Abstract
The invention provides a slowly-retracted steel tap, wherein a pressure spring piece and a rectifying screw are arranged on the steel tap; and the pressure spring piece is pressed on a steel rule, and the rectifying screw can adjust the pressure of the pressure spring piece to the steel rule, so that the retraction speed of the steel rule can be controlled. Due to a slowly-retracted mechanism, the problem that users are injured due to the quick retraction of the steel rule can be avoided.
Description
Affiliated technical field:
The present invention relates to a kind of steel tape, especially can pull out at steel tape and measure the rear inoffensive steel tape that bounces back slowly of slowly retracting.
Background technology:
At present, known steel tape has a locking key when pulling out measurement, this locking key is up pushed away just making steel ruler motionless.After measuring, this key is pushed away toward next, steel ruler just enters in the box of tape measure fast; Because the speed that is involved in is too fast, usually hurts sb.'s feelings.
Summary of the invention:
Return the too fast deficiency of chi speed in order to overcome existing steel tape, the invention provides a kind of steel tape, this steel tape does not only affect the use of steel tape, and can be after steel tape is measured, and steel ruler slowly retracts in the box, prevents that invar chi retraction is too fast and hurts sb.'s feelings.
The technical solution adopted for the present invention to solve the technical problems is:
In the outlet appropriate location of steel tape, a pressure spring sheet is installed is pressed on the steel ruler, there is one to adjust spiral and adjust this spring leaf and be pressed in pressure on the steel ruler above the pressure spring sheet, can adjust as required like this speed of steel ruler retraction.
The invention has the beneficial effects as follows:
The chi speed of returning that prevents the invar tape measure makes the people injured too soon.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples:
Figure one is structural representation of the present invention
Among the figure, 1 steel tape box, 2 steel rulers, 3 times chi springs, 4 times chi spring cases, 5 locking keys, 6 pressure spring sheets, 7 adjust spirals.
Embodiment:
In the drawings, appropriate location above the outlet of steel tape box 1, a pressure spring sheet 6 is installed, this pressure spring sheet 6 just is pressed in above the steel ruler 2, on pressure spring sheet 6, an adjustment spiral 7 is installed is again contacted with pressure spring sheet 6, this spiral can be adjusted the pressure of 6 pairs of steel rulers 2 of pressure spring sheet, thereby adjusts the speed of steel ruler 2 rollbacks of steel tape;
When measuring, steel ruler 2 is pulled out, at this moment return chi spring 3 returning chi spring case 4 interior storage power, promote locking key 5, steel ruler 2 is stopped, and measures; After measuring, locking key 5 is pushed away toward next, steel ruler 2 is returned the stored quick rollback of energy of chi spring 3; Owing to increased pressure spring sheet 6 and adjusted spiral 7, the energy of chi spring 3 has slowly been discharged, thereby reach the purpose of the steel ruler 2 that bounces back slowly.
Claims (1)
1. the steel tape that bounces back slowly is equipped with the pressure spring sheet at the steel tape box and is pressed on the steel ruler with the adjustment spiral, and it is characterized in that: adjust spiral and contact with the top of pressure spring sheet, the following and steel ruler of pressure spring sheet contacts.
