This utility model discloses a lockable sliding switch, comprising: an upper shell and a lower shell, the upper shell and the lower shell being connected to form a closed outer shell structure; a rotary lock seat, rotatably disposed within the upper shell and the lower shell; and a fixed lock seat, fixedly disposed within the upper shell and the lower shell, forming a relative rotational relationship with the rotary lock seat; the rotary lock seat is provided with a first locking plate, and the fixed lock seat is provided with a second locking plate; when the rotary lock seat is rotated to the locked position, the first locking plate and the second locking plate abut face to face, blocking the rotation of the rotary lock seat; the rotary lock seat is provided with a lock hole, and when the rotary lock seat is in the locked position, an external lock can be inserted into the lock hole and locked. This lockable sliding switch has the characteristics of double locking to prevent misoperation, stable gear switching, and reliable contact.

The utility model discloses a tunnel lighting device convenient to install and maintain, and relates to the technical field of lighting devices. The LED lamp comprises a shell, one side of the shell is fixedly connected with a mounting plate, one side of the shell is fixedly connected with a cooling fin, one side of the shell is fixedly connected with a controller, an LED lamp panel is arranged in the shell, a sealing plate assembly is arranged in the shell, the sealing plate assembly comprises a first magnet arranged in the shell, and a second magnet arranged in the shell is arranged in the shell. And the anti-falling plate is magnetically attracted to one side of the first magnet. According to the utility model, tool-free quick opening and closing of the shell are realized through the magnetic suction sealing plate assembly and the sliding design. During maintenance, only the closing plate needs to be pulled out, the transparent plate is pulled out, the LED lamp panel is directly exposed, and bolts do not need to be detached. Meanwhile, a limiting plate and a spring pressing mechanism are adopted in the fixing assembly, the LED lamp panel is rapidly positioned through a fixing groove, and unlocking and replacement can be achieved by pressing a fixing plate. No special tool is needed, and labor cost and operation complexity are reduced.

The utility model discloses a seat adjusting structure of a scenic spot scooter, and relates to the technical field of scenic spot scooter parts. The scooter comprises a scooter body, wherein the scooter body comprises a scooter bottom plate and a movable seat. An adjusting toothed plate is fixed to the middle front portion of the scooter bottom plate, and a gear is arranged in a movable base of the movable seat and meshed with the adjusting toothed plate. An adjusting groove is formed in the front end of the movable base and internally provided with an adjusting rod capable of being pressed downwards; an L-shaped adjusting clamping plate is arranged on the side of the gear, and a braking clamping head at one end of the L-shaped adjusting clamping plate can be clamped into a gear tooth groove and is kept in a locking state through a reset spring. When the adjusting rod is pressed down, the bottom end pushes the adjusting clamping plate to be separated from the gear, so that the movable seat slides back and forth; and after loosening, the reset spring drives the brake chuck to lock the gear again. The sliding seat can be unlocked only by pressing the adjusting rod downwards by a user, the sliding seat is automatically locked after being loosened, the handle does not need to be rotated repeatedly, the adjusting time is greatly shortened, and the vehicle turnover rate in the peak period of a scenic spot is remarkably increased.
