Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and particularly to a telescopic spotlight. Background Art

[0002] Spotlights are widely used in life. Generally, they refer to a kind of lighting fixture installed on the ceiling, mainly used in various indoor space places, such as private houses, hotel dining, commercial stores, supermarkets, etc.

[0003] Currently, most existing spotlights adopt an embedded installation method, that is, the spotlight is embedded into the ceiling to enhance the spatial aesthetics and light directivity of the indoor environment. However, due to the fixed structure of the spotlight itself, the illumination direction of the embedded spotlight is fixed, and the spotlight after installation cannot adjust the irradiation angle. Therefore, when it is necessary to change the illumination direction of the spotlight, the spotlight can only be disassembled, adjusted in angle, and reinstalled. Although some existing spotlights have a function of rotational adjustment, due to the narrow movable space of the spotlight caused by the embedded installation, the spotlight still cannot rotate the angle or can only rotate a small angle, which is difficult to meet the actual needs. Therefore, the spotlight still can only be disassembled, adjusted in angle, and reinstalled. Therefore, after the existing spotlight is embedded, it is difficult to adjust the illumination direction, which reduces the practicability of the spotlight and makes it difficult for the spotlight to meet the usage requirements of different scenarios. Summary of the Invention

[0004] This application provides a telescopic spotlight, the purpose of which is to enable the spotlight to still be able to adjust the angle after being embedded, so that the illumination angle of the spotlight can be adjusted, improving the practicability of the spotlight and increasing the applicable range of the spotlight.

[0005] A telescopic spotlight provided by this application adopts the following technical solutions: A telescopic spotlight includes an installation mechanism, an adjustment mechanism, and a spotlight main body; the installation mechanism includes an installation seat and a telescopic sleeve, the installation seat is sleeved outside the telescopic sleeve, the telescopic sleeve is coaxially arranged with the spotlight main body, and the telescopic sleeve is sleeved outside the spotlight main body, and the telescopic sleeve is movably connected to the spotlight main body; the adjustment mechanism includes a piston plate, a first-level rotating connector, and a second-level rotating connector, the piston plate is inserted into the telescopic sleeve, the telescopic sleeve is axially slidably connected to the piston plate along its own axis, the piston plate, the first-level rotating connector, the second-level rotating connector, and the spotlight main body are sequentially connected, the rotation axis of the first-level rotating connector is collinear with the axis of the telescopic sleeve, and the rotation axis of the second-level rotating connector is perpendicular to the rotation axis of the first-level rotating connector.

[0006] By adopting the above technical solution, the mounting base in the mounting mechanism cooperates with the telescopic sleeve to ensure the stable installation of the spotlight body while allowing the spotlight body to axially expand and contract along the telescopic sleeve.

[0007] In the adjusting mechanism, the sliding connection of the piston plate in the telescopic sleeve, combined with the arrangement of the first-level rotating connector and the second-level rotating connector, enables the spotlight body to slide out of the telescopic sleeve. After the spotlight body slides out of the telescopic sleeve, the telescopic sleeve no longer has a limiting effect on the spotlight body. At this time, with the cooperation of the first-level rotating connector and the second-level rotating connector, the spotlight body can achieve free rotation at multiple angles.

[0008] This enables the spotlight body to not only adjust its position in the vertical direction but also achieve free rotation at multiple angles. Thus, after the spotlight is embedded in the ceiling, when the illumination angle of the spotlight needs to be adjusted, the spotlight body is pulled out of the telescopic sleeve. At this time, the spotlight body can be adjusted at multiple angles, which can realize the function of adjusting the illumination angle and effectively solve the problem that it is difficult to adjust the illumination angle of the embedded spotlight, improving the practicability and application range of the spotlight.

[0009] Optionally, a guiding member is provided on the piston plate, and a guiding long hole is formed on the telescopic sleeve. The length direction of the guiding long hole is arranged along the axial direction of the telescopic sleeve. The guiding member is inserted and matched with the guiding long hole, and the guiding member is slidably connected with the inner side wall of the guiding long hole.

