Description

Technical Field

[0001] This utility model relates to a frame line, belonging to the technical field of frame line technology. Background Technology

[0002] A frame circuit breaker is a mechanical switching device used to interrupt current. It is mainly used in low-voltage power distribution systems, especially in low-voltage incoming lines, bus couplers, and power distribution circuits for low-voltage large-capacity motors. Frame circuit breakers use frame wires during installation and use.

[0003] When using some frame wires, depending on the application scenario, two ordinary copper wires are sometimes soldered together. The shape of these ordinary copper wires does not change during soldering, and the two copper wires remain vertical after soldering. In some special applications, these copper wires need to be curved, and the fact that the soldered copper wires remain vertical makes them inconvenient to use. Therefore, we provide a frame wire to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a frame line, the specific technical solution of which is as follows:

[0005] A frame wire includes an outer shell, a limiting block connected to the outer surface of the outer shell, a transmission rod slidably connected inside the limiting block, a locking block threaded to the outer surface of the transmission rod, an air vent inside the transmission rod, an air blocking block connected inside the transmission rod, an airtight plug slidably connected inside the air blocking block, a transmission block connected to the upper surface of the airtight plug, a blocking block connected inside the transmission rod, and a support rod slidably connected inside the blocking block.

[0006] Preferably, a connecting rod is connected to the upper surface of the locking block, a torsion block is connected to the upper surface of the connecting rod, and a protective block is connected to the upper surface of the limiting block.

[0007] Preferably, the outer surface of the protective block is slidably connected to the outer surface of the locking block, and the bottom surface of the locking block is in contact with the upper surface of the limiting block.

[0008] Preferably, a positioning plate is connected to the upper surface of the transmission rod, and blocking blocks are connected to both ends of the support rod.

[0009] Preferably, the outer surface of the blocking block is slidably connected to the interior of the transmission rod, and the outer surface of the transmission block is slidably connected to the interior of the transmission rod.

[0010] Preferably, the upper surface of the air-blocking block is in contact with the bottom surface of the transmission block, and the support rod has an air vent inside.

[0011] Preferably, a spring is connected to the bottom surface of the positioning plate, and the end of the spring away from the positioning plate is connected to the upper surface of the transmission block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This frame line utilizes the cooperation between components such as transmission rods and support rods. First, the air inside the support rod expands when heated. As the copper wire is welded, the air inside the support rod also expands due to heat. The expanded air is discharged from the vent. After welding, the air returns to its original volume, causing the two transmission rods to move towards the center of the support rods. The movement of the transmission rods causes the locking block to move along with the limiting block, thus allowing the outer shell to deform autonomously after the copper wire cools. This allows the user to know the temperature of the outer surface of the outer shell, and also causes the copper wire inside the outer shell to bend. This is very convenient and solves the problem of inconvenient use of copper wires that remain vertical after welding.

[0014] 2. This frame utilizes the cooperation between components such as springs and torsion blocks. The springs can push the transmission block to move. When air is expelled from the transmission rod, the air can push the transmission block open, allowing the air to escape. After the air is expelled, the springs will push the transmission block back to its original position, preventing outside air from entering and thus avoiding interference with the movement of the transmission rod. The torsion block can rotate, and when it rotates, it moves the connecting rod. The movement of the connecting rod causes the locking block to rotate, thereby connecting the locking block and allowing it to be removed from the transmission rod. This facilitates the disassembly of one side of the transmission rod and is very convenient to use. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 - Figure 5 The system includes an outer shell 1, with a limiting block 2 connected to the outer surface of the outer shell 1. A transmission rod 3 is slidably connected inside the limiting block 2. The outer shell 1 can be fitted onto the outer surface of the copper wire. When the copper wire is welded, the welding temperature will also raise the temperature of the outer shell 1. The outer shell 1 will fix the position of the limiting block 2. When the limiting block 2 moves, it will move the outer shell 1, thereby changing the shape of the outer shell 1, which in turn changes the shape of the internal copper wire. The limiting block 2 will restrict the direction of movement of the transmission rod 3, so that the position of the transmission rod 3 will not deviate significantly.

[0023] The outer surface of the transmission rod 3 is threaded with a locking block 4, and the inside of the transmission rod 3 is provided with an air vent 5. The locking block 4 can be installed on the transmission rod 3 by rotation, and similarly, it can be removed from the transmission rod 3 by rotating the locking block 4. After the locking block 4 is installed on the transmission rod 3, when the transmission rod 3 moves, it will move the locking block 4 with it. The air inside the transmission rod 3 can be discharged through the air vent 5, and the outside air can also enter through this point, thereby maintaining the balance of internal and external air pressure.

[0024] An air-blocking block 6 is connected inside the transmission rod 3. An airtight plug 7 is slidably connected inside the air-blocking block 6. The transmission rod 3 fixes the position of the air-blocking block 6. The air-blocking block 6 can increase the thickness of the outer wall of the transmission rod 3 at this location. When the airtight plug 7 is inserted into the air-blocking block 6, it can completely seal this location, preventing the gas inside the transmission rod 3 from escaping to the outside. When the airtight plug 7 is pulled out from the air-blocking block 6, the gas can flow out from the air-blocking block 6.

