Description
Technical field
The present invention relates to a kind of three-pawl type diameter measuring device.
Background technology
Three-pawl type diameter measuring device of the prior art is contacted using the end of its three connecting rods with disc,
Three ends form three summits of triangle, and the circumscribed circle diameter of triangle is the straight of measured disc
Footpath, because user can more conveniently measure the distance between three ends, thus can more conveniently it pass through
Mathematical knowledge reads out the diameter of disc, but three-pawl type diameter measuring device of the prior art is measurable
Scope is smaller, and end is easily worn, thus service life is shorter.
The content of the invention
The present invention mainly solves the technical problem present in prior art, a kind of with three the so as to provide
One connecting rod and three the second connecting rods, the second connecting rod form adjustable articulated structure with head rod,
Thus measurement range is larger, also with rotating roller, can be rotated when being contacted with disc, thus is not easy to be ground
Damage, the longer three-pawl type diameter measuring device of service life.
The present invention solves the technical problem in the presence of prior art by following technical proposals：
A kind of three-pawl type diameter measuring device, including a connecting plate and three head rods, described connection
The edge of plate is evenly arranged with three connecting holes, and one end of described head rod is cut with scissors with described connecting hole
Connect, described three-pawl type diameter measuring device also includes three the second connecting rods and three rotating rollers, described
One end of second connecting rod and the other end of described head rod form adjustable company of rotation by bolt
Binding structure, the other end of the second described connecting rod and the center of one end of described rotating roller are mutually perpendicular to cloth
Put and form rotation connection structure.
As preferred embodiments of the present invention, the other end of described rotating roller is provided centrally with a cone.
The present invention three-pawl type diameter measuring device the advantages of be：With three head rods and three second
Connecting rod, the second connecting rod forms adjustable articulated structure with head rod, thus measurement range is larger,
Rotating roller is also carried, can be rotated when being contacted with disc, thus is not easy to be worn, service life is longer.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to implementing
The required accompanying drawing used is briefly described in example or description of the prior art, it should be apparent that, describe below
In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative work, other accompanying drawings can also be obtained according to these accompanying drawings.

Embodiment
The preferred embodiments of the present invention are described in detail below, so that advantages and features of the invention can be more
It is easy to be readily appreciated by one skilled in the art, so as to make protection scope of the present invention on apparent clear and definite boundary
It is fixed.
The present invention three-pawl type diameter measuring device the advantages of be：With three head rods and three second
Connecting rod, the second connecting rod forms adjustable articulated structure with head rod, thus measurement range is larger,
Rotating roller is also carried, can be rotated when being contacted with disc, thus is not easy to be worn, service life is longer.
As shown in figure 1, a kind of three-pawl type diameter measuring device, including 1, three head rod of a connecting plate
2nd, three the second connecting rods 3 and three rotating rollers 4, the edge of the connecting plate 1 are evenly arranged with three connections
Hole, one end of the head rod 2 are hinged with the connecting hole, one end of second connecting rod 3 with this first
The other end of connecting rod 2 forms adjustable articulated structure by bolt, and this structure allows user larger
The length for adjusting the head rod 2 and the claw structure of second connecting rod 3 composition of scope, thus can
The diameter range of measurement is also larger, the other end of second connecting rod 3 and the center of one end of the rotating roller 4
It is mutually perpendicular to arrange and form rotation connection structure, can be with when this structure makes the rotating roller 4 be contacted with disc
Rotate, so as to avoid being worn, service life is longer.When measuring diameter, it is only necessary to first measure three and turn
The distance between central shaft of dynamic roller 4, calculates its circumscribed circle diameter, along with the diameter of the rotating roller 4
As it is measured the diameter of disc.
As shown in Fig. 2 the other end of the rotating roller 4 is provided centrally with a cone 31.This structure, can
To facilitate user more accurately to find out the center of the rotating roller 4, so as to more accurately more easily measure
The distance between central shaft of rotating roller 4.
It is only the mentality of designing of some embodiments of the present invention above, in the case where system allows, this
Invention can expand to while external more functional modules, so as to extend its function to greatest extent.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited to
This, any change or replacement expected without creative work, should all cover in protection scope of the present invention
Within.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
