Electric control caster with compound worm gear for transmission

Abstract

The invention provides an electric control caster with a compound worm gear for transmission. The electric control caster comprises a caster assembly, a body supporting system and a transmission control system. The transmission control system is installed in the body supporting system. The caster assembly penetrates through the body supporting system and is connected with the transmission controlsystem. The body supporting system comprises a supporting sleeve installed on the support, a bearing assembly installed at the lower end of the supporting sleeve, a positioning rotating plate and a wiring harness slide ring. One end of the wiring harness slide ring is electrically connected with a motor power supply and the control system. The current input is controlled by the control system so that the forward and backward rotation of the motor can be controlled; the braking, straight going and universal functions are realized through internal structures; the working states of the caster canbe rapidly switched; the various handled complicated conditions in use are comprehensively considered, the structure is compact, operation is simple, and the working states of the casters can be controlled by means of an electric control panel; the traditional manual operation complexity is effectively avoided, and an effective solution is provided for the intellectualization in the medical fieldand other fields.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a caster assembly arranged at the bottom of products such as nursing beds. Background technique [0002] When traditional casters are in use, the working state of the casters is selected through human control. Usually, the operator will use his hands or feet to operate the designated pressure rod and other force-bearing devices. During use, it is difficult for the operator to The control strength and usage specifications will accelerate the wear of internal parts, and may even directly lead to the scrapping of parts or products due to improper operation or excessive force. Human-mechanical operation will also bring a lot of inconvenience to the operator. In the face of complex working conditions, this kind of human-mechanical operation is more time-consuming and cannot meet the needs of a fast-response working environment. Nowadays, medical equipment has deve...

[0002] When traditional casters are in use, the working state of the casters is selected through human control. Usually, the operator will use his hands or feet to operate the designated pressure rod and other force-bearing devices. During use, it is difficult for the operator to Controlling strength and usage specifications will accelerate the wear of internal parts, and may even directly lead to the scrapping of parts or products due to improper operation or excessive force

Human-mechanical operation will also bring a lot of inconvenience to the operator. In the face of complex working conditions, this kind of human-mechanical operation is more time-consuming and cannot meet the needs of a fast-response working environment.
