Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
As shown in Figure 1, the utility model provides a kind of pain nerve detector, including with lower component：For preventing from visiting
The probe protection set 1 of pin bending damage, with permanent magnet 201 and the magnet assembly of probe sheath 202 2, locating part 3, with flat
The probe assembly 4 and outer sleeve 5 of head probe 401 and probe base 402.
Fig. 2-Fig. 9 respectively describes the structure of various components：
Magnet assembly shown in Fig. 2, Fig. 3 is made of permanent magnet 201 and probe sheath 202, and wherein 201 center of permanent magnet is set
First through hole 204 is equipped with, its tack probe 401 being dimensioned in probe assembly 4 passes through.The outside of permanent magnet 201 is additionally provided with
External screw thread 203, coordinates with the internal thread 502 on outer sleeve 5, adjusts relative position of the outer sleeve 5 with permanent magnet 201.Probe
Sheath 202 is hollow tubular sheath, is integrated with 201 center vertical connection of permanent magnet, 202 internal coat of probe sheath has lubrication
Oil, for reducing the resistance during activity of probe 401.
Locating part 3 shown in Fig. 4, Fig. 5 is a thin hard gasket of annular, can screw thread or glue even by way of same overcoat
Cylinder 5 is fixedly connected, for limiting stroke of the probe base 402 in outer sleeve 5.
Component shown in Fig. 6, Fig. 7 is the tack probe 401 and probe base 402 of drawing pin sample, and tack probe 401 is hard
Nonmagnetic substance (plastics, aluminium alloy etc.) made from elongate cylinder.The diameter of tack probe just can be to pass through sheath 202
Sheath endoporus and first through hole 204.Probe base 402 is thin discs made of iron, and tack probe 401 is vertically fixedly connected on probe
402 center of base.
Component shown in Fig. 8, Fig. 9 is outer sleeve 5, is cup shaped transparent sleeve, is made of PMMA organic plastics, has one
Determine intensity, internal thread 502 is provided with the inside of sleeve-port, and the corresponding sleeve lateral wall of internal thread 502 has graduation mark 503, sign
Corresponding pressure value, the external screw thread 203 on magnet assembly 2 coordinate with the internal thread 502, can screw in outer sleeve 5, and can basis
The pressure value needed adjusts screw-in depth.Probe base 402 can slide in outer sleeve 5, its stroke is by sleeve bottom and locating part 3
Position is limited, and the second through hole 501 is provided with sleeve bottom barrel 504, and the second through hole 501 is stomata, is mainly used for when spy
When pin base 402 slides in outer sleeve 5, if the air-tightness coordinated between the two is preferable, additional stomata is needed with balance external
Air pressure inside and outside sleeve 5.
The installation steps of each component are as follows：
Probe assembly 4 to be filled in inside outer sleeve 5 first, locating part 3 is rotated to the bosom of 5 internal thread 502 of outer sleeve,
Gluing is fixed；Magnet assembly 2 is then inserted in probe and is screwed in outer sleeve 5；Protective case 1 is finally directly sleeved on outer sleeve 5
Outside, to protect the exposed parts of each component.
As shown in Figure 10, position of the permanent magnet 201 in outer sleeve 5 in the pain nerve detector provided in the present embodiment
Putting can be by threaded adjusting, and the position of probe base 402 is limited by the locating part 3 being fixedly connected with outer sleeve 5, therefore forever
The minimum range (i.e. maximum suction position) that magnet 201 attracts each other with probe base 402, can be changed by rotating screw thread.
Magnet can be attracted each other by magnetic force, and the suction when closest is maximum, and with the increase of standoff distance, suction also declines rapidly
Subtract.Detector can be designed using the attracting principle of the same sex, when the pressure that detector applies detected person reaches two pieces of permanent magnets
Suction maximum after, once external force exceeds the suction between magnet, be just subjected to displacement between magnet, standoff distance increase, mutually inhales
Power declines；Detect pin at the same time to be retracted rapidly, to the rapid pressure drop of detected person, in whole detection process, to detected person
The maximum pressure of application is the suction of two pieces of permanent magnet minimum distances.Can be by adjusting the minimum of magnet apart in the present embodiment
Distance, to control and quantify the maximum suction, so as to limit the maximum pressure that can apply to detected person.In addition, pin
Point is designed as tack, therefore contact area is also fixed, and then secures maximum pressure so that measurement result more standard
Change, improve detection efficiency and accuracy rate
As shown in Figure 10, a length of L1 in outer sleeve 5,5 inner bottom surface of outer sleeve to permanent magnet 201 is close to 3 side of locating part
The distance of bottom surface is L2, and the length of flat probe 401 adds the thickness of probe base 402 to be L3.Make L1 ＞ L3 ＞ L2, it is ensured that flat
Bottom probe 401 can be completely retracting in outer sleeve 5 both will not dieback, will not fall completely within outer sleeve 5 and cannot reset.Should
Design prevents pressure skyrockets from stabbing detected person, and then ensure that the security of device.In addition, when needle point leaves detected person's skin
After skin, therefore the suction of permanent magnet 201, tack probe 401 can still automatically reset, to be detected next time.
The application method of above-mentioned pain nerve detector is additionally provided in the present embodiment, is included the following steps：
1st, protective cap is removed, exposes probe；
2nd, the scale that rotation adjustment permanent magnet extremely needs, setup pressure value；
3rd, detector pen body is clutched, probe is vertically touched to tested measuring point surface；
4th, exert oneself Pen-down detection device, until probe produce retracting action, lift detector rapidly；
5th, detector probe automatically resets, and completes one-time detection.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, all should be in the protection domain being defined in the patent claims.
