[0002] Interior decoration includes room design, decoration, furniture arrangement and various small decorations, focusing on the decoration construction inside the building. It not only includes the decoration design and construction period, but also the long-term decoration after moving in. Scaffolding is used in interior decoration, such as wall painting and indoor ceiling decoration, so that construction workers can use scaffolding to perform high-altitude operations.

[0003] Most existing scaffolds are fixed after being overlapped, and their stepping area is fixed and cannot be flexibly adjusted according to the indoor area. Although some scaffolds expand the area by overlapping extension plates, the end faces of the extension plates are insufficiently supportive and have low load-bearing performance, making them inconvenient to use. Therefore, the present application proposes a scaffold for interior decoration. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 5 As shown, an embodiment of the present application provides a scaffold for interior decoration, comprising:

[0026] A base plate 1, with first expansion plates 2 movably inserted at both ends thereof, with columns 3 provided on both first expansion plates 2, a first receiving slot being provided through the base plate 1, and both first expansion plates 2 being slidably inserted into the first receiving slot;

[0027] The top plate 4 has a second expansion plate 5 movably inserted at both ends thereof, and a second accommodating groove is provided in the top plate 4. The two second expansion plates 5 are slidably inserted in the second accommodating grooves. The two second expansion plates 5 are penetrated by a through hole, and the two posts 3 slide through the two through holes respectively. A self-locking piece 6 is provided on the second expansion plate 5. When the second expansion plate 5 slides along the post 3, the self-locking piece 6 is used to lock the second expansion plate 5 and the post 3. When the area needs to be expanded, the two first expansion plates 2 are pulled away from each other, thereby driving the two second expansion plates 5 away from each other. Since the second expansion plate 5 is provided with a self-locking piece 6 that acts on the post 3, even after the two second expansion plates 5 move to complete the expansion area, the two posts 3 can effectively support the second expansion plate 5. Preferably, the number of posts 3 on the same first expansion plate 2 is two, so as to further improve the supporting effect of the second expansion plate 5;

[0028] The support member 7 is provided between the bottom plate 1 and the top plate 4 and is used to adjust the lifting of the top plate 4 and fix it. The support member 7 is not only used to adjust the lifting of the top plate 4, but also connected between the top plate 4 and the bottom plate 1 without affecting the expansion adjustment of the first expansion plate 2 and the second expansion plate 5;

[0029] In this solution, two first expansion plates 2 are slidably inserted on the bottom plate 1, and two second expansion plates 5 are slidably inserted on the top plate 4. A support member 7 is arranged between the bottom plate 1 and the top plate 4 for adjusting the lifting and lowering of the top plate 4. A column 3 is arranged on the first expansion plate 2, and the second expansion plate 5 is slidably sleeved on the column 3. When the top plate 4 is lifted or lowered, the second expansion plate 5 slides along the column 3. At the same time, it is fixed by a self-locking member 6 after sliding, so that even after the top plate 4 is lifted or lowered and the second expansion plate 5 is expanded and adjusted, the second expansion plate 5 still has an effective support point. After expansion and adjustment, it can maintain effective stability, ensure its load-bearing performance, and thus improve practicality.

[0030] like Figure 4 As shown, in some embodiments, the self-locking member 6 includes a fixed block 601 fixed on the second expansion plate 5, a groove 602 is provided on one side of the fixed block 601, a conical block 603 is slidably inserted in the groove 602, a guide rod 604 is fixed on the conical block 603, and a limit spring 605 is installed between the conical block 603 and the inner wall of the groove 602 and is sleeved on the guide rod 604, and a plurality of conical grooves 606 are provided in an array along the height direction of the column 3, and the conical block 603 is plugged into the conical groove 606. In the initial state, under the elastic force of the limit spring 605, the conical block 603 is movably inserted into one of the conical grooves 6 06, at this time, the second expansion plate 5 cannot move downward, and the column 3 supports the second expansion plate 5. When it is necessary to adjust the second expansion plate 5 to rise, the second expansion plate 5 can be directly moved up by overlapping the inclined surfaces of the conical block 603 and the conical groove 606. The inclined surface of the conical groove 606 can directly resist the movement of the conical block 603. After moving up, it is automatically reset by the elastic force of the limit spring 605 to achieve automatic locking. When it is necessary to move down, it is only necessary to pull the guide rod 604. The overall structure of the self-locking part 6 can automatically lock when moving up without operating interference. Only when moving down, it is necessary to pull the guide rod 604, and the operation is simple and convenient, thereby improving practicality.

