Problems solved by technology

[0003] Existing honeycomb curtains use drawstrings to control the rise and fall of the curtain body, and adjust the shading height and lighting level. It requires a large force to pull the drawstrings, and the operation is troublesome. The exposed drawstrings may cause accidents such as entanglement with the human body, especially It poses a safety hazard to parents and children, and also affects the aesthetics; a few honeycomb blinds that use gravity balance, their internal components and the direction of their force are easy to deflect, resulting in poor performance and stability of the blinds, affecting their service life, and causing users The user experience is not good

Abstract

The invention discloses a double-layer constant-force spring type pull-rope-free honeycomb curtain. The double-layer constant-force spring type pull-rope-free honeycomb curtain comprises a curtain body and an installation frame arranged on the upper portion of the curtain body, an installation groove is formed in the installation frame, a first spring assembly and a second spring assembly are arranged in the installation groove, and the first spring assembly is located on the upper portion of the second spring assembly. Compared with a single constant-force spring, the double-layer constant-force springs are adopted in the honeycomb curtain, so that the designable length range of the honeycomb curtain is larger, the situation that the honeycomb curtain is not suitable for an application scene due to length limitation is avoided, and the application range of the honeycomb curtain is greatly widened.

Description

technical field [0001] The invention relates to the technical field of honeycomb curtains, in particular to a double-layer constant force spring-type cordless honeycomb curtain. Background technique [0002] The unique honeycomb design of the honeycomb curtain allows the air to be stored in the hollow layer to keep the indoor temperature constant and save air-conditioning electricity costs. Its anti-ultraviolet and heat insulation functions effectively protect household items, anti-static treatment, and easy washing. The drawstring is hidden in the hollow layer and has a perfect appearance, making it easier and more practical for customers to use than traditional devices. [0003] Existing honeycomb curtains use drawstrings to control the rise and fall of the curtain body, and adjust the shading height and lighting level. It requires a large force to pull the drawstrings, and the operation is troublesome. The exposed drawstrings may cause accidents such as entanglement with...
