Abstract

The utility model relates to a declining angle gauge for measuring the declining angle of an object, which is the structural improvement of a block level gauge. The declining angle gauge is composed of a circular annular transparent tube 1, a dial disc 2 and a square frame 3, wherein, liquid 4, a bubble 5 and a pointer 6 are arranged in the circular annular transparent tube 1; the density of the pointer 6 is a little smaller than the density of the liquid; the centre of gravity of the pointer is positioned at the pointer root. The disc plane of the dial disc and the circular plane composed of the maximum radius R of the circular annular transparent tube are positioned at the same plane, and are vertical to the bottom of the square frame. The declining angle gauge is used for measuring the declining angle of the object; the declining angle value of the object on the dial disc is indicated by the pointer 6 in the circular annular transparent tube. The utility model overcomes the defect that the block level gauge is not capable of measuring the declining angle of any objects and has no dial disc for displaying angle value.

Description

Angle gauge for measuring declining angle of object

The present invention relates to the improvement of air-bubble level structure.

But existing air-bubble level inspected object inclination angle is 0 °, 45 °, 90 ° or is the particular value of a certain formulation, arbitrary angle that can not inspected object; Placing air-bubble level on testee inclines face the time, is whether more difficult determined level instrument length direction is placed along the incline direction of face of object with naked eyes; Be the inclination angle of representing object with the bubble volume position during detection, how many no index dial display scale numbers is so can not accurately indicate the angle of inclination of object.

The utility model has been invented a kind of angle of inclination that can detect arbitrary objects in order to overcome above-mentioned the deficiencies in the prior art, scope from 0 ° to 90 ° all can inclinator.This inclinator is made of annular transparent tube 1, index dial 2 and quadra 3.

As shown in Figure 1: annular transparent tube 1 one ends sealings, other end opening, useable glass or other transparent substance are made, putting into liquid 4(liquid from openend can be water), bubble 5 and pointer 6, and block opening part and avoid outside liquid 4 effusers.6 fens needle points of pointer and crown two parts, the similar arrow of needle point, the similar ball of the crown, the volume of pointer is slightly larger than the volume that pointer arranges liquid, and promptly the density of pointer is slightly less than density of liquid; The length of pointer is less than annular transparent tube interior diameter; The centre of gravity place of pointer is at the crown, and with its Position Design on the axis of symmetry of pointer, the crown of pointer will be immersed in the liquid 4, the needle point of pointer is the interface of emersion bubble and liquid vertically, enter in the bubble, the bubble volume of packing into just makes the pointer needle point will touch the inner tubal wall of annular transparent tube.The bottom of annular transparent tube and quadra is fixed, promptly taken off 7 in the quadra bottom, with annular transparent tube (dotted portion) and bottom adhesive together with cementing agent.In the annular transparent tube for center of circle R be that radius determined with O perimeter line on rectify into index dial 2, the disc that dial face and annular transparent tube maximum radius R are constituted coexists on the plane, and vertical with the quadra bottom surface, the bottom surface is long parallel.The two sides of index dial 2 indicates 0 ° to 90 ° scale mark and corresponding number of degrees value respectively, and the extended line of every scale mark all intersects at O place, the center of circle of annular transparent tube.The way of rectifying index dial and being fixed is: take off 8 in the quadra top, index dial 2 is inserted into the bottom downwards from quadra top, aim at annular transparent tube shell with O for after center of circle R is the perimeter line that radius determined, cover and fixing 8 in the quadra top, around in the periphery of index dial and the square box, bond together with cementing agent.Regulate index dial 2 and annular transparent tube 1, the pointer needle point is just in time indicated on 0 ° of line when making the bottom surface horizontal positioned of quadra 3, and the card of index dial 2 is parallel with the quadra bottom side length, can use.

Detection principle of the present utility model is as shown in Figure 2: when the bottom surface length of side of inclinator is placed on the testee inclination angle is the bevel direction of α (if do not place along bevel direction, pointer meeting off scale card, constitute an angle with dial face, adjust the placement direction of inclinator, till pointer and dial face are at grade), bubble 5 and pointer 6 will move to the peak in the annular transparent tube, stop motion when the peak and static, pointer 6 are subjected to vertically upward a buoyancy all the time makes the sensing of pointer needle point constant straight up.Can prove that the pointer 6 and the angle of 0 ° of line of dial face are exactly the inclination alpha on testee inclined-plane with geometric knowledge, therefore, the pointer needle point over against index dial on number of division be exactly the inclination angle number of degrees of object to be detected.
