Abstract
The utility model relates to a mechanical sensor for an alarm, which is characterized in that when an induction line 15 is pulled, a control sheet 37 is pushed by the flange 38 of a slide block 30, a microswitch 36 is switched on, and the alarm signal is sent out from the alarm. The utility model has the advantages of low cost, convenient implantation by users, etc., and the utility model is suitable for the place of installing the alarm of the buildings.
Description
The utility model relates to a kind of electrical switching contact operating mechanism, the mechanical sensor that particularly a kind of alarm is used.
The mechanical sensor that existing alarm is used, the mechanical sensor that the alarm that provides as Taiwan patent 80210222 is used comprises at the bottom of the box, lid, the line of induction, fork, microswitch, feeler lever, two microswitches of interior layout at the bottom of its box, feeler lever places between two microswitches, fork is connected with feeler lever with the line of induction respectively, when the line of induction was cut off or spurred, feeler lever touched microswitch, makes alarm send alerting signal.The defective of this sensor is: must adopt two microswitches, cost is higher, especially when this sensor of installing, because distance needs to adjust a little usually between sensor body and the buildings, quite bothers but do this adjustment.
The mechanical sensor that provides a kind of new alarm to use is provided the purpose of this utility model, and a slide block with the fork interlock is set, and a microswitch that is controlled by the slide block action adopts length-adjustable link between sensor body and the buildings.
Fig. 1 is the three-dimensional exploded view of this sensor.
Fig. 2 faces action diagram for Fig. 1.
Fig. 3 is the side cutaway view of Fig. 1.
The technical measures that realize the utility model purpose are: slide block 30 and the control strip 37 with fork 11 interlocks is set, the inner face place of slide block 30 is provided with groove 31 and flange 38, microswitch 36 is arranged in a side of slide block 30, on the moving contact of one termination microswitch 36 of control strip 37, the other end places in the groove 31 of slide block 30, and during the pulling line of induction, the flange 38 of slide block 30 promotes control strip 37, make microswitch 36 conductings, alarm sends alarm signal; Attaching parts 50 between sensor body and the building are provided with length adjustment device, make this sensor installing convenient.
Further describe the design's particular content below in conjunction with accompanying drawing.
The design's sensor, comprise at the bottom of the box, lid, the line of induction, fork, microswitch, link between sensor body and the buildings, the line of induction is connected with fork, during the pulling line of induction, the microswitch conducting, it is characterized in that: this sensor is provided with a slide block 30, a microswitch 36, a control strip 37, wherein slide block 30 two ends are provided with stay column 32,33, the inner face place is provided with groove 31 and flange 38, and the bottom is provided with spacing bumping post 301, and slide block 30 is arranged in by intermediate plate 16, in 17 clip slots that constitute, the spacing bumping post 301 of its underpart places at the bottom of the box in the groove 300, microswitch 36 is arranged in a side of intermediate plate 16, and an end of fork 11 is fixed at the bottom of the box on 10 by rotary pair 12, and its other end is connected with Chinese toon post 14 by spring 13, fork 30 left parts are connected with the line of induction 15, right part is connected with the stay column 32 of slide block 30 by steel wire 34, and the stay column 33 of slide block 30 is fixed on the Chinese toon post 35 by spring 130, and spacing bumping post 18 is used to limit the displacement of fork 11, one termination microswitch, 36 moving contacts of control strip 37, its other end places in the groove 31 of slide block 30; This sensor body adopts a length-adjustable link 50 to be fixed on the contiguous buildings.
Above-mentioned link 50 by nut 51,52, screw rod 53,56, tune part 54, keeper 57 is formed, wherein the thread rotary orientation of screw rod 53 is opposite with screw rod 56 thread rotary orientations, the two ends that tune part 54 are respectively equipped with the screw that is complementary with screw rod 53,56, screw rod 53 other ends pass at the bottom of the box 10, and be fixed at the bottom of the box on 10 with nut 51,52, the extension of screw rod 56 other ends is connected with keeper 57; Tune part 54 and be provided with a perspective window 55 of being with scale, when tuning part 54, link 50 length change, and observe the data that 55 interpretations of perspective window go out length variations.Lid 20 covers at the bottom of the box on 10.
With prior art relatively, this programme has the following advantages:
1. only adopt a microswitch, reduced production cost;
2. adopt length-adjustable link to be connected between sensor body and the close to buildings, but and interpretation go out to regulate the data of back link length variations, laying brings great convenience to sensor.
