Example one
As shown in fig. 1 to 7, a lifting column D1 used for a medical shift vehicle and having a safety release function is mounted on a chassis of the shift vehicle, and comprises an outer tube D11 and an inner tube D12, wherein the inner tube D12 is fixedly connected with the chassis of the shift vehicle, the outer tube D11 is driven by an electric push rod to extend and retract along the outer wall of the inner tube D12, the electric push rod is arranged at the bottom of the inner side of the inner tube, the electric push rod is provided with a safety release device D14, and the safety release device D14 is provided with a safety release switch D141.
To facilitate operation of safety release switch D141, safety release device D14 is located inside the bottom of the inner tube and safety release switch D141 extends below safety release device D14. Still include simultaneously that the safety release link assembly D15 is used for pressing safety release switch D141, safety release link assembly D15 includes horizontal migration connecting rod D151 and rotation connecting rod D152, safety release button D153 is connected to the one end of horizontal migration connecting rod D151, and rotation connecting rod D152 is connected to the other one end, rotation connecting rod D152 is equipped with the roof that upwards promotes safety release switch D141.
Act on safety release switch D141 through safety release link assembly D15, only need press the safety release button D153 of establishing in the vehicle chassis side of shifting, just can make the lift stand promptly descend, conveniently operate. The safety release button D153 is positioned on the side surface of the chassis of the shifting vehicle, and can be a front side surface, a left side surface, a right side surface or a rear side surface, and a nursing object can operate by bending down or by a nursing person.
The rotating connecting rod D152 comprises a vertical section and a horizontal section which are connected into a V shape, the bottom of the vertical section is hinged with the horizontal moving connecting rod, the connecting part of the vertical section and the horizontal section is rotatably connected with the rotating shaft, and the top plate is arranged on the horizontal section. In order to guide the horizontal linear movement of the horizontal moving link D151, the horizontal moving link D151 is slidably coupled to the guide hole. The safety release button D153 is only required to be pressed, and the rotating connecting rod D152 can be driven, so that the top plate pushes the safety release switch D141 upwards, and the operation experience is further improved.
The safety release switch D141 of the safety release device has a return structure, and can be reset after the safety release button D153 is released, so as to push the safety release link assembly D15 to return. Of course, in order to ensure that the safety release button D153 can be accurately reset, a reset spring may be connected to the safety release button D153.
Referring to fig. 6, the guide rail includes a guide rail bar D111 connected to the outer tube D11 and a guide rail slider D122 connected to the inner tube D12, the guide rail slider D122 having a guide rail groove slidably engaged with the guide rail bar D111. The traditional lifting upright is in a vertical state, but because in the embodiment, the lifting upright is arranged in a backward inclining mode, the traditional guide rail sliding block is short and is easy to deform or even damage when being subjected to large force, and the force applied to the lower part of the rear side is borne in a use state. In order to increase the contact area between the guide rail slider D122 and the guide rail strip D111, the length of the guide rail slider D122 is greater than one third of the length of the inner tube D12, so that a larger force bearing area is ensured between the guide rail slider D122 and the guide rail strip D111. Those skilled in the art will appreciate that the rail runner D122 may be as long as the length of the inner tube D12.
Those skilled in the art will understand that the relative movement relationship between the outer tube D11 and the inner tube D12 can be interchanged, and the relative movement relationship between the guide rail D111 and the guide rail slider D122 can also be interchanged.
Further, the guide rail slider D122, which has at least one fifth of the length of the inner tube D12, remains engaged with the guide rail bar D111 when the outer tube D11 is extended upward to the limit position. Even if a large backward pressure is applied, the guide rail sliding block, the inner pipe and the outer pipe are not easy to deform and are not easy to be damaged by stress. Those skilled in the art will appreciate that the rail block D122 may be a through structure extending from the bottom end to the top end of the inner tube, but may also be a split structure having at least two parts.
In addition, a gap is formed between the outer tube D11 and the inner tube D12, so that the outer tube D11 is easy to shake during expansion and contraction, and when the outer tube D11 extends upward and is subjected to a large external force, the gap between the outer tube D11 and the inner tube D12 is large, so that the outer tube is easy to deform under force, and a backing plate D13 supported on the outer wall of the inner tube is connected to the inner wall of the lower front side of the outer tube or/and a backing plate D13 supported on the inner wall of the outer tube is connected to the outer wall of. When the outer tube D11 is extended upward and is subjected to a large rearward and downward pressure, the pad D13 is supported at the front while being supported at the rear by the guide rails, so that a large supporting force is ensured between the outer tube D11 and the inner tube D12, and the inner and outer tubes are not easily deformed by the force.
Referring to fig. 5 to 7, the horizontal projection of the lifting column is in a shape with a narrow front part and a wide rear part and gradually changed width, the shape is similar to an isosceles triangle, the corners are in arc transition, and the backing plate D13 is arranged at the corner position of the front side of the isosceles triangle. Simultaneously, two groups of guide rails are arranged on the left side and the right side of the rear part of the lifting upright column side by side. The inner pipe can bear larger downward pressure through increasing the number of the guide rails. The left side and the right side of the rear portion of the inner tube are respectively provided with a vertically extending type groove D121, and the guide rail is arranged in the type groove D121 so as to facilitate installation of the guide rail and save and utilize the space between the inner tube and the outer tube.
In one embodiment, the guide rail is a V-shaped guide rail, so that the guide rail slider D122 has a larger contact area with the guide rail bar D111, and can bear a larger downward force and a certain lateral force. Of course, it will be appreciated by those skilled in the art that a dovetail type rail or other existing rail configuration may be substituted.
In order to reduce the friction of the guide rail, the wear is reduced. And a self-lubricating nylon bush D123 is arranged in the guide rail groove. The friction coefficient of nylon is reduced along with the increase of load, and can be reduced to about 0.1-0.15 under the condition of high load, so that the nylon has better lubricating property. And the nylon has good abrasion resistance. Here for installing self-lubricating nylon bush D123, the inner wall in guide rail groove is equipped with the caulking groove, self-lubricating nylon bush gomphosis is in the caulking groove and the veneer is fixed.
In addition, the outer tube D11 and the guide rail strip D111 are metal profiles of an integral structure, so that the integral processing and forming are facilitated. The inner pipe D12 and the guide rail sliding block D122 are both metal profiles and are fixed together by screws, and the inner pipe D12 and the guide rail sliding block D122 are assembled together with the outer pipe D11 after being installed.
