Abstract

The utility model provides a truckle tilting mechanism, including the collapsible device that has the truckle, treat that folding truckle links to each other with the activity stand through the upset post, collapsible device include the base of connecting through the stand pivot and activity stand, the upset post include expansion end and the stiff end of connecting through truckle pivot and reset spring, the truckle pivot is located upset post half department, wherein the stiff end is fixed with the base, folding truckle and expansion end fixed connection are treated to expansion end and activity stand fixed connection, the expansion end that promotes the upset post when the activity stand during around stand pivot upset overturns around the truckle pivot. The truckle can be folded automatically when collapsible device overturns, and the truckle is automatic when the device expandes, the time of having practiced thrift, has improved production efficiency.

Description

Castor switching mechanism

Technical field

This utility model relates to mechanical structure field, specifically a kind of castor switching mechanism.

Background technology

Castor, by sliding friction is become rolling friction, greatly reduces frictional force, provides a great convenience to people in daily life.But, castor there is also and takies exceptional space, the problem affecting object storage, such as deposit one's luggage bottom coach case time, the castor of luggage case results in the quantity deposited of luggage case and is substantially reduced.

Castor can realize simple folding and unfolding to save space by switching mechanism, the device that itself can fold for some, also wants first manual folding feet to take turns, waste time and energy, have a strong impact on automated production efficiency in commercial Application when folding device.

Utility model content

This utility model is in order to solve problem of the prior art, it is provided that a kind of castor switching mechanism, when folding device overturns, castor can be with auto-folder, the castor Automatic-expanding when device launches.

This utility model includes the folding device with castor, castor to be folded is connected with active column by upset post, described folding device includes base and the active column connected by column rotating shaft, described upset post is included the movable end connected by castor rotating shaft and back-moving spring and fixes end, castor rotating shaft is positioned at upset post 1/2nd, wherein fixing end is fixed with base, movable end is fixing with active column to be connected, castor to be folded is fixing with movable end to be connected, the movable end promoting upset post around column rotating shaft when active column overturns overturns around castor rotating shaft.

This utility model has the beneficial effects that: when folding device overturns, castor can be with auto-folder, and when device launches, castor Automatic-expanding, has saved the time, improves production efficiency.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Fig. 2 is utility model works process schematic.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

This utility model structure is as shown in Figure 1, including the folding device with castor, castor 2 to be folded is connected with active column 1 by upset post 6, described folding device includes base and the active column 1 connected by column rotating shaft 4, described upset post 6 is included the movable end connected by castor rotating shaft 5 and back-moving spring 3 and fixes end, castor rotating shaft 5 is positioned at upset post 1/6th two, wherein fixing end is fixed with base, movable end is fixing with active column 1 to be connected, castor 2 to be folded is fixing with movable end to be connected, the movable end promoting upset post 6 around column rotating shaft 4 when active column 1 overturns overturns around castor rotating shaft 5.

Utility model works mode is as shown in Figure 2:

When folding device folds, active column 1 overturns around column rotating shaft 4, promotes the movable end of upset post 6 to overturn around castor rotating shaft 5 simultaneously, and when the active column 1 of folding device folds, it is complete that castor overturns folding the most simultaneously, and now back-moving spring is stretched.

When folding device is opened, the movable end of upset post 6 resets without the pressure from active column 1, back-moving spring 3, pulls the movable end of upset post 6 to reset, and castor launches.

The concrete application approach of this utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model principle; can also make some improvement, these improvement also should be regarded as protection domain of the present utility model.

Claims
