Title:
SELF-LOCKING MECHANISM FOR GEAR TRANSMISSION DEVICE, GEAR TRANSMISSION DEVICE, ACTUATOR AND LIFTING PLATFORM
Document Type and Number:
WIPO Patent Application WO/2023/006023
Kind Code:
A1
Abstract:
Disclosed in the present invention are a self-locking mechanism for a gear transmission device, a gear transmission device, an actuator and a lifting platform, which relate to the technical field of lifting tables. The self-locking mechanism comprises a housing, a self-locking gear and a braking member, wherein the self-locking gear meshes with the gear transmission device, the braking member is connected between the housing and the self-locking gear, the braking member releases the self-locking gear when the self-locking gear is driven forwards by the gear transmission device, and the braking member applies braking to the self-locking gear when the self-locking gear is driven backwards by the gear transmission device. The gear transmission device on a transmission chain is self-locked by means of the self-locking gear that is not located on the transmission chain, such that a gear transmission device is prevented from becoming hot due to direct friction between the braking member and the gear transmission device, and the service life of the gear transmission device is prolonged.
