Description

Torsion spring and lamps with it

technical field

The utility model relates to an elastic element and a lamp with it, in particular to a torsion spring and a lamp with it.

Background technique

Traditional lamps are mainly fluorescent lamps and incandescent bulbs. As the luminous efficiency of light-emitting diodes (Light Emitting Diode, LED) continues to increase, light-emitting diodes are gradually replacing fluorescent lamps and incandescent bulbs and are used in lamps. Compared with traditional light bulbs, light-emitting diodes have absolute advantages, such as small size, long life, low voltage/current drive, not easy to break, mercury-free (no pollution problem), and good luminous efficiency (power saving).

As far as the indoor lamp is concerned, it can be fixed on the fixed end of the building (such as the ceiling or the wall) by virtue of the elastic force of the torsion spring assembled on the lamp. The existing torsion spring usually has a spring body and two spring arms connected to the two ends of the spring body. When the lamp is fixed on the fixed end of the building, the two spring arms will respectively press against the housing of the lamp and the fixed end of the building. Since the spring arm is a slender structure connected to the end of the spring body, it is a concentrated load when it is stressed, so it is easy to deform under force and is relatively unstable in structure. In addition, it is difficult to assemble the torsion spring with such a structure, and it needs to be assembled with jigs, which is time-consuming.

The fourth spring arm 136c extends from an end of the second bent portion 136b away from the third spring arm 136a to the first end 132a of the spring body 132 .

Fig. 4 is a partial side view of the torsion spring fixed to the fixed end of the lamp in Fig. 1 . Please refer to FIG. 4 , the lamp 100 of this embodiment (shown in FIG. 1 ) is adapted to be fixed on a fixed end 50 , such as a part of a ceiling or a wall of a building. When the fixed end 50 and the assembly part 112 of the housing 110 are located between the first supporting part 134 and the second supporting part 136, the first spring arm 134a and the second spring arm 134c are held together by the elastic force of the spring body 132. The third spring arm 136 a and the fourth spring arm 136 c are pressed against the fixed end 50 by the elastic force of the spring body 132 .

In other words, when the user intends to fix the lamp 100 (shown in FIG. 1 ) on the fixed end 50 , the first supporting portion 134 and the second supporting portion 136 can be opened against the elastic force of the spring body 132 . There is an angle A between them, so that the first bearing part 134 and the second bearing part 136 can respectively bear against the assembly part 112 and the fixed end 50 in the manner shown in FIG. Press against the assembly part 112 and the fixed end 50 to fix the lamp 100 on the fixed end 50 . Please refer to FIG. 1 and FIG. 4 , it is worth noting that the lamp 100 of this embodiment is configured with two torsion springs 130 , and the two torsion springs 130 are located on opposite sides of the lamp. The two torsion springs 130 can be pressed against the fixed end 50 and the housing 110 at the same time, so that the lamp 100 is firmly fixed on the fixed end 50 .

In addition, please refer to FIG. 2 and FIG. 3 , in this embodiment, since the first abutting portion 134 and the second abutting portion 136 of the torsion spring 130 all have double spring arms (the first abutting portion 134 has a first spring arm 134a and the second spring arm 134c, the second supporting part 136 has the third spring arm 136a and the fourth spring arm 136c), so the user is easy to open it with bare hands. Therefore, in the process of assembling the torsion spring 130 to the assembling portion 112 of the casing 110 , the user can complete the assembling quickly without using jigs.

The structure of the torsion spring of this embodiment will be described in more detail below. Please refer to FIG. 3 , in this embodiment, the first spring arm 134 a and the second spring arm 134 c are substantially parallel to each other and substantially perpendicular to the first bending portion 134 b. The third spring arm 136a and the fourth spring arm 136c are substantially parallel to each other and substantially perpendicular to the second bending portion 136b. In addition, the second supporting portion 136 further includes an extension arm 136d connected to an end of the fourth spring arm 136c away from the second bending portion 136b and extending from the first end 132a of the spring body 132 into the spring body 132 . The first supporting portion 134 further includes an extension arm 134d connected to an end of the second spring arm 134c away from the first bending portion 134b and extending from the second end 132b of the spring body 132 into the spring body 132 .

The extension arm 134d and the extension arm 136d are substantially perpendicular to the second spring arm 134c and the fourth spring arm 136c respectively, and are installed in the spring body 132, so as to restrict the structural interference between the spring body 132 and the second spring arm 136c. The movement range of the ends of the second spring arm 134c and the fourth spring arm 136c adjacent to the spring body reduces the probability of the torsion spring 130 being bent and damaged due to improper external force.

To sum up, in the lamp of the present invention, the two supporting parts of the torsion spring both have two spring arms, so the load is relatively balanced when the force is applied, and it has high structural strength. Since the supporting part has two spring arms, the user can easily pull them directly, so the assembly is more convenient. In addition, the torsion spring can have an extension connected to the spring arm and passed through the spring body, so as to reduce the probability of the torsion spring being bent and damaged by external force through the structural interference between the extension and the spring body.
