Abstract

The utility model discloses a flexible rule which belongs to the technical field of the measuring tool, comprising a rule body, a rule spring, and a rule belt. The utility model is characterized in that two fixed axles are arranged between the rule casing; the two axles are respectively connected with a gear; the rule spring, the rule belt are respectively coiled on the two fixed axles; the gear of the two fixed axles are in an engaging transmission state by a gear. The flexible rule provided by the utility model is provided with double fixed axles; the rule belt and the rule spring are respectively coiled with two fixed axles. The long roll type rule belt can be stored, and meanwhile, the holding and carrying are convenient. The flexible rule is transmitted by the gear, with the advantages of steady and uniform rule belt retraction, and small noise, etc.

Description

A kind of tape measure
Technical field
The utility model belongs to the measuring tool technical field, and relating to a kind of inside is gear-driven tape measure.
Background technology
Tape measure generally is made of chi shell, chi core, chi spring and chi band as a kind of survey instrument commonly used, and the chi tape wrapping is also installing on the reel in the chi shell, and its effect of the spring of chi in-core is will be retracted to the outer chi band of chi shell to be withdrawn in the chi shell with elastic force.The distance that the chi band is pulled out the chi shell determines the size of chi spring force and the speed that chi is taken back receipts, this hinders hand with regard to the excessive velocities that becomes to reclaim when pulling out chi shell long enough when the chi band, accomplish when tape measure that certain specification size chi band is crispaturaed with the chi spring simultaneously and be in the same place the excessive defectives such as holding inconvenience that causes of its volume.
Summary of the invention
The utility model is taken back the deficiency of receipts at the limited and chi of the tape band of above-mentioned single shaft core of the prior art, provides a kind of gripping convenient, and chi is taken back and received tape measure stably.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of tape measure comprises chi shell, chi spring and chi band, establishes two dead axles between it is characterized in that in the chi shell, and two dead axles are connected with gear respectively, and chi spring, chi band are set around two dead axles respectively, and two fixed axis gears are by Jie's meshed transmission gear.
Described two dead axles lay respectively at portion about the chi shell, and bearing is located at chi shell two inboards, covers assembling.
Jie's gear and two fixed axis gear engaged transmission, Jie's gear are fixed on the parallel minor axis of two dead axle axial connecting lines, and Jie's gear is less than two fixed axis gears.
Establish one or two ratchet in the chi shell, ratchet and braking knob lockable fixed axis gear.
The tape measure that the utility model provides, chi band and chi spring be not on same axle, be provided with a pair of stationary shaft that parallels in the chi shell, the chi band twists in and is inserted in out on the chi mouth place axle on the chi axle (core), the chi spring twists in another chi axle (core) and is inserted on another axle, and chi axle (core) position of chi band, chi spring respectively is fixed with a gear, and the utility model adopts two chi cores that chi band and chi spring are set around dead axle respectively, can store the chi band of putting long paper, and can grip simultaneously carry convenient;
Be provided with Jie's gear in chi band gear and the chi spring gear, Jie's gear be fixed in one with the minor axis of the chi tape spool heart, chi spring axis parallel on, three gear teeth merge and compress.
Simultaneously, ratchet can be set in chi shell bottom and realize unidirectional and two-way locking fixed axis gear better with the braking knob.
Chi roll coil of strip wheel and chi spring rolling wheel be by Jie's gear drive, gear-driven mechanical property make tape measure of the present utility model have chi take back contract steadily, evenly, beneficial effect such as noise is little.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1
Tape measure of the present utility model as shown in Figure 1, establish two dead axles (2,3) between in the chi shell 1, two dead axles (2,3) are connected with gear (4,5) respectively, chi spring, chi band are set around two dead axles respectively, be that the dead axle (core) that the chi band curls is a chi band dead axle (core) 2, the dead axle that the chi spring curls is a chi spring dead axle (core) 3, and gear mesh fixing on same two dead axles should be chi band gear 4 and chi spring gear 5.Two fixed axis gears (4,5) are by Jie's gear 6 engaged transmission.
Portion about two dead axles (2,3) lay respectively in the chi shell 1, bearing is located at chi shell two inboards, covers assembling.
Jie's gear 6 and two fixed axis gears (4,5) engaged transmission, Jie's gear 6 is fixed on the parallel minor axis of two dead axles (2,3) axial connecting line, and Jie's gear 7 is less than two fixed axis gears.
Chi spring dead axle 3 is fixedlyed connected with chi spring gear 5, and chi band dead axle 2 is fixedlyed connected with chi band gear 4; Jie's gear 6 and chi shell 1 axis hole are connected, gear drive between chi band gear 4 and chi spring gear 5 and Jie's gear 6.Chi spring dead axle 3 drives chi spring gear 5 by 6 transmissions of Jie's gear, and chi band gear 4 drives chi band dead axle 2, and the chi band is steadily bounced back.
