The description which follows is a preferred embodiment for carrying out the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.

Referring to fig. 1, fig. 1 is a schematic view illustrating a lamp assembly 100 before being mounted on a T-shaped bracket 200 according to an embodiment of the present disclosure. The lamp assembly 100 comprises a lamp 10 and a snap-in device 20. Referring to fig. 2, fig. 2 is a schematic structural diagram of an engaging device 20 according to an embodiment of the present application. The top of the lamp 10 is provided with a mounting portion 11. It is understood that, in the present embodiment, the mounting portion 11 is elongated as a whole. The mounting part 11 is provided with a strip-shaped groove 12. The engaging means 20 comprises a fixed member 21, a rotating member 23 and a connecting member 25. The fixing member 21 is disposed in the strip groove 12. The rotating member 23 is disposed on the fixed member 21 through the connecting member 25. The rotating member 23 includes a base 231 and two hooks 233 provided on the base 231. The two hooks 233 are arranged in a central symmetry with the center of the rotary member 23 as the center. When the rotating member 23 rotates to a first position relative to the fixing member 21, the two hooks 233 are engaged with the T-shaped bracket 200, and the lamp 10 is fixed on the T-shaped bracket 200. When the rotating member 23 rotates to a second position relative to the fixing member 21, the two hooks are separated from the T-shaped bracket 200, and the lamp 10 is separated from the T-shaped bracket 200.

The first position is a direction in which the extending direction of the rotating member 23 is substantially parallel to the extending direction of the fixing member 21. The second position is a direction in which the extending direction of the rotating member 23 is substantially perpendicular to the extending direction of the fixed member 21 as shown in fig. 2.

Therefore, the lamp 10 can be clamped on the T-shaped support 200 through the clamping device 20, or the lamp 10 is detached from the T-shaped support 200, so that the clamping device 20 and the T-shaped support 200 can be quickly clamped and separated, and the lamp is simple in actual operation and reliable in fixation.

Specifically, in one embodiment, the fixing member 21 is an elongated member, and the fixing member 21 is locked to the lamp 10. For example, the fixing member 21 is provided with a screw hole, and the bottom wall of the bar-shaped groove 12 is also provided with a screw hole, so that the fixing member 21 can sequentially pass through the screw hole of the fixing member 21 and the screw hole of the bottom wall of the bar-shaped groove 12 by a locking member such as a screw, and be locked to the lamp 10.

Further, in one embodiment, in order to further improve the locking force between the fixing member 21 and the strip-shaped groove 12, the strip-shaped groove 12 is configured in an inverted T shape. The fixing member 21 further includes a base 211 and two locking protrusions 213, the two locking protrusions 213 respectively extend from two sides of the bottom surface of the base 211, and a step is formed between the locking protrusions 213 and the base 211. It is understood that in other embodiments, the snap 213 and the base 211 may be on the same plane, and no step is formed between the snap 213 and the base 211. Whether or not a step is formed is mainly related to the structure of the strip-shaped groove 12, and is not limited herein. The two locking protrusions 213 are arranged in a central symmetry manner with the center of the fixing member 21 as the center. Specifically, referring to fig. 3 to 6, in the present embodiment, each of the locking protrusions 213 has a first arc surface 2131 and a second arc surface 2133 connected with each other. The first arc surface 2131 is an outer arc surface. The second arc surface 2133 is an inner arc surface. The radius of the first circular arc surface 2131 is smaller than the radius of the second circular arc surface 2133. The first arc surface 2131 is formed to extend from an end of one side of the base 211 in a tangential manner. The second arc surface 2133 is formed to extend from the other substantially middle portion of the base portion 211 in a direction substantially coincident with the first arc surface 2131. Thus, the two catches 213 resemble the streamlines of a fan blade. When the fixing member 21 is disposed in the strip-shaped groove 12, and the fixing member 21 is rotated by a preset angle relative to the strip-shaped groove 12, the two clamping protrusions 213 of the fixing member 21 are clamped with the two side walls of the strip-shaped groove 12, respectively. Therefore, the locking force between the fixing member 21 and the strip-shaped groove 12 can be further improved, and the fixing reliability between the engaging device 100 and the T-shaped bracket 200 can be further improved.

Further, in one embodiment, the base 211 is provided with a first through hole 2111 having a cylindrical shape. The substrate 231 is provided with a second through hole 2311, and the inner wall of the second through hole 2311 is provided with a first stop face 2313. The connecting element 25 is also correspondingly provided with a second stop face 251. The connecting member 25, the first through hole 2111 and the second through hole 2311 have the same diameter. The connecting member 25 passes through the first through hole 2111 and the second through hole 2311, and the first stop surface 2313 of the second through hole 2311 is matched with the second stop surface 251 of the connecting member 25, so that the connecting member 25 is in rotation-stopping connection with the rotating member 23. Because the first through hole 2111 of the base 211 is not provided with a stop surface, the connecting element 25 can rotate relative to the fixing element 21, and therefore, the rotating element 23 can rotate relative to the fixing element 21, so that the quick clamping and separation of the clamping device 20 and the T-shaped bracket 200 are realized, the practical operation is simple, and the fixation is reliable.

