DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Those skilled in the art can understand that, unless specifically stated, the singular forms "a", "an" and "said" used herein also include the plural forms. It should be further understood that the word "comprise" used in the specification of the present application means that the features, integers, steps, operations, elements and / or components exist, but does not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0024] Please refer to Figures 1-4 As shown, a power distributor convenient for maintenance is provided, which comprises a base plate 1, a housing 2 and an inner core module 3. A coaming 4 is arranged on the top of the base plate 1. A plurality of quick connection mechanisms 5 are arranged in the range of the coaming 4. The inner core module 3 is installed in the range of the coaming 4 and is movably connected with the quick connection mechanisms 5. The housing 2 is a frame structure with an open bottom. The housing 2 is installed on the top of the base plate 1.

[0025] The quick connection mechanism 5 is a separable mechanism with an upper half part and a lower half part. The upper half part is fixedly connected with the bottom of the inner core module 3, and the lower half part is fixedly connected with the base plate 1. When maintenance is performed, the upper and lower parts of the quick connection mechanism 5 can be separated after the housing 2 is removed. It should be noted that the connection of the quick connection mechanism 5 is not limited by the housing 2. The housing 2 only serves the purpose of protection and appearance.

[0026] The inner side of the fence 4 is provided with a guide pipe 6 with internal thread, a bolt 7 is arranged in the guide pipe 6, the bottom plate 1 and the shell 2 are fixedly connected by the bolt 7, and it should be noted that when the bolt 7 is fully tightened, the bolt 7 passes through the guide pipe 6, at this time the end of the bolt 7 reaches below the upper half of the quick connection mechanism 5, and here the bolt 7 not only has the effect of connecting the shell 2 and the bottom plate 1, but also serves as a limiting piece to limit the downward movement of the quick connection mechanism 5, which is equivalent to limiting the quick disassembly effect of the quick connection mechanism 5.

[0027] As shown in Figure 3 and Figure 4 The quick connection mechanism 5 includes an outer sleeve 501, an inner shaft 502, an upper vertebral body 503, a lower vertebral body 504, a mounting groove 505, a spring 506, and a tongue pin 507. The outer sleeve 501 is a hollow tubular structure, and its top is fixedly connected with the bottom of the inner core module 3. The inner shaft 502 is located at the axis of the outer sleeve 501 and is fixedly connected with the bottom plate 1 at the bottom.

[0028] The inner shaft 502 is a stepped structure, and its upper part is thin in diameter. The upper vertebral body 503 and the lower vertebral body 504 are located in the thin upper part and can move up and down along the upper part of the inner shaft 502. It is worth noting that there is a gap between the upper vertebral body 503 and the lower vertebral body 504. The top diameter of the upper vertebral body 503 is smaller than the bottom diameter. The top diameter of the lower vertebral body 504 is the same as the bottom diameter of the upper vertebral body 503, and the bottom diameter of the lower vertebral body 504 is the same as the top diameter of the upper vertebral body 503.

[0029] The mounting groove 505 is formed on the inner wall of the outer sleeve 501, and the tongue pin 507 is arranged in the mounting groove 505 through the spring 506. The end of the tongue pin 507 connected with the spring 506 is a cylindrical structure, and the other end is a wedge-shaped structure.

[0030] Please refer to Figure 3 and Figure 4 shown, Figure 3 The state shown is a cross-sectional view of the quick connection mechanism 5 in a normal connection state. In this state, the tongue pin 507 is clamped in the gap between the upper vertebral body 503 and the lower vertebral body 504 under the action of the spring 506. At this time, the outer sleeve 501 is clamped and cannot be pulled out, thus realizing the connection and locking effect of the quick connection mechanism 5.

[0031] Figure 4The state shown in the figure is the state when the quick connecting mechanism 5 is disassembled, and it can be seen that at this time the outer sleeve 501 is pressed down, and in this process, since the bottom of the tongue pin 507 is a wedge-shaped structure, with the pressing down of the outer sleeve 501, the tongue pin 507 gradually shrinks inward and presses the spring 506, and finally shrinks into the mounting groove 505, and with the continuous pressing down of the outer sleeve 501, since the lower vertebral body 504 is a circular truncated cone structure which is wide at the top and narrow at the bottom, the tongue pin 507 is again ejected under the action of the spring 506, at this time the outer sleeve 501 is moved upward, the tongue pin 507 will move upward along with the inner shaft 502, and in this movement process, the tongue pin 507 is pressed by the lower vertebral body 504 and shrinks into the mounting groove 505 again, when the top of the lower vertebral body 504 contacts the bottom of the upper vertebral body 503, the tongue pin 507 completely shrinks into the mounting groove 505, and with the continuous upward movement of the outer sleeve 501, the tongue pin 507 is again ejected along the inclined surface of the upper vertebral body 503, at this time the quick disassembly of the quick connecting mechanism 5 is completed;

[0032] It should be noted that, as can be seen from Figure 4 , if the bolt 7 is not unscrewed at this time, the bolt 7 will stay below the outer sleeve 501 and hinder the downward movement of the outer sleeve 501, that is, in the normal use state, the bolt 7 is not only a connecting piece of the shell 2 and the bottom plate 1, but more importantly, it is a limiting piece to prevent the downward movement of the outer sleeve 501 and prevent the inner core module 3 from being separated from the bottom plate 1.

[0033] As shown in Figure 1 and Figure 2 :

[0034] The shell 2 and the surrounding plate 4 are both provided with screw holes corresponding to the bolt 7, one end of the bolt 7 can pass through the guide pipe 6 and extend below the outer sleeve 501; one end of the shell 2 is also provided with a wiring port 8, the top of which is provided with a distribution interface 9 corresponding to the inner core module 3, and the top of the shell 2 is also provided with a power-off switch 10; rubber sealing washers are arranged at the wiring port 8 and the distribution interface 9.

[0035] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
