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, a type of position switch, is a commonly used low-current master control device. It utilizes the impact of mechanical moving parts to activate its contacts, connecting or disconnecting a control circuit to achieve a specific control objective. Typically, this type of switch is used to limit the position or travel of a machine, enabling it to automatically stop, reverse, change speed, or automatically reciprocate at a specific position or travel.

[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

[0004] (1) Technical problems solved In view of the deficiencies in the prior art, the present invention provides a flameproof and explosion-proof travel switch, which has flameproof and explosion-proof functions and solves the problems in the above-mentioned background technology.

[0005] (2) Technical solution To achieve the above-mentioned purpose, the present invention provides the following technical solution: an 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 interior 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.

[0006] The explosion-proof mechanism comprises: An explosion-proof hard shell, wherein the interior of the explosion-proof hard shell is fixedly connected with a front fixing plate, one side of the front fixing plate is movably connected with a fixing bolt, the outer wall of the fixing bolt is movably connected with a circuit board 1, one side of the circuit board 1 is fixedly connected with a connector, one side of the connector is fixedly connected with a wiring tube, one end of the wiring tube is fixedly connected with a circuit board 2, one side of the circuit board 2 is fixedly connected with a rear fixing plate, and one side of the rear fixing plate is fixedly connected with an external wiring tube, which can make the travel switch safer to use, and the explosion caused by the internal circuit can minimize its impact on the outside, 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.

[0007] Preferably, one end of the external connection 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 gauge, so as to facilitate detection of the voltage of the connection line.

[0008] 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, which can provide people with a high-voltage warning.

[0009] Preferably, one side of the pressure measuring connection plate is fixedly connected to an external interface, and the diameter of the external interface is smaller than the width of the pressure measuring connection plate, allowing current to enter.

[0010] 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.

[0011] Preferably, one side of the flameproof hard shell is fixedly connected to an external connection plate, and the number of the external connection plates is two, providing a fixed connection area for the switch.

[0012] Preferably, one side of the external plate is movably connected with an external bolt and one side of each external plate is provided with an external bolt, so as to facilitate fixing of the switch.

[0013] The present invention provides a flameproof and explosion-proof travel switch. It has the following beneficial effects: 1. This flameproof and explosion-proof limit switch utilizes a flameproof mechanism. Current enters the switch through an external wiring tube, reaching circuit board 2. The current on circuit board 2 then enters the wiring tube, which then transmits the current to the connector and circuit board. If an explosion occurs inside the limit switch, the flameproof hard shell can withstand the explosion, preventing it from affecting external users. This makes the limit switch safer to use, minimizing the external impact of an explosion caused by the internal circuit. This improves the overall safety of the limit switch, reduces the overall risk factor of the limit switch, and enhances the safety of users. This facilitates the long-term use of the limit switch and promotes its widespread use.

[0014] 2. This explosion-proof limit switch utilizes an explosion-proof mechanism. When electricity flows from the external interface, the pressure measuring connection board transmits the incoming current to the pressure measuring device. If the incoming current is too high, a warning light will sound, alerting nearby personnel that the incoming voltage is too high. This achieves explosion-proof protection, improves the overall safety of the limit switch, and adds a hazard prediction function, making it easier for users to clearly understand the current line voltage when using the limit switch, facilitating subsequent response measures.

[0015] 3. The flameproof and explosion-proof travel switch has a fixing mechanism that can fix the external plate to the working position through external bolts, which facilitates the fixation of the travel switch as a whole, so that the travel switch will not be affected by the external environment when in use, thereby improving the stability of the travel switch when in use.
