Description

Technical Field

[0001] This invention relates to the field of lighting electrical appliances technology, and more specifically, to a lamp fixing mechanism. Background Technology

[0002] Many lighting fixtures on the market currently use magnetic installation, fixing them to the mounting structure via magnetic attraction, such as track lights magnetically attached to the track. This makes installation and removal relatively simple and convenient. However, after a period of use, the magnetic force may degrade, creating a risk of the fixture detaching from the mounting structure. This is especially true for pendant lights and track lights installed at high locations; if they detach, they could fall, posing a significant safety hazard. Furthermore, the magnetic force of the internal magnetic components can interfere with the electrical components of the fixture, affecting its power supply and signal transmission performance.

[0003] Many lighting fixtures on the market currently employ fixed installation methods, such as having elastic mounting elements on the lamp housing or directly designing the lamp housing as an elastic mounting element. These elements are then fixed to the mounting structure by pushing, pulling, or pressing. For example, a portion of the lamp housing is designed as a spring-loaded lever, which is then fixed to the mounting structure by pushing, pulling, or pressing. However, these elastic mounting elements are prone to deformation after a period of use, affecting the secure installation.

[0004] JP2005329133A discloses a connector applicable to the connecting parts of various items, enabling simple and quick assembly and disassembly with a single press. This connector includes a connecting recess and a connecting protrusion, achieving simple connection and disassembly through alternating movement of two positions: engagement and release. For example, referring to Figure 47, it is applied to the connection of a light bulb. However, as can be seen from the entire text, it can only be used for connections between the connecting recess and the connecting protrusion. If applied to the mounting and fixing of light fixtures, the light fixture housing and mounting structure need to be respectively designed as corresponding connecting recesses and protrusions. This restricts the external shape of the light fixture and mounting structure to have connecting recesses and protrusions, which is detrimental to aesthetic design and greatly reduces the range of applications. For example, it can only be used for connecting simple light bulbs or chandeliers, and cannot be used for the mounting and fixing of most other light fixtures. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems to at least some extent.

[0006] The purpose of this invention is to provide a lighting fixture fixing mechanism that can stably fix lighting fixtures for a long time, is easy to assemble and disassemble, and has wider applicability.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: a lamp fixing mechanism, including a fixing base, an adjusting member, a fixing part, a pressing part, and a lamp housing. The fixing base is fixedly connected to the fixing part and fixed inside the lamp housing. The fixing base is provided with a first elastic member. The fixing part is provided with a through hole. One end of the adjusting member abuts against the first elastic member, and the other end of the adjusting member is disposed in the through hole. The end of the adjusting member abutting against the first elastic member is provided with a first release surface, a transition surface, and a first abutting surface distributed circumferentially along the radial direction of the through hole. The first release surface and the first abutting surface form the transition surface. The radial dimension of the first release surface is smaller than the radial dimension of the first abutting surface, resulting in a radial width difference between the first release surface and the first abutting surface. The other end of the adjusting member disposed in the through hole is provided with multiple sets of second abutting surfaces and second abutting surfaces distributed circumferentially along the axial direction of the through hole. The second abutment surface has an axial dimension greater than that of the second release surface, creating an axial height difference between the two surfaces. The inner wall of the through hole is provided with multiple sets of third abutment surfaces, guide surfaces, and release grooves distributed circumferentially along the axial direction of the through hole. The axial dimension of the third abutment surface is smaller than that of the guide surface, creating an axial height difference between the two surfaces. The second abutment surface, the second release surface, the third abutment surface, and the guide surface are respectively set as inclined surfaces. One end of the pressing part is located in the through hole and is provided with multiple sets of first abutment protrusions. The lamp housing is provided with at least one fixing groove. The fixing part is provided with a fixing member corresponding to the position of the fixing groove. The fixing member is provided with a fixing block and a second elastic member on the side facing the fixing groove. The fixing block matches the shape of the fixing groove. The fixing member is provided with a second abutment protrusion on the side facing the adjusting member.

