[0008] In one embodiment, the limiting structure further includes: A first perimeter is provided at one end of the second connecting portion away from the first connecting portion. The first perimeter extends around the second sealing portion and is used to restrict the axial movement of the sealing member along the gland. The second periphery protrudes from the periphery of the first connecting portion and extends around the first sealing portion. The second periphery is used to restrict the radial movement of the seal along the gland.

[0009] In one embodiment, the gland and the seal are integrally injection molded structures.

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] This technical solution proposes a projection lamp, including: The housing 100 has a light-emitting area, and a socket 10 is provided on one side of the housing 100, which is connected to the interior of the housing 100. The projection component 200 is disposed inside the housing 100 and is used to project light onto the light-emitting area. The slide 300 is inserted into the housing 100 through the insertion hole 10, and the slide 300 is positioned in the light path; A pressure cap 400 is provided at the insertion hole 10 and is detachably fixed to the outer casing 100; The sealing element 500 is integrated with the gland 400, and the gland 400 and the socket 10 are sealed together by the sealing element 500.

[0023] In this technical solution, the insertion hole 10 provided on the side wall of the outer casing 100 forms a replacement channel for the projection sheet 300. When it is necessary to change the projection effect, the projection sheet 300 can be replaced without disassembling the main body of the outer casing 100. In addition, compared with the process that requires separate installation of the sealing ring and the pressure cover 400 during assembly, this solution combines the two assembly processes into one step through the integrated design of the sealing element 500 and the pressure cover 400, reducing the assembly complexity. Moreover, the positions of the sealing element 500 and the pressure cover 400 remain relatively fixed before and after disassembly and assembly, which simplifies the structure and improves the sealing reliability.

[0024] Specifically, such as Figures 1 to 8The projection lamp has a housing 100, which is designed as the exterior component of the projection lamp or as a supporting body. The housing 100 has an internal cavity for housing the light source and other components of the projection lamp. The overall shape of the housing 100 can be circular, square, or any other arbitrary shape. A light-emitting area is provided on one side wall of the housing 100. The light-emitting area can be implemented using a window structure covered by transparent or semi-transparent material. For example, an opening is made in the housing 100 and a transparent cover is placed over the opening. Inside the housing 100 is a projection component 200, which is an optical module that can generate and project light. Specifically, it can be implemented using a combination structure of a light source and a lens. The projection component 200 can project light to the outside through the light-emitting area. The projection sheet 300 can be a light-transmitting sheet structure with patterns or textures, specifically a film or similar structure. The projection sheet 300 can be placed in the path of the light projected by the projection component 200. The light passes through the projection sheet 300 and is projected to the outside, thus creating the desired light and shadow effect. Additionally, a socket 10 is provided on the housing 100. The socket 10 is an opening structure on the side wall of the housing 100, specifically a rectangular hole or similar structure, whose size and shape are adapted to the projection sheet 300. Furthermore, the projection sheet 300 can... The projector 300 is fixed to the inner wall of the outer casing 100 by plugging it in, so that the outer casing 100 does not need to be disassembled. Users can plug and unplug the projector 300 through the plug hole 10 to switch different projection effects. The cover 400 is a structure used to seal the plug hole 10 to seal the outer casing 100 and improve the waterproof effect. The cover 400 can be implemented by metal or plastic parts with snap-fit ​​or threaded connection. The seal 500 is an elastic element provided on the cover 400. Specifically, it can be a silicone sealing ring structure integrally formed with the cover 400. In use, the cover 400 is fixed to the socket 10 by a snap or screw. When the cover 400 closes the socket 10, the seal 500 fits tightly against the edge of the socket 10. During the assembly process, the cover 400 is compressed and deformed to fill the assembly gap between the cover 400 and the socket 10, thus forming a seal. When the projector 300 needs to be replaced, simply open the cover 400, remove the old projector 300, insert the new projector 300, and close the cover 400 again. Throughout the process, the relative positions of the cover 400 and the seal 500 remain fixed, eliminating the positioning deviation during the assembly of the separate sealing ring and ensuring a stable and consistent seal every time the cover 400 is closed. In addition, through the integrated design of the seal 500 and the cover 400, the two assembly processes can be combined into one step during the assembly of the projector lamp, reducing assembly complexity and improving sealing reliability while simplifying the structure.

