Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, specifically to an outdoor disconnecting switch with stable connection. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power supplies, switching operations, and connecting and disconnecting small-current circuits, without arc-extinguishing functionality. When in the open position, the disconnecting switch has an insulation distance between its contacts that meets specified requirements and a clear disconnection mark. When in the closed position, it can carry current under normal circuit conditions and current under abnormal conditions (such as short circuits) for a specified time. Disconnecting switches are mostly installed outdoors, but the outdoor environment is unpredictable. This necessitates ensuring a stable connection of the disconnecting switch to guarantee stable circuit connections. Therefore, a stable outdoor disconnecting switch is proposed to better ensure stable circuit connections.

[0003] As disclosed in patent announcement number CN222546197U, a stable outdoor disconnect switch includes a mounting bracket and a connecting mechanism, wherein the connecting mechanism is provided on one side of the surface of the mounting bracket. This is a stable disconnect switch device.

[0004] Although it achieves the setup of bushing, bracket, connecting plate, support plate, contact point, fastening bolt, copper wire and contact block, when an outdoor disconnect switch is required, first install the copper wire threaded into the support plate, and then thread the support plate onto the bracket. After installation, the contact block on the copper wire is set inside a pair of connecting plates. Then connect the pair of connecting plates with fastening bolts. During the fastening process, the contact points set on the connecting plates will move towards each other, causing the contact points to move toward the side wall of the contact block. When one side of the contact point is in contact with the contact block, the connection is completed.

[0005] However, this does not solve the problem that existing disconnect switches are not conducive to flexible adjustment of installation position during use, nor to limiting and fixing the connection between terminals, which affects the stability of the line connection and the safety during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stable outdoor disconnect switch, comprising a protective box and a base. The protective box contains the base, and the top of the base has three sets of input terminals spaced at equal intervals. A limit seat is provided between two sets of input terminals, and a support seat is provided between the other two sets of input terminals. A placement plate is provided inside the protective box on one side of the base. Three sets of output terminals are spaced at equal intervals on one side wall of the placement plate. A lead screw is movably installed on the other side wall of the placement plate. A sliding rod is provided on the side wall of the placement plate on the side of the lead screw. The lead screw is threadedly connected to the support seat, and the sliding rod is slidably connected to the limit seat. A handle is provided at the end of the lead screw away from the placement plate. A screw is provided inside the handle, and the screw is threadedly connected to the handle and the base respectively. A mounting post is provided outside the protective box, and an integrated frame is provided on the outer wall of the protective box.

[0008] Preferably, a bearing arm is mounted on the surface of the mounting column, and a connecting block is provided at the end of the bearing arm away from the mounting column.

[0009] Preferably, the connecting block is provided with a first locking pin at one end near the bearing arm, and the connecting block is movably connected to the bearing arm through the first locking pin.

[0010] Preferably, a connecting seat is provided at the end of the connecting block away from the bearing arm, and a second locking pin is provided at the end of the connecting seat near the connecting block. The connecting seat is movably connected to the connecting block through the second locking pin, and the connecting seat is connected to the protective box.

[0011] Preferably, the integrated frame is symmetrically provided with limit rods inside, and each limit rod has a slider symmetrically slidably provided on its surface.

[0012] Preferably, the limiting rod surface on one side of the slider is provided with a spring, and the two ends of the spring are respectively connected to the slider and the integrated frame.

[0013] Preferably, each slider is provided with a linkage arm on its side wall, and each linkage arm is provided with a hinge shaft at the end near the slider, and the linkage arm is movably connected to the slider through the hinge shaft.

