[0002] When night fishing, lighting equipment is an indispensable tool. Typically, a lighting fixture consists of two parts: a pole and a spotlight. To accommodate multi-angle lighting needs, the design often uses a spherical universal connector to connect the pole and the spotlight, allowing for flexible adjustment of the spotlight in various directions.

[0003] However, this design presents some problems when the weight of the illumination lamp increases. Specifically, attempting to adjust the illumination lamp in one direction often affects the positioning stability in other directions, leading to inconvenience during the adjustment process and reducing overall operational efficiency and user experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a rotary adjustment structure and lamp to solve the technical problem in the related technology that when adjusting the lamp, a change in one direction will unintentionally change the position setting in another direction.

[0008] A second connecting seat is rotatably mounted on the adjusting seat, its rotation axis extending along a second direction, the second direction being perpendicular to the first direction; and

[0009] The locking assembly includes a first locking member and a second locking member that are independently disposed from each other. The first locking member is movably disposed on the first connecting seat and is used to restrict or unrestrict the rotation of the adjusting seat. The second locking member is movably disposed on the second connecting seat and is used to restrict or unrestrict the rotation of the second connecting seat.

[0010] Furthermore, the adjusting seat extends along the first direction and the second direction to form a first rotating shaft and a second rotating shaft, respectively. The first rotating shaft and the second rotating shaft are respectively connected to the first connecting seat and the second connecting seat, and can rotate relative to the corresponding first connecting seat and the second connecting seat.

[0011] Furthermore, the first connecting seat is provided with a first through hole to avoid the first rotating shaft; and / or

[0012] The second connecting seat is provided with a second through hole to avoid the second rotating shaft.

[0013] Furthermore, the first locking element is a first locking screw threaded onto the first connecting seat, and the first locking screw extends into the first through hole for contacting or separating from the first rotating shaft.

[0014] Furthermore, the first rotating shaft is provided with an annular groove, and the first locking screw can extend into the annular groove.

[0015] Furthermore, the second connecting seat is provided with a deformation port, which is connected to the second through hole, so that the second connecting seat can undergo elastic or plastic deformation and hold the second rotating shaft.

[0016] Furthermore, the second locking element is a second locking screw that passes through the deformation port, used to adjust the size of the deformation port.

[0017] This utility model provides a lamp, including the aforementioned rotary adjustment structure.

[0018] Furthermore, the lamp also includes a lamp post, which is detachably mounted on the first connecting seat.

[0019] Furthermore, the lamp also includes a lamp body assembly, which includes a detachable adapter and a fixing seat, with the fixing seat located on the second connector.

[0020] Furthermore, the fixed base is provided with a sliding groove, and the adapter is slidably disposed in the sliding groove.

In the locked state, the third locking member abuts against the closed end of the limiting port and restricts the adapter to the fixed seat. In the unlocked state, the third locking member is located at the open end of the limiting port, so that the adapter is separated from the fixed seat.

[0023] Furthermore, the third locking component includes a spring, a pressing rod, and a limiting protrusion. The spring is located inside the fixed seat. One end of the pressing rod is connected to the spring, and the other end extends out of the fixed seat.

[0045] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0047] In the embodiments of this utility model, such as Figures 1-2 As shown, the rotation adjustment structure includes: a first connecting seat 1, an adjusting seat 2, a second connecting seat 3, and a locking assembly; the adjusting seat 2 is rotatably disposed on the first connecting seat 1, and its rotation axis extends along a first direction; the second connecting seat 3 is rotatably disposed on the adjusting seat 2, and its rotation axis extends along a second direction, which is perpendicular to the first direction; the locking assembly includes a first locking member and a second locking member that are independently disposed from each other, the first locking member being movably disposed on the first connecting seat 1 for restricting or unrestricting the rotation of the adjusting seat 2, and the second locking member being movably disposed on the second connecting seat 3 for restricting or unrestricting the rotation of the second connecting seat 3.

