Description
Technical Field
[0001] This utility model relates to the field of mining display technology, and in particular to an intrinsically safe display for mining applications. Background Technology
[0002] In modern mining production, mine displays serve as crucial monitoring and operational auxiliary equipment, directly impacting the safety and efficiency of mine operations. With the advancement of intelligent mine construction, higher demands are being placed on the reliability, protective performance, and adaptability to complex environments of mine displays. Mine displays must not only withstand harsh conditions such as high humidity, dust, and vibration within the mine, but also possess excellent sealing and stability to ensure reliable operation over long-term use.
[0003] In existing technologies, mining displays typically employ an open structure, with the screen directly exposed to the outside and protected only by a simple casing. While this design can meet basic display functions to some extent, the screen is susceptible to corrosion from dust, moisture, and other contaminants in the complex mining environment, leading to decreased display quality or even damage. Furthermore, the cable connections lack effective sealing measures, making them prone to water ingress or loosening, which can affect the normal operation of the display.
[0004] In existing technologies, the protective structures of mining displays mostly only provide basic dust and water protection, failing to effectively cope with the complex environmental changes within mines. Especially in terms of screen protection and cable sealing, existing solutions are significantly inadequate and cannot meet the requirements for high-reliability mining displays.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0043] This embodiment relates to an intrinsically safe display for mining applications. In terms of overall structure, as follows... Figure 1 and Figure 2 As shown, it includes a box body 1, a box cover 2, a screen 3, and a sealing joint 4.
[0044] The cover 2 is hinged to one side of the body 1. A through groove 5 is provided on the cover 2. Tempered glass 6 is installed in the through groove 5. The screen 3 is installed in the through groove 5 on one side of the tempered glass 6. A sealing connector 4 is provided for the cable to pass through and is installed at the rear of the cover 2. A protective cover 7 is provided on the cover 2 at the screen 3.
[0045] It is worth mentioning that the cover 2 and the body 1 can be connected by hinges, and the other side can be connected by a latch. This method is a common connection and locking accessory in the prior art. The cover 2 has an annular groove 8 around the through groove 5. The tempered glass 6 is pasted on the annular groove 8 to seal the through groove 5. The screen 3 is also installed in the annular groove 8, located on one side of the tempered glass 6. Therefore, the tempered glass 6 can protect the screen 3. The sealing connector 4 can seal the connected cables and pass them into the body 1. It also facilitates the disassembly and assembly of the cables. The protective cover 7 can better protect the screen 3. The protective cover 7 can completely cover the through groove 5.
[0046] Based on the above overall introduction, this embodiment presents an exemplary structure of an intrinsically safe display for mining applications, such as... Figure 3 As shown, the protective cover 7 has through holes 9 at irregular positions, and a support post 10 for supporting the screen 3 is screwed into the through hole 9. It should be noted that the through hole 9 can be drilled at different positions, and the support post 10 is inserted into the through hole 9. The inserted end of the support post 10 abuts against the screen 3. This setting ensures that the screen 3 is more stable after installation. The screen 3 is a common display screen 3 in the prior art, which will not be explained in detail here.
[0047] As a preferred option, such as Figure 4 As shown, the support column 10 in this embodiment includes a cylinder 1001 screwed into a through hole 9 and a telescopic column 1002 telescopically disposed within the cylinder 1001 and abutting against the screen 3. Specifically, the position of the through hole 9 is opened according to different positions of the screen 3, and the different positions are to avoid the components or vulnerable parts of the screen 3. The thread on the cylinder 1001 is the same as the thread on an ordinary screw. The cylinder 1001 is screwed into the through hole 9. The support force of the telescopic column 1002 varies depending on the depth to which the cylinder 1001 is screwed. The diameter of the through hole 9 is slightly smaller than the diameter of the cylinder 1001 to ensure that the cylinder 1001 can stay in the preset position.
[0048] Preferably, in this embodiment, a spring 1003 supporting the telescopic column 1002 is provided between the telescopic column 1002 and the cylinder 1001, and a disc 1004 is provided on the telescopic column 1002 to prevent it from detaching from the cylinder 1001. It should be noted that the groove in the center of the cylinder 1001 is not through-hole. The spring 1003 is located within the groove of the cylinder 1001. When the cylinder 1001 rotates towards the screen 3, the telescopic column 1002 abuts against the screen 3. At this time, the spring 1003 is under force, ensuring that the telescopic column 1002 always abuts against the screen 3, thereby protecting the screen 3. A retaining ring is provided on the groove of the cylinder 1001. The disc 1004 moves within the groove of the cylinder 1001 and stops when it abuts against the retaining ring, preventing the telescopic column from detaching from the groove of the cylinder 1001.
[0049] As a preferred option, such as Figure 5 and Figure 6As shown, the sealing connector 4 in this embodiment includes a spool 401 fixedly disposed at the rear of the housing 1 and a soft sleeve 402 inserted inside the spool 401. The cable is inserted into the soft sleeve 402, and a locking nut 403 is screwed onto the spool 401 to tighten the soft sleeve 402 onto the cable. Specifically, the spool 401 can be welded to the housing 1, or it can pass through the housing 1 and be fixed to the housing 1 by nuts, depending on the actual situation. Fixing with nuts means that a wire hole is opened in the housing 1, the spool 401 is inserted into the wire hole, and the outer surface of the spool 401 is threaded. Two nuts are located on the inner and outer sides of the wall of the housing 1, respectively. Through the threaded connection with the spool 401, the spool 401 is fixed to the housing 1. The soft sleeve 402 is bent outward and has a retaining ring. An annular groove 8 for retaining the retaining ring is opened on the inner surface of the spool 401 to prevent the soft sleeve 402 from coming off the spool 401. The movement of the locking nut 403 can keep the soft sleeve 402 tightly against the cable.
[0050] As a preferred option, such as Figure 6 As shown, in this embodiment, a clamping claw 404 is provided at the end of the cable drum 401 away from the housing 1. One side of the lock nut 403 is screwed to the cable drum 401, and the other end is attached to the clamping claw 404. It should be noted that one end of the clamping claw 404 is inserted into the cable drum 401, and the other end is outside the cable drum 401. The soft sleeve 402 is inserted into the clamping claw 404. The other end of the lock nut 403, that is, the end of the lock nut 403 away from the cable drum 401, is bent towards the center. The bend is in contact with the clamping claw 404. By moving the lock nut 403, the clamping claw 404 is pushed to close, thereby controlling the soft sleeve 402 and the cable to be tightly attached. The end of the clamping claw 404 outside the cable drum 401 is tilted towards the center to ensure that the soft sleeve 402 can be tightly attached to the cable.
[0051] The intrinsically safe display for mining applications in this embodiment effectively protects the screen 3 from damage caused by dust, moisture, and vibration by using tempered glass 6 and a protective cover 7, thus improving the reliability of the display in harsh environments. The sealing joint 4 and cable spool 401 structure ensure reliable cable sealing, preventing moisture and dust from entering the housing 1 and further enhancing the display's sealing performance. The support column 10 and spring 1003 structure enhance the installation stability of the screen 3, preventing it from loosening or being damaged due to vibration. The flexible placement and size of the through hole 9 further improves the applicability and reliability of the display.
[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
