Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, and in particular to a safety protection installation buckle for elevator door openings. Background Technology

[0002] Elevator doorways are the elevator entrances and exits reserved on each floor during building construction. Before the elevator is officially installed, in order to prevent safety accidents such as people falling or materials falling, protective railings need to be installed at the elevator doorways to isolate and intercept them, forming a reliable safety barrier to ensure the safety of operations during construction.

[0003] During the main structure construction phase, standardized fences are often used to enclose the facades of elevator doors and floors for safety protection. These fences are usually fixed to the wall using nails, expansion bolts, and saddle clips. This installation method inevitably causes direct damage to the wall surface. Furthermore, since this protective facility needs to be retained until the formal elevator installation, the removal of the fences during subsequent plastering and other finishing work often causes secondary damage to the wall surface and the protective system itself, ultimately leading to additional rework and repair work. This not only prolongs the construction period but also causes unnecessary waste of manpower, material resources, and financial resources, and may also affect the overall quality of the wall decoration. Summary of the Invention

[0004] This utility model relates to a safety protection installation buckle for elevator door openings. It features a fixed buckle and a movable buckle. The movable buckle can adjust its distance from the fixed buckle to fit the thickness of the elevator door opening wall. After adjustment, tightening the nuts secures the fixed and movable buckles, clamping them onto the walls on both sides of the elevator door opening. The guardrail is then hung on the buckle, completing the elevator shaft protection system. This eliminates the need for drilling holes in the wall during installation, preventing irreversible damage. The system can also be easily disassembled for subsequent processes such as plastering, minimizing time spent on disassembly. This utility model is simple to install, fast to construct, and effectively improves the efficiency of the protection system's construction. Furthermore, it is easy to disassemble, reusable, and eliminates the need for repeated material purchases, saving costs and preventing irreversible damage to the building structure, reducing rework and further conserving manpower and resources.

[0005] In a first aspect, this utility model provides a safety protection installation buckle for elevator door openings, specifically comprising: a fixed buckle, wherein two hanging buckles are symmetrically fixedly installed at the upper and lower ends of the front side of the fixed buckle; a clamping screw is fixedly installed on the inner side of the fixed buckle; a movable buckle is slidably installed on the clamping screw; an installation end is fixedly installed at the rear end of the clamping screw; a thread is provided at the rear end of the clamping screw, and a clamping nut is installed on the clamping screw through the thread; a connecting ring is rotatably installed on the rear side of the clamping nut; one end of a sealing sleeve A is embedded in the front side of the installation end, and the other end of the sealing sleeve A is embedded in the rear side of the connecting ring; one end of a sealing sleeve B is embedded in the front side of the movable buckle, and the other end of the sealing sleeve B is embedded in the rear side of the fixed buckle.

[0006] Furthermore, the fixing buckle has an L-shaped structure; the hanging buckle has an L-shaped structure.

[0007] Furthermore, the two mounting buckles are bent in opposite directions; the movable buckle has an L-shaped structure.

[0008] Furthermore, the bending direction of the movable buckle is opposite to the bending direction of the fixed buckle; the clamping nut is located behind the movable buckle.

[0009] Furthermore, the sealing sleeve B and sealing sleeve A are telescopic sleeve structures; a protective railing is mounted on the hanging buckle.

[0010] Furthermore, the sealing sleeve B surrounds the smooth section of the clamping screw; the sealing sleeve A surrounds the threaded section of the clamping screw.

[0011] Furthermore, when the sealing sleeve B contracts, the sealing sleeve A extends; when the sealing sleeve A contracts, the sealing sleeve B extends.

[0012] This utility model provides a safety protection installation buckle for elevator door openings, which has the following beneficial effects:

[0013] (I) This utility model is not only easy to install and efficient to construct, which can significantly improve the construction efficiency of the protection system, but also easy to disassemble and reuse. It does not require repeated purchase of materials, thus saving costs and completely avoiding permanent damage to the building structure, reducing rework and repair, and further saving manpower and financial resources.

[0014] (II) By setting fixed and movable buckles, the movable buckle can flexibly adjust the distance between itself and the fixed buckle to adapt to the thickness of the walls on both sides of the elevator door opening. After adjustment, the two can be precisely positioned by tightening the clamping nuts, so that the installation buckles are firmly clamped on both sides of the wall. Then, the guardrail is hung on the hanging buckle, and the elevator shaft protection system can be quickly built. The whole process does not require drilling holes in the wall, which fundamentally avoids irreversible damage to the wall. Moreover, the protection system can be easily disassembled when plastering and other processes are carried out, which greatly shortens the disassembly time and reduces the impact on the construction progress.

