[0028] The utility model discloses an embodiment in detail below in conjunction with the drawings, but the utility model can be implemented by the following multiple different ways defined and covered.

[0029] Please refer to Figures 1-6 The utility model provides a technical scheme: folding type exempts from nail protective fence, including door board 1 and mounting assembly, and mounting assembly includes the connecting rod 2 of installing at the top and bottom of door board 1, the sleeve 3 of setting up at the both ends of connecting rod 2 and adjusting unit, and adjusting unit provides axial support to sleeve 3, makes sleeve 3 abuts on the wall surface on both sides in the hole, to fix door board 1 in the hole;

[0030] When installing door board 1, only need to put door board 1 into the hole, then through adjusting unit to sleeve 3 axial support is added, makes sleeve 3 away from the center of connecting rod 2, thus makes the sleeve 3 spacing of both ends of connecting rod 2 increase, to be extruded on the wall surface on both sides in the hole through the sleeve 3 of both ends of connecting rod 2, realizes the fixation of door board 1 in the hole through the friction between sleeve 3 and wall surface, and when needing to dismount door board 1, only need to eliminate the axial support of adjusting unit to sleeve 3, to make the distance between the sleeve 3 of both ends of connecting rod 2 reduce, make sleeve 3 and the wall surface on both sides in the hole contact, at this time, door board 1 can be directly removed from the hole, through the cooperation of connecting rod 2, sleeve 3 and adjusting unit, realize the installation and dismounting of door board 1 in the hole, make the installation and dismounting of door board 1 more simple, simultaneously when installing and dismounting door board 1, will not cause damage to wall surface or mounting assembly, makes mounting assembly can be repeatedly used, reduces the use cost of protective fence, simultaneously after dismounting door board 1, need not to repair wall surface, saves construction process.

[0031] Specifically, when installing the sleeve 3 at both ends of the connecting rod 2, try to make the sleeve 3 and the connecting rod 2 on the same straight line. In this way, the reaction forces generated by the sleeve 3 at both ends of the connecting rod 2 when they come into contact with the wall are also on the same straight line and in opposite directions, which can increase the overall stability of the door panel 1 after installation.

[0032] like Figure 5 As shown, mounting rings 9 are provided at both the top and bottom of the door panel 1, and connecting rods 2 are inserted into the mounting rings 9. In actual construction, the dimensions of different openings may vary. By providing mounting rings 9 at both the top and bottom of the door panel 1, connecting rods 2 of different lengths can be replaced according to the different sizes of openings. At the same time, different numbers of door panels 1 can be selected according to the size of the openings. When making the door panel 1, the width of the door panel 1 can be reduced as much as possible, so that the door panel 1 is more adaptable to openings of different sizes.

[0033] This device allows for the selection of different numbers of door panels 1 based on the size of the opening. By combining different numbers of door panels 1, the overall protection range can be adjusted to protect openings of different sizes. After adjusting the number of door panels 1, it is also necessary to select connecting rods 2 of different lengths based on the size of the opening. Compared to customizing the overall guardrail, customizing the size of the connecting rods 2 is simpler and more convenient, making the overall guardrail more practical.

[0034] Specifically, in order to allow the connecting rod 2 to be completely removed from the mounting ring 9, the sleeves 3 at both ends of the connecting rod 2 can be separated from the connecting rod, or the inner ring size of the mounting ring 9 is larger than the cross-sectional size of the sleeve 3, so that the connecting rod 2 and the sleeve 3 can leave the mounting ring 9 at the same time. Preferably, the inner hole size of the mounting ring 9 matches the cross-sectional size of the connecting rod 2, so that the connecting rod 2 will not wobble after being inserted into the mounting ring 9, thereby increasing the stability of the door panel 1 after the overall device is installed and making the door panel 1 less prone to wobble.

[0035] Furthermore, such as Figure 2 As shown, a retaining plate 4 is provided at one end of the sleeve 3 away from the center of the connecting rod 2. The retaining plate 4 is used to abut against the outer wall of the opening when the sleeve 3 abuts against the inner and outer walls of the opening. The retaining plate 4 can prevent the door panel 1 from tipping over in one direction.

[0036] After the door panel 1 is installed in the opening using the mounting assembly, if the door panel 1 is subjected to a severe impact or shock, the connection between the mounting assembly and the opening may fail. Therefore, a retaining plate 4 is installed on the sleeve. When installing the door panel 1 in the opening using the mounting assembly, if... Figure 2As shown, the clamping plate 4 can abut against the wall outside the opening. By abutting against the wall outside the opening, the door panel 1 can be prevented from tipping over in one direction. In the actual use of the guardrail, one side of the opening faces the interior of the building (or the work area of ​​the staff), and the other side faces the dangerous area. The impact point of the door panel 1 is from the interior of the building to the dangerous area. Therefore, when installing the door panel 1 by means of the installation components, the clamping plate 4 can be abutted against the wall outside the side of the opening facing the interior of the building to prevent the door panel 1 from tipping over under the impact of external force, thereby improving the protective effect of the overall device.

