Abstract
The utility model provides a meter pen clamp. Two meter pens can be mounted on the meter pen clamp so that the meter pens can be operated by one hand, the distance between the two meter pens can be adjusted, and the two meter pens can be also separated from each other and used independently. The meter pen clamp is characterized in that a first meter pen clip is fixedly connected with a first member of a revolute pair, a second meter pen clip is fixedly connected with a second member of the revolute pair, an adjusting bolt penetrates through a first member screw hole in the first member of the revolute pair and a second member screw hole in the second member of the revolute pair, and a nut is fixed on the adjusting bolt. The first and second meter pen clips can rotate around the revolute pair which takes the adjusting bolt as the center, the meter pens are respectively connected and fixed with the meter pen clips via elastic force, and the meter pen clips are rotated to drive rotation of the meter pens and further adjust the distance between probes of the two meter pens. The adjusting bolt and nut can be adjusted to adjust the frictional force between the members of the revolute pair, thereby satisfying different test requirements. The meter pens can be conveniently mounted on the meter pen clips or removed from the meter pen clips due to elastic deformation of the meter pen clips, thereby satisfying different test requirements.
Description
Technical field
The present invention relates to a kind of test pencil of electronic test instrument, in particular for a kind of test pencil fixture of clamping test pencil.
Background technology
Present widely used multimeter, has two test pencils, could adapt to different measuring distances with two manual manipulations, to use, makes troubles.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of test pencil fixture, and two test pencils are held on test pencil fixture, can do measurement operation by one hand, and can regulate the distance of two test pencils, also can unload from test pencil fixture, split into two independently test pencil work.
The technical scheme that the utility model adopts is, a kind of test pencil fixture, comprise the first test pencil folder, the second test pencil folder, revolute pair the first member, revolute pair second component, adjusting bolt, nut, the first member screw, second component screw, described the first test pencil folder is fixedly connected with described revolute pair the first member, described the second test pencil folder is fixedly connected with described revolute pair second component, described the first member screw is positioned on described revolute pair the first member, described second component screw is positioned on described revolute pair second component, described adjusting bolt is through described the first member screw and described second component screw, described nut is fixed in described adjusting bolt, described the first test pencil folder and described the second test pencil folder can rotate around described adjusting bolt.Also comprise hand button, one of described adjusting bolt head and described nut are fixed in hand button.The elastic force that test pencil presss from both sides after distortion by test pencil is connected and fixed on test pencil fixture, thereby the rotation of test pencil folder drives the rotation of test pencil to regulate the distance of probe on two test pencils.Regulate adjusting bolt and nut, can regulate the pressure between two revolute pair members, thereby regulate the friction force of rotating between submember, to adapt to different test requests.The elastic deformation that test pencil presss from both sides by test pencil, can be installed to easily test pencil folder and above or from test pencil folder take off, to adapt to different test requests.Adjusting bolt head or nut are fixed in hand button, and regulating friction force is to turn hand button, makes to regulate more convenient.

1. first probes in figure, 2. the second probe, 3. the first test pencil, 4. the second test pencil, 5. the first test pencil folder, 6. the second test pencil presss from both sides, 7. revolute pair the first member, 8. revolute pair second component, 9. adjusting bolt, 10. nut, 11. revolute pairs, 12. first member screws, 13. second component screws, 14. hand buttons, when 15. installations or taking-up test pencil, the first test pencil presss from both sides 5 shapes, and during 16. clamping test pencil, the first test pencil presss from both sides 5 shapes, and under 17. free states, the first test pencil presss from both sides 5 shapes, under 18. free states, the first test pencil presss from both sides 5 diameters, 19. adjusting bolt heads.
Embodiment
Fig. 1 is embodiment of the present utility model, and Fig. 5 is the A-A sectional view of Fig. 1, to better understand the present embodiment.In the drawings, the first probe 1 is fixedly connected with the first test pencil 3, the first test pencil folder 5 is fixedly connected with the first test pencil 3 by elastic force, the first test pencil folder 5 is fixedly connected with revolute pair the first member 7, the second probe 2 is fixedly connected with the second test pencil 4, the second test pencil folder 6 is fixedly connected with the second test pencil 4 by elastic force, the second test pencil folder 6 is fixedly connected with revolute pair second component 8, and adjusting bolt 9 is connected with nut 10 with the second component screw 13 on revolute pair second component 8 through the first member screw 12 on revolute pair the first member 7 again.First test pencil folder the 5 and second test pencil folder 6 can rotate around the revolute pair 11 centered by adjusting bolt 9, thereby regulates the distance between the first probe 1 and the second probe 2.Regulate the tightness of adjusting bolt 9 and nut 10, can regulate the pressure of revolute pair the first member 7 and revolute pair second component 9, thereby change the friction force between revolute pair the first member 7 and revolute pair second component 9, to adapt to different test requests.The little test that is applicable to often change measuring distance of friction force, friction force is applicable to greatly the test of fixing test distance.Grasp test pencil fixture, the first test pencil 3 to B direction firmly, the first test pencil folder 5 produces elastic deformation, makes the first test pencil 3 depart from the constraint of the first test pencil folder 5, is independent of outside test pencil fixture and works, grasp test pencil folder, the second test pencil 4 to C direction firmly, the second test pencil folder 6 produces elastic deformation, makes the second test pencil 4 depart from the constraint of the second test pencil folder 6, be independent of outside test pencil fixture and worked, completed the function of independent test pencil.Same mode, exerts oneself round about, test pencil independently can be installed on test pencil folder.
In accompanying drawing 2, that test pencil is clipped in free state, clamping test pencil state, elastic deformation schematic diagram when installing or taking out test pencil state, the first test pencil folder 5 is fixedly connected with revolute pair the first member 7, when installing or take out test pencil, the shape of the first test pencil folder 5 is as shown in 15, and the shape of clamping test pencil the first test pencil folder 5 is as shown in 16, and during free state, the first test pencil folder shape is as shown in 17.Test pencil folder diameter is less than and is held test pencil, general approximately little 1-3 millimeter, and when the first test pencil presss from both sides 6 free state, diameter is as shown in 18.
Figure 3 shows that adjusting bolt head 19 is fixed on the schematic diagram in hand button.
Figure 4 shows that nut 10 is fixed on the schematic diagram in hand button.
For easy to adjust, adjusting bolt 9 bolt heads or nut 10 can be fixed in hand button, turn hand button, just can regulate the tightness of adjusting bolt 9 and nut 10 easily, thereby regulates the friction force of revolute pair, very convenient.
