Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

example 1, as shown in fig. 1, 2, 10, 11;

the desk with the expansion function comprises a drawer 4, a connecting plate 5, an upright post 6 and a base 7, wherein the lower end of the drawer 4 is connected with the upper end of the upright post 6 through the connecting plate 5, and the lower end of the upright post 6 is connected with the base 7;

the desk still includes:

an expanding device 1 for expanding a placing space to the front upper part of the desk;

a bookshelf 2 for expanding a placing space to the front lower part of the desk;

the pen container 3 is arranged on the side plate 42 of the drawer 4.

In this embodiment, two connecting plates 5 are generally fixedly mounted at the lower ends of two sides of the drawer 4, respectively, a plurality of through holes are vertically arranged on the connecting plates 5, a plurality of through holes are also vertically arranged at the upper ends of the columns 6, at least two through holes on the connecting plates 5 and at least two through holes on the columns 6 are aligned with each other, and screws 51 are passed through the through holes for locking, so that the connecting plates 5 and the columns 6 are fixed; the upright 6 and the base 7 may be integrally formed, and the upright 6 may be perpendicular to the base 7.

Example 2, as shown in fig. 1, 2, 10, 12;

this example differs from example 1 in that: the expanding device 1 comprises a first bearing plate 11 and a first handle 12, a fourth sliding groove 423 is transversely arranged on a side plate 42 of the drawer 4, a first sliding groove 411 is transversely arranged on an upper panel of the drawer 4, the first sliding groove 411 is communicated with the fourth sliding groove 423, one side end of the first handle 12 is connected with one side end of the first bearing plate 11, the first handle 12 slides in the fourth sliding groove 423, the first bearing plate 11 slides in the first sliding groove 411, and when the first bearing plate 11 does not extend out of the drawer 4, the rearmost end of the first handle 12 in the fourth sliding groove 423 is arranged.

In this embodiment, the width of the first handle 12 is larger than the depth of the fourth sliding groove 423, so that the first handle can be conveniently moved by hand.

When the embodiment works, the first supporting board 11 is generally completely retracted into the first sliding slot 411 for hiding; when the desk needs to be used, the first handle 12 is pushed forward, the first bearing plate 11 is pushed out along the first sliding groove 411, the first bearing plate 11 is lower than the desktop of the desk, and the use of placing an electronic product such as a notebook computer 8 is not affected.

Example 3;

this example differs from example 1 or 2 in that: the length, width and height of the first bearing plate 11 are correspondingly slightly smaller than those of the first sliding slot 411. Such a design prevents the first supporting plate 11 from shaking greatly when sliding in the first sliding slot 411, and also prevents the first supporting plate 11 from tilting downward when fully extending.

Example 4, as shown in FIGS. 1-8, 11;

this example differs from example 1 in that: the bookshelf 2 includes:

a slide plate 22; a second sliding groove 421 is vertically arranged in the front panel 41 of the drawer 4, and the lower end and one side of the second sliding groove 421 are open; the sliding plate 22 is slidably mounted in the second chute 421;

a second handle 21; the second handle 21 is fixedly connected to the upper end of one side of the sliding plate 22, and the second handle 21 slides in the open part of one side of the second sliding chute 421;

two fixed blocks 23; the lower end of the sliding plate 22 is connected with two fixed blocks 23, and the sliding plate 22 is vertical to the fixed blocks 23;

a connecting block 25; two ends of the connecting block 25 are respectively fixed with the inner sides of the two fixing blocks 23;

two bearings 27; the outer rings of the two bearings 27 are respectively arranged on the two fixed blocks 23; the bearing 27 adopts a damping bearing 27, so that the situation that the second bearing plate 24 is easily turned downwards when being folded is avoided;

a rotating shaft 26; two ends of the rotating shaft 26 are respectively fixedly connected with the inner rings of the two bearings 27;

a second carrier plate 24; the first end of the second bearing plate 24 is fixed with the rotating shaft 26, the first end of the second bearing plate 24 rotates between the two fixing blocks 23, the rotating angle of the second bearing plate 24 is 90 degrees, and when the second bearing plate 24 rotates to be horizontal, the top surface of the first end of the second bearing plate 24 abuts against the connecting block 25.

The sliding plate 22 and the desk have friction force action, and the friction force action is larger than the integral gravity of the bracket, so that the sliding plate 22 cannot slide downwards when not pushed by hands;

when the embodiment works, firstly, the sliding plate 22 is completely retracted into the second sliding groove 421, and the second bearing plate 24 is vertically arranged, so that the bookshelf 2 does not occupy space;

then, the second handle 21 is pushed downward to drive the sliding plate 22 to move downward, and when the sliding plate moves downward to the limit, the second bearing plate 24 is unfolded to keep the second bearing plate 24 and the sliding plate 22 in a vertical state, and at this time, a large number of unused books 9 can be placed on the second bearing plate 24.

Example 5, as shown in fig. 9;

this example differs from example 1 in that: the pen container 3 is formed into a square barrel type structure, the pen container 3 is vertically arranged, the upper and lower parts of two opposite side walls of the pen container 3 are respectively provided with a baffle 31, a side plate 42 of the drawer 4 is provided with a third sliding groove 422, the third sliding groove 422 is communicated with the inner space of the drawer 4, the pen container 3 transversely slides in the third sliding groove 422, and the baffle 31 is used for blocking the pen container 3 to avoid completely separating from the third sliding groove 422.

When the embodiment is in use and is in a non-use state, the pen container 3 can retract into the inner space of the drawer 4 along the third sliding groove 422 to be hidden, and the blocking of the baffle plate 31 cannot be separated; when the drawer is used, the drawer is pushed out from the inside of the drawer 4 along the third sliding groove 422, and the drawer is placed outside the drawer 4, so that the drawer can be filled with articles for use.

In the present application, the distribution of the gravity centers of the desk should be ensured, and even when a relatively large number of heavy objects are placed on the first bearing plate 11 and the second bearing plate 24, the desk still needs to be kept from tipping over; in particular, the upright 6 and the base 7 can be given a greater weight.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
