Description

Technical Field

[0001] The utility model relates to the technical field of mounting accessories for a stand distribution box, in particular to an elbow for an inlet and outlet bushing of a stand distribution box. Background Art

[0002] The bench distribution box needs to be installed outdoors due to usage requirements, and some of the wires connected to the distribution box need to be stretched outside the distribution box for connection to other equipment. Therefore, a sleeve elbow is used at the pull-out part of the distribution box to protect this part of the wires.

[0003] Currently available sleeve elbows are generally divided into two categories: one that uses two 45-degree elbows to create a 90-degree bend, and the other a one-piece 90-degree elbow. Both types of sleeve elbows are designed for DN50 PVC pipes used for industrial or water supply applications, have a uniform outer diameter of 50mm, and are designed for socket-and-spigot installation. However, in practice, the appearance of the same type of industrial or water supply PVC pipe is not significantly different from that of PVC cable conduit, making it easy to purchase multiple materials with different installation parameters. This makes it impossible to directly use the socket-and-spigot installation method for DN50 PVC cable conduit, resulting in low installation efficiency and considerable complexity. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an elbow for an incoming and outgoing line bushing of a stand distribution box.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A bushing elbow for incoming and outgoing lines of a stand distribution box comprises a bushing elbow body and a sealing assembly kit provided on two connecting ends of the bushing elbow body, wherein external pipelines are socket-mounted on the bushing elbow body through the sealing assembly kit.

[0007] As described above, the inlet and outlet bushing elbow of the bench distribution box can be provided with a sealing ring which can be detachably connected on the inner wall of the sealing assembly kit.

[0008] As described above, in the inlet and outlet bushing elbow of a stand distribution box, the sealing ring includes a plurality of sealing rings stacked and bonded from the outside to the inside, and the inner diameters of the plurality of sealing rings gradually decrease from the outside to the inside.

[0009] As described above, in the elbow for the incoming and outgoing line bushings of a stand distribution box, the number of the sealing rings is 3, wherein the inner diameters of the plurality of sealing rings are φ58mm, φ57mm and φ50mm respectively from the outside to the inside.

[0010] As described above, the bushing elbow for incoming and outgoing lines of a stand distribution box comprises a bushing elbow body comprising two symmetrically arranged bushing bends, which are relatively connected to form the bushing elbow body.

[0011] In the above-mentioned inlet and outlet bushing elbow of a stand distribution box, the sealing assembly kit and the sealing ring are made of rubber.

[0012] As described above, the bushing elbow for the incoming and outgoing wires of a rack distribution box is made of PVC pipe.

[0013] As described above, in the inlet and outlet bushing elbow of a stand distribution box, the sealing assembly kit is detachably connected to the two connecting ends of the bushing elbow body.

[0014] The beneficial effects of the present invention are as follows: the present invention has a simple structure, and a sealing assembly kit is provided on the sleeve elbow body. When the sleeve elbow body matches the size of the external pipeline, the sealing assembly kit can be directly disassembled and directly installed with the sleeve elbow body by socket connection. If they do not match, the sealing assembly kit that matches the size of the external pipeline can be replaced and adjusted to the two connecting ends of the sleeve elbow body, and then the sealing assembly kit can be installed with the external pipeline by socket connection. The construction efficiency is high, the applicability is strong, and it is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
