Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples.

Example 1

With reference to fig. 1 and 2, a single-side supporting frame for a drawing board of this embodiment includes a top plate 1, a cylinder 2, a first piston 3, a supporting rod 4, and a frame body 7; the top plate 1 is movably arranged at the top end of the frame body 7; the frame body 7 is hollow and is communicated with the cylinder body 2 through an air pipe 6; a first piston 3 is arranged in the cylinder body 2, and the first piston 3 is connected with a support rod 4; the supporting rod 4 supports the top plate 1. A sliding groove is formed in the lower end face of the top plate 1, a sliding block 10 (see fig. 3) is arranged in the sliding groove, and the sliding block 10 can slide in the sliding groove along the horizontal direction; the support rod 4 is connected with the slide block 10, and the top plate 1 is supported by the slide block 10. The supporting frame is locked by gas and the piston, so that parts required by internal locking are reduced, the possibility of damage of the parts is avoided, and the possibility of failure of the supporting frame is reduced. Simultaneously because support body 7 is inside cavity, the whole weight of support frame is lighter, conveniently removes and carries it.

In this embodiment, two cylinder bodies 2 are arranged, and are symmetrically arranged on two sides of the frame body 7; correspondingly, the first piston 3 and the air pipe 6 are also arranged in two, and are symmetrically arranged on two sides of the frame body 7. The lower end of the top plate 1 is fixedly connected with a second piston 11, the second piston 11 penetrates through the frame body 7, and the bottom of the second piston extends into an air chamber 13 at the bottom end of the frame body 7.

With reference to fig. 4 and 5, the support rod 4 of the present embodiment has a connecting rod 43 at one end, an oval through hole 41 at the other end, and a fixing hole 42 at the middle position; the first piston 3 is connected with the support rod 4 through the fixing hole 42, and the support rod 4 can rotate along the fixing hole 42. 7 both sides of support body set up a connecting block 5 respectively, offer the hole on the connecting block 5, bracing piece 4 passes through connecting rod 43 and is connected with connecting block 5, and bracing piece 4 can rotate around connecting block 5. The single-side supporting frame for the drawing board utilizes the top plate 1 to support one side of the drawing board, and is matched with an office table in a dormitory to achieve the purpose of the drawing board. The utility model discloses the volume is less, only supports drawing board one side, can be convenient place in the dormitory.

In this embodiment, the air chamber 13 is communicated with the outside, and the communication position is blocked by the air cap 12. The air chamber 13 is arranged on the base 8, and the two reinforcing strips 9 are welded at the bottom of the base 8 in a crossed manner.

This embodiment is when using, because drawing board gravity makes roof 1 have a downward trend, and drives bracing piece 4 and withstands both sides cylinder body 2, makes second piston 11 realize fixing to realize roof 1's auto-lock, reduced the second piston 11 that air compression arouses and floated from top to bottom, make the drawing board place more steadily.

When the support frame of the embodiment is used, the air cap 12 is firstly unscrewed, so that the support frame is filled with air, and the support rod 4 is not connected with the slider 10 firstly. One end of the drawing board is placed on the office table and the other end is placed on the top board 1. At this time, the top plate 1 and the second piston 11 move downwards under the gravity of the drawing board until the top plate 1 is level with the office table. At the moment, the air cap 12 is screwed up to seal the air in the support frame, the sliding block 10 is moved to a proper position to be fixed, and the support rod 4 is sleeved on the sliding block 10 to lock the top plate.
