Abstract
The utility model relates to a fusion alarm of a fuse, in particular to a fusion alarm which is used for a fuse with knife-shaped switch contacts, comprising an under frame that is provided with a microswitch and an L-shaped lever. The microswitch is provided with a button which controls the switching of a switching circuit. The corner of the lever is articulated with the under frame and one end of the lever is contacted with the button of the microswitch while the other end of the level is linked with the fusion action of the fuse. The fusion alarm of the utility model is characterized by quick strain capacity, convenient installation, low manufacturing cost, durability, reliable performance, relatively wide application range and convenient connection, etc., and solves the problems of slow strain capacity, inconvenient installation, higher manufacturing cost, short service life, relatively high probability of wrong action, unreliable performance, being affected by the size of a fused mass, relatively narrow application range and inconvenient connection, etc. existing in the prior art.
Description
Technical field
The utility model relates to a kind of fuse blows alarm, particularly a kind of fuse alarm that is used for chopper switch contact fuse.
Technical background
Existing fuse alarm mainly by fusing impacting body, sensitive switch and, the base three of supporting fusing impacting body and sensitive switch to use partly forms, fuse alarm generally is connected in parallel under the fuse-link two end cover plate hold-down screw, when fuse-link fuses, and then the fusing impacting body moves, eject striker, promote sensitive switch, send signal or automatic switch-over circuit.But existing fuse alarm exists adaptability to changes slow, installs inconveniently, and manufacturing cost is higher, be not durable, and the probability of misoperation is higher, and performance is unreliable, is subjected to the size impact of melt, and range of application is less, problems such as wiring inconvenience.
Summary of the invention
The utility model purpose is to provide a kind of adaptability to changes fast, easy for installation, low cost of manufacture, durable, dependable performance, range of application is wider, the fuse blows alarm of easy-to-connect, the adaptability to changes that has solved the prior art existence is slow, easy for installation, manufacturing cost is higher, be not durable, and the probability of misoperation is higher, performance is unreliable, be subjected to the size impact of melt, range of application is less, problems such as wiring inconvenience.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise underframe, described underframe is provided with sensitive switch and L shaped lever, described sensitive switch is provided with the button that the control switch circuit opens and closes, lever corner and underframe are hinged, described lever one end touches mutually with the button of sensitive switch, and the other end is related with the fusing of fuse.Adopt L shaped lever can shorten the length dimension of lever on the one hand, thereby make structure of the present utility model more compact, be convenient to install; Another convenient L shaped lever has shortened the respective distance of microswitch push-button to the fuse blows action, also improved the respond of sensitive switch to the fuse blows action, improved adaptability to changes of the present utility model, reduced misoperation, made that performance of the present utility model is more reliable.
As preferably, described lever and fuse blows action associated end are provided with push rod, and the push rod end is provided with the push rod face, and the described push rod face back side is provided with the indenture that disjunction is convenient in some roads.Complete push rod face can satisfy the cooperation needs of the fuse of large-size, when the size of fuse hour, can remove unnecessary push rod face by the indenture place, dwindle the push rod face, thereby make the utility model can satisfy the fuse of multiple different model, enlarge range of application of the present utility model.
As preferably, described underframe is provided with a thickening part, described thickening part form one with the bearing-surface of joint, lever side.Supporting surface can limit lever makes lever support toward a direction motion, thereby makes that performance of the present utility model is more reliable.
As preferably, side, described thickening part forms a groove, forms a thin-walled between groove and the bearing-surface, is installed with an elastic limit part in the described groove, and described elastic limit part has the elastic portion of a resiliency supported at described thin-walled inner face.Wherein, the thickening part is provided with groove one conveniently can alleviate overall weight of the present utility model, so that install; Another convenient also convenient with limited part is set within it, and limited part can limit the support of maintenance to thin-walled, thereby makes bearing-surface to the resiliency supported of lever side, to improve damping performance of the present utility model, to prolong useful life of the present utility model.
As preferably, be connected by tapping screw between described lever and underframe, described tapping screw is screwed in the lever after the underframe end passes, and makes lever can be neatly rotate in confined range of movement at the interface point around itself and underframe on the underframe.
Therefore, it is fast, easy for installation to the utlity model has adaptability to changes, low cost of manufacture, durable, and dependable performance, range of application is wider, characteristics such as easy-to-connect.
