Description

A kind of warning device of manually pushing

Technical field

The utility model relates to warning device, relates in particular to a kind of warning device that manually pressure-locks and pass through the key release.

Background technology

The existing warning device that is used for fire-fighting or others can not reset after pushing warning in locking, just need be with just resetting after the key release, but existing warning device latch-up structure more complicated, make cost of products higher, also inconvenient during release, therefore, how to realize that warning device the locking and unlocking is convenient and simple in structure, cost is low is a technical matters that needs to be resolved hurrily in the industry.

The utility model content

The utility model is for solving above-mentioned technical matters, provides a kind of simple in structure, the locking and unlocking manually to push warning device easily.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of warning device of manually pushing, comprise the shell that constitutes by panel and base plate, warning pressing board in this shell, alarm module by this its circuit of warning pressing board conducting, lock and remove the locking device of this warning pressing board, wherein, described locking device comprises and being separately positioned on described warning pressing board and the described alarm module and adaptive pair of catches mutually, on described shell, be provided with and insert the keyhole of key described pair of catches release, at least one cover provides the elastic force apparatus of reseting elasticity for described warning pressing board; Described elastic force apparatus comprises the spring suppport, the spring bearer plate that are fixed on the described base plate, support arm and spring reset, this spring suppport flexibly connects by a middle part with this support arm that resets of its setting, one end of this support arm that resets flexibly connects by slotted hole and this spring bearer plate of its setting, the projection that is provided with on its other end and the described warning pressing board contacts, and this spring is arranged between this spring suppport and this spring bearer plate.

Wherein, described warning pressing board limit flexibly connects by the axis hole that is provided with on stationary shaft and the described alarm module.

Preferred embodiment, described elastic force apparatus are two covers and are separately positioned on two angles of described warning pressing board.

Compared with prior art, the utility model provides reseting elasticity for the warning pressing board by elastic force apparatus, the warning pressing board is pressed after the locking, as long as pair of catches suitable on warning pressing board and the alarm module is separated (being release) by key, the warning pressing board will reset at once under the effect of elastic force apparatus, and the present invention is simple in structure, and cost is lower, easy to operate, do not need other unnecessary action during release.

Embodiment

The utility model preferred embodiments, as Fig. 5 a, shown in Fig. 6 a, a kind of warning device when manually pushing, comprise the shell that constitutes by panel 1 and base plate 2, warning pressing board 3 in this shell, alarm module 4 by this its circuit of warning pressing board conducting, lock and remove the locking device of this warning pressing board, as Fig. 4 b, shown in Fig. 5 b, this locking device comprises and being separately positioned on warning pressing board 3 and the alarm module 4 and adaptive pair of catches 31 mutually, 41, on shell, be provided with and insert key 6 and pair of catches 31, the keyhole of 41 releases, two covers provide the elastic force apparatus 5 of reseting elasticity for warning pressing board 3, as Fig. 5 c, shown in Fig. 5 d, this elastic force apparatus 5 comprises the spring suppport 51 that is fixed on the base plate 2, spring bearer plate 52, support arm 53 and spring 54 reset, this spring suppport flexibly connects by one 511 axis hole that is provided with these support arm 53 middle parts that reset of its setting, the axle that is provided with on the slotted hole 531 of one end of this support arm that resets by its setting and this spring bearer plate 52 flexibly connects, the projection 32 that is provided with on the other end of this support arm that resets and the warning pressing board 3 contacts, moved by projection 32 support arm 53 1 ends that promote to reset, this spring is arranged between spring suppport and the spring bearer plate.Two cover elastic force apparatus 5 are separately positioned on two angles of warning pressing board 3, feasible more balance.A limit of warning pressing board 3 flexibly connects by the axis hole 42 that is provided with on stationary shaft 33 and the alarm module 4.

When running into the emergency call use, pressing position on the warning pressing board 3 34 is pressed backward, warning pressing board 3 will move backward around stationary shaft 33, Fig. 5 c is the state when not reporting to the police, state when Fig. 5 d is warning, thereby the circuit that makes alarm module 4 is connected and is reported to the police, in case warning circuit is connected, a pair of adaptive snap close 31 mutually, 41 will interlock locking can not untie automatically, when wanting release, need insert by keyhole and with the snap close 31 that fastens with the key 6 of special use, 41 separately, because when pushing warning pressing board 3, warning pressing board 3 makes the spring of elastic force apparatus 5 be in the energy storage state by its projection 32, in case snap close 31,41 separately, warning pressing board 3 release that resets under the effect of spring force, warning circuit disconnects and makes alarm release at once.

Abovely the utility model is specifically described, but those skilled in the art can make numerous variations or variation to these embodiments these changes and changing within the scope that should fall into the utility model protection in conjunction with better embodiment.
