[0024] 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.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A modular low-voltage switchgear frame for quick assembly includes a base 1, a column 2 and a crossbeam 3. A splicing component 4 is provided at the connection between the base 1 and the column 2, and a splicing component 5 is provided at the connection between the column 2 and the crossbeam 3.
[0027] The splicing component 4 includes a positioning block 401 and an insert block 402. The bottom of the positioning block 401 is fixedly connected to the base 1. The side of the insert block 402 near the column 2 is fixedly connected to the column 2. The top of the positioning block 401 has a slot 403 that mates with the insert block 402. A spring 404 is fixedly connected to the inner wall of the positioning block 401 away from the column 2. A limit plate 405 is fixedly connected to the other end of the spring 404. A fixing block 406 is fixedly connected to the side of the limit plate 405 away from the spring 404. The side of the fixing block 406 away from the limit plate 405 passes through the positioning block 401 and extends into the inner cavity of the insert block 402. A pull rod 407 is fixedly connected to the side of the limit plate 405 away from the fixing block 406. The other end of the pull rod 407 passes through the outside of the positioning block 401 and is fixedly connected to a handle 408.
[0028] In this embodiment: by setting up a base 1, a column 2, a crossbeam 3, a first splicing component 4, and a second splicing component 5, when in use, the column 2 and the base 1 can be quickly spliced, assembled, and fixed by the first splicing component 4. The assembly and disassembly are relatively convenient, saving labor and improving work efficiency. The crossbeam 3 and the column 2 can be spliced, assembled, and fixed by the second splicing component 5. The assembly and disassembly operations are also relatively convenient.
[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the splicing component 2 5 includes a C-shaped block 501 and a locking block 502. The side of the C-shaped block 501 closest to the column 2 is fixedly connected to the column 2, and the side of the locking block 502 closest to the crossbeam 3 is fixedly connected to the crossbeam 3. The side of the locking block 502 closest to the inner wall of the C-shaped block 501 is in contact with the inner wall of the C-shaped block 501.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a handle 503 is provided at the bottom of the C-shaped block 501, and a fixing screw 504 is fixedly connected to the top of the handle 503. The top of the fixing screw 504 passes through the C-shaped block 501 and extends into the inner cavity of the locking block 502.
[0031] Specifically, such as Figure 2 , Figure 5 As shown, the bottom of the C-shaped block 501 is provided with a threaded hole 505 that cooperates with the fixing screw 504, and the bottom of the locking block 502 is provided with a threaded groove 506 that cooperates with the fixing screw 504. The surface of the fixing screw 504 is connected to the inner wall of the threaded hole 505 and the threaded groove 506 by threads on the side that is close to the inner wall of the threaded hole 505 and the threaded groove 506 respectively.
[0032] In this embodiment, by setting up a C-shaped block 501, a locking block 502, a throttle 503, a fixing screw 504, a threaded hole 505, and a threaded groove 506, in use, the crossbeam 3 is inserted into the groove of the C-shaped block 501 of the column 2 using the locking block 502, and then the fixing screw 504 is inserted into the threaded hole 505 of the C-shaped block 501 and the throttle 503 is rotated. The throttle 503 will drive the fixing screw 504 to rotate and move through the thread, so that the fixing screw 504 moves into the threaded groove 506 of the locking block 502, thereby connecting and fixing the locking block 502 and the C-shaped block 501, thus completing the splicing and assembly of the crossbeam 3 and the column 2. The operation is relatively convenient, and disassembly can be performed by reversing the operation.
[0033] Specifically, such as Figure 2 , Figure 3 As shown, the bottom edge of the insert 402 is arc-shaped, and the side of the insert 402 near the inner wall of the slot 403 contacts the inner wall of the slot 403. The side of the fixing block 406 away from the limiting plate 405 is inclined.
