Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, specifically a multi-hole wiring alarm gas detector that is quick to assemble and disassemble. Background Technology

[0002] A gas detector is an instrument for detecting gas concentration. It is suitable for hazardous locations where flammable or toxic gases are present. It can continuously detect the concentration of the gas in the air within the lower explosive limit for a long period of time and is widely used in industrial production.

[0003] Existing gas detectors have cumbersome wiring, and their drawbacks are even more pronounced in industrial areas where they are widely used, consuming a lot of manpower and time. Therefore, it is necessary to design a multi-hole wiring alarm gas detector that is practical and quick to install and disassemble. Utility Model Content

[0004] The purpose of this invention is to provide a multi-hole wiring alarm gas detector that is quick to install and disassemble, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-hole wiring alarm gas detector that is quick to assemble and disassemble, comprising a detector body, characterized in that: a fixing ring is welded and fixed to one side of the detector body, a rotating shaft is welded and fixed around one side of the detector body, a pressure plate is movably connected to the outer side of the rotating shaft, a locking ring is welded and fixed to one side of the detector body, and a pressure coil is movably connected to one side of the detector body. Three wires to be connected to the gas detector are respectively inserted into the three holes of the fixing ring, and the pressure coil is pushed towards the center of the detector body. During the movement, the pressure coil gradually contacts the pressure plate and exerts downward pressure on the pressure plate. The pressure plate, under pressure, rotates around the rotating shaft on one side and contracts inward on the other side, exerting pressure on the three wires inside the fixing ring. When the protruding part of the pressure coil enters the recess of the locking ring, the pressure coil is rotated clockwise, so that the pressure coil and the locking ring are fully engaged. At this time, the pressure of the pressure coil on the pressure plate is at its maximum, so that the three wires inside the fixing ring are completely clamped, facilitating quick wiring and tightening without the need to tighten each wire individually with a screw, saving time.

[0006] According to the above technical solution, a return spring is welded and fixed around the perimeter of the fixing ring. The pressure plate is movably connected to the return spring. A pressure shaft 1 is movably connected to both sides of the fixing ring, and a pressure shaft 2 is movably connected to both sides of the fixing ring. The pressure plate is movably connected to pressure shaft 1 and pressure shaft 2. When the pressure plate contracts inward under the pressure of the pressure coil, the return spring contracts under the pressure of the pressure plate. The pressure plate contacts pressure shaft 1 and pressure shaft 2 and transmits downward pressure. Pressure shaft 1 and pressure shaft 2 move inward under the influence of pressure to press the three wires. When it is necessary to change the installation position and pull out the three wires, the pressure coil is rotated counterclockwise to release the engagement with the locking ring and push the pressure coil to move in the opposite direction to the center of the detector body. The pressure coil gradually reduces the pressure on the pressure plate, the return spring gradually returns to its original state, and the pressure plate is pushed upward by the elastic force of the return spring. Pressure shaft 1 and pressure shaft 2 are no longer under downward pressure, and the three wires can be easily pulled out, facilitating quick replacement of the gas detector position.

[0007] According to the above technical solution, the pressure coil is connected to the locking ring. A locking spring is welded and fixed around the locking ring. A locking block is fixedly connected to one side of the locking spring. The locking block is movably connected to the locking ring. When the pressure coil and the locking ring are engaged, the locking block moves inward into the locking ring under the pressure of the pressure coil. The locking spring contracts under the pressure of the locking block. When the pressure coil and the locking ring finish rotating clockwise, the pressure coil is released, the locking spring loses pressure and rebounds, causing the pressure coil to move under the elastic force of the locking spring. The protrusion of the pressure coil enters the groove of the locking ring, which facilitates the complete engagement and locking of the pressure coil and the locking ring, and avoids the situation of the pressure coil loosening.

