Abstract
The utility model discloses a novel curtain heading brake system, which comprises a heading main body, wherein a core shaft extends on the middle portion of the heading main body, a metal shaft sleeve is sleeved outside the core shaft, a torsion spring is sleeved outside the metal shaft sleeve, a driving component is movably sleeved outside the torsion spring for locking and unlocking the torsion spring, the novel curtain heading brake system has reasonable structure, excellent core shaft abrasion resistance, smooth and stable operation, convenient use and long service life, and is a brake system which is widely used in curtain heading.
Description
Technical field
The utility model relates to a kind of curtain system head, particularly a kind of novel curtain system brake system.
Background technology
At present, common on the market is applied to the system head on the curtain because inner brake system structure design is unreasonable, when people spur bead by the upper and lower motion of curtain, cause the suffered frictional force of mandrel big, extremely require great effort during use, the mandrel easy deformation is damaged simultaneously, and application life is short, at above-mentioned shortcoming, be necessary to make improvements.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, the mandrel abrasion resistance is good, the operation is smooth and easy, steady, a curtain system brake system of long service life.
The technical scheme that its technical problem that solves the utility model adopts is:
A novel curtain system brake system comprises the system head main body, and mandrel is extended at described system head main body middle part, and described mandrel is set with metal axle sleeve outward, is set with torsion spring outside metal axle sleeve, has the actuator movable set outside torsion spring torsion spring to be locked and release.
The beneficial effects of the utility model are: in the use, with pulling moving bead, thereby being moved, actuator realizes the upper and lower folding and unfolding of curtain on mandrel, because mandrel of the present utility model is set with plating outward and presses against the surface-treated metal axle sleeve firmly, reduced the suffered frictional force of mandrel, improve the abrasion resistance and the application life of mandrel, also made bead to spur smoothly simultaneously, and made the roller shutter operation very steady.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the utility model is applied to the structural representation on the curtain system head;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a novel curtain system brake system comprises system head main body 1, mandrel 2 is extended at described system head main body 1 middle part, be set with metal axle sleeve 3 outside the described mandrel 2, outside metal axle sleeve 3, be set with torsion spring 4, have actuator 5 movable sets outside torsion spring 4, torsion spring 4 to be locked and releases.
In the use, with pulling moving bead 6, thereby being moved, actuator 5 realizes the upper and lower folding and unfolding of curtain on mandrel 2, press against surface-treated metal axle sleeve 3 firmly owing to be set with plating outside the mandrel 2 of the present utility model, reduced the suffered frictional force of mandrel 2, improve the abrasion resistance and the application life of mandrel 2, also made bead to spur smoothly simultaneously, and made the roller shutter operation very steady.
The utility model is rational in infrastructure, the mandrel abrasion resistance is good, smooth and easy, steady, the easy to use and long service life of operation, is a kind of brake system that is widely used on the curtain system head.
