Abstract
The utility model discloses a kind of double link lifting mechanism.This lifting mechanism comprises actuator lever and the follower lever that intersection is rotatably connected; The upper end of actuator lever and the lower end of follower lever are rotationally connected with respectively upper and lower two cross bars, and the upper end of follower lever is rotationally connected with cross tube and can does certain distance along its cross bar direction and slide, and the lower end of actuator lever is rotationally connected with an action switching mechanism; This action switching mechanism comprises the rotating thread rod that is fixed on sheer pole and is arranged on the rotating part matching on thread rod, the rotating lower end that is connected in actuator lever of this rotating part.The utility model has also done certain improvement on the comformability of this mechanism.
Description
Technical field
The utility model relates to a kind of lifting mechanism taking double link as main body.
Background technology
The lower end of existing its actuator lever of double link lifting mechanism is directly connected with sheer pole, and in operation, the pressure that lifting mechanism bears acts directly on lower end and the sheer pole contact site of actuator lever.Carrier is heavier, and friction force is larger, and lifting needs very large application force.
Utility model content
The utility model object is to provide a kind of lifting mechanism that solves foregoing problems.
A kind of double link lifting mechanism, comprise actuator lever and follower lever that intersection is rotatably connected, the upper end of actuator lever and the lower end of follower lever that are positioned at homonymy are rotationally connected with respectively upper and lower two cross bars, the upper end of follower lever is rotationally connected with cross tube and can does certain distance along its cross bar direction and slide, and the lower end of actuator lever is rotationally connected with an action switching mechanism; This action switching mechanism comprises the rotating thread rod that is fixed on sheer pole and is arranged on the rotating part matching on thread rod, the rotating lower end that is connected in actuator lever of this rotating part.
Because the lower end of its actuator lever of lifting mechanism under this structure is connected with the rotating part of being located on thread rod, avoid actuator lever lower end to be directly connected with sheer pole the defect of bringing.
As improvement, described thread rod is connected in a rotating shaft by driving band.
As improvement, described thread rod is provided with belt wheel with the position that rotating shaft contacts with driving band.
The effect of this structure aforementioned improved is to only have a position with respect to the thread rod before improving, and the installation site of rotating shaft has larger arrangement space, thereby Shi Ben mechanism has larger comformability.
Brief description of the drawings
This structural scheme of mechanism of Fig. 1
Detailed description of the invention
As shown in Figure 1, actuator lever 1 and follower lever 2 intersections are rotatably connected, and the lower end of the upper end of actuator lever 1 and follower lever 2 is connected and cross tube 3 and sheer pole 4 successively; The upper end of follower lever 2 is rotationally connected with cross tube 3, can slide along notch 31; The lower end of actuator lever 1 is connected in an action switching mechanism.
This action switching mechanism comprises the thread rod 5 and the rotating part matching 6 disposed thereon that are rotatably fixed on sheer pole 4 by permanent seat 7; Rotating part 6 is rotatably connected with the lower end of actuator lever 1.
The manner of execution of this mechanism is that turn thread rod 5, drives rotating part 4 to move axially along thread rod, thereby drives the actuator lever 1 being attached thereto to move, and realizes the up-and-down movement of mechanism.
Continue to see Fig. 1, following improvement has also been done by this mechanism: thread rod 5 is connected in a rotating shaft 9 by driving band 8; The position that thread rod 5 and rotating shaft 9 contact with driving band 8 is provided with belt wheel 10 and belt wheel 11 successively.
This improved consideration is, if while directly making troubles because of the consideration of the factors such as space taking thread rod 5 as control lever, utilize the effect of driving band 8, rotating shaft 9 can be arranged in theory on the optional position of a week of thread rod 5, thereby increases the comformability of this mechanism.Even, can, by establishing the mode of multiple rotating shafts, further tackle very situation, certainly, which also belongs to the protection domain of this design.
