[0028] like Figure 1 Shown to Figure 5 As shown, in the first aspect, the present embodiment provides a movable lamp stand, which includes a shell 1, a connecting bracket 2 and a mounting ring 3; the connecting bracket 2 includes a first connecting part 21 and a second connecting part 22, the first connecting part 21 is movably connected to the inner wall of the shell 1 and supports the second connecting part 22, and a first sliding groove 222 is provided on the inner wall of the second connecting part 22, and a straight track is provided in the first sliding groove 222 for sliding connection with the mounting ring 3; a first through hole 31 is provided on the outer wall of the mounting ring 3, and a first roller 312 provided in the first through hole 31 is slidably connected to the first sliding groove 222.

[0029] In actual usage scenarios, the movable lamp stand is used to install the wick that generates light in the lamp. The movable lamp stand provides a flexible adjustment method for the user to adjust the light illumination line. This adjustment method is based on the movable connection structure of the mounting ring 3 and the connecting bracket 2 in the movable lamp stand. The movable connection between the mounting ring 3 and the connecting bracket 2 enables the mounting ring 3 and the connecting bracket 2 to be relatively displaced on a straight path, that is, the mounting ring 3 can be pushed and pulled straightly under the connection of the connecting bracket 2 to adjust the installation position. The connecting bracket 2 included in the lamp stand is designed with a connecting part for support and connection, and the connecting part is provided with a mounting groove or a mounting hole for movable connection, so that the connecting part can be movably connected to multiple components at the same time. Specifically, the connecting bracket 2 is arranged in the shell 1 and is connected to the inner wall of the shell 1. The connecting part includes a first connecting part 21 and a second connecting part 22. The first connecting part 21 is located on the lower side of the second connecting part 22 and supports the second connecting part 22. The first connecting part 21 The first roller 312 is provided on the outer wall surface of the mounting ring 3, and the mounting ring 3 is clamped in the first sliding groove 222 on the connecting bracket 2 to slide. The first roller 312 is provided on the outer wall surface of the mounting ring 3, and the mounting ring 3 is clamped in the first sliding groove 222 on the connecting bracket 2 to slide, so that the mounting ring 3 can be relatively displaced with the connecting bracket 2. Moreover, since the sliding track provided in the first sliding groove 222 is a straight track, the relative displacement path between the mounting ring 3 and the connecting bracket 2 is always kept in a straight state. In this relative displacement mode, the mounting ring 3 and the connecting bracket 2 do not deviate outside the straight path, and the controllability of the relative position is maintained.

[0030] In summary, by arranging a roller on the mounting ring 3 and making it slide straight in the sliding groove of the connecting bracket 2, the mounting ring 3 and the connecting bracket 2 of the movable lamp stand can achieve relative displacement in a straight path, avoiding the problem of excessive blind area in light line adjustment caused by the fact that the mounting ring 3 and the connecting bracket 2 in the traditional lamp stand are only designed with a relative rotation connection structure. The user can adjust the light line in a straight movement according to actual use needs, refine the adjustment method of the light line, improve the efficiency of the light line adjustment process, and meet the user's more diverse lighting needs.

[0031] Furthermore, a second sliding groove 322 is provided on the side edge of the mounting ring 3 , a second through hole 23 is provided on the connecting bracket 2 , and a second roller 231 provided in the second through hole 23 is slidably connected to the second sliding groove 322 .

[0032] Specifically, a second sliding groove 322 is provided on the side edge of the mounting ring 3, and a second roller 231 is provided in the second through hole 23 provided on the connecting bracket 2, so that the second roller 231 is slidingly connected to the second sliding groove 322. At this time, the first roller 312 is in the first sliding groove 222, and the second roller 231 is in the second sliding groove 322, which together constitute a sliding connection structure between the mounting ring 3 and the connecting bracket 2. The first roller 312 and the second roller 231 slide on their respective sliding tracks at the same time. Such a sliding connection structure prevents the mounting ring 3 and the connecting bracket 2 from rotating uselessly, thereby improving the stability and efficiency of the displacement between the mounting ring 3 and the connecting bracket 2 along a straight path.

