Description

Technical Field

[0001] The utility model relates to the technical field of table lamps, in particular to a positioning and rotating component of an intelligent eye protection table lamp. Background Art

[0002] At present, an eye protection table lamp mainly consists of a light source and a lamp. The lamp head usually has a light source with relatively good light quality. The lamp is composed of a lampshade that can improve the uniformity of light distribution and weaken or reduce glare, and a drive circuit that provides current to the light source.

[0003] In order to adjust the illumination angle of the lamp head of the table lamp, the lamp head of the table lamp is generally hinged through structures such as bolts. And since the joints at the lamp head transfer positions of traditional desktop eye protection table lamps in the market all adopt outgoing wire type (non-hidden wire) joints, the wires inside the lamp head are led out into the lamp pole. In this way, the wires may be broken during the rotation process, resulting in an electric shock risk. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a positioning and rotating component of an intelligent eye protection table lamp, in which a perforated through hole is provided in the rotating shaft for wire routing, and the lamp head is rotationally limited relative to the lamp pole with the rotating shaft, reducing the situation of wire breakage caused by rotation.

[0005] The purpose of the utility model is achieved by adopting the following technical solutions:

[0006] A positioning and rotating component of an intelligent eye protection table lamp includes a first connecting block, a second connecting block and a rotating shaft mechanism. The first connecting block is used to connect to the lamp head, the second connecting block is used to connect to the lamp pole. The rotating shaft mechanism includes a rotating shaft and a limiting piece. One end of the rotating shaft is rotatably inserted into the first connecting block; the other end of the rotating shaft is connected to the second connecting block, and the limiting piece is connected to the rotating shaft; a limiting block is provided on the first connecting block, and the limiting block is used to abut against the limiting piece to limit the rotation range of the rotating shaft; a wire passing through hole is provided in the rotating shaft.

[0007] Further, the lamp head is provided with a connecting plate, and the first connecting block is connected to the connecting plate; the rotating shaft mechanism further includes a connecting head located inside the lamp head; one end of the rotating shaft is provided with a limiting head, and the other end of the rotating shaft is provided with a threaded section; the threaded section passes through the second connecting block, and after passing through the second connecting block, the threaded section rotatably passes through the first connecting block and is screwed to the connecting head, so that the connecting plate is clamped between the first connecting block and the connecting head, and the limiting head abuts against the inner side of the second connecting block.

[0008] Furthermore, a first damping gasket is sandwiched between the outer side of the second connecting block and the outer side of the first connecting block.

[0009] Furthermore, a second damping gasket is clamped between the inner side of the first connecting block and the connecting head.

[0010] Furthermore, the limiting plate is sleeved outside the rotating shaft and is located between the first damping washer and the first connecting block.

[0011] Furthermore, the connecting plate is provided with a first mounting groove, and the first connecting block is embedded in the first mounting groove.

[0012] Furthermore, a first flat surface is provided on the outer surface of the rotating shaft; a connecting hole is provided on the second connecting block; a second flat surface is provided on the inner wall of the connecting hole; the rotating shaft passes through the connecting hole, and the first flat surface and the second flat surface abut against each other to prevent the rotating shaft and the second connecting block from rotating.

[0013] Furthermore, the lamp pole is provided with a second mounting groove, the second connecting block is embedded in the second mounting groove; and the connecting hole is provided in the second mounting groove.

[0014] Furthermore, the first connecting block and the second connecting block are arranged in a vertical state.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the lamp head rotates, the lamp head rotates relative to the rotating shaft through the first connecting block, so that the internal circuit is inside the rotating shaft, which is different from the traditional situation where the wires are exposed. The hidden wires prevent users from directly contacting the wires, reduce the risk of electric shock caused by human-caused wire skin breakage, and greatly improve safety and reliability. In addition, since a limit block is also provided on the first connecting block of the lamp head, when the lamp head rotates, the limit block will abut against the limit plate on the rotating shaft, thereby limiting the rotation range of the lamp head. Since the rotation range of the lamp head is limited, the wires will not be entangled 360 degrees, so the user is prevented from excessively rotating the lamp head, causing the internal wires to break the wires and causing adverse risks.

Specific embodiments

[0023] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described:

[0024] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0026] Such as Figures 1 - 5The smart eye protection desk lamp positioning and rotating assembly shown includes a first connecting block 31, a second connecting block 32 and a rotating shaft mechanism, wherein the first connecting block 31 is connected to the lamp holder 10, and the second connecting block 32 is connected to the lamp pole 20. The specific rotating shaft mechanism includes a rotating shaft 33 and a limiting plate 34, and one end of the rotating shaft 33 is rotatably connected to the first connecting block 31, and the other end of the rotating shaft 33 is connected to the second connecting block 32. The above-mentioned limiting plate 34 is connected to the rotating shaft 33. A limiting block 311 is provided on the first connecting block 31. During the rotation of the rotating shaft 33, the limiting plate 34 on the rotating shaft 33 can abut against the limiting block 311 to limit the rotation range of the rotating shaft 33; a threading through hole 331 is provided in the rotating shaft 33.

