However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details given herein, that the present application can be practiced with other than the described embodiments, and that variations from the particular embodiments described herein can be made and still be within the scope of the present application.

[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. The "in one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0029] Embodiment 1

[0030] Reference Figures 1-7 For the first embodiment of the present application, the embodiment provides a high-frequency UPS power supply with good heat dissipation effect. The high-frequency UPS power supply with good heat dissipation effect comprises a main body assembly 100 and a protection assembly 200. The three can protect the cooling fan from dust when idle, facilitate subsequent normal rotation and heat dissipation, and enable individual opening of the corresponding protection plate during maintenance, on-demand opening of a single protection plate during use, prolonging the service life and ensuring the heat dissipation effect.

[0031] The main body assembly 100 comprises a power supply 101. The power supply 101 is provided with a cooling fan 102 on one side. The cooling fan 102 is provided with a filter screen 103 on one side. The filter screen 103 is fixed to one side of the power supply 101.

[0032] The power supply 101 is a high-frequency UPS power supply. The power supply 101 converts mains power into stable AC power output through power conversion, automatic control, energy storage management and communication functions, can cope with mains fluctuations and power outages, and provides uninterrupted stable power protection for power supply reliability requirements of power equipment in places. The cooling fan 102 can timely discharge the heat generated by the internal electronic components of the power supply 101 during operation, maintain a suitable temperature environment, and ensure stable operation of the power supply 101. The number of filter screens 103 is two, which are arranged on one side of the cooling fan 102. The filter screen 103 can block external dust, debris and other impurities, preventing these impurities from entering the cooling fan 102 and the power supply 101 along with the air.

[0033] The protection assembly 200 is arranged on one side of the filter screen 103, and comprises a protection piece 201. The protection piece 201 comprises a protection plate 201a arranged on one side of the filter screen 103. A sliding strip 201b is fixed on one side of the protection plate 201a. A rotating frame 201c is arranged on the outer side of the sliding strip 201b. The sliding strip 201b and the rotating frame 201c are movably connected. A connecting rod 201d is hingedly connected to one side of the rotating frame 201c. An activity plate 201e is hingedly connected to one end of the connecting rod 201d. A threaded rod 201f is inserted into the bottom of the activity plate 201e. A rotating shell 201g is arranged on one end of the threaded rod 201f.

[0034] The protection piece 201 is arranged in two groups and arranged on one side of the filter screen 103. The protection plate 201a can be used to close the heat dissipation fan 102 and prevent dust from accumulating on the surface of the heat dissipation fan 102 when not in use. A driving groove corresponding to the sliding strip 201b is formed in the rotating frame 201c. When the protection plate 201a needs to be moved, the threaded rod 201f is rotated. The threaded rod 201f and the activity plate 201e are screw-connected. The rotation of the threaded rod 201f drives the activity plate 201e to move. The movement of the activity plate 201e drives the connecting rod 201d to move. The connecting rod 201d drives the rotating frame 201c to rotate. The rotation of the rotating frame 201c drives the driving groove to move and press the sliding strip 201b to move. The movement of the sliding strip 201b drives the protection plate 201a to move, so that the protection plate 201a can be opened or closed. The rotating shell 201g is arranged to connect the two threaded rods 201f to move at the same time, so that the two threaded rods 201f can be rotated at the same time. When one of the protection plates 201a needs to be moved, the rotating shell 201g is moved to separate the rotating shell 201g from one of the threaded rods 201f, so that the threaded rod 201f can be rotated.

[0035] When in use, if the protection plate 201a needs to be opened or closed to close or open the heat dissipation fan 102, the following steps can be performed.

[0036] If the two groups of protection plates 201a need to be opened or closed at the same time, the rotating shell 201g is moved to connect the two threaded rods 201f. One of the threaded rods 201f is rotated. Since the threaded rod 201f and the activity plate 201e are screw-connected, the rotation of the threaded rod 201f drives the activity plate 201e to move. The movement of the activity plate 201e drives the connecting rod 201d to move. The connecting rod 201d drives the rotating frame 201c to rotate. The driving groove on the rotating frame 201c moves and presses the sliding strip 201b to move, so that the sliding strip 201b moves and finally drives the protection plate 201a to be opened or closed synchronously.

[0037] If only one set of protective plates 201a needs to be moved, first move the rotating shell 201g to separate it from one of the threaded rods 201f, and then rotate the threaded rod 201f, which can control the opening or closing of the set of protective plates 201a according to the above transmission principle, so as to realize the protection operation of the cooling fan 102 under different needs, prevent dust accumulation, and ensure the normal operation of the cooling fan 102 and the power supply 101.

[0058] Embodiment 3

[0059] Reference Figures 1-7 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.

[0060] Specifically, the movable block 203f is fixed with a moving strip 204b on one side, and the moving strip 204b is fixed with a pulling disc 204c at one end.

