Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1,2 shows respectively solid, the decomposition texture schematic diagram of a specific embodiment of the utility model altitude location scale, for convenience of explanation, only shows the part relevant with the present embodiment.
This altitude location scale comprises a chassis 101, and 101 are provided with an outer sleeve 102 on the chassis, are appreciated that, chassis 101 is generally the object with certain thickness and weight, can be stable be seated on ground or certain table top, in drop test, chassis 101 places on certain surface level usually.In outer sleeve 102, be provided with a telescopic inner sleeve 103, (can near upper edge) be provided with an illuminator 104 on the top of inner sleeve 103, this illuminator 104 can send colorama to the direction perpendicular to the central shaft of inner sleeve 103, and its light beam is narrower, can ignore its diameter.Outer sleeve 102 and inner sleeve 103 common bottom surfaces perpendicular to chassis 101, and then perpendicular to surface level, therefore, the light that illuminator 104 sends can be parallel with surface level.In addition, outer wall at inner sleeve 103 is carved with the scale mark (not shown) that characterizes height, this scale mark is along the length direction delineation of inner sleeve 103, the scale value of the part of aliging with the top of outer sleeve 102 characterizes is that the horizon light that sends of illuminator 104 is apart from the height of the bottom on chassis 101, namely apart from the height of level ground or supporting bable tops.
When adopting this altitude location scale to carry out drop test, in advance inner sleeve 103 is stretched to corresponding height and fixing, the height of its stretching is determined by the scale mark on the inner sleeve 103, then open illuminator 104, object is upwards promoted, the horizontal light beam that its bottom is sent with illuminator 104 is in sustained height, then carries out drop test.Test after finishing is closed illuminator 104, in inner sleeve 103 retraction outer sleeves 102, to save the space.
Because adopting horizontal light beam illustrates highly, visual good, so that the operator all can hold height at an arbitrary position accurately, needn't as traditional approach, must keep the sight line horizontal alignment in object bottom and the groove that represents preset height, not only improved greatly the accuracy of altitude location, and convenient operation more.
In the present embodiment, the scale mark on the inner sleeve 103 can be delineated after assembling inner sleeve 103 and outer sleeve 102.Because the residing height in object bottom is by checking that the scale mark that aligns with the top of outer sleeve 102 determines, so after outer sleeve 102 installs, its length of exposing on the chassis 101 can directly affect scale reading corresponding to its top, therefore when having error between the assembling height of outer sleeve 102 and the height preset, just can bring measuring error.Therefore, the present embodiment carries out the accuracy that the scale delineation can guarantee altitude location again after assembling inner and outer sleeves.
Shown in Fig. 2,3,4, as a kind of improvement of the present embodiment, can offer chute 1031 with the central axes of inner sleeve 103 at the outer wall of inner sleeve 103, and the slide rail 1022 that cooperates with chute 1031 in the inwall setting of outer sleeve 102.Like this, can limit the active orientation of inner sleeve 103, prevent that inner sleeve 103 from rotating in flexible process, so that calibrate, and prevent the light direction randomly changing of illuminator 104 and be not easy to test.Certainly, illuminator 104 is set to 90 degrees with chute and slide rail, and the orientation of the light that it sends and chute and slide rail is perpendicular.
Preferably, the length of slide rail 1022 is much smaller than the length of chute 1031, and is positioned at the top of outer sleeve inwall, and simultaneously, the end that chute 1031 extends to the chassis direction can a distance, edge cut-off under the distance inner sleeve, its terminal stopper slot 1032 that forms.Like this, when inner sleeve 103 protruded upward, when being about to mark outer sleeve 102, an end of slide rail 1022 can be butted on the stopper slot 1032, and then stoped inner sleeve 103 to continue to mark.
Further with reference to figure 2, the present embodiment can be offered a hole 1023 at outer sleeve 102, gets a fixture 105 and penetrates this hole 1023, and its end is pressed on the inner sleeve 103, friction force between inner sleeve 103 and this fixture 105 and the outer sleeve 102 is increased, so inner sleeve 103 is fixing.This fixture 105 specifically can be a screw or other parts that can freely stretch into and unclamp.
With reference to figure 4, preferred, this hole 1023 can be positioned at slide rail 1022 places on the inwall of outer sleeve 102, and fixture 105 is penetrated from slide rail 1022 places, and its end is butted in the chute 1031 on the inner sleeve 103 just.Because the thickness of outer sleeve 102 is usually thinner, if in the place's perforate of non-slideway, the penetration depth of fixture 105 must be very limited, and when unscrewing fixture 105 with telescopic inner sleeve cylinder 103, fixture 105 is very easy to come off, for test job is made troubles.And the present embodiment is in the slide rail 1022 part perforates of outer sleeve 102, because slide rail 1022 has certain thickness, therefore to stretch into the length of outer sleeve 102 longer for fixture 105, just is not easy to come off when outwarding winding fixture 105, and then avoids fixture 105 to lose and convenient operation.
In the present embodiment, the illuminator 104 preferred laser pens that adopt, the collimation of its emergent light is better and light beam is narrower, can be approximately straight line.Can determine more accurately like this height, the height error of avoiding the diameter of light beam itself to bring.
Further with reference to figure 3, for the fixed laser pen, can offer in advance the through hole 1033 of two symmetries near the zone of coboundary on the top of inner sleeve 103, laser pen is passed these two through holes 1033 fix realizing.
Further, a locking member 106 can also be set at the top of inner sleeve 103, specifically can be a lock-screw, so that laser pen is further locked, prevents its slip.Such as Fig. 5, can also offer in the bottom of locking member 106 bar-shaped trough 1061 that is complementary with a figure shape of laser pen (as circular, square etc.).When laser pen was locked, a body of laser pen embedded in the bar-shaped trough 1061 just, made it up and down or to act on to slide, and had further strengthened the steadiness of laser pen, and then had increased the precision of altitude location.
The horizontal light that the altitude location scale that the utility model provides adopts illuminator to send is illustrated highly, visual good, and do not need to keep human eye and object bottom surface to be on the same level, and then the error of having avoided human eye observation to cause, so that test result is more accurate.And this scale is convenient operation and movement relatively, is applicable to various altitude location occasions.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
