[0033] Reference Figures 1 to 6 A lamp fixture with a resilient retaining bead includes a lamp holder 100, a lamp body 200, and a retaining bead assembly 300. The lamp body 200 is detachably connected to the lamp holder 100. The retaining bead assembly 300 includes a base 310, a retaining bead 320, and an elastic member 330. The retaining bead 320 is movably disposed on the base 310 and can extend and retract relative to the base 310. The elastic member 330 is disposed on the base 310 and configured to cause the retaining bead 320 to tend to push outward toward the base 310. The locking bead assembly 300 is disposed in one of the lamp holder 100 and the lamp body 200. The other of the lamp holder 100 and the lamp body 200 is provided with a locking part 210. The locking bead 320 engages with the locking part 210 and restricts the separation of the lamp body 200 and the lamp holder 100. The locking part 210 is provided with a first guide surface 211. When the lamp body 200 moves in a direction relative to the lamp holder 100, the first guide surface 211 can guide the locking bead 320 to retract into the base 310 so that the locking bead 320 and the locking part 210 can separate from each other.

[0034] The above-described lamp fixture, by setting the retaining bead assembly 300, ensures a tight and secure connection between the lamp body 200 and the lamp holder 100 during assembly, through the snap-fit ​​engagement of the retaining bead 320 and the snap-fit ​​part 210, making it less prone to loosening. Furthermore, by configuring the first guide surface 211, when disassembling the lamp body 200 and the lamp holder 100, the first guide surface 211 can guide the retaining bead 320 to automatically retract, thereby not affecting the quick disassembly of the lamp body 200 and the lamp holder 100.

[0035] Specifically, in the embodiment, the lamp holder 100 is provided with a plug-in portion 110, and the lamp body 200 is provided with a plug-in hole 220. The plug-in portion 110 and the plug-in hole 220 are detachably plugged in and engaged. The bottom of the plug-in hole 220 is provided with a pin hole 230. The end face of the plug-in portion 110 opposite to the bottom of the plug-in hole 220 is provided with a pin portion 120. The peripheral surface of the pin portion 120 is provided with an installation hole. The seat 310 of the retaining bead assembly 300 is installed in the installation hole. The retaining bead 320 can extend and retract radially along the pin portion 120 and has a tendency to move radially outward. The pin hole 230 is a through hole. The retaining portion 210 is the part surrounding the pin hole 230. The pin portion 120 is plugged in and engaged with the pin hole 230. The retaining bead 320 is engaged around the inner opening of the pin hole 230. The first guide surface 211 is provided on the peripheral wall of the inner opening of the pin hole 230. It is conceivable that the positions of the plug portion 110 and the plug hole 220 can also be interchanged, that is, the plug portion 110 can be located on the lamp body 200, and the plug hole 220 can be located on the lamp holder 100. With the above structure, the fit between the lamp body 200 and the lamp holder 100 is more secure. It is understood that the radial direction of the pin portion 120 refers to the direction perpendicular to the circumference of the pin portion 120.

[0036] In this embodiment, to facilitate assembly, a second guide surface 212 is provided on the peripheral wall of the outer opening of the pin hole 230. The second guide surface 212 can guide the retaining bead 320 to retract into the seat 310 during the process of inserting the pin part 120 into the pin hole 230, so that the retaining bead 320 can be engaged in the inner side of the pin hole 230.

[0037] In this embodiment, the first guide surface 211 and the second guide surface 212 are chamfered surfaces at the opening of the pin hole 230, which have a simple structure and are easy to manufacture. It is conceivable that the first guide surface 211 and the second guide surface 212 could also be curved surfaces, which could also achieve the guiding function.

[0038] In this embodiment, the plug-in part 110 is a non-circular structure, and the plug-in hole 220 is adapted to the shape of the plug-in part 110, thereby enabling the lamp holder 100 and the lamp body 200 to be installed at an angle.

[0039] In this embodiment, the elastic element 330 in the ball retainer assembly 300 is specifically a spring. The seat 310 is provided with a receiving hole, and the ball retainer 320 is located in the receiving hole. A retaining ring is provided at the opening of the receiving hole to prevent the ball retainer 320 from falling out. The two ends of the spring abut against the ball retainer 320 and the bottom of the receiving hole. It is conceivable that the elastic element 330 in the ball retainer assembly 300 is not limited to a spring; for example, a torsion spring or other elastic structure can also be used.

[0040] In this embodiment, multiple lamp bodies 200 are provided, and the lamp holder includes a central support 101 and multiple sub-supports 102 that correspond one-to-one with the lamp body 200. One end of the sub-support 102 is disposed on the central support 101, and the lamp body 200 cooperates with the other end of the corresponding sub-support 102.

[0041] Reference Figures 7 to 11 In another embodiment, the peripheral surface of the insertion portion 110 is also provided with a mounting hole and a retaining bead assembly 300 is mounted thereon. The retaining bead 320 of the retaining bead assembly 300 provided in the insertion portion 110 can extend and retract radially along the insertion portion 110 and has a tendency to move radially outward. The corresponding retaining portion 210 of the retaining bead assembly 300 located in the insertion portion 110 is a notch provided in the wall of the insertion hole 220, and the first guide surface 211 is the wall surface of the notch. It can be understood that the radial direction of the insertion portion 110 refers to the direction perpendicular to the peripheral surface of the insertion portion 110. By further providing the retaining bead assembly 300 on the insertion portion 110 and adaptably providing the corresponding retaining portion 210 in the wall of the insertion hole 220, the stability of the insertion fit between the lamp holder 100 and the lamp body 200 can be further increased.

[0042] In this embodiment, specifically, the wall surface of the notch is a spherical cap surface, so that when disassembling the lamp holder 100 and the lamp body 200, the retaining bead 320 can be guided to retract radially inward, thus not affecting the disassembly. It is conceivable that the wall surface of the notch can also be configured as a conical surface, which can also achieve the function of guiding the retaining bead 320 to retract.

[0043] In this embodiment, in the radial direction of the insertion hole 220, the retaining bead 320 elastically abuts against the wall of the recess without any gap, forming a gapless fit. This further prevents the insertion part 110 and the insertion hole 220 from becoming loose, resulting in better assembly tightness. It is understood that the radial direction of the insertion hole 220 refers to the direction perpendicular to the wall of the insertion hole 220.

[0044] In this embodiment, the retaining bead assemblies 300 are arranged in pairs on both sides of the insertion portion 110, and the retaining portion 210 is arranged in a one-to-one correspondence with the retaining bead assemblies 300. With the above structure, the retaining bead assemblies 300 have a better fastening effect.

[0045] In this embodiment, the bead 320 is a sphere. Of course, other shapes can also be configured according to the actual situation, such as a bullet-shaped cone.

[0046] In this embodiment, in order to facilitate the insertion of the bead assembly 300 into the recess during assembly, a guide groove 240 is provided on the wall of the insertion hole 220, and the recess is provided on the bottom wall of the guide groove 240. The guide groove 240 has a flared end near the outer end of the insertion hole 220.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