[0061] When it is desired to release the limiting of the rotating shell 201g, the limiting block 204a is separated from the limiting groove by moving the moving strip 204b, so that the limiting of the rotating shell 201g can be released, and then the rotating shell 201g is driven to return to the original position by the rebounding force of the first spring 203d, and the pulling disc 204c is convenient for the user to move the moving strip 204b.

[0062] Specifically, the moving strip 204b is sleeved with a pressing disc 204d on the outside, the pressing disc 204d is fixed with a second spring 204e on one side, and the second spring 204e is fixed at one end in the inner wall of the movable block 203f.

[0063] When the moving strip 204b is moved, the pressing disc 204d can be moved, and the second spring 204e can be pressed by the movement of the pressing disc 204d. At this time, the limiting block 204a is separated from the limiting groove. When the moving strip 204b is released, the limiting block 204a can return to the original position by the elastic force of the second spring 204e for next use.

[0064] Specifically, the moving strip 204b is sleeved with the protection tube 204f, and the protection tube 204f is movably connected with the moving strip 204b.

[0065] The protection tube 204f is fixed on one side of the movable block 203f, and the moving strip 204b can be supported by the protection tube 204f to prevent the moving strip 204b from deviating.

[0066] In use, when it is needed to open or close the two groups of protection plates 201a simultaneously to protect the heat dissipation fan 102, first, the rotating shell 201g is moved to connect the two threaded rods 201f. Then, one of the threaded rods 201f is rotated, and the movable plate 201e is moved due to the threaded connection between the threaded rod 201f and the movable plate 201e. The movable plate 201e is moved to move the connecting rod 201d, and the connecting rod 201d is further moved to rotate the rotating frame 201c. When the rotating frame 201c is rotated, the driving groove formed in the rotating frame 201c is moved to press and move the sliding strip 201b, and finally the protection plate 201a is opened or closed synchronously to realize the protection or opening of the heat dissipation fan 102 as a whole, to ensure the normal operation and prevent dust accumulation.

[0067] If only one group of protection plates 201a needs to be moved, the rotating shell 201g is moved to separate from one of the threaded rods 201f. Then, the threaded rod 201f is rotated, and the protection plate 201a is opened or closed according to the transmission principle described above, to meet the specific protection requirements of the heat dissipation fan 102 in different use scenarios.

[0068] During the movement of the protection plate 201a, the protection plate 201a moves the sliding block 202a in the sliding groove of the positioning disc 202b. The positioning disc 202b is fixed on one side of the power supply 101. Through such sliding cooperation, the protection plate 201a can be supported to effectively prevent the protection plate 201a from deviating during movement.

[0069] Meanwhile, the connecting rod 201d applies a torsional force to the torsional spring 202d during movement. When the connecting rod 201d needs to return to the original position, the torsional force of the torsional spring 202d can support the connecting rod 201d to assist it to return to the corresponding position.

[0070] When the rotating shell 201g is to be operated to control the rotation of the threaded rods 201f, moving the rotating shell 201g will cause the connecting groove to be separated from the first clamping strip, at which time rotating one of the threaded rods 201f will cause the first rotating column 203a to rotate, but will not cause the rotating shell 201g to rotate. When the connecting groove is again clamped with the first clamping strip, the rotation of the first clamping strip will cause the rotating shell 201g to rotate, thereby causing the second rotating column 203b to rotate and causing the other threaded rod 201f to rotate.

[0071] When the rotating shell 201g is moved, the first spring 203d will be compressed, and when the operation is released, the force of the rebound of the first spring 203d will cause the rotating shell 201g to return to its original position, so that the connecting groove is clamped with the first clamping strip again, facilitating subsequent operation and use.

[0072] By moving the movable block 203f, the driving ring 203e can be moved, and the movement of the driving ring 203e can cause the rotating shell 201g to move, thereby achieving the corresponding control operation.

[0073] If the rotating shell 201g is not to be returned to its original position by the first spring 203d, the limiting block 204a can be moved to be clamped with the limiting groove, so as to limit the rotating shell 201g.

[0074] When it is necessary to release the limiting of the rotating shell 201g, the moving strip 204b is moved, one end of the moving strip 204b is fixed with the pull plate 204c, which facilitates the operation of the user, and the movement of the moving strip 204b will cause the limiting block 204a to be separated from the limiting groove, thereby releasing the limiting of the rotating shell 201g, and then relying on the rebound force of the first spring 203d to cause the rotating shell 201g to return to its original position. When the moving strip 204b is moved, the pressing disc 204d will be moved, the movement of the pressing disc 204d will exert a compressive force on the second spring 204e, and when the moving strip 204b is released, the rebound force of the second spring 204e can cause the limiting block 204a to return to its original position, so as to facilitate the limiting operation and use next time. And the moving strip 204b is sleeved with the protective tube 204f on the outside, the protective tube 204f is fixed on one side of the movable block 203f, which can support the moving strip 204b and prevent it from deviating.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