[0008] According to the above technical solution, a limiting spring is fixedly installed on one side of the detector body, and a limiting block is movably connected to one side of the detector body. The limiting spring and the limiting block are movably connected, and the limiting block is fixed in cooperation with the pressure coil. When it is necessary to change the position of the detector, the pressure coil is rotated to release the cooperation with the locking ring, and the pressure coil is dragged away from the locking ring. The pressure coil contacts the limiting block and applies pressure to the limiting block. The limiting block moves downward under pressure, causing the limiting spring to contract. When the pressure coil contacts the detector body, the protruding part of the limiting block enters the slot of the pressure coil, the limiting spring loses pressure and rebounds, and the protruding part of the limiting block moves upward and enters the slot of the pressure coil, so that the pressure coil cannot move axially. When it is necessary to rewire, the limiting block is pressed down, and the pressure coil can be pushed again, which helps to prevent the pressure coil from moving arbitrarily when it is not wired.

[0009] According to the above technical solution, a lower contact piece is welded and fixed to one side of the fixing ring, and torsion springs are welded and fixed to both sides of the lower contact piece. An upper contact piece is welded and fixed to the upper side of the torsion spring. When three wires are inserted into the fixing ring, the three wires touch the upper contact piece and squeeze to apply pressure. The torsion spring is deformed by the pressure of the upper contact piece, so that the three wires pass through the middle of the upper and lower contact pieces. After the insertion stops, the upper and lower contact pieces are clamped by the elastic force of the torsion spring to conduct electricity, which makes it easy for the wires of different thicknesses to contact the contact piece to complete the power conduction function.

[0010] According to the above technical solution, a first pressure spring is welded and fixed to both sides of the fixing ring, and a second pressure spring is welded and fixed to both sides of the fixing ring. The first pressure spring is movably connected to the first pressure shaft, and the second pressure spring is movably connected to the second pressure shaft. When the first and second pressure shafts move downward under the pressure of the pressure plate, the first and second pressure springs contract under pressure. When the pressure coil is disengaged from the locking ring, the first and second pressure shafts lose pressure, and the first and second pressure springs rebound, causing the first and second pressure shafts to move upward. This allows the first and second pressure springs to play a protective role in preventing the wire from being pinched and broken when the wire is tightened. When the wire is loosened, the first and second pressure springs play a reset role, making it easy to pull out the wire.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0012] (1) By setting the pressure of the pressure coil on the pressure plate, the circuit can be quickly pressed and positioned after insertion, and the circuit can be quickly released and pulled out when changing the position of the detector, saving time.

[0013] (2) By setting up the cooperation of the pressure coil, the locking ring and the locking block, it can be achieved that after the line is pressed, the pressure coil can be fully cooperated and fixed with the locking ring, and the line will not be loosened due to the movement of the pressure coil, thus avoiding the risk of poor line contact.

[0014] (3) By setting up upper contact piece, lower contact piece and torsion spring, it is possible to achieve complete contact between the contact piece and the line when the line thickness is different, thus avoiding the line connection failure caused by the line not being able to fully contact the contact piece due to the different line thickness.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a multi-hole wiring alarm gas detector that is quick to assemble and disassemble, comprising a detector body 1, characterized in that: a fixing ring 2 is welded and fixed to one side of the detector body 1; a rotating shaft 8 is welded and fixed around one side of the detector body 1; a pressure plate 4 is movably connected to the outer side of the rotating shaft 8; a locking ring 5 is welded and fixed to one side of the detector body 1; and a pressure coil 3 is movably connected to one side of the detector body 1. The three wires to be connected to the gas detector are respectively inserted into the three holes of the fixing ring 2, and the pressure coil 3 is pushed towards the center of the detector body 1. As the device moves, the pressure coil 3 gradually comes into contact with the pressure plate 4 and exerts downward pressure on the pressure plate 4. Under this pressure, one side of the pressure plate 4 rotates around the rotating shaft 8, while the other side contracts inward to exert pressure on the three wires inside the fixing ring 2. When the protruding part of the pressure coil 3 enters the recess of the locking ring 5, the pressure coil 3 is rotated clockwise so that the pressure coil 3 and the locking ring 5 are fully engaged. At this time, the pressure of the pressure coil 3 on the pressure plate 4 is at its maximum, so that the three wires inside the fixing ring 2 are completely clamped, which facilitates quick wiring and fastening without the need to use screws to fasten each wire individually, saving time.

