Description
Technical field
The utility model relates to a kind of chi tool, especially surveyor's staff technical field.
Background technology
Surveyor's staff is the survey instrument that be unable to do without commonly used in people's daily life, uses in occasions such as building, machinery installation, carpenters.The surveyor's staff that uses uses the aluminium section of hollow to do the chi body usually now, open circular hole or slot on the chi body, settle garden dish type bubble seat in the hole, in the bubble seat air level is arranged, air level is divided into horizontal levelling bubble, vertical air level and 45 degree air levels, the chi end of body is packaged with plastic end cover, traditional air level is not have the measuring accuracy micro-adjusting mechanism, this is to have some shortcomings, has certain deviation as machining, when parts install, also can there be some errors, if do not regulate correctly, system errors for measurement after these errors will become causes bad influence; Air level all regulates when dispatching from the factory on the other hand, meets the requirements, the long-time use, and metal chi body is heated or stress deformation in use, also can cause air level to produce deviation, causes the error in the measurement.There are scientific and technical personnel to develop new surveyor's staff with air level fine tuning structure for this reason.As the patent No. is 00217890.7 Chinese patent " surveyor's staff ", it includes chi body, bubble seat, end cap, be respectively arranged with 180 degree bubbles, 45 degree bubbles, 90 degree bubbles on the chi body, it is characterized in that being provided with bubble near end position at the chi body, end cap on its bubble and the fixed ruler end of body fuses by plastic fastening, and, being installed with the spring that withstands between bubble seat and the end cap on the self-tapping screw with two self-tapping screws connections up and down, the screw hole on the end cap clogs with stopper.It is owing to designing micro-adjusting mechanism near on the bubble seat of end caps, can oneself suitably adjust the measuring accuracy of this bubble, has certain technical progress, but the bubble at place does not still have micro-adjusting mechanism in the middle of surveyor's staff usually, can not finely tune adjusting, bring the inconvenience of installing simultaneously, because perforate and the injection mo(u)lding of bubble seat all have the dimensions error on metal chi body, one of impossible percentage hundred is correct, exist indefinite slight clearance so cause the bubble seat to install at the chi body, also need to adjust according to actual conditions, and former surveyor's staff does not have the Design of Mechanical Structure of this respect, cause inconvenience and the systematic error installed, so the weak point of existing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of surveyor's staff at prior art, and it is to also finely tuning adjusting at the air level of chi body middle part, and the chi measuring accuracy of both having improved the standard can make things convenient for it to produce again and go up the manufacturing assembling.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind surveyor's staff, it includes chi body, bubble seat, end cap, adopt the shape of hollow to do the chi body, and on the chi body, open a plurality of holes, multiple bubble seat has been installed, and the end portion encloses of chi body has end cap, it is characterized in that being connected with the locking frame in the horizontal bubble seat bottom of chi body middle part by the plastics connecting portion, locking frame sidepiece has crossed bolt, and bolt head is screwed with nut.
Above-mentioned locking frame its up and down edge be straight, and the side edge is to be outer convex or evagination triangle.
Compared with prior art, advantage of the present utility model is: the air level of the middle part of chi body has fine tuning structure, can carry out suitable self-adjusted size, make surveyor's staff chi body very convenient when centre bubble seat is installed, inconvenience in the assembling that the scale error that can avoid making is brought, the error of simultaneously also having avoided air level to install, improved the surveyor's staff measuring accuracy, and adjustment structure is very simple effectively, cheap for manufacturing cost, on producing, implement easily, have very strong practicality.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.
Anticipate as shown in the figure, this kind surveyor's staff, it includes chi body 1, bubble seat 2,8,9, end cap 11, adopts the shape of hollow to do chi body 1, as adopt aluminium section, and on the chi body, open a plurality of holes, and open circular hole at chi left end position, the vertical bubble seat 8 of 90 degree is installed on this circular hole, in the bubble seat bubble is arranged, the bubble seat adopts injection molding to come out, and has micro-adjustment structure, does not temporarily say to ask for an interview here to describe below.Chi body middle part has slot 7, measure for convenience, this slot is opened at chi body upside position, form three observation panels, this slot has been installed the horizontal bubble seat 2 of 180 degree, bubble is also arranged in the bubble seat, install and eliminate error for convenience, this horizontal bubble seat bottom is connected with locking frame 4 by plastics connecting portion 3, and bolt 5 has been crossed in perforate in the middle of the locking frame sidepiece, bolt head is screwed with nut 6, in order to play good locking effect, the locking frame 4 about edge be straight, help with the chi body inside entirely contact, and the side edge is to be outer convex or evagination triangle, by turning nut 6, make suitably evagination of locking frame 4 edges like this, make edge tensioner up and down, horizontal bubble seat 2 of assurance and chi body 1 link into an integrated entity, and improve the precision that this bubble is measured simultaneously.In order to make its plastics connecting portion keep good flexibility, can regulate well, it is good that this plastics connecting portion 3 is short cylindrical.Also have circular hole at chi body 1 right-hand member position, 45 degree bubble seats 9 have been installed on this circular hole, this bubble seat links into an integrated entity by plastics connecting portion 10 and end cap 11, have corresponding last screw and following screw 14 between bubble seat and the end cap, be screwed with set screw 12 in their screws, be installed with spring 13 on the set screw, spring is supported between bubble seat and the end cap, and screw clogs with stopper 15 on the end cap.This end cap is encapsulated on the end of chi body, in order to make this plastics connecting portion keep certain flexibility and rigidity, this plastics connecting portion is to adopt the circle structure connecting end caps, to keep suitable necessary rigidity, and connect bubble seat place is the short column shape, to keep good flexibility, to regulate to help its trace, whole plastic components can adopt injection mo(u)lding.
Its principle of work is such, when horizontal bubble seat 2 puts in from the perforate of chi end of body, 7 places stop when middle slot, regulate tightening nuts 6 then, make the 4 side drawdown deformations of locking frame, edge gets up with regard to lifting like this, drives horizontal bubble seat 2 and rises, up to the chi body 1 and fixing that rises, if this moment, the air level error was excessive, undesirable, can make air level reach claimed range by the opening deviation corresponding position above the extruding chi body; In the time will regulating the bubble seat 9 of chi end of body,, an end cap 11 and a side spacing of bubble seat 9 are changed as long as turn screw 12, thereby driving bubble seat 9 reverses to a side, realization is adjusted the setting angle trace, eliminates systematic error, improves the measuring accuracy of this air level.
