Description

Technical Field

[0001] This utility model relates to the technical field of movable frame support, specifically a leg stabilization mechanism for a movable frame. Background Technology

[0002] A mobile scaffold is a frame structure that is movable and commonly used in construction to build temporary work platforms. Construction workers use mobile scaffolds to build temporary work platforms for high-altitude operations, such as painting and bricklaying walls, as well as ceiling decoration and drilling. Mobile scaffolds can provide construction workers with a safe and stable working platform, improving construction efficiency and safety.

[0003] To meet the need for flexible movement of mobile racks, existing mobile racks are generally equipped with casters at the bottom. The use of casters allows the mobile rack to move easily in all directions, greatly improving its mobility. Some mobile racks use self-locking casters. When the mobile rack moves to the designated position, locking the casters can prevent the mobile rack from sliding at will to a certain extent, so as to make it easier to fix.

[0004] In pursuit of a compact structure and a small footprint, existing mobile frames typically have relatively small wheel spacing. This results in a high center of gravity when the mobile frame is in use. When construction workers operate on the mobile frame, the center of gravity changes with the movement of the workers. If the center of gravity deviates from the support range of the casters, the mobile frame will lose balance, greatly increasing the risk of workers falling from heights. To address this issue, we have provided a leg stabilization mechanism for the mobile frame. Utility Model Content

[0006] This utility model proposes a leg stabilization mechanism for a movable frame. By setting up support mechanisms and other components, it solves the problem that the existing movable frames have a high center of gravity, are prone to losing balance, and greatly increase the risk of construction workers falling from heights.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a leg stabilizing mechanism for a movable frame, comprising a support leg, a movable frame mounted on the upper part of the support leg, a caster wheel fixedly mounted on the lower end of the support leg, a movable rod provided on the outside of the support leg, a limiting mechanism provided between the movable rod and the support leg, the limiting mechanism being used to limit the movable rod to ensure that the movable rod can only rotate around the support leg; a connecting mechanism provided on the outer surface of the movable rod, a supporting mechanism provided at the end of the connecting mechanism away from the movable rod, the supporting mechanism providing support and fixing to the movable frame through contact with the ground; a locking mechanism provided at the upper end of the movable rod, the locking mechanism being used to lock the movable rod at a specific fixed position, thereby ensuring that the movable rod remains stable in the required position.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, the leg stabilization mechanism of this movable frame has the following advantages:

[0017] I. The leg stabilization mechanism of this mobile frame, through the setting of support mechanisms and other components, connects the movable rod to the support mechanism. The connecting mechanism increases the distance between the support mechanism and the movable rod, naturally placing the support mechanism on the outside of the support leg and maintaining a certain distance from it. The support mechanism replaces the casters to support the whole structure, thereby increasing the support coverage area and enhancing stability. This solves the problem of the existing high center of gravity, which makes the mobile frame prone to losing balance and greatly increases the risk of construction workers falling from heights.

[0018] Second, the leg stabilization mechanism of this mobile frame, through the setting of locking mechanisms and other components, restricts the rotation angle of the movable rod, thereby fixing the support mechanism. When moving, the support mechanism and other components are folded up to reduce the volume occupied, while realizing the functions of easy folding and opening and support, which is suitable for the use of small mobile frames.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a leg stabilizing mechanism for a movable frame, including a support leg 1, a movable frame 2 mounted on the upper part of the support leg 1, and a caster wheel 3 fixedly mounted on the lower end of the support leg 1. A movable rod 4 is provided on the outside of the support leg 1, and a limiting mechanism 5 is provided between the movable rod 4 and the support leg 1. This limiting mechanism 5 is used to limit the movement of the movable rod 4, thereby ensuring that the movable rod 4 can only rotate around the support leg 1. A connecting mechanism 6 is provided on the outer surface of the movable rod 4, and a support mechanism 7 is provided at the end of the connecting mechanism 6 away from the movable rod 4. The support mechanism 7 achieves the function of supporting and fixing the movable frame 2 through contact with the ground. A locking mechanism 8 is provided at the upper end of the movable rod 4, which is used to lock the movable rod 4 at a specific fixed position, thereby ensuring that the movable rod 4 remains stable in the required position. The support leg 1, the upper movable frame 2, and the lower caster wheel 3 are existing technologies. In practice, the caster wheel 3 facilitates the movement of the support leg 1 for pushing it. The device is placed in a suitable position for use. However, due to the height of the movable frame 2, it is prone to instability. Therefore, a movable rod 4 is added based on the existing technology. The movable rod 4 is connected to the support mechanism 7 through the connecting mechanism 6. The connecting mechanism 6 increases the distance between the support mechanism 7 and the movable rod 4, naturally placing the support mechanism 7 on the outside of the support leg 1 and maintaining a certain distance from it. The support mechanism 7 replaces the casters 3 to support the whole, thereby increasing the support coverage area and improving stability. At the same time, the locking mechanism 8 restricts the rotation angle of the movable rod 4, fixing the support mechanism 7. When moving, the support mechanism 7 and other components are folded up to reduce the volume occupied. Compared with the support devices on large equipment, this device does not use any electrical devices, reducing its weight and cost. It also achieves the functions of easy folding, opening, and support, making it suitable for use in small movable frames. After folding, the movable rod 4 can be tied with the rope 9 to further increase the fixation effect.

