Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to an indoor scaffold for building construction. Background Art

[0002] Scaffolding is a temporary structure used to support and provide a working platform. It is usually used in construction, maintenance, decoration and other projects. In order to ensure the safety of construction workers when using the scaffolding, it is usually necessary to keep the scaffolding stable during use.

[0003] The Chinese patent "An indoor scaffold for house construction" authorization announcement number "CN 215631446U" fixes universal wheels at the four corners of the bottom of the base to facilitate the movement of the scaffold. At the same time, when in use, the turntable of the anti-slip mechanism on the base is rotated, and the turntable rotates with the screw. The rotating screw pushes the bottom plate to fit tightly with the ground to prevent the device from moving when in use.

[0004] Although the scaffolding can be fixed in the above application, when the bottom plate is fixed in contact with the ground, the universal wheels are still in contact with the ground, which increases the instability during fixation. At the same time, the contact area between the bottom plate and the ground is small, which has a poor fixing effect on the scaffolding.

[0005] Therefore, an indoor scaffold for building construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an indoor scaffold for construction in order to solve the above-mentioned problem, which improves the problem that when the base plate is fixed in contact with the ground, the universal wheels are still in contact with the ground, which increases the instability during fixing. At the same time, the contact area between the base plate and the ground is small, which has a poor fixing effect on the scaffold.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: an indoor scaffold for building construction, comprising: a scaffold body, the bottom end of the scaffold body is fixedly connected to a base plate, and the bottom end of the base plate is provided with a fixing mechanism; wherein the fixing mechanism comprises four fixing rods respectively fixedly connected to the four corners of the bottom end of the base plate, the bottom ends of the fixing rods are fixedly connected to a fixing frame, the inner wall of the fixing rod is slidably connected to a round rod, the bottom end of the round rod penetrates to the inner side of the fixing frame and is fixedly connected to a universal wheel, the inner wall of the base plate is rotatably connected to a bolt, the surface of the bolt is threadedly connected to a moving rod, both ends of the moving rod are fixedly connected to a mounting plate, the two ends of the mounting plate respectively penetrate to the inside of two horizontal fixing rods and are fixedly connected to the surface of the corresponding round rod, and a reinforcement component is provided inside the fixing frame.

[0008] Preferably, the reinforcement assembly includes two movable plates slidably connected to the upper end of the inner wall of the fixed frame, one side of the movable plate passes through the fixed frame and is fixedly connected to a connecting plate, two reinforcement plates are slidably connected to both sides of the inner wall of the fixed frame, one side of the reinforcement plate passes through the fixed frame, and one side of the two reinforcement plates is longitudinally fixedly connected to the lower end of one side of the corresponding connecting plate. This is conducive to driving the reinforcement plates to move away from the fixed frame at the same time, thereby increasing the contact area when the fixed frame is fixed to the ground, increasing the overall force-bearing area of ​​the device, and enhancing the stability of the scaffold body when it is fixed.

[0009] Preferably, the reinforcement assembly further comprises a connecting rod hinged to the bottom end of the movable plate, the other end of the connecting rod is hinged to a trigger rod, the bottom end of the trigger rod passes through the fixed frame, the upper surface of the trigger rod is fixedly connected to a fixed block, the bottom end of the fixed block is fixedly connected to a spring, the other end of the spring is fixedly connected to the inner wall of the fixed frame. Under the action of the two trigger rods and the corresponding connecting rods, it is conducive to pushing the two movable plates to move in opposite directions at the same time.

[0010] Preferably, the bottom end of the fixing frame is provided with grooves distributed in equal rows, and an angle is formed between the grooves and the vertical surface, which is beneficial to increase the friction force when the fixing frame contacts the ground.

[0011] Preferably, the bottom end of the fixing frame is provided with two circular grooves, the centers of the circular grooves and the centers of the corresponding trigger rods are on the same vertical plane. When the fixing frame is fixed to the ground, it is beneficial to shrink the bottom end of the trigger rod into the circular groove, thereby ensuring the stability of the fixing frame when it is fixed.

