[0002] The safety of construction projects has always been the red line of construction management, and it is particularly valued by everyone from the country to individuals. Elevator shaft edge protection, as an indispensable safety measure for every project, is a key link in eliminating safety hazards and occupies an important position in safety management.

[0003] At present, the edge protection of vertical elevator openings at construction sites is mostly still customized with standardized protective meshes and grilles. The meshes or grilles are fixed with ear plates at the four corners of the protective door with expansion screws. This protection method is relatively rigid and has poor adjustability. Because the sizes of vertical elevator openings often vary for different projects, buildings, and locations, the size of the protective mesh needs to be customized according to different on-site conditions, which makes the construction of edge protection of vertical elevator openings cumbersome. Utility Model Content

[0004] In view of this, the utility model provides an elevator safety protection door, which aims to solve the defect of the elevator safety protection door in the prior art that is inconvenient to operate.

[0005] The utility model provides an elevator safety protection door, comprising a protection frame, an adjustment beam, a sliding ring, and a fixed hook; a protection block is installed on the protection frame; the adjustment beam is horizontally connected to the protection frame, and the adjustment beam is exposed on the front and back sides of the protection frame; the sliding ring is slidably arranged on the adjustment beam, and the sliding ring can rotate on the adjustment beam, and a locking piece is connected to the sliding ring, and the locking piece cooperates with the adjustment beam to fix the sliding ring on the adjustment beam; the fixed hook is fixedly connected to the sliding ring, and the fixing hook has an extension portion and a hook portion connected to the extended end of the extension portion, the extension portion is used to extend toward the inside of the elevator door opening, and the hook portion extends toward one side and is used to be clamped on the back side of the masonry on the side of the elevator door opening.

[0006] By setting up a protective frame and protective stops, a stable protective structure is provided for the elevator door opening, preventing people or objects from falling accidentally; by adjusting the horizontal connection of the protective frame with a beam, the strength and stability of the overall structure are increased, so that it can withstand external force impact; by exposing the adjusting beam on the front and back sides of the protective frame, and arranging a slidable sliding ring with a fixed hook on the adjusting beam, and being able to adjust the position according to the actual needs of the elevator protective door, so that it can adapt to elevator door openings of different sizes, the versatility and ease of operation of the protective door are improved; the sliding ring is fixed by a locking piece to ensure that the sliding ring does not move at will during the use of the elevator door, thereby ensuring the reliability of protection; the fixed hook is fixedly connected to the sliding ring, and the extension of the fixed hook extends toward the inside of the elevator door opening, and the hook part is clamped on the back of the masonry, ensuring that the protective door can be firmly fixed at the elevator door opening; through the mutual cooperation of the various components of the protective door, a complete protection system is formed, which effectively prevents people from accidentally entering the elevator shaft and reduces the probability of safety accidents.

[0007] Optionally, the present invention provides an elevator safety protection door, wherein the adjustment beam is arranged in an area of ​​the protection frame where the protection block is not arranged.

[0008] By installing an adjustment beam in an area where no protective baffle is provided, it is easier for staff to adjust the position of the sliding ring and the fixed hook, ensuring that the hook portion of the fixed hook can be more firmly connected to the back of the masonry on the side of the elevator door opening, so that the fixed hook and the sliding ring have more space for adjustment, thereby ensuring the protective effect of the protective door.

[0009] Optionally, the utility model provides an elevator safety protection door, wherein there is a gap between the protection block and the upper side of the protection frame, and the adjustment beam is arranged in the gap.

[0010] By setting the adjustment beam in the gap between the protective block and the protective frame, a stable installation foundation is provided for the sliding ring without affecting the normal protective function of the protective block. Since the adjustment beam is in a relatively independent space, the sliding ring will not be interfered with by the protective block when sliding and rotating horizontally on it, and can adjust the position more smoothly, making it convenient to adjust the position of the fixed hook according to the actual situation of the elevator door opening.

[0011] Optionally, the utility model provides an elevator safety protection door, wherein the locking member is connected to the sliding ring through a thread, and the locking member passes through the sliding ring and abuts against the adjusting beam to fix the sliding ring on the adjusting beam.

[0012] The threaded connection enables highly precise adjustment. By rotating the locking element, the degree of its rotation within the sliding ring can be precisely controlled, allowing for fine adjustment of the sliding ring's position on the adjustment beam. The threaded connection also provides a stable and reliable fixation. By abutting the locking element against the adjustment beam, it can withstand significant external forces, preventing the sliding ring from shifting even during long-term use, thereby ensuring the stability and safety of the protective door structure.

