Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED spotlight clip structure. Background Technology

[0002] LED spotlights are spotlights that use light-emitting diodes as their light source. Compared with traditional halogen lamps, they have advantages such as energy saving and environmental protection, and therefore have been widely promoted and applied in various fields.

[0003] Currently, LED spotlights mainly consist of a lamp holder and a lamp cover (also known as a lens or lamp cap). However, the current lamp holder and lamp cover are only fixed together by a "click-fit structure," such as:

[0004] A snap-on LED spotlight disclosed in patent announcement number CN203375260U, with reference to its... Figure 1 It can be seen that it uses a "snap-fit ​​structure" to connect the lampshade and the lamp cup (i.e., the lamp holder);

[0005] For example, an LED spotlight disclosed in authorization announcement CN218209158U, refer to its... Figure 2-4 It can be seen that the cover (equivalent to a lampshade) and the lamp housing (which is the lamp holder) are also connected by a "snap-fit ​​structure".

[0006] In summary, it's easy to see that current LED spotlights all use this "clamp-on structure" for the connection between the lamp holder and the lamp cover. However, based on practical experience, while the "clamp-on structure" has the advantage of convenient installation, it is extremely prone to damage during use. It can maintain a certain lifespan if not disassembled for a long time after installation, but frequent disassembly during repair or replacement of the LEDs on the lamp holder easily damages the "clamp-on structure." Therefore, the current "clamp-on structure" (also called a snap-fit ​​structure) still has the drawback of a short lifespan and needs improvement. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an LED spotlight clip structure, which aims to solve the problems mentioned in the background technology.

[0008] The technical solution of this utility model is implemented as follows: an LED spotlight buckle structure, characterized in that it consists of a snap-fit ​​part fixed to the lens and a mounting part fixed to the lamp holder;

[0009] The mounting part and the snap-fit ​​part have at least a first connection mode and a second connection mode;

[0010] In the first connection mode, the snap-fit ​​part engages with the mounting part in the form of a threaded connection, and fixes the lens and lamp holder;

[0011] In the second connection mode, the snap-fit ​​part is threaded and snap-fitted into the mounting part to fix the lens and lamp holder.

[0012] By adopting the above technical solution:

[0013] The snap-fit ​​structure (also called snap-fit ​​structure or connection structure) of this utility model provides two modes for the lens and lamp holder to mate. In the first mode, the lamp holder and lens are connected by a threaded connection. Compared with the existing snap-fit ​​structure, the threaded connection is less prone to damage during frequent disassembly and thus has the advantage of a longer service life. In addition, if the threads wear during disassembly due to the threaded connection, this utility model also has a second connection mode. In this connection mode, a snap-fit ​​connection is added to the original threaded connection mode. That is, after the lamp holder and lens are threadedly connected, the snap-fit ​​structure is used to limit the lens and / or lamp holder to prevent them from loosening, thereby ensuring the stable installation of both.

[0014] Preferably, the mounting portion includes:

[0015] A ring-shaped mounting body is fixed to the lamp holder;

[0016] A limiting hole is formed on the annular mounting body and extends radially through the annular mounting body;

[0017] The limiting structure moves within the limiting hole and has a limiting end that can penetrate into the inner ring of the annular mounting body.

[0018] The inner wall of the annular mounting body is formed with internal threads.

[0019] Preferably, the snap-fit ​​portion includes:

[0020] A ring-shaped clip is fixed to the lens;

[0021] The annular limiting body is connected to the annular snap-fit ​​body and has a blind hole for the limiting end to snap into.

[0022] The outer wall of the annular snap-fit ​​body is provided with an external thread that matches the internal thread.

[0023] Preferably, the limiting structure includes:

[0024] The limiting body has one end that can be inserted through the limiting hole and positioned at the inner ring of the annular mounting body;

[0025] The limiting seat is connected to the limiting body;

[0026] The outer wall of the limiting seat and the inner wall of the limiting hole are provided with mutually compatible external threads and internal threads.

[0027] By adopting the above technical solution:

[0028] In this utility model, the first type of threaded connection is achieved by the internal thread of the annular mounting body engaging with the external thread of the annular snap-fit ​​body on the outer wall, thereby realizing the threaded connection between the lamp holder and the lens.

