Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, it relates to an adjustable interior building edge guardrail. Background Art

[0002] In building construction, the edge environment is one of the hazard sources. The safety issue of the building construction site is an essential task for us. To ensure the safety of construction workers, in the building construction edge area, a special protective facility - an edge guardrail needs to be set up.

[0003] As retrieved, the existing related patent: CN212027389U discloses a building construction edge guardrail net. This existing technology has the advantage that the length of the guardrail can be adjusted by setting a horizontal telescopic rod and an adjustable grid.

[0004] However, the inventor believes that the existing technology design has the following drawbacks: After the adjustable grid in the existing technology is stretched, the sliding block will move upward, which causes the hinged part on the lower side of the adjustable grid to also move upward. The longer the pull, the larger the gap at the bottom. In this way, the bottom of the existing guardrail lacks a blocking structure, and the adjusted adjustable grid cannot effectively protect the building construction environment, reducing the protection effect of the edge guardrail. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an adjustable interior building edge guardrail.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An adjustable interior building edge guardrail includes two vertically parallel columns. Two sliding sleeves are slidably sleeved on the outer surfaces of the two columns. An adjustable grid is arranged between the two sliding sleeves. A plurality of hinge seats are arranged on the adjustable grid. Sleeve housings and horizontal sliding plates are arranged on the opposite surfaces of the two columns. The sleeve housings are slidably sleeved on the outer surfaces of the horizontal sliding plates. Limiting housings are arranged on the hinge seats. Extendable limiting rods are arranged on the limiting housings. Contact balls are arranged at the upper ends of the limiting rods. The contact balls close to the horizontal sliding plates are in contact with and slide on the lower surfaces of the horizontal sliding plates. The contact balls close to the sleeve housings are in contact with and slide on the lower surfaces of the sleeve housings.

[0008] The utility model is further arranged as follows: Bases are arranged at the lower ends of the two columns, and bolts for fixing are arranged on the bases.

[0009] The present utility model is further configured as follows: The adjustable grid includes two first rotating plates and two second rotating plates. One side of the first rotating plate adjacent to the second rotating plate is hinged to the outer surface of the sliding sleeve.

[0010] The present utility model is further configured as follows: The lower side of the third rotating plate close to the column is hinged to the outer surface of the column.

[0011] The present utility model is further configured as follows: A plurality of the hinge seats are respectively arranged on the upper sides of two adjacent third rotating plates and on the upper sides of the second rotating plate and the third rotating plate.

[0012] The present utility model is further configured as follows: One end of the limiting rod close to the limiting housing slides through the limiting housing. One end of the limiting rod located inside the limiting housing is provided with an internal sliding plate that slides inside the limiting housing.

[0013] The present utility model is further configured as follows: A tension spring is arranged between the internal sliding plate and the inner wall of the limiting housing, and the tension spring is movably sleeved on the outer surface of the limiting rod.

[0014] The present utility model is further configured as follows: A plurality of limiting grooves are formed in the transverse sliding plate.

Specific implementation manner

[0023] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0024] Specifically, it refers to an adjustable edge protection railing inside a building, including two columns 1 arranged horizontally and parallel to each other. The lower ends of both columns 1 are provided with bases 2. The bases 2 are provided with bolts for fixing the entire device on the building floor. Two sliding sleeves 3 are slidably sleeved on the outer surfaces of the two columns 1. The opposite surfaces of the two sliding sleeves 3 are respectively hinged with a first rotating plate 4 and a second rotating plate 5. A plurality of third rotating plates 6 arranged crosswise are provided between the two groups of first rotating plates 4 and second rotating plates 5 on the left and right sides. The lower side of the third rotating plate 6 close to the column 1 is hinged to the outer surface of the column 1. Hinge seats 7 are provided on the upper sides of adjacent two third rotating plates 6 and on the upper sides of the second rotating plate 5 and the third rotating plate 6. The first rotating plate 4, the second rotating plate 5 and the third rotating plate 6 are combined into a diamond-shaped telescopic frame. Therefore, when the distance between the two columns 1 is stretched, the first rotating plate 4, the second rotating plate 5 and the third rotating plate 6 rotate in opposite directions, and at the same time, the sliding sleeve 3 moves downward on the column 1. When the distance between the two columns 1 is contracted, the first rotating plate 4, the second rotating plate 5 and the third rotating plate 6 rotate in opposite directions, and at the same time, the sliding sleeve 3 moves upward on the column 1. In this way, the length of the protection railing can be adjusted according to the environment at the edge of different building construction sites, ensuring the use effect of the protection railing.

