[0049] like Figure 1-Figure 5 As shown, a button-type installation mechanism 100 is used in embedded lamps such as downlights, spotlights, ceiling lamps or ceiling lamps, and the whole is assembled by a button-type installation method. The button-type installation mechanism 100 includes a base 1, a light shield 2 and a lamp body 3, wherein a front ring 4 can be sleeved and installed on the outer side of the base 1, and a clip spring 5 can be fixedly installed on the front ring 4. The clip spring 5 is connected with an external installation foundation, such as a through hole opened in a ceiling, a suspended ceiling or a wall, so that the base 1 together with the front ring 4 can be installed on the external installation foundation.

[0050] The base 1 includes a base member 11 and a support member 12, wherein the base member 11 is an annular structure, the support member 12 extends from the base member 11, and a first accommodating cavity 120 is formed inside the support member 12 for mounting the light shield 2. The support member 12 includes a first connecting arm 121 and a button portion 122, wherein the first connecting arm 121 is formed protruding from the base member 11, and the two first connecting arms 121 are arranged facing each other.

[0051] In some embodiments, the support member 12 further includes an oblique block 123, which is respectively connected to the two first connecting arms 121. The button portion 122 is disposed between the two first connecting arms 121 and is located above the oblique block 123. The button portion 122 is an elastic plastic part, which can be elastically deformed relative to the oblique block 123, and the position of the end of the button portion 122 in the first accommodating cavity can be changed.

[0052] A gap may be formed between the button portion 122 and the oblique block 123 , that is, the button portion 122 is not completely tightly connected to the oblique block 123 , so that the gap has space for the button portion 122 to be deformed and pressed.

[0053] In some embodiments, the first connecting arm 121, the button portion 122 and the oblique block 123 of the base member 11 and the support member 12 are an integral structure. In some embodiments, the first connecting arm 121, the button portion 122 and the oblique block 123 of the base member 11 and the support member 12 are separate structures, and the various components can be connected together by bonding or ultrasonic welding.

[0054] In other embodiments, the base member 11 and the support member 12 are integrally injection molded structures; the first connecting arm 121 and the inclined block 123 of the support member 12 are integrally injection molded, and the button portion 122 can also be connected to the inclined block 123 by integral molding, or connected to the inclined block 123 by an elastic structure such as a torsion spring.

The light shield 2 is installed in the first accommodating cavity 120 of the support 12, and the light shield 2 is rotatably connected to the base 1, for example, by the cooperation of a slide rail and a slide groove, or by a screw member with a damping effect together with a sealing gasket. Since the base 1 is fixedly installed on the external mounting foundation, the light shield 2 can drive the lamp body 3 to rotate relative to the base 1, so that the light output angle of the lamp body 3 can be adjusted. A second accommodating cavity 20 is formed inside the light shield 2, and the light shield 2 includes a rotating portion 21 and a plug-in portion 22. The rotating part 21 has an arc block structure, and the shade 2 is connected to the base 1 through the rotating part 21. For example, the rotating part 21 is provided with an arc slide groove 210. Correspondingly, the base 1 is provided with an arc slide rail 124 on the first connecting arm 121. The arc slide groove 210 slides along the arc slide rail 124, and then the shade 2 can rotate relative to the base 1. The plug-in part 22 has a cavity structure similar to a prism, and the shade 2 is plug-connected with the lamp body 3 through the plug-in part 22.

[0056] The lamp body 3 is the functional main body of the button type installation mechanism 100, and includes a lamp holder 31 and a connection seat 32. The lamp holder 31 is a columnar structure, and a power supply component, a heat sink, and a light emitting component are installed inside the lamp holder 31. The connection seat 32 extends downward from the lamp holder 31 toward the light shield 2, and the connection seat 32 is also roughly a columnar structure, and the inner diameter of the connection seat 32 is smaller than the inner diameter of the lamp holder 31. The connecting base 32 is installed in the second accommodating cavity 20, and a first protrusion 321 and a second connecting arm 322 are provided on the side wall 320 of the connecting base 32. The second connecting arm 322 is plugged and connected with the plug-in portion 22, so that the light shield 2 and the lamp body 3 are detachably plugged and connected together; and the first protrusion 321 is detachably snap-connected with the button portion 122 of the base 1, that is, after the lamp body 3 and the light shield 2 are installed, the button portion 122 is snap-connected with the first protrusion 321, and the position of the lamp body 3 can be locked at this time so that it stands upright on the base 1; when the lamp body 3 needs to be rotated, the button portion 122 is pressed, and the button portion 122 is separated from the first protrusion 321, and the lamp body 3 is loosened from the base 1, and can be rotated with the light shield 2 so that the light can be emitted obliquely downward.

