Abstract
The utility model discloses a special calliper gauge used for measuring the size of each position of a human body. The utility model comprises a main ruler provided with a static quantity claw and a vernier which is provided with a movable quantity claw and can slide along the main ruler. The static quantity claw and the movable quantity claw can be oppositely opened and closed. The static quantity claw and the movable quantity claw respectively form an arc shape. Symmetrical and involutive gaps of the static quantity claw and the movable quantity claw respectively form a spindle shape. The measuring claws of the utility model respectively form an arc shape, which is suitable for measuring the size of a position of a human body. Simultaneously, the utility model has the advantages of simple structure, small volume, light weight, low cost, convenient carry and operation, etc.
Description
Technical field
This utility model belongs to the medical research instrument, relates in particular to a kind of special-purpose calliper that is used for measuring partes corporis humani position size.
Background technology
In human medical research field, anatomy field, the size that often needs to measure the partes corporis humani position with study, malformation correction or the diagnosis state of an illness.But never have for a long time, the instrument of special measurement partes corporis humani position.General way is to measure with general vernier gauge, but plain calliper gauge only is fit to measure the size of regular shapes such as general axle, hole, because human body, out-of-shape such as head, the shape of its measuring jaw is not suitable for, often need bring operational trouble so just for measurement human body size, and can make the error of measurement bigger by means of cushion block.
Summary of the invention
The purpose of this utility model is to provide the special-purpose calliper of a kind of partes corporis humani of measurement position size.
For achieving the above object, the vernier that can slide along main scale that this utility model comprises the main scale that has quiet measuring jaw and has the momentum pawl, quiet measuring jaw and momentum pawl can relative foldings, and described quiet measuring jaw and momentum pawl are curved, and quiet measuring jaw and momentum pawl symmetry, involutory slit is spindle.
Above-mentioned quiet measuring jaw and main scale, momentum pawl and vernier form and removably connect; Retaining mechanism is set on the vernier.
Above-mentioned retaining mechanism is to have screwed hole on the vernier, and the screwed hole setting can compress the trip bolt of main scale end face.
Above-mentioned main scale can be provided with position-limit mechanism; Position-limit mechanism can be the slide block that is fixed on the block of main scale termination or has retaining mechanism, can slide along main scale.On the main scale of the present utility model digital display device can also be set.
This utility model since measuring jaw be shaped as arc, be fit to measure partes corporis humani position size, also have simultaneously simple in structure, volume is little, in light weight, cost is low, be easy to carry and advantage such as operation.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment 1;
Fig. 2 is the structural representation of this utility model embodiment 2.
The specific embodiment
This utility model embodiment 1 structure as shown in Figure 1, it mainly is made of the vernier 3 that has quiet measuring jaw 2 main scales 1 and have a momentum pawl 4, quiet measuring jaw 2 and momentum pawl 4 symmetries, involutory slit is spindle.Its camber line should match with people's buccal particularly; The cross section of strip main scale 1 is a rectangle, and its front has graduation mark and sign; The cross sectional shape of vernier 3 becomes channel steel shape, and its inside groove size cooperates with the main part of main scale 1, and can slide along main scale 1 length direction; The scale of main scale 1 indicates 250 little lattice from left to right, and each little lattice width is 1 millimeter; 50 little lattice are arranged on the vernier, and every little lattice width is 0.98 millimeter; The scale of main scale 1 and vernier 3 all is to be zero point with the starting line, when momentum pawl 4 contacts with the bayonet socket of quiet measuring jaw 2, vernier 3 graduated zero point line overlap with main scale 1 graduated zero point line, are not difficult to find out, this moment, the graduated finishing line of vernier 3 overlapped with main scale 1 graduated 49 millimeters lines.On the vernier 3 retaining mechanism is set, it is to have screwed hole on vernier 3, setting can compress the trip bolt 5 of main scale 1 end face in the screwed hole, turns clockwise that it can play the effect that vernier 3 is locked at a certain position on the main scale 1, is rotated counterclockwise and then can makes vernier 3 slip that affranchises.
Be example to measure child's skull width below, the operating process of present embodiment is described.
During actual the use, earlier vernier 3 and momentum pawl 4 are slided into the side away from quiet measuring jaw 2, hand-held calliper makes child's head about position intermediate between momentum pawl 4 and quiet measuring jaw 2; Slowly moving cursor 3 and momentum pawl 4 slide to quiet measuring jaw 2, and mobile simultaneously calliper main scale 1 makes quiet measuring jaw 2 draw close to child's head one side; Finally make momentum pawl 4, quiet measuring jaw 2 be attached on two buccals of child respectively and interior profile and child's buccal of measuring jaw match; Read the numerical value of calliper and promptly measured child's skull width this moment.The precision of present embodiment is 0.02mm.
Consider that because the shape of partes corporis humani position is inequality above-mentioned quiet measuring jaw 2 forms with vernier 3 with main scale 1, momentum pawl 4 and removably connects, such as adopting bolt or screw that quiet measuring jaw 2 is fixed on the main scale 1, momentum pawl 4 is fixed on the vernier 3.This known technology that is detachably connected as is seldom given unnecessary details at this.Like this, the foot-measuring that just can change other shape has at any time been realized the many usefulness of a chi to measure the size at other position of human body, has increased motility of the present utility model.
In order to prevent that vernier 3 and momentum pawl 4 from skidding off main scale 1, in the termination of main scale 1 position-limit mechanism 6 is set, it can be a fixed stop such on the common slide calliper rule, it also can be structure as shown in Figure 1, promptly be have with vernier 3 on the slide block that can slide along main scale 1 of identical retaining mechanism, relatively it can realize arbitrarily determining spacing position with the former.
Reading plotter can be directly to read, and also numeric display unit can be set on main scale.Increasing the digital display device reading on the slide calliper rule is prior art.Number of patent application is to disclose a kind of electronic cursor slide calliper rule in the ublic specification of application of 97182164.X.
Fig. 2 has reflected the basic structure of this utility model embodiment 2, as different from Example 1, has digital display screen 7 on the main scale 1, and its precision can be 0.01mm.
This shows, this utility model is simple in structure-can be only to common vernier gauge measuring jaw change, easy and simple to handle-artificial hand rule that hold operate, can directly read numerical value.
