Description

Technical Field

[0001] The utility model relates to a quick installation buckle for a compact busbar trunking, belonging to the technical field of busbar trunking installation fittings. Background Technique

[0002] The enclosed busbar trunking is applicable to the AC three-phase four-wire and three-phase five-wire systems. The plug-in interfaces of the enclosed busbar trunking are set flexibly and conveniently, and a large number of sockets can be set, with strong versatility. When adjusting the position of the electrical equipment, there is no need to change the power supply system. The rear buckle is designed and installed on the back of the busbar trunking, which can effectively fix and stabilize the busbar trunking in the installation position. This design ensures that the busbar trunking will not shift or swing due to external force or vibration, thus ensuring the stability and reliability of the electrical equipment connection.

[0003] A busbar trunking vertical installation anti-slip buckle device with the Chinese patent number CN211556790U includes a support plate and a bottom plate. A groove is opened at the top of the bottom plate, which solves the problem that the existing anti-slip buckle device is not convenient for people to use. When people use the anti-slip buckle device, they can fix the busbar trunking and prevent the busbar trunking from sliding, which is convenient for people to use.

[0004] During the installation process of the quick installation buckle for the compact busbar trunking, the screw is used in cooperation with the strip groove for installation, which can facilitate the adjustment of the installation position of the screw. However, the open state of the strip groove also makes it more vulnerable to mechanical damage, such as collision or abrasion, further reducing its functionality. Therefore, it is necessary to design a quick installation buckle for the compact busbar trunking with a shielding function to solve the above problems.

[0005] Therefore, a quick installation buckle for the compact busbar trunking is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a quick installation buckle for a compact busbar trunking to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: A quick installation buckle for a compact busbar trunking includes a compact busbar trunking plate. An L-shaped connecting cross plate is arranged below the front end of the compact busbar trunking plate. Strip-shaped notch openings are opened on both the left and right sides of the vertical surface of the L-shaped connecting cross plate. Corrugated connecting pieces are installed on both the left and right inner walls of the corrugated connecting piece. One end of the two corrugated connecting pieces close to each other is fixedly connected with a follower inner plate. The follower inner plate slides left and right in the strip-shaped notch opening. A first inner hole is opened at the inner end of the follower inner plate. A threaded cross bar is installed at the inner end of the first inner hole. The rear end of the threaded cross bar is connected with a U-shaped rear buckle. One end of the U-shaped rear buckle close to the compact busbar trunking plate is fixedly connected with a clamping vertical rod.

[0008] Further preferably, the two strip-shaped notches are symmetrically arranged, and the two U-shaped rear buckles are respectively located on the left and right sides of the compact busbar groove plate.

[0009] Further preferably, side ridges are provided at both the left and right ends of the compact busbar groove plate, and the clamping vertical rod is engaged with the side ridges.

[0010] Further preferably, a threaded nut sleeve is installed at the outer end of the threaded cross bar, and a locking washer is provided between the threaded nut sleeve and the first inner hole.

[0011] Further preferably, the locking washer is sleeved on the outer side of the threaded cross bar, and a through hole communicating with the first inner hole is provided in the middle of the U-shaped rear buckle.

[0012] Further preferably, the threaded cross bar passes through the first inner hole and the locking washer inside and outside, and both the threaded nut sleeve and the locking washer are located at the rear side of the U-shaped rear buckle.

[0013] Further preferably, an anti-slip cushion layer is fixedly connected to the side of the U-shaped rear buckle and the clamping vertical rod close to the compact busbar groove plate, and the anti-slip cushion layer is in contact with the outer side wall of the compact busbar groove plate.

[0014] Further preferably, a pair of mounting transverse holes are provided on the upper side of the horizontal plane of the L-shaped connecting transverse plate, and two support screw members are externally connected to the two mounting transverse holes.

[0015] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0016] 1. When the threaded cross bar penetrates through the strip-shaped notch in this solution, a follower inner plate convenient for sliding can be arranged in the strip-shaped notch. The corrugated connecting pieces at both ends of the follower inner plate can be adjusted according to the actual position of the follower inner plate. When the threaded cross bar penetrates through the first inner hole, other areas in the strip-shaped notch can be kept blocked, avoiding the risk of mechanical damage caused by being always exposed, making the service life of the strip-shaped notch longer, effectively extending the adaptation time limit with the threaded cross bar, and making the adjustment flexible and convenient during use.

[0017] 2. At the same time, when the threaded cross bar connects the U-shaped rear buckle, a locking washer can be arranged between the threaded nut sleeve and the threaded cross bar. The locking washer can effectively improve the installation connection tightness of the threaded cross bar, making it not easy to loosen due to the vibration of the compact busbar groove plate. At the same time, an anti-slip cushion layer is provided on the side of the U-shaped rear buckle and the clamping vertical rod close to the compact busbar groove plate. The anti-slip cushion layer can increase the friction surface of the connection surface between the U-shaped rear buckle and the clamping vertical rod, making part of the vibration force absorbed, and making the shock absorption and stability ability of the U-shaped rear buckle stronger.

[0028] Embodiment 1

[0029] AsFigures 1-5 As shown in Figures 1-5 , an embodiment of the present utility model provides a quick-installation buckle for a compact busbar trunking, which includes a compact busbar trunking board 1. Below the front end of the compact busbar trunking board 1, there is an L-shaped connecting cross board 2. Strip-shaped notches 3 are opened on both the left and right sides of the vertical surface of the L-shaped connecting cross board 2. Corrugated connecting pieces 4 are installed on both the left and right inner walls of the corrugated connecting pieces 4. One end of the two corrugated connecting pieces 4 close to each other is fixedly connected with a follower inner plate 5. The follower inner plate 5 slides left and right in the strip-shaped notch 3. A first inner hole 6 is opened at the inner end of the follower inner plate 5. A threaded cross bar 7 is installed at the inner end of the first inner hole 6. The rear end of the threaded cross bar 7 is connected with a U-shaped rear buckle 8. One end of the U-shaped rear buckle 8 close to the compact busbar trunking board 1 is fixedly connected with a clamping vertical bar 9.

[0030] Since the two strip-shaped notches 3 are symmetrically arranged, the two U-shaped rear buckles 8 are respectively located on the left and right sides of the compact busbar trunking board 1. Side convex strips 12 are provided at both the left and right ends of the compact busbar trunking board 1. The clamping vertical bar 9 is engaged with the side convex strip 12. A threaded nut sleeve 10 is installed at the outer end of the threaded cross bar 7. The threaded nut sleeve 10 and the locking washer 11 are both located at the rear side of the U-shaped rear buckle 8. A pair of installation cross holes 16 are opened on the upper side of the horizontal plane of the L-shaped connecting cross board 2.