[0012] Preferably, the bottom end of the reinforcing plate is on the same horizontal plane as the bottom end of the fixing frame, which helps to ensure that the reinforcing plate is in contact with the ground while the fixing frame is in contact with the ground.

[0013] Preferably, a limiting block is fixedly connected to the surface of the reinforcement plate, and the surface of the limiting block is slidably connected to the inner wall of the fixed frame, which is conducive to limiting the movement of the reinforcement plate.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4 As shown, an indoor scaffold for building construction, the utility model achieves the above-mentioned purpose through the following technical solutions, an indoor scaffold for building construction, comprising: a scaffold body 1, the bottom end of the scaffold body 1 is fixedly connected to a base plate 2, and the bottom end of the base plate 2 is provided with a fixing mechanism 3; wherein the fixing mechanism 3 comprises four fixing rods 301 respectively fixedly connected to the four corners of the bottom end of the base plate 2, the bottom end of the fixing rod 301 is fixedly connected to a fixing frame 302, the inner wall of the fixing rod 301 is slidably connected to a round rod 303, the bottom end of the round rod 303 penetrates to the inner side of the fixing frame 302 and is fixedly connected to a universal wheel 304, the inner wall of the base plate 2 is rotatably connected to a bolt 305, the surface of the bolt 305 is threadedly connected to a moving rod 306, both ends of the moving rod 306 are fixedly connected to a mounting plate 307, the two ends of the mounting plate 307 respectively penetrate to the inside of the two horizontal fixing rods 301 and are fixedly connected to the surface of the corresponding round rod 303, and a reinforcement component 308 is provided inside the fixing frame 302.

[0024] The scaffold body 1 is an existing structure. When the device is in use, when the scaffold body 1 needs to be moved, the bolt 305 is rotated clockwise to drive the moving rod 306 to move downward, and the two mounting plates 307 are driven to move downward synchronously. At this time, the two mounting plates 307 will simultaneously push the corresponding two round rods 303 to move downward, so that the four round rods 303 simultaneously push the corresponding universal wheels 304 to move downward. When the universal wheels 304 are in contact with the ground, the bolt 305 is continued to be rotated. Under the action of the resistance force between the universal wheels 304 and the ground, the fixed frame 302 will be released from contact with the ground. At this time, the scaffold body 1 can be moved using the universal wheels 304.

[0025] When the scaffold body 1 needs to be fixed for use, the bolt 305 is turned counterclockwise. At this time, under the action of the moving rod 306 and the mounting plate 307, the round rod 303 is driven to move in the opposite direction, so that the round rod 303 drives the universal wheel 304 to move toward the inside of the fixed frame 302. When the universal wheel 304 is completely moved to the inside of the fixed frame 302 and fixed, at this time, the bottom ends of the four fixed frames 302 are in contact with the ground at the same time.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the reinforcement assembly 308 includes two moving plates 3081 slidably connected to the upper end of the inner wall of the fixed frame 302, one side of the moving plate 3081 penetrates the fixed frame 302 and is fixedly connected to the connecting plate 3082, two reinforcing plates 3083 are slidably connected to both sides of the inner wall of the fixed frame 302, one side of the reinforcing plate 3083 penetrates the fixed frame 302, and one side of the two longitudinal reinforcing plates 3083 is fixedly connected to the lower end of one side of the corresponding connecting plate 3082. The reinforcement assembly 308 also includes a connecting rod 3085 hinged to the bottom end of the moving plate 3081, the other end of the connecting rod 3085 is hinged to a trigger rod 3084, the bottom end of the trigger rod 3084 penetrates the fixed frame 302, the upper surface of the trigger rod 3084 is fixedly connected to a fixing block 3086, the bottom end of the fixing block 3086 is fixedly connected to a spring 3087, and the other end of the spring 3087 is fixedly connected to the inner wall of the fixed frame 302. The bottom end of the reinforcing plate 3083 and the bottom end of the fixing frame 302 are on the same horizontal plane.

