Detailed Implementation

[0034] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a switch cabinet frame structure 100 includes two or more layers of frames 110 and support members 120. Each frame 110 includes two connected horizontal bars 111 and two vertical bars 112. One of the horizontal bars 111 and vertical bars 112 has a first limiting groove 113 at both ends, and the other has a first limiting member 114 at both ends that mates with the first limiting groove 113. The two or more layers of frames 110 are arranged side-by-side along a plane perpendicular to the plane containing the frames 110. The first limiting groove 113 has a first opening 1131 along a plane perpendicular to the plane containing the frames 110 and a... A second opening 1132 is provided parallel to the first limiting member 114 and cooperates with the first limiting member 114. The first limiting member 114 has two oppositely arranged second limiting grooves 115 that cooperate with the second opening 1132 along the plane perpendicular to the frame 110. Both ends of the support member 120 are provided with second limiting members 121. The two second limiting members 121 cooperate with the corresponding two second limiting grooves 115 to connect the two adjacent frames 110. The support member 120 is connected to the horizontal bar 111 and / or the vertical bar 112 through the connector 140.

[0036] Two or more frames 110 are arranged side by side along a plane perpendicular to the direction of the frame 110. That is, multiple frames 110 can be arranged side by side along the height direction. The arrangement can be set according to actual needs, such as two-layer, three-layer, four-layer, or five-layer frames 110. Adjacent frames 110 are connected by support members 120.

[0037] The frame 110 consists of two vertical rods 112 and two horizontal rods 111, all arranged opposite each other. The vertical rods 112 are connected to adjacent horizontal rods 111 to form the frame 110 structure. The connection between the vertical rods 112 and the horizontal rods 111 is achieved through the engagement of a first limiting member 114 and a first limiting groove 113. In some embodiments, the horizontal rods 111 have first limiting grooves 113 at both ends, and the vertical rods 112 have first limiting members 114 at both ends. The first limiting members 114 can be limiting blocks, meaning they can be inserted into the horizontal rods 111 to connect the horizontal rods 111 and the vertical rods 112. In some embodiments, on the plane where the frame 110 is located, the first limiting member 114 can be set parallel to or perpendicular to the vertical rod 112. Correspondingly, the direction of the second opening 1132 is parallel to the direction of the first limiting member 114, as long as the first limiting member 114 cooperates with the first limiting groove 113.

[0038] In other embodiments, the horizontal bar 111 has first limiting members 114 at both ends, and the vertical bar 112 has first limiting grooves 113 at both ends. The first limiting members 114 can be limiting blocks, meaning they can be inserted into the vertical bar 112 to connect the horizontal bar 111 and the vertical bar 112. In some embodiments, on the plane of the frame 110, the first limiting members 114 can be parallel to or perpendicular to the horizontal bar 111. Correspondingly, the direction of the second opening 1132 is parallel to the direction of the first limiting member 114, as long as the first limiting member 114 cooperates with the first limiting groove 113.

[0039] Both ends of the support member 120 are provided with second limiting members 121 that cooperate with the second limiting groove 115. That is, the support member 120 can connect two adjacent frames 110. In order to ensure the stability of the overall connection, the support member 120 is connected to the horizontal bar 111 and / or the vertical bar 112 through the connector 140, which can connect and fix the frame 110 to the support frame, thereby forming a multi-layer frame 110 structure. In some embodiments, for the convenience of installation and disassembly, the support member 120 is detachably connected to the horizontal bar 111 and / or the vertical bar 112 through the connector 140.

[0040] Therefore, the switchgear frame structure 100 of this application is simple. The entire structure is a single-layer frame 110, which connects the horizontal bars 111 and vertical bars 112 in the frame 110 through the cooperation of the first limiting member 114 and the first limiting groove 113. Adjacent frames 110 are connected by support members 120, wherein the support member 120 is connected to the two adjacent frames 110 through the cooperation of the second limiting member 121 and the second limiting groove 115. In order to ensure the stability of the overall structure, the support member 120 is connected to the horizontal bar 111 and / or the vertical bar 112 through the connector 140. Compared with the prior art, the frame 110 structure of this application can be installed with fewer bolts 142, and the assembly is quick and firm, with high assembly efficiency of the overall frame 110.

[0041] like Figure 2 and Figure 3 As shown, in order to divide the middle of the frame 110, in some embodiments, one or more third limiting grooves 116 are provided on the opposite side of the two crossbars 111, and the third limiting grooves 116 are arranged in a direction parallel to the support member 120; the switch cabinet frame structure 100 also includes a baffle assembly 130, which is connected to at least one of the third limiting grooves 116. The baffle assembly 130 can cooperate with the third limiting grooves 116 to divide the overall frame 110 structure into multiple areas to meet various usage requirements.

[0042] In other embodiments, one or more third limiting grooves 116 are provided on the opposite side of the two vertical rods 112, so that the vertical rods 112 or the horizontal rods 111 can be separated according to actual usage requirements.

[0043] In some embodiments, the barrier assembly 130 includes a third limiting member 131, a sliding member 132, and a barrier member 133. The third limiting member 131 is limited by a third limiting groove 116; the sliding member 132 is connected to the third limiting member 131 and slidably connected to the third limiting groove 116, and the sliding member 132 is provided with a sliding groove; the barrier member 133 is at least partially slidably engaged with the sliding groove.

