Description

Technical Field

[0001] This utility model relates to a drawing tool, and more particularly to an architectural design drawing device. Background Technology

[0002] In the field of architecture, architectural drawing is a commonly used design tool. Different drawings are required at different stages of architectural design. For example, in architectural design exams, it is often necessary to place an A2 drawing board directly on the table. However, the drawing board can only be laid flat, and prolonged periods of drawing at the desk are physically demanding. Furthermore, the drawing tools are numerous and difficult to store. The drawing scenarios at construction sites or outdoor design locations are often complex, which greatly interferes with the quality of the drawings.

[0003] Existing technologies can improve the drawing environment and thus improve drawing quality by setting up a simple drawing space or by using a fixed bracket to fix the drawing board.

[0004] However, the overall structure of the drawing support frame is complex and bulky, making it impossible to carry around. It also has many parts, making the assembly process cumbersome and difficult to operate. Utility Model Content

[0005] This utility model provides an architectural design drawing device that solves the problems of existing drawing supports being unportable and having a cumbersome and difficult-to-operate setup process.

[0006] This utility model provides an architectural design drawing device, including a first box and a second box that are hinged together. The first box and the second box are rotatable between a folded position and an unfolded position around their hinged sides. When the first box and the second box are in the folded position, the outer surfaces of the first box and the second box face away from each other. When the first box and the second box are in the unfolded position, the outer surfaces of the first box and the second box are on the same plane and form a drawing platform.

[0007] It also includes a support assembly, which includes a first support frame and a second support frame. The first support frame is connected to the first housing and is located on the side of the first housing opposite to the drawing platform, and the second support frame is connected to the second housing and is located on the side of the second housing opposite to the drawing platform.

[0008] Both the first and second support frames can rotate between the storage position and the support position around the hinged side under external force.

[0009] The storage position is configured such that both the first and second support frames are parallel to the drawing platform. The support position is configured such that at least a portion of the first and second support frames is perpendicular to the drawing platform, thereby supporting the drawing platform on the receiving surface.

[0010] This utility model's architectural design drawing device has a foldable function, which greatly reduces the size of the entire drawing device and makes it easy to carry. Furthermore, the outer surfaces of the first and second boxes, when unfolded, form a drawing platform, making the drawing device suitable for various drawing scenarios and helping to improve the drawing environment in harsh working conditions. In addition, this utility model's architectural design drawing device has a retractable first and second support frame, which adds a drawing support function to the architectural design drawing device without increasing the overall size, making it convenient for the drafter to use in low and uneven environments. The structure is simple and the operation is convenient.

[0011] Optionally, both the first and second support frames are U-shaped. The first and second support frames are symmetrically arranged along the hinged sides.

[0012] The two ends of the first support frame are rotatably connected to the first and second sides of the first housing adjacent to the hinged side, respectively. The two ends of the second support frame are rotatably connected to the third and fourth sides of the second housing adjacent to the hinged side, respectively.

[0013] U-shaped slides are provided on the first, second, third, and fourth sides, and both ends of the first and second support frames can move along the corresponding U-shaped slides.

[0014] When in the storage position, the two ends of the first support frame and the two ends of the second support frame are respectively located at the end of the corresponding U-shaped slide near the hinge side.

[0015] When in the supported position, the two ends of the first support frame and the two ends of the second support frame are respectively located at the ends of the corresponding U-shaped slides away from the hinged side.

[0016] This utility model embodiment uses a U-shaped slide rail to allow both the first and second support frames to move along the corresponding U-shaped slide rail. It cleverly utilizes spatial transformation to allow the first and second support frames to be flexibly stored and unfolded within a limited space. The entire structure is simple to operate and lightweight.

[0067] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0068] This utility model provides an architectural design and drawing device 100, please refer to [link / reference]. Figures 1-5 It includes a hinged first housing 100A and a second housing 100B, which are capable of rotating between a folded position and an unfolded position about their hinged sides. Figure 1 As shown, when the first box 100A and the second box 100B are in the folded position, the outer surface of the first box 100A is opposite to the outer surface of the second box 100B, as... Figure 2 and Figure 3 As shown, when the first box 100A and the second box 100B are in the unfolded position, the outer surface of the first box 100A and the outer surface of the second box 100B are on the same plane and form a drawing platform.

[0069] like Figures 2-5As shown, the architectural design drawing device 100 also includes a support assembly, which includes a first support frame 121 and a second support frame 122. The first support frame 121 is connected to the first housing 100A and is located on the side of the first housing 100A opposite to the drawing platform. The second support frame 122 is connected to the second housing 100B and is located on the side of the second housing 100B opposite to the drawing platform.

[0070] Both the first support frame 121 and the second support frame 122 can be driven by external force to retract into their storage positions around the hinged side (e.g., Figure 2 (as shown) and support locations (such as) Figure 3 Rotate between (as shown).

