[0032] The utility model is described in detail below.

[0033] like Figures 1-4 As shown:

[0034] A portable and adjustable wall opening 100 protection device is used to close and protect the wall opening 100, including a closing plate 1, a horizontal abutment 3 arranged on the closing plate 1 and symmetrically arranged along the Y-axis direction, and a vertical abutment 2 arranged on the closing plate 1; the vertical abutment 2 and the horizontal abutment 3 slide together with the closing plate 1; specifically, the vertical abutment 2 slides together with the closing plate 1 along the Y-axis direction, and the horizontal abutment 3 slides together with the closing plate 1 along the X-axis direction.

[0035] For example, when the wall opening 100 is rectangular, the vertical abutting member 2 is used to abut against the upper and lower side surfaces of the inner side of the wall opening 100, and the horizontal abutting member 3 is used to abut against the left and right side surfaces of the inner side of the wall opening 100;

[0036] When in use, first place the entire device in the wall opening 100, then adjust the horizontal abutment 3 and the vertical abutment 2, and make the end of the horizontal abutment 3 away from the closing plate 1 abut against the inner side of the wall opening 100, and the end of the vertical abutment 2 away from the closing plate 1 abut against the inner side of the wall opening 100; in this way, the entire device will be fixed in the wall opening 100 due to the abutment and cooperation between the horizontal abutment 3 and the vertical abutment 2 and the inner side of the wall opening 100, thereby achieving the sealing and protection of the wall opening 100;

[0037] When dismantling, it is sufficient to control the horizontal abutting member 3 and the vertical abutting member 2 not to abut against the inner side surface of the wall opening 100; installation and dismantling are simple and convenient and will not cause damage to the wall.

[0038] In some possible embodiments, the vertical abutment member 2 includes a gear assembly 22 rotatably mounted on the closing plate 1, and a vertical abutment rod 21 that is in transmission engagement with the gear assembly 22 and disposed along the Y-axis direction; the vertical abutment rod 21 is in sliding engagement with the closing plate 1;

[0039] Specifically, when in use, the gear assembly 22 is controlled to drive the vertical abutment rod 21 to slide on the closing plate 1 along the Y-axis direction, so that the end of the vertical abutment rod 21 away from the closing plate 1 abuts against the inner side of the wall opening 100.

[0040] In some possible embodiments, the gear assembly 22 includes a rotating shaft 221 arranged along the Z-axis direction and rotatably mounted on the closing plate 1, a gear 222 sleeved on the outside of the rotating shaft 221, and a tooth 211 arranged on the vertical abutment rod 21 and meshing with the gear 222;

[0041] The gear assembly 22 further includes a bearing disposed on the closing plate 1 and sleeved on the outside of the rotating shaft 221 , a handle 223 detachably connected to one end of the rotating shaft 221 , and a locking member for locking the closing plate 1 and the gear 222 .

[0042] Preferably, the handle 223 is removed after the entire device abuts against the wall opening 100, thereby preventing construction workers from removing it at will.

[0043] The axis of the rotating shaft 221 is arranged along the Z axis, and the gear 222 is fixedly sleeved on the outer side of the rotating shaft 221. The rotating shaft 221 is rotatably connected to the closing plate 1 through a bearing. The outer ring of the bearing is fixedly connected to the closing plate 1, and the inner ring of the bearing is fixedly connected to the rotating shaft 221. The handle 223 drives the rotating shaft 221 to rotate, thereby realizing the rotation of the gear 222. Since the gear 222 is engaged with the vertical abutting rod 21, the vertical abutting rod 21 is driven to slide along the Y axis in the slide groove 11.

[0044] After the end of the vertical abutting rod 21 abuts against the inner side of the wall opening 100 , the locking member locks the gear 222 and the closing plate 1 , so that the vertical abutting rod 21 remains in abutment with the inner side of the wall opening 100 .

[0045] There are two groups of vertical abutment rods 21. Two groups of slide grooves 11 that slide with the vertical abutment rods 21 are provided on the closing plate 1. The slide grooves 11 are provided along the Y-axis direction and on both sides of the gear 222.

