Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a protective device for an operating table. Background Technology

[0002] In metallurgical and other manufacturing industries, control panels are crucial equipment for controlling the entire production process. However, due to the complex factory environment, the buttons and indicator lights on control panels often face numerous problems such as wear, aging, and lack of protection. The labels on the buttons and indicator lights on the control panel, due to long-term exposure to the production environment, are prone to fading and peeling, making them difficult for operators to identify. In emergencies, operators may make operational errors due to unclear labeling, causing equipment damage or production accidents. Common protective devices are prone to baffle wear during use, resulting in high replacement costs; due to their large size and weight, it is also difficult for workers to open and close the protective covers with one hand. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems of common operating table protective devices in the prior art, such as easy wear and tear of the baffles during use, high replacement costs, and difficulty for workers to open and close the protective cover with one hand due to its large size and weight. The operating table protective device provided in this application consists of a protective cover set around the operating table, with the operating panel covered by an acrylic glass plate or a high-strength transparent material to ensure visibility; a damping device is set between the protective cover and the operating table to achieve smooth opening and closing; the damping device can make the protective cover close slowly and automatically when it is not completely closed, reducing manual intervention and avoiding the risk of impact or pinching caused by rapid falling.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a workbench protection device, comprising: a workbench, on which a protective cover is provided, the protective cover surrounding the upper surface of the workbench; one side of the protective cover is rotatably connected to the workbench, and a damping device is provided between the workbench and the protective cover, the damping device being used to buffer when the protective cover is closed. The protective cover uses acrylic glass or high-strength transparent material to cover the workbench panel, ensuring visibility. The protective cover uses a cable tray as a support frame, balancing structural stability and lightweight design. The upper baffle and the transparent panel can be independently disassembled for easy cleaning or maintenance. The overall modular design significantly extends the service life of the protective device while adapting to the installation requirements of different industrial environments.

[0005] Furthermore, the protective cover has a front baffle on the side furthest from its rotatable connection with the control panel; the front baffle extends downwards to the side of the control panel. The front baffle features a detachable design (including snap-fit ​​or magnetic connections), facilitating individual replacement of worn parts and reducing maintenance costs. The front baffle is equipped with an ergonomic, non-slip rubber handle, supporting one-handed operation and improving ease of opening and closing. Optimized weight distribution of the front baffle shifts the overall center of gravity of the protective cover forward, further accelerating its descent and ensuring rapid protection in emergency situations.

[0006] Furthermore, the damping device is a hydraulic hinge, and the protective cover is rotatably connected to the operating table via the hydraulic hinge.

[0007] Furthermore, the damping device is a gas spring, and both ends of the gas spring are rotatably connected to the protective cover and the operating table, respectively.

[0008] Furthermore, a transparent protective film is laid on the upper surface of the operating table. This polyurethane transparent protective film directly covers the buttons and indicator lights, preventing aging caused by friction, oil, or chemical corrosion. A replaceable label layer is affixed beneath the protective film to prevent fading or peeling due to long-term exposure, reducing the risk of misoperation. The edges of the protective film are secured with silicone sealing strips to ensure a tight fit and easy replacement.

[0009] Furthermore, the edges of the protective film are secured with silicone sealing strips.

[0010] Furthermore, an electromagnetic attraction device is provided at the bottom of the protective cover; the electromagnetic attraction device can adopt existing technology, such as setting an electromagnet at the bottom of the protective cover and setting a magnet on the operating table, and achieving attraction between the electromagnet and the magnet by energizing the electromagnet.

[0018] The technical solution of this utility model will now be clearly and completely described 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 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.

[0019] Example 1:

[0020] Please see Figure 1 This utility model provides a workbench protection device, comprising: a workbench 1, on which a protective cover 4 is disposed, the protective cover 4 surrounding the upper surface of the workbench 1; one side of the protective cover 4 is rotatably connected to the workbench 1, and a damping device 5 is disposed between the workbench 1 and the protective cover 4, the damping device 5 being used to buffer when the protective cover 4 is closed. The protective cover 4 uses an acrylic glass plate or a high-strength transparent material to cover the workbench panel, ensuring visibility. The protective cover 4 uses a cable tray as a support frame, balancing structural stability and lightweight design. The upper baffle and the transparent panel can be independently disassembled for easy cleaning or maintenance. The overall modular design significantly extends the service life of the protective device, while adapting to the installation requirements of different industrial environments.

[0021] In this embodiment, the protective cover 4 is positioned away from the side rotatably connected to the operating table 1 as a front baffle 2; the front baffle 2 extends downwards to the side of the operating table 1. The front baffle 2 features a detachable design (including snap-fit ​​or magnetic connections), facilitating individual replacement of worn parts and reducing maintenance costs. The front baffle 2 is equipped with a non-slip rubber handle 3, which is ergonomically designed, supports one-handed operation, and improves ease of opening and closing. The optimized weight distribution of the front baffle 2 shifts the overall center of gravity of the protective cover 4 forward, further accelerating its descent and ensuring rapid protection in emergency situations.