[0071] The storage position is configured such that the first support frame 121 and the second support frame 122 are both parallel to the drawing platform. The support position is configured such that at least a portion of the first support frame 121 and at least a portion of the second support frame 122 are perpendicular to the drawing platform, so as to support the drawing platform on the receiving surface.

[0072] The architectural design drawing device 100 of this utility model has a foldable function, which greatly reduces the size of the entire drawing device and makes it easy to carry. Furthermore, the outer surfaces of the first box 100A and the second box 100B after unfolding form a drawing platform, making the drawing device suitable for various drawing scenarios and helping to improve the drawing environment in harsh working conditions. Furthermore, the architectural design drawing device 100 of this utility model has a retractable first support frame 121 and a second support frame 122, which adds a drawing support function to the architectural design drawing device 100 without increasing the overall size, making it convenient for the drawer to use in low and uneven environments. The structure is simple and the operation is convenient.

[0073] In one implementation, such as Figure 1 As shown, the edges of the first box 100A and the second box 100B are provided with a carrying rack (or handle) for easy lifting and gripping.

[0074] In one implementation, such as Figure 4 As shown, the first housing 100A and the second housing 100B have mounting grooves 131 on their surfaces away from the drawing platform, and the first support frame 121 and the second support frame 122 are embedded in the mounting grooves 131 when in the storage position.

[0075] Furthermore, the shape and number of the first support frame 121 and the second support frame 122 are not limited. For example, they can be rod-shaped, ring-shaped, rectangular ring-shaped, etc. As long as they can rotate between the above-mentioned storage position and support position and can support the first box 100A and the second box 100B on the receiving surface when in the support position, they do not depart from the scope of the present utility model embodiment.

[0076] In one implementation, please refer to Figure 4 and Figure 5 Both the first support frame 121 and the second support frame 122 are U-shaped. The first support frame 121 and the second support frame 122 are symmetrically arranged along the hinged side.

[0077] The two ends of the first support frame 121 are respectively rotatably connected to a first side and a second side adjacent to the hinged side in the first housing 100A. The first side and the second side can be understood as... Figure 4 The two short sides of the first housing 100A and the two ends of the second support frame 122 are respectively rotatably connected to the third and fourth sides of the second housing 100B adjacent to the hinged sides. The third and fourth sides can be understood as... Figure 4 The two short sides of the second box body 100B.

[0078] like Figure 6 As shown, U-shaped slides 120 are provided on the first side, the second side, the third side and the fourth side, and the two ends of the first support frame 121 and the two ends of the second support frame 122 can move along the corresponding U-shaped slides 120.

[0079] When in storage, such as Figure 2 As shown, the two ends of the first support frame 121 and the two ends of the second support frame 122 are respectively located at the end of the corresponding U-shaped slide 120 near the hinge side.

[0080] When in a support position, such as Figure 3 As shown, the two ends of the first support frame 121 and the two ends of the second support frame 122 are respectively located at the ends of the corresponding U-shaped slides 120 away from the hinge.

[0081] In one embodiment, the U-shaped slide 120 is located within the mounting groove 131. In one exemplary embodiment, the U-shaped slide 120 is formed by opening a hole in one side wall of the mounting groove 131. In other alternative embodiments, the U-shaped slide 120 may also be a structure independent of the mounting groove 131.

[0082] In one implementation, such as Figures 6-8 As shown, taking one end of the first support frame 121 as an example, the support process of the support assembly is explained. The U-shaped slide 120 includes a lower slot 120A, a horizontal slot 120B, and a lower slot 120C that are interconnected. When the first support frame 121 is in the retracted state, its end is located in the lower slot 120A. Figure 6 Rotate the first support frame 121 in the direction indicated by the arrow and lift it upward so that its end enters the horizontal slot 120B, along... Figure 7Pulling in the direction indicated by the arrow causes the end of the first support frame 121 to slide along the horizontal slot 120B toward the lower slot 120C until it falls into the lower slot 120C, as shown. Figure 8 As shown, at this time, the first support frame 121 is in the supported position. Those skilled in the art will understand that the working principle of the other end of the first support frame 121 and the second support frame 122 is similar to the above process, and will not be repeated here.

[0083] This embodiment of the utility model sets up a U-shaped slide 120 so that both the first support frame 121 and the second support frame 122 can move along the corresponding U-shaped slide 120. It cleverly utilizes spatial transformation so that the first support frame 121 and the second support frame 122 can be flexibly stored and unfolded in a limited space. The whole structure is simple to operate and lightweight.

[0084] Furthermore, in one implementation, such as Figure 8 As shown, the first support frame 121 has a double-layer structure, including a first support body 1211 and a second support body 1212 arranged side by side, which are connected together by a connector 1213. The double-layer structure has a larger contact area with the ground and provides more stable support. In other alternative embodiments, the structure of the first support frame 121 can be other structures, as long as it is a structure with a certain degree of support, it does not depart from the scope of the present utility model embodiment.

