Description

Technical Field

[0001] This application relates to the field of track lighting technology, and more specifically, to a connection structure between a track light tube and a tube cover. Background Technology

[0002] Track lights are lighting fixtures with adjustable illumination direction, widely used in shopping malls, supermarkets, exhibition halls, museums and other places.

[0003] Currently used track lights generally consist of a lamp tube and a lamp tube cover for protecting the inside of the lamp tube. However, most existing track lights use threaded or bolted connections between the lamp tube and the lamp tube cover. This makes disassembly and assembly inconvenient and can easily cause stripping of the threads during frequent disassembly and assembly, thereby reducing the connection stability between the track light lamp tube and the lamp tube cover.

[0004] To address the aforementioned issues, this application provides a connection structure between the track light tube and the tube cover. Utility Model Content

[0005] This application provides a connection structure between a track light tube and a tube cover, including a tube body, a tube cover on one side of the tube body, and an extension portion fixedly fitted onto the inner wall of the tube body near the tube cover. One side of the extension portion is partially movably fitted onto the inner wall of the tube cover facing the tube body. A fixing ring is fixedly fitted onto the inner wall of the tube cover. Both sides of one end face of the fixing ring are in contact with a locking arm. Both locking arms are U-shaped. One side of each locking arm has an insertion hole, and the other side of each locking arm is fixedly connected to the inner wall of the extension portion. Connecting parts are provided on both sides of the end face of the fixing ring near the locking arm, and the two connecting parts and the two locking arms are staggered.

[0006] The connector includes an arc-shaped strip located on one side of the end of the fixed ring. A limiting slide rod is slidably sleeved through the middle cavity of the arc-shaped strip. One end of the limiting slide rod is fixedly connected to the surface of the fixed ring, and the other end of the limiting slide rod is fixedly connected to a limiting piece. A return spring is fixedly installed at the connection between the limiting piece and the opposite end face of the arc-shaped strip. The return spring is sleeved on one side of the outer wall of the limiting slide rod. Insert rods are distributed on the side of the limiting slide rod near the fixed ring, and the insert rods are fixedly connected to one side surface of the fixed ring.

[0007] Furthermore, both the insertion hole and the insertion rod have a circular cross-section, and the insertion hole and the insertion rod are designed to be plugged into each other. The lateral thickness of the clamping arm on the side near the insertion hole is slightly less than the distance between the fixing ring and the arc strip.

[0008] Furthermore, a sealing sleeve is fixedly fitted onto one side of the outer wall of the extension. The sealing sleeve is located on one side of the lamp tube body, and the outer wall of the extension slides in contact with the inner wall of the lamp tube cover through the sealing sleeve.

[0009] Furthermore, a sealing gasket is fixedly installed on one end face of the lamp cover facing the lamp body, and one end face of the lamp cover abuts against the lamp body through the sealing gasket.

[0010] Furthermore, the outer circumference of the middle part of the lamp tube body is uniformly provided with multiple anti-slip grooves, and each anti-slip groove is a semi-circular strip-shaped groove structure.

[0011] Furthermore, an indicator arrow is provided on the outer surface of the lamp body near the lamp cover, and the indicator arrow is distributed on one side of the local anti-slip groove.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] In this application, the extension, fixing ring, clamping arm, and insertion hole provided between the lamp body and the lamp cover enable quick clamping and positioning between the lamp body and the lamp cover by cooperating with the arc strip, limiting slide rod, limiting piece, return spring, and insertion rod in the connecting parts on both sides. This allows for portable disassembly and assembly operations between the two parts, and avoids the problem of thread stripping that is easily caused by existing threaded or bolted connections, thereby improving the connection stability between the lamp body and the lamp cover.

[0022] Example:

[0023] This application discloses a connection structure between a track light tube and its cover. Please refer to [link / reference]. Figures 1 to 3 The lamp includes a lamp body 1, a lamp cover 2 on one side of the lamp body 1, and an extension part 3 is fixedly installed on the inner wall of the lamp body 1 near the lamp cover 2. One side of the extension part 3 is partially movably sleeved on the inner wall of the lamp cover 2 facing the lamp body 1. A fixing ring 4 is fixedly sleeved on the inner wall of the lamp cover 2. Both sides of one end face of the fixing ring 4 are in contact with a clamping arm 5. Both clamping arms 5 are designed with a "U" shape. One side of each clamping arm 5 is provided with an insertion hole 6, and the other side of each clamping arm 5 is fixedly connected to the inner wall of the extension part 3. Connecting parts are provided on both sides of the end face of the fixing ring 4 near the clamping arm 5, and the two connecting parts and the two clamping arms 5 are distributed in an alternating manner.

