Description

Technical Field

[0001] The utility model belongs to the technical field of stairs, and specifically relates to a staircase protection fixing device. Background Art

[0002] For stairwells in frame-structured buildings, the walls are often built with aerated concrete blocks. During the actual construction process, the outer walls will be built first, and the inner walls will be delayed due to insufficient space for setting up the operating frame. This will form more edges, some of which are more than 2m high. Therefore, in addition to the internal edges of the two stair sections that need safety protection, edge guardrails must also be installed on the inside of the stairwell, and protective fixings are required when installing the guardrails.

[0003] The existing protective fixing device has a complicated structure when in use, which makes the installation operation complicated, time-consuming and labor-intensive, and leads to high manufacturing costs, which causes inconvenience to people's use. This phenomenon has become a problem that needs to be solved urgently by people in this field. Utility Model Content

By providing the lower end plate, the connecting rod, the upper end plate, the torque nut and the protective sleeve rod, the function of quick assembly is realized, thereby improving the convenience of operation, solving the time and labor caused by cumbersome operation, and the overall structure is simple, which effectively saves manufacturing costs, thereby meeting people's work needs.

[0006] Furthermore, a positioning hole is provided on the inner wall of the lower end plate, and the connecting rod is connected to the lower end plate through the positioning hole, which facilitates the installation of the connecting rod.

[0007] Furthermore, the end of the bottom of the connecting rod extending into the interior of the positioning hole is smaller than the size of the end outside thereof, thereby preventing the connecting rod from passing through the lower end plate.

[0008] Furthermore, a thread is provided on the top of the connecting rod, and the connecting rod is engaged with the torque nut through the thread, so that the torque nut can be easily rotated and then slid.

[0009] Furthermore, the bottom of the torsion nut abuts against the top of the upper end plate, facilitating the fixation of the upper end plate.

[0010] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0011] (1) By providing a lower end plate, a connecting rod member, an upper end plate, a torsion nut, and a protective sleeve rod, the function of rapid assembly is realized, thereby improving the convenience of operation, solving the time-consuming and laborious problem caused by cumbersome operation, and the overall structure is simple, effectively saving the manufacturing cost, and thus meeting the work requirements of people.
