Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering drawing tools, and particularly relates to an auxiliary drawing tool for construction engineering design. Background Art

[0002] Engineering design is an activity of comprehensively analyzing and demonstrating the technical, economic, resource, environmental and other conditions required for a construction project according to the requirements of the project, and preparing the design documents of the construction project. Engineering design is a process in which people use scientific and technological knowledge and methods to purposefully create the concept and plan of engineering products, covering almost all fields of human activities. In the process of construction engineering design, drawing tools are often used.

[0003] When drawing, it is necessary to place the drawing paper on the drawing board to assist the designer in drawing. However, the fixing structure adopted by the existing drawing tools for fixing the drawing paper is relatively simple, and the fixing effect on the drawing paper is not very ideal. Especially in the case of fine drawing or long-term work, the drawing paper may move due to slight touch or air flow, affecting the drawing quality. At the same time, it is not convenient to adjust according to the specifications of the drawing paper. Users may need to prepare multiple drawing boards of different sizes to meet the needs of different projects, increasing the cost and storage space requirements. Moreover, it is not convenient to adjust the angle of the drawing board after the drawing paper is fixed, and there is not enough angle selection to meet the preferences of different users or the needs of specific tasks. This limits the creative freedom and comfort of users. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary drawing tool for construction engineering design, which has the advantages of flexible adjustment and efficient fixing of the drawing paper, can adapt to drawing papers of different widths, improves the application range of the tool, and the design of the clamping plate enables the drawing paper to be firmly fixed on the placing plate, avoiding the displacement problem that may occur during the drawing process. The support mechanism, through the combined design of the fixing plate, positioning slot and positioning rod, not only provides stable support for the placing plate, but also realizes rapid adjustment and locking of the angle.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an auxiliary drawing tool for construction engineering design, including a placing mechanism and a support mechanism rotatably arranged at the bottom thereof. A clamping mechanism is slidably connected to the front surface of the placing mechanism. The placing mechanism includes a vertically arranged placing plate:

[0006] The clamping mechanism includes U-shaped plates slidably arranged at the left and right ends of the front surface of the placement plate. Two clamping plates for fixing the drawing are slidably connected inside the two U-shaped plates close to the front surface of the placement plate. At the top of the inner walls of the two U-shaped plates, screw rod sleeves are fixedly connected. The two screw rod sleeves are slidably connected to the top of the front side of the placement plate. At the bottom of the inner walls of the two U-shaped plates, moving blocks are fixedly connected. The two moving blocks are slidably connected to the bottom of the front side of the placement plate.

[0007] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, a first installation groove and a second installation groove are respectively formed at the top and bottom of the front side of the placement plate. A bidirectional screw rod is rotatably connected inside the first installation groove. The surface of the bidirectional screw rod is threadedly connected to the inner walls of the two screw rod sleeves. A limiting rod is fixedly connected inside the second installation groove. The surface of the limiting rod is slidably connected to the inner walls of the two moving blocks. The bidirectional screw rod and the limiting rod are both horizontally arranged.

[0008] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, a worm gear is fixedly sleeved on the central surface of the bidirectional screw rod. A worm is meshed and connected to the top of the worm gear. The surface of the worm is rotatably connected to a mounting frame. The mounting frame is fixedly arranged at the central position of the top of the front side of the placement plate.

[0009] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, a plurality of L-shaped plates are equidistantly connected to the mutually remote sides of the two U-shaped plates. Each L-shaped plate is perpendicular to the U-shaped plate. A threaded rod is rotatably connected to each L-shaped plate. One end of the threaded rod extends to the front side outside the L-shaped plate and is fixedly connected to a knob.

[0010] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, a threaded sleeve is threadedly connected to the surface of each threaded rod. The end of the threaded sleeve remote from the threaded rod extends into the U-shaped plate and is rotatably connected thereto. The end of the threaded sleeve remote from the threaded rod is fixedly connected to the side of the clamping plate remote from the placement plate.

[0011] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, a guide rod is slidably connected to the inner wall of each threaded sleeve. A plurality of guide rods are fixedly arranged between the U-shaped plate and the L-shaped plate.

[0012] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, the support mechanism includes two support rods symmetrically and obliquely designed on the left and right. One ends of the tops of the two support rods are rotatably connected between the left and right ends of the rear side of the placement plate. The side of the two support rods remote from the bottom of the placement plate is fixedly connected to a support plate. The front side of the top of the support plate is rotatably connected to the bottom of the placement plate.

