Abstract
Description
Technical Field
[0001] This invention relates to the field of medical lighting technology, and in particular to an adsorption-type lighting device. Background Technology
[0002] With the continuous development of minimally invasive and precision surgical techniques, surgical expanders are playing an increasingly important role in surgical procedures. Existing surgical expanders are mainly made of metal materials such as stainless steel or titanium alloys, possessing good mechanical strength and biocompatibility. They can stably maintain the open state of the surgical area, providing ample space for surgical operations.
[0003] In existing technologies, surgical area lighting mainly relies on two methods: one is the use of independent surgical shadowless lamps or auxiliary lighting equipment, which usually require specialized brackets for fixation, and the position adjustment is relatively cumbersome; the other is that medical staff wear head-mounted lighting devices. Although this method frees up their hands, the lighting angle is limited by the head position and posture. Especially during long surgeries, as the surgical site deepens or the patient's position changes, medical staff need to constantly adjust their posture to obtain the best field of vision. At this time, fixed lighting equipment is difficult to follow the movement of the surgical area in real time, and head-mounted lighting often cannot provide ideal lighting effects due to angle limitations.
[0004] Precise lighting in the surgical area is crucial for surgical safety and operational efficiency. Existing designs that separate the lighting from the expander require medical staff to frequently adjust the lighting during surgery. This not only increases the complexity of the surgical procedure but may also lead to insufficient lighting affecting the surgical field of vision, thereby reducing surgical accuracy and prolonging surgical time.
[0005] Therefore, there is an urgent need to provide an adsorption-type lighting device to address the problems existing in the prior art to some extent. Summary of the Invention
[0006] The purpose of this invention is to provide an adsorption-type lighting device to solve, to some extent, the problem that metal expanders lack lighting modules and require additional lighting equipment to supplement insufficient illumination in the surgical cavity.
[0007] The present invention provides an adsorption-type lighting device for increasing the lighting capability of a metal expander, comprising a main adsorption component and a lighting component; the main adsorption component includes a main housing, the main housing having a mounting cavity, and the lighting component disposed within the mounting cavity; the main housing is made of a soft material, and at least the top surface of the main housing is made of a transparent material to form a light-emitting surface; the bottom surface of the main housing is provided with a first sealing lip, the first sealing lip being arranged circumferentially along the bottom surface of the main housing to form a first sealing space.
[0008] The adsorption-type lighting device provided in this application further includes a secondary adsorption component, which includes a secondary housing made of a soft material. The secondary housing has a support groove, and the first sealing lip can be adsorbed into the support groove. A second sealing lip is formed on the side of the secondary housing opposite to the support groove. The second sealing lip is arranged circumferentially along the bottom surface of the secondary housing to form a second sealing space. A connecting hole is formed on the secondary housing, and the connecting hole connects the first sealing space and the second sealing space.
[0009] Specifically, a third sealing lip is formed on the bottom surface of the sub-shell. The third sealing lip is arranged circumferentially along the bottom surface of the sub-shell and is located inside the second sealing lip. The third sealing lip is spaced apart from the second sealing lip.
[0010] Furthermore, the height of the second sealing lip is greater than the height of the third sealing lip, or the height of the second sealing lip is the same as the height of the third sealing lip, or the height of the second sealing lip is less than the height of the third sealing lip; the spacing between the second sealing lip and the third sealing lip is greater than the maximum height of the second sealing lip and the third sealing lip.
[0011] Furthermore, a lower pressure rib is formed on the bottom surface of the main housing. The lower pressure rib is arranged circumferentially along the bottom surface. The lower pressure rib is located in the inner ring of the first sealing lip and is spaced apart from the first sealing lip. The height of the lower pressure rib is less than the height of the first sealing lip. Multiple venting grooves are arranged circumferentially on the lower pressure rib.
[0012] The lighting component includes a light strip and a light bead. The mounting cavity includes a first positioning cavity and a second positioning cavity. The width of the first positioning cavity is greater than the width of the second positioning cavity, and the height of the first positioning cavity is less than the height of the second positioning cavity. The light strip is disposed in the first positioning cavity, so that the light strip is correspondingly located in the second positioning cavity.
