Description

Technical Field

[0001] The present disclosure relates to the technical field of projection lamps, and particularly to a mounting device and a projection lamp. Background Art

[0002] A projection lamp is an advanced lighting device that can project light onto different planes such as walls and floors to obtain different lighting effects and visual experiences. It is mostly used in public places such as commercial or entertainment venues to project advertisements or promotional information.

[0003] Currently, when replacing the image content of projection lamp products on the market, the entire projection lamp product must be disassembled and reinstalled to replace the internal lens. For example, in the lighting projection device with the patent publication number CN114283713B, when replacing the projection content, the user needs to first disassemble the lamp body, then replace the lens, and then reassemble the lamp body, making the lens replacement steps cumbersome, resulting in a low lens replacement efficiency and a poor user experience of the projection lamp. Utility Model Content

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a mounting device and a projection lamp that can quickly replace the lens.

[0005] The purpose of the present disclosure is achieved through the following technical solutions:

[0006] A mounting device for mounting a lens, characterized in that the mounting device includes:

[0007] A housing having a sliding cavity and a receiving groove, the sliding cavity communicating with the receiving groove, the receiving groove being for movably receiving the lens;

[0008] An inner cylinder located in the sliding cavity and slidably connected to the housing, a fixed cavity and a light outlet being formed in the inner cylinder and communicating with each other;

[0009] A light emitting mechanism disposed in the fixed cavity, the light emitting end of the light emitting mechanism facing the receiving groove through the light outlet;

[0010] A limiting mechanism, the limiting mechanism being connected to one of the inner wall of the housing and the inner cylinder, the limiting mechanism being for engaging or disengaging from the outer wall of the lens;

[0011] A locking spring mechanism for locking or releasing the inner cylinder to the housing;

[0012] When the lens is mounted in the receiving groove, the locking spring mechanism locks the inner cylinder to the housing, and at this time the limiting mechanism engages with the outer wall of the lens;

[0013] When the lens is removed from the accommodation groove, the locking spring mechanism releases the inner cylinder to the outer shell, and at this time, the limiting mechanism separates from the outer wall of the lens.

[0014] A projection lamp includes a lens and the mounting device described in any one of the above embodiments.

[0015] Compared with the prior art, the present disclosure has at least the following advantages:

[0016] 1. When the lens is installed in the accommodation groove, the locking spring mechanism locks the inner cylinder to the outer shell. At this time, the limiting mechanism engages with the outer wall of the lens to fix the lens in the accommodation groove. When the lens is removed from the accommodation groove, the locking spring mechanism releases the inner cylinder to the outer shell. At this time, the limiting mechanism separates from the outer wall of the lens, allowing the lens to be disengaged from the accommodation groove. In this way, there is no need to disassemble the mounting device during the process of replacing the lens, that is, there is no need to disassemble the mounting device when disassembling or installing the lens, greatly improving the disassembly, installation and replacement efficiency of the lens and achieving the effect of quick lens replacement.

[0017] 2. Since the light-emitting end of the light-emitting mechanism faces the accommodation groove through the light-emitting port, and the accommodation groove movably accommodates the lens. When the lens is installed in the accommodation groove, the light emitted by the light-emitting end of the light-emitting mechanism can be projected through the lens in the accommodation groove. Also, due to the greatly improved disassembly, installation and replacement efficiency of the lens, the convenience of using the projection lamp is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To better understand the technical solutions and beneficial effects of this disclosure, the following further details this disclosure with specific embodiments:

[0038] Please refer to Figures 1 to 13 , which shows that the projection lamp 20 of an embodiment of the present utility model includes a lens 21 and a mounting device 10, and the lens 21 is mounted on the mounting device 10. Further, the mounting device 10 includes a housing 100, an inner cylinder 200, a light emitting mechanism 300, a limiting mechanism 400, and a locking spring mechanism 500. The housing 100 is provided with a sliding cavity 121 and a receiving groove 122, and the sliding cavity 121 communicates with the receiving groove 122. The receiving groove 122 is used for movably receiving the lens 21, that is, the lens 21 is disassembled and assembled through the receiving groove 122.

[0039] As Figure 2 shown, the inner cylinder 200 is located in the sliding cavity 121 and is slidably connected to the housing 100. A fixed cavity 210 and a light outlet 220 that communicate with each other are formed in the inner cylinder 200. The light emitting mechanism 300 is disposed in the fixed cavity 210, and the light emitting end of the light emitting mechanism 300 faces the receiving groove 122 through the light outlet 220. The limiting mechanism 400 is connected to one of the housing 100 and the inner cylinder 200, that is, the limiting mechanism 400 is connected to the housing 100 or the inner cylinder 200. The limiting mechanism 400 is used for engaging or separating from the outer wall of the lens 21. The locking spring mechanism 500 is used for locking or releasing the inner cylinder 200 to / from the housing 100.

[0040] When the lens 21 is installed in the receiving groove 122, the locking spring mechanism 500 locks the inner cylinder 200 to the housing 100 and drives the limiting mechanism 400 to engage with the outer wall of the lens 21, so that the lens 21 is fixed in the receiving groove 122, completing the installation of the lens 21;

[0041] When the lens 21 is disassembled from the receiving groove 122, the locking spring mechanism 500 releases the inner cylinder 200 from the housing 100 and drives the limiting mechanism 400 to separate from the outer wall of the lens 21, so that the lens 21 is disengaged from the receiving groove 122, completing the disassembly of the lens 21.

[0042] The above-mentioned projection lamp 20 and its mounting device 10. When the lens 21 is installed in the accommodation groove 122, the locking spring mechanism 500 locks the inner cylinder 200 to the outer shell 100. At this time, the limiting mechanism 400 engages with the outer wall of the lens 21, fixing the lens 21 in the accommodation groove 122; when the lens 21 is removed from the accommodation groove 122, the locking spring mechanism 500 releases the inner cylinder 200 from the outer shell 100. At this time, the limiting mechanism 400 separates from the outer wall of the lens 21, allowing the lens 21 to disengage from the accommodation groove 122; thus, during the process of replacing the lens 21, there is no need to disassemble the mounting device 10, that is, there is no need to disassemble the mounting device during the process of disassembling or installing the lens 21, greatly improving the disassembly, installation and replacement efficiency of the lens 21, and achieving the effect of quick replacement of the lens 21; since the light-emitting end of the light-emitting mechanism 300 is arranged towards the accommodation groove 122 through the light-emitting port 220, and the accommodation groove 122 movably accommodates the lens 21. When the lens 21 is installed in the accommodation groove 122, the light emitted by the light-emitting end of the light-emitting mechanism 300 can be projected through the lens 21 in the accommodation groove 122. Also, because the disassembly, installation and replacement efficiency of the lens 21 is greatly improved, the convenience of using the projection lamp 20 is enhanced.

[0043] The above-mentioned projection lamp 20 can achieve different lighting projection effects by replacing different lenses 21; the quick and convenient replacement of the lens 21 is realized through the above-mentioned mounting device 10, without the need to rely on additional tools, nor to disassemble the mounting device 10, reducing the procedures for replacing different lenses 21 of the projection lamp 20, and at the same time improving the replacement efficiency of the lens 21.

