The desk belly can hold school bags, school supplies and other miscellaneous items. Although the above patent is convenient for placing and finding books, it is necessary to remove stationery and other items on the table top board before opening the table top board to take out books, which is inconvenient to operate. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the present application provides a hidden bookshelf-type student desk.

[0004] The present application provides a hidden bookshelf student desk that adopts the following technical solution:

[0005] A student desk with a hidden bookshelf comprises a desk main body, which comprises a desk top and legs for supporting the desk top, wherein a desk belly is provided under the desk top, and the legs on both sides of the desk top are connected by a crossbeam, and a bookshelf assembly is installed at the bottom of the desk belly; the bookshelf assembly comprises a bookshelf and a connecting mechanism, the connecting mechanism connects the top surface of the bookshelf with the bottom surface of the desk belly, the connecting mechanism comprises a limiting guide rail and a limiting slider that cooperates with the limiting guide rail for transmission, wherein the limiting guide rail is installed on the bottom surface of the desk belly, the limiting slider is installed on the top surface of the bookshelf, and the limiting slider is rotatably connected to the top surface of the bookshelf, the opening of the bookshelf is located on the front of the desk main body, and a power mechanism for driving the desk to move on the bottom surface of the desk belly is also installed at the bottom of the desk belly.

[0006] By adopting the above technical solution, the desk body is composed of a table top, a table belly, table legs and a crossbeam connecting the table legs, which constitute the basic structure of the desk. The bookshelf assembly is set at the bottom of the table belly. Under the action of the power mechanism, the bookshelf slides on the limit guide rail on the bottom of the table belly through the limit slider at its top, so that the bookshelf can be moved back and forth at the bottom of the table belly. The limit slider is also rotatably connected to the top surface of the bookshelf. When the power mechanism drives the bookshelf to the front end of the desk, the opening of the bookshelf can be rotated upward. After the rotation, books can be taken and placed in a sitting position without bending over to take and place books. It is worth noting that the limit slider can be stuck on the limit guide rail and can withstand the load of the bottom bookshelf when it is full of books. The limit guide rail is installed in the groove at the bottom of the table belly, and the rear end of the groove does not extend out of the bottom plate of the table belly. A blocking block is fixedly installed at the front end of the groove. The blocking block is installed after the limit slider is stuck on the limit guide rail.

[0007] Preferably, the bookshelf is provided with multiple layers, and the bottom plate and the back plate of each layer of the bookshelf are inclined toward the inside of the bookshelf.

[0008] By adopting the above technical solution, the multi-layer structure of the bookshelf is convenient for the classified storage of different types of books. The design of the bottom plate and back plate of the bookshelf tilted towards the inside of the bookshelf makes the books placed therein more stable. Even if the desk is moved and tilted at a certain angle, it is not easy for the books in the bookshelf to fall.

[0009] Preferably, a handle is installed at the bottom of the front of the bookshelf, and anti-kick buffer pads are installed on both sides of the handle.

[0010] By adopting the above technical solution, the handle installed at the bottom of the front of the bookshelf makes it convenient for students to turn the bookshelf up, and the anti-kick cushions provided on both sides of the handle can effectively avoid injuries from collisions with students' legs.

[0011] Preferably, the connections between the bottom surface of the bookshelf and the front and back surfaces thereof are arc-shaped transitions.

[0012] By adopting the above technical solution, it is avoided that the bookshelf collides with the students' limbs during the rotation process and causes injuries.

[0013] Preferably, the limiting guide rail is located at the bottom center of the table belly, and sliding grooves are symmetrically provided on both sides of the limiting guide rail. A sliding block adapted thereto is provided on the top of the bookshelf, and the sliding block is located on the side of the limiting slider close to the front of the bookshelf.

[0014] By adopting the above technical solution, the limiting guide rail is located at the center of the table, allowing the limiting slider that cooperates with it to be located at the center of the bookshelf top. At the same time, the sliding grooves on both sides of the limiting guide rail cooperate with the sliding block on the top of the bookshelf, and the power mechanism can drive the bookshelf to move forward and backward stably. The sliding block is located on the side of the limiting slider closest to the front of the bookshelf. When the limiting slider moves to the side closest to the front of the bookshelf, the sliding block on the top of the bookshelf has disengaged from the sliding groove on the bottom of the table, allowing the bookshelf to rotate.

[0015] Preferably, the slide groove adopts an M-shaped structure, and the sliding block adopts a T-shaped structure, wherein a plurality of groups of rollers capable of sliding along the length direction of the slide groove are installed on both sides of the sliding block.

[0016] By adopting the above technical solution, the sliding groove of the M-shaped mechanism can clamp the sliding block therein for sliding, and cooperate with the rollers on both sides of the sliding block to reduce the friction between the two when relative displacement occurs, thereby making the movement of the bookshelf smoother.

[0017] Preferably, two groups of buffer blocks are installed on the top of the bookshelf. The buffer blocks are located on the side of the limiting slider away from the sliding block, and detachable rubber buffer layers are installed on the top and back surfaces of the buffer blocks.

[0018] By adopting this technical solution, the two sets of buffer blocks on the top of the bookshelf can reduce damage caused by the top of the bookshelf hitting the bottom of the desk when the bookshelf rotates, thereby increasing the service life of the entire bookshelf assembly. The buffer blocks are arranged in two symmetrical groups. When the bookshelf moves close to the back of the desk, the gaps between the buffer blocks can accommodate the motor and avoid position conflicts with the lead screw, thus rationally allocating and utilizing space. The rubber buffer layers installed on the top and back of the buffer blocks can be replaced after long-term use, facilitating maintenance of the bookshelf assembly.

