Abstract
The utility model relates to a two-directional telescopic level ruler which comprises a main ruler, a water bubble seat and a water bubble component, wherein the main ruler is composed of a left-end body of the main ruler, a right-end body of the main ruler and a main body of the main ruler. The utility model is characterized in that the left-end body and the right-end body of the main ruler are respectively connected with a telescopic ruler which is fixed together with the left-end and the right-end bodies of the main ruler through screws, and the end of the telescopic ruler is provided with a limiting pin which is used for limiting the largest stretching length of the telescopic ruler; a balancing spring is arranged on the main body of the main ruler, and a followed balancing spring is arranged on the telescopic ruler and is used for keeping the gas and the tightness between the main ruler and the telescopic ruler. The utility model has the advantages of simple and reasonable structure, high precision and convenient carrying and storage, and can measure the degree of level and the verticality of long working surfaces.
Description
One, technical field
The utility model relates to a kind of surveyor's staff, specifically is a kind of bi-directional expansion surveyor's staff.
Two, background technology
Existing mean level chi length is fixed, and carries, deposits all convenient, flexible inadequately, and the length measured working range is less, to than the levelness of large working area, the measurement of verticality certain restriction being arranged; The unidirectional flexible surveyor's staff of Chu Xianing in the market, its structure is unreasonable, and collapsing length is big inadequately, and precision is also not high enough, and is elegant in appearance inadequately.
Three, summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, the bi-directional expansion surveyor's staff that a kind of novel structure, precision height is provided, is easy to carry and deposits.
Technical solutions of the utility model are as follows:
A kind of bi-directional expansion surveyor's staff, comprise main scale, bubble seat and bubble assembly, main scale is made of main scale left end body, main scale right-hand member body, main scale main body three parts, it is characterized in that: main scale left end body, main scale right-hand member body connect left shrinkage-rule, right shrinkage-rule respectively, left side shrinkage-rule and main scale left end body, right shrinkage-rule and main scale right-hand member body tighten together by screw respectively, in the shrinkage-rule end position-limitting pin are arranged.Position-limitting pin plays the qualification effect to the maximum length of the stretching of shrinkage-rule.
The utility model has balancing spring on the main scale main body, main scale main body and balancing spring are fixed together by pin, is used for keeping gap and elasticity between main scale and the shrinkage-rule.
The servo-actuated balancing spring is arranged, to assist gap and the elasticity between maintenance main scale and shrinkage-rule on the shrinkage-rule of the present utility model.
There is shrinkage-rule at surveyor's staff of the present utility model two ends, can about flexible, flexible maximum length is limited by position-limitting pin; Gap between main scale and shrinkage-rule and elasticity are regulated maintenance by balancing spring on the main scale main body and the servo-actuated balancing spring on the shrinkage-rule; The utility model is rational in infrastructure, the precision height, and flexible scope is big, is easy to carry and deposits the levelness of the longer workplace of energy measurement, verticality.
Four, drawing explanation
Fig. 1 is a structural representation of the present utility model, and wherein (1) is main scale left end body, and (2) are left shrinkage-rule, and (3) are the main scale main body, and (4) are right shrinkage-rule, and (5) are main scale right-hand member body, and (6) are position-limitting pin.
Fig. 2 is the utility model inner structure synoptic diagram.Wherein (7) are bubble seat and bubble assembly.
Fig. 3 is the utility model A enlarged drawing.Wherein (8) are cylindrical pins, and (9) are balancing spring.
Fig. 4 the utility model B enlarged drawing.Wherein (10) are the servo-actuated balancing spring.
Five, embodiment
Embodiment as shown in Figure 1, 2, the utility model comprises main scale, bubble seat and bubble assembly (7), main scale is made of main scale left end body (1), main scale right-hand member body (5), main scale main body (3) three parts, it is characterized in that: main scale left end body (1) connects left shrinkage-rule (2), main scale right-hand member body (5) connects right shrinkage-rule (4), left side shrinkage-rule and main scale left end body, right shrinkage-rule and main scale right-hand member body tighten together by screw respectively, and position-limitting pin (6) is arranged in the shrinkage-rule end.Position-limitting pin plays the qualification effect to the maximum length of the stretching of shrinkage-rule.
The utility model has balancing spring (9) on main scale main body (3), main scale main body (3) is fixed together by cylindrical pins (8) with balancing spring (9), servo-actuated balancing spring (10) is arranged on shrinkage-rule, be used for keeping gap and elasticity between main scale and shrinkage-rule.
Claims (3)
