Abstract

The utility model relates to a rolling type range finder which is characterized in that: the range finder includes roller wheel, push rod hinged with the center of the roller wheel by lower end cross bar, active conical gear connected firmly in the center of the roller wheel, having cross bar penetrating via hole, and mechanical type counting converter fixed on the lower part of the push rod; the input end of the mechanical counting converter thereon is provided with passive conical gear driven by active conical gear. The range finder is proper in design, simple in structure, convenient in operation. The range finder can effectively solve the defects such as slow measuring speed and invisual data reading and can also measure curves and long distances conveniently and rapidly when only one operator is needed. The utility model is people-saving and labor-saving, low in cost and has greater application and development prospects.

Description

The tumbling-type stadimeter

Affiliated technical field

The utility model relates to a kind of tumbling-type stadimeter.

Background technology

The most frequently used instrument of past measurement distance is tape measure and ruler.Use tape measure and ruler, relatively simple for structure, can finish general range finding work, but its measuring speed is slow, the range finding reading is not directly perceived, and often needs the above cooperation of two people just can finish measurement, especially is difficult for carrying out the measurement of curve and long distance.Present employed viameter also all adopts the structure of belt tape measure basically.Use some viameter measuring distance, though improved the accuracy and the degree of accuracy of reading, structure is complicated mostly, and price is also relatively more expensive.

Summary of the invention

The purpose of this utility model just is to provide a kind of tumbling-type stadimeter, and it is simple in structure, and is easy to operate, can solve effectively that measuring speed is slow, reading shortcoming intuitively not, and only needs an operator just can finish surveying work, and people from province is laborsaving.

The utility model is to constitute like this: it comprises roller, through lower end cross bar and the push rod that the roller middle part is hinged, is fixed in that roller is supermedial to have the initiative taper generating gear that cross bar runs through through hole, and the mechanical type that is fixed in the push rod bottom is counted converter; The input end of described mechanical type counting converter is provided with the passive cone gear that is driven by the initiative taper generating gear.

Than existing stadimeter, the utility model is reasonable in design, and is simple in structure, and it can carry out the measurement of curve and long distance quickly and easily, and people from province is laborsaving, and reading is directly perceived.

Description of drawings

Fig. 1 is the main pseudosection of embodiment

Embodiment

Introduce concrete device of the present utility model and working condition below in conjunction with accompanying drawing:

With reference to Fig. 1, the concrete device of present embodiment comprises: roller 1, and the push rod 2 that in the middle part of lower end cross bar and roller, is hinged, the upper end of this push rod is provided with handle 7; Be located at that roller is supermedial to have the initiative taper generating gear 3 that cross bar runs through through hole, and the mechanical type counting converter 4 that is fixed in the push rod bottom, on the input end of counting converter, be hinged with the passive cone gear 5 that is meshed with aforementioned initiative taper generating gear.

In addition, the leading section at stadimeter is provided with a telescopic aiming stake 6 in order to the location.

The girth of roller of the present utility model can be designed to different length such as 1m etc. as required.Grasp handle during work, sight makes eyes 8, aiming stake 7, object of reference 9 sight alignments by taking aim at the object of reference of the selected distant place of mark projection, thereby guarantees that the operator keeps point-blank at the route that when measuring roller is walked of advancing.When roller rolls forward, will drive the initiative taper generating gear rotation that cross bar runs through through hole that has of being located at the roller middle part, rotate thereby drive the passive cone gear that is meshed with it.Display window by mechanical type counting converter directly reads measured distance subsequently.

The utility model is reasonable in design, simple in structure, easy to operate, it can solve effectively that measuring speed is slow, reading shortcoming intuitively not, and can only need to carry out the measurement of curve and long distance quickly and easily under an operator's the situation, people from province is laborsaving, with low cost, have bigger application development prospect.

Claims

1, a kind of tumbling-type stadimeter, it is characterized in that: comprise roller, through the push rod that lower end cross bar and roller middle part is hinged, be fixed in that roller is supermedial to have the initiative taper generating gear that cross bar runs through through hole, and the mechanical type counting converter that is fixed in the push rod bottom; The input end of described mechanical type counting converter is provided with the passive cone gear that is driven by the initiative taper generating gear.
