Abstract

The utility model relates to a sag gauge. The utility model is provided with a rectangular fan-shaped casing; the front of the casings is transparent; the inner side of the back of the casing is provided with a two-way dial with 0-90 DEG scales; the center of the dial is provided with a central shaft; a pointer is sheathed on the central shaft, and the lower part of the pointer is provided with a heavy pituitary; a locking button is arranged on the wall of the casing in front of the pointer. Therefore, the utility model has the advantages of simple structure, convenient operation, portability, high accuracy, low cost, etc.

Description

Sag gauge

The utility model relates to the instrument of a kind of measuring vertical or level inclination, refer in particular to the surveying instrument that pin type shows verticality or level inclination degree automatically.

At present, the simple and easy method of measuring vertical degree is exactly to take a rope, and a heavy hypophysis is fastened in the lower end, allow it sagging naturally then, and with this as the vertical extent that standard is observed other object, this method is widely used on the building ground, this is a kind of more original method.Also have plenty of senior instruments such as the level meter of utilization, as bubble formula level meter, the vertical extent of on basis, observing other object by the measurement surface level, because this is a kind of indirect measuring method, actual use less.In the higher use occasion of ask for something, the general measure verticality is to adopt the higher surveying instrument of precision.Using light is electrometric, and also useful electromechanical means is measured, because their use cost height, measuring accuracy is high and can not be applicable to the common survey occasion.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and the Sag gauge that provides a kind of utilization heavily to hang down pointer-type indication verticality.

The purpose of this utility model is finished by following technical solution, it has, and one side is transparent, the inboard housing that index dial is arranged of one side, the index dial center is provided with central shaft, is equipped with down the pointer of the heavy hypophysis of band on the axle, utilizes heavy hypophysis all the time to the measuring vertical degree that gets off.

The utility model is equipped with sleeve pipe and small casing on described central shaft, and sleeve pipe and small casing lay respectively at the front and back of pointer and are connected in respectively on the inwall of housing both sides, sleeve pipe is built-in with spring, be mounted with locking press button on the housing wall of spring outer end, and it is pressed on the spring terminal.

The utility model fan shape that also case design met at right angles, the inboard index dial of its one side is the double-deck scale of 0-90 degree.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a user mode synoptic diagram of the present utility model.

Below will the utility model is further introduced by accompanying drawing: a right angle fan shape housing 1, it is formed by connecting by peripheral gusset 4 by base plate 2 and panel 3, housing 1 is except base plate 2, all the other are made by transparent plastic sheet entirely, be provided with the centre zero scale dish 5 of 0--90 degree in the inboard of base plate 2, the center of index dial 5 is provided with a central shaft 6, be equipped with down pointer 8 on the axle with heavy hypophysis 7, on central shaft 6, also be equipped with sleeve pipe 9 and small casing 10, and they lay respectively at the front and back of pointer 8 and are connected in respectively on the inwall of housing 1, make pointer 8 axial location.Be mounted with spring 11 in sleeve pipe 9, being mounted with on the outer end housing wall of spring 11 can be inwardly by the locking press button 12 that advances, and this locking press button 12 is pressed on the end face of spring 11.During use, one side with housing 1 right angle is benchmark, be placed on the tested plane, or near on the tested wall, at this moment have the inclination angle because of tested plane or tested wall, the heavy hypophysis 7 of pointer 8 points to center of gravity all the time, and indicates an angle [alpha] on index dial 5, this angle is the inclination angle, i.e. the angle of inclination of tested wall.It is for tested plane equally, and the level inclination of also representing tested plane is α.Thereby this Sag gauge also can be convenient for measuring the degree of tilt of level, because index dial is a centre zero scale, promptly the both sides with the right angle are that benchmark respectively can reading.

The utility model compared with prior art has simple in structurely, easy to use, and easy to carry, has one Fixed accuracy, cost are again low, and be applied widely, and the bigger characteristics such as promotional value are arranged.
