DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1 The utility model provides a technical solution: a rotating desk.

[0026] Among them, the top of the base 1 is fixedly connected with a support column 101, the top of the support column 101 is provided with a mounting seat 102, the inner side wall of the mounting seat 102 is provided with a pressure block movable cavity 103, the center of the pressure block movable cavity 103 is provided with a threaded hole, a first ball cavity 104 is provided below the pressure block movable cavity 103, a second ball cavity 105 is provided at the bottom of the mounting seat 102, a round table base 201 is provided inside the mounting seat 102, a fixed tooth 202 is fixedly connected to the outside of the round table base 201, a pressure block 3 is provided inside the pressure block movable cavity 103, the front of the pressure block 3 is fixedly connected with the fixed tooth 202, a screw 301 is provided on the back of the pressure block 3, a handle 302 is fixedly connected to one side of the screw 301, and a ball 4 is provided inside the first ball cavity 104 and the second ball cavity 105.

[0027] In this embodiment, the round table base 201 is placed in the cavity at the center of the mounting seat 102, and a first ball cavity 104 and a second ball cavity 105 are opened on the surface of the round table base 201 and the mounting seat 102. The corresponding cavities can be aligned and a sufficient number of balls 4 can be placed therein. In this way, when the round table base 201 is rotated, the sliding friction between the round table base and the mounting seat is converted into rolling friction, which reduces the friction between the two, making the rotation more labor-saving and less noisy. The balls 4 also play a certain balancing and fixing role, preventing the round table base 201 from shaking in the mounting seat 102, affecting To balance the round table 2, when the operator rotates the round table 2 to a suitable position, the handle 302 on the side of the mounting base 102 is rotated, and the thread on the screw rod 301 behind the handle 302 is engaged with the threaded hole on the pressing block movable cavity 103. As the screw rod 301 is rotated, the pressing block 3 is pushed to move inward in the pressing block movable cavity 103 until the fixed teeth 202 on the pressing block 3 are engaged and fixed with the fixed teeth 202 on the round table base 201, and the round table base 201 is clamped by the pressing block 3, thereby preventing the round table 2 from rotating and fixing the round table 2. At this time, the operator can work on the stable round table 2.

[0028] The diameter of the ball 4 is greater than the groove depth of the first ball cavity 104 and the second ball cavity 105 .

[0029] In this embodiment, the ball 4 is embedded in two ball cavities 104, and the round table base 201 is lifted up by the ball 4, so that the round table base 201 is not in direct contact with the inner wall of the mounting base 102, avoiding friction between the two during rotation, resulting in unsmooth rotation. Long-term friction may also cause damage to the components.

[0030] The base 1 can be divided into two parts, and the two bases 1 are connected by fastening screws 106 .

[0031] In this embodiment, the base 1 can be split into two halves and fixed by fastening screws 106, which is more convenient during installation.

[0032] A circular boss is disposed on one side of the screw rod 301 .

[0033] In this embodiment, the circular boss is embedded in the center of the pressing block 3, and the screw 301 is used to pull the pressing block 3 through the circular boss, and the screw 301 will not drive the pressing block 3 to rotate when rotating, so that the fixed teeth 202 on the pressing block 3 can better engage with the fixed teeth 202 on the round table base 201.

[0034] The handle 302 has anti-slip patterns on its surface.

[0035] In this embodiment, the anti-slip pattern can increase the contact area between the handle 302 and the palm, and at the same time increase the friction, making it more convenient and labor-saving for the operator to turn the handle 302.

[0036] A round chamfer is provided between the base 1 and the support column 101 .

[0037] In this embodiment, the rounded chamfer increases the contact area between the base 1 and the support column 101, making the support column 101 more stable and the entire office desk is not easy to tip over.

[0038] Working principle: The round table 2 is arranged in the mounting seat 102 through the round table base 201, so as to be fixed on the support column 101, and the entire desk is supported by the base 1. When the round table 2 rotates, the sliding friction between the round table base 201 and the mounting seat 102 is converted into rolling friction through the rotation of the ball 4 in the first ball cavity 104 and the second ball cavity 105, thereby reducing the friction between the two and making the rotation more labor-saving. When it is rotated to a suitable position, the operator turns the handle 302 through the screw The thread on the rod 301 is meshed with the threaded hole on the pressing block movable cavity 103, pushing the pressing block 3 to move inward until the fixed teeth 202 inside the pressing block 3 are meshed with the fixed teeth 202 on the round table base 201, preventing the round table base 201 from rotating, thereby stopping and fixing the round table 2 to avoid accidental rotation of the round table 2 during use. When the position of the round table 2 needs to be adjusted again, it is only necessary to rotate the handle 302 in the opposite direction to disengage the handle 302 from the fixed teeth 202 on the round table base 201, and the round table 2 can be rotated again.
