The side surface of the extending section of the sliding block 22 is provided with a plugging blind hole for connecting the horizontal limiting column 242.
The thickness side of the upright 1 is provided with a blind hole for a connecting bolt 244.
Before the pole setting was not installed, the spring of elastic clamping component was in unstretched state, and the interval between upper and lower splint is less than the installation interval, and the yoke plate of spacing passes through the bolt tightening in the thickness side outer wall of pole setting, and the spacing post of level of corresponding height inserts in the spliced eye of slider side.
When the design of the limiting frame and the size selection and fixation of the spring are carried out, attention should be paid to the fact that the horizontal limiting column is prevented from interfering with the spring.
The top of the thickness side of the vertical rod 1 is connected with an elastic positioning component 3, and the cross rod 4 is connected through the elastic positioning component, so that the outer sides of the vertical rod at the lowest position and the vertical rod at the highest position are not connected with the elastic positioning component, and the two sides of the vertical rod at the middle position are connected with the elastic positioning components, as shown in fig. 1 and 2.
As can be seen from fig. 1, 2 and 5, the elastic positioning assembly 3 includes a cylindrical barrel 31, an L-shaped plate 32, a sliding rod 33, a spring TH, a positioning plate 34 and an insertion rod 35.
One end face of the cylindrical barrel 31 is an inclined face, and the other end face is a plane.
The end face of one side arm of the L-shaped plate 31 is fixed at the end port of the near plane of the side wall of the cylinder 31, and the other side arm extends out of the end port.
The sliding rod 33 is a cylindrical rod, and the outer end of the sliding rod is provided with a circular pulling plate.

The positioning plate 34 is a rectangular plate, and the thickness side thereof is fixed along the diametric plane of the inner end of the slide bar 33.
The outer end face of the side arm extending from the L-shaped plate 32 is connected with an inserting rod 35 which can be inserted into a radial hole on the sliding rod.
When the elastic positioning component is assembled with the vertical rod, the inclined end of the cylindrical cylinder is fixed with the top of the thickness side of the vertical rod, so that the elastic component is in an inclined state.
The initial state of the elastic positioning component is as follows: the inserted link connected with the L-shaped plate is inserted into the radial hole on the sliding rod, so that the positioning plate is positioned outside the side wall of the cylindrical barrel, and the spring on the sliding rod is in a compressed state.
The upright rod is assembled with the elastic clamping component and the elastic positioning component to form an integral piece and then is installed at the position of a stair, and the concrete process is as follows:
rotating the bolt of the limiting frame to enable the connecting plate to move outwards along the bolt, and driving the horizontal limiting column to move outwards through the vertical rectangular plate to loosen the sliding block;
placing the upper clamping plate on the upper surface of the stair tread, and pulling the lower clamping plate downwards until the upper surface of the lower clamping plate is attached to the bottom surface of the stair, so that the upper clamping plate and the lower clamping plate clamp the stair under the action of the springs;
and reversely rotating the bolt to enable the horizontal limiting column with the corresponding height to be inserted into the inserting hole on the side surface of the sliding block, so that the sliding block is positioned. If the positions of the limiting column and the inserting hole cannot be matched, a gasket can be properly added on the lower clamping plate for auxiliary installation.
After the integral part formed by assembling each upright rod with the elastic clamping component and the elastic positioning component is fixed at the designated position of the stair, the cross rod is installed.
The two ends of the cross bar 4 are respectively provided with a radial groove with the width dimension slightly larger than the thickness of the positioning plate 34.
When the cross rod is assembled, two ends of the cross rod are respectively inserted into the cylindrical barrel of the elastic positioning assembly, the inserted rods are pulled out from the radial holes on the sliding rods, the sliding rods extend forwards under the action of restoring force of the springs, and the positioning plates are inserted into the radial grooves on the cross rod to position the cross rod.
It can be seen through above-mentioned structure and installation operation that this embodiment presss from both sides the stair location installation through the elasticity clamping components of pole setting bottom, and the horizontal pole between the pole setting passes through the installation of elasticity locating components. The whole installation process even does not need to use external tools, and the operation is very simple. The stability after the installation is guaranteed, because be provided with the spring between the upper and lower splint of elastic clamping component and take-up both, the slider and the lower splint of spring lower extreme are even as an organic whole moreover, and slider accessible spacing frame level is spacing to can avoid the lateral shifting of upper and lower splint.
When the cross rod of the protective guard is disassembled, only the inserted rod of the elastic positioning component needs to be pulled out, when the vertical rod is disassembled, only the bolt of the limiting frame needs to be rotated, the horizontal limiting column is made to withdraw from the inserted hole in the side face of the sliding block, then the vertical rod is pulled out of the stair, and the upper clamping plate and the lower clamping plate are made to be separated from the stair.
The disassembled protective guard can be reused, and due to the arrangement of the elastic clamping components, the protective guard can be suitable for different stair installations.
