Description
Technical field
The utility model belongs to power assist device technical field, is specifically related to a kind of air switch quick replacement device.
Background technology
Air switch has another name called air-break, and it is using air as arc-extinguishing medium, as long as be that in a kind of circuit, electric current exceedes the switch that rated current will disconnect automatically.Be applied in ammeter box uses as the master switch of resident more in daily life, and when short circuit current is much larger than normal load electric current, short circuit current causes electrical apparatus release to be threaded off, and moving contact separates with static contact under the action of the spring, and circuit is disconnected.During installation, with the slide rail showing air switch in case for relying on, snapped in by air switch in the dovetail groove of slide rail, due to table case narrow space and wiring is complicated, free-hand being difficult to is in place.Normally, repair personnel is when changing air switch, and translation-angle of having to relies on previous experiences feel to go to operate, and causes the operating time longer, affects operating efficiency.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of air switch quick replacement device, a people can be realized time saving and energy saving, carry out the replacing of air switch safely and reliably, save human resources, improve operating efficiency, effectively evade work risk.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of air switch quick replacement device, comprise handle and knife bar, the rearward end of described handle is spheroid, and the middle part week side of described handle arranges arc groove, the front end of described handle is connected with described knife bar, described knife bar comprises connecting rod and knife and fork, and described connecting rod rear end is connected with described handle, and front end is connected with described knife and fork, described knife and fork has tip, and in yi word pattern opening.
Described groove is at least 2.
The length of described handle is 95 ~ 100 millimeters.
The length of described knife bar is 95 ~ 100 millimeters.
The yi word pattern aperture pitch of described knife and fork is 5 millimeters.
Described handle is silicon rubber product.
Described knife and fork is glass hard steel product.
The beneficial effects of the utility model are as follows: a kind of air switch quick replacement device of the utility model, by the simple combination of handle and knife bar, can realize a people time saving and energy saving, carry out more changing jobs of air switch safely and reliably.Wherein, the middle part week side of described handle arranges arc groove, makes this device have stronger antiskid function, strengthens security performance during operation; Described knife and fork has tip, and in yi word pattern opening, need match with the active open bottom the air switch that will change.
During use, first the side of air switch is snapped in the dovetail groove of slide rail, utilize the tip of knife and fork in the utility model to catch on the active open bottom air switch simultaneously, utilize lever principle to exert oneself laterally, the active open of air switch is snapped in dovetail groove.Like this, 1 people just easily can complete replacing, reduces task difficulty, improves the successful operation rate of staff.
The utility model structure novel, safe and reliable, practical, alleviate the difficulty that operating personnel changes air switch, improve the operating efficiency of operating personnel, effectively evade work risk.