[0085] Please see Figure 9 and Figure 10 In one embodiment, in order for the first support frame 121 and the second support frame 122 to rotate about their respective ends to disengage from the storage position, at least a portion of the sidewall 1311 of the mounting groove 131 is inclined. For example, the lower half of the sidewall 1311 of the mounting groove 131 is vertical to tightly engage the support frame, and the upper half of the sidewall 1311 is inclined to prevent interference with the first support frame 121 and / or the second support frame 122 during rotation. The purpose is also that when the support assembly is in the storage position, it cannot be rotated directly; instead, the support assembly needs to be lifted first for initial locking. Furthermore, in one embodiment, magnets can be provided in the mounting groove 131, on the first support frame 121, and on the second support frame 122. Through magnetic attraction, the support assembly will not detach from the mounting groove 131 without external force.

[0086] For further details, please see Figures 11-13 and combined Figures 6-8The support assembly further includes a first rotating shaft 123 and a first slider 125. The first slider 125 is disposed within the U-shaped slide rail 120 of the first housing 100A, and has a first shaft hole 1251 and a first limiting arc hole 1252 concentrically arranged on the first slider 125. The side wall of the first rotating shaft 123 is provided with a first arc-shaped boss 1230. At least one end of the first support frame 121 passes through the first rotating shaft 123 and is inserted into the first slider 125 to follow the first slider 125 as it moves along the corresponding U-shaped slide rail 120. The first rotating shaft 123 is located within the first shaft hole 1251, and the first arc-shaped boss 1230 is located within the first limiting arc hole 1252, thereby limiting the first support frame 121 between the supporting position and the storage position.

[0087] Those skilled in the art will understand that the second support frame 122 can also be connected to the U-shaped slide rail via a structure similar to the one described above. Specifically, for example, the second slider is disposed within the U-shaped slide rail of the second housing, and the second slider has a second shaft hole and a second limiting arc hole arranged concentrically. The side wall of the second rotating shaft is provided with a second arc-shaped boss, and at least one end of the second support frame passes through the second rotating shaft and is disposed within the second slider to follow the second slider along the corresponding U-shaped slide rail. The second rotating shaft is located within the second shaft hole, and the second arc-shaped boss is located within the second limiting arc hole, thus limiting the second support frame between the supporting position and the stored position. Through the above structure, this embodiment of the present invention can limit the first and second support frames when they are in the supporting position, improving the stability of the support.

[0088] Furthermore, in one implementation, please refer to Figures 11-13 and combined Figures 6-8 It is understood that the bottom of the first slider 125 is provided with a first positioning hole 1253, the side wall of the first rotating shaft 123 is provided with a first locking hole 1231, and the end of the U-shaped slide 120 corresponding to the first slider 125 away from the hinge is provided with a first positioning rod 1201. The first positioning rod 1201 can pass through the first positioning hole 1253 and the first locking hole 1231 when the first support frame 121 is in the support position, so as to position the first support frame 121 in the support position.

[0089] Similarly, the second slider can also use a similar structure to position the second support frame 122. Specifically, the bottom of the second slider is provided with a second positioning hole, the side wall of the second rotating shaft is provided with a second locking hole, and the end of the U-shaped slide corresponding to the second slider away from the hinge is provided with a second positioning rod. The second positioning rod can pass through the second positioning hole and the second locking hole when the second support frame is in the supported position, so as to position the second support frame in the supported position. Through the above structure, this embodiment of the utility model further improves the stability of the first support frame and the second support frame when they are in the supported position.

[0090] In one implementation, such as Figure 12 As shown, the first housing 100A includes a first box plate 103 and a first top plate 101, with the side of the first top plate 101 connected to the edge of the first box plate 103. The second housing 100B includes a second box plate 104 and a second top plate 102, with the side of the second top plate 102 connected to the edge of the second box plate 104. When the first housing 100A and the second housing 100B are in the unfolded position, the surface of the second top plate 102 away from the second box plate 104 serves as the outer surface of the second housing 100B. This structure can be understood as follows: in this embodiment, the outer surfaces of the first top plate 101 and the second top plate 102 form a drawing platform in the unfolded state. In one embodiment, the surfaces of the first box plate 103 and the second box plate 104 away from the drawing platform are both provided with anti-slip pads.

[0091] Furthermore, a foldable first inclined bracket 113 is provided between the first top plate 101 and the first box plate 103, and a foldable second inclined bracket 114 is provided between the second top plate 102 and the second box plate 104, so as to support the drawing platform formed by the first top plate 101 and the second top plate 102 to be inclined to the first box plate 103 and the second box plate 104.

[0092] Furthermore, in one implementation, please refer to Figure 14 and Figure 15 The architectural design and drawing device 100 also includes a first adjusting screw 115 and a first adjusting block 117. The surface of the first box plate 103 near the first top plate 101 is provided with a first groove 1031. The two ends of the first adjusting screw 115 are connected to the side wall of the first groove 1031 and its extension direction is consistent with the folding direction of the first tilting bracket 113. The first adjusting block 117 is engaged with the first adjusting screw 115 so as to slide along the extension direction of the first adjusting screw 115 under the drive of external force.