[0029] The second mode of this utility model is: a limiting body is added on the basis of the threaded connection between the lamp holder and the lens. The limiting body can pass through the limiting hole and cooperate with the blind hole on the annular limiting body. In this way, a limiting snap-fit ​​cooperation is added on the basis of the threaded connection between the lens and the lamp holder, thereby improving the cooperation effect between the lens and the lamp holder.

[0030] Preferably, the lamp holder has a storage cavity for accommodating the limiting structure, wherein the limiting seat includes:

[0031] The first body has a threaded cavity;

[0032] The first component is integrally formed with the first body and connected to the limiting body, and can be threadedly connected to the limiting hole.

[0033] The second body is provided with a threaded post that mates with the threaded cavity;

[0034] The second part is integrally formed with the second body and has a rubber plug that fits into the opening of the storage cavity.

[0035] Preferably, the limiting body comprises:

[0036] The limiting body is connected to the first split body;

[0037] The limiting head is connected to the end of the limiting body;

[0038] The outer wall of the limiting head is provided with several outer step surfaces distributed in a stepped manner, and the inner wall of the blind hole is provided with an inner step surface that cooperates with the outer step surfaces.

[0039] By adopting the above technical solution:

[0040] This utility model provides a storage cavity for placing a limiting structure, which can achieve the purpose of being ready to use and retrieve. In order to increase the sealing of the placement and the matching effect with the limiting hole, this utility model adopts multiple modular designs for the limiting structure, which is easy to disassemble and use. For details, please refer to the embodiment section of this utility model.

[0041] Furthermore, other advantages of this invention will be demonstrated in the embodiments section of this invention, thereby making the beneficial effects of this invention even more significant. Attached Figure Description

[0048] 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 protection scope of the present utility model. Example 1

[0049] like Figure 1-3 As shown, this utility model discloses an LED spotlight buckle structure, which in this embodiment consists of a snap-fit ​​part fixed to the lens 10 and a mounting part fixed to the lamp holder 11.

[0050] The mounting part and the snap-fit ​​part have at least a first connection mode and a second connection mode;

[0051] In the first connection mode, the snap-fit ​​part engages with the mounting part in the form of a threaded connection, and fixes the lens 10 and the lamp holder 11;

[0052] In the second connection mode, the snap-fit ​​part is threaded and snap-fitted into the mounting part to fix the lens 10 and the lamp holder 11.

[0053] In this embodiment, a boss 110 is formed in the lamp holder 11, and the boss 110 is for mounting LED lamp beads.

[0054] In this embodiment, the mounting part includes:

[0055] The annular mounting body 20 is fixed on the lamp holder 11;

[0056] A limiting hole 21 is formed on the annular mounting body 20 and radially penetrates the annular mounting body 20;

[0057] The limiting structure moves within the limiting hole 21 and has a limiting end that can penetrate into the inner ring of the annular mounting body 20.

[0058] The inner wall of the annular mounting body 20 is formed with a first internal thread 20a.

[0059] In this embodiment, the snap-fit ​​portion includes:

[0060] The ring-shaped snap-fit ​​body 30 is fixed on the lens 10;

[0061] The annular limiting body 31 is connected to the annular snap-fit ​​body 30 and has a blind hole 32 for the limiting end to snap into.

[0062] The outer wall of the annular snap-fit ​​body 30 is provided with an external thread 30a that is adapted to the first internal thread 20a.

[0063] In this embodiment, the limiting structure includes:

[0064] The limiting body 40 has one end that can be inserted through the limiting hole 21 and positioned at the inner ring position of the annular mounting body 20.

[0065] The limiting seat 41 is connected to the limiting body 40;

[0066] The outer wall of the limiting seat 41 and the inner wall of the limiting hole 21 are provided with mutually compatible external threads and second internal threads 41a.

[0067] In this embodiment, one end of the limiting body 40 forms a limiting end 40b, which is adapted to the blind hole 32.

[0068] In this embodiment, when the limiting structure is not in use, a rubber plug with a shape similar to the limiting seat can be used to seal the limiting hole.