[0027] On the basis of the above structure, when the intelligent eye protection desk lamp positioning rotating assembly of the utility model is used, the first connecting block 31 of the above-mentioned rotating shaft mechanism is connected to the lamp holder 10, the second connecting block 32 of the rotating shaft mechanism is connected to the lamp pole 20, and one end of the rotating shaft 33 is rotatably connected to the first connecting block 31, and the other end of the rotating shaft 33 is connected to the second connecting block 32, and the line of the light source in the lamp holder 10 can be guided to the inside of the lamp pole 20 through the threading hole 331 of the rotating shaft 33, and then guided to the circuit board through the inside of the lamp pole 20. In this way, when the lamp holder 10 rotates, the lamp holder 10 rotates relative to the rotating shaft 33 through the first connecting block 31, so that the internal circuit is inside the rotating shaft 33, which is different from the traditional situation of external leakage of electric wires. The hidden wire passing prevents users from directly contacting the wire passing wires, reduces the risk of electric shock caused by human-caused wire passing wire skin breakage, and greatly improves safety and reliability.

[0028] In addition, since a limit block 311 is also provided on the first connecting block 31 of the lamp head 10, when the lamp head 10 rotates, the limit block 311 will abut against the limit plate 34 on the rotating shaft 33, thereby limiting the rotation range of the lamp head 10. Since the rotation range of the lamp head 10 is limited, the wire will not be entangled 360 degrees, thereby preventing the user from excessively rotating the lamp head 10, resulting in the risk of internal wires being broken and excessive wires being generated.

[0029] Specifically, a connecting plate 11 may be provided on the lamp holder 10, and the first connecting block 31 may be connected to the connecting plate 11. The rotating shaft mechanism further includes a connecting head 35, and the connecting head 35 is located inside the lamp holder 10. A stopper 332 is provided at one end of the rotating shaft 33, and a threaded section 333 is provided at the other end of the rotating shaft 33. During assembly, the threaded section 333 of the rotating shaft 33 passes through the second connecting block 32, and the threaded section 333 of the rotating shaft 33 can be rotatably passed through the first connecting block 31 after passing through, and is screwed to the connecting head 35, so that the connecting plate 11 is clamped between the first connecting block 31 and the connecting head 35, and the stopper 332 abuts against the inner side of the second connecting block 32.

[0030] That is, when assembling the rotating shaft 33, the second connecting block 32 and the first connecting block 31, the second connecting block 32 can be first connected to the lamp post 20, then the first connecting block 31 is connected to the lamp head 10. Then, the threaded section 333 of the rotating shaft 33 can pass through the second connecting block 32 on the lamp post 20, and then pass through the first connecting block 31 and be screwed into the connecting head 35 inside the lamp head 10. At this time, the limiting head 332 at one end of the rotating shaft 33 abuts against the inner side of the second connecting block 32, and the other end of the rotating shaft 33 is abutted by the connecting head 35 and the connecting plate 11 of the lamp head 10. The assembly structure is stable and the disassembly and assembly are convenient.

[0031] Further, a first damping gasket 36 is clamped between the outer sides of the second connecting block 32 and the first connecting block 31, and a second damping gasket 37 is clamped between the inner side of the first connecting block 31 and the connecting head 35. In this way, the damping force can be increased between the first connecting block 31 and the second connecting block 32, and at the same time, the damping force can be increased between the first connecting block 31 and the connecting plate 11 of the lamp head 10. Only when the user operates to rotate the lamp head 10 can the lighting angle of the lamp head 10 be adjusted, preventing the lamp head 10 from falling under its own gravity.

[0032] Further, the above-mentioned limiting piece 34 is sleeved outside the rotating shaft 33 and is located between the first damping gasket and the first connecting block 31, which is convenient for the assembly of the limiting piece 34 and the rotating shaft 33.

[0033] Further, in order to facilitate the assembly of the first connecting block 31 and the lamp head 10, a first installation groove 12 is provided on the connecting plate 11, and the first connecting block 31 is embedded in the first installation groove 12. In this way, the positioning assembly of the first connecting block 31 and the lamp head 10 can be realized, and it can prevent the first connecting block 31 from protruding from the lamp head 10 and affecting the appearance.

[0034] Further, a first flat surface 334 can be provided on the outer surface of the rotating shaft 33, a connecting hole 321 is provided on the second connecting block 32, and a second flat surface 322 is provided on the inner wall of the connecting hole 321. When the rotating shaft 33 passes through the second connecting block 32, the rotating shaft 33 can be partially inserted into the connecting hole 321, and the first flat surface 334 and the second flat surface 322 abut against each other to prevent the rotating shaft 33 from rotating with the second connecting block 32, and the assembly structure is stable.

[0035] Further, a second installation groove 21 can be provided on the lamp post 20. When assembling the second connecting block 32 and the lamp post 20, the second connecting block 32 is embedded in the second installation groove 21; the connecting hole 321 is provided in the second installation groove 21. In this way, the positioning assembly of the second connecting block 32 and the lamp post 20 can be realized, and it can prevent the second connecting block 32 from protruding from the lamp post 20 and affecting the appearance.

[0036] Further, the first connecting block 31 and the second connecting block 32 are arranged in a vertical state, which is suitable for the rotatable assembly of the lamp head 10 and the lamp pole 20 of the "7"-shaped table lamp on the existing market.

[0037] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present utility model.
