Description

Technical Field

[0001] This invention relates to the field of cable tray technology, and in particular to a tee connector for cable trays. Background Technology

[0002] Cable trays are classified into various structures such as trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays, and consist of supports, brackets, and installation accessories. T-joints are sometimes used to assist in the installation of cable trays.

[0003] However, most existing cable tray tee connectors are one-piece designs, which cannot adjust the orientation of the outgoing end according to the user's needs for laying cable trays, thus having certain limitations. Therefore, we propose a cable tray tee connector. Summary of the Invention

[0004] This invention provides a tee connector for cable trays, which solves the technical problems mentioned in the background section of the prior art.

[0005] The present invention provides the following solution to the above-mentioned technical problems: It includes a tee connector body, with through slots on both sides of the three outlet ends of the tee connector body. Each of the three outlet ends of the tee connector body is provided with an outlet frame. Two rotating adjustment plates, each slidably connected to the through slots, are fixedly connected to one end of each outlet frame. A rotating column, penetrating the tee connector body and rotatably connected to the penetrating portion via a bearing, is fixedly connected to one side of the rotating column at the upper end of the tee connector body. A positioning mechanism is provided on one side of the rotating column. A clamping mechanism is provided inside each outlet frame.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the clamping mechanism includes a limiting pressure plate that is slidably connected to the inside of the corresponding wire outlet frame, and both ends of the limiting pressure plate have limiting grooves on the inner surface of the corresponding wire outlet frame.

[0008] Furthermore, the limiting slide groove is provided with a limiting slider that is slidably connected to the corresponding limiting slide groove and fixedly connected to the corresponding limiting pressure plate, and a rubber pad is fixedly connected to the lower end face of the limiting pressure plate.

[0009] Furthermore, the upper end of the limiting pressure plate is provided with a limiting screw that is connected to the inside of the limiting pressure plate through a bearing for limiting rotation. The limiting screw passes through the corresponding wire frame and is threadedly connected to the through part.

[0010] Furthermore, a rotating handle is fixedly connected to the upper end of the limiting screw.

[0011] Furthermore, the positioning mechanism includes a limiting slide plate fixedly connected to the surface of the rotating column, and the limiting slide plate is slidably connected to the upper end face of the tee connector body.

[0012] Furthermore, a positioning hole evenly distributed in a circle is provided on the upper end face of the tee connector body below the limiting slide plate, and a limiting cylinder is fixedly connected to the upper end face of the limiting slide plate.

[0013] Furthermore, the limiting cylinder is provided with a pull block that is slidably connected to the inside of the limiting cylinder, and a positioning rod that penetrates the limiting slide plate and is slidably connected to the lower end face of the pull block is fixedly connected to the lower end face of the pull block.

[0014] Furthermore, the positioning rod is slidably connected to the positioning hole, and a pull rod is fixedly connected to the upper end face of the pull block through the limiting cylinder and slidably connected to the through part.

[0015] Furthermore, a pull ring is fixedly connected to the upper end of the pull rod, and springs are provided on the surface of the pull rod at both ends, which are respectively fixedly connected to the upper end of the pull block and the upper end of the inner part of the limiting cylinder.

[0016] The beneficial effects of this invention are as follows: This invention provides a tee connector for cable trays, which has the following advantages:

[0017] 1. Through the coordinated action of the outgoing wire frame, rotating adjustment plate, positioning mechanism, rotating column and through groove, the outgoing wire direction of the outgoing wire end can be limited and adjusted when the tee connector body is in use. This allows the cable tray to be laid according to the needs of the staff by adjusting to the appropriate outgoing wire direction, thus improving the performance of the tee connector body.

[0018] 2. The clamping mechanism can limit and clamp the cables appearing in the cable tray, which is beneficial for the laying of the cable tray.

[0033] Preferably, the clamping mechanism includes a limiting pressure plate 15 that is slidably connected to the inside of the corresponding wire outlet frame 2. Both ends of the limiting pressure plate 15 have limiting grooves 19 on the inner surface of the corresponding wire outlet frame 2.

[0034] Preferably, the limiting slide groove 19 is provided with a limiting slider 18 that is slidably connected to the corresponding limiting slide groove 19 and fixedly connected to the corresponding limiting pressure plate 15. The lower end face of the limiting pressure plate 15 is fixedly connected with a rubber pad 17. The limiting slider 18 can limit the sliding of the limiting pressure plate 15 in the wire frame 2.

[0035] Preferably, the upper end of the limiting pressure plate 15 is provided with a limiting screw 16 that is rotatably connected to the inside of the limiting pressure plate 15 through a bearing. The limiting screw 16 passes through the corresponding wire frame 2 and is threadedly connected to the through part. The limiting screw 16 can drive the limiting pressure plate 15 to move.

[0036] Preferably, a rotating handle 3 is fixedly connected to the upper end of the limiting screw 16, and the rotating handle 3 facilitates the rotation of the limiting screw 16.

[0037] Preferably, the positioning mechanism includes a limiting slide plate 7 fixedly connected to the surface of the rotating column 6, and the limiting slide plate 7 is slidably connected to the upper end face of the tee connector body 1.

[0038] Preferably, the limiting slide plate 7 has a positioning hole 5 evenly distributed in a circle on the upper end face of the tee connector body 1 below it, and the limiting cylinder 8 is fixedly connected to the upper end face of the limiting slide plate 7. The setting of the limiting cylinder 8 can limit the sliding of the pull block 13.

[0039] Preferably, the limiting cylinder 8 is provided with a pull block 13 that is slidably connected to the inside of the limiting cylinder 8. The lower end face of the pull block 13 is fixedly connected with a positioning rod 14 that passes through the limiting slide plate 7 and is slidably connected to the through part.

[0042] The specific working principle and usage method of this invention are as follows:

[0043] This invention provides a tee connector for cable trays. During cable tray installation, when workers need to adjust the orientation of the outlet end of the tee connector body 1 as required, they can pull the pull ring 9. The pull ring 9 drives the pull rod 11, which in turn moves the pull block 13 within the limiting cylinder 8. The pull block 13 then pulls the positioning latch 14 upwards, separating it from the corresponding positioning hole 5. This separation releases the limiting relationship on the rotating column 6, and consequently, the limiting relationship on the rotating adjustment plate 4. Then, workers can directly... By moving the cable outlet frame 2, the cable outlet frame 2 is rotated and adjusted by the action of the rotating adjustment plate 4 and the rotating column 6, thereby adjusting the orientation of the cable outlet end. After adjusting to the orientation required by the operator, the pull ring 9 is released, causing the pull block 13 to drive the pull rod 11 to descend under the action of the spring 12, thereby resetting the positioning latch 14 and allowing the positioning latch 14 to slide into the corresponding positioning hole 5, thus positioning the rotating column 6. At this time, the rotating adjustment plate 4 is also positioned along with the positioning of the rotating column 6, thus completing the limit adjustment of the orientation of the cable outlet frame 2, which is convenient for the operator to make limit adjustments according to the orientation requirements of the cable outlet.