[0037] like Figure 2 As shown, in some examples, a rubber pad 5 is provided at the end of the sleeve 3 away from the center of the connecting rod 2. The sleeve 3 contacts the wall inside the opening through the rubber pad 5. When the door panel 1 is installed in the opening through the installation assembly, the sleeve 3 in the installation assembly abuts against the wall inside the opening to fix the door panel 1. The rubber pad 5 at the end of the sleeve 3 away from the center of the connecting rod 2 increases the friction between the sleeve 3 and the wall when the sleeve 3 abuts against the wall inside the opening, thereby increasing the stability of the door panel 1 after it is fixed.

[0038] Figure 3 An example of an adjustment unit is shown. In this example, the adjustment unit is a spring 6 located inside the sleeve 3. One end of the spring 6 abuts against the end of the connecting rod 2, and the other end abuts against the side of the sleeve 3 opposite to the connecting rod 2. When installing the door panel 1, the connecting rod 2 and the sleeve 3 are selected according to the size of the opening for installing the door panel 1. In the initial state, the total length of the connecting rod 2 and the sleeve 3 needs to be greater than the width of the opening. When installing the door panel 1, the sleeve 3 is first moved towards the center of the connecting rod 2, so that the spring 6 is compressed. After the connecting rod 2 and the sleeve 3 are placed into the opening, the spring 6 returns to its original position and pushes the sleeve 3 against the walls on both sides of the opening, thereby fixing the door panel 1.

[0039] In this example, the adjustment unit is spring 6. The spring 6 is compressed to generate elastic force to provide axial support to the sleeve 3, so as to achieve the contact between the sleeve 3 and the inner wall of the opening. It is simple and convenient to use.

[0040] Figure 4Another example of the adjusting unit is shown, in this example, the adjusting unit is the internal thread opened in the inner cavity of the sleeve 3 and the external thread opened at both ends of the connecting rod 2, so that the sleeve 3 is threadedly engaged at both ends of the connecting rod 2, and the sleeve 3 is moved along the axial direction of the connecting rod 2 by rotating the sleeve 3, so as to realize the sleeve 3 away from or close to the center of the connecting rod 2, when installing the door panel 1, first rotate the sleeve 3 to move the sleeve 3 to the center of the connecting rod 2, so that the total length of the connecting rod 2 and the sleeve 3 is less than the width of the hole, so that it can be put into the hole, then after the connecting rod 2 and the sleeve are put into the hole, rotate the sleeve 3 to move the sleeve 3 away from the center of the connecting rod 2 along the axial direction of the connecting rod, so that the total length of the connecting rod 2 and the sleeve 3 increases, and finally the sleeve 3 abuts against the wall on both sides of the hole to realize the fixation of the door panel 1.

[0041] In this example, the adjusting unit is the thread opened in the sleeve 3 and the connecting rod 2, the sleeve 3 is moved along the axial direction of the connecting rod 2 by threadedly engaging the sleeve 3 and the connecting rod 2, so as to realize the adjustment of the total length of the connecting rod 2 and the sleeve 3, so as to realize the abutment fixation of the sleeve 3 and the wall on the inside of the hole.

[0042] Specifically, as shown in Figure 4 the rubber pad 5 is rotatably arranged at one end of the sleeve 3 away from the center of the connecting rod 2 with the axis of the sleeve 3 as the rotation axis, and the clamping plate 4 is rotatably arranged at one side of the sleeve 3 away from the center of the connecting rod 2 with the axis of the sleeve 3 as the rotation axis, when the sleeve 3 and the connecting rod 2 are threadedly engaged, if it is necessary to adjust the position of the sleeve 3 on the connecting rod 2, it is necessary to rotate the sleeve 3, and when installing the door panel 1, the sleeve 3 will abut against the wall on the inside of the hole through the rubber pad 5, and there will be a large friction force between the rubber pad 5 and the wall on the inside of the hole, if the rubber pad 5 is fixedly connected with the sleeve 3, then the rubber pad 5 will also rotate when the sleeve 3 is rotated, if the rubber pad 5 contacts the wall at this time, then the rubber pad 5 will slide and rub against the wall when the rubber pad 5 rotates, which will cause the wear of the rubber pad 5, and the clamping plate 4 cannot rotate synchronously with the sleeve 3 because it needs to abut against the wall on the outside of the hole, therefore, the rubber pad 5 and the clamping plate 4 need to be rotatably arranged on the sleeve 3, so that the rubber pad 5 and the clamping plate 4 can remain relatively stationary with the connecting rod 2 when the sleeve 3 is rotated, so as to reduce the wear of the rubber pad 5 and ensure the normal use of the clamping plate 4.

[0043] Further, as shown in Figure 4 the knob 7 is fixedly arranged on the outer surface of the sleeve 3, and the knob 7 is hexagonal, which is convenient for rotating the sleeve 3 by tools such as wrenches.

[0044] As shown in Figure 5As shown in the drawings, in some examples, the door plate 1 is provided with a boss 8 at the bottom, which is used to contact the ground to suspend the sleeve 3, so that after the door plate 1 is put into the hole, the boss 8 can contact the ground to suspend the sleeve 3, so that the sleeve 3 can move along the axial direction of the connecting rod 2.

[0045] As shown in the drawings, Figure 6 As shown in the drawings, in some examples, the door plate 1 is provided with a boss 8 at the bottom, which is used to contact the ground to suspend the sleeve 3, so that after the door plate 1 is put into the hole, the boss 8 can contact the ground to suspend the sleeve 3, so that the sleeve 3 can move along the axial direction of the connecting rod 2.

[0046] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
