Abstract
A kind of orientable tape measure, comprise tape measure body, compass and screw, the housing of described tape measure body has some screw holes, compass is welded with the iron plate with described screw hole respective numbers, iron plate is the iron plate of band screw hole, screw hole on described iron plate matches with the screw hole on the housing of tape measure body, makes tape measure body and compass be that screw is connected; Described compass is the compass with index plate, and the scale division value of compass is 1 degree.The utility model can measure the width of the cross wall under the angle and this deviation angle that cross wall departs from, this deviation angle is comparatively accurate, namely the utility model is on the basis measuring cross wall length, obtains the deviation angle of cross wall accurately, the work of very big mapping worker easily on engineer applied.
Description
Technical field
The utility model relates to a kind of tape measure, particularly relates to a kind of tape measure carrying out accurate location survey.
Background technology
In building field, use the length of tape measure buildings comparatively conventional, if application number is the Chinese utility model patent of 201120391671.7, disclose a kind of building tape measure with compass, it inlays a compass on the front of tape measure, make tape measure have the effect of direction indication, but this tape measure does not have the function of accurate location survey.
When construction area building, when known two fixed points (pillar), distance between two fixed points is the vertical wall length of buildings, if cross wall width is set-point, when construction, be parallel to each other to make two cross walls of fixing a point to draw, then need to measure and obtain the length of cross wall and the cross wall deviation angle relative to fixed point, and in prior art, there is no the device of disposable direct measurement two parameters, thus need in measuring process repeatedly to determine reference point, measuring process is comparatively numerous and diverse.
Utility model content
In order to solve the problem, the utility model provides a kind of orientable tape measure, and it uses the compass with accurate calibration as locating device, and one-shot measurement can obtain the length of cross wall and the cross wall deviation angle relative to fixed point.Meanwhile, the utility model makes compass and tape measure body adopt screw to be connected, and a compass can coordinate with multiple tape measure, optimizes resource distribution.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of orientable tape measure, comprise tape measure body, compass and screw, the housing of described tape measure body has some screw holes, the excircle of compass is welded with the iron plate with described screw hole respective numbers, iron plate is provided with screw hole,, the screw hole on described iron plate matches with the screw hole on the housing of tape measure body, makes tape measure body and compass be that screw is connected; Described compass is the compass with index plate, and the scale division value of compass is 1 degree.
Further, in the centre position of compass, laser lamp is installed, described laser lamp is the laser lamp of adjustable angle, the adjustment radiative direct projection direction of laser lamp, direction is stretched out according to oriented tape measure, the deviation taken measurement of an angle caused by human factor during cancel job, ensure tape measure in use actual take measurement of an angle consistent with first retainer.
Beneficial effect: the scale division value of compass of the present utility model is 1 degree, the minimum position angle that namely tape measure can be measured is 1 degree.The utility model can realize the exact position according to a known vertical wall arbitrarily, the strict width of cross wall and roughly direction, determine the precision offset angle of cross wall, and then make two cross walls realize parallel construction, engineer applied brings great convenience to mapping worker.In addition, the utility model provides the movable connection method of a kind of compass and tape measure body, and a compass can repeatedly be utilized, and install and take conveniently, transplantability is good.Because the utility model has installed laser lamp, measurement can not only be carried out by day, also can realize night work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that tape measure body is connected with compass;
Fig. 3 is the schematic diagram of the principle that the cross wall using the utility model to solve two fixed point extractions is parallel to each other.
Wherein: 1. screw, 2. iron plate, 3. tape measure body, 4. compass.
Embodiment
In order to the technical scheme of utility model is more clearly described, below in conjunction with drawings and the specific embodiments, the utility model is further illustrated.
Embodiment: as shown in Fig. 1-2, a kind of orientable tape measure, comprise tape measure body 3, compass 4 and screw 1, the housing of described tape measure body 3 has some screw holes, compass 4 is welded with the iron plate 2 with described screw hole respective numbers, specifically, the housing of tape measure body 3 has 3 screw holes, the excircle of compass 4 is welded with 3 iron plates 2.Iron plate 2 is provided with screw hole, and the screw hole on described iron plate 2 matches with the screw hole on the housing of tape measure body 3, and tape measure body 3 is connected for screw 1 with compass 4; Described compass 4 is the compass with index plate, and the scale division value of compass 4 is 1 degree.In the present embodiment, described orientable tape measure, in the centre position of compass, laser lamp is installed, described laser lamp is the laser lamp of adjustable angle, utilize the direct projection function of laser lamp, ensure that tape measure can carry out along set direction when in use, the deviation taken measurement of an angle caused by human factor when eliminating operation, ensure tape measure in use actual take measurement of an angle consistent with the orientation angle of pointer.
As shown in Figure 3, in known two fixed points, i.e. A point and B point in figure, these 2 positions of installing for pillar, distance between two fixed point A and B is the vertical wall length of buildings, cross wall width is the distance of fixed point to dynamic point, dynamic point is the C point in figure and D point, if the width of cross wall and cross wall are set-point relative to the deviation angle of set point, when construction, in order to the cross wall making two A and B that fix a point draw is parallel to each other, first with A point for reference point, measure given deviation angle, under this deviation angle, measure the length of given cross wall, again with B point for reference point, measure given deviation angle, under this deviation angle, measure the length of given cross wall, because two cross walls are equal with cross wall length with the deviation angle of reference point, must be two parallel cross walls, use the tape measure in the present embodiment, solve in prior art the device not having disposable direct measurement two parameters, the problem repeatedly determining reference point is needed in measuring process, be beneficial to survey crew convenient, judge the parallel degree of two cross walls fast, in building course, construction personnel are facilitated to determine the construction position of two parallel cross walls accurately.
