Description

Technical Field

[0001] This utility model relates to the field of structural technology of elevator cars, specifically a slot-type glass fixing device. Background Technology

[0002] An elevator car is an enclosed space in an elevator system used to carry passengers or goods. Its design must meet the requirements of safety, comfort, and functionality. Modern elevator cars are usually constructed with a metal frame (such as stainless steel or aluminum alloy) combined with materials such as glass and decorative panels. The interior is equipped with lighting, ventilation, control panels, and safety devices (such as emergency communication systems). Depending on the purpose, elevator cars can be divided into passenger elevators, freight elevators, medical elevators, etc., and can be adapted to diverse scenarios through customized designs (such as sightseeing glass elevator cars and barrier-free designs).

[0003] Traditional elevator car glass fixing methods have several technical drawbacks: In terms of space utilization, the use of adhesive strips or Hawking bend fixing methods results in an overly heavy installation structure, and the adhesive strip filling requires additional space. This not only fails to meet the requirements of modern elevator slim designs but also significantly reduces the effective usable space inside the car. In terms of installation and maintenance, traditional adhesive strip fixing methods require waiting for the adhesive to fully cure, leading to low installation efficiency and complex processes. Furthermore, the aging and failure of the adhesive strip material results in high regular replacement and maintenance costs. In terms of structural performance, the traditional Hawking bend process suffers from insufficient precision, easily causing loosening between the glass and the frame, affecting the overall structural strength. Exposed fasteners or adhesive strips also severely impact the aesthetics of the car's viewing surface. In terms of ease of use, existing technologies lack efficient and rapid locking and releasing mechanisms. Glass replacement or repositioning often requires disassembling the entire frame structure, causing significant inconvenience for maintenance operations.

[0004] Therefore, a slot-type glass fixing device is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a slot-type glass fixing device to solve the problems of low space utilization, high installation and maintenance costs, insufficient structural strength and aesthetics, and inconvenient adjustment in the current traditional elevator car glass fixing methods mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a slot-type glass fixing device, comprising a glass body and self-locking components symmetrically arranged on the left and right sides of the glass body, wherein the self-locking components include a fixing frame, a limiting groove is formed inside the fixing frame at one end near the glass body, a rubber pad is provided on one side of the limiting groove, and the other side of the rubber pad is tightly fitted to the side of the glass body.

[0007] Three columns are evenly fitted inside the fixed frame, and the columns are fixedly connected to the bridge box frame.

[0008] A baffle is attached to one side of the fixed frame, and a plurality of assembly holes are evenly opened on the baffle, with a threaded post passing through each assembly hole;

[0009] A spring washer is fitted on the outer side of one end of the threaded column. One side of the spring washer is in contact with the baffle, and the other side is in contact with and connected to a nut. The nut is threadedly connected to the threaded column.

[0010] The threaded column has a through hole inside, and a push rod is movably sleeved in the through hole. Two return springs are symmetrically fixedly connected to both sides of one end of the push rod, and the other end of the return spring is fixedly connected to the inner wall of the threaded column.

[0011] The push rod is symmetrically connected to two stop rods on both sides near the end of the return spring. One end of the stop rod is in contact with the inner wall of the fixed frame, and the other end is rotatably connected to the threaded column through a limiting post. The two ends of the limiting post are fixed to the inner wall of the threaded column.

[0012] Preferably, the cross-section of the limiting groove is U-shaped.

[0013] Preferably, the cross-section of the rubber pad is trapezoidal, and its thickness is one-third of the width of the limiting groove.

[0014] Preferably, the end of the push rod is provided with a 45-degree inclined meshing tooth surface that matches the tooth profile of the stop rod.

[0015] Preferably, the contact end between the stop bar and the inner wall of the fixed frame is provided with anti-slip texture.

[0016] Preferably, the two ends of the limiting post are fixed to the inner wall of the threaded post by welding.

