Abstract

The utility model discloses a jointing rule comprising a rule body and a rule frame which are in slide fit with each other as well as a display on the rule frame, wherein an extension spring or a compression spring is arranged between the rule body and the rule frame, and when the spring is in a free state, one end of the rule body extends out of the end of the rule frame at one side corresponding to the end of the rule body; when the spring is in a state of extension or compression, which is greater than extension amount, the end of the rule body can retract into the end of the rule frame at the side; the end of the rule body and the end of the rule frame are provided with flaky measuring heads which are in the same direction and vertical to sliding direction and the display returns to zero when the end surfaces of the two measuring heads are parallel and level; and the display is an indicating gauge reading device, or a vernier reading device or a digit display reading device. The jointing rule integrates the function of measuring difference of height with the function of measuring jointing size into one body and has simple structure, complete functions and convenient use and portability.

Description

Rank seam rule

(1) technical field:

The utility model relates to survey instrument, specifically is a kind of rank seam rule.

(2) background technology:

In manufacturing, particularly automobile manufacture industry often needs the external appearance quality of inspection vehicle.For example check difference of height between automobile section adjacent two stepped surfaces (be called for short jump or section is poor), with the gap size between adjacent two outside surfaces of slit rule inspection with jump rule (also claiming a section difference rail).But existing jump rule can not be checked the gap size between adjacent two outside surfaces, and slit rule can not be checked the difference of height between adjacent two stepped surfaces, the checker need be equipped with jump rule and slit rule simultaneously, just can finish above-mentioned work, to carrying and use is made troubles.

(3) utility model content:

At the limitation of above-mentioned jump rule and slit rule use, the purpose of this utility model has provided a kind of with two kinds of function collection rank seam rule all over the body.

Can realize the rank seam rule of above-mentioned purpose, comprise the blade and the chi frame that are slidingly matched, and the display on the chi frame, different is to be provided with to stretch or compression spring between blade and chi frame, when spring is in free state, one end of blade stretches out outside the chi frame end of place one side, and when spring was in greater than the stretching of overhang or compressive state, this end of blade slidably was retracted in the chi frame end of this side; Described blade end and chi frame end are provided with in the same way and perpendicular to the gauge head of glide direction, display made zero when two gauge head end faces were concordant, the blade gauge head is stretched overhang outside chi frame gauge head and is added that the thickness of chi frame gauge head can measure the gap size between adjacent two outside surfaces, and contract amount of recovery in chi frame gauge head of blade gauge head can be measured difference of height between adjacent two stepped surfaces.

Less as measured slit, then the gauge head shape that should fry batter in a thin layer is beneficial to gauge head and inserts in the slit.

Laminar gauge head is flexible connection (screw is connected), fixedly connected (welding or riveting connect) or one-piece construction (whole machine-shaping) form with the connected mode of blade, chi frame.

Display can adopt dial gauge reading device commonly used, vernier reading device or numeral to show reading device.

Advantage of the present utility model:

The utility model rank seam rule integrate difference of height measures and slot measurement, simple in structure, multiple functional, easy to use and carry.

(4) description of drawings:

Figure 1 shows that the structural representation of a kind of embodiment of the utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the left view of Fig. 1.

Figure number sign: 1, blade; 2, chi frame; 3, display; 4, gauge head; 5, the chi frame is surveyed pin.

(5) embodiment:

The utility model rank seam rule comprise blade 1, chi frame 2 and are located at display 3 on blade 1 front, the chi frame 2 that display 3 be a numeral demonstration reading device, as Fig. 1, Fig. 2, shown in Figure 3.

In Fig. 1, Fig. 2, offer straight trough on the chi frame 2, in an end of chi frame 2, along trough rim always, chi frame 2 parts extend to form the chi frame forward and survey pin 5, and blade 1 is slidingly fitted in chi frame 2 straight troughs, and display 3 is installed on the chi frame 2, and is spacing to blade 1 at frontal.

Offer the groove of glide direction on blade 1 bottom and the chi frame 2 straight trough faces, be provided with extension spring in the groove, the two ends of extension spring are connected with chi frame 2 with blade 1 respectively, when making extension spring be in free state by setting, the measuring junction of blade 1 stretches out chi frame 2 outside the chi frame is surveyed pin 5, and extension spring is when being in extended state and tensile elongation greater than the overhang of blade 1 measuring junction, and blade 1 measuring junction slides retraction drilling depth frame 2 in the chi frame is surveyed pin 5, as shown in Figure 1 and Figure 2.

The measuring junction of blade 1 and chi frame are surveyed on the pin 5 with screw and laminar gauge head 4, two gauge heads 4 are installed perpendicular to glide direction and both are towards blade 1 back side, as Fig. 1, shown in Figure 3.

When the end face of two gauge heads 4 is concordant, position between blade 1 and the display 3 is made as zero point, numeral shows that reading device makes zero, the gauge head 4 that the gauge head 4 of blade 1 surpasses chi frame 2 is outside the time, numeral shows that the reading of reading device is set at "-" value, when the gauge head 4 of blade 1 was retracted in the gauge head 4 of chi frame 2, numeral showed that the reading of reading device is set at "+" value.

When measuring the slit with the utility model rank seam rule, the measurement result that numeral demonstration reading device shows also will add gauge head 4 thickness of chi frame 2, is only the full-size(d) in slit.
