Description

Technical Field

[0001] This invention relates to the field of display screen technology, specifically to an explosion-proof and dustproof display screen assembly suitable for industrial environments. Background Technology

[0002] In industrial production environments, displays are frequently used for equipment control, data monitoring, and process display, making them indispensable electronic devices. However, industrial environments present challenges such as high dust levels, significant risks of mechanical collisions, and frequent equipment vibrations. Traditional displays lack specialized protective structures, making them susceptible to dust entering the internal components and causing short circuits or damage to the display panel from impacts, severely impacting the lifespan and accuracy of the display.

[0003] Meanwhile, existing industrial displays often use simple outer shells for protection, which are inconvenient to install and remove, have poor heat dissipation, and lack stable connection between the protective structure and the display, making them prone to loosening during equipment vibration. Furthermore, traditional industrial displays are mostly fixed installations, making height adjustment difficult and movement inconvenient, failing to meet the flexible needs of different workstations and usage scenarios in industrial production. Therefore, there is an urgent need for a display component that is explosion-proof, dustproof, structurally robust, easy to install and remove, and flexibly adjustable to address the pain points of display usage in industrial environments. Summary of the Invention

[0004] The purpose of this invention is to provide an explosion-proof and dustproof display screen assembly suitable for industrial environments, in order to solve the problems mentioned in the background art, such as the susceptibility of traditional display screens to dust and impact damage in industrial environments, the inconvenience of disassembling and assembling protective devices, poor heat dissipation, and the difficulty in adjusting and moving the display screen height.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof and dustproof display screen assembly suitable for industrial environments, comprising a display screen, a protective shell disposed on the outer side of the display screen, mounting blocks fixedly connected to both the left and right ends of the back side of the display screen, a fixing frame fixedly connected to both the left and right ends of the back side of the protective shell, fixing bolts inserted into the fixing frames, and nuts sleeved on both the left and right ends of the fixing bolts, mounting plates fixedly connected to both the left and right ends of the rear end of the protective shell, a protective door hinged to the front surface of the protective shell, and connecting plates fixedly connected to both the upper and lower ends of the right side of the protective door, and tempered glass fixedly installed on the front surface of the protective door, with fixing plates fixedly connected to both the left and right sides of the tempered glass.

[0006] Preferably, the upper end of the protective shell is provided with an inverted V-shaped structure, and rubber protrusions are evenly distributed on all four sides of the interior of the protective shell. The other end of the rubber protrusions abuts against the outer side of the display screen. The inverted V-shaped structure can reduce the accumulation of dust on the upper end of the protective shell, and the rubber protrusions can buffer and protect the display screen, avoid hard collisions between the display screen and the protective shell due to vibration, and at the same time improve the connection and sealing between the two, reducing the entry of dust.

[0007] Preferably, the mounting block is inserted into the fixed frame, and the fixed frame has a slot for matching it. The fixing bolt is threaded into the mounting block and the fixed frame, and the mounting block and the fixed frame have slots for matching it. The two sets of nuts are close to each other on the outside of the fixed frame. The initial positioning of the display screen and the protective shell is achieved by the insertion and cooperation of the mounting block and the fixed frame. Then, the threads of the fixing bolt and the nuts are used to lock the connection between the two to ensure the stability of the connection. At the same time, this structure is easy to disassemble and assemble, which facilitates the inspection and replacement of the display screen.

[0008] Preferably, the protective shell has heat dissipation vents evenly distributed on the back side, and a dustproof net is fixedly connected to the heat dissipation vents. The heat dissipation vents can dissipate the heat generated by the display screen during operation in a timely manner, avoiding excessive internal temperature from affecting the service life of components. The dustproof net can prevent dust in the industrial environment from entering the protective shell while ensuring heat dissipation, thus achieving the dual effect of heat dissipation and dust prevention.

[0009] Preferably, the mounting plate is configured in an L-shape, with mounting holes at both the top and bottom of the rear side. The L-shape increases the contact area with the mounting surface, improving the stability of the installation. The mounting holes can accommodate various fasteners such as bolts and expansion bolts, making it easy to fix the component to different installation positions such as walls and equipment racks, thus meeting the diverse installation needs of industrial scenarios.

[0010] Preferably, the connecting plate and the protective door form an L-shaped structure. The left side of the connecting plate abuts against the outer surface of the protective shell. Locking bolts are inserted into both the connecting plate and the protective shell. A handle is fixedly connected to the middle of the right side of the protective door. The L-shaped connecting plate can improve the fit between the protective door and the protective shell. The locking bolt can lock and fix the protective door, preventing it from opening arbitrarily when the equipment vibrates or is touched by external force. The handle makes it easy for staff to open the protective door and operate and maintain the display screen.