[0013] Specifically, a first extension is formed at one end of the main housing, a positioning post is formed on the first extension, and a positioning hole is formed on the light strip corresponding to the position of the positioning post. The positioning post passes through the positioning hole to position the light strip in the horizontal direction.
[0014] Furthermore, a mating groove is formed at the end of the main housing away from the first extension. The first extension is T-shaped. In two adjacent main housings, the two ends of the first extension of one main housing are respectively inserted into the mating groove of the other main housing, so that the two main housings are connected.
[0015] Furthermore, a mating boss is formed on the lower surface of one end of the light strip corresponding to the positioning post, a pair of contact points are formed on the upper surface of one end of the light strip corresponding to the mating groove, and an alignment hole is formed on the end of the light strip forming the pair of contact points. The positioning post passes through the alignment hole and presses the mating boss onto the pair of contact points.
[0016] Furthermore, a second extension is formed on the top surface of the main housing at the end away from the first extension. A first support block and a second support block are provided at the end of the second extension away from the main housing. The first support block and the second support block are arranged opposite to each other on both sides of the main housing along the width direction of the main housing, and the first support block and the second support block are spaced apart from the main housing. A first limiting rib is provided on the first support block, one end of which is connected to the first support block and the other end of which is connected to the main housing. A second limiting rib is provided on the second support block, one end of which is connected to the second support block and the other end of which is connected to the main housing, so as to form the mating groove.
[0017] Compared with existing technologies, the adsorption-type lighting device provided by this invention has the following advantages: The present invention provides an adsorption-type lighting device, comprising a main adsorption component and a lighting component; the main adsorption component includes a main housing, the main housing having an installation cavity, and the lighting component being disposed within the installation cavity; the main housing is made of a soft material, and at least the top surface of the main housing is made of a transparent material to form a light-emitting surface; the bottom surface of the main housing is provided with a first sealing lip, the first sealing lip being arranged circumferentially along the bottom surface of the main housing to form a first sealing space.
[0018] Compared with existing technologies, the adsorption-type lighting device provided by this invention has the following advantages: The adsorption-type lighting device provided by the present invention can provide a mounting base for the lighting component through the mounting cavity formed by the main housing. Since at least the top surface of the main housing in this application is made of transparent material, a light-emitting surface can be formed. When the lighting component is powered on and emits light, the light can be emitted outward through the light-emitting surface to realize the lighting function.
[0019] Correspondingly, since the bottom surface of the main housing is provided with a first sealing lip, and the first sealing lip is arranged circumferentially along the bottom surface of the main housing to form a first sealing space, in practical applications, pressing the main housing can deform the first sealing lip, thereby reducing the volume of the first sealing space. After the pressure is lost, the first sealing lip will adhere to the surface to be fixed, thus enabling the integration of the overall structure with the metal expander. When illumination is required, the illumination component is turned on, and light shines from the top surface to illuminate the surgical area.
[0020] Since the adsorption-type lighting device provided in this application, when combined with the metal expander, can be closer to the surgical area, it can provide better lighting effects, thus eliminating the need for medical staff to wear headlamps or add further lighting equipment.
[0021] Understandably, when dealing with flat metal expanders, the main housing is made of a soft material, while the top surface can be made of a transparent hard material, such as a transparent plastic sheet. The transparent plastic sheet on the top surface can be connected to the main housing through methods such as heat fusion. However, in this approach, the main adsorption component provided in this application is limited to use in flat metal expanders.
[0022] However, since there are many types of metal expanders, including those with curved surfaces, the main housing is made of soft materials, such as rubber or silicone, which not only has a certain degree of hardness but also better fits the curved surface of the metal expander, achieving a stable connection.
[0023] It should be added that, due to the smaller thickness of the first sealing lip, i.e., the thinner first sealing lip, it has a better deformation effect than the main shell, thereby enabling the adsorption function mentioned above.