[0025] The upper surface of the airtight plug 7 is connected to a transmission block 8. The transmission block 8 fixes the position of the airtight plug 7. When the transmission block 8 moves, it will move the airtight plug 7, thereby changing the position of the airtight plug 7 and making the position of the airtight plug 7 adjustable. The surface of the transmission block 8 has holes, and the gas in the transmission rod 3 can be discharged through these holes, so that the transmission block 8 will not obstruct the movement of air in the transmission rod 3.

[0026] The transmission rod 3 is internally connected to a blocking block 9, and a support rod 10 is slidably connected inside the blocking block 9. The transmission rod 3 fixes the position of the blocking block 9, and the blocking block 9 moves with the movement of the transmission rod 3. The blocking block 9 restricts the direction in which the support rod 10 can move, so that the position of the support rod 10 does not deviate significantly.

[0027] The upper surface of the locking block 4 is connected to a connecting rod 11, the upper surface of the connecting rod 11 is connected to a torsion block 12, and the upper surface of the limiting block 2 is connected to a protective block 13. The locking block 4 fixes the position of the connecting rod 11. When the connecting rod 11 moves, it will move the locking block 4 along with it. The connecting rod 11 fixes the position of the torsion block 12. When the torsion block 12 moves, it will move the connecting rod 11 along with it. The connecting rod 11 will send the torsion block 12 to a farther place, so as to facilitate the user to rotate the torsion block 12. The surface of the torsion block 12 is provided with protrusions. These protrusions facilitate the user to rotate the torsion block 12 and prevent the user's hand from slipping when rotating the torsion block 12. The limiting block 2 fixes the position of the protective block 13, so that the protective block 13 cannot move arbitrarily.

[0028] The outer surface of the protective block 13 is slidably connected to the outer surface of the locking block 4. The bottom surface of the locking block 4 is in contact with the upper surface of the limiting block 2. The protective block 13 restricts the position that the locking block 4 can move, so that the locking block 4 will not tilt when rotating, making the installation of the locking block 4 simpler. The locking block 4 will be installed at the position in contact with the surface of the limiting block 2. In this way, when the transmission rod 3 moves the locking block 4, the locking block 4 will move the limiting block 2.

[0029] The upper surface of the transmission rod 3 is connected to a positioning plate 14, and the two ends of the support rod 10 are connected to blocking blocks 15. The transmission rod 3 will fix the position of the positioning plate 14. When the transmission rod 3 moves, it will move the positioning plate 14 with it. The support rod 10 will fix the position of the blocking blocks 15. When the transmission rod 3 moves, it will move the blocking blocks 15 with it. The blocking blocks 15 cannot pass through the blocking blocks 9.

[0030] The outer surface of the blocking block 15 is slidably connected to the inside of the transmission rod 3, and the outer surface of the transmission block 8 is slidably connected to the inside of the transmission rod 3. The transmission rod 3 restricts the direction in which the blocking block 15 can move, so that the position of the blocking block 15 will not deviate. The transmission rod 3 restricts the direction in which the transmission block 8 can move, so as to avoid the position of the transmission block 8 from deviating.

[0031] The upper surface of the air-blocking block 6 contacts the bottom surface of the transmission block 8. The support rod 10 has a vent hole 16 inside. The air-blocking block 6 restricts the direction in which the transmission block 8 can move, thereby preventing the position of the transmission block 8 from deviating. After the support rod 10 is heated, the hot gas of the support rod 10 can be ejected from the vent hole 16.

[0032] A spring 17 is connected to the bottom surface of the positioning plate 14. The end of the spring 17 away from the positioning plate 14 is connected to the upper surface of the transmission block 8. The positioning plate 14 restricts the position of the spring 17 and provides thrust to the transmission block 8 through the spring 17, so that the transmission block 8 can be blocked at the airtight plug 7.

[0033] The airtight plug 7 in this application is a common device in the prior art, and its model or internal structure will not be described in detail here.

[0034] When using this invention, it is first necessary to determine where the copper wire needs to be bent. Then, the user needs to rotate the torsion block 12 at another location. The rotation of the torsion block 12 will cause the connecting rod 11 to rotate with the locking block 4, allowing the locking block 4 to disengage from the transmission rod 3. Then, the transmission rod 3 is pulled out from the limiting block 2. The user then needs to install the copper wire in the outer shell 1 and weld it. The high temperature of the welding will cause the gas inside the support rod 10 to expand. Some of the expanded gas will push open the airtight plug 7 and be discharged from the vent 5. After welding, the spring 17 will push the transmission block 8 to block the airtight plug 7. At the same time, the temperature inside the support rod 10 will decrease, and the air pressure will cause the transmission rod 3 to move with the locking block 4. The movement of the locking block 4 will cause the limiting block 2 to bend with the outer shell 1.
