Description
Technical field
The utility model relates to a kind of stadimeter, is the improvement technology of stadimeter specifically.
Background technology
At present, people measure the longer measurement of length instrument of point-to-point transmission and are generally tape measure, ruler, need two people's compounding practices just can finish when using tape measure length and can only measure straight length, if for runway or road surface telemeasurement, it is very inconvenient then to operate, also difficulty reaches requirement on precision, if measure then more improper with ruler.For this reason, people have designed a kind of stadimeter that adopts roller to measure length, as " a kind of wheeled type distance measuring apparatus " (ZL01254325.X), this stadimeter only needs one to hold the track that handle measures along needs by roller and cover, can on display screen, draw its distance, be easy to use simple and can measure length of curve.But inconvenience is carried in this product existence, the affected shortcoming of environment for use, and under in low temperature condition, the counting assembly in this stadimeter can lose effect, and in addition, this stadimeter also exists display screen to watch the not high shortcoming of inconvenience, measuring accuracy.
Summary of the invention
The purpose of this utility model provides a kind of easy to carry, result of use good, measuring accuracy is high stadimeter.
The utility model is achieved through the following technical solutions.
A kind of stadimeter comprises roller, support, handle and counting assembly, and roller is rack-mount, it is characterized in that: described support is an extension type long connecting rod.
The outer ring of described roller is provided with a rubber ring.
Uniform porose on the described roller circle, be provided with infrared and receiver with the corresponding connecting rod in hole site.
Described roller is provided with indicator stem, and indicator stem vertically down.
Described counting assembly is a digital electronic unit, and the power supply of digital electronic unit is positioned at the handle place, and power supply is made up of removable battery compartment and the battery that is installed in the battery compartment, and battery compartment is provided with the power supply output contact.
Display location in the described counting assembly is in the upper end of connecting rod, and an end of display screen can rotate around the axis and fold in the interior storage chamber of connecting rod.
Be provided with the magnet of inhaling mutually in described display screen and the storage chamber.
Scribble fluorescent powder on the described stadimeter.
Described stadimeter is provided with warning lamp.
The utility model compared with prior art has the following advantages.
Because the support in the utility model stadimeter is an extension type long connecting rod, each section of long connecting rod can be contracted in together when not using, thereby dwindle the volume of stadimeter greatly, made things convenient at ordinary times and carried, store; Display screen can rotate around the axis and fold in the interior storage chamber of connecting rod, when using range finding, display screen is rotated an angle of 90 degrees and connecting rod approximate vertical, again display screen is folded in the storage chamber when not using, so this display screen not only is convenient to watch the range finding result but also be convenient to collection; Indicator stem of installing on the roller and rubber ring mainly are to be convenient to determine the starting point of measuring and prevent that the phenomenon of skidding from appearring in roller in moving process, in addition, adopt the infrared ray reception can realize counting quickly and accurately, thereby improved the measuring accuracy of stadimeter with emitter.The power supply of digital electronic unit is placed the handle place, when under low temperature environment, using, can digital electronic unit be worked on, avoid power supply to lose efficacy at low temperatures by the hand temperature.Detachable battery case is convenient to install battery, is user-friendly to.

Embodiment
Below in conjunction with accompanying drawing the utility model stadimeter is described in further detail.
Mainly be made of with counting assembly roller 1, support 2, handle 21 to stadimeter shown in Figure 5 as Fig. 1, roller 1 is installed in the bottom of support 2, and support 2 is the long connecting rod of an extension type.The hypomere connecting rod can be pulled out from the epimere connecting rod in use, compression spring perhaps is installed between upper and lower strut, the hypomere connecting rod can be ejected from the epimere connecting rod by the switch on the lower link; When needs carry or deposit, the hypomere connecting rod is pressed in the epimere connecting rod, thereby reduces the volume of support.Counting assembly adopts mechanical counting device or digital electronic unit.Inductor in the digital electronic unit adopts infrared ray to receive with emitter and calculates the number of turns that roller rotates, infrared ray receives with emitter mainly to be made up of transmitter 31 and receiver 32, transmitter 31 is installed in respectively on the connecting rod of roller both sides with receiver 32, with the roller circle of transmitter 31 and receiver 32 opposite positions on be evenly equipped with a plurality of through holes 14, when roller 1 turns to diverse location, the signal that receiver 32 receives transmitter 31 emissions passes through hole 14 backs just to signal of counter emission, thereby finishes the counting of this position.The power supply 23 of digital electronic unit places handle 21 places, when using under low temperature environment, can digital electronic unit be worked on by the hand temperature, avoids power supply 23 to lose efficacy at low temperatures.Power supply is made up of removable battery compartment 24 and the batteries 25 that are installed in the battery compartment 24, and battery compartment is provided with the power supply output contact.During use, in the battery compartment 24 of multiple batteries 25 can being packed into earlier, and then battery compartment 24 snapped in the handle 21, during dismounting, when opening the battery compartment lid, battery compartment 24 ejects automatically in company with battery 25, so very easy to use.Mechanical counting device is mainly installed a driving gear and a follower gear on roller, driven gear shaft links to each other with mechanical counter, and the moving circle mechanical counter of roller revolution converts the number of turns to distance, thereby obtains the length of track.The display screen 4 that is positioned at the small end side can rotate around the axis and fold into the storage chamber of connecting rod, when using range finding, display screen is rotated an angle of 90 degrees and connecting rod approximate vertical, again display screen 4 is folded in the storage chamber when not using, be provided with the magnet of inhaling mutually 41,42 in display screen 4 and the storage chamber, so this display screen 4 not only is convenient to watch the range finding result but also be convenient to collection.The reset switch 22 of display screen 4 is arranged on the handle 21 of small end, when beginning to measure, pulling, reset switch 22 makes display place cleared condition, and then begin to promote stadimeter and find range, when covering tested track, pull the state that reset switch 22 is in display to stop to count again, write down last measurement result then, when carrying out if desired measuring next time, can pull reset switch 22 once more and make display place cleared condition.Roller 1 adopts metal material or plastic parts, roller 1 outer ring upper ring cap one rubber ring 11, and its fundamental purpose is to prevent that the phenomenon of skidding from appearring in roller 1 in moving process, thereby improves the measuring accuracy of stadimeter.Be provided with a vertical sign 12 of installing on roller 1, it is mainly used in the Origin And Destination of indication stadimeter.Use the stadia surveying distance at night for ease of the traffic police, on stadimeter, also coat layer of fluorescent powder, light-illuminating can reflect alarm signal on roller 1 time, in addition, also can utilize the power supply of stadimeter itself that warning lamp is installed, launch alarm signal, thereby increase the coefficient safe in utilization of stadimeter.
