Description
Technical field
The utility model relates to a kind of measuring tools, more particularly, to a kind of band laser ranging function steel tape.
Background technique
Tape measure as a kind of measuring tool, it is wide, small in size, portable because of its measurement range the features such as, it is each to receive each row
Industry personage's likes.For the ease of using, the steel tape of laser ranging is had also appeared, such tape measure is often equipped with a brake
Structure, the braking when tape measure is pulled to measurement length avoid causing length to change because wind spring is shunk, and existing arrestment mechanism is logical
The friction crossed between brake component and tape is to achieve the effect that fixed ruler band, it is clear that when by frictionally securing tape, easily by ruler
The scale taken rubs off, and may also result in the bending of tape measure when firmly excessive.
For example, one kind disclosed " a kind of improved tape measure of arrestment mechanism ", notification number in Chinese patent literature
The components such as CN2535765, including shell, stop button, tape, spring, core disk, damping elastomer, when tape is drawn out progress
When measuring, and needing fixed, stop button is pressed downward, tape is pressed between dog point and damping elastomer, damped elasticity
By quality, soft and flexible material is made body, since the coefficient of friction between damping elastomer and tape is larger, same
Pressure under, the frictional force that it is generated between tape will be far longer than the frictional force generated on hard material, therefore only need
It will be with stop button under lighter pushing, so that it may generate sufficiently large frictional force and carry out fixed ruler band.The patent will be traditional hard
Friction between material and tape is adjusted to the friction between elastic material and tape, although reducing arrestment mechanism to tape table
The pressure in face, but still the scale in tape can be rubbed off.
Utility model content
The utility model is in order to which overcome the problems, such as the prior art easily causes tape scale-wearing, and providing one kind can be real
Now to the braking of tape and laser ranging steel tape that tape is not rubbed.
To achieve the goals above, the utility model uses following technical scheme:
A kind of band laser ranging function steel tape, including shell, main shaft, backplate, wind spring, tape and laser ranging sensing

Predetermined position geosynclinal block and backplate slot cooperate, and spine block is separated with ratchet, and third predetermined position spine block and geosynclinal block are unmated.Wind spring is set
In in tape, for withdrawing tape in shell, two circular plates are used to limit the running track of tape, avoid the occurrence of in shell
The case where portion's tape is interfered, on main shaft with backplate it is coaxial be added to a ratchet, be arranged on the backplate of close ratchet side
Several backplate slots, by the cooperation of slide switch on shell and ratchet and backplate slot, to control the rotation of main shaft, thus to ruler
Band is controlled, and when needing to extract tape out, switch is adjusted to the first predetermined position, spine block and ratchet cooperate, and tape can extract out
But it can not bounce back, avoiding maloperation causes tape to bounce back, when tape to required length, switch is adjusted to the second predetermined position,
Tape is braked, ranging is carried out by laser range sensor at this time, after being measured, switch is adjusted to third predetermined position,
Tape is withdrawn by wind spring elastic force, which is the braking by realizing tape to the control of main shaft, therefore will not be right
Tape causes to wear.
Preferably, the ratchet radius is less than backplate radius, the slide switch adjusts direction and radially sets along ratchet
It sets, the geosynclinal block top is in semi-cylindrical, and bottom is equipped with pressure spring, and the backplate slot radially has chamfering.Slide switch is arranged radially,
Spine block is in the form of a column, and improves stability, and geosynclinal block top is in semi-cylindrical, and bottom is equipped with pressure spring, geosynclinal block is made to have retractility, chamfering
Backplate slot is convenient for geosynclinal block entrance.
Preferably, the ratchet radius is equal to backplate radius, the slide switch adjusts direction and sets along major axes orientation
It sets, the backplate slot position is on the outside of backplate.Spine block and geosynclinal block are simple convex block, are convenient for mass production, backplate slot position is in backplate
Outside, it is easy to process.
Preferably, the slide switch pushing block is equipped with band.Band is used to promote the friction between finger and pushing block, makes
It must slide more simple.
Therefore, the utility model has the following beneficial effects:
(1) to band tape without extruding and friction；
(2) highly reliable；
(3) easy to operate, strong applicability.
