Description

Technical Field

[0001] The utility model belongs to the technical field of door and window accessories, and in particular relates to a transmission structure and a door and window. Background Art

[0002] Existing doors and windows often have hidden transmission rods inside. These transmission rods are used to connect various hardware parts. The function of the transmission rods is to transmit motion, so that the scattered hardware becomes a complete hardware system. The transmission rods need to be cut and punched after calculation before installation. The cutting accuracy of the transmission rods directly affects the transmission accuracy. During the cutting process of existing transmission rods, the length of the transmission rods is easily inaccurate due to equipment or human factors, resulting in defective products. This also causes a distance error between the transmission rods and the hardware on the doors and windows, making it impossible to install. For this reason, re-cutting is required, which greatly increases production costs. Utility Model Content
