Description

Technical Field

[0001] The utility model belongs to the technical field of track light power box assembly structure, in particular to a track light power box and a track light with firmly clamped connection. Background Art

[0002] Currently, there are two main ways to install a track light power box. One method is to have snap-on springs on both sides of the power box housing. During installation, the snap-on springs squeeze into the track groove and engage with the snap-on grooves on the inner side of the track groove wall. However, these snap-on springs have a limited service life. If the user does not control the force when removing and installing again, it is easy to damage the snap-on springs, and the entire track light power box needs to be replaced.

[0003] Another method is to set a rotatable power connection post in the track light power box, and a swing arm connected to the power connection post and capable of driving the power connection post to rotate is provided at a position outside the power box shell and passes through the power box shell. A snap-on power connection piece is provided on the power connection post, and the swing arm can be rotated to drive the power connection post to drive the snap-on power connection piece to engage with the snap-on power connection slot on the inner side of the groove wall of the track groove, thereby realizing the functions of snap-on fixation and power connection; however, the rotation of the swing arm can easily cause accidental contact and loosening during the rotation process, causing the track light power box to fall out of the track groove. If a locking structure is provided, the structure of the track light power box will be more complicated, which will reduce the convenience of the rotation operation and the user experience on the basis of increasing the assembly and material costs.