[0025] like Figure 3 and Figure 4One structural form of the seal 500 is shown. In this embodiment, the seal 500 includes a first sealing portion 510 and a second sealing portion 520. The first sealing portion 510 is arranged around the outside of the second sealing portion 520. The seal 500 engages with the periphery of the socket 10 to clamp the first sealing portion 510, and the seal 500 engages with the inner wall of the socket 10 to clamp the second sealing portion 520.

[0026] The second sealing part 520 is annular and can be sleeved and fixed on the pressure cover 400. The first sealing part 510 is an annular sealing structure formed around the outer edge of the second sealing part 520. Both the first sealing part 510 and the second sealing part 520 can be made of materials such as silicone. In order to simplify the process, in this solution, the first sealing part 510 and the second sealing part 520 can be integrally formed. During the installation of the cap 400, the first sealing part 510 is deformed by the contact surface between the cap 400 and the edge of the socket 10 of the outer shell 100, forming a continuous sealing area around the socket 10. At the same time, the second sealing part 520 extends into the socket 10, and the cap 400 also extends into the socket 10 and cooperates with the inner wall of the socket 10 to clamp the second sealing part 520. The second sealing part 520 is compressed radially by the socket 10 and fits tightly against the inner wall of the socket 10. In the above assembly process, the first sealing part 510 and the second sealing part 520 are pressed simultaneously in a single assembly action, without the need to install independent sealing rings or apply sealant in steps, which facilitates assembly. Moreover, the first sealing part 510 and the second sealing part 520 form seals on the periphery of the socket 10 and the inner wall of the socket 10, respectively, increasing the sealing area and forming two lines of defense, thus ensuring the success rate of waterproofing.

[0027] In addition, such as Figure 5 As shown, in another embodiment, to further improve the sealing effect, a first protrusion 511 is provided on the end face of the first sealing part 510 facing the insertion hole 10. The first protrusion 511 can extend around the insertion hole 10. During assembly, the first protrusion 511 can be compressed and deformed, which can increase the contact area between the first sealing part 510 and the periphery of the insertion hole 10 and improve the pressing force between them, which helps to improve the waterproof success rate. Similarly, a second protrusion 521 is provided on the side of the second sealing part 520 facing the inner wall of the insertion hole 10. The second protrusion 521 can extend around the circumference of the second sealing part 520 and can tightly abut against the inner wall of the insertion hole 10, which can also improve the waterproof effect. Moreover, multiple second protrusions 521 can be spaced apart in the axial direction of the insertion hole 10, and multiple second protrusions 521 respectively cooperate with different positions of the inner wall of the insertion hole 10, which can further improve the waterproof effect.

[0028] like Figure 4The diagram illustrates one structural form of the pressure cap 400. In this embodiment, the pressure cap 400 includes a first connecting portion 410 and a second connecting portion 420 protruding from the first connecting portion 410. A second sealing portion 520 is sleeved on the second connecting portion 420. The first connecting portion 410 abuts against the outer shell 100 and engages with the periphery of the insertion hole 10 to clamp the first sealing portion 510. The second connecting portion 420 extends into the insertion hole 10 and engages with the inner wall of the insertion hole 10 to clamp the second sealing portion 520.