[0044] In one embodiment, the outer shell 100 is further provided with a through groove 123. The sliding cavity 121 is respectively communicated with the accommodation groove 122 and the through groove 123. The locking spring mechanism 500 is respectively connected to the outer shell 100 and the inner cylinder 200 through the through groove 123, enabling the locking spring mechanism 500 to be reliably connected to the outer shell 100 and the inner cylinder 200 respectively, and at the same time making the structure of the mounting device 10 more compact. In this embodiment, the through groove 123 is opened on the outer peripheral side of the outer shell 100, and the number of the through grooves 123 is two. The two through grooves 123 are opened on the opposite side walls of the outer shell 100.

[0045] As Figures 2 to 7 shown, in one of the embodiments, the inner cylinder 200 is also slidably connected in the through groove 123. The through groove 123 has a limiting effect on the inner cylinder 200, avoiding the situation where the inner cylinder 200 rotates during the sliding process relative to the outer shell 100, and at the same time reducing the swing or vibration during the sliding process of the inner cylinder 200, making the sliding of the inner cylinder 200 relative to the outer shell 100 more stable, and at the same time facilitating the installation of the locking spring mechanism 500, improving the assembly convenience of the mounting device 10.

[0046] As Figure 1 、 Figure 6 and Figure 7As shown, in one embodiment, the housing 100 includes a housing body 120 and a top cover 110. A sliding cavity 121, a through slot 123, and a receiving slot 122 are all formed in the housing body 120. The top cover 110 is disposed within the sliding cavity 121 of the housing body 120, reducing the manufacturing difficulty of the housing 100. In this embodiment, the housing body 120 is vertically installed and placed, the top cover 110 is located on the top side of the housing body 120, the sliding cavity 121 is formed on the top side of the housing body 120, and the receiving slot 122 is formed on the bottom side of the housing body 120.

[0047] As Figure 1 , Figure 6 and Figure 7 shown, further, a plurality of snap fasteners 1101 are formed on the periphery of the top cover 110 and are circumferentially and spaced apart from each other. A plurality of card slots 1201 are formed in the housing body 120. The plurality of card slots 1201 are respectively and correspondingly clamped with the plurality of snap fasteners 1101, avoiding the relative loosening of the top cover 110 and the housing body 120, enabling the reliable fixation of the housing body 120 and the top cover 110, and simultaneously realizing the rapid assembly and fixation of the housing body 120 and the top cover 110.

[0048] As Figure 1 , Figure 6 and Figure 7 shown, further, a plurality of avoidance slots 201 are formed on the periphery of the inner cylinder 200. The plurality of avoidance slots 201 are respectively and correspondingly arranged with the plurality of snap fasteners 1101. The plurality of snap fasteners 1101 are clamped in the corresponding card slots 1201 through the corresponding avoidance slots 201. In this way, the reliable snap connection between the housing body 120 and the top cover 110 is achieved, and at the same time, the interference of the inner cylinder 200 during sliding in the sliding cavity 121 is avoided, making the structure of the mounting device 10 relatively compact.

[0049] As Figure 1 , Figure 2 , Figure 14 and Figure 15 shown, the locking spring mechanism 500 includes an elastic component 510 and a locking component 520. The locking component 520 is respectively connected to the housing 100 and the inner cylinder 200. Two ends of the elastic component 510 are respectively connected to the housing 100 and the inner cylinder 200.

[0050] When the lens 21 is installed in the receiving slot 122, the locking component 520 locks the inner cylinder 200 to the housing 100, and the elastic component 510 is in an elastically compressed or stretched state.

[0051] When the lens 21 is removed from the receiving slot 122, the locking component 520 releases from the housing 100, and the elastic component 510 automatically resets.

[0052] As Figure 1 and Figure 2As shown, in this embodiment, the locking assembly 520 is respectively connected to the outer shell 100 and the inner cylinder 200 through the through slots 123, that is, the locking assembly 520 is respectively connected to the top cover 110 and the inner cylinder 200 through the through slots 123. The two ends of the elastic assembly 510 are respectively connected to the outer shell 100 and the inner cylinder 200.

[0053] As Figure 2 or Figure 4 shown, when the lens 21 is installed in the accommodation slot 122, that is, when the locking assembly 520 is in the locked state, the locking assembly 520 locks the inner cylinder 200 to the outer shell 100, that is, the inner cylinder 200 is relatively stationary with respect to the outer shell 100, and the elastic assembly 510 is in an elastically compressed state or an elastically stretched state, realizing the caching of the elastic potential energy of the elastic assembly 510. At this time, the limiting mechanism 400 is engaged with the outer wall of the lens 21;

[0054] When the lens 21 is removed from the accommodation slot 122, the locking assembly 520 is released from the outer shell 100, that is, when the locking assembly 520 is in the unlocked state, the elastic assembly 510 automatically resets, realizing the release of the elastic potential energy of the elastic assembly 510, so that the elastic assembly 510 drives the inner cylinder 200 to slide relative to the outer shell 100. At this time, the limiting mechanism 400 is separated from the outer wall of the lens 21.

[0055] In this embodiment, when the lens 21 is installed in the accommodation slot 122, the elastic assembly 510 is in an elastically compressed state. In other embodiments, the elastic assembly 510 is not limited to being in an elastically compressed state. As Figure 4 shown, it can also be in an elastically stretched state.

[0056] In this embodiment, the locking and elastic mechanism 500 is a pressing and switching locking and elastic mechanism, that is, by manually applying a force directly or indirectly to the inner cylinder 200, such as a pressing force, to make the inner cylinder 200 slide relative to the outer shell 100, that is, to change the relative sliding position of the inner cylinder 200 relative to the outer shell 100, realizing the reciprocating switching between the locked state and the unlocked state of the locking assembly 520. For example, by mechanically pressing the lens through the accommodation slot 122, the lens is pushed to act on the inner cylinder 200 indirectly, so that the inner cylinder 200 slides relative to the outer shell 100, realizing the reciprocating switching of the locking assembly 520 between the locked state and the unlocked state, and realizing the quick disassembly and assembly of the lens 21.

[0057] Specifically, when the lens 21 is pushed upward through the accommodation slot 122 by a predetermined distance and then released, at this time, the lens 21 drives the inner cylinder 200 to slide relative to the outer shell 100 in the first direction to the first predetermined position, and the locking assembly 520 switches from the unlocked state to the locked state, locking the inner cylinder 200 to the outer shell 100, and the elastic assembly 510 is in an elastically compressed or stretched state;

[0058] When the lens 21 is pushed upward through the receiving groove 122 and slides a predetermined distance and then released, the lens 21 drives the inner cylinder 200 to slide relative to the outer shell 100 in the second direction to a second predetermined position, the locking assembly 520 switches from the locked state to the unlocked state, the inner cylinder 200 is released from the outer shell 100, and the elastic assembly 510 automatically resets.

[0059] As Figure 14 and Figure 15 shown, in other embodiments, the through groove 123 can be omitted, the locking and elastic mechanism 500 is located inside the outer shell 100, and the locking and elastic mechanism 500 is respectively connected to the outer shell 100 and the inner cylinder 200. When the lens 21 is installed in the receiving groove 122, the locking assembly 520 is in the locked state, the locking assembly 520 locks the inner cylinder 200 to the outer shell 100, and the elastic assembly 510 is in the elastic compression state or the elastic tension state. At this time, the limiting mechanism 400 is engaged with the outer wall of the lens 21. When the lens 21 is removed from the receiving groove 122, the locking assembly 520 is released from the outer shell 100, and the elastic assembly 510 automatically resets, so that the elastic assembly 510 drives the inner cylinder 200 to slide relative to the outer shell 100. At this time, the limiting mechanism 400 is separated from the outer wall of the lens 21. The locking and elastic mechanism 500 is located inside the outer shell 100, making the structure of the mounting device 10 more compact. At the same time, the locking and elastic mechanism 500 is not easily interfered with or damaged by external objects, thereby improving the stability of the mounting device 10.

