[0027] This utility model provides a technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 3 A drawing clamping device for architectural engineering design includes a placement frame 3, a fixing mechanism 1 is provided on the rear side of the placement frame 3, and a clamping mechanism 2 is provided on the front side of the placement frame 3.

[0030] The fixing mechanism 1 includes a suction component 11, a connecting component 12, and a suction component 13. The suction component 11 is located on the rear side of the placement frame 3, the connecting component 12 is located on the rear side of the suction component 11, and the suction component 13 is located inside the connecting component 12.

[0031] The suction assembly 11 includes a fixed cover 1101, which is fixedly connected to the rear side of the placement rack 3. A suction slit 1102 is provided inside the placement rack 3 at the front side of the fixed cover 1101. The connecting assembly 12 includes a connecting pipe 1201, which is fixedly connected to the rear side of the fixed cover 1101. An air pump 1202 is fixedly connected to the bottom of the connecting pipe 1201. A fixing rod 1203 is fixedly connected to the front side of the air pump 1202 and is fixedly connected to the rear side of the placement rack 3. The suction assembly 13... The device includes a suction plate 1301, which is slidably connected to the inner ring of the suction cylinder 1202. The outer ring of the suction plate 1301 is in contact with the inner ring of the suction cylinder 1202. A compression spring 1302 is fixedly connected to the top of the suction plate 1301 and is fixedly connected to the top of the suction cylinder 1202. A telescopic slide rod 1303 is fixedly connected to the bottom of the suction plate 1301 and is slidably connected to the bottom of the suction cylinder 1202. A pull rod 1304 is fixedly connected to the bottom of the telescopic slide rod 1303.

[0032] Furthermore, the staff only needs to place the design drawing on the front side of the placement rack 3, press the pull rod 1304 upwards, and then place the drawing on the front side of the placement rack 3. The negative pressure generated by the suction seam 1102 will adsorb the drawing and fix it on the front side of the placement rack 3. This increases the stability of the drawing on the front side of the placement rack 3 when in use, making it easier for the staff to draw the drawing later. At the same time, the device adsorbs the drawing through the negative pressure generated inside the device, and can fix the drawing without the intervention of external materials. The operation is simple and convenient for the staff to use.

[0033] Example 2

[0034] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 Furthermore, based on Embodiment 1, the clamping mechanism 2 includes a moving component 21, a positioning component 22, and a resetting component 23. The moving component 21 is disposed on the front side of the placement frame 3, the positioning component 22 is disposed on the rear side of the moving component 21, and the resetting component 23 is disposed on the front side of the moving component 21.

[0035] The moving component 21 includes a track cylinder 2101, which is fixedly connected to the upper and lower sides of the placement frame 3. A slide cylinder 2102 is slidably connected inside the track cylinder 2101. A fixed slide rod 2103 is slidably connected to the inner ring of the slide cylinder 2102. The fixed slide rod 2103 is fixedly connected to the left and right sides inside the track cylinder 2101. A movable slide rod 2104 is fixedly connected to the front side of the slide cylinder 2102 and slidably connected to the front side of the track cylinder 2101. A moving frame 2105 is fixedly connected to the inner side of the movable slide rod 2104. The positioning component 22 includes a positioning plate 2201, which is disposed on the rear side of the moving frame 2105. The rear side of the positioning plate 2201 is fixedly connected to... A protrusion 2202 is attached, and a handle 2203 is fixedly connected to the front side of the positioning plate 2201. The handle 2203 is slidably connected to the front side of the movable frame 2105. The reset assembly 23 includes a fixed cylinder 2301, which is fixedly connected to the front side of the movable frame 2105. A slider 2302 is slidably connected inside the fixed cylinder 2301. A reset spring 2303 is fixedly connected to the front side of the slider 2302. The reset spring 2303 is fixedly connected to the front side of the fixed cylinder 2301. A connecting slide rod 2304 is fixedly connected to the rear side of the slider 2302. The connecting slide rod 2304 is slidably connected to the movable frame 2105 and is fixedly connected to the front side of the positioning plate 2201.

[0036] Furthermore, the operator only needs to move the positioning plates 2201 on the left and right sides to the left and right sides of the drawing, and then release the pull on the handle 2203. This allows the positioning plates 2201 to move backward and contact the front of the drawing through the protrusion 2202 to complete the positioning of the drawing. This further increases the stability of the drawing after it is placed on the front side of the placement rack 3. In the entire operation of clamping and fixing the drawing, the operator only needs to press the lever 1304 upward and move the handle 2203 outward to the inward side in two steps. The operation is simple.

[0037] In actual operation, when this device is used and the drawing needs to be placed, the operator first presses the pull rod 1304 upward. The pull rod 1304 moves upward, which drives the suction plate 1301 upward through the telescopic slide rod 1303. The suction plate 1301 moves upward and squeezes the air in the suction cylinder 1202 to be discharged through the suction slit 1102. Then the operator places the drawing in front of the placement rack 3 and releases the force on the pull rod 1304. At this time, the suction plate 1301 moves downward under the action of the compression spring 1302. At this time, the suction cylinder 1202 sucks in the outside air through the suction slit 1102. However, at this time, the drawing covers the front of the placement rack 3 and covers the suction slit 1102, which prevents the air in the suction cylinder 1202 from being replenished to balance the air pressure inside the suction cylinder 1202. This keeps the suction slit 1102 always holding the drawing in place, and the drawing placement process is completed.

[0038] Then, the staff pulls the handles 2203 on both sides forward, backward, and inward. The inward movement of the handles 2203 causes the positioning plates 2201 to move inward until the positioning plates 2201 on both sides are in position on the left and right sides of the drawing. Then, the gripping force on the handles 2203 is released. At this time, the slider 2302, under the action of the fixed cylinder 2301, drives the positioning plates 2201 to move backward through the connecting slider 2304. The positioning plates 2201 move backward and contact the front side of the drawing through the protrusion 2202 to complete the positioning of the left and right sides of the drawing. At this time, the fixing process of the drawing is completed.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
