[0039] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to the claims without some or all of these specific details. In other instances, well known methods, procedures and components have not been described in detail so as not to unnecessarily obscure aspects of the present application.

[0041] Referring to Figures 1 to 9 As shown in the drawings, some embodiments of the present application provide a lamp, which comprises a lamp body 1 and a hanger 2, and the hanger 2 is installed on the lamp body 1. Specifically, the hanger 2 can be connected with a hanger installed on a ceiling or a wall to realize quick assembly of the lamp on the ceiling or the wall. The lamp can be a ceiling lamp or other types of lamps.

[0042] In the lamp, the lamp body 1 is provided with a mounting hole 111, and the hanger 2 is movably installed in the mounting hole 111. A guide structure is arranged between the hanger 2 and the lamp body 1 to enable the hanger 2 to move up and down along the axial direction of the mounting hole 111 when the hanger 2 is rotated. The hanger 2 has at least a first rotation position and a second rotation position in the mounting hole 111, and the height position of the hanger 2 in the axial direction of the mounting hole 111 is different when the hanger 2 is in the first rotation position and in the second rotation position.

[0043] It should be noted that, for the convenience of description, the embodiments of the present application are described in the state that the lamp is horizontally placed, or in the state that the lamp is installed on the ceiling, or in the state that the axial line of the mounting hole 111 of the lamp body 1 is vertically arranged. The above-mentioned limitations are only for the convenience of description, and are not used to limit the structure and use scenarios of the lamp of the embodiments of the present application.

[0044] The lamp provided by the embodiments of the present application has the following advantages. The hanger 2 is movably installed in the mounting hole 111 of the lamp body 1, that is, the hanger 2 is arranged as a movable hanger 2, and a guide structure is arranged between the hanger 2 and the lamp body 1. When the hanger 2 is rotated, the hanger 2 can move up and down along the axial direction of the mounting hole 111 while rotating relative to the lamp body 1. In this way, the height position of the hanger 2 along the axial direction of the mounting hole 111 can be adjusted by rotating the hanger 2. The hanger 2 has at least a first rotation position and a second rotation position along the axial direction of the mounting hole 111. The height of the hanger 2 along the axial direction of the mounting hole 111 is different when the hanger 2 is in the first rotation position and when the hanger 2 is in the second rotation position. In this way, the hanger 2 has at least two different height positions along the axial direction of the mounting hole 111 by rotating the hanger 2. The hanger 2 can be adapted to a traction device of different height specifications when the hanger 2 is in different height positions, so that the hanger of the same lamp can be adapted to traction devices of different height specifications at the same time, improving the versatility of the lamp, making the installation of the lamp more convenient, and not needing to arrange a spring structure, which is simple in structure and low in cost.

[0045] In general, when a universal low traction device 3 needs to be adapted, referring to FIG. 6, the hanger 2 can be rotated to a relatively high height position (for example, the first rotation position). In this way, when the hanger 2 is connected with the universal low traction device 3, the distance between the top surface of the lamp body 1 and the ceiling can be increased, avoiding the problem that the distance between the top surface of the lamp body 1 and the ceiling is too small, which causes the lamp to be unable to be installed. Figure 6 Figure 7 In general, when a universal high traction device 4 needs to be adapted, referring to FIG. 7, the hanger 2 can be rotated to a relatively low height position (for example, the second rotation position). In this way, when the hanger 2 is connected with the universal high traction device 4, the distance between the top surface of the lamp body 1 and the ceiling can be reduced, avoiding the problem that the distance between the top surface of the lamp body 1 and the ceiling is too large, which affects the appearance and is easy to accumulate dust.

[0046] It should be noted that the hanger 2 in the mounting hole 111 of the lamp body 1 is not limited to having two rotation positions of the first rotation position and the second rotation position, but can have three rotation positions (or more rotation positions) in the mounting hole 111 of the lamp body 1 according to needs. The height position of the hanger 2 along the axial direction of the mounting hole 111 is different when the hanger 2 is in the three rotation positions (or more rotation positions), so that the hanger 2 of the same lamp can be adapted to traction devices of three (or more) different height specifications, to better improve the versatility of the lamp.

