Abstract
The utility model relates to an internal measuring hook which belongs to a length measuring instrument and is used for measuring the internal dimension. The utility model is a pair of symmetrical structure. The utility model is characterized in that a guide rod which can slide transversely is arranged at the upper end of a bracket, the guide rod can be fixed on the upper end of the bracket by a fastening screw, the external end of the guide rod is downwards and vertically extended to a measuring bar, a measuring head is positioned at the internal side of the lower end of the measuring bar, and a calibrating rod and a calibrating hole are respectively arranged at the two external side surfaces of the lower ends of the symmetrical measuring bars; thereby, the spacing which is formed from the measuring head to the bracket can be adjusted, the utility model is not limited by the external dimension of a measured workpiece, and the internal measuring hooks with a plurality of dimension are not needed. The utility model has the advantages of high measuring precision, simple structure, easy fabrication and convenient operation.
Description
The utility model belongs to the improvement that length-measuring instrument is used for the interior survey hook structure of inside dimension measurement.
Gauging machine in the present length measuring instrument, the bow-shaped structural that it is a pair of symmetry that horizontal length measuring machine, horizontal optical meter etc. are used for interior survey hook that inside dimension measures, because its arc measuring staff can not be regulated, when the wall thickness that runs into measured workpiece surpasses the length of bow, workpiece can not be stuck in the bow and measure, so need to be equipped with several different length of bows' interior survey hook; Survey hook in existing in addition and be with about survey top, hook outer face in two tongue and groove carry out coincidence correction, its precision is not high, error is bigger, is one of main source of measuring error, and is difficult to make.
The purpose of this utility model provides a kind of interior survey hook of improved adjustable dimension, and have calibration accurately, make simple advantage.
Surveying hook in designed is a pair of of symmetry, its structure is that the support upper end that can be connected and fixed connecting rod in the lower end is connected with measuring staff, inboard in the measuring staff termination is provided with gauge head, feature of the present utility model is, have guide rod hole in support upper end, be provided with the guide rod that can laterally slide in it, also being provided with trip bolt in the support upper end can location guide, be extended with measuring staff vertically downward at the guide rod external end head, gauge head is positioned at the inboard of measuring staff lower end.Feature of the present utility model also is, at two lateral surfaces of the measuring staff lower end of the interior survey hook of a pair of symmetry, one side is provided with calibrating stem, and another side is provided with calibration hole at correspondence position, and calibrating stem can insert in the calibration hole identically; The degree of depth of calibration hole should can make in two the measuring staff lateral surface of surveying hook be close together when calibrating stem inserts, and calibrating stem (7) and gauge head (8) are on same axis.
From such scheme as can be seen, the interior survey hook that the utility model is designed, its gauge head to the length distance between support can be regulated as required, is not subjected to the restriction of measured workpiece outside dimension, also need not be equipped with the interior survey hook of several sizes; In addition because calibrating stem and calibration hole are arranged on the lower end of measuring staff, with gauge head on same axis, and size is littler, so improved measuring accuracy, and has easy, simple in structure, the easy to operate advantage of making.
Accompanying drawing 1 is the designed interior structural representation of surveying hook (one of them) of the utility model, and accompanying drawing 2 is designed interior hook (symmetrical is a pair of) the measuring staff lower end partial structurtes synoptic diagram of surveying of the utility model.1 is trip bolt among the figure, and 2 is stationary links, and 3 is support, and 4 is trip bolt, and 5 is guide rod, and 6 is measuring staff, and 7 is calibrating stem, and 8 is gauge head.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, the designed interior survey hook of the utility model is a pair of symmetrical structure, one structure only is that support 3 upper ends that it(?) can trip bolt 1 in the lower end be connected and fixed connecting rod 2 have guide rod hole, be provided with the guide rod 5 that can laterally slide in it, also being provided with trip bolt 4 in support 3 upper ends can location guide 5, be extended with measuring staff 6 vertically downward at the guide rod external end head, gauge head 8 is positioned at the inboard of measuring staff 6 lower ends.Referring to accompanying drawing 2, in a pair of symmetry, survey two lateral surfaces of measuring staff 6 lower ends of hook, one side is provided with calibrating stem 7, another side is provided with calibration hole at correspondence position, and calibrating stem 7 can insert in the calibration hole identically, the degree of depth of calibration hole should can make the lateral surface of two measuring staffs 6 be close together when calibrating stem 7 inserts, and makes calibrating stem 7 and gauge head 8 on same axis.When making, gauge head and calibrating stem are made of one, one is long and the other is short, and perforate is got through on the same axis in symmetrical two measuring staff lower ends, and two gauge heads that one is long and the other is short are contained in the hole respectively, thus long stretching out becomes calibrating stem, and the short hole that makes in the hole becomes calibration hole.
