Abstract

The utility model relates to a pocket-size height-range finder which mainly comprises a base, a sector gear, a driven gear, an amplification telescope, a pointer, a dial plate and a braking strip, wherein the amplification telescope is arranged at the upmost end of the base; the sector gear is positioned at one end of the base under the amplification telescope; the driven gear is meshed with the sector gear and is arranged together with the dial plate in a concentric way; a wheel axle of a driven wheel is provided with the pointer; and braking strip is arranged under the driven gear and is controlled by a brake button. The pocket-size height-range finder has small volume, light weight, convenient carrying, low price and easy operation, is accurate in measurement, time-saving and labor-saving as well as high in working efficiency, and amplifies the measurement angle by six times to the utmost extent, and thus greatly improving the measurement accuracy. The instrument is applicable to the measurement work of towns, planes, hills, plateaus, forests, mountainous areas and the water surface, can work in the environment of high-intensity magnetic field and electric field, and can measure the angle of elevation from the lower part to the higher part, and the depression angle from the higher part to the lower part.

Description

A kind of vest-pocket altimeter range finder

Technical field

The utility model relates to a kind of measuring height and distance instrument that the elevation angle that measures or the angle of depression are amplified, and can be used for measuring height and distance by departments such as electric power, telecommunications, military affairs, urban construction, land and water transportation, forest reserves generaI investigations.

Background technology

Along with high speed development of national economy, a kind of cheap, in light weight, easy to carry, measuring height and distance instrument that measuring accuracy is high is badly in need of in a lot of departments.Measuring height and distance instrument commonly used at present is meant that the pin institute how and the scope of actual measurement pitch angle are 1: 1, therefore make measuring accuracy not high, well-known, survey is high, the most frequently used angle of range finding is below 90 °, 60 ° with lower angle use at most, the pitch angle that surpasses 90 ° does not need forever; Have plenty of under given conditions and measure, the price that has is higher or carry inconvenience, brings certain difficulty to the user.In sum, measuring accuracy is increased substantially, existing measuring equipment still can not finely solve.

Summary of the invention

The technical problems to be solved in the utility model is: design a kind of measuring accuracy height, easy to carry, cheap, have on measured object ground under the situation of obstacle, also can measure the height of measured object or the vest-pocket altimeter range finder device of horizontal range, can increase work efficiency greatly and work quality.

The technical scheme that solution the utility model problem is taked is: this instrument mainly is made up of base, sector gear, follower gear, amplification telescope, pointer, index dial, braking bar, amplify telescope and be arranged on base topmost, the center of circle of sector gear is located at base one end, amplifies below the telescope, follower gear is installed in below the sector gear and with sector gear and meshes, 120 degree sector gears, it rotates 60 degree, rotate a week with the follower gear of its engagement, the sector gear of 180 degree, it rotates 90 degree, rotates a week with the follower gear of its engagement; Follower gear and index dial concentric, pointer are installed on the wheel shaft of follower gear; The braking bar is located at the follower gear below perpendicular to the circumference of engaged wheel, by a locking key control.

Be provided with balancing weight in the sector gear bottom.

On the braking bar locating slot is arranged, leading portion is with a compression spring; Have a braking clamp to be stuck in the locating slot on the locking key, the front is installed a brake check spring and is withstood locking key.

Be provided with a braking cushion rubber bumper in braking bar front end.

A small-sized function calculator is installed on the base of this instrument other end.

The profile of tooth of transmission gear adopts the herringbone tooth.

Good effect of the present utility model is: little, in light weight, easy to carry, cheap, the easy operation of instrument volume; Less demanding to measurement data, do not need falsework to get final product work; If the band A-frame, measuring accuracy is higher; Time saving and energy saving, high efficiency; Can make takes measurement of an angle amplifies 4 times, and maximum scalable 6 times, so measuring accuracy improves greatly; This instrument is applicable to cities and towns, Plain, hills, plateau, forest, mountain area and surface measurement work; Be applicable to high and cold, high temperature is regional; Can under high-intensity magnetic field, highfield environment, work; Because of recording the elevation angle, the angle of depression, so can survey eminence, all can from lower from eminence survey lower object.

Description of drawings

Accompanying drawing 1 is to be synoptic diagram of the present utility model; Accompanying drawing 2 is that A-A is to cut-open view.

Embodiment

As shown in drawings, this instrument mainly is made up of base 2, sector gear 10, follower gear 11, amplification telescope 1, pointer 5, index dial 4, braking bar 8, amplify telescope 1 and be arranged on base 2 topmost, sector gear 10 is located at base 2 one ends, amplifies below the telescope 1, is inlaid with mercury balancing weight 9 at 10 times middle parts of sector gear.The fan shape angle degree of sector gear 10 adopts 120 °, drives a follower gear 11, when sector gear 10 rotates 60 °, and 11 1 weeks of rotation of follower gear; Produce error for preventing gear drive and pressing to impact when locking key 14 braking bars 8 are braked, the profile of tooth of transmission gear adopts the herringbone tooth.Follower gear 11 and index dial 4 concentrics are coated with a cloche 7 on the index dial 4; Pointer 5 is installed on the wheel shaft of follower gear 11, and when pointer 5 rotated a week, the angle that sign is measured was 60 °, in 360 ° scope, mark 60 ° scale, so, pointer institute how is 6: 1 with actual measurement pitch angle scope, so its precision just improves 6 times.Braking bar 8 is located in the gathering sill on follower gear 11 belows, the base 2 perpendicular to the circumference of follower gear 11, by 14 controls of a locking key; A side that on braking bar 8, contacts with locking key 14, one locating slot is arranged, and leading portion is with a compression spring 13, and the end is provided with a braking cushion rubber bumper 12, locating slot on one braking clamp being arranged on the locking key 14 and braking bar 8 cooperates, and the front is equipped with a brake check spring 15.Be convenience of calculation, a small-sized function calculator 6 is installed on the base 2 of this instrument other end.

Pick up measuring instrument, eyes press close to amplify the eyepiece of telescope 1, amplify the middle cross point of telescope 1 and aim at the measured object measurement point, press locking key 14, compression spring 13 discharges, and braking bar 8 ejects under the effect of compression spring 13, withstands follower gear 11, make dial needle 5 location, play braking action.Read index dial 4 shown angles,, can calculate the distance and the height of measured object very soon the small-sized function calculator 6 on the survey numerical value input instrument.
