Abstract
The utility model provides a vernier caliper which comprises a main ruler, a depth ruler, a vernier, an inner measuring jaw and an outer measuring jaw. The length of the two measuring jaws is 30%-60% of that of the main ruler, and the two measuring jaws are detachably connected to the main ruler. The length of the two measuring jaws is increased, so that the vernier caliper can measure sizes of work pieces which can not be measured by ordinary vernier calipers; and the two measuring jaws are detachably connected to the main ruler so that the flexibility of the vernier caliper is increased during using, a user can select whether the measuring jaws are required to be changed according to specific conditions to obtain accurate measuring values, application ranges of the vernier caliper are increased, and the most suitable vernier caliper can be used for each measuring.
Description
Technical field
The utility model relates to slide calliper rule field, particularly a kind of vernier caliper.
Background technology
Vernier caliper is a kind of measurer of measuring length, internal-and external diameter and the degree of depth, and it can measure portion be in length, internal-and external diameter and the degree of depth thereof of the workpiece of use state or test mode.But present vernier caliper, it can't measure disguised stronger workpiece; And in general, for more special professional domain, have more suitable vernier caliper relatively, common calliper can not be gathered the speciality of this special vernier caliper, measure comparatively accurately if think, may need vernier caliper more than, more suitable, this will cause the function limitation of single vernier caliper.This is the existing weak point of prior art.
The utility model content
Technical problem to be solved in the utility model is exactly for the existing deficiency of prior art, and a kind of vernier caliper technical scheme is provided, and the vernier caliper that this scheme provides can solve this technical problem effectively.
The technical scheme of employing of the present utility model is:
A kind of vernier caliper comprises main scale, pit gauge, vernier, trip bolt, interior measuring claw and external pelivimetry pawl, and described two measuring claw length are 30% ~ 60% of described main scale length, and described two measuring claw releasable connections are on main scale.
As the further restriction to the technical program, described releasable connection is for being threaded.
As the further restriction to the technical program, described releasable connection is that pin connects.
Compared with prior art, this utility model has the following advantages:
(1) increase the length of two measuring claws of vernier caliper, made this vernier caliper can measure the immeasurable workpiece size of conventional vernier caliper;
(2) pass through two measuring claw releasable connections on main scale, increased the flexibility ratio when this vernier caliper uses, the user can select whether to need to change measuring claw according to concrete condition, to obtain more accurate measured value, thereby having increased the scope on probation of vernier caliper, is all the measurement of carrying out with most suitable vernier caliper to guarantee each measurement.
This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Description of drawings
Fig. 1 is the structural representation of an embodiment of vernier caliper described in the utility model;
Fig. 2 is the structural representation that vernier caliper shown in Figure 1 is pulled down one of them external pelivimetry pawl;
Wherein: 1, main scale, 2, pit gauge, 3, vernier, 4, trip bolt, 5, interior measuring claw, 6, the external pelivimetry pawl, 7, pin, 8, pin-and-hole.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth, but the utility model is not limited to following embodiment.
In addition, the structural representation that vernier caliper shown in Figure 1 is pulled down one of them external pelivimetry pawl as shown in Figure 2, and as shown in Figure 2, in embodiment of the present utility model, two measuring claws use pin to connect the pin-and-hole 8 of described main scale 1 and described two measuring claws, thereby guarantee the stability of this vernier caliper itself.
Vernier caliper described in the utility model has increased the length of two measuring claw, thereby has enlarged the measurement range of vernier caliper, can measure the immeasurable workpiece size of conventional vernier caliper.
Two measuring claw releasable connections of vernier caliper described in the utility model are on main scale 1, make when being necessary, can change more suitable measuring claw according to needs, thereby make this vernier caliper on probation wider, accomplish to use corresponding measuring claw to measure different classes of workpiece; And dismountable characteristics also are convenient to it and are deposited.
As the further restriction to the technical program, described releasable connection is for being threaded.
In addition, according to the actual needs, can also be set to folding measuring claw by two measuring claws, so as realistic needs, the usable range of expansion vernier caliper.
the above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model with preferred embodiment openly as above, yet, be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, certainly can utilize the technology contents of announcement to make a little change or modification, become the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
