Description
Technical field
The utility model relates to a kind of alarm, especially is convenient to measure the tape measure depth measure independent alarm of the cavern degree of depth and oil depot pasta.
Background technology
At present, mountaineer or exploring party usually need to measure the degree of depth of cavern on the road, need to measure the oil reserve in the oil depot in the staff of the oil depot work, and on the market this fathom and the instrument of pasta very in short supply.
The utility model content
For the cavern degree of depth or oil depot pasta are measured, the utility model provides a kind of tape measure depth measure independent alarm, can indicate cavern bottom surface or oil depot pasta by sounding, and read reading by tape measure, and is simple in structure, convenient and practical.
The technical scheme that its technical matters that solves the utility model adopts is: this tape measure depth measure independent alarm comprises switch, hummer, tape measure, spring, pouring weight, armature contact, fixed contact, shell and battery; This alarm is provided with a trapezoidal shell, switch and hummer are installed above the shell, upwards erect at the middle part of shell the cylinder that is communicated with shell, spring and pouring weight have been linked in sequence in the cylinder, the upper end of spring connects the head end of tape measure, the below of pouring weight is provided with armature contact and fixed contact successively along vertical curve, the bottom of shell is equipped with battery, fixed contact is fixedly mounted on above the battery, hummer, switch, battery and fixed contact are electrically connected by wire, and armature contact is electrically connected by wire with hummer and is unsettled.During use, Closing Switch, hand-held tape measure shell, alarm is put into cavern or oil depot downwards, and when body case of annunciator arrived cavern bottom surface or oil depot pasta, shell landed or swims in pasta and stop to fall, and pouring weight continues to fall, armature contact is depressed into causes the two to electrically contact on the fixed contact, the hummer sounding alarm reads simultaneously the tape measure scale and is cavern or the pasta degree of depth.
The beneficial effects of the utility model are: can indicate cavern bottom surface or oil depot pasta by sounding, and read reading by tape measure, and simple in structure, convenient and practical.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
1. switches among the figure, 2. hummer, 3. tape measure, 4. spring, 5. pouring weight, 6. armature contact, 7. fixed contact, 8. shell, 9 batteries.
Embodiment
In the drawings, this tape measure depth measure independent alarm comprises switch 1, hummer 2, tape measure 3, spring 4, pouring weight 5, metal clips 6, stator 7, shell 8 and battery 9; This alarm is provided with a trapezoidal shell 8, switch 1 and hummer 2 are installed above the shell 8, upwards erect at the middle part of shell 8 cylinder that is communicated with shell, spring 4 and pouring weight 5 have been linked in sequence in the cylinder, the upper end of spring 4 connects the head end of tape measure 3, the below of pouring weight 5 is provided with armature contact 6 and fixed contact 7 successively along vertical curve, the bottom of shell 8 is equipped with battery 9, fixed contact 7 is fixedly mounted on above the battery 9, hummer 2, switch 1, battery 9 and fixed contact 7 are electrically connected by wire, and armature contact 6 is electrically connected by wire with hummer 2 and is unsettled.During use, Closing Switch 1, hand-held tape measure 3 shells, alarm is put into cavern or oil depot downwards, and when body case of annunciator 8 arrived cavern bottom surfaces or oil depot pasta, shell 8 landed or swims in pasta and stop to fall, and pouring weight 5 continues to fall, armature contact 6 is depressed on the fixed contact 7 causes the two to electrically contact, hummer 2 sounding alarms read simultaneously tape measure 3 scales and are cavern or the pasta degree of depth.
