Description

Technical Field

[0001] The utility model belongs to the technical field of lamp manufacturing, and particularly relates to a lamp with dead - angle - free multi - angle rotation. Background Art

[0002] With the improvement of people's living standards, the requirements for the lighting effect of lamps are getting higher and higher. People are no longer limited to the single - direction lighting of lamps and pursue lamps that can rotate in multiple directions for lighting. Therefore, many rotatable lamps have emerged on the market. However, in order to prevent the internal wires of the existing rotatable lamps on the market from continuously winding and twisting into a single strand and finally breaking due to the lamp always rotating in the same direction, a limiting structure is generally set on the lamp to limit the lamp from always rotating in the same direction. But this will also limit the rotation angle of the lamp. At least the lamp cannot rotate to the position where the limiting structure is set for lighting, resulting in dead - angle positions and unable to meet the lighting requirements of users. Summary of the Utility Model

[0003] (1) Purpose of the Utility Model

[0004] In order to overcome the above - mentioned deficiencies, the purpose of the present utility model is to provide a lamp with dead - angle - free multi - angle rotation, so as to solve the technical problem that the lighting angle of the existing rotatable lamps has dead - angle positions and cannot meet the lighting requirements of users.

[0005] (2) Technical Solution

[0006] To achieve the above purpose, the technical solution provided by this application is as follows:

[0007] A lamp with dead - angle - free multi - angle rotation includes: a mounting base with a hollow structure inside, a lamp body, a rotating shaft provided thereon with an upper end extending into the mounting base and capable of rotating relative to the mounting base. The rotating shaft is of a cylindrical structure and a limiting surface is formed on the side surface. A first limiting ring has a circular hole in the middle for sleeving on the upper end of the rotating shaft. The edge of the first limiting ring protrudes outward to form a first limiting portion, which can rotate with the rotating shaft and stop rotating after the first limiting portion abuts against the inner side surface of the mounting base. A limiting post is arranged on the upper end surface of the first limiting ring. A second limiting ring is arranged above the first limiting ring. The second limiting ring has a limiting hole in the middle that matches the shape of the limiting surface of the rotating shaft and is sleeved on the upper end of the rotating shaft. The edge of the second limiting ring protrudes outward to form a second limiting portion, which can continue to rotate with the rotating shaft after the first limiting ring stops rotating until the second limiting portion abuts against the limiting post and then stops rotating;

[0008] In this application, by providing a first limiting ring and a second limiting ring, a limiting surface is provided on the side surface of the rotating shaft, and a limiting post is provided on the upper end surface of the first limiting ring. The central hole positions of the first limiting ring and the second limiting ring are respectively designed. The central hole of the first limiting ring is set as a circular hole, and the central hole of the second limiting ring is set as a limiting hole matching the shape of the limiting surface of the rotating shaft. In this way, when the lamp body rotates counterclockwise, the rotating shaft, the first limiting ring, the second limiting ring, and the limiting post all rotate synchronously. When the first limiting part of the first limiting ring rotates to the position where it abuts against the inner side surface of the mounting seat, the first limiting ring stops rotating and a dead angle appears. Since the shape of the rotating shaft and the central hole of the first limiting ring are both circular, the rotating shaft and the second limiting ring can still rotate relative to the first limiting ring to cover the dead angle position until the second limiting part of the second limiting ring rotates to the position where it abuts against the limiting post and stops. At this time, the lamp body has rotated the first angle. When the lamp body rotates clockwise, its operating principle is the same as that of the counterclockwise rotation but in the opposite direction. The lamp body can also cover the dead angle position when rotating clockwise and the lamp body has rotated the second angle. The sum of the first angle and the second angle is greater than 360 degrees. Therefore, rotating the lamp body counterclockwise and clockwise can achieve dead-angle-free illumination.

[0009] In some embodiments, the limiting post is provided on the first limiting part;

[0010] By providing the limiting post on the first limiting part, the rotation angle of the lamp body is the same when it rotates counterclockwise or clockwise.

[0011] In some embodiments, the lower end of the rotating shaft is rotationally connected to the lamp body. Among them, the lower end face of the rotating shaft forms a first inclined surface, and the lamp body deviates from the central position to form a second inclined surface that cooperates with the first inclined surface;

[0012] By setting the lower end of the rotating shaft to be rotatable with the lamp body, setting the lower end of the rotating shaft as the first inclined surface, and respectively setting the second inclined surface at the position where the lamp body deviates from the central position, rotating the lamp body relative to the rotating shaft can make the lamp body illuminate obliquely upward or obliquely downward, further expanding the illumination angle of the lamp body.

[0013] In some embodiments, rotating gaskets are respectively provided between the lamp body and the outer end face of the mounting seat, between the first limiting ring and the inner end face of the mounting seat, and between the first and second limiting rings;

[0014] By providing the rotating gaskets, it is beneficial to reduce the friction between the rotating shaft and the mounting seat, between the first limiting ring and the mounting seat, and between the first and second limiting rings, thereby improving the smoothness during rotation.

[0015] In some embodiments, it further includes a locking member sleeved on the upper end of the rotating shaft and located above the second limiting ring for limiting the position of the second limiting ring on the rotating shaft;

[0016] The locking member is provided to limit the first and second limiting rings, preventing the first and second limiting rings from disengaging from the rotating shaft.