[0047] In some embodiments, referring to FIG. 8, the hanger 2 can be provided with a plurality of mounting holes 112 arranged along the axial direction of the mounting hole 111. In this way, the hanger 2 can be adapted to traction devices of different height specifications by rotating the hanger 2 to different mounting holes 112. Figures 4 to 9 ​As shown, the guide structure comprises a guide chute 10 and a limiting pin 221; the limiting pin 221 is arranged on the outer circumferential surface of the hanger 2, at least part of the chute wall of the guide chute 10 is formed on the hole wall of the mounting hole 111 and extends obliquely along the circumferential direction of the mounting hole 111, and the limiting pin 221 is movably arranged in the guide chute 10. In this way, by rotating the hanger 2, the limiting pin 221 can move in the obliquely extending guide chute 10, so that the limiting pin 221 has both a circumferential movement component along the mounting hole 111 and an axial movement component along the mounting hole 111, thereby enabling the hanger 2 to move up and down along the axial direction of the mounting hole 111 while rotating relative to the lamp body 1.

[0048] It should be noted that, in order to facilitate the assembly of the limiting pin 221 in the guide chute 10, the guide chute 10 can be formed by splicing two structural members together. For example, the lamp body 1 comprises a first structural member and a second structural member, the first structural member is provided with the mounting hole 111, and part of the chute wall of the guide chute 10 can be formed on the hole wall of the mounting hole 111, for example, only one side of the chute wall of the guide chute 10 is formed on the hole wall of the mounting hole 111, the other side of the chute wall of the guide chute 10 is formed on the second structural member, the hanger 2 is inserted into the mounting hole 111, and the limiting pin 221 on the hanger 2 is located at a position corresponding to one side of the chute wall of the guide chute 10, then the second structural member is fixed to the first structural member, and the first structural member and the second structural member are spliced together to form the guide chute 10, and the limiting pin 221 is limited in the guide chute 10.

[0049] Of course, in specific implementations, the guide chute 10 can also be formed integrally on the hole wall of the mounting hole 111. In this scheme, the limiting pin 221 can be inserted into the guide chute 10 in the form of extrusion deformation.

[0050] In addition, in specific implementations, the limiting pin 221 is not limited to being arranged on the hanger 2, and the guide chute 10 can be arranged on the lamp body 1, or the guide chute 10 can be arranged on the hanger 2, and the limiting pin 221 can be arranged on the lamp body 1. For example, the guide chute 10 is arranged on the outer circumferential surface of the hanger 2 and extends obliquely along the axial direction of the hanger 2, and the limiting pin 221 is arranged on the hole wall of the mounting hole 111 of the lamp body 1 and protrudes outward, and the limiting pin 221 is inserted into the guide chute 10 and can slide along the guide chute 10.

[0051] In addition, in specific embodiments, the guide structure is not limited to the structure of the limiting pin 221 cooperating with the guide sliding groove 10, but can also adopt a structure of an internal thread cooperating with an external thread. Illustratively, the outer circumferential surface of the hanger 2 is provided with an external thread, the hole wall of the mounting hole 111 of the lamp body 1 is provided with an internal thread, and the hanger 2 is threadedly connected with the mounting hole 111 of the lamp body 1. By rotating the hanger 2, the hanger 2 can be moved up and down along the axial direction of the mounting hole 111 of the lamp body 1, and the above-mentioned purpose can also be achieved.

[0052] In some embodiments, referring to Figure 4 and Figure 5 , Figure 8 and Figure 9 , the lamp body 1 includes a lamp body cover plate 11 and a connecting cover 12, and the connecting cover 12 is fixedly connected with the lamp body cover plate 11. The lamp body cover plate 11 is used to support a light source driving circuit board 13 (which can also be referred to as a lamp disc), that is, the light source driving circuit board 13 can be mounted on the lamp body cover plate 11. The connecting cover 12 is fixedly connected with the lamp body cover plate 11, and the connecting cover 12 is used to fix the hanger 2 on the lamp body cover plate 11.