[0029] The first connecting part 410 is square, specifically a metal plate or a plastic plate, with an outer diameter larger than the perimeter of the insertion hole 10. A through hole may be provided on the first connecting part 410 for fixing it to the outer casing 100 with bolts. The second connecting part 420 is located in the middle of the first connecting part 410 and is a columnar protrusion. The second connecting part 420 can be inserted into the insertion hole 10 and fits with the internal clearance of the insertion hole 10. To simplify the structure, the first connecting part 410 and the second connecting part 420 can be integrally formed. The second sealing part 520 has a cylindrical structure and is included in the second connecting part. On the outer periphery of part 420, a first sealing part 510 is disposed on the second sealing part 520 near one end of the first connecting part 410. The first sealing part 510 is annularly arranged and fits against the first connecting part 410. During assembly, the second sealing part 520 is inserted into the socket 10 along with the second connecting part 420. Under the cooperation of the socket 10 and the second connecting part 420, it is squeezed and deformed, and tightly fits against the inner wall of the socket 10 and the outer wall of the second connecting part 420. The first sealing part 510 is squeezed by the first connecting part 410 and fits against the periphery of the socket 10, thus achieving a seal. In this solution, the pressure cap 400 adopts the above structure, which facilitates assembly, and the fit between the sealing element 500 and the pressure cap 400 is tighter, ensuring a sealing effect.

[0030] In one embodiment of this utility model, a limiting structure is connected between the sealing element 500 and the pressure cap 400 to fix the relative position of the sealing element 500 and the pressure cap 400. The limiting structure constrains and fixes the relative position between the sealing element 500 and the pressure cap 400, ensuring that the position between the sealing element 500 and the pressure cap 400 is relatively stable when the pressure cap 400 is inserted or removed, thus ensuring a sealing effect. The limiting structure can be a structure of mutually cooperating protrusions and grooves, with one of the protrusions and grooves provided on the sealing element 500 and the other on the pressure cap 400. When the sealing element 500 and the pressure cap 400 are assembled, the protrusion can be inserted into the groove to form a limiting position, thereby restricting the relative position of the sealing element 500 and the pressure cap 400. By setting the limiting structure, the positional error between the sealing element 500 and the pressure cap 400 can be reduced, ensuring that the sealing element 500 maintains its sealing effect during long-term use and improving the reliability of the seal.

[0031] like Figure 4The configuration of the limiting structure is shown. In this embodiment, the limiting structure includes: a limiting groove 630 disposed on the second connecting portion 420; and a limiting portion 640 disposed on the second sealing portion 520 on the side facing the second connecting portion 420, with the limiting portion 640 extending into the limiting groove 630. The limiting groove 630 can be a recessed structure machined on the surface of the second connecting part 420, which can extend along the axial direction of the second connecting part 420. The cross-sectional shape can be flexibly designed according to requirements. The limiting part 640 can be a protruding structure integrally formed on the surface of the second sealing part 520, and its shape and size are adapted to the limiting groove 630. The limiting part 640 can be embedded in the limiting groove 630 to restrict the rotation of the second sealing part 520 on the second connecting part 420. It also restricts the radial movement of the sealing element 500 along the pressure cap 400 (radial direction is perpendicular to the direction in which the pressure cap 400 is inserted into the outer shell 100), and also ensures the reliability of the seal. In addition, the setting of the limiting part 640 and the limiting groove 630 can also provide a foolproof effect during the processing, so that the second sealing part 520 and the second connecting part 420 can only be connected at a unique angle, which improves the consistency of product production.

[0032] like Figure 4 In another embodiment of this application, the limiting structure further includes: The first perimeter 610 is provided on the second connecting portion 420 at one end away from the first connecting portion 410. The first perimeter 610 extends around the second sealing portion 520 and is used to restrict the axial movement of the sealing member 500 along the gland 400. The second periphery 620 is provided at the periphery of the first connecting portion 410. The second periphery 620 extends around the first sealing portion 510 and is used to restrict the radial movement of the sealing member 500 along the cover 400.

