In addition, during the carrying process of the power converter, the interface is also easily subjected to physical impact and friction, causing the interface to deform or damage, reducing the service life of the power converter. On the other hand, the existing power converter often does not have a device for fixing with the power strip, causing the power converter to easily shake during use, even causing unstable connection with the power strip and falling off, affecting charging safety and reducing user experience.

[0004] Therefore, it is necessary to provide a new power converter shell to solve the above technical problems. UTILITY MODEL CONTENT

[0037] It should be noted that the middle of the sleeve plate 9 is fixedly connected with the middle of the first spring 8, so that the first spring 8 can be prevented from deviating during use, use is affected, the sleeve plate 9 is prevented from being in contact with the through groove 13, and then the sliding of the inner rod 4 is affected;

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The limiting structure comprises a second spring 10, a limiting column 11 and a pressing rod 12, the inside of the rotating connection position of the shell 1 and the outer rod 3 and the inside of the top end of the inner rod 4 are all fixedly connected with the second spring 10, the end, which is far away from each other, of the second spring 10 is fixedly connected with the limiting column 11, the end, which is far away from each other, of the limiting column 11 is fixedly connected with the pressing rod 12, the longitudinal section of the limiting column 11 is designed as a square, the longitudinal section of the pressing rod 12 is designed as a cylinder, the diameter of the longitudinal section of the pressing rod 12 is equal to the length of the side of the longitudinal section of the limiting column 11, and the two ends of the outer rod 3 and the baffle 5 are all provided with square recesses 15; the longitudinal section size of the square recess 15 is same to the longitudinal section size of the limiting column 11.

[0039] It should be noted that the limiting column 11 can be inserted into the square recess 15 to limit the baffle 5, the pressing rod 12, which is symmetrically and slidingly connected with the top end of the inner rod 4, is extruded, the pressing rod 12 is close to each other, then the limiting rod is close to each other, the limiting rod is gradually separated from the square recess 15 and extrudes the second spring 10, when the limiting rod is completely separated from the square recess 15, the inner wall of the square recess 15, which is provided at the two ends of the baffle 5, is in contact with the side of the pressing rod 12, and the baffle 5 can rotate around the axis of the pressing rod 12.

[0040] The working principle of the power converter shell is as follows:

[0041] Adjusting the inner rod 4 to stretch out and shrink back:

[0042] The push plate 6 at the top end of the outer rod 3 is symmetrically and slidably connected internally. Since the push plate 6 is fixedly connected with the clamping plate 7, the push plate 6 will drive the clamping plate 7 to approach each other when the push plate 6 approaches each other, at this time, the first spring 8 between the two clamping plates 7 is compressed, the middle part of the sleeve plate 9 is fixedly connected with the middle part of the first spring 8, which plays a role in preventing the first spring 8 from deviating and ensures the stability of the adjusting structure. As the clamping plates 7 approach each other, they will gradually be separated from the clamping grooves 14 equidistantly arranged on both sides of the through groove 13 on the side surface of the inner rod 4. The design of the through groove 13 on the side surface of the inner rod 4 and the sleeve plate 9 ensures the rationality of the structure. In the direction of the long axis of the cross section of the inner rod 4, the length of the sleeve plate 9 is less than the length of the through groove 13, so as to avoid the contact between the sleeve plate 9 and the through groove 13 affecting the sliding of the inner rod 4. Moreover, the sleeve plate 9 is designed to be hollow, so that the push plate 6 and the clamping plate 7 can smoothly slide on the inner wall thereof. After the clamping plate 7 is separated from the clamping groove 14, the inner rod 4 is no longer limited and can freely slide inside the outer rod 3. The user can slide the inner rod 4 to a suitable position according to actual needs. When the inner rod 4 reaches the ideal position, the compression on the push plate 6 is released, the first spring 8 is reset due to the elastic restoring force, the two clamping plates 7 are driven to move away from each other, the clamping plate 7 is re-clamped into the clamping groove 14 on the side surface of the inner rod 4, and the position of the inner rod 4 is limited, so as to prevent the inner rod 4 from being randomly slid during use.

[0043] Rotation and limiting of the outer rod 3 and the baffle 5:

[0044] When the outer rod 3 needs to be rotated, the pressing rod 12 inside the rotating connection between the shell 1 and the outer rod 3 is compressed. Since the pressing rod 12 is fixedly connected with the limiting column 11, the pressing rod 12 will drive the limiting column 11 to approach each other, the limiting column 11 will gradually be separated from the square recess 15 arranged at both ends of the outer rod 3 and will compress the second spring 10. When the limiting column 11 is completely separated from the square recess 15, the outer rod 3 is no longer limited by the limiting column 11 and can be rotated around the rotating connection with the shell 1. After the user rotates the outer rod 3 to a suitable angle, the pressing rod 12 is released, the second spring 10 is reset due to the elastic restoring force, the limiting column 11 is driven to move away from each other, and is re-inserted into the square recess 15 at both ends of the outer rod 3, so as to fix the position of the outer rod 3 and limit its continuous rotation.

[0045] When the baffle 5 needs to be rotated, the pressing rod 12 at the top end of the inner rod 4 is compressed. Similarly, the pressing rod 12 drives the limiting column 11 to approach each other, the limiting column 11 is separated from the square recess 15 arranged at both ends of the baffle 5 and compresses the second spring 10. When the limiting column 11 is completely separated from the square recess 15, the baffle 5 is no longer limited and can be rotated around the rotating connection with the inner rod 4. After the user rotates the baffle 5 to a suitable angle, the pressing rod 12 is released, the second spring 10 is reset, the limiting column 11 is re-inserted into the square recess 15 at both ends of the baffle 5, so as to fix the position of the baffle 5 and limit its continuous rotation.

[0049] Fix the converter:

[0050] In order to stably fix the power converter on the power strip, further operation can be performed, extrude the pressure rod 12 at the top end of the inner rod 4 to rotate the baffle 5 by 270°, so that the baffle 5 and the inner rod 4 form a right angle, then extrude the pressure rod 12 at both ends of the bottom of the outer rod 3 to rotate the outer rod 3 to be vertical downward, then adjust the inner rod 4 to make the inner rod 4 shrink, until the right angle formed by the baffle 5 and the inner rod 4 is fitted with the right angle at the bottom of the power strip, realize clamping and fixing, fix the shell on the surface of the power strip, prevent the converter from shaking or falling off during use;

[0051] Reset after use: after use, first pull out the conductive sheet 2 from the power strip, pull out the charging line, then extrude the corresponding pressure rod 12, rotate the outer rod 3 and the baffle 5 respectively to reset them, then extrude the push plate 6 to adjust the inner rod 4 to shrink, so that the baffle 5 is tightly fitted with the top of the shell 1, and the USB-A interface 16 and the USB-C interface 17 are shielded, complete the reset of the entire device, and facilitate storage and next use.
