Description

Technical Field

[0001] This utility model belongs to the technical field of drawing display stands, specifically relating to an engineering cost drawing display stand. Background Technology

[0002] Construction cost drawings refer to the drawings used in construction projects to prepare budgets, preliminary estimates, construction budgets and final accounts, as well as bills of quantities. Currently, when architectural design drawings are displayed, construction cost drawings are required to be placed on display stands.

[0003] However, traditional engineering cost drawing display stands have many limitations in structure and function. For example, most existing display stands use magnetic blocks to fix the drawings. Although magnetic blocks are relatively flexible, they are also prone to falling and being lost. In the long run, this often leads to situations where the engineering cost drawings cannot be fixed afterward. Furthermore, most existing display stands use fixed-size drawing fixing structures, making it difficult to adapt to engineering cost drawings of different sizes. In practical applications, due to the large number of engineering cost projects and the varying sizes of drawings, operators often need to change to different display stands or make complex adjustments to the existing ones to fit the drawing sizes. This not only increases the difficulty and workload of operation but also wastes a lot of time and energy. Utility Model Content

A mounting cover is fixedly connected to the end of the positioning rod away from the fixed block. An anti-slip pad is provided inside the mounting cover. The positioning structure also includes a burr sleeve fixedly connected to the outer wall of the rotating shaft. The anti-slip pad selectively fits against the outer wall of the burr sleeve.

[0012] In a preferred embodiment, a first protective sleeve is fixedly connected to the outer wall of the rotating disk, a second protective sleeve is sleeved on the outer wall of the first protective sleeve, the second protective sleeve is fixedly connected to the upright plate, a second spring is fixedly connected between the rotating disk and the upright plate, the second spring is sleeved on the outer wall of the telescopic rod, and the second spring is located inside the first protective sleeve and the second protective sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, through the setting of a fixing structure and a connecting structure, allows operators to view and process engineering cost drawings using this device. Operators can pull the corresponding upright plate according to the dimensions of the engineering cost drawings. After the upright plate is disengaged from the nearby fixing slot, the operator rotates the upright plate with the help of a rotating disc, causing the pin to move away from the fixing slot. Simultaneously, with the cooperation of other upright plates, pins, and fixing slots, the operator can flexibly pull a fixing block assembly of the same width as the engineering cost drawings using a single handle, thereby quickly fixing the engineering cost drawings. The remaining fixing blocks remain flexible and usable, enabling rapid and precise fixing of engineering cost drawings of different sizes. This feature gives the device wide applicability and greatly improves its efficiency and practicality.

[0015] This utility model, by setting a movable structure, allows the operator to quickly adjust the position of the fixed block and connecting block by pulling the fixed block with the handle and moving the fixed block's position, as the rolling wheel is connected to the inside of the display rack. This improves the operator's adjustment convenience.

[0016] This invention, through the setting of an elastic structure and a positioning structure, allows the fixing block and pressing plate to automatically move closer to the display rack under the action of the first spring after the operator moves them to the appropriate position. This causes the first rubber pad to automatically adhere to the display panel on the side of the display rack, thereby completing the limiting and fixing of the fixing block and pressing plate. At this time, the anti-slip pad inside the mounting cover is tightly attached to the outer wall of the burr sleeve, further limiting and fixing the fixing block and pressing plate. This further ensures the fixing effect of the device on the engineering cost drawings, facilitating the subsequent display of the engineering cost drawings. Attached Figure Description

[0026] The present invention will be further described below with reference to the embodiments.

[0027] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0028] Please see Figure 1-8This utility model provides an engineering cost drawing display stand, including a display structure 1, which includes a display rack 101 and a mounting base 102 installed at the bottom of the display rack 101. The two sides of the display rack 101 are respectively configured as a display panel 103 and a writing board 104. The sides of the display panel 103 are provided with several sets of sliding grooves 2. Limiting structures 3 are provided inside the sliding grooves 2. The limiting structures 3 are provided with a moving structure 4, an elastic structure 5, and a fixing structure 6. The fixing structure 6 includes a fixing block 601, and the sides of the fixing block 601 are connected by connecting blocks. A pressing plate 603 is fixedly connected to 602. A connecting structure 9 is provided on all fixed blocks 601 except the top one. The connecting structure 9 includes a rotating disk 901 rotatably connected to all fixed blocks 601 except the top one. A vertical plate 903 is fixedly connected to the side of the rotating disk 901 via a telescopic rod 902. A pin 904 is fixedly connected to the side of the vertical plate 903. The connecting structure 9 also includes a fixing groove 908 provided on all fixed blocks 601 except the bottom one. The pin 904 can be selectively inserted into the nearest fixing groove 908.

[0029] Specifically, such as Figure 1 , 3 As shown in Figure 4, the limiting structure 3 includes a connecting plate 302 disposed inside the slide groove 2. The same limiting block 301 is fixedly connected to two adjacent connecting plates 302. The limiting block 301 is slidably connected inside the display rack 101. The fixing block 601 is fixedly connected to the two adjacent connecting plates 302. The moving structure 4 includes a rotating shaft 401 rotatably connected to the interior of the two adjacent connecting plates 302. Two rolling wheels 402 are fixedly connected to the outer wall of the rotating shaft 401. The rolling wheels 402 are rotatably connected to the inner wall of the display rack 101. The cross-sectional shape of the display rack 101 is set as U-shaped with the opening facing downward. By setting the moving structure 4, when the operator pulls the fixing block 601 through the handle 7 and moves the position of the fixing block 601, the rolling wheels 402 are rotatably connected to the interior of the display rack 101, which facilitates the operator to quickly adjust the position of the fixing block 601 and the connecting block 602, thereby improving the operator's adjustment convenience.

