Preferably, at least one section of the gradually narrowing channel 221 gradually narrowing toward the two spiral turns 21 is provided in the outer torque arm 22.

Preferably, the tapered channel 221 is formed with a U-shaped connection 222 at the outer torque arm 22 at the end away from the two coils 21.

Preferably, the outer wall of the outer cylinder body 1 near the mounting part 11 is provided with a rivet 12 for riveting the elastic sheet 3 when the elastic sheet 3 is replaced without using the torsion spring 2, and/or the wall of the outer cylinder body 1 near the mounting part 11 is provided with a screw hole 13 for fixing the elastic sheet 3 by a screw when the elastic sheet 3 is replaced without using the torsion spring 2.

Compared with the prior art, the utility model has the beneficial effects that:

1. the structure of the scheme is simple and easy to realize, the arrangement of the transverse bulges at the left end and the right end of the mounting part is convenient for the spiral coils at the left end and the right end of the torsion spring to be respectively sleeved on the corresponding transverse bulges, and the torsion spring mounting structure is convenient to assemble and disassemble and has good practicability; in addition, the outside torque arm is connected in the setting between left side helicoid and the right side helicoid, and the outside torque arm of being convenient for forms closed shape and can not fish tail assembly personnel, and the practicality is good.

2. The outside torque arm is equipped with one section gradually to the passageway of narrowing gradually that two helicoidal directions narrowed at least in, work as outside torque arm atress makes when the passageway of narrowing gradually enlarges, the passageway both sides arm pole of narrowing gradually has the trend to the middle part motion, and two helicoidal of drive that can be more powerful are close to each other, make two helicoidal be difficult for following horizontal protruding accident and drop, are favorable to improving the steadiness, and the practicality is good.

Detailed Description

The features of the present invention and other related features are further described in detail below by way of examples to facilitate understanding by those skilled in the art:

as shown in fig. 1 to 4, an outer cylinder structure of a down lamp comprises an outer cylinder body 1, the outer side wall of the outer cylinder body 1 is provided with a plurality of installation parts 11 used for supplying a torsion spring 2 to install the outer cylinder body, the left end and the right end of the installation parts 11 are respectively provided with a transverse protrusion 111, the left end and the right end of the torsion spring 2 are respectively provided with a spiral coil 21 used for being sleeved on the corresponding transverse protrusion 111, and one end of the left spiral coil 21 and one end of the right spiral coil 21 both extend outwards and are connected together to form a closed outer side torque arm 22.

As mentioned above, the structure of the present invention is simple and easy to implement, the arrangement of the transverse protrusions 111 at the left and right ends of the mounting portion 11 facilitates the spiral coils 21 at the left and right ends of the torsion spring 2 to be respectively sleeved on the corresponding transverse protrusions 111 from the outside, and the present invention has the advantages of convenient assembly, convenient disassembly and good practicability; in addition, the arrangement that outside torque arm 22 is connected between left side spiral coil 21 and right side spiral coil 21 is convenient for outside torque arm 22 to form closed shape and can not fish tail assembly personnel, and the practicality is good.

As described above, in practical implementation, the other end of the coil 21 may abut against the inner sidewall of the outer cylinder body 1 or be fixed in a hole of the outer cylinder body 1 so as to provide a supporting force.

As shown in fig. 3, in the specific implementation, at least one gradually narrowing channel 221 that gradually narrows toward the two coils 21 is provided in the outer torque arm 22, and when the outer torque arm 22 is forced to expand the gradually narrowing channel 221, the arm levers on both sides of the gradually narrowing channel 221 have a tendency to move toward the middle, so that the two coils 21 can be driven to approach each other more powerfully, and the two coils 21 are not easily accidentally dropped from the transverse protrusion 111, which is beneficial to improving the stability and the practicability.

In particular, as shown in fig. 3, the tapered channel 221 is formed with a U-shaped connection 222 at the end of the outer torsion arm 22 away from the two coils 21 to facilitate smooth contact with the outer wall.

As shown in fig. 2 and 4, in specific implementation, a rivet 12 for riveting the elastic sheet 3 when the elastic sheet 3 is replaced without using the torsion spring 2 is disposed on the outer wall body of the outer cylinder body 1 near the mounting portion 11, and/or a screw hole 13 for fixing the elastic sheet 3 by a screw when the elastic sheet 3 is replaced without using the torsion spring 2 is disposed on the wall body of the outer cylinder body 1 near the mounting portion 11, so that the elastic sheet 3 can be selected and installed as required, and the market competitiveness can be improved.

As described above, the present application protects an outer cylinder structure of a down lamp, and all technical solutions identical or similar to the present application should be considered to fall within the protection scope of the present application.
