Description

Technical Field

[0001] The utility model relates to the technical field of power supply external equipment, in particular to a dual-output direct current power supply. Background Art

[0002] With the rapid development of modern science and technology, the demand for power supply of various electronic devices has become increasingly diversified and sophisticated. Among them, dual-output DC power supply is widely used in industrial control, communication equipment, scientific research experiments and other fields because it can provide two different voltage levels of DC power at the same time.

[0003] The Chinese patent publication number is CN215528872U, which discloses a dual-output DC power supply. The dual-output DC power supply is provided with a bottom mounting groove, a bottom plate, a spring, a top plate, a guide rod and a soft pressure block. When the power supply is installed in the bottom mounting groove of the bottom shell, the hand is placed on the push handle, and then the top plate is pushed toward the bottom plate position, and then the spring is compressed. At this time, the power supply is placed between the two top plates, and then the push handle is released to reset the spring, so that the soft pressure block on the top plate is pressed on the side of the power supply, and the power supply is fixed in the bottom mounting groove. The guide rod cooperates with the through hole on the top plate, so that the top plate can only move in one direction. Through the cooperation of the bottom plate, the spring and the top plate, the power supply can be quickly installed.

[0004] The above technical solution has the following shortcomings: On the one hand, when installing the power supply, the device still needs to push the top plate manually, and the power supply needs to be placed between the two top plates before the push handle can be released. The installation method is time-consuming and labor-intensive, which reduces work efficiency. On the other hand, the shell structure specifications of the device for installing the power supply are fixed, and it is impossible to install and replace power supplies of different sizes, resulting in the inability to flexibly configure the power supply and update and upgrade when facing different application scenarios or changes in equipment requirements. Therefore, it is necessary to propose a dual-output DC power supply to solve the above-mentioned problems. Utility Model Content

[0008] Furthermore, in order to achieve the clamping of power supply bodies of different thicknesses on the adjustment seat, the height adjustment frame mechanism includes lifting grooves on the surfaces of clamping plates one and two, a threaded transmission rod is rotatably installed at the bottom of the lifting groove, a sliding block is threadedly connected to the surface of the threaded transmission rod, and a lifting clamping plate is fixedly connected to one end of the sliding block. The lifting clamping plate is driven up and down by the rotation of the threaded transmission rod to clamp and limit the power supply bodies of different thicknesses on the surface of the adjustment seat.

[0009] Furthermore, in order to reduce the friction between the transverse transmission rod and the longitudinal transmission rod and the side surface of the lifting limit block, sliding grooves are opened on each side surface of the lifting limit block, and one end of the transverse transmission rod and the longitudinal transmission rod is fixedly installed with a movable pulley, and the movable pulley is rotatably installed in the sliding groove. Through the rolling of the movable pulley in the sliding groove, the pressing block drives the lifting limit block to move downward more labor-saving.

[0010] Furthermore, in order to achieve shock absorption when clamping plate 1 and clamping plate 2 are contracted and clamped, shock-absorbing rubber pads are fixedly installed on one side surface of clamping plate 1 and clamping plate 2, and the shock-absorbing rubber pads can provide shock absorption protection for the power supply body when it is clamped.

[0011] Furthermore, in order to realize the power supply of the power supply device, a power supply body is installed on the surface of the adjustment seat, output interfaces are fixedly installed on both sides of the surface of the power supply body, and control interfaces are fixedly installed on both sides of the output interface. Through the installation and disassembly of the power supply body, different power supply bodies can be replaced in the device, and the power supply body can be controlled to release power to the outside world through the output interface and the control interface.

[0012] Furthermore, in order to facilitate the rotation of the threaded transmission rod, a twisting rod is fixedly connected to the top of the threaded transmission rod.

[0013] Furthermore, in order to facilitate the movement of the power supply device as a whole, hand pull rings are fixedly installed at both ends of the support base plate, and the support base plate is lifted and pulled through the hand pull rings.

[0014] Furthermore, in order to realize the output of electricity to the outside after the power supply body is installed, an output hole is opened on the surface of the clamping plate one, and the output hole cooperates with the output interface. A connector is fixedly installed on the one side surface of the clamping plate two, and the connector cooperates with the control interface. An adjustment knob is rotatably installed on the surface of the clamping plate two. After the power supply body is installed between the clamping plates one and two, the output interface passes through the output hole to output power to the outside. After the connector is installed in the control interface, the current and voltage output by the power supply body are controlled by adjusting the knob.

[0015] The beneficial effects of the utility model are:

[0016] 1. After placing the power supply body on the surface of the adjustment seat and the pressing block, the pressing block and the lifting limit block are pressed downward by the gravity of the power supply body to squeeze the reset spring to shrink it. When the shrinkage hole 1 and the shrinkage hole 2 on the surface of the lifting limit block and the pressing block move to the position matching the transverse transmission rod and the longitudinal transmission rod, the transverse transmission rod and the longitudinal transmission rod quickly enter the shrinkage hole 1 and the shrinkage hole 2 through the elastic force of the shrinkage spring 1 and the shrinkage spring 2, thereby driving the clamping plate 1 and the clamping plate 2 to quickly clamp the power supply body on the surface of the adjustment seat, thereby realizing the quick installation of the power supply body and making the installation of the power supply body more convenient.

[0017] 2. The transverse transmission rod and the longitudinal transmission rod use the elastic force of the surface contraction spring 1 and the contraction spring 2 to enable the clamping plate 1 and the clamping plate 2 to clamp and limit the power supply body on the surface of the adjustment seat. When the transverse transmission rod and the longitudinal transmission rod are contracted, they are slidably installed in the contraction hole 1 and the contraction hole 2, and can slide to change the distance they extend outward, thereby clamping and installing power supply bodies of different sizes and dimensions, and realizing the replacement and use of power supply bodies of different specifications by the power supply device.
