Description
Technical field
The utility model relates to survey instrument technical field, and in particular, it relates to a kind of vernier caliper.
Background technology
Vernier caliper is a kind of measurer of measuring length, internal-and external diameter, the degree of depth.Vernier caliper is by main scale and be attached to slidable vernier two parts on main scale and form.Main scale generally be take millimeter as unit, has 10,20 or 50 lattices on vernier, and according to the difference of lattice, vernier caliper can be divided into extremely spends vernier caliper, 20 minutes degree vernier calipers, 50 minutes degree lattice vernier calipers etc.On the main scale of vernier caliper and vernier, having two secondary movable measuring jaws, is respectively interior measuring claw and external pelivimetry pawl, and interior measuring claw is commonly used to measure internal diameter, and external pelivimetry pawl is commonly used to measure length and external diameter.The function of Here it is common calliper.But industrial have a numerous parts, and machine intimate part cannot take out, and the measuring claw of vernier caliper does not reach and measures body or housing, and because of measured object limited space, relative dimensions is to measure it with existing vernier caliper.Chinese utility model patent number is a kind of vernier caliper of 201120409648.6, has a pair of external pelivimetry pawl; Between described external pelivimetry pawl, be provided with dorsad the fixed cover of " U " shape; Described fixed cover is located and is arranged on external pelivimetry pawl by securing member, is provided with in opposite directions columniform auxiliary block between two fixed covers; Fixed cover and auxiliary block are formed in one.Because this auxiliary block and fixed cover are integrated, inconvenient auxiliary block is changed and can not be carried out dismounting to it, also be inconvenient to measure operation, the design of the fixed cover fixed position of " U " shape, dwindled the usable range of vernier caliper, still be subject to a certain extent the restriction in measured object space, the size that need to put in inside parts to some still cannot be measured.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of measuring jaw length scalable and adjustable vernier caliper, this vernier caliper can be used for the measured object of different size size, and can stretch into measured object internal measurement, has expanded the usable range of vernier caliper.
For achieving the above object, the utility model provides following technical scheme: a kind of vernier caliper, comprise main scale and be slidably fitted in the vernier on main scale, described vernier is provided with right measuring jaw, on described main scale, be installed with left measuring jaw, described left measuring jaw and right measuring jaw include fixed cover and are axially located in the sliding bar in fixed cover, and described sliding bar is provided with elastic component, and described fixed cover is provided with some through holes that wear for elastic component.
By adopting technique scheme, while using vernier caliper, with left measuring jaw and right measuring jaw, clamp measured object, when the width of measured object is longer, sliding bar can be carried out in fixed cover axially relative to fixed cover opposite side direction, moving, elastic component generation deformation on sliding bar is compressed between sliding bar and fixed cover, until the length of left measuring jaw and the length of right measuring jaw are while enough measuring measured object, elastic component wore through hole, elastic component resets, sliding bar is fixed in fixed cover, stops occurring the change of relative displacement between sliding bar and fixed cover; When the width of measured object not length be that the length of left measuring jaw and the length of right measuring jaw are when long, sliding bar can be moved the direction towards corresponding fixed cover one side, elastic component is separated with through hole, again be compressed between sliding bar and fixed cover until elastic component wore next through hole, because the quantity of through hole is set to several, by the length of the left measuring jaw of this structure and the adjustable in length of right measuring jaw, this vernier caliper can be used for the measured object of different size size, and can stretch into measured object internal measurement, expand the usable range of vernier caliper.
The utility model is further set to: the relative fixed cover other end of described sliding bar is connected with auxiliary rod.
By adopting technique scheme, when left measuring jaw and right measuring jaw need to stretch into measured object inside and carry out dimensional measurement, the inner body that can clamp by the auxiliary rod of both sides measured object accurately measures, if while not needing to use auxiliary rod, rotate auxiliary rod and overlap and can measure with sliding bar, and do not take up room.
The utility model is further set to: described auxiliary rod is connected with sliding bar bearing pin.
By adopting technique scheme, auxiliary rod is connected and can on sliding bar, be carried out free rotation by bearing pin, when needs are used auxiliary rod to measure, makes to be vertical setting between auxiliary rod and sliding bar, is convenient for measuring; When not using auxiliary rod, rotate auxiliary rod auxiliary rod is overlapped on sliding bar, facilitate vernier caliper for the use of other measured objects.
The utility model is further set to: described sliding bar is provided with pin, and described auxiliary rod is fixedly connected with sliding bar by pin.
By adopting technique scheme, when needs are used auxiliary rod to measure, rotate auxiliary rod, make to be vertical setting between auxiliary rod and sliding bar, by pin, auxiliary rod not only can be fixedly mounted on sliding bar also can carry out free rotation on sliding bar, when not using auxiliary rod, rotate auxiliary rod auxiliary rod is overlapped on sliding bar, do not need auxiliary rod to disassemble, flexible and convenient to use.
The utility model is further set to: described sliding bar and fixed cover are slidably matched and fixed cover and sliding bar shape, size are all suitable.
By adopting technique scheme, fixed cover is set on sliding bar and the inwall of fixed cover and the laminating of the outer wall of sliding bar, and the contact area between fixed cover and sliding bar is large, pull after sliding bar, sliding bar can be in fixed cover Stable sliding, can not shake, stability is strong.
The utility model is further set to: the making material of described main scale and vernier is stainless steel.
By adopting technique scheme, stainless steel material structural strength is good, antiseptic property is good, and the main scale made from stainless steel and cursor structure intensity are good, even that vernier caliper is long-term use in the situation that is also not fragile or fracture, and anticorrosion, good antirust property, the long service life of vernier caliper.
The utlity model has following advantage: the length of left measuring jaw and right measuring jaw all length scalable and left measuring jaw and right measuring jaw is all adjustable, this vernier caliper can be used for the measured object of different size size, and can stretch into measured object internal measurement, expand the usable range of vernier caliper.
