Background technology
At present, when measuring the empty cutter spacing of ampuliform workpiece bottleneck, the measurer of measuring the internal orifice dimension size adopts vernier caliper, internal calliper usually, and the as a result precision that vernier caliper and internal calliper are measured is high, but uses the vernier caliper expense high, uses the internal calliper reading inconvenient.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of reading bottle mouth of gas cylinder inner diameter gauge simple, easy to use.
In order to solve the problems of the technologies described above, the utility model provides a kind of bottle mouth of gas cylinder inner diameter gauge, it comprises two sounding rods that connect by bearing pin, respectively the first sounding rod and the second sounding rod, the first sounding rod has the first measuring junction in the front side of bearing pin, the second sounding rod has the second measuring junction in the front side of bearing pin, the first sounding rod is fixedly connected with display board at the rear side of bearing pin, there is scale mark in the display board front, the second sounding rod rear end is fixed with pointer, pointer is mobile above the front of display board, and pointer does not contact display board.
Adopt this structure, the first measuring junction and second measuring junction of the first sounding rod and the second sounding rod front end are extended bottle mouth position, regulate the first sounding rod and the second sounding rod, make the first measuring junction contact respectively the bottleneck inwall with the second measuring junction, and at bottleneck maximum displacement arranged in the radial direction, the first sounding rod forms with the second sounding rod and intersects, the pointer that drives the second sounding rod rear portion is mobile at display board, determine the size of bottleneck by being set in reading above the display board before the pointed, mainly utilize the similar triangles rule, for the less number of dimensional tolerance range of measuring, be unfavorable for reading, can amplify at display pole and show multiple, handled easily personnel observation.
In order better to understand technology contents of the present utility model, below with the bottle mouth of gas cylinder inner diameter gauge referred to as this measurer.
Also be provided with limited post on the display board of this measurer, limited post is fixedly connected on the displaying plate face away from a side of the first sounding rod; Also be fixedly connected with baffle plate on the second sounding rod, baffle plate moves in the lower rear of display board, and baffle plate does not contact display board, and the height of limited post is greater than the distance of baffle plate to displaying plate face.
Adopt such structure, cooperate with limited post by baffle plate, it is mobile in the display board zone to limit pointer, is unlikely to the pointer difficulty that can not reset or reset when using next time, and reduces the error that the wearing and tearing of pointer is caused reading.
On the display board of this measurer screw is arranged; Described limited post is caging bolt, and caging bolt matches with screw on the display board, adopts such structure, makes the assembling of caging bolt and display board more convenient.
Between first sounding rod of this measurer and the second sounding rod torsion spring is arranged, torsion spring is so that two sounding rods when static, form maximum angle between the first sounding rod and the second sounding rod, and after each use, the first sounding rod and the second sounding rod all can return to maximum angle, so that more convenient operation.
Description of drawings
Fig. 1 is the front elevation of this measurer embodiment.
Fig. 2 is the stereographic map of this measurer embodiment.
Embodiment
Shown in Fig. 1 to 2, the utility model bottle mouth of gas cylinder inner diameter gauge comprises the first sounding rod 1 and is connected sounding rod 2 by bearing pin 10 connections, the first sounding rod 1 has the first measuring junction 9a in the front side of bearing pin 10, the second sounding rod 2 has the second measuring junction 9b in the front side of bearing pin 10, the material of the first measuring junction 9a and the second measuring junction 9b all is YW type wimet, the fixing riveted joint in the rear portion of the first sounding rod 1 has display board 7, there is scale mark 8 in display board 7 fronts, the second sounding rod 2 rear ends are welded with pointer 5, the second sounding rod 2 has bending part 3 between pointer 5 and bearing pin 10, so that pointer 5 is mobile above the front of display board 7, pointer 5 does not contact display board 7, on the display board 7 screw is arranged, screw is in the side away from the first sounding rod 1, caging bolt 6 matches with screw on the display board 7, baffle plate 4 is by fixedly being riveted on the second sounding rod 2, baffle plate 4 covers pointer 5 in display board 7 rear projections in display board 7 rear projections, baffle plate 4 is mobile between the first sounding rod 1 and caging bolt 6, baffle plate 4 does not contact display board 7, the screw rod of caging bolt 6 stretches out the distance at display board 7 back sides greater than the distance between baffle plate 4 and display board 7 back sides, cooperate with caging bolt 6 by baffle plate 4, it is mobile in display board 7 zones to limit pointer 5, being unlikely to pointer 5 can not reset when using next time or reset difficulty, and reduction causes the error of reading to the wearing and tearing of pointer 5, between the first sounding rod 1 and the second sounding rod 2 torsion spring 11 is arranged, when static, keep maximum opening angle between the first sounding rod 1 and the second sounding rod 2.
