[0040] Reference Figures 1-4 For the second embodiment of the utility model, the pull rod 201 comprises a straight rod 201a which is sleeved on the inner side of the through slot 101, an arc rod 201b which is protruded on one side of the straight rod 201a, and a connecting block 201c which is arranged on one side of the arc rod 201b.

[0041] Further, the connecting block 201c comprises a straight slot 201c-1 which is arranged through the end face of the connecting block 201c;

[0042] The driving rod 202 comprises a connecting rod 202a slidably connected to the straight slot 201c-1, a rotating shaft 202b arranged on one side of the connecting rod 202a, and an L-shaped rod 202c arranged on the other side of the rotating shaft 202b.

[0043] Further, the connecting rod 202a comprises a protruding column 202a-1 arranged on the end thereof, and the protruding column 202a-1 is slidably connected to the straight slot 201c-1.

[0044] The fixing seat 203 comprises a clamping seat 203a arranged on the end thereof, and the rotating shaft 202b is hingedly connected to the clamping seat 203a.

[0045] Further, the L-shaped rod 202c comprises a circular slot 202c-1 arranged on the end face thereof, and a blocking rod 202c-2 arranged on the inner side of the circular slot 202c-1.

[0046] Further, the closing member 204 comprises a pressing rod 204a slidably sleeved on the inner side of the circular slot 202c-1, and a spring 204b arranged on the peripheral side of the pressing rod 204a.

[0047] Further, the pressing rod 204a comprises a movable slot 204a-1 arranged on the end thereof, and a circular face 204a-2 arranged on the other end thereof.

[0048] The blocking rod 202c-2 is slidably connected to the movable slot 204a-1.

[0049] Further, the fixing seat 203 comprises an arc block 203b arranged on one side of the pressing rod 204a.

[0050] The switch 301 comprises an arc piece 301a fixedly clamped on the inner side of the fixing seat 203, and a connecting piece 301b arranged on one side of the arc piece 301a.

[0051] Further, the pressing rod 204a is slidably clamped in the arc block 203b, and the bendable arc piece 301a.

[0052] It should be noted that the straight rod 201a of the pull rod 201 is hingedly connected to the through slot 101 of the gate rod 100 by a plug-in mode, the arc rod 201b extending on one side of the straight rod 201a extends the entire rod body inward, facilitating connection to the driving rod 202. The arc rod 201b changes the direction of the pull rod 201, and the connecting block 201c is fixedly connected to the tail of the arc rod 201b. The connecting block 201c is specially shaped, and is L-shaped as a whole, and a straight slot 201c-1 is formed through the rod body of the connecting block 201c, which is horizontally arranged on the connecting block 201c and connected to the slot of the driving rod 202.

[0053] Preferably, one side of the driving rod 202 is a connecting rod 202a, and the end of the connecting rod 202a is provided with a protruding column 202a-1 which is slidingly connected in the straight slot 201c-1. The fixed seat 203 is fixedly connected in the inside of the electric meter box 400 by clamping, and a group of clamping seats 203a are provided in the eaves of the fixed seat 203, which are half-round grooves, so as to clamp the rotating shaft 202b in the middle part of the driving rod 202 in the clamping seat 203a. The driving rod 202 is fixed in the specified position.

[0054] Preferably, the connecting block 201c has a large weight, so that it can keep the horizontal state of the straight slot 201c-1 under the limitation of the protruding column 202a-1, and the driving rod 202 can rotate under the limitation of the clamping seat 203a.

[0055] Preferably, the other side of the driving rod 202 is an L-shaped rod 202c, the end of the long rod part is fixedly connected to the rotating shaft 202b, and the shorter side is provided with a round groove 202c-1, and the round groove 202c-1 is fixedly provided with a stop rod 202c-2. The round groove 202c-1 provides space for the movement of the pressing rod 204a in the closed part 204. The end of the pressing rod 204a is also provided with a movable groove 204a-1. The stop rod 202c-2 is slidingly connected in the movable groove 204a-1, thereby limiting the radial rotation of the pressing rod 204a, so that the circular surface 204a-2 at the bottom of the pressing rod 204a always abuts against the arc block 203b on the fixed seat 203.

