[0031] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0032] Example

[0033] As mentioned in the background technology, in the prior art, a plurality of through holes or louver grooves are usually opened on the end face of the cabinet door 10, or louvers are installed in combination with the filter cotton 1, but the filter cotton 1 needs to be replaced frequently, and the replacement and disassembly of the snap-on or bolt connection is relatively laborious, and frequent disassembly will cause serious wear of the snap-on, making the snap-on unstable and easy to fall off. Therefore, the inventor has improved the existing installation method, designed a new quick-release assembly and applied it to the ring network cabinet, which is explained in detail below with reference to the drawings.

[0034] First, the quick-release assembly is described in this embodiment, wherein Figure 1 and Figure 2The quick-release assembly includes a shell 2 for placing the filter cotton 1. The shell 2 is set to a square structure with a square internal space. The square filter cotton 1 is placed therein, and in order to facilitate the blocking and limiting of the filter cotton 1, a mounting shell 3 is movably connected to one side of the shell 2. The sides of the shell 2 opposite to the mounting shell 3 are both open, and the airflow can pass through the shell 2, the filter cotton 1 and the mounting shell 3 in sequence.

[0035] On the basis of the above structure, in order to ensure the stability of the filter cotton 1, a plurality of clamping plates 8 are provided on the side of the mounting shell 3 close to the shell 2, and the clamping plates 8 extend toward the side of the filter cotton 1 until they abut against the filter cotton 1, so as to limit the filter cotton 1 in the shell 2. In the present embodiment, there are four clamping plates 8 in total, and two are grouped together, and are arranged in parallel on the side of the mounting shell 3 close to the shell 2, and the width is smaller than the depth of the shell 2, so that after being placed on the filter cotton 1, the clamping plates 8 just abut against the filter cotton 1, which plays a limiting role while not squeezing and deforming the filter cotton.

[0036] In order to ensure that the airflow passes through the mounting shell 3, the Figure 5 The shell 2 includes a frame 21, and the frame 21 includes a plurality of criss-cross connecting rods 22 to form a mesh structure, and the airflow can pass through the shell 2 with the mesh structure. On the basis of the above structure, in order to ensure that the airflow is blown out of the mounting shell 3, a plurality of louvers 4 are arranged from top to bottom on the side of the mounting shell 3 away from the shell 2 to form a shutter shape, and the airflow can be blown out of the mounting shell 3 between two adjacent louvers 4.

[0037] As one of the main design points of this scheme, and also the main difference from the prior art, combined with Figure 2-Figure 4 , which makes it convenient to replace the filter cotton 1. The bottom end of the mounting shell 3 is hinged to the shell 2, and the upper end is connected to the shell 2 through a connecting piece 6, and the upper end of the mounting shell 3 can be fixed to or separated from the shell 2 through the connecting piece 6. In the prior art, most mounting shells 3 and the shell 2 are connected by a card connection or a bolt connection. When disassembling, it is necessary to use a tool to pry open the card connection position. High frequency of installation and disassembly will make the connection position loose. In this solution, through the setting of the connecting piece 6 and the connecting plate 5, it is only necessary to separate the connecting piece 6 from the connecting plate 5, and the mounting shell 3 can be rotated downward around the hinge point at the bottom to complete the disassembly of the mounting shell 3, and then the filter cotton 1 in the shell 2 can be replaced.

[0038] Specifically, the connecting member 6 includes a stud 61 threadedly connected to the upper end of the mounting shell 3, and the stud 61 is arranged through the shell 2, and a connecting plate 5 is arranged around the shell 2, and a threaded barrel 7 is arranged at the upper end of the connecting plate 5, and the threaded barrel 7 is arranged coaxially with the stud 61 to ensure that the stud 61 can rotate into and out of the threaded barrel 7, thereby achieving the fixing and separation of the mounting shell 3 and the shell 2. Secondly, in order to ensure that the stud 61 has a larger range of engagement, a limit block 6 is fixedly installed at the mounting shell 3 where the stud 61 is arranged. 3, and the thickness of the limit block 63 is greater than the wall thickness of the mounting shell 3 body 2, and the width here refers to the length along the movable direction of the stud 61, the limit block 63 is in contact with the threaded barrel 7, the stud 61 passes through the limit block 63, and the stud 61 and the limit block 63 are connected by threads. The setting of the limit block 63 expands the engagement range of the stud 61 and ensures the straightness of the stud 61. After the stud 61 is separated from the threaded barrel 7, the stud 61 always maintains a coaxial state with the threaded barrel 7, which facilitates the subsequent return of the stud 61 to the threaded barrel 7.

[0039] On the basis of the above structure, a pull ring 62 is installed at one end of the stud 61 away from the threaded tube 7. By setting the pull ring 62, the staff can hook the pull ring 62 by hand to drive the stud 61 to rotate, which reduces the use of tools and is convenient and quick.

[0040] The above is a detailed description of the quick-release assembly, and the inventor has applied the quick-release assembly to the cabinet door 10 of the ring main unit. The installation of the quick-release assembly and the ring main unit will be described in detail below.

[0041] First, the intelligent ring main unit includes a cabinet body 9, combined with Figure 6 A cabinet door 10 is provided on the front side of the cabinet body 9, and the quick-release assembly is installed at the position of the cabinet door 10. Specifically, a mounting opening 11 is provided at the cabinet door 10, and the end surface size of the shell 2 is consistent with the size of the mounting opening 11. The size described here is the cross-sectional area of ​​the two. During installation, the overall quick-release assembly is outside the mounting opening 11, and the shell 2 is pushed toward the mounting opening 11. Therefore, the installation shell 3 is located outside the cabinet door 10, and the shell 2 is located inside the cabinet door 10. In addition, in order to facilitate the fixing of the shell 2 and the cabinet door 10, the combination Figure 7 The shell 2 is installed with elastic plates 12 on both sides perpendicular to the open end surface. The connection method between the power meter and the cabinet door 10 in the prior art can be adopted. The movable end is facing the connecting plate 5 and inclined toward the outside of the shell 2. During installation, the shell 2 is pushed toward the installation opening 11 and pushed into the installation opening 11. During the pushing process, the edge of the installation opening 11 will compress the elastic plate 12. After the elastic plate 12 completely enters the inside of the cabinet door 10, it will reset due to its elasticity and be clamped on the inside of the cabinet door 10, so that the installation shell 3 and the connecting plate 5 are clamped on the outside of the cabinet door 10.

[0042] After the quick-release assembly is installed, when the filter cotton 1 needs to be replaced or cleaned, hold the pull ring 62 and rotate the stud 61 to separate it from the threaded tube 7, pull the pull ring 62 to drive the mounting shell 3 to rotate downward around the bottom hinge point, open the mounting shell 3, take out the filter cotton 1 for replacement or cleaning, then put the filter cotton 1 back into the shell body 2, pull the mounting shell 3 to reset it, and rotate the stud 61 to reset it into the threaded tube 7.