[0010] By adopting the above technical solution, the cooperation setting of the guiding member and the guiding long hole can effectively prevent the piston plate from rotating in the telescopic sleeve, thereby ensuring that the overall stability of the spotlight body is not affected by the rotation of the piston plate when adjusting the height. At the same time, the sliding connection between the guiding member and the guiding long hole also guides the movement of the piston plate, improving the smoothness and accuracy of the spotlight body during the expansion and contraction process.

[0011] Optionally, the guiding member is detachably connected to the piston plate.

[0012] By adopting the above technical solution, the detachable connection between the guiding member and the piston plate facilitates the disassembly of the guiding member and the piston plate, and further facilitates the removal of the piston plate from the telescopic sleeve, enabling users to conveniently replace or repair the piston plate.

[0013] Optionally, an upper limiting ring is provided at one end of the telescopic sleeve, and a lower limiting ring is provided at the other end. The piston plate is axially located between the upper limiting ring and the lower limiting ring along the telescopic sleeve, and both the upper limiting ring and the lower limiting ring are arranged opposite to the piston plate along the axial direction of the telescopic sleeve.

[0014] By adopting the above technical solution, the upper limit ring and the lower limit ring are respectively located at both ends of the telescopic sleeve. The piston plate is axially limited between the upper limit ring and the lower limit ring along the telescopic sleeve, thereby preventing the piston plate from slipping out of the telescopic sleeve. This design not only improves the stability of the spotlight structure but also ensures that the movement range of the piston plate within the telescopic sleeve is controllable, preventing the piston plate from slipping out of the telescopic sleeve.

[0015] Optionally, the lower limit ring is detachably connected to the telescopic sleeve.

[0016] By adopting the above technical solution, the design of the detachable connection between the lower limit ring and the telescopic sleeve enables the piston plate to be taken out of the telescopic sleeve, facilitating the disassembly, assembly, and maintenance of the piston plate.

[0017] Optionally, a first sealing ring is sleeved outside the piston plate, and the first sealing ring is located between the outer side wall of the piston plate and the inner side wall of the telescopic sleeve.

[0018] By adopting the above technical solution, the first sealing ring is sleeved outside the piston plate and is located between the outer side wall of the piston plate and the inner side wall of the telescopic sleeve. This design increases the friction between the piston plate and the telescopic sleeve, thereby improving the sliding stability of the piston plate and ensuring precise control during the position adjustment of the spotlight body.

[0019] Optionally, it further includes an extension sleeve. The telescopic sleeve and the extension sleeve are coaxially arranged. The telescopic sleeve is sleeved outside the extension sleeve. The extension sleeve is slidably connected to the telescopic sleeve along its own axis. The piston plate is located within the extension sleeve, and the piston plate is slidably connected to the extension sleeve along the axis of the extension sleeve.

[0020] By adopting the above technical solution, the setting of the extension sleeve enables the spotlight body to be further pulled after being pulled out from the telescopic sleeve. At this time, the piston plate drives the extension sleeve to slide within the telescopic sleeve. Therefore, the setting of the extension sleeve can increase the adjustment range of the spotlight body. Moreover, when using the extension sleeve to adjust the position of the spotlight body, the piston plate is located at one end of the extension sleeve. At this time, the extension sleeve does not limit the sliding of the spotlight body, that is, the spotlight body can move up and down and rotate simultaneously, thereby improving the practicality and flexibility of the spotlight.

[0021] Optionally, a plurality of extension sleeves are provided. The inner diameters of the plurality of extension sleeves increase in sequence, and the plurality of extension sleeves are coaxially sleeved in sequence. The telescopic sleeve is sleeved outside the outermost extension sleeve, and the piston plate is located within the innermost extension sleeve; the telescopic sleeve is slidably connected to the adjacent extension sleeve along its own axis, the adjacent two extension sleeves are slidably connected along their own axes, and the piston plate is slidably connected to the adjacent extension sleeve along the axis of the extension sleeve.

[0022] By adopting the above technical solution, several extension sleeves are coaxially plugged in sequence, and the inner diameter of the extension sleeves increases layer by layer, thus forming a multi-layer extension sleeve. Since each extension sleeve can slide along its own axis, a multi-stage telescopic structure can be formed. After the spotlight is embedded, this multi-stage telescopic structure allows the spotlight body to be adjusted to a large extent, thereby meeting the lighting requirements in different scenes.

