Description

Technical Field

[0001] The utility model relates to the technical field of mine switches, in particular to an anti-corrosion sealing structure of a mine remote-controlled bidirectional emergency stop switch. Background Art

[0002] The equipment in coal mines has a high safety level requirement, so emergency stop switches need to be installed on the equipment. When the equipment in the coal mine fails or an abnormal situation occurs during work, the emergency stop switch is used to immediately shut down the abnormal equipment to ensure the safety of the workers and machinery and equipment in the mine. The environment in the mine is complex, and water leaks, falling rocks, etc. may occur from time to time. In order to deal with similar situations, the emergency stop switch should have a corresponding protective structure.

[0003] In the prior art, a Chinese patent with publication number CN217690829U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an intelligent emergency stop switch for mining that is easy to install. The prior art limits the limit block through the limit grooves inside the front and rear sides of the casing at both ends, and then affects the position of the limit block inside by pulling the spring, so that the buckle can be engaged in the buckle inside the bayonet pin, thereby fixing and sealing the casing and the top cover, facilitating installation and disassembly, and solving the problem that the protective casing of a general switch is sealed by the top cover and bolts, and the bolts will oxidize after a long period of use, resulting in the inability to open and repair the interior.

[0004] However, the prior art only seals the protective housing of the switch by means of buckles and pins, resulting in poor sealing effect. Corrosive substances, dust, water and other pollutants in the environment can easily enter the interior of the switch, causing corrosion to the internal metal parts of the switch, thus affecting the use effect. Utility Model Content

[0005] The utility model aims to provide an anti-corrosion sealing structure of a remote-controlled two-way emergency stop switch for mining, so as to solve the problems raised in the above-mentioned background technology.

[0009] A further improvement of the technical solution of the utility model is that the inner wall of the limit receiving block is movably connected to the outer wall of the flip limit rod, the inner wall of the limit receiving block is provided with a plug-in hole, the inner wall of the plug-in hole is plugged with a magnetic plug-in rod for limiting and closing the flip limit rod, and the magnetic plug-in rod is magnetically adsorbed to the inner wall of the plug-in hole.

[0010] A further improvement of the technical solution of the utility model is that the inner wall of the threaded sleeve is threadedly connected to the outer wall of the threaded half ring.

[0011] A further improvement of the technical solution of the utility model is that the antistatic flexible film tube is made of transparent material.

[0012] A further improvement of the technical solution of the utility model is that: a docking groove is provided at the joint of the upper shell and the lower shell, and a drawstring is movably connected to the inner wall of the docking groove.

[0013] A further improvement of the technical solution of the utility model is that a rubber sealing ring is fixedly connected to the joints of the upper shell and the lower shell.

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present invention is further described in detail below in conjunction with the embodiments: Example 1

[0026] like Figure 1-5As shown, the utility model provides an anti-corrosion sealing structure of a remote-controlled two-way emergency stop switch for mining, including a protective housing 1, a fastening assembly 2, a mounting ring 3, a button sealing assembly 4 and a two-way emergency stop switch 5. The protective housing 1 includes an upper housing 6 and a lower housing 7 that are combined and docked with the outer wall of the two-way emergency stop switch 5. The outer walls of the upper housing 6 and the lower housing 7 are docked and fixedly connected with a threaded half ring 8. The button sealing assembly 4 includes a threaded sleeve 16 and an antistatic flexible membrane cylinder 17 that is fixedly connected to one end of the threaded sleeve 16. When the fastening assembly 2 is locked, the threaded sleeve 16 is sleeved on the outer wall of the button 18, and then the threaded sleeve 16 and the threaded half ring 8 are docked and tightened, and the top of the button 18 is just in contact with the inner wall of one end of the antistatic flexible membrane cylinder 17. When the button 18 is pressed, no corrosive substances, dust, water and other pollutants will enter its interior.

[0027] Fastening assemblies 2 are provided on both sides of the protective shell 1, and the fastening assemblies 2 include a mounting block 10 fixedly connected to one side of the lower shell 7 and a limit receiving block 12 fixedly connected to one side of the upper shell 6. The inner wall of the mounting block 10 is rotatably connected to a flip limit rod 11, and the top outer wall of the flip limit rod 11 is rotatably connected to an external rotating rod 15 movably connected to the outer wall of the limit receiving block 12.

[0028] The inner wall of the limit receiving block 12 is movably connected to the outer wall of the flip limit rod 11. The inner wall of the limit receiving block 12 is provided with a plug hole 13. The inner wall of the plug hole 13 is plugged with a magnetic plug rod 14 for limiting and closing the flip limit rod 11. The magnetic plug rod 14 is magnetically adsorbed to the inner wall of the plug hole 13. The connection between the magnetic plug rod 14 and the plug hole 13 can limit the position of the flip limit rod 11 to prevent the problem of poor sealing of the upper shell 6 and the lower shell 7 due to position deviation. Example 2

[0029] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the inner wall of the threaded sleeve 16 is threadedly connected to the outer wall of the threaded half ring 8, and the antistatic flexible membrane cylinder 17 is made of transparent material.

[0030] A docking groove 9 is provided at the joint of the upper shell 6 and the lower shell 7 , and a drawstring 19 is movably connected to the inner wall of the docking groove 9 .

[0031] The joints of the upper shell 6 and the lower shell 7 are fixedly connected with rubber sealing rings, and buttons 18 located inside the antistatic flexible membrane cylinder 17 are provided on both sides of the two-way emergency stop switch 5. When the two-way emergency stop switch 5 needs to be repaired, it is only necessary to pull out the magnetic plug rod 14, flip the limit rod 11 and toggle it to release the force between the mounting block 10 and the limit receiving block 12, and then remove the upper shell 6 for subsequent work.

[0032] At the same time, the inner wall of the docking groove 9 is filled with a part of the rubber sealing ring to achieve a sealing effect, and the interior of the docking groove 9 leaves space for the normal use of the pull rope 19.

[0033] The threaded half ring 8 and the threaded sleeve 16 are both made of plastic.

[0034] The following is a detailed description of the working principle of the anti-corrosion sealing structure of the mine-used remote-controlled two-way emergency stop switch.

[0035] like Figure 1-5 As shown, when in use, the two-way emergency stop switch 5 is first placed in the protective shell 1, and the upper shell 6 and the lower shell 7 are connected and closed. Then the staff will move the flip limit rod 11 to the position of the limit receiving block 12, and move the external rotating rod 15 to the position of the upper surface of the limit receiving block 12. At this time, the limit receiving block 12 and the mounting block 10 will approach each other under the limiting force of the external rotating rod 15 and the flip limit rod 11, and then drive the upper shell 6 and the lower shell 7 to move closer to each other, and squeeze the rubber sealing ring to make the connection between the two tighter, and then push the magnetic plug rod 14 into the inner wall of the plug hole 13, and the magnetic plug rod 14 will use magnetic force to adsorb on the inner wall of the plug hole 13. At the same time, the magnetic plug rod 14 will also limit the position of the flip limit rod 11 to prevent the flip limit rod 11 from shifting, resulting in the separation of the upper shell 6 and the lower shell 7.

[0036] When the fastening assembly 2 is locked, the threaded sleeve 16 is sleeved on the outer wall of the button 18, and then the threaded sleeve 16 is connected and tightened with the threaded half ring 8. At this time, the top of the button 18 just contacts the inner wall of one end of the antistatic flexible membrane tube 17. When the button 18 is pressed, no corrosive substances, dust, water and other pollutants will enter its interior.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
