Description

Technical Field

[0001] The invention relates to the technical field of direct current power supplies, and in particular to a wall-mounted direct current power supply. Background Art

[0002] A DC power supply is a device that maintains a constant voltage and current in a circuit. Such as dry batteries, storage batteries, DC generators, etc. A DC power supply has two electrodes, positive and negative. The positive electrode has a high potential and the negative electrode has a low potential. When the two electrodes are connected to the circuit, a constant potential difference can be maintained between the two ends of the circuit, thereby forming a current from the positive electrode to the negative electrode in the external circuit. A DC power supply is an energy conversion device that converts other forms of energy into electrical energy to supply the circuit in order to maintain a constant flow of current.

[0003] In the prior art, some DC power supplies are equipped with wall-mounted mechanisms, and the existing wall-mounted mechanisms are only installed and fixed by means of a mounting plate, a mounting groove and a mounting plate fixed at the installation position. Therefore, this installation method will, on the one hand, cause the DC power supply itself to vibrate when the DC power supply is working, thereby causing the DC power supply as a whole to shake or vibrate relative to the installation position (such as a wall), causing the mounting plate to loosen relative to the installation surface, thereby causing the DC power supply to fall. On the other hand, since the DC power supply needs to be inspected and maintained, the DC power supply needs to be removed. However, in the prior art, it is not convenient and quick to install and remove the DC power supply from the installation position, and the operation is still performed in a blind spot between the DC power supply and the installation position. In particular, it is difficult to quickly align the connecting components on the DC power supply with the connecting components on the installation position during installation, thereby increasing the difficulty of installing the DC power supply.

[0035] In the above technical solution, by utilizing the active trigger disk 41 rotatably connected to the bottom end of the power supply body 4, the power supply body 4 can still be flipped after being placed on the mounting base 3; by utilizing the active trigger disk 41 on the power supply body 4, after the power supply body 4 is placed on the mounting base 3, the active trigger disk 41 can press the passive trigger disk 52 through the gravity of the power supply body 4 itself, and at this time, when the passive trigger disk 52 slides, the multiple clamping parts 55 can move along the first guide groove 31 in the direction close to the active trigger disk 41, so that the multiple clamping parts 55 are abutted on the circumference of the active trigger disk 41, thereby playing the role of clamping the active trigger disk 41 on the power supply body 4, thereby achieving the role of being able to fix the power supply body 4 on the mounting base 3; by using the mounting base 3 to install the power supply body 4, the power supply body 4 will not vibrate during operation, thereby playing the effect of being able to reduce the vibration of the power supply body 4 running on the mounting base 3.

[0036] Furthermore, a plurality of heat dissipation fans 43 are fixedly mounted on the power source body 4 .

[0037] In the above technical solution, by using the heat dissipation fan 43 , when the power supply body 4 is in operation, the heat dissipation fan 43 can be used to dissipate heat from various electronic components inside the power supply body 4 .

[0038] Furthermore, a plurality of legs 44 are fixedly mounted on the bottom end of the power source body 4 , and the plurality of legs 44 are all arranged on the top surface of the mounting base 3 .

[0039] In the above technical solution, the legs 44 are used to support the power source body 4 placed on the mounting base 3 .

[0040] Specifically, a plurality of limiting slide bars 522 are slidably inserted on the mounting base 3 , and the bottom ends of the plurality of limiting slide bars 522 are fixedly connected with a connecting plate 521 , and each connecting plate 521 is fixedly connected to the circumferential surface of the passive trigger disk 52 .

[0041] In the above technical solution, by utilizing the limiting slide bar 522, the passive trigger disk 52 can slide along the direction of multiple limiting slide bars 522 when pressed by the active trigger disk 41, thereby achieving the effect of limiting the sliding direction of the passive trigger disk 52.

[0042] Specifically, the top ends of the plurality of limit sliding rods 522 are fixedly connected to the limit blocks 523 , and the cross section of the limit blocks 523 is circular or square.

[0043] In the above technical solution, the limiting block 523 is used to prevent the passive trigger disk 52 from sliding off the mounting base 3 when the passive trigger disk 52 slides under the pressure of the active trigger disk 41.

[0044] Specifically, the passive clamping mechanism 5 also includes a clamping assembly 56 for limiting the sliding of the passive trigger disk 52. The clamping assembly 56 includes a plurality of sliding plates 562 slidably arranged on the bottom surface of the mounting base 3. A third elastic unit 564 is arranged between each sliding plate 562 and the mounting base 3. A clamping block 563 is fixedly connected to one side of the plurality of sliding plates 562 close to the passive trigger disk 52. A plurality of clamping grooves 524 are provided on the peripheral surface of the passive trigger disk 52 to engage with each clamping block 563. Chamfering is performed between the clamping block 563 and the clamping groove 524.

[0045] In the above technical solution, by utilizing the clamping assembly 56, when the passive trigger disk 52 slides downward under the action of the active trigger disk 41, through the interaction between the passive trigger disk 52 and the clamping block 563, the clamping block 563 can move in the direction away from the passive trigger disk 52 under the squeezing of the passive trigger disk 52. When the passive trigger disk 52 slides to the point where the clamping block 563 corresponds to the clamping groove 524, the elastic force of the third elastic unit 564 can be used to enable the clamping block 563 to be inserted into the clamping groove 524 opened at the corresponding position on the passive trigger disk 52 under the action of the elastic force of the third elastic unit 564, thereby playing a role in limiting the sliding of the passive trigger disk 52.

[0047] In the above technical solution, by utilizing a compression spring, after the passive trigger disk 52 slides to the same horizontal plane as the clamping block 563, the clamping block 563 can move toward the passive trigger disk 52 under the action of the elastic force of the compression spring, and then multiple clamping blocks 563 are respectively inserted into the clamping grooves 524 opened at corresponding positions on the passive trigger disk 52, thereby limiting the sliding of the passive trigger disk 52.

