According to the rubber ring detection device, rubber rings of different sizes can be fixed through the arranged fixing assembly, the opening and closing degree of the clamping rods can be adjusted at will only by releasing limiting of the limiting rods on the connecting blocks, operation is easy and convenient, the working efficiency is improved, meanwhile, it can be guaranteed that the rubber rings are always overlapped with the light-transmitting plate, and the detection effect is guaranteed.

The invention relates to the technical field of electronic equipment, and provides a hinge assembly and mobile equipment. The hinge assembly comprises a main support, a rotating assembly and a fixing piece, one end of the rotating assembly is rotationally connected with the main support, the other end of the rotating assembly is rotationally connected with the fixing piece, the rotating assembly comprises a first swing arm, the first swing arm comprises a first main swing arm and a first auxiliary swing arm which are rotationally connected, and the rotating assembly further comprises a second swing arm; the second swing arm and the first swing arm are arranged in a spaced mode, the second swing arm and the first auxiliary swing arm are connected through a connecting piece, and the rotating axis of the first auxiliary swing arm and the rotating axis of the second swing arm on the connecting piece are parallel and do not coincide. According to the hinge assembly, when the first swing arm rotates by the same angle as that of a traditional single virtual swing arm, the needed space in the thickness direction is small, then the thickness of the hinge assembly can be reduced, the rotation angle does not need to be increased, the coincidence amount of the first swing arm and the hinge support can be guaranteed, and the first swing arm is prevented from being disengaged.

The application discloses a picture motion compensation method and system in multi-screen combination and a storage medium, and relates to the field of picture display. The method comprises the following steps: acquiring first picture information and second picture information of different screen blocks respectively; determining distance direction offset and direction offset of picture pixel values of the first picture information and the second picture information based on a cross-correlation algorithm; correcting the distance direction offset and the direction offset until absolute values of the distance direction offset and the direction offset are within a preset threshold; calculating picture display frequencies of the first picture information and the second picture information, adjusting time of a target splicing boundary of the first picture information and the second picture information based on the picture display frequencies; and multiplying a correction result of the distance direction offset and the direction offset and a time adjustment result of the target splicing boundary to obtain an offset compensation amount, and realizing picture motion compensation in multi-screen combination by using the offset compensation amount. The application better solves the problem of misalignment at a screen splicing position.

According to the automatic acquisition equipment for the three-dimensional real scene of the rock core, the rock core is placed on the rotatable roller of the rotating seat, the camera on the camera frame of the U-shaped frame structure can cover the cylindrical surface and the cross section of the rock core, 360-degree all-dimensional dead-corner-free shooting can be carried out by automatically rotating the rock core through the roller, the overlapping degree and the angle of rock core photos required by modeling are ensured, and the modeling efficiency is improved. Importing the photo into computer three-dimensional live-action modeling software to carry out core three-dimensional live-action modeling; in addition, the multiple rollers arranged in parallel enable the equipment to be capable of containing rock cores with different diameters. The automatic acquisition equipment can quickly and completely acquire all-dimensional dead-angle-free multi-view pictures of the cylindrical surface and the section of a real rock core at one time, so that the picture acquisition time and the subsequent rock core three-dimensional live-action modeling time are greatly shortened, and the rock core shooting and modeling efficiency and the success rate are improved; the obtained three-dimensional real scene model reflects the real texture and geometric morphology of the rock core, and the engineering rock core management level and the digital level are greatly improved.

The invention provides a composite infiltrated layer as well as a preparation method and application thereof. The preparation method comprises the following steps: carrying out zinc impregnation treatment on a steel matrix by utilizing a zinc impregnation agent; and the steel matrix subjected to zinc impregnation treatment is subjected to swing laser melting treatment, and the abrasion-resistant and corrosion-resistant composite infiltrated layer is obtained. According to the method, laser melting with different swing tracks is carried out, so that the molten pool forms a vortex along the swing path of the laser, a more stable and uniform zincizing layer is formed on the surface of the zincizing steel and iron material, grains are further refined after remelting, and the hardness and wear resistance of the surface of the steel and iron material are improved.