[0024] The connector includes an arc-shaped strip 7 located on one side of the end of the fixed ring 4. A limiting slide rod 8 is slidably sleeved through the inner cavity of the arc-shaped strip 7. One end of the limiting slide rod 8 is fixedly connected to the surface of the fixed ring 4, and the other end of the limiting slide rod 8 is fixedly connected to a limiting piece 9. A return spring 10 is fixedly installed at the connection between the limiting piece 9 and the opposite end face of the arc-shaped strip 7. The return spring 10 is sleeved on one side of the outer wall of the limiting slide rod 8. An insertion rod 11 is distributed on the side of the limiting slide rod 8 near the fixed ring 4. The insertion rod 11 is fixedly connected to one side surface of the fixed ring 4. The cross-section of the insertion hole 6 and the insertion rod 11 are both circular, and the insertion hole 6 and the insertion rod 11 are designed to be inserted and adapted. The lateral thickness of the clamping arm 5 near the insertion hole 6 is slightly less than the distance between the fixed ring 4 and the arc-shaped strip 7.

[0025] A sealing sleeve 12 is fixedly fitted onto one side of the outer wall of the extension portion 3. The sealing sleeve 12 is located on one side of the lamp housing 1, and the outer wall of the extension portion 3 slides in contact with the inner wall of the lamp housing cover 2 through the sealing sleeve 12. A sealing gasket 13 is fixedly installed on the end face of the lamp housing cover 2 facing the lamp housing 1, and the end face of the lamp housing cover 2 abuts against the lamp housing 1 through the sealing gasket 13. The sealing sleeve 12 and the sealing gasket 13 improve the sealing contact effect between the lamp housing 1 and the lamp housing cover 2, while preventing external... Dust and moisture can easily enter the interior of the lamp body 1, thereby effectively improving the service life of the track light itself. Multiple anti-slip grooves 14 are evenly distributed around the outer circumference of the middle part of the lamp body 1, and each anti-slip groove 14 is a semi-circular strip-shaped groove structure. The setting of multiple anti-slip grooves 14 can improve the contact anti-slip effect under manual screwing operation of the lamp body 1. An indicator arrow is provided on the outer surface of the lamp body 1 near the lamp cover 2, and the indicator arrow is distributed on the lateral side of the local anti-slip groove 14.

[0026] The implementation principle of this embodiment is as follows: In use, the two clamping arms 5 are horizontally staggered with the connector. Simultaneously, the lamp body 1 and lamp cover 2 are aligned, and the extension 3 is movably inserted into the inner wall of one side of the lamp cover 2. During this process, the sealing sleeve 12 on the outer wall of the extension 3 contacts the inner wall of the lamp cover 2, while one end of the lamp cover 2 abuts against the lamp body 1 through the sealing gasket 13. At this time, the end faces of the two clamping arms 5 near the insertion holes 6 contact the fixing ring 4. Using the indicator arrow on the outer surface of the lamp body 1, the lamp body 1 is rotated in the direction of the indicator arrow until the sides of the two clamping arms 5 near the insertion holes 6 abut against the outer walls of the two insertion rods 11. Then, the lamp body 1 is pulled laterally away from the lamp cover 2, thereby partially displacing the two arc-shaped strips 7 on one side of each clamping arm 5. This indirectly causes the two return springs 10 to compress and deform until the distance between the two arc-shaped strips 7 and the fixing ring 4 is greater than the lateral width of the insertion hole 6. Then, it is slightly twisted again in the direction of the arrow, so that the two clamping arms 5 near the insertion hole 6 respectively abut against the outer wall of the two limiting slide rods 8. This indirectly makes the insertion hole 6 on one side of the two clamping arms 5 laterally correspond to the two insertion rods 11. Then, under the reset action of the two return springs 10, the insertion hole 6 on one side of the two clamping arms 5 and the insertion rod 11 are simultaneously inserted and positioned, and the portable connection assembly operation between the lamp body 1 and the lamp cover 2 is completed. When it is necessary to disassemble the two, simply operate in the direction of the connection assembly between the lamp body 1 and the lamp cover 2 to complete the portable disassembly work. During this process, the lamp body 1 needs to be twisted in the opposite direction of the arrow.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