[0025] A sleeved housing 11 and a transverse sliding plate 12 are arranged on the opposite surfaces of the two columns 1. The sleeved housing 11 is slidably sleeved on the outer surface of the transverse sliding plate 12. In this way, when the distance between the two columns 1 is adjusted, the transverse sliding plate 12 slides in the sleeved housing 11.

[0026] A limiting housing 8 is provided on the hinged seat 7, an extendable limiting rod 9 is provided on the limiting housing 8, a contact ball 10 is provided at the upper end of the limiting rod 9. The contact ball 10 close to the transverse slide plate 12 contacts and slides on the lower surface of the transverse slide plate 12, and the contact ball 10 close to the sleeved housing 11 contacts and slides on the lower surface of the sleeved housing 11. In this way, when the sliding sleeve 3 moves downward, the limiting rod 9 extends, so that the contact ball 10 always contacts the lower surface of the transverse slide plate 12 or the sleeved housing 11. In this way, when the guardrail is stretched, there will be no problem of upper and lower gaps in the adjustable grid, further ensuring the protection effect of the guardrail.

[0027] One end of the limiting rod 9 close to the limiting housing 8 slides through the limiting housing 8. An internal slide plate 13 that slides in the limiting housing 8 is provided at the end of the limiting rod 9 located inside the limiting housing 8. A tension spring 14 that is movably sleeved on the outer surface of the limiting rod 9 is provided between the internal slide plate 13 and the inner wall of the limiting housing 8. When the two columns 1 are close to each other, the hinged seat 7 pushes the limiting housing 8 to move to the top side. At this time, the sleeved housing 11 and the transverse slide plate 12 will squeeze the contact ball 10, so that the contact ball 10 is on the side close to the limiting housing 8. At the same time, the tension spring 14 is pulled by the internal slide plate 13 and is in a stretched state. In this way, when the distance between the two columns 1 is stretched, the hinged seat 7 moves downward. At this time, the contact ball 10 is always in contact with the lower surface of the sleeved housing 11 or the transverse slide plate 12 under the pull of the tension spring 14.

[0028] A plurality of limiting grooves 15 are formed in the transverse slide plate 12. The vertical cross-section of the limiting grooves 15 is hemispherical. A contraction groove 16 is formed in the inner wall of the sleeved housing 11 close to the limiting grooves 15. A limiting rod 17 is slidably connected in the contraction groove 16. One end of the limiting rod 17 extends into the sleeved housing 11 and fits with the limiting grooves 15. A spring 18 is provided between the limiting rod 17 and the inner wall of the contraction groove 16. In this way, when the sleeved slide plate 12 slides in the sleeved housing 11, the arc surface of the limiting grooves 15 will squeeze the limiting rod 17, so that the limiting rod 17 moves into the contraction groove 16. At the same time, the spring 18 is stressed and contracts. When the sleeved slide plate 12 moves to a specified position, the limiting rod 17 moves into the limiting grooves 15 under the push of the spring 18, thus completing the preliminary fixation of the transverse slide plate 12. In this way, it is convenient to install the edge guardrail, and there will be no problem of self-movement of the transverse slide plate 12 during the installation process.

[0029] The working principle of the adjustable edge protection railing inside the building provided by the utility model is as follows: When stretching the distance between the two columns 1, the first rotating plate 4, the second rotating plate 5 and the third rotating plate 6 rotate in opposite directions. At the same time, the sliding sleeve 3 displaces downward on the column 1, and the hinge seat 7 displaces downward. At this time, the contact ball 10 is always in contact with the lower surface of the sheathing housing 11 or the transverse sliding plate 12 under the pulling of the tension spring 14. When contracting the distance between the two columns 1, the first rotating plate 4, the second rotating plate 5 and the third rotating plate 6 rotate in the relative direction. At the same time, the sliding sleeve 3 displaces upward on the column 1, and the sheathing housing 11 and the transverse sliding plate 12 will squeeze the contact ball 10, making the contact ball 10 on the side close to the limiting housing 8. At the same time, the tension spring 14 is pulled by the built-in sliding plate 13 and is in a stretched state.