[0008] When used to install and fix a lamp, this invention assumes that the fixing base, adjusting member, fixing part, and pressing part are arranged sequentially from top to bottom. An upward pressing force is applied to the pressing part, causing the first abutting protrusion of the pressing part to abut against the second abutting surface of the adjusting member, pushing the adjusting member upward along the axial direction of the through hole. The second abutting protrusion gradually transitions from abutting against the first release surface to abutting against the first abutting surface, thereby pushing the fixing member towards the lamp housing. Finally, the fixing block passes through the fixing groove and extends out of the lamp housing. The fixing block can be used to fix the lamp to the mounting structure. Because the second abutting surface, second release surface, third abutting surface, and guide surface are correspondingly set as inclined surfaces, the adjusting member also rotates during axial movement. The second abutting surface of the adjusting member rises from the release groove in the through hole and gradually transitions to abutting against the third abutting surface in the through hole. After the pressing part is released after fixing, the adjusting part is subjected to the reaction force of the first elastic element, and the second abutting surface of the adjusting part falls on the third abutting surface in the through hole. It is stopped by the third abutting surface and the step between the third abutting surface and the guide surface.

[0009] When used to disassemble a lamp, this invention applies an upward pressing force to the pressing part again. The first abutting protrusion of the pressing part abuts against the second abutting surface of the adjusting member, pushing the adjusting member upward along the axial direction of the through hole. Since the second abutting surface, the second release surface, the third abutting surface, and the guide surface are correspondingly set as inclined surfaces, the adjusting member will also rotate during axial movement. After rising from the third abutting surface in the through hole, the second abutting surface of the adjusting member gradually transitions to abutting against the guide surface in the through hole, and after abutting against the guide surface in the through hole, it is guided into the release groove in the through hole. After releasing the pressing part, since there is no abutting between the second abutting surface and the release groove, the adjusting member is subjected to the reaction force of the first elastic member and moves downward along the axial direction of the through hole. The second release surface of the adjusting member falls on the third abutting surface in the through hole, abutted by the third abutting surface and stopped by the step between the third abutting surface and the guide surface. At the same time, the second abutting protrusion gradually transitions from abutting the first abutting surface to abutting the first release surface. The fixing member is subjected to the reaction force of the second elastic member and moves away from the lamp housing. Finally, the fixing block passes through the fixing groove and retracts into the lamp housing, so that the lamp can be removed from the mounting structure.

[0010] This invention allows the fixing block to extend out of and retract into the lamp housing sequentially by pressing the pressing part. The fixing mechanism mechanically locks or unlocks, repeating this cycle repeatedly, making assembly and disassembly simple and convenient, thus replacing magnetic installation. It eliminates the need for magnetic components, avoiding interference with the electrical components inside the lamp and ensuring the lamp's power supply and signal transmission performance. Once installed and fixed, the lamp remains stable for a long time, and the lamp housing will not deform elastically.

[0011] Furthermore, this invention houses almost all the main components of the fixing mechanism, except for the lamp housing, within the lamp housing, requiring only simple fixing grooves on the lamp housing. Simultaneously, the lamp's mounting structure only needs simple fixing positions to secure the fixing block. Therefore, there's no need to design corresponding connecting recesses and protrusions for the lamp housing and mounting structure, thus not restricting the external shape of the lamp and mounting structure, allowing for various aesthetically pleasing designs. The application range is also greatly expanded, making it suitable for the installation and fixing of lamps of various types and scenarios.

[0012] In one embodiment, the adjusting member has a directional post at one end within the through hole, the directional post extending axially relative to the second abutment surface and the second release surface. The pressing part has a directional hole at one end within the through hole, the inner wall of the directional hole forming the first abutment protrusion between the inner wall of the directional hole and the outer wall of the pressing part. The directional post is inserted into the directional hole. The adjusting member is subjected to forces from the first elastic member and the pressing part in the axial direction of the through hole, and to a force from the fixing member in the radial direction of the through hole, making it prone to swaying during movement. Inserting the directional post, which extends axially relative to the second abutment surface and the second release surface, into the directional hole prevents the adjusting member from swaying during axial movement and rotation, ensuring smooth movement. After the directional post is inserted into the directional hole, the first abutment protrusion is aligned with the second abutment surface in the axial direction, applying pressure to the pressing part, thus forming an abutment between the first abutment protrusion of the pressing part and the second abutment surface of the adjusting member.

