Description

Technical Field

[0001] The utility model relates to an air switch, in particular to an air switch which can prevent accidental touching. Background Art

[0002] An air switch, also known as a circuit breaker or air circuit breaker, is a switching device used to protect electrical circuits from overload, short circuit and other faults. Its working principle is to determine whether it is necessary to cut off the power supply by detecting changes in current to protect other components in the circuit from damage.

[0003] However, the existing air switch does not have a reminder function. When a staff member is operating the circuit in the open state, if the air switch is turned on by other personnel, the staff member will operate in the closed state, which poses a major safety hazard. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-accidental-touch air switch with a reminder function, which can reduce safety hazards.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an anti-accidental touch air switch, comprising: a body, a handle, a gear lever and two elastic mechanisms;

[0006] The handle is set on the main body, and the handle controls opening or closing of the switch, and a card slot is set on the handle;

[0007] The two elastic mechanisms are symmetrically arranged on both sides of the main body, the gear lever corresponds to the card slot, and the two ends of the gear lever are respectively arranged on the main body through the elastic mechanism. The elastic mechanism includes a shell, a spring and a connecting rod. The shell is arranged on the side of the main body, and the spring is located in the shell. One end of the spring is connected to the shell, the first end of the connecting rod passes through the shell and is connected to the other end of the spring, and the second end of the connecting rod is connected to the end of the gear lever.

[0008] Furthermore, the elastic mechanism also includes a connecting block, which is located in the shell. The two ends of the spring are respectively connected to the shell and the connecting block. A through slot is provided on the shell, and the connecting block passes through the through slot and is connected to the first end of the connecting rod.

[0009] Furthermore, the elastic mechanism also includes a rotating shaft, one end of which is connected to the connecting block, and the other end of the rotating shaft passes through the through slot and is hinged to the first end of the connecting rod.

[0010] Furthermore, the elastic mechanism also includes a guide rod, the guide rod is located in the shell, the spring is sleeved on the guide rod, and the connecting block is arranged through the guide rod.

[0011] Furthermore, it also includes a handle mechanism, which is connected to the gear lever.

[0012] Furthermore, the handle mechanism includes a pull rod and two movable rods, the two movable rods are respectively located at the two ends of the gear rod, the movable rod is located between the handle and the connecting rod, one end of the movable rod is hinged to the gear rod, and the other end of the movable rod is connected to the pull rod, and the pull rod is parallel to the gear rod.

[0013] The beneficial effects of the utility model are:

[0014] The utility model has a simple structure. When the staff is operating the circuit in the open state, the lever is locked in the slot, which means that the staff is currently operating the circuit and cannot open the switch. If the staff is in the open state and the lever and the slot are not locked, it means that the power is automatically cut off and the staff is not operating the circuit, so the switch can be opened. The utility model is provided with a lever and a slot, which makes it easy to distinguish whether the open state is operated by the staff or automatically cut off, which is conducive to the staff to safely operate the circuit, realizes the anti-accidental touch function and reduces safety hazards.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1-4 As shown, an anti-accidental-touch air switch includes a body 1, a handle 2, a gear lever 3, a handle mechanism 4, and two elastic mechanisms 5.

[0024] The main body 1 is an air switch main body 1, which is a prior art. The handle 2 is used to close or open the switch. The handle 2 is arranged on the main body 1. The connection relationship between the handle 2 and the main body 1 is a prior art. A slot 21 is provided on the handle 2.

[0025] Two elastic mechanisms 5 are respectively arranged on both sides of the main body 1, and the two elastic mechanisms 5 are symmetrically arranged. The gear lever 3 is engaged with the card slot 21, and the two ends of the gear lever 3 are respectively arranged on the main body 1 through the elastic mechanism 5. The elastic mechanism 5 includes a shell 51, a guide rod 52, a connecting block 53, a rotating shaft 54, a spring 55 and a connecting rod 56. The shell 51 is arranged on the main body 1, and a through slot is arranged on one side of the shell 51; the guide rod 52 is located in the shell 51; the spring 55 is located in the shell 51 and is sleeved on the guide rod 52, and one end of the spring 55 is connected to the shell 51; the connecting block 53 is located in the shell 51, and the connecting block 53 is sleeved on the guide rod 52; one end of the rotating shaft 54 ​​is connected to the connecting block 53, and the other end of the rotating shaft 54 ​​passes through the through slot and is hinged to the first end of the connecting rod 56, and the second end of the connecting rod 56 is connected to the end of the gear lever 3.

[0026] The handle mechanism 4 is connected to the gear lever 3. The handle mechanism 4 includes a pull rod 41 and two movable rods 42. The two movable rods 42 are respectively arranged at the two ends of the gear lever 3. The movable rod 42 is located between the connecting rod 56 and the handle 2. One end of the movable rod 42 is hinged to the gear lever 3, and the other end of the movable rod 42 is connected to the pull rod 41.

[0027] In daily use, the lever 3 is set close to the body 1 and does not affect the opening or closing of the handle 2. In this embodiment, when the handle 2 is at the bottom, it is in the opening state. When the staff needs to open the circuit to operate the circuit, they pull the handle 2 down and make the handle 2 Figure 1 As shown, when the pull rod 41 is pulled outward, the pull rod 41 drives the movable rod 42 outward, which in turn drives the shift lever 3 outward. The shift lever 3 drives the connecting rod 56 outward, which drives the rotating shaft 54 ​​to slide outward along the through slot. The rotating shaft 54 ​​drives the connecting block 53 to slide outward, and at the same time, the spring 55 is compressed, placing the shift lever 3 in the slot 21 of the handle 2. The spring 55 always applies elastic force to the connecting block 53. Under the transmission of the rotating shaft 54 ​​and the connecting rod 56, the shift lever 3 is locked in the slot 21. Only when the pull rod 41 is pulled outward and the movable rod 42 and the shift lever 3 are moved, can the shift lever 3 and the slot 21 be engaged. Therefore, when the shift lever 3 is locked in the slot 21, it means that the staff is performing circuit operation and cannot open the switch. When the handle 2 is open and the shift lever 3 is not locked in the slot 21, it means that the main body 1 is automatically open and other personnel can open the switch.

[0028] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
