Technical field

The utility model relates to a kind of construction work checkout equipment, is specifically related to a kind of direct-reading measurement of plate thickness instrument.

Background technology

Slab thickness is an important indicator of building size, usually the conventional method that detects slab thickness is directly to measure with survey instrument, in order to make measurement result accurate, below floor, need survey instrument be propped up by instrument, make it and the underfloor flush, need two to three people during the general measure floor, and will could realize by devices such as framing scaffolds.Existing non-destructive detecting device such as ultrasonic measuring instrument, though to the floor not damaged, use inconvenience, cost an arm and a leg, the maintenance cost height, and when the thickness critical point, can produce dispute.Therefore need a kind of with low cost, accurate and visual, easy to operate slab thickness checkout equipment.

Summary of the invention

In order to realize above-mentioned technical purpose, the utility model discloses a kind of direct-reading measurement of plate thickness instrument, comprise sleeve, pull bar, on measure piece, measure piece down, it is characterized in that: described sleeve both sides are provided with open slot, described measurement piece two arms of going up stretch out from opening, can slide up and down along open slot during measurement, on measure the piece side and be provided with pointer.

Further technical scheme also comprises:

Described sleeve arranged outside has scale, and the bottom is provided with a set collar;

The described piece of measuring down is made of tetragonal flexible cranking arm, and the one summit is connected with set collar by bolt;

Described pull bar passes sleeve, and the bottom links to each other to angle point with above-mentioned summit.

Be provided with the spring hold-down devices in the described sleeve, the spring lower end is against to be measured on the piece, and last measurement piece is imposed downward pressure.

Raise the pointer height, the translation scale, pointer equals the distance of 0 scale to the sleeve bottom surface to the height of last measurement piece bottom.

The upper end of flexible two arms that link to each other with sleeve of cranking arm is provided with flanging, flexiblely cranks arm that described flanging is perpendicular to the sleeve bottom when launching, and two flangings are against on the bottom surface of plate during the measurement thickness of slab.

Described pull bar is provided with the register pin that is used to limit amplitude of oscillation degree on the described flexible upper arm of cranking arm, and its set positions is when the pulling pull bar is vertical with sleeve to the flexible upper arm of cranking arm, and described register pin just is against the position of sleeve tube cap bottom.Avoided pull bar with respect to the sleeve amount of being pulled through like this, having made on flexible two upper arm of cranking arm pendulum excessively, with the sleeve bottom not on a surface level, produce measuring error.

The beneficial effects of the utility model are:

The effect of the flexible and location that the utilization of this device is cranked arm need not extra manpower and materials at soffit fixation measuring equipment, and can guarantee its levelness and verticality.Utilize the spring hold-down devices, fix measuring equipment automatically.And adopt the design of raising pointer and translation scale, make when being equipped in reading numerical values more convenient.The utlity model has accurate and visual, conveniently read, advantage easy and simple to handle, cheap for manufacturing cost.

Embodiment

In order to make the technical solution of the utility model and technical purpose be easier to understand, the utility model is further introduced below in conjunction with drawings and the specific embodiments.

As shown in the figure, the utility model discloses a kind of direct-reading measurement of plate thickness instrument, by sleeve 1, pull bar 2, spring hold-down devices 3, on measure piece 5, measure piece 6 down and constitute, described sleeve 1 both sides are provided with

open slot

8,5 liang of arms of last measurement piece stretch out from opening, during measurement, slide up and down along open slot, on measure piece 4 sides and be provided with pointer 4.Sleeve 1 outside is correspondingly provided with scale, and the bottom is provided with a set collar 7; The described piece 6 of measuring down is made of tetragonal flexible cranking arm, and the one summit is connected with set collar 7 by bolt, is fixed on the sleeve; Pull bar 2 passes sleeve 1, and the bottom links to each other to angle point with the summit.Spring hold-down devices 3 is arranged in the sleeve 1, and the bottom is pressed in to be measured on the piece 5.The upper end of flexible two upper arm linking to each other with sleeve 1 of cranking arm is provided with flanging, and the flexible described flanging of cranking arm during expansion is perpendicular to sleeve 1 bottom.

As Fig. 4 and shown in Figure 6, pull bar 2 is provided with register pin 10, perpendicular to pull bar 2, when flexible crank arm upper arm and sleeve 1 were vertical, register pin 10 just was against sleeve tube cap bottom position to its set positions, with respect to sleeve 1 at pulling pull bar 2, pull bar 2 just can not continue upwards pulling again, avoided the upwards amount of being pulled through of pull bar 2, and made the flexible upper arm distortion of cranking arm, with the sleeve bottom situation on a surface level not.Register pin 10 length are made as with the overall diameter of sleeve 1 and equate, move and move up and down along with pull bar 2 along open slot, and in operating process, when upwards spurring analyzer, utilize the positioning action of register pin 10, pulling pull bar 2 can drive sleeve 1 and move upward, and need not operating personnel and spurs pull bar 2 and sleeve 1 more respectively, and is easy to operate.

Above-mentioned sleeve 1 external diameter is made as 1cm, and the little diameter of trying one's best can make when needs burrow to floor, reduces the destruction to building, can restore by simple and easy repairerment.When measuring, in order accurately to read gage readings, operating personnel often need to bow and read measured value on the ground, therefore for the convenient reading that makes measuring instrument reads, can raise the height of pointer, simultaneously corresponding adjustment scale is provided with the position, with the scale translation that makes progress, the height H of raising of pointer equals the distance R of sleeve bottom to sleeve 0 scale, as shown in Figure 3, so that measurement result can direct-reading, and need not to calculate.

The measurement floor may further comprise the steps:

1) on floor 9, bores a through hole that is a bit larger tham sleeve 1 diameter, through-hole diameter is about 1.2cm, and analyzer pull bar 2 is promoted downwards, then measures the flexible of piece 6 down and cranks arm along with the movement and deformation of pull bar 2, as shown in Figure 4, until making the through hole of cranking arm by floor;

2) will measure piece 6 down and stretch out the floor through hole fully after, with upwards pulling of pull bar 2, the flanging of cranking arm is against on floor 9 lower surfaces, expands into an isosceles triangle, the base flushes with the lower surface of floor 9, as shown in Figure 1;

3) measure the effect of piece 5 on the analyzer, be pressed on floor 9 upper surfaces, floor is clamped automatically, reduced the use of manpower because of spring hold-down devices 3.

4) show according to pointer, the slab thickness reading.

Only need when 5) taking out pull bar 2 is promoted downwards, the isosceles triangle of expansion is out of shape after, hold sleeve 1 and upwards pull out and get final product.

Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
