Detailed ways

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to FIGS. 1 to 14 . The structural contents mentioned in the following embodiments are all referenced to the accompanying drawings.

Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

The portable assembly table is characterized in that it includes a first table board 1 and a second table board 2 that are rotated and installed. The table board 3, the fourth table board 4, the third table board 3 and the fourth table board 4 are rotated and installed, the first table board 1, the second table board 2, the third table board 3, the fourth table board 4 There is a first groove 5 based on ergonomic design and the bottom wall is respectively provided with a slideway 6, a distance adjusting device is arranged in the slideway 6, and two mutually hinged support legs 7 are rotated and installed on the distance adjusting device, The distance adjustment device can adjust the size of the expansion range of the two supporting legs 7 that cooperate with each other, thereby realizing the adjustment of the height of the table board. A U-shaped frame 9 is slidably connected to the length direction of the support leg 7, and a one-way gear 10 meshing with the rack 8 is installed on the U-shaped frame 9 in rotation. , the U-shaped frame 9 is perpendicular to the two cantilever parts and is threadedly fitted with an adjusting bolt 12 that is rotatably mounted on the outer wall of the support leg 7, and the bottom of the support leg 7 and the rack 8 are fitted with positioning bolts 13 through threads and the positioning bolts 13 One end of the inner end of the support leg 7 is in contact with the side wall of the rack 8 .

When this embodiment is in use, referring to Figures 12 and 13, in the initial state, the two table boards that are rotated and installed with each other are in a folded state, and the support leg 7 at the bottom of the table board is also in a folded state, and at this time it is in a folded state. The table board and support legs 7 in the folded and folded state are easy to carry, and can be easily moved to any required place for use; when the assembled table needs to be used, we will rotate and install the first table board 1 and The second table board 2 is unfolded, and the third table board 3 and the fourth table board 4 which are rotated and installed are unfolded, and the passage between the first table board 1 and the third table board 3, the second table board 2 and the fourth table board The plates 4 are fixedly connected by the first connecting pin 24. We are provided with a slideway 6 on the bottom wall of the table plate and a distance adjusting device is arranged in the slide. Two mutually hinged support legs 7 are rotated and installed on the distance adjusting device. The distance between the two mutually hinged support legs 7 is adjusted by the distance adjusting device, so that the two mutually hinged support legs 7 are unfolded, and then the assembled table board is supported by the unfolded support legs 7. The adjusting device can adjust the distance between the two mutually hinged support legs 7, so as to control the magnitude of the expansion of the two support legs 7, and then control the height of the table board from the ground, so that the height of the assembled table table board from the ground can be adjusted. , when used together with chairs, it can be applied to chairs of different heights, and the height of the table can also be adjusted according to the height of the participants, making the assembled table more applicable;

We are provided with a sliding hole extending along the length direction of the supporting leg 7 at the bottom of the supporting leg 7 and the rack 8 is slidably connected in the sliding hole. After we assemble the table board and unfold the supporting leg 7, if one or more The height of each support leg 7 is different from the ground contact position, then the support leg 7 at the lower part of the terrain will be in a suspended state. Referring to Figure 3, at this time, we screw the positioning bolt on the support leg 7 by screwing 13. Release the positioning of the rack 8 by the positioning bolt 13 (when the positioning bolt 13 is screwed into the support leg 7 and abuts against the side wall of the rack 8, the rack 8 is positioned) so that it is slidably connected to the support leg 7 The rack 8 at the bottom slides down along the support leg 7 and drives the one-way gear 10 that meshes with it to rotate. The rack 8 slides down along the support leg 7 until the bottom of the rack 8 touches the ground, and no longer slides down , since the rack 8 is placed on the outer end of the support leg 7 and the bottom plate 11 is rotated and installed, the support leg 7 is placed on the ground smoothly through the bottom plate 11. Due to the special nature of the one-way gear 10, the rack 8 can only continue to Sliding down along the previous lowering, can not slide up in the opposite direction, then the rack 8 is firmly positioned at this position. If the other supporting legs 7 are also in the suspended state, the adjustment can also be achieved through the above process. The bottoms of the supporting legs 7 can be more firmly and stably contacted with the ground, so that the assembled table board can be placed more stably. If the supporting legs 7 need to be processed and folded, referring to Figure 4, we first twist and adjust the The bolts 12 drive the U-shaped frame 9 to slide in a direction perpendicular to the length of the support legs 7 (we are provided with matching sliders and sliding grooves on the side walls of the support legs 7 and the inner side of the cantilever of the U-shaped frame 9), and then drive the one-way gear 10 and the teeth. The strip 8 is disengaged. Preferably, we have a rectangular sliding hole 34 on the side wall of the support leg 7 that fits the one-way gear 10 to slide with the U-shaped frame 9. When the one-way gear 10 is disengaged from the rack 8, we will remove the rack 8 slide into the support leg 7, at this time, reversely rotate the adjusting bolt 12 to re-engage the one-way gear 10 with the rack 8 again, and then screw the positioning bolt 13 so that one end of the positioning bolt 13 placed in the support leg 7 abuts against the rack 8. The positioning of the rack 8 is realized on the side wall of the rack 8 .
