All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0028] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] The following is further described in conjunction with specific embodiments. Refer to Figures 1-7As shown, the present embodiment is a modular desk, comprising a table top 1 and table legs 2, a universal wheel 3 is installed at the lower end of the table leg 2, a brake control assembly 4 is installed under the table top 1, the brake control assembly 4 comprises a mounting box 41, a brake line 43 and a slider 42, the slider 42 is slidably connected to the mounting box 41, both ends of the brake line 43 are respectively connected to the slider 42 and the universal wheel 3, and the brake line 43 is driven by the slider 42 to pull the universal wheel 3 to achieve locking; specifically, in an open classroom environment, in order to facilitate students to move the desks at will and lock them, they can pull the slider 42 with one hand, so that the slider 42 pulls and releases the brake line 43, when the brake line 43 is tightened, the universal wheel 3 is locked; and when the brake line 43 is loosened, the universal wheel 3 can be moved at will, its operation is more flexible, the locking effect of the universal wheel 3 is good, and the service life is longer.

[0030] like Figure 5 and Figure 6 In this embodiment, the universal wheel 3 includes a wheel disc 31, a flip bracket 32 ​​and a sleeve 33. A connecting shaft 34 is provided between the wheel discs 31. The sleeve 33 is sleeved on the connecting shaft 34 and is rotatably connected thereto. The sleeve 33 is connected to the table leg 2. One end of the flip bracket 32 ​​is sleeved with a torsion spring 35 and is rotatably connected to the sleeve 33. The other end of the flip bracket 32 ​​is connected to the brake line 43. A bayonet 321 is provided on both sides of the flip bracket 32. A cavity portion 311 and a slot portion 312 are provided on the end surface of the wheel disc 31. The slot portion 312 is provided with a cavity portion 311 and a slot portion 312. 12 are evenly spaced around the cavity portion 311, and the flip bracket 32 ​​is pulled by the brake line 43, so that the pin 321 is inserted into the slot portion 312 to achieve locking; specifically, the slider 42 pulls the brake line 43, the flip bracket 32 ​​rotates around its tail end, and the pin 321 of the flip bracket 32 ​​moves from the cavity portion 311 into the slot portion 312 to be locked, and the universal wheel 3 cannot move; and when the brake line 43 is released, the torsion spring 35 is reset, so that the pin 321 moves from the slot portion 312 into the cavity portion 311, and the universal wheel 3 can move normally.

[0031] In order to hide the brake line 43 and improve the aesthetics of the desk, the table leg 2 is designed to adopt a hollow structure, and the brake line 43 is laid along the inside of the table leg 2 and connected to the flip bracket 32.

[0032] like Figure 2 As shown, at least two brake wires 43 are provided in this embodiment; specifically, the brake wires 43 lock at least two universal wheels 3 to fully ensure that the desk cannot move.

[0033] For convenient operation, a knob 421 is provided on the slider 42, and the installation box 41 is provided with a sliding groove opening 411 adapted to the knob 421; and an unlocking and reset button 44 is provided on the installation box 41; specifically, the knob 421 drives the slider 42 to move along one side of the unlocking and reset button 44 in the sliding groove opening 411, and the brake cable 43 will be tightened to firmly lock the desk; and when the unlocking and reset button 44 is pressed, the slider 42 will reset, so that the brake cable 43 retracts, and the desk returns to normal mobility, with simple and convenient operation.

[0034] As Figure 2 and Figure 7 shown, in order to improve the stability of the support of the table leg 2, a support plate 21 is provided at the upper end of the table leg 2. The support plate 21 can be a circular or square plate, and an installation hole 211 is opened in the middle of the support plate 21; at least two limit moving pins 212 are provided on the support plate 21 for inserting into the tabletop 1, and a screw 11 is provided above the tabletop 1 for screwing into the installation hole 211 to connect with it; specifically, it avoids the situation that the table leg 2 rotates when the screw 11 is screwed into the table leg 2. At the same time, compared with the traditional installation of the tabletop 1, when holding the tabletop 1 and aligning and inserting the jacks adapted to the limit moving pins 212 opened on the tabletop 1, the screw 11 can be directly passed through from above the tabletop 1 and screwed into the installation hole 211. This installation method is more convenient and also facilitates disassembly and transportation, so that the table leg 2 and the tabletop 1 can be stably connected only by rotating the table leg 2 and a customized screw 11 passing through the tabletop.

[0035] In addition, multiple limit moving pins 212 are arranged at equal intervals around the installation hole 211. They can be cylindrical or square column structures, but the length of the limit moving pins 212 does not exceed the thickness of the tabletop 1, so that compared with the traditional tabletop 1 which is connected and fixed by passing through the support plate 21 from below and screwing in fastening screws, the fastening screws cannot be seen on the back of the tabletop 1, and its assembly method is simpler and easier to operate.

[0036] As Figure 1 shown, this tabletop 1 is a quadrilateral structure, which is convenient for combination and piecing according to the use scenario, effectively shortening the communication distance, and the table corners of the tabletop 1 are arc edges, effectively preventing bumps and injuries.

[0037] In addition, the tabletop 1 in this embodiment is made of multi-layer solid wood materials, or the tabletop 1 is processed with other materials.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