[0024] When dealing with curved metal expanders, the top light-transmitting part also needs to use the same soft material as the main shell, and further requires a transparent soft material, such as transparent silicone or transparent rubber, so that light can pass through and can also deform to match the curved metal expander of the main shell.
[0025] Furthermore, the lighting component provided in this application uses an existing LED light strip, including the light strip and LED beads. The light strip is flexible and deformable, and the LED beads are arranged on the light strip. One end of the mounting cavity is open, thereby enabling the light strip to be connected to an external power source and realizing the light-emitting function of the lighting component. Moreover, since the main housing provided in this application is made entirely of a soft material, it can better adapt to different types of metal expanders and also, to a certain extent, avoid the risk of scratching human tissue during surgery.

[0038] like Figures 1-5 As shown, the present invention provides an adsorption-type lighting device, including a main adsorption component and a lighting component; the main adsorption component includes a main housing 1, the main housing 1 having a mounting cavity 101, and the lighting component being disposed within the mounting cavity 101; the main housing 1 is made of a soft material, and at least the top surface of the main housing 1 is made of a transparent material to form a light-emitting surface; the bottom surface of the main housing 1 is provided with a first sealing lip 102, and the first sealing lip 102 is arranged circumferentially along the bottom surface of the main housing 1 to form a first sealing space 1021.
[0039] Compared with existing technologies, the adsorption-type lighting device provided by this invention has the following advantages: The adsorption-type lighting device provided by the present invention can provide a mounting base for the lighting component through the mounting cavity 101 formed by the main housing 1. Since at least the top surface of the main housing 1 in this application is made of transparent material, a light-emitting surface can be formed. When the lighting component is powered on and emits light, the light can be emitted outward through the light-emitting surface to realize the lighting function.
[0040] Correspondingly, since the bottom surface of the main housing 1 is provided with a first sealing lip 102, and the first sealing lip 102 is arranged circumferentially along the bottom surface of the main housing 1 to form a first sealing space 1021, in actual application, pressing the main housing 1 can deform the first sealing lip 102, thereby reducing the volume of the first sealing space 1021. After the pressure is lost, the first sealing lip 102 will adhere to the surface to be fixed, thereby realizing the combination of the overall structure and the metal expander. When lighting is required, the lighting component is turned on, and light shines from the top surface to illuminate the surgical area.
[0041] Since the adsorption-type lighting device provided in this application, when combined with the metal expander, can be closer to the surgical area, it can provide better lighting effects, thus eliminating the need for medical staff to wear headlamps or add further lighting equipment.
[0042] Understandably, when dealing with a flat metal expander, the main housing 1 is made of a soft material, while the top surface can be made of a transparent hard material, such as a transparent plastic sheet. The transparent plastic sheet on the top surface can be connected to the main housing 1 by means of heat fusion or other methods. However, in this approach, the main adsorption component provided in this application is limited to use in flat metal expanders.
[0043] However, since there are many types of metal expanders, including those with curved surfaces, the main housing 1 is made of soft materials, such as rubber or silicone, which can have a certain degree of hardness and better fit the curved surface of the metal expander to achieve a stable connection.
[0044] It should be noted that, since the first sealing lip 102 is thinner, it has a better deformation effect than the main housing 1, thereby enabling the adsorption function described above.
[0045] When facing the curved metal expander, the light-transmitting part on the top surface also needs to use the same soft material as the main shell 1, and further requires a transparent soft material, such as transparent silicone or transparent rubber, so that light can pass through and can also deform to match the curved metal expander of the main shell 1.
[0046] Furthermore, the lighting component provided in this application uses an existing LED light strip 3, including the light strip 3 and LED beads 4. The light strip 3 is bendable and deformable, and the LED beads 4 are arranged on the light strip 3. One end of the mounting cavity 101 is open, thereby enabling the light strip 3 to be connected to an external power source and realizing the light-emitting function of the lighting component. Moreover, since the main housing 1 provided in this application is made entirely of soft material, it can better adapt to different types of metal expanders and can also, to a certain extent, avoid the risk of scratching human tissue during surgery.