[0046] The ends of the two sets of vertical abutting rods 21 that are away from each other are driven by the gear 222 to abut against the top and bottom of the inner side surface of the hole respectively.

[0047] In some possible embodiments, in order to effectively lock and fix the gear 222 and the closing plate 1 through a locking member, the locking member includes a through hole provided on the gear 222, a plurality of groups of threaded holes provided on the closing plate 1 and used in conjunction with the through hole, and a locking screw having one end passing through the through hole and being threadedly connected to one of the groups of threaded holes.

[0048] After the end of the vertical abutting rod 21 abuts against the inner side of the wall opening 100, the through hole on the gear 222 will be coaxially connected to a group of threaded holes on the closing plate 1. At this time, one end of the locking screw is passed through the through hole and screwed into the threaded hole, so that the locking screw and the closing plate 1 are connected to form a whole, thereby restricting the rotation of the gear 222 and preventing the vertical abutting rod 21 from moving.

[0049] In some possible embodiments, the chute 11 is a dovetail groove or a T-shaped groove, and a slider used in conjunction with the chute 11 is provided on the vertical abutment rod 21; when the chute 11 is a dovetail groove or a T-shaped groove, the small end is open, and the slider is a dovetail block or a T-shaped block;

[0050] The setting of the sliding groove 11 will guide the sliding direction of the vertical abutment rod 21, and the cooperation between the dovetail groove or T-slot and the slider will effectively prevent the closing plate 1 from separating from the vertical abutment rod 21;

[0051] Furthermore, a groove is provided on the side of the vertical abutting rod 21 close to the gear 222, and a tooth is provided at the bottom of the groove; when the vertical abutting rod 21 moves outward from the chute 11 to the maximum position, the side of the groove away from the limiting member 23 cooperates with the gear 222 to limit the vertical abutting rod 21 from sliding further, thereby preventing the vertical abutting rod 21 from sliding out of the chute 11 along the Y-axis direction;

[0052] In some possible implementations, in order to prevent the entire device from falling into the front hole under the action of external force, a limiting member 23 is provided at the end of the vertical abutting rod 21 to abut against the wall hole 100.

[0053] In some possible embodiments, the limiting member 23 is L-shaped, including an abutment plate 231 installed at the end of the vertical abutment rod 21 and abutting the inner side of the hole, and a limiting plate 232 vertically connected to the abutment plate 231 and located outside the hole.

[0054] The abutment plate 231 is used to achieve abutment cooperation with the inner side surface of the wall opening 100 under the drive of the vertical abutment rod 21, and the limiting plate 232 is vertically installed on the abutment plate 231 and will be located on the outside of the wall opening 100; after the abutment plate 231 abuts and cooperates with the inner side surface of the wall opening 100, if an external force is applied, the limiting plate 232 will prevent the entire device from falling into the wall opening 100 under the action of the external force.

[0055] In some possible embodiments, the transverse abutment 3 includes a sleeve 31 mounted on the closing plate 1, a transverse abutment rod 32 inserted into the sleeve 31 and slidingly engaged with the sleeve 31, and a locking bolt 33 for locking the sleeve 31 and the transverse abutment rod 32.

[0056] After the vertical abutment rod 21 is in place, the horizontal abutment rod 32 is moved so that the end of the horizontal abutment rod 32 is in contact with the inner side of the wall opening 100;

[0057] After the end of the transverse abutting rod 32 abuts against the inner side of the wall opening 100, the sleeve 31 is connected and fixed to the transverse abutting rod 32 by the locking bolt 33;

[0058] Specifically, the transverse abutment rod 32 is provided with a plurality of groups of holes along its axial direction, and the sleeve 31 is provided with holes used in conjunction with the holes, thereby cooperating with the locking bolt 33 to achieve the fixation of the transverse abutment rod 32 and the sleeve 31;

[0059] Of course, a limiting member 23 identical to the end of the vertical abutting rod 21 may also be provided at the end of the transverse abutting rod 32 , which will not be described in detail here.

[0060] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
