Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof display technology, and in particular relates to an explosion-proof display for mining that can be opened and closed from top to bottom. Background Technology

[0002] An explosion-proof display is a special type of display device that can be used safely in hazardous environments such as those with flammable and explosive gases and dust. It prevents potential explosions caused by internal electrical sparks, high temperatures, or other factors. Its casing typically uses special explosion-proof materials and structural designs, providing excellent sealing and explosion-proof performance.

[0003] When performing maintenance on explosion-proof displays, it is necessary to separate the sealing cover from the housing. During subsequent installation, realignment is required, making the installation process cumbersome. Furthermore, the openable type of explosion-proof display makes it inconvenient to maintain a suitable open position for operation. Therefore, it is necessary to provide a top-and-bottom opening explosion-proof display for mining, which uses an up-and-down rotating opening and closing mechanism to facilitate alignment during installation. It is also equipped with a temporary suspension locking structure to keep the sealing cover at a suitable maintenance angle, making it convenient for users to maintain the display. Utility Model Content

[0004] The purpose of this utility model is to provide a mine explosion-proof display that opens and closes vertically. It adopts an up-and-down rotating opening and closing method, which facilitates alignment during installation. It is also equipped with a temporary locking structure to keep the sealing cover at a suitable maintenance angle, making it convenient for users to maintain the display, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A mine explosion-proof display with an up-and-down opening mechanism includes an explosion-proof shell: an explosion-proof cover is provided on the front side of the explosion-proof shell, and multiple screws are provided through the front side of the explosion-proof cover. The explosion-proof shell and the explosion-proof cover are fixedly connected by screws. A display screen is fixedly installed in the inner cavity of the explosion-proof shell, and tempered glass is fixedly installed in the inner cavity of the explosion-proof cover. A fixing plate is fixedly connected to the right side of the top of the explosion-proof shell. A rotating plate is rotatably connected to the front side of the fixing plate. The rotating plate is fixedly connected to the explosion-proof cover. A locking assembly is provided on the right side of the fixing plate. The locking assembly includes a sliding pin slidably connected to the inner cavity of the fixing plate. A limit button is fixedly connected to the left side of the bottom of the sliding pin. Limiting slots adapted to the limit button are provided on the bottom and front side of the left side of the rotating plate. A spring is sleeved on the surface of the sliding pin.

[0006] Preferably, a hinge is fixedly connected to the top left side of the explosion-proof housing, and the end of the hinge away from the explosion-proof housing is fixedly connected to the explosion-proof cover.

[0007] Preferably, the top and bottom of the sliding pin are welded with limit sliders, and the top and bottom of the fixing plate are provided with limit grooves that are adapted to the limit sliders.

[0008] Preferably, the two ends of the spring are in contact with the inner wall of the fixed plate and the surface of the limiting slider, respectively.

[0009] Preferably, an inner support plate is fixedly connected to the front side of the explosion-proof shell, and a sealing ring is fitted on the surface of the inner support plate.

[0010] Preferably, handles are fixedly connected to both ends of the front side of the explosion-proof cover.

[0011] The beneficial effects of the utility model are:

[0012] 1. This utility model uses the combination of explosion-proof cover and tempered glass to shield and protect the front side of the explosion-proof shell. At the same time, with the cooperation of fixed plate, rotating plate and locking component, while ensuring that the explosion-proof cover and explosion-proof shell can rotate relative to each other, the position of the explosion-proof cover can also be relatively locked when opening and closing the explosion-proof cover. This achieves the purpose of being able to be suspended for easy maintenance and inspection and being able to be temporarily locked for easy alignment and installation.

[0013] 2. This utility model uses the combination of a limiting slider and a limiting groove to elastically push the sliding pin, allowing the sliding pin to slide actively to the right, thereby driving the limiting convex button to actively engage in the inner cavity of the limiting groove, thus limiting and locking the rotating plate and the explosion-proof cover.