[0048] Furthermore, an operating rod 565 is slidably inserted on the support plate 561 , one end of the operating rod 565 is fixedly connected to the sliding plate 562 , and the other end is fixedly connected to an operating handle 566 .

[0049] In the above technical solution, by utilizing the operating rod 565, when it is necessary to disassemble the power supply body 4 on the mounting base 3 and to inspect and maintain the power supply body 4, by pulling the operating rod 565, the clamping block 563 on the sliding plate 562 can be moved in a direction away from the passive trigger disk 52 under the action of the operating rod 565, so that the clamping block 563 on the sliding plate 562 can be removed from the clamping groove 524 provided on the passive trigger disk 52. At this time, by lifting the power supply body 4, the power supply body 4 on the mounting base 3 can be quickly disassembled.

[0050] Specifically, a plurality of second guide grooves 32 are formed on the bottom surface of the mounting base 3 , and sliding members 567 are slidably disposed inside the plurality of second guide grooves 32 . The sliding members 567 are fixedly connected to the sliding plate 562 .

[0051] In the above technical solution, by utilizing the second guide groove 32 , it is possible to limit the sliding direction and sliding distance of the sliding plate 562 .

[0052] Specifically, a plurality of sliding frames 54 are slidably arranged on the top surface of the mounting base 3, and each clamping portion 55 is rotatably arranged on each sliding frame 54; a sliding seat 541 is fixedly arranged at the bottom end of each sliding frame 54, and each sliding seat 541 is slidably arranged in each first guide groove 31, and a first elastic unit 543 is arranged between each sliding seat 541 and each first guide groove 31.

[0053] In the above technical solution, by utilizing the sliding frame 54, the clamping portion 55 on the sliding frame 54 can be driven by the passive trigger disk 52 to move along the direction of the first guide groove 31 toward the active trigger disk 41, thereby enabling the clamping portion 55 on the sliding frame 54 to abut against the active trigger disk 41, thereby clamping the active trigger disk 41. By utilizing the first elastic unit 543, the clamping portion 55 on the sliding frame 54 can be reset.

[0054] As a preferred technical solution of this embodiment, a slider 542 is slidably disposed inside the first guide groove 31 , and two sides of the slider 542 are fixedly connected to the sliding frame 54 and the sliding seat 541 respectively.

[0055] In the above technical solution, by utilizing the slider 542 in the first guide, the sliding direction and sliding distance of the sliding frame 54 can be limited.

[0056] As a preferred technical solution of this embodiment, the first elastic unit 543 is a tension spring, one end of which is fixedly connected to the sliding seat 541 , and the other end of which is fixedly connected to the inner wall of the first guide groove 31 through a connecting block 544 .

[0057] In the above technical solution, by using the tension spring, when the power supply body 4 is removed from the mounting base 3, the elastic force of the tension spring can be used to reset the multiple clamping parts 55 and the passive trigger disk 52.

[0058] Specifically, a transmission assembly 53 is provided between the passive trigger disk 52 and each clamping portion 55, and the transmission assembly 53 includes: a connecting seat 531, which is fixedly connected to the bottom end of the passive trigger disk 52; a rotating seat 532, which is rotatably connected to the connecting seat 531; a telescopic rod 533, which is connected and arranged on the rotating seat 532, and the output end of the telescopic rod 533 is rotatably connected to the sliding seat 541.

[0059] In the above technical solution, by utilizing the transmission assembly 53, after the power supply body 4 is placed on the mounting base 3, the passive trigger disk 52 will slide downward under the pressure of the active trigger disk 41. At this time, by utilizing the transmission between the telescopic rod 533 and the sliding frame 54, the passive trigger disk 52 can slide downward, so that the clamping parts 55 on the multiple sliding frames 54 can move along the first guide groove 31 in the direction close to the active trigger disk 41, and then the clamping parts 55 on the multiple sliding frames 54 can clamp and limit the active trigger disk 41 on the power supply body 4, so that the power supply body 4 can be fixedly installed on the mounting base 3.

[0060] Specifically, the clamping portion 55 includes a rotating shaft rotatably set on the sliding frame 54, a cylindrical frame 551 is fixedly connected to the circumferential surface of the rotating shaft, a plurality of arc-shaped abutment plates 552 are slidably set on the circumferential surface of the cylindrical frame 551, and a second elastic unit 553 is set between each arc-shaped abutment plate 552 and the cylindrical frame 551; a locking assembly 57 for limiting the rotation of the power supply body 4 is set on the sliding frame 54.

[0062] As a preferred technical solution of this embodiment, a plurality of anti-slip stripes 554 are fixedly mounted on the arc-shaped abutment plate 552.

[0063] In the above technical solution, by utilizing the anti-slip stripes 554 on the arc-shaped abutment plate 552, the friction between the arc-shaped abutment plate 552 and the active trigger disk 41 is increased, so that the multiple clamping parts 55 can better clamp the active trigger disk 41 on the power supply body 4.

[0064] As a preferred technical solution of this embodiment, the second elastic unit 553 is a buffer spring, and two ends of the buffer spring are fixedly connected to the cylindrical frame 551 and the arc-shaped abutment plate 552 respectively.

[0065] In the above technical solution, the buffer spring is used to buffer the arc-shaped abutment plate 552 on the cylindrical frame 551, so as to avoid the situation in which the clamping part 55 on the sliding frame 54 slides under the action of the transmission assembly 53 and the clamping part 55 on the sliding frame 54 slides too fast, causing the clamping part 55 on the sliding frame 54 to collide with the active trigger disk 41 when it abuts against the active trigger disk 41.
