Description

Technical Field

[0001] The invention relates to the field of construction tools, in particular to a disc-type door frame for construction. Background Art

[0002] The disc-type gantry, also known as the disc-type scaffolding, is a kind of scaffolding system that uses discs and latches to connect the vertical poles, horizontal poles and diagonal poles into a whole, forming a stable and reliable scaffolding system. This product was introduced from Europe in the 1980s and is an upgraded product after the cup-type scaffolding. It is also called the chrysanthemum disc scaffolding system, the plug-in disc scaffolding system, and the wheel disc scaffolding system.

[0003] During the use of disc-type door frames currently on the market, when the connecting disc needs to be connected to multiple cross bars, they are generally installed separately. This requires the staff to perform multiple installations, resulting in low actual installation efficiency. Therefore, how to achieve more convenient installation at the cross bars of the scaffolding is a problem we need to consider. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a disc-type door frame for construction is proposed. During actual use of the door frame, when multiple transverse rods need to be installed, it is only necessary to first place the multiple transverse rods in the corresponding arc-shaped placement grooves, and then use a screwdriver to rotate the rotating block to rotate it, so that the limiting of multiple transverse rods can be achieved synchronously.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Preferably, the driving mechanism includes an annular cavity opened on the inner side of the connecting disc, an annular groove is opened on the outer side wall of the annular cavity, an annular opening is opened on the inner bottom of the annular groove, a rotating tube is arranged in the annular cavity, a rotating disc is fixedly connected to the outer side of the rotating tube, four notched grooves are opened on the rotating disc, each of the rectangular sliding blocks is fixedly connected to a round-headed push rod on the side away from the limiting rod, the other end of each of the round-headed push rods passes through the corresponding rectangular sliding cavity and extends into the annular cavity, and multiple round-headed push rods cooperate with the rotating disc.

[0011] Preferably, a limit plate is fixedly connected to the outer side of the rotating tube, the limit plate is located in the annular groove and is slidably connected to the inner wall of the annular groove, the lower end of the rotating tube passes through the annular opening and is installed with a first gear.

[0012] Preferably, the lower end of the connecting disc is fixedly connected to a vertical plate, the lower end of the vertical plate is fixedly connected to a horizontal plate, a rotating shaft is provided through the horizontal plate, the rotating shaft is rotatably connected to the horizontal plate, the upper end of the rotating shaft is fixedly connected to a second gear, the second gear is meshed with the first gear, the lower end of the rotating shaft is fixedly connected to a rotating block, and a cross groove is provided at the lower end of the rotating block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The user only needs to twist the shaft to drive the rotating disk to rotate through the precise transmission of the gears, and the limit rod is linked to insert or withdraw from the limit groove, so as to quickly fix or release the transverse rod. This process greatly simplifies the cumbersome bolt tightening or disassembly steps in the traditional connection method, and significantly improves the construction efficiency.

[0016] 2. In the limited state, the plug rod tightly locks the position of the shaft through the elastic action of the first spring, ensuring that the shaft will not rotate accidentally due to external force, thereby ensuring the stability of the horizontal rod connection, effectively preventing safety hazards caused by loose connections, and ensuring safety and stability during the construction process.