[0048] Specifically, in this embodiment of the invention, the first connecting seat 1, the adjusting seat 2, and the second connecting seat 3 are connected sequentially. Under the action of external force, the adjusting seat 2 can rotate relative to the first connecting seat 1, and the second connecting seat 3 can rotate relative to the adjusting seat 2; that is, the second connecting seat 3 can rotate synchronously with the adjusting seat 2, and the second connecting seat 3 can rotate independently. Furthermore, the aforementioned rotation axes are defined as a first direction and a second direction that are perpendicular to each other. Thus, independent adjustment in multiple directions can be achieved under the action of external force, avoiding mutual interference in traditional single-axial adjustment. During adjustment, the user does not need to repeatedly adjust to achieve the optimal adjustment angle, improving the convenience of operation. It also reduces mechanical wear caused by frequent adjustments, helping to extend the service life of structural components. In this embodiment, the first direction is defined as being arranged along the vertical direction, and the second direction is defined as being arranged along the front-back direction. Therefore, this structure can be independently adjusted in the horizontal and vertical directions to change its horizontal and / or vertical angles.

[0049] In this embodiment of the invention, a first locking member and a second locking member are respectively provided on the first connecting seat 1 and the second connecting seat 3. The two locking members can move relative to the two connecting seats, thereby locking or releasing the corresponding rotation stroke. Since the first locking member and the second locking member correspond to different adjustment axes, the user can lock immediately after adjusting in a certain direction, thereby achieving precise fixing of the adjustment angle position. Furthermore, the independently provided locking members can lock the adjustment results in different directions respectively, eliminating the need for repeated adjustment and locking, thus simplifying the operation process. At the same time, in the locked state, it can remain in the predetermined position and will not easily move even under slight external force, which is very useful for lamps that need to maintain a specific angle for a long time. In addition, the independent locking mechanism reduces unnecessary linkage, reduces friction and wear between components, thereby extending the service life of the lamp.

[0050] This utility model embodiment, by designing a method that allows the lamp to rotate independently with a first or second direction as the axis, enables the lamp to perform well in various usage environments, whether it is night fishing or other occasions that require precise light source positioning; the stable locking mechanism ensures the stability of the light source; and it can selectively lock a certain direction according to actual needs without worrying about affecting the adjustment of other directions, thereby providing its flexibility and stability in use, and increasing the convenience and safety of use.

[0051] In one embodiment, such as Figure 2As shown, the adjusting seat 2 extends along a first direction and a second direction to form a first rotating shaft 21 and a second rotating shaft 23, respectively. The first rotating shaft 21 and the second rotating shaft 23 are respectively connected to the first connecting seat 1 and the second connecting seat 3, and can rotate relative to the corresponding first connecting seat 1 and the second connecting seat 3. Specifically, in order to make the rotation axis of the adjusting seat 2 set along the first direction and be able to rotate relative to the first connecting seat 1, and the rotation axis of the second connecting seat 3 set along the second direction and be able to rotate relative to the adjusting seat 2, this embodiment integrally forms two rotating shafts at both ends of the adjusting seat 2, defining the two rotating shafts as the first rotating shaft 21 and the second rotating shaft 23, and setting the axis of the first rotating shaft 21 along the first direction and the axis of the second rotating shaft 23 along the second direction; in this way, the adjusting seat 2 is connected to the first connecting seat 1 by the first rotating shaft 21, so that the adjusting seat 2 can rotate relative to the first connecting seat 1 and the second connecting seat 3 can rotate relative to the adjusting seat 2; thereby increasing the flexibility and stability of the structure and making it easy to install.

[0052] Furthermore, in one embodiment, as Figure 2 As shown, the first connecting seat 1 is provided with a first through hole 11 to avoid the first rotating shaft 21. Specifically, in order to install the first rotating shaft 21 at the first connecting seat 1, this embodiment provides a first through hole 11 at the first connecting seat 1 so that the first rotating shaft 21 can rotate within the first through hole 11. In addition, the second connecting seat 3 in this embodiment is provided with a second through hole 31 for installing the second rotating shaft 23, so that the second connecting seat 3 can rotate around the axis of the second rotating shaft 23.

