Description

Technical Field

[0001] The present disclosure relates to the technical field of lamps, and in particular to an anti-twisting wire device for a rotating lamp and a lighting device. Background Art

[0002] Remote control lights refer to lights that work through signal instructions. They can generally rotate or swing to adjust the light direction of the lights. They are suitable for use in scenes such as stages or banquet halls. The two ends of the internal wire of a rotating remote control light are connected to the external circuit and the light source respectively. When the light source of the rotating remote control light rotates, one end of the wire rotates with the light source, causing the entire wire to twist, which in turn causes the internal wire of the wire to break, posing a safety hazard of wire short circuit.

[0003] In order to solve the above problems, a Chinese patent with application number CN202211538277.0 discloses an anti-twisting wire joint structure, including a shell, the shell having a cavity; an end cover, the end cover is a hollow structure, and one end is enclosed to form a first wire inlet hole, and the other end is movably connected to one end of the shell; a base, the base is movably connected to the other end of the shell; a fixing part, the fixing part is movably arranged in the cavity of the shell, the fixing part includes a head and a bottom, the bottom is clamped with the inner wall of the base, and the head is abutted against the inner wall of the end cover; the head is provided with a second wire inlet hole, and the bottom is provided with a plurality of first wire core holes.

[0034] In the above-mentioned anti-twisting wire device, the light source part is installed on the rotating bracket, and the power output end of the rotating driving part drives the rotating bracket to rotate. The anti-twisting wire structure includes a first stator column, a second stator column and a connecting boss, the connecting boss is connected to the connecting frame, the first stator column is provided with a first wire channel, the second stator column is provided with a second wire channel, one end of the stator wire passes through the first wire channel and the second wire channel in turn and is electrically connected to the rotor wire, the other end of the stator wire is electrically connected to the power supply, and the other end of the rotor wire is electrically connected to the light source part. When the rotating bracket drives the light source part to rotate, the rotor wire also rotates together, and the stator wire is covered by the first stator column and the second stator column, that is, the stator wire will not rotate, thus avoiding the twisting of the entire wire, and thus avoiding the internal wire of the wire from being twisted and broken. Furthermore, since the first stator column, the second stator column and the connecting boss are integrally formed, the anti-twisting wire structure is relatively simple and has high strength.

[0035] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0036] like Figures 1 to 7 As shown, an anti-twisting wire device 10 for a rotating lamp of one embodiment includes a lamp housing 100, a rotating driving member 200, a connecting frame 300, a rotating bracket 400 and a light source member 500, wherein the connecting frame 300 is installed inside the lamp housing 100, the rotating driving member 200 is installed on the connecting frame 300, the power output end of the rotating driving member 200 is fixedly connected to the rotating bracket 400, the rotating bracket 400 is slidably connected to the inner wall of the lamp housing 100, and the light source member 500 is installed on the rotating bracket 400 so that the rotating bracket 400 drives the light source member 500 to rotate.

[0037] Furthermore, the anti-twisting wire device 10 for a rotating lamp also includes a wire member 600 and an anti-twisting wire structure 700, the wire member 600 includes a stator wire 610 and a rotor wire 620, the anti-twisting wire structure 700 includes an integrally formed first stator column 710, a second stator column 720 and a connecting boss 730, the first stator column 710 and the second stator column 720 are fixedly connected, the connecting boss 730 is connected to the periphery of the first stator column 710, the connecting boss 730 is connected to the connecting frame 300, the first stator column 710 is provided with a first wire channel 711, the second stator column 720 is provided with a second wire channel 721, the first wire channel 711 is connected to the second wire channel 721, the stator wire 610 passes through the first wire channel 711 and the second wire channel 721 in sequence and is electrically connected to the rotor wire 620, so that one end of the stator wire 610 is covered by the first stator column 710 and the second stator column 720.

[0038] In the present embodiment, one end of the stator wire 610 passes through the lamp housing 100 and is electrically connected to the external circuit, and the other end of the stator wire 610 passes through the first wire channel 711 and the second wire channel 721 and is electrically connected to the rotor wire 620, so that one end of the stator wire 610 is covered in the first stator column 710 and the second stator column 720, and the other end of the rotor wire 620 is electrically connected to the light source component 500. When the rotating driving component 200 drives the rotating bracket 400 to rotate, the light source component 500 on the rotating bracket 400 rotates together, thereby driving the rotor wire 620 to rotate together. Since the stator wire 610 is covered in the first stator column 710 and the second stator column 720, that is, the stator wire 610 is interference-contacted with the first stator column 710 and the second stator column 720, the stator wire 610 will not rotate, thereby avoiding the situation where the entire wire is twisted, thereby avoiding the problem of wire twisting and wire short circuit. Furthermore, the rotary driving member 200 is a motor.

[0039] In the above-mentioned anti-twist wire device, the light source part 500 is installed on the rotating bracket 400, and the power output end of the rotating driving part 200 drives the rotating bracket 400 to rotate. The anti-twist wire structure 700 includes a first stator column 710, a second stator column 720 and a connecting boss 730. The connecting boss 730 is connected to the connecting frame 300. The first stator column 710 is provided with a first wire channel 711, and the second stator column 720 is provided with a second wire channel 721. One end of the stator wire 610 passes through the first wire channel 711 in sequence. After the second wire channel 721 is connected, it is electrically connected to the rotor wire 620. The other end of the stator wire 610 is electrically connected to the power supply, and the other end of the rotor wire 620 is electrically connected to the light source 500. When the rotating bracket 400 drives the light source 500 to rotate, the rotor wire 620 also rotates together. Since the stator wire 610 is covered by the first stator column 710 and the second stator column 720, the stator wire 610 will not rotate, thus avoiding the twisting of the entire wire and thus avoiding the twisting of the wire inside the wire. Furthermore, since the first stator column 710, the second stator column 720 and the connecting boss 730 are integrally formed, the anti-twisting wire structure 700 is relatively simple and has a higher strength.

