Description

Technical Field

[0001] The utility model relates to the technical field of home decoration circuits, in particular to a threaded reducing cross. Background Art

[0002] In the field of home decoration, the specifications of electrical conduits are usually 16 or 20 large tubes, with multiple wires passing through them. Due to the thick diameter of the tube, it is usually necessary to groove when running on the ground or wall, and a suspended ceiling is required to hide the pipe when running on the ceiling. The groove depth is more than 20mm. With the ever-changing decoration style, the minimalist style is chosen by more people, which means fewer and shallower grooves, and trying not to make suspended ceilings, etc. have become people's needs. Single tube and single wire came into being, compressing the tube diameter, reducing the groove depth, and only one wire is passed through a single tube. The docking sockets of multiple small tubes are a certain distance away from the sockets of the large tubes. When pulling the wires, the wires have a deflection angle, there is resistance in pulling the wires, and the cross may fall off during the pulling process. Utility Model Content

[0003] In view of the above problems, the utility model aims to provide a threaded reducing cross, which makes the distance between the small pipe butt socket and the large pipe butt socket closer and reduces the wire pulling resistance.

[0004] The technical problem solved by the utility model can be achieved by adopting the following technical scheme: a threaded reducing four-way, comprising a reducing four-way body and a reducing four-way cover, the reducing four-way body and the reducing four-way cover are connected by threads, the reducing four-way body is hollow, one end of the reducing four-way body is a large tube docking socket, the reducing four-way cover comprises a cover body and a plurality of small tube docking sockets, one side of the cover body is provided with small tube docking sockets, the small tube docking sockets are annularly distributed on one side of the reducing four-way cover, and the other side of the small tube docking sockets is threadedly connected to the reducing four-way body.

[0005] There are three small tube butt sockets, which are annularly distributed on one side of the reducing four-way cover, and the outer tube walls of the three small tube butt sockets are in contact with each other.

[0006] One end of the reducing cross body is provided with an external thread, and one side of the reducing cross cover is provided with an internal thread that matches the reducing cross body. The external thread and the internal thread are screwed together to connect the reducing cross body and the reducing cross cover together.

[0007] The reducing cross body and the reducing cross cover are connected by multi-thread threads.

[0008] The inner diameter of the connection between the reducing cross body and the reducing cross cover gradually increases at one end close to the reducing cross cover.

[0009] The utility model has the following beneficial effects compared with the prior art: The utility model adopts a split design, which is divided into a reducing four-way main body and a reducing four-way cover, facilitating assembly, disassembly, production and manufacturing. 2. The reducing four-way main body and the reducing four-way cover adopt multi-start threads, which can improve the connection strength between the reducing four-way main body and the reducing four-way cover and prevent separation and detachment during the wire pulling process. 3. The small pipe butt joints are annularly distributed. The annular distribution makes the centers of the multi-root small pipe butt joints closer to the large pipe socket, resulting in a smaller deflection angle of the wire during wire pulling and thus less wire pulling resistance.

[0014] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below with reference to specific drawings.

[0015] In the description of the utility model, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end portion", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the utility model.

[0016] Combined with the attached Figures 1 to 3As shown in the figure, this embodiment discloses a threaded reducing cross, which includes a reducing cross body 1 and a reducing cross cover 2. The reducing cross body 1 and the reducing cross cover 2 are connected by threads. The reducing cross body 1 is hollow. One end of the reducing cross body 1 is a large pipe docking socket 11. The reducing cross cover 2 includes a cover body 21 and three small pipe docking sockets 22. One side of the cover body 21 is provided with small pipe docking sockets 22. The three small pipe docking sockets 22 are annularly distributed on one side of the reducing cross cover 2. The outer tube walls of the three small pipe docking sockets 22 are in contact with each other. The other side of the small pipe docking socket 22 is screwed to the reducing cross body 1. The annular distribution of the small pipe docking sockets makes the centers of the small pipe docking sockets 22 closer to the large pipe socket 11. When pulling the wire, the deflection angle of the wire is smaller, and the wire pulling resistance is also smaller.

[0017] One end of the reducing cross body 1 is provided with an external thread 12, and one side of the reducing cross cover 2 is provided with an internal thread 23 that cooperates with the reducing cross body 1. The external thread 12 and the internal thread 23 are screwed together to connect the reducing cross body 1 and the reducing cross cover 2.

[0018] The connection between the reducing cross body 1 and the reducing cross cover 2 has an inner diameter that gradually increases near one end of the reducing cross cover 2. The wire pulling resistance is small, which is beneficial for wire pulling.

[0019] The reducing cross body 1 and the reducing cross cover 2 are connected by multi-start threads. The multi-start threads can improve the connection strength between the reducing cross body 1 and the reducing cross cover 2 and prevent separation and detachment during the wire pulling process. The split design is beneficial for assembly, disassembly, production, and manufacturing.

[0020] The above is only a preferred embodiment of the present invention and does not impose any formal restrictions on the invention. Any simple modification, equivalent change, or decoration made to the above embodiments based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
