Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drawing frame technology, specifically relating to a retractable general-purpose drawing frame. Background Technology
[0002] A map board is a two-dimensional tool used to display and manage map information. It is commonly used in education, planning, navigation, or presentation. It can be physical or electronic. Map boards can be used to display geographical information, transportation routes, administrative divisions, etc.
[0003] Traditional map boards present many inconveniences in field operations. Although they are powerful in displaying and conveying geographical information, they are difficult to meet professional needs in actual use, especially in complex terrain and changeable weather conditions. Paper map boards are easily affected by natural conditions such as moisture, wind and damage, which limits their service life and effectiveness in the field. Utility Model Content
[0004] The purpose of this utility model is to provide a retractable and comprehensive map frame to solve the problem mentioned in the background art that existing map boards are inconvenient for field map operations.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A scalable general-purpose drawing frame, comprising:
[0007] Mounting base;
[0008] A support frame, which is mounted on the bottom end of the mounting base;
[0009] A support mechanism is fixedly connected to the top of the mounting base. The support mechanism includes a mounting rod, a rotating sleeve, and a support rod. The rotating sleeve is fitted around the mounting rod, and the support rod is rotatably connected to the outside of the rotating sleeve. A telescopic sleeve is fitted around the support rod, and a hinge rod is rotatably connected to the outside of the telescopic sleeve.
[0010] Preferably, multiple support rods are rotatably connected to the outside of the rotating sleeve, the telescopic sleeve is slidably connected to the outside of the support rod, and the hinge rod is sleeved on the outside of the mounting rod through a collar.
[0011] Preferably, the top of the support mechanism is provided with a drawing board mechanism, and the outside of the support mechanism is equipped with a hook mechanism.
[0012] Preferably, the drawing board mechanism includes a first drawing board module, a sleeve ring, and a movable shaft. The sleeve ring is provided on the outer side wall of the first drawing board module, the movable shaft is inserted inside the sleeve ring, and a second drawing board module is fixedly connected to one side of the movable shaft.
[0013] Preferably, the movable shaft is rotatably connected inside the sleeve ring, and the first drawing board module and the second drawing board module have the same appearance and structure.
[0014] Preferably, the hook mechanism includes a mounting plate, fixing bolts, and a hanging hook. The mounting plate is provided with fixing bolts on the outside and a hanging hook is installed inside the mounting plate.
[0015] Preferably, the mounting plate is fixedly mounted on the outside of one side of the mounting base by fixing bolts.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This utility model, through the installation rod, rotating sleeve, support rod, and support frame, enables the map board mechanism to adopt an unfoldable design. The support rod can be flexibly unfolded through the rotational connection between the support rod and the rotating sleeve, and the rotational cooperation between the hinge rod and the telescopic sleeve. The unfolded support rod can stably support the map board mechanism, allowing it to be laid horizontally on top for easy map display and use. The map board surface is covered with a PVC waterproof membrane, which combines light transmission and waterproofing, ensuring clear map visibility while effectively preventing rain in outdoor environments. The specially treated membrane surface allows for direct annotation with ballpoint pens or gel pens, meeting the real-time marking needs of field workers.
[0018] 2. This utility model, through the arrangement of a first drawing board module, a sleeve ring, a movable shaft, and a second drawing board module, enables the drawing board to adopt a one-way folding design. After the movable shaft is inserted into the sleeve ring, the first drawing board module is allowed to rotate counterclockwise relative to the second drawing board module. However, due to its tight clearance fit, it cannot rotate clockwise. This structure allows the drawing board to bend and roll up to one side only, ensuring that it remains stable and flat after unfolding, avoiding accidental folding, and facilitating stable placement during use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1:
[0027] Please see Figures 1-5 As shown, a scalable general-purpose drawing frame includes:
[0028] Mounting base 1;
[0029] Support frame 2 is installed at the bottom end of mounting base 1;
[0030] Support mechanism 3 is fixedly connected to the top of mounting base 1. Support mechanism 3 includes mounting rod 301, rotating sleeve 302 and support rod 303. Rotating sleeve 302 is sleeved on the outside of mounting rod 301. Support rod 303 is rotatably connected to the outside of rotating sleeve 302. Telescopic sleeve 304 is sleeved on the outside of support rod 303. Hinge rod 305 is rotatably connected to the outside of telescopic sleeve 304. Multiple support rods 303 are rotatably connected to the outside of rotating sleeve 302. Telescopic sleeve 304 is slidably connected to the outside of support rod 303. Hinge rod 305 is sleeved on the outside of mounting rod 301 through a collar. Drawing plate mechanism 4 is provided at the top of support mechanism 3. Hook mechanism 5 is installed on the outside of support mechanism 3.
[0031] Specifically, the support rod 303 can be unfolded or folded through the rotational connection between the support rod 303 and the rotating sleeve 302, and the rotation between the hinge rod 305 and the telescopic sleeve 304.
[0032] As can be seen from the above, when the drawing board mechanism 4 is unfolded, the support rod 303 can be unfolded by rotating the support rod 303 on the rotating sleeve 302 and rotating the hinge rod 305 and the telescopic sleeve 304. After the support rod 303 is unfolded, the drawing board mechanism 4 can be laid flat on the top of the support rod 303, so that the drawing board can be used. Moreover, the PVC waterproof membrane set on the drawing board mechanism 4 does not affect the transparency and visibility of the map.
[0033] Example 2:
[0034] refer to Figure 3 and Figure 5 As shown, the drawing board mechanism 4 includes a first drawing board module 401, a sleeve ring 402, and a movable shaft 403. The sleeve ring 402 is provided on the outer wall of the first drawing board module 401, and the movable shaft 403 is inserted inside the sleeve ring 402. A second drawing board module 404 is fixedly connected to one side of the movable shaft 403. The movable shaft 403 is rotatably connected inside the sleeve ring 402. The first drawing board module 401 and the second drawing board module 404 have the same appearance and structure. The hook mechanism 5 includes a mounting plate 501, a fixing bolt 502, and a hanging hook 503. The fixing bolt 502 is provided on the outside of the mounting plate 501, and the hanging hook 503 is installed inside the mounting plate 501. The mounting plate 501 is fixedly installed on one side of the mounting base 1 by the fixing bolt 502.
[0035] Specifically, by installing the hook 503 on the mounting plate 501, the work tools can be hung on it. The surface of the drawing board mechanism 4 has a layer of PVC waterproof membrane, which can block rainwater from the map on the drawing board.
[0036] As can be seen from the above, when the movable shaft 403 is inserted inside the sleeve ring 402, the first drawing board module 401 can rotate counterclockwise outside the second drawing board module 404. The gap between the first drawing board module 401 and the second drawing board module 404 is small, so the first drawing board module 401 cannot rotate clockwise on the second drawing board module 404. Thus, the drawing board can only be bent and rolled up on one side, so that the drawing board cannot be bent after being unfolded and placed, which facilitates the use of the drawing board.
