Description

Technical Field

[0001] The utility model relates to the technical field of support frames, and more specifically, it relates to a support frame for construction. Background Art

[0002] Support frames play a crucial role in the construction industry. They are widely used in various construction scenarios to ensure construction safety and improve construction efficiency.

[0003] Support frames will face different problems in different usage scenarios. On construction sites, height and stability are required. The design and erection of support frame schemes need to draw detailed structural design drawings and be reviewed by professionals. In cantilever operations, the support frame must be able to provide safe support without supporting the overall structure. The cantilever support frame is a common choice, but appropriate materials and structures need to be selected according to the actual engineering requirements, etc.

[0004] In interior decoration, support frames are mainly used for auxiliary work, such as ceiling installation, wall construction, etc. The height and size of the support frame need to comply with the limitations of the indoor space. The erection and demolition of indoor support frames need to be more flexible and convenient to adapt to different construction requirements and spatial changes. In the known prior art, the support frame with universal wheels makes the transfer of the support frame more convenient, and the universal wheels come with a braking function, which can stop the support frame from sliding during use. However, the braking function of the universal wheels may be in an unactivated or insecurely locked state during use, and in this case, sliding may occur during use, causing difficulties to the workers on the support frame.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a support frame for construction.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: A support frame for construction, including a working platform, a column body, and universal wheels. The working platform is foldable. A fixed seat is slidably connected to the column body above the universal wheels. A foot tube is rotatably connected to the bottom of the fixed seat. A foot pedal is rotatably connected to one side of the fixed seat. A sliding block is slidably connected to the column body below the fixed seat. A connecting member is rotatably connected to the sliding block on the column body. The other end of the connecting member away from the sliding block is rotatably connected to the foot tube. The foot tube unfolds as the sliding block slides down.

[0008] The utility model is further provided as: A limit ring is provided on the end face of the foot pedal away from the fixed seat, and a convex block detachably connected to the limit ring is provided on the column body.

[0009] The utility model is further configured such that a limiting block is fixedly connected to the outer peripheral wall of the column body near the universal wheel.

[0010] The utility model is further configured such that an anti-slip sleeve is detachably connected to the bottom of the foot tube.

[0011] The utility model is further configured such that after the foot tube is unfolded, the angle formed by its top end and the axis of the column body is set between 20° and 30°.

[0012] The utility model is further configured such that the number of the foot tubes is at least three.

[0013] In summary, the utility model has the following beneficial effects: Installing an additional support structure on the column body where the universal wheel is located can enhance the stability of the support frame at a specific position to a certain extent, improve the grip of the column body on the ground, and provide additional support force in the case of poor or malfunctioning braking function of the universal wheel, helping to reduce the risk of the support frame sliding. Moreover, setting the foot pedal can eliminate the need for manual sliding of the fixed seat by people, improving its convenience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will describe the present utility model in detail with reference to the drawings and embodiments.

[0019] A construction support frame, as Figure 1 - Figure 2As shown, a fixed seat 3 is slidably connected above the universal wheel 2 on the column 1. The bottom of the fixed seat 3 is rotatably connected to a foot tube 7. One side of the fixed seat 3 is rotatably connected to a foot pedal 4. A sliding block 5 is slidably connected below the fixed seat 3 on the column 1. A connecting piece 6 is rotatably connected to the sliding block 5 on the column 1. The other end of the connecting piece 6 away from the sliding block 5 is rotatably connected to the foot tube 7. The foot tube 7 unfolds as the sliding block 5 slides down. Installing an additional support structure on the column 1 where the universal wheel 2 is located can, to a certain extent, enhance the stability of the support frame at a specific position, improve the grip of the column 1 on the ground, and provide additional support force in the case of poor or malfunctioning braking function of the universal wheel 2, helping to reduce the risk of the support frame sliding.

