Embodiment 1

[0034] Such as Figure 1 to Figure 8 As shown, the lifting screen 001 fine-tunes the wire reel assembly, including the screen fixing seat and the self-locking wire reel 004, and the self-locking wire reel 004 includes the wire reel base 1, the wire reel 2 and the driving part, and the screen is fixed The seat is installed on the lifting screen 001, the wire reel base 1 is fixed on the screen fixing seat, the wire reel 2 is fixedly connected with the driving part, and the driving part drives the wire reel 2 to move axially relative to the wire reel base 1 and / or Or rotate, there is a self-locking mechanism between the cord reel base 1 and the cord reel 2, the cord reel 2 moves axially relative to the cord reel base 1 to self-lock or unlock, and the screen fixing seat is provided with a width adjustable Adjusted slot 9, the lower edge of the lifting screen 001 is inserted in the slot 9.

[0035]The self-locking wire reel 004 in this embodiment is installed on both sides of the ...

Embodiment 2

[0059] The difference between this embodiment and the first embodiment is that the self-locking mechanism is closer to the lifting screen 001 than the driving part, and in the winding mode, the driving part pulls the winding wheel 2 to move outward and unlock.

[0060] At this time, the compression spring or shrapnel used as the elastic reset member 4 should be arranged between the cord reel 2 and the cord reel base 1 .

Abstract

The invention discloses a lifting screen fine adjustment winder assembly and belongs to the technical field of lifting devices. The lifting screen fine adjustment winder assembly comprises a screen fixing seat, a winder base, a winding wheel and a driving part, wherein the screen fixing seat is mounted on a lifting screen, the winder base is fixed on the screen fixing seat, the winding wheel is fixedly connected with the driving part, the driving part drives the winding wheel to axially move and/or rotate relative to the winder base, a self-locking mechanism is arranged between the winder base and the winding wheel, the winding wheel axially moves relative to the winder base to achieve self-locking or unlocking, a width-adjustable inserting groove is formed in the screen fixing base, a lower edge of the lifting screen is inserted into the inserting groove. By adopting the fine-tuning winder assembly for the lifting screen, pulling belts are subjected to small-range retraction and extension and relaxation adjustment, so lengths of the pulling belts at the two ends are basically consistent, the balance of the lifting screen is ensured, the normal mounting distance and stroke of the lifting screens with different weights are ensured, the fine-tuning winder assembly is locked immediately after adjustment is completed, and stability of the lifting screen is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of lifting devices, in particular to a fine-tuning wire reel assembly for a lifting screen. 【Background technique】 [0002] The screen desk is a whole composed of a screen and a desk. The combination of the screen desk is more and more used in the office space. The adjustable function of the screen puts forward higher and higher requirements, so there is a height-adjustable lifting screen, which drives the screen to rise and fall by pulling the belt. Pull the two pull belts at the same time through the coiler to make the screen rise and fall stably, but in actual installation, there will be situations where the two pull belts are different in length due to installation errors, or the pull belts are loaded with different types of screens. When the length changes due to elastic deformation, resulting in changes in the installation distance and stroke, or special shift installation, etc., at least one pull b...
