[0031] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0032] Such as Figures 1 to 16As shown in the figure, a new type of desk includes a left leg 1, a right leg 2, a desk drawer 3, a desktop 4, a front support bar 5 and a rear baffle 6. Installation grooves 7 are provided on the top surfaces of the left and right legs 1 and 2. Horizontal flanges 8 are provided on the left and right sides of the top of the desk drawer 3. The horizontal flanges 8 on the left and right sides of the desk drawer 3 are correspondingly lapped on the installation grooves 7 on the top surfaces of the left and right legs 1 and 2 and are connected to the left and right legs 1 and 2 by countersunk head screws. Socket joints 9 are correspondingly provided at the front and rear ends of the tops of the left and right legs 1 and 2. Socket holes 10 matching the socket joints 9 are provided at the left and right ends of the front support bar 5 and the rear baffle 6, and threaded holes 11 are provided in the socket holes 10. The socket joints 9 are inserted into the socket holes 10 for positioning. A U-shaped opening 12 is provided in the side wall of the installation groove 7 corresponding to the socket joint 9. The front support bar 5 and the rear baffle 6 are fixed between the left and right legs 1 and 2 by screwing through the U-shaped opening 12 and connecting with the threaded holes 11. A first support plate 13 is folded forward at the bottom end of the rear baffle 6, and the top surface of the first support plate 13 is on the same horizontal plane as the top surface of the front support bar 5. The bottom surface of the desktop 4 is fixedly bonded to the top surfaces of the first support plate 13 and the front support bar 5 by adhesive.

[0033] In this embodiment, the desktop 4 shields the installation grooves 7 at the tops of the left and right legs 1 and 2, thereby shielding and hiding all the screws used for installation.

[0034] In this embodiment, shielding blocks 14 are provided at both ends of the rear baffle 6. A connecting plate 15 is horizontally provided at the bottom end of the shielding block 14. The connecting plate 15 is fixed in the installation groove 7 by screws. Plugging holes 16 are provided at the left and right ends of the rear baffle 6, and one end of the shielding block 14 is inserted into the plugging holes 16.

[0035] Since the rear baffle 6 has a certain thickness, the part of the installation groove 7 corresponding to the side of the rear baffle 6 cannot be shielded by the desktop 4 after the desktop 4 is assembled, resulting in an unattractive appearance. Therefore, shielding blocks 14 are additionally provided at both ends of the rear baffle 6 to shield this part. The connecting plate 15 at the bottom of the shielding block 14 is located in the installation groove 7 and is shielded and hidden by the desktop 4.

[0036] In this embodiment, a middle support bar 17 is further included. Threaded holes 11 are provided at both left and right ends of the middle support bar 17. A receiving groove 18 is provided at the middle position of the tops of the left and right legs 1 and 2. Both ends of the middle support bar 17 are fitted in the receiving groove 18. A U-shaped opening 12 is provided in the side wall of the installation groove 7 corresponding to the receiving groove 18. The middle support bar 17 is fixed between the left and right legs 1 and 2 by screwing through the U-shaped opening 12 and connecting with the threaded holes 11. A horizontal flange 8 is provided at the rear side of the top of the desk drawer 3. The horizontal flange 8 is lapped on the middle support bar 17 and is fixed by countersunk head screws.

[0037] The setting of the middle support bar 17 further improves the stability of the installation of the desk drawer 3, and the countersunk head screws used for installation are shielded and hidden under the desktop 4.

[0038] In this embodiment, the left and right legs 1 and 2 both include a top support member 19, a connecting rod 20, and a bottom support 21. The top of the top support member 19 is an installation groove 7, and the bottom of the top support member 19 is provided with an upper positioning insert 22. A through hole 23 is formed in the connecting rod 20, and a threaded hole 11 is fixedly provided in the through hole 23. The top support member 19 is inserted into the top of the connecting rod 20 through the upper positioning insert 22, and the top support member 19 is fixedly connected to the connecting rod 20 by screwing a screw downward from the installation groove 7 into cooperation with the threaded hole 11. The bottom of the bottom support 21 is provided with a cavity 24, a screw mounting seat 25 is provided corresponding to the connecting rod 20, and the top of the bottom support 21 is provided with a lower positioning insert 26. The bottom support 21 is inserted into the bottom of the connecting rod 20 through the lower positioning insert 26, and a screw is arranged in the screw mounting seat 25 to cooperate with the threaded hole 11 to realize the fixed connection between the bottom support 21 and the connecting rod 20.

[0039] A recess 27 is provided on the outer side wall of the connecting rod 20 in the vertical direction, and sliding grooves 28 are provided on both sides of the recess 27. A decorative plate 29 is fitted in the recess 27, and sliding plates 30 that cooperate with the sliding grooves 28 are provided on both sides of the decorative plate 29. A rib 31 is arranged on the inner side of the decorative plate 29 in the vertical direction, so that there is a gap between the inner wall of the decorative plate 29 and the bottom surface of the recess 27, and this gap is beneficial to the installation of the screw.

[0040] To provide structural strength, a reinforcing rod 32 is provided between the left and right legs 1 and 2, and the reinforcing rod 32 is connected to the end of the reinforcing rod 32 by screwing a screw horizontally through the connecting rod 20 from the recess 27 on the outer side wall of the connecting rod 20. Since the screw is located at the position of the recess 27, the screw is blocked and hidden by the decorative plate 29.

[0041] In this embodiment, a rectangular opening 33 identical to the through hole on the connecting rod 20 is formed in the bottom support 21.

[0042] In actual use, to satisfy the fixed connection between the desk and the ground, a foundation fixing member 34 is further included. The foundation fixing member includes a foundation connecting plate 341 and a vertical plate 342. A threaded hole is provided on the vertical plate 342. The foundation connecting plate 341 is horizontally connected to the bottom end of the vertical plate 342, and mounting holes 343 are provided on the foundation connecting plate 341.

[0043] The foundation fixing member 34 is connected and fixed to the ground through the mounting holes 343 on the foundation connecting plate 341. The vertical plate 342 extends upward through the rectangular opening 33 into the through hole 23 of the connecting rod 20. A through hole is formed in the recess 24 corresponding to the threaded hole on the vertical plate 342, and connection is made by screwing a screw, thereby fixing the desk to the ground. The screws used for installation are blocked and hidden by the decorative plate 29.

[0044] Thus, there are no exposed screws in the present utility model, avoiding the occurrence of students being injured due to colliding with the exposed screws.
