Description

Verticality gauge

The utility model relates to the instrument of measuring the stay degree of tilt, particularly a kind of Verticality gauge.

Stay in the various building structure, Ru Qiang, plate, post, stake etc., the every profession and trade standard all has clearly regulation to its degree of tilt permissible variation, as the standard of inspection of construction, operation examination, grade estimation.The general employing of conventional detection hung normal line method, measures with a yardstick and surveys horizontal sides and vertical edge, calculates degree of tilt (or claiming verticality) again.In many cases,, generally need two people to operate simultaneously because of vertical line can't be adjacent to tested surface, time-consuming, very inconvenient.

The purpose of this utility model be to provide a kind of simple in structure, measure convenient, fast, Verticality gauge intuitively.

The utility model is achieved in that a kind of Verticality gauge, comprise panel, bonnet, index dial, panel is provided with the indication view window, in the middle of the inner chamber that panel, bonnet constituted, be fixed with central layer, pointer is contained in the central layer front by bolster, plummet hangs osmanthus in the central layer back by support, and the end pin that is packed in the pointer bottom penetrates the microscler through hole of plummet afterbody by the through hole of central layer bottom.

Described support is made up of two bearings and a joint spider.In support one side the zero adjusting device is housed.Its structure is: at joint spider one end external thread is arranged, make threaded engagement with the screw of zeroing wheel central authorities, the zeroing wheel is by being bearing in the retainer spring location in the bearing hole, and joint spider is then by zeroing wheel location.Being provided with in the bonnet lower inside can be with the snap of plummet locking, this snap by reed, dial key and on tooth engaged, two stop tooths that are located on the bonnet form.Collapsible or the telescopic scale of at least one joint is housed in the bonnet outside.

Plummet keeps the vertical state under action of gravity, when the instrument outside is adjacent to tested surface (or by survey line), plummet drives pointer and does relative deflection, utilize the ratio amplification of pointer, the angle α (being degree of tilt) of tested surface (or by survey line) and pedal line is enlarged into angle β, directly read degree of tilt by index dial again, referring to shown in Figure 10.

Plummet and pointer are done non-isocentric circular arc swing, and for guaranteeing both coordinated movements of various economic factors, the pointer end pin is driven by the microscler through hole of plummet afterbody, moves up and down.For this reason, the display disc scale should be non-equidistant delineation, and scale planning can be tried to achieve by following formula:

By shown in Figure 10, l ₁And l ₂Be constant, can get the relational expression of β and α by sine:

β＝Sin ^-1(l ₁/l ₂?Sinα)。

Pointer should be zero together with end pin for the gravitational torque of its center of rotation, to eliminate the influence of pointer deadweight to measuring accuracy.

The effect of scale is lengthening measurement gauge length, improves measuring accuracy.

Advantage of the present utility model be simple and reasonable, small and exquisite portable, easy and simple to handle, measure quick, visual result.The stay and the verticality that are widely used in various construction and installation and fitting-out work detect.The utility model is used in combination with angle square, can do simple and easy horizontal survey.

By following embodiment the utility model is further elaborated.

With reference to Fig. 1-shown in Figure 9, it is such that the structure of a most preferred embodiment of the utility model is formed: be connected by screw between panel 9 and the bonnet 10 and be fixed with a central layer 4, central layer 4 front upper are carved with non-equi-distance scale, and the verticality meter full scale chooses ± and 5%.Pointer 5 is contained in central layer 4 fronts by bolster 18, and pointer 5 bottoms are fixed with end pin 6, and corresponding central layer 4 has a square through hole.Top, central layer 4 back is provided with a support, and this support is made up of two bearings 13 and supporting joint spider 2 thereon, and plummet 1 is hung on joint spider 2.Joint spider 2 one ends have external thread, make threaded engagement with the screw of zeroing wheel 3 central authorities, return to zero and take turns 3 by being bearing in retainer spring 12 location in bearing 14 holes, and 2 of joint spiders are taken turns 3 by zeroing and located.The above-mentioned balancing controls that are this instrument.Plummet 1 afterbody is provided with a microscler through hole, and pointer 5 end pins 6 pass this microscler through hole by the square hole of central layer 4, and during measurement, when plummet 1 drove pointer 5 swings, end pin 6 can move up and down in plummet 1 microscler through hole.

Under transportation or non-measurement state, lock plummet, prevent that instrument from damaging is very necessary, for this reason, be provided with snap in bonnet 10 lower inside, this spring is by reed 15, dial key 8 and on tooth engaged 16, two stop tooth A, B that are located on the bonnet 10 form.By pressing group key 8 that plummet 1 is in the lock state or duty.Snap has two effects: 1. when group key 8 was allocated to position A, the swing that reed 15 restriction plummets 1 work exceeds effective range prevented pointer 5 collision deformations; When 2. not using this instrument, push position B, plummet 1 is blocked, avoid rocking by reed 15 dialling key 8.Needing to dial key 8 earlier when stirring key 8 compresses into.Discharging reed 15 positions, group key 8 back is fixed by stop tooth.

Scale 7 is equipped with in bonnet 10 outsides, scale 7 can be a joint or a more piece, pattern can adopt collapsible (external), also can adopt telescopic (external or built-in), present embodiment is selected collapsible more piece scale for use, each the joint link with hinge, scale 7 by screw attachment on bonnet 10, all establish the biting point on scale 7 ends and the bonnet 10, keep a straight line with the instrument side so that scale 7 is opened its outside, back.According to specific service condition, scale can be installed on instrument top or bottom.

The using method of this instrument is as follows: instrument is answered periodic calibrating, and its method is: 1. make a vertical baseline on wall or any vertical plane; 2. open scale; 3. snap is allocated to position A; Scale outside straight line is overlapped with vertical baseline; 5. observe pointer and whether be offset,, then gently tune zero wheel it is made zero if circle reading is non-vanishing.

Instrument is in use dialled key should be adjacent to tested surface (or by survey line) with the instrument side at position A, treats that pointer stabilizes to get final product reading.Positive negative number representation vergence direction on the index dial.Finish using, scale is amounted to, dial key and be allocated to position B.

Figure 11-Figure 14 is the diagram of this instrument certain applications example.
