Adjustable direct-current stabilized power supply

Abstract

The invention provides an adjustable direct-current stabilized power supply which comprises a box body, a placement groove is formed in the inner wall of the bottom of the box body, a stabilized power supply body is placed in the center of the placement groove, and a protection assembly for flexibly sealing the stabilized power supply body is movably installed at the top end of the box body. The protection assembly comprises a connecting assembly flexibly connected with the box body and an auxiliary assembly for auxiliary connection, and the connecting assembly and the auxiliary assembly are movably installed at the top end of the box body. The connecting assembly comprises a box cover, rotating shafts, rotating plates, connecting plates and inserting plates, the box cover is placed at the top end of the box body, the rotating shafts are rotationally installed in the centers of the tails of the left and right ends of the box cover, the rotating plates are symmetrically and fixedly installed on the outer surfaces of one sides of the left and right rotating shafts in a surrounding mode, and the connecting plates are fixedly installed at the top ends of the left and right side walls of the box body. According to the adjustable direct-current stabilized power supply, the power supply is protected and closed without adopting bolts, so that the adjustable direct-current stabilized power supply can be conveniently taken, and the adjustable direct-current stabilized power supply is relatively simple and convenient and saves manpower.

Problems solved by technology

[0002] When the existing regulated power supply is in use, the dust contained in the air will enter the inside of the regulated power supply from the heat dissipation holes on the regulated power supply, and accumulate in the inside of the regulated power supply for a long time, which will damage the regulated power supply. The operation of the power supply is affected and it is troublesome to clean it. At the same time, the regulated power supply itself can only dissipate heat through the cooling holes, resulting in slow heat dissipation during work, and the remaining heat remains inside the regulated power supply. Long-term use will cause circuit damage. Aging shortens the service life of the regulated power supply, and the regulated power supply lacks the necessary protective mechanism, and it will cause damage to the regulated power supply after falling vertically from a high place

[0003] In view of the above-mentioned problems, regarding the technical problems such as the inconvenient heat dissipation of the existing regulated power supply, after a large number of searches, a small adjustable DC regulated power supply with a patent number of CN202120803091.8 was found, including the regulated power supply body, The rear end of the stabilized power supply body is provided with a cooling device, the cooling device includes a connecting plate, cooling fan and installation strips, and the first protection mechanism is arranged on both sides of the stabilized voltage power supply body, the first protection mechanism includes a positioning screw, a mounting block, a protection Frame and dust-proof net, the bottom of the regulated power supply body is provided with a second protection mechanism; this patent is used to improve the heat dissipation performance of the regulated power supply by setting a cooling device, accelerate the heat dissipation speed of the regulated power supply, and set the first protection mechanism , to prevent dust from entering the inside of the regulated power supply from the heat dissipation holes and affecting the operation of the regulated power supply, and a second protection mechanism is set to play a buffer role to prevent the regulated power supply from falling vertically from a high place and causing direct damage , but the technical solution provided by this patent is to directly fix and connect the protective frame of the power supply through bolts, which is inconvenient to take and use the adjustable DC regulated power supply inside, which is relatively cumbersome