[0011] Preferably, the back side of the tempered glass is movably engaged with the protective door, and connecting plates are distributed at the four corners of the tempered glass. Locking bolts are inserted into the connecting plates, and locking grooves that cooperate with the locking bolts are opened on the protective door. Double-layer explosion-proof glass is fixedly connected to the back side of the protective door, and the explosion-proof glass is set at the front of the display screen, while the tempered glass is located on the outside, which plays a role in resisting impact and scratches. The double-layer explosion-proof glass is close to the display screen, achieving professional explosion-proof protection. The double glass structure greatly improves the protection level of the display screen panel, and the tempered glass has a movable engaging structure, which is convenient for replacement after damage.

[0012] Preferably, mounting sleeves are fixedly connected to the lower left and right sides of the protective shell, and a support rod is inserted into the lower end of the mounting sleeve. A locking bolt is inserted into the front surface of the mounting sleeve, and a locking groove is opened on the support rod to cooperate with it. A base is fixedly connected to the lower end of the support rod, and locking casters are fixedly installed at the four corners of the lower surface of the base. The support rod can slide up and down in the mounting sleeve to realize flexible adjustment of the height of the display screen. The locking bolt and the locking groove can fix the adjusted height. The base improves the support stability of the overall structure, and the locking casters facilitate the movement and position fixation of this component. The staff can move it to different work positions according to the usage needs. After moving, the locking casters can ensure the stability during use.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: This explosion-proof and dustproof display screen assembly suitable for industrial environments constructs a multi-layered, three-dimensional protective structure through a protective shell, a protective door, reinforced glass, and double-layer explosion-proof glass. This achieves both explosion-proof and impact-resistant effects while effectively preventing industrial dust from contacting the display screen, solving the problem of traditional displays screens being easily damaged in industrial environments. The rubber protrusions inside the protective shell not only buffer and reduce shock but also improve sealing. The heat dissipation vents and dustproof mesh on the back side address both heat dissipation and dust prevention needs, preventing short-circuit failures of the display screen due to high temperatures or dust. The display screen and protective shell are connected by mounting blocks, fixing frames, and fixing bolts, making assembly and disassembly convenient and facilitating later inspection and maintenance. The L-shaped mounting plate adapts to various installation scenarios, improving installation flexibility. At the same time, the height adjustment structure at the bottom of the protective shell and the base with locking casters enable flexible adjustment of the display screen height and convenient overall movement, solving the problems of fixed installation and inconvenience of traditional industrial displays. The overall structure is reasonably designed and highly stable. All components work together to fully adapt to the complex usage requirements of industrial environments, effectively extending the service life of the display screen and improving the efficiency and safety of display screen use in industrial production.

[0014] Working principle When using this component, you can choose to install it in a fixed position or move it around depending on your installation needs. If you choose to install it in a fixed position, use the mounting holes on the mounting plate and fasteners such as bolts to fix the component to the wall, equipment rack, or other designated locations. If you choose to move it around, unlock the locking casters on the base and push the protective shell to move the component to the target workstation. After moving the component, lock the casters to ensure stability during use.

[0015] Before use, the height of the display screen can be adjusted according to the operating height requirements of the staff. Pull out the locking bolt on the mounting sleeve, push the protective shell to make the mounting sleeve slide up and down on the support rod, and after adjusting to a suitable height, insert the locking bolt into the locking groove of the mounting sleeve and the corresponding position of the support rod to complete the height fixation.

[0016] When the display screen is in operation, the protective shell provides overall protection for the display screen body. The internal rubber strips buffer the impact of equipment vibration and prevent hard collisions between the display screen and the protective shell. The inverted V-shaped structure at the top of the protective shell reduces dust accumulation, and the heat dissipation vents on the back side dissipate the heat generated by the display screen during operation. The dust filter prevents dust from entering the interior of the protective shell. The protective door is locked to the protective shell by a connecting plate and locking bolt. The outer tempered glass is impact-resistant and scratch-resistant, while the inner double-layer explosion-proof glass provides explosion protection for the display screen panel. The double glass structure ensures that the display screen panel is not damaged in the industrial environment, and the staff can clearly see the content of the display screen through the glass.