[0013] Preferably, as an auxiliary drawing tool for construction engineering design of the present utility model, fixed plates are fixedly connected to both the left and right sides of the top of the support plate. A plurality of positioning card slots are equidistantly arranged at the top of the two fixed plates. A positioning card rod is fixedly connected between the bottoms of the two support rods. The positioning card rod is engaged with the positioning card slots.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the worm is manually rotated to drive the worm gear to rotate. Since the worm gear is fixed on the bidirectional lead screw, the rotation of the worm gear will drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw will cause the two screw sleeves to move in opposite directions, so that the two U-shaped plates will move inwards or outwards, thereby adjusting the position of the clamping plate to clamp or release the drawing.

[0016] 2. In the present utility model, the angle of the placement plate is changed by manually adjusting the positions of the support rod and the support plate. Since the support rod and the support plate are rotatably connected to the placement plate, this design allows the placement plate to rotate freely within a certain range. When the user finds a suitable angle, the positioning card rod can be inserted into the corresponding positioning card slot on the fixed plate to lock the angle of the placement plate. The engagement design of the positioning card rod and the positioning card slot ensures that the placement plate remains stable at the adjusted angle and will not change the angle due to external vibration or slight touch.

Detailed implementation manner

[0024] Please refer to Figures 1-6 , an auxiliary drawing tool for construction engineering design, including a placement mechanism 100 and a support mechanism 200 rotatably arranged at its bottom. A clamping mechanism 300 is slidably connected to the front surface of the placement mechanism 100. The placement mechanism 100 includes a vertically arranged placement plate 101:

[0025] The placement mechanism 100 serves as the foundation of the entire drawing tool. It provides a stable working platform. The placement plate 101 is vertically arranged, providing a flat surface for the drawing paper, ensuring accuracy and stability during drawing. The support mechanism 200 is rotatably arranged at the bottom of the placement mechanism 100. The support mechanism 200 can flexibly adjust the angle of the drawing board, which is very important for different drawing postures and viewing angles, and can improve the comfort and efficiency of drawing.

[0026] Furthermore, the clamping mechanism 300 includes U-shaped plates 301 slidably arranged at the left and right ends of the front surface of the placement plate 101. Two U-shaped plates 301 are slidably connected to the inside of the front surface of the placement plate 101 near the front surface of the placement plate 101 with a clamping plate 302 for fixing the drawing paper. The top inner walls of the two U-shaped plates 301 are fixedly connected with lead screw sleeves 303. The two lead screw sleeves 303 are slidably connected to the top of the front side of the placement plate 101. The bottom inner walls of the two U-shaped plates 301 are fixedly connected with moving blocks 307. The two moving blocks 307 are slidably connected to the bottom of the front side of the placement plate 101.

[0027] The U-shaped plate 301 can slide left and right on the front surface of the placement plate 101, which means it can adapt to drawing papers of different widths, improving the application range of the tool. The design of the clamping plate 302 enables the drawing paper to be firmly fixed on the placement plate 101, avoiding displacement problems that may occur during the drawing process.

[0028] Further, a first mounting groove 102 and a second mounting groove 103 are respectively formed at the top and bottom of the front side of the placing plate 101. A bidirectional lead screw 304 is rotatably connected inside the first mounting groove 102. The surface of the bidirectional lead screw 304 is threadedly connected to the inner walls of two lead screw sleeves 303. A limiting rod 308 is fixedly connected inside the second mounting groove 103. The surface of the limiting rod 308 is slidably connected to the inner walls of two moving blocks 307. Both the bidirectional lead screw 304 and the limiting rod 308 are horizontally arranged.

[0029] By rotating the bidirectional lead screw 304, the distance between the two U-shaped plates 301 can be adjusted, and then the position of the clamping plate 302 can be adjusted to clamp or release drawings of different sizes. This adjustment method is not only simple to operate but also can provide sufficient clamping force to ensure that the drawing remains stable during the drawing process. The function of the limiting rod 308 is to serve as a guide to ensure that the moving block 307 (together with the U-shaped plate 301) moves in a straight line and prevent them from deflecting when the bidirectional lead screw 304 rotates. This helps to maintain the stability of the clamping mechanism 300 and ensure the fixing effect of the drawing.

[0030] Further, a worm gear 305 is fixedly sleeved on the central surface of the bidirectional lead screw 304. A worm 306 is meshed with the top of the worm gear 305. The surface of the worm 306 is rotatably connected to a mounting bracket 104. The mounting bracket 104 is fixedly arranged at the center of the top of the front side of the placing plate 101.

