Description

Technical Field

[0001] This utility model relates to the field of lamp holder technology, specifically to a detachable and adjustable lamp holder. Background Technology

[0002] Track lights are lighting fixtures installed on a track, allowing for free adjustment of the illumination angle. They are commonly used in locations requiring focused lighting and are popular due to their ease of installation and flexible adjustment. The track light's track contains a voltage input, typically 220V AC. The track light's connector has a rotatable conductive copper plate that contacts the conductive metal strip inside the track to supply power.

[0003] Existing track lights can only move their lamp heads horizontally along the track, allowing for horizontal adjustment, but they cannot be adjusted vertically according to usage, which limits their usability. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a detachable and adjustable lamp head, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable and adjustable lamp head, including a lamp head, with two fixing plates fixed to the rear end of the lamp head, a connecting seat rotatably connected inside the fixing plates, an external threaded cylinder rotatably connected to the rear end of the connecting seat, an adjusting rod provided behind the connecting seat, the adjusting rod including a fixed tube, a movable tube slidably connected inside the fixed tube, an internal threaded cylinder fixed to the front end of the movable tube, the internal threaded cylinder and the external threaded cylinder being screwed together, and a mobile power supply box fixed to the rear end of the fixed tube;

[0006] The power bank box has a fixed track that slides inside. The outer wall of the moving tube is integrally formed with a groove. A support plate is provided inside the groove. A power cord is fixed inside the support plate. The left end of the power cord is fixedly connected to the power bank box. The other end of the power cord passes through the moving tube, the internal threaded cylinder and the connecting seat, and is fixedly connected to the lamp head.

[0007] Preferably, the fixing plate has two fastening screws inside, and the fastening screws are screwed to the connecting seat.

[0008] Preferably, a lever is fixed to the side of the fastening screw away from the fixing plate.

[0009] Preferably, a rotating plate is fixed to the outer wall of the externally threaded cylinder.

[0010] Preferably, the fixed tube is provided with a positioning mechanism inside, the positioning mechanism including a fixed rack, the fixed rack being fixed inside the fixed tube, the movable tube having a receiving hole inside, a plurality of springs being fixed inside the receiving hole, and a movable rack being fixed to the other end of the springs, the movable rack and the fixed rack being meshed and connected.

[0011] Preferably, a fixed cylinder is fixed to the outer wall of the internally threaded cylinder, and a pressure block is slidably connected inside the fixed cylinder. A round block is fixed to the left end of the pressure block, and a pull rope is fixed to the left side of the moving rack. The other end of the pull rope passes through the moving tube, the internally threaded cylinder, the fixed cylinder, and the round block, and is fixedly connected to the inner wall of the fixed cylinder.

[0012] Beneficial effects

[0013] This utility model provides a detachable and adjustable lamp holder. Compared with the prior art, it has the following advantages:

[0014] 1. The detachable and adjustable lamp head is equipped with an adjustment rod. Pulling the lamp head moves the moving tube, which lowers the lamp head. The moving tube lowers along with the power cord, and the power cord does not affect the movement of the moving tube and the lamp head. The lamp head can be adjusted up and down.

[0015] 2. The detachable and adjustable lamp head is equipped with a positioning mechanism. A spring pushes the moving rack to move, and the moving rack and the fixed rack mesh. In this way, the fixed rack restricts the downward movement of the moving rack, and the moving rack restricts the movement of the moving tube and the lamp head, thus fixing the height of the lamp head.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a detachable and adjustable lamp head, including a lamp head 1. Two fixing plates 5 are fixed to the rear end of the lamp head 1. A connecting seat 7 is rotatably connected inside the fixing plate 5. An external threaded cylinder 12 is rotatably connected to the rear end of the connecting seat 7. An adjusting rod 2 is provided behind the connecting seat 7. The adjusting rod 2 includes a fixing tube 10. A movable tube 9 is slidably connected inside the fixing tube 10. An internal threaded cylinder 8 is fixed to the front end of the movable tube 9. The internal threaded cylinder 8 and the external threaded cylinder 12 are screwed together. A mobile power supply box 3 is fixed to the rear end of the fixing tube 10. A fixed rail 4 is slidably connected inside the mobile power supply box 3. The outer wall of the movable tube 9 is integrally formed. The groove 23 has a support plate 14 inside, and a power cord 16 is fixed inside the support plate 14. The left end of the power cord 16 is fixedly connected to the mobile power supply box 3, and the other end of the power cord 16 passes through the moving tube 9, the internal threaded cylinder 8 and the connecting seat 7, and is fixedly connected to the lamp head 1. This allows the height of the lamp head 1 to be adjusted. The fixing plate 5 has two fastening screws 6 inside, which are screwed to the connecting seat 7. The fastening screws 6 clamp the fixing plate 5 and the connecting seat 7, allowing the lamp head 1 to rotate. A lever is fixed on the side of the fastening screw 6 away from the fixing plate 5, which facilitates the rotation of the fastening screw 6. A rotating plate 13 is fixed on the outer wall of the external threaded cylinder 12, which facilitates the rotation of the external threaded cylinder 12.

[0025] Furthermore, the fixed tube 10 is equipped with a positioning mechanism 11, which includes a fixed rack 24 fixed inside the fixed tube 10. The movable tube 9 has a receiving hole 22 inside, and multiple springs 20 are fixed inside the receiving hole 22. The other end of the spring 20 is fixed with a movable rack 21. The movable rack 21 and the fixed rack 24 are meshed and connected, which can position the movable tube 9 and the lamp head 1. The outer wall of the internal threaded cylinder 8 is fixed with a fixed cylinder 17. The inside of the fixed cylinder 17 is slidably connected with a pressure block 18. The left end of the pressure block 18 is fixed with a round block 19. The left side of the movable rack 21 is fixed with a pull rope 15. The other end of the pull rope 15 passes through the movable tube 9, the internal threaded cylinder 8, the fixed cylinder 17 and the round block 19, and is fixedly connected to the inner wall of the fixed cylinder 17, which can control the movement of the movable rack 21.

[0026] During operation, press the pressure block 18. The pressure block 18 moves the round block 19, which pulls the pull rope 15. The pull rope 15 pulls the moving rack 21, which separates from the fixed rack 24. Then, pull the moving tube 9, which moves the lamp head 1. This allows the lamp head 1 to descend, adjusting its height. The descending moving tube 9 will also bring the power cord 16 down. The power cord 16 will not affect the movement of the moving tube 9 and the lamp head 1. After the height of the lamp head 1 is adjusted, release the pressure block 18. The spring 20 then pushes the moving rack 21 to move. The moving rack 21 engages with the fixed rack 24, thus the fixed rack 24 restricts the downward movement of the moving rack 21. The moving rack 21 restricts the movement of the moving tube 9 and the lamp head 1, fixing the height of the lamp head 1.