[0013] Optionally, the utility model provides an elevator safety protection door, wherein a through hole is provided on the sliding ring, and a nut for threaded connection with the locking member is connected to the through hole.

[0014] The fixing of the sliding ring is more accurate by threading the nut and the locking piece at the through hole. Meanwhile, the sliding ring can be firmly fixed by tightening the locking piece and the nut to prevent it from being loosened and shifted due to external force.

[0015] Optionally, the present invention provides an elevator safety protection door, wherein the protection barrier is a mesh structure.

[0016] By adopting a mesh structure for the protective barrier, the grid formed by it can prevent the passage of human bodies and small objects. At the same time, the mesh structure has a certain degree of transparency and will not completely block the line of sight. People around the elevator shaft can see part of the situation inside the elevator shaft through the mesh, which is very helpful for maintenance personnel to check the operating status of the elevator or construction personnel to determine whether there are potential dangers in the elevator shaft.

[0017] Optionally, the present invention provides an elevator safety protection door, wherein the protection frame is connected to a support beam in an area for setting the protection block.

[0018] By connecting a support beam to the guardrail, the guardrail prevents people or objects from accidentally passing through the elevator door opening while providing additional support and enhancing its stability. Furthermore, since elevator safety doors are constantly subjected to various forces during daily use, the support beam reduces vibration and deformation of the guardrail, thereby extending the service life of the door.

[0019] Optionally, the utility model provides an elevator safety protection door, wherein the sliding ring and the fixing hook have two symmetrically arranged groups.

[0020] Two symmetrical sets of sliding rings and fixing hooks stabilize the protective door in the elevator door opening. When subjected to external forces, the symmetrical fixing hooks evenly distribute the applied force. Furthermore, the two symmetrical fixing hooks better grip the back of the masonry on the side of the elevator door opening. If one fixing hook becomes loose or damaged, the other symmetrical fixing hook can still provide a certain degree of fixation, providing maintenance personnel with ample time to repair or replace the damaged component, thereby enhancing the protective reliability of the protective door and reducing the risk of safety accidents.

[0021] Optionally, the present invention provides an elevator safety protection door, wherein the upper side and / or the lower side of the protection frame is a baffle structure.

[0022] By adding baffles to the top, bottom, or both sides of the protective frame, the overall structure of the protective door is made more stable and the frame's bending resistance is increased. When the protective door is subjected to external forces, the baffles can disperse these forces, reducing the risk of deformation of the protective frame, thereby extending the service life of the protective door and ensuring its stable protection in various environments.

[0023] Optionally, the utility model provides an elevator safety protection door, wherein the extension portion is perpendicular to the adjustment beam, and the hook portion is perpendicular to the extension portion.

[0024] By fixing the extension perpendicularly to the adjustable crossbeam, the elevator safety door can more effectively transmit external forces from the protective frame through the adjustable crossbeam to the extension when subjected to external forces. Furthermore, the hook's perpendicular position to the extension allows it to better resist pulling forces from various directions when attached to the back of the masonry on the side of the elevator door opening. By virtue of its perpendicularity to the extension, the hook transfers external forces through the extension to the adjustable crossbeam and protective frame, ensuring the overall stability of the safety door and preventing it from loosening or shifting.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0034] like Figure 1 and Figure 2 As shown, the present embodiment provides an elevator safety protection door, which includes a protection frame 1, an adjustment beam 3, a sliding ring 4 and a fixed hook 6. A protection block 2 is mounted on the protection frame 1, and the adjustment beam 3 is horizontally connected to the protection frame 1 and is exposed on both the front and back sides of the protection frame 1. The sliding ring 4 is slidably arranged on the adjustment beam 3 and can also rotate on the adjustment beam 3. A locking member 5 is connected to the sliding ring 4, and the locking member 5 cooperates with the adjustment beam 3 to fix the sliding ring 4 on the adjustment beam 3. The fixed hook 6 is fixedly connected to the sliding ring 4, and the fixed hook 6 has an extension portion 7 and a hook portion 8. The extension portion 7 is connected to the extended end of the hook portion 8. The extension portion 7 is used to extend toward the inside of the elevator door opening, and the hook portion 8 extends to one side and can be snapped onto the back of the masonry on the side of the elevator door opening. By installing the adjustment beam 3 in the area where the protective baffle 2 is not set, it is easier for the staff to adjust the position of the sliding ring 4 and the fixed hook 6, ensuring that the hooking part 8 of the fixed hook 6 is more firmly clamped on the back of the masonry on the side of the elevator door opening, providing a larger adjustment space for the fixed hook 6 and the sliding ring 4, thereby ensuring the protective effect and stability of the protective door.