[0014] Preferably, the integrated frame is provided with a protective cover, and the end of the linkage arm near the protective cover is provided with a linkage shaft, and the linkage arm is movably connected to the protective cover through the linkage shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the disconnecting switch not only realizes flexible adjustment of the installation position and facilitates the limiting and fixing of the connection between terminals, but also improves the stability of the line connection and the safety during use;

[0016] (1) Move the device to the installation position, connect the mounting column to the mounting base, loosen the first locking pin, rotate the connecting block, and the connecting block can drive the protective box to rotate and adjust its installation position through the connecting seat. Then tighten the first locking pin to fix the connecting block to the bearing arm. Loosen the second locking pin, rotate the connecting seat, and the connecting seat can drive the protective box to rotate to adjust the installation position of the protective box again, so as to adapt to different installation positions. Connect the input terminal to the input wire, connect the output terminal to the output wire, rotate the handle, drive the screw to rotate, drive the placement plate to move, and drive the output terminal to move so that the output terminal and the input terminal are in contact and the circuit is closed. Then insert the screw into the handle, rotate the screw, and fix the handle to the base so that the output terminal and the input terminal are kept in the closed state to ensure the stable connection between the lines, thereby improving the stability of the line connection. It realizes flexible adjustment of the installation position, facilitates the limit fixation of the connection between the terminals, and improves the stability of the line connection.

[0017] (2) Due to the complex outdoor environment, there may be situations where foreign objects hit the protective box, such as bird strikes. When a foreign object hits the protective box, it first hits the surface of the protective cover and causes the protective cover to move. The protective cover drives the linkage arm to rotate through the linkage shaft. The linkage arm drives the slider to slide on the surface of the limit rod through the hinge shaft. The slider drives the spring to contract and deform. Under the elastic cooperation of the spring, the force is offset to avoid damage to the protective box caused by the impact of foreign objects, thus improving the safety of the disconnect switch during use.

[0025] Please see Figure 1-5 An embodiment of this utility model provides: a stable outdoor disconnect switch, including a protective box 4 and a base 5. The protective box 4 is provided with the base 5 inside. The top of the base 5 is provided with three sets of input terminals 6 at equal intervals. A limit seat 25 is provided between two sets of input terminals 6. A bearing seat 12 is provided between the other two sets of input terminals 6. A placement plate 8 is provided inside the protective box 4 on one side of the base 5. Three sets of output terminals 7 at equal intervals are provided on the side wall of one side of the placement plate 8. A lead screw 9 is movably installed on the side wall of the placement plate 8 on the side of the lead screw 9. A sliding rod 13 is provided on the side wall of the placement plate 8 on the side of the lead screw 9. The lead screw 9 is threadedly connected to the bearing seat 12. The sliding rod 13 is slidably connected to the limit seat 25. A handle 10 is provided at the end of the lead screw 9 away from the placement plate 8. A screw 11 is provided inside the handle 10. The screw 11 is threadedly connected to the handle 10 and the base 5 respectively. A mounting post 1 is provided outside the protective box 4. An integrated frame 14 is provided on the outer wall of the protective box 4.

[0026] A bearing arm 2 is mounted on the surface of the mounting column 1, and a connecting block 22 is provided at the end of the bearing arm 2 away from the mounting column 1.

[0027] A first locking pin 23 is provided at one end of the connecting block 22 near the bearing arm 2, and the connecting block 22 is movably connected to the bearing arm 2 through the first locking pin 23;

[0028] A connecting seat 3 is provided at the end of the connecting block 22 away from the bearing arm 2. A second locking pin 24 is provided at the end of the connecting seat 3 near the connecting block 22. The connecting seat 3 is movably connected to the connecting block 22 through the second locking pin 24. The connecting seat 3 is also connected to the protective box 4.

[0029] First, move the device to the installation position, connect the mounting column 1 to the mounting base, loosen the first locking pin 23, and rotate the connecting block 22. The connecting block 22 will then drive the protective box 4 to rotate and adjust its installation position via the connecting seat 3. Then, tighten the first locking pin 23 to fix the connecting block 22 to the bearing arm 2. Loosen the second locking pin 24 and rotate the connecting seat 3. The connecting seat 3 will then drive the protective box 4 to rotate, further adjusting its installation position to accommodate different installation locations. Connect the input terminal 6 to the input wire and the output terminal 7 to the output wire. Rotate the handle 10, which will drive the lead screw 9 to rotate. The lead screw 9 is connected to the bearing seat 12 via a thread. With the movable cooperation of lead screw 9 and placement plate 8, and the sliding cooperation of slide rod 13 and limit seat 25, lead screw 9 drives placement plate 8 to move, and placement plate 8 drives output terminal 7 to move, so that output terminal 7 contacts input terminal 6, thus closing the circuit. Then, screw 11 is inserted into handle 10 and screw 11 is rotated. With the threaded connection between screw 11, handle 10 and base 5, handle 10 and base 5 are fixedly connected, so that output terminal 7 and input terminal 6 are kept in a closed state, so as to ensure stable connection between the lines, thereby improving the stability of the line connection. It realizes flexible adjustment of installation position, facilitates the limit fixation of connection between terminals, and improves the stability of line connection.