[0053] Specifically, referring to Figure 4 and Figure 5 , Figure 8 and Figure 9 , the lamp body cover plate 11 is provided with a mounting hole 111, the hole wall of the mounting hole 111 is formed with a limiting protrusion 112 extending along the circumferential direction of the mounting hole 111, and the connecting cover 12 is provided with a limiting protruding rib 121 corresponding to the limiting protrusion 112. The limiting protruding rib 121 is inserted into the mounting hole 111, and a guide sliding groove 10 is formed between the limiting protruding rib 121 and the limiting protrusion 112. In this way, the guide sliding groove 10 is formed by splicing two structural members, so as to facilitate the assembly of the limiting pin 221 in the guide sliding groove 10.

[0054] In specific embodiments, referring to Figure 4 and Figure 5 , Figure 8 and Figure 9The shown placement direction is an example, the lamp body cover plate 11 is provided with a mounting hole 111, a limiting convex part 112 extending along the circumference of the mounting hole 111 is formed on the hole wall of the mounting hole 111, the limiting convex part 112 is formed at the upper part of the mounting hole 111 along the axial direction, and a first guide inclined surface 113 extending along the circumference of the mounting hole 111 is formed on the lower surface of the limiting convex part 112; the guide hook 2 is inserted and mounted into the mounting hole 111 from the lower direction of the lamp body cover plate 11, the limiting pin 221 on the guide hook 2 is blocked by the limiting convex part 112 and is located below the limiting convex part 112; the connecting cover 12 is mounted onto the lamp body cover plate 11 from the lower direction of the lamp body cover plate 11, the top of the connecting cover 12 is formed with a limiting convex rib 121 extending upwardly and protruding, the limiting convex rib 121 is formed as an annular convex rib matched with the shape of the limiting convex part 112, a second guide inclined surface 122 extending along the circumference of the annular convex rib is formed on the upper surface of the annular convex rib, the limiting convex rib 121 is inserted into the mounting hole 111, the second guide inclined surface 122 and the first guide inclined surface 113 correspond and are spaced, and a guide sliding groove 10 is formed between the two; wherein the first guide inclined surface 113 is formed as one side groove wall of the guide sliding groove 10, and the second guide inclined surface 122 is formed as the other side groove wall of the guide sliding groove 10.

[0055] In some embodiments, referring to Figure 8 and Figure 9 The guide sliding groove 10 has opposite first and second groove walls, and at least one of the first and second groove walls is provided with a first limiting part and a second limiting part along the length direction; the guide hook 2 is rotated to the first rotating position, the first limiting part limits the limiting pin 221, and the guide hook 2 is rotated to the second rotating position, and the second limiting part limits the limiting pin 221.

[0056] In this way, in specific implementation, when the lamp is connected with the universal low traction device 3, the first limiting part is used to limit the guide hook 2 at the first rotating position, so as to ensure the reliability of the connection between the lamp and the traction device through the guide hook 2; when the lamp is connected with the universal high traction device 4, the second limiting part is used to limit the guide hook 2 at the second rotating position, so as to ensure the reliability of the connection between the lamp and the traction device through the guide hook 2.

[0057] In some embodiments, referring to Figure 8 and Figure 9As shown, the first limiting position and the second limiting position are respectively formed at the two ends of the length of the guide chute 10; the first limiting part includes a first limiting protrusion 101, which is adjacent to one end of the length of the guide chute 10, and the limiting pin 221 passes the first limiting protrusion 101 and rotates to the first limiting position; the second limiting part includes a second limiting protrusion 102, which is adjacent to the other end of the length of the guide chute 10, and the limiting pin 221 passes the second limiting protrusion 102 and rotates to the second limiting position.

[0058] In this way, when the limiting pin 221 passes the first limiting protrusion 101, the first limiting protrusion 101 will form resistance to the limiting pin 221, so that the limiting pin 221 is not easy to slide out of the first limiting position; when it is necessary to switch the position of the hitch 2, the hitch 2 can be slightly forced to rotate in the opposite direction, and the limiting pin 221 can pass the first limiting protrusion 101 in the opposite direction and slide out of the first limiting position. Similarly, when the limiting pin 221 passes the second limiting protrusion 102, the second limiting protrusion 102 will form resistance to the limiting pin 221, so that the limiting pin 221 is not easy to slide out of the second limiting position; when it is necessary to switch the position of the hitch 2, the hitch 2 can be slightly forced to rotate in the opposite direction, and the limiting pin 221 can pass the second limiting protrusion 102 in the opposite direction and slide out of the second limiting position. In this way, the structure is simple and the operation is convenient.