[0060] As Figure 2 shown, in one of the embodiments, the elastic assembly 510 is located in the sliding cavity 121; when the lens 21 is installed in the receiving groove 122, the assembly 510 is in the elastic compression state. Further, both ends of the elastic assembly 510 are respectively connected to the top cover 110 and the inner wall of the inner cylinder 200. When the inner cylinder 200 slides upward relative to the outer shell 100 to the first predetermined position, the locking assembly 520 locks the inner cylinder 200 inside the outer shell 100, and the elastic assembly 510 is in the compressed state; when the inner cylinder 200 slides downward relative to the outer shell 100 to the second predetermined position, the locking assembly 520 is unlocked to release the inner cylinder 200, the inner cylinder 200 is released from the outer shell 100, and the elastic assembly 510 resets. The elastic assembly 510 is located in the sliding cavity 121, making the structure of the mounting device 10 more compact. At the same time, the elastic assembly 510 is not easily interfered with or damaged by external objects, thereby improving the stability and service life of the mounting device 10. In this embodiment, both ends of the elastic assembly 510 are respectively welded to the top cover 110 and the inner wall of the inner cylinder 200.

[0061] It can be understood that in other embodiments, the elastic assembly 510 is not limited to being located in the sliding cavity 121. For example, as Figure 4As shown, in one embodiment, the elastic component 510 is located outside the inner cylinder 200, and both ends of the elastic component 510 are respectively connected to the outer wall of the inner cylinder 200 and the outer peripheral wall of the outer shell 100. When the lens 21 is installed in the accommodation groove 122, the elastic component 510 is in an elastically stretched state. Further, the inner cylinder 200 is formed with a first fixing boss 230, and the outer shell 100 is formed with a second fixing boss 240. The second fixing boss 240 is located below the first fixing boss 230, and both ends of the elastic component 510 are respectively connected to the first fixing boss 230 and the second fixing boss 240. When the inner cylinder 200 slides upward relative to the outer shell 100 to a first predetermined position, the locking component 520 locks the inner cylinder 200 to the outer shell 100, and the elastic component 510 is in a stretched state; when the inner cylinder 200 slides downward relative to the outer shell 100 to a second predetermined position, the locking component 520 is unlocked to release the inner cylinder 200, that is, the inner cylinder 200 is released from the outer shell 100, and the elastic component 510 is reset.

[0062] In this embodiment, the first fixing boss 230 extends out of the outer shell 100 through the through groove 123. Specifically, the number of the through groove 123, the first fixing boss 230, the second fixing boss 240, and the elastic component 510 is two. The two first fixing bosses 230 respectively pass through the corresponding through grooves 123, and the two second fixing bosses 240 are located below the corresponding first fixing bosses 230. Both ends of each elastic component 510 are respectively connected to the corresponding first fixing boss 230 and the corresponding second fixing boss 240. It can be understood that the through groove 123 limits the movement range of the inner cylinder 200 sliding relative to the outer shell 100 by limiting the first fixing boss 230. At the same time, the elastic component 510 is arranged outside the installation device 10, which is convenient for replacement and maintenance.

[0063] As Figure 2 、 Figure 8 and Figure 10As shown, in one embodiment, the locking assembly 520 includes a locking block 521 and a locking pull rod 522. The locking block 521 is provided on one of the inner cylinder 200 and the top cover 110. The locking block 521 is provided with a labyrinth channel 523. One end of the locking pull rod 522 is rotatably provided on the other of the inner cylinder 200 and the top cover 110. The other end of the locking pull rod 522 slides in the labyrinth channel 523. The end of the inner cylinder 200 adjacent to the accommodating groove 122 after sliding relative to the outer shell 100 is taken as the reference end. In this embodiment, when the locking assembly 520 locks the inner cylinder 200 to the outer shell 100 through the through groove 123, the locking pull rod 522 is located at a position adjacent to the reference end of the locking block 521. When the locking assembly 520 releases the inner cylinder 200 from the outer shell 100 through the through groove 123, the locking pull rod 522 is located at a position away from the reference end of the locking block 521. Thus, by sliding the inner cylinder 200 relative to the outer shell 100, the relative sliding position of the locking pull rod 522 in the labyrinth channel 523 is changed, realizing the switching between the unlocked state and the locked state of the locking assembly 520.

[0064] Specifically, when the lens 21 is pushed through the accommodating groove 122 and the lens 21 drives the inner cylinder 200 to slide relative to the outer shell 100 to a first predetermined position, the locking assembly 520 switches from the unlocked state to the locked state. The locking pull rod 522 moves in the labyrinth channel 523 from a position away from the reference end of the locking block 521 to a position adjacent to the reference end of the locking block 521, locking the inner cylinder 200 in the outer shell 100, and the elastic assembly 510 is in an elastically compressed or stretched state;

[0065] When the lens 21 is pushed through the accommodating groove 122 and the lens 21 drives the inner cylinder 200 to slide relative to the outer shell 100 to a second predetermined position, the locking assembly 520 switches from the locked state to the unlocked state. The locking pull rod 522 moves in the labyrinth channel 523 from a position adjacent to the reference end of the locking block 521 to a position away from the reference end of the locking block 521, releasing the inner cylinder 200 from the outer shell 100, and the elastic assembly 510 automatically resets.

[0066] It can be understood that, such as Figure 14 and Figure 15As shown, in other embodiments, the through slot 123 may be omitted, and the locking spring mechanism 500 is disposed within the outer housing 100. The locking spring mechanism 500 is respectively connected to the outer housing 100 and the inner cylinder 200. When the locking assembly 520 locks the inner cylinder 200 to the outer housing 100, the locking pull rod 522 is located at a position adjacent to the reference end of the locking block 521. When the locking assembly 520 releases the inner cylinder 200 from the outer housing 100, the locking pull rod 522 is located at a position away from the reference end of the locking block 521. Thus, by sliding the inner cylinder 200 relative to the outer housing 100, the relative sliding position of the locking pull rod 522 within the labyrinth channel 523 is changed, realizing the switching between the unlocked state and the locked state of the locking assembly 520.

[0067] As Figure 2 shown, in one of the embodiments, the locking block 521 is disposed on the inner cylinder 200, and one end of the locking pull rod 522 is rotatably arranged on the top cover 110. In this embodiment, the locking pull rod 522 is rotatably connected to the top cover 110, and the end of the locking pull rod 522 rotatably connected to the top cover 110 is located outside the housing 120, which can improve the stability and reliability of the reciprocating switching of the locking pull rod 522 between the locked state and the unlocked state. In other embodiments, the end of the locking pull rod 522 rotatably connected to the top cover 110 is not limited to the outside of the housing 120. For example, as Figure 14 and Figure 15 shown, the end of the locking pull rod 522 rotatably connected to the top cover 110 is located inside the inner cylinder 200.

[0068] It can be understood that in other embodiments, the rotational arrangement positions of the locking block 521 and the locking pull rod 522 can be interchanged. For example, the locking block 521 is disposed on the top cover, and one end of the locking pull rod 522 is rotatably arranged on the inner cylinder 200.