[0027] When the universal wheel 304 moves toward the inside of the fixed frame 302, the fixed frame 302 will move downward and drive the trigger rod 3084 to move downward synchronously. When the universal wheel 304 contacts the ground and moves the scaffold body 1, there is a certain distance between the bottom end of the trigger rod 3084 and the ground. When the universal wheel 304 moves upward for a certain distance, the bottom end of the trigger rod 3084 contacts the ground, and the universal wheel 304 continues to move upward. At this time, the distance between the fixed frame 302 and the ground will gradually decrease, so that the trigger rod 3084 84 is squeezed and moves toward the inside of the fixed frame 302, the spring 3087 is pulled up, and when the trigger rod 3084 moves upward, it will drive the other end of the connecting rod 3085 to move upward synchronously, and one end of the connecting rod 3085 pushes the movable plate 3081 to move horizontally in the direction away from the fixed frame 302. At this time, under the action of the two trigger rods 3084, the two connecting plates 3082 will simultaneously drive the corresponding reinforcement plates 3083 to move in the direction away from the fixed frame 302, thereby increasing the contact area between the fixed frame 302 and the ground.

[0028] like Figure 3 As shown, the bottom end of the fixing frame 302 is provided with grooves 309 distributed in equal rows, and an angle is formed between the grooves 309 and the vertical plane. The grooves 309 are distributed in equal rows in an inclined direction.

[0029] like Figure 3 As shown, two circular grooves 3089 are formed at the bottom of the fixed frame 302, and the centers of the circular grooves 3089 and the centers of the corresponding trigger rods 3084 are on the same vertical plane. When the bottom of the fixed frame 302 contacts the ground, the bottom of the trigger rod 3084 will shrink into the circular grooves 3089.

[0030] like Figure 4As shown, the surface of the reinforcing plate 3083 is fixedly connected to the limiting block 3088, and the surface of the limiting block 3088 is slidably connected to the inner wall of the fixed frame 302. The inner wall of the fixed frame 302 is provided with a limiting groove matching the limiting block 3088, and the surface of the limiting block 3088 is slidably connected to the inner wall of the limiting groove.

[0031] When the utility model is in use, when the scaffold body 1 needs to be fixed for use, the bolt 305 is rotated counterclockwise, and the round rod 303 is driven to move in the opposite direction under the action of the moving rod 306 and the mounting plate 307, so that the round rod 303 drives the universal wheel 304 to move toward the inner side of the fixed frame 302. In the process of the universal wheel 304 moving toward the inner side of the fixed frame 302, the fixed frame 302 will move downward and drive the trigger rod 3084 to move downward synchronously. After the universal wheel 304 moves upward for a certain distance, the bottom end of the trigger rod 3084 will contact the ground, and the universal wheel 304 will continue to move upward. At this time, the trigger rod 3084 will be squeezed and moved toward the inner side of the fixed frame 302. When the trigger rod 3084 moves upward, the spring 3087 is pulled up, and when the trigger rod 3084 moves upward, it will drive the other end of the connecting rod 3085 to move upward synchronously, so that the connecting rod 3085 pushes the movable plate 3081 to move horizontally in the direction away from the fixed frame 302. At this time, under the action of the two trigger rods 3084, the two connecting plates 3082 will simultaneously drive the corresponding reinforcement plates 3083 to move in the direction away from the fixed frame 302. When the universal wheel 304 is completely moved to the inner side of the fixed frame 302 and fixed, the bottom ends of the four fixed frames 302 and the bottom ends of the corresponding reinforcement plates 3083 will contact the ground at the same time, thereby increasing the stability of the scaffold body 1 when used.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
