The invention discloses a rubber-tired road roller safety protection device for preventing people from being hit or rolled over. The safety protection device comprises protective frames used for insulating people from road roller rubber-tired wheels. The protective frames are arranged on the front sides of the road roller front rubber-tired wheels and / or the rear sides of the road roller rear rubber-tired wheels, and connected with a road roller body. The safety protection device can effectively insulate the people from the road roller rubber-tired wheels in the running process of the road roller, it is guaranteed that the pavement operating personnel is not injured by the road roller rubber-tired wheels, and the rubber-tired road roller safety protection device is simple in structure, convenient to use, high in practical value, and convenient to apply and popularize.

The invention discloses a rolling-free isolating device for a wheel. The rolling-free isolating device for the wheel is used for stopping direct contact between an object and a wheel in the wheel advancing direction by being arranged in front of, behind or on the side of the wheel and is used for automatically realizing continuous stopping or opening according to a stress condition; and that is tosay that the rolling-free isolating device is kept in a stopping state when the stress is less than a set value and the rolling-free isolating device is opened for the wheel to pass when the stress is larger than the set value; therefore, people or other objects needing to be stopped can be reliably and effectively prevented from getting under the wheel to suffer rolling injury; and for objects which can pass steps and so on, the rolling-free isolating device can be opened for the wheel to pass without hindering the normal running of a vehicle.

The invention discloses an anti-pinch ticket evader injection access control card swiping device with a stretching and contracting function. The anti-pinch ticket evader injection access control cardswiping device structurally comprises a device body, a display screen, a cover plate, a card swiping area and a stretching and contracting clamping plate mechanism. The anti-pinch ticket evader injection access control card swiping device has the beneficial effects that an arranged clamping preventing structure is used so that when the leg of a ticket evading gate passing person is pinched, an anti-pinch plate receives the extruding force of the leg of the gate passing person so as to move inwards, a certain retreating time is provided for the gate passing person, the phenomenon that the leg of the gate passing person is subjected to mechanical stretching and contracting of the equipment and is seriously extruded and injured is avoided, and the personnel safety of the gate passing pinchedperson is improved; and due to the cooperation of a self air blowing structure and a tight pinch preventing structure, when the ticket evading gate passing person is pinched to retreat backwards and then directly moves forwards at the same time, under the repulsive effect between a soft magnetic piece and a magnetic plate embedded in the inner wall of the air bag, the air bag is in a shriveled shape, airflow in the air bag can be output outwards, strong airflow injection is generated on the leg of the ticket evading forward moving person, and the person can be prevented from evading the ticketand passing the gate.

The invention provides a bumper bracket and a bumper assembly with it, which relates to the technical field of bumpers and solves the problem that the existing heavy truck bumpers usually adopt hydraulic energy absorption and The honeycomb energy-absorbing structure, when a collision occurs, the joint area is relatively large, and it is easy to affect a large area, forcing the vehicle to be seriously damaged, and the energy-absorbing body is mostly set in the middle position, and it is difficult to cover the corner position, which is easy to cause The bumper is directly impacted, including the energy-absorbing shell; the left and right ends of the energy-absorbing shell are respectively fixed with vertical corner guards by bolts; the rear end of the corner guard and the horizontal insurance One end corresponding to the main body of the bar support is fixedly connected by bolts. In the present invention, because the lower end of the corner protector is fixedly equipped with a strong magnetic block whose lower end is inclined forward and downward, the tires are avoided from being damaged, and the driving safety is improved. Moreover, in order to avoid secondary falling off after adsorption, the supporting tray can play the role of receiving.

The invention discloses a cantilever-type lifting medical stretcher which comprises a bed stand, a lifting frame and a lead screw feeding mechanism. Casters are arranged at four bottom corners of the bed stand, a support frame is arranged on one side of the bed stand, a cantilever connected with the lifting frame is arranged on the upper portion of the support frame, a sleeve connected with the lifting frame is arranged in the middle of the support frame, the lifting frame is provided with a power mechanism, the lead screw feeding mechanism is positioned in the front of the lifting frame, and the front end of the lead screw feeding mechanism is connected with a bed board. The lifting frame together with the sleeve can vertically move along the supporting frame and is applicable to sickbeds with different heights, and the lead screw feeding mechanism can effectively advance and draw back the bed board. By the aid of the cantilever-type lifting medical stretcher, a patient can be effectively shifted to another bed and transferred, the pain of the patient is relieved, and the working pressure of medical workers is relieved. The cantilever-type lifting medical stretcher is unique in creation, convenient to use and easy to popularize.