[0053] In one embodiment, such as Figure 1 , Figure 2As shown, the first locking element is a first locking screw 4 threaded onto the first connecting seat 1. The first locking screw 4 extends into the first through hole 11 and is used to abut or separate from the first rotating shaft 21. Specifically, in order to precisely control the rotation angle of the adjusting seat 2 and facilitate operation, this embodiment sets the first locking element as a first locking screw 4, so that the first locking screw 4 can be threaded through the first connecting seat 1 and extend into the first through hole 11 therein, thereby abutting or separating from the first rotating shaft 21; when the two are abutting, it is used to restrict the rotation of the adjusting seat 2; conversely, when the two are separated, the adjusting seat 2 can rotate freely under the action of external force. At the same time, threaded connections are generally more robust and can withstand greater torque without being easily damaged; in addition, a knurled nut is fitted on the end of the first locking screw 4, which makes it easy to tighten or loosen the screw manually without the need for complicated tools or equipment. Of course, in other embodiments, since there is a gap between the first rotating shaft 21 and the first through hole 11, and in order to further limit the rotation angle of the adjusting seat 2, damping oil is injected into the gap. The damping oil can achieve the purpose of temporary positioning by generating a certain resistance between the components.

[0054] Preferably, such as Figure 2 As shown, the first rotating shaft 21 is provided with an annular groove 22, into which the first locking screw 4 can extend. The annular groove 22 corresponds to the first locking screw 4, providing a stable contact surface so that the first locking screw 4 can effectively contact the first rotating shaft 21 and apply locking force after being inserted, ensuring the stability of the connection and achieving precise positioning, avoiding loosening or misalignment caused by inaccurate positioning. Furthermore, the presence of the annular groove 22 allows the user to control the position of the first rotating shaft 21 by adjusting the depth of the locking screw, facilitating fine-tuning and rapid positioning. Moreover, when the first locking screw 4 is inserted into the annular groove 22, it prevents the first rotating shaft 21 from slipping or shifting under stress, enhancing the overall structural reliability.

[0055] In one embodiment, such as Figure 2As shown, the second connecting seat 3 is provided with a deformation port 32, which communicates with the second through hole 31, allowing the second connecting seat 3 to undergo elastic or plastic deformation and hold the second rotating shaft 23. Specifically, in order to fix the second connecting seat 3 at any angle, this embodiment adds a deformation port 32 to the second connecting seat 3. This deformation port 32 communicates with the second through hole 31, allowing the second connecting seat 3 to have a certain deformation capacity, thereby generating a certain clamping force on the second rotating shaft 23 and ensuring the stability of the second rotating shaft 23. At the same time, the design of the deformation port 32 can reduce the loosening of the rotating shaft caused by vibration or external forces, improving the reliability of equipment operation. It should be noted that the effectiveness of the deformation port 32 depends on the choice of material and the specific design of the deformation port 32 (such as shape, size, etc.). In practical applications, the design needs to be optimized according to the specific working conditions and expected load.

[0056] Preferably, the second locking element is a second locking screw 5 that passes through the deformation port 32, used to adjust the size of the deformation port 32. The second through hole 31, the deformation port 32, and the second locking screw 5 of the second connecting seat 3 together form a clamp-like structure, allowing the second locking screw 5 to precisely adjust the size of the deformation port 32, thereby controlling the holding force of the second connecting seat 3 on the second rotating shaft 23 and ensuring a stable and reliable connection. During operation, the pressure of the deformation port 32 on the second rotating shaft 23 can be increased or decreased by adjusting the second locking screw 5, thereby enhancing or weakening its tightness to adapt to different angle adjustment requirements. At the same time, the adjusted second locking screw 5 can effectively prevent the second rotating shaft 23 from loosening due to vibration or other reasons during use; if it is necessary to readjust or disassemble the second rotating shaft 23, it can be easily achieved by simply rotating the locking screw in the opposite direction, increasing the convenience of maintenance and adjustment. Of course, if Figure 1 , Figure 2 As shown, in this embodiment, the end of the second locking screw 5 is provided with a small flathead wrench, making manual operation simpler and faster.

