The invention provides display equipment with a camera, comprising a shell body, the camera and a foot bracket, wherein the camera is fixed on the shell body; the shell body is internally provided with a synchronous transmission component; the synchronous transmission component comprises a camera rotation module, a foot bracket rotation module and a transmission device; the camera rotation module is connected with the camera, and is capable of enabling the camera to rotate; the foot bracket rotation module is fixedly arranged on a display screen, and is capable of enabling the display screen to rotate relative to the foot bracket; the transmission device is connected between the camera rotation module and the foot bracket rotation module, and is used for realizing the linkage between the camera rotation module and the foot bracket rotation module; the foot bracket rotation module drives the camera rotation module to rotate through the transmission device when the shell body rotates relative to the foot bracket, so that an angle between the camera and the shell body is adjusted. According to the display equipment with the camera provided by the invention, a user can adjust the angle of the camera synchronously in the process of adjusting the display angle of the display screen, so that the user conveniently uses the display equipment with the camera.

The present invention relates to the technical field of medical devices and particularly to a hovering arm and a therapeutic instrument. The hovering arm comprises two hovering supports and hovering mechanisms, one ends of the hovering supports are rotationally connected with first movable parts, the other ends of the hovering supports are rotationally connected with second movable parts, the twohovering supports are arranged in parallel, each hovering mechanism comprises a hovering spring, two ends of the hovering spring are connected with the first movable part and the second movable part respectively, the hovering mechanism also comprises a hovering sleeve, the hovering spring is arranged in the hovering sleeve, the hovering sleeve comprises an inner sleeve and an outer sleeve which are connected in a sleeved mode, one end of the inner sleeve is rotationally connected with the first movable part, an outer wall of the other end of the inner sleeve abuts against an inner wall of theouter sleeve, the inner sleeve and the outer sleeve form a friction pair, and one end, away from the inner sleeve, of the outer sleeve is rotationally connected with the hovering support. The therapeutic instrument comprises the hovering arm. By adopting the scheme, a technical problem that angles and heights of a treatment lamp cannot be kept due to long-time use of tension springs in the prior art can be solved.

The invention belongs to the technical field of electric power facilities, and is specifically an alternate adsorption cable conveying equipment, which includes a bottom plate, a support seat, a support seat, a column, a No. 2 rotating shaft, a No. 1 flange and a conveying device; The rotation of the No. 2 motor drives the No. 2 pulley to rotate, and then drives the No. 3 shaft to rotate, and then drives the No. 2 pulley to rotate. At the same time, the No. 1 synchronous pulley drives the No. During the rotation of the number wheel, the No. 1 suction shaft and the No. 2 suction shaft open ends are pumping through the trachea all the time, and then the air in the ventilation slot is sucked out, and the gas in the airtight cavity formed by the semicircular slot and the cable is pumped out. Extraction, so that the semicircular groove is adsorbed on the surface of the cable, and then when the first wheel and the second wheel rotate, the cable is absorbed through the semicircular groove, and then the cable is dragged to move, which facilitates the transportation of the cable and reduces the labor of the workers. strength.

The invention discloses an automatic goods unloading device capable of extending. The automatic goods unloading device capable of extending comprises an unloading supporting platform, a platform extending device, night reflectors, side shielding boards, base supporting vertical rods, hydraulic supporting rods, supporting stand columns, base supporting transverse rods, a middle reinforcement rod, alimiting connection transverse rod and an extending flat short board, wherein the front portion of the unloading supporting platform is connected with the extending flat short board; the lower end ofthe rear side of the unloading supporting platform is connected with the platform extending device; a control panel is arranged on the platform extending device and provided with a single-chip microcomputer; and the control panel is provided with a display screen, a distance sensor, a height sensor, a power switch and a positive and negative rotation switch. Through the platform extending device,when goods need to be unloaded at high places, the length of the unloading platform of the device can be extended, the device can unload the goods more effectively, and accordingly the unloading safety of the goods is ensured, the unloading speed of the device is greatly increased, and practicability is high.

The invention discloses a height adjustment system, which includes a height adjustment motor, a connecting rod assembly, a self-locking assembly and an overturning assembly. After the height adjustment motor drives the connecting rod assembly to move, the connecting rod assembly drives the overturning assembly Flip up and down, the self-locking assembly is installed on the connecting rod assembly, when the height adjustment motor drives the connecting rod assembly, the self-locking assembly unlocks the connecting rod assembly, so that the connecting rod assembly can drive The overturning component is turned upside down; when the overturning component is pushed down by the seat, the overturning component drives the connecting rod component, and the connecting rod component drives the self-locking component to lock with the connecting rod component. The height adjustment system and the seat fixing device in the invention can accurately adjust the seat, facilitate operation, and avoid scratches and deformation of the seat frame.