[0022] A return spring 9 is welded and fixed around the perimeter of the fixed ring 2. The pressure plate 4 is movably connected to the return spring 9. A first pressure shaft 10 and a second pressure shaft 15 are movably connected to both sides of the fixed ring 2. The pressure plate 4 is movably connected to both the first and second pressure shafts 10 and 15. When the pressure plate 4 contracts inward under the pressure of the pressure coil 3, the return spring 9 contracts under the pressure of the pressure plate 4. The pressure plate 4 contacts the first and second pressure shafts 10 and 15, transmitting downward pressure. The first pressure shaft 10 and the second pressure shaft 15... Shaft 2 15 moves inward under pressure to press the three wires. When it is necessary to change the installation position and pull out the three wires, rotate the pressure coil 2 counterclockwise to release the engagement with the locking ring 5, push the pressure coil 3 to move in the opposite direction to the center of the detector body 1, the pressure coil 2 gradually reduces the pressure on the pressure plate 4, the return spring 9 gradually returns to its original state, the pressure plate 4 is pushed upward by the elastic force of the return spring 9, the wire pressing shaft 10 and the wire pressing shaft 2 15 are no longer under downward pressure, the three wires can be easily pulled out, which facilitates the quick change of the gas detector position;

[0023] The pressure coil 3 is connected to the locking ring 5. A locking spring 18 is welded and fixed around the locking ring 5. A locking block 17 is fixedly connected to one side of the locking spring 18. The locking block 17 is movably connected to the locking ring 5. When the pressure coil 3 and the locking ring 5 are engaged, the locking block 17 moves into the locking ring 5 under the pressure of the pressure coil 3. The locking spring 18 contracts under the pressure of the locking block 17. When the pressure coil 3 and the locking ring 5 finish rotating clockwise, the pressure coil 3 is released, and the locking spring 18 loses pressure and rebounds. This causes the pressure coil 3 to move under the elastic force of the locking spring 18. The protrusion of the pressure coil 3 enters the groove of the locking ring 5, which facilitates the complete engagement and locking of the pressure coil 3 and the locking ring 5, and prevents the pressure coil from becoming loose.

[0024] A limit spring 7 is fixedly installed on one side of the detector body 1, and a limit block 6 is movably connected to one side of the detector body 1. The limit spring 7 and the limit block 6 are movably connected, and the limit block 6 is fixed in cooperation with the pressure coil 3. When it is necessary to change the position of the detector, rotate the pressure coil 3 to release the cooperation with the locking ring 5, drag the pressure coil 3 away from the locking ring 5, and the pressure coil 3 contacts the limit block 6, giving pressure to the limit block 6. The limit block 6 moves downward under pressure, causing the limit spring 7 to contract. When the pressure coil 3 contacts the detector body 1, the protruding part of the limit block 6 enters the slot of the pressure coil 3, the limit spring 7 loses pressure and rebounds, and the protruding part of the limit block 6 moves upward and enters the slot of the pressure coil 3, so that the pressure coil 3 cannot move axially. When it is necessary to rewire, press the limit block 6, and the pressure coil 3 can be pushed again, which helps to prevent the pressure coil 3 from moving randomly when it is not wired.

[0025] A lower contact piece 14 is welded and fixed to one side of the fixed ring 2. Torsion springs 13 are welded and fixed to both sides of the lower contact piece 14. An upper contact piece 12 is welded and fixed to the upper side of the torsion spring 13. When the three wires are inserted into the fixed ring 2, the three wires touch the upper contact piece 12 and squeeze to apply pressure. The torsion spring 13 is deformed by the pressure of the upper contact piece 12, so that the three wires pass through the middle of the upper contact piece 12 and the lower contact piece 14. After the insertion stops, the upper contact piece 12 and the lower contact piece 14 are clamped by the elastic force of the torsion spring 13 to conduct electricity. This makes it easy for the wires of different thicknesses to contact the contact piece to complete the power conduction function.

