The bus duct suspension device comprises a bus duct clamp for fixing the bus duct and a suspender assembly for suspending the bus duct clamp on a ceiling;

the suspender component comprises a suspender and a sleeve which is in clearance fit with the outer diameter of the suspender; the upper end of the sleeve is fixedly connected with a ceiling, the lower end of the sleeve is provided with a plurality of fixed claws which are consistent with the length direction of the sleeve, the fixed claws are uniformly distributed along the circumferential direction of the sleeve, and extrusion gaps which are convenient for the fixed claws to extrude and fold are reserved between the adjacent fixed claws;

the lower end of the suspender is fixedly connected with the bus duct clamp, and a locking sleeve is slidably sleeved on the suspender; the locking sleeve is internally provided with a locking cavity with a wide upper part and a narrow lower part, the inner side wall of the locking cavity is provided with an internal thread, and the outer side wall of the fixed claw is provided with an external thread matched with the fixed claw.

Preferably, the bus duct clamp comprises an upper clamp and a lower clamp which are oppositely arranged, the two adjacent side walls of the upper clamp and the lower clamp are respectively provided with a transverse folding edge, and the two opposite transverse folding edges are fixedly connected through a locking bolt.

Preferably, a mounting plate is fixed at the top end of the sleeve, and the mounting plate is fixedly connected with a ceiling through a fixing bolt.

The utility model has the advantages that: the hanger rod is in clearance fit with the sleeve, the lower end of the sleeve is provided with the fixed claw, the hanger rod is provided with the locking sleeve matched with the fixed claw, and the fixed claw is extruded and folded by rotating the locking sleeve, so that the hanger rod is fixedly connected with the sleeve, and the hanger rod is simple in structure and convenient to install; meanwhile, the hoisting height of the bus duct can be adjusted by loosening the locking sleeve, moving the suspender to the required height and locking the suspender, and the use is flexible.

Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

As shown in fig. 1 and 2, the bus duct suspension device comprises a bus duct clamp for fixing the bus duct 1 and a hanger assembly for suspending the bus duct clamp on a ceiling; the bus duct clamp comprises an upper clamp 2 and a lower clamp 3 which are oppositely arranged, two adjacent side walls of the upper clamp 2 and the lower clamp 3 are respectively provided with a transverse folded edge 4, and the two opposite transverse folded edges 4 are fixedly connected through a locking bolt 5; when the bus duct 1 is installed, the bus duct 1 only needs to penetrate through the upper clamp 2 and the lower clamp 3, then the locking bolt 5 is screwed down, and the relative distance between the upper clamp 2 and the lower clamp 3 is changed, so that the bus duct 1 can be clamped and fixed.

The suspender component comprises a suspender 6 and a sleeve 7 which is in clearance fit with the outer diameter of the suspender 6; a mounting plate 8 is fixed at the top end of the sleeve 7, and a fixing bolt 9 penetrates through the mounting plate 8 to fixedly connect the sleeve 7 with a ceiling; the lower end of the sleeve 7 is provided with a plurality of fixed claws 10 (as shown in fig. 3) which are consistent with the length direction of the sleeve, the fixed claws 10 are uniformly distributed along the circumferential direction of the sleeve 7, and extrusion gaps 11 which are convenient for the fixed claws 10 to be extruded and folded are reserved between the adjacent fixed claws 10; the lower end of the suspender 6 is fixedly connected with the top of the upper clamp 2, and a locking sleeve 12 is slidably sleeved on the suspender 6; a locking cavity 13 with a wide upper part and a narrow lower part is formed in the locking sleeve 12, an internal thread is arranged on the inner side wall of the locking cavity 13, and an external thread matched with the external thread is arranged on the outer side wall of the fixed claw 10; when in hoisting, the bus duct 1 is hoisted high, and the upper end of the suspender 6 is inserted into the sleeve 7 and ascends along the sleeve 7; after the bus duct 1 is lifted to a required height, the locking sleeve 12 is lifted, the lower end of the fixed claw 10 is inserted from the top of the locking sleeve 12, then the locking sleeve 12 is rotated, the locking sleeve 12 is gradually in threaded connection with the fixed claw 10 along with rotation, and the fixed claw 10 can be squeezed and folded under the action of the locking cavity 13 due to the fact that the locking cavity 13 is wide at the top and narrow at the bottom, so that the suspender 6 is clamped and fixed, the structure is simple, and installation is convenient; when the hoisting height of the bus duct 1 needs to be adjusted, the locking sleeve 12 only needs to be loosened, and then the suspender 6 is moved to the required height and locked, so that the use is flexible.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
