Specific embodiment
Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality
It applies example and attached drawing is cooperated to be explained in detail.
The utility model provides a kind of function handcart emergency unlocking device, the urgent solution referring to FIG. 1 to FIG. 4,
Locking device includes button assembly 100, unlock assembly 200 and latching electromagnet 300；
The function handcart includes chassis vehicle 540, the cabinet being set on chassis vehicle 540 510 and chassis turnover panel 530.Institute
Emergency start component of the button assembly 100 as emergency unlocking device is stated, the operating force of operator's application is directly received.Specifically
, the button assembly 100 includes button set 110, button 120 and spring 130, and the button set 110 is sheathed on outside button 120,
The button 120 includes button head and button bar, and button bar one end is fixed in button head, and the spring 130 is sheathed on outside button bar；
In actual use, the button assembly 100 is fixed on the panel of function handcart 500 by button set 110,120 court of button
To the outside of panel, button bar can be contacted with unlock assembly 200, and the spring 130 is for providing restoring force, after button head is depressed
With moving inward, spring 130 is shunk button bar therewith, and after the external force of application disappears, spring 130 restores elastic deformation, button
Assembly 100 returns to original state.Blocking due to button 120 in this configuration, 500 cabinet of function handcart, 510 panel
On without gaps visible, improve the aesthetics of whole device.
Transmission mechanism of the unlock assembly 200 as the present apparatus, mainly transmits the power that button assembly 100 applies.Tool
Body, the unlock assembly 200 includes guide part 210 and unlock piece 220, and the unlock piece 220 is installed on guide part 210,
Unlock piece 220 can be slided along guide part 210, and the unlock piece 220 is located on the path of button bar movement；The guide part 210 is used
In the installation unlock piece 220, and limits unlock piece 220 and moved along preset path, it is described in unlock assembly 200
Unlock piece 220 is located on the path of button bar movement, it can be ensured that power can be transferred to unlock piece 220 by button bar, and by unlock piece
220 continue transmitting downwards.