[0023] Optionally, a mounting ring is provided at one end of the telescopic sleeve, and the mounting ring is coaxially arranged with the telescopic sleeve, and several of the extension sleeves are located inside the mounting ring, and the outermost extension sleeves are slidingly connected or spaced apart with the inner wall of the mounting ring; a support block is provided on the mounting ring, and the length direction of the support block is arranged along the radial direction corresponding to the mounting ring, and the support block is slidingly connected with the mounting ring along its own length direction, and one ends of several of the extension sleeves are in contact with the support block.

[0024] By adopting the above technical solution, the mounting ring and the support block are matched and arranged, during the process of sliding and adjusting the support block, the support block can release the limit on several extension sleeves from the inside to the outside in turn, and can also realize the limit on several extension sleeves from the outside to the inside in turn. This allows the user to freely choose the number of layers of extension sleeves to be used, thereby flexibly adjusting the adjustable range of the spotlight body.

[0025] Optionally, a marble and a spring are provided on the support block, and a clearance hole is opened on the side of the support block facing the mounting ring, the marble and the spring are both located in the clearance hole, the marble is slidably connected to the inner wall of the clearance hole along the axial direction of the clearance hole, the spring is located on the side of the marble away from the mounting ring, one end of the spring is connected to the marble, and the other end is connected to the inner wall of the clearance hole; a plurality of prompt grooves are provided on the mounting ring, and the plurality of prompt grooves are arranged in sequence at intervals along the length direction of the support block, one of the prompt grooves is directly connected to the clearance hole, the marble is inserted into the corresponding prompt groove, and the inner wall of the prompt groove fits with the marble.

[0026] By adopting the above technical solution, marbles and springs are arranged on the support block. The marbles can slide axially in the clearance hole and snap into the prompt groove on the mounting ring under the action of the spring. This design can realize the positioning between the support block and the mounting ring. At the same time, the marbles cooperate with the prompt grooves at different positions to realize the step-by-step unlocking of the extension sleeve. When the user pushes the support block, the marbles will slide out of one prompt groove and enter the next prompt groove, giving a crisp sound feedback, so that the user can clearly perceive the unlocking status of each step. This design improves the convenience of operation and enhances the stability and reliability of the spotlight.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperative design of the telescopic sleeve, the piston plate, the first-level rotating connector and the second-level rotating connector, the spotlight body of the present application can not only adjust its position in the vertical direction, but also achieve free rotation at multiple angles, thus effectively solving the problem that it is difficult to adjust the illumination angle of the recessed spotlight, and improving the practicability and application range of the spotlight.

[0028] 2. Through the cooperative design of the upper limit ring, the lower limit ring, and the guide member and the guide long hole, the present application can prevent the piston plate from falling off the telescopic sleeve, and can also limit the rotation of the piston plate, ensuring the stability and operation accuracy of the spotlight body during the adjustment process; 3. Through the setting of the extension sleeve, the present application can increase the adjustment range of the spotlight body, and enable the spotlight body to lift and rotate at the same time, which can improve the flexibility of the spotlight body.

Detailed implementation mode

[0040] The following will further elaborate on this application with reference to the attached Figure 1 - attached Figure 10 drawings to provide a more detailed description.

[0041] Example 1: A retractable spotlight, referring to Figure 1 the figure, includes an installation mechanism 1, an adjustment mechanism 2 and a spotlight main body 3, and the installation mechanism 1, the adjustment mechanism 2 and the spotlight main body 3 are connected in sequence.

[0042] Referring to Figure 1 and Figure 2 the figure, the installation mechanism 1 includes a mounting base 11 and a telescopic sleeve 12. The telescopic sleeve 12 is arranged vertically, the mounting base 11 is sleeved on the lower end of the telescopic sleeve 12, and two spring clips 111 are symmetrically arranged on the outer side of the mounting base 11.

