Referring to fig. 1, the head cover in the first embodiment of the present invention includes a head cover body 10, and a plurality of supporting structures are disposed on the outer side surface of the head cover body 10. In the embodiment, in order to make the matching stress of the roller pipe 60 and the head making cover body 10 uniform, the number of the supporting structures is two or more, the supporting structures are distributed at intervals along the circumferential direction of the head making cover body 10, and further, the supporting structures are spaced at equal intervals, so that the head making head can uniformly transmit the torque to the roller pipe 60 through the supporting structures.

The head making cover in the present application can be applied not only to the head making but also to the tail making to improve the interchangeability of the components of the roller shutter.

Referring to fig. 2 to 3, in the embodiment, the supporting structure includes a supporting rib 20 and a deformable supporting piece 30, the supporting piece 30 is fixed on the supporting rib 20, an abutting portion 40 is provided on an outer side surface of the supporting piece 30, and an avoiding space 31 is provided between an inner side surface of the supporting piece 30 and an outer side surface of the head making cover body 10. The abutting part 40 can abut against the inner side of the roller pipe 60, and during assembly, the supporting sheet 30 deforms and is pressed to the avoiding space 31, so that abrasion caused by hard contact between the abutting part 40 and the roller pipe 60 is avoided; after assembly, the support piece 30 tends to return to its original shape, so that the abutting portion 40 can be tightly pressed against the inner side of the roll pipe 60 to ensure interference fit of the head cover with the roll pipe 60. The abutting portion 40 protrudes from the outer side surface of the support piece 30, and a projection of the abutting portion 40 on the inner side surface of the support piece 30 faces the escape space 31. Specifically, the outer side surface of the supporting sheet 30 includes a first composition surface 51 and a second composition surface 52, the inner side surface of the supporting sheet 30 includes a first inner composition surface and a second inner composition surface, the supporting rib 20 is connected with the first inner composition surface of the supporting sheet 30, and the avoiding space 31 is located between the second inner composition surface and the outer side of the head making cover body 10. The first composition surface 51 is opposite to the support rib 20, that is, the projection of the first composition surface 51 on the plane of the inner side surface of the support sheet 30 is superposed with the first inner composition surface; similarly, the second composition surface 52 is opposite to the avoidance space 31, that is, a projection of the second composition surface 52 on a plane on which the inner side surface of the support sheet 30 is located coincides with the second inner composition surface. Since the abutting portion 40 is located on the second component surface 52, when the roller pipe 60 is assembled and abutted, the abutting portion 40 can push the support piece 30 to press the escape space 31, and friction between the abutting portion 40 and the roller pipe 60 is reduced.

In order to facilitate the insertion and fixation of the head cover into the roller tube 60, in the embodiment, the support rib 20 has a long bar shape, and the length direction of the support rib 20 is parallel to the axial direction of the head cover body 10. Accordingly, the support sheet 30 has a rectangular shape, and the length direction of the support sheet 30 is parallel to the length direction of the support rib 20. The abutting portion 40 includes two abutting projections 41, and optionally, the abutting projections 41 are elongated, and the length direction of the abutting projections 41 is parallel to the axial direction of the head making cover body 10. In the embodiment, the support rib 20 is connected to the central axis of the support sheet 30, and the two abutting protrusions 41 are symmetrically distributed about the support rib 20, that is, the distance between each abutting protrusion 41 and the support rib 20 is equal, so as to ensure the stress balance of a single support structure.

Further, a head making base is arranged at the bottom of the head making body 10, and an extension part can be arranged at the bottom end of the center shaft of the support sheet 30 to be connected with the head making base so as to strengthen the connection between the support sheet 30 and the head making body 10. The inner side of the central axis of the supporting sheet 30 is connected with the supporting rib 20, the bottom end of the central axis of the supporting sheet 30 is connected with the head making cover base, and the left end and the right end of the supporting sheet 30 are both free ends, so that the supporting sheet is easier to be pressed into an avoiding space. Accordingly, the two abutting protrusions 41 are respectively located at two sides of the extending portion, that is, the two abutting protrusions 41 are respectively located at the outer sides of the left and right free ends of the supporting piece, that is, the second composition surface 52.

In some embodiments, to simplify the structure, the support piece 30 is integrally formed with the support rib 20, and further, the support piece 30 is integrally formed with the abutting portion 40.

In some embodiments, to reduce wear between the abutment 40 and the roller tube 60, the abutment 40 may be deformable, with the abutment 40 being a resilient member. Optionally, the outer side surface of the abutting part 40 and the surface of the abutting part 40 abutting against the roller pipe 60 are arc-shaped surfaces, so that the contact area is reduced, and the installation is more convenient.

The utility model discloses system head in the embodiment of second aspect, it includes foretell system head lid.

The utility model discloses roll up curtain in third aspect embodiment, it includes drive arrangement, reelpipe 60, the curtain body, system tail and foretell system head, and the curtain body is convoluteed on reelpipe 60, and system head is connected respectively at the both ends of reelpipe 60 with the system tail, specifically, and system head inserts the tip of reelpipe 60, and the system tail is the same reason. The driving device is connected with the head, and the driving device can be a motor or a ball pulling device.

Referring to fig. 4, in the embodiment, the number of the support structures of the head making cover is more than two, and the support structures are circumferentially arranged at intervals. To avoid relative rotation between the headpiece and the roller tube 60. More than two grooves 61 are arranged in the rolling pipe 60, and each supporting structure is clamped and fixed in one groove 61. The support structure snaps into the groove 61 and the abutment 40 abuts against the inner bottom surface of the groove 61.

Further, in order to avoid radial relative displacement between the support structure and the roller pipe 60, a limiting protrusion 62 is arranged on the inner bottom surface of the groove 61 of the roller pipe 60, and the limiting protrusion 62 abuts against the outer side surface of the support sheet 30. In the embodiment, the two abutting protrusions 41 on the support sheet 30 form a recess on the outer side surface of the support sheet 30, when the head is assembled with the roller pipe 60, the support sheet 30 deforms to the avoiding space 31, and the distance between the outer side of the support sheet 30 and the inner bottom surface of the groove 61 is reduced until the limiting protrusion 62 abuts against the outer side surface of the support sheet 30. At this time, since the stopper projection 62 abuts against the outer side surface of the support piece 30, the support piece 30 cannot approach the inner bottom surface of the groove 61 in the radial direction any more, and the relative position of the support structure and the groove 61 is fixed, so that the head cover and the roller pipe 60 do not move relatively.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited thereto, and various changes and modifications may be made without departing from the spirit of the invention.
