In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0045] In this article, it is necessary to explain that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0046] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0047] Reference Figures 1-8 For the first embodiment of the utility model, an adjustable lighting device is proposed, which comprises a base 1; a first folding rod 2 is rotatably arranged on the base 1; a second folding rod 3 is rotatably arranged at the other end of the first folding rod 2; a lighting device 4 is arranged at the other end of the second folding rod 3.

[0048] In this embodiment, in order to solve the problem that the mounting rod of the lighting device is long and occupies a large area in the related art, causing inconvenience in transportation, an adjustable lighting device is designed. The base 1 has a certain weight and stability, and its shape is circular, with anti-skid rubber pads at the bottom, which can be placed on a flat surface such as a table top and is not easy to slide. The first folding rod 2 is rotatably connected to the center position of the base 1 by a steel pin shaft 5 with a diameter of 5 mm. The second folding rod 3 is rotatably arranged at the first folding rod 2. The lighting device 4 selects a lamp panel composed of LED lamp beads with a power of 10 watts, which is installed at the other end of the second folding rod 3. The lamp panel is connected to the external power supply through wires, which can be arranged and fixed along the structure of the folding rod to avoid affecting the rotation of the folding rod.

[0049] The advantage is that the adjustable lighting device effectively solves the problem of long mounting rod and large area of traditional lighting device, which is inconvenient for transportation. In the transportation process, the first folding rod 2 and the second folding rod 3 can be folded and stored, greatly reducing the overall space occupation, and facilitating batch transportation and storage. At the same time, in use, the angle and length of the first folding rod 2 and the second folding rod 3 can be adjusted flexibly according to the actual lighting needs, realizing multi-directional and multi-angle irradiation of the lighting device 4 in three-dimensional space.

[0050] Further, it further comprises a pin shaft 5, the pin shaft 5 is arranged on the base 1, and the first folding rod 2 is rotatably arranged on the base 1 through the pin shaft 5; a limiting pin 6 is slidably arranged on the base 1, and after sliding, one end of the limiting pin 6 penetrates the base 1 and the first folding rod 2, which is used to limit the relative position between the base 1 and the first folding rod 2 together with the pin shaft 5.

[0051] In this embodiment, the pin shaft 5 penetrates the connecting part of the base 1 and the first folding rod 2. A through hole is processed on the base 1, and the limiting pin 6 can smoothly slide in the through hole. When the first folding rod 2 is rotated to the desired angle, the limiting pin 6 is pushed to slide in the through hole, so that it penetrates the base 1 and is inserted into the corresponding first folding rod 2, thereby fixing the first folding rod 2 at this position.

[0052] The advantage is that the combination of the pin shaft 5 and the limiting pin 6 provides a stable and reliable rotating connection and angle locking function between the first folding rod 2 and the base 1. On the one hand, the pin shaft 5 ensures the rigidity of the connection, so that the first folding rod 2 can withstand the weight of the lighting device 4 and a certain degree of external force without shaking or displacement during normal use. On the other hand, the sliding locking mechanism of the limiting pin 6 makes the angle adjustment of the first folding rod 2 precise and easy to operate.

[0053] Further, the first folding rod 2 has a positioning groove 201 at the end away from the base 1, and the second folding rod 3 abuts or does not abut the inner wall of the positioning groove 201 after being rotated.

[0054] Further, it also includes a hinge 7, and the two ends of the hinge 7 are respectively connected to the end of the first folding rod 2 away from the base 1 and the end of the second folding rod 3 away from the lighting device 4.

[0055] In this embodiment, the two ends of the hinge 7 are firmly connected to the first folding rod 2 and the second folding rod 3 through rivets, ensuring the tightness of the connection. The positioning groove 201 at the end of the first folding rod 2 away from the base 1 is a rectangular groove structure, and the opening edge is rounded to avoid scratching and jamming when the second folding rod 3 is rotated. When the first folding rod 2 and the second folding rod 3 are rotated to the axis coinciding, the side wall of the second folding rod 3 tightly abuts the side wall of the positioning groove 201. In daily use, the positioning groove 201 limits the relative position of the two, preventing the hinge 7 from bearing too much shearing force or torsional force.

[0056] The advantage is that the positioning groove 201 effectively shares the pressure of the hinge 7 when the first folding rod 2 and the second folding rod 3 are rotated to the axis coinciding, reducing the risk of damage to the hinge 7 and prolonging the life of the hinge 7 and the lighting device.

[0057] Further, the second folding rod 3 has a clamping groove 301 at the end close to the positioning groove 201, and a clamping piece 8 is slidingly arranged on the side wall of the positioning groove 201, one end of which is located in the positioning groove 201. One end of the clamping piece 8 located in the positioning groove 201 has an abutting surface 801 and a clamping surface 802. After the second folding rod 3 is unfolded, the side wall of one end of the second folding rod 3 abuts the abutting surface 801, and the clamping piece 8 is pushed to slide, so that the clamping surface 802 abuts the inner wall of the clamping groove 301, which is used to limit the relative position of the first folding rod 2 and the second folding rod 3.

[0058] In this embodiment, the clamping piece 8 slides on the side wall of the positioning groove 201. The abutting surface 801 of the clamping piece 8 located at one end in the positioning groove 201 is a slope. When the second folding rod 3 is unfolded, the side wall of the second folding rod 3 gradually contacts the abutting surface 801 and pushes the clamping piece 8 to slide along the guide rail, so that the clamping surface 802 of the clamping piece 8 abuts against the inner wall of the clamping groove 301.

[0059] The advantage is that the cooperation of the clamping piece 8 and the clamping groove 301 quickly locks the relative position of the first folding rod 2 and the second folding rod 3. In the unfolded state of the lighting device, the stability of the structure can be ensured, the lighting angle can be prevented from changing due to external interference, and the stability and reliability of the lighting effect can be ensured.