[0059] It should be noted that, in order to ensure the reliability of the limiting, limiting protrusions can be correspondingly provided on the first groove wall and the second groove wall to improve the limiting effect of the limiting pin 221, and a larger force is required to make the limiting pin 221 slide out of the first limiting position or the second limiting position.

[0060] In specific implementation, the first limiting protrusion 101 and the second limiting protrusion 102 can be arranged on the lower surface of the limiting protruding part 112 of the lamp body cover plate 11; the first limiting protrusion 101 and the second limiting protrusion 102 can also be arranged on the upper surface of the limiting protruding rib 121 of the connecting cover 12; or the first limiting protrusion 101 and the second limiting protrusion 102 can be arranged on both.

[0061] In some embodiments, the number of limiting pins 221 is at least two, and the limiting pins 221 are arranged in the circumferential direction of the hitch 2; the number of guide chutes 10 is equal to the number of limiting pins 221, and the guide chutes 10 are arranged one by one. In this way, the limiting connection points between the hitch 2 and the lamp body 1 are increased, so that the installation of the hitch 2 on the lamp body 1 is more stable and reliable.

[0062] Exemplarily, three limiting pins 221 are arranged on the outer circumferential surface of the lead-hanging device 2 at intervals, and three guide sliding grooves 10 are formed at intervals in the circumferential direction between the lamp body cover plate 11 and the connecting cover 12, and the three limiting pins 221 are movably arranged in the three guide sliding grooves 10, respectively.

[0063] It should be noted that the number of the limiting pins 221 and the guide sliding grooves 10 is not limited to the above, and can be two, four or more.

[0064] In some embodiments, referring to Figure 4 and Figure 5 , a knob part 222 for holding is arranged on the lead-hanging device 2, so as to switch the lead-hanging device 2 between the first rotating position and the second rotating position by rotating the knob part 222. In this way, the operation convenience of rotating the lead-hanging device 2 is improved by arranging the knob part 222.

[0065] In specific implementation, the knob part 222 can be a character-shaped knob part, and of course, can also be a knob part 222 of other shapes, such as a circular knob part.

[0066] In some embodiments, referring to Figure 2 , Figure 4 and Figure 5 , a hook part 211 is arranged on the lead-hanging device 2, and the hook part 211 is used for hooking and cooperating with a hooking groove arranged on a traction device. In this way, the lead-hanging device 2 is connected with the traction device in cooperation, and the operation is convenient, which is beneficial to realize the quick assembly of the lamp and the traction device.

[0067] Specifically, the traction device is usually provided with a hooking groove for hooking and cooperating with the lead-hanging device 2, and the hooking groove can be arranged as an arc-shaped groove. For the convenience of description, the hooking groove on the general low traction device 3 is referred to as a first hooking groove 31, and the hooking groove on the general high traction device 4 is referred to as a second hooking groove 41. When the lamp is hooked and cooperated with the general low traction device 3, the hooking part on the lead-hanging device 2 of the lamp is aligned and inserted into the first hooking groove 31 on the general low traction device 3, and then the lamp is rotated as a whole, so that the hooking part is hooked in the first hooking groove 31, and the hooking and cooperation of the lamp and the general low traction device 3 is realized. When the lamp is hooked and cooperated with the general high traction device 4, the hooking part on the lead-hanging device 2 of the lamp is aligned and inserted into the second hooking groove 41 on the general high traction device 4, and then the lamp is rotated as a whole, so that the hooking part is hooked in the second hooking groove 41, and the hooking and cooperation of the lamp and the general high traction device 4 is realized.

[0068] In addition, the hook part 211 on the lead-hanging device 2 can adopt a conductive structure, so as to realize the mechanical connection and the electrical connection of the lamp and the traction device by hooking and cooperating the hook part 211 with the hooking groove.

[0069] It should be noted that the matching connection structure between the hanger 2 and the puller can be set according to the existing matching connection structure, and the present application will not be repeated here.