[0047] Optionally, such as Figures 1-5 As shown, the adsorption-type lighting device provided in this application further includes a secondary adsorption component, which includes a secondary housing 2. The secondary housing 2 is made of a soft material and has a support groove 201. The first sealing lip 102 can be adsorbed into the support groove 201. A second sealing lip 203 is formed on the side of the secondary housing 2 facing away from the support groove 201. The second sealing lip 203 is arranged circumferentially along the bottom surface of the secondary housing 2 to form a second sealing space 205. A connecting hole 202 is formed on the secondary housing 2, which connects the first sealing space 1021 and the second sealing space 205.
[0048] The adsorption-type lighting device provided by the present invention also includes a secondary adsorption component, which includes a secondary housing 2. The secondary housing 2 is made of a soft material, such as silicone or rubber, and is similar to or the same as the material of the main housing 1 to ensure good fit and deformability.
[0049] The secondary housing 2 has a support groove 201, and the first sealing lip 102 of the main adsorption mechanism can be adsorbed into the support groove 201, realizing a detachable connection between the main adsorption mechanism and the secondary adsorption component. This design allows for flexible combination of adsorption lighting devices to adapt to different surgical scenarios.
[0050] Correspondingly, a second sealing lip 203 is formed on the side of the sub-shell 2 facing away from the bearing groove 201. The second sealing lip 203 is arranged circumferentially along the bottom surface of the sub-shell 2, forming a second sealing space 205. A connecting hole 202 is also formed on the sub-shell 2, connecting the first sealing space 1021 and the second sealing space 205. In practical applications, when the main adsorption mechanism and the sub-adsorption component are jointly adsorbed on the metal expander, pressing the main shell 1 can apply pressure to the sub-shell 2, thereby deforming the second sealing lip 203 and partially expelling the gas in the second sealing space 205, forming initial positioning. The connecting hole 202 connects the air pressure of the two sealing spaces. When the pressure on the main shell 1 is no longer applied, the main shell 1 rebounds, thereby creating a negative pressure in the first sealing space 1021 to draw air out of the second sealing space 205, creating a negative pressure in the second sealing space 205, thereby enhancing the overall adsorption stability. This double-sealing design is particularly suitable for curved or uneven metal expander surfaces, effectively preventing detachment and improving the reliability of the lighting device.
[0051] Preferably, such as Figure 1 As shown, in some embodiments, the main housing 1 and the sub-housing 2 are provided with connecting pieces 5 on their sides. Accordingly, the connecting pieces 5 in this application can be integrated with the main housing 1 and the sub-housing 2, thereby enabling the main housing 1 and the sub-housing 2 to form an integral structure without the need for positioning between the main and sub-housing, thus ensuring alignment accuracy.
[0052] However, the connecting piece 5 can also be a separate structure from the main housing 1 and the sub-housing 2. Of course, in this way, slots need to be formed at corresponding positions on the sides of the main housing 1 and the sub-housing 2. By plugging in, the connecting piece 5 can be connected to the main housing 1 and the sub-housing 2 to realize the connection between the main and sub-housing.
[0053] Optionally, such as Figures 1-5 As shown, the bottom surface of the sub-shell 2 in this application is further provided with a third sealing lip 204. The third sealing lip 204 is arranged circumferentially along the bottom surface of the sub-shell 2 and is located inside the second sealing lip 203. The third sealing lip 204 and the second sealing lip 203 are spaced apart.
[0054] Based on the above scheme, a third sealing lip 204 is also formed on the bottom surface of the sub-shell 2. The third sealing lip 204 is arranged circumferentially along the bottom surface of the sub-shell 2 and is located inside the second sealing lip 203, spaced apart from the second sealing lip 203. This multi-layer sealing lip structure increases the number of sealing points, and when adsorbed onto the metal expander, the third sealing lip 204 can further improve the sealing effect.
