Description

Technical Field

[0001] The invention relates to the technical field of travel switches, in particular to a flameproof and explosion-proof travel switch. Background Art

[0002] A travel switch is a type of position switch and is a commonly used low-current master control electrical appliance. It uses the collision of the moving parts of the production machinery to make its contacts move to connect or disconnect the control circuit and achieve a certain control purpose. Usually, this type of switch is used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse, change speed or automatically reciprocate at a certain position or stroke.

[0003] However, the travel switches currently available on the market are not very safe to use and cannot provide explosion-proof and explosion-proof functions for the travel switches, which increases the risk factor when using the travel switches and reduces the safety of people when using the travel switches. It is not conducive to the long-term use of the travel switches and is not conducive to the widespread use of the travel switches. Summary of the invention

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an explosion-proof type explosion-proof travel switch, comprising an explosion-proof mechanism, one side of the explosion-proof mechanism is fixedly connected to the explosion-proof mechanism, the inside of the explosion mechanism is fixedly connected to a connecting switch, and one side of the explosion-proof mechanism is fixedly connected to a fixing mechanism.

[0008] The explosion-proof mechanism comprises:

[0009] An explosion-proof hard shell, wherein a front fixing plate is fixedly connected to the inside of the explosion-proof hard shell, a fixing bolt is movably connected to one side of the front fixing plate, a circuit board 1 is movably connected to the outer wall of the fixing bolt, a wiring connector is fixedly connected to one side of the circuit board 1, a wiring capillary is fixedly connected to one side of the wiring connector, one end of the wiring capillary is fixedly connected to circuit board 2, a rear fixing plate is fixedly connected to one side of the circuit board 2, and an external wiring capillary is fixedly connected to one side of the rear fixing plate, so that the travel switch can be safer to use, the explosion caused by the internal circuit can reduce its impact on the outside to a minimum, thereby improving the overall safety of the travel switch, reducing the overall risk factor of the travel switch, improving the safety of users, and being conducive to the long-term use of the travel switch and the widespread use of the travel switch.

[0010] Preferably, one end of the external wiring tube is fixedly connected to a pressure measuring connection plate, and one side of the pressure measuring connection plate is fixedly connected to a pressure measuring device, so as to detect the voltage of the connecting line.

[0011] Preferably, a warning light is fixedly connected to the top of the manometer, and the warning light is located at the top center of the manometer, so as to provide people with a high-voltage warning.

[0012] Preferably, one side of the pressure measuring connection plate is fixedly connected with an external interface, and the diameter of the external interface is smaller than the width of the pressure measuring connection plate, so that current can enter.

[0013] Preferably, the connecting switch is fixedly connected to one side of the circuit board, and one end of the connecting switch is located outside the flameproof hard shell, providing a switch for people's use.

[0014] Preferably, one side of the flameproof hard shell is fixedly connected with an external connection plate, and the number of the external connection plates is two, providing a fixed connection area for the switch.

[0015] Preferably, one side of the external connection plate is movably connected with an external connection bolt and one side of each external connection plate is provided with an external connection bolt, so as to facilitate fixing of the switch.

[0016] The present invention provides a flameproof and explosion-proof travel switch. It has the following beneficial effects:

[0017] 1. The flameproof type explosion-proof travel switch, through the flameproof mechanism, the current enters the switch through the external wiring tube, and then reaches the circuit board 2. The current on the circuit board 2 enters the wiring tube, and the wiring tube sends the current to the connector and the circuit board. At this time, if there is an explosion inside the travel switch, the flameproof hard shell can withstand the explosion, so that it does not affect the external users. The travel switch can be made safer to use, and the explosion caused by the internal circuit can reduce its impact on the outside to the minimum, which improves the overall safety of the travel switch, reduces the overall risk factor of the travel switch, improves the safety of the users, is conducive to the long-term use of the travel switch, and is conducive to the widespread use of the travel switch.

[0018] 2. The explosion-proof travel switch has an explosion-proof mechanism. When electricity flows in from the external interface, the pressure measuring connection board will transmit the incoming current to the pressure measuring device. If the incoming current is too large, the warning light will sound. This will serve as a warning to people around, warning them that the incoming voltage is too high. This will achieve an explosion-proof effect, improve the overall safety of the travel switch, increase the function of predicting danger, and make it easier for people to know the current line voltage when using the travel switch, so as to facilitate subsequent countermeasures for the travel switch.

[0019] 3. The flameproof and explosion-proof travel switch can fix the external plate to the working position through the external bolts through the setting fixing mechanism, which is convenient for fixing the travel switch as a whole, so that the hardness of the position of the travel switch will not be caused by the external environment when in use, thereby improving the stability of the travel switch when in use.
