Description

Technical Field

[0001] The utility model relates to the technical field of tabletop furniture, in particular to a portable computer table installed on a chair armrest. Background Art

[0002] In an era of increasingly fast-paced life, everyone is in a state of busy work. Sometimes, they even need to work from home to handle work. When many people work from home or work outside the home, sometimes there is no space to place the computer because there are too many sundries on the desktop. They directly put the computer on their thighs or other supporting objects, which is extremely inconvenient. Therefore, many chairs are correspondingly equipped with small table boards that can be used as temporary desktops.

[0003] In the prior art, generally, two sleeves that can be sleeved on the chair armrests are arranged under the table board. The table board is fixed by sleeving the sleeves on the chair armrests and can be directly used as a temporary table board, which is very convenient. However, in fact, many sleeves of the table boards are only adapted to the armrests of one type of chair. When the size of the supporting chair armrest does not perfectly match the size of the table board sleeve in the prior art, there may be problems such as the armrest being too large to be sleeved or the armrest being too small, resulting in the table board being unstable and shaking during installation, and the practicability is not strong, with strong limitations. Therefore, a computer table with a more reasonable structure is needed to solve the above-mentioned technical problems. Summary of the Utility Model

[0004] Aiming at the deficiency that the sleeve of the table board in the above technology cannot be installed on the armrests of other chairs, the utility model provides a portable computer table installed on a chair armrest.

[0005] To achieve the above object, the utility model provides a portable computer table installed on a chair armrest, which is characterized in that it includes a table board main body. The table board main body includes a working surface and an installation surface. At least two table board sliding mechanisms and at least two armrest sleeves are arranged on the installation surface. One table board sliding mechanism is fixedly connected to one armrest sleeve correspondingly. A threaded hole is arranged on the surface of the armrest sleeve away from the table board sliding mechanism, and the threaded hole is connected with an adjusting knob. During work, the armrest sleeve is sleeved on the chair armrest, and the adjusting knob is tightened to fix the armrest sleeve and the chair armrest to each other. The table board main body slides linearly in the front-back direction relative to the armrest sleeve through the table board sliding mechanism.

[0006] As an improved solution of the present utility model, a first sunken groove is provided on the working surface of the tabletop main body. A support frame and a support plate are provided in the first sunken groove. One end of the support frame is rotatably provided on the support plate. A plurality of adjustment grooves are provided on the groove bottom surface of the first sunken groove. The other end of the support frame is adapted to the adjustment grooves. Rotating columns are provided on both sides of the support plate, and groove holes adapted to the rotating columns are provided on the groove wall surface of the first sunken groove.

[0007] As an improved solution of the present utility model, a cup holder is provided on the installation surface, and the cup holder is rotatably connected to the tabletop main body.

[0008] As an improved solution of the present utility model, the tabletop main body includes a first tabletop and a second tabletop, and the first tabletop and the second tabletop are flip-connected through a hinge member.

[0009] As an improved solution of the present utility model, a second sunken groove is provided on the surface of the support plate away from the first sunken groove. A support bar for supporting a laptop is provided in the second sunken groove, and the support bar is flip-connected to the support plate.

[0010] As an improved solution of the present utility model, the tabletop sliding mechanism includes a connecting member and a sliding member. The sliding member is fixedly provided on the installation surface, and the connecting member is provided between the tabletop main body and the sliding member. A strip-shaped groove hole is provided on the sliding member. A connecting column adapted to the strip-shaped groove hole is provided on the surface of the armrest sleeve close to the tabletop main body. An installation hole is provided on the end surface of the connecting column. A connecting groove is provided on the connecting member, and a connecting hole is provided on the groove bottom of the connecting groove. The connecting column is embedded into the connecting groove through the strip-shaped groove hole.

[0011] As an improved solution of the present utility model, serrated protrusions are provided on the inner wall surfaces at opposite ends of the sliding member, and clamping grooves adapted to the protrusions are provided on both sides of the connecting member.

[0012] As an improved solution of the present utility model, turning parts are formed at the edges of the support plate and the support bar away from the hinged ends.

[0013] As an improved solution of the present utility model, an arc-shaped avoidance part is formed at the edge of the tabletop main body.

[0014] As an improved solution of the present utility model, a third sunken groove is provided on the tabletop main body, and a mouse pad is provided in the third sunken groove.

[0015] The beneficial effects of the present utility model are as follows: Compared with the prior art, a portable computer desk installed on the armrest of a chair provided by the present utility model is characterized in that it includes a tabletop main body.

[0034] Please refer to Figures 1-2 and Figure 9 On the working surface of the tabletop main body 1, there is a first sunk groove 5. In the first sunk groove 5, there are a support frame 51 and a support plate 52. One end of the support frame 51 is rotatably arranged on the bottom surface of the first sunk groove 5; both sides of the support plate 52 are hinged to the groove walls of the first sunk groove 5; on the surface of the support plate 52 close to the first sunk groove 5, there are a plurality of adjustment grooves 53, and the other end of the support frame 51 is adapted to the adjustment grooves 53; on both sides of the support plate 52, there are rotating columns 521, and on the groove wall surface of the first sunk groove 5, there are groove holes adapted to the rotating columns 521; the first sunk groove 5 is mainly used for storing the support frame 51 and the support plate 52. When in use, the support plate 52 and the support frame 51 are correspondingly turned up, and one end of the support frame 51 is abutted against the adjustment grooves 53, and the support plate 52 maintains a certain use angle, then the computer can be placed on the support plate 52. At the same time, on the side of the support plate 52 away from the first sunk groove 5, there is a second sunk groove 522. In the second sunk groove 522, there is a support bar 7 for abutting against the laptop. The support bar 7 is rotatably connected to the support plate 52. After the support bar 7 is opened, it can prevent the laptop from slipping off the support plate 52. Further, on the surface of the support plate 52, there are a plurality of heat dissipation holes 8 for helping the computer dissipate heat, and on the support plate 52 and the support bar 7, there are also arc-shaped turning parts 12. The user can turn the support plate 52 and the support bar 7 by buckling the turning parts 12 with fingers.

[0035] Please refer to Figure 4 In this embodiment, the tabletop main body 1 includes a first tabletop 101 and a second tabletop 102. The first tabletop 101 and the second tabletop 102 are rotatably connected by a hinge 11. When the manufacturer ships the product by express delivery, due to the large volume of the tabletop main body 1, the corresponding express delivery cost will increase a lot. Therefore, the tabletop main body 1 is designed as the first tabletop 101 and the second tabletop 102, and the two can be folded and turned for storage through the hinge 11, reducing the volume of the tabletop and further reducing the manufacturer's expenditure cost. At the same time, from the user's perspective, the foldable tabletop can also reduce the space it occupies.
