Technical field
The utility model relates to laser range finder technical fields, and in particular to a kind of portable laser rangefinder.
Background technique
Portable laser rangefinder is the instrument for carrying out Accurate Determining to the distance of target using laser.Laser range finder
A branch of very thin laser is projected to target at work, the laser beam of target reflection is received by photoelectric cell, timer measurement swashs
Light beam is calculated from the received time is emitted to from observer's range-to-go.Hand-held portable laser range finder is extensive
For short-range measurement, as the length and width in house, layer are high.
But existing portable laser rangefinder is during use, however it remains a biggish defect, in high-altitude
During outdoor measurement, especially during the exterior wall structures to skyscraper measure, staff is often
It needs to lean out outside window, partly poises body and measure, this undoubtedly has great risk, and slightly not very will lead to can not retrieve
Consequence.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to use, versatile portable laser rangefinders.
For achieving the above object, the technical scheme adopted by the utility model is a kind of portable laser rangefinder,
Including handle, probe is arranged in the left end of the handle, and handle inner is provided with extension bar containing cavities, the extension bar containing cavities
Opening is located at the right end of handle, is provided with extension bar in extension bar containing cavities；The extension bar includes outer tube and is arranged in inner tube
In interior bar, the outer tube matches with extension bar containing cavities, and the top and bottom of outer tube are provided with guiding along its length
Slot；The upper and lower part of the handle right side is respectively arranged with a connecting plate, solid on the opposite surface of the connecting plate
Surely it is provided with a vertical pin shaft, the pin shaft is matched with guide groove and is inserted into guide groove；In the outer tube right end
The heart is provided with the through-hole matched with interior bar, and the right end of the interior bar is threaded through in through-hole, and the left end setting of interior bar is limited
Bit slice.
Preferably, the leading flank of the handle and trailing flank are provided with measurement numerical value display screen.
Preferably, the inner surface of the outer tube right end and limit film has surface to be provided with magnetic piece.
The beneficial effects of the utility model embody a concentrated reflection of, and can lengthen the decreased food of laser range finder, and structure letter
It is single, easy to use.Specifically, the utility model in use, can be used as common laser range finder under normal circumstances
It carries out using being highly convenient for carrying.When encountering the special circumstances such as exterior wall structures measurement, interior bar and outer tube are extracted out simultaneously,
Longest can be by lengthening of handle to close to three times, and the hand-holdable interior bar of staff operates the utility model expenditure outside window, mentions
High safety.And after the outer tube of the utility model is fully drawn out, outer tube can be rotated around pin shaft, so as to adjust
The direction of laser range finder probe, so that the various use environments for adapting to turning measurement, having barrier obstruction, versatility are extremely strong.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is a kind of use state diagram of structure shown in Fig. 1.
Specific embodiment
A kind of portable laser rangefinder in conjunction with shown in Fig. 1 and 2, including handle 1, the left end of the handle 1, which is arranged, to be visited
First 2, the probe 2 includes laser emitter, laser pickoff, timer etc., this is the prior art, and details are not described herein again.
The utility model the difference is that, the handle 1 is internally provided with extension bar containing cavities 3, the extension bar
The opening of containing cavities 3 is located at the right end of handle 1, is provided with extension bar in extension bar containing cavities 3.The general handle 1 is in rectangular
Body shape, extension bar containing cavities 3 are also rectangle, corresponding 1 upper opening of handle of right end.
The extension bar includes outer tube 4 and the interior bar 5 that is arranged in inner tube, and the outer tube 4 matches with extension bar containing cavities 3
Close, that is to say, that when extension bar containing cavities 3 in a rectangular parallelepiped shape when, the general shape of outer tube 4 also in a rectangular parallelepiped shape, and size with
Extension bar containing cavities 3 match.The top and bottom of outer tube 4 are provided with guide groove 6 along its length, as shown in figs. 1 and 2,
Guide groove 6 extends in left-right direction, and left and right directions is the length direction of outer tube 4 in figure.The top of 1 right side of handle
It is respectively arranged with a connecting plate 7 with lower part, the connecting plate 7 is fixedly installed a vertical pin shaft on opposite surface
8, the pin shaft 8 is matched with guide groove 6 and is inserted into guide groove 6.In the case that the pin shaft 8 and guide groove 6 match, both
It can use the two to be oriented to the flexible of outer tube 4, while pin shaft 8 can play the role of articulated shaft again, realize outer tube 4
Rotation.About orientation problem of the outer tube 4 after rotation, specific structure is more, such as: it is covered outside the pin shaft 8 and sets one layer of rubber
Layer is only slightly firmly just able to achieve the rotation of outer tube 4 and stretches using rubber layer increasing friction force.It is also possible to pin shaft 8 to adopt
With ferrous material, one layer of magnet is arranged in 6 slot bottom of guide groove, also needs slightly firmly just to be able to achieve rotation and stretch.
4 right end of outer tube is provided centrally with the through-hole matched with interior bar 5, and the right end of the interior bar 5 is worn
In through-hole, when use, is oriented to interior bar 5 using through-hole, realizes the flexible of interior bar 5, the left end of interior bar 5 is provided with limit
Piece 9, for preventing interior bar 5 from deviating from from outer tube 4.In order to realize the positioning after the stretching of interior bar 5, the interior table of 4 right end of outer tube
Face and limit film 9 have surface to be provided with magnetic piece 10.
The measurement numerical value display screen of the utility model is general to be arranged on handle 1 as conventional laser range finder, but
Since the utility model needs to adjust the angle, for the ease of observation, better way is the leading flank and rear side of the handle 1
Face is provided with measurement numerical value display screen.
The utility model in use, can be used as common laser range finder under normal circumstances and carry out using very
It is easy to carry.When encountering the special circumstances such as exterior wall structures measurement, interior bar 5 and outer tube 4 are extracted out simultaneously, longest can be by hand
Handle is lengthened to close to three times, and the hand-holdable interior bar 5 of staff operates the utility model expenditure outside window, improves safety
Property.And after the outer tube 4 of the utility model is fully drawn out, outer tube 4 can be rotated around pin shaft 8, so as to adjust laser
The direction of rangefinder probe 2, so that the various use environments for adapting to turning measurement, having barrier obstruction, versatility are extremely strong.