[0043] Referring to Figure 1 and Figure 2 the figure, the adjustment mechanism 2 includes a piston plate 21, a first-level rotating connector 22 and a second-level rotating connector 23. The piston plate 21, the first-level rotating connector 22, the second-level rotating connector 23 and the spotlight main body 3 are connected in sequence from top to bottom. The piston plate 21 is coaxially arranged with the telescopic sleeve 12, the piston plate 21 is inserted and matched with the telescopic sleeve 12, and the piston plate 21 is slidably connected to the inner side wall of the telescopic sleeve 12 along its own axis.

[0044] The cooperation setting of the mounting base 11 and the spring clip 111 ensures that the spotlight can be installed on the ceiling, thus meeting the installation requirements of the spotlight. Since the piston plate 21 can slide in the telescopic sleeve 12, the position of the piston plate 21 in the vertical direction can be adjusted, and then the position of the spotlight main body 3 in the vertical direction can be changed.

[0045] Referring to Figure 2 and Figure 3, in this embodiment, a plurality of first sealing rings 211 are sleeved outside the piston plate 21, and the first sealing rings 211 are located between the outer side wall of the piston plate 21 and the inner side wall of the telescopic sleeve 12. The arrangement of the first sealing rings 211 increases the friction between the piston plate 21 and the telescopic sleeve 12, thereby increasing the sliding stability of the piston plate 21.

[0046] Referring to Figure 1 and Figure 2 , a contact limiting component 4 is arranged on the telescopic sleeve 12. The contact limiting component 4 includes an upper limiting ring 41 and a lower limiting ring 42. The upper limiting ring 41 is coaxially arranged inside the telescopic sleeve 12, and the outer side wall of the upper limiting ring 41 is fixedly connected to the inner side wall of the telescopic sleeve 12. The lower limiting ring 42 is coaxially arranged at the lower end of the telescopic sleeve 12. The piston plate 21 is located between the upper limiting ring 41 and the lower limiting ring 42 in the vertical direction, and both the upper limiting ring 41 and the lower limiting ring 42 are arranged opposite to the piston plate 21 in the vertical direction.

[0047] The upper limiting ring 41 and the lower limiting ring 42 can limit the piston plate 21 to prevent the piston plate 21 from rushing out of the telescopic sleeve 12.

[0048] Referring to Figure 2 and Figure 3 , the lower limiting ring 42 includes a contact ring 421 and a connecting pipe 422. The contact ring 421 is coaxially arranged at the lower end of the telescopic sleeve 12, and the lower end face of the telescopic sleeve 12 abuts against the contact ring 421. The connecting pipe 422 is located above the contact ring 421. The connecting pipe 422 is coaxially and fixedly connected to the contact ring 421. The connecting pipe 422 is sleeved outside the telescopic sleeve 12, and the connecting pipe 422 is threadedly connected to the telescopic sleeve 12. The mounting seat 11 is sleeved outside the connecting pipe 422, and the mounting seat 11 is in snap-fit connection with the connecting pipe 422.

[0049] Based on the structural arrangement of the lower limiting ring 42, the lower limiting ring 42 on the telescopic sleeve 12 can be disassembled and assembled, which enables the piston plate 21 to be taken out of the telescopic sleeve 12, thereby facilitating the disassembly and assembly of the piston plate 21.

[0050] Referring to Figure 2 and Figure 3 , an anti-rotation guiding component 5 is further arranged between the piston plate 21 and the telescopic sleeve 12. The anti-rotation guiding component 5 includes a guiding member 51. The guiding member 51 is located on the outer side wall of the piston plate 21, and the guiding member 51 is detachably connected to the piston plate 21. A guiding long hole 52 is formed on the side wall of the telescopic sleeve 12. The length direction of the guiding long hole 52 is arranged in the vertical direction. The guiding member 51 is inserted into the guiding long hole 52, and the guiding member 51 is slidably connected to the inner side wall of the guiding long hole 52 in the vertical direction.

[0051] Due to the limitation of the guiding member 51 and the guiding long hole 52, the rotation of the piston plate 21 can be prevented, and at the same time, the movement of the piston plate 21 in the telescopic sleeve 12 can be guided.

[0052] In this embodiment, the guiding member 51 is a screw or a bolt.