[0033] Furthermore, the interior of the shell 1 is hollow to form an installation space for installing the connecting bracket 2. The shell 1 is sleeved on the outside of the connecting bracket 2, and the connecting bracket 2 is arranged inside the shell 1. The first connecting portion 21 is movably connected to the shell 1.

[0034] Specifically, the three main components of the movable lamp stand, namely the shell 1, the connecting bracket 2 and the mounting ring 3, are movably connected in the form of layered sockets, making full use of the internal installation space formed after the components are connected, making the installation and movable adjustment of the lamp stand easier, and also conducive to forming the travel route of the lighting light and optimizing the lighting effect.

[0035] Furthermore, a third sliding groove 210 is provided on the first connecting portion 21 , a third through hole 33 is provided on the housing 1 , and a third roller 331 provided in the third through hole 33 is slidably connected to the third sliding groove 210 .

[0036] Specifically, the sliding connection between the third roller 331 and the third sliding groove 210 enhances the connection stability between the housing 1 and the connecting bracket 2 .

[0037] Furthermore, the first connecting portion 21 includes a first connecting leg 211 and a second connecting leg 212. The first connecting leg 211 and the second connecting leg 212 are respectively provided with a rotating through hole 5. The rotating through hole 5 is arranged opposite to the third through hole 33 and is penetrated by a movable connecting member, which is used to control the rotation of the connecting bracket 2.

[0038] Specifically, the first connecting part 21 includes a first connecting leg 211 and a second connecting leg 212, which are movably connected to the side wall of the shell 1 by setting a rotating through hole 5 and passing through a movable connecting piece. The movable connecting piece can be used to control the movement of the first connecting part 21 so that the connecting bracket 2 and the shell 1 can rotate relative to each other. The first connecting leg 211 and the second connecting leg 212 are respectively movably connected to the side wall of the shell 1, and the first connecting leg 211 and the second connecting leg 212 can be set at two opposite points on the side wall of the shell 1 so that the rotating through holes 5 set on the first connecting leg 211 and the second connecting leg 212 are opposite. Such a design can optimize the connection relationship between the connecting bracket 2 and the shell 1, make the relative position of the connecting bracket 2 and the shell 1 easier to adjust, and also enhance the stability of the overall structure after the connecting bracket 2 is connected to the shell 1.

[0039] Furthermore, the side wall of the mounting ring 3 is a curved surface, and the side wall of the housing 1 is provided with an arc-shaped recessed edge, which fits the side wall of the mounting ring 3 .

[0040] Specifically, after the mounting ring 3 is connected to the connecting bracket 2, it can rotate relative to the shell 1 under the movable connection of the connecting parts. At this time, the main part of the connecting bracket 2 is arranged in the installation space of the shell 1, and a recessed edge is provided on the side wall of the shell 1, so that the installation space inside the shell 1 is connected to the outside of the shell 1 from the side wall. During the rotation, the connecting bracket 2 and the mounting ring 3 can move to the outside of the shell 1 through the space above the arc-shaped recessed edge. When the arc-shaped recessed edge is in contact with the arc-shaped side wall of the mounting ring 3, the mounting ring 3 and the connecting bracket 2 complete the position adjustment and stop rotating.

[0041] Furthermore, a tooth row is provided on the third sliding groove 210 , and the tooth row is used for movably engaging with the third roller 331 .

[0042] Specifically, a tooth row is provided on the wall surface of the sliding track formed in the third sliding groove 210, and the tooth row includes a plurality of regularly arranged latching teeth. After the third roller 331 is engaged with the third sliding groove 210, it slides along the sliding track formed in the third sliding groove 210. The circumferential side wall of the third roller 331 is in direct contact with the latching teeth of the tooth row. The continuously arranged latching teeth form regularly undulating protrusions and depressions, so that the sliding of the third roller 331 in the sliding track is adjustable. More specifically, after the mounting ring 3 and the connecting bracket 2 are connected, the mounting ring 3 and the connecting bracket 2 can simultaneously rotate relative to the shell 1, and the third sliding groove 210 serves as a connection between the connecting bracket 2 and the shell 1. The connecting component has a sliding track with a certain curvature, so that the relative rotation between the connecting bracket 2 and the shell 1 can be completed under the cooperation of the curvature of the sliding track. The teeth on the third sliding groove 210 have a certain beneficial resistance to the third roller 331, preventing the third roller 331 from sliding uncontrollably in the sliding track. When the third roller 331 slides through each tooth, the connecting bracket 2 and the shell 1 can complete a relative rotation with a certain angle. In addition, the sound emitted by the collision between the tooth and the third roller 331 is fed back to the user, which can be used as a basis for the user to judge whether the rotation is successful or not, making the activity adjustment process of the movable lamp stand more accurate.