[0020] As Figure 1 - Figure 3 shown, an opening 10 is provided in the upper part of one side of the fixed seat 3. The foot pedal 4 can rotate to a position above the fixed seat 3. A limiting ring 8 is provided on the end face of the side of the foot pedal 4 away from the fixed seat 3. And a convex block 9 matching the limiting ring 8 is provided on the column 1 facing the rotating side of the foot pedal 4. When the foot pedal 4 rotates towards the column 1, the convex block 9 can be sleeved into the limiting ring 8, and the foot pedal 4 cannot rotate downward. This setting can realize the foot pedal 4 driving the fixed seat 3 and the sliding block 5 to slide down, and at the same time realize the limiting function of the fixed seat 3, improving its operation convenience. The bottom of the foot tube 7 is detachably connected with an anti-slip sleeve. The material of the anti-slip sleeve is preferably rubber. Rubber has excellent elasticity and anti-slip performance. It can reduce the risk of slipping by increasing the friction and elasticity of the ground, and increase the stability of the structure. When the working platform changes from the folded state to the unfolded state and is placed at the position where it is needed, lock and fix the universal wheel 2, then adjust the position of the fixed seat 3, and at the same time unfold the foot tube 7. The number of the foot tubes 7 is set to at least 3. After unfolding, a more stable triangular structure can be formed to improve its stability. After the foot tube 7 is unfolded, the bottom surface of the foot tube 7 abuts against the ground. After the foot tube 7 unfolds outward, the angle formed with the column 1 is set at 20 - 30 degrees. This angle can ensure the stability of the support structure. When the foot tube 7 unfolds, since the foot tube 7 is rotatably connected to the sliding block 5 through the connecting piece 6, when the foot tube 7 unfolds, the sliding block 5 slides down, and at the same time the connecting piece 6 rotates. At this time, the included angle formed by the connecting piece 6 and the column 1 becomes larger. To prevent the continuous sliding of the sliding block 5, a limiting block 14 is sleeved below the sliding block 5 on the column 1. The position of the limiting block 14 is fixed. When the bottom surface of the sliding block 5 slides down and abuts against the top surface of the limiting block 14, the bottom surface of the foot tube 7 can abut against the ground.

[0021] Working principle: The working platform is formed by hinge - connecting several support plates 11. The support plates 11 at both ends are rotatably connected to the column 1 to achieve the folding function. In addition to the column 1 serving as a support point, a support column 12 is rotatably connected between two adjacent columns 1. The setting of the support column 12 can increase support points in addition to the column 1 to improve the stability of its overall structure. A universal wheel 2 is installed at the bottom end of the column 1, which can improve its usability and make it more labor - saving. An expansion rod 13 is connected between the support columns 12 on the opposite sides. When the support plates 11 are folded together, the expansion rod 13 contracts, and the support column 12 rotates inward, and the columns 1 approach each other. When the support plates 11 are unfolded, the expansion rod 13 stretches, and the support column 12 rotates outward until it is in the same plane as the two columns 1. At this time, the length of the expansion rod 13 is fixed. The setting of the expansion rod 13 can further ensure the stability of the overall structure. When this support frame needs to be used, unfold the support plates 11 at the place of use, and at the same time pull open the column 1 and the support column 12, lock the universal wheel 2, then step on the foot - stepping block 4 to slide the fixed seat 3, unfold the foot tube 7 so that the bottom surface of the foot tube 7 abuts against the ground. At the same time, the sliding block 5 also slides to abut against the limit block 14 and stops sliding. Then turn the foot - stepping block 4 upward and fix the position of the fixed seat 3 through the socket connection of the convex block 9 and the limit ring 8, so that the foot tube 7 plays a role in increasing the friction with the ground to prevent slipping. Ensure that during use, when the braking function of the universal wheel 2 fails or weakens and the universal wheel 2 slides, this structure can reduce the danger caused by sliding to a certain extent. Wait for the staff to realize and get off the support frame, maintain or repair the braking system of the universal wheel 2. After the repair is completed, slide the fixed seat 3 again, retract the foot tube 7 so that the foot tube 7 leaves the ground and is fixed at the position above the universal wheel 2 through the fixed seat 3. Then fold the support plates 11 again, push the column 1 to make the support column 12 rotate inward, and retract the expansion rod 13. After that, the entire support frame can be pushed by the universal wheel 2 for storage and arrangement.

The protection scope of the present utility model is not limited to the above - mentioned embodiments. All technical solutions within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