[0026] A first pressure spring 11 is welded and fixed to both sides of the fixing ring 2, and a second pressure spring 16 is welded and fixed to both sides of the fixing ring 2. The first pressure spring 11 is movably connected to the first pressure shaft 10, and the second pressure spring 16 is movably connected to the second pressure shaft 15. When the first pressure shaft 10 and the second pressure shaft 15 move downward under the pressure of the pressure plate 4, the first pressure spring 11 and the second pressure spring 16 are compressed and contracted. When the pressure coil 3 is disengaged from the locking ring 5, the first pressure shaft 10 and the second pressure shaft 15 lose pressure, and the first pressure spring 11 and the second pressure spring 16 rebound, causing the first pressure shaft 10 and the second pressure shaft 15 to move upward. This allows the first pressure spring 11 and the second pressure spring 16 to play a protective role in preventing the wire from being pinched and broken when the wire is tightened. When the wire is loosened, the first pressure spring 11 and the second pressure spring 16 play a reset role, making it easy to pull out the wire.

[0027] Working principle: Insert the three wires to be connected to the gas detector into the three holes of the fixing ring respectively, and push the pressure coil towards the center of the detector body. During the movement, the pressure coil gradually comes into contact with the pressure plate and exerts downward pressure on the pressure plate. The pressure plate is under force, one side rotates around the rotating shaft, and the other side contracts inward to exert pressure on the three wires inside the fixing ring. When the protruding part of the pressure coil enters the recess of the locking ring, rotate the pressure coil clockwise so that the pressure coil and the locking ring are fully engaged. At this time, the pressure of the pressure coil on the pressure plate is the greatest, so that the three wires inside the fixing ring are completely clamped, which facilitates quick wiring and tightening without the need to tighten each wire individually with a screw, saving time.

[0028] When the pressure plate contracts inward under the pressure of the pressure coil, the return spring contracts under the pressure of the pressure plate. The pressure plate contacts the first and second pressure wire shafts and transmits downward pressure. The first and second pressure wire shafts move inward under the influence of pressure to press the three wires. When it is necessary to change the installation position and pull out the three wires, rotate the pressure coil counterclockwise to release the engagement with the locking ring and push the pressure coil to move in the opposite direction to the center of the detector body. The pressure coil gradually reduces the pressure on the pressure plate, the return spring gradually returns to its original state, and the pressure plate is pushed upward by the elastic force of the return spring. The first and second pressure wire shafts are no longer under downward pressure, and the three wires can be easily pulled out, which facilitates the quick change of the gas detector position.

[0029] When the pressure coil and the locking ring are engaged, the locking block moves inward into the locking ring under the pressure of the pressure coil, and the locking spring contracts under the pressure of the locking block. When the pressure coil and the locking ring finish rotating clockwise, the pressure coil is released, the locking spring loses pressure and rebounds, causing the pressure coil to move under the elastic force of the locking spring. The protrusion of the pressure coil enters the groove of the locking ring, which facilitates the complete engagement and locking of the pressure coil and the locking ring, and prevents the pressure coil from becoming loose.

[0030] When the detector position needs to be changed, rotate the pressure coil to disengage it from the locking ring, drag the pressure coil away from the locking ring, and the pressure coil will contact the limit block, applying pressure to the limit block. The limit block moves downward under pressure, causing the limit spring to contract. When the pressure coil contacts the detector body, the protruding part of the limit block enters the slot of the pressure coil, the limit spring loses pressure and rebounds, and the protruding part of the limit block moves upward and enters the slot of the pressure coil, preventing the pressure coil from moving axially. When rewiring is required, press the limit block, and the pressure coil can be pushed again, which helps to prevent the pressure coil from moving arbitrarily when not connected.

[0031] When the three wires are inserted into the fixed ring, they touch the upper contact plate and are squeezed to apply pressure. The torsion spring is deformed by the pressure of the upper contact plate, so that the three wires pass through the middle of the upper and lower contact plates. After the insertion stops, the upper and lower contact plates are clamped by the spring force of the torsion spring to conduct electricity. This makes it easy for the wires of different thicknesses to make contact with the contact plates to complete the power conduction function.

[0032] When the pressure plates press down on the wire pressing shafts, the pressure springs compress and contract. When the wire pressing coil disengages from the locking ring, the pressure plates lose pressure, and the springs rebound, causing them to move upward. This allows the pressure springs to protect the wire from being snapped when pressing it, and to reset the wire when releasing it, making it easier to pull out the wire.