[0013] In one embodiment, the outer wall of one end of the pressing part located within the through hole is provided with first directional blocks distributed circumferentially, and the inner wall of the through hole is provided with first directional grooves distributed circumferentially. The number of first directional blocks is equal to the number of first directional grooves, and the first directional blocks are respectively engaged in the first directional grooves. The dimensions of the first directional blocks and the first directional grooves correspond in the radial and circumferential directions, so that the first directional blocks can be engaged in the first directional grooves to provide orientation for the movement of the pressing part. This orientation function is effective throughout the entire circumferential direction, preventing the pressing part from swaying or rotating axially and ensuring smooth movement. Preferably, the end of the first directional block facing the first directional groove is provided as an arc surface to facilitate engagement in the first directional groove.

[0014] In another embodiment, the outer wall of one end of the pressing part located within the through hole is provided with first directional blocks distributed circumferentially, and the inner wall of the through hole is provided with first directional grooves distributed circumferentially. The number of first directional blocks is equal to the sum of the number of first directional grooves and release grooves. The first directional blocks are respectively engaged in the first directional grooves and release grooves. The dimensions of the first directional blocks correspond to the radial and circumferential dimensions of the first directional grooves and release grooves, respectively, so that the first directional blocks can be engaged in the first directional grooves and release grooves to provide orientation for the movement of the pressing part. This orientation function is effective throughout the entire circumferential direction, preventing the pressing part from swaying or rotating axially, ensuring smooth movement. A larger number of first directional blocks provides better orientation.

[0015] In one embodiment, the fixing member is provided with at least one second directional block, and the fixing part is provided with at least one second directional groove. The second directional block is engaged in the second directional groove, and the radial width difference between the second directional groove and the second directional block is greater than or equal to the radial width difference between the first release surface and the first abutment surface. The two sides of the fixing member are subjected to the forces of the adjusting member and the second elastic member respectively in the radial direction of the through hole, making it prone to non-directional movement during operation. Engaging the second directional block in the second directional groove ensures that the fixing member moves in a directional and stable manner, and that the fixing block is always aligned with the direction of the fixing groove. Furthermore, the radial width difference between the second directional groove and the second directional block is greater than or equal to the radial width difference between the first release surface and the first abutment surface, meaning that the second directional groove not only provides orientation for the fixing member but also continuously provides a fixing function. That is, during the movement of the fixing member, the second directional block is always engaged in the second directional groove, making it difficult to disengage and ensuring long-term stable and reliable use.

[0016] In a preferred embodiment, the pressing part is provided with a pressing member, the pressing member is provided with a mounting post, the mounting post is provided with a first mounting hole, and the pressing part is provided with a second mounting hole. The first mounting hole and the second mounting hole are connected by a first fastener. The axes of the mounting post, the first mounting hole, and the second mounting hole are collinear and parallel to the axis of the through hole. Since the telescopic mechanism has many components, and there are other lamp components inside the lamp housing, such as reflectors, heat sinks, and drive components, and the space for installing these components inside the lamp housing is limited, it is impossible to install all the components of the telescopic mechanism in the same axial direction. Therefore, some components need to be disassembled or staggered. Disassembling the pressing member from the pressing part facilitates the spatial arrangement of components inside the lamp housing. Furthermore, since the axes of the mounting post, the first mounting hole, and the second mounting hole are collinear and parallel to the axis of the through hole, applying axial force to the pressing member will be transformed into applying axial force to the pressing part.

[0017] In a preferred embodiment, the transition surface is a conical surface. Since the adjusting member both moves axially and rotates, setting the transition surface as a conical surface allows the second abutting protrusion to abut more smoothly when moving between the first release surface and the first abutting surface, preventing the fixing member from getting stuck or jumping during movement.

[0018] In a preferred embodiment, the fixing base is provided with a first fixing post, and the end of the adjusting member that abuts against the first elastic member is provided with a fixing hole. One end of the first elastic member is sleeved on the first fixing post, and the other end of the first elastic member is disposed in the fixing hole. The axes of the first fixing post, the fixing hole, and the first elastic member are collinear. The first fixing post and the fixing hole can effectively fix the first elastic member, preventing the first elastic member from shifting its position under pressure. Furthermore, because the axes of the first fixing post, the fixing hole, and the first elastic member are collinear, it is ensured that the first elastic member can always elastically expand and contract in the direction of the common axis of the three.

