Supporting device and desktop ultrasonic diagnostic instrument

Abstract

The invention discloses a supporting device and a desktop ultrasonic diagnostic instrument. The supporting device comprises a lower supporting arm component, a connecting joint, an upper supporting arm component, a locking component and a latch, wherein the connecting joint is connected to the upper supporting arm component and the lower supporting arm component; the locking component comprises a locking rod, a mounting base and an elastomer; a hook part is arranged at the top of the locking rod; the bottom of the locking rod is rotatably connected to the mounting base so that the locking rod can rotate up and down relative to the mounting base; the elastomer is firmly pressed between the bases of the mounting base and the locking rod; the mounting base is fixed with the lower supporting arm component; and the latch is arranged on the upper supporting arm component. The locking rod is permitted to rotate up and down only, and the restoring force of the elastomer acts on the bottom of the locking rod to form eccentric force, so that the locking rod is kept under a locking state in the vertical direction to achieve self-locking; and the device disclosed by the invention is simple in structure and convenient in maintenance, and is capable of achieving simultaneously locking on both longitudinal rotation and transverse rotation.

Description

technical field [0001] The application relates to a desktop ultrasonic diagnostic instrument and its supporting device. Background technique [0002] When medical personnel use a medical instrument with a display device (display) (taking a desktop ultrasonic diagnostic instrument as an example), based on the need for convenient movement, it is required that the display device can be locked during the movement process to limit the freedom of up and down, left and right The movement of the display device makes the display device in a relatively static state relative to the whole machine, thus requiring the support device of the display device to have the function of locking up and down pitching and left and right rotation. [0003] There are mainly three types of existing support devices with locking functions: one is through a combination device of a link mechanism and a hidden spring latch mechanism in the support device. When the lock bar is in a lockable state, the two swi...

AI Technical Summary

Problems solved by technology

[0004] For the first type of supporting device, its structure is complex, and once the structure fails, it will be more difficult to maintain, and it can only lock the function of water rotation left and right

For the second type of support device, it is easy to pinch the operator's fingers during the locking process, and the unlocking lever affects the appearance of the product

For the third type of support device, the probability of one-time accurate buckle in place during the locking process is very low, and the user operation is inconvenient