[0031] like Figure 4As shown, in some embodiments, a first sleeve 8 movably mounted on the guide rod 604 is fixed on the fixed block 601, and a second sleeve 9 is fixed on the guide rod 604. The opposite sides of the first sleeve 8 and the second sleeve 9 are both constructed with inclined surfaces. In order to make the device more reasonable, preferably, the guide rod 604 is rotatably connected to the conical block 603. Since it is necessary to release the lock of the self-locking parts 6 on both sides when moving downward, the first sleeve 8 and the second sleeve 9 are provided. Therefore, by setting the first sleeve 8 and the second sleeve 9, when it is necessary to release the self-locking, the guide rod 604 is pulled to make the conical block 603 disengage from the conical groove 606, and then the guide rod 604 is rotated to make the second sleeve 9 and the first sleeve 8 misaligned (that is, the tip of the inclined surface contacts the tip of the inclined surface), and the guide rod 604 can be temporarily fixed to facilitate the adjustment of the top plate 4 and the second expansion plate 5 to descend, thereby improving convenience.

[0032] like Figure 2 As shown, in some embodiments, the support member 7 includes a bidirectional screw rod 701, and both ends of the bidirectional screw rod 701 are threadedly sleeved with movable blocks 702, and the two opposite sides of the movable block 702 are respectively hinged to the top plate 4 and the bottom plate 1 with support rods 703. When it is necessary to adjust the lifting of the top plate 4, the bidirectional screw rod 701 is twisted to rotate, and under the action of the bidirectional thread, the two movable blocks 702 are driven to move synchronously in opposite directions, so that the support rods 703 on the opposite sides respectively pull or resist the bottom plate 1 and the top plate 4, thereby realizing the adjustment of the lifting of the top plate 4. The threaded cooperation between the bidirectional screw rod 701 and the movable block 702 is self-locking to ensure that the top plate 4 can be self-locked after the lifting and lowering is adjusted, and to ensure its stability after locking.

[0033] like Figure 1 As shown, in some embodiments, supports 10 are provided at the four corners of the bottom of the base plate 1, and universal self-locking wheels 11 are provided at the bottom of the two first expansion plates 2. The supports 10 are used to support the base plate 1. Through the provided universal self-locking wheels 11, the first expansion plate 2 can also be indirectly supported without affecting the sliding adjustment of the first expansion plate 2, so that the ground is used to effectively support the first expansion plate 2 to ensure the load-bearing performance of the second expansion plate 5.

[0034] like Figure 2As shown, in some embodiments, the column 3 includes a first column rod 301 fixed on the first expansion plate 2, the first column rod 301 is hinged with the second column rod 302, and the first column rod 301 is provided with a fixing piece 303. When the second column rod 302 rotates around the hinge point to be coaxial with the first column rod 301, the fixing piece 303 fixes the second column rod 302. The column 3 is hingedly connected by the first column rod 301 and the second column rod 302. When the scaffold is in use, the second column rod 302 is rotated around the hinge point and erected, and then the second column rod 302 is fixed by the fixing piece 303. At this time, the first column rod 301 is fixed to the first column rod 302. The column 301 and the second column 302 are fixed upright to facilitate guiding or supporting the second expansion plate 5. When the scaffolding is not in use, first adjust the top plate 4 and the second expansion plate 5 to descend so that the top plate 4 is close to the bottom plate 1, and the second expansion plate 5 slides from the second column 302 to the first column 301, and then release the fixation of the fixing piece 303, and rotate the second column 302 around the hinge point to reduce the overall occupied space. In order to ensure that the occupied space is reduced after the whole is folded, the hinge points of the first column 301 and the second column 302 of the columns 3 on both sides can be staggered by a certain height.

[0035] like Figure 5 As shown, in some embodiments, the fixing member 303 includes a socket 3031 provided on the second column 302, a slot 3032 provided on the first column 301, a rod 3033 movably inserted into the slot 3032 and engaged with the socket 3031, a resisting spring 3034 is connected between the rod 3033 and the inner wall of the slot 3032, a sliding groove 3035 connected to the slot 3032 is provided on one side of the first column 301, and an adjusting rod 3036 is connected to the rod 3033, the end of which slides through the sliding groove 3035. When the first column 301 and the second column 302 need to be released, the adjustment rod 3036 is first dialed to make it slide in the slide groove 3035, thereby driving the insertion rod 3033 to slide along the slot 3032 and squeeze the resistance spring 3034, thereby withdrawing the insertion rod 3033 from the socket 3031 to release the fixation of the second column 302. The method of fixing or releasing the fixation is relatively simple and convenient, thereby improving convenience.

[0036] like Figure 1 As shown, in some embodiments, a mounting groove is provided on the top plate 4, and a ladder 12 is movably inserted into the mounting groove. Preferably, the top end of the ladder 12 is constructed with a plug-in end, which is plugged into the mounting groove. The provided ladder 12 is convenient for assisting staff to climb up, and the ladder 12 can be removed from the top plate 4 when not in use.

[0037] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
