Utility model content

Aiming at the above-mentioned deficiencies in the prior art, the utility model provides a bench with the function of retracting the desktop, which solves the problems of single function and small use space of the existing bench.

In order to achieve the above-mentioned purpose of the invention, the technical scheme that the utility model adopts is:

Provided is a bench with the function of retracting the desktop, which includes a first panel, first grooves are provided on both sides of the upper surface of the first panel; brackets are hinged in the first grooves; the end of the bracket is hinged to the second panel ; Both sides of the lower surface of the second panel are provided with second grooves; telescopic rods are hinged in the second grooves; at least two groups of stool legs are arranged on the lower surface of the first panel, and the stool located below the hinged end of the telescopic rods The outer sides of the legs are all provided with concave cavities; the other end of the telescopic rod ends in the concave cavity.

The beneficial effects of the utility model are: the second panel used as the desktop is stored on the first panel used as the bench, which saves the space occupied by the bench when the second panel is not used; when the bench needs to be used for studying or storing things , the second panel can be extended obliquely upwards to form a tabletop, and the telescopic rod cooperates with the bracket to support the second panel, expanding the usable space of the bench and improving the practicability of the bench.

Further, the stool legs are set in a U shape, and the bottoms of the stool legs are provided with fixing holes.

The beneficial effect of adopting the above-mentioned further solution is that the same group of stool legs are integrally formed to improve the stability of the stool legs, screws can be set in the fixing holes to fix the position of the bench, and prevent the center of gravity of the bench from shifting and toppling when the second panel is unfolded .

Further, the telescoping rod is provided with matching round holes and spring pins.

The beneficial effect of adopting the above further solution is: the matched round holes and spring pins provided on each stage of the telescopic rod can make the length of the telescopic rod fixed after stretching, and prevent the telescopic rod from being compressed and contracted by the force of the second panel , improve the stability of this bench.

Further, the first groove runs through the upper and lower ends of the first panel.

The beneficial effect of adopting the above further solution is that no dust or other garbage will be deposited in the first groove, which will affect the storage of the bracket.

Further, the rotation range of the bracket is 0°-120°.

The beneficial effect of adopting the above-mentioned further solution is that the second panel can be fully expanded by limiting the rotation range of the bracket to 120°, and the force required to be borne by the bracket can be reduced, and the durability of the bench can be improved.

Further, the length and width of the first panel and the length and width of the second panel are correspondingly equal.

The beneficial effect of adopting the above further solution is: when the second panel is stored on the first panel, the two panels can be overlapped, which further saves the occupied space.

Detailed ways

The specific embodiment of the present utility model is described below, so that those skilled in the art understand the utility model, but should be clear, the utility model is not limited to the scope of specific embodiment, for those of ordinary skill in the art, as long as Various changes are within the spirit and scope of the utility model defined and determined by the appended claims, and these changes are obvious, and all inventions and creations utilizing the concept of the utility model are all included in the protection list.

As shown in Fig. 1, Fig. 2 and Fig. 3, the bench with retractable desktop function includes a first panel 1, and both sides of the upper surface of the first panel 1 are provided with first grooves 11; two first grooves The rear ends in 11 are respectively hinged with brackets 4; the ends of the two brackets 4 are respectively hinged with the front ends of the second panel 2; both sides of the lower surface of the second panel 2 are provided with second grooves 22; the two second grooves The rear ends in 22 are respectively hinged with telescopic rods 5; the lower surface of the first panel 1 is provided with at least two groups of stool legs 3, and the outer sides of the rear row of stool legs 3 are provided with concave cavities; the ends of the telescopic rods 5 stop at the concave cavity cavity.

The extended length of the telescopic rod 5 is determined by the rotation of the support 4 to the maximum angle, and the end of the telescopic rod 5 is placed in the concave cavity of the stool leg 3, and the length of the second panel 2 is kept parallel to the first panel 1 .

In order to improve the stability of the stool legs 3, fix the position of the bench, and prevent the center of gravity of the bench from shifting and toppling when the second panel 2 is unfolded, the stool legs 3 are arranged in a U shape, and the bottom of the stool legs 3 is provided with a fixing hole 31, Screws can be arranged in the fixing holes 31, so that the stool legs 3 are fixed to the bottom surface.

As shown in Figure 4, in order to make the telescopic rod 5 fixed in length after stretching, avoid the telescopic rod 5 from being compressed and contracted by the second panel, and improve the stability of the bench, the telescopic rod 5 is provided with a matching Round hole 51 and spring pin. When the telescopic rod 5 is stretched, the spring pin is stuck in the circular hole 51 to keep the length of the telescopic rod 5 constant.

In order not to deposit dust or other rubbish in the first groove 11 and affect the storage of the bracket 4, the first groove 11 runs through the upper and lower ends of the first panel 1, and the length, width and height of the bracket 4 are smaller than the first groove The length, width and height of 11 allow the bracket 4 to be completely accommodated in the first groove 11 .

In order to fully expand the second panel 2, reduce the force that the support 4 needs to bear, and improve the durability of the bench, the rotation range of the support 4 is 0°-120°.

In order to allow the second panel 2 to be placed on the first panel 1, the two panels can be overlapped to further save the space occupied by the bench, the length and width of the first panel 1 and the length and width of the second panel 2 are respectively equal, and The contracted size of the telescopic rod 5 is smaller than the size of the second groove 22 , so that the telescopic rod 5 can be completely accommodated in the second groove 22 .

In the specific implementation process, the length of the bracket 4 is less than the length of the first groove 11, the first hinge hole 12 is arranged beside the first groove 11, a through hole is arranged at one end of the bracket 4, and the bracket 4 is inserted into the first hinge hole 12. It is hinged with the cylinder of its through hole; the same, the second groove 22 is also provided with a second hinged hole 21, and one end of the telescopic rod 5 is also provided with a through hole, and the telescopic rod 5 is inserted into the second hinged hole 21 and on it. The cylinder of the through hole is hinged so that the telescopic rod 5 can be accommodated in the second groove 22 , so that the second panel 2 can be completely accommodated on the upper surface of the first panel 1 .

When the utility model is in use, if no larger space is needed, the second panel 2 is kept on the first panel 1, and the utility model is a stool at this time; if a larger space is needed for storing articles or reading When learning, the second panel 2 is launched obliquely upwards, and the telescopic rod 5 falls out of the second groove 22, and it is stretched so that its end is placed in the cavity on the stool leg 3, providing the second panel 2 with The supporting force keeps the second panel 2 parallel to the first panel 1. At this time, the utility model transforms into a bench with a desk, which effectively expands the use space of the bench.

In summary, the utility model can retract the desktop, reduce the occupied space of the tables, chairs and benches, and improve the space utilization rate of the benches.