[0028] The limiting mechanism 5 includes a rotating block 501, which is fixedly connected to the outer surface of the movable rod 4. The inner wall of the rotating block 501 is rotatably connected to the support leg 1. The outer surface of the support leg 1 is fixedly connected to a limiting shaft 502. The outer surface of the limiting shaft 502 is slidably connected to the rotating block 501. There are multiple limiting shafts 502, which are respectively set at the upper and lower positions of the rotating block 501 to hold the rotating block 501 in place and prevent it from moving up and down. At the same time, the arrangement of the positions prevents it from contacting and jamming with the movable rod 4. When the movable rod 4 rotates, it can drive the rotating block 501 to rotate.

[0029] The support mechanism 7 includes a sleeve 701, with a threaded rod 702 threadedly connected to the inner wall of the sleeve 701. A rotating disk 703 is fixedly connected to the upper end of the threaded rod 702, and a base plate 704 is rotatably connected to the lower end of the threaded rod 702. By rotating the threaded rod 702 through the rotating disk 703, the threaded rod 702 can move up or down, thereby adjusting the height of the base plate 704. When support is needed, the base plate 704 is made to fully contact the ground for pressure support. When moving, the base plate 704 is separated from the ground, allowing the casters 3 to be supported by pressure.

[0030] The connecting mechanism 6 includes a fixed rod 601. One end of the fixed rod 601 is fixedly connected to the movable rod 4, and the other end of the fixed rod 601 is fixedly connected to the sleeve 701. The movable rod 4 and the sleeve 701 are fixed by the fixed rod 601.

[0031] The connecting mechanism 6 also includes a reinforcing rod 602. One end of the reinforcing rod 602 is fixedly connected to the sleeve 701, and the other end is fixedly connected to the movable rod 4. The reinforcing rod 602 is inclined and is used to further increase the fixing effect between the sleeve 701 and the movable rod 4 to increase stability.

[0032] The locking mechanism 8 includes a fixing plate 801. The inner wall of the fixing plate 801 is fixedly connected to the support leg 1. The inner wall of the fixing plate 801 is provided with fixing holes 802. There are two fixing holes 802. The two fixing holes 802 form a 155-degree angle with the center of the fixing plate 801 as the center.

[0033] The upper end of the movable rod 4 is slidably connected to a plug rod 803. The outer surface of the plug rod 803 passes through the fixing hole 802. The lower surface of the plug rod 803 is fixedly connected to a sliding plate 804. The lower surface of the sliding plate 804 is fixedly connected to a spring 805. The lower end of the spring 805 is fixedly connected to the movable rod 4. The outer surface of the sliding plate 804 is fixedly connected to a lever 806. In use, the plug rod 803 is inserted into the fixing hole 802 to fix the movable rod 4. Pressing the lever 806 downwards can move the plug rod 803 downwards to release the restriction and facilitate the rotation of the movable rod 4.

[0034] Working principle: After the movable frame 2 moves to the designated working position, manually press down the lever 806. The lever 806 drives the sliding plate 804, which is fixedly connected to it, to move downwards synchronously. The sliding plate 804 compresses the spring 805 at its lower end, releasing the rotation restriction on the movable rod 4 and pushing the movable rod 4 to rotate outwards around the support leg 1. Then, the sliding plate 804 and the insertion rod 803 return to their original position. The insertion rod 803 inserts into another fixing hole 802, locking the movable rod 4 again and keeping it at the same support angle. Manually rotate the rotating disk 70. 3. The rotating disk 703 drives the threaded rod 702 to move downward along the inner wall of the sleeve 701. The bottom plate 704, which is rotatably connected to the lower end of the threaded rod 702, descends accordingly until it is in complete contact with the ground. The height of the bottom plate 704 is adjusted according to the flatness of the ground to ensure that the bottom plate 704 is evenly stressed. At the same time, the movable frame 2 is kept horizontal. At this time, the overall load of the movable frame 2 is transferred from the casters 3 to the bottom plate 704. The support mechanism 7 expands the support radius through the connecting mechanism 6, increases the support coverage area, lowers the overall center of gravity height, and improves stability.

[0035] After the operation is completed, rotate the rotating disk 703 to move the threaded rod 702 upward, causing the base plate 704 to lift off the ground and be stored; press down the lever 806 to unlock the locking mechanism 8, and push the movable rod 4 to rotate inward to reset.

[0036] When the movable rod 4 is rotated to the folded position, the insertion rod 803 is inserted into the fixing hole 802 under the action of the spring 805, and the locking is completed. Finally, the movable rod 4 is bound by the binding rope 9, and the initial moving state is restored.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