[0019] In a preferred embodiment, a second fixing post is provided on the side of the fixing member facing the fixing groove. One end of the second elastic member is sleeved on the second fixing post, and the axis of the second fixing post is collinear with the axis of the second elastic member. The second fixing post can effectively fix the second elastic member, preventing the second elastic member from shifting its position under pressure. Furthermore, since the axis of the second fixing post is collinear with the axis of the second elastic member, it ensures that the second elastic member can always elastically expand and contract in the direction of their common axis.

[0020] In a preferred embodiment, the fixing base is provided with a third mounting hole, the fixing part is provided with a fourth mounting hole, and the third mounting hole and the fourth mounting hole are connected by a second fastener.

[0021] The beneficial effects of this invention are as follows: By pressing the pressing part, the fixing block can be sequentially extended outside and retracted inside the lamp housing. The fixing mechanism mechanically locks or unlocks, repeating this cycle repeatedly, making assembly and disassembly simple and convenient, thus replacing the magnetic installation method. It eliminates magnetic components, avoiding interference with the electrical components inside the lamp, and ensuring the lamp's power supply and signal transmission performance. The lamp is stable after installation and fixation, and the lamp housing will not deform elastically. Furthermore, this invention places most of the main components of the fixing mechanism, except for the lamp housing, inside the lamp housing, requiring only simple fixing grooves on the lamp housing. Simultaneously, the lamp's mounting structure only needs simple fixing positions to hold the fixing block. Therefore, there is no need to design corresponding connecting recesses and protrusions for the lamp housing and mounting structure, thus not restricting the external shape of the lamp and mounting structure, allowing for various aesthetically pleasing designs. The application range is also greatly expanded, making it suitable for the installation and fixation of lamps of various types and scenarios. Attached Figure Description

[0035] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figures 1 to 13As shown, a lamp fixing mechanism of the present invention includes a fixing base 100, an adjusting member 200, a fixing part 300, a pressing part 400, and a lamp housing 500. The fixing base 100 is fixedly connected to the fixing part 300 and fixed inside the lamp housing 500. In this embodiment, the fixing base 100 is provided with a third mounting hole 101, and the fixing part 300 is provided with a fourth mounting hole 301. The third mounting hole 101 and the fourth mounting hole 301 are connected by a second fastener 600. In this embodiment, the second fastener 600 is a screw.

[0039] The fixed base 100 is provided with a first elastic element 102, and one end of the adjusting member 200 abuts against the first elastic element 102. The fixed base 100 is provided with a first fixing post 103, and the end of the adjusting member 200 that abuts against the first elastic element 102 is provided with a fixing hole 201. One end of the first elastic element 102 is sleeved on the first fixing post 103, and the other end of the first elastic element 102 is disposed in the fixing hole 201. The axes of the first fixing post 103, the fixing hole 201, and the first elastic element 102 are collinear. The first fixing post 103 and the fixing hole 201 can effectively fix the first elastic element 102, preventing the first elastic element 102 from moving under pressure. Furthermore, since the axes of the first fixing post 103, the fixing hole 201, and the first elastic element 102 are collinear, it is ensured that the first elastic element 102 can always elastically expand and contract in the direction of the common axis of the three.

[0040] The fixing part 300 is provided with a through hole 302, and the other end of the adjusting member 200 is disposed within the through hole 302. The end of the adjusting member 200 that abuts against the first elastic member 102 is provided with a first release surface 202 and a first abutment surface 203 arranged circumferentially along the radial direction of the through hole. The radial dimension of the first release surface 202 is smaller than the radial dimension of the first abutment surface 203, resulting in a radial width difference between the first release surface 202 and the first abutment surface 203. A transition surface 204 is formed between the first release surface 202 and the first abutment surface 203. In this embodiment, the transition surface 204 is a smooth conical surface. The other end of the adjusting member 200 disposed within the through hole 302 is provided with multiple sets of second abutment surfaces 205 and second release surfaces 206 arranged circumferentially along the axial direction of the through hole. The axial dimension of the second abutment surface 205 is larger than the axial dimension of the second release surface 206, resulting in an axial height difference between the second abutment surface 205 and the second release surface 206.

