3results about How to "Add support function" patented technology

This utility model discloses a tablet computer protective case, including a housing for accommodating the tablet computer and a support frame for supporting the housing. The support frame includes a first support frame and a second support frame. The first support frame is hinged to the back of the housing in a flip-out manner, and the second support frame is hinged to the middle of the first support frame in a flip-out manner relative to the first support frame. A clearance space is provided on the first support frame for the second support frame to flip back to its original position, and the second support frame, after flipping back to its original position, is located within the clearance space. Therefore, by utilizing the multiple flip angles and combinations of the first and second support frames, multiple angle supports for the housing can be achieved, enabling the protective case to provide writing and drawing support and height support for the tablet computer, meeting various user needs and improving the user experience.

The invention discloses a high-performance aluminum alloy friction stir welding seam quality detection device, and relates to the technical field of welding quality detection.The high-performance aluminum alloy friction stir welding seam quality detection device comprises a welding seam detection mechanism, a displacement mechanism is arranged at the top of the welding seam detection mechanism, a conveying mechanism is arranged at the bottom of the displacement mechanism, and clamping turnover mechanisms are arranged on the two sides of the conveying mechanism; the weld joint detection mechanism comprises a detector, visual probes are fixedly connected to the two sides of the detector, and an ultrasonic array probe is fixedly installed at the bottom of the detector. Through multi-direction and multi-angle adjustment, the detection angle is increased, the detection range is further increased, the detection effect is guaranteed, the detection efficiency is effectively improved, the overturning function is achieved through control of the overturning motor, a clamped object can be rapidly adjusted, and the detection efficiency is improved. And the multi-surface gap detection function can be realized.

The application discloses a low-temperature liquid ammonia pump inducer assembly, which comprises an inducer, a sleeve and a bearing seat sleeved on the inducer, the inducer is fixed with the sleeve, the bearing seat is fixed on a pump shell, and the bearing seat and the sleeve form a sliding friction pair; a threaded groove and an annular collecting groove are arranged on the outer circle of the sleeve, the front end of the threaded groove is communicated with the annular collecting groove, the rear end of the threaded groove is arranged to the rear end surface of the sleeve, and the rotating direction of the threaded groove is opposite to the working rotating direction of the inducer; the outer circle of the bearing seat is uniformly distributed with backflow holes, the backflow holes penetrate through the bearing seat and are located at the front end of the inducer, the outer circle of the bearing seat is provided with a backflow groove, the front end of the backflow groove is communicated with the corresponding backflow hole, and the rear end of the backflow groove is arranged to the rear end surface of the bearing seat. The application has the characteristics of compact structure, high reliability, high cavitation resistance, support function and dynamic sealing effect, improved cavitation resistance, improved hydraulic efficiency of the pump, enhanced operation stability and prolonged service life.