[0035] like Figure 1 and Figure 2 As shown, this is a specific implementation of an elevator safety protection door provided by this embodiment. The adjustment beam 3 is set in an area on the protection frame 1 where the protection block 2 is not set, that is, there is a protection block 2 in the area surrounded by the protection frame 1, and the adjustment beam 3 is installed in the blank area of ​​the area where the protection block 2 is not set. The reason for this arrangement is that it can provide greater convenience for the staff, making it easier to adjust the position of the sliding ring 4 and the fixed hook 6. In this way, it can ensure that the hook portion 8 of the fixed hook 6 can be more firmly connected to the back of the masonry on the side of the elevator door opening. At the same time, it also allows the fixed hook 6 and the sliding ring 4 to have more sufficient space for position adjustment, thereby effectively ensuring the protective effect of the protection door. Such a design fully takes into account various needs in actual operation. On the basis of ensuring the functionality of the protection door, its adjustability and applicability are improved, providing more reliable protection for the safety protection of the elevator door opening.

[0036] like Figure 1 and Figure 2 The figure shows a specific embodiment of an elevator safety door provided by this embodiment. A gap exists between the protective block 2 and the upper edge of the protective frame 1, and the adjustment beam 3 is positioned within this gap. In this embodiment, the gap exists between the protective block 2 and the upper edge of the protective frame 1, and the adjustment beam 3 is positioned precisely within this gap. This arrangement provides an extremely stable mounting base for the sliding ring 4 without compromising the protective function of the protective block 2. This is because the adjustment beam 3 is located in a relatively independent space. When the sliding ring 4 slides and rotates on it, it is completely uninterrupted by the protective block 2, allowing for smoother and more unobstructed position adjustment. This allows the position of the fixing hook 6 to be conveniently adjusted according to the actual conditions of the elevator door opening. This design cleverly balances protective functionality with ease of adjustment, making the entire device more flexible and efficient in practical applications and providing an optimized solution for the installation and adjustment of elevator door opening-related components.

[0037] like Figure 3As shown, a specific implementation method of an elevator safety protection door provided by this embodiment is provided, in which the locking member 5 and the sliding ring 4 are connected by threads. Specifically, the locking member 5 passes through the sliding ring 4 and abuts against the adjusting beam 3, thereby fixing the sliding ring 4 on the adjusting beam 3. This threaded connection method has significant advantages. On the one hand, it can achieve high-precision adjustment. By rotating the locking member 5, the degree of its screwing in or out in the sliding ring 4 can be controlled extremely accurately, and then the position of the sliding ring 4 on the adjusting beam 3 can be finely adjusted. On the other hand, the threaded connection has a stable and reliable fixing effect. When the locking member 5 abuts the adjusting beam 3, it can withstand a large external force, and even in the long-term use process, it can effectively prevent the sliding ring 4 from being displaced, thereby effectively ensuring the stability and safety of the protection door structure.

[0038] Of course, the above description is not restrictive. In some replaceable embodiments, the locking member 5 and the sliding ring 4 are threadedly connected and can be replaced by a latch structure. A latch hole is provided at the position of the through hole 9 of the sliding ring 4, and the corresponding locking member 5 is changed to a latch. The latch can be a metal rod with an anti-slip head at one end. When locking is required, the latch is inserted into the latch hole, and fixation is achieved through the mechanical blocking effect of the latch. This structure is simple and reliable, with low cost, and the installation and disassembly of the latch is relatively easy, which is convenient for daily maintenance and inspection.

[0039] like Figure 3 The figure shows a specific embodiment of an elevator safety door provided by this embodiment. A through-hole 9 is provided on the sliding ring 4, to which a nut 10 for threaded connection with the locking member 5 is connected. This design, through the through-hole 9, uses the nut 10 to threadably connect with the locking member 5, enabling more precise securing of the sliding ring 4. Furthermore, by tightening the locking member 5 and the nut 10, the sliding ring 4 is securely fixed, effectively preventing it from loosening and shifting due to external forces, further enhancing the stability and reliability of the elevator safety door during use.

[0040] Of course, the above description is not restrictive. In some alternative embodiments, the threaded locking member 5 is no longer used. Instead, a latch structure is designed, and the through hole 9 of the sliding ring 4 is replaced with a corresponding pin hole. The locking member 5 uses a latch. When locking is required, the latch is inserted into the latch hole, and the locking function is achieved through the mechanical blocking effect of the latch.

