Description
Technical Field
The utility model relates to door and window construction, in particular to a door and window opening standard inspection ruler with high measurement precision and high measurement efficiency.
Background
The conventional method for measuring the dimension of the hole is that the clearance width is measured by using a meter ruler, the height is measured by using the meter ruler, the square is measured by using an angle square, the existing angle square has shorter length and larger measurement error, and the verticality is measured by matching a line weight with the meter ruler; whether the measurement of an entrance to a cave is qualified needs to use three measuring tools to measure 6 chi, and the process is tedious and low in efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems, and provides the standard inspection ruler for the door and window openings, which has high measurement precision and high measurement efficiency.
The utility model solves the problems and adopts the technical scheme that:
the utility model provides a door and window entrance to a cave standard inspection chi, includes the ruler, and the ruler end to end connects gradually into rectangular frame, and the vacuole spirit level sets up respectively on four angles of rectangular frame that constitute by the ruler, and the ruler is equallyd divide for interior chi and outer chi, and interior chi all sets up the inside constitution extending structure of chi outside, has all drawn the scale mark on interior chi and the outer chi.
Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:
the rectangular frame structure formed by adjusting the telescopic ruler is attached to the edge of the door and window opening, the net width and the net height of the door and window opening can be accurately measured according to the reading on the ruler, and the measurement is convenient, fast and accurate.
Secondly, the adjustable ruler has a large adjusting range and a wide application range through the telescopic structure of the ruler.
Whether four right angles of the rectangular frame formed by the observation ruler are attached to corners of the door and window openings or not reflects the squareness of the door and window openings directly, and angle measurement is accurate, direct and convenient.
And fourthly, the levelness and the verticality of the door and window opening are confirmed by observing the vacuole gradienter, and the measurement is rapid and visual.
The device measures net width, net height, squareness, levelness and verticality at one time, has high integration degree, can confirm whether the door and window opening is qualified or not only by measuring once, and saves labor.
The device has simple structure and convenient manufacture and use.
Preferably, the further technical scheme of the utility model is as follows:
the side surfaces of the outer ruler are provided with through holes, and fixing knobs are arranged inside the through holes; the extension length of the inner ruler is fixed.
Drawings
FIG. 1 is a schematic diagram of an expanded configuration of an embodiment of the present invention;
FIG. 2 is a schematic view of a closed configuration of an embodiment of the present invention;
FIG. 3 is a schematic diagram of a bubble level according to an embodiment of the present invention;
fig. 4 is a schematic structural diagram of a fixing knob according to an embodiment of the present invention.
In the figure: a vacuole level 1; an outer ruler 2; a fixed knob 3; an inner ruler 4.
The specific implementation mode is as follows:
the utility model will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the utility model.
Referring to fig. 1 to 4, a standard inspection chi of door and window entrance to a cave, including the ruler, the material of ruler is the aluminum alloy, the ruler end to end connects gradually into rectangular frame, four angles of rectangular frame are standard 90 jiaos and consolidate the processing, vacuole spirit level 1 is installed respectively on four angles of the rectangular frame who comprises the ruler, the ruler is equallyd divide into interior chi 4 and outer chi 2, interior chi 4 all installs the inside constitution extending structure at outer chi 2, accommodation is 700mm-2200mm, all be painted standard scale mark on interior chi 4 and the outer chi 2, can the precision measurement distance, two through-holes have all been seted up to the side of outer chi 2, fixed knob 3 is all installed to the inside of through-hole, fixed interior chi 4's the extension length, and then fixed ruler overall length.
When the inspection tool is used, the design size of a door and window hole to be inspected on a drawing is checked, the fixing knob 3 is unscrewed, the inner ruler 4 is pulled out to the standard length on the drawing, then the fixing knob 3 is screwed down, the standard inspection ruler for the door and window hole is placed at the door and window hole to be inspected, whether the standard inspection ruler for the door and window hole can be placed is observed, if the standard inspection ruler for the door and window hole can be placed, the door and window hole is qualified, if the standard inspection ruler for the door and window hole cannot be placed, the door and window hole is unqualified, the door and window cannot be installed, and the inspection tool needs to be rectified and modified; after the door and window opening is placed, the standard inspection ruler of the door and window opening is leveled according to the vacuole level meter 1, the squareness deviation of each edge and corner is observed, the inspection result is qualified if the deviation value is within the standard allowable range, the drawing design is met, and the inspection result is unqualified if the deviation value is greater than the standard requirement, and the correction is needed.
The utility model can accurately measure the net width and the net height of the door and window opening according to the reading on the ruler by fitting the rectangular frame structure formed by the adjustable ruler to the edge of the door and window opening, the measurement is convenient, fast and accurate, the adjustable ruler has the advantages that the adjustable ruler has a large adjusting range and a wide application range, the squareness of the door and window openings can be visually embodied by observing whether the four right angles of the rectangular frame formed by the ruler are attached to the corners of the door and window openings, the angle measurement is accurate, visual and convenient, confirm the levelness and the straightness that hangs down of door and window entrance to a cave through observing vacuole spirit level 1, it is swift directly perceived to measure, and the device once only measures net width, net height, squareness, levelness and the straightness that hangs down, and the integration degree is high, only needs to measure once just can confirm whether door and window entrance to a cave is qualified, saves the manual work, and device simple structure makes and convenient to use.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