[0055] Preferably, in this application, the contact position between the first sealing lip 102 formed on the main housing 1 and the sub-housing 2 is located between the second sealing lip 203 and the third sealing lip 204, so that the second sealing lip 203 and the third sealing lip 204 can be subjected to more uniform force during the pressing of the main housing 1, thus ensuring the sealing effect.
[0056] Understandably, the spacing between the third sealing lip 204 and the second sealing lip 203 avoids mutual interference, ensuring that each sealing lip can deform independently to adapt to surfaces with different curvatures.
[0057] Optionally, the height of the second sealing lip 203 in this application is greater than the height of the third sealing lip 204, or the height of the second sealing lip 203 is the same as the height of the third sealing lip 204, or the height of the second sealing lip 203 is less than the height of the third sealing lip 204; the spacing between the second sealing lip 203 and the third sealing lip 204 is greater than the maximum height of the second sealing lip 203 and the third sealing lip 204.
[0058] In this embodiment, the height of the second sealing lip 203 and the height of the third sealing lip 204 can be configured differently: for example, the height of the second sealing lip 203 is greater than the height of the third sealing lip 204, or the two are the same height, or the height of the second sealing lip 203 is less than the height of the third sealing lip 204.
[0059] This highly variable design allows for the selection of the optimal sealing combination based on the surface characteristics of the metal expander, such as smoothness or curvature. For example, a higher sealing lip provides a better fit for rough surfaces, while a lower sealing lip is sufficient to ensure adsorption for smooth surfaces. Therefore, by using three different height combinations, it is possible to adapt to more complex expander surface conditions and improve adsorption capacity.
[0060] Furthermore, the spacing between the second sealing lip 203 and the third sealing lip 204 is greater than their maximum height dimensions. This prevents the sealing lips from contacting each other during deformation, ensuring independent operation and enhancing sealing reliability. In practical applications, this design reduces the risk of leakage and makes the adsorption more robust.
[0061] Preferably, such as Figure 3As shown, the bottom surface of the main housing 1 in this application is also formed with a lower pressure rib 103. The lower pressure rib 103 is arranged circumferentially along the bottom surface. The lower pressure rib 103 is located in the inner ring of the first sealing lip 102 and is spaced apart from the first sealing lip 102. The height of the lower pressure rib 103 is less than the height of the first sealing lip 102.
[0062] By further forming a lower pressure rib 103 on the bottom surface of the main housing 1, and the lower pressure rib 103 is arranged circumferentially along the bottom surface of the main housing 1, located in the inner ring of the first sealing lip 102 and spaced apart from the first sealing lip 102, and the height of the lower pressure rib 103 is less than the height of the first sealing lip 102, when the main housing 1 is pressed, the first sealing lip 102 first contacts the surface of the bearing groove 201, forming an initial positioning between the main housing 1 and the sub-housing 2. As the pressure is further applied, the lower pressure rib 103 contacts the surface of the bearing groove 201. Since the structure of the lower pressure rib 103 is more stable, it can guide the second sealing lip 203 and the third sealing lip 204 to produce uniform deformation, and the sub-housing 2 and the expander surface are initially positioned by the second sealing lip 203 and the third sealing lip 204.
[0063] Understandably, because the structure of the lower pressure rib 103 is more stable, it has a faster rebound effect compared to the sealing lip. Therefore, when the main housing 1 loses its downward pressure, the lower pressure rib 103 will rebound quickly, thereby creating a negative pressure in the second sealing space 205 and completing the stable adsorption between the secondary housing 2 and the outer surface of the expander.
[0064] The pressure rib 103 in this application can be a continuous annular convex rib structure formed along the circumference, thereby forming a stable and uniform downward pressure and ensuring the pressure application effect. However, it can also be a column structure with multiple protrusions spaced apart in the circumference, thereby achieving the same pressure application. At the same time, due to the multiple protrusions in the circumference, an air gap can also be formed, thereby enabling the rapid discharge of internal air.
