedly connected to the bottom end of the screw rod 4 .

[0032] When in use, the screw rod 4 rotates to drive the small gear 12 to rotate, and after the rotation, the difference in the number of turns between the small gear 12 and the small gear 12 is used to reduce the rotation speed of the large gear 13.

[0033] In this embodiment, a large gear 13 is rotatably connected to the inner top wall of the bottom tube 11 , and the large gear 13 is meshingly connected with the small gear 12 . There are three large gears 13 .

[0034] When in use, the pinion 12 rotates, and the small gear 12 drives the large gear 13 to rotate through the meshing effect of the small gear 12 and the large gear 13.

[0035] In this embodiment, a stretching rod 14 is slidably connected to one side of the outer surface of the bottom tube 11 , and one end of the stretching rod 14 penetrates the outer surface of the bottom tube 11 and extends to the inside of the bottom tube 11 .

[0036] During specific use, the sliding effect between the tube extension rod 14 and the bottom tube 11 enables the extension rod 14 to have the functions of extension and contraction, and can increase the contact area with the ground after being extended.

[0037] In this embodiment, an arc groove 15 is formed on the lower surface of the large gear 13 , and the arc groove 15 is slidably connected to one end of the stretching rod 14 .

[0038] When in use, the stretching rod 14 and the arc groove 15 slide together, and the stretching rod 14 and the bottom tube 11 can slide, so that the large gear 13 rotates to stretch the stretching rod 14, and reverses to retract it.

[0039] Working principle: During use, when the dining table needs to be unfolded, it is only necessary to rotate the screw rod 4 forward. Through the threaded effect of the screw rod 4 and the slider 6, and the slider 6 can slide in the slide groove 5, so that the screw rod 4 rotates and drives the slider 6 to move upward, and the push rod 7 is pushed to make the table top side panels 3 on both sides flip to a horizontal angle. The table top side panels 3 are flipped to a horizontal angle to complete the unfolding and use. After use, the screw rod 4 is rotated in the opposite direction to drive the slider 6 to move downward, so that the push rod 7 pulls the table top side panels 3 to flip downward, and the folding and extension are completed. The operation is convenient. When the screw rod 4 is rotated forward to unfold the table top, at this time The small gear 12 rotates, and the meshing effect of the small gear 12 and the large gear 13 makes the small gear 12 drive the large gear 13 to rotate. Through the sliding effect of the extension rod 14 and the arc groove 15, the large gear 13 rotates to extend the extension rod 14. The three groups of extension rods 14 are used to increase the contact area with the ground, making the dining table more stable. The difference in the number of turns between the two is used to reduce the rotation speed of the large gear 13, which is convenient for the screw rod 4 to rotate so that the table top and the bottom are unfolded at the same time. After use, the screw rod 4 is rotated in the opposite direction to reverse the large gear 13, so that the extension rod 14 can be retracted inward to complete the folding.