[0041] The inner wall of the through hole 302 is provided with multiple sets of third abutment surfaces 303, guide surfaces 304, and release grooves 305 distributed circumferentially along the axial direction of the through hole. The axial dimension of the third abutment surface 303 is smaller than the axial dimension of the guide surface 304, so that an axial height difference is formed between the third abutment surface 303 and the guide surface 304. The second abutment surface 205, the second release surface 206, the third abutment surface 303, and the guide surface 304 are respectively set as inclined surfaces.

[0042] The lamp housing 500 is provided with at least one fixing groove 501. The fixing part 300 is provided with a fixing member 306 corresponding to the fixing groove 501. The fixing member 306 is provided with a fixing block 307 and a second elastic member 308 on the side facing the fixing groove 501. The fixing block 307 matches the shape of the fixing groove 501. The fixing member 306 is provided with a second abutting protrusion 309 on the side facing the adjusting member 200. In this embodiment, each of the lamp housings 500 on both sides is provided with a fixing groove 501. The fixing grooves 501 on both sides are radially symmetrical with respect to the through hole 302. Therefore, the fixing member 306 is also provided in two parts and is radially symmetrical with respect to the through hole 302.

[0043] The fixing member 306 is provided with at least one second directional block 310, and the fixing part 300 is provided with at least one second directional groove 311, into which the second directional block 310 engages. In this embodiment, two second directional blocks 310 and two second directional grooves 311 are provided on each side. The radial width difference between the second directional groove 311 and the second directional block 310 is greater than or equal to the radial width difference between the first release surface 202 and the first abutment surface 203.

[0044] The fixing member 306 has a second fixing post 312 on the side facing the fixing groove 501. One end of the second elastic member 308 is fitted onto the second fixing post 312, and the other end abuts against the inner wall of the lamp housing 500. The axis of the second fixing post 312 is collinear with the axis of the second elastic member 308. The second fixing post 312 effectively fixes the second elastic member 308, preventing the second elastic member 308 from shifting under pressure. Furthermore, because the axis of the second fixing post 312 is collinear with the axis of the second elastic member 308, it ensures that the second elastic member 308 can always elastically expand and contract in the direction of their common axis.

[0045] One end of the pressing part 400 is disposed in the through hole 302 and is provided with multiple sets of first abutting protrusions 401. One end of the adjusting member 200 disposed in the through hole 302 is provided with a directional post 207, the directional post 207 extending axially relative to the second abutting surface 205 and the second release surface 206. One end of the pressing part 400 disposed in the through hole 302 is provided with a directional hole 402, the inner wall of the directional hole 402 and the outer wall of the pressing part 400 form the first abutting protrusion 401, and the directional post 207 is inserted into the directional hole 402.

[0046] In this embodiment, the outer wall of one end of the pressing part 400 located within the through hole 302 is provided with a first directional block 403 distributed circumferentially, and the inner wall of the through hole 302 is provided with a first directional groove 313 distributed circumferentially. The number of the first directional blocks 403 is equal to the sum of the number of the first directional grooves 313 and the release grooves 305. The first directional blocks 403 are respectively engaged in the first directional grooves 313 and the release grooves 305. In this embodiment, the end of the first directional block 403 facing the first directional groove 313 is set as an arc surface to facilitate engagement in the first directional grooves 313 and the release grooves 305. The dimensions of the first directional blocks 403 correspond to those of the first directional grooves 313 and the release grooves 305 in the radial and circumferential directions, respectively, so that the first directional blocks 403 can be engaged in the first directional grooves 313 and the release grooves 305 to provide orientation for the movement of the pressing part 400. Furthermore, the orientation function can be provided throughout the entire circumferential direction, preventing the pressing part 400 from swinging or rotating left and right during axial movement and ensuring smooth movement. A larger number of first orientation blocks 403 can better perform the orientation function.

