Description

Technical Field

[0001] The invention relates to the technical field of busbar clamps, in particular to a portable busbar clamp. Background Art

[0002] With the rapid development of urban construction, the requirements for power supply reliability are getting higher and higher. The frequency of use of various operating vehicles such as mobile box transformers and emergency power generation vehicles has greatly increased. The connection tool busbar clamp is often used when the low-voltage side of the box transformer and the power generation vehicle is connected to the busbar at the user end. However, with the frequency of use of the busbar clamp, the clamp teeth of the busbar clamp are more likely to wear or be damaged. If the clamp teeth are found to be severely worn or loose, they should be replaced in time. Of course, incorrect operation methods, such as excessive force or wrong angles, may also cause the clamp teeth to wear faster.

[0003] At present, the current collectors in the existing technologies on the market still have certain technical limitations in actual use. For example, the installation methods of the traditional current collector teeth mainly include two forms. One is to directly buckle the clamping teeth contact pieces of the current collector teeth on the opposite side of the fixed clamp head or the movable clamp head through the built-in bent elastic buckle piece. Although this method is convenient to install during actual operation, the clamping jaws of the fixed clamp head and the movable clamp head must be adjusted to the maximum when replacing and disassembling, and then the clamping jaws must be lifted up along the elastic buckle piece with a flat-blade screwdriver and then removed along the horizontal position of the clamping jaws. If the force is not properly applied during this process, it is easy to cause damage to the buckling point, affecting the secondary installation and use. The other is to directly fix the clamping teeth contact pieces on the opposite side of the fixed clamp head or the movable clamp head through screws and nuts. Although this method has an enhanced fixing effect, it is also necessary to adjust the clamping jaws of the fixed clamp head and the movable clamp head to the maximum during disassembly, and then use the disassembly tool to remove the clamping teeth contact pieces. The above two installation methods are still not convenient enough in actual operation, and are not convenient for technicians to operate and use. Summary of the invention

Its basic principle structure is the existing technology, and its further principle overview is consistent with the principle of an adjustable busbar clamp disclosed in the Chinese patent with publication number CN212908472U, so it will not be repeated here. In addition, the locking mechanism 7 and the linkage mechanism 20 on the directional clamp 5 in the technical solution are consistent with the structural conditions on the movable clamp 6, and the effect of replacing the clamping tooth contact piece 8 is the same;

[0033] One side of the clamping tooth contact piece 8 is laterally symmetrically fixedly connected with a horizontal tooth row 803, and the opposite side of the horizontal tooth row 803 is symmetrically fixedly connected with a vertical tooth row 802.

[0034] The locking mechanism 7 includes a mounting shell 701, one end of the mounting shell 701 is inserted into the inner side of the assembly groove 18, a push plate 702 is slidably connected to the inner side of the mounting shell 701, a receiving groove 704 is provided on the inner side of the mounting shell 701, a first spring 705 is provided on the opposite side of the receiving groove 704 and the push plate 702, an insulating column 703 is symmetrically fixedly installed on the side of the push plate 702 facing the receiving groove 704, one end of the insulating column 703 slides through the receiving groove 704 and the through hole 19 and is plugged into the slot 14, a movable ejector rod 706 is fixedly installed on the other side of the push plate 702 away from the first spring 705, and the movable ejector rod 706 is fixedly installed on the inner side of the other end of the push plate 702 away from the first spring 705 The spherical block 707 is connected, and the unlocking plate 15 and the spherical block 707 are movably connected. During use, when the unlocking plate 15 and the linkage mechanism 20 are in a separated state, the first spring 705 in the mounting shell 701 is in a natural reset state, and the first spring 705 pushes the push plate 702 to slide in the mounting shell 701 toward the unlocking plate 15. At the same time, the end of the insulating clamping column 703 connected to the other side of the push plate 702 retracts in the through hole 19 and separates from the connecting block 13 on the clamping tooth contact piece 8. At this time, the clamping tooth contact piece 8 on the conductor seat 9 can be directly pulled out from the front and replaced. Then, after the new clamping tooth contact piece 8 is inserted into the conductor seat 9, it is only necessary to press the unlocking plate 15 is flipped at the locking groove 16, so that the unlocking plate 15 contacts the spherical block 707 of the movable top rod 706 extending from the push plate 702, and the unlocking plate 15 is squeezed along the arc surface of the spherical block 707, so that the first spring 705 is compressed into the receiving groove 704, until the unlocking plate 15 is fixed by the linkage mechanism 20, and the top plate pushes the push plate 702 in the mounting shell 701 to slide, so that the connected insulating clamping column 703 extends out of the through hole 19 to the connecting block 13 of the clamping tooth contact piece 8 to be fixed; in the natural state of the first spring 705, the insulating clamping column 703 is extended into the through hole 19, and when the unlocking plate 15 is in the limiting state of the movable top rod 706 Under the present invention, after the first spring 705 is compressed, the insulating clamp 703 is inserted into the slot 14 through the through hole 19, and during the disassembly process of the clamping tooth contact piece 8, there is no need to adjust the directional clamp 5 and the movable clamp 6 to the maximum, and rapid disassembly and assembly can be achieved along the insertion direction of the connecting groove 10.

