Abstract
Description
Technical Field
[0001] This utility model relates to the field of office desk technology, and in particular to a structurally optimized office desk. Background Technology
[0002] Larger tables are used in places such as shopping malls and conference rooms for office work. Compared with traditional desks, they are larger in size, inconvenient to move, and do not have height adjustment function, which greatly limits their convenience of use.
[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0004] An optimized office desk includes an office desktop and telescopic support legs located at the four corners of the bottom of the office desktop. It also includes hollow support legs that cooperate with the telescopic support legs. The telescopic support legs are slidably arranged relative to the hollow support legs. A locking structure is provided in the telescopic support legs. The locking structure has two states: a locked state and an open state. The state of the locking structure can be adjusted by rotation. In addition, an auxiliary spring is provided in the hollow support legs to support the weight of the telescopic support legs and the office desktop.
[0005] Preferably, the locking structure includes a bearing embedded in the telescopic support leg and a screw rod. The screw rod is interference-fitted with the inner ring of the bearing. A manual knob is fixedly provided at the upper end of the screw rod, and the manual knob protrudes from the upper surface of the office desk. A locking device is provided at the lower end of the screw rod. Blind grooves are provided at intervals on the inner walls of the front and rear sides of the hollow support leg. The locking device is inserted into the blind groove after being rotated horizontally.
[0006] Preferably, the locking device includes a locking block and two horizontally inserted blocks at both ends of the locking block, and a spring is provided inside the locking block to push the two inserted blocks outward.
[0007] Preferably, the left and right sidewalls of the telescopic support foot are provided with rubber rollers that roll at intervals, and the rubber rollers make rolling contact with the inner sidewall of the hollow support foot, thereby improving the smoothness of telescopic movement.
[0008] Preferably, the hollow support foot is provided with an auxiliary spring, the lower end of the auxiliary spring abuts against the inner bottom wall of the hollow support foot, the upper end of the hollow support foot abuts against the lower end of the locking device, and the contact surface is provided with grease to facilitate relative rotation.
[0009] Preferably, the elastic force of the auxiliary spring should be such that when the locking device is in the unlocked state and there are no debris on the office desk, the auxiliary spring will fully lift the telescopic support leg to the upper limit position, and the auxiliary spring will be compressed when a vertical downward force applied to the office desk does not exceed 100 Newtons. This way, it is not difficult to adjust upwards and it is also relatively easy to adjust downwards.
[0010] Preferably, the exposed manual knob position on the office desk is covered with a rubber cover to ensure a flat and aesthetically pleasing desktop.
[0011] The advantages and positive effects of this utility model are:
[0012] 1. It has a simple structure, is easy to use, and the height can be adjusted effortlessly. It is supported by an auxiliary spring, which can be easily adjusted to a suitable height and locked. It has low production costs and good commercial value. Attached Figure Description

It also includes hollow support legs 10 configured to cooperate with the telescopic support legs 11. The telescopic support legs 11 are slidably disposed relative to the hollow support legs 10. A locking structure is provided in the telescopic support legs 11. The locking structure has two states, namely a locked state and an open state. The state of the locking structure can be adjusted by rotation. In addition, an auxiliary spring is provided in the hollow support legs 10 to support the weight of the telescopic support legs 11 and the office desk surface 12.
[0023] Preferably, the locking structure includes a bearing 15 embedded in the telescopic support leg 11 and a screw rod 14. The screw rod 14 is interference-fitted with the inner ring of the bearing 15. A manual knob 17 is fixedly provided at the upper end of the screw rod 14, and the manual knob 17 protrudes from the upper surface of the office desktop 12. A locking device 19 is provided at the lower end of the screw rod 14. Blind grooves 18 are provided at intervals on the front and rear inner walls of the hollow support leg 10. The locking device 19 is inserted into the blind grooves 18 after being rotated horizontally (e.g., ...). Figure 2-4 In the unlocked state, the locking device 19 is not in contact with the hollow support leg 10; when the locking device 19 is in the locked state... Figure 2 (Based on the premise of rotating 90 degrees so that its two ends are inserted into the blind groove 18 for locking).
[0024] Preferably, the locking device 19 includes a locking block 20 and two horizontally inserted blocks 21 at both ends of the locking block 20. A spring is provided inside the locking block 20 to push the two inserted blocks 21 outwards. The locking device 19 rotates as a whole.