[0015] (III) Through the cooperation of sealing sleeve A and sealing sleeve B, sealing sleeve A forms a sealed wrap around the threaded section of the clamping screw, while sealing sleeve B seals and protects its smooth section. This double sealing structure can effectively isolate moisture and prevent the clamping screw from rusting due to rainwater erosion when the elevator door opening is located at the edge of the building, ensuring smooth adjustment and use. At the same time, the sealing sleeve adopts a telescopic design, which will not hinder the adjustment of the clamping nut and the movable buckle, taking into account both protection and practicality.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1 to 5 Example 1:

[0028] This utility model proposes a safety protection installation buckle for elevator door openings, comprising: a fixed buckle 1, with two hanging buckles 2 symmetrically fixedly installed at the upper and lower ends of the front side of the fixed buckle 1; a clamping screw 3 fixedly installed on the inner side of the fixed buckle 1; a movable buckle 4 slidingly installed on the clamping screw 3; an installation end 5 fixedly installed at the rear end of the clamping screw 3; a thread is provided at the rear end of the clamping screw 3, and a clamping nut 6 is installed on the clamping screw 3 through the thread. The inner side of the fixed buckle 1 is attached to the front wall of one side of the elevator door opening, and then the clamping nut 6 is rotated using a tool, causing the clamping nut 6 to move forward along the threaded section of the clamping screw 3, so that the clamping nut 6 pushes the movable buckle 4 by moving forward, so that the inner side of the movable buckle 4 is attached to the rear wall of one side of the door opening, so that the movable buckle 4 and the fixed buckle 1 cooperate to clamp and fix the installation buckle on the elevator door opening, and then another set of the installation buckle... The buckles are clamped and fixed to the wall on the other side of the elevator door opening in the same way, so that the two mounting buckles are symmetrically clamped on the left and right sides of the elevator door opening. Finally, the guardrail 10 is hung on the hanging buckle 2 of the two mounting buckles to block the elevator door opening. A connecting ring 7 is rotatably installed on the rear side of the clamping nut 6. One end of the sealing sleeve A8 is embedded in the front side of the mounting end 5, and the other end of the sealing sleeve A8 is embedded in the rear side of the connecting ring 7. One end of the sealing sleeve B9 is embedded in the front side of the movable buckle 4, and the other end of the sealing sleeve B9 is embedded in the rear side of the fixed buckle 1. This utility model is simple to install, fast to construct, and can effectively improve the construction efficiency of the protection system. Moreover, this utility model is easy to disassemble, can be reused, and does not require multiple purchases of materials, saving costs while not causing irreversible damage to the building structure, reducing rework problems, and further saving manpower and financial resources.

[0029] In Example 2, based on Example 1, the fixed buckle 1 has an L-shaped structure; the hanging buckle 2 has an L-shaped structure; the bending directions of the two hanging buckles 2 are opposite; the movable buckle 4 has an L-shaped structure; the bending direction of the movable buckle 4 is opposite to the bending direction of the fixed buckle 1; the clamping nut 6 is located behind the movable buckle 4. By setting the fixed buckle 1 and the movable buckle 4, the movable buckle 4 can adjust its distance from the fixed buckle 1, so that the distance between the fixed buckle 1 and the movable buckle 4 can be adapted to the thickness of the elevator door opening wall. After adjustment, the fixed buckle 1 and the movable buckle 4 can be positioned by clamping the buckle 6, so that the installation buckle is clamped on the walls on both sides of the elevator door opening. Then, the guardrail 10 is hung on the hanging buckle 2 to realize the construction of the elevator shaft protection system. In this way, the protection system does not need to be drilled in the wall during construction, and will not cause irreversible damage to the wall. Moreover, the protection system can be easily disassembled when performing subsequent processes such as plastering, without spending too much time on disassembling the protection system.

[0030] In Example 3, based on Example 2, sealing sleeves B9 and A8 are telescopic sleeve structures; a protective railing 10 is hung on the mounting buckle 2; sealing sleeve B9 surrounds the smooth section of the clamping screw 3; sealing sleeve A8 surrounds the threaded section of the clamping screw 3; when sealing sleeve B9 contracts, sealing sleeve A8 extends; when sealing sleeve A8 contracts, sealing sleeve B9 extends. With sealing sleeves A8 and B9, sealing sleeve A8 seals and surrounds the threaded section of the clamping screw 3, and sealing sleeve B9 seals and surrounds the smooth section of the clamping screw 3. Thus, the two sealing sleeve structures protect the clamping screw 3, which plays an adjusting role, preventing the elevator door opening from being located at the edge of the building during construction and causing the clamping screw 3 to come into contact with water during rainy weather, resulting in rust and inconvenience for subsequent use. Furthermore, the sealing sleeve structure is telescopic, so its presence does not affect the adjustment of the clamping nut 6 and the movable buckle 4.

[0031] Working principle: When in use, first attach the inner side of the fixing buckle 1 to the front wall of one side of the elevator doorway. Then, use a tool to rotate the clamping nut 6, causing it to move forward along the threaded section of the clamping screw 3. During the forward movement of the clamping nut 6, it will push the movable buckle 4 until the inner side of the movable buckle 4 is tightly attached to the rear wall of the same side of the doorway. At this time, the fixing buckle 1 and the movable buckle 4 cooperate with each other to firmly clamp and fix the installation buckle on the wall of that side. In the same way, install another set of buckles symmetrically on the other side of the elevator doorway so that the two sets of installation buckles are symmetrically distributed from left to right. Finally, hang the guardrail 10 on the hanging buckle 2 of the two installation buckles to complete the interception and protection of the elevator doorway by the guardrail 10. The operation is convenient and efficient.
