Description

Technical Field

[0002] The low-voltage tubular busbar needs to be connected to a low-voltage tubular busbar connecting device during use. The low-voltage tubular busbar connecting device currently on the market usually directly collects the low-voltage tubular busbars and fixes them using the connecting device to avoid the low-voltage tubular busbars from becoming messy. The fixed low-voltage tubular busbars are fixed to the surface or bottom of the wall through the connecting device to avoid the use of the low-voltage tubular busbars affecting the normal work of the operators.

[0003] A Chinese patent with publication number CN218449372U was searched and disclosed a low-voltage tubular busbar connection device.

[0004] The utility model includes an upper clamp and a lower clamp. The upper clamp is rotatably connected to the lower clamp by a hinge. Both sides of the upper clamp are detachably connected with telescopic rods. The telescopic rods are distributed in a group. The output end of the telescopic rod is fixed to the upper support. Both sides of the lower clamp are also detachably connected with telescopic rods. The telescopic rod on the lower clamp is fixed to the lower support. The lower support and the upper support are distributed in the middle of the upper clamp and the lower clamp. The low-voltage tubular busbar connection device solves the problem that some existing busbar connection devices are inconvenient for users to adjust different support positions according to the weight of the busbar after the busbar is stored by setting the upper clamp to be rotatably connected to the lower clamp, the upper clamp and the lower clamp are connected with telescopic rods on both sides, the telescopic rod on the upper clamp is connected to the upper support, and the telescopic rod on the lower clamp is connected to the lower support.

[0005] However, the patent still has the following problems: the device can limit multiple busbars by hinged connection between the upper clamping part and the lower clamping part, but when a single busbar needs to be taken out, the operator needs to twist out the fixing bolt and then open the two clamping parts. This not only requires the use of tools to open the device, but also causes multiple busbars to fall out from between the two clamping parts at the same time after the device is opened, which is easy to cause scattering, bringing certain inconveniences to the normal use of the device.

DETAILED DESCRIPTION

[0023] See also Figure 1-5 , a low-voltage tubular busbar connection device, comprising a connection mechanism 1, a limiting mechanism 2 is arranged on the top of the connection mechanism 1;

[0024] The connection mechanism 1 is used to connect the device to a wall, and the limiting mechanism 2 enables multiple busbars to obtain a limiting effect and can be taken out more conveniently.

[0025] The limiting mechanism 2 includes a bottom shell 201 and a top shell 202, the bottom shell 201 and the top shell 202 are hinged, a plurality of first telescopic rods 203 are fixed on the front and rear sides of the bottom shell 201 and the top shell 202, a U-shaped frame 204 is fixed on the surface of the first telescopic rod 203, the inner walls of the bottom shell 201 and the top shell 202 are provided with inner grooves, the surface of the inner groove is rotatably connected with a first roller 205, the surface of the U-shaped frame 204 is rotatably connected with a second roller 206, a limiting block 207 is fixed on one side of the top shell 202, a limiting shell 208 is provided on one side of the bottom shell 201, a first spring 209 is fixed on the surface of the limiting shell 208, and a positioning block 210 is fixed on the surface of the first spring 209;

[0026] After the busbar is placed in the bottom shell 201, the busbar will contact the surface of the first roller 205. At this time, the top shell 202 is rotated downward and the positioning block 210 is pulled so that the limit block 207 can be located below the positioning block 210, so that the top shell 202 and the bottom shell 201 can limit the busbar. When the busbar is pulled or affected by other activities, the surface of the busbar will generate friction with the surface of the first roller 205, and the first roller 205 can rotate to reduce friction, and at the same time, the second roller 206 at the outer support part of the busbar can also The upper and lower shells 201 and 202 can rotate together, so that the surface of the busbar is not easily worn when it is active, thereby increasing the service life of the busbar. When a single busbar needs to be taken out, the positioning block 210 is pulled to compress the first spring 209. At this time, the limit on the top of the limit block 207 will be released, allowing the operator to rotate the top shell 202 upward, so that the inner busbar can be taken out from the bottom shell 201 and the top shell 202, thereby realizing the separate removal of the busbar, and no tools are required when taking out the busbar, making it more convenient to inspect and debug the busbar.

[0027] Further, the connection mechanism 1 includes a mounting shell 101, a connecting plate 102 is fixed to the surface of the mounting shell 101, a mounting plate 103 is slidably connected to the surface of the mounting shell 101, and the top of the mounting plate 103 is fixedly connected to the bottom shell 201 and the limiting shell 208;

[0028] The connecting plate 102 is used to be fixed to the wall by bolts, and the mounting shell 101 can be combined and disassembled with the mounting plate 103, so that when multiple bottom shells 201 need collective maintenance, the operator can directly pull the mounting plate 103 to remove the mounting plate 103 and the mounting shell 101 without removing the connecting plate 102 from the wall, making it more convenient to inspect and maintain the device.

[0029] Furthermore, a second spring 211 is fixed to the bottom of the inner wall of the limiting shell 208, and an ejection plate 212 is fixed to the top of the second spring 211;

[0030] When the limit block 207 is located at the bottom of the positioning block 210, the limit block 207 will contact the ejection plate 212 to compress the second spring 211. When the positioning block 210 stops blocking the limit block 207, the second spring 211 can rebound, so that the top shell 202 can automatically open upward, making it more convenient to take the busbar.

[0031] Furthermore, the limit block 207 is arranged in a wedge-shaped structure;

[0032] The limit block 207 is set to be wedge-shaped, so that when its inclined surface contacts the top of the positioning block 210, the inclined surface of the limit block 207 can push the positioning block 210 to move toward the first spring 209, so that when the top shell 202 and the bottom shell 201 are closed, the limit block 207 can automatically enter under the positioning block 210, thereby improving convenience during use.

[0033] Furthermore, a second telescopic rod 213 is disposed inside the first spring 209, one end of the second telescopic rod 213 is fixedly connected to the surface of the positioning block 210, and the other end of the second telescopic rod 213 is fixedly connected to the surface of the limiting shell 208;

[0034] When the positioning block 210 moves, the second telescopic rod 213 can be telescoped, so that the positioning block 210 can be guided to prevent the positioning block 210 from moving up and down when the limiting block 207 pushes the positioning block 210 to move.

[0035] Furthermore, the mounting plate 103 is arranged in a T-shaped structure, and a taking groove 104 is provided on the surface of the mounting plate 103;

[0036] The T-shaped structure can increase the friction between the mounting plate 103 and the inner wall of the mounting shell 101, making it difficult for the mounting plate 103 to slide on the inner wall of the mounting shell 101 by itself, and also ensures that the mounting plate 103 will not detach from the inside of the mounting shell 101 by moving upward. The setting of the taking groove 104 makes it easier for the operator to pull the mounting plate 103.

[0037] Furthermore, a plurality of anti-slip grooves are provided on the top of the positioning block 210;

[0038] The provision of the anti-skid groove enables the operator's hand to contact the top of the positioning block 210 , and the anti-skid groove can provide more friction, so that the positioning block 210 can be moved more easily.
