Abstract
The invention relates to a self-locking spring head for roller shutters and curtains. The self-locking spring head comprises a housing. The housing is provided with a non-return device coat; the lower end of the non-return device is connected with a constant force spring; and a self-locking device is disposed in the non-return device coat. Compared with the prior art, a curtain is rolled up and unrolled mainly via a spring leaf (also named as the constant force spring) to achieve even downward-pulling force, so the curtain cannot be easily damaged; spring pulling force can be selected according to cloth quality; the self-locking device is assembled to the head, so the head can elevate and stop in any positions; convenient use can be achieved; and the head is arranged outside a pipe and the non-return device coat is connected with the pipe, so convenient installation can be realized and the head can be abutted against pipes with various specifications.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention 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 object of the invention is to realize 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.

Detailed description of the invention
As shown in figs 1 to 6, self-locking spring head, comprises shell 1, shell 1 is provided with backstop overcoat 4, the lower end of backstop overcoat 4 is connected with fixed force spring 5, and spring leaf 5 is contained on backstop overcoat 4, utilize its elastic force to carry out folding and unfolding curtain, backstop overcoat 4 inside is provided with self-locking device.Backstop overcoat 4 lower end is arranged in shell 1.Self-locking device is backstop 6.Self-locking device is positioned at the lower end of backstop overcoat 4.
Backstop 6 is cylinder type, the outer wall of backstop 6 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, backstop overcoat 4 is provided with the chute with ball engagement.
Shell 1 is provided with pillar, and on pillar, cover has torsion spring 7, and backstop 6 is sleeved on pillar, and backstop 6 lower end has groove, and the snatch of torsion spring 7 is arranged in the groove of backstop 6 lower end, and curtain positioning action is played at this position.
Shell 1 is provided with connector 3, connector 3 is connected with the pillar on shell 1 by screw 8, and backstop overcoat 4 and shell 1 are connected together.