[0057] Specifically, in the light shield 2, the plug-in portion 22 is connected to the second accommodating cavity 20, and a slot body 221 and a limit block 222 are provided on the plug-in portion 22. The limit block 222 protrudes toward the second accommodating cavity 20, and the slot body 221 is a accommodating slot opened vertically downward. Correspondingly, the second connecting arm 322 is provided with a plug-in block 3221 and a first marble 3222. In the process of plugging and connecting the second connecting arm 322 with the plug-in portion 22, the plug-in block 3221 is plug-connected to the slot body 221, and the first marble 3222 is elastically connected to the limit block 222 in a resettable manner, that is, in the process of the second connecting arm 322 being plugged downward, the first marble 3222 first elastically retracts through the limit block 222 when it contacts the limit block 222, and then resets and is limited by the limit block 222.

[0058] like Figure 3 As shown, in the light shield 2 of the present embodiment, the cross section of the groove body 221 is a trapezoidal structure, and correspondingly, the plug-in block 3221 is also set to have a trapezoidal cross section; in other implementations, the cross sections of the groove body 221 and the plug-in block 3221 can also be set to be triangular, rectangular, circular or elliptical, etc. The light shield 2 is provided with a positioning groove 211 on the rotating part, and correspondingly, the connecting seat 32 is provided with a positioning block 323, and the positioning block 323 is connected with the positioning groove 211. When the connecting seat 32 is inserted into the second accommodating cavity 20, the positioning block 323 is connected to the positioning groove 211, which can play a guiding role, so that the connecting seat 32 can be smoothly connected to the light shield 2.

[0059] Continue to refer Figure 1 and Figure 2In the base 1 of this embodiment, the button portion 122 includes a support block 1221, a second protrusion 1222 and a pressing block 1223. The support block 1221 is connected to the oblique block 123, and the pressing block 1223 is elastically connected to the support block 1221 in a resettable manner; and the second protrusion 1222 is formed by protruding inward from the pressing block 1223 toward the first accommodating cavity 120. When the light shield 2 and the connecting seat 32 of the lamp body 3 are installed in the base 1, the second protrusion 1222 is snap-connected with the first protrusion 321, thereby locking the upright position of the lamp body 3.

[0060] The first connecting arm 121 extends inwardly toward the first accommodating cavity 120 to form an arc block 125, on which a second marble 126 is disposed, and the support member 12 is further provided with a clearance position 127 between the first connecting arms 121 on both sides, and the clearance position 127 is disposed opposite to the oblique block 123. When the lamp body 3 is irradiated obliquely downward, that is, the angle of the lamp head 31 is deflected, the light shield 2 partially protrudes from the clearance position 127.

[0061] refer to Figure 4 and Figure 5 The lamp holder 31 is provided with an edge 33 at the junction with the connecting seat 32, and the lamp holder 31 is provided with a serrated portion 34 at the edge 33 toward the base 1, and a plurality of limit grooves 341 are provided on the serrated portion 34. In some embodiments, the limit grooves 341 may be a continuously distributed serrated groove structure, or a continuously distributed arc groove structure. The limit grooves 341 are connected with the second marble 126. When the lamp body 3 needs to be rotated and adjusted, the lamp holder 31 is swung, and the second marble 126 will retract downward at this time; when the swung lamp holder 31 reaches a predetermined position, the second marble 126 will reset and rebound and engage in the limit groove 341, thereby locking the oblique downward position of the lamp body 3 to ensure that the position of the lamp holder 31 after rotation adjustment does not shift.

[0062] In the button-type mounting mechanism of the present embodiment, the lamp body and the light shield are detachably plug-in connected, specifically, the plug-in block of the first connecting arm is plug-in connected with the groove body of the plug-in part, and the first marble is matched with the limit block, so that the connecting seat of the lamp body is installed in the first accommodating cavity of the light shield; then the light shield is installed in the second accommodating cavity of the base, and the second protrusion of the button part is buckled and connected with the first protrusion of the lamp body to lock the upright position of the lamp body; when the angle adjustment is required, the second protrusion is separated from the first protrusion by pressing the pressing block of the button part, so that the lamp body is loosened from the base, and the light shield drives the lamp body to rotate relative to the base. After the rotation is completed, the second marble is matched with the limit groove to lock the oblique downward position of the lamp body, which can ensure that light is emitted from different angles as required.
