Description

A kind of jaw planar survey chi

Technical field

This utility model relates to technical field of medical instruments, is specifically related to a kind of jaw planar survey chi.

Background technology

In curative activity, doctor sometimes needs to measure patient's jaw face size, and existing mode is adopted With some simple device measurings, its precision is the highest；According to complicated accurate device, then cost is huge, It is unfavorable for the development of medical industry.In order to solve this problem, State Intellectual Property Office was in 2015 08 month Within 19th, authorizing and disclosing notification number is CN 204562166 U, entitled " a kind of jaw face external pelivimetry of utility model Chi ", including left clamp bar and right clamp bar, inside lateral bend in the middle part of this left clamp bar and in the middle part of right clamp bar, and at curved surface Apex is hinged；Afterbody at left clamp bar is provided with the bevel protractor of arc, the tail of described right clamp bar Portion is provided with the cone facilitating reading.Although this mesognathy planar survey chi can measure jaw face easily, but its Structure is the most complicated, measures also the most inconvenient.

Utility model content

This utility model purpose is to provide a kind of jaw planar survey chi, and it can efficiently solve in background technology and be deposited Problem.

In order to solve the problem in the presence of background technology, it comprises the first clamp bar 1 and the second clamp bar 2, and this is years old Inside lateral bend in the middle part of one clamp bar 1 and in the middle part of the second clamp bar 2, and hinged at curved surface apex；? The afterbody of the first clamp bar 1 is provided with the bevel protractor 3 of arc, and the afterbody of the second described clamp bar 2 is provided with conveniently The cone 4 of reading, the outside of described first clamp bar 1 bottom is provided with link 5；The one of described second clamp bar 2 Side offers guide chute 6, is provided with the guide runner 7 with its clearance sliding fit in this guide chute 6, The other end of described guide runner 7 is fixing with attacker's ring 8 to be connected.

Owing to have employed above technical scheme, this utility model has the advantages that simple in construction, if Meter is reasonable, during use, by pulling attacker's ring open-angle i.e. between scalable the first clamp bar and the second clamp bar Degree, and the upper and lower scalable of attacker's ring, it is possible to measure jaw face easily, be arranged on the first clamp bar lower outside Link can also double as attacker's ring use, use during can held stationary, be greatly improved Security performance, and cheap for manufacturing cost, it is beneficial to promote.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model, below in conjunction with accompanying drawing, embodiment is briefly described.

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect Understand, below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment Scheme is clearly and completely described.

Referring to Fig. 1, this detailed description of the invention is to be achieved by the following technical solutions, and it comprises the first clamp bar 1 and second clamp bar 2, inside lateral bend in the middle part of this first clamp bar 1 and in the middle part of the second clamp bar 2, and on curved surface top At Dian hinged；Afterbody at the first clamp bar 1 is provided with the bevel protractor 3 of arc, the second described clamp bar The afterbody of 2 is provided with the cone 4 facilitating reading, and the outside of described first clamp bar 1 bottom is provided with link 5； The side of described second clamp bar 2 offers guide chute 6, is provided with and slides with its gap in this guide chute 6 The guide runner 7 coordinated, the other end of described guide runner 7 is fixing with attacker's ring 8 to be connected.

Owing to have employed above technical scheme, this detailed description of the invention has the advantages that simple in construction, Reasonable in design, during use, by pulling attacker's ring i.e. opening between scalable the first clamp bar and the second clamp bar Angle, and the upper and lower scalable of attacker's ring, it is possible to measure jaw face easily, be arranged on the first clamp bar lower outside Link can also double as attacker's ring use, use during can held stationary, be greatly improved Security performance, and cheap for manufacturing cost, it is beneficial to promote.

Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than right It limits；Although this utility model being described in detail with reference to previous embodiment, this area common It will be appreciated by the skilled person that the technical scheme described in foregoing embodiments still can be modified by it, Or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make corresponding skill The essence of art scheme departs from the spirit and scope of this utility model each embodiment technical scheme.
