Description

Technical Field

[0001] The utility model relates to the technical field of office supplies, in particular to an anti-slip office chair. Background Art

[0002] At present, most office chairs use a single immovable or universal movable base. The universal movable base has poor stability. If the user accidentally applies a little force in a certain direction, the office chair will start to move in a certain direction, which is less safe. The immovable base can only be moved manually when the office chair needs to be moved, which is inconvenient to move and affects the use effect. After searching, the Chinese patent publication number CN214258637U discloses a base of an office chair, which can prevent the anti-slip cover from being damaged due to long-term extrusion and friction and affecting the anti-slip of the base, can fold the moving wheels to improve the stability of the base, can prevent the office chair from being inconvenient to carry due to its heavy weight, and can prevent the office chair from being displaced due to a relatively smooth ground and causing wear to the base.

[0003] Although the above technical solution can achieve the anti-slip and mobile effects of the office chair, when in use, it is necessary to manually adjust the position of each moving wheel to make it contact and separate with the ground. The operation is relatively cumbersome and cannot be switched quickly, thereby increasing the workload. Utility Model Content

The backrest 13 can be manually rotated and fixed, or can be electrically driven to rotate, which can be selected according to actual conditions. It is a prior art and therefore is not described in detail. The backrest 13 and the headrest 14 are used for users to lean against.

[0023] Embodiment 2:

[0024] like Figures 1 to 3As shown, a lifting and moving mechanism 4 is fixedly installed inside the rectangular tube 3, and the lifting and moving mechanism 4 includes a top plate 41 fixedly installed on the top of the rectangular tube 3, and the lower surface of the top plate 41 is rotatably connected to a screw rod 42, and the outer surface of the screw rod 42 is threadedly connected to a rectangular block 43 that is slidably connected to the inner wall of the rectangular tube 3, and the bottom end of the rectangular block 43 is fixedly connected to a universal wheel 44. A first bevel gear 45 is fixedly sleeved on the outer surface of the top end of the screw rod 42, and the top plate 41 is fixedly connected to the top end of the rectangular tube 3 by bolts. The rotation of the first bevel gear 45 drives the screw rod 42 to rotate. When the screw rod 42 rotates forward, the rectangular block 43 and the universal wheel 44 are driven to move downward and contact the ground through the thread. At this time, the office chair can be moved by the universal wheel 44. When the screw rod 42 rotates reversely, the rectangular block 43 and the universal wheel 44 are driven to move upward through the thread, so that the rectangular anti-slip pad 10 at the bottom end of the rectangular tube 3 contacts the ground, thereby increasing the anti-slip property of the office chair, thereby achieving an anti-slip effect, and the support mode of the office chair can be quickly switched, thereby improving practicality.

[0025] Embodiment 3:

[0026] like Figures 1 to 3 As shown, a transmission mechanism 5 that cooperates with the lifting and moving mechanism 4 is installed inside the cross tube 2, and the transmission mechanism 5 includes bearing seats 51 symmetrically fixedly connected to both sides of the inner wall of the cross tube 2, and a transmission shaft 52 is rotatably connected between the two bearing seats 51, and one end of the transmission shaft 52 is fixedly connected to a second bevel gear 53 that meshes with the first bevel gear 45. One end of the transmission shaft 52 extends to the inside of the fixed seat 1 and is fixedly connected to a third bevel gear 54. The rotation of the third bevel gear 54 drives the transmission shaft 52 and the second bevel gear 53 to rotate, thereby driving the first bevel gear 45 to rotate.

[0027] Embodiment 4:

[0028] like Figures 1 to 3 As shown, a driving mechanism 6 matched with the transmission mechanism 5 is installed inside the fixed base 1, and the driving mechanism 6 includes a bottom plate 61 fixedly connected to the bottom end of the fixed base 1, and a driving motor 62 is fixedly installed on the upper surface of the bottom plate 61.

The bottom plate 61 is fixedly connected to the bottom end of the fixed base 1 by bolts. The rotation of the driving motor 62 drives the fourth bevel gear 63 to rotate, thereby driving multiple third bevel gears 54 to rotate at the same time. No manual operation is required, thereby reducing the workload and facilitating use, thereby solving the problem that the existing office chair needs to manually adjust the position of the moving wheel, which is inconvenient to operate and increases the workload.

[0029] Working principle: When in use, the driving motor 62 rotates to drive the fourth bevel gear 63 to rotate, thereby driving multiple third bevel gears 54 to rotate at the same time. The rotation of the third bevel gear 54 drives the transmission shaft 52 and the second bevel gear 53 to rotate, thereby driving the first bevel gear 45 to rotate. The rotation of the first bevel gear 45 drives the screw rod 42 to rotate. When the screw rod 42 rotates forward, the rectangular block 43 and the universal wheel 44 are driven to move downward and contact the ground through the thread. At this time, the office chair can be moved through the universal wheel 44. When the screw rod 42 rotates reversely, the rectangular block 43 and the universal wheel 44 are driven to move upward through the thread, so that the rectangular anti-skid pad 10 at the bottom end of the rectangular tube 3 contacts the ground, thereby increasing the anti-skid property of the office chair, thereby achieving an anti-skid effect, and the support mode of the office chair can be quickly switched, thereby improving practicality, without manual operation, thereby reducing the workload and facilitating use, thereby solving the problem that the existing office chair needs to manually adjust the position of the moving wheel, which is inconvenient to operate and increases the workload.

[0030] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