[0017] Preferably, the return spring has a pre-compression amount, so that the stop lever always maintains an outward expansion trend when no external force is applied.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This slot-type glass fixing device, through the innovative design of a U-shaped limiting groove and a mechanical self-locking component, achieves rapid glass installation and removal while also possessing advantages such as space optimization, structural stability, and long-term reliability, significantly improving the overall performance of the elevator car glass fixing system. The specific details are as follows:

[0019] 1. Space optimization

[0020] The composite structure design of U-shaped limiting groove and trapezoidal rubber pad ensures precise glass positioning while significantly reducing the overall thickness of the fixing structure. Combined with built-in self-locking components, it achieves non-protruding installation, effectively meeting the thin design requirements of elevator cars and significantly optimizing the utilization of internal space.

[0021] 2. Installation and maintenance

[0022] The mechanical self-locking mechanism with spring preload replaces the traditional adhesive fixing method. During installation, simply push the glass into the limiting groove for automatic locking, eliminating curing waiting time and greatly improving installation efficiency. At the same time, the push rod-stop linkage mechanism supports one-handed operation for quick unlocking, making glass maintenance and replacement more convenient and efficient.

[0023] 3. Structural reliability

[0024] The three-point column layout combined with pre-compressed return springs makes the glass more evenly stressed, significantly enhancing the overall impact resistance. At the same time, the anti-slip textured bar fits tightly with the inner wall of the frame, forming stable friction, effectively suppressing structural loosening that may be caused by elevator vibration, and ensuring long-term stable and reliable use.

[0030] 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.

[0031] Please see Figure 1-4 The present invention provides a technical solution: a slot-type glass fixing device, including a glass body 1 and self-locking components 2 symmetrically arranged on the left and right sides of the glass body 1. The self-locking components 2 include a fixing frame 201. A limiting groove 202 is opened inside the fixing frame 201 near the glass body 1. A rubber pad 203 is provided on one side of the limiting groove 202. The other side of the rubber pad 203 is tightly fitted to the side of the glass body 1.

[0032] The symmetrically arranged self-locking components 2 ensure that the glass body 1 is subjected to uniform force on both sides, effectively avoiding stress concentration on one side. The elastic deformation of the rubber pad 203 can automatically compensate for minor dimensional deviations during processing and assembly. The tight fit design of the rubber pad 203 can effectively absorb and attenuate high-frequency vibration energy. Through the buffering effect of its elastic contact interface, it can significantly suppress the resonance phenomenon of the glass, thereby significantly improving the overall noise reduction effect.

[0033] Three uprights 204 are evenly fitted inside the fixed frame 201, and the uprights 204 are fixedly connected to the bridge box frame. A baffle 205 is attached to one side of the fixed frame 201. Multiple assembly holes 206 are evenly opened on the baffle 205, and a threaded post 207 is inserted into each assembly hole 206. A spring washer 208 is fitted on the outer side of one end of the threaded post 207. One side of the spring washer 208 is attached to the baffle 205, and the other side is attached to a nut 209. The nut 209 is threadedly connected to the threaded post 207.

[0034] Three evenly distributed columns 204 form a stable triangular support structure, which significantly improves the load-bearing capacity of the overall frame. The rigid connection between the columns 204 and the car frame ensures that the force transmission path is minimized and the glass load is effectively distributed. The evenly distributed multiple mounting holes 206 achieve force balance and avoid local stress concentration. The elastic compensation function of the spring washer 208 can offset the loosening of the connectors during long-term use.

[0035] The threaded column 207 has a through hole 210 inside, and a push rod 211 is movably sleeved in the through hole 210. A return spring 212 is symmetrically fixedly connected to both sides of one end of the push rod 211, and the other end of the return spring 212 is fixedly connected to the inner wall of the threaded column 207. A stop rod 213 is symmetrically engaged with both sides of the push rod 211 near the end of the return spring 212. One end of the stop rod 213 contacts and cooperates with the inner wall of the fixed frame 201, and the other end is rotatably connected to the threaded column 207 through a limiting post 214. The two ends of the limiting post 214 are fixed to the inner wall of the threaded column 207.

