DETAILED DESCRIPTION

[0027] 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.

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.

[0029] 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.

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.

[0030] like Figure 1 and Figure 2 As shown, the support structure according to the embodiment of the present application includes a base 10 and a support seat 20.

[0031] Specifically, a first limiting member 11 is provided on the base 10, a first wiring channel 101 is provided inside the base 10, and a first connecting port is provided in the first wiring channel 101; the support seat 20 is rotatably provided on the base 10, a movable second limiting member 21 is provided on the support seat 20, the second limiting member 21 can be moved to a locking position engaged with the first limiting member 11 and an unlocking position spaced from the first limiting member 11; when the second limiting member 21 is in the locking position, the support seat 20 cannot be rotated; when the second limiting member 21 is in the unlocking position, the support seat 20 can be rotated; a second wiring channel 201 is provided inside the support seat 20, and a second connecting port is provided in the second wiring channel 201; the first connecting port and the second connecting port are connected for the wire to pass through.

[0032] In detail, the support seat 20 is used to install the lamp body. The lighting range of the lamp body can be adjusted by adjusting the rotation angle of the support seat 20 relative to the base 10. By setting the first wiring channel 101, the second wiring channel 201 and configuring the first wiring channel 101 and the second wiring channel 201 to be connected, the wires can be routed through the first wiring channel 101 and the second wiring channel 201, thereby realizing the internal insertion of the wires, wherein the wires are used to connect the lamp body and the power supply. When the second limit member 21 moves to a position engaged with the first limit member 11, the second limit member 21 is limited by the first limit member 11, so that the support seat 20 is limited and cannot move, thereby allowing the support seat 20 to be locked at the angle required by the user. When the support seat 20 needs to be adjusted, only the second limit member 21 needs to be moved to disengage the second limit member 21 from the first limit member 11, thereby rotating the support seat 20.

[0033] According to the support structure of the embodiment of the present application, it is possible to achieve that the routing of the built-in wires is not affected when the support seat 20 is rotated or locked relative to the fixed seat, thereby realizing the internalization of the wires and improving the overall simplicity and safety of the support structure.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, the second limit member 21 is movable along the first direction, the rotation axis of the support seat 20 is parallel to the first direction, the support seat 20 includes a first support arm 22 and a second support arm 23, the first support arm 22 is provided with a second limit member 21 and a rotatable locking member 24, the locking member 24 and the second limit member 21 are movably connected, the locking member 24 is provided with a screw, the screw extends along the first direction, the base 10 is provided with a threaded hole, and the screw and the threaded hole cooperate.

[0035] In detail, the locking member 24 cooperates with the threaded hole through a screw, and the second limit member 21 is movably connected to the locking member 24, that is, when the locking member 24 rotates, the second limit member 21 does not rotate, but when it moves along the first direction by rotating the screw, the movement of the locking member 24 will drive the second limit member 21 to move along the first direction. In this way, the second limit member 21 can be moved in the first direction while ensuring that it does not deviate in the first direction by utilizing the cooperation of the screw and the threaded hole. The overall structural transmission setting is reasonable and reliable.

[0036] In a specific embodiment, when the second limit member 21 rotates with the support seat 20, the screw remains stationary. For example, a guide rod is provided on the first support arm 22, and a guide hole is provided on the second limit member 21. The guide rod is inserted into the guide hole and extends along the first direction. In this way, when the second limit member 21 moves along the first direction, the guide rod plays a guiding role, and the guide rod and the guide hole move relative to each other. When the support seat 20 rotates, the guide rod will drive the second limit member 21 to rotate together.

[0037] In a specific embodiment, during the rotation of the support base 20 , the second limiting member 21 and the screw rod remain stationary.

[0038] like Figure 2 As shown, in some embodiments, the threaded hole is provided on the first limiting member 11, the second limiting member 21 is sleeved on the locking member 24, the locking member 24 is provided with a first stop portion 241 and a second stop portion 242, and the first stop portion 241 and the second stop portion 242 are respectively located on both sides of the second limiting member 21.

[0039] Specifically, the threaded hole is provided on the first limiting member 11, and the second limiting member 21 is sleeved on the locking member 24. In the process that the second limiting member 21 rotates with the support seat 20, the locking member 24 rotates relative to the second limiting member 21 (that is, the second limiting member 21 rotates while the locking member 24 remains stationary) or the support seat 20 rotates while the second limiting member 21 remains stationary (this is another embodiment), and the locking member 24 is provided with a first stop portion 241 and a second stop portion 242, and the first stop portion 241 and the second stop portion 242 are respectively located at On both sides of the second limiter 21, in this way, when the moving direction of the locking member 24 along the first direction is changed, the first stopper 241 or the second stopper 242 can be used to drive the second limiter 21 to move along the first direction. For example, as shown in the figure, when the locking member 24 moves to the left, the first stopper 241 pushes the second limiter 21 to move the second limiter 21 in the first direction, and when the locking member 24 moves to the right, the second stopper 242 pushes the second limiter 21 to move the second limiter 21 in the first direction. In this way, the structural setting can be simplified, and the manufacturing difficulty and assembly difficulty can be reduced.

[0040] like Figure 2 As shown, in some embodiments, the second stop portion 242 is located on a side of the second limiting member 21 close to the first limiting member 11, and the second stop portion 242 is configured as an elastic member 25, and both ends of the elastic member 25 stop on the first limiting member 11 and the second limiting member 21 respectively.