[0030] Specifically, such as Figure 5 and 8As shown, the elastic structure 5 includes a connecting rod 502 fixedly connected inside the connecting plate 302. A force-bearing block 501 is fixedly connected to the end of the connecting rod 502 away from the connecting plate 302. Both the force-bearing block 501 and the connecting rod 502 slide inside the fixed block 601. A first spring 503 is fixedly connected between the force-bearing block 501 and the fixed block 601. The first spring 503 is wound around the outer wall of the connecting rod 502. Two first rubber pads 604 are fixedly connected to the side of the fixed block 601 near the display rack 101. The first rubber pads 604 selectively adhere to the display plate 103 on the side of the display rack 101. A second rubber pad 605 is fixedly connected to the side of the pressing plate 603 near the display rack 101. Positioning structures 8 are provided on both the rotating shaft 401 and the fixed block 601. The positioning structure 8 includes a positioning rod 801 fixedly connected to the side of the fixed block 601. A force-bearing block 501 is fixedly connected to the end of the positioning rod 801 away from the fixed block 601. The mounting cover 802 has an anti-slip pad 803 inside. The positioning structure 8 also includes a burr sleeve 804 fixedly connected to the outer wall of the rotating shaft 401. The anti-slip pad 803 selectively adheres to the outer wall of the burr sleeve 804. By setting the elastic structure 5 and the positioning structure 8, when the operator moves the fixing block 601 and the pressing plate 603 to a suitable position, under the force of the first spring 503, the fixing block 601 automatically moves closer to the display rack 101, thereby causing the first rubber pad 604 to automatically adhere to the display plate 103 on the side of the display rack 101, thus completing the limiting and fixing of the fixing block 601 and the pressing plate 603. At this time, the anti-slip pad 803 inside the mounting cover 802 is tightly attached to the outer wall of the burr sleeve 804, thereby further limiting and fixing the fixing block 601 and the pressing plate 603, further ensuring the fixing effect of the device on the engineering cost drawings, and facilitating the subsequent display of the engineering cost drawings.

[0031] Specifically, such as Figure 1 As shown, a handle 7 is fixedly connected to the side of the fixed block 601 away from the display rack 101. The handle 7 is shaped like a U. By setting the handle 7, it is easy for the operator to quickly pull the fixed block 601, thereby facilitating the operator to quickly fix or unfix the engineering cost drawings and improving the ease of use for the operator.

[0032] Specifically, such as Figure 5 and 7As shown, a first protective sleeve 906 is fixedly connected to the outer wall of the rotating disk 901, and a second protective sleeve 907 is sleeved on the outer wall of the first protective sleeve 906. The second protective sleeve 907 is fixedly connected to the upright plate 903. A second spring 905 is fixedly connected between the rotating disk 901 and the upright plate 903. The second spring 905 is sleeved on the outer wall of the telescopic rod 902 and is located inside the first protective sleeve 906 and the second protective sleeve 907. By setting the second spring 905, when the operator releases the force applied to the upright plate 903, the upright plate 903 can automatically move closer to the fixed block 601 under the action of the second spring 905, thereby facilitating the insertion of the pin 904 into the fixed groove 908 and improving the convenience of use for the operator.

[0033] The working principle and usage process of this utility model are as follows: When the operator uses this device to display and process engineering cost drawings, the operator can pull the corresponding upright plate 903 according to the size of the engineering cost drawings. After the upright plate 903 is released from the insertion state with the nearby fixing groove 908, with the cooperation of the rotating disk 901, the operator rotates the upright plate 903, so that the pin 904 moves away from the fixing groove 908. At the same time, with the cooperation of other upright plates 903, pins 904 and fixing grooves 908, the operator can flexibly pull the fixing block 601 assembly with the same width as the engineering cost drawings through a single handle 7, thereby quickly limiting and fixing the engineering cost drawings. The remaining fixing blocks 601 can flexibly fix other engineering cost drawings of different sizes.

[0034] When the operator pulls the fixing block 601 with the handle 7 and moves the position of the fixing block 601, the rolling wheel 402 is rolled and connected to the inside of the display rack 101, which makes it easy for the operator to quickly adjust the position of the fixing block 601 and the connecting block 602.

[0035] When the operator moves the fixing block 601 and the pressing plate 603 to the appropriate position, under the force of the first spring 503, the fixing block 601 automatically moves closer to the display rack 101, thereby causing the first rubber pad 604 to automatically adhere to the display panel 103 on the side of the display rack 101, thus completing the limiting and fixing of the fixing block 601 and the pressing plate 603. At this time, the anti-slip pad 803 inside the mounting cover 802 is tightly attached to the outer wall of the burr sleeve 804, thereby further limiting and fixing the fixing block 601 and the pressing plate 603. The operator can also write on the writing board 104.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