[0047] In this embodiment, the pressing part 400 is provided with a pressing member 404, the pressing member 404 is provided with a mounting post 405, the mounting post 405 is provided with a first mounting hole 406, and the pressing part 400 is provided with a second mounting hole 407. The first mounting hole 406 and the second mounting hole 407 are connected by a first fastener 408. In this embodiment, the first fastener 408 is a screw. The axes of the mounting post 405, the first mounting hole 406, and the second mounting hole 407 are collinear and parallel to the axis of the through hole 302. Because the telescopic mechanism has many components, and there are other lamp components inside the lamp housing, such as reflectors, heat sinks, and drive components, and the space for installing components inside the lamp housing is limited, it is impossible to install all the components of the telescopic mechanism in the same axial direction. Therefore, some components need to be disassembled or staggered. Separating the pressing member 404 from the pressing part 400 facilitates the spatial arrangement of components inside the lamp housing. Furthermore, since the axes of the mounting post 405, the first mounting hole 406, and the second mounting hole 407 are collinear and parallel to the axis of the through hole 302, applying an axial force to the pressing member 404 will be transformed into applying an axial force to the pressing part 400.

[0048] When this invention is used for installing and fixing light fixtures, such as Figure 1 As shown, the fixed base 100, adjusting member 200, fixing part 300, and pressing part 400 are arranged sequentially from top to bottom. Applying an upward pressing force to the pressing member 404 transforms into applying an upward pressing force to the pressing part 400. The first abutting protrusion 401 of the pressing part 400 abuts against the second abutting surface 205 of the adjusting member 200, pushing the adjusting member 200 to move upward along the axial direction of the through hole. The first directional block 403 is respectively inserted into the first directional groove 313 and the release groove 305 to guide the movement of the pressing part, thereby preventing the pressing part from swinging left and right or rotating during axial movement.

[0049] The adjusting member 200 moves upward along the axial direction of the through hole. The second abutting protrusion 309 gradually transitions from abutting against the first release surface 202 to abutting against the first abutting surface 203 after passing through the transition surface 204, thereby pushing the fixing member 306 toward the lamp housing 500. Finally, the fixing block 307 passes through the fixing groove 501 and extends out of the lamp housing 500. The fixing block 307 can be used to fix the lamp to the mounting structure, for example, by snapping the fixing block 307 to the mounting structure or by mechanically locking the fixing block 307 to the mounting structure.

[0050] Because the second abutment surface 205, the second release surface 206, the third abutment surface 303, and the guide surface 304 are respectively set as inclined surfaces, the adjusting member 200 will also rotate itself during axial movement. After the second abutment surface 205 of the adjusting member rises from the release groove 305 in the through hole, it gradually transitions to abutting against the third abutment surface 303 in the through hole. After fixing, the pressing part 400 is released, and the adjusting member 200 is subjected to the reaction force of the first elastic member 102. The second abutment surface 205 of the adjusting member falls on the third abutment surface 303 in the through hole, and is stopped by the third abutment surface 303 and the step between the third abutment surface 303 and the guide surface 304.

[0051] The adjusting member 200 is subjected to forces from the first elastic member 102 and the pressing part 400 in the axial direction of the through hole, and to a force from the fixing member 306 in the radial direction of the through hole, making it prone to swaying during movement. By inserting a directional post 207, which extends axially relative to the second abutment surface 205 and the second release surface 206, into the directional hole 402, the adjusting member 200 can be prevented from swaying during axial movement and its own rotation, ensuring smooth movement. After the directional post 207 is inserted into the directional hole 402, the first abutment protrusion 401 is aligned axially with the second abutment surface 205, applying pressing force to the pressing part 400, thus forming an abutment between the first abutment protrusion 401 of the pressing part 400 and the second abutment surface 205 of the adjusting member 200.

[0052] Since the adjusting member 200 moves both axially and rotates on its own, setting the transition surface 204 as a smooth conical surface can make the second abutting protrusion 309 abut more smoothly when it moves between the first release surface 202 and the first abutting surface 203, thus preventing the fixing member 306 from getting stuck or jumping during movement.