[0041] like Figure 1As shown, a specific implementation of an elevator safety protection door provided by this embodiment, wherein the protective barrier 2 is a mesh structure. By adopting this mesh structure as the protective barrier 2, the grid formed has the function of blocking the passage of human bodies and small objects. At the same time, the mesh structure also has a certain degree of transparency and will not completely block the line of sight. In this way, people around the elevator shaft can observe part of the conditions inside the elevator shaft through the mesh. This feature is extremely helpful for maintenance personnel to check the operating status of the elevator, or for construction personnel to determine whether there are potential dangers in the elevator shaft. It provides convenience for relevant personnel in the work process, ensuring safety while taking into account a certain degree of visibility, so that it can better meet actual needs in terms of elevator safety protection.

[0042] like Figure 1 The figure shows a specific embodiment of an elevator safety door provided by this embodiment. A support beam 11 is connected to the protective frame 1 in the area where the protective barrier 2 is located. This design effectively prevents people or objects from accidentally passing through the elevator door opening while also providing additional support for the protective barrier 2, thereby enhancing its stability. Because elevator safety doors are constantly subjected to various forces during daily use, the presence of the support beam 11 reduces the shaking and deformation of the protective barrier 2, thereby extending the service life of the door.

[0043] like Figure 1 As shown, a specific implementation method of an elevator safety protection door provided by this embodiment is provided, in which the sliding ring 4 and the fixing hook 6 have two symmetrically arranged groups. Through these two groups of symmetrically arranged sliding rings 4 and fixing hooks 6, the stability of the protection door at the elevator door opening can be significantly improved. When the protection door is subjected to external force, the fixing hooks 6 symmetrical on both sides can evenly share the force, avoiding the situation where the protection door is tilted or damaged due to uneven force. At the same time, the two groups of symmetrical fixing hooks 6 have a better effect when they are stuck on the back of the masonry on the side of the elevator door opening. If one of the fixing hooks 6 becomes loose or damaged, the other symmetrical fixing hook 6 can still play a certain fixing role, providing maintenance personnel with sufficient time to repair or replace the damaged parts, thereby greatly enhancing the protection reliability of the protection door and effectively reducing the risk of safety accidents.

[0044] like Figure 1As shown, a specific implementation method of an elevator safety protection door provided by this embodiment, the upper and / or lower sides of its protective frame 1 are presented as a baffle structure 12. Through such a design, when the protective door is in an actual application scenario, the baffle structure 12 provided on the upper side, lower side, or both upper and lower sides of the protective frame 1 can make the protective door more stable in terms of the overall structure, and significantly enhance the bending resistance of the protective frame 1. Specifically, when the protective door is subjected to various external forces, the baffle can effectively disperse these external forces, greatly reducing the risk of deformation of the protective frame 1. In this way, not only can the service life of the protective door be extended, but it can also ensure that it can stably play a protective role in various complex environments, providing reliable protection for the safe operation of the elevator.

[0045] like Figure 2 and Figure 4 As shown, a specific implementation of an elevator safety protection door provided by this embodiment is shown, in which the extension portion 7 is perpendicular to the adjustment beam 3, and the hook portion 8 is perpendicular to the extension portion 7. By fixing the extension portion 7 perpendicularly to the adjustment beam 3, when the elevator safety protection door is subjected to external force, the external force can be more effectively transmitted from the protection frame 1 to the extension portion 7 via the adjustment beam 3. At the same time, the structure in which the hook portion 8 is perpendicular to the extension portion 7 enables the hook portion 8 to better resist pulling forces from different directions when it is clamped on the back of the masonry on the side of the elevator door opening. With the structure in which the hook portion 8 is perpendicular to the extension portion 7, external force can be transmitted to the adjustment beam 3 and the protection frame 1 through the extension portion 7, thereby ensuring the overall stability of the protection door and effectively preventing the protection door from loosening or shifting.

[0046] Working Principle: When using the elevator safety protection door provided by this solution, the maximum width of the elevator opening at the project site can be calculated as the width dimension of the standardized protection door. After the standardized elevator protection door arrives on site, the adjustment beam 3, sliding ring 4 and fixed hook 6 are manufactured and installed. By sliding the sliding ring 4 at both ends of the beam 3 left and right and adjusting the angle of the extension part 7 and hook part 8 of the fixed hook 6, the elevator door fixed hook 6 is fixed and stuck to the back of the masonry of the door opening and locked with the locking part 5, thereby achieving the purpose of fixing the elevator protection door. If the elevator protection door needs to be temporarily removed at the construction site, it is only necessary to adjust the sliding ring 4 again to slide the fixed hook 6 out from the back of the elevator opening to remove the protection door.

[0047] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope of the present invention.
