Description

Technical Field

[0001] The utility model relates to the technical field of protective structures, in particular to an air switch protective structure. Background Art

[0002] An air switch is a circuit breaker that automatically disconnects the circuit when the current in the circuit exceeds the rated current. An air switch, also known as an air circuit breaker, is a very important electrical appliance in low-voltage power distribution networks and electric traction systems. It combines control functions with multiple protection functions, such as overload protection and short-circuit protection. When an overload or short circuit occurs in the circuit, the air switch will automatically trip and disconnect the circuit to protect the wires and equipment from damage. Air switches are widely used in low-voltage electrical appliances and distribution boxes, using air to isolate the moving and static contacts to ensure the safe operation of the circuit. When choosing a household air switch, it is necessary to consider factors such as power consumption, power, and protection to ensure that the appropriate model and specification of the air switch is selected. The air switch is different from the leakage protector, which is mainly used to prevent leakage and human electric shock, while the air switch is mainly used to prevent the circuit from overloading. In addition, a circuit breaker is an air switch that can carry and disconnect normal and abnormal circuits.

[0003] Since the air switch is connected to the power system, in order to avoid leakage and other phenomena, a protective cover is generally used to shield the air switch from the outside;

[0004] Existing air switches generally have a fixing frame that is buckled onto the upper side of the air switch and then fixedly connected by screws. However, when subjected to external impact, the vibration of the fixing frame will still cause failure or damage to the air switch, and the fixed installation method is not convenient for subsequent operation and maintenance of the air switch.

[0029] The lower end of the fixing frame 3 is clamped by the clamping structure 4 so that it can abut against the mounting plate 2, and the clamping structure 4 facilitates the opening and closing of the fixing frame 3, bringing convenience to subsequent operation and maintenance work. When subjected to external impact, the impact is mitigated by the fixing cover 5 in conjunction with the supporting structure and the rubber pad 35, thereby effectively protecting the switch body 1.

[0030] In another embodiment, see Figures 1 to 4 The clamping structure 4 includes a movable block 41 perpendicular to the mounting plate 2, the bottom of the movable block 41 is slidably arranged on the mounting plate 2, a limit slot 21 is longitudinally provided on the mounting plate 2 corresponding to the movable block 41, a limit slider 43 slidably connected to the limit slot 21 is provided at the bottom of the movable block 41 corresponding to the limit slot 21, a first spring 44 is further provided in the limit slot 21, the first spring 44 is located on the upper side of the limit slider 43, a clamping block 42 is provided on the lower side of the top of the movable block 41, a clamping plate 32 is horizontally provided between the two protective blocks 31 at the bottom of the clamping block 42, and the clamping block 42 can be clamped with the clamping plate 32;
