Description

Technical Field

[0001] This application relates to the field of scaffolding, and more specifically, to a building safety type scaffolding. Background Art

[0002] A scaffolding is a working platform erected to ensure the smooth progress of each construction process. When constructing inside a building, steel pipe scaffolding is usually required. Since the indoor scaffolding needs to meet the requirements of mobile operation, movable rollers are provided at the bottom of the steel pipe scaffolding. Although the movable rollers are equipped with a braking structure, their stability effect is poor. The patent document with the publication number CN218758603U in the prior art provides a safety type building scaffolding. In this device, the connection end between the support feet and the scaffold is a screw structure, and a thread groove meshing with the screw end is formed inside the scaffold. By rotating the screw end in the thread groove of the scaffold, the relative horizontal heights of the support feet, the inner shaft and the main column are adjusted and changed, and the relative height between the main column and the scaffold is adjusted to meet the use requirements of the scaffolding.

[0003] Regarding the above related technology, the inventor believes that the four sets of scaffolds on the device need to be rotated to achieve height adjustment. Although the braking effect can be improved, the contact area between the scaffold and the ground cannot be increased, and the stability is poor. Therefore, we propose a building safety type scaffolding. Utility Model Content

[0004] In order to improve the problems proposed in the above background art, this application provides a building safety type scaffolding, adopting the following technical solutions:

[0005] A building safety type scaffolding includes a scaffolding main body, and also includes a connecting sleeve rotatably connected to the legs of the scaffolding main body. A fixed seat is fixedly connected to the connecting sleeve. A rotating seat is rotatably connected inside the fixed seat. A support rod is slidably connected inside the rotating seat. One end of the support rod is hinged with a support plate. A pull rod is elastically connected to the rotating seat. A clamping plate A and a clamping plate B are fixedly connected to the pull rod. The clamping plate A is in clamping cooperation with the support rod, and the clamping plate B is in clamping cooperation with the fixed seat.

[0006] By adopting the above technical solutions, when pulling the pull rod away from the fixed seat, the clamping of the clamping plate B with the fixed seat is cancelled, the rotating seat can drive the support rod to rotate, the clamping of the clamping plate A with the support rod is cancelled, and the support rod can slide inside the rotating seat until the support plate contacts the ground. After releasing the pull rod, the pull rod resets, causing the clamping plate B to be clamped with the fixed seat to limit the rotation of the rotating seat, and the clamping plate A to be clamped with the support rod to limit the sliding of the support rod. The cooperation of multiple support rods and support plates increases the contact area with the ground and improves the stability.

[0007] Optionally, a reinforcing rod is fixedly connected between the connecting sleeve and the fixed seat.

[0008] By adopting the above technical solution, the reinforcing rod enhances the stability between the fixing seat and the connecting sleeve.

[0009] Optionally, the pull rod has a T-shaped structure, and a spring A is sleeved on the pull rod. The two ends of the spring A are respectively connected and fixed to the clamping plate A and the rotating seat.

[0010] By adopting the above technical solution, when the clamping plate A is clamped with the support rod, the spring A is in a compressed state. When the pull rod is pulled away from the rotating seat, the spring A continues to be compressed, driving the clamping plate A and the clamping plate B to move.

[0011] Optionally, a plurality of clamping grooves A are equidistantly formed on one side of the support rod, and the clamping plate A is in clamping fit with the clamping grooves A.

[0012] By adopting the above technical solution, when the clamping plate A is not clamped with the clamping grooves A, the support rod can slide in the rotating seat, driving the support plate to contact the ground. After the clamping plate A is clamped with the clamping grooves A, the support rod cannot slide, enabling the support plate to stably contact the ground.

[0013] Optionally, a plurality of clamping grooves B are equidistantly formed on the fixing seat, and the clamping plate B is in clamping fit with the clamping grooves B.

[0014] By adopting the above technical solution, when the clamping plate B is not clamped with the clamping grooves B, the rotating seat can drive the support rod to rotate, enabling the support rod to be inclined, increasing the contact area with the ground. After the clamping plate B is clamped with the clamping grooves B, the rotating seat cannot rotate, restricting the angle adjustment of the support rod.

[0015] Optionally, a plurality of limiting grooves are annularly and equidistantly formed at one end of the connecting sleeve. A connecting ring is provided on the upper side of the connecting sleeve. One side of the connecting ring is elastically connected to the main body of the scaffold through a spring B, and the other side is fixedly connected with a plurality of limiting rods, and the limiting rods are inserted into the limiting grooves in a matching manner.

[0016] By adopting the above technical solution, when the connecting ring rises and the limiting rod is not inserted into the limiting groove, the connecting sleeve can rotate on the leg, enabling the orientation of the support plate to be adjusted according to the use scenario.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. After pulling the pull rod away from the rotating seat, the rotating seat can drive the support rod to adjust the angle. At the same time, the support rod can slide in the rotating seat, driving the support plate to contact the ground. After the pull rod is reset, the clamping plate A is clamped with the support rod, and the clamping plate B is clamped with the fixing seat. Multiple support rods and support plates cooperate to increase the contact area with the ground, improving the stability of the main body of the scaffold, thereby enhancing safety.

