[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] In this technical solution, a modular UPS access control power supply includes a mounting frame 1 and an access control body 2. The access control body 2 is installed on the upper end of the mounting frame 1. A pull-out power supply structure is installed on the lower wall of the access control body 2. The pull-out power supply structure includes a power supply frame 3, power supply contacts 4, power supply body 5, mounting plate 6, two limit plates 7, two limit holes 8, two first connecting pieces 9, and a sliding mounting assembly.

[0025] The power supply frame 3 is embedded in the lower side of the access control body 2, the power supply contact 4 is installed in the upper side of the power supply frame 3, the power supply body 5 is embedded in the power supply frame 3, the mounting plate 6 is fixedly installed in the lower end of the power supply body 5 and located on the lower wall of the access control body 2, the two limit plates 7 are respectively installed on the lower sides of the outer wall of the access control body 2, the two limit holes 8 are respectively opened on one side of the two limit plates 7, the two first connecting pieces 9 are respectively installed on one side of the lower wall of the two limit plates 7, and the sliding mounting assembly is installed on the lower wall of the mounting plate 6.

[0026] In this technical solution, when installing the access control body 2, the mounting bracket 1 is first fixed in the designated position with bolts, and the access control body 2 is installed through the mounting bracket 1. Then, the power supply body 5 is embedded in the power supply frame 3, so that the contact part of the power supply body 5 contacts the power supply contact 4 at the upper end of the power supply frame 3, and the power supply body 5 supplies power to the access control body 2. Then, the sliding mounting component at the upper end of the mounting plate 6 is screwed, and the two ends of the sliding mounting component are embedded into the limiting holes 8 at the upper end of the two limiting plates 7, connecting the mounting plate 6 and the access control body 2, thereby realizing the fixing operation of the power supply body 5.

[0027] In some technical solutions, reference Figure 1 The sliding mounting assembly includes a mounting base 10, an operating shaft 11, a gear 12, four guide frames 13, two moving rods 14, and two racks 15;

[0028] Mounting base 10 is fixedly installed at the center of the lower wall of mounting plate 6. One end of operating shaft 11 is movably embedded in mounting base 10. Gear 12 is fixedly installed on the upper end of operating shaft 11. Four guide frames 13 are respectively installed on both sides of the lower wall of mounting plate 6. The two ends of two moving rods 14 are movably embedded in the four guide frames 13. Two racks 15 are respectively installed on the side walls of the two moving rods 14 and mesh with the two sides of gear 12.

[0029] In this technical solution, when fixing the power supply body 5, the operating shaft 11 inside the mounting base 10 is turned, causing the operating shaft 11 and gear 12 to rotate inside the mounting base 10. Under the meshing action of the gear 12 and the two racks 15 on the side walls of the two moving rods 14, the two moving rods 14 and the two racks 15 are pushed to move outward within the four guide frames 13 until one end of the two moving rods 14 is respectively embedded in the two limiting holes 8, thus achieving the initial fixing operation of the power supply body 5. When it is necessary to disassemble the power supply body 5, simply turn the operating shaft 11 in the opposite direction to drive the two moving rods 14 to separate from the two limiting holes 8. Then the power supply body 5 can be taken out from the power supply frame 3 for disassembly and replacement.

[0030] In some technical solutions, reference Figure 1 Two movable rods 14 are respectively movably embedded in two limiting holes 8 at one end. Two second connecting pieces 16 are installed on one side of the lower wall of the two movable rods 14. Two guide strips 17 are installed on the lower wall of the two movable rods 14. A connecting hole is opened at the upper end of the first connecting piece 9 and a connecting hole is opened at the upper end of the second connecting piece 16.

[0031] When fixing the power supply body 5, the lock can be embedded in the connecting holes of the first connecting piece 9 and the second connecting piece 16 to lock the moving rod 14 and the limiting plate 7, ensuring the anti-theft effect of the power supply body 5. In addition, the two guide bars 17 cooperate with the guide frame 13 to fully ensure the movement stability of the moving rod 14.

[0032] Working principle:

[0033] When installing the access control unit 2, firstly, fix the mounting bracket 1 in the designated position with bolts, and then install the access control unit 2 using the mounting bracket 1. Next, embed the power supply unit 5 into the power supply frame 3, so that the contact part of the power supply unit 5 contacts the power supply contact 4 at the upper end of the power supply frame 3, and supply power to the access control unit 2 through the power supply unit 5. Turn the operating shaft 11 in the mounting base 10 to make the operating shaft 11 and the gear 12 rotate in the mounting base 10. Under the meshing action of the gear 12 and the two racks 15 on the side wall of the two moving rods 14, the two moving rods 14 and the two racks 15 are pushed to move outward in the four guide frames 13 until one end of the two moving rods 14 is respectively embedded in the two limiting holes 8, thus realizing the initial fixing operation of the power supply unit 5. When it is necessary to disassemble the power supply unit 5, simply turn the operating shaft 11 in the opposite direction to drive the two moving rods 14 to separate from the two limiting holes 8, and then the power supply unit 5 can be taken out in the power supply frame 3 for disassembly and replacement.
