Installation structure of assembled indoor unit electric wire pipe

Abstract

This invention provides an installation structure for a prefabricated indoor unit electrical conduit, relating to the field of electrical conduit installation. The invention includes an electrical conduit with a mounting bracket on its outer side. Multiple elastic bands are mounted on the outer side of the mounting bracket, with adjacent elastic bands in contact. A lifting mechanism is provided at both the top and bottom of the electrical conduit, and a connecting structure is provided on the outer side of the electrical conduit. The arc-shaped guide surface of this invention is designed to prevent other elastic bands from being moved by a pry bar. The pry bar and protrusion lift the elastic bands located on the mounting bracket and restricted by a stop block. The elastic bands pass through the hinged rod, the electrical conduit, and the arc-shaped guide surface formed on the electrical conduit, and then detach from the electrical conduit, thereby bundling the electrical wires. This allows multiple electrical wires to be bundled after being threaded through the conduit, facilitating the threading of subsequent wires. Furthermore, after threading, no additional clamping structures are needed to bind the wires, keeping the multiple wires neatly arranged.

[0029] The lifting and dropping mechanism includes an articulated rod 4, a through hole 6 is opened on the wire casing 1, the articulated rod 4 extends through the through hole 6 to the inside of the wire casing 1, an axle pin 5 is provided in the middle of the articulated rod 4, the wire casing 1 and the articulated rod 4 are movably connected through the axle pin 5, a rotating shaft 7 is provided at the bottom end of the articulated rod 4, the rotating shaft 7 and the wire casing 1 are movably connected through a bearing, a round tube 8 is provided on the outside of the rotating shaft 7, the round tube 8 is rotatably connected to the rotating shaft 7, an eccentric wheel 9 is provided on the outside of one end of the round tube 8, The eccentric wheel 9 is fixedly connected to the round tube 8, and the eccentric wheel 9 contacts the bottom end of the hinged rod 4. A pry bar 10 is provided at the top of the hinged rod 4, and the pry bar 10 is fixedly connected to the hinged rod 4. A protrusion 11 is provided on the top of one end of the pry bar 10, and the protrusion 11 and the pry bar 10 are cast as one piece. An arc-shaped guide surface 13 is formed on one side of the protrusion 11, and the arc-shaped guide surface 13 is set as a smooth inclined surface. A limiting block 12 is provided at the bottom of one end of the pry bar 10, and the limiting block 12 is fixedly connected to the pry bar 10.

[0030] The placement rack 2 is provided with a prefabricated hole 16 , and one end of the pry bar 10 passes through the prefabricated hole 16 and extends to the inside of the placement rack 2 . A stopper 14 is fixedly connected to the outside of the placement rack 2 .

[0031] A guiding arc-shaped slope 25 is formed at one end of the wire sleeve 1, and the guiding arc-shaped slope 25 has an inclined angle.

[0032] When the present invention is in use, the wire is inserted through the wire casing 1. When the wire passes through the wire casing 1, the outside of the wire will contact the round tube 8. At this time, the round tube 8 is restricted and supported by the rotating shaft 7, and at the same time, it will rotate due to the friction when the wire passes through. The round tube 8 drives the eccentric wheel 9 on its outside to move in a circle. The eccentric wheel 9 will contact the bottom end of the hinged rod 4 when rotating. Since the middle part of the hinged rod 4 is supported by the fulcrum of the shaft pin rod 5, the top end of the hinged rod 4 can move in the opposite direction relative to the bottom end of the hinged rod 4. The top end of the hinged rod 4 has the ability to drive the pry bar 10 to disengage from the inside of the prefabricated hole 16. When the pry bar 10 is tilted, the position The protrusion 11 at the top of the pry bar 10 hooks one of the rubber bands 3 on the placement rack 2. The arc guide surface 13 is set at this time to prevent other rubber bands 3 from being driven by the pry bar 10. At this time, the pry bar 10 and the protrusion 11 will pick up the rubber band 3 on the placement rack 2 and restricted and blocked by the block 14. The rubber band 3 passes through the hinged rod 4 and the wire sleeve 1 and the guide arc slope 25 formed on the wire sleeve 1, and then detaches from the wire sleeve 1, so that the wires are bundled. In this way, multiple wires can be bundled after being inserted into the pipe, which is convenient for threading the subsequent wires. At the same time, there is no need to use other clamp structures to bundle the wires after threading, so that the multiple wires after threading can be kept neat.

