Description

Technical Field

[0001] Specifically, this utility model is a diverter joint for lighting fixtures. Background Technology

[0002] Lighting fixtures have evolved into various forms to meet diverse needs. Many of these fixtures possess clear directional properties, allowing for installation and adjustment of the illumination angle via a directional joint. Furthermore, with the continuous development of directional joints, damping mechanisms have been incorporated to allow the fixture to remain at any turning angle. However, the addition of damping mechanisms significantly increases the manufacturing and assembly processes of the directional joints. To ensure the stability of the damping mechanism's arrangement, the current structure uses a top-pressure damping mechanism connector secured with a snap ring. However, installing the snap ring within the confined space of the directional joint makes operation particularly difficult, greatly impacting the assembly and production of the directional joint. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a diverter joint for lamps.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A swivel joint for lighting fixtures includes a swivel head, a base, and a damping mechanism. The base includes a sleeve and a connector installed at the bottom of the sleeve. The swivel head is rotatably connected to the top of the sleeve. The damping mechanism is arranged inside the sleeve between the swivel head and the connector. The side wall of the connector has multiple through channels, each containing a retaining bead with a diameter greater than the channel length. A pusher is also installed on the top of the connector. The top of the pusher abuts against the damping mechanism, and the bottom extends into the inner side of the connector from the top. The outer wall of the pusher fits against the inner wall of the connector and covers the inner port of the channel. The sleeve has a slot for the retaining bead to be engaged at the corresponding channel position of the connector.

[0006] The bead has four evenly distributed rings, and the groove is an annular groove formed around the inner wall of the sleeve.

[0007] The outer wall of the pusher is provided with a tapered surface.

[0008] The bottom side wall of the pusher is provided with a clearance groove for the locking bead to be inserted. When the clearance groove and the through groove of the pusher are horizontally aligned, it is the initial installation state of the pusher.

[0009] An axial guide structure is also arranged between the connector and the sleeve.

[0010] The axial guide structure includes a protrusion arranged on the connector and a guide groove arranged axially on the inner wall of the sleeve. The protrusion is engaged in the guide groove when the connector is inserted from the bottom of the sleeve and can slide along the guide groove.

[0011] The protrusion and multiple locking beads are staggered in the height direction.

[0012] The protrusion is a ball bearing arranged above multiple retaining balls. The side wall of the connector also has a through channel corresponding to the ball bearing to allow the ball bearing to be movably installed. The sleeve has a track corresponding to the ball bearing for the ball bearing to travel.

[0013] The steering head is rotatably connected to the top of the sleeve via a rotating joint. The top of the sleeve is also provided with a limiting groove. The steering head passes through the limiting groove and can rotate arbitrarily within the angle range limited by the limiting groove under the limitation of the limiting groove.

[0014] The damping mechanism includes a spring and a limiting plate. The top of the limiting plate is provided with a groove that fits with the rotating joint of the steering head. One end of the spring presses against the bottom of the limiting plate, and the other end abuts against the top of the pushing member.

[0015] The beneficial effects of this utility model are as follows: This utility model sets multiple annular retaining beads that can move radially through the connector head to replace the clamping structure and realize the secure installation of the connector head. The multiple annular retaining beads are controlled to pass through by a pusher installed on the top of the connector head. When the connector head is installed into the bottom of the sleeve, the top of the pusher abuts against the bottom of the damping mechanism and gradually moves into place as the connector head is installed. The pusher is pressed into the connector head and the side wall of the pusher pushes the retaining beads from the side wall of the connector head into the grooves that are locked into the inner wall of the sleeve, thus realizing the secure installation of the connector head and the sleeve. The above assembly process is convenient to operate and effectively improves the assembly efficiency. Attached Figure Description

[0024] Reference Figures 1 to 7 A swivel joint for lighting fixtures includes a swivel head 1, a base, and a damping mechanism 4. The base includes a sleeve 2 and a connector 3 installed at the bottom of the sleeve 2. The swivel head 1 is rotatably connected to the top of the sleeve 2 via a rotating joint 11. The top of the sleeve 2 is also provided with a limiting groove 24. The swivel head 1 passes through the limiting groove 24 and connects to the lighting fixture. The size of the groove 24 limits the rotation angle of the swivel head and forms a limited range of rotation angle. Under the limiting condition, it can rotate arbitrarily within the limited range, such as 90° or 180°. The damping mechanism 4 is arranged inside the sleeve 2 between the steering head 1 and the connector 3. It includes a spring 41 and a limiting plate 42. The top of the limiting plate 42 has a groove that fits against the rotating joint 11 of the steering head 1. One end of the spring 41 presses against the bottom of the limiting plate 42, and the other end is limited and installed above the connector 3. The spring 41 continuously applies force to push the limiting plate 42, so that the limiting plate 42 tightly presses against the rotating joint 11, causing the rotating joint 11 to be limited and stop at the current rotation angle. The connector 3, the damping mechanism 4, and the steering head 1 are provided with a wiring channel 8 for power supply wires to pass through, so that external wiring can be connected to the lighting fixtures through the steering connector.

