The invention discloses a supporting frame for computer hardware teaching demonstration, and relates to the field of teaching supporting frames, the supporting frame comprises a supporting seat and a supporting cylinder arranged in the supporting seat, the supporting cylinder is slidably provided with a bearing box, the bearing box is internally provided with an upper layer cavity and a lower layer cavity, and the upper layer cavity is internally provided with a placing box; a placing plate is arranged in the lower-layer cavity, a control assembly is arranged in the supporting cylinder, a handle is fixedly arranged on the supporting cylinder, a first unfolding assembly is arranged in the handle and the upper-layer cavity, and a second unfolding assembly is arranged in the lower-layer cavity. During demonstration, the bearing box ascends, the placement box and the placement plate are unfolded to form a three-dimensional display space, the space utilization rate is maximized, the placement plate is in an inclined state, students in the back row can easily and clearly see the whole view and layout of the plate surface, the problem that the sight is blocked during static flat placement is solved, and the teaching efficiency of teachers is improved.

The utility model relates to the technical field of mobile phone accessories, and discloses a ring card bag support which comprises a silica gel shell. The plastic plate is arranged in the silica gel shell, and at least one magnet is arranged in the plastic plate; the card bag is fixedly connected to the outer wall of the silica gel shell; the arched ring and the card bag are integrally arranged; a groove for accommodating the magnet is formed in the plastic plate, and the magnet comprises an annular magnet and a tail magnet which are arranged in the groove; the outer side of the plastic plate is covered with a protection piece used for fixing the annular magnet and the tail magnet. And the protective sheet is made of a PVC (Polyvinyl Chloride) material. According to the utility model, the arched ring has the functions of a ring and a support, and can prevent slipping and support film watching. The built-in magnet realizes a magnetic attraction function, and is convenient for vehicle-mounted use. The integrated design integrates multiple functions, the burden caused by the fact that a user needs to be equipped with various accessories is avoided, and great convenience and market competitiveness are achieved.

The application discloses an electric vehicle garage entrance and exit frame with scratch-proof protection structure, and belongs to the technical field of electric vehicle parking. The electric vehicle garage entrance and exit frame comprises a frame main beam, a parking mechanism arranged in the frame main beam and used for separately separating a plurality of electric vehicles, and a wind guide mechanism arranged on both sides of the frame main beam. The parking mechanism comprises a fixed plate fixed to the inner wall of the frame main beam, the fixed plate is fixed in the frame main beam through a plurality of bolts, the outer wall of the fixed plate is fixedly connected with a plurality of limiting frames, the plurality of fixed plates are equidistantly arranged, and the fixed plates are used for clamping electric vehicle front wheels. The parking mechanism is adopted, the fixed plate, the bolt and the limiting frame are matched with each other, a plurality of electric vehicles can be separately parked, the mutual scratching of the electric vehicles due to the small distance between the electric vehicles can be effectively prevented, and the plurality of electric vehicles have a certain distance, so that the convenience of subsequent users in moving the electric vehicles in or out is improved.
