Description

Technical Field

[0001] This utility model relates to the technical field of escalator glass support frames, and in particular to an explosion-proof support device for escalator glass. Background Technology

[0002] As a crucial component of modern escalators, the stability and safety of escalator glass installation directly impact the overall performance and lifespan of the escalator. Traditional escalator glass support frames often employ steel structures, using rigid clamping to secure the glass. However, this structure is prone to uneven stress distribution during installation, leading to localized stress concentration in the glass and potentially causing it to shatter. Furthermore, traditional support frames have limited adjustability, making it difficult to accommodate glass of varying thicknesses or sizes, and lack automatic clamping and buffering mechanisms, resulting in low installation efficiency and cumbersome operation.

[0003] While some improvements have been made in the existing technology, such as using elastic clamping elements or adjusting screws to enhance the clamping effect, the following problems still exist: First, the clamping force is not adjusted evenly enough, which can easily cause local pressure on the glass; second, there is a lack of automatic opening and closing function, which requires manual adjustment during installation, increasing the complexity of operation; and third, the structural design is relatively simple and cannot effectively absorb the stress generated by the glass due to vibration or temperature changes, which can easily lead to loosening or failure after long-term use.

[0004] Therefore, there is an urgent need for an escalator glass explosion-proof support device that is structurally sound, easy to operate, and can effectively prevent uneven stress on the glass. Summary of the Invention

[0005] The main objective of this invention is to overcome the shortcomings of existing technologies and provide an explosion-proof support device for escalator glass. It not only solves the problems of uneven force distribution and complex operation of traditional support frames, but also improves safety, stability, and installation efficiency through innovative mechanical linkage design, making it suitable for fixing various types of escalator glass.

[0006] The technical solution adopted by this utility model to achieve its technical objective is as follows: an escalator glass explosion-proof support device, including a support body, wherein the support body is provided with an opening. The support body is the main structure of the device, and the opening is located above the support body to accommodate other components; the support body provides a foundation for supporting and fixing other components, and the opening provides installation space for clamping components and other linkage components.

[0007] The opening is equipped with a clamping component, which is a U-shaped elastic plastic plate. One side of the clamping component is fixed to the inner wall of the opening, and the other side is connected to a pad. One side of the clamping component is fixed to the inner wall of the opening, and the other side is connected to the rocker plate through the pad. The U-shaped elastic plastic plate design of the clamping component allows it to form an adjustable clamping space for holding the escalator glass. The pad serves as an intermediate connector, transmitting the elastic deformation of the clamping component to the rocker plate.

[0008] The pad is connected to the rocker arm, which has a bent structure. Its vertical section is equipped with an adjusting screw, which is threaded onto the support body and abuts against the rocker arm. The pad is fixedly connected to the rocker arm, and the adjusting screw is threaded onto the support body and abuts against the vertical section of the rocker arm. The bent structure of the rocker arm allows it to deflect around a pivot point. The adjusting screw, by abutting against the vertical section of the rocker arm, allows for fine-tuning of the clamping force of the clamping components.

[0009] The horizontal section of the rocker is connected to a guide plate. The upper end of the guide plate contacts the bottom of the clamping component, and a spring is fitted at the lower end, which is supported by the support body. The guide plate, under the action of the spring, pushes the clamping component upwards, automatically opening the clamping space. When the escalator glass is placed, the guide plate is pressed down, the spring is compressed, and the clamping component automatically clamps the glass.

[0010] Preferably, the pad has a barbed structure, with its vertical surface fixed to the clamping member and its inclined surface fixed to the rocker. The vertical surface of the pad is fixed to the clamping member, and the inclined surface is fixed to the rocker; the barbed structure enhances the connection stability between the pad, the clamping member, and the rocker, ensuring effective force transmission.

[0011] Preferably, one end of the adjusting screw has a semi-circular head structure, which abuts against the vertical plate portion of the rocker, while the other end is the operating end. The semi-circular head of the adjusting screw abuts against the vertical plate portion of the rocker, while the other end is the operating end, facilitating manual adjustment; the semi-circular head structure reduces friction, making adjustment smoother; the operating end allows the user to adjust the clamping force manually using tools.

[0012] Preferably, the support body is provided with at least two staggered adjusting screws. The at least two adjusting screws are staggered on the support body and both abut against the vertical plate portion of the rocker; multiple adjusting screws provide more uniform clamping force adjustment and avoid clamping failure caused by uneven force at a single point.

[0013] Preferably, a movable gap is provided between the lower end of the vertical plate portion of the rocker and the support body. This movable gap provides space for the rocker to deflect, ensuring its flexible movement and preventing it from jamming.

[0014] Preferably, the bent portion of the rocker is rotatably connected to the mounting groove of the bracket body via a rotating shaft. The bent portion of the rocker is connected to the mounting groove via a rotating shaft, and the mounting groove is located within the bracket body; the rotating shaft serves as the fulcrum of the rocker, allowing it to deflect around its axis, thereby achieving automatic opening and closing of the clamping components.

[0015] Preferably, the upper end of the guide plate is a flat plate structure that is slidably connected to the support body; the lower end is a column structure with a spring sleeved on it. The flat plate structure at the upper end of the guide plate is slidably connected to the support body, and the column structure at the lower end is sleeved with a spring; the flat plate structure ensures stable contact between the guide plate and the bottom of the clamping component, and the column structure provides installation space for the spring, achieving elastic support.

