Description
Technical field
The utility model belongs to technical field of measuring equipment, is particularly useful for the two-way extension type measuring staff of one that down-hole measures drift section size.
Background technology
Along with the development of science and technology, design and the production of mine also tend to standardization.For a long time, under measuring well, the length of drift section all adopts tape measure, steel tape or unidirectional scalable measuring staff, but often run into following problem in practical operation, when one end, surveyed tunnel because of equipment exist or highly too high and people cannot be reached time, tape measure cannot use because one end can not get fixing; When measuring large section roadway, steel tape can bend because pendulous tank is excessive; When the two ends in tunnel all cannot arrive, unidirectional scalability measuring staff just can not perfect measurement drift section size.When facing the problems referred to above, people also find a lot of solution, such as: steel tape and regular length batten with the use of, unidirectional scalability measuring staff and regular length batten with the use of.But exist need operating personnel many, carry inconvenience and the large shortcoming of error.Find a kind of energy equipment that is easy, that measure underworkings cross dimensions fast and accurately just to seem particularly important, this has very large meaning to join Wind Coverage Calculation, ventilation resistance calculating and the [underground of mine.
Utility model content
The purpose of this utility model is the deficiency overcoming the existence of existing measuring equipment, provides a kind of simple, quick, portable and accurate one two-way extension type measuring staff.
The utility model technical solution problem adopts following scheme:
A kind of two-way extension type measuring staff, comprise braces, intermediate bar, first sub bar, second sub bar, 3rd sub bar, 4th sub bar, sub bar hinge point, groove and termination, wherein sub bar hinge point is by bullet, spring and fixed leg composition, described first sub bar, second sub bar, 3rd sub bar, 4th sub bar and intermediate bar are by the seamless link of sub bar hinge point, described braces is installed on intermediate bar, the bullet of described sub bar hinge point utilizes the spring be enclosed within fixed leg to carry out work, described termination is installed in the 3rd sub bar, the end of the 4th sub bar, it is characterized in that: the two ends of described two-way extension type measuring staff can apply to measure, the side of described intermediate bar, the first sub bar, the second sub bar, the 3rd sub bar and the 4th sub bar is provided with groove and there is scale on surface.
Design feature of the present utility model is also:
The number of described sub bar and length change along with the range size of two-way extension type measuring staff.
The length of described intermediate bar is fixing visual.
Further, the scale on described sub bar is from the 3rd sub bar to the first sub bar, from the 4th sub bar to the second sub bar successively with evenly arrangement from small to large zero.
The beneficial effects of the utility model are: two ends of the present utility model all scalable thus for measure, sub bar side is provided with groove, avoiding sub bar to rotate makes hinge point come off, scale on sub bar is started from scratch successively from end to intermediate bar and is evenly arranged from small to large, make the staff's convenient reading holding intermediate bar, efficiently solve surveying instrument operation inconvenience and personnel cannot arrive brought problem.

The utility model is described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As Figure 1-Figure 4, a kind of two-way extension type measuring staff, comprises braces (1), intermediate bar (2), first sub bar (3), second sub bar (4), 3rd sub bar (5), 4th sub bar (6), sub bar hinge point (7), groove (8) and termination (9), wherein sub bar hinge point (7) is by bullet (10), spring (11) and fixed leg (12) composition, the first sub bar (3), second sub bar (4), 3rd sub bar (5), 4th sub bar (6) and intermediate bar (2) are by sub bar hinge point (7) seamless link, braces (1) is installed on intermediate bar (2), the bullet (10) of sub bar hinge point (7) utilizes the spring (11) be enclosed within fixed leg (12) to carry out work, and termination (9) are installed in the 3rd sub bar (5), the end of the 4th sub bar (6), the two ends of this two-way extension type measuring staff can apply to measure, and intermediate bar (2), first sub bar (3), second sub bar (4), the side of the 3rd sub bar (5) and the 4th sub bar (6) is provided with groove (8) and there is scale on surface.
As further improvement, the number of sub bar and length change along with the range size of two-way extension type measuring staff.
The length of intermediate bar (2) is fixing visual.
Scale on element is from the 3rd sub bar (5) to the first sub bar (3), from the 4th sub bar (6) to the second sub bar (4) successively with evenly arrangement from small to large zero.
The principle of work of the present embodiment and using method
Survey tunnel and have at least one end personnel to arrive
Now, termination (9) is pulled in the one end in tunnel, sub bar can be drawn out makes it be drawn out completely and be fixed up until bullet (10) ejects, if under the condition that two-way extension type measuring staff side sub bar range allows, until the 3rd sub bar (5) or the 4th sub bar (6) arrive the other end in tunnel, so the length and width in tunnel or height are that scale on the sub bar of side is long adds intermediate bar length (2); If two-way extension type measuring staff side sub bar range does not reach requirement, can measure with the use of opposite side sub bar, so the length and width in tunnel or height are the long summation with intermediate bar length (2) of both sides sub bar scale.
Survey two ends, tunnel personnel and all can not arrive
Now, staff stands in the centre position in tunnel, pull the sub bar at two ends respectively, two ends sub bar can be drawn out makes it be drawn out completely and be fixed up until bullet (10) ejects, when two ends (9) all arrives tunnel wall, start reading, so the length and width in tunnel or height are the long summation with intermediate bar (2) length of both sides sub bar scale.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
