Description

Guiding rule capable of measuring perpendicularity of template

Technical Field

The utility model belongs to the engineering survey field especially relates to a straightness's guiding ruler hangs down of measurable quantity template.

Background

In current wall post template work progress, there is the inconvenient problem of using the guiding ruler to measure the straightness data that hangs down because wall post template is equipped with primary and secondary fossil fragments. In the prior construction, the traditional method for measuring the perpendicularity of the template is often used, and the method mainly comprises two methods. One is a plumb bob method, in which one person temporarily fixes a plumb bob above a template, and after the plumb bob is stationary, the other person can measure with a box ruler. One method is to use infrared level meter method, one person sets the infrared level meter at one end of the wall model, and makes the center aligning point of the lower part align with the wall column control line, then opens the vertical line, another person commands another person to fine-tune the instrument at the other end of the wall model, and observes that the box ruler can start to measure after the vertical line and the wall column control line coincide. However, the prior art has many disadvantages, such as inconvenient operation by one person, inconvenient implementation of the plumb bob method under windy conditions, large power consumption of the infrared level meter, frequent battery replacement, and the like.

Chinese patent No. CN200920254656.0 discloses a guiding rule capable of measuring perpendicularity of a template, which changes the opening and closing states of supporting legs according to the difference of the objects to be measured, so as to achieve the purpose of measuring different measured objects. The limitations of this device are as follows.

Firstly, a rough surface cannot be conveniently measured, and when the support legs are folded for measurement, the measurement precision is greatly lower than that of a common guiding rule due to the fact that the length of the support legs is much longer than that of the guiding rule of the common guiding rule; when the supporting legs are opened for measurement, the supporting legs support a large space, so that the measurement can hardly be carried out in a narrow space, and even in a spacious space, the measurement person is inconvenient due to excessive occupied space.

And secondly, the supporting legs cannot be fixed, and the adjusted angle cannot be locked due to the fact that the supporting leg fixing device is not arranged. The length is 1 meter or 2 meters when ordinary guiding rule uses, and in the measurement process of carrying out the wall post template, the user can't use the device nearly alone.

And thirdly, the distance between the support legs is small, and the distance between the support legs after the support legs are opened is smaller than that between the support legs of the common guiding rule, so that the measurement precision is low.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.

Detailed Description

An embodiment of the present invention will be described with reference to the accompanying drawings.

In the description of the present invention, it should be noted that the directions or positional relationships indicated by "top", "bottom", "both ends", etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

This device uses traditional guiding rule as the basis, is provided with the cavity in 1 top of guiding rule body and bottom, can hold flexible backing 2, and flexible backing 2 nestification is in the cavity, and every backing comprises two telescopic joint. One end of each telescopic joint close to the guiding ruler body 1 is provided with a buckle 3 with a snap spring, and holes corresponding to the positions of the buckles 3 when the telescopic backing feet 2 are completely extended out are formed in the larger telescopic joint and the guiding ruler body 1 in the two telescopic joints. The structure is similar to a sliding staff. When the telescopic back rest 2 retracts to the maximum, as shown in fig. 1, the telescopic back rest 2 is partially exposed and cannot retract completely, and the exposed parts of the two telescopic back rests 2 have the same length. Under this kind of state, this guiding ruler is the same with ordinary guiding ruler outward appearance and function completely, can not influence this guiding ruler and use as ordinary guiding ruler. When the telescopic back legs 2 extend out to the maximum, as shown in fig. 2, all the buckles 3 are clamped in the holes, and the extending lengths of the two telescopic back legs 2 are the same. In this state, the guiding ruler can simply stride over the obstacles such as keel and measure.
