[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0033] like Figure 1-Figure 3 As shown, the lamp stand according to the embodiment of the present application includes a base 10 and a support frame 20 arranged on the base 10, the support frame 20 is used to install the light source structure, the base 10 includes a locking assembly 11, a first adapter 12 and a plurality of leg tubes 13, each leg tube 13 is rotatably connected to the first adapter 12 respectively, the locking assembly 11 is connected to the first adapter 12 and the leg tube 13 at the same time, the working end of the locking assembly 11 is movable to unlock the leg tube 13 so that the leg tube 13 can rotate or lock the leg tube 13, the leg tube 13, the locking assembly 11 and the first adapter 12 are connected in sequence so that the wire can pass through.

[0034] Specifically, the base 10 is used to support the support frame 20, and the support frame 20 is used to install the light source structure. The leg tube 13 is rotatably connected to the first adapter 12, so that the leg tube 13 can be retracted or opened by rotating the leg tube 13. The locking assembly 11 simultaneously connects the first adapter 12 and the leg tube 13. When the lamp holder needs to be used, the leg tube 13 can be unlocked by moving (including at least one of translation and rotation) the working end of the locking assembly 11. When the leg tube 13 is opened, the leg tube 13 can be locked by moving (including at least one of translation and rotation) the working end of the locking assembly 11, so that the leg tube 13 can be fixed in the opened position, which can make the base 10 more stable, and the leg tube 13 can be unlocked by moving (including at least one of translation and rotation) the working end of the locking assembly 11, so that when the lamp holder is not needed, the leg tube 13 can be rotated to retract the leg tube 13, which can reduce the overall volume of the lamp holder.

[0035] According to the lamp stand in the embodiment of the present application, the leg 13 can be locked or unlocked by moving the working end of the locking assembly 11. When the leg 13 is unlocked, it can be rotated to a desired position at a desired angle. After being rotated to the desired position, the leg 13 can be locked to be fixed. The operation is simple and the structure is simple, which greatly improves the convenience of use of the lamp stand.

[0036] like Figure 3 As shown, according to the lamp holder of the embodiment of the present application, the locking assembly 11 includes a locking member 111 and a first reset member 112 abutting against the locking member 111, the working end of the locking assembly 11 is configured as the locking member 111, the locking member 111 is movable between a first position and a second position, the leg 13 is rotatable when the locking member 111 is in the first position, and the leg 13 is locked when the locking member 111 is in the second position, and the first reset member 112 is used to provide a force for the locking member 111 so that the locking member 111 is always kept in the second position.

[0037] In detail, the first reset member 112 is used to provide a force for the locking member 111 so that the locking member 111 is always kept in the second position. When the locking member 111 needs to be moved to unlock the leg tube 13, a force needs to be applied to the locking member 111 to overcome the force applied by the first reset member 112 to the locking member 111, thereby pushing the locking member 111 to move from the second position to the first position, so that the leg tube 13 can be unlocked and rotated to the desired position according to user needs. After the leg tube 13 rotates to the corresponding position, the locking member 111 stops being pressed. The stop member 111 applies a force, and the first reset member 112 resets and drives the locking member 111 to automatically move from the first position to the second position, thereby locking the leg tube 13. Such a configuration can simplify the operation process of the locking member 111. Only the locking member 111 needs to be operated when unlocking, and the first reset member 112 will automatically reset the locking member 111 to keep the leg tube 13 locked in a normal state, thereby making the base 10 more reliable during operation and preventing the leg tube 13 from being unlocked by accident and causing the entire lamp stand to be unstable.

[0038] The force applied to the locking member 111 may be driven by a power mechanism or manually; the first reset member 112 may be rubber, silicone, or a spring, etc. Usually, the first reset member 112 is selected as a spring, but this is not limited in the present application.

[0039] like Figure 3As shown, in some embodiments, the locking member 111 includes a plurality of limiting portions 1111, and a plurality of grooves 131 are provided on the leg tube 13. The limiting portions 1111 correspond to the grooves 131 one by one and are arranged relatively to each other. When the locking member 111 is in the second position, the limiting portions 1111 are stuck in the grooves 131, and when the locking member 111 is in the first position, the limiting portions 1111 are out of the grooves 131.

