Embodiment
Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.
Fig. 1 is extremely shown in Figure 3 to be the structural representation of the utility model.
Reference numeral wherein is: shell block body 1, loam cake 2, arcwall face 2a, indent district 21, tapering face 21a, bottom surface 21b, guide through hole 22, correcting slide opening 23, circular periphery 24, manual button 3, key plate 31, taper surface 31a, curved surface 31b, switch triggering guide rod 32, anticreep location slide fastener 33, slide bar 331, stopping discount 332, back-moving spring 4, groove 5, bar groove 6.
Extremely shown in Figure 3 like Fig. 1; The smoke alarm with key switching structure of the utility model; Be provided with the shell block body 1 of induction alarm circuit and the loam cake 2 equipped mutually in comprising with shell block body 1; The upper surface center of being shaped on of its loam cake 2 has the indent district 21 of guide through hole 22, and the first-class radian of bottom surface 21b in indent district 21 is uniformly distributed with and is shaped on correcting slide opening 23, is equipped with in the indent district 21 and pushes the manual button 3 that triggers the induction alarm circuit; Manually button 3 is shaped on the switch triggering guide rod 32 and anticreep location slide fastener 33 that matches with guide through hole 22 and correcting slide opening 23 respectively; Switch triggering guide rod 32 is set with back-moving spring 4, an end of back-moving spring 4 and the surperficial apical grafting mutually of key plate 31 lower plates of manual button 3, and the other end matches with the bottom surface 21b roof pressure in indent district 21.Compare with conventional art; The utility model increases at the middle part of loam cake 2 and is shaped on indent district 21; And in indent district 21, be fitted with the manual button 3 of manually pushing triggering internal alarm circuit, manually button 3 reaches through switch triggering guide rod 32 turning circuits that move downward together and triggers the purpose of reporting to the police.Correcting slide opening 23 matches with anticreep location slide fastener 33, can guarantee that manual button 3 can not take place circumferentially to rotate and cause the bias voltage phenomenon, and it is more steady that manual button 3 is moved in the process of pressing down.Anticreep location slide fastener 33 also has a vital role, and when under the effect of back-moving spring 4, making manual button 3 recover virgin state exactly, anticreep location slide fastener 33 can guarantee that manual button 3 can not break away from loam cake 2.The utility model has been expanded the utility function of alarm, not only makes this product when causing sensitivity decline or dangerous situation smokescope low owing to other factors, after it is found that; Can trigger through manual button 3 and implement manually to report to the police; Simultaneously can also be after installation, under long-range circumstances, carry out the detection alarm test confirming the validity of alarm, can timely discovery have damaged or the product of loss of function through testing; So that advanced processing or replacing guarantee the security of warning system.The utility model is simple in structure, and good looking appearance is easy to install, and volume is little, occupies little space, and it is low to have a production cost, the characteristics that function is practical.
Be further to optimize properties of product, improve the market competitiveness, as shown in Figure 2 among the embodiment, loam cake 2 is for to have the circular lid that extends below circular periphery 24, and the upper surface of loam cake 2 and 21 arrangements of indent district are shaped on the groove 5 that is connected and makes things convenient for air flow.Groove 5 not only helps the transfer of vibration of air or catching of extraneous air information, also makes this product mouth look attractive in appearance more beautiful simultaneously.
Among the embodiment, the upper surface of loam cake 2 is the arcwall face 2a of evagination, and indent district 21 is circular recessed district, and the side face in indent district 21 is the tapering face 21a that has the inclination cone angle.The upper surface of loam cake 2 is changed original planar structure, adopts arcuate structure, makes the stereoscopic sensation of this product stronger, and form is more beautiful.Indent district 21 can adopt other shape, and the utility model is in order to make integral uniform property good, and circular structure is preferably done in indent district 21, and circular structure meets people's esthetic requirement.
From Fig. 2, Fig. 3, can find out; Manually the key plate 31 of button 3 is the circular lamellar body suitable with indent district 21; The periphery of key plate 31 is shaped on the taper surface 31a that matches with tapering face 21a, and switch triggering guide rod 32 is connected on the lower plate surface of spill on the key plate 31 with anticreep location slide fastener 33.Key plate 31, switch triggering guide rod 32 and anticreep location slide fastener 33 are a single piece, and have constituted manual button 3 together.Under original state because the effect of back-moving spring 4 makes the distance that maintains compression movement between the bottom surface 21b in key plate 31 and indent district 21; In order to prevent that dust from getting into and it is light flexibly to guarantee that manual button 3 is pushed; The periphery of key plate 31 is shaped on the taper surface 31a that matches with tapering face 21a shape, leaves the movement clearance of annular between same taper surface 31a and tapering face 21a.
Among the embodiment, guide through hole 22 is a circular port, and switch triggering guide rod 32 is the cylindrical body of hollow, and switch triggering guide rod 32 slides and is located in the guide through hole 22.
The anticreep of the utility model location slide fastener 33 comprise the slide bar 331 that can slide up and down along correcting slide opening 23 and with the interlock stopping discount 332 of anticreep of correcting slide opening 23 lower edge oral thermometer faces, the outward extending convexity of stopping discount 332 for being shaped at slide bar 331 front ends.The incision end of stopping discount 332 is a curved guiding surface, conveniently is pressed into correcting slide opening 23, and the end face that curved guiding surface is relative is the plane, has the function of spacing stopping.
The indent district 21 bottom surface 21b of the utility model ring guide through hole 22 radians such as grade are uniformly distributed with and preferably are shaped on three correcting slide openings 23, and manually button 3 correspondingly is shaped on three and wears the anticreep of joining mutually with correcting slide opening 23 and locate slide fastener 33.Three anticreep location slide fasteners 33 help the balance of manual button 3, and keep manual button 3 can not rotate.
Among the embodiment, the upper surface of key plate 31 is to be shaped on the bar groove 6 that matches with groove 5 on curved surface 31b and the curved surface 31b of arc.
The working method of the utility model is such: firmly press manual button 3; The resistance that manual button 3 overcomes back-moving spring 4 makes whole decline in indent district 21; In the process that manually button 3 descends; Switch triggering guide rod 32 slides along guide through hole 22 and correcting slide opening 23 respectively with anticreep location slide fastener 33, and switch triggering guide rod 32 drops to certain position and triggers the induction alarm circuit, realizes reporting to the police.When unclamping manual button 3; Manually button 3 moves up under the effect of back-moving spring 4; Switch triggering guide rod 32 breaks away from conduction position; Behind manual button 3 rising certain distances, because the spacing stopping effect of anticreep location slide fastener 33 stopping discounts 332 makes manual button 3 return to original initial conditions.
