Description

Inner corner trim, external corner corner protractor

Technical field

The utility model relates to the tolerance utensil, is a kind of protractor of measuring corner interior angle and pillar exterior angle angle specifically.

Background technology

In construction work or decorative engineering, often need to measure the angle of corner or pillar, particularly in cabinet industry artificial stone and corner, the butt joint of pillar is very important, especially run into the corner of abnormity or pillar especially handled, one is careless slightly, and artificial stone is scrapped; The ground patch block also can be run into similar situation.

At this moment, we may need a kind of measurement facility to measure the angle of corner or pillar.Usually the angle square of people's use can't be set about in the face of this situation, and a shot in the locker may be done mould with regard to cardboard exactly, and is so both bothersome, again out of true.

Summary of the invention

The purpose of this utility model provides a kind of protractor of measuring inner corner trim, external corner corner angle.

The feature of described inner corner trim, external corner corner protractor is: this protractor is connected to form by rotating shaft by flexible handle, fan dial; Described flexible handle is divided into the left flexible handle and the right movable magnetic holder two parts that can rotate around the axis; The narrow end of described fan dial is connected in the rotating shaft, and can rotate around the shaft, a plurality of fan dial overlaids.

The superiors are last L shaped index dial in the described fan dial, and orlop is following L shaped index dial, and there are a plurality of Z-shaped index dials the centre, and the little head end of going up L shaped index dial and following L shaped index dial is connected with the flexible handle vertical fixing.

The utility model can be measured the corner angle of inner corner trim, external corner.Modern design, the letter joint is exquisite, and cost is low; Easy to use, be simple and easy to usefulness, can be widely used at architectural decoration.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is the local enlarged diagram of the utility model,

Among the figure: 1-left flexible handle, 2-right movable magnetic holder, 3-rotating shaft, 4-upward L shaped index dials, 5-following L shaped index dial, 6-Z-shaped index dial, 7-L shaped index dial right flank, 8-Z-shaped index dial right flank.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified: inner corner trim, external corner corner protractor as shown in Fig. 1,2, it is characterized in that: this protractor is made up of flexible handle, fan dial; Described flexible handle is divided into 3 left flexible handle 1 and right movable magnetic holder 2 two parts that rotate around the shaft; Described fan dial is to be connected in the rotating shaft 3 by fan-shaped narrow end, and can be around the shaft 3 rotations fan-shaped,

The narrow end of described fan dial is connected in the

rotating shaft

3, and 3 rotations around the shaft, a plurality of fan dial overlaids.The superiors are last L shaped index dial 4 in the described fan dial, and orlop is following L shaped index dial 5, and there are a plurality of Z-shaped index dials 6 centre, and the little head end of going up L shaped index dial 4 and following L shaped index dial 5 is connected with the flexible handle vertical fixing.

Right movable magnetic holder 2 is made for magnetic material, and Z-shaped index dial 6 is for making with the ferrous material that this magnetic material is inhaled mutually, perhaps Z-shaped index dial right flank 8 and the L shaped index dial right flank 7 employing ferrous materials making of going up L shaped index dial 4.

In an embodiment, each fan dial angle in the described fan dial is 30 degree, but last L shaped index dial 4 read text scale of the superiors are 30 degree, but other fan dial read text scale is 27 degree, because the crotch of one side reaches and the crotch of an index dial on it has partly occupied a part of position, this a part of position can not reading.

Going up L shaped index dial 4 microcephalies is vertically fixed on the left flexible handle 1, L shaped eave tile last L shaped index dial 4 and fan-shaped wide end xsect down is that L shaped, microcephaly is vertically fixed on the eave tile following L shaped index dial 5 up on the right movable magnetic holder 2, and last L shaped index dial 4 and down 10 fan-shaped angles between the L shaped index dial 5 be 30 degree, fan-shaped wide end xsect be Z-shaped, Z-shaped left side eave tile up, eave tile Z-shaped index dial 6 down in the right forms.Z-shaped index dial right flank 8 and right movable magnetic holder 2 adhesives under the collapse state.

Collapse state: with left flexible handle 1 and right movable magnetic holder 2 relative motions, make the angle between it narrow down to 30 degree, at this moment, go up L shaped index dial 4, following L shaped index dial 5 and 10 Z-shaped index dials 6 and be neat overlapping shape, go up the L shaped index dial right flank 7 of L shaped index dial 4 and the Z-shaped index dial right flank 8 of 10 Z-shaped index dials 6 and all be adsorbed on the right movable magnetic holder 2.

Measure the angle in corner: the protractor tip of collapse state is propped up the corner, corner, simultaneously protractor one side flexible handle is attached on the left side metope in corner; Pinning the left flexible handle 1 that is attached to left side metope with left hand, pinch right movable magnetic holder 2 with the right hand simultaneously, is the axle center with rotating shaft 3, slowly face wall face rotation to the right; Because going up L shaped index dial 4 and 10 Z-shaped index dials 6 all is adsorbed on the right movable magnetic holder 2, at the movable magnetic holder 2 in the right side to the right in the motion process of face wall face, when rotational angle when the fan-shaped angle of next index dial, last index dial eave tile and next index dial eave tile up down collided, under the pulling force effect, make next index dial break away from adsorbed state, like this, index dial can launch from top to bottom successively in order, and movable magnetic holder 2 is attached on the metope of the right side up to the right side.Be a state after launching as shown in Figure 1, 2.At this moment, just can the reading angular data.

As shown in Figure 2: the mark of each index dial number of degrees all is to increase progressively mark from right to left side, except last L shaped index dial 4 is full 30 scales are annotated, other index dial is because last index dial eave tile down and this index dial eave tile up have certain width, so annotate by 27 scales, such as the mark on the last L shaped index dial 4 is 0～30 degree from right to left, mark on the 1st Z-shaped index dial 6 is 30 degree～57 degree from right to left, mark on the 2nd Z-shaped index dial 6 is 57 degree～84 degree from right to left ... mark on the 10th Z-shaped index dial 6 is 273 degree～300 degree from right to left, mark on the L shaped index dial 5 is 300 degree～327 degree from right to left down, and in fact the full scale of each fan dial is 30 degree.

Reading angular data: as shown in Figure 2: be a state after index dial launches.The read data principle is: see mark on the index dial that still is adsorbed on right movable magnetic holder 2 vertically downward from last right flank that breaks away from the index dial of the attached state of magnetic, the mark of its correspondence is exactly the angle in this corner.Such as: go up L shaped index dial 4 and broken away from adsorbed state, the 1st Z-shaped index dial 6 still is adsorbed on the right movable magnetic holder 2, at this moment seeing the 1st mark on the Z-shaped index dial 6 vertically downward from the L shaped index dial right flank 7 of last L shaped index dial 4, is exactly the angle at this angle; As shown in Figure 2 under the situation, the 1st Z-shaped index dial 6 broken away from adsorbed state, the 2nd Z-shaped index dial 6 still is adsorbed on the right movable magnetic holder 2, then see the 2nd the mark master on the Z-shaped index dial 6 vertically downward from the Z-shaped index dial right flank 8 of the 1st Z-shaped index dial 6, this is the angle with regard to this angle, is 76 degree as shown in Figure 2.The outer angle measuring method of pillar is the same, be the final number of degrees be that 360 degree deduct the numerical value that protractor is read.