[0040] Specifically, the locking member 111 includes a plurality of limiting portions 1111, and a plurality of grooves 131 are provided on the leg tube 13. The limiting portions 1111 and the grooves 131 are matched one by one to realize locking and unlocking of the leg tube 13. For the convenience of description, for example, the number of the grooves 131 is two, and the two grooves 131 are defined as the first groove and the second groove, respectively. The number of the limiting portions 1111 is two, and the two limiting portions 1111 are defined as the first limiting portion and the second limiting portion, respectively. That is to say, when the first limiting portion is clamped in the first groove, the locking member 1111 is locked in the locking member 1111. In the groove, when the second limiting portion is clamped in the second groove 131, if the leg tube 13 wants to rotate, it cannot overcome the obstruction of the limiting portion 1111 to the groove 131, and thus cannot rotate to achieve locking. When the limiting portion 1111 is disengaged from the groove 131, the leg tube 13 drives the groove 131 to rotate. When the belt rotates to the corresponding position, the first limiting portion corresponds to the second groove and is clamped in the second groove, and the second limiting portion corresponds to the first groove and is clamped in the first groove, thereby achieving locking of the leg tube 13, thereby simplifying the overall structural setting of the lamp stand.

[0041] like Figure 3 As shown, in some embodiments, the locking assembly 11 also includes a guide rod 113 and a pressing piece 114, the pressing piece 114, the guide rod 113 and the locking piece 111 are abutted in sequence, the leg tube 13 includes a first connecting portion 132, the first adapter 12 includes a second connecting portion 121, the first connecting portion 132 and the second connecting portion 121 are simultaneously connected to the locking assembly 11, at least one of the first connecting portion 132 and the second connecting portion 121 is provided with a guide groove 1323, the guide rod 113 is inserted into the guide groove 1323, and the first connecting portion 132 is provided with a groove 131.

[0042] In detail, the locking assembly 11 also includes a guide rod 113 and a pressing piece 114. The pressing piece 114, the guide rod 113 and the locking piece 111 are abutted in sequence. When a force is applied to the pressing piece 114, the pressing force transfers the force to the guide rod 113, and the guide rod 113 transfers the force to the locking piece 111, thereby driving the locking piece 111. During resetting, the force applied to the pressing piece 114 disappears, and the locking piece 111 transfers the reset force received to the guide rod 113, and the guide rod 113 transfers the reset force to the pressing piece 114, thereby resetting the guide rod 113 and the pressing piece 114. During this process, the guide rod 113 can be positioned and limited by the guide groove 1323 through cooperation with the guide groove 1323, thereby ensuring reliability during the movement process. At the same time, such a setting can simplify the structural setting.

[0043] like Figure 3 , Figure 4 as well as Figure 6 As shown, in some embodiments, the first connection part 132 and the second connection part 121 are rotatably connected through the connecting member 14, the first connection part 132 is provided with a first connecting groove 1321, the second connection part 121 is provided with a second connecting groove 1223, and the connecting member 14 is provided with a third connecting groove 141. The first connecting groove 1321, the third connecting groove 141 and the second connecting groove 1223 are connected in sequence for the wire to pass through. Such an arrangement allows the wire to pass through the first connecting part 132, the second connecting part 121 and the connecting member 14 without affecting the rotation of the leg tube 13, thereby reasonably performing the structural layout.

[0044] like Figure 3 As shown, in some embodiments, the locking member 111 is located inside the second connecting portion 121 and is sleeved outside the connecting member 14 , and the first restoring member 112 is sleeved outside the connecting member 14 and is clamped between the locking member 111 and the inner wall of the second connecting portion 121 .

[0045] It is understandable that, with such a configuration, the connecting member 14 can be used to guide and limit the locking member 111 and the first reset member 112, thereby ensuring the position accuracy of the locking member 111 during movement and preventing the first reset member 112 from being deflected or stuck during compression and reset.

[0046] like Figure 3-Figure 5 As shown, in some embodiments, a partition 1322 is provided in the first connecting portion 132, the partition 1322 is arranged opposite to the connecting member 14 and spaced from each other to define a portion of the first connecting groove 1321, the pressing member 114 is movably provided on the partition 1322, and a second reset member 15 is sandwiched between the pressing member 114 and the partition 1322.

[0047] According to the lamp holder of the embodiment of the present application, the partition 1322 can be used to limit the pressing member 114. At the same time, in the process of the locking member 111 moving from the first position to the second position, the force of the second resetting member 15 can be used to ensure the accurate resetting of the pressing member 114. At the same time, the partition 1322 and the connecting member 14 are arranged relative to each other and spaced from each other to define a portion of the first connecting groove 1321. In this way, the spatial structure is reasonably arranged to allow the wires to pass through from the inside while ensuring that the wires will not be affected during the rotation of the leg tube 13 and the movement of the locking member 111.

[0048] The second pressing member 114 is configured as a spring.

