Description

Technical Field

[0001] This utility model relates to the field of busbar trunking technology, and in particular to a sealing structure for a busbar trunking connector box. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute a large amount of power to various components of a distributed system. In indoor low-voltage power transmission trunk line projects, it has increasingly replaced wires and cables. With the rapid development of urban modernization in my country and the continuous improvement of people's living standards, the country's requirements for electricity use and personal safety are also getting higher and higher. Busbar trunking is widely used in power transmission trunk lines. Plug-in boxes need to be installed on the busbar trunking to distribute power.

[0003] Existing busbar junction boxes require sealing before the busbar trunking is put into use to facilitate transportation and storage, preventing dust and water from entering and damaging the busbar trunking. However, the sealing structure of existing busbar junction boxes, relying on bolt fastening during transportation or storage in humid or dusty environments, is susceptible to damage or failure due to vibration or thermal expansion and contraction.

[0004] Therefore, it is urgent to research and develop a sealing structure for busbar trunking junction boxes to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a busbar trunking plug box sealing structure, which can improve the sealing effect of the plug box under vibration or thermal expansion and contraction.

[0006] To achieve the above objectives, this utility model provides a busbar trunking plug-in box sealing structure, the specific implementation of which is as follows:

[0007] A busbar trunking junction box sealing structure includes a base and a flip cover. A connecting protrusion is provided at any end of the top surface of the base, and a connecting post is provided at the bottom of the flip cover corresponding to the connecting protrusion. The connecting post is embedded in the connecting protrusion, and the flip cover is rotatably connected to the base along the circumferential direction of the connecting post.

[0008] A fastener is provided on the top end of the base opposite to the connecting protrusion, and a hook is provided on the bottom of the flip cover at a position corresponding to the fastener. The hook engages with the fastener.

[0009] A sealing strip is provided on the outer periphery of the top of the base, and the top of the sealing strip protrudes from the top of the base and abuts against the bottom of the flip cover.

[0010] This utility model discloses a sealing structure for a busbar duct connector box. Compared with the prior art, it features a sealing strip along the outer periphery of the top of the base. The top of the sealing strip protrudes from the top of the base and abuts against the bottom of the flip cover. Combined with the snap-fit ​​mechanism of the hooks on the flip cover and the fasteners on the base, the flip cover is stably closed onto the base. Even during transportation or storage, vibration or thermal expansion and contraction occurs, ensuring the flip cover remains closed to the base and the sealing strip at the connection point between the flip cover and the base is maintained due to the snap-fit ​​mechanism of the hooks and fasteners and the abutment between the sealing strip and the flip cover. This improves the sealing effect of the connector box under vibration or thermal expansion and contraction.

[0011] In some embodiments, the flip cover rotates relative to the base to form a first state or a second state, and the connecting post and the connecting protrusion rotate to form a first position and a second position.

[0012] In the first state, the connecting post rotates from the first position of the connecting protrusion to the second position along its own circumferential direction, the flip cover closes on the base, the hook engages with the fastener, and the top of the sealing strip abuts against the bottom of the flip cover to form a sealed state.

[0013] In the second state, the connecting post rotates from the second position of the connecting protrusion to the first position along its own circumferential direction, the hook separates from the fastener, and the flip cover and the base form an opening angle, thus forming an open state.

[0014] By rotating the connecting post on the connecting protrusion between a first position and a second position, the sealing and opening states between the flip cover and the base can be switched, thereby improving ease of use by switching between sealing the bottom of the insert box and opening it for use.

[0015] In some embodiments, the opening angle between the flip cover and the base is 0°-180°.

[0016] By setting the opening angle of the flip cover and base to 0°-180°, the opening range of the flip cover is increased, which facilitates the insertion of the box and the subsequent removal of the flip cover.

[0017] In some embodiments, an annular groove is provided on the top outer periphery of the base, and the sealing strip is partially embedded in the annular groove.

[0018] By setting an annular groove on the top outer periphery of the base, up to a portion of the sealing strip is embedded in the annular groove, thereby improving the connection stability between the sealing strip and the base.

[0019] In some embodiments, an annular protrusion is provided on the bottom outer periphery of the flip cover, and when the flip cover and the base are in a sealed state, the inner peripheral wall of the annular protrusion wraps around the outer peripheral wall of the base.

[0020] By providing an annular protrusion along the bottom outer periphery of the flip cover, the inner peripheral wall of the annular protrusion wraps around the outer peripheral wall of the base when the flip cover and the base are in a sealed state, thereby further improving the connection and sealing effect between the flip cover and the base.

[0021] In some embodiments, an arc-shaped groove is provided on the top of the connecting protrusion, and the connecting post is embedded in the arc-shaped groove.

[0022] By setting an arc-shaped groove on the top of the connecting protrusion, the connecting post is embedded in the arc-shaped groove, ensuring the connection between the connecting post and the connecting protrusion, as well as the relative rotation between the connecting post and the connecting protrusion after connection.

[0023] In some embodiments, the connecting protrusion is a plastic part, and the diameter of the top opening of the arc-shaped groove is smaller than the diameter of the connecting post.

[0024] By setting the connecting protrusion as a plastic part and setting the diameter of the top opening of the arc-shaped groove to be smaller than the diameter of the connecting post, it is ensured that the connecting post can break through the top opening of the arc-shaped groove during installation. After the installation is stable, the top opening can be used to restrict the disconnection of the connecting post, thereby improving the connection stability of the connecting post in the arc-shaped groove.

[0025] In some embodiments, two through slots are provided on the fastener, and a fastening plate is provided directly in the two through slots. The fastening plate has a space that connects the two channels. The hook is embedded in the through slot at the bottom and engages with the fastening plate to fasten into the space of the fastening plate, or it is fastened into the through slot at the top.

[0026] By setting two through slots on the fastener and setting a fastening plate between the two through slots, the fastening plate has a space to conduct the two channels. After the hook is embedded in the through slot at the bottom, it is fastened into the space of the fastening plate or through the space and fastened into the through slot at the top to achieve a snap connection between the flip cover and the base, thereby improving the connection stability and connection convenience.

[0027] In some embodiments, a gripping flange is provided on the end of the flap where the hook is located, the gripping flange extending in a direction away from the flap.

[0028] By providing a gripping protrusion on the end of the flip cover with a hook, and extending the gripping protrusion away from the flip cover, the user experience is improved by gripping the protrusion to make it easier to open the flip cover and the base.

[0029] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0030] By setting a sealing strip on the top outer periphery of the base, the top of the sealing strip protrudes from the top of the base and abuts against the bottom of the flip cover. With the cooperation of the hooks on the flip cover and the snap fasteners on the base, the flip cover can be stably closed on the base. Even if vibration or thermal expansion and contraction occurs during transportation or storage, the snap fasteners and the contact between the sealing strip and the flip cover will always ensure that the flip cover is closed with the base and that the sealing strip seals the connection between the flip cover and the base, thus improving the sealing effect of the plug box under vibration or thermal expansion and contraction.
