Abstract
The utility model relates to a level meter with vernier used for measuring inclination, composed of a casing, a circumference dial, a vernier shaft, a turning gear, a vernier rack, a vernier plate, a transversal pointer, a transversal scale, a standard scale connected with the casing, etc. The level meter with vernier is not easily affected by environmental condition, can improve measuring accuracy, can read out scales visually and accurately, learns the inclination of measured objects, and provides scientific data for operation. The accuracy of the level meter with vernier can reach (+/-) 20 seconds, and the vernier plate is positioned after a brake mechanism is installed so as to identify readings accurately. The level meter with vernier can measure any angle of the objects based within the 360 DEG of a horizontal plane.
Description
The utility model relates to the device of measuring degree of tilt.
Widespread usage frame level in operations such as equipment installation, construction work at present, level formula instruments such as surveyor's staff, or with plumb bob with inspection side levelness or verticality.There are the following problems for above-mentioned apparatus: 1, be subject to environmental influence, be acted upon by temperature changes as level formula instrument, plumb bob is subjected to the influence of wind-force in the open air, measures not accurate enough; 2, do not have reading, judge whether to be up to the standard or vertically with naked eyes entirely, can not be directly perceived, learn its degree of tilt exactly, the data of science are provided for operation.In addition, present inclinometer can only be measured the angle that can only detect between object plane, and not energy measurement based on the various angles in 360 ° of surface level.
The purpose of this utility model is to provide a kind of vernier horizontal detection instrument, and this instrument is not subject to the influence of environmental baseline when detecting, can improve accuracy, can intuitively and exactly read its scale, learns the degree of tilt of measured object, for operation provides science data.This instrument can be measured the angle of each object plane based on surface level in 360 ° of scopes simultaneously.
The utility model vernier horizontal detection instrument is achieved in that the housing that an one side has the circumference index dial is set, the vernier shaft and the housing bearing of vernier frame are housed, slew gears such as thimble connect, this vernier shaft should be vertical with the circumference index dial and concentric, entad arc alidade is equipped with in vernier frame lower end, vernier dial should with the scale of circumference index dial part near or have local overlapping, housing is equipped with transparent bonnet, connecting horizontal pointer near on the vernier shaft at bonnet place with thimble, thimble axially vertical with vernier shaft, the horizontal directive tendency chi is fixed in the vernier frame, or be fixed on the vernier shaft with support, the outside of housing is provided with station meter, and the detection reference face of this chi should be vertical with the diameter line of circumference index dial.
The utility model vernier horizontal detection instrument in use, its detection reference face and detected (or line) are drawn close, adjust vernier shaft to horizontality (" 0 " of pointed horizontal directive tendency chi) by the observation horizontal pointer, alidade is not because action of gravity is remained vertically downward by the influence of circumference index dial rotation direction, watch the scale reading of the circumference scale of vernier dial center scale sensing, can learn by the degree of tilt of side object plane.As wish to get and know the more accurate number of degrees, can find out two dial scales and overlap part as using other vernier measuring tool, read " degree " following unit.The precision of this detector generally can reach ± and 20 seconds, can provide directly perceived and science data accurately for detection.After learning the degree of tilt value as desire to ask and be up to the standard or vertically, can carry out adjustment work in the operation by these data, bring convenience to the constructor, accomplish to know what's what.Simultaneously, the alidade and the pointer of this detector are loaded in the housing, and adopt the accurate machine construction mode, are not subject to the influence of environmental baseline during detection, can guarantee the accuracy of measuring.The measurement of this instrument is that the pedal line that forms with vernier frame (dish) and horizontal pointer is a benchmark, the corresponding angle that predicts tested object plane and surface level, and be arbitrarily angled in 360 ° of scopes.
Be described further below in conjunction with accompanying drawing
Fig. 1 is the structural representation of the utility model vernier horizontal detection instrument embodiment one
Fig. 2 is Figure 1A-A direction cut-away view
Fig. 3 is two the structural representation of the utility model embodiment
Fig. 4 is the front appearance figure of above-mentioned two embodiment
Side cut-away view by Fig. 1 can be seen essential structure of the present utility model, and this figure also is one of embodiment of the present utility model simultaneously.At the left side of housing 1 fixed installation circumference index dial 2, this dish is hollow shape.On the housing outside the circumference index dial translucent cover 3 is housed, the housing rear portion is provided with transparent bonnet 4; At circumference index dial circle centre position vernier shaft 5 is set, its front end is loaded on the translucent cover 3 with thimble 13, and the rear end is loaded on the support 14 with thimble 6, and support 14 is become one with housing.The vernier shaft front end is equipped with vernier frame 8, and this is affixed with screw with vernier shaft.Alidade 10 is equipped with in vernier frame lower end, and this dish can be overlapped with the circumference index dial; The vernier shaft rear portion connects horizontal pointer 7 with thimble, and horizontal directive tendency chi 9 is loaded on the rear portion of vernier frame near the most advanced and sophisticated place of pointer.Housing is provided with station meter 11 outward, and its reference field 12 should be vertical with the circumference dial diameters.Fig. 2 has shown the connecting mode of horizontal pointer 7 and vernier shaft 5, and there is a groove at axle 5 rear portions, this groove and vernier frame in the same way, pointer 7 is packed in it and to be connected with spools 5 with thimble 15.Fig. 3 is two of embodiment of the present utility model.In testing process, can not watch the scale of detector sometimes easily because of user's angle of living in, need alidade is temporarily located, read numerical value in face of again detector being moved to.Can adopt following structure: 2 self-aligning bearings 18,19 are housed at the middle part of vernier shaft 5, and make the two at regular intervals for this reason.Bearing 18,19 is loaded in the bearing holder (housing, cover) 23, and bearing holder (housing, cover) links to each other with housing with bearing bracket stand 24.The brake rod 20 that a bottom is set is off-centre or flat, this brake rod passes housing and bearing holder (housing, cover), and the lower end places 2 vernier shafts 5 between bearing other, and connects brake handles 22 in the upper end of this bar by pin 21.Pulling handle 22 can be fixing with axle 5, and corresponding alidade 10 also can be positioned.Horizontal directive tendency chi 9 is fixed on the vernier shaft by support 17.In order accurately to discern reading, can magnifier 25 be set in alidade 10 fronts, the hand tenon of this magnifier is loaded on the vernier shaft, so that magnifier can move with alidade.This device can make the gauger be in distance, angle, light condition when not good, this instrument can be moved to the position of being convenient to observe and watch.Fig. 4 is front appearance figure of the present utility model.
