Abstract
The utility model relates to a multiple parallel four-connecting-rod mechanism which comprises mounting plates, linear drives, parallel connecting rods and a connecting plate, wherein, the parallel connecting rods comprise inner parallel connecting rods and outer parallel connecting rods; the mounting plates comprise an upper mounting plate and a lower mounting plate; each linear drive comprises an inner linear drive and an outer linear drive; the four parallel connecting rods are fixed on the connecting plate through two rotating pins; and a plurality of sets of mounting plates, the linear drives, the parallel connecting rods and the connecting plates can be further embedded so as to form a multiple parallel four-connecting-rod moving mechanism. The utility model has the advantages that in the multiple parallel four-connecting-rod lifting mechanism, when the ratio between the weight-lifting and the deadweight is 2, the ratio between the lift and the shut height can reach 7 times; the weight is light, the closure distance is very small when the upper and the lower mounting plates are collected, and the multiple parallel four-connecting-rod mechanism is particularly applicable to occasions with small closure sizes; and the multiple parallel four-connecting-rod moving mechanism can be formed.
Description
Technical field
The utility model relates to a kind of multiple parallel four-bar linkage.
Background technology
At present, existing connecting rod mechanism mostly is three connecting rods or four-bar linkage greatly, but generally can only move up and down, and can not do horizontal motion; Existing connecting rod mechanism generally in lifting process since weight cross conference and shake, stable inadequately, therefore, only make double or triple connecting rods mostly, can not satisfy highly higher use needs, and closed distance is bigger when lower installation board closes up on the existing connecting rod mechanism, can't use in that the less occasion of closed size is installed.
The utility model content
The purpose of this utility model provides a kind of multiple parallel four-bar linkage, can only move up and down to overcome existing connecting rod mechanism, can not do horizontal motion, and tuple is few, the big deficiency of closed distance when last lower installation board closes up.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of multiple parallel four-bar linkage, comprise adapter plate, linear actuator, parallel connecting rod and connecting panel, parallel connecting rod and outer parallel connecting rod in described parallel connecting rod comprises, interior parallel connecting rod and outer parallel connecting rod respectively have two that are arranged above and below, be located on top interior parallel connecting rod and outer parallel connecting rod and be connected in connecting panel, be located on following interior parallel connecting rod and outer parallel connecting rod and be connected in connecting panel by a rotational pin by a rotational pin; Described adapter plate comprises top adapter plate and bottom adapter plate, and the top adapter plate is connected respectively by the interior parallel connecting rod of rotational pin with two vertical placements, and the bottom adapter plate is connected respectively by the outer parallel connecting rod of rotational pin with two vertical placements; Linear actuator and outer linear actuator in described linear actuator comprises, interior linear actuator two ends are connected by the interior parallel connecting rod of connecting pin with two vertical placements respectively, and outer linear actuator two ends are connected by the outer parallel connecting rod of connecting pin with two vertical placements respectively; Described connecting panel is fixed on four parallel connecting rods on the connecting panel by two rotational pins; Can embed some cover adapter plates, linear actuator, parallel connecting rod and connecting panel again, constitute multiple parallel four link work mechanisms.
The beneficial effects of the utility model are: dual parallel four connecting rod lifting mechanisms, and weight lifting and be 2 o'clock from anharmonic ratio is lifted high and the closed height ratio can reach 7 times; In light weight, closed distance was very little when last lower installation board closed up, the practical especially little occasion of closed size of installing; Can constitute multiple parallel four link work mechanisms.