[0065] Preferably, the lower pressure rib 103 in this application is provided with a plurality of ventilation grooves 1031 spaced apart in the circumferential direction, such as... Figure 3 As shown, there are four ventilation slots 1031 in this application, which are arranged in pairs opposite each other on the two long sides of the lower pressure rib 103. Thus, the ventilation slots 1031 can realize the entry and exit of gas, improve the adsorption effect, and ensure the stability of the main shell 1.
[0066] like Figures 1-5As shown, the lighting component provided in this application includes a light strip 3 and a lamp bead 4. The mounting cavity 101 includes a first positioning cavity 1011 and a second positioning cavity 1012. The width of the first positioning cavity 1011 is greater than the width of the second positioning cavity 1012, and the height of the first positioning cavity 1011 is less than the height of the second positioning cavity 1012. The light strip 3 is disposed in the first positioning cavity 1011, so that the light strip 3 is correspondingly located in the second positioning cavity 1012.
[0067] The lighting component in this application includes a light strip 3 and LED beads 4. The light strip 3 is a flexible LED light strip 3, which can be bent to adapt to different shapes. The mounting cavity 101 includes a first positioning cavity 1011 and a second positioning cavity 1012, wherein the width of the first positioning cavity 1011 is greater than the width of the second positioning cavity 1012, and the height of the first positioning cavity 1011 is less than the height of the second positioning cavity 1012. The light strip 3 is disposed in the first positioning cavity 1011, so that the light strip 3 is correspondingly located in the second positioning cavity 1012. This cavity design fixes the light strip 3 in the first positioning cavity 1011 to prevent displacement, while the second positioning cavity 1012 provides sufficient space to accommodate the LED beads 4, ensuring that the light is emitted uniformly from the top surface.
[0068] It is understandable that, since the main housing 1 has a downward pressure rib 103 and a first sealing lip 102, and the light-emitting surface of the main housing 1 needs to be pressed down during actual operation, the second positioning cavity 1012 and the first sealing space 1021 corresponding to the second positioning cavity 1012 in space can provide sufficient buffering for the lighting component, ensuring the stability and lifespan of the lighting component.
[0069] It should be noted that one end of the light strip 3 in this application has a connecting wire, which can be further connected to an external power source through an electric wire to meet the power supply requirements of the lighting components.
[0070] Optionally, such as Figures 1-5 As shown, a first extension 105 is formed at one end of the main housing 1 in this application. A positioning post 104 is formed on the first extension 105. A positioning hole 303 is formed on the light strip 3 at the position corresponding to the positioning post 104. The positioning post 104 passes through the positioning hole 303 to position the light strip 3 in the horizontal direction.
[0071] During installation, the positioning post 104 formed on the first extension 105 passes through the positioning hole 303, so that the light strip 3 is accurately positioned in the horizontal direction, preventing the light strip 3 from sliding or twisting during use. The positioning post 104 simplifies the assembly process, improves production efficiency, and ensures the stability of the position of the lighting components.
[0072] Optionally, such as Figures 1-5As shown, the main housing 1 in this application has a mating groove 1065 formed at the end away from the first extension 105. The first extension 105 is T-shaped. In two adjacent main housings 1, the two ends of the first extension 105 of one main housing 1 are respectively inserted into the mating groove 1065 of the other main housing 1, so that the two main housings 1 are connected.
[0073] In some embodiments, due to the need for a larger illumination range, this application further optimizes the structure of the main housing 1, forming a mating groove 1065 at the end of the main housing 1 away from the first extension 105. Since the first extension 105 in this application is T-shaped, it enables rapid connection of the two main housings 1. That is, when a further increase in illumination range is needed, the end of the main housing 1 forming the first extension 105 is inserted into the mating groove 1065 formed by the other main housing 1, thereby achieving rapid connection of the two housing components. Furthermore, the structure provided by this application allows for the docking of multiple lighting devices, thereby adapting to different lighting needs and improving compatibility with surgical procedures.