[0043] Furthermore, a guide member is provided on the inner wall surface of the connecting bracket 2 , and a guide slope 4 is provided on the upper end of the guide member. The first roller 312 slides into the first sliding groove 222 through the guide slope 4 .

[0044] Specifically, the installation method of the mounting ring 3 and the connecting bracket 2 is a snap-fitting movable connection. The mounting ring 3 is connected to the connecting bracket 2 from the top of the connecting bracket 2 downward, so that the outer wall of the mounting ring 3 contacts the inner wall of the connecting bracket 2. The component for snapping provided on the mounting ring 3 contacts the component for snapping provided on the connecting bracket 2 and completes the snapping under the action of force. More specifically, the guide member provided on the inner wall of the connecting bracket 2 serves as a guide member of the first sliding groove 222, and guides the first roller 312 into the first sliding groove 222 for sliding. A guide slope 4 is provided on the upper end of the guide member, and the first roller 312 slides into the first sliding groove 222 through the guide slope 4 to complete the snapping. The guide member improves the connection efficiency between the mounting ring 3 and the connecting bracket 2, and avoids the problem that the mounting ring 3 and the connecting bracket 2 cannot be snapped due to deformation caused by external reasons.

[0045] Furthermore, a reflector is provided on the inner wall surface of the mounting ring 3 for adjusting the light path.

[0046] Specifically, the mounting ring 3 can adjust its position by relative movement with the connecting bracket 2, and can also adjust its position together with the connecting bracket 2 and the shell 1. The mounting ring 3 has flexible position adjustment structural conditions. The wick is installed in the shell 1 to generate light. The lighting circuit is close to the inner wall of the mounting ring 3 and is led out of the lamp holder through the upper opening of the mounting ring 3. The mounting ring 3 becomes an important component that affects the progress of the lighting circuit. Existing lamp holders often adopt methods such as built-in reflectors, which use the principle of light reflection or refraction to intervene in the travel route of the light to achieve the purpose of lighting for the user. A reflector with light reflecting function is provided on the mounting ring 3, so that the reflector can translate and rotate with the mounting ring 3 and the connecting bracket 2, thereby optimizing the implementation effect of the light reflection function of the reflector and making the adjustment of the lighting function of the reflector more flexible.

[0047] In a second aspect, an embodiment of the present invention discloses a lamp comprising a wick and the above-mentioned movable lamp holder, wherein the wick is installed in the installation space of the shell 1 and generates lighting light, and the travel path of the lighting light passes through the installation space and is guided out of the lamp holder through the opening of the installation ring 3.

[0048] like Figure 6 As shown, the present invention discloses a lamp and a movable lamp stand thereof, comprising a housing 1, a connecting bracket 2 and a mounting ring 3; the connecting bracket 2 comprises a first connecting portion 21 and a second connecting portion 22, the first connecting portion 21 is movably connected to the inner wall of the housing 1 and supports the second connecting portion 22, a first sliding groove 222 is provided on the inner wall of the second connecting portion 22, a straight track is provided in the first sliding groove 222 for sliding connection with the mounting ring 3; a first through hole 31 is provided on the outer wall of the mounting ring 3, a first roller 312 provided in the first through hole 31 slides with the first sliding groove 222 Dynamic connection, the lamp holder is provided with a roller on the mounting ring 3 and makes it slide straightly in the sliding groove of the connecting bracket 2. The mounting ring 3 and the connecting bracket 2 of the movable lamp holder can realize relative displacement in a straight path, avoiding the problem of excessive blind area of light line adjustment caused by the relative rotation connection structure only being designed between the mounting ring 3 and the connecting bracket 2 in the traditional lamp holder. The user can adjust the light line in a straight movement according to actual use needs, refine the adjustment method of the light line, improve the efficiency of the light line adjustment process, and meet the user's more diverse lighting needs.

[0049] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
