Description

Technical Field

[0001] The utility model relates to the technical field of folding tables, in particular to a folding table with adjustable support angle. Background Art

[0002] Project cost is a part of civil engineering technology. It refers to the technology that uses economics, management, and civil engineering as theoretical foundations to estimate and summarize engineering design costs and expenditures from the perspective of construction engineering management. Project cost is the core of the overall construction process.

[0003] For the progress of a project, supervisors are often required to frequently inspect and record the construction. They usually carry recording devices to inspect various parts of the project, and record relevant progress and evaluation opinions during the inspection. Because of the need for mobile recording, a recording device usually consists of a cardboard and a paper clip. As long as there is a suitable support point, it can provide the recording needs. It is also the most common mobile recording device in the prior art. Although the use of this device is simple and practical, its writing space is limited. At present, there are some folding tables on the market that are easy to carry and have a large writing space, but the construction site environment is complex. The folding table is unstable when used on the construction site and is prone to shaking when writing. It is still limited by the site environment and is not conducive to recording. Utility Model Content

[0004] Therefore, the utility model provides a folding table with adjustable support angle, which can overcome the defects of limited writing space for handheld recording boards and unstable support of the folding table in the prior art.

[0005] In order to solve the above problems, the utility model provides a folding table with adjustable support angle, comprising a foldable recording board and a foldable support frame for supporting the recording board, the support frame comprising a folding support plate and a tightening mechanism, the folding support plate comprising a first support plate and a second support plate, one end of the first support plate is hinged to the recording board, and the other end is provided with a accommodating hole adapted to the second support plate, the accommodating hole has a fixed axis along its width direction, and the second support plate has a groove slidably matched with the fixed axis along its length direction, the tightening mechanism is located on the first support plate near the upper end of the accommodating hole, and the tightening mechanism can keep the second support plate and the first support plate relatively fixed in position.

[0006] In some embodiments, the clamping mechanism includes a fixed block fixedly connected to the first support plate, the fixed block having a through hole, the support column passing through the through hole and being able to slide axially along the through hole, the end of the support column away from the second support plate being sleeved with a spring, one end of the spring being connected to the support column, and the other end thereof being connected to the fixed block, the upper surface of the second support plate having a plurality of spaced bosses, and the end of the support column away from the spring being in abutment with the bosses.

[0007] In some embodiments, the recording board includes two hinged folding plates and fixing clips disposed at non-hinged ends of the folding plates.

[0008] In some embodiments, the upper surface of the folding plate has a buffer block, and the height of the buffer block is greater than the height of the fixing clip.

[0009] In some embodiments, the fixing clip has a hollow accommodating cavity, and the accommodating cavity has a sealing device to keep the accommodating cavity in a sealed state.

[0010] In some embodiments, the fixing clip further comprises a clamping portion, and the clamping portion comprises a rubber pad.

[0011] In some embodiments, the bottom surface of the folding plate has a hinge groove adapted to the folding support plate.

[0012] In some embodiments, there are limiting holes on both sides of the hinged gaps of the two folding plates, and the two protruding ends of the U-shaped limiting bolt are respectively inserted into the limiting holes of different folding plates.

[0013] The utility model provides a folding table with adjustable support angle. Two folding plates are hinged by hinged joints, which are convenient for folding and carrying, and the volume when carrying is reduced. The buffer block ensures that the two folding plates do not squeeze the fixed clamps clamped in the middle for fixing recording paper when folding. The two folding plates are fixed when the folding plates are spread in combination with the limit bolts. Then the folding support plates on both sides are pulled out, and the second support plate cooperates with the first support plate to form a triangular support to form a stable recording platform. It is convenient to install and record in a complex construction site environment, avoiding the problems of carrying a notebook in the prior art and the lack of a stable platform for convenient recording on the construction site. Fixed clamps are respectively arranged on the two folding plates, which can clamp and fix the used and unused recording papers respectively. In addition, a cavity for placing a recording pen is arranged on the inner side of the fixed clamp to avoid the pen carried alone from being easily lost. The second support plate slides in the groove through the fixed shaft to stretch according to the use needs, and then is positioned by pushing the boss into the position through the tightening mechanism to form a triangular stable support. The setting can be adjusted accordingly according to the flatness of the ground to better ensure the writing effect. BRIEF DESCRIPTION OF THE DRAWINGS