[0053] In this embodiment, referring to Figure 2 , the first-level rotating connecting member 22 and the second-level rotating connecting member 23 are both located in the telescopic sleeve 12, and both the first-level rotating connecting member 22 and the second-level rotating connecting member 23 can be inserted into the telescopic sleeve 12. The spotlight main body 3 is coaxially arranged with the telescopic sleeve 12, and the spotlight main body 3 is in plug-in fit with the telescopic sleeve 12. The outer side wall of the spotlight main body 3 is in sliding connection or spaced arrangement with the inner side wall of the telescopic sleeve 12. With such a design, the spotlight main body 3 can be completely retracted into the telescopic sleeve 12, so as to have the function of an embedded spotlight, and at the same time, the adjustable range of the spotlight main body 3 is increased.

[0054] Referring to Figure 1 and Figure 2 , the first-level rotating connecting member 22 includes a first tube 221 and a second tube 222. The first tube 221 is vertically arranged on the piston plate 21, the first tube 221 is coaxially connected with the piston plate 21, and the second tube 222 is coaxially sleeved outside the first tube 221, and the second tube 222 is rotatably connected with the first tube 221.

[0055] Referring to Figure 1 and Figure 2 , the second-level rotating connecting member 23 includes a connecting rod 231 and a connecting shaft 232. The connecting rod 231 is connected to the side wall of the second tube 222, the connecting shaft 232 is arranged on the spotlight main body 3, and the axis of the connecting shaft 232 is perpendicular to the axis of the first tube 221. The end of the connecting rod 231 far from the second tube 222 is sleeved outside the connecting shaft 232, and the connecting pipe 422 is rotatably connected with the connecting shaft 232.

[0056] Referring to Figure 1 and Figure 2 , based on the arrangement of the first tube 221 and the second tube 222, the first tube 221 takes its own axis as the rotation axis between the first tube 221 and the second tube 222; based on the arrangement of the connecting rod 231 and the connecting shaft 232, the connecting shaft 232 takes its own axis as the rotation axis between the connecting rod 231 and the spotlight main body 3. This enables the spotlight main body 3 to be freely adjusted at multiple angles, thereby increasing the adjustable range of the spotlight.

[0057] The implementation principle of the embodiment of this application is as follows: After the downlight is embedded in the ceiling, when it is necessary to adjust the illumination height of the downlight in the vertical direction, the piston plate 21 is pushed. At this time, the downlight body 3 moves up and down in the vertical direction, so that the illumination height of the downlight can be adjusted. When it is necessary to adjust the irradiation angle of the downlight, the piston plate 21 is pushed so that the downlight body 3 completely extends out of the telescopic sleeve 12. At this time, rotating the downlight body 3 can adjust the irradiation angle of the downlight within a large range.

[0058] Embodiment 2: A telescopic downlight, referring to Figure 4 , the difference between this embodiment and Embodiment 1 is that: it further includes an extension sleeve 7. The telescopic sleeve 12 and the extension sleeve 7 are coaxially arranged. The telescopic sleeve 12 is sleeved outside the extension sleeve 7, and the extension sleeve 7 is sleeved outside the piston plate 21. Moreover, both the telescopic sleeve 12 and the piston plate 21 are slidably connected to the extension sleeve 7 along their own axial directions.

[0059] Based on the setting of the extension sleeve 7, the distance that the downlight body 3 moves in the vertical direction can be extended. After the downlight body 3 is completely pulled out of the telescopic sleeve 12, the irradiation angle of the downlight body 3 can be adjusted. If the downlight body 3 is pulled further, the downlight body 3 drives the extension sleeve 7 to slide in the telescopic sleeve 12. At this time, the downlight body 3 can adjust the irradiation angle while moving up and down in the vertical direction.

[0060] Referring to Figure 7 and Figure 8 , in this embodiment, a plurality of extension sleeves 7 are provided. A plurality of extension sleeves 7 are all located between the telescopic sleeve 12 and the piston plate 21. The inner diameters of the plurality of extension sleeves 7 increase in sequence. The plurality of extension sleeves 7 are coaxially sleeved in sequence. Moreover, the telescopic sleeve 12 is sleeved outside the outermost extension sleeve 7, and the piston plate 21 is inserted into the innermost extension sleeve 7. The telescopic sleeve 12, the piston plate 21 and the extension sleeve 7 are all slidably connected to the adjacent extension sleeve 7 in the vertical direction.

