This utility model discloses a multifunctional detector, applied in the field of detection instruments, which solves the technical problem of inconvenience in the use of existing multifunctional moisture detectors. The key technical points are: it includes a device body comprising a grip and a detection part; the grip contains a power supply block; the detection part contains a central processing block, a display block, a button block, and a detection component; the detection component includes a sensing probe located at the end of the detection part and a sensing detection cavity block rotatably connected to the end of the detection part; the detection part has a slide rail groove, within which a rotating slider is slidably connected; the sensing detection cavity block is rotatably connected to the rotating slider; the end of the detection part has a stepped ring edge around its perimeter; the inner wall of the sensing detection cavity block has a stepped ring groove that engages with the stepped ring edge; and the side of the device body also has an elastic band, effectively improving the ease and stability of use.

The RGB image acquisition unit (30) acquires an RGB image of the object. The ranging image acquisition unit (32) acquires a ranging image of the object along the same optical axis. The RGB image motion detection unit (40) detects movement in the RGB image for each pixel by taking the difference between the current frame and the previous frame. The ranging image motion detection unit (42) detects movement in the ranging image for each pixel by taking the difference between the current frame and the previous frame. The interference determination unit (50) determines whether there is infrared interference during the acquisition of the ranging image for each pixel based on whether there is movement in the RGB image and whether there is movement in the ranging image.

The utility model provides a kind of key light guide cover and light guide key assembly, key light guide cover includes base body, pressure-bearing body and support body, support body is fixedly connected between base body and pressure-bearing body, and the relative height between the front of pressure-bearing body and the front of base body is greater than zero, the front of pressure-bearing body includes light transmission area and backlight area, and the thickness of backlight area is greater than the thickness of light transmission area.Light guide key assembly includes aforementioned key light guide cover and light source.The utility model discloses technical scheme, because the thickness of backlight area is greater than the thickness of light transmission area, the light propagation path of light source generated light is shorter in light transmission area, and the intensity and brightness loss of light are lower, so as to enhance light transmission area brightness effect, and the light propagation path of light source generated light is longer in backlight area, so that the intensity and brightness of reflected light are weakened, the interference effect of reflected light and light propagation in light transmission area is reduced, light is reduced, so that user observes correct character or pattern from light transmission area, and misoperation to key is avoided.

The utility model discloses a kind of torsional center of mass stick for seat safety belt fixing point test, it is related to automobile seat safety belt fixing point test technical field, including rubber stick body, the metal stick body connected with rubber stick body both ends, metal stick body is equipped with the fixed block for connecting seat, the connecting hole for connecting loading equipment;A kind of torsional center of mass stick for seat safety belt fixing point test of the utility model, precise transmission of test load and backrest deformation self-adaptation are realized by metal and rubber composite structure, backrest deformation followability is strong, compared with rigid center of mass stick, the interference effect of rigid center of mass stick to seat structure is eliminated, prevent center of mass stick from falling off in test process, improve test efficiency and accuracy.

The application belongs to the technical field of adhesive curing forming of helicopter composite components, and particularly relates to a large slenderness ratio composite component adhesive tooling suitable for curing deformation and a use method. A modular design structure form is adopted, a bottom frame is used as a main module to provide an installation platform, an upper module is designed on the installation platform, the upper module comprises a sliding table and a positioner and a clamping plate directly contacting the product, and the product is fixed on the sliding table after the positioner and the clamping plate are set. A bidirectional sliding platform is designed between the upper module and the main module to provide bidirectional sliding functions in the length direction and the width direction. When the main module is affected by temperature to generate size changes, the internal structure of the adhesive tooling can be self-adaptively adjusted to deform, and the upper module and the positioner will not slide, so that the generation of curing stress is avoided, and the deformation caused by the inconsistent thermal expansion coefficients is effectively controlled.