[0069] As Figures 11 to 13As shown, in one of the embodiments, the locking block 521 is convexly provided with a stop block 524, and the labyrinth channel 523 is arranged around the stop block 524; the labyrinth channel 523 includes an inclined line guiding groove 5231, a straight line guiding groove 5232 and a high and low stop groove 5233. The inclined line guiding groove 5231 is communicated with the straight line guiding groove 5232 through the high and low stop groove 5233. The stop portion 5241 of the stop block 524 is correspondingly arranged at the middle position of the high and low stop groove 5233, and the groove depth of the inclined line guiding groove 5231 is greater than the groove depth of the straight line guiding groove 5232. When the locking pull rod 522 slides from the inclined line guiding groove 5231 to the middle position of the high and low stop groove 5233, the locking pull rod 522 slides in the high and low stop groove 5233 until it abuts against the stop portion 5241, so that the locking pull rod 522 moves from a position far from the reference end of the locking block 521 to a position adjacent to the reference end of the locking block 521 in the labyrinth channel 523, and the locking assembly 520 is switched from the unlocked state to the locked state; when the locking pull rod 522 slides from the middle position of the high and low stop groove 5233 to the straight line guiding groove 5232 until the locking pull rod 522 slides into the inclined line guiding groove 5231 through the straight line guiding groove 5232, the locking pull rod 522 moves from a position adjacent to the reference end of the locking block 521 to a position far from the reference end of the locking block 521 in the labyrinth channel 523, and the locking assembly 520 is switched from the locked state to the unlocked state.

[0070] In this embodiment, the part where the inclined line guiding groove 5231 is communicated with the straight line guiding groove 5232 is the first part, and the part where the inclined line guiding groove 5231 is communicated with the high and low stop groove 5233 is the second part; the part where the high and low stop groove 5233 is communicated with the second part is the third part, the part where the high and low stop groove 5233 is communicated with the straight line guiding groove 5232 is the fourth part, the part where the straight line guiding groove 5232 is communicated with the fourth part is the fifth part, and the part where the straight line guiding groove 5232 is communicated with the first part is the sixth part.

[0071] When the locking pull rod 522 slides from the first part, the second part and the third part to the middle position of the high and low stop groove 5233 in sequence, the locking pull rod 522 moves from a position far from the reference end of the locking block 521 to a position adjacent to the reference end of the locking block 521 in the labyrinth channel 523, and the locking assembly 520 is switched from the unlocked state to the locked state; when the locking pull rod 522 slides from the middle position of the high and low stop groove 5233, the fourth part and the fifth part to the sixth part in sequence, the locking pull rod 522 moves from a position adjacent to the reference end of the locking block 521 to a position far from the reference end of the locking block 521 in the labyrinth channel 523, and the locking assembly 520 is switched from the locked state to the unlocked state.

[0072] Such as Figure 12 and Figure 13As shown, further, the groove depth of the diagonal guide groove 5231 gradually increases from the first part to the second part; the groove depth of the high-low stop groove 5233 first decreases and then increases from the third part to the middle position of the high-low stop groove 5233, so that a second step 523b is formed at the position where the middle position of the high-low stop groove 5233 communicates with the third part.

[0073] As Figure 12 and Figure 13 As shown, further, the groove depth of the third part is greater than that of the second part, so that a first step 523a is formed between the high-low stop groove 5233 and the diagonal guide groove 5231, that is, a step difference is formed between the high-low stop groove 5233 and the diagonal guide groove 5231, preventing the locking pull rod 522 that slides into the high-low stop groove 5233 from sliding back into the diagonal guide groove 5231; thus, when the locking pull rod 522 slides from the first part, the second part and the third part to the middle position of the high-low stop groove 5233 in sequence, the locking pull rod 522 can move reliably from the position far away from the reference end of the locking block 521 to the position adjacent to the reference end of the locking block 521 in the labyrinth groove 523.

[0074] As Figure 12 and Figure 13 As shown, further, the groove depth of the high-low stop groove 5233 gradually decreases from the middle position of the high-low stop groove 5233 to the fourth part, and a third step 523c is formed at the connection between the middle position of the high-low stop groove 5233 and the fourth part. Since the groove depth of the high-low stop groove 5233 first decreases and then increases from the third part to the middle position of the high-low stop groove 5233, a deeper groove position is formed at the middle position of the high-low stop groove 5233, preventing the locking pull rod 522 from easily disengaging from the stop part 5241.

[0075] The path from the third part to the middle position of the high-low stop groove 5233 is the locking path, and the path from the middle position of the high-low stop groove 5233 to the fourth part is the unlocking path. There is a preset angle between the locking path and the unlocking path, and there is an angle between the unlocking path and the extending path of the linear guide groove 5232. The extending direction of the extending path of the linear guide groove 5232 is parallel to the sliding direction of the inner cylinder 200 relative to the outer shell 100. Thus, when the locking pull rod slides along the unlocking path to the fifth part, it can only slide along the extending path of the linear guide groove 5232 to achieve reliable unlocking. The groove depth of the sixth part is less than that of the first part, so that there is a fourth step 523d between the sixth part and the first part, preventing the locking pull rod 522 from retracting from the first part to the sixth part. When the locking pull rod 522 slides from the middle position, the fourth part, and the fifth part of the high-low stop groove 5233 to the sixth part in sequence, the locking pull rod 522 reliably moves from the position adjacent to the reference end of the locking block 521 to the position away from the reference end of the locking block 521 within the labyrinth groove 523. Thus, the locking pull rod 522 can only slide along the predetermined circumferential sliding direction within the labyrinth groove 523.

[0076] In this embodiment, the special structure of the locking block 521 is used to guide the movement or stillness of the locking pull rod 522 to change the positional relationship and connection relationship between the inner cylinder 200 and the top cover 110, realizing the reciprocating switching between the locked state and the unlocked state of the locking assembly 520. When the lens 21 is installed in the accommodating groove 122, the locking spring mechanism 500 locks the inner cylinder 200 to the outer shell 100. At this time, the limiting mechanism 400 is engaged with the outer wall of the lens 21 to fix the lens 21 in the accommodating groove 122; when the lens 21 is removed from the accommodating groove 122, the locking spring mechanism 500 releases the inner cylinder 200 from the outer shell 100. At this time, the limiting mechanism 400 is separated from the outer wall of the lens 21. When reciprocatingly switching between the locked state and the unlocked state of the locking assembly 520, the limiting mechanism 400 reciprocatingly switches between two states of being engaged with or separated from the outer wall of the lens 21, thereby improving the convenience of the disassembly and assembly operations of the lens 21.

[0077] As Figure 12 and Figure 13 shown, further, the groove depth of the linear guide groove 5232 first decreases and then remains constant from the fifth part to the sixth part, so that the bottom wall of the linear guide groove 5232 forms a first increasing inclined surface 5232a. Further still, the groove depth of the inclined guide groove 5231 first decreases and then remains constant from the first part to the second part, so that the bottom wall of the inclined guide groove 5231 forms a second increasing inclined surface 5231a.

[0078] It can be understood that in other embodiments, the locking and ejecting mechanism 500 is not limited to a pressing and ejecting mechanism. For example, the locking and ejecting mechanism 500 can also be an electromagnetic ejecting mechanism, that is, the locking component 520 is an electromagnetic component, and a magnetic field force is generated by energizing the locking component 520 and acts on the inner cylinder 200; when the locking component 520 is energized and the magnetic field force of the locking component 520 is greater than the elastic force of the elastic component 510, the inner cylinder 200 is locked to the outer shell 100; when the locking component 520 is de-energized and the magnetic field force of the locking component 520 is less than the elastic force of the elastic component 510, the inner cylinder 200 is released from the outer shell 100.

