The inner end of the lower connecting rod is hinged below the main frame through a lower inner shaft. And the upper connecting rod is hinged with the main frame through a hydraulic cylinder. According to the folding rack, part of the rack can be folded upwards at the edge through the connecting rod mechanism, the width of the rack is reduced during transportation, walking or carrying, transportation, walking or carrying is more convenient, and the folding rack can be applied to racks of various devices such as the agriculture industry, the mining industry or the building industry.

Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and particularly relates to a folding frame. Background Art

[0002] Current mechanical equipment sometimes has the problem of being too wide, for example, exceeding the width of the road surface, making it inconvenient to transport, move or carry. Utility Model Content

[0003] The utility model aims to provide a folding frame, which can fold part of the frame upwards at the edge by using a connecting rod mechanism, so as to reduce the width of the frame during transportation, walking or carrying, thereby making transportation, walking or carrying more convenient.

[0004] The technical solution adopted is:

[0005] A folding frame comprises a main frame and at least one side frame outside the main frame.

[0006] The main frame and the side frame are movably connected through a connecting rod mechanism.

[0007] The connecting rod mechanism comprises an upper connecting rod, a lower connecting rod and a hydraulic cylinder.

[0008] The outer end of the upper connecting rod is hinged through the upper outer shaft and the upper part of the side frame.

[0009] The inner end of the upper connecting rod is hinged to the upper part of the main frame through the upper inner shaft.

[0010] The outer end of the lower link is hinged through the lower outer shaft and the lower side frame.

[0011] The inner end of the lower link is hinged to the lower side of the main frame through the lower inner shaft.

[0012] The upper connecting rod and the main frame are hinged by a hydraulic cylinder.

[0013] Its advantages are:

[0014] The folding rack can fold part of the rack upwards at the edge using a connecting rod mechanism, so as to reduce the width of the rack during transportation, walking or carrying, making transportation, walking or carrying more convenient. The folding rack can be applied to racks of various equipment, such as agriculture, mining or construction industries. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A folding frame comprises a main frame 1 and at least one side frame 2 outside the main frame 1.

[0022] The main frame 1 and the side frame 2 are movably connected via a connecting rod mechanism.

[0023] In this embodiment, there are two side frames 2, which are respectively connected to the two sides of the main frame 1 through a connecting rod mechanism.

[0024] The connecting rod mechanism includes an upper connecting rod 3, a lower connecting rod 4 and a hydraulic cylinder 5.

[0025] The outer end of the upper connecting rod 3 is hinged to the upper side frame 2 through the upper outer shaft 6 .

[0026] The inner end of the upper connecting rod 3 is hinged to the upper part of the main frame 1 through the upper inner shaft 7.

[0027] The outer end of the lower connecting rod 4 is hinged to the lower side frame 2 through the lower outer shaft 8 .

[0028] The inner end of the lower connecting rod 4 is hinged to the lower part of the main frame 1 through the lower inner shaft 9.

[0029] The upper connecting rod 3 and the main frame 1 are hinged via a hydraulic cylinder 5 .

[0030] The upper end of the piston rod of the hydraulic cylinder 5 is hinged to the upper connecting rod 3 through the upper shaft 10.

[0031] The lower end of the cylinder body of the hydraulic cylinder 5 is hinged to the main frame 1 through a lower shaft 11.

[0032] When in use, when the frame is too wide, the piston rod of the hydraulic cylinder 5 extends to drive the side frame 2 to rise, leaving only the main frame 1, and the overall width is reduced. After passing through a narrow passage, the piston rod of the hydraulic cylinder 5 retracts to drive the side frame 2 to descend and restore the original width.

[0033] Existing equipment can be arranged on the main frame 1 and the side frame 2, for example, a no-tillage machine mechanism, i.e., a folding no-tillage machine, or other traveling mechanisms and working mechanisms can be arranged as needed, i.e., other folding equipment.
