Description

Technical Field

[0001] This utility model relates to the field of electronic bidding terminal technology, and in particular to a multi-screen interactive electronic bidding terminal for traffic engineering. Background Technology

[0002] Multi-screen electronic bidding terminals, with their features such as multi-screen display, remote bidding and Q&A, document management and annotation, intelligent check-in and meeting control, and audio and video recording and storage, provide a convenient and efficient solution for modern electronic bidding and evaluation processes.

[0003] In the prior art, Chinese Patent No. CN215636339U discloses a multi-screen display mobile communication terminal device, including multiple liquid crystal displays arranged side by side. Each liquid crystal display has a mounting mechanism on its back. The mounting mechanism includes a mounting plate, on which are an adjustment component and a snap-fit ​​component. The adjustment component includes a sliding seat slidably mounted on the mounting plate near one end of the liquid crystal display, a pair of hydraulic push rods vertically fixed to the sliding seat near one end of the liquid crystal display, and a connecting plate rotatably mounted on the telescopic ends of the two hydraulic push rods. The connecting plate is connected to the liquid crystal display. Side plates are horizontally fixed on the mounting plate below and below the sliding seat, and several limiting pin holes are evenly spaced and arranged side by side on the side plates. This patent facilitates the splicing and installation of multiple liquid crystal displays and has good adjustment performance.

[0004] In the above technical solutions, the installation method of the installation mechanism is relatively simple, and the fixed installation method limits the mobility and flexibility of the terminal. Once the terminal is fixed in a certain position, it is difficult to adjust its position or rearrange it, which may cause many inconveniences in practical applications. For example, during the bidding process, if the on-site environment is not sufficient to support suspended installation, it will affect the progress of the bidding process and reduce the efficiency of the bidding.

[0005] Based on this, a multi-screen interactive electronic bidding terminal for traffic engineering is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-screen interactive electronic bidding terminal for traffic engineering to solve the problems mentioned in the background art.

Two fixed seats are fixedly connected to one side of the connecting plate. The two fixed seats are rotatably connected to the same rotating shaft on their opposite surfaces. Two rotating blocks are fixedly connected to the surface of the rotating shaft, and a ratchet is fixedly connected to the surface of the rotating shaft. A coil spring shaft is fixedly installed on one side of one of the fixed seats, and a pawl is fixedly connected to the surface of the coil spring shaft. The pawl engages with the ratchet.

[0010] In some embodiments, the opposite surfaces of the two rotating blocks are fixedly connected to the same sliding rod, the surface of the sliding rod is slidably connected to a second slider, and the surface of the sliding rod is fixedly connected to a second fixing block.

[0011] In some embodiments, a rotating rod is rotatably connected to the inner wall of the slider one, and a rotating rod is rotatably connected to the inner wall of the fixed block one. The end of the rotating rod one away from the slider one is rotatably connected to the inner wall of the fixed block two, and the end of the rotating rod two away from the fixed block one is rotatably connected to the inner wall of the slider two.

[0012] In some embodiments, the first rotating rod and the second rotating rod are rotatably connected, and the mounting plate is provided with a plurality of fastening bolts, which are symmetrically and evenly distributed.

The electric telescopic rod on the fixing mechanism, together with the rotating seat, can make fine adjustments to the angle of the display and improve the display effect.

[0015] Secondly, this utility model disengages the ratchet from the ratchet by rotating the pawl, then rotates the mounting plate. The rotating block drives the rotating shaft to rotate 90 degrees on the fixed seat, achieving a vertical arrangement between the mounting plate and the connecting plate. At this point, the mounting plate is fixed to the ground with fastening bolts, thus completing the placement and installation. By starting the motor, the motor drives the screw to rotate, which allows the first slider to slide. The sliding of the first slider allows the first rotating rod to rotate, which in turn allows the second rotating rod to rotate, thereby allowing the second slider to slide. This adjusts the distance between the mounting plate and the connecting plate, thereby achieving height adjustment of the display screen to accommodate height adjustments during placement and installation, improving the display effect.
