Abstract

The utility model relates to a multipurpose angle square for skilled workers, which is mainly formed by mutually hinging a reference square 1 provided with an observation hole 7 and horizontal bubble pipes 9, 10, and a length square 2 which is provided with a semicircle angle plate 5 around a shaft 3. When the multipurpose angle square is used, the reference square is pasted on the reference surface of a workpiece firstly, and the angle required by the length square can be adjusted. The angle line can be directly drawn or the line segment can be directly measured by clinging to the length square directly, or the horizontal plane of the workpiece can be searched by the horizontal bubble pipes arranged on the reference square. The utility model is suitable for bench workers in shop floors, plate workers, woodworkers, etc., and has the advantages of simple structure, easy fabrication and convenient use.

Description

Multipurpose angle square for skilled worker

The utility model relates to the tolerance of skilled worker's use, the workshop appliance of line, is a kind of skilled worker's Multipurpose angle square that angle changes function, has the searching horizontal reference concurrently that mainly has.

The workshop skilled worker adopts protractor to carry out to angle tolerance line usually, if will seek the workpiece level reference simultaneously the time, and also must be auxiliary with level meter in addition.Because protractor is normally made with transparent organic glass, repeatedly contact back wearing and tearing easily with workpiece, and use is also not too convenient, if will add the then more apparent trouble of usage level instrument again.

Design objective of the present utility model is to design a kind of bevel protractor and level meter of integrating at the problem of above-mentioned prior art existence, is convenient to the Multipurpose angle square that the workshop skilled worker measures line.

Skilled worker's Multipurpose angle square is mainly constituted by station meter and length chi, characteristics are to link by hinge axis between station meter and the length chi, it is the half garden angle board at center that the length chi has with the hinge axis at the hinge axle head, station meter is fluted by the hinge axle head, the angle board of length chi can trackslip in groove, can observe the hole of angle board angle on the station meter in addition, hole edge one end is carved with directrix, the other end is provided with the spirit bubble pipe that exposes, the long limit end of station meter also is provided with the spirit bubble pipe that flushes with long limit, and compressible wing nut also is housed on the hinge axis.

Station meter and length chi the utility model has the advantages that: owing to can turn round around hinge axis, if reference edge with one of the station meter two long limit ends workpiece that reclines, then the length chi can mark 0 °～180 ° arbitrarily angled line on workpiece, it is convenient and accurate that translation-angle seems, and can also measure line segment easily on angle line.Because with mutually perpendicular spirit bubble pipe in length and breadth, chi reclined, and to seek datum water level more convenient for workpiece on the station meter.Being particularly suitable for line such as pincers worker, panel beating worker, carpenter uses.

Fig. 1 is the signal of the utility model front view.

Fig. 2 is the A-A diagrammatic cross-section of Fig. 1.

Skilled worker's Multipurpose angle square is mainly constituted by station meter 1 and length chi 2, has screw thread can lean on wing nut 4 to screw on the hinge axis 3 or unclamps.Also having with hinge axis 3 on the length chi 2 is the half garden angle board 5 at center, and angle board 5 can trackslip for 6 li at the groove of station meter 1.Have on the station meter 1 and observe

hole

7,7 edges, hole, one end is carved with directrix 8, directly can with the required angular alignment on the angle board 5.The other end relative with directrix 8 at 7 edges, hole is provided with the spirit bubble pipe 9 that exposes, and expose spirit bubble pipe 10 what the long limit of station meter 1 end was provided with also that another flushes with long limit, and the center line of

spirit bubble pipe

9,10 is orthogonal.

Skilled worker's reading angular value can be marked with the two

rows angle value

11,12 of anti-order mutually at scale for convenience.

Claims

1, skilled worker's Multipurpose angle square mainly is made up of station meter 1 and length chi 2, it is characterized in that linking by hinge axis 3 between station meter 1 and the length chi 2, it is the half garden angle board 5 at center that length chi 2 has with the hinge axis, station meter 1 is by hinge axis 3 ends fluted 6, angle board 5 can trackslip in groove 6, can observe the hole 7 of angle board 5 angles on the station meter 1 in addition, hole 7 edges one end is carved with directrix 8, the other end is provided with the spirit bubble pipe 9 that exposes, the long limit end of station meter 1 is provided with the spirit bubble pipe 10 that flushes with long limit, spirit bubble pipe 9,10 center lines are orthogonal, and wing nut 4 is housed on the hinge axis 3.

2, Multipurpose angle square according to claim 1 is characterized in that the scale on the half garden angle board 5 is marked with the two rows angle value 11,12 of anti-order mutually.
