Description
Technical field
The utility model relates to a kind of tape measure that has detent, and this stopper mechanism can be realized the automatic one-way locking braking to chi core dish.
Background technology
In the prior art, be located on the tape measure the chi band brake how in the following way, that is, after the chi band pulled out from housing, detent is operated, the chi band is stopped on its position that is drawn out.Wherein, the chi band brake also has the mode that automatically locks that adopts, when this mode of employing, on the position after can making the chi band stop at it automatically to be drawn out from housing.This mode of automatically locking has following form, that is, along the chi core dish that the rollback direction of chi band is endowed potential energy the chi band is stopped by braking; Perhaps, directly to the chi band brake that stretches out from chi core dish the chi band is stopped by stop part.Though adopt the latter's method braking rapid, very strong to the infringement impact big, when the chi band stops of chi band printing surface; In the prior art, also have and adopt ratchet one-way brake chi core dish, adopt this method on chi core dish, corresponding ratchet to be set, and it is stronger to the impact big, when the chi band stops of chi core adjustment debit evil when braking, and, pull out in the process at the chi band, ratchet ratchet interlock noise is bigger, has bigger resistance simultaneously when the chi band is pulled out.
Summary of the invention
Goal of the invention of the present utility model, be to provide a kind of tape measure that has detent, by being set in housing, unidirectional wedge fastening type detent realizes the auto lock of chi core dish is braked, pull out in the process at the chi band, detent discharges automatically, make pulling of chi band and chi core dish rotate the resistance that can not be subjected to from detent, when the chi band has backrush trend, the detent Braking mode, make chi core dish can't rotate back tape band, in the time will regaining the chi band, the manual release detent makes chi core dish can rotate back tape band.Adopt the wedge fastening type braking can avoid problems such as the big and resistance of the noise of pawl type braking is big.
The utility model is achieved by following technical solution:
A kind of tape measure that has detent comprises housing, rotates in the housing chi core dish is set, and is wound with the chi band on the chi core dish, and described chi core dish is connected with backrush actuating unit and turning stopper, and described turning stopper comprises at least:
One is used for chi core dish is applied the arrestment mechanism of braking;
One gives the potential energy mechanism of potential energy all the time to arrestment mechanism towards braking direction;
One can operate the brake service mechanism of brake off from hull outside;
One connects the bindiny mechanism of arrestment mechanism and brake service mechanism; Wherein,
Described arrestment mechanism comprises and is fixed to parts and engaging part that the described parts that are fixed to are fixed between chi core dish and the engaging part, and chi core dish is braked on chi core dish backrush rotation direction.
Below the utility model is elaborated, described housing is meant takes in the parts of measurement with the chi band, it also is the main body of tape measure, housing is made of the resin material that forms desirable shape, vertically be provided with the chi mandrel on the sidewall in this housing, hinged on the chi mandrel have a chi core dish, reeling around this chi core dish and printing graduated measurement chi band; In addition, be provided with the backrush actuating unit (being generally volute spring) that is used for rollback chi band in the inside of this chi core dish, the chi band is endowed potential energy towards the direction of rollback thus; Housing normally utilizes the good resin material of formability to be shaped integratedly, utilizes other material such as metal material to form housing but also have.
On position such as above this housing front side, be provided with brake service mechanism in the mode that can operate from hull outside, arrestment mechanism is connected by bindiny mechanism with this brake service mechanism, is used for the chi band application is added braking.This bindiny mechanism comprises that one can be around the support of stationary shaft rotation, support is fixed to parts in the far-end connection that departs from stationary shaft, on chi core dish backrush rotation direction, gap between described chi core dish and the engaging part diminishes gradually, described potential energy mechanism is fixed to parts and is connected with support to the mode that described gap small end moves to impel all the time, and described brake service mechanism is fixed to parts and is connected with support to the mode that the big end in described gap moves impelling.Employing can setting be fixed to parts on the support that stationary shaft rotates, can guarantee to be fixed to effectively being fixed to of parts and chi core dish and engaging part, and, improved the comfort of tape measure because leverage only needs just can discharge detent by less power.
Above-mentionedly be fixed to the transmission arm end that parts can be set directly at support, in order to guarantee that being fixed to parts can be fixed to preferably between engaging part and chi core dish, avoiding support to bear big stress because of site error causes and breaks, so the transmission arm that above-mentioned support setting is fixed to parts can be done camber, not rupture to bear big stress.In like manner, can also be with a transmission arm end articulated linkage of above-mentioned support, on connecting rod, be provided with and be fixed to parts, having guaranteed to be fixed to parts like this can be movable among a small circle, make its can the self-adaptation adjustment better to be fixed between engaging part and chi core dish.Here said be fixed to be meant parts clamp-on the chucking be fixed between chi core dish and the engaging part.
The above-mentioned parts that are fixed to can be made by hard material, and can produce to a certain degree elastically-deformable wedge; Certainly, preferably make rotary roller shape, like this, when its periphery with chi core dish contacts,, reduced the resistance that the chi band is pulled out, and when braking, roller can stop operating and be fixed between engaging part and chi core dish equally for the contact of rolling.In order to improve retro-speed and effect, can change the roller surface characteristic to increase friction force, for example the surface is provided with any of projection, prominent bar, groove or asperities or their combination in any; Equally, also can be provided with spline structure to increase friction force in the peripheral surface of above-mentioned chi core dish; In addition, can also for example the bipassage ring connected in star be set, make the chimeric rubbing contact of periphery of annular groove and chi core dish by increasing surface of contact to increase friction force on the above-mentioned rollers surface.
