Description

Technical Field

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

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Tendering is a term in the bidding industry, which refers to the act of the tenderer (buyer) issuing a tender notice or tender form in advance, proposing the variety, quantity, technical requirements and related transaction conditions at a specified time and place, and inviting bidders (sellers) to participate in the bidding. In the management of construction projects, tendering devices are often used for bidding. There are fewer protective structures, poor protective performance, and the device cannot be supplemented with lighting according to the intensity of ambient light. It is not practical and very inconvenient. It is not convenient for staff to disassemble, assemble and replace the tender display board easily and quickly. The work efficiency is not ideal and it is very inconvenient. For this reason, we propose a tendering device for construction project management to solve the existing problems. Utility Model Content

The entire device can be centrally controlled by the control board, and the connecting seat can firmly fix the control board to the storage box to increase the connection stability.

[0008] Preferably, a U-shaped pull rod is fixedly installed on the top of the fastening plate between the clamping bolts, and the outer surface of the U-shaped pull rod is provided with anti-skid patterns. The U-shaped pull rod can be used to move the fastening frame to disassemble and replace the bidding display board, and the anti-skid patterns can increase the contact friction between the U-shaped pull rod and the palm of the user, thereby increasing stability.

[0009] Preferably, a transparent observation plate is fixedly installed on the surface of the storage box between the light detectors, and a magnetic suction piece is fixedly installed on the top of the push plate. The storage box will cooperate with the transparent observation plate to protect the bidding display board without affecting the viewing of personnel, thereby increasing the protection performance of the device, and the magnetic suction piece will tightly adsorb the fastening frame to the push plate, thereby increasing stability and facilitating practicality for personnel.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. During operation, the bidding information of the construction project can be displayed through the bidding display board. The storage box will cooperate with the transparent observation board to protect the bidding display board without affecting the viewing of personnel, thereby increasing the protection performance of the device. During operation, the LED lighting structure can be used to illuminate the inside of the device, so that personnel can view the bidding display board more clearly. The light detector will detect the ambient light intensity of the device, and adjust the LED lighting structure accordingly according to the changes in the intensity of the external light, thereby increasing the energy-saving performance of the device and facilitating the use of personnel.

[0012] 2. The lifting adjustment rod will drive the push plate to move up and down, and it can be automatically pushed out of the device through the push plate, and then the personnel can quickly take out the fastening frame, and then the user can loosen the card bolt and take out the bidding display board from the card cavity to facilitate the replacement work. After the new bidding display board is placed in the card cavity, its position can be limited by the card bolt, and then the fastening frame can be introduced from the top of the device into the device for installation. When the fastening frame is introduced into the device, its position can be limited by sliding on the card displacement piece and the displacement track, which is convenient for personnel to easily disassemble and replace the device. The fastening plate will increase the sealing and dustproof performance of the device after the fastening frame is installed, and the magnetic suction piece will tightly adsorb the fastening frame to the push plate to increase stability.