[0079] As Figure 2 shown, in one of the embodiments, the limiting mechanism 400 is a clamping mechanism. The limiting mechanism 400 is connected to the inner cylinder 200 and is used to clamp or separate from the outer wall of the lens 21, so that the limiting mechanism 400 can reliably fix the lens 21 when the lens 21 is installed in the receiving groove and can reliably separate from the lens 21 when the lens 21 is removed from the receiving groove 122.

[0080] As Figures 2 to 9 shown, in one of the embodiments, the limiting mechanism 400 is a mechanical separation and clamping mechanism 410. In this embodiment, the limiting mechanism 400 includes a buckle member 411. The buckle member 411 includes a connecting portion 4111 and a buckle portion 4112 connected in sequence. The connecting portion 4111 is connected to the inner cylinder 200, and the locking and ejecting mechanism 500 drives the buckle portion 4112 to clamp or separate from the outer wall of the lens 21 through the inner cylinder 200; when the lens 21 is installed in the receiving groove 122, the inner cylinder 200 slides relative to the outer shell 100 in the first direction, and the locking and ejecting mechanism 500 drives the buckle portion 4112 to clamp to the outer wall of the lens 21 through the inner cylinder 200 until the locking and ejecting mechanism 500 locks the inner cylinder 200 to the outer shell 100, so that the lens 21 is fixed in the receiving groove 122; when the lens 21 is removed from the receiving groove 122, the locking and ejecting mechanism 500 releases the inner cylinder 200 from the outer shell 100, and the inner cylinder 200 slides relative to the outer shell 100 in the second direction until the locking and ejecting mechanism 500 drives the buckle portion 4112 to separate from the outer wall of the lens 21 through the inner cylinder 200, so that the lens 21 is detached from the receiving groove 122; the first direction is opposite to the second direction.

[0081] In this way, by the relative sliding of the inner cylinder 200 and the outer shell 100, the state switching of the snap portion 4112 being engaged or disengaged from the outer wall of the lens 21 is achieved. In this embodiment, due to the sliding action of the inner cylinder 200 relative to the outer shell 100, since the connecting portion 4111 is connected to the inner cylinder 200 and the snap portion 4112 is connected to the connecting portion 4111, the inner cylinder 200 drives the snap portion 4112 to act through the connecting portion 4111, so that the snap portion 4112 is engaged or disengaged from the outer wall of the lens 21. When the snap portion 4112 is engaged with the outer wall of the lens 21, that is, the snap portion 4112 abuts against the outer wall of the lens 21, the lens 21 is reliably mounted and fixed in the accommodation groove 122, and at this time, the lens 21 will not fall out of the accommodation groove 122; when the snap portion 4112 is disengaged from the outer wall of the lens 21, the lens 21 can be detached from the accommodation groove 122, that is, the snap portion 4112 is disengaged from the outer wall of the lens 21, so that the lens 21 can be quickly and reliably disassembled from the accommodation groove 122.

[0082] As Figure 2 or Figure 4 shown, in one embodiment, a limiting groove 22 is formed on the outer wall of the lens 21, and the limiting mechanism 400 is used to be engaged or disengaged from the limiting groove 22 on the outer wall of the lens 21. When the limiting mechanism 400 is engaged with the limiting groove 22 on the outer wall of the lens 21, the limiting mechanism 400 reliably mounts the lens 21 in the accommodation groove 122, avoiding the problem that the lens 21 falls out of the accommodation groove 122. Specifically, when the limiting mechanism 400 is a mechanical separation and engagement mechanism 410, the limiting groove 22 is adapted to the snap portion 4112, that is, the limiting groove 22 is a snap groove.

[0083] As Figure 2 、 Figure 6 、 Figure 8 and Figure 9 shown, further, the limiting mechanism 400 further includes a spreading member 412, a sliding portion 4113 is convexly provided on the side wall of the snap portion 4112, the spreading member 412 is fixed to the inner wall of the sliding cavity 121, and the sliding portion 4113 is slidably connected to the spreading member 412. When the inner cylinder 200 slides relative to the outer shell 100 in the first direction, the sliding portion 4113 slides relative to the spreading member 412 in the direction close to the light emitting mechanism 300, and the direction in which the sliding portion 4113 drives the snap portion 4112 to move is the positive direction, so that the locking spring mechanism 500 drives the snap portion 4112 to be engaged with the outer wall of the lens 21 through the inner cylinder 200; when the inner cylinder 200 slides relative to the outer shell 100 in the second direction, the sliding portion 4113 slides relative to the spreading member 412 in the direction away from the light emitting mechanism 300, and the direction in which the sliding portion 4113 drives the snap portion 4112 to move is the reverse direction, so that the locking spring mechanism 500 drives the snap portion 4112 to be disengaged from the outer wall of the lens 21 through the inner cylinder 200.

[0084] It can be understood that during the sliding of the sliding portion 4113 relative to the propping piece 412, the sliding portion 4113 drives the buckle portion 4112 to move away from or close to the lens 21, so that the buckle portion 4111 is engaged with or separated from the outer wall of the lens 21. In other words, the switching of the engaged or separated state of the buckle portion 4112 and the outer wall of the lens 21 is achieved by sliding and stretching the sliding portion 4113 relative to the propping piece 412.

[0085] In one embodiment, the process of disassembling and assembling the lens 21 to the mounting device 10 is as follows:

[0086] When installing the lens 21, the user pushes the lens 21 into the accommodating groove 122, so that the lens 21 abuts against the inner cylinder 200 and pushes the inner cylinder 200 to slide along the first direction relative to the outer shell 100, thereby driving the sliding portion 4113 of the buckle 411 to slide relative to the propping member 412 in the direction close to the light-emitting mechanism 300, and the sliding portion 4113 drives the buckle portion 412 to move in the positive direction until the inner cylinder 200 slides to the second predetermined position relative to the outer shell 100, so that the buckle portion 4112 of the limiting mechanism 400 is engaged with the outer wall of the lens 21, and at the same time, the inner cylinder 200 acts on the elastic component 510 to cause the elastic component 510 to produce elastic deformation, and the inner cylinder 200 is locked relative to the outer shell 100 through the locking component 520.

[0087] When removing the lens 21, the user pushes the inner cylinder 200 again, so that the locking assembly 520 releases the inner cylinder 200 relative to the outer shell 100, and at the same time the elastic assembly 510 resets and pushes the inner cylinder 200 to slide relative to the outer shell 100 along the second direction, so that the sliding portion 4113 slides relative to the propping member 412 in a direction away from the light-emitting mechanism 300, and the sliding portion 4113 drives the buckle portion 4112 to move in the opposite direction until the inner cylinder 200 slides to the first predetermined position relative to the outer shell 100, so that the buckle portion 4112 of the limiting mechanism 400 is separated from the outer wall of the lens 21, and the lens 21 is taken out at this time.

[0088] like Figure 2 , Figure 6 , Figure 8 and Figure 9 As shown, further, the direction in which the sliding portion 4113 slides relative to the opening member 412 is an oblique sliding opening direction, and there is a deformation angle between the direction in which the inner cylinder 200 slides relative to the outer shell 100 and the oblique sliding opening direction, so that the buckle portion 4112 can be reliably engaged with or separated from the outer wall of the lens 21. Furthermore, the deformation angle is 15° to 60°. In this embodiment, the deformation angle is 15°, so that the buckle portion 4112 can be reliably engaged with or separated from the outer wall of the lens 21, and at the same time, the resistance to the sliding of the sliding portion 4113 relative to the opening member 412 is small.