[0033] When the eccentric wheel 9 is disengaged from the hinge rod 4, the pry bar 10 is reset and enters the prefabricated hole 16. At this time, the arc-shaped guide surface 13 still reduces the friction with the rubber band 3, facilitating the entry of the pry bar 10 and the protrusion 11. The limiting block 12 inclined at the bottom of the pry bar 10 can prevent the rubber band 3 from moving away, causing the pry bar 10 to rest on the top of the rubber band 3 and squeeze the rubber band 3, thereby preventing the rubber band 3 from falling normally and facilitating the bundling of wires.

[0034] The connecting structure includes a ring 17, an internal thread 18 is formed on the inner side of the ring 17, and an external thread is formed on the outer side of the wire sleeve 1. The ring 17 and the wire sleeve 1 are threadedly connected through the cooperation of the internal thread 18 and the external thread on the wire sleeve 1. The ring 17 serves to facilitate the connection. A connecting rod 20 is provided at the bottom of the ring 17. A slot 19 is provided at the bottom of the ring 17.

Since a slot 19 is provided on the collar 17, and the connecting rod 20 and the collar 17 are slidably connected through the slot 19, the straight rod 21 located at the bottom of the connecting rod 20 is in a movably plug-in relationship with the connecting rod 20, and since a connecting hole 24 is provided on the straight rod 21, a fastening bolt 23 is provided on the front side of the connecting rod 20. When the connecting rod 20 is connected to the straight rod 21, the fastening bolt 23 can be passed through the connecting rod 20 and connected into the inside of the connecting hole 24, so that the connecting structure supports the wire sleeve 1, and the mounting hole on the connecting seat 22 can be used for installation using bolts.

[0036] Working principle: Since the middle part of the hinged rod 4 is acted upon by the fulcrum of the axle pin rod 5, the top end of the hinged rod 4 can move in the opposite direction relative to the bottom end of the hinged rod 4, and the top end of the hinged rod 4 has the ability to drive the pry bar 10 to detach from the prefabricated hole 16. When the pry bar 10 is tilted, the protrusion 11 at the top of the pry bar 10 hooks one of the rubber bands 3 on the placement rack 2. The arc-shaped guide surface 13 is provided at this time to prevent other rubber bands 3 from being driven by the pry bar 10. At this time, the pry bar 10 and the protrusion 11 will pick up the rubber band 3 on the placement rack 2 and restricted and blocked by the block 14. The rubber band 3 passes through the hinged rod 4 and the wire sleeve 1 and the guide arc-shaped slope 25 formed on the wire sleeve 1, and then detaches from the wire sleeve 1, thereby bundling the wires. In this way, multiple wires can be bundled after being inserted into the pipe.

[0037] When the eccentric wheel 9 is disengaged from the hinge rod 4, the pry bar 10 is reset and enters the prefabricated hole 16. At this time, the arc-shaped guide surface 13 still reduces the friction with the rubber band 3, facilitating the entry of the pry bar 10 and the protrusion 11. The limiting block 12 inclined at the bottom of the pry bar 10 can prevent the rubber band 3 from moving away, causing the pry bar 10 to rest on the top of the rubber band 3 and squeeze the rubber band 3.

[0038] A collar 17 is provided on the outside of the wire sleeve 1, and the collar 17 is threadedly connected to the wire sleeve 1 through an internal thread 18 formed on the inner side. Since a slot 19 is provided on the collar 17, and the connecting rod 20 and the collar 17 are slidably connected through the slot 19, the straight rod 21 located at the bottom of the connecting rod 20 is in a movably plug-in relationship with the connecting rod 20, and since a connecting hole 24 is provided on the straight rod 21, a fastening bolt 23 is provided on the front side of the connecting rod 20. When the connecting rod 20 is connected to the straight rod 21, the fastening bolt 23 can be passed through the connecting rod 20 and connected into the inside of the connecting hole 24, so that the connecting structure supports the wire sleeve 1.
