Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bidding devices for construction project management, and in particular to a bidding device for construction project 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, attracting contractors to compete for the project through legal procedures and methods, and selecting the most qualified contractor to complete the construction task. During the construction project, it is necessary to tender for the supporting facilities, consumables, and other related materials involved in the construction project. After the construction unit issues the tender notice, each contractor will submit their bids to the construction unit, and then the construction unit will select contractors to supply materials and carry out construction work based on the bids.
[0003] The inventor discovered while reviewing construction project tender documents that, because the tender process requires multiple people to discuss and evaluate the projects, the fact that the tender documents are passed around among many people makes it impossible to gather together for discussion and evaluation, thus causing problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bidding device for construction project management.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a construction project management bidding device, including a support, a display panel is provided on the side of the support, a clamping device is provided on the surface of the display panel, the clamping device includes a threaded rod rotatably connected to the surface of the display panel, a round rod is fixedly connected to the side of the display panel, and a pressing plate is threadedly connected to the surface of the threaded rod.
[0006] The effect achieved by the above components is that, under the action of the threaded rod, the extrusion plate can fix the tender documents on the surface of the display panel, thereby facilitating discussion and evaluation. When it is necessary to manage the tender documents, the tender documents can be fixed on the surface of the display panel according to the date for probing and evaluation.
[0007] Preferably, a rectangular strip, which is a rubber strip, is fixedly connected to the side of the extrusion plate.
[0008] The effect achieved by the above components is that, under the action of the rectangular strip, the tender document will not slip off between the extrusion plate and the display plate, thus avoiding the slippage phenomenon.
[0009] Preferably, a slider is provided on the side of the display panel, a damper is fixedly connected to the side of the slider, and a rectangular plate is fixedly connected to the other end of the damper.
[0010] The effect achieved by the above components is that, under the action of the damper, tender documents of different thicknesses can be fixed on the surface of the display panel, thereby making the tender documents flat and avoiding folding.
[0011] Preferably, a rectangular groove is formed on the surface of the display panel, a fixing rod is fixedly connected to the inner wall of the rectangular groove, and a slider is slidably connected to the surface of the fixing rod.
[0012] The effect achieved by the above components is that, under the action of the rectangular groove and the fixing rod, the rectangular plate can be moved to a suitable position.
[0013] Preferably, an L-shaped plate is fixedly connected to the side of the slider, a circular groove is formed on the surface of the display panel, and a locking rod is inserted into the surface of the L-shaped plate, with the locking rod inserted into the interior of the circular groove.
[0014] The aforementioned components achieve the following effects: Under the action of the locking rod, the slider can be fixed after moving to a suitable position. When it is necessary to discuss the tender document, the threaded rod is turned by hand to move the extrusion plate away from the display plate. The tender document is placed between the extrusion plate and the display plate, and the threaded rod is turned again to make the extrusion plate press smoothly against the surface of the tender document. Under the action of the rectangular bar, the tender document will not slip off between the extrusion plate and the display plate, thus avoiding slippage. Pulling the rectangular plate outward restricts the other end of the tender document between the rectangular plate and the display plate. Pushing the rectangular plate causes the slider to move inside the rectangular groove. When it moves to a suitable position, the locking rod is inserted into the circular groove to fix the position of the slider. Under the action of the damper, the rectangular plate is pressed against the surface of the tender document, preventing the tender document from folding, thus achieving the clamping function.
[0015] Preferably, a supplementary lighting device is provided on the top of the display panel. The supplementary lighting device includes a rectangular frame fixedly connected to the top of the display panel, a power supply fixedly connected to the side of the rectangular frame, a connecting column fixedly connected to the inside of the rectangular frame, a light strip slidably connected to the inside of the rectangular frame, a connecting groove opened on the side of the light strip, and LED beads fixedly connected to the surface of the light strip.
[0016] The effect achieved by the above components is that, under the action of the power supply, the LED beads emit light after the light strip is inserted into the rectangular frame, thereby achieving the function of supplementary lighting.
[0017] Preferably, a locking rod is inserted into the top of the rectangular frame, and one end of the locking rod is inserted into the interior of the light strip.
[0018] The effect achieved by the above components is that, under the action of the locking rod, the light strip is fixed inside the rectangular frame, preventing the light strip from slipping out of the rectangular frame.
[0019] Preferably, a spring is sleeved on the surface of the locking rod, and the two ends of the spring are fixedly connected to one end of the locking rod at the top of the rectangular frame.
[0020] The aforementioned components achieve the following effect: Under the action of the spring, the locking rod will not slip out of the inside of the light strip, thus achieving the function of fixing the locking rod. When discussing the tender documents, the light strip is inserted into the inside of the rectangular frame, so that the connecting groove at one end of the light strip is inserted together with the connecting post, so that the power supply provides power to the light strip, thereby making the LED light up. After the LED light up, the locking rod is inserted into the inside of the light strip, so that the light strip is fixed inside the rectangular frame. Under the action of the spring, the locking rod will not slip out of the inside of the light strip, thus achieving the function of fixing the locking rod, thereby achieving the function of supplementary lighting.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a clamping device, when it is necessary to discuss the tender document, the threaded rod is turned by hand to move the pressing plate away from the display plate. The tender document is placed between the pressing plate and the display plate, and the threaded rod is turned again to make the pressing plate press steadily against the surface of the tender document. Under the action of the rectangular bar, the tender document will not slip off between the pressing plate and the display plate, thus avoiding slippage. Pulling the rectangular plate outward restricts the other end of the tender document between the rectangular plate and the display plate. Pushing the rectangular plate causes the slider to move inside the rectangular groove. When it moves to the appropriate position, the locking rod is inserted into the circular groove to fix the position of the slider. Under the action of the damper, the rectangular plate is pressed against the surface of the tender document, preventing the tender document from folding, thus achieving the clamping function. This solves the problem that multiple people need to discuss and evaluate the tender document together during the bidding process, and because the tender document is passed around among multiple people, it is impossible to gather together for discussion and evaluation.