[0057] like Figure 3 As shown, this embodiment also provides a lamp, including the above-described rotary adjustment structure. The specific structure of the rotary adjustment structure is the same as that in the above embodiment. Since this lamp adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0058] In one embodiment, such as Figure 3As shown, the lamp fixture also includes a lamp post 6, which is detachably mounted on the first connecting seat 1. The lamp post 6 and the first connecting seat 1 are connected by a thread, allowing for flexible adjustment according to different usage scenarios and needs. The lamp post 6 can be detached, facilitating the packaging and transportation of the lamp fixture, reducing space occupation, and lowering transportation costs.

[0059] In one embodiment, such as Figure 3 , Figure 4 As shown, the lamp also includes a lamp body assembly 7, which includes a detachable adapter 71 and a fixing base 73. The fixing base 73 is located on the second connecting base 3. Specifically, to adapt to different scenario requirements and facilitate maintenance and replacement, this embodiment uses a fixing base 73 (fixed together with screws) on the second connecting base 3 as an intermediate connector, allowing the adapter 71 to be detachably installed on the fixing base 73. This makes it easy to remove the adapter 71 from the fixing base 73, facilitating the replacement of damaged light sources or cleaning and maintenance. Even after removal, the adapter 71 is easy to hold and charge, making it more flexible to use. Furthermore, when a component is damaged, only that component needs to be replaced, rather than the entire lamp, significantly reducing costs. Of course, in other embodiments, the detachable design can also add additional functional modules, such as intelligent control modules and sensors, to enhance the lamp's functionality. In addition, the adapter 71 can be used as an independent light-emitting component, such as an independently set LED light board; or as a transfer component, such as installing the light-emitting component at the adapter 71 and using the adapter 71 to connect the light-emitting component to the fixed base 73.

[0060] Furthermore, in one embodiment, as Figure 4 As shown, the fixed base 73 is provided with a sliding groove 74, and the adapter 71 is slidably disposed in the sliding groove 74. Specifically, in order to achieve a detachable connection between the adapter 71 and the fixed base 73, this embodiment provides a sliding groove 74 at the fixed base 73, and the outward protrusion of the adapter 71 can slide in the sliding groove 74, so that the adapter 71 can slide under the action of external force, so as to quickly install or remove the adapter 71.

[0061] Preferably, such as Figure 4As shown, the width of the slide 74 gradually decreases along its length. The gradually narrowing slide 74 provides excellent guidance, making it easier for the adapter 71 to move along a predetermined path and reducing the risk of deviation. That is, when the adapter 71 moves along the gradually narrowing slide 74, even with a slight initial position deviation, it can automatically adjust to the correct position through sliding, reducing human error during installation or adjustment. Simultaneously, the gradually narrowing slide 74 allows the adapter 71 to be naturally clamped after moving to the designated position due to the reduced width, thereby improving tightness and stability.

[0062] In one embodiment, such as Figures 4-7 As shown, the adapter 71 has a limiting opening 72 that is closed at one end and open at the other. The fixed base 73 is movably provided with a third locking member 8, which has a locked state and an unlocked state. In the locked state, the third locking member 8 abuts against the closed end of the limiting opening 72 and restricts the adapter 71 to the fixed base 73. In the unlocked state, the third locking member 8 is located at the open end of the limiting opening 72, so that the adapter 71 can be separated from the fixed base 73. Specifically, in order to prevent the adapter 71 from falling freely along the sliding groove 74 of the fixed base 73, this embodiment provides a matching limiting opening 72 and a third locking member 8 on the opposite end faces of the adapter 71 and the fixed base 73, respectively. The cooperation of the two is used to restrict or release the adapter 71, so as to achieve the purpose of quick positioning, installation and disassembly of the adapter 71.