[0030] The integrated frame 14 has symmetrically arranged limit rods 15 inside, and the surfaces of the limit rods 15 are symmetrically slidably provided with sliders 17.

[0031] Springs 18 are provided on the surface of the limiting rod 15 on one side of the slider 17, and the two ends of the springs 18 are respectively connected to the slider 17 and the integrated frame 14.

[0032] Each slider 17 has a linkage arm 20 on its side wall. Each linkage arm 20 has a hinge shaft 16 at the end near the slider 17. The linkage arm 20 is movably connected to the slider 17 through the hinge shaft 16.

[0033] The integrated frame 14 is provided with a protective cover 19, and the linkage arm 20 is provided with a linkage shaft 21 at one end near the protective cover 19, and the linkage arm 20 is movably connected to the protective cover 19 through the linkage shaft 21.

[0034] Due to the complex outdoor environment, there may be instances of foreign objects impacting the protective box 4, such as bird strikes. When a foreign object impacts the protective box 4, it first strikes the surface of the protective cover 19 and causes the protective cover 19 to move. The protective cover 19 then drives the linkage arm 20 to rotate via the linkage shaft 21. The linkage arm 20 then drives the slider 17 to slide on the surface of the limit rod 15 via the hinge shaft 16. The slider 17 then causes the spring 18 to contract and deform. With the elastic cooperation of the spring 18, this force is offset, preventing damage to the protective box from the impact of foreign objects and improving the safety of the disconnect switch during use.

[0035] Working principle: Move the device to the installation position, connect the mounting column 1 to the mounting base, loosen the first locking pin 23, rotate the connecting block 22, and the connecting block 22 will drive the protective box 4 to rotate and adjust its installation position through the connecting seat 3. Then tighten the first locking pin 23 to fix the connecting block 22 to the bearing arm 2. Loosen the second locking pin 24, rotate the connecting seat 3, and the connecting seat 3 will drive the protective box 4 to rotate, thereby adjusting the installation position of the protective box 4 again to adapt to different installation positions. Connect the input terminal 6 to the input wire, and connect the output terminal 7 to the output wire. Rotate the handle 10, which will drive the lead screw 9 to rotate. With the lead screw 9 threadedly connected to the bearing seat 12, and with the lead screw 9 moving in conjunction with the placement plate 8, and with the sliding contact between the slide rod 13 and the limit seat 25, the lead screw 9 drives the placement plate 8 to move, and the placement plate 8 drives the output terminal 7 to move, thereby adjusting the output terminal. When terminal 7 contacts input terminal 6, the circuit is closed. Then, screw 11 is inserted into handle 10 and screw 11 is rotated. With the screw 11 connected to handle 10 and base 5 by threads, handle 10 and base 5 are fixedly connected, so that output terminal 7 and input terminal 6 are kept in a closed state to ensure a stable connection between the lines and improve the stability of the line connection. Due to the complex outdoor environment, there may be situations where foreign objects hit the protective box 4, such as bird strikes. When a foreign object hits the protective box 4, it first hits the surface of the protective cover 19 and moves the protective cover 19. The protective cover 19 drives the linkage arm 20 to rotate through the linkage shaft 21. The linkage arm 20 drives the slider 17 to slide on the surface of the limit rod 15 through the hinge shaft 16. The slider 17 drives the spring 18 to contract and deform. With the elastic cooperation of the spring 18, the force is offset to avoid damage to the protective box caused by the impact of foreign objects.
