Problems solved by technology

The lifting structure hinged by this hinge method will cause many problems in the telescopic and lifting movements: 1. Rigid hinges need special shapes and structures to achieve stable hinges, so a lot of manpower is required for production and installation. Moreover, the hinge structure is complicated; 2. The hinge is a rigid part, which will cause friction with other components at the hinge, making the rotation of the hinge inflexible and increasing the rotational resistance; 3. The rigid hinge is not flexible, making the movement of the lifting structure Not flexible enough, prone to wear and even stuck, which reduces the service life of the lifting structure

Embodiment 1

[0029] Such as Figure 1-4 As shown, a flexible hinged lifting device is composed of a lifting frame and a driving device; the lifting frame is composed of a plurality of scissor-type units hinged in turn; the scissor-type unit is composed of two articulated arms 100, two The middle part of the articulated arm 100 is articulated by a rotating shaft 200, and the two ends of the articulated arm 100 are provided with articulated ends 300; the articulated ends 300 of the corresponding positions of the articulated arms 100 of two adjacent scissor-type units are connected by flexible The pieces 400 are connected in sequence; the lifting frame is a bracket structure with two ends that can be stretched; the flexible connecting piece 400 is made of nickel-titanium alloy, and bends with the expansion or folding of the scissor unit;

[0030] The driving device is arranged at one end of the lifting frame, and is used to drive the extension or folding of the scissor unit.

[0031] The hin...

Embodiment 2

[0036] Such as Figure 5As shown, in this embodiment, on the basis of Embodiment 1, the lifting frame is composed of two layers of bracket structures that can be stretched at both ends, and the corresponding hinged ends 300 of the two layers of bracket structures are connected by connecting rods. 600 connections fixed. The driving device is arranged between the two layers of the support structure of the lifting frame, so that the overall structure of the lifting frame is more stable, the driving is more stable, the weight it can bear is larger, and the use range is wider.

Embodiment 3

[0038] Such as Figure 6-9 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that: the flexible material is flexible plastic; The size of the articulated arm 100 is larger than that of the flexible connecting member 400, the flexible connecting member 400 is a sheet-like structure, and the articulated end 300 of the flexible connecting member 400 and its connected root articulated arm 100 is integrally formed . The articulated arm 100 and the flexible connecting piece 400 can be produced in an integrated manner, which is convenient for mass production in a production line, reduces the process of assembling the lifting device in the later stage, and is connected with the flexible connecting piece 400 to assemble and connect the two Compared with the solution of the articulated arm 100 described above, this connection method makes the connection between the flexible connecting member 400 and the articulated arm 100 more firm.

Abstract

The invention relates to the field of mechanical devices, in particular to a flexibly-hinged lifting device. The flexibly-hinged lifting device is composed of a lifting frame and a drive device. The lifting frame is formed by sequentially hinging a plurality of shear fork type units. The hinged ends of hinge arms between the shear fork type units are sequentially connected through flexible connecting pieces. The flexible connecting pieces are made of flexible materials and are bent along with unfolding or folding of the shear fork type units. According to the content, the flexibly-hinged lifting device is provided, and the hinged parts of the lifting frame arranged on the flexibly-hinged lifting device are hinged through the flexible connecting pieces; compared with hinging through a rigid mechanical component, the hinged parts of the flexibly-hinged lifting device are simple in structure and convenient to install, and due to the fact that the flexible connecting pieces are made of the flexible materials, the flexible connecting pieces have very good connecting strength and tenacity, and the lifting device can be maintained to conduct the unfolding or folding movement while mechanical jamming and other faults are not likely to happen; and meanwhile, later lubricating maintaining on the flexibly-hinged lifting device is not needed, and therefore the later maintaining cost of the lifting device is reduced.

Description

technical field [0001] The invention relates to the field of mechanical devices, in particular to a flexible hinged lifting device. Background technique [0002] In the field of application of mechanical devices, there are many ways to use mechanical components to realize the lifting and telescopic movement in the vertical direction, most of which are realized by hinged telescopic structures. [0003] However, in the existing lifting structure, the hinge part uses a rigid hinge to connect the components that need to be hinged together. The lifting structure hinged by this hinge method will cause many problems in the telescopic and lifting movements: 1. Rigid hinges need special shapes and structures to achieve stable hinges, so a lot of manpower is required for production and installation. Moreover, the hinge structure is complicated; 2. The hinge is a rigid part, which will cause friction with other components at the hinge, making the rotation of the hinge inflexible and i...
