Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically relating to a sliding rail type busbar elbow. Background Technology

[0002] Installing elbows is time-consuming and difficult. Rectangular busbars installed inside irregularly shaped copper busbars are prone to issues in ensuring verticality, making it difficult to maintain a 90° angle on the profiles after installation. Gaps exist at the elbow corners after installation, affecting the protection level (especially for Z-shaped elbows). Deviations in the installation height of the busbars delivered to the site can cause the gaps at the elbow corners to widen, exposing the internal insulation components and copper busbars, allowing dust to seep in and affecting performance. Therefore, a sliding rail type busbar elbow needs to be designed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a sliding rail type busbar elbow to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding rail type busbar elbow, comprising a first profile and a second profile, wherein one end surface of the first profile and the second profile are both set as 45-degree surfaces, and the first profile and the second profile are fixed together by welding at the 45-degree surfaces. The first profile includes a base plate and a top plate installed on the upper side of the base plate, and the top plate and the base plate are fixed together by screws. The structure of the second profile is the same as that of the first profile.

[0005] Preferably, a connecting plate is provided on the lower side of the top plate, and a mounting plate is provided on the upper side of the bottom plate. The mounting plate is inserted into the inner side of the connecting plate and fixed with screws.

[0006] Preferably, one end of the first profile and the second profile are provided with screw holes, and the first profile and the second profile are fixed to the busbar body profile by screws and screw holes.

[0007] Preferably, sealant is provided at the connection between the ends of the first and second profiles and the busbar body.

[0008] Preferably, the top plates of the first profile and the bottom plates of the second profile are welded together by a 45-degree inclined surface.

[0009] Preferably, both the top plate and the bottom plate have positioning grooves on their inner sides.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In the case of the elbow profile of this utility model, the L-shaped elbow and Z-shaped elbow of the sliding rail small busbar, the busbar trunking body profile does not need to be cut at a 45° angle during the outer shell sawing. It is only necessary to cut the upper and lower profiles at the corner of the elbow profile at a 45° angle and then weld them.

[0012] 2. During assembly, the copper busbars are inserted into the profiles, eliminating the phenomenon of copper busbars hitting each other at corners and avoiding the gap problem after the original design's outer shell is locked. The upper and lower profiles of the elbows are used to cover the busbars, improving the IP protection level of the busbars and preventing cracking at the elbows and corners caused by manual handling and inconsistent heights during installation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3This utility model provides a technical solution: a sliding rail type busbar trough elbow, including a first profile 1 and a second profile 2. One end surface of the first profile 1 and the second profile 2 are both set as 45-degree surfaces, and the first profile 1 and the second profile 2 are fixed by welding together through the 45-degree surfaces. The first profile 1 includes a base plate 4 and a top plate 3 installed on the upper side of the base plate 4. The top plate 3 and the base plate 4 are fixed by screws. The structure of the second profile 2 is the same as that of the first profile 1. The main body of the busbar profile is installed in the base plate 4 of the first profile 1 and the second profile 2 and fixed by screws. The busbars are connected at the bend. Then the top plate 3 is placed on the base plate 4. A connecting plate 5 is provided on the lower side of the top plate 3, and an installation plate 6 is provided on the upper side of the base plate 4. The installation plate 6 is inserted into the inner side of the connecting plate 5 and fixed by screws. The top plate 3 is placed on the base plate 4. The connecting plate 5 and the installation plate 6 are engaged and fixed by screws.

[0019] Further reading is available. Figures 1 to 3 Both the first profile 1 and the second profile 2 have screw holes at one end, and the first profile 1 and the second profile 2 are fixed to the busbar body profile by screws and screw holes, which facilitates the fixing of the elbow to the main body of the busbar profile during use; the ends of the first profile 1 and the second profile 2 are provided with sealant at the connection with the busbar body to enhance the covering and sealing ability of the elbow; the top plate 3 and the bottom plate 4 of the first profile 1 and the second profile 2 are welded together by a 45-degree inclined surface, which facilitates the fixing of the top plate 3 and the bottom plate 4 into an elbow shape during use, and can fix each other to cover and install the main body of the sliding rail type small busbar profile; the inner sides of the top plate 3 and the bottom plate 4 are both positioning grooves, which facilitates the locking of the main body of the sliding rail type small busbar profile into the inner sides of the top plate 3 and the bottom plate 4 and fixing it with screws during use.

[0020] As can be seen from the above description, this utility model has the following beneficial effects: the L-shaped and Z-shaped elbows of the sliding rail type small busbar are sawn in the outer shell, and the busbar trunking profile does not need to be sawn at a 45° angle. Only the upper and lower profiles at the corner of the elbow profile need to be sawn at a 45° angle and then welded. During the assembly process, the copper busbar is inserted into the profile. The corner of the elbow is adjustable, which eliminates the phenomenon of the copper busbar hitting the corner hard. It avoids the problem of gaps after the outer shell is locked in the original design. The upper and lower profiles of the elbow are used to cover the busbar, which improves the IP protection level of the busbar. It also eliminates the phenomenon of cracking at the corner of the elbow caused by manual handling and inconsistent height during installation.

[0021] The working principle and usage process of this utility model are as follows: When in use, the main body of the busbar profile is installed in the base plate 4 of the first profile 1 and the second profile 2 and fixed with screws. The busbars are connected at the bends. Then, the top plate 3 is placed on the base plate 4 and connected by the connecting plate 5 and the mounting plate 6 and fixed with screws. Then, the top plate 3 is fixed on the main body of the busbar profile with screws to complete the covering of the busbar profile. Glue is applied to the ends of the first profile 1 and the second profile 2.
