Abstract
The utility model relates to a roll up the curtain, self -locking spring system head for the curtain. Self -locking spring system head including the shell, is provided with the backstop overcoat on the shell, the lower extreme of backstop overcoat is connected with fixed power spring, the inside self -lock device that is provided with of backstop overcoat. For prior art, from locking -type spring system head, it mainly adopts spring leaf (having another name called fixed power spring) to receive and release the curtain, and it is even to reach drop -down strength, and the curtain is not fragile, but also can select the pulling force of spring according to the quality of cloth, be furnished with self -lock device in the system head, can go up and down to stop (can stopping in any place), convenient to use in any position, be located outside of tubes portion because of making the head, backstop overcoat and union coupling, therefore simple to operate can dock with the pipe of any specification.
Description
Technical field
The utility model relates to a kind of roller shutter, curtain self-locking spring head.
Background technology
The existing spring curtain in market is that spring is placed in pipe mostly, and the rotation spring elastic force along with pipe becomes large gradually, and time namely curtain is drop-down, pulling force can be increasing, can cause damage like this because accessory can not bear too large pulling force; And this system needs to coordinate pipe assembling, more replace tubes specification should not use.
Utility model content
The technical problems to be solved in the utility model is: the rotation spring in existing spring curtain is contained in pipe, the spring tension that when curtain is drop-down, needs overcome is increasing, the power causing accessory to bear is too large, easy damage, the pipe that spring curtain coordinates is changed cumbersome, for solving the problem, provide a kind of self-locking spring head.
The purpose of this utility model realizes in the following manner:
Self-locking spring head, comprises shell, shell is provided with backstop overcoat, and the lower end of backstop overcoat is connected with fixed force spring, and backstop jacket internal is provided with self-locking device.
Backstop overcoat lower end is arranged in the enclosure.
Self-locking device is backstop.
Self-locking device is positioned at the lower end of backstop overcoat.
Backstop is cylinder type, the outer wall of backstop is provided with continuous print deep-slotted chip breaker, deep-slotted chip breaker is provided with at least one low spot, is provided with ball in deep-slotted chip breaker, ball slides into nearest deep-slotted chip breaker low spot under the effect not having external force, puts the chute be provided with ball engagement outside backstop.
Shell is provided with pillar, and on pillar, cover has torsion spring, and backstop is sleeved on pillar, and backstop lower end has groove, and the snatch of torsion spring is arranged in the groove of backstop lower end.
Shell is provided with connector, and connector is connected with the pillar on shell by screw.
Relative to prior art, self-locking spring head, it mainly adopts spring leaf (also known as fixed force spring) to carry out folding and unfolding curtain, and reach drop-down strength even, curtain is not fragile, but also can according to the pulling force of the quality choice spring of cloth; Be furnished with self-locking device in head processed, (can be parked in Anywhere) can be stopped in the lifting of any position, easy to use; Because head processed is positioned at pipe outside, backstop overcoat is connected with pipe, therefore easy for installation, can dock with the pipe of any specification.
