Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be combined arbitrarily to form new embodiments. .

Referring to FIGS. 1 to 3 , a track connector 1 for a track light according to a first embodiment of the present invention is shown, and the track connector 1 for a track light is used to realize the connection between the light source module 2 and the track 3 3, the track connector 1 for track lights includes a base 11, a top rod 12, an elastic member, a rotating member 14 and a positioning block 15, wherein the base 11 is used for sliding fit with the track groove of the track 3 , in order to play a guiding role, the base 11 is provided with an accommodating cavity, and the side wall of the accommodating cavity is provided with a first spiral groove 1111 . The rotating member 14 is rotatably installed in the accommodating cavity. The rotating member 14 is provided with a first guide member 1411 , and the first guide member 1411 is slidably matched with the first spiral groove 1111 to position and guide the rotating member 14 function, so that the rotating member 14 can rotate freely in the accommodating cavity and make it rotate more smoothly. The first end of the rotating member 14 is also provided with a positioning hole 1421. The extending direction of the positioning hole 1421 is parallel to the lengthwise extending direction of the rotating member 14. In this embodiment, the positioning hole 1421 is a blind hole, and the positioning hole 1421 A second guide groove 1422 is opened on the hole wall of the 2 , and the second guide groove 1422 includes a second helical groove 14222 . The second end of the rotating member 14 passes through the base 11 and is connected with the positioning block 15, which is exposed on the top of the base 11. The positioning block 15 is used for connecting with the support plate 31 of the track 3 and the bottom wall of the track 3 gap junctions formed between them. The first end of the ejector rod 12 can be movably inserted into the positioning hole 1421, and the first end of the ejector rod 12 is also provided with a second guide member 122, the second guide member 122 and the second guide groove 1422 have a second spiral The slot 14222 is slidably fitted, and the second end of the ejector rod 12 is exposed to the rotating member 14. At this time, a through hole can be opened on the base 11 at a position corresponding to the second end of the ejector rod 12 to communicate with the accommodating cavity, so as to It is convenient for the user to extend into the accommodating cavity through the through hole and exert a force on the ejector rod 12, so as to urge the ejector rod 12 to move upward. The elastic member is used to provide elastic support for the ejector rod 12 . Specifically, when a downward force is applied to the positioning block 15, the positioning block 15 pushes the rotating member 14 to make the rotating member 14 perform a spiral downward movement, thereby driving the second guide member 122 to slide to the first position of the second spiral groove 14222. At this time, the length direction of the positioning block 15 is perpendicular to or slightly inclined to the length direction of the base 11 (it can be understood that the length direction of the base 11 is parallel to the length direction of the track 3). When the force is applied, the second guide member 122 slides to the second end of the second helical groove 14222 . Due to the cooperation between the second guide member 122 and the second helical groove 14222 , the up and down movement of the ejector rod 12 can be converted into the helix of the rotating member 14 . The upward movement, at this time, the length direction of the positioning block 15 is parallel or slightly inclined to the length direction of the base 11, so that the positioning block 15 can switch positions, and then the track connector 1 for track lights can pass through the positioning block 15. The track 3 is reliably connected or disconnected from the track 3 , so as to realize convenient disassembly and assembly between the lamp and the track 3 .

When installing the track connector 1 for a track light of the present invention, the positioning block 15 is reset to the initial state, that is, the longitudinal direction of the positioning block 15 is parallel to or slightly inclined to the longitudinal direction of the base 11, so as to enable the positioning The block 15 is located between the two support plates 31 of the track 3, and then the base 11 is placed in the track 3. When the top surface of the base 11 is in contact with the support plate 31 on the track 3, an upward pressure is applied to the base 11. force to make the positioning block 15 close to the bottom wall of the track 3 until the positioning block 15 is in contact with the bottom wall of the track 3, so as to exert a downward force on the positioning block 15, so that the positioning block 15 pushes the rotating member 14 to perform a spiral downward motion The positioning block 15 is driven to rotate so that the length direction of the positioning block 15 is perpendicular or slightly inclined to the length direction of the base 11 , so that the positioning block 15 is embedded in the gap between the support plate 31 and the bottom wall of the rail 3 and is connected to the base 11 . The support plate 31 abuts to realize the reliable connection between the track connector 1 and the track 3 for the track light; when disassembling, the ejector bar 12 can be moved upward and the elastic member can be compressed by applying upward force to the ejector bar 12. The second guide member 122 can be slidably fitted with the second guide groove 1422 under the driving of the ejector rod 12, so that the second guide member 122 slides from the first end of the second helical groove 14222 to the second end of the second helical groove 14222, Due to the cooperation between the second guide member 122 and the second spiral groove 14222, the upward movement of the ejector rod 12 can be converted into the spiral upward movement of the rotating member 14, so that the positioning block 15 can switch positions under the driving of the rotating member 14. At this time, The length direction of the positioning block 15 is parallel to or slightly inclined to the length direction of the base 11 (at this time, under the action of the wedge between the elastic member and the rotating member 14, the second guide member 122 can be temporarily connected to the second helical groove 14222. The second end is fixed, so that the positioning block 15 is stably maintained in a state where its length direction is parallel or slightly inclined to the length direction of the base 11 ), the positioning block 15 is disengaged from the support plate 31 and is located between the two support plates 31 , Pull down the base 11 to realize disassembly. Therefore, the reliable connection or disconnection between the track connector 1 for the track light and the track 3 can be realized by using the principle that the positioning block 15 can be rotated to switch positions, so as to realize the convenient disassembly and assembly of the lamp, and the use is more convenient.

The guiding function of the rotating member 14 makes the spiral upward movement or spiral downward movement of the rotating member 14 smoother. In this way, during the disassembly process, the positioning block 15 can be disengaged from the support plate 31 on the track 3 first, and then rotated to switch positions. To be located between the two support plates 31 and not in contact with the support plate 31, the positioning block 15 is disconnected from the support plate 31 to realize disassembly. Such a structural design can avoid the occurrence of the positioning block 15 and the support plate 31 on the track 3. When the positioning block 15 is reset, the rotating member 14 can perform a spiral downward movement, so that the positioning block 15 can be reliably abutted with the support plate 31 on the track 3, so as to achieve Reliable connection between the track connector 1 and the track 3 for the track light.
