Abstract

The invention discloses a kind of length Halver gauge, it belongs to measurement apparatus field, the Along ent accurate positioning that it can be to length or angle, easy operation.The technical proposal of the invention is realized in this way, and two are faced foot lever of the moulding such as bicycle chain in the symmetry shape office left and right sides, and left and right foot lever is combined in the hole of the circular portion overlapped each other by bearing pin through two foot lever lower ends；The shell fragment of an approximate V-arrangement is all sticked into the space of the bearing pin left and right sides, outer one side of two shell fragments is all linearly and is in contact with the inwall of foot lever, the semicircle arcuation for bearing pin of fitting then all is processed at the position being in contact with bearing pin for inner one side of two shell fragments and two sides are adjacent to each other near the line of symmetry of left and right foot lever, while device has the mark post that a structure is telescopic Sopwith staff shape between this two sides；There are two regulating bolts in the device of symmetry on the two sides position being in contact with shell fragment of left and right foot lever.

Description

Length Halver gauge

Technical field

The invention belongs to survey tool field, a kind of length Halver gauge is specifically referred to.

Background technology

Intermediate point is found out in a segment length or an angle is intended to be divided into two angles etc. in mapping operation, product or work Often to be used in the processing and making process of skill product, the method that usual people use is that have or advise tool measurement line with chi to find out, Time-consuming effort effect low inconvenience during concrete operations；If the product of the fixed length of unified processing finds out midpoint to facilitate under progress What one procedure was relatively easy to, but often part and random length in the operation of reality, frequently switched to find out midpoint The way of frock tool is certainly inconvenient, and the punching whether being accurately positioned to next step of intermediate point or other manufacturing procedures have Important influence, so, a kind of easy to operate intermediate point that faster can find out a segment length of simple structure or one The bisecting line of angle hand-held rule tool can meet people it is this in the urgent need to.

The content of the invention

The purpose of the present invention is to provide a kind of new technical scheme length Halver gauge of survey tool, and it can be solved The problem of stating.

The technical proposal of the invention is realized in this way, and two are faced foot lever of the moulding such as bicycle chain in symmetry shape Left and right foot lever is combined one in the office left and right sides, the hole of the circular portion overlapped each other by bearing pin through two foot lever lower ends Rise；All stick into the shell fragment of an approximate V-arrangement in the space of the bearing pin left and right sides, outer one side of two shell fragments it is all linearly and It is in contact with the inwall of foot lever, inner one side of two shell fragments is then all processing bearing pin of fitting with the position that bearing pin is in contact Semicircle arcuation and two sides are adjacent to each other near the line of symmetry of left and right foot lever, while device has a structure between this two sides For the mark post of telescopic Sopwith staff shape；In the device of symmetry on the two sides position being in contact with shell fragment of left and right foot lever There are two regulating bolts.

The beneficial effects of the invention are as follows that can be two parts to length or angle bisecting, Along ent be accurate, and operation is simple fast It is prompt.

Brief description of the drawings：

Fig. 1 is the Halver gauge of the design citing in the front view for closing up shape.

Fig. 2 is in the front view for opening shape.

Fig. 3 is the loose mail detailed view before each part is fitted together.

In each figure, 1 is foot lever, and 2 be mark post, and 3 be shell fragment, and 4 be regulating bolt, and 5 be bearing pin.

Embodiment：

Illustrate the design below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, Figure 3 shows, cut out with sheet metal by punching press and expect that folding holds into symmetrical two and faces moulding Foot lever 1 such as bicycle chain, its lower end is approximate circle, and there is connecting hole at center, and the circle overlapped each other is passed through by bearing pin 5 The connecting hole of shape part combines left and right foot lever；All sticked into space between bearing pin 5 and left and right foot lever two sides The shell fragment 3 of the same specification of one approximate V-arrangement, outer one side of two shell fragments is all linearly and is in contact with the inwall of foot lever, and two Inner one side of shell fragment then all processes the semicircle arcuation moulding and two for the bearing pin that can fit at the position being in contact with bearing pin 5 Bar side is adjacent to each other near the line of symmetry of left and right foot lever, as illustrated, so then shell fragment and bearing pin can reliably be blocked from And the stability of its setting position is kept without displacement easily, there is the structure to be while going back firm joint device between this two sides A variety of methods such as insertion or clamping, spot welding may be selected in the mark post 2 of telescopic Sopwith staff shape, affixed mode, and the structure of Sopwith staff is The assembly of the more piece gradient-thickness of rectangular in cross-section, it has scalability, can elongate or shorten according to needs；In left and right foot lever Also two regulating bolts 4 of device of symmetry on the two sides position being in contact with shell fragment, the inner termination of bolt with Shell fragment is in contact, and the big minor adjustment of the pressure thereby applied to shell fragment can be to there occurs that mark post refers to large deviations during use Phenomenon carries out accurate correction regulation.In specifically used, the opening of foot lever 1 is opened according to the size of middle part or length dimension is looked for Open, such as Fig. 2 shapes, the bar point of left and right foot lever is respectively directed to two ends or overlapped with angle line, and elastic force is resisted in a balanced way by two shell fragments The size mark post of control opening angle all can the i.e. bisection of length or angle on the line of symmetry in two foot levers all the time On line, so as to accomplish quickly accurately to look for middle operation, using can be by regulation if finding that mark post refers to large deviations after a period of time Bolt carries out accurate regulation correction, simple and convenient；When two foot lever opening angles are larger, it is found that the paracone position phase of mark post It is many for having gone out before the line at two foot levers tip, now need mark post suitably to bounce back and look for middle observation and process to grasp to facilitate Make, and the design feature of Sopwith staff can meet this needs, and the extension elongation of mark post can be adjusted according to concrete condition, in addition also can be according to this The general principle of design is that " elastic resistance means its identical space hold to adjacent shell fragment in a balanced way " designs trisection The fourth class is graded apparatus.Along ent accurate positioning of the present invention to length or angle, easy operation is association area operator The capable good assistant of member.

Claims