[0017] In some embodiments, the outer shell of the lamp body is made of a metal material;

[0018] The outer shell made of metal material is conducive to rapid heat dissipation. Description of the Drawings

[0029] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0030] A non-dead-angle multi-angle rotating lamp provided by the present utility model includes: a mounting base 1 with a hollow structure inside, a lamp body 2, a rotating shaft 3 disposed thereon and extending into the mounting base 1 and capable of rotating relative to the mounting base 1. The rotating shaft 3 is of a cylindrical structure and has a limiting surface 302 on its side. A first limiting ring 4 has a circular hole 402 formed in the middle and sleeved on the upper end of the rotating shaft 3. The edge of the first limiting ring 4 protrudes outward to form a first limiting portion 401. The first limiting ring 4 can rotate with the rotating shaft 3 and stops rotating after the first limiting portion 401 abuts against the inner side surface of the mounting base 1. A limiting post 7 is disposed on the upper end surface of the first limiting ring 4. A second limiting ring 5 is disposed above the first limiting ring 4. The second limiting ring 5 has a limiting hole 502 formed in the middle and sleeved on the upper end of the rotating shaft 3, and the shape of the limiting hole 502 matches that of the limiting surface 302 of the rotating shaft 3. The edge of the second limiting ring 5 protrudes outward to form a second limiting portion 501, and can continue to rotate with the rotating shaft 3 until the second limiting portion 501 abuts against the limiting post 7 and stops rotating after the first limiting ring 4 rotates to the position where the first limiting portion 401 abuts against the inner side surface of the mounting base 1 and stops rotating.

[0031] Specifically, the limiting surface 302 is two horizontal planes.

[0032] Specifically, the lamp body 2 is connected to the rotating shaft 3, and when the lamp body 2 rotates, the rotating shaft 3 rotates accordingly.

[0033] Please refer to Figure 6 , specifically, taking the limiting post 7 being disposed on the first limiting portion 401, the first limiting portion 401 of the first limiting ring 4 being parallel to the horizontal line L1, the second limiting portion 501 of the second limiting ring 5 being parallel to the horizontal line L1, and the first limiting portion 401 and the second limiting portion 501 being in opposite directions as the initial state, the rotation action of the lamp body 2 will be introduced:

[0034] Please refer to Figure 7, the lamp body 2 rotates counterclockwise. When the first limiting part 401 of the first limiting ring 4 rotates to the position where it abuts against the inner side surface of the mounting base 1, the first limiting ring 4 stops rotating. Since the shape of the rotating shaft 3 and the central hole of the first limiting ring 4 are both circular, after the first limiting ring 4 stops rotating, the rotating shaft 3 and the second limiting ring 5 can still rotate relative to the first limiting ring 4 until the second limiting part 501 of the second limiting ring 5 rotates to the position where it abuts against the limiting column 7 and then stops rotating. At this time, the lamp body 2 has rotated a first angle ɑ1 in total and reaches the position of the straight line L2, which is above the horizontal line L1;

[0035] Please refer to Figure 8 , the lamp body 2 rotates clockwise. When the first limiting part 401 of the first limiting ring 4 rotates to the position where it abuts against the inner side surface of the mounting base 1, the first limiting ring 4 stops rotating. Since the shape of the rotating shaft 3 and the central hole of the first limiting ring 4 are both circular, after the first limiting ring 4 stops rotating, the rotating shaft 3 and the second limiting ring 5 can still rotate relative to the first limiting ring 4 until the second limiting part 501 of the second limiting ring 5 rotates to the position where it abuts against the limiting column 7 and then stops rotating. At this time, the lamp body 2 has rotated a second angle ɑ2 in total and reaches the position of the straight line L3, which is below the horizontal line L1;

[0036] The sum of the first angle ɑ1 and the second angle ɑ2 exceeds 360 degrees, and the lamp body 2 can achieve multi-angle lighting without dead angles.

[0037] Specifically, the limiting column 7 can be arranged at different positions on the upper end face of the first limiting ring 4, and the lamp body 2 can also achieve multi-angle lighting without dead angles.

[0038] Preferably, arranging the limiting column 7 on the first limiting part 401 can ensure that the rotation angles of the lamp body 2 in the counterclockwise or clockwise direction are the same.

[0039] Preferably, the lower end of the rotating shaft 3 is rotationally connected to the lamp body 2. Among them, a first inclined surface 301 is formed on the lower end face of the rotating shaft 3, and the lamp body 2 deviates from the central position to form a second inclined surface 201 that cooperates with the first inclined surface 301. When the lamp body 2 is rotated, the lamp body 2 can illuminate obliquely upward or obliquely downward.

[0040] Preferably, rotating gaskets 8 are respectively arranged between the outer end face of the lamp body 2 and the mounting base 1, between the inner end face of the first limiting ring 4 and the mounting base 1, and between the first limiting ring 4 and the second limiting ring 5. The rotating gaskets 8 can be made of metal and are sprayed with lubricating oil on the surface.

[0041] Preferably, a locking member 6 is sleeved on the upper end of the rotating shaft 3. The locking member 6 can be a nut and is used to limit the position of the second limiting ring 5 on the rotating shaft 3.

[0042] Preferably, the outer shell of the lamp body 2 of the present application is made of a metal material, which can achieve rapid heat dissipation.