[0016] Preferably, a sealing block is provided at the opening of the mounting groove, one end of the spring abuts against the horizontal plate portion of the rocker, and the other end abuts against the sealing block. The sealing block closes the opening of the mounting groove, and both ends of the spring abut against the horizontal plate portion of the rocker and the sealing block respectively; the sealing block fixes the position of the spring, ensuring that the spring can stably provide elastic force to support the movement of the rocker.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This escalator glass explosion-proof support device features automatic clamping and buffering functions. Through the coordinated design of a U-shaped elastic plastic plate (clamping element), springs, and rocker, the device automatically adapts to the insertion of the glass, achieving dynamic adjustment of the clamping force. The elastic support of the springs not only simplifies the installation process but also effectively absorbs vibration or impact, reducing the risk of glass breakage.

[0019] This escalator glass explosion-proof support device enables uniform force distribution and precise adjustment: multiple staggered adjusting screws abut against the rocker plate allow for multi-point fine-tuning of the clamping force, ensuring uniform force distribution on the glass and avoiding localized stress concentration. The semi-circular head design of the adjusting screws further reduces friction, making operation smoother.

[0020] This escalator glass explosion-proof support device has a stable and durable structure. The barbed structure of the pad enhances the connection stability between the clamping parts and the rocker, while the sliding design of the rotating shaft and guide plate ensures the flexibility of the component movement and extends the service life of the device.

[0021] This escalator glass explosion-proof support device is easy to install. The cooperation between the guide plate and the spring allows the clamping parts to automatically open when no glass is placed and automatically lock after the glass is placed, which greatly improves the installation efficiency and facilitates subsequent fastening operations.

[0022] This escalator glass explosion-proof support device has a wide range of applications. Its structural design can be adapted to escalator glass of different thicknesses and sizes, making it highly versatile and practical. Attached Figure Description

[0031] Please see Figures 1-2 An explosion-proof support device for escalator glass includes a support body 1, the support body 1 includes an opening 101, the opening 101 is opened on the top of the support body 1, and an installation arm 102 is fixedly connected to one side of the support body 1.

[0032] The opening 101 is equipped with a clamping member 2. The clamping member 2 is a U-shaped elastic plastic plate. An adjustable clamping space is formed between the two side plates of the clamping member 2. One side of the clamping member 2 is fixed to the inner wall of one side of the opening 101, and the other side is equipped with a pad 4.

[0033] A rocker arm 5 is provided on one side of the pad 4. Both the pad 4 and the rocker arm 5 are located inside the opening 101. The pad 4 is configured as a barb structure with one side being a vertical surface and the other side being an inclined surface. The vertical surface of the pad 4 is fixed to the outer wall of the other side of the clamping member 2, and the inclined surface is fixed to the rocker arm 5.

[0034] The rocker arm 5 is configured with a bent structure. An adjusting screw 3 is installed on the vertical section of the rocker arm 5. The adjusting screw 3 is threaded onto the support body 1. One end of the adjusting screw 3 has a semi-circular head structure and abuts against the vertical section of the rocker arm 5. Thus, when one end of the adjusting screw 3 abuts against the rocker arm 5, the clamping space on the clamping member 2 is adjustable via the pad 4. The other end of the adjusting screw 3 is an operating end used to rotate the adjusting screw 3. The support body 1 has at least two adjusting screws 3 arranged in staggered positions.

[0035] The lower end of the vertical plate portion and the horizontal plate portion of the rocker 5 pass through the bracket body 1 and are located inside the mounting groove 9. There is an movable gap between the lower end of the vertical plate portion of the rocker 5 and the bracket body 1. The mounting groove 9 is opened inside the bottom end of the bracket body 1, and the opening of the mounting groove 9 is sealed by the sealing block 10.

[0036] The bend of the rocker 5 is rotatably connected to the inside of the mounting groove 9 via the rotating shaft 6. A guide plate 7 is fixedly installed at one end of the horizontal plate of the rocker 5. The upper end of the guide plate 7 is a flat plate structure, and the lower end is a single or multiple column structure. The guide plate 7 passes through the horizontal plate of the rocker 5, and its upper flat plate structure passes through the bottom of the bracket body 1 and the clamping member 2 to make contact. The upper flat plate structure is slidably connected to the bracket body 1. A spring 8 is sleeved on the outside of the lower column structure. One end of the spring 8 abuts against the bottom of the horizontal plate of the rocker 5, and the other end abuts against the sealing block 10.

[0037] Specifically, in use, when the escalator glass is not placed inside the clamping member 2, the guide plate 7, under the combined action of the spring 8 and the rocker plate 5, the spring 8 pushes against the horizontal part of the rocker plate 5, causing the guide plate 7 to be lifted upward. The guide plate 7 can lift the bottom of the clamping member 2 slightly. At the same time, the vertical part of the rocker plate 5 can be deflected based on the rotating shaft 6 and lean against the inner wall of the opening 101. The vertical part of the rocker plate 5 pulls the right side of the clamping member 2 open through the pad 4, making the opening of the clamping member 2 larger.

[0038] When the escalator glass is placed inside the clamping member 2, the escalator glass presses down on the clamping member 2, causing the guide plate 7 to move downwards as well. The spring 8 is compressed, and the horizontal part of the rocker plate 5 is pressed back to its original position. The vertical part can be deflected back based on the rotating shaft 6. At the same time, the vertical part of the rocker plate 5 presses down on the right side of the clamping member 2 to the left through the pad 4, clamping the escalator glass and achieving an automatic locking effect. This achieves temporary fixed installation and positioning of the escalator glass, facilitating subsequent fastening work. Finally, the escalator glass is clamped and fixed inside the clamping member 2 by one end of the adjusting screw 3 pressing against the rocker plate 5.

[0039] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
