Embodiment Construction

[0033] see figure 1 As shown, it is the rapidly foldable and unfoldable wheel frame mechanism of the present invention, which mainly includes:

[0034] A fixed frame 1, the fixed frame 1 has two fixed rods 11 arranged in parallel, at least one bushing 2 with at least three shaft holes can be sleeved on the two fixed rods 11, and through the described bushings 2 Position the two cross bars 12 between the two fixed bars 11 so that the two fixed bars 11 are stably positioned and parallel to each other;

[0035] Four sets of rotating parts 3, each of the rotating parts 3 is composed of a sleeve 31 and a wheel body 32, and the inner wall of the sleeve 31 is provided with a spiral guide groove 311 , the front end of the guide groove 311 is higher than the rear end, so that the two ends have a height difference and are not equal in height; the sleeves 31 of the four sets of rotating parts 3 are respectively sleeved on the two fixed rods 11 of the fixed frame 1 On the front and rear...

Abstract

The invention relates to a wheel frame mechanism which can be rapidly folded and unfolded, the wheel mechanism comprises: a fixing frame; at least two groups of rotating parts, wherein, every group of rotating parts is composed of a sleeve and a wheel body which are combined and connected, a spiral guide channel with different heights of the two ends is arranged on the sleeve, and the sleeve drives the wheel body to rotate around a fixing bar; a movable frame which is equipped with two parallel movable bars and at least one crossbar for fixing the two movable bars, wherein, the two movable bars are respectively equipped with a guide shaft in a way of extruding which extrudes out of the bottom of the movable bars, the movable frame is arranged above the fixing frame, and the guide shaft of the movable bar is arranged in and penetrates the guide channel of the sleeve of the rotating parts; a stretching bar which is equipped with an internal bar and an external bar that are sheathed mutually and is connected with a latch part for controlling the stretching of the internal bar. The opening and the closing of the latch part is controlled by a handle. The external bar of the stretching bar is fixedly connected with the crossbar of the fixing frame, and the end part of the internal bar is fixedly connected with the crossbar of the movable frame.

Description

technical field [0001] The invention relates to a wheel frame mechanism. Background technique [0002] Depending on the size of the wheel diameter, the scope of use of the wheels is also different. Taking nursing wheelchairs and trolleys as examples, they all use wheels with small wheel diameters. The wheels of wheelchairs or casters / trolleys are installed on the wheel frame, and Through the wheel frame, the wheels can be combined with carts, chairs or other products. Driven by the wheels, heavy objects can be easily carried, which saves time and effort. [0003] However, although the wheeled car is practical, it still has the following deficiencies in the application composition: [0004] The existing casters cannot be folded, which makes it inconvenient to carry and carry. [0005] When the existing trolley is carried empty (such as being placed in the luggage compartment of a truck or a car), it is easy to slide. [0006] It can be seen that the existing wheel frame st...