[0019] 2. When the limiting rod is not inserted into the limiting groove through the rising connecting ring, the connecting sleeve can drive the supporting rod to rotate, so that the orientation of the supporting plate can be adjusted according to the ground conditions, improving the practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0026] Referring to Figures 1-4 , the present application includes a scaffolding main body 1, and also includes a connecting sleeve 2 rotatably connected to the legs of the scaffolding main body 1. A fixed seat 3 is fixedly connected to the connecting sleeve 2. A rotating seat 5 is rotatably connected inside the fixed seat 3. A supporting rod 6 is slidably connected inside the rotating seat 5. One end of the supporting rod 6 is hinged to a supporting plate 7. A pull rod 8 is elastically connected to the rotating seat 5. A clamping plate A 10 and a clamping plate B 12 are fixedly connected to the pull rod 8. The clamping plate A 10 is in clamping cooperation with the supporting rod 6, and the clamping plate B 12 is in clamping cooperation with the fixed seat 3. When the pull rod 8 is pulled away from the fixed seat 3, the clamping of the clamping plate B 12 with the fixed seat 3 is cancelled, and the rotating seat 5 can drive the supporting rod 6 to rotate. The clamping of the clamping plate A 10 with the supporting rod 6 is cancelled, and the supporting rod 6 can slide inside the rotating seat 5 until the supporting plate 7 contacts the ground. After the pull rod 8 is released, the pull rod 8 resets, so that the clamping plate B 12 is clamped with the fixed seat 3 to limit the rotation of the rotating seat 5, and the clamping plate A 10 is clamped with the supporting rod 6 to limit the sliding of the supporting rod 6. Multiple supporting rods 6 and supporting plates 7 cooperate to increase the contact area with the ground and improve the stability.

[0027] Referring to Figure 2, a reinforcing rod 4 is fixedly connected between the connecting sleeve 2 and the fixed seat 3, and the reinforcing rod 4 enhances the stability between the fixed seat 3 and the connecting sleeve 2.

[0028] Referring to Figure 3 , the pull rod 8 is in a T-shaped structure, a spring A9 is sleeved on the pull rod 8, and both ends of the spring A9 are fixedly connected to the clamping plate A10 and the rotating seat 5 respectively. When the clamping plate A10 is clamped with the support rod 6, the spring A9 is in a compressed state. When the pull rod 8 is pulled away from the rotating seat 5, the spring A9 continues to be compressed, driving the clamping plate A10 and the clamping plate B12 to move.

[0029] Referring to Figure 3 , a plurality of card slots A11 are equidistantly arranged on one side of the support rod 6, and the clamping plate A10 is in clamping fit with the card slots A11. When the clamping plate A10 is not clamped with the card slots A11, the support rod 6 can slide in the rotating seat 5, driving the support plate 7 to contact the ground. After the clamping plate A10 is clamped with the card slots A11, the support rod 6 cannot slide, making the support plate 7 stably contact the ground.

[0030] Referring to Figure 3 , a plurality of card slots B13 are equidistantly arranged on the fixed seat 3, and the clamping plate B12 is in clamping fit with the card slots B13. When the clamping plate B12 is not clamped with the card slots B13, the rotating seat 5 can drive the support rod 6 to rotate, so that the support rod 6 can be inclined, increasing the contact area with the ground. After the clamping plate B12 is clamped with the card slots B13, the rotating seat 5 cannot rotate, restricting the angle adjustment of the support rod 7.

[0031] Referring to Figure 4 , a plurality of limiting grooves 14 are equidistantly arranged in a ring shape at one end of the connecting sleeve 2. A connecting ring 15 is arranged on the upper side of the connecting sleeve 2. One side of the connecting ring 15 is elastically connected to the scaffold main body 1 through a spring B16, and the other side is fixedly connected with a plurality of limiting rods 17. The limiting rods 17 are inserted and matched with the limiting grooves 14. When the connecting ring 15 rises and the limiting rods 17 are not inserted into the limiting grooves 14, the connecting sleeve 2 can rotate on the leg, so that the orientation of the support plate can be adjusted according to the use scenario.

[0032] The implementation principle of a building safety type scaffold in the embodiment of the present application is as follows: Before the scaffold main body 1 is used, the pull rod 8 is pulled away from the fixed seat 3, the clamping plate A10 cancels the clamping with the card slots A11, and the clamping plate B12 cancels the clamping with the card slots B13. The rotating seat 5 can drive the support rod 6 to rotate into an inclined state. The support rod 6 can slide in the rotating seat 5 to make the support plate 7 contact the ground. Then the pull rod 8 is released, and the spring A9 drives the pull rod 8 to reset, so that the clamping plate A10 is clamped with the card slots A11, and the clamping plate B12 is clamped with the card slots B13. The cooperation between the support rod 6 and the support plate 7 increases the contact area for the scaffold main body 1 and improves the support stability.