[0061] The cooperative setting of the plurality of layers of extension sleeves 7 can further increase the adjustable range of the downlight body 3 in the vertical direction.

[0062] Referring to Figure 6 and Figure 7 , the telescopic sleeve 12 includes a sliding tube 71 and a growth tube 72. The sliding tube 71 and the growth tube 72 are coaxially arranged. The growth tube 72 is located at the lower end of the sliding tube 71. And the growth tube 72 is detachably connected to the sliding tube 71. The outer diameter of the growth tube 72 is smaller than the outer diameter of the sliding tube 71. Moreover, a first limiting ring 73 is coaxially arranged inside the upper end of the sliding tube 71. The first limiting ring 73 is fixedly connected to the inner side wall of the sliding tube 71. A second limiting ring 74 is coaxially arranged inside the lower end of the growth tube 72. The second limiting ring 74 is fixedly connected to the inner side wall of the growth tube 72. And the first limiting ring 73 and the second limiting ring 74 are arranged opposite to each other.

[0063] Referring to Figure 4 and Figure 7 For the positional relationship between the piston plate 21 and the adjacent extension sleeve 7: The piston plate 21 is inserted into the corresponding sliding tube 71 or the extension tube 72. The piston plate 21 is slidably connected to the corresponding sliding tube 71 and the extension tube 72 in the vertical direction, and the piston plate 21 is located between the corresponding first limiting ring 73 and the second limiting ring 74 in the vertical direction. Both the first limiting ring 73 and the second limiting ring 74 are disposed opposite to the piston plate 21 in the vertical direction.

[0064] Referring to Figure 4 and Figure 7 For the positional relationship between two adjacent extension sleeves 7: The sliding tube 71 is coaxially inserted into the adjacent extension sleeve 7, and the sliding tube 71 is slidably connected to the inner side wall of the corresponding extension sleeve 7 in the vertical direction. The inner side wall of the extension tube 72 is spaced from the inner side wall of the corresponding extension sleeve 7. The sliding tube 71 is located between the corresponding first limiting ring 73 and the second limiting ring 74 in the vertical direction. Both the first limiting ring 73 and the second limiting ring 74 are disposed opposite to the corresponding sliding tube 71 in the vertical direction. The extension tube 72 is inserted and matched with the corresponding second limiting ring 74, and the extension tube 72 is slidably connected to the inner side wall of the corresponding second limiting ring 74 in the vertical direction.

[0065] Referring to Figure 2 and Figure 4 For the positional relationship between the telescopic sleeve 12 and the adjacent extension sleeve 7: The sliding tube 71 is slidably connected to the inner side wall of the telescopic sleeve 12 along its own axial direction. The inner side wall of the extension tube 72 is spaced from the inner side wall of the telescopic sleeve 12. The sliding tube 71 is located between the upper limiting ring 41 and the abutting ring 421 in the vertical direction, and both the upper limiting ring 41 and the abutting ring 421 are disposed opposite to the sliding tube 71 in the vertical direction.

[0066] Referring to Figure 7 Based on the structural setting of the extension sleeve 7 and the cooperation between the first limiting ring 73 and the second limiting ring 74, it can prevent two adjacent extension sleeves 7 from slipping off each other, and can also prevent the piston plate 21 in the extension sleeve from slipping off, which ensures the stability of the entire spotlight during use. The detachable connection of the extension sleeve 7 through the sliding tube 71 and the extension tube 72 ensures that the extension sleeve 7 can be disassembled, and further enables the normal disassembly of another extension sleeve 7 or the piston plate 21 in the extension sleeve 7.

[0067] In this embodiment, the sliding tube 71 and the extension tube 72 are connected by threads.

[0068] Referring to Figure 4 and Figure 7, in this embodiment, the first sealing ring 211 is sleeved outside the piston plate 21, and the first sealing ring 211 is located between the outer side wall of the piston plate 21 and the inner side wall of the corresponding extension tube 72 or the inner side wall of the corresponding sliding tube 71.