[0019] Preferably, the power mechanism includes a motor installed at the end of the bottom surface of the table belly, the lead screw at the output end of the motor cooperates with the threaded sleeve in the limiting slider for transmission, and the lead screw is distributed along the length direction of the limiting guide rail.

[0020] By adopting the above technical solution, the power mechanism uses a motor to drive the screw to rotate and cooperate with the screw sleeve in the limit slider to drive the bookshelf to move back and forth on the bottom surface of the table belly, and the start and stop of the motor can be carried out by using the operation buttons set on the desk body or remote control.

[0021] In summary, this application has the following beneficial technical effects:

[0022] The present application achieves this by sliding the bookshelf onto the bottom surface of the desk. When storing books, the bookshelf can be moved to the side close to the back of the desk without affecting the placement of students' legs and feet. When books need to be taken, the power mechanism can drive the bookshelf to move to the front of the desk, and students can conveniently organize and take and put textbooks by grasping the handle and rotating the bookshelf. The operation is convenient, and there is no need to move items on the desk top. There is no need to bend over or squat to operate when taking and putting books, which greatly improves the comfort of taking and putting books. BRIEF DESCRIPTION OF THE DRAWINGS

The desk body 1 is composed of a table top 11, a table belly 13, table legs 12 and a crossbeam 121 connecting the table legs 12, which constitute the basic structure of the desk. The bookshelf assembly 2 is set at the bottom of the table belly 13. Under the action of the power mechanism 23, in conjunction with the connecting mechanism 22 located between the bookshelf 21 and the bottom of the table belly 13, the bookshelf 21 slides on the limiting guide rail 221 on the bottom surface of the table belly 13 through the limiting slider 222 at its top, and moves the bookshelf 21 back and forth at the bottom of the table belly 13, and the limiting slider 222 is also rotatably connected to the top surface of the bookshelf 21. When the power mechanism 23 drives the bookshelf 21 to the front end of the desk, the opening of the bookshelf 21 can be rotated upward. After rotation, books can be taken and placed in a sitting state without bending over to take and place books. It is worth noting that the limit slider 222 can be stuck on the limit guide rail 221 and can withstand the load when the bookshelf 21 at the bottom is full of books. The limit guide rail 221 is installed in the groove at the bottom of the table belly 13, and the rear end of the groove does not extend out of the bottom plate of the table belly 13. A blocking block is fixedly installed at the front end of the groove. The blocking block is installed after the limit slider 222 is stuck on the limit guide rail 221.

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4The bookshelf 21 is provided with two layers, and the bottom plate and back plate of each layer of the bookshelf 21 are tilted toward the inside of the bookshelf 21. The multi-layer structure of the bookshelf 21 facilitates the classified storage of different types of books. The design of the bottom plate and back plate of the bookshelf 21 tilting toward the inside of the bookshelf 21 makes the books placed therein more stable. Even when the desk is moved and tilted at a certain angle, it is not easy for the books in the bookshelf 21 to fall. A handle 211 is also installed at the bottom of the front of the bookshelf 21, and anti-kick cushions 212 are installed on both sides of the handle 211. The handle 211 installed at the bottom of the front of the bookshelf 21 makes it convenient for students to rotate the bookshelf 21 up, and the anti-kick cushions 212 provided on both sides of the handle 211 can effectively prevent injuries from colliding with students' legs. The bottom surface of the bookshelf 21 is connected to its front and back surfaces respectively with an arc-shaped transition 213. This prevents the bookshelf 21 from colliding with students' limbs and causing injuries during the rotation process.

[0032] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4The limiting guide rail 221 is located at the bottom center of the table base 13. Slide grooves 223 are symmetrically provided on both sides of the limiting guide rail 221. A matching sliding block 214 is provided at the top of the bookshelf 21, and the sliding block 214 is located on the side of the limiting slider 222 closest to the front of the bookshelf 21. The limiting guide rail 221 is located at the center of the table base 13, allowing the limiting slider 222, which it drives in conjunction with, to be positioned at the center of the top of the bookshelf 21. The sliding grooves 223 on both sides of the limiting guide rail 221 cooperate with the sliding block 214 on the top of the bookshelf 21, and under the action of the power mechanism 23, the bookshelf 21 can be driven to move forward and backward stably. Furthermore, the sliding block 214 is located on the side of the limiting slider 222 closest to the front of the bookshelf 21. When the limiting slider 222 moves to the side closest to the front of the bookshelf 21, the sliding block 214 on the top of the bookshelf 21 disengages from the sliding grooves 223 on the bottom of the table base 13, allowing the bookshelf 21 to rotate. The chute 223 has an M-shaped structure, and the sliding block 214 has a T-shaped structure. The sliding block 214 is mounted on both sides with several sets of rollers 215 that can slide along the length of the chute 223. The M-shaped chute 223 can hold the sliding block 214 therein for sliding. The rollers 215 on both sides of the sliding block 214 reduce friction when relative displacement occurs between the two, thereby making the movement of the bookshelf 21 smoother. Two sets of buffer blocks 216 are also mounted on the top of the bookshelf 21. The buffer blocks 216 are located on the side of the limiting slider 222 away from the sliding block 214.