[0063] Specifically, such as Figure 7 As shown, a limiting port 72 is provided at the bottom of the adapter 71. The cross-section of the limiting port 72 is generally L-shaped, with one end closed and the other end extending to the end of the adapter 71 and in an open state (e.g., Figure 7 As shown, an inclined surface is provided inside the limiting port 72, with its two ends extending towards the closed end and the open end of the limiting port 72, respectively, so that the closed end of the limiting port 72 forms a constricted structure (which can limit the third locking member in the locked state); in addition, the third locking member 8 is movably provided in the fixing base 73, so that the third locking member 8 has two states: locked and unlocked; in the locked state, the third locking member 8 abuts against the closed end of the limiting port 72, which can effectively fix the adapter 71 and prevent it from loosening or falling off due to vibration or other external forces; that is, the third locking member 8 in the locked state can ensure that the adapter 71 will not accidentally fall off the fixing base 73 during use, thus improving the safety of the lamp. Conversely, in the unlocked state, the third locking member 8 is located at the open end of the limiting port 72, which makes it easy to remove the adapter 71 from the fixed seat 73 and install it very conveniently; when the adapter 71 needs to be replaced, only the adapter 71 itself needs to be replaced, without replacing the entire lamp, thus reducing maintenance costs.

[0064] Furthermore, in one embodiment, as Figure 5 , Figure 6 , Figure 8 As shown, the third locking member 8 includes a spring 81, a pressing rod 82, and a limiting protrusion 83. The spring 81 is disposed within the fixed base 73. One end of the pressing rod 82 is connected to the spring 81, and the other end extends out of the fixed base 73. The pressing rod 82 located within the fixed base 73 has a limiting protrusion 83 for extending into the limiting port 72. Specifically, to enable the third locking member 8 to be movably disposed within the fixed base 73, this embodiment defines the third locking member 8 as a spring 81 and a pressing rod 82 connected in sequence, and a limiting protrusion 83 disposed on the pressing rod 82. During installation, one end of the spring 81 is fixed within the fixed base 73, and the other end is connected to the pressing rod 82, while ensuring that the end of the pressing rod 82 protrudes from the fixed base 73 as the pressing position. During operation, pressing the pressing rod 82 compresses the spring 81 and simultaneously activates the limiting protrusion 83. The protrusion 83 moves within the lower limit opening 72, moving from the closed end to the open end of the limit opening 72, at which point the light-emitting component can be disassembled. Conversely, after the adapter 71 is in place, releasing the pressing rod 82 during the pressing process causes the compressed spring 81 to reset and push the pressing rod 82, causing the limiting protrusion 83 to move from the open end to the closed end of the limit opening 72. Since the closed end is in a closed state in the sliding direction of the adapter 71, the movement of the adapter 71 is restricted, thus fixing it at the fixed seat 73. In this way, the user only needs to press the pressing rod 82 to unlock the adapter 71, making the operation simple and quick. In the locked state, the limiting protrusion 83 is deeply inserted into the limit opening 72, which can effectively prevent the adapter 71 from loosening or falling off during use. At the same time, the spring 81 allows the pressing rod 82 to automatically reset without external force, reducing the need for manual reset.

[0065] In one embodiment, such as Figure 4 , Figure 6 As shown, the fixing base 73 has an opening 75, the length direction of which is along the deformation direction of the spring 81, and the limiting protrusion 83 passes through the opening 75. Specifically, in order to enable the limiting protrusion 83 to move synchronously with the pressing rod 82, this embodiment provides an opening 75 on the surface of the fixing base 73, the length direction of which is consistent with the pressing direction of the pressing rod 82, so as to provide sufficient movement space for the limiting protrusion 83, allowing the limiting protrusion 83 to slide between the closed end and the open end of the limiting opening 72 under the drive of the pressing rod 82, avoiding the restriction of the fixing base 73 on it.

[0066] like Figure 8As shown, the limiting protrusion 83 is threadedly connected to the pressing rod 82; this facilitates the installation of the limiting protrusion 83 on the circumferential surface of the pressing rod 82, increases the contact area between the two, and prevents the limiting protrusion 83 from falling off.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