[0060] Further, the first elastic piece 9 is arranged, and the two ends of the first elastic piece 9 act on the clamping piece 8 and the side wall of the positioning groove 201 respectively, for providing a force for the clamping piece 8 to approach the first folding rod 2.

[0061] In this embodiment, one end of the first elastic piece 9 is fixed on the clamping piece 8, and the other end is hung on the side wall of the positioning groove 201. When the clamping piece 8 is pushed and slides by the second folding rod 3, the spring is compressed, and the elastic potential energy is stored. Once the external force disappears, the elastic restoring force of the spring pushes the clamping piece 8 back to the initial position, so that the clamping surface 802 and the clamping groove 301 are kept in close abutment.

[0062] The advantage is that the arrangement of the first elastic piece 9 enhances the stability and reliability of the clamping between the clamping piece 8 and the clamping groove 301. It can automatically compensate for the loosening of the clamping caused by various factors, always keep the close contact between the clamping surface 802 and the inner wall of the clamping groove 301, and further improve the structural stability of the lighting device in the unfolded state.

[0063] Further, the first sliding groove 302 and the second sliding groove 303 are arranged at the end of the second folding rod 3 away from the lighting device 4, the first sliding groove 302 and the second sliding groove 303 are communicated, the clamping piece 8 located at one end in the positioning groove 201 further has a pushing surface 803, and the pressure rod 10 is slidingly arranged in the first sliding groove 302, one end of the pressure rod 10 extends out of the first sliding groove 302, the other end of the pressure rod 10 has a pressing surface 1001, the pushing rod 11 is slidingly arranged in the second sliding groove 303, after the pressure rod 10 slides, the pressing surface 1001 slidingly abuts against one end of the pushing rod 11, the pushing rod 11 is pushed to slide, the other end of the pushing rod 11 abuts against the pushing surface 803, the clamping piece 8 is pushed away from the second folding rod 3, and the clamping surface 802 is disengaged from the abutment with the clamping groove 301.

[0064] In this embodiment, the pressing rod 10 extends out of the first sliding groove 302 at one end, and the extrusion surface 1001 at the other end is a bevel. The push rod 11 is slidingly arranged in the second sliding groove 303. When the user presses the pressing rod 10, the extrusion surface 1001 slidingly abuts one end of the push rod 11, pushing the push rod 11 to slide along the second sliding groove 303, and the other end of the push rod 11 abuts the push surface 803 (which is a plane) of the clamping piece 8, thereby pushing the clamping piece 8 away from the second folding rod 3, so that the clamping surface 802 is disengaged from the clamping groove 301, and the first folding rod 2 and the second folding rod 3 are unlocked to facilitate folding operation.

[0065] The advantage is that the linkage mechanism of the pressing rod 10, the push rod 11 and the clamping piece 8 realizes a convenient and fast folding rod unlocking mode. The user only needs to press the pressing rod 10 to complete the unlocking of the relative position between the first folding rod 2 and the second folding rod 3, and the folding and storage of the lighting device is convenient. This design avoids the use of complex tools or tedious operation steps, and improves the flexibility and portability of the lighting device during use.

[0066] Further, the second elastic member 12 is further included, and the two ends of the second elastic member 12 act on the second folding rod 3 and the push rod 11 respectively, for providing a force for the push rod 11 to move away from the push surface 803.

[0067] In this embodiment, when the push rod 11 is pushed and slides by the pressing rod 10, the second elastic member 12 is stretched to store elastic potential energy. When the external force disappears (i.e. the pressing rod 10 is released), the elastic restoring force of the rubber spring pulls the push rod 11 back to the initial position, preparing for the next unlocking operation.

[0068] The advantage is that the second elastic member 12 provides reliable power support for the reset of the push rod 11, ensuring the cyclic use performance of the unlocking mechanism. It can make the unlocking mechanism quickly recover to the initial state after each operation, so that the next unlocking operation can be smoothly carried out.

[0069] Further, the top rod 13 is further included, and the top rod 13 is slidingly arranged in the side wall of the positioning groove 201, and one end of the top rod 13 is located in the positioning groove 201 and abuts against the side wall of the second folding rod 3. After the push rod 13 slides, the clamping surface 802 and the clamping groove 301 are tightly abutted.

[0070] In this embodiment, the top rod 13 is threadedly arranged in a circular through hole in the side wall of the positioning groove 201, and one end of the top rod 13 is located in the positioning groove 201 and in contact with the side wall of the second folding rod 3. After the clamping piece 8 is clamped into the clamping groove 301, the top rod 13 is rotated to make the top rod 13 slide into the positioning groove 201 along the through hole, thereby exerting pressure on the side wall of the second folding rod 3, and the clamping surface 802 and the clamping groove 301 are tightly abutted.

[0071] The advantage is that the tightness between the clamping piece 8 and the clamping groove 301 can be further enhanced by the jacking rod 13, effectively preventing the clamping from loosening due to external force (such as strong vibration, strong wind, etc.), and ensuring that the lighting device can still maintain stable lighting angle and effect under harsh conditions.

[0072] Further, the mounting plate 14 is further provided, and the base 1 is rotatably arranged on the mounting plate 14.

[0073] In the embodiment, the base 1 is rotatably connected to the center position of the mounting plate 14 through a rotating shaft, and a plurality of positioning holes are arranged on the rotating shaft, so that the base 1 can be fixed by bolts after being rotated to a suitable position on the mounting plate 14.

[0074] The advantage is that the base 1 is mounted on the mounting plate 14, and the angle can be adjusted in the horizontal direction, thereby expanding the application range of the lighting device.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
