The two telescopic mechanisms are respectively arranged at two sides of the structural members; two ends of each structural member are respectively fixedly provided with a rotating shaft; each set of the telescopic mechanism is a telescopic arm which is formed by the cross connection of two connection sheet chains with the rotating shaft of the structural members as the cross pivot; a plurality of connection sheets are hinged end to end in sequence to form each connection sheet chain; the middle of each connection sheet is provided with a shaft hole; and every two cross connection sheets are arranged on the same rotating shaft through a shaft hole. In the utility model, the mechanical strength of the lift device is high, and the operation process is stable.

Description

Lifting gear

Technical field

The utility model relates to a kind of lifting gear.

Background technology

Existing door and window is generally manual control, and elevating mechanism generally adopts reels mechanism, if adopt electronic control, there is operation problem stably inadequately in the elevating mechanism of this Scroll, and intensity is not high, is easy to damage.

The utility model content

The utility model technical problem to be solved is to propose a kind of lifting gear, and this lifting gear mechanical strength is high, and running is steady.

The technical solution of the utility model is following:

A kind of lifting gear is characterized in that, comprises a plurality of structural members, two cover telescoping mechanisms and is used to drive the actuating unit of this telescoping mechanism; Two cover telescoping mechanisms are separately positioned on the both sides of structural member; The two ends of each structural member respectively are installed with a rotating shaft; The described telescoping mechanism of every suit is for by the rotating shaft on two brace link structure spares being the telescopic arm that intersection fulcrum intersection links to each other and forms; Each bar brace chain is by many braces hinged the forming of head and the tail successively; The middle part of each root brace all is provided with axis hole, and the brace of per two intersections is contained in the same rotating shaft through shaft hole sleeve.

Described actuating unit comprises motor, traction steel wire and fixed pulley; Fixed pulley is fixed in the framework, and traction steel wire is walked around this fixed pulley, and the rotating shaft on the structural member of traction steel wire and below is in transmission connection, and the motor-driven traction steel wire drives the telescoping mechanism action.

Be fixed with a pulley in the rotating shaft of the structural member of below, traction steel wire is rounding on this pulley or traction steel wire is fixed on this pulley at least.

Described structural member is the steel pipe of Anti-theft door and window or the blade of shutter.

Described pulley, fixed pulley and traction steel wire each side are provided with a cover at structural member, and are symmetrical set.

Beneficial effect:

The lifting gear of the utility model adopts the telescoping mechanism based on telescopic arm, and drives novel structure through motor and traction steel wire; Mechanical strength is high, in addition, because the telescoping mechanism of structural member left and right sides symmetry; Through same motor-driven, so run time behaviour is steady, is easy to control.

The specific embodiment

Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:

Embodiment 1:

Shown in Fig. 1-4, a kind of lifting gear comprises a plurality of blades 3, two cover telescoping mechanisms and is used to drive the actuating unit of this telescoping mechanism; Two cover telescoping mechanisms are separately positioned on the both sides of blade 3; The two ends of each blade 3 respectively are installed with a rotating shaft 2; The described telescoping mechanism of every suit is for intersecting the continuous telescopic arm that forms of fulcrum intersection by the rotating shaft 2 on two brace link blades 3; Each bar brace chain is by many braces 1 hinged the forming of head and the tail successively; The middle part of each root brace 1 all is provided with axis hole, and the brace 1 of per two intersections is contained in the same rotating shaft 2 through shaft hole sleeve.Described actuating unit comprises motor 7, traction steel wire 6 and fixed pulley 5; Fixed pulley 5 is fixed in the framework of shutter, and traction steel wire 6 is walked around this fixed pulley 5, and the rotating shaft 2 on the blade 3 of traction steel wire 6 and below is in transmission connection, and motor-driven traction steel wire 6 drives the telescoping mechanisms action.Be fixed with a pulley 4 in the rotating shaft 2 of the blade 3 of below, traction steel wire 6 rounds on this pulley 4 at least.Described pulley 4, fixed pulley 5 and traction steel wire 6 each side are provided with a cover at blade 3, and are symmetrical set.

Course of work explanation: telescoping mechanism is a telescopic arm structure, and the vane group upper end is fixed in traction steel wire 6 drives of walking around fixed pulley 5 on the forms and is contained in the pulley 4 in the rotating shaft 2, thereby drives the lower end elongation of telescopic arm, finally drives all blades 3 and down moves; When blade 3 need upwards draw in, only need traction steel wire 6 drive pulleys 4 to move upward and get final product.

Fig. 3 only shows the telescoping mechanism on right side, and the mechanism in left side is in fact symmetrical fully with the right side.

Motor and transmission mechanism structure that driven vane 3 is gone up and down are as shown in Figure 4, and at first, the traction steel wire 6 of the left and right sides is installed in respectively on first rolling wheel 9 and second rolling wheel 12, thereby drive the rising and the decline of traction steel wire 6 final driven vane through rolling wheel; The output shaft of motor transmits torque on the gangbar 10 through gear train; Gangbar 10 drives first rolling wheel 9 and 12 rotations of second rolling wheel through bevel gear 11, so just drives the telescopic arm of the left and right sides simultaneously through a motor, and is simple in structure; Be easy to control, action synchronously and steadily.

Embodiment 2: change the blade among the embodiment 1 steel pipe of Anti-theft door and window into, can realize the up-down of Anti-theft door and window.

Above embodiment just in order to specify the structure of the utility model, is not the scope that is used to limit the utility model.
