The utility model discloses an automobile steering lamp testing fixture which comprises a detection workbench, a supporting plate is fixedly arranged at the upper end of the detection workbench, a protection mechanism is arranged on the upper side of the supporting plate, a clamping mechanism is arranged on the front side of the protection mechanism, and the protection mechanism comprises a mounting plate fixedly arranged at the upper end of the supporting plate. An air cylinder is fixedly installed at the rear end of the installation plate, a first rack is fixedly connected to one side of the air cylinder, a fluted disc is movably arranged on the lower side of the first rack, and protection frames are fixedly arranged at the positions, close to the two sides, of the front end of the supporting plate. According to the automobile steering lamp testing fixture of the utility model, when the air cylinder is contracted, the group of fixing plates at the front side drive the protective net to move forward along with the two groups of sliding blocks, so that the protective net can be opened, automobile steering lamp products can be protected, and the steering lamp products can be prevented from being damaged due to direct falling when the clamping mechanism is instable in clamping.

This invention relates to the field of throttle valve technology and discloses an ultra-high pressure zero-leakage throttle valve based on pressure rating. The valve includes a main body shell, with a sealing tube mounted on the top outer wall of the main body shell. A rotating handle is located at the top of the sealing tube. Two sets of semi-circular sealing plates are rotatably connected to one end of a limiting ring via U-shaped plates. The other end of the limiting ring is slidably connected to a support rail. When the two sets of semi-circular sealing plates move, the guiding effect of the support rail and the limiting ring causes their opposite ends to simultaneously converge towards the center end of the support rail. Simultaneously, the pressure of the flowing liquid applies pressure to the center end of the support rail, thereby reducing the liquid pressure on the rotating shaft driven by the rotating handle, which in turn drives the lead screw. This reduces the force required to open the device, facilitating easier device operation.