[0069] Refer to Figure 4 and Figure 7 , in this embodiment, a plurality of second sealing rings 75 are sleeved outside the sliding tube 71, and the second sealing rings 75 are located between the outer side wall of the sliding tube 71 and the inner side wall of the adjacent extension sleeve 7 or the inner side wall of the adjacent telescopic sleeve 12.

[0070] Refer to Figure 4 and Figure 5 , an anti-rotation guiding assembly 5 is provided between the piston plate 21 and the adjacent extension sleeve 7, between two adjacent extension sleeves 7, and between the telescopic sleeve 12 and the adjacent extension sleeve 7.

[0071] Refer to Figure 4 and Figure 5 , the guiding member 51 in the anti-rotation guiding assembly 5 is arranged on the outer side wall of the corresponding sliding tube 71 or the outer side wall of the corresponding piston plate 21. Guiding long holes 52 are formed in both the telescopic sleeve 12 and the extension sleeve 7. The guiding member 51 on the outer side wall of the sliding tube 71 is inserted and matched with the guiding long hole 52 on the adjacent extension sleeve 7 or the guiding long hole 52 on the adjacent telescopic sleeve 12, and the guiding member 51 on the piston plate 21 is inserted and matched with the guiding long hole 52 on the adjacent extension sleeve 7, and each guiding member 51 is slidably connected to the inner side wall of the corresponding guiding long hole 52 in the vertical direction.

[0072] This enables that when the piston plate 21 slides in the extension sleeve 7, the corresponding guiding member 51 and the guiding long hole 52 can cooperate to guide the movement of the piston plate 21; similarly, when two adjacent extension sleeves 7 slide relative to each other, the corresponding guiding member 51 and the guiding long hole 52 can cooperate to guide the relative sliding between the two extension sleeves 7; similarly, when the extension sleeve 7 slides in the telescopic sleeve 12, the corresponding guiding member 51 and the guiding long hole 52 can cooperate to guide the sliding of the extension sleeve 7. This can improve the stability of the overall telescoping of the spotlight.

[0073] In this embodiment, refer to Figure 5 and Figure 6 , the guiding long holes 52 on the telescopic sleeve 12 have the same length as the guiding long holes 52 on the extension sleeve 7. The guiding long holes 52 on the extension sleeve 7 are formed on both the sliding tube 71 and the extension tube 72 at the same time. The guiding long holes 52 on the telescopic sleeve 12 are staggered from the guiding long holes 52 on the adjacent extension sleeve 7, and the guiding long holes 52 on two adjacent extension sleeves 7 are staggered from each other. This ensures that the formation of the guiding long holes 52 on the extension sleeve 7 does not affect the setting of its own guiding member 51.

[0074] Refer toFigure 8 and Figure 9 A multi-stage adjustment component 8 is arranged on the lower side of the lower limit ring 42, and the multi-stage adjustment component 8 includes a mounting ring 81, and the mounting ring 81 is detachably connected to the lower side wall of the interference ring 421, and the mounting ring 81 is coaxially arranged with the interference ring 421, and a plurality of extension sleeves 7 are all located in the mounting ring 81, and the outer side wall of the outermost extension sleeve 7 is slidably connected or spaced apart with the inner side wall of the mounting ring 81.

[0075] Reference Figure 8 and Figure 9 A support block 82 is disposed at the lower side of the mounting ring 81. The length direction of the support block 82 is disposed along the radial direction corresponding to the mounting ring 81, and the support block 82 is slidably connected to the inner wall of the mounting ring 81 along its own length direction. The lower ends of the plurality of extension sleeves 7 are disposed opposite to the support block 82. Moreover, when the spotlight is in use, the lower ends of the plurality of extension sleeves 7 abut against the support block 82, which can limit the use of the extension sleeves 7. At the same time, since the support block 82 can slide, the support block 82 can release the restriction on the extension sleeves 7, so that the user can select the number of layers of the extension sleeves 7 to be used according to actual needs.