[0089] like Figure 2 ,Figure 6 , Figure 8 and Figure 9 As shown, further, the connecting portion 4111 is a deformable connecting portion. When the sliding portion 4113 slides relative to the propping member, the sliding portion 4113 drives the buckle portion 4112 to move away from or close to the lens 21. Since the connecting portion 4111 is a deformable connecting portion, the connecting portion 4111 can better adapt to the deformation caused by the change in the sliding position of the sliding portion 4113. When the locking and spring mechanism 500 drives the sliding portion 4113 to slide relative to the propping member 412 in the direction close to the light-emitting mechanism 300, the deformation of the connecting portion 4111 gradually decreases until it is reset. When the locking and spring mechanism 500 drives the sliding portion 4113 to slide relative to the propping member 412 in the direction away from the light-emitting mechanism 300, the deformation of the connecting portion 4111 gradually increases.

[0090] In one embodiment, the connecting portion 4111 is made of plastic or elastic rubber. Specifically, the connecting portion 4111 is made of plastic, and the inner cylinder 200, the connecting portion 4111, the buckle portion 4112 and the sliding portion 4113 are an integrated structure, so that the buckle portion 4112 is firmly connected to the inner cylinder 200 through the connecting portion 4111, and the structure of the installation device 10 is more compact.

[0091] It can be understood that in other embodiments, the inner cylinder 200, the connecting portion 4111, the buckle portion 4112 and the sliding portion 4113 are not limited to an integrally formed structure. To reduce the difficulty of forming, for example, the connecting portion 4111, the buckle portion 4112 and the sliding portion 4113 are an integrally formed structure, and the end of the connecting portion 4111 away from the buckle portion 4112 is glued to the end surface of the inner cylinder 200.

[0092] like Figure 2 , Figure 6 , Figure 8 and Figure 9As shown, in one embodiment, the end of the connecting portion 4111 away from the buckle portion 4112 is fixedly connected to the end surface of the inner cylinder 200 adjacent to the receiving groove 122, so that the connecting portion 4111 has a better deformation space, and the inner cylinder 200, the connecting portion 4111, the buckle portion 4112 and the sliding portion 4113 are better integrated. Further, the light outlet 220 is formed on the end surface of the inner cylinder 200 adjacent to the receiving groove 122, and the part where the connecting portion 4111 is fixedly connected to the inner cylinder 200 is staggered in the area where the light outlet 220 and the receiving groove 122 are opposite, so as to avoid the problem that the part where the connecting portion 4111 is fixedly connected to the inner cylinder 200 blocks the light output of the light emitting mechanism 300, so that the light emitting mechanism 300 can reliably emit light through the lens 21 in the receiving groove 122. Furthermore, an installation slot 202 connected to the light outlet 220 is provided on the end surface of the inner cylinder 200 adjacent to the accommodating groove 122, and the connecting portion 4111 is fixedly connected to the inner cylinder 200 through the installation slot 202, thereby better avoiding the problem of the connecting portion 4111 being fixedly connected to the inner cylinder 200 blocking the light output of the light-emitting mechanism 300.

[0093] It can be understood that in other embodiments, during the sliding process of the sliding portion 4113 relative to the propping member 412, the buckle portion 4112 is not limited to being engaged or separated from the outer wall of the lens 21 by the deformation of the connecting portion 4111. For example, the buckle portion 4112 is elastically rotatably connected to the connecting portion 4111. Specifically, the buckle portion 4112 is elastically rotatably connected to the connecting portion 4111 through a torsion spring (not shown). Further, the connecting portion 4111 is provided with a connecting hole (not shown), the buckle portion 4112 is provided with a rotating shaft (not shown), the rotating shaft sleeve is provided with a torsion spring, the rotating shaft is located in the connecting hole and is rotatably connected to the connecting portion 4111, one end of the torsion spring is fixed on the rotating shaft, and the other end of the torsion spring is fixed on the connecting portion 4111, so that the buckle portion 4112 is elastically rotatably connected to the connecting portion 4111 through the torsion spring. It should be noted that, during the sliding process of the sliding portion 4113 relative to the propping member 412 , the manners for achieving the engagement or separation of the buckle portion 4112 and the outer wall of the lens 21 include but are not limited to the above two methods.

[0094] like Figure 2 , Figure 6 , Figure 8 and Figure 9As shown, in one embodiment, the number of the fasteners 411 and the number of the opening members 412 are both two, and the connecting portions 4111 of the two fasteners 411 are respectively connected to the opposite side walls of the inner cylinder 200. The two fasteners 411 and the two opening members 412 are arranged one by one correspondingly, so that the fasteners 411 can be better engaged or separated from the opposite side walls of the lens 21. In this embodiment, the opposite sides of the lens 21 are provided with limiting grooves 22, and the fastener portions 4112 of the two fasteners 411 are used to engage or release the limiting grooves 22 of the opposite side walls of the lens 21. It should be noted that the number of the fasteners 411 is not limited to two, and can also be one or three or other numbers. The number of the opening members 412 is set according to the number of the fasteners 411, and similarly, the number of the limiting grooves 22 is set according to the number of the fasteners 411.

[0095] like Figure 2 , Figure 6 , Figure 8 and Figure 9 As shown, further, the lens 21 is located in the accommodating groove 122, so that the buckle portion 4112 is engaged with or separated from the outer wall of the lens 21. In this embodiment, the inner wall of the accommodating groove 122 is provided with a clearance opening 1221, and the clearance opening 1221 is connected to the sliding cavity 121, and the buckle portion 4112 is engaged with or separated from the outer wall of the lens 21 through the clearance opening 1221. It can be understood that in other embodiments, the inner wall of the accommodating groove 122 may not need to be provided with a clearance opening 1221. For example, one end of the lens 21 protrudes from the accommodating groove 122, that is, part of the lens 21 is located in the sliding cavity 121 and is engaged with or separated from the buckle portion 4112.

[0096] like Figure 2 and Figure 6 As shown, in one embodiment, the housing 100 includes a body 100a and a receiving portion 100b, the sliding cavity 121 and the groove 123 are both provided in the body 100a, and the receiving groove 122 is provided in the receiving portion 100b. The provision of the sliding cavity 121, the groove 123 and the receiving groove 122 facilitates the installation and arrangement of various components of the installation device 10, for example, the inner cylinder 200 is slidably installed in the sliding cavity 121, the lens 21 is movably accommodated in the receiving groove 122, and the locking mechanism 500 is respectively connected to the housing 100 and the inner cylinder 200 through the groove 123, so that the locking mechanism 500 locks or releases the inner cylinder 200 to the housing 100, and realizes that the locking mechanism 500 is respectively connected to the housing 100 and the inner cylinder 200.

[0097] like Figure 2 and Figure 6As shown, further, the outer shell 100 further includes a reinforcing portion 100c. The reinforcing portion 100c is respectively connected to the outer wall of the accommodating groove 122 and the inner wall of the main body 100a, improving the structural strength of the connection between the main body 100a and the accommodating portion 100b, and thus effectively improving the overall structural strength of the outer shell 100.

[0098] It should be noted that, in this embodiment, the outer shell 100 is an integrally formed structure, enabling the main body 100a, the accommodating portion 100b, and the reinforcing portion 100c to be firmly connected and making the structure of the outer shell 100 relatively compact. Specifically, the outer shell 100 is an integrally injection-molded structure. It can be understood that, in other embodiments, the outer shell 100 is not limited to an integrally formed structure. For example, the main body 100a, the accommodating portion 100b, and the reinforcing portion 100c are each formed and fixedly connected by welding or gluing.

