Description

Technical Field

[0001] This utility model relates to the field of stair suction cup bracket technology, specifically a stair suction cup bracket for roof installation. Background Technology

[0002] In building construction and roof maintenance, roof staircases serve as access facilities, and their installation stability and ease of construction directly affect work efficiency and personnel safety. Currently, existing roof staircase installation methods mainly rely on traditional bolt anchoring, on-site welding, or simple bracket splicing, which have some drawbacks: First, traditional bolt anchoring requires pre-drilling holes in the roof structure, which not only damages the original waterproof layer and structural integrity, easily leading to leakage risks, but also makes it difficult to adjust the drilling position once determined. Second, on-site welding fixing is a complex construction process, and the welded brackets cannot be repeatedly disassembled and reused. If simple bracket splicing is used, there is a lack of dedicated locking and anti-slip structures. Fixing is done only through a single support point or binding method. When facing uneven roof surfaces, it is difficult to accurately position the stairs, and relative sliding between the stairs and the brackets is easy. At the same time, the existing installation method lacks a convenient height adjustment mechanism. When there are differences in roof thickness or stairs specifications, additional adaptation parts need to be processed.

[0003] To address these issues, we designed a stair suction cup bracket for roof mounting. Utility Model Content

[0004] The purpose of this invention is to provide a stair suction cup bracket for roof installation, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a stair suction cup bracket for roof installation, including an upper clamp, a lower clamp, an electric suction cup, an anti-slip pad, a round-headed hexagonal screw, a threaded rod, a clamping plate, a wing nut, a hexagonal nut, and a staircase. The upper and lower clamps are detachably fixed by the round-headed hexagonal screw. The anti-slip pad is clamped on the inner side of the upper and lower clamps, which together grip the handle of the electric suction cup to achieve a stable connection between the clamp and the suction cup. The clamping plate is divided into upper and lower groups, with the two ends of the staircase placed between the upper and lower groups of clamping plates. The threaded rod runs longitudinally through the clamping plate, and the hexagonal nut is threaded onto the threaded rod to adjust the distance between the upper and lower clamping plates to adapt to the thickness of the staircase. The wing nut is threaded to the end of the threaded rod to lock the clamping plate and the staircase. The electric suction cup is used to adhere to the flat surface of the roof.

[0006] Furthermore, the anti-slip pads are respectively attached to the inner walls of the upper and lower clamps, and are tightly attached to the outer wall of the electric suction cup handle.

[0007] Furthermore, at least two round-headed hexagonal screws are provided, and the two round-headed hexagonal screws are symmetrically distributed along the mating edges of the upper and lower clamps.

[0008] Furthermore, the toothed rod is fixedly connected to the lower clamping plate, the upper end of the toothed rod passes through the upper clamping plate, and the hexagonal nut is located on the toothed rod above the upper clamping plate.

[0009] Furthermore, the electric suction cup is a vacuum electric suction cup, and the suction surface of the electric suction cup is provided with a sealing gasket.

[0010] Furthermore, the clamping plate is made of metal, and the side of the clamping plate that contacts the stairs has anti-slip ridges.

[0011] Furthermore, the gripping part of the wing nut is provided with anti-slip texture and is adapted to the thread of the toothed rod for locking.

[0012] Furthermore, both the upper and lower clamps are arc-shaped structures, and their curvature matches the outer circumferential curvature of the electric suction cup handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The clamp is detachable and fixed by symmetrically distributed screws. The anti-slip pad fits tightly against the clamp and the suction cup handle to increase friction. The clamp is passed through by a toothed rod. The hexagonal nut can be adjusted to fit the thickness of the stair. The wing nut can be manually locked. Finally, a double stable connection is achieved between the electric suction cup and the clamp, and between the stair and the clamp, which effectively prevents relative slippage and is suitable for the installation needs of different stair sizes.

[0014] 2. Hoist the entire structure to the predetermined position on the cleaned roof, so that the suction surface of the electric suction cup is in contact with the flat surface of the roof. Activate the suction function to generate vacuum suction force, and the sealing gasket fills the tiny gaps to enhance the sealing performance. The entire bracket can be firmly fixed without drilling holes in the roof, which not only protects the original waterproof layer and structural integrity of the roof, but also achieves the positioning of the bracket.

[0017] 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.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a stair suction cup bracket for roof installation, including an upper clamp 4, a lower clamp 7, an electric suction cup 8, an anti-slip pad 5, a round-headed hexagonal screw 6, a threaded rod 2, a clamping plate 9, a wing nut 1, a hexagonal nut 10, and a stair 3; the upper clamp 4 and the lower clamp 7 are detachably fixed by the round-headed hexagonal screw 6, and the anti-slip pad 5 is clamped on the inner side of the upper clamp 4 and the lower clamp 7, which together hold the handle of the electric suction cup 8 to achieve a stable connection between the clamp and the suction cup; the clamping plate 9 is divided into upper and lower groups, and the two ends of the stair 3 are placed between the upper and lower groups of clamping plates 9 respectively; the threaded rod 2 runs longitudinally through the clamping plate 9; the hexagonal nut 10 is threaded on the threaded rod 2 to adjust the distance between the upper and lower clamping plates 9 to adapt to the thickness of the stair 3; the wing nut 1 is threaded to the end of the threaded rod 2 to lock the clamping plate 9 and the stair 3; the electric suction cup 8 is used to adsorb onto the flat surface of the roof.