[0033] The first perimeter 610 is a protrusion formed along the end of the second connecting portion 420. Multiple first perimeters 610 can be spaced apart circumferentially around the second connecting portion 420. To simplify the process, the first perimeter 610 can be integrally molded with the second connecting portion 420 using injection molding. The first perimeter 610 abuts against the end of the second sealing portion 520 away from the first connecting portion 410, aiming to provide axial obstruction to the second sealing portion 520 and prevent the sealing element 500 from sliding along the axis of the second connecting portion 420 during the assembly of the gland 400. The second perimeter 620 is a protrusion located on the outer edge of the first connecting portion 410, protruding towards the first sealing portion 510. Multiple second perimeters 620 can be spaced apart circumferentially around the first connecting portion 410. The second perimeter 620 can also be injection molded with the first connecting portion 410. The function of the second perimeter 620 is to provide radial obstruction to the first sealing portion 510, limiting... The engagement of the groove 630 and the limiting part 640 restricts the radial displacement of the second sealing part 520 along the pressure cap 400, and the second perimeter 620 restricts the radial displacement of the first sealing part 510 along the pressure cap 400. The cooperation of these two sets of structures can prevent the sealing part 500 from shifting laterally when the pressure cap 400 and the outer shell 100 are locked together, thus ensuring the fitting accuracy of the pressure cap 400 and the sealing part 500 and improving the reliability of their connection. In addition, when the pressure cap 400 and the outer shell 100 are assembled, the first perimeter 610 restricts the radial deformation of the first sealing part 510, making the first sealing part 510 abut more tightly against the periphery of the socket, while the second perimeter 620 restricts the axial deformation of the second sealing part 520, making the second sealing part 520 abut more tightly against the inner wall of the socket. Thus, the arrangement of the first perimeter 610 and the second perimeter 620 can further improve the sealing effect and waterproof performance.

[0034] In another embodiment of this utility model, the gland 400 and the seal 500 are integrally injection molded structures. The gland 400 is made of rigid plastic, and the seal 500 is made of flexible plastic. They can be integrally molded using processes such as two-color injection molding. This allows for a seamless, continuous structure between the gland 400 and the seal 500, further ensuring a good seal. Furthermore, integrating the gland 400 and the seal 500 into a single component eliminates the assembly process, helping to optimize costs and improve production efficiency.

[0035] like Figure 2 As shown, in one embodiment of the present invention, the outer shell 100 includes: a shell 110, which has a receiving cavity, the receiving cavity having a first opening and a second opening, the projection assembly 200 and the projection sheet 300 being installed in the receiving cavity, and the insertion hole 10 being provided on the side wall of the shell 110; a front cover 120, which is sealed to the first opening, and the light-emitting area is provided on the front cover 120; and a rear cover 130, which is sealed to the second opening.

[0036] The housing 110 refers to the main structure that supports the projection assembly 200 and the projection sheet 300. Specifically, it can be an injection-molded plastic structure. The housing 110 has a receiving cavity with openings at both ends. The projection assembly 200 and the projection sheet 300 are both installed within the receiving cavity. Insertion holes 10 are provided on the side walls of the housing 110 for inserting the projection sheet 300. The openings at both ends of the housing 110 are a first opening and a second opening, respectively. A front cover 120 covers the first opening of the housing 110. The front cover 120 can be an injection-molded part with a light-transmitting hole, which can be located in the light-emitting area. The front cover 120 and the housing 110 can be locked together with screws, and a sealing ring can be clamped between them to ensure waterproofing. A rear cover 130 covers the second opening of the housing 110. The rear cover 130 can also be an injection-molded part. The rear cover 130 and the housing 110 can also be locked together with screws and sealed by a sealing element 500. This structure simplifies the structure of the housing 100 and facilitates the assembly of the projection lamp.

[0037] like Figure 6 and Figure 7 As shown, in another embodiment of the present invention, the front cover 120 includes: a first cover body 121, which is sealed to the first opening, and a light-transmitting hole is provided on the first cover body 121; a light-transmitting cover 122, which is provided at the light-transmitting hole to form a light-emitting area, and the light-transmitting cover 122 is used to allow light to pass through, and the light-transmitting cover 122 and the first cover body 121 are integrally injection molded structures.

