Flexible bolt device and medical equipment

Abstract

The invention provides a flexible bolt device. A sliding block can slide along a guide rail, and an elastic pin can slide relative to the sliding block and can be in linkage with the sliding block; the elastic pin is further matched with a pin hole of a second component; a locking mechanism can lock the sliding block at a first position, so that a locking state or a pre-locking state is achieved; and in addition, the locking mechanism can also position the sliding block at a second position, so that the elastic pin is reset. During operation, the sliding block can be pushed to slide to a locking position, and the sliding block pushes the elastic pin to generate a linkage effect; if the elastic pin is aligned with the pin hole, the elastic pin is pushed by the sliding block to be inserted into the pin hole, and the locking state is achieved; and if the elastic pin is not aligned with the pin hole, the elastic pin is blocked, the sliding block generates pre-tightening force on the elastic pin, and the pre-locking state is achieved. Therefore, the flexible bolt device can adjust the relative position of a kinematic pair in the pre-locking state, so that the elastic pin can be smoothly and automatically inserted into the pin hole, and the operation is simplified. The invention further provides medical equipment with the flexible bolt device. The medical equipment has the same beneficial effects.

Description

technical field [0001] The invention belongs to the technical field of latch devices, in particular to a flexible latch device and medical equipment. Background technique [0002] In the prior art, during the transfer of medical devices, the locking of the kinematic joints is generally manually operated by the operator. For example, when the monitor arm of an ultrasound trolley is packaged and transported or moved between departments, the rotating joint of the monitor arm needs to be fixed to prevent unexpected movement of the monitor arm during transport, causing damage to the monitor or causing damage to the human body. harm. [0003] At present, fasteners such as self-locking bolt devices or set screw devices are generally used, and both devices use rigid connections. The latch device needs to turn the latch hole on the moving part to align with the latch before it can be inserted and locked. If it is not aligned, the locking cannot be completed. The set screw needs th...

AI Technical Summary

Problems solved by technology

The latch device needs to turn the latch hole on the moving part to align with the latch before it can be inserted and locked. If it is not aligned, the lock cannot be completed

The set screw needs the flat opening on the moving part to face the position of the set screw, if not aligned, the effective locking force cannot be achieved

[0004] Both of the above two devices need to be aligned to lock, but the latch and the latch hole are inside the shell, and the operator cannot see their relative positions. The operator needs to take into account the state of the moving parts and the locking device, and sometimes needs to repeatedly adjust the movement The location of the parts is inconvenient to operate
