The application discloses a kind of intelligent walking aids, it is related to walking aid technical field, including vehicle body and the drive car and universal wheel of vehicle body bottom installation, vehicle body is connected with seat mechanism, driving assembly is installed on vehicle body, and support mechanism is connected on vehicle body;The application is a kind of intelligent walking aid, when user needs to rest or physical strength is not supported hand, electric push rod will push seat plate to rotate upwards, so as to facilitate user to sit down and rest, elastic belt has elasticity, play certain buffering effect, can avoid user physical strength to fall down when not supported, support rod will be along fixed column by chute sliding, to drive support rod to stretch out outward, the universal wheel of support rod bottom end will be contacted with ground, to play certain supporting effect, avoid when user sits, vehicle body is tilted back, so more stable, when user appears incontinence, can be actuated actuator block to the side frame of vehicle body is shielded, to protect the self-esteem of user.

The utility model discloses an electrical equipment maintenance device which comprises a maintenance platform, a rotatable supporting platform is arranged at the top of the maintenance platform, a circular groove matched with the supporting platform is formed in the top of the maintenance platform, the bottom of the supporting platform is fixedly connected with a rotating column, the rotating column is rotationally connected with the maintenance platform, and the supporting platform is fixedly connected with the rotating column. And the bottom of the rotating column is fixedly connected with a rotating disc, the rear side of the top of the maintenance table is fixedly connected with a detection panel, and the top of the inner cavity of the maintenance table is fixedly connected with a fixed shell. The maintenance platform and the supporting platform are used in cooperation, electrical equipment is placed, meanwhile, the angle and the position of the electrical equipment are changed under the cooperation of the rotating column and the rotating disc, meanwhile, the adjusted angle and the adjusted position are limited and locked under the cooperation of the locking assembly, and the maintenance platform is convenient to use. Therefore, the maintenance position of the electrical equipment can be adjusted conveniently, and wiring and maintenance of a user are facilitated.

This invention belongs to the field of medical device technology, and specifically relates to a three-stage dilatation balloon for preventing contrast agent leakage. Addressing the problem that existing three-stage dilatation balloons rupture when the operating pressure exceeds the rated burst pressure, resulting in the instantaneous leakage of high-pressure contrast agent into the patient's body, leading to embolism or tissue damage, the following solution is proposed: an outer balloon body, an inner balloon body, a mesh reinforcement layer, a sheath, and a decompression balloon. The inner balloon body is located inside the outer balloon body, and the ultimate expansion diameter of the outer balloon body is larger than that of the inner balloon body. Both are made of different polymer materials, ensuring that the outer balloon body remains intact and forms a leakage-proof barrier when the inner balloon body ruptures. A mesh reinforcement layer is sandwiched between the inner and outer balloon bodies, and the intersection points of the mesh reinforcement layer are discretely connected to the outer wall of the inner balloon body via micro-anchors. This invention achieves automatic emergency storage and manual aspiration and removal of the contrast agent after balloon rupture, solving the safety problem of contrast agent leakage after overpressure rupture of existing balloons.

The utility model discloses a kind of sorting unloading devices for peeling machine, including device base, the top surface of device base is provided with three chutes, the top of device base is equipped with fixed plate and moving plate, fixed plate is vertically fixed on the top surface of device base and is located in one end of chute, rotating sleeve pipe is rotatably connected on the opposite side of fixed plate and moving plate, copper wire winding roller is connected between fixed plate and moving plate located in middle portion.The utility model device is installed in the discharge port of peeling machine, after cable peeling, cable skin is wound on cable skin winding roller, copper wire is wound on copper wire winding roller, after starting motor, three winding rollers are driven to rotate, copper wire and cable skin after peeling can be collected respectively, during collecting process, cable is also pulled to a certain extent, peeling speed is accelerated, after collecting is completed, winding roller can be disassembled, processing efficiency is improved, the problem that copper wire and cable skin after peeling can be avoided to occur mutual winding.

The invention relates to the field of humanoid robots, and discloses a humanoid robot waist flexible structure which comprises a base and a first harmonic motor movably connected to the upper portion of the base through a first motor support, and the top of the first harmonic motor is movably connected with a second harmonic motor through a second motor support. The top of the second harmonic motor is movably connected with a third harmonic motor through a third motor support, the exterior of the base is fixedly connected with a lower shell, the top of the lower shell is fixedly connected with an upper shell through a shell connecting piece, and the top of the base is rotationally connected with an air cylinder through a connecting base; the output end of the air cylinder is rotationally connected with the third motor support through a rotating shaft. The waist function of the humanoid robot is achieved through deformation of the waist material and movement of the three large harmonic motors in the up-down, left-right and front-back directions, so that the waist of the humanoid robot does various actions like a person and is connected with one another and does not interfere with one another, and the flexibility of waist movement is improved.
