Abstract
The invention relates to a tool for detecting apertures, which comprises a handle (1) and a measuring head (2). The upper end of the handle (1) is directly connected with the lower end of the measuring head (2), and a plurality of round steel segments with equal length are connected sequentially to form the measuring head (2). The diameters of the series of the round steel segments sequentially increase from top to bottom, and the measuring values are marked on corresponding round steel segments. The tool for detecting apertures can be directly used in factories or on construction sites; and the measuring head is inserted into a hole to be detected, if the hole to be detected fits with a certain segment of the round steels, then the aperture value can be directly read from the diameter numbers of the round steel segment. Apertures of a bolt group different in aperture can be detected in a batch manner quickly and conveniently by the aid of the tool for detecting apertures.
Description
Technical field
The present invention relates to a kind of testing tool, relate in particular to a kind of aperture testing tool.
Background technology
Some structures of in the factory or working-yard or equipment adopt a large amount of bolts to connect usually, and bolt model commonly used has M10, M12, M16, M18, M20, M24, M30.When detecting the bolt aperture, if use general measurer such as tape measure, vernier caliper, reading need be estimated and reads and need to measure repeatedly to calculate to average; Whether qualified recheck measured value; Work is very loaded down with trivial details, and the bolt hole crowd that especially a large amount of pore sizes differ detects more complicated; Need take the plenty of time, not only influence work efficiency and also possibly influence construction speed.
Summary of the invention
In order to solve the problems of the technologies described above; The present invention provides a kind of simple in structure, aperture testing tool conveniently; It is characterized in that comprising handle and measuring head, the handle upper end directly links to each other with the measuring head lower end, and measuring head is connected to form by some equal length round steel sections in order; These a series of round steel sections diameter from top to bottom increases successively, and is marked on these measured values on the corresponding round steel section.
Beneficial effect of the present invention is: directly use the present invention to be inserted into measuring head in the hole to be checked in factory or working-yard; Hole to be measured and certain section round steel coincide; Just can be directly diameter value on this round steel section read corresponding aperture value; Especially the batch detection pore size differ bolt crowd aperture the time very efficient and convenient, save Measuring Time greatly, increase work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
According to Fig. 1 the present invention is done further explain.
The present invention is processed by the round steel of one section diameter 36mm length 350mm; Comprise handle 1 and measuring head 2; Measuring head is divided into 7 equal length round steel sections; Every segment length is 30mm, and these 7 round steel sections diameter from top to bottom is respectively the measured value in bolt M10 commonly used, M12, M16, M18, M20, M24, M30 aperture.When measuring the aperture in factory or working-yard, directly use the present invention to be inserted into measuring head in the hole to be checked, hole to be measured coincide with certain section round steel, just can be directly diameter value on this round steel section read the aperture value of correspondence.
