[0001] The utility model relates to the technical field of construction engineering, in particular to a publicity device for construction engineering bidding. Background Art

[0002] In the bidding process of construction projects, publicity is crucial. It can not only attract more potential bidders, but also improve the competitiveness and transparency of bidding. Clear publicity goals: aiming to attract potential bidders with corresponding qualifications and capabilities, and ensure the competitiveness and fairness of bidding. Publicity content: including the basic situation of the project, bidding requirements and processes, evaluation criteria and methods, etc. Traditional media: publish bidding information through traditional media such as newspapers and magazines to cover a wide range of target audiences. Network platform: use official websites, industry websites or electronic bidding platforms to publish bidding information, so that potential bidders can quickly obtain relevant information. Targeted invitations: send targeted invitations to potential bidders with specific qualifications and experience to improve the pertinence and effectiveness of bidding, which includes propaganda boards used in publicity.

[0003] When using propaganda boards, it is necessary to ensure the efficiency of the use of propaganda boards and facilitate their movement and storage. However, we consider that traditional propaganda boards are directly placed on the ground for use, lack of storage, and thus affect subsequent use, which is extremely inconvenient. Therefore, a propaganda device for construction project bidding is urgently needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a publicity device for construction project bidding, which solves the problem in the prior art that publicity boards are directly placed on the ground for use and lack storage, thus affecting subsequent use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A publicity device for construction project bidding comprises a frame, a carrying frame is slidably connected to the inner side of the frame, a publicity board is provided on the inner side of the carrying frame, sliders are fixedly connected to both sides of the carrying frame, and the two sliders are slidably connected to the inner wall of the frame through sliding grooves, a side plate is fixedly connected to one side of the outer wall of the frame, a connecting block is fixedly connected to one side of one of the two sliders, an insertion rod is provided on one side of the side plate, and slots for matching with the insertion rod are provided on one side of the side plate and one side of the connecting block.

[0007] Preferably, both sides of the carrying frame are provided with limiting rods, and one side of the publicity board and both sides of the carrying frame are provided with limiting grooves for use with the limiting rods.

[0008] Preferably, the top of the frame is rotatably connected to a top cover via a hinge.

[0009] Preferably, a plurality of slots are provided on the side panel.

[0010] Preferably, the two sliders are clearance-fitted with the two slide grooves respectively.

[0011] Preferably, the two limiting rods are symmetrically distributed along the center of the frame.

[0012] The utility model has at least the following beneficial effects:

[0013] When the utility model is used as a publicity device for construction engineering bidding, the frame is first opened, and the supporting frame can be moved up manually at the same time. When the publicity board is moved to the outside of the frame, the insertion rod is plugged into the slots on the side panels and the connecting block to limit the supporting frame and the publicity board. After the publicity board is used, it can be stored according to the same principle, which is convenient for subsequent use. Compared with the problem in the prior art that the publicity boards are directly placed on the ground for use, lack of storage, and thus affecting the subsequent use, the method proposed in the utility model is to plug and limit the insertion rod into the slots on the side panels and the connecting block when the publicity board is moved to the outside of the frame, thereby realizing the storage and use of the publicity board and improving the service life of the publicity board.
