[0007] The utility model is further configured as follows: two slots are provided on the top of the positioning sheet metal.
[0008] By adopting the above technical solution, through the setting of the slots, after the positioning mechanism and the power supply device are installed, the two power supply devices need to be assembled together. Therefore, during assembly, the two slots on the top of the positioning sheet metal connected to the bottom power supply device are used to clamp with the bottom support leg one and support leg two connected to the top power supply device.

After the positioning sheet metals are connected to the two power supply devices respectively, when the two power supply devices are connected in parallel, the support legs 1 and 2 at the bottom of the top positioning sheet metal are inserted into the two slots of the bottom positioning sheet metal. The support leg 1 at the bottom of the top positioning sheet metal presses the inclined surface to make the positioning block enter the inside of the guide groove. After the bottoms of the support legs 1 and 2 come into contact with the bottom positioning sheet metal, the inclined surface loses its squeezing force, and the positioning block compression spring rebounds to push the inclined surface into the inside of the positioning slot, thereby realizing self-locking of the upper and lower positioning sheet metals. By locking the upper and lower positioning sheet metals, it is possible to prevent the connection parts from being damaged when the top power supply device is moved when the parallel connection of the upper and lower power supply devices is not removed.
[0021] When the positioning circular groove and the positioning bead correspond, the positioning shaft compression spring pushes the positioning bead into the inside of the positioning circular groove to limit the positioning block. The upper and lower positioning sheet metals can be separated by pulling up the top power supply device, without removing the screws that fix the positioning sheet metal.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.
[0029] Example 1:
[0030] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 A positioning mechanism for a DC power supply device includes a positioning sheet metal 1, the bottom of the positioning sheet metal 1 is integrally processed with a support leg 1 2 and a support leg 2 3, a positioning slot 4 is provided on the side of the support leg 1 2 close to the support leg 2 3, a positioning block 5 is provided inside the positioning sheet metal 1, the interior of the positioning block 5 is fixedly connected to a positioning block compression spring 6 through a spring fixing member, one end of the positioning block compression spring 6 is fixedly connected to the positioning sheet metal 1 through a spring fixing member, one side of the positioning block 5 is integrally processed with an inclined surface 7, a sliding groove 8 is provided on the front of the positioning sheet metal 1, and the interior of the sliding groove 8 is slidably connected to a fixed member fixed to the positioning block 5 The convex block 9 for fixed connection is provided, and a positioning circular groove 10 is provided on the top of the positioning sheet metal 1. The interior of the positioning sheet metal 1 is provided with a positioning shaft 11, a positioning shaft compression spring 12 and a positioning bead 13 from top to bottom. The top of the positioning shaft 11 is slidably connected to the positioning sheet metal 1; by setting the positioning block 5 to slide inside the positioning block compression spring 6, after the positioning sheet metal 1 is connected to the two power supply devices respectively, when the two power supply devices are connected in parallel, the support legs 2 and 3 at the bottom of the top positioning sheet metal 1 are inserted into the two slots 14 of the bottom positioning sheet metal 1, and the support legs 2 at the bottom of the top positioning sheet metal 1 will squeeze Press the inclined surface 7 to make the positioning block 5 enter the inside of the guide groove 15. After the bottom of the support leg 1 2 and the support leg 2 3 are in contact with the bottom positioning sheet metal 1, the inclined surface 7 loses its extrusion force, and the positioning block compression spring 6 rebounds to push the inclined surface 7 into the inside of the positioning card slot 4, thereby realizing self-locking of the upper and lower positioning sheet metals 1. By locking the upper and lower positioning sheet metals 1, it is possible to prevent the damage to the connection parts when moving the top power supply device without removing the parallel connection of the upper and lower power supply devices. When disassembling, by pulling the protrusion 9 to slide inside the sliding groove 8, the protrusion 9 drives the positioning The positioning block 5 squeezes the positioning block compression spring 6 to separate the inclined surface 7 and the positioning slot 4. At the same time, the positioning circular groove 10 and the positioning bead 13 will correspond. Since the top positioning sheet metal 1 squeezes the positioning shaft 11, the positioning shaft 11 will apply force to the positioning shaft compression spring 12 to compress it and generate a rebound force. When the positioning circular groove 10 and the positioning bead 13 correspond, the positioning shaft compression spring 12 pushes the positioning bead 13 to fit into the inside of the positioning circular groove 10 to limit the positioning block 5. The upper and lower positioning sheet metals 1 can be separated by pulling up the top power supply device, without having to remove the screws that fix the positioning sheet metal 1.
[0031] Furthermore, two slots 14 are provided on the top of the positioning sheet metal 1 . Two slots 14 are provided on the top of the positioning sheet metal 1 .
[0032] Furthermore, the bottom of the positioning shaft 11 is fixedly connected to the positioning shaft compression spring 12 through a spring fixing part, the positioning bead 13 is located at the bottom end of the positioning shaft compression spring 12, and the positioning bead 13 is fixedly sleeved inside the positioning shaft compression spring 12. Through the arrangement of the positioning shaft 11, the positioning shaft compression spring 12 and the positioning bead 13, the positioning bead 13 is used to engage with the positioning circular groove 10; the positioning shaft compression spring 12 is used to generate a rebound force on the positioning bead 13; the positioning shaft 11 is used to apply force to the positioning shaft compression spring 12, so that the positioning shaft compression spring 12 can be in a compressed state with a rebound force.