[0056] Preferably, a group of springs 204b are sleeved on the side of the pressing rod 204a, one side of the spring 204b abuts against the convex surface of the circular surface 204a-2 of the pressing rod 204a, and the other side of the spring 204b abuts against the back of the L-shaped rod 202c. When the driving rod 202 rotates, the L-shaped rod 202c rotates around the rotating shaft 202b, and the circular surface 204a-2 of the pressing rod 204a abuts against the arc block 203b, so that the L-shaped rod 202c and the pressing rod 204a squeeze the springs 204b inside them under the action of rotation. When the pressing rod 204a is in the horizontal state, the springs 204b are compressed to the maximum, and when they move to both sides, the potential energy of the springs 204b is released, which indirectly promotes the reset or tripping of the brake rod 100.

[0057] Preferably, the arc block 203b on the fixed seat 203 is a quarter circular block, and the upper half end thereof is inserted with the arc piece 301a, and the arc piece 301a and the arc block 203b form a semicircular arc, so that the pressure rod 204a can smoothly slide on the semicircular arc formed by the arc piece 301a and the arc block 203b. The arc piece 301a is a copper piece, which, under its own elasticity, moves backward and resets after being extruded by the pressure rod 204a. A set of straight plate-shaped connecting pieces 301b are also inserted on the adjacent side of the fixed seat 203, and the connecting pieces 301b are also copper pieces. The connecting pieces 301b and the arc piece 301a are not connected in the natural state, that is, the loudspeaker 302 will not produce sound. When the arc piece 301a is extruded, the arc piece 301a moves backward and presses on the connecting piece 301b, so that the connecting piece 301b and the arc piece 301a are in contact, and the loudspeaker 302 is powered on to produce sound.

[0058] In the normal working state, the gate lever 100 remains in the closed position and is located above. At this time, the pull rod 201 is maintained in the relatively upper position under the limiting action of the protruding column 202a-1 on the connecting rod 202a on one side thereof; and the L-shaped rod 202c on the other side of the drive rod 202 is located below the connecting rod 202a. This configuration ensures that the pressure rod 204a behind the L-shaped rod 202c abuts against the bottom of the arc block 203b and does not contact the arc piece 301a. Therefore, in this natural state, there is no electrical connection between the connecting piece 301b and the arc piece 301a, and the loudspeaker 302 will not be powered on to activate and remain silent.

[0059] When an abnormal situation occurs in the circuit, the gate lever 100 will automatically trip and trigger the drive rod 202 to rotate. Specifically, the pull rod 201 will move under the action of the through slot 101 and drive the protruding column 202a-1 downward through the straight slot 201c-1 on the connecting block 201c. With the downward movement of the protruding column 202a-1, the drive rod 202 will rotate, so that the L-shaped rod 202c on the other side thereof moves upward to above the connecting rod 202a. In this process, the pressure rod 204a at the lower end of the L-shaped rod 202c slides along the arc block 203b and compresses the spring 204b. Finally, when the circular surface 204a-2 of the pressure rod 204a is separated from the arc block 203b and contacts the arc piece 301a, the compressed spring 204b releases energy, pushes the arc piece 301a to deform and move backward, and presses the connecting piece 301b. This action establishes an electrical connection between the connecting piece 301b and the arc piece 301a, causes the loudspeaker 302 to be powered on, and emits an alarm sound to remind the user that the air switch has tripped and needs to be checked and reset.

[0060] In summary, the device realizes the function of automatically triggering an alarm when the air switch is tripped due to circuit abnormalities by the setting of the connecting unit 200. When the trip lever 100 detects abnormal conditions such as circuit overload or short circuit and is tripped, the pull rod 201 moves and drives the convex column 202a-1 on the drive rod 202 to move down through the straight slot 201c-1, thereby promoting the rotation of the drive rod 202. Not only does it make the L-shaped rod 202c move upward, but also makes the pressure rod 204a slide along the arc block 203b and compress the spring 204b. Finally, when the pressure rod 204a is separated from the arc block 203b and contacts the arc piece 301a, the spring 204b releases energy to push the arc piece 301a to deform and move backward, compressing the connecting piece 301b, establishing an electrical connection, and making the horn 302 electrified to sound an alarm. By using the mechanical structure and spring return mechanism, the normal operation of the alarm system can be ensured even in the case of power failure, enhancing the reliability and stability of the system.

[0061] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
