The specific embodiment

Below, also in conjunction with the accompanying drawings the utility model is described in further detail by specific embodiment.

As shown in Figure 1, be depicted as and a kind ofly reset and the indirect manual fire alarm call point of inserting mode, comprising: telephone jack 1 with specific purpose tool, loam cake 2, back-moving spring 3, clear switch 4, button 5, capping 6, base 7, binding post 8, the pin 9 that resets connects capping and loam cake screw 10, last contact chip 11, following contact flat spring 12, terminal screw 13, pre-buried wiring nut 14, pcb board 15.

Described loam cake 2 is rotatably connected for activity with button 5, but the groove 24 of a press fit is set on loam cake 2, rotatable in two column rotating shaft 27 card entry slots with the button side, back-moving spring 3 is installed in the circular mounting groove 26 of button 5, the chucking difficult drop-off.

Last contact chip 11 is for being barb extruding chucking installation automatically, its barb position 43 is up spacing during press fit at last contact chip 11, is moving to terminal point, when last contact chip 11 is in place, block tongue 42 since elasticity be used to contact chip be tightened do not come off in the draw-in groove 34 that power springs into capping 6.Simultaneously, insert in the welding hole of pcb board 15 reservations at the semicircle position 41 of last contact chip 11 heads, getting in touch of conducting and wiring board, the clear switch 4 with self-locking then is not welded on the pcb board 15, and its pairing position is can obtain on the appropriate location of clear switch 4 conductings after assembling.Last contact chip 11 also can be assemblied in the capping by fixed terminal 40, can directly insert capping place again with welding with pcb board together with the fixed terminal of going up contact chip.

Capping after assembling such as Fig. 1 a need with four screws 10 that are installed on the loam cake 2 fixing, built-up circuit and button actions part.Press push button 5, promptly driving clear switch 4 presses down and is in conducting state, release button 5 after being depressed into preposition, under the effect of back-moving spring 3, will make its resilience, this moment, the head of button 5 was the bottom with certain flexible spacing buckle 32 that trapezoidal boss 25 will be stuck in capping 6, and this position guarantees that button is in conducting state and transfers out signal to circuit part.When it was resetted, the pin 9 that resets inserted the alarm button side, and loam cake 2 cooperated the guide-track groove 23 that resets that forms with base 7 in, the pin 9 that resets was the rectangular shaped 28 of coincideing mutually with guide rail.After the insertion, flat and the oblique intermediate location 20 of pin 9 heads resets, aligned position is head 39 places of the spacing buckle of capping 6, utilize the power of inserting inward, the rail sections 21 fixing non-migrations that form by the pin 9 that resets, back down spacing buckle in the capping 6 with head intermediate location 20, the insertion stroke of pin 9 is spacing by the volume part 22 of afterbody when the excess of stroke, button 5 is owing to lose spacing control simultaneously, under the effect of back-moving spring 3, upspringing returns on the medial surface that is adjacent to loam cake 2, reaches the effect that conveniently resets.

Following contact chip 12 is fixed on the base by binding post 8, becomes the left and right sides to arrange, and connects pilot and divides two row's inlet wires from the base entrance hole, receives respectively on the corresponding base contact flat spring.Insert in the square groove 30 of binding post 8 front ends at 12 liang of rounding positions of following contact chip 45, shell fragment head 46 inserts in the draw-in groove 29 of binding post 8 rear ends simultaneously, after the insertion, 44 at the Elastic Contact position of shell fragment returns to free state, once be stuck in 37 places, front of terminal, binding post 8 utilizes four self threading pins 16 that are fixed on the base 7 to be locked.

The base portion that assembles such as Fig. 5, in when construction, after being fixed on the wall, the connection pilot of introducing from base entrance hole 38 directly is connected on the fixing following contact flat spring 12 of binding post 8, adopt normal tape grommet screw 13 and embedded nut to tighten, connect fire alarm control system.Circuit and button actions partly are an independently integral body, rely on the button bit that assumes diamond in shape 31 of projection in the capping 6, press down in the process in assembling, and with Elastic buckle 36 Elastic Contact that present bending shape on the base 7, elastic stability is not drawn out easily.Simultaneously, be assemblied in the capping 6 last contact chip 11 be assemblied in following contact chip 12 on the base binding post 8 also owing to press down displacement, the back side 47 of contact flat spring is just in time pushed up at the elasticity position 44 of following contact chip 12, is conducting state.Thus, moving pcb board 15 from clear switch 4 has formed the system of a conducting, thereby has made split type mediate contact mode reach the effect of stable transfer alarm button signal again to connecting pilot to following contact chip 12 again to last contact chip 11 again.Under normal condition, the pin 9 that resets is deposited by the administration of the prevention and control owner, is common to the utility model, and the back insertion of reporting to the police can reset.Take away circuit and button actions part, need common straight screwdriver and alarm button side open hole to exert oneself slightly to rotate and can open, directly insert the maintenance back, promptly is in normal operating conditions.

When normal condition, alarm host machine has two lines to insert on the connecting terminal block of hands newspaper (specifically which terminal is determined according to each different producer's designing requirement), when the button of hand newspaper is not pressed, the utility model is in normal monitor state, just the contact of touch-switch is in off-state, the signal of alarm host machine reception simultaneously is normal monitored address coded signal, after button is pressed, the closing of contact of touch-switch, the hand newspaper produces an alarm signal and gives alarm host machine through two bus transfer, in a single day alarm host machine gathers alarm signal and the address signal that newspaper in one's hands sends, alarm host machine is sent the alarm signal of sound and light at once and is reminded the manual pull station of this address of operator on duty to be pressed, and fire has taken place in this zone.