[0022] In this embodiment, the damping device 5 is a hydraulic hinge, and the protective cover 4 is rotatably connected to the operating table 1 via the hydraulic hinge. The hydraulic hinge is fixed to the side frame of the operating table 1 and the side of the protective cover 4 by bolts, forming a single-axis rotation structure with the protective cover 4. The hinge has a built-in adjustable damping valve, and the closing speed can be adjusted by a knob (adjustable from 1 to 5 seconds). The overall weight distribution of the protective cover 4 is optimized, with the center of gravity biased towards the front baffle 2, assisting in automatic closing. When the operator holds the handle 3 and lifts the protective cover 4 upwards, the hydraulic hinge provides initial assistance, reducing the opening force; the protective cover 4 can be suspended at any angle (0-90°) for easy operation. Closing process: When the protective cover 4 is released, the hydraulic hinge controls its slow descent to avoid impact; when it is close to complete closure (approximately 15° position), the damping force increases to ensure smooth closure. Emergency closing: The front baffle 2 extends downwards, and the center of gravity design allows the protective cover 4 to close quickly after release (completed within 2 seconds), while hydraulic buffering prevents impact damage. Safety Protection: Hydraulic buffer eliminates closing impact, preventing pinching or equipment damage. Effortless Operation: The hinge-assisted design reduces opening force by over 40%, allowing for one-handed operation. Environmental Adaptability: Corrosion-resistant materials and sealing structure are suitable for high-dust, humid, or corrosive environments. Easy Maintenance: Quick-release front baffle 2 and modular hinge design support partial replacement, reducing maintenance time by 50%. Long-Term Durability: The hydraulic system has a lifespan of ≥100,000 opening and closing cycles, and the overall service life of the protective cover 4 is increased by more than 3 times.

[0023] In this embodiment, a transparent protective film 6 is laid on the upper surface of the operating table 1. The polyurethane transparent protective film 6 directly covers the buttons and indicator lights, preventing aging caused by friction, oil stains, or chemical corrosion. A replaceable label layer is affixed beneath the protective film 6 to prevent fading or peeling due to long-term exposure and reduce the risk of misoperation. The edges of the protective film 6 are fixed with silicone sealing strips to ensure a tight fit and easy replacement. Further, the edges of the protective film 6 are fixed with silicone sealing strips.

[0024] Example 2:

[0025] Unlike the embodiments described above, the damping device 5 in this embodiment is a gas spring, such as... Figure 2The gas spring is rotatably connected at both ends to the protective cover 4 and the operating table 1, respectively. An electromagnetic attraction device is installed at the bottom of the protective cover 4. This electromagnetic attraction device can utilize existing technology, such as an electromagnet at the bottom of the protective cover 4 and a magnet on the operating table 1. Energizing the electromagnet allows for attraction between the electromagnet and the magnet. A nitrogen-filled gas spring (300mm stroke, 150N support force) is selected, with both ends rotatably connected to the base of the operating table 1 and the protective cover 4 via universal ball joint connectors. A silicone sealing strip is added to the edge of the protective cover 4, forming a dustproof and waterproof barrier with the operating table 1 when closed. When the protective cover 4 is closed, the gas spring is angled at 30°, with its upper end connected to the internal reinforcing ribs of the protective cover 4 and its lower end connected to the side of the operating table 1. A dual locking mechanism is employed: the gas spring has a built-in position locking function, working in conjunction with the electromagnetic attraction device (12V DC powered) at the bottom of the protective cover 4. The overall frame is constructed from aviation-grade aluminum profiles, and the connection nodes are secured with anti-loosening rivets. Opening Phase: Press the unlock button at handle 3 to de-energize and release the electromagnetic engagement device; apply slight upward force to start, with the gas spring providing 80% lift assistance; the protective cover 4 can hover at any angle from 30° to 85° (gas spring self-locking function); Closing Phase: When gently pushing the protective cover 4 below 30°, the gas spring switches to assist mode; the final 15° travel is actively pulled and positioned by the electromagnetic engagement device; the silicone sealing strip compresses to achieve IP54 protection rating upon closing; Emergency Mode: When the emergency stop button is triggered, the electromagnetic engagement device is instantly de-energized, and the gas spring assists in rapidly closing the protective cover 4 within 1.2 seconds. Effortless and Easy to Operate: The gas spring provides strong support, allowing for easy opening and closing with a light push of one hand, reducing operating force by 70%, and the hovering angle is freely adjustable. Rapid and Safe Protection: Automatic closure in 1 second in emergencies; the sealed design is dustproof and waterproof, suitable for high-risk environments. Applicable to nuclear power plant control rooms, semiconductor cleanrooms, and other locations with stringent requirements for operational precision and environmental cleanliness.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
