Examples

The utility model discloses a computer desk structure suitable for disabled person teaching, which is shown in fig. 1-2 and comprises a computer desk surface 1, a support frame 2 and a keyboard rack 3; the computer desktop 1 is provided with a wiring hole 10, the computer desktop 1 is further provided with a hanging piece 14, and the hanging piece 14 is preferably arranged on the side edge of the computer desktop 1 so as to facilitate hanging of objects such as earphones and the like.

Wherein, support frame 2 sets up in computer desktop 1 below, and the inboard of support frame 2 still is equipped with host computer and holds chamber 20, and support frame 2 includes the vertical bracing piece 21 of locating computer desktop 1 below, is used for the connecting rod 22 of fixed support bar 21 and sets up the altitude mixture control subassembly 23 between computer desktop 1 and bracing piece 21.

In practical applications, four support rods 21 are preferably provided at four azimuth angles below the computer desk 1 to provide stable support for the computer desk structure. In order to fix the four support rods 21, a connection rod 22 is further disposed between adjacent support rods 21, and no connection rod 22 is disposed between two adjacent support rods 21 at the lower front end of the computer desktop 1, so as to provide a lower space for a user (wherein, an end of the computer desktop 1 close to the user is referred to as a front end, and vice versa is referred to as a rear end).

In practical applications, the support rod 21 has a hollow structure, and preferably, the support rod 21 is a hollow cylinder. Among them, some disabled people with inconvenient legs and feet often need to walk by means of a wheelchair, and the height of the seat of the wheelchair is small; however, some users who have inconvenience in legs and feet cannot bend legs and sit down because the legs are bound by bandages and the like, and can only learn in a standing posture, therefore, in order to adapt to different users, a height adjusting assembly 23 for adjusting the computer desktop 1 is further arranged.

The height adjusting assembly 23 includes a telescopic rod 230 and a fastening member 231, the upper end of the telescopic rod 230 is fixedly connected to the computer desktop 1, the lower end of the telescopic rod 230 is sleeved in the supporting rod 21 through a hollow structure, the fastening member 231 is disposed on the upper end side surface of the supporting rod 21, and the fastening member 231 penetrates through the supporting rod 21 and is detachably connected to the telescopic rod 230. For example, the detachable connection of the fastener 231 to the extension pole 230 includes, but is not limited to, a screw connection; when the fastening member 231 is spirally connected with the telescopic rod 230, the fastening member 231 is unscrewed, the telescopic rod 230 is moved upwards or downwards to an appropriate height, and the height adjustment of the computer desktop 1 can be completed by tightening the fastening member 231, which is particularly suitable for learners who have inconvenience in legs and feet.

In addition, the bottom of the support rod 21 is provided with a buffer gasket 24, so that the friction between the computer desk structure and the ground can be reduced in the process that the computer desk structure moves from the ground, the ground is prevented from being scratched, and the generation of harsh noise can be avoided.

In this embodiment, the keyboard frame 3 is disposed in front of the computer desktop 1, the keyboard frame 3 includes an object placing plate 31, a sliding component 30 and a connecting member 32, the sliding component 30 is disposed at the bottom of the computer desktop 1, the sliding component 30 includes a first fixing plate 300 and a strip-shaped sliding hole 301 disposed on the first fixing plate 300, the rear end of the connecting member 32 is disposed in the strip-shaped sliding hole 301, and is hinged to the first fixing plate 300 through the strip-shaped sliding hole 301, and the upper portion of the first fixing plate 300 is fixed on the computer desktop 1. The object placing plate 31 is used for placing objects such as a keyboard and a mouse, the bottom of the rear end of the object placing plate 31 is provided with a second fixing plate 311, and the front end of the connecting piece 32 is hinged to the second fixing plate 311.