[0036] The preload of the return spring 212 ensures that the stop lever 213 always maintains reliable locking contact pressure; the meshing connection design between the push rod 211 and the stop lever 213 allows for single-handed operation to switch the locking state; the symmetrically arranged stop levers 213 form a bidirectional locking force, effectively preventing glass displacement under vibration; the rotating connection structure of the limit post 214 ensures precise control of the movement trajectory of the stop lever 213;

[0037] The cross-section of the limiting groove 202 is U-shaped;

[0038] The U-shaped opening structure provides a natural guiding channel for glass insertion, ensuring centering during installation; the three-sided surround constraint effectively restricts the glass's degrees of freedom in all directions;

[0039] The cross-section of the rubber pad 203 is trapezoidal, and its thickness is one-third of the width of the limiting groove 202;

[0040] The trapezoidal structure's sloping design creates a progressive compression contact, ensuring a uniform distribution of sealing pressure; the cross-sectional shape, wider at the top and narrower at the bottom, achieves a double sealing effect, effectively preventing water vapor penetration; the trapezoidal structure provides a self-centering function, facilitating accurate glass positioning and installation; the progressive compression characteristics avoid sudden stress changes during installation.

[0041] The end of the push rod 211 is provided with a 45-degree inclined meshing tooth surface, which matches the tooth profile of the stop rod 213; the contact end of the stop rod 213 with the inner wall of the fixed frame 201 is provided with anti-slip texture; the two ends of the limiting post 214 are fixed to the inner wall of the threaded post 207 by welding; the return spring 212 has a pre-compression amount, so that the stop rod 213 always maintains the tendency to expand outwards when no external force is applied;

[0042] The 45-degree inclined meshing tooth surface design not only ensures smooth force transmission between the push rod 211 and the stop lever 213, but also significantly improves transmission efficiency and operational smoothness through precise tooth profile matching. The anti-slip texture on the contact end of the stop lever 213 effectively increases the coefficient of friction, ensuring that the locking force remains reliable and stable under various working conditions. The limit post 214 is fixed by welding, providing permanent structural support and completely eliminating the loosening risks that may occur with traditional threaded connections. The pre-compressed return spring 212 continuously provides a constant initial expansion force, ensuring that the stop lever 213 automatically remains in the locked state when no external force is applied, greatly improving the safety performance of the system. At the same time, the optimized angle design and systematic detail processing make the overall operation more effortless and convenient. These carefully designed structural features work together to construct a high-performance self-locking mechanism system that is highly efficient in transmission, reliable in anti-slip, structurally stable, automatically reset, and easy to operate.

[0043] Working principle: Before using this type of slot-type glass fixing device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 4 As shown:

[0044] During installation, the glass body 1 is pushed in along the U-shaped limiting grooves 202 on the left and right sides. The side of the glass body 1 is tightly fitted with the trapezoidal rubber pad 203. The elastic deformation of the rubber pad 203 provides initial pre-tightening force to ensure the initial positioning of the glass. The trapezoidal structure of the rubber pad 203 not only provides sealing and buffering, but also absorbs the vibration energy of the elevator during operation and reduces noise.

[0045] After the glass body 1 is fully embedded in the limiting groove, the fixing frame 201 is wrapped around the corresponding column 204 on the elevator car. The stop bar 213 expands outward under the pre-compression of the return spring 212. The anti-slip texture at its end is in close contact with the inner wall of the fixing frame 201, forming a stable frictional locking force to prevent the baffle 205 from loosening or slipping, which would cause the fixing frame 201 to be unstable in installation. At this time, the push rod 211 is kept in an outward pushing state under the action of the return spring 212. The 45° meshing tooth surface at its end meshes with the stop bar 213, further enhancing the locking stability and ensuring that the glass body 1 will not shift due to vibration during elevator operation.

[0046] During disassembly, simply press the push rod 211 to move it inward. The meshing tooth surface of the push rod 211 drives the stop rod 213 to rotate around the limiting post 214, causing the end of the stop rod 213 to disengage from the inner wall of the fixed frame 201, releasing the locking state and realizing the quick disassembly of the glass body 1 from the fixed frame 201.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