[0033] Furthermore, a guide groove 15 is provided inside the positioning sheet metal 1, and the interior of the guide groove 15 is slidably connected to the positioning block 5. The setting of the guide groove 15 is used to guide the positioning block 5, so that the positioning block 5 is reset under the push of the positioning block compression spring 6, and the positioning block 5 enters the interior of the guide groove 15 when pressed down by the support foot 2.
[0034] Furthermore, the surface of the positioning block compression spring 6 is slidably connected to the interior of the positioning block 5, and the surface of the positioning shaft compression spring 12 is slidably connected to the interior of the positioning sheet metal 1. Through the sliding connection between the positioning block compression spring 6 and the interior of the positioning block 5, a guiding role is played for the compression and rebound of the positioning block compression spring 6; the positioning shaft compression spring 12 is slidably connected to the positioning sheet metal 1, which plays a guiding role for the compression and rebound of the positioning shaft compression spring 12.
[0035] Furthermore, a fixing plate 16 is provided on the back of the positioning sheet metal 1, and four screws 17 are provided inside the fixing plate 16. Four threaded grooves 18 threadedly connected to the screws 17 are opened on the back of the positioning sheet metal 1. Through the setting of the fixing plate 16, screws 17 and threaded grooves 18, the positioning block 5 is limited so that the positioning block 5 cannot be separated from the positioning sheet metal 1.
[0036] Furthermore, two mounting holes 19 are provided inside the positioning sheet metal 1 , and the positioning sheet metal 1 can be fixed to the DC power supply device by passing screws through the mounting holes 19 .
[0037] Brief description of the usage process:
[0038] For a single power supply device, at least four of the mechanisms are installed. Two sides of the single power supply device need to be screwed through the mounting holes 19 and two of the mechanisms are installed on the power supply device. After installation, they can be docked and connected in parallel.
[0039] For ease of understanding, a single mechanism connected to a top power supply device and a single mechanism connected to a bottom power supply device are used as examples;
[0040] First, align the support legs 1 (2) and 2 (3) at the bottom of the positioning sheet metal 1 connected to the top power supply device with the two slots 14 at the top of the positioning sheet metal 1 connected to the bottom power supply device;
[0041] After that, the top positioning sheet metal 1 pushes the support leg 1 2 and the support leg 2 3 to move downward. During the movement, the support leg 1 2 at the bottom of the top positioning sheet metal 1 will squeeze the inclined surface 7, so that the inclined surface 7 is subjected to force and thus squeezes the positioning block 5. When the positioning block 5 is squeezed, it squeezes the positioning block compression spring 6, so that the positioning block compression spring 6 is in a compressed state. After the bottoms of the support leg 1 2 and the support leg 2 3 at the bottom of the top positioning sheet metal 1 are completely in contact with the bottom positioning sheet metal 1, the top positioning sheet metal 1 will press down the positioning shaft 11, and the positioning shaft 11 will squeeze the positioning shaft compression spring 12, so that the positioning shaft compression spring 12 is in a compressed state.
[0042] At the same time, the inclined surface 7 will correspond to the positioning slot 4, and the support leg 2 will no longer apply force to the inclined surface 7. At this time, the positioning block compression spring 6 that is squeezed and in a compressed state will reset and push the inclined surface 7 to fit into the interior of the positioning slot 4 to complete self-locking. Since the length of the positioning block 5 inside the guide groove 15 is greater than the length of the distance between the positioning block 5 and the guide groove 15, the positioning block 5 and the positioning block compression spring 6 can support the pulling force of the top positioning sheet metal 1 to prevent the inclined surface 7 from separating from the positioning slot 4.
[0043] If two parallel power supply devices need to be disassembled and connected; by pulling the protrusion 9, the protrusion 9 slides inside the sliding groove 8. When the protrusion 9 moves, it drives the positioning block 5 and the positioning circular groove 10 on the top of the positioning block 5 to slide and drives the inclined surface 7 on one side of the positioning block 5 and the positioning card groove 4 to separate;
[0044] When the positioning circular groove 10 and the positioning bead 13 correspond, the compressed positioning shaft compression spring 12 can rebound and push the positioning bead 13 to be stuck in the interior of the positioning circular groove 10, thereby limiting the positioning block 5. After rebounding, the positioning shaft compression spring 12 still has the rebound force generated by compression, so it can support the positioning bead 13 from separating from the positioning circular groove 10.
[0045] After the positioning block 5 is limited, the positioning block 5 will be located inside the guide groove 15, and the side where the inclined surface 7 contacts the support leg 2 will be on the same horizontal line as one side of the guide groove 15;
[0046] Then, by lifting the power supply device upward, the power supply device drives the positioning sheet metal 1 and its bottom support leg 1 2 and support leg 2 3 to separate from the slot 14. During the separation process, support leg 1 2 will separate from the inclined surface 7, and the positioning shaft 11 inside the bottom positioning sheet metal 1 will lose the downward force exerted by the top positioning sheet metal 1. At this time, the positioning shaft compression spring 12 resets and pushes the positioning shaft 11 to reset. As the positioning shaft compression spring 12 resets, the extrusion force on the positioning bead 13 disappears, and as support leg 1 2 separates from the inclined surface 7, the positioning block compression spring 6 will rebound and push the positioning block 5 to reset.
[0047] Disassembly can be achieved by separating the upper and lower positioning sheet metals 1, and the positioning sheet metals 1 installed by screws on the top and bottom power supply devices do not need to be removed.
[0048] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
