Abstract
Provided is an intrauterine device disposing pipe external diameter detection apparatus, characterized by comprising a hollow pipe body having a circular hole, and a detecting over end and a detecting no-go end which are arranged inside the hollow pipe body, wherein the circular hole diameter of the detecting over end is the upper limit of the external diameter of the to-be-detected object; the length of the detecting over end is no less than the length of the to-be-detected object; and the circular hole diameter of the detecting no-go end is the lower limit of the external diameter of the to-be-detected object. The intrauterine device disposing pipe external diameter detection apparatus of the utility model allows the external diameter detection over all the points of the disposing pipe in the axial direction, ensures the rapid separation of the qualified products from the unqualified products, prevents the disposing pipes unable to meet the tolerance dimension requirements from entering the next working procedure, and ensures the product quality of the next working procedure. Compared with the prior art, the intrauterine device disposing pipe external diameter detection apparatus has the advantages of simple structure, rapid operation, accurate measurement, and the like.
Description
Technical field
The utility model relates to a kind of measurement instruments of inspection, specifically a kind of intrauterine device placing tube external diameter detection device.
Background technology
Existing most contraception device introducer primary clustering is the cylindrical disposed tubes of hollow, when the disposed tubes external diameter has determined directly that disposed tubes is used by Cervical ability and the moving resistance size that is mounted on the locating piece of disposed tubes outside.Therefore be necessary the external diameter of disposed tubes is detected.
In existing detection method, usually adopt vernier caliper or milscale that the external diameter of disposed tubes is measured.Because most disposed tubes are the cylindrical non-toxic plastic pipe of hollow, tube wall is thinner, in the process of measuring, when with above-mentioned survey instrument chucking disposed tubes, deformation easily occurs at direction of measurement and causes the measurement result out of true in its tube wall, and once can only measure the diameter of a location point of disposed tubes tube wall when measuring with above-mentioned survey instrument, and measure the diameter that the disposed tubes length direction has a few then wastes time and energy, easily make substandard product flow into next process, affect product quality.
Summary of the invention
The purpose of this utility model is intended to improve the weak point that prior art exists, and a kind of easy and simple to handle, intrauterine device placing tube external diameter detection device fast and effeciently is provided.
The utility model is achieved through the following technical solutions: a kind of intrauterine device placing tube external diameter detection device, characteristics are, it comprises round-meshed hollow body, be provided with in the hollow body and detected end and detected not-go-end, the Circularhole diameter that detected end is the external diameter upper limit of determinand, the length that detected end is not less than the length of determinand, and the Circularhole diameter that detects not-go-end is the external diameter lower limit of determinand.
In order to realize better goal of the invention, be provided with the transition coupling part detecting end and detect between the not-go-end, the transition coupling part is the transition of infundibulate annulus.
The utility model is the cavity tubular structure, when utilizing this device that the disposed tubes external diameter is detected, the testing result out of true that both can avoid tightening deformation and cause, can finish fast again simultaneously the external diameter that the whole axial length of disposed tubes is had a few detects, assurance certified products and unacceptable product are separated fast, the disposed tubes of avoiding not meeting the tolerance dimension requirement flows into next procedure, ensures the product quality of next procedure.Compared with the prior art, have the plurality of advantages such as simple in structure, swift to operate, that measurement is accurate.
Below in conjunction with drawings and Examples the utility model is done and to be explained.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 hollow body, 2 detected end, 3 transition coupling parts, 4 detect not-go-end.
Embodiment
Referring to Fig. 1, the utility model is a hollow tubular body structure, adopt the on-deformable material of hard to make, such as stainless steel, hard plastic material etc., profile can be square tube, pipe etc., through hole in the hollow body 1 is circular hole, hollow body 1 inner chamber is set to detect holds 2 and detect not-go-end 4 two parts, wherein, detecting the bore dia of holding 2 parts is the external diameter standard max of determinand (being the contraceptive disposed tubes), and its length is greater than the length that equals determinand, and the bore dia that detects not-go-end 4 parts is the external diameter standard min of determinand.
Principle of work:
When using this pick-up unit to measure the external diameter of disposed tubes, this device is vertically placed, detected and hold 2 upper, detect not-go-end 4 lower.Held 2 to put into from detecting disposed tubes to be measured, since detected hold 2 with the detection not-go-end 4 the aperture be respectively the bound that the disposed tubes normal diameter requires, and detected the length of holding 2 length to be not less than determinand, therefore, if disposed tubes can be under the effect of self gravitation, all submerge to detect and hold 2 and when detecting not-go-end 4 and do not come off, then the external diameter of this disposed tubes is specification product between the bound of external diameter standard-required; Hold 2 or can not submerge to detect fully and hold 2 if disposed tubes can not be put into to detect, then the external diameter of this disposed tubes is substandard product greater than the upper limit of external diameter standard-required; If this disposed tubes was held 2 by detecting, was deviate from from detecting not-go-end 4 again simultaneously, then the external diameter of this disposed tubes is less than the lower limit of external diameter standard-required, be similarly substandard product, thereby can realize the whole detection of disposed tubes is distinguished qualified and substandard product simultaneously rapidly, guarantee product quality.
In addition, held 2 and detect the transition coupling part 3 that infundibulate annulus intermediate shape can also be set between the not-go-end 4 detecting, this transition coupling part 3 will be detected and hold 2 and detect between the not-go-end 4 and be trimmed to rounding off, substandard product is passed through more easily, in order to avoid cause false retrieval undetected.
