Embodiment Construction

[0018] Such as figure 1 and figure 2 As shown, it is a structural schematic diagram of an embodiment of a lamp with a limit pre-tightening structure in the present invention. The lamp main body 1 is fixedly connected with a fixing screw 10 for fixing the lamp main body 1 on the mounting plate 90. The mounting plate 90 can be The plate structure arranged on the vehicle or other devices has a mounting hole on it, and the fixing screw 10 passes through the mounting hole to fix the lamp main body 1 on the mounting plate.

[0019] In order to prevent the vibration transmitted from the mounting plate 90 from adversely affecting the main body 1 of the lamp, an elastic damping pad 40 is sleeved on the fixing screw 10. The elastic damping pad 40 has a ring groove 41 extending in the circumferential direction, and the ring groove 41 is stuck on the edge of the installation hole of the installation plate 90, which can realize the positioning of the elastic vibration damper 40 and facil...

Abstract

The invention relates to a luminaire with a limit pre-pressing structure, comprising a luminaire body, a fixed screw, an elastic anti-vibration pad and a stop collar; wherein the fixed screw is connected with the luminaire body and penetrates through the elastic anti-vibration pad; the stop collar is provided with a screwed hole matched with the fixed screw and a stop end face located at the tail end of the screwed hole; the stop collar is sleeved on the fixed screw and enables the elastic anti-vibration pad to be equipped with pre-pressing deformation; when pre-pressing deflection of the elastic anti-vibration pad reaches the preset value, the end face of the fixed screw is pressed against the stop end face. The luminaire of the invention is provided with a limit pre-pressing structure, so that when the luminaire is installed, appropriate compression deformation of the elastic anti-vibration pad can be ensured; meanwhile, pre-pressing can be carried out on the stop collar to prevent the stop collar from loosening in the process of use.

Description

technical field [0001] The invention relates to the field of lamps, more specifically, to a lamp with a limiting and pretightening structure. Background technique [0002] When the luminaire is installed and fixed, for the sake of anti-vibration, elastic members, such as rubber pads, are usually arranged between the luminaire and the fixed position to damp the vibration from the fixed position and prevent the luminaire from being damaged due to vibration or service life. become shorter. In order to obtain a better anti-vibration effect, the pre-compression amount of the elastic member is often limited, which requires the installation of fasteners to be limited. At the same time, in order to ensure that the elastic member does not loosen during vibration, pre-tightening treatment is also required. . The existing position-limiting and pre-tightening structure is complex in structure, involves many components, requires a large installation space, and is complicated to install...