[0040] In one embodiment, the first stator column 710, the second stator column 720 and the connecting boss 730 are an integral injection molding structure. It can be understood that the first stator column 710, the second stator column 720 and the connecting boss 730 are formed by an integral injection molding process to make the structure more compact and higher in strength.

[0041] like Figure 4 As shown, in one embodiment, the cross-sectional area of ​​the first stator column 710 is greater than the cross-sectional area of ​​the second stator column 720. It can be understood that the second stator column 720 abuts against the clamping hole of the rotating bracket 400 to ensure the structural strength of the lamp as a whole, and the cross-sectional area of ​​the second stator column 720 needs to be adapted to the aperture of the clamping hole.

[0042] like Figure 2 and Figure 5 As shown, in one embodiment, the anti-twisting wire device 10 for a rotating lamp further includes a screw connection member, a first screw connection hole 731 is provided at the periphery of the connecting boss 730, and a second screw connection hole is provided at the connecting frame 300, and the screw connection member sequentially passes through the first screw connection hole 731 and the second screw connection hole to screw the connecting boss 730 with the connecting frame 300. It can be understood that the connecting boss 730 is screwed with the connecting frame 300 through the screw connection member to fix the connecting boss 730 with the connecting frame 300.

[0043] like Figure 5As shown, in one embodiment, the cross-sectional area of ​​the connecting boss 730 is annular, so that the connecting boss 730 is adapted to the installation position of the connecting frame 300. Of course, in other embodiments, the connecting boss 730 can also be other shapes such as rectangular or elliptical.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, the number of the first wire channels 711 is two, and the two first wire channels 711 are both connected to the second wire channel 721, so that multiple wires can pass through the first stator column 710 from different directions.

[0045] like Figure 4 and Figure 5 As shown, in one embodiment, two first wire channels 711 are spaced apart and distributed on the periphery of the first stator column 710 , so that the wires enter the first stator column 710 through the first wire channels 711 on the two side edges respectively.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the lamp housing 100 includes an upper cover 110, an intermediate housing 120 and a lower housing 130 connected in sequence, the connecting frame 300 is connected to the upper cover 110, and the lower housing 130 is slidably connected to the rotating bracket 400. In this embodiment, the connecting frame 300 is screwed to the upper cover 110 by screws, and the lower housing 130 is slidably connected to the rotating bracket 400, so that when the rotating driving member 200 is working, the rotating bracket 400 rotates relative to the lower housing 130. Further, the lower housing 130 also supports the rotating bracket 400.

[0047] like Figure 3 As shown, in one embodiment, a ball bearing member 410 is provided at one end of the rotating bracket 400 adjacent to the lower shell 130, and the ball bearing member 410 includes a mounting ring 411 and a ball 412. The rotating bracket 400 is provided with an embedding groove 420, and the mounting ring 411 is embedded in the embedding groove 420. The mounting ring 411 is provided with a mounting hole, and the ball 412 is located in the mounting hole and respectively abuts against the rotating bracket 400 and the lower shell 130. In this embodiment, the mounting ring 411 is clamped in the embedding groove 420, a part of the structure of the lower shell 130 is embedded in the embedding groove 420 and abuts against the ball 412, the ball 412 is located in the mounting hole and abuts against the rotating bracket 400, and when the rotating driving member 200 drives the rotating bracket 400 to rotate, the ball 412 rolls, that is, the friction between the rotating bracket 400 and the lower shell 130 is reduced through the rolling abutment of the ball 412, so that the rotating bracket 400 can rotate better.

[0048] The present application also provides a lighting device, comprising the anti-twisting wire device 10 for a rotating lamp as described in any of the above embodiments.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] In the above-mentioned anti-twist wire device, the light source part 500 is installed on the rotating bracket 400, and the power output end of the rotating driving part 200 drives the rotating bracket 400 to rotate. The anti-twist wire structure 700 includes a first stator column 710, a second stator column 720 and a connecting boss 730. The connecting boss 730 is connected to the connecting frame 300. The first stator column 710 is provided with a first wire channel 711, and the second stator column 720 is provided with a second wire channel 721. One end of the stator wire 610 passes through the first wire channel 711 in sequence. After the second wire channel 721 is connected, it is electrically connected to the rotor wire 620. The other end of the stator wire 610 is electrically connected to the power supply, and the other end of the rotor wire 620 is electrically connected to the light source 500. When the rotating bracket 400 drives the light source 500 to rotate, the rotor wire 620 also rotates together. Since the stator wire 610 is covered by the first stator column 710 and the second stator column 720, the stator wire 610 will not rotate, thus avoiding the twisting of the entire wire and thus avoiding the twisting of the wire inside the wire. Furthermore, since the first stator column 710, the second stator column 720 and the connecting boss 730 are integrally formed, the anti-twisting wire structure 700 is relatively simple and has a higher strength.

[0051] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
