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.

[0061] Example 1

[0062] like Figure 1-4 As shown, this utility model discloses an LED waterproof lighting lamp, which in this embodiment includes:

[0063] The lamp holder 10 can be mounted on a wall;

[0064] The lampshade 11 is detachably connected to the lamp holder 10;

[0065] LED light strip (not shown in the figure) can be installed on lamp holder 10;

[0066] In this embodiment, the lamp holder 10 is recessed to provide an LED light strip mounting area 100, which can be fixed in the mounting area 100. An internal thread is formed on the inner wall of the mounting area 100. The lamp cover 11 is provided with a connecting part 110 that is adapted to the mounting area. An external thread is provided on the outer wall of the connecting part 110. Therefore, the lamp cover 11 and the lamp cover 10 can be threaded together by the internal and external threads provided in the connecting part and the mounting area.

[0067] A waterproof structure is formed between the lampshade 11 and the lamp holder 10. The waterproof structure has an expansion end and a matching adapter groove, which are respectively provided on the lamp holder 10 and the lampshade 11.

[0068] The expansion end can be inflated or deflated by a gas source;

[0069] When the expansion end (i.e., the sealing airbag in this embodiment) is inflated, the volume of the expansion end expands and fills the adapter groove;

[0070] When the expansion end is evacuated, the volume of the expansion end shrinks, and its volume can shrink to at least less than the width of the adapter groove. That is, when the sealing airbag is depressurized, the annular adapter part (see below) of this embodiment can be removed from the annular sealing groove, thereby facilitating the removal of the lamp cover.

[0071] In this embodiment, the waterproof structure includes:

[0072] An annular sealing groove 20 is recessed at the contact end a between the lamp cover 11 and the lamp holder 10;

[0073] An annular limiting groove 21 is formed on both sides of the annular sealing groove 20 and extends circumferentially, wherein the annular sealing groove 20 and the annular limiting groove 21 form a matching groove.

[0074] An annular adapter 22 is disposed on the lamp holder 10 and is adapted to the annular sealing groove 20;

[0075] Annular mounting grooves are formed on the inner ring sidewall b and the outer ring sidewall c of the annular adapter 22, respectively.

[0076] The sealing airbag 23 is located in each annular mounting groove;

[0077] The lamp holder 10 has an air supply branch 25 that communicates with the sealing airbag 23, and a control air valve 3 is provided at the bottom of the lamp holder 10.

[0078] In this embodiment: the control valve 3 includes:

[0079] The valve body 30 has a valve cavity 31 that communicates with the gas supply branch 25;

[0080] The expansion groove 32 is formed on the side wall of the valve cavity 31;

[0081] The valve core 33 is slidably connected to the telescopic groove 32, and is partially pushed out of the telescopic groove 32 by the spring 34 located in the telescopic groove 32 and comes into contact with the cavity wall of the valve cavity 31.

[0082] A limiting groove 35 is formed on the cavity wall of the valve cavity 31 and is used to insert one end of the valve core 33;

[0083] The pressure relief hole 36 is formed on the valve body 30 and extends through the bottom of the limiting groove 35 into the valve body 30.

[0084] In this embodiment, the other end of the valve body 30 is provided with an external thread to facilitate threaded connection of the external pipeline and to allow it to be supplied with air by an air pump.

[0085] refer to Figure 1-4 The principle of this embodiment is:

[0086] During installation, place the LED light strip in the mounting area of ​​the lamp holder, align the annular sealing groove on the lamp cover with the annular adapter on the lamp holder, and use the connecting part on the lamp cover to connect it to the mounting area via threads to complete the installation of the lamp cover and lamp holder. After installation, connect the external pipeline to the valve body, and then use the pressure relief needle (refer to Embodiment 2, which will not be repeated in this embodiment) to push open the valve core through the pressure relief hole and open the valve chamber. At this time, the air pump can send gas into the sealing airbag through the valve chamber and the air supply branch, causing the sealing airbag to expand and be stuck in the annular limiting groove, and tightly abut against the groove wall of the annular limiting groove to complete the inflation work. Then, release the pressure relief needle, and one end of the valve core is stuck in the limiting groove by the spring, and at the same time, the pressure relief hole and the valve chamber are closed, completing the installation of the lamp holder and lamp cover.

[0087] In this embodiment, the connection between the lampshade and the lamp holder is more reliable through this installation method. This is mainly reflected in the threaded connection between the lampshade's connecting part and the installation area, as well as the double fastening method where the sealing airbag is inflated and inserted into the annular limiting groove, thereby improving the reliability of the connection.

[0088] In addition, by expanding the sealing airbag and contacting the annular limiting groove, it can form at least two sealing barriers between the contact surfaces of the lamp cover and the lamp holder, namely: the sealing airbag located on the outer ring side wall of the annular adapter and the annular limiting groove, and the sealing airbag located on the inner ring side wall and the annular limiting groove, thereby improving the sealing effect of the lamp cover and the lamp holder, and thus achieving the purpose of waterproofing.

[0089] During venting, simply insert the pressure relief needle through the pressure relief hole and open the valve core to vent the sealing airbag. After the sealing airbag is vented, the annular adapter can be removed from the annular sealing groove. If necessary, an air pump can be used to completely remove the gas from the sealing airbag, causing it to retract into the annular mounting groove. This way, the sealing airbag will not affect the rotation and disassembly of the lamp cover.

[0111] refer to Figure 5-8 The principle of this embodiment is:

[0112] In order to conceal the control valve, this embodiment features an embedded structure in the lamp holder, as shown in the reference. Figure 6-7 In this embodiment, the embedded seat can slide within the embedded groove. During the sliding process, the ball bearing (and positioning part) of the positioning structure is engaged in the first positioning groove or the second positioning groove. The control air valve is located on the embedded seat, thereby driving the control air valve to move out of the embedded groove or retract into the embedded groove. The positioning structure cooperates with the first positioning groove to stop the embedded seat and the control air valve from moving. The positioning structure cooperates with the second positioning groove to expose the control air valve in the embedded groove, which facilitates the connection of the control air valve to the external pipeline.

[0113] In addition, this embodiment also provides a sealing structure to seal the groove opening of the embedded groove. During sealing, the sealing cover is fixed to the lamp holder with bolts, and the sealing layer covers the groove opening of the embedded groove to achieve a sealing effect.

[0114] It is worth noting that, in order to facilitate the use of the control valve, a pressure relief needle is also provided in the embedded seat in this embodiment.