[0025] like Figures 3 to 6 As shown, the side wall of the connector 3 is provided with multiple through channels 31, and each channel 31 is movably installed with a retaining bead 5. The diameter of the retaining bead 5 is larger than the length of the channel 31, so that both ends of the retaining bead 5 can extend to the inner and outer walls of the connector 3. The top of the connector 3 is also provided with a pusher 6. The top end of the pusher 6 abuts against the damping mechanism 4, and the bottom end extends into the inner side from the top of the connector 3. The outer wall of the pusher 6 fits against the inner wall of the connector 3 and covers the inner port of the channel 31. The sleeve 2 is provided with a slot 21 for the retaining bead 5 to be inserted at the position of the channel 31 of the connector 3.

[0026] When assembling the steering joint, first insert the steering head 1 into the bottom of the sleeve 2 and pass it out through the limiting groove 24 at the top of the sleeve 2. Then, insert the damping mechanism 4 into the sleeve 2. Next, insert the connector 3, along with the retaining ball 5 and the pushing member 6, into the sleeve 2. During the process of inserting the connector 3 into the bottom of the sleeve 2, the top of the pushing member 6 abuts against the bottom of the spring 41 of the damping mechanism 4 and gradually moves into place as the connector 3 is installed. The pushing member 6 is pressed into the connector 3, and the side wall of the pushing member 6 pushes the retaining ball 5 from the side wall of the connector 3 into the retaining groove 21 on the inner wall of the sleeve 2, thereby achieving a secure installation between the connector 3 and the sleeve 2. The above assembly process is convenient to operate and effectively improves the assembly efficiency of the steering joint.

[0027] As a preferred embodiment of this utility model, the four evenly distributed locking beads 5 are arranged in a ring, ensuring even force distribution. The locking groove 21 is designed as an annular groove surrounding the inner wall of the sleeve 2 to facilitate the simultaneous insertion of multiple locking beads 5. The outer wall of the pushing member 6 has a conical surface 62 that mates with the locking beads 5. When the pushing member 6 is pushed downwards into the connector 3, the conical surface 62 contacts the locking beads 5 first. The locking beads 5 can then be more easily pushed out to the outside of the channel 31 to mate with the locking groove 21 under the oblique pressure of the conical surface 62. The bottom side wall of the pushing member 6 has a relief groove 61 for the locking beads 5 to be inserted. When the pushing member 6 and the connector 3 are pre-installed, the relief groove 61 and the through groove of the pushing member 6 are horizontally aligned, which is the initial installation state of the pushing member 6. At this time, part of the locking beads 5 is located in the channel 31, and part is located in the relief groove 61, allowing the pushing member 6 to be pre-installed and limited on the connector 3, making it easier to fix and assemble the connector 3 and the sleeve 2.

[0028] An axial guide structure is also provided between the connector 3 and the sleeve 2. The axial guide structure includes a protrusion arranged on the connector 3 and a guide groove 22 arranged axially on the inner wall of the sleeve 2. When the connector 3 is inserted from the bottom of the sleeve 2, the protrusion is engaged with the guide groove 22 and can slide along the guide groove 22. The cooperation between the protrusion and the guide groove 22 ensures that the connector 3 and the sleeve 2 have a unique installation position.

[0029] The protrusion and multiple retaining balls 5 are staggered in height, which is more conducive to the setting of the protrusion and allows for further design of the protrusion to achieve another function. For example, the protrusion is a ball 7 arranged above multiple retaining balls 5. The side wall of the connector 3 is also provided with a through channel 31 corresponding to the ball 7 for the ball 7 to be installed movably. The ball 7 always protrudes from the outer side wall of the connector 3 under the push of the pusher 6. The sleeve 2 is provided with a track 23 for the ball 7 to travel. The track 23 is not arranged 360° along the inner wall of the sleeve 2. Specifically, it can be arranged 180° or 270° along the inner wall of the sleeve 2, and the angle can be adjusted arbitrarily according to the situation, thereby limiting the circumferential rotation of the lamp.