[0038] The first cover 121 is a plate-shaped component covering the first opening, which can be injection molded from plastic. The first cover 121 is connected to the housing 110 by screws. A light-transmitting hole is formed on the first cover 121, through which the light generated by the projection component 200 is projected to the outside. A light-transmitting cover 122 is attached to the light-transmitting hole. The light-transmitting cover 122 can be a transparent or semi-transparent component. To simplify the assembly process and improve waterproof performance, the light-transmitting cover 122 and the first cover 121 can be integrally injection molded, so that the two are seamless. Additional assembly steps are required, and the assembly gap between the two is eliminated, improving waterproof performance. Furthermore, the light-transmitting cover 122 and the first cover 121 can be integrally molded using a two-color injection molding process. The light-transmitting cover 122 can be made of a light-transmitting material, while the first cover 121 can be made of an opaque material. This ensures that light can only pass through the light-transmitting cover 122 and will not leak from the first cover 121, guaranteeing projection effect. Additionally, users will not be able to see the internal components of the projection lamp through the first cover 121, improving aesthetics. Figure 7In another embodiment of this utility model, a first baffle 1211 can be provided around the light-transmitting hole. The first baffle 1211 can extend around the light-transmitting hole and form a stepped structure with the periphery of the light-transmitting hole. The light-transmitting cover 122 is disposed inside the first baffle 1211, and the side of the light-transmitting cover 122 is combined with the first baffle 1211. This can increase the area of ​​the connection between the light-transmitting cover 122 and the first cover 121, which helps to improve the reliability of the connection between the light-transmitting cover 122 and the first cover 121.

[0039] In addition, in such Figure 7 In another embodiment, a stepped structure may be provided on the inner wall of the housing 110 near the first opening, and the first cover 121 may be inserted into the housing 110 through the first opening. In addition, a second stop 1212 is provided on the periphery of the first cover 121 on the side opposite to the second opening. The second stop 1212 extends around the circumference of the first cover 121, so that an annular groove is formed between the second stop 1212 and the inner wall of the housing 110. During assembly, the groove can be filled with sealant to achieve a sealing fit between the first cover 121 and the housing 110. By adopting the above structure, the sealing ring between the first cover 121 and the housing 110 can be eliminated, which helps to simplify the structure while ensuring sealing performance.

[0040] like Figure 8 In another embodiment of the present invention, the back cover 130 includes: a second cover body 131, which is sealed to the second opening, and the second cover body 131 is provided with a mounting hole; and a button 132, which is disposed in the mounting hole, and the button 132 and the second cover body 131 are integrally injection molded structures.

[0041] The second cover 131 can be a plate-shaped component covering the second opening, specifically made of plastic. The second cover 131 and the housing 110 can be connected by screws, and a sealing ring can be provided between them to achieve a seal. A mounting hole is provided on the second cover 131, penetrating the second cover 131 and communicating with the receiving cavity. A button 132 can be embedded in the mounting hole. The button 132 can be pressed to activate the contacts on the internal projection component 200 to adjust the projection. In this solution, to simplify the structure and improve waterproofing, the button 132 can be made of an elastic material and can be integrally injection molded with the second cover 131. Specifically, for example... Figure 8The button 132 includes a connecting body 1321 and a pressing body 1322. The connecting body 1321 fits against the inner wall of the mounting hole and is integrated with the second cover 131 during injection molding. The pressing body 1322 is disposed on the connecting body 1321 and closes the mounting hole. The user can activate the contact point on the projection assembly 200 by pressing the pressing body 1322. With the above structure, the second cover 131 and the button 132 are manufactured as a single component simultaneously, eliminating the need for secondary assembly between the button 132 and the second cover 131, simplifying the assembly of the projection lamp. Furthermore, the assembly gap between the button 132 and the second cover 131 is eliminated, which helps improve the waterproof performance of the projection lamp. Additionally, as... Figure 8 In order to make the button 132 easier to press, a thinning groove 1323 can be provided around the periphery of the pressing body 1322. The thinning groove 1323 can extend around the periphery of the pressing body 1322, which makes the position of the thinning groove 1323 easier to deform, thereby making the button 132 easier to press and helping to improve the user experience.