[0076] Reference Figure 8 and Figure 10 A prompt component 9 is arranged between the support block 82 and the mounting ring 81. The prompt component 9 includes a marble 91 and a spring 92. A clearance hole 93 is provided on the upper side of the support block 82. Both the marble 91 and the spring 92 are arranged in the clearance hole 93. The marble 91 is slidably connected to the inner wall of the clearance hole 93 along the vertical direction. The spring 92 is located below the marble 91. The upper end of the spring 92 is connected to the marble 91, and the lower end of the spring 92 is connected to the inner wall of the clearance hole 93. A plurality of prompt grooves 94 are provided on the mounting ring 81. The plurality of prompt grooves 94 are arranged in sequence along the length direction of the support block 82. During the sliding process of the support block 82, the plurality of clearance holes 93 are connected to the plurality of prompt grooves 94 in sequence. When the prompt grooves 94 are connected to the clearance holes 93, the spring 92 resists the marble 91 and is inserted into the corresponding prompt grooves 94.

[0077] In this embodiment, refer to Figure 10 The inner wall of the prompt groove 94 is an arc-shaped surface, and the inner wall of the prompt groove 94 fits with the outer wall of the marble 91, which makes it easy for the marble 91 to be inserted into the corresponding prompt groove 94 and also easy for the marble 91 to be pushed out of the corresponding prompt groove 94.

[0078] In this embodiment, refer to Figure 9 and Figure 10 The number of the prompt grooves 94 is the same as the number of the extension sleeves 7, and the prompt grooves 94 are arranged one-to-one with the extension sleeves 7. During the sliding process of the support block 82, when the marble 91 is stuck in the corresponding prompt groove 94, the support block 82 releases the limit of the corresponding extension sleeve 7.

[0079] When the user selects the number of layers of extension sleeves 7 to be used, the support block 82 slides on the mounting ring 81, and during this process, every time the marble 91 is inserted into a different prompt groove 94, the spring 92 resists the marble 91 and hits the inner wall of the corresponding prompt groove 94, thereby making a crisp clicking sound, which makes it easy for the user to know the adjusted length of the support block 82 and the number of extension sleeves 7 that have been released from the restriction.

[0080] In this embodiment, refer to Figure 8 There are a plurality of support blocks 82, and the plurality of support blocks 82 are sequentially spaced apart along the circumference of the mounting ring 81. The cooperation of the plurality of support blocks 82 can improve the stability of the support of the plurality of layers of the extension sleeves 7.

[0081] Reference Figure 8 The prompting assembly 9 also includes an indicator pointer 95, which is disposed on the lower side of the support block 82, and the length direction of the indicator pointer 95 is disposed along the width direction of the support block 82. A plurality of indicator scales 96 are disposed on the lower side wall of the mounting ring 81, and the plurality of indicator scales 96 are disposed on one side of the width direction of the support block 82, and the plurality of indicator scales 96 are disposed in sequence and at intervals along the length direction of the support block 82. During the sliding process of the support block 82, the indicator pointer 95 passes through all the indicator scales 96 in sequence.

[0082] In this embodiment, the number of indicating scales 96 is the same as the number of extension sleeves 7, and the indicating scales 96 and the extension sleeves 7 are arranged one by one. During the sliding process of the support block 82, when the indicating pointer 95 points to the corresponding indicating scale 96, the support block 82 releases the limit of the corresponding extension sleeve 7.

[0083] Based on the setting of the indicator pointer 95 and the indicator scale 96, it is convenient for the user to determine the number of extended sleeves 7 that have been released from restriction by visual inspection.

[0084] The implementation principle of the embodiment of the present application is: the spotlight is embedded in the ceiling, and then the spotlight body 3 is pulled out from the telescopic sleeve 12, and the spotlight can adjust the irradiation angle. However, during the process of adjusting the irradiation angle, when the height of the spotlight body 3 still cannot meet the corresponding requirements, slide a number of support blocks 82 to release the limit of the innermost extension sleeve 7, and the spotlight body 3 can adjust the position in the vertical direction and adjust the irradiation angle at the same time. If the height of the spotlight body 3 still does not meet the corresponding requirements, slide a number of support blocks 82 to release the limit of another layer of extension sleeve 7, and the adjustable distance of the spotlight body 3 in the vertical direction is further increased. Similarly, by sequentially releasing the limit of all extension sleeves 7 by the support blocks 82, the adjustable range of the spotlight body 3 in the vertical direction can be continuously increased.

[0085] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Identical components are denoted by identical reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
