Detailed ways

Fig. 1～Fig. 8 have shown a specific embodiment of this multifunctional foldable desk of adjustable angle of the present invention, and the same as traditional desk, this desk also comprises desktop board 1 and is supported under this desktop board. There are four table legs 2, and the four table legs 2 are distributed in a rectangular shape.

The key improvement of this embodiment is that the desktop board 1 is composed of an upper board body 101 and a lower board body 102 whose rear sides are hinged together through two hinges. One end of the support rod 3 is hinged, and the top front side of the lower plate body 102 is provided with several slots 4 arranged at intervals along the length direction of the front side of the lower plate body. Both the upper plate body 101 and the lower plate body 102 are rectangular plates.

During use, if it is necessary to adjust the inclination angle of the desktop (for example, to facilitate reading), open the upper plate body 101 upwards, pull down the two support rods 3, and snap the other end of the support rods 3 into the corresponding card slot 4 , that is, the upper plate body 101 can be fixed at a desired angular position.

The second key improvement point of this embodiment is that the table leg 2 is composed of a lower leg rod 202 with an axial insertion hole and an upper leg rod 201 movably inserted in the axial insertion hole of the lower leg rod. segment telescopic structure, the upper leg bar 201 is turned over and connected to the bottom of the lower plate body 102 through the hinge 5, and the hinge 5 is provided with a According to the structure of the angular position of the body 102, the upper leg bar 201 and the lower leg bar 202 are provided with telescopic length positioning mechanisms for fixing the telescopic lengths of the two.

After the table leg 2 adopts the above-mentioned structure, the adjustment of the height of the desktop can be facilitated, and the length of the table leg 2 can be shortened and then close to the bottom of the table top plate 1.

In this embodiment, the specific structure of the telescopic length positioning mechanism is as follows: it includes several positioning holes 201a opened on the upper leg bar 201 and distributed up and down along the length direction of the upper leg bar, connected to the lower leg The movable tab 202a on the rod 202 and matched with the positioning hole 201a.

In this example, the outer contours of the upper leg bar 201 and the lower leg bar 202 are both square. In order to prevent the relative rotation of the two, the locking fit between the tongue 202a and the positioning hole 201a will be affected. In actual application, the tabs 202a are correspondingly snapped into the corresponding positioning holes 201a to obtain the required length of the table legs.

Referring to Fig. 4 and Fig. 5, in this embodiment, the specific structure of the hinge 5 is as follows: it consists of a hinge seat 501 fixedly connected to the bottom of the lower plate body 102 and a hinge seat 501 fixedly connected to the top of the upper leg rod 201 The hinge shaft 502 is formed, and the hinge shaft 502 and the upper leg rod 201 can be a separate assembly structure, and can also be an integral structure. The hinge base 501 is formed with a circular hole 501a with a horizontal axis, the hinge shaft 502 is rotatably connected horizontally in the circular hole 501a, and the inner wall of the top of the circular hole 501a is provided with a vertically upwardly extending limiting groove 501b , the axial ends of the hinge shaft 502 are provided with limiting ribs 502a corresponding to the limiting grooves 501b. The limiting groove 501b and the limiting rib 502a jointly form the above-mentioned "structure for fixing the upper leg bar 201 at an angular position perpendicular to the lower plate body 102".

When the folding table is in the unfolded state, the limiting rib 502a on the hinge shaft 502 is in a vertical state and snapped into the limiting groove 501b of the hinge base 501, thereby preventing the hinge shaft 502 from rotating relative to the hinge base 501, so that The table legs 2 are fixed in the vertical standing state shown in Fig. 1 . If the folding table needs to be folded up, the table leg 2 is pulled down to make the limiting rib 502a break away from the limiting groove 501b, and then the table leg 2 is turned to make it turn over and lean against the bottom of the table top 1 .

The third major improvement of the folding table in this embodiment is that it also includes two spring telescopic rods 6 arranged in parallel below the lower plate body 102 , one left and one right parallel, and the spring telescopic rods 6 are formed by the bobbin 602 , two connecting rods 601 respectively movably inserted inside the two ends of the copper tube, and a spring arranged inside the bobbin and connected between the two connecting rods, the outer ends of the two connecting rods 601 Both are respectively hinged to the lower plate body 102 through a movable suspender 8, and a horizontally arranged drawer plate 7 is fixedly connected between the tubes 602 of the two spring telescopic rods 6 .

In actual application, when the table needs to be folded, it is only necessary to push the drawer plate 7 up and adjust the position of the lower end of the movable suspension rod 8 properly so that the two connecting rods 601 are completely retracted into the inside of the bobbin 602, and at the same time the movable suspension The rod 8 also extends inside the bobbin 602 (the spring is compressed and shortened). The drawer board 7 is close to the bottom of the desktop board 1, and the table is fully folded, as shown in Fig. 4 and Fig. 8 . If the table needs to be unfolded, the drawer plate 7 is pulled downward, and under the joint action of the pulling force and the spring force, the two connecting rods 601 stretch out to the limit position, and the movable suspension rod 8 is completely moved out to the outside of the bobbin 602 , the movable suspender 8 is in the vertical state shown in Fig. 1 and Fig. 5, and the drawer board 7 is separated from the desktop board 1 up and down to have a storage function.

In order to well cover the folded table legs 1, four desktop side shields 9 are arranged around the lower body of the desktop in this example.

Referring to Figure 8, among the four table legs, the upper leg rods 201 of two of the diagonally positioned table legs are reversibly connected to the lower plate body 102, and the other two are in the The upper leg bar 201 of the table leg at the diagonal position is connected to the lower plate body 102 in a turnable left-right manner. Such setting can make the table in the folded state, and the four table legs 1 are all in the same thickness layer, so as to further reduce the folded body shape of the folding table.

Certainly, the above-mentioned embodiments are only for illustrating the technical conception and characteristics of the present invention, and the purpose is to enable people to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present invention shall fall within the protection scope of the present invention.