[0034] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, a square opening 6 is provided on the inner wall of the positioning block 401 near the column 2, which is used to cooperate with the fixing block 406. The surface of the fixing block 406 is slidably connected to the inner wall of the square opening 6. A fixing groove 7 is provided on the bottom of the side of the insertion block 402 away from the column 2, which is used to cooperate with the fixing block 406. The side of the fixing block 406 near the inner wall of the fixing groove 7 is in contact with the inner wall of the fixing groove 7.
[0035] In this embodiment: by setting the bottom edge of the insert 402 to be arc-shaped, it can be easily inserted into the slot 403. By setting the side of the fixing block 406 away from the limiting plate 405 to be inclined, the fixing block 406 can be automatically moved out of the slot 403 by squeezing the inclined surface of the fixing block 406 when the insert 402 is inserted into the slot 403. By setting the square through-hole 6, the fixing block 406 can pass through the positioning block 401 to move left and right, and the fixing block 406 can be limited to prevent the fixing block 406 from shaking. By setting the fixing groove 7, the fixing block 406 can be inserted to fix the position of the insert 402.
[0036] Specifically, such as Figure 4 As shown, a circular hole 8 is provided on the inner wall of the positioning block 401 near the handle 408 to cooperate with the pull rod 407, and the surface of the pull rod 407 is slidably connected to the inner wall of the circular hole 8.
[0037] Specifically, such as Figure 2As shown, a positioning rod 9 is fixedly connected to the bottom of the column 2, and positioning holes 10 that cooperate with the positioning rod 9 are opened at the four corners of the top of the base 1. The surface of the positioning rod 9 is in contact with the inner wall of the positioning hole 10.
[0038] In this embodiment: by setting a circular hole 8, the pull rod 407 can pass through the positioning block 401 and move left and right. By setting a positioning rod 9 and a positioning hole 10, the connection stability between the column 2 and the base 1 can be increased.
[0039] Working principle: When assembling the column 2 and the base 1, the column 2 can be inserted into the slot 403 of the positioning block 401 through the insert 402. At this time, the positioning rod 9 will also be inserted into the positioning hole 10. When the insert 402 enters the slot 403, it will press the inclined surface of the fixing block 406. The fixing block 406 will be pushed out of the slot 403 and drive the limiting plate 405 to press the spring 404. When the insert 402 is fully inserted into the slot 403, the fixing block 406 will be engaged with the insert 401. When the fixing groove 7 of block 402 is flush with the spring 404, the spring 404 will push the limiting plate 405 to move by the force released after compression. The limiting plate 405 will drive the fixing block 406 to insert into the fixing groove 7 of the insert block 402, thus fixing the insert block 402 and completing the splicing and assembly of the column 2 and the base 1. The operation is relatively convenient. When disassembling the column 2 and the base 1 later, simply pull the handle 408. The handle 408 will drive the limiting plate 405 to move through the pull rod 407. The limiting plate 405 will... Moving the fixing block 406 out of the fixing slot 7 of the insert block 402 cancels the fixing of the insert block 402. Then, the insert block 402 and the positioning rod 9 are pulled out from the slot 403 and the positioning hole 10 respectively, making it easy to disassemble the column 2 and the base 1. When assembling the crossbeam 3 and the column 2, the crossbeam 3 can be inserted into the groove of the C-shaped block 501 of the column 2 using the locking block 502. Then, the fixing screw 504 is inserted into the threaded hole 505 of the C-shaped block 501 and the handle is turned. 503, the throttle 503 will drive the fixing screw 504 to rotate and move through the thread, so that the fixing screw 504 moves into the threaded groove 506 of the locking block 502, thereby connecting and fixing the locking block 502 and the C-shaped block 501, thus completing the splicing and assembly of the crossbeam 3 and the column 2. The operation is relatively convenient, and disassembly can be performed by reversing the operation. By completing the splicing and assembly of the column 2 and the base 1 and the splicing and assembly of the crossbeam 3 and the column 2, the splicing and assembly of the entire low-voltage switchgear frame can be completed.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
