Description

Technical Field

[0001] The utility model belongs to the technical field of track lights, and particularly relates to a magnetic track light. Background Art

[0002] In the conventional technology, the magnetic power box of the magnetic track light is installed as follows: elastic hooks are formed on both sides of the magnetic power box through hollowing out. After the magnetic power box is installed on the power connection track, the elastic hooks are engaged with the engaging grooves on both sides of the power connection track, and then the magnetic power box is installed on the power connection track. However, only the elastic hooks are provided, and no shrinkage limiting part of the elastic hooks is provided. Therefore, the elastic hooks cannot avoid being retracted into the magnetic power box by external force, thereby causing the magnetic power box to fall off the power connection track, affecting the safety of users.

[0003] Furthermore, in the prior art, a switch assembly is provided between two elastic hooks in the magnetic power supply box, and limiting parts are provided on both sides of the switch assembly. The switch assembly is connected to the power supply box through elastic parts. In a normal state, the elastic parts enable the limiting parts on both sides of the switch assembly to abut against the inner sides of the two elastic hooks to achieve a locked state, and the switch assembly can prevent the two elastic hooks from retracting, thereby preventing the magnetic power supply box from being removed from the power supply track; in a compressed state of the elastic parts, the limiting parts on both sides of the switch assembly are offset from the inner sides of the two elastic hooks to achieve an unlocked state, and the switch assembly cannot prevent the two elastic hooks from retracting, thereby enabling the magnetic power supply box to be removed from the power supply track.

[0004] However, the above scheme can only realize the unlocking state of the switch assembly by changing the elastic member to a compressed state by continuous external force. The switch assembly cannot autonomously control itself to be stably in the unlocking state, and continuous control by external force is required to keep the switch assembly in the unlocking state. As a result, the user cannot simultaneously control the switch assemblies at both ends of the longer magnetic power box to be in the unlocking state, thereby reducing the user's experience.

[0035] In the conventional technology, the magnetic power box of the magnetic track light is installed as follows: elastic hooks are formed on both sides of the magnetic power box through hollowing out. After the magnetic power box is installed on the power connection track, the elastic hooks are engaged with the engaging grooves on both sides of the power connection track, and then the magnetic power box is installed on the power connection track. However, only the elastic hooks are provided, and no shrinkage limiting part of the elastic hooks is provided. Therefore, the elastic hooks cannot avoid being retracted into the magnetic power box by external force, thereby causing the magnetic power box to fall off the power connection track, affecting the safety of users.

[0036] Furthermore, in the prior art, a switch assembly is provided between two elastic hooks in the magnetic power supply box, and limiting parts are provided on both sides of the switch assembly. The switch assembly is connected to the power supply box through elastic parts.

The switch assembly cannot autonomously control itself to be stably in the unlocking state, and continuous control by external force is required to keep the switch assembly in the unlocking state. As a result, the user cannot simultaneously control the switch assemblies at both ends of the longer magnetic power box to be in the unlocking state, thereby reducing the user's experience.

The magnetic track light according to claim 6, characterized in that: The magnetic power supply box further comprises: a first power connection spring sheet and a second power connection spring sheet, wherein one end of the first power connection spring sheet is fixed to the top surface of the control circuit board, and the other end of the first power connection spring sheet extends outward through the power supply box cover, and one end of the second power connection spring sheet is fixed to the top surface of the control circuit board, and the other end of the second power connection spring sheet extends outward through the side surface of the power supply box shell; The inner wall of the power connection track is provided with receiving grooves along its length direction, the first part of the receiving groove is located on the top surface of the inner wall of the power connection track, the second part of the receiving groove is located on the side of the inner wall of the power connection track, an insulator is provided in the receiving groove, the insulator is provided with a first conductor at the position of the first part, and the insulator is provided with a second conductor at the position of the second part; After the magnetic power supply box is installed in the power connection track, the first power connection spring piece abuts against the first conductor and is electrically connected to the first conductor, and the second power connection spring piece abuts against the second conductor and is electrically connected to the second conductor.

8. The magnetic track light according to claim 7, characterized in that: A magnetic track groove is formed on the top surface of the inner wall of the power connection track between the two receiving grooves, and a magnetic member is arranged in the magnetic track groove; A magnet is provided on the top surface of the power box cover, and the magnet and the magnetic member cooperate with each other to magnetically fix the magnetic power box and the power connection track.

9. The magnetic track light according to claim 1, characterized in that: Both sides of the top of the power connection track are provided with mounting grooves along the length direction thereof, and the mounting grooves are used for fixing the power connection track.

10. The magnetic track light according to claim 1, characterized in that: The magnetic power supply box further comprises: a lamp fixing column and a fixing bolt installed on the housing of the power supply box; One end of the lamp fixing column is provided with an abutting convex edge, and the other end of the lamp fixing column passes through the bottom of the power box shell from the inside of the power box shell. After the fixing bolt is screwed with the other end of the lamp fixing column, the abutting convex edge presses against the inner wall of the power box shell, so that the lamp fixing column is fixed to the bottom of the power box shell; The fixing bolt extends outward to form a first limiting protrusion, and a second limiting protrusion is provided on the outer side of the bottom of the power box shell. The first limiting protrusion abuts against the second limiting protrusion, thereby limiting the rotation angle of the fixing bolt.