[0017] When the display screen needs to be inspected, operated, or the tempered glass replaced, pull out the locking bolt on the connecting plate, grasp the handle and flip it outward to open the protective door, and then proceed with the subsequent operations; if the display screen needs to be disassembled, unscrew the nuts at both ends of the fixing bolt, pull out the fixing bolt, and the display screen can be pulled out of the fixing frame of the protective shell along with the mounting block. The disassembly and assembly process is convenient and does not require complicated tools.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-6 The present invention provides a technical solution: an explosion-proof and dustproof display screen assembly suitable for industrial environments, including a display screen 1, a protective shell 2 provided on the outer side of the display screen 1, mounting blocks 3 fixedly connected to both the left and right ends of the back side of the display screen 1, a fixing frame 4 fixedly connected to both the left and right ends of the back side of the protective shell 2, fixing bolts 5 inserted into the fixing frame 4, and nuts 6 sleeved on both the left and right ends of the fixing bolts 5, mounting plates 7 fixedly connected to both the left and right ends of the rear end of the protective shell 2, a protective door 8 hinged to the front surface of the protective shell 2, and connecting plates 9 fixedly connected to both the upper and lower ends of the right side of the protective door 8, and tempered glass 10 fixedly installed on the front surface of the protective door 8, and fixing plates 11 fixedly connected to both the left and right sides of the tempered glass 10.

[0021] The upper end of the protective shell 2 is designed with an inverted V-shape. Rubber protrusions are evenly distributed on all four sides of the interior of the protective shell 2, and the other end of the rubber protrusions abuts against the outside of the display screen 1. The inverted V-shape design can effectively reduce the accumulation of dust on the upper end of the protective shell 2 in the industrial environment and reduce the probability of dust entering the interior of the protective shell 2. The rubber protrusions are made of wear-resistant and elastic rubber material, which can buffer the display screen 1 when the equipment vibrates, and prevent hard collisions between the display screen 1 and the protective shell 2 that could damage the components. At the same time, the contact and fit of the rubber protrusions also improves the sealing performance between the protective shell 2 and the display screen 1.

[0022] Mounting block 3 is inserted into fixed frame 4, and fixed frame 4 has a slot for it to cooperate with. Fixing bolt 5 is threaded into mounting block 3 and fixed frame 4, and mounting block 3 and fixed frame 4 have slots for them to cooperate with. The two sets of nuts 6 are close to each other on the outside of fixed frame 4. Mounting block 3 and display screen 1 are integrally formed. Fixed frame 4 and protective shell 2 are welded and fixed. During installation, mounting block 3 is inserted into the slot of fixed frame 4 to complete the initial positioning of display screen 1 and protective shell 2. Then, fixing bolt 5 is passed through the slot of fixed frame 4 and mounting block 3. Nuts 6 are tightened at both ends of fixing bolt 5. The contact force between nuts 6 and fixed frame 4 is used to lock display screen 1 and protective shell 2. This connection structure has high stability, and disassembly and assembly only require tightening nuts 6 and pulling out fixing bolt 5, which facilitates the inspection and replacement of display screen 1.

[0023] The protective shell 2 has uniformly distributed heat dissipation vents on its back side, and a dustproof mesh is fixedly connected to the heat dissipation vents. The heat dissipation vents are rectangular through holes, which are evenly distributed in the lower middle part of the back side of the protective shell 2, corresponding to the positions of the heat-generating components of the display screen 1, so as to quickly dissipate heat. The dustproof mesh is made of metal wire mesh with a mesh count of 80-100 mesh, which can effectively block industrial dust, iron filings and other debris from entering the interior of the protective shell 2, while not affecting air circulation, thus achieving a balance between heat dissipation and dust prevention, and preventing the display screen 1 from malfunctioning due to high temperature or dust short circuit.

[0024] Mounting plate 7 is designed in an L-shape. Mounting holes are provided at both the top and bottom of the rear side of mounting plate 7.

The L-shape structure makes it form a surface contact with the mounting surface, which provides stronger support stability compared to traditional point or line connections. The mounting holes are countersunk holes with a diameter suitable for M8-M10 bolts. This component can be fixed to different positions such as walls, equipment racks, and operating tables by bolts according to installation requirements, adapting to diverse installation scenarios in industrial production.

[0025] The connecting plate 9 and the protective door 8 form an L-shaped structure. The left side of the connecting plate 9 abuts against the outer surface of the protective shell 2. Locking bolts are inserted into both the connecting plate 9 and the protective shell 2. A handle is fixedly connected to the middle of the right side of the protective door 8. The connecting plate 9 and the protective door 8 are integrally formed structures. The protective door 8 and the protective shell 2 are hinged by hinges made of stainless steel to improve service life. After the protective door 8 is closed, the inner side of the connecting plate 9 and the outer surface of the protective shell 2 are tightly fitted. By inserting the locking bolt into the holes of the connecting plate 9 and the protective shell 2, the protective door 8 can be locked, preventing the protective door 8 from being opened arbitrarily when the equipment vibrates or is touched by external force. The handle is a plastic non-slip handle, which is convenient for staff to grip and open the protective door 8.

[0026] The back of the reinforced glass 10 is movably engaged with the protective door 8. Connecting plates 9 are distributed at the four corners of the reinforced glass 10, and locking bolts are inserted into the connecting plates 9. The protective door 8 has locking grooves that cooperate with the locking bolts.