[0044] In some implementations, the partition 133 includes a vertical baffle 1331 and a horizontal baffle 1332 hinged to the vertical baffle 1331; the vertical baffle 1331 is vertically arranged, and the horizontal baffle 1332 is horizontally arranged. The vertical baffle 1331 and the horizontal baffle 1332 are hinged to facilitate the installation and removal of the vertical baffle 1331 and the horizontal baffle 1332. The vertical baffle 1331 can divide the horizontal section, and the horizontal baffle 1332 can divide the vertical section, which can be set according to the actual situation.

[0045] like Figure 5 and Figure 6As shown, in some embodiments, the vertical baffle 1331 is slidably connected to the sliding groove, and the horizontal baffle 1332 is connected to the vertical rod 112 through the fixing component 117. That is, the installation of the barrier component 130 can be achieved simply by inserting the vertical baffle 1331 along the sliding groove, connecting the vertical baffle 1331 to the horizontal baffle 1332, and connecting the horizontal baffle 1332 to the vertical rod 112 through the fixing component 117.

[0046] In some embodiments, grooves 1121 are provided on opposite sides of the two vertical rods 112; the fixing assembly 117 includes an elastic member 1171 connected to the inner wall of the groove 1121 and a fourth limiting member 1172 connected to the elastic member 1171. The fourth limiting member 1172 can contact or separate from the bottom of the horizontal baffle 1332 under the action of the elastic member 1171. The horizontal baffle 1332 can be limited and installed by squeezing the elastic member 1171, which is convenient to operate.

[0047] In some embodiments, the fourth limiting member 1172 is trapezoidal, and its long parallel side contacts or separates from the bottom of the horizontal baffle 1332. That is, by squeezing the elastic member 1171, the long parallel side of the fourth limiting member 1172 separates from the bottom of the horizontal baffle 1332, thus no longer supporting the horizontal baffle 1332; or, under the force of the elastic member 1171 alone, the long parallel side of the fourth limiting member 1172 contacts the bottom of the horizontal baffle 1332, thus supporting the horizontal baffle 1332, making operation convenient.

[0048] In some embodiments, the sum of the total length of the elastic member 1171 after maximum compression deformation and the length of its parallel side with the fourth limiting member 1172 is less than the depth of the groove 1121. The fourth limiting member 1172 supports the horizontal baffle 1332; that is, the parallel side of the fourth limiting member 1172 supports the horizontal baffle 1332. Pressing the fourth limiting member 1172 along the extension / retraction direction of the elastic member 1171 compresses the elastic member 1171, thus pushing the fourth limiting member 1172 fully into the groove 1121. At this time, the horizontal baffle 1332, no longer supported by the fourth limiting member 1172, can hang down to one side of the vertical baffle 1331, allowing the upper and lower spaces to be connected as needed, thereby creating a larger usable space. When the fourth limiting member 1172 is no longer subjected to external force, it can be reset using the elastic member 1171.

[0049] In some embodiments, the lengths of the vertical bar 112, the horizontal bar 111, and the support bar can be set as needed, as long as the actual requirements are met.

[0050] In some embodiments, the length of the vertical rod 112 is less than the length of the horizontal rod 111. Both ends of the vertical rod 112 are provided with first limiting members 114 in a direction parallel to the vertical rod 112. The horizontal rod 111 has a first limiting groove 113 in a direction parallel to the vertical rod 112. Since the length of the vertical rod 112 is less than the length of the horizontal rod 111, and the first limiting members 114 protrude from the vertical rod 112, it eliminates the need to add additional first limiting members 114 to the already relatively long horizontal rod 111, thus preventing the horizontal rod 111 from becoming excessively long and facilitating transportation. Furthermore, the first limiting members 114 extend in a direction parallel to the vertical rod 112, and the extension direction of the first limiting members 114 is parallel to the extension direction of the vertical rod 112, making disassembly and handling more convenient. Compared to the first limiting member 114 being set parallel to the crossbar 111, the first limiting member 114 is essentially bent, which takes up more space after disassembly and is inconvenient for transportation.

[0051] In some embodiments, the vertical baffle 1331 and the horizontal baffle 1332 are detachably connected. The vertical baffle 1331 can be removed as needed, leaving only the horizontal baffle 1332. The end of the horizontal baffle 1332 is supported by the fixing component 117, thereby forming a larger space for use.

[0052] To ensure the stability of the overall frame 110 structure, in some embodiments, the connector 140 includes a hinge 141 and a bolt 142. In some embodiments, a hinge 141 is fixedly connected to one side of the support member 120, and a bolt 142 is threadedly connected to the inner side of the hinge 141. The bolt 142 is threadedly connected to the horizontal frame 110 rod. After assembling the horizontal rod 111, vertical rod 112, and support member 120 in the frame 110, the hinge 141 on one side of the support member 120 can be fixed to the horizontal rod 111 by the bolt 142, thus fixing the connection between the frame 110 and the support member 120.

[0053] In a second aspect of this application, a switch cabinet is provided, including the switch cabinet frame structure 100 described above. Since the switch cabinet frame structure 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

In the entire structure, the single-layer frame 110 is connected to the horizontal bar 111 and the vertical bar 112 through the cooperation of the first limiting member 114 and the first limiting groove 113. Adjacent frames 110 are connected by support members 120, wherein the support member 120 is connected to the two adjacent frames 110 through the cooperation of the second limiting member 121 and the second limiting groove 115. In order to ensure the stability of the overall structure, the support member 120 is connected to the horizontal bar 111 and / or the vertical bar 112 through the connector 140.
