Abstract
The utility model discloses a self-brake band tape, belonging to the band tape technical field of measurer. The utility model comprises a casing 1 which spindle is sheathed by a ruler core 2 coiled with a ruler band 4, wherein the end of the ruler band extruded outside the casing is connected with a ruler hook 8, a ruler spring 3 is connected between the ruler core 2 and the spindle of the casing 1, and the casing is provided with an element for automatically braking the ruler band, therefore, the drawn ruler band can automatically stop without braked by button to make measurement easy. And when retracts the ruler band, user only needs to press down the button to retract the ruler band via the elasticity of the ruler spring.
Description
Technical field
The utility model relates to the technical field of tape measure in a kind of survey instrument.
Background technology
Tape measure is a kind of dimensional measuring instrument commonly used, because advantage such as volume is little, and is easy to use has become one of indispensable instrument of family and workplace.By having or not locking key can be divided into two kinds, a kind of is the brakeless tape measure, needs after promptly the chi band is pulled out to unclamp the chi hook gauge and take back receipts with chi hook or hand fixed ruler band; Another kind is that the braking tape measure is arranged, and can brake the chi band with button after the chi band is pulled out, and chi is taken back receipts behind the release button.What sell in the market mainly is that the braking tape measure is arranged, and need bring inconvenience to the user through hand propelled button commonly used during use.
Summary of the invention
Technical problem to be solved in the utility model be can Braking mode at prior art and after providing a kind of chi band to pull out tape measure.The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of self-retention tape measure, it comprises housing, be with the chi core on the mandrel of housing, be wound with the chi band on the chi core, the chi band stretches out the housing outer end and is connected with the chi hook, be connected with the chi spring between chi core and the housing mandrel, it is characterized in that enclosure interior installed the parts of Braking mode chi band.
The parts of described Braking mode chi band comprise button and brake block.Button is socketed on the pillar of enclosure interior, and its front end cooperates with brake block.The brake block head coats resilient material, one end mounting spring, and two sides are fluted, behind the convex tendon on the embedding housing on the relevant position, can slide up and down along the gradient direction of convex tendon.When pulling out the chi band, because the relativity power that brake block head and chi band exist, brake block upwards slides along the gradient of convex tendon, and this moment, the chi band can freely be pulled out; After unclamping the chi band, the relativity power that same because brake block head and chi band exist, brake block along the gradient of convex tendon to lower slider, thereby compress the chi band, the chi band is stagnated no longer recovery.When needing to regain the chi band, press the button, button turns clockwise around pillar, and the button front end is upwards stirred brake block along the gradient of convex tendon on the housing, and this moment, the chi band can freely be regained.
Compared with prior art, after advantage of the present utility model is to pull out the chi band, need not be convenient for measuring with hand propelled button braking chi band.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model embodiment, and Fig. 2 is the cut-open view of chi band brake structure.
Embodiment
Below in conjunction with accompanying drawing embodiment the utility model is done and to be described in further detail
As Fig. 1, shown in Figure 2, be a preferred embodiment of the present utility model.Self-retention tape measure in the present embodiment, it includes housing 1, is with chi core 2 on the mandrel of housing, is wound with chi band 4 on the chi core 2, and the chi band stretches out the housing outer end and is connected with chi hook 8, is connected with chi spring 3 between chi core 2 and the mandrel; Button 10 is socketed on the pillar 11 of housing 1, and its front end cooperates with brake block 5 relevant positions, and brake block 5 both sides are fluted, cooperates with the diagonal bar 6 of projection on the housing 1.When chi band 4 was pulled out, its reacting force to brake block 5 made it to overcome the slight resistance of an end spring 9, upwards slided along the diagonal bar on the housing 17, no longer compressed the chi band, and chi band 4 can freely be pulled out at this moment.Pull out stop after, chi band 4 relies on the chi spring 3 that is connected between chi cores 2 and the mandrel that withdrawal trend is arranged, and its reacting force to brake block 5 makes it along the diagonal bar on the housing 17 to lower slider, by with housing 1 on compress chi band 4 after boss 6 actings in conjunction that are provided with, this moment, the stagnation of chi band was motionless, was convenient for measuring; After finishing to measure the chi band is regained, be pressed the button 9, the pillar 10 on housing 1 turns clockwise, and its front end is upwards stirred brake block 5 along the diagonal bar on the housing 17, removes the snap-in force to chi band 4, and this moment, the chi band relied on the elastic force of chi spring 3 to regain.
