Embodiment
With reference to accompanying drawing, the utility model tension tester embodiment is described further.
A kind of tension tester, comprise body 1, body 1 is provided with upper support seat 2 and lower support seat 3, upper support seat 2 and lower support seat 3 are provided with the fixture 4 for Gripping material, body 1 is connected with scale 5, described scale 5 is positioned at the side of fixture 4, scale 5 is provided with pointer 6, pointer 6 one end is connected with scale about 5 slippage, the other end abuts with fixture 4, during distance between measured material 4, upper and lower slippage pointer 6, conflicted with the fixture 4 of upper and lower both sides respectively in pointer 6 one end, then the distance between fixture 4 is read by the other end of pointer 6, when slippage, pointer 6 entirety is relatively-stationary, on the upside of conflicting respectively, when fixture 4 and downside fixture 4, the difference of scale is the distance at that time between fixture 4, scale can be indicated accurately by pointer 6, avoid the error because distance problem brings, simultaneously so simply easy to operate.When measuring the elongation at break of material, first measure the distance between two fixtures 4 before not stretching, distance after measuring Materials Fracture again between upper and lower two fixtures 4, namely the difference of two distances obtains the elongation at break of material, elongation at break is divided by the distance before stretching, can obtain the breaking elongation of material, it is more accurate to be measured by such mode.
In order to more accurately facilitate when reading, be provided with the locking piece for locking both between scale 5 and pointer 6, first both being locked when reading, avoid needing to fix with hand always, thus avoid pointer 6 to shake, ensure the stability of pointer 6, thus make reading comparatively accurate.
Embodiment one, scale 5 is fabricated from iron, locking piece is magnet 9, magnet 9 is fixed on pointer 6, by the suction of magnet and 5, scale, make scale 5 relative with pointer 6 fixing, as long as need to apply certain power up or down when sliding, pointer 6 just can be driven easily to slide, what this wanted be set using comparatively convenient and swift.
Embodiment two, locking piece can be lock(ing) bolt 7, pointer 6 is provided with the threaded hole be threaded with lock(ing) bolt 7, abut with scale 5 after the end thread connection of lock(ing) bolt 7, when both need fixing, twist-lock bolt 7, make scale 5 relative with pointer 6 fixing by abutting power, such lock mode makes right comparatively firm of both locking phases, and the situation that can not occur to continue to slide produces, and ensures the accuracy of reading.
Certainly, pointer 6 can arrange magnet 9 and lock(ing) bolt 7 simultaneously, if magnet 9 lost efficacy or was difficult to just use lock(ing) bolt 7 when stable carrying out locks, if also can make pointer 6 fixing-stable when magnet 9 locks, then only can use magnet 9, so comparatively convenient and swift.As preferably, the material of pointer 6 can use plastic material, such pointer 6 lighter weight, and pointer 6 is not easy to glide, and ensures that locking is stable.
Scale 5 is provided with chute 51, pointer 6 is connected with the slide block 611 that chute 51 coordinates, comparatively stable when pointer 6 slides like this, be not easy during slip to block, pointer 6 is also not easy to drop from scale 5, ensure that the convenient and swift of measurement.
In order to pick and place material convenience more on fixture 4, pointer 6 can be divided into two-part, and pointer 6 comprises linkage section 61 and probe 62, and described linkage section 61 one end is connected with scale 5 slippage, the other end and probe 62 hinged.When needs needs are measured, probe 62 is in normal operation position, and upper and lower slippage pointer 6 can make probe 62 and fixture 4 conflict, can measurement being completed, when without the need to measuring, probe 62 can be turned down around hinged place, probe 62 is packed up, makes probe 62 can not hamper other operation.
Linkage section 61 can be hinged by rotating shaft 63 with probe 62, rotating shaft 63 is arranged in miter angle, can vertically place like this after probe 62 turns down, so just also can not so rotate without the need to unnecessary stationary installation probe 62, be fixed without the need to unnecessary operation, operate more convenient.As preferably, on chained segment, slippage is connected with the keeper 8 for stoping probe 62 to rotate, when probe 62 is in normal operation position, keeper 8 is positioned at hinged place, stop probe 62 arbitrarily to rotate, the stability of pointer 6 when ensureing to measure, thus ensure measuring accuracy.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
