Adjustable support of roller shutter, roller shutter and roller shutter

Technical Field

The utility model belongs to the technical field of roller blinds, and particularly relates to an adjustable bracket of a roller blind. The utility model also relates to a rolling and unwinding assembly with the rolling and unwinding adjustable bracket and a rolling and unwinding device.

Background

The rolling curtain is one of window decoration products, and is a curtain product which is formed by rolling curtain cloth on a scroll and driving the scroll to rotate by adopting a pull rope or a motor and the like so as to enable the curtain cloth to ascend or descend. The roller blind is usually mounted by mounting both ends of the roller shaft on a bracket or by abutting both ends of the roller shaft against a window frame. A single small bracket for mounting a roller shaft is commonly referred to in the roller blind art as a mounting bracket or bracket.

In the prior art, two supporting yards are respectively arranged to support the mounting modes of the two ends of the scroll, namely, the supporting yards are fixedly connected to the window frame, and the scroll is erected on the supporting yards. However, in the actual installation process, the supporting codes are respectively arranged, and the actual shape and design of the window frame are possibly provided with a certain error, so that the problem that the installation surface is fluctuated is possibly caused, the installation skill of a worker is tested when the rolling shutter scroll is perfectly installed, the problem that the connecting lines between the two supporting codes are not parallel easily occurs, and the rolling shutter scroll erected on the supporting codes is inclined, so that the normal use and the attractive degree of the rolling shutter are influenced. In the prior art, the connection position of the supply scroll on the bracket is fixed and cannot be adjusted.

Disclosure of Invention

In order to solve the above technical problems, it is necessary to provide an adjustable bracket for a roller shutter, which can adjust the height of the end of the roller.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model provides an adjustable support sign indicating number of rolling up curtain, includes the support that is equipped with the spout and supplies spool end connection's slider, the slider can follow the spout is in slide on the support, still include be used for locking the slider with relative position between the support slider locking piece.

When the adjustable bracket for the roller shutter is used, the whole adjustable bracket can be fixed at a proper position, then the position of the sliding block, namely the roller shaft mounting point, is adjusted by sliding the sliding block in the sliding groove, and the sliding block is adjusted to a proper position and then is locked by the sliding block locking piece. The sliding block can slide in the sliding groove, so that the reel erection position can be adjusted in the travel range of the sliding block; the spool position can be fixed due to the slider lock locking the relative position between the slider and the slider bracket. Even in the case of uneven mounting surface, the reel can be leveled for use.

Preferably, the sliding block locking piece comprises a positioning screw rod abutted to the bottom of the sliding block, a screw hole for the positioning screw rod to pass through is formed in the bottom of the support from bottom to top, and the positioning screw rod can be screwed in along the screw hole to jack up the sliding block or screwed out along the screw hole to put the sliding block downwards. In the structure, the positioning screw rod is matched with the screw hole to adjust the position of the sliding block relative to the sliding block support in a controlled manner. The limiting screw is abutted to the bottom of the sliding block, and the sliding block is only subjected to gravity, so that the position of the sliding block can be locked without a guide mechanism.

Preferably, the sliding block is provided with a bayonet for the blocking of the blocking piece, and the blocking piece is blocked into the bayonet to connect the positioning screw with the sliding block. In the structure, the stop piece is connected to the positioning screw and is clamped with the bayonet, so that the positioning screw can lift up and adjust down to drive the sliding block to move automatically without separate adjustment.

Due to the through holes, the sliding block can be used for supporting the connecting position of the two roller blinds and can be adjusted up and down, and the sliding block can be used as an intermediate bracket under the condition of multi-roller shaft communication.

Preferably, the support further comprises a slide support detachably connected to the through hole, i.e. the slide support forms a part of the side wall of the through hole, and the sliding groove is arranged on the slide support. In the structure, the sliding block support is detachable, and when the matching of the sliding groove and the sliding block is problematic, the sliding block support can be detached for checking and repairing.

Preferably, the sliding groove comprises a left sliding groove arranged on the left side wall of the through hole and a right sliding groove arranged on the right side wall of the through hole, and the sliding block is provided with a left bulge matched with the left sliding groove and a right bulge matched with the right sliding groove.

Preferably, a bearing is arranged on the sliding block. Because the sliding block is used for connecting the rolling shutter scroll, the scroll is rotated to lower or lift the curtain body arranged on the rolling shutter scroll, and the bearing is connected with the rolling shutter scroll, so that the rotation of the scroll is more silky and durable.

A winding and unwinding assembly comprises a winding shaft, one or both ends of which are connected to a shutter adjustable bracket as described above. Because the adjustable support code of the roller shutter is included, the rolling and unreeling assembly has all the beneficial technical effects brought by the adjustable support code of the roller shutter, and the detailed description is omitted.

A rolling curtain comprises a curtain body and the rolling and unreeling assembly, wherein one end of the curtain body is connected to a reel, and the curtain body is driven to roll or unreel through rotation of the reel. Because the rolling and unwinding assembly is included, the rolling curtain has all the beneficial technical effects brought by the rolling and unwinding assembly, and the rolling and unwinding assembly is not described in detail herein.