When the unlocking plate 15 is pressed into the locking groove 16, it contacts the locking block 207 extending inside. At the same time, the unlocking plate 15 is squeezed and slid along the inclined surface of the locking block 207. The locking block 207 slides in the side groove 202 at the operating groove 201 through the assembly block 204 connected by the push block 205. At the same time, the assembly The second spring 203 in the side groove 202 of the block 204 is compressed. When the unlocking plate 15 is placed in the locking groove 16, and the locking groove 17 at one end of the unlocking plate 15 away from the rotating part and the locking block 207 at the locking groove 16 are snapped into the corresponding end, the second spring 203 pushes the push block 205 connected to the assembly block 204 to move by resetting, and makes the locking block 207 at the push block 205 snap into the locking groove 17 to fix it. Conversely, when it is necessary to replace the clamping tooth contact piece 8, it only needs to be replaced by using the operation After the pull ring 206 on the push block 205 at the groove 201 is pulled, the locking block 207 on the push block 205 is separated from the locking groove 17 of the clamping tooth contact piece 8, and the unlocking plate 15 automatically lifts the unlocking plate 15 when the locked mechanism is in the reset state; this structure can effectively avoid accidental contact in an unintentional state during use by arranging the key parts of the operating linkage mechanism 20, such as the push block 205 and the pull ring 206, in the operating groove 201, thereby ensuring the safety and stability of the use of the clamping tooth contact piece 8.

At this time, the clamping tooth contact piece 8 on the conductor seat 9 can be directly pulled out from the front and replaced, and then the new clamping tooth contact piece 8 can be inserted into the conductor seat 9, it is only necessary to press the unlocking plate 15 to flip at the locking groove 16, so that the unlocking plate 15 contacts the spherical block 707 of the movable push rod 706 extending from the push plate 702, and the unlocking plate 15 is squeezed along the arc surface of the spherical block 707, so that the first spring 705 is compressed into the receiving groove 704, until the unlocking plate 15 is fixed by the linkage mechanism 20, and the top plate pushes the push plate 702 in the mounting shell 701 to slide, so that the connected insulating clamping column 703 extends out of the through hole 19 to the connection block 13 of the clamping tooth contact piece 8, and it can be fixed;

[0042] When the clamping tooth contact piece 8 is fixed, the unlocking plate 15 pressed down needs to be fixed. When the unlocking plate 15 is pressed into the locking groove 16, it contacts the internally protruding positioning block 207. At the same time, the unlocking plate 15 is squeezed and slid along the inclined surface of the positioning block 207. The positioning block 207 slides in the side groove 202 at the operating groove 201 through the assembly block 204 connected by the push block 205. At the same time, the assembly block 204 compresses the second spring 203 in the side groove 202. When the unlocking plate 15 is placed in the locking groove 16, the positioning groove 17 at one end of the unlocking plate 15 away from the rotating part and the positioning block 20 at the locking groove 16 are After the end portions 7 are correspondingly engaged, the second spring 203 moves the push block 205 connected to the assembly block 204 by resetting, and causes the locking block 207 at the push block 205 to be locked in the locking groove 17 to fix it. Conversely, when the clamping tooth contact piece 8 needs to be replaced, it is only necessary to pull the pull ring 206 on the push block 205 at the operating groove 201 to separate the locking block 207 on the push block 205 from the locking groove 17 of the clamping tooth contact piece 8. The unlocking plate 15 automatically lifts up the unlocking plate 15 in the reset state of the locked mechanism, so that the clamping tooth contact piece 8 can be easily taken out for replacement.