[0019] In practical implementation, the upper clamp 4 and lower clamp 7 are detachably fixed by round-headed hexagonal screws 6. Anti-slip pads 5 are clamped to hold the handle of the electric suction cup 8, forming a stable connection. The upper and lower clamping plates 9 clamp the two ends of the stair 3. The toothed rod 2 runs longitudinally through the clamping plates 9. The hexagonal nut 10 adjusts the spacing of the clamping plates 9, and the butterfly nut 1 locks the stair 3. Finally, the electric suction cup 8 is used to adhere to the flat surface of the roof to complete the overall fixation. In this setting, the electric suction cup 8 adopts an adsorption fixation, which does not require drilling holes in the roof, completely protecting the original waterproof layer and structural integrity of the roof. The adsorption position can be adjusted as needed. The upper clamp 4 and lower clamp 7 are detachably connected by round-headed hexagonal screws 6. The entire bracket has no welded structure, is easy to disassemble and assemble, and can be reused. The hexagonal nut 10 rotates along the thread of the toothed rod 2 to adjust the spacing of the upper and lower clamping plates 9. No additional parts need to be processed, so it can be adapted to roofs of different thicknesses and stair 3 of different specifications.

[0020] See Figure 1-5 The anti-slip pads 5 are respectively attached to the inner walls of the upper clamp 4 and the lower clamp 7, and are also tightly attached to the outer wall of the handle of the electric suction cup 8.

[0021] In practice, this design enhances the connection stability between the clamp and the electric suction cup 8 to prevent the clamp from loosening due to construction vibration or long-term use; at the same time, it increases the contact friction to prevent relative sliding between the clamp and the suction cup handle.

[0022] See Figure 1-5 At least two round-head hexagon socket screws 6 are provided, and the two round-head hexagon socket screws 6 are symmetrically distributed along the mating edge of the upper clamp 4 and the lower clamp 7.

[0023] In practice, this setting can evenly distribute the locking force, making the clamping force of the clamp on the handle of the electric suction cup 8 more balanced, avoiding the force concentration caused by fixing with a single round-headed hexagonal screw 6, and preventing the upper clamp 4 and lower clamp 7 from deforming.

[0024] See Figure 1-5 The toothed rod 2 is fixedly connected to the lower clamping plate 9, and the upper end of the toothed rod 2 passes through the upper clamping plate 9. The hexagonal nut 10 is located on the toothed rod 2 above the upper clamping plate 9.

[0025] In practice, rotating the hexagonal nut 10 will cause the upper clamping plate 9 to move up and down along the toothed rod 2 to adjust the spacing. This setting makes the height adjustment structure more stable and avoids the clamping plate 9 from shifting during the adjustment process.

[0026] See Figure 1-5 The electric suction cup 8 is a vacuum electric suction cup 8, and the suction surface of the electric suction cup 8 is equipped with a sealing gasket.

[0027] In practice, the electric suction cup 8 uses the principle of vacuum adsorption. The sealing gasket on the adsorption surface can fill the tiny gap between the suction cup and the roof to form a sealed space, which enhances the vacuum adsorption effect. This setting can further improve the adsorption force and sealing performance.

[0028] See Figure 1-5 The cladding 9 is made of metal, and the side of the cladding 9 that contacts the staircase 3 has anti-slip ridges.

[0029] In practice, the metal clamp 9 has a high load-bearing capacity, and the anti-slip ridges on the side in contact with the stair 3 can increase the friction between the clamp 9 and the surface of the stair 3. This feature can improve the load-bearing performance of the support.

[0030] See Figure 1-5 The gripping part of the wing nut 1 has anti-slip texture and is adapted to the thread of the toothed rod 2 for quick locking.

[0031] In practice, locking is achieved quickly by manual rotation. This feature allows workers to rotate the wing nut 1 without additional auxiliary tools, improving construction efficiency.

[0032] See Figure 1-5Both the upper clamp 4 and the lower clamp 7 are arc-shaped structures, and their curvature matches the outer circumference curvature of the handle of the electric suction cup 8.

[0033] In practice, this setting can increase the contact area between the upper clamp 4, the lower clamp 7, and the electric suction cup 8, disperse the clamping pressure, and avoid excessive local force causing handle deformation or clamp loosening.

[0034] Working principle: Before use, all electrical appliances inside and outside this device need to be connected to an external power source, or a battery pack needs to be installed in an area outside this device that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0035] In use, attach the anti-slip pads 5 to the inner walls of the upper clamp 4 and the lower clamp 7 respectively. Then, fasten the inner walls of the upper clamp 4 and the lower clamp 7 to the outer periphery of the handle of the electric suction cup 8. Use two symmetrically distributed round-headed hexagonal screws 6 to detachably fix the upper clamp 4 and the lower clamp 7, ensuring that the anti-slip pads 5 are tightly attached to the outer wall of the suction cup handle. Place the upper and lower sets of metal clamps 9 correspondingly, and place the two ends of the staircase 3 between the upper and lower clamps 9 respectively, so that the toothed rod 2 penetrates the upper clamp 9 longitudinally. Rotate the upper clamp 9. The hexagonal nut 10 drives the upper clamping plate 9 to move up and down along the toothed rod 2. The distance between the upper and lower clamping plates 9 is adjusted to match the thickness of the stair 3. Then, the butterfly nut 1 is manually rotated and locked. The anti-slip ridges on the contact surface of the clamping plate 9 increase the friction and achieve a firm fixation between the stair 3 and the clamping plate 9. The assembled structure is hoisted to the predetermined position after the roof is cleaned, so that the suction surface of the electric suction cup 8 is in contact with the flat surface of the roof. The suction function of the electric suction cup 8 is activated, so that the electric suction cup 8 generates a vacuum suction force and is firmly fixed to the roof.