[0069] refer to Figure 1-3 The principle of this embodiment is:

[0070] In this embodiment, the LED beads can be installed on the protrusion of the lamp holder. The installation method can be any known form. Furthermore, the lamp holder should be provided with a power supply part (such as a wire structure) to supply power to the LED beads. The power supply part of the lamp holder and the installation method of the LED beads are currently relatively mature existing technologies, so they will not be described in detail in this embodiment.

[0071] The core of this embodiment lies in the connection method between the lens and the lamp holder. Compared with the existing technology, this embodiment changes the previous snap-fit ​​connection method (which is prone to damage) and adopts a threaded connection to match the lens and the lamp holder. Furthermore, the threaded connection method of this embodiment can also be matched with the snap-fit ​​connection (i.e., the limiting structure of this embodiment limits the lens and the lamp holder), thereby improving the connection stability between the lamp holder and the lens.

[0072] In some applications, a threaded connection can be used to fit the lampshade (lens) and the lamp holder together.

[0073] In other application scenarios, such as after disassembling the lens and lamp holder, wear on the internal and external threads can cause the fit between the lamp holder and the lens to become loose. In this case, a limiting structure can be used. That is, after the lens and lamp holder are threaded together, a limiting body is inserted through the limiting hole, and one end of the limiting body is inserted into the blind hole. This limits the annular limiting body on the lens and the lens itself, thereby ensuring a tight connection between the lamp holder and the lens.

[0074] In summary, the snap-fit ​​structure of this embodiment (the limiting structure is "snap" and the threaded connection is "buckle") has a longer service life compared to existing snap-fit ​​connections, and there is no need to worry about the lens and lamp holder becoming loose after disassembly and maintenance.

[0075] Example 2 differs from Example 1 in that...

[0076] like Figure 4-5 As shown, in this embodiment: a storage cavity 5 for placing a limiting structure is formed on the lamp holder 11. In this embodiment, the storage cavity 5 is recessed from the top end face of the lamp holder 11. The limiting seat 41 includes:

[0077] The first body 61 is provided with a threaded cavity 610;

[0078] The first split part 62 is integrally formed with the first body 61, and is connected to the limiting body 40, and can be threadedly connected to the limiting hole 21.

[0079] The second body 63 is provided with a threaded post 64 that mates with the threaded cavity 610;

[0080] The second part 65 is integrally formed with the second body 63 and has a rubber plug 66 that fits into the opening of the storage cavity 5.

[0081] In this embodiment: the limiting body 40 includes:

[0082] The limiting body 400 is connected to the first split body 62;

[0083] The limiting head 401 is connected to the end of the limiting body 400;

[0084] The outer wall of the limiting head 401 is provided with a plurality of outer step surfaces 401a distributed in a stepped manner, and the inner wall of the blind hole is provided with an inner step surface that mates with the outer step surface (not shown in the figure, but it can be adapted to the outer step surface 401a).

[0085] refer to Figure 4-5 The principle of this embodiment is:

[0086] This utility model features a storage cavity on the lamp holder for the insertion of a limiting structure, achieving the purpose of immediate retrieval upon use. The operating principle of the limiting structure is as follows:

[0087] refer to Figure 5 When the limiting structure is not used (i.e., the limiting structure is placed in the storage cavity), the second body is disassembled from the first body, and the limiting body connected to the first body is placed into the storage cavity. The rubber plug on the second body is then used to seal the opening of the storage cavity, thus completing the storage of the limiting structure.

[0088] When using the limiting structure, remove the rubber plug at the cavity opening and take out the limiting body. Then assemble the second body and the first body. When the assembly is complete, the end face of the rubber plug on the side facing the limiting body should be at least flush with the end face of the first body facing the rubber body. In this state, insert the limiting body through the limiting hole and use the threaded connection between the first split body and the limiting hole to complete the installation of the limiting body. When the installation is complete, the rubber plug contacts the periphery of the limiting hole, which can also improve the sealing performance of the installation of the limiting body and the limiting hole.

[0089] It is worth mentioning that: in this embodiment, the outer stepped surface formed by the outer wall of the limiting head and the inner stepped surface formed by the inner wall of the blind hole can improve the matching effect between the limiting head and the blind hole, thereby ensuring the matching between the lens and the lampshade.

[0090] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
