Abstract
The utility model discloses a tape with an automatic locking structure and a double-pressing tightening structure. The tape includes a tape box which is provided with a chamber; a tape belt which is winded in the chamber and capable of being pulled out or winded in from an opening of the tape box, wherein a brake block is disposed in the tape box, a straight line portion of the tape belt goes through an interval between the brake block and the internal wall of the tape box, an end of the brake block is pivoted on a first convex shaft of the tape box, a reset spring is sleeved on the first convex shaft, and the reset spring drives the front end of the brake block to cling to the internal wall of the tape box; and a double-pressing tightening structure. The tape provided by the utility model has advantages of being simple in structure, being low in cost, being easy and convenient to operate, being with the automatic locking function and the pressing tightening function, being labor-saving and durable, being capable of cooperating with LED lamps, and being practical.
Description
Technical field
The utility model relates to survey instrument technical field, is specifically related to a kind of have auto lock and two tape measure of pressing tightening structure.
Background technology
Tape measure is as the survey instrument of engineering staff's indispensability, and the technical performance index that simultaneously possess is to portably use conveniently, and folding and unfolding quick and safe is cheap, firm and durable.The steel ruler band of existing steel tape is manually to pull out in use, and automatic retraction is used inconvenience, and security performance is poor, and the too fast easy wound finger of retraction speed is not bery applicable in many places.In addition for the frequent occasion that needs to change measurement length, frequent manual withdrawal certainly will affect result of use, and press the button the also extremely difficult control of length that steel ruler band stretches out housing from reel, at dark place, with also needing to be equipped with in addition lighting device, assist in addition.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is to provide a kind of have auto lock and two tape measure of pressing tightening structure.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of have auto lock and two tape measures of pressing tightening structure, comprise the chi box that is provided with cavity, be curled in described cavity and the chi band that can extract out or involve in from the opening of chi box, in described chi box, be equipped with brake block, described chi band straight line portion is through the gap location between brake block and chi box inwall, one end of described brake block is articulated on the first protruding axle of described chi box, a sheathed back-moving spring on described the first protruding axle, described back-moving spring drives described brake block front end to be close on chi box inwall,
Two tightening structures of pressing comprise thumb finger pressing section, forefinger finger pressing section, described thumb finger pressing section and forefinger finger pressing section are located at respectively on described chi box and are positioned on the sidewall of opening both sides, described brake block sidewall is provided with a projection, the head of described forefinger finger pressing section contacts with projection, thereby press forefinger finger pressing section, drives brake block to move upward away from described chi box inwall; Middle part, described thumb finger pressing section is articulated on the second protruding axle of chi box, and its head props up the lower surface of described brake block, presses rear end, thumb finger pressing section, thereby drives brake block to move upward away from chi box inwall; On described chi box, be positioned on the sidewall that chi band stretches out direction and be also provided with LED lamp.
On described chi box lateral wall, be also useful on the shift knob of controlling described LED lamp.
(3) beneficial effect
The utility model is compared to prior art, has following beneficial effect: it is simple in structure, with low cost, operates easy and conveniently, and possesses auto lock and rolling pressing function, and laborsaving durable, cooperated with LED lamp is used, and has practicality.
Accompanying drawing explanation
Fig. 1 is have auto lock and two cut-away view of pressing the tape measure of tightening structure of the present utility model.
Fig. 2 is the structural drawing with the pressing structure of auto lock and two tape measures of pressing tightening structure of the present utility model.
Embodiment
