DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown: A construction project progress recording and planning device includes a writing board 1, which is used to write and record the current progress of the project. The writing board 1 is installed on a lifting mechanism 3 with a hinge 2, so that it can be lifted and lowered by the lifting mechanism 3 to adjust its own height. At the same time, it is also hingedly combined with the hinge 2 by hinge mechanisms 4 on the left and right sides, so that it can be rotated by the hinge mechanism 4 to adjust its own angle.

[0025] Furthermore, the above-mentioned hinge mechanism 4 includes two long arms, which are respectively a front long arm 401 and a rear long arm 402, and the writing board 1 and the hinge 2 are equipped with hinge blocks designed in an isosceles right triangle, wherein the hinge block of the writing board 1 is hinge block I 403, and the hinge block of the hinge 2 is hinge block II 404, the front long arm 401 and the rear long arm 402 are arranged in parallel through the hinge blocks, and are also supported by the support arm 405 of the hinge 2; when the hinge block rotates, the movement of the two long arms can make the writing board 1 rotate relative to the hinge 2, and the writing board 1 can be switched between an upright or inclined state.

[0026] Specifically, Figure 3 , Figure 4 As shown, the hinge block I 403 has a bottom angle which is fixed to the writing board 1 by a fastener, while the hinge block II 404 is directly hinged to the hinge table 2 at a right angle. The ends of the front long arm 401 and the rear long arm 402 are correspondingly hinged to the positions of the other two corners of the hinge block I 403 and the hinge block II 404, thereby realizing parallel arrangement with each other.

[0027] Specifically, in order to achieve mutual fixation between the hinge block Ⅰ403 and the writing board 1, the bottom corner of the hinge block Ⅰ403 used for combination with the writing board 1 can also be formed with an extension section 413. The bottom corner and the extension section 413 are combined with the writing board 1 through a number of positioning holes, thereby preventing relative movement between the two.

[0028] Specifically, a supporter 407 locked with a short arm 417 is fixed to the middle section of the rear long arm 402 , and a support arm 405 swingably mounted on the rear side of the hinge platform 2 has its end hinged to the short arm 417 .

[0029] Furthermore, a stopper 406 is fixed at the hinge position of the hinge block II 404 corresponding to the side wall of the hinge table 2, and the stopper 406 itself forms an angle α, and the hinge block II 404 is limited to rotate within the angle α. Of course, the angle α is preferably 135°. If so, the writing board 1 is tilted at an angle of 45°, and the technician's elbow can lean on the writing board 1 at the most suitable angle, so that writing and recording work can be carried out more easily.

[0030] Specifically, a nylon rubber ring (not shown in the figure) can also be installed at the hinge position between the hinge block II 404 and the hinge platform 2. The nylon rubber ring allows greater friction between the hinge block II 404 and the hinge platform 2. When the hinge block II 404 is not subjected to external force, the hinge mechanism 4 cannot move on its own, thereby avoiding the technical problem of the writing board 1 swaying for no reason under normal use.

[0031] Furthermore, the lifting mechanism 3 is specifically a cross-scissor lifting platform, and the lifting plate 301 that can be driven to move up and down is used to fix and install the hinge platform 2.

[0032] Specifically, the lifting plate 301 and the base 302 of the above-mentioned scissor-type lifting platform are both provided with sliding grooves on both sides, and two of the several connecting rods 303 that are staggered and hinged to each other can cooperate with the corresponding sliding grooves. Among them, the connecting rod 303 that cooperates with the sliding groove of the base 302 is interconnected with a drag block 304 in the base 302. When the drag block 304 is driven by a motor (not shown in the figure) to slide horizontally, the connecting rod 303 can drive other connecting rods 303 to move synchronously, thereby controlling the up and down displacement of the lifting plate 301, and then adjusting the height of the writing board 1 itself (the principle of the scissor-type lifting platform is a prior art and will not be elaborated in this article).

[0033] As mentioned above, the background technology refers to a recording and planning device, in which the writing board is set in a vertical state. When the technician writes, the elbow is suspended in the air, which easily causes fatigue. Compared with this design, the writing board can adjust its own angle to make itself tilted at 45°. If this is done, the technician's elbow can lean on the writing board, thereby reducing fatigue and allowing longer writing and recording work; of course, according to different actual operating conditions, the limiter can also be disassembled and replaced, so that the writing board can be tilted at other different angles to meet the needs of most technicians.

[0034] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