[0014] 3. This utility model uses the inner support plate and sealing ring together to further seal the explosion-proof shell and the explosion-proof cover, thereby improving the sealing effect of the explosion-proof cover on the explosion-proof shell. Attached Figure Description

[0022] In the following description, embodiments of the opening and closing type explosion-proof display for mining according to the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates an embodiment of a top-and-bottom opening explosion-proof display for mining applications, comprising an explosion-proof housing 1; an explosion-proof cover 2 is provided on the front side of the explosion-proof housing 1; an inner support plate 8 is fixedly connected to the front side of the explosion-proof housing 1; a sealing ring 9 is fitted on the surface of the inner support plate 8; through the cooperation of the inner support plate 8 and the sealing ring 9, the explosion-proof housing 1 and the explosion-proof cover 2 are further sealed, thereby improving the sealing effect of the explosion-proof cover 2 on the explosion-proof housing 1; a hinge 4 is fixedly connected to the left side of the top of the explosion-proof housing 1; the end of the hinge 4 away from the explosion-proof housing 1 is fixedly connected to the explosion-proof cover 2; handles 10 are fixedly connected to both ends of the front side of the explosion-proof cover 2; multiple screws are provided through the front side of the explosion-proof cover 2; the explosion-proof housing 1 and the explosion-proof cover 2 are fixedly connected by screws; a display screen 11 is fixedly installed in the inner cavity of the explosion-proof housing 1; tempered glass 3 is fixedly installed in the inner cavity of the explosion-proof cover 2; a fixing plate 5 is fixedly connected to the right side of the top of the explosion-proof housing 1; the front side of the fixing plate 5 is rotatably connected... A rotating plate 6 is connected to the explosion-proof cover 2. A locking assembly 7 is provided on the right side of the fixed plate 5. The locking assembly 7 includes a sliding pin 71 that is slidably connected to the inner cavity of the fixed plate 5. Limiting sliders 75 are welded to the top and bottom of the sliding pin 71. Limiting grooves 76 that are adapted to the limiting sliders 75 are provided on the top and bottom of the fixed plate 5. Through the cooperation of the limiting sliders 75 and the limiting grooves 76, the sliding pin 71 is elastically pushed forward, so that the sliding pin... 71 can slide actively to the right, thereby driving the limiting protrusion 72 to actively engage in the inner cavity of the limiting slot 73, thereby limiting and locking the rotating plate 6 and the explosion-proof cover 2. The limiting protrusion 72 is fixedly connected to the left side of the bottom of the sliding pin 71. The bottom and front sides of the left side of the rotating plate 6 are provided with limiting slots 73 that are adapted to the limiting protrusion 72. A spring 74 is sleeved on the surface of the sliding pin 71. The two ends of the spring 74 are in contact with the inner wall of the fixed plate 5 and the surface of the limiting slider 75, respectively.

[0024] Working principle: When using this utility model, the user removes the screw on the front side of the explosion-proof cover 2, and then pushes the sliding pin 71 to the left, causing it to slide. This causes the sliding pin 71 to drive the limiting protrusion 72 out of the inner cavity of the current limiting slot 73. At this time, the rotating plate 6 is released from its limit, and the spring 74 is compressed. Then, the user holds the handle 10 and rotates the explosion-proof cover 2 upwards. After the explosion-proof cover 2 rotates 90 degrees, the rotating plate 6 also rotates 90 degrees. At this time, the continuously compressed spring 74 drives the sliding pin 71 to slide back to the right, thereby allowing the explosion-proof cover 2 to slide upwards. The limiting protrusion 72 engages in the inner cavity of the current limiting slot 73, limiting and locking the rotating plate 6, while simultaneously allowing the explosion-proof cover 2 to be limited and suspended. At this time, the user can perform maintenance and inspection on the display screen 11. After the maintenance and inspection are completed, the user pushes the sliding pin 71 to the left again, allowing the rotating plate 6 to be released from the limiting position. After the explosion-proof cover 2 is engaged in the front side of the explosion-proof housing 1, the sliding pin 71 drives the limiting protrusion 72 to engage in the inner cavity of the limiting slot 73, temporarily fixing the position of the explosion-proof cover 2, making it easier for the user to install the screws at the end.

[0025] In summary, this top-and-bottom opening explosion-proof display for mining uses the explosion-proof cover 2 and tempered glass 3 to shield and protect the front of the explosion-proof housing 1. At the same time, with the cooperation of the fixing plate 5, the rotating plate 6 and the locking assembly 7, while ensuring the relative rotation of the explosion-proof cover 2 and the explosion-proof housing 1, the position of the explosion-proof cover 2 can also be relatively locked when opening and closing the explosion-proof cover 2. This achieves the purpose of being able to be suspended for easy maintenance and inspection and being able to be temporarily locked for easy alignment and installation.
