Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to a bidding device for construction engineering management. Background Technology

[0002] Construction project bidding refers to the legal act by which a construction unit issues a public notice for a proposed project, attracts contractors to compete for the project through legal procedures and methods, and selects the most qualified contractor to complete the construction task. Bidding devices are required in construction project bidding, mainly for displaying the bidding results.

[0003] According to the patent document with publication number CN221763093U, the patent document describes a method where two display groups are pulled to move away from the display body to a suitable position. The display body is then activated to display electronic materials, while the two display groups display paper materials. By rotating the half-gear column, the disc gear rotates within the cylindrical sleeve base, which in turn rotates the connecting group, thereby causing the display mechanism and the display body to rotate and adjust the display angle.

[0004] The patent document states that when people view the exhibited materials, the fixed display height leads to unsuitable angles due to the varying heights of the viewers, which can easily cause visual fatigue or information omissions. Furthermore, the large overall size of the bidding device results in it taking up a lot of space during transportation, making it inconvenient to transport. Utility Model Content

[0005] The purpose of this utility model is to provide a construction project management bidding device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A construction project management bidding device includes a base plate and a first fixing plate. The first fixing plate is fixed to one side of the top of the base plate, and a second fixing plate is fixed to the other side of the top of the base plate. First sliding blocks are slidably connected to the sides of the first and second fixing plates that are close to each other. A connecting column is fixed between the two first sliding blocks. A rotating shaft is rotatably connected inside the first fixing plate, and a second sliding block is slidably connected to the outside of the rotating shaft. The second sliding block is fixedly connected to the first sliding block located on one side of the connecting column. A support frame is rotatably connected to the outside of the connecting column. Several first limiting strips are fixed to both ends of the support frame. Four second limiting strips that cooperate with the several first limiting strips are fixed to both ends of the connecting column.

[0008] Preferably, a display screen is fixed to the top of the support frame, a display rack is fixed to the front of the display screen, two display panels are slidably connected inside the display rack, and a limiting post is fixed to the top of the display panel to prevent the display panel from slipping.

[0009] Preferably, the display rack has first square grooves on both sides for the display board to slide out, and two second square grooves on the top of the display rack for cooperating with two limiting posts.

[0010] Preferably, all four corners of the bottom of the base plate are fixed with casters.

[0011] Preferably, the first fixing plate and the second fixing plate are provided with a groove on the side that is close to each other, which cooperates with the first sliding block.

[0012] Preferably, a motor is fixedly installed at the input end of the rotating shaft, and a spiral groove that cooperates with the second sliding block is opened on the outer side of the rotating shaft.

[0013] Preferably, the tips of the first and second limiting bars that are close to each other have a certain deformation capability.

[0014] The advantages compared to existing technologies are as follows: The second sliding block is moved vertically by the pivot, thereby adjusting the height of the support frame, display screen, display rack and two display panels. The tilt angle of the display screen and two display panels can be adjusted by pulling the support frame to rotate around the connecting column, which can meet the needs of viewers of different heights, further improving flexibility and user experience.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-10 As shown, a construction project management bidding device includes a base plate 1 and a first fixing plate 2.

[0031] In this embodiment: a first fixing plate 2 is fixed to one side of the top of the base plate 1, and a second fixing plate 3 is fixed to the other side of the top of the base plate 1. First sliding blocks 4 are slidably connected to the sides of the first fixing plate 2 and the second fixing plate 3 that are close to each other. A connecting post 5 is fixed between the two first sliding blocks 4. A rotating shaft 7 is rotatably connected inside the first fixing plate 2, and a second sliding block 6 is slidably connected to the outside of the rotating shaft 7. The second sliding block 6 is fixedly connected to the first sliding block 4 located on one side of the connecting post 5. A support frame 9 is rotatably connected to the outside of the connecting post 5, and both ends of the support frame 9 are fixed with... Several first limiting strips 10 are provided, and four second limiting strips 11 that cooperate with the several first limiting strips 10 are fixed at both ends of the connecting column 5. The second sliding block 6 is driven to move vertically through the rotating shaft 7, which in turn drives the two first sliding blocks 4 and the connecting column 5 to move vertically, thereby adjusting the height of the support frame 9, the display screen 12, the display rack 13 and the two display panels 14. During transportation, the second sliding block 6 reaches the lowest end of the first fixed plate 2. By pulling the support frame 9 to rotate around the connecting column 5, the tilt angle of the display screen 12 and the two display panels 14 can be adjusted.

[0032] In this embodiment: a display screen 12 is fixed to the top of the support frame 9, and a display rack 13 is fixed to the front of the display screen 12. Two display panels 14 are slidably connected inside the display rack 13. A limiting post 15 is fixed to the top of the display panel 14 to prevent the display panel 14 from slipping. The two sliding display panels 14 are stored in the display rack 13 when not in use to cover and protect the display screen 12.

[0033] In this embodiment: both sides of the display rack 13 are provided with first square grooves for the display panels 14 to slide out, and the top of the display rack 13 is provided with two second square grooves for cooperating with two limiting posts 15. The two first square grooves allow the two display panels 14 to slide out to the sides of the display rack 13 respectively, and the two second square grooves limit the movement range of the two limiting posts 15.

[0034] In this embodiment: omnidirectional wheels 16 are fixed at the four corners of the bottom of the base plate 1, which facilitates the movement of the bidding device.

[0035] In this embodiment, the first fixing plate 2 and the second fixing plate 3 are provided with sliding grooves that cooperate with the first sliding block 4 on their respective sides. The two first sliding blocks 4 and the connecting column 5 are driven to move in the vertical direction by the second sliding block 6, and the two first sliding blocks 4 move in the corresponding sliding grooves.

[0036] In this embodiment: a motor 8 is fixedly installed at the input end of the rotating shaft 7, and a spiral groove that cooperates with the second sliding block 6 is opened on the outer side of the rotating shaft 7. The rotating shaft 7 is driven to rotate by the motor 8, thereby driving the second sliding block 6 to move vertically in the spiral groove.

[0037] In this embodiment: the tips of the first limiting strip 10 and the second limiting strip 11 that are close to each other have a certain deformation capability. After the support frame 9 is driven by force to move several first limiting strips 10 and corresponding second limiting strips 11 relative to each other, the second limiting strip 11 limits the first limiting strip 10 to ensure that the support frame 9 does not rotate when it is not under force.

[0038] Working principle: When using the bidding device, pull the two limiting posts 15 to both sides to pull the two display panels 14 out from the two first square slots to display the bidding documents. When the viewer needs to adjust the height and angle, the motor 8 drives the rotating shaft 7 to rotate, causing the second sliding block 6 to move vertically in the spiral groove, which in turn causes the two first sliding blocks 4 and the connecting post 5 to move vertically. The two first sliding blocks 4 move in their corresponding sliding grooves, thereby adjusting the support frame 9, the display screen 12, the display rack 13, and the two display panels 14. At a height of 4, the support frame 9 is pulled to rotate around the connecting column 5. The support frame 9 is subjected to force, causing several first limiting strips 10 and corresponding second limiting strips 11 to move relative to each other. The second limiting strips 11 limit the first limiting strips 10, thereby adjusting the tilt angle of the display screen 12 and the two display panels 14. When the use or transportation is finished, the two display panels 14 are pushed into the display rack 13. The motor 8 drives the second sliding block 6 to reach the lowest end of the first fixed plate 2, so that the display screen 12 enters between the first fixed plate 2 and the second fixed plate 3.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
