Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a dc voltage-stabilized power supply with safeguard function, including shell 1 and the button 2 that is located shell 1 top, it is concrete, button 2 is shift knob 2 on the power among the prior art, spout 3 near button 2 is seted up at the top of shell 1, the inside sliding connection of spout 3 has slider 4, slider 4's top fixedly connected with is the apron 5 of U-shaped, one side that button 2 was kept away from to slider 4 is through

extrusion spring

6 and 3 elastic connection of spout, the cross-section of spout 3 is the shape of falling T, slider 4's cross-section is the shape of falling T.

The scheme has the following working processes:

when needing to start DC regulated power supply, stimulate apron 5 earlier, apron 5 drives slider 4 and slides in spout 3 for apron 5 leaves button 2 directly over, then presses button 2 on shell 1, make the power start, loosen apron 5 after the power start, apron 5 gets back to button 2 top through extrusion spring 6, later when needing to close the power, repeat above-mentioned step and break away from the top of button 2 with apron 5, press button 2 again, close the power.

According to the working process, the following steps are known:

make in the use, the button 2 that the power was started and was closed can be protected by apron 5 for the power can not receive external factors's interference and close when leading to using, the condition that the machine used appears influencing.

Further, the surface of shell 1 is equipped with protection mechanism 7, and protection mechanism 7 locates the protective housing 701 on shell 1 surface including the cover, the inside bottom of protective housing 701 and the equal fixedly connected with telescopic link 702 of protective housing 701 inboard, and the surface cover of telescopic link 702 is equipped with buffer spring 703, and is concrete, when making the power receive the impact through buffer spring 703 among the protection mechanism 7, can reduce the impact force to the damage of shell 1, reduces the damage that the power received.

Further, telescopic link 702 includes and holds pole 7201 with protective housing 701 fixed connection, holds pole 7201 and has seted up holding tank 7202 near the one end of shell 1, and the inside sliding connection of holding tank 7202 has dead lever 7203, dead lever 7203 and shell 1 fixed connection, and is concrete, and telescopic link 702 makes buffer spring 703 can not misplace and lead to failing to provide the buffering.

Further, the top of the protective shell 701 is rotatably connected with two connecting plates 704 which are symmetrically distributed, specifically, the connecting plates 704 provide limited protection for the top of the shell 1, and sundries are prevented from entering between the protective shell 701 and the shell 1 to affect buffering.