[0099] As Figure 2 and Figure 6 shown, further, the expanding members 412 are respectively connected to the inner wall of the main body 100a and the outer wall of the accommodating portion 100b, not only improving the structural strength of the connection between the main body 100a and the accommodating portion 100b, but also making the structure of the installation device 10 relatively compact. Further, the expanding members 412, the main body 100a, the accommodating portion 100b, and the reinforcing portion 100c are integrally formed structures, enabling the expanding members 412, the main body 100a, the accommodating portion 100b, and the reinforcing portion 100c to be firmly connected, making the structure of the outer shell 100 relatively compact, improving the structural strength of the outer shell 100, and avoiding the situation where the structure of the expanding members 412 is damaged due to the impact force when the inner cylinder 200 is released.

[0100] As Figure 2 and Figure 6 shown, further, the expanding members 412 are in a wedge shape or a convex arc shape. In this embodiment, the expanding members 412 are in a wedge shape, that is, the expanding members 412 are in an inclined block shape. Specifically, the expanding members 412 are provided with a wedge-shaped surface 4121, and the wedge-shaped surface 4121 is inclined at a preset angle toward the outside of the accommodating portion 100b. The sliding portion 4113 is slidably connected to the wedge-shaped surface 4121. Thus, during the process of the limiting mechanism 400 separating from the outer wall of the lens 21, the sliding portion 4113 slides along the wedge-shaped surface 4121 and separates from the lens 21 better. In this embodiment, the preset angle is equal to the deformation angle. Further, the preset angle of the wedge-shaped surface 4121 is 15 degrees to 60 degrees, enabling the sliding portion 4113 to separate from the lens 21 better when sliding along the wedge-shaped surface 4121. In other embodiments, the expanding members 412 may also be in a convex arc shape. For example, the expanding members 412 are in an arc shape or a non-uniform curvature convex arc shape.

[0101] As Figure 2 and Figure 6As shown, further, the avoidance opening 1221 is formed in the accommodating portion 100b, and the buckle portion 4112 is located within the avoidance opening 1221, enabling the buckle portion 4112 to better act on the limiting groove 22 of the lens 21 during the process of the limiting mechanism 400 engaging or disengaging from the outer wall of the lens 21, and at the same time making the structure of the mounting device 10 more compact. In this embodiment, each spreading member 412 includes two spreading member units 412a arranged in parallel with each other. The wedge-shaped surfaces 4121 of the two spreading member units 412a are located in the same plane. The two spreading member units 412a are respectively located on both sides of the avoidance opening 1221. Each spreading member unit 412a is respectively connected to the accommodating portion 122 and the main body 100a. Sliding portions 4113 are provided on both sides of the buckle portion 4122. The sliding portions 4113 on both sides of the buckle portion 4112 are respectively slidably connected to the two spreading member units 412a. The buckle portion 4112 is located at the corresponding position of the avoidance opening 1221, enabling the sliding portions 4113 of the buckle portion 4112 to slide more smoothly along the spreading member 412, and at the same time enabling the buckle portion 4112 to better act on the limiting groove 22 of the lens 21 during the process of the limiting mechanism 400 engaging or disengaging from the outer wall of the lens 21, reducing the overall volume of the mounting device 10, making the structure of the mounting device 10 more compact, and at the same time avoiding interference and collision between the buckle portion 4112 and the accommodating portion 100b during the process of the buckle portion 4112 engaging or disengaging from the outer wall of the lens 21.

[0102] As Figure 2 , Figure 6 , Figure 8 and Figure 9 shown, specifically, in this embodiment, the two sliding portions 4113 are symmetrically arranged on both sides of the buckle portion 4112. The symmetric arrangement of the sliding portions 4113 on both sides can make the stress uniform, avoid wear and fatigue caused by uneven stress, and thus extend the service life of the buckle member 411. In other embodiments, the number of spreading member units 412a of each spreading member 412 is not limited to two and can also be one. The number of sliding portions 4113 of each buckle portion 4112 is adapted to the number of spreading member units 412a. Further, the portion of the sliding portion 4113 that slides on the surface of the wedge-shaped surface 4121 is a curved surface structure or a flat surface structure. In this embodiment, the portion of the sliding portion 4113 that slides on the surface of the spreading plate is a curved surface structure, reducing the risk of mechanical interference when the sliding portion 4113 slides on the surface of the wedge-shaped surface 4121. Specifically, the cross-section of the sliding portion 4113 is circular or elliptical.

[0103] As Figures 6 to 9As shown in the figure, further, an end face of the accommodating portion 100b located inside the sliding cavity 121 is convexly provided with a guiding portion 413. The guiding portion 413 is provided with a guiding sliding surface 4131, and the guiding sliding surface 4131 extends to the wedge-shaped surface 4121. The extending direction of the guiding sliding surface 4131 is parallel to the axial direction of the accommodating portion 122. When the buckling portion 4112 is buckled to the outer wall of the lens 21, the sliding portion 4113 abuts against the guiding sliding surface 4131, and the buckling portion 4112 is located in the avoiding opening 1221 and buckled to the outer wall of the lens 21. When disassembling the lens 21, the locking and elastic mechanism 500 releases the inner cylinder 200 from the outer shell 100 and drives the sliding portion 4113 to slide relative to the expanding member 412 in a direction away from the light-emitting mechanism 300. That is, when the locking and elastic mechanism 500 drives the inner cylinder 200 to slide relative to the main body in a direction close to the accommodating portion 100b, the sliding portion 4112 slides into the wedge-shaped surface 4121 through the guiding sliding surface 4131, so that the sliding portion 4113 slides more smoothly into the wedge-shaped surface 4121 until the buckling portion 4112 is separated from the outer wall of the lens 21. Further, the guiding portion 413, the expanding member 412, the main body 100a, the accommodating portion 100b, and the strengthening portion 100c are integrally formed structures, so that the guiding portion 413, the expanding member 412, the main body 100a, the accommodating portion 100b, and the strengthening portion 100c are firmly connected, the structure of the outer shell 100 is relatively compact, the structural strength of the outer shell 100 is improved, and the situation that the structure of the expanding member 412 is damaged due to the impact force when the inner cylinder 200 is released is avoided.

[0104] It can be understood that in other embodiments, the limiting mechanism 400 is not limited to the mechanical buckling mechanism 410. For example, in another embodiment, the limiting mechanism 400 is an electric control buckling mechanism (not shown in the figure).

[0105] Of course, in other embodiments, the limiting mechanism 400 is not limited to the buckling mechanism. For example, as Figure 4 shown, in another embodiment, the limiting mechanism 400 is a ball mechanism. The limiting mechanism 400 is connected to the inner wall of the outer shell 100 and is used to elastically engage or separate from the outer wall of the lens 21. Compared with the buckling mechanism, the ball mechanism has a simple structure and occupies less space.

