Abstract
The utility model relates to an angle measurer which is mainly used for accurately and fast measuring an angle between a tilted object and a horizontal plane. The utility model measures an angle by making use of a principle that a weight dropper is always vertical and downward under the gravity action. In order to avoid the phenomena that a weight dropper continuously swings fore and after and left and right and the reading is not accurate, the utility model adopts two gears which are mutually meshed, producing a damping action which causes the weight dropper to fast stop swinging left and right. The weight dropper is arranged between a bracket and a casing, preventing the fore-and-aft swing of the weight dropper. Thus, a pointer is steady and can be fast fixed and the reading is accurate.
Description
This angular instrument is mainly used in folded angle between accurate measurement tilting body and the surface level.
This angular instrument is on the basis of the angle measurement pattern of in the past using, and utilizes weight, adopts two and stings the way that the gear that contains comes damping mutually, and pointer is fixed up very soon, makes it very fast reading.Angle measurement pattern in the past more can not very accurate, very fast reading when especially measuring moving object because the inertia effect of weight exists the slow problem of reading.Novel angular instrument has overcome deficiency in the past owing to taked the way of gear damping, can very fast, very accurate reading, and especially advantage is more obvious when measuring moving object.
This angular instrument has overcome deficiency in the past, has adopted the mode of gear damping that pointer is fixed up very soon.By the interlocking of two gears, produce resistance, pointer can not made it to stop very soon, immediately reading number owing to inertia swings.The result is an accuracy of reading, and efficient improves.
This angular instrument outward appearance is square, and inside mainly is made up of 3 parts: point gear, gear mechanism and cum rights.Point gear mainly is made up of pointer and weight, and the motion that is driven pointer by the motion of weight makes it reading.Gear mechanism mainly is made up of two engaged gears, and the engaged generation resistance by gear stops pointer very soon.Weight swinging center, hand motion center are coaxial with a certain gear center of circle, so just play damping action.Cum rights mainly is made up of index dial, support and shell etc., and support plays a supportive role, and the appropriate gap between support and the shell can make weight avoid swing.
Angle measurement pattern in the past is not owing to adopt damping unit, or the damping unit time grown and will lose efficacy, so reading is very slow, inaccurate.This utility model has adopted damping unit, and device can not lose efficacy because of the prolongation of time.Improve the accuracy rate and the work efficiency of reading.
Further specify structure of the present utility model below in conjunction with accompanying drawing.As accompanying drawing: Fig. 1 is the utility model gear mechanism front view
Fig. 2 analyses type gear mechanism left side view for this practicality
Fig. 3 is the utility model situation map in actual applications.
By Fig. 1 and Fig. 2 as can be seen, weight is because action of gravity always will be straight down, when surveying tilting body, weight drives pointer deflects pointer, reads angle on index dial, in addition, because cogged drag effect stops pointer very soon, just can read reading immediately.
As seen in Figure 3, situation in actual applications can not only be read angle value.
And on index dial, do suitable calculating and line, can also read the drop h of measurement point and surface level, further other key elements of right-angle triangle as can be known.
