Description

A kind of pocket penetration test instrument

Technical field

The utility model belongs to the pen. technical field of performance test of material, specifically relates to a kind of pocket penetration test instrument.

Background technology

Pen. can be used to the soft or hard degree characterizing the materials such as pitch, ointment, rubber.The measurement of pen. is the degree of depth vertically being penetrated sample by the needle point measured under certain loading.The instrument measuring at present pen. on the market also exists the shortcomings such as complex structure, manufacturing cost are high, not portable.Therefore, be necessary that design one is rational in infrastructure, manufacture simple, portable penetrometer.To measure the analyzer of the pen. of sample, there is not been reported to measure the upper and lower displacement of shank to utilize clock gauge.Clock gauge commercially available a kind ofly converts general straight-line displacement the rotary motion of pointer to by gear or lever, on index dial, then carry out the displacement measuring instrument of reading.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of pocket penetration test instrument is provided, its structure is simple, reasonable in design and manufacture simple, low cost of manufacture, be easy to carry, and can effectively measure the pen. of the materials such as pitch, ointment, rubber.

For achieving the above object, the technical solution adopted in the utility model is: a kind of pocket penetration test instrument, it is characterized in that: comprise the clock gauge be arranged on bracing frame, counterweight, shank and pipe, described shank is through pipe, described pipe is fixed on bracing frame, pipe play the guiding role to moving up and down of shank, the bottom of described counterweight has a diameter to be greater than the blind hole of shank diameter, the top of described shank is inserted in the blind hole bottom counterweight, counterweight can be stablized to be placed on shank, the bottom needle point of described shank can insert in sample, the pen. of sample is measured by the upper and lower displacement of shank, the globular model measuring head of described clock gauge bottom withstands on counterweight top to measure the upper and lower displacement of counterweight and shank, described clock gauge is fixed on bracing frame.

Above-mentioned a kind of pocket penetration test instrument, is characterized in that: described counterweight, shank and pipe are stainless steel.

Above-mentioned a kind of pocket penetration test instrument, is characterized in that: the xsect of described shank is cylindrical, and one end of shank is needlepoint form, the other end is tack shape.

The utility model compared with prior art has the following advantages:

1, the utility model adopts clock gauge to measure the upper and lower displacement of shank, the pen. of energy Measurement accuracy sample.

2, shank of the present utility model can take out from pipe, counterweight can take off from shank, reinstall in packing box after the parts of this penetration test instrument can be taken apart, and compact structure of the present utility model, light, this penetration test instrument is easy to carry.

3, the utility model structure is simple, reasonable in design and manufacture simple, is conducive to promoting the use of.

Below by drawings and Examples, the utility model is described in further detail.

1-bracing frame; 2-clock gauge; 3-counterweight; 4-shank; 5-pipe; 6-sample.

Embodiment

As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model comprises the clock gauge 2 be arranged on bracing frame 1, counterweight 3, shank 4 and pipe 5, described shank 4 is through pipe 5, described pipe 5 is fixed on bracing frame 1, moving up and down of pipe 5 pairs of shanks 4 play the guiding role, the bottom of described counterweight 3 has a diameter to be greater than the blind hole of shank 4 diameter, the top of described shank 4 is inserted in the blind hole bottom counterweight 3, counterweight 3 can be stablized to be placed on shank 4, the bottom needle point of described shank 4 can insert in sample 6, the pen. of sample is measured by the upper and lower displacement of shank 4, the globular model measuring head of described clock gauge 2 bottom withstands on counterweight 3 top to measure the upper and lower displacement of counterweight 3 and shank 4, described clock gauge 2 is fixed on bracing frame 1.

In the present embodiment, described counterweight 3, shank 4 and pipe 5 is stainless steel.

In the present embodiment, the xsect of described shank 4 is cylindrical, and one end of shank 4 is needlepoint form, the other end is tack shape.

Principle of work of the present utility model is: during use, first pinch shank 4 with hand and upwards lift needle point, then sample 6 is placed in the bottom platform of bracing frame 1, then pinch shank 4 with hand and move down the upper surface making needle point just contact sample 6, write down the reading of clock gauge 2, then loose one's grip, make shank 4 under the Action of Gravity Field of counterweight 3 by the needle point pressing in sample 6 of shank 4, moving up and down of pipe 5 pairs of shanks 4 play the guiding role, after a period of time, when shank 4 no longer moves down, write down the reading of clock gauge 2, when no longer moving down according to the reading of clock gauge 2 during shank 4 initial position and shank 4, the reading of clock gauge 2 can obtain the pen. of sample 6.Sample 6 can be the materials such as pitch, ointment, rubber.

The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