[0074] It is understandable that, since the overall thickness of the adsorption-type lighting device provided in this application is relatively small, not exceeding 5mm, in order to achieve rapid docking and circuit connection of multiple light strips 3, a docking boss 301 is formed on the lower surface of one end of the light strip 3 corresponding to the positioning post 104, a pair of contact points 302 is formed on the upper surface of one end of the light strip 3 corresponding to the mating groove 1065, and an alignment hole 304 is formed on the end of the light strip 3 forming the pair of contact points 302. The positioning post 104 passes through the alignment hole 304 to press the docking boss 301 onto the pair of contact points 302.
[0075] In this application, the mating boss 301 is made of a conductive metal material, and correspondingly, the contact point 302 is also made of a conductive metal material. When it is necessary to increase the length of the light strip 3, the mating boss 301 can be brought into contact with the contact point 302. Since one end of the light strip 3 in this application forms the mating boss 301 and the other end forms the contact point 302, and the position where the contact point 302 is formed also has an alignment hole 304, when the two light strips 3 are connected end to end, the positioning post 104 can pass through the positioning hole 303 and the alignment hole 304 at the same time, and press the ends of the two light strips 3 together through the first extension 105, so that the mating boss 301 and the contact point 302 are in contact, ensuring stable circuit conduction.
[0076] like Figures 1-5As shown, this application further provides an embodiment for achieving quick connection of the main housing 1, namely, a second extension 106 is formed on the top surface of the main housing 1 at the end away from the first extension 105. A first support block 1061 and a second support block 1063 are provided at the end of the second extension 106 away from the main housing 1. The first support block 1061 and the second support block 1063 are arranged opposite to each other on both sides of the main housing 1 along the width direction of the main housing 1, and the first support block 1061 and the second support block 1063 are spaced apart from the main housing 1. A first limiting rib 1062 is provided on the first support block 1061, one end of the first limiting rib 1062 is connected to the first support block 1061, and the other end is connected to the main housing 1. A second limiting rib 1064 is provided on the second support block 1063, one end of the second limiting rib 1064 is connected to the second support block 1063, and the other end is connected to the main housing 1 to form a mating groove 1065.
[0077] It is understood that one end of the main housing 1 provided in this application forms a first extension 105, and the first extension 105 is T-shaped. The other end of the main housing 1 can form a mating groove 1065 corresponding to the shape of the T-shaped first extension 105 through the first support block 1061, the first limiting rib 1062, the second support block 1063, and the second limiting rib 1064. This enables the first extension 105 to be inserted into the mating groove 1065, thereby achieving quick docking of two adjacent main housings 1.
[0078] Preferably, the first limiting rib 1062 and the second limiting rib 1064 in this application are made of soft material and have a small thickness. Therefore, they can produce a large range of deformation. In actual assembly, one end of the T-shaped first extension 105 can be inserted into the mating groove 1065 formed on one side of the first limiting rib 1062. Then, by pulling the second limiting rib 1064 on the other side, the second limiting rib 1064 is deformed, which expands the space of the formed mating groove 1065. This makes it easier for the other end of the first extension 105 to enter the mating groove 1065 on that side. After releasing the second limiting rib 1064, the second limiting rib 1064 is reset, thereby restricting the first extension 105 within the formed mating groove 1065. This enables a quick connection between the two housings, allowing the overall device to meet different lighting needs.
[0079] It should be further noted that the adsorption-type lighting device provided in this application can be further equipped with a power supply component. The power supply component includes a power supply housing, a battery, a control board, and a switch. The power supply housing has the same structure as the main housing 1 mentioned above, so it can be directly connected to the main housing 1. The battery and control board are located inside the power supply housing, so as to provide a stable power supply for the light strip 3. Furthermore, the switch can be integrated outside the power supply housing and connected to the control board circuitry, thereby enabling the switching operation of the lighting component. Of course, the power supply housing is equipped with a socket, so that by integrating a plug into the end of the light strip 3, the plug and socket can be quickly connected after the power supply housing is connected to the main housing 1.
[0080] The power supply components can be further integrated with functions such as charging ports and screen displays, all of which can be achieved using existing charging and screen display structures, and will not be elaborated further here.
[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
