TECHNICAL FIELD
[0001] The application relates to a joint docking device and particularly relates to a joint docking error compensation device. BACKGROUND
[0002] During a surgery, surgical waste liquid needs to be collected. After the surgery is completed, the equipment (hereinafter referred to as a negative pressure suction device) for collecting the surgical waste liquid needs to be pushed to a dirt room, and the surgical waste liquid in the equipment is discharged. The discharge of the waste liquid needs to be performed by using a device called a liquid discharge station. The specific process is as follows: a medical staff member pushes the negative pressure suction device to the front of the liquid discharge station, pushes the negative pressure suction device to the front of the liquid discharge station, and makes the front of the liquid discharge station and the front of the negative pressure suction device fit. At this time, the liquid discharge station is started, the joint for discharging the waste liquid in the liquid discharge station is pushed out through a lead screw module, and the joint is slowly connected to the joint of the negative pressure suction device during the pushing process. After being connected to the final position, the process is stopped. However, the allowable error of the joint connection process is very small, and the joint cannot be connected if the joint is slightly tilted.
[0003] A similar solution found in the market at present is that the joint is mounted on a fixed mechanism, and then the mechanism is supported by two left and right springs below the mechanism to realize up-and-down floating. The cylinder for pushing the joint passes through the two left and right springs, that is, a total of four springs. The entire mechanism is supported by the two left and right springs. The solution has the defects of large occupied volume and inconvenient operation. SUMMARY
[0004] The application provides a joint docking error compensation device. The device has high integration, the entire error compensation mechanism is integrated, and the device has small occupied volume. The device has wide application range and can be applied to various scenes and multiple industries in need. The device can be used in a left-and-right joint docking scene and can also be used in an up-and-down joint docking scene. After the joint docking is completed, the device can be reset to avoid large deviation in next use due to the failure of resetting. The device can realize accurate joint docking of more than one joint, for example, two or three joints.
[0005] Therefore, the application provides a joint docking error compensation device.

[0013] As an optional technical solution of the present application, the joint module includes two docking mother pipes corresponding to the liquid outlet docking sub-pipes, and a guide rod corresponding to the guide rod positioning sleeve, which are arranged on the compensation plate.
[0014] As an optional technical solution of the present application, a trumpet-shaped opening is provided at the end of the guide rod positioning sleeve, and a guide tip portion is provided at the end of the guide rod.
[0015] By adopting the above technical solution: by setting the guide rod and the guide rod positioning sleeve, when docking, the guide tip gradually enters the guide tip, which can play a directional role and facilitate accurate docking.

[0023] By adopting the above technical solution: when the negative pressure suction device approaches the drainage station, the guide slope can be used to guide it so that the liquid outlet docking mechanism and the drainage docking mechanism can be preliminarily docked. Secondly, the two clamping rocker arms can be unfolded, and due to the action of the torsion shaft, the negative pressure suction device can be clamped.
[0024] The working principle and beneficial effects of this application are: 1.