[0053] The two sides of the fixing member 306 are subjected to the forces of the adjusting member 200 and the second elastic member 308 in the radial direction of the through hole, which makes it prone to non-directional movement during operation. The second directional block 310 engaging with the second directional groove 311 ensures the fixing member 306 moves in a directional and stable manner, and that the fixing block 307 is always aligned with the direction of the fixing groove 501. Furthermore, the radial width difference between the second directional groove 311 and the second directional block 310 is greater than or equal to the radial width difference between the first release surface 202 and the first abutment surface 203. This means that the second directional groove 311 not only provides orientation for the fixing member 306 but also provides a continuous fixing function. That is, during the movement of the fixing member 306, the second directional block 310 is always engaged with the second directional groove 311, making it difficult to disengage and ensuring long-term stable and reliable use.

[0054] When used to disassemble a lamp, this invention applies an upward pressing force to the pressing member 404 again, transforming it into applying an upward pressing force to the pressing part 400. The first abutting protrusion 401 of the pressing part 400 abuts against the second abutting surface 205 of the adjusting member 200, pushing the adjusting member 200 to move upward along the axial direction of the through hole. Since the second abutting surface 205, the second release surface 206, the third abutting surface 303, and the guide surface 304 are respectively set as inclined surfaces, the adjusting member 200 will also rotate itself during axial movement. After rising from the third abutting surface 303 in the through hole, the second abutting surface 205 of the adjusting member 200 gradually transitions to abutting against the guide surface 304 in the through hole, and after abutting against the guide surface 304 in the through hole, it is guided into the release groove 305 in the through hole.

[0055] After the pressing part 400 is released, since there is no contact between the second abutment surface 205 and the release groove 305, the adjusting member 200 moves downward along the axial direction of the through hole under the reaction force of the first elastic member 102. The second release surface 206 of the adjusting member 200 falls on the third abutment surface 303 in the through hole, and is stopped by the third abutment surface 303 and the step between the third abutment surface 303 and the guide surface 304.

[0056] Simultaneously, the second abutting protrusion 309 gradually transitions from abutting the first abutting surface 203 to abutting the first release surface 202 via the transition surface 204. The fixing member 306, subjected to the reaction force of the second elastic member 308, moves away from the lamp housing 500. Finally, the fixing block 307 passes through the fixing groove 501 and retracts into the lamp housing 500, allowing the lamp to be removed from the mounting structure.

[0057] This invention allows the fixing block 307 to extend out of and retract into the lamp housing sequentially by pressing the pressing part 400. The fixing mechanism mechanically locks or unlocks the block, repeating this cycle repeatedly. This makes assembly and disassembly simple and convenient, replacing magnetic installation. It eliminates the need for magnetic components, avoiding interference with the electrical components inside the lamp and ensuring the lamp's power supply and signal transmission performance. Once installed and fixed, the lamp remains stable for a long time, and the lamp housing will not deform elastically.

[0058] Furthermore, this invention houses almost all the main components of the fixing mechanism, except for the lamp housing, within the lamp housing 500, requiring only a simple fixing groove 501 on the lamp housing 500. Simultaneously, the lamp mounting structure only needs a simple fixing position to secure the fixing block 307. Therefore, there is no need to design the lamp housing and mounting structure as corresponding connecting recesses and protrusions, thus not restricting the external shape of the lamp and mounting structure, allowing for various aesthetically pleasing designs. The application range is also greatly expanded, making it suitable for the installation and fixing of lamps of various types and scenarios.

[0059] Example 2

[0060] The difference between this embodiment and Embodiment 1 is that in this embodiment, the outer wall of one end of the pressing part 400 located within the through hole 302 is provided with first directional blocks 403 distributed circumferentially, and the inner wall of the through hole 302 is provided with first directional grooves 313 distributed circumferentially. The number of first directional blocks 403 is equal to the number of first directional grooves 313, and the first directional blocks 403 are respectively engaged in the first directional grooves 313. The dimensions of the first directional blocks 403 and the first directional grooves 313 correspond in the radial and circumferential directions, so that the first directional blocks 403 can be engaged in the first directional grooves 313 to provide orientation for the movement of the pressing part 400. Moreover, it can provide orientation in the entire circumferential direction, which can prevent the pressing part 400 from swinging or rotating left and right during axial movement, ensuring smooth movement.

[0061] The other structures are the same as in Example 1.
