[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] Reference Figure 1-Figure 3 According to an embodiment of the automatic delivery device of a backup power supply of the present invention, it includes a box body 11 and a backup power supply placed in the box body 11, the box body 11 is provided with a terminal 13 electrically connected to the backup power supply, and also includes an external cable 14, the end of the external cable 14 is equipped with an adapter head 15 that can cooperate with the terminal head 13, and also includes a snap assembly for locking the relative position of the adapter head 15 and the terminal head 13.

[0029] It also includes a control mechanism for controlling whether the backup power supply is working or not. In this embodiment, the control mechanism includes a voltage transformer, a relay contactor, a single-chip microcomputer and a circuit breaker installed in the box 11. When the adapter head 15 and the terminal head 13 are connected by the snap assembly, when the voltage transformer senses that the voltage of the working bus is weakened, the single-chip microcomputer can cut off the working power supply through the circuit breaker, and enable the backup power supply to supply power to the external cable 14 through the terminal head 13. This is a prior art and will not be repeated here.

[0030] In addition, in order to ensure the stability of the connection between the adapter head 15 and the terminal head 13 and avoid skewing and breakage, a panel 16 is provided on the box body 11. The panel 16 is mounted on the outside of the terminal head 13 and also includes two cover plates 17 symmetrically distributed front and back to enclose the panel 16. Semicircular grooves are provided in the sides of the two cover plates 17 that are close to each other. The number of semicircular grooves in each cover plate 17 is the same as the number of the terminal head 13. The two semicircular grooves at the same left and right positions can form a complete circular groove for accommodating the external cable 14. The cover plate 17 is fixed to the panel 16 by bolts.

[0031] In order to prevent the external cable 14 from being cut at the circular groove, a rubber layer is installed on the curved surface of the semicircular groove, and the rubber layer is attached to the external cable 14. The provision of the rubber layer enables the connection point to be waterproof.

[0032] In order to prevent the stability of the connection between the terminal head 13 and the adapter head 15 from being affected when the external cable 14 is dragged, a pressure plate is installed on the lower side of the cover 17. The pressure plate is pressed against the adapter head 15 to press the adapter head 15 onto the terminal head 13. When the external cable 14 is dragged, the pressure plate can cooperate with the snap assembly to ensure the reliability of the connection between the terminal head 13 and the adapter head 15.

[0033] In addition, in this embodiment, the snap-fit ​​assembly includes an outer cylinder 21 provided at the lower end of the adapter head 15, and three card slots are provided at equal angles on the outer curved surface of the outer cylinder 21. The upper end of the terminal head 13 is provided with an inner cylinder 22, and three mounting grooves facing the card slots are provided on the outer curved surface of the inner cylinder 22. A hook plate 23 is provided in the mounting groove, and the hook plate 23 can be hooked in the card slot.

[0034] During installation, the worker moves the adapter head 15 downward and inserts the inner cylinder 22 into the outer cylinder 21 . At this time, the hook plate 23 can be hooked into the slot, making it difficult for the adapter head 15 to be separated from the terminal head 13 .

[0035] In the second embodiment of the automatic delivery device of a backup power supply, in order to facilitate the controlled separation of the adapter head 15 and the terminal head 13, an unlocking component is also included, and the unlocking component includes a circular ring 24 that is sleeved on the outside of the terminal head 13, and the inner curved surface of the circular ring 24 is provided with ejection grooves with the same number as the card slots at equal angles, and the ejection groove is equipped with a top plate for ejecting the hook plate 23, and the top plate is slidably connected to the ejection groove, and the top plate extends to the outside of the outer curved surface of the circular ring 24, and in order to facilitate the staff to control the top plate, the top plate is provided with an arc plate 25 at one end outside the circular ring 24.

[0036] When unlocking, the staff drags the ring 24 upward and makes the top plate face the hook plate 23. Then the staff presses the arc plate 25 and pushes the top plate inward, so that the top plate pushes the hook plate 23 inward. At this time, the hook plate 23 is no longer in the slot, and the adapter head 15 can be pulled out upward and separated from the terminal head 13. The setting of the arc plate 25 enables the staff to control all the top plates in the ring 24 with one hand.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