[0049] like Figure 1 , Figure 5 and Figure 7 As shown, according to the lamp holder of the embodiment of the present application, the support frame 20 includes a mounting shell 21, a connecting rod 22 and a second adapter 23, the base 10, the mounting shell 21, the connecting rod 22 and the second adapter 23 are connected in sequence, a control main board 211 is installed in the mounting shell 21, the control main board 211 is electrically connected to the wire, the second adapter 23 is connected to the connecting rod 22 and is used to install the light source structure, the connecting rod 22 includes a plurality of rod body portions 221 that are movably connected in sequence, a conductive member 222 is fixed in each rod body portion 221, two adjacent conductive members 222 abut against each other, the conductive member 222 moves synchronously with the rod body portion 221, and the conductive member 222 electrically connects the light source structure and the control main board 211.

[0050] In detail, the wire passes through the first connecting groove 1321, the third connecting groove 141 and the second connecting groove 1223 in sequence and is finally electrically connected to the control main board 211 in the mounting shell 21. When the connecting rod 22 is extended, the corresponding conductive members 222 of at least two adjacent rod body parts 221 move in directions away from each other, and the misaligned parts thereof become longer, and the overlapping parts become shorter. When the connecting rod 22 is shortened, the corresponding conductive members 222 of at least two adjacent rod body parts 221 move in directions close to each other, and the misaligned parts thereof become shorter, and the overlapping parts become longer. This enables the adjacent conductive members 222 to change with the movement of the rod body parts 221, thereby adapting to the change in the overall length of the connecting rod 22. During this process, the conductive members 222 always maintain electrical conduction between the control main board 211 and the light source structure, thereby avoiding redundancy when the length of the conductive structure cannot be changed with the connecting rod 22.

[0051] In some specific embodiments, a row of conductive members 222 is provided in the connecting rod 22; in some specific embodiments, two rows of conductive members 222 are provided in the connecting rod 22, and the two rows of conductive members 222 are symmetrically arranged along the circumferential direction of the connecting rod 22; in some specific embodiments, three rows of conductive members 222 are provided in the connecting rod 22, and the three rows of conductive members 222 are arranged at intervals along the circumferential direction of the connecting rod 22.

[0052] In a specific embodiment, the cross-sectional shape of the conductive member 222 is an annular shape, and the conductive member 222 is arranged along the inner circumference direction of the rod body 221; in a specific embodiment, the cross-sectional shape of the conductive member 222 is an arc shape; in a specific embodiment, the cross-sectional shape of the conductive member 222 is a rectangular shape.

[0053] like Figure 7 and Figure 8 As shown, in some embodiments, the conductive member 222 includes a main body 223 and a clip portion 224 connected to the main body 223 , and any two adjacent conductive members 222 are defined as a first conductive member 222 and a second conductive member 222 , and the clip portion 224 of the first conductive member 222 stops on the main body 223 of the second conductive member 222 .

[0054] It can be understood that the conductive member 222 includes a main body 223 and a clamping portion 224 connected to the main body 223, and the clamping portion 224 of the first conductive member 222 stops on the main body 223 of the second conductive member 222, so that the electrical conduction between the first conductive member 222 and the second conductive member 222 can be achieved, that is, the electrical conduction between any two adjacent conductive members 222, wherein the first conductive member 222 and the second conductive member 222 are only described based on the convenience of describing the mechanical position relationship between any two adjacent conductive members 222, and are not limitations on the structure or function of the conductive member 222.

[0055] For example, the multiple conductive parts 222 are four conductive parts 222, and the four conductive parts 222 are arranged in sequence as a first conductive part, a second conductive part, a third conductive part, and a fourth conductive part. The main body 223 of the first conductive part is used to electrically connect to the power supply, the clamping part 224 of the first conductive part stops on the main body 223 of the second conductive part, the clamping part 224 of the second conductive part stops on the main body 223 of the third conductive part, the clamping part 224 of the third conductive part stops on the main body 223 of the fourth conductive part, and the main body 223 of the fourth conductive part is used to electrically connect to the light source structure.

[0056] like Figure 2As shown, in some embodiments, the light source structure is provided with a first plug connector, a plurality of first contacts are provided on the first plug connector, a second plug connector 24 is provided on the side of the second adapter 23 close to the light source structure, a plurality of second contacts 241 are provided on the second plug connector 24, the second contacts 241 are electrically connected to the conductive member 222, the light source structure and the second adapter 23 are snapped together, the first plug connector and the second plug connector 24 are plugged in and make the first contacts and the second contacts 241 abut one by one and electrically conductive.

[0057] In detail, the light source structure can be connected by snapping when installed on the second adapter 23, and can be easily disassembled. When the light source structure and the second adapter 23 are snapped, the first plug connector and the second plug connector 24 are plugged in and the first contact and the second contact 241 are abutted one by one and electrically conductive, so that the light source structure and the conductive member 222 can be electrically conductive, further simplifying the assembly and disassembly of the light source structure and the second adapter 23, thereby improving the convenience of user use.