[0106] As Figure 4As shown, in one embodiment, the limiting mechanism 400 is a mechanical ball mechanism 420. In this embodiment, the limiting mechanism 400 includes an elastic member 421 and a ball 422. A chute 423 is formed on the inner wall of the outer shell 100. The ball 422 is slidably disposed in the chute 423. One end of the elastic member 421 is connected to the inner wall of the chute 423, and the other end of the elastic member 421 is connected to the ball 422. When the lens 21 slides relative to the receiving groove 122 to a predetermined position, the ball 422 engages with the outer wall of the lens 21; there is an included angle between the elastic force direction of the elastic member 421 and the elastic force direction of the locking ball mechanism 500, and the elastic force of the elastic member 421 is less than the elastic force of the locking ball mechanism 500. When the lens 21 is installed in the receiving groove 122, the inner cylinder 200 slides relative to the outer shell 100 in a first direction to a first predetermined position. At this time, the ball 422 slides into the limiting groove 22 on the outer wall of the lens 21, so that the limiting mechanism 400 engages with the outer wall of the lens 21; when the lens 21 is removed from the receiving groove 122, the inner cylinder 200 slides relative to the outer shell 100 in a second direction to a second predetermined position. At this time, the ball 422 slides out of the limiting groove 22, so that the limiting mechanism 400 separates from the outer wall of the lens 21; the first direction is opposite to the second direction.

[0107] In this embodiment, when the lens 21 is installed to the predetermined position, the ball 422 engages with the lens 21 to fix the lens 21 in the receiving groove 122; when the lens 21 is pressed again, the locking ball mechanism 500 releases the inner cylinder 200 from the outer shell 100. The inner cylinder 200 slides relative to the outer shell 100 in the second direction. The elastic force of the elastic member 421 is less than the elastic force of the locking ball mechanism 500, so that the lens 21 is separated from the ball 422, and the lens 21 is removed from the receiving groove 122. Since the ball 422 is slidably disposed in the chute 423, it is avoided that the elastic member 421 fails to be limited due to the gravity sag of the ball 422 deviating from the engaging direction. Further, the chute 423 is disposed opposite to the avoidance port 1221 and is communicated with the avoidance port 1221. In this embodiment, the elastic member 421 is a helical spring or an elastic rubber strip. Specifically, the elastic member 421 is a helical spring, so that the elastic member 421 has good elastic strength. One end of the elastic member 421 is welded to the ball 422, and the other end of the elastic member 421 is welded to the outer shell 100.

[0108] In one embodiment, the process of loading and unloading the lens 21 to and from the mounting device 10 is as follows:

[0109] When installing the lens 21, the user pushes the lens 21 through the receiving groove 122, so that the lens 21 abuts against the inner cylinder 200 and pushes the inner cylinder 200 to slide relative to the outer shell 100 in the first direction. The outer wall of the lens 21 presses the marbles 422 into the sliding grooves 423 to compress and deform the elastic member 421. The lens 21 is installed to a predetermined position, and the elastic member 421 resets to eject the marbles 422 from the sliding grooves, so that the marbles 422 of the limiting mechanism 400 are engaged with the outer wall of the lens 21. At the same time, the inner cylinder 200 acts on the elastic component 510 to cause elastic deformation of the elastic component 510, and at the same time locks the inner cylinder 200 relative to the outer shell 100 through the locking component 520.

[0110] When removing the lens 21, the user pushes the inner cylinder 200 again, so that the locking component 520 releases the inner cylinder 200 relative to the outer shell 100. The elastic component 510 resets and pushes the inner cylinder 200 to slide relative to the outer shell 100 in the second direction. The thrust received by the lens 21 is greater than the elastic force of the elastic member 510, pressing the marbles 422 into the sliding grooves 423, so that the marbles 422 of the limiting mechanism 400 are separated from the outer wall of the lens 21. At this time, the lens 21 is taken out.

[0111] In one embodiment, the number of the sliding grooves 423, the marbles 422 and the elastic members 421 is two. The two sliding grooves 423 are respectively located on opposite sides of the inner wall of the outer shell 100. The two marbles 422 and the two elastic members are correspondingly arranged in the two sliding grooves 423, so that the mechanical marble mechanism 420 is more stable when engaging or separating the lens 21, and tilting during the installation process is avoided. In this embodiment, limiting grooves 22 are opened on opposite sides of the outer wall of the lens 21, and the two marbles 422 are used for engaging or separating in the limiting grooves 22 on opposite sides of the lens 21. It should be noted that the number of each component of the mechanical marble mechanism 420 is not limited to two, and can also be one or three or other numbers. The number of the limiting grooves 22 on the outer wall of the lens 21 is adaptively set according to the number of each component of the mechanical marble mechanism 420.

[0112] It can be understood that in other embodiments, the limiting mechanism 400 is not limited to the mechanical marble mechanism 420. For example, in another embodiment, the limiting mechanism 400 can also be a magnetic attraction marble mechanism (not shown in the figure). It should be noted that the limiting mechanism 400 to be protected in this application is not limited to the above-mentioned engaging or marble limiting methods, and can also be other alternative methods for engaging or separating the lens 21 in the receiving groove 122.

[0113] In a specific embodiment, the disassembly and assembly process of the lens 21 of the projection lamp 20 is as follows:

[0114] When installing the lens 21, the user pushes the lens 21 into the housing 100, makes the lens 21 abut against the inner cylinder 200, and pushes the inner cylinder 200 to slide relative to the housing 100 in the first direction, so that the locking pull rod 522 enters the labyrinth channel 523 of the locking block 521 and enters the high-low stop groove 5233 through the inclined line guiding groove 5231. The elastic component 510 generates elastic deformation under the action of the inner cylinder 200 until the locking pull rod 522 is clamped to the stop portion 5241 of the stop block 524, locking the inner cylinder 200 and the housing 100 together. Synchronously, the limiting mechanism 400 is engaged with the limiting groove 22 on the outer wall of the lens 21 to fixedly install the lens 21 in the installation device 10.

[0115] When disassembling the lens 21, the user pushes the lens 21 in the housing 100 again, makes the inner cylinder 200 slide relative to the housing 100 in the first direction again, so that the locking pull rod 522 disengages from the stop portion 5241 of the stop block 524 and enters the high-low stop groove 5233, and then disengages from the locking block 522 through the straight guiding groove 5232. The housing 100 and the inner cylinder 200 are unlocked and the inner cylinder 200 is released. The elastic component 510 resets to make the inner cylinder 200 slide relative to the housing 100 in the second direction, pushing the lens 21 out of the housing 100, so that the limiting mechanism 400 is separated from the limiting groove 22 on the outer wall of the lens 21, and the lens 21 is separated and removed from the installation device 10.

[0116] Compared with the prior art, the present disclosure has at least the following advantages:

[0117] 1. When the lens is installed in the accommodation groove, the locking and elastic mechanism locks the inner cylinder to the housing. At this time, the limiting mechanism is engaged with the outer wall of the lens to fix the lens in the accommodation groove; when the lens is disassembled from the accommodation groove, the locking and elastic mechanism releases the inner cylinder from the housing. At this time, the limiting mechanism is separated from the outer wall of the lens, so that the lens is separated from the accommodation groove; in this way, there is no need to disassemble the installation device during the process of replacing the lens, that is, there is no need to disassemble the installation device during the process of disassembling or installing the lens, which greatly improves the disassembly and replacement efficiency of the lens and realizes the effect of quick replacement of the lens;

[0118] 2. Since the light-emitting end of the light-emitting mechanism is arranged towards the accommodation groove through the light-emitting port, and the accommodation groove movably accommodates the lens. When the lens is installed in the accommodation groove, the light emitted by the light-emitting end of the light-emitting mechanism can be projected through the lens in the accommodation groove. Also, since the disassembly and replacement efficiency of the lens is greatly improved, the convenience of using the projection lamp is improved.

[0119] The above-described embodiments merely represent several implementation manners of the present disclosure. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