Specifically, in one embodiment, the substrate 231 is in the shape of a willow leaf. It is understood that in other embodiments, the shape of the substrate 231 is not limited to a willow-leaf shape, but may be square, circular, and other regular and irregular shapes, and is not limited thereto. The substrate 231 has two straight edges 2315 having central symmetry and two arc edges 2317 having central symmetry. The two straight edges 2315 are parallel to each other. The two straight edges 2315 and the two circular arc edges 2317 are connected in this order of the straight edge 2315, the circular arc edge 2317, the straight edge 2315 and the circular arc edge 2317. The two hooks 233 respectively extend vertically upward along the ends of the two straight edges 2315, are bent, and extend toward each other after being bent. Thus, the two hooks 233 are respectively U-shaped. The two hooks 233 respectively form an accommodating space therein for engaging with the T-shaped bracket 200.

Specifically, in one embodiment, each hook 233 has a first edge 2331 and a second edge 2333 that are contiguously disposed. The first edge 2331 is connected to one of the straight edges 2315 and is perpendicular to the straight edge. The second edge 2333 is connected to one of the circular edges 2317, and the second edge 2333 is parallel to the straight edge 2315. Thus, the first edge 2331 is disposed substantially perpendicular to the second edge 2333. The distance between the two first sides 2331 is equal to the width of the T-shaped bracket 200; the distance between the two second edges 2333 is less than the width of the T-shaped bracket 200. Therefore, the rotating part 23 can rotate relative to the fixing part 21, so that the clamping device 20 and the T-shaped bracket 200 can be quickly clamped and separated, and the fixing device is simple in actual operation and reliable in fixing.

It can be understood that, in this embodiment, the rotation directions of the circular arc edge 2317 and the first circular arc surface 2131 are consistent and are both instantaneous needle rotation directions. Thus, the space occupied by the engaging device 20 can be reduced. It is understood that, in other implementations, the rotation directions of the circular arc edge 2317 and the first circular arc surface 2131 may be opposite, and are not limited herein.

It is understood that in the present embodiment, the connecting member 25 is a rivet. It is understood that, in other embodiments, the connecting member 25 is only a shaft-type connecting member, and is not limited in particular.

Specifically, in one embodiment, the engaging device 20 further includes a limiting member 27. The stopper 27 is substantially square. It is understood that, in other embodiments, the shape of the limiting member 27 may be, but is not limited to, a square shape, a rectangle, a square, a circle, an irregular shape, and the like, and is not limited herein. The connecting member 25 passes through the limiting member 27, so that the limiting member 27 is located between the fixing member 21 and the rotating member 23. The rotation angle of the rotating member 23 relative to the fixing member 21 can be limited by the limiting member 27.

Specifically, in one embodiment, the limiting member 27 is provided with a first protrusion 271. One of the two catches 213 is provided with a second protrusion 2113. In this embodiment, the second protrusion 2113 is disposed on a side of the end of the locking protrusion 213 opposite to the second arc surface 2133. The first protrusion 271 and the second protrusion 2113 cooperate to define the rotation angle of the rotating member 23 relative to the fixing member 21.

Specifically, in one embodiment, the opposite ends of the two locking protrusions 213 form a receiving space 2115. The stopper 27 is disposed in the accommodating space 2115. The second protrusion 2113 protrudes from the locking protrusion 213 toward a side close to the accommodating space 2115. Thus, the first protrusion 271 and the second protrusion 2113 cooperate to define the rotation angle of the rotating member 23 relative to the fixed member 21.

Specifically, in one embodiment, the limiting member 27 is provided with a third through hole 273. A third stop surface 275 is arranged in the third through hole 273. The third stop surface 275 is also engaged with the second stop surface 251 of the connecting member 25, so that the limiting member 27 is connected to the connecting member 25 in a rotation-stop manner, and therefore, the limiting member 27 can rotate together with the rotating member 23, so that when the limiting member 27 rotates until the first protrusion 271 abuts against the second protrusion 2113, the rotating member 23 cannot rotate relative to the fixing member 21 any more, and at this time, the rotating member 23 can only rotate in an opposite direction relative to the fixing member 21.

Therefore, according to the lamp assembly and the clamping device thereof in the embodiment of the application, when the rotating piece rotates to the first position relative to the fixing piece, the two clamping hooks are clamped with the T-shaped bracket, and the lamp is fixed on the T-shaped bracket; when the rotating piece rotates to a second position relative to the fixing piece, the two clamping hooks are separated from the T-shaped support, and therefore the lamp is separated from the T-shaped support. Therefore, the quick clamping and separation of the clamping device and the T-shaped support are realized, the practical operation is simple, and the fixation is reliable.

In the embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