[0041] In detail, the second stop portion 242 is located on the side of the second limit member 21 close to the first limit member 11, and the second stop portion 242 is configured as an elastic member 25. In this way, when the first stop portion 241 drives the second limit member 21 to gradually approach the first limit member 11, the elastic member 25 is gradually compressed until the second limit member 21 is engaged with the first limit member 11. When the screw rotates and drives the first stop portion 241 to gradually move away from the first limit member 11, the restoring force of the elastic member 25 will push the second limit member 21, driving the second limit member 21 to separate from the first limit member 11. Since it is necessary to ensure that the second limit member 21 and the locking member 24 can be assembled during processing and assembly, a certain gap will be reserved. At the same time, after the second limit member 21 is sleeved on the locking member 24, the second limit member 21 needs to be stopped on both sides. For this purpose, one of the first stop portion and the second stop portion must be movable or deformable so that it can meet the requirements of being able to avoid when installing the second limit member 21 and being able to play a pushing role after being assembled on the supporting structure. Therefore, the elastic member 25 is selected based on the above considerations to offset the assembly gap and ensure that the second limit member 21 is away from the first limit member 11 when necessary.

[0042] like Figure 2 As shown, in some embodiments, a first circular hole is provided on the first support arm 22, the second limiting member 21 includes a circular shaft, the circular shaft and the locking member 24 are passed through the first circular hole, a first limiting groove is provided on the locking member 24, and a second limiting groove is provided on the second limiting member 21. A fastener 50 is passed through both the first limiting groove and the second limiting groove, and the extension direction of the fastener 50 is perpendicular to the first direction.

[0043] To elaborate, a first circular hole is provided on the first support arm 22, and the second limit member 21 includes a circular shaft. The circular shaft sleeve 30 is provided on the locking member 24, and the circular shaft is also passed through the first circular hole. In this way, the rotation axis of the first support arm 22 is colinear with the axis of the circular hole, which can simplify the structural setting and functional positioning. A fastener 50 is commonly passed through the first limit groove and the second limit groove, and the fastener 50 can be used to limit the relative rotation of the second limit member 21 and the locking member 24. In this way, during the rotation of the support seat 20, the second limit member 21 remains stationary. In this way, the structural setting of the first limit member 11 and the second limit member 21 is simplified, ensuring that the first limit member 11 and the second limit member 21 only need to ensure that they can be engaged when translated in the first direction (if the second limit member 21 is rotatable, it is also necessary to ensure that the second limit member 21 can still be engaged with the first limit member 11 after rotating through a certain angle).

[0044] like Figure 2 As shown, in some embodiments, the first support arm 22 is provided with an avoidance hole 221, which extends in the radial direction of the first circular hole, and the avoidance hole 221 communicates with the second limiting groove and the outside.

[0045] In detail, the first support arm 22 is provided with an avoidance hole 221, which extends in the radial direction of the first circular hole, and the avoidance hole 221 connects the second limiting groove and the outside, so that it is convenient for the fastener 50 to extend from the outside into the avoidance hole 221 and then into the first limiting groove and the second limiting groove. The avoidance hole 221 is provided to simplify the assembly and disassembly of the structure. Therefore, the diameter and cross-sectional shape of the avoidance hole 221 are not limited in this application, and can be, for example, circular, square, and triangular.

[0046] According to the support structure of the embodiment of the present application, a first gear portion is provided on the side of the first limiting member 11 facing the second limiting member 21, and a second gear portion is provided on the side of the second limiting member 21 facing the first limiting member 11. When the first limiting member 11 and the second limiting member 21 are engaged, the first gear portion and the second gear portion are meshed.

[0047] It can be understood that the first limit member 11 and the second limit member 21 are configured to be engaged with each other by the gear parts, which can increase the engagement area between each other, further ensure that the friction force and the blocking force are sufficient to hinder the rotation of the support seat 20, improve the safety and reliability of the support seat 20 when locked, and at the same time extend the service life of the support structure.

[0048] like Figure 2As shown, in some embodiments, the first limit member 11 defines a first assembly hole, the first assembly hole defines a first connecting port, the second support arm 23 is provided with a second assembly hole, the second assembly hole defines a second connecting port, and the first assembly hole and the second assembly hole are jointly provided with a sleeve 30, and the sleeve 30 connects the first wiring channel 101 and the second wiring channel 201.

[0049] In detail, the use of the sleeve 30 to connect the second support arm 23 and the first limiter 11 can protect the wire and prevent the wire from being worn by twisted wires and gaps when the support base 20 rotates, thereby increasing the service life of the wire.

[0050] like Figure 2 As shown, in some embodiments, an elastic gasket 40 is sandwiched between the shaft sleeve 30 and the first limiting member 11 .

[0051] Specifically, the compressible property of the elastic gasket 40 is utilized to ensure that the elastic gasket 40 is fully compressed between the sleeve 30 and the first limit member 11, thereby increasing the friction between the sleeve 30 and the first limit member 11, thereby ensuring that the sleeve 30 remains stationary during the rotation of the support seat 20, so that the wire is not affected.

[0052] The lamp stand according to the embodiment of the present application includes the above-mentioned supporting structure.

[0053] According to the lamp stand of the embodiment of the present application, the support structure can achieve that the routing of the built-in wires is not affected when the support seat 20 is rotated or locked relative to the fixed seat, thereby realizing the internalization of the wires and improving the overall simplicity and safety of the lamp stand.