[0031] The user can drive the rotation of the worm gear 305 by manually rotating the worm 306. Since the worm gear 305 is fixed on the bidirectional lead screw 304, the rotation of the worm gear 305 will drive the rotation of the bidirectional lead screw 304. The rotation of the bidirectional lead screw 304 will cause the two lead screw sleeves 303 to move in opposite directions, so that the two U-shaped plates 301 will move inwards or outwards, thereby adjusting the position of the clamping plate 302 to clamp or release the drawing.

[0032] Further, a plurality of L-shaped plates 309 are equidistantly connected to the mutually remote sides of the two U-shaped plates 301. Each L-shaped plate 309 is perpendicular to the U-shaped plate 301. A threaded rod 311 is rotatably connected to each L-shaped plate 309. One end of the threaded rod 311 extends to the front side outside the L-shaped plate 309 and is fixedly connected to a knob 312.

[0033] Further, a threaded sleeve 310 is threadedly connected to the surface of each threaded rod 311. The end of the threaded sleeve 310 remote from the threaded rod 311 extends into the U-shaped plate 301 and is rotatably connected thereto. The end of the threaded sleeve 310 remote from the threaded rod 311 is fixedly connected to the side of the clamping plate 302 remote from the placing plate 101.

[0034] When it is necessary to clamp the drawing, the user can drive the threaded rod 311 to rotate by rotating the knob 312. Since the threaded rod 311 is threadedly connected to the threaded sleeve 310, rotating the threaded rod 311 will cause the threaded sleeve 310 to move axially. The movement of the threaded sleeve 310 will drive the clamping plate 302 to move inward, gradually pressing the drawing. In this way, the user can precisely control the clamping force to ensure that the drawing is firmly fixed between the U-shaped plates 301.

[0035] Furthermore, a guide rod 313 is slidably connected to the inner wall of each threaded sleeve 310, and a plurality of guide rods 313 are fixedly arranged between the U-shaped plate 301 and the L-shaped plate 309.

[0036] During the movement, the guide rod 313 plays a key guiding role. The guide rod 313 is fixed between the U-shaped plate 301 and the L-shaped plate 309, ensuring that the threaded sleeve 310 always moves in a straight line during movement and avoiding lateral deviation.

[0037] Furthermore, the support mechanism 200 includes two support rods 201 designed to be symmetrically inclined left and right. One end of the top of the two support rods 201 is rotatably connected between the left and right ends of the rear side of the placement plate 101. One side of the bottom of the two support rods 201 away from the placement plate 101 is fixedly connected with a support plate 202, and the front side of the top of the support plate 202 is rotatably connected to the bottom of the placement plate 101.

[0038] The user can change the angle of the placement plate 101 by manually adjusting the positions of the support rods 201 and the support plate 202. Since the support rods 201 and the support plate 202 are rotatably connected to the placement plate 101, this design allows the placement plate 101 to rotate freely within a certain range. The inclined design of the support rods 201 ensures that the placement plate 101 can remain stable at different angles and will not lose balance due to angle changes.

[0039] Furthermore, fixing plates 203 are fixedly connected to the left and right sides of the top of the support plate 202. A plurality of positioning card slots 204 are equidistantly opened at the top of the two fixing plates 203. A positioning card rod 205 is fixedly connected between the bottoms of the two support rods 201, and the positioning card rod 205 is mutually clamped with the positioning card slots 204.

[0040] The user can change the angle of the placement plate 101 by manually adjusting the positions of the support rod 201 and the support plate 202. Since both the support rod 201 and the support plate 202 are rotatably connected to the placement plate 101, this design allows the placement plate 101 to rotate freely within a certain range. When the user finds a suitable angle, the positioning latch 205 can be inserted into the corresponding positioning slot 204 on the fixed plate 203 to lock the angle of the placement plate 101. The latching design of the positioning latch 205 and the positioning slot 204 ensures that the placement plate 101 remains stable at the adjusted angle and will not change the angle due to external vibration or slight touch.

[0041] Through the combined design of the fixed plate 203, the positioning slot 204, and the positioning latch 205, the support mechanism 200 not only provides stable support for the placement plate 101 but also realizes rapid adjustment and locking of the angle. This design not only improves the comfort and efficiency of drawing but also ensures the stability and reliability of the entire drawing tool. Through the ingenious combination of the support rod 201 and the support plate 202, the tool can perform excellently in different usage scenarios and meet the diverse needs of users.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
