Description

Technical Field

[0001] The utility model relates to the field of tubular busbar bridge structures, and more specifically to a tubular busbar bridge reinforcement connection structure. Background Art

[0002] The tubular busbar is a busbar product that uses copper tubes or aluminum alloy tubes as conductors and is insulated externally. The tubular busbar needs to be installed using a bracket to form a tubular busbar bridge structure.

[0003] Affected by the changes in external ambient temperature and the voltage load of the tubular busbar, a certain temperature change will occur inside the tubular busbar, which will cause the tubular busbar to undergo hot and cold deformation. However, the existing connection between the tubular busbar and the bracket is usually in the form of a fixed connection. Although such a connection form can make the tubular busbar connection relatively stable in a short period of time, it is easily affected by the changes in the hot and cold deformation of the tubular busbar over a long period of time, causing pulling deformation at the connection, and even metal fatigue and fracture at the connection, which is not conducive to the stability of the tubular busbar bridge connection structure. Therefore, we propose a tubular busbar bridge reinforced connection structure to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a tubular busbar bridge reinforced connection structure, which utilizes the tubular busbar connection structure to install the corresponding two sections of tubular busbar bodies on a base bracket. Since a group of slides inside the tubular busbar connection structure are slidably connected on the slide rod and supported by an extrusion spring, a certain redundant space can be provided for the tubular busbar body under hot and cold deformation, thereby reducing the direct pulling effect on the connection of the tubular busbar body and reducing the occurrence of metal fatigue and fracture at the connection, which is beneficial to improving the stability of the tubular busbar bridge connection structure.

[0006] 2. Technical solution

[0009] Furthermore, a compression spring is sleeved on the screw one and the screw two at the connection point between the screw one and the screw two and one of the contact sheets.

[0010] Furthermore, both ends of a group of the sliding rods are provided with external thread structures, and both ends of a group of the sliding rods are threadedly connected with adjusting nuts, and the sliding rods located between the adjusting nuts and the corresponding sliding seats are sleeved with support springs, and both ends of the support springs are respectively in contact with one side of the adjusting nut and one side of the sliding seat.

[0011] Furthermore, an insulating sleeve is sleeved on the slide rod at the connection between the slide seat and the corresponding slide rod, and an insulating gasket is fixedly adhered to one side of the slide seat at the connection between the support spring and one side of the corresponding slide seat.

[0012] Furthermore, a plurality of expansion bolt holes are equidistantly provided on the base bracket.

[0013] 3. Beneficial effects

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 A tubular busbar bridge reinforcement connection structure comprises a base support 1, on which a plurality of tubular busbar connection structures 2 with the same structure are arranged, the tubular busbar connection structure 2 comprises a group of sliding rods 3 fixedly welded on the base support 1, and a group of sliding seats 4 are slidably connected between the group of sliding rods 3, a group of sliding seats 4 are all fixedly welded with connecting ends 5 on the tops, and a group of connecting ends 5 are all fixedly installed with tubular busbar bodies 6 by screws, one of the connecting ends 5 is provided with a strip sliding hole 501, and the other connecting end 5 is provided with a round hole 502, and contact pieces 7 are arranged on both sides of a group of connecting ends 5, one end of the two contact pieces 7 is rotatably connected to both sides of the round hole 502 by screw one 8, and the other end of the two contact pieces 7 is slidably connected to both sides of the strip sliding hole 501 by screw two 9.

[0025] The principle of using this tubular busbar bridge reinforced connection structure is:

[0026] First, the base bracket 1 is installed on the wall through the expansion bolt hole 101 on the base bracket 1, and then the corresponding tubular busbar body 6 is connected through the connecting end 5. When the tubular busbar body 6 is affected by the external ambient temperature change or the internal voltage load causes the temperature of the tubular busbar body 6 to change, the tubular busbar body 6 will be deformed, that is, the expansion deformation due to heating and the contraction deformation due to cooling. At this time, at the connection between the tubular busbar body 6 and the corresponding slide rod 3 through the slide seat 4, the slide seat 4 will move on the slide rod 3 to supplement the amount of deformation of the tubular busbar body 6, thereby avoiding the risk of metal fatigue and fracture at the connection caused by rigid connection.

[0027] Embodiment 2:

[0028] In view of the above embodiment 1, for further description, refer to Figure 3 and Figure 4 , the screws 1 8 and the screws 2 9 at the connection between the screws 1 8 and the screws 2 9 and one of the contact pieces 7 are both sleeved with an extrusion spring 10, both ends of a group of slide rods 3 are provided with external thread structures, and both ends of a group of slide rods 3 are threadedly connected with adjusting nuts 11, and the slide rods 3 located between the adjusting nuts 11 and the corresponding slide seats 4 are sleeved with support springs 12, and the two ends of the support springs 12 are respectively in contact with one side of the adjusting nuts 11 and one side of the slide seat 4, and the slide rods 3 located at the connection between the slide seat 4 and the corresponding slide rod 3 are sleeved with an insulating sleeve, and an insulating gasket is fixedly attached to one side of the slide seat 4 located at the connection between the support spring 12 and one side of the corresponding slide seat 4, and a plurality of expansion bolt holes 101 are equidistantly provided on the base bracket 1.

[0029] The opening of the strip-shaped sliding hole 501 on one of the connection ends 5 can make one end of the contact piece 7 connected thereto active, providing space for the movement of the slide 4 when the tubular busbar body 6 is deformed, and the setting of the support spring 12 can support the slide 4 without interfering with the movement of the slide 4. The setting of the insulating sleeve and the insulating gasket can insulate and isolate the connection to prevent electricity from being conducted to the base bracket 1.

[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
