Below with reference to the accompanying drawings folding castor according to the utility model embodiment is described.
As Figure 1-Figure 5, base 100, the and of castor assembly 200 are included according to the folding castor of the utility model embodiment
Elastic component 400.
Castor assembly 200 is installed in rotation on base 100 between extended and collapsed positions.Elastic component 400
It is connected respectively with base 100 and castor assembly 200, elastic component 400 is provided castor assembly 200 from described folding position (such as Fig. 3
It is shown) often push the elastic force of the expanded position (as shown in Figure 2) to.
Need exist for being appreciated that, castor assembly 200 can be supported in ground when being located at expanded position, so as to carry heating
The products such as device move, such as set down and stretch out base in the horizontal direction when castor assembly 200 is located at the expanded position
100；
When castor assembly 200 is located at folding position and base 100 is in folded state, is accounted for so as to reduce the entirety of folding castor
Towards horizontal direction and the lower section of base 100 is accommodated in when being located at the folding position with space, such as castor assembly 200.
In addition, elastic component 400 provides often pushes castor assembly 200 to the exhibition from the folding position (as shown in Figure 3)
The elastic force of open position (as shown in Figure 2) is a relative power, and is not necessarily referring to castor assembly 200 and completely can not in expanded position
Rotate, when the external force of application is sufficiently large, above-mentioned elastic force can be overcome and castor assembly 200 is turned to folding position.
According to the folding castor of the utility model embodiment, it is connected respectively with castor assembly 200 and base 100 by setting
Elastic component 400, using the pretension elastic force of elastic component 400, often push castor assembly 200 to expanded position from folding position, together
When the elastic force positioning action is played to castor assembly 200, instead of in correlation technique frictional force position, by castor assembly 200
Be maintained at the expanded position for being easy to work, greatly reduce frictional force positioning belt come abrasion, so as to effectively improve use can
By property and service life.Therefore, use reliability height, long lifespan are had the advantages that according to folding castor of the present utility model.
When product packaging is transported, the elastic force of elastic component 400 can be overcome by external force, castor assembly 200 is turned to folding
Folded position, in order to store, reduce space-consuming
Below with reference to the accompanying drawings folding castor according to the utility model specific embodiment is described.
As Figure 1-Figure 5, base 100, the and of castor assembly 200 are included according to the folding castor of the utility model embodiment
Elastic component 400.
Specifically, as Figure 1-Figure 5, castor assembly 200 includes trundle bracket 230 and universal wheel 240.Trundle bracket
230 are installed in rotation on base 100, and elastic component 400 is connected with trundle bracket 230 and base 100 respectively.Universal wheel 240
On trundle bracket 230.Wherein, trundle bracket 230 is used to drive castor assembly 200 overall in expanded position and folding position
Rotated between putting, and when castor assembly 200 is in the deployed, universal wheel 240 can realize each water by the rotation of itself
Square upward movement.
For example, trundle bracket 230 is horizontal (as shown in Figure 2) when castor assembly 200 is in the deployed, pin
Trundle bracket 230 is in vertical state (as shown in Figure 3) when wheel assembly 200 is in folding position.
Further, in order to when castor assembly 200 is in the deployed, ensure to fold the stationarity of castor movement, ten thousand
To wheel 240 pivot center perpendicular to trundle bracket 230 pivot center.
In some specific embodiments of the present utility model, as Figure 1-Figure 5, base 100 has support feet 110, branch
Spike 110 is extended downwardly and is arranged in pairs from base 100, and castor assembly 200 is installed in rotation at least one pair of support feet 110
On.
Specifically, as Figure 1-Figure 5, castor assembly 200 is installed in rotation on base 100 by hinge axis 310
In support feet 110, it is combined with hinge axis 310 for carrying out spacing gear to castor assembly 200 in the axial direction of hinge axis 310
Pin 320.For example, a part for trundle bracket 230, between a pair of support feets 110, hinge axis 310 is each passed through this to support
Pin 110 and trundle bracket 230 positioned at this to the part between support feet 110, one end of hinge axis 310 has gear cap and another
End has radial perforation, and backing pin 320 coordinates in radial perforation, and backing pin 320 and gear cap are located at two to support feet 110 respectively
Side, so as to which castor assembly 200 is installed in rotation on base 100, and realize castor assembly 200 on base 100
Axially position.
In some specific examples of the present utility model, as Figure 1-Figure 5, elastic component 400 is torsion spring and is set in hinge
On chain rivet 310, the both ends of elastic component 400 are tangentially projecting, and one end 410 of elastic component 400 is against the trundle bracket of castor assembly 200
On 230, and the other end of elastic component 400 is against on base 100.The certain prefastening torque bullet preset when mounted of elastic component 400
Power, the elastic force is transferred to trundle bracket 230 using one end 410 of elastic component 400 after installation, and utilizes the other end of elastic component
The elastic force is transferred to base 100 by 420, so as to often push castor assembly 200 to expanded position, and keeps certain coupling mechanism force.
Further, as shown in figure 4, the trundle bracket 230 of castor assembly 200 is provided with effect beam 231, elastic component 400
One end 410 be against effect beam 231 on, one end 410 of elastic component 400 is by acting on moment of torsion elastic force transmission of the beam 231 by pretension
To trundle bracket 230, and then the castor assembly 200 for being pointed to expanded position provides certain coupling mechanism force.
Further, as shown in figure 4, effect beam 231 has effect inclined-plane 232, castor assembly 200 is located at expanded position
When, effect inclined-plane 232 is obliquely installed relative to horizontal direction, and one end 410 of elastic component 400 is against on effect inclined-plane 232, thus
Can be in order to the transmission supported and for pretension elastic force that stops preset the elastic component 400 of pretension elastic force with act on beam 231, raising
The reliability that one end 410 of elastic component 400 coordinates with effect beam 231.
Alternatively, the fixation for the ease of effect beam 231 and one end 410 of elastic component 400 and matching somebody with somebody for effect beam 231
Close, ensure that the pretension elastic force of elastic component 400 often pushes castor assembly 200 to expanded position, trundle bracket 230 is provided with recess
233, effect beam 231 is located in recess 233 and acts on two side of the both ends of beam 231 respectively with recess 233 and is connected.
In some specific examples of the present utility model, castor assembly 200 is two and respectively positioned at the two of base 100
Side, when two castor assemblies 200 are respectively positioned on expanded position, common support and bearing base 100, base 100 is driven steadily to move.
Below with reference to the accompanying drawings warmer 10 according to the utility model embodiment is described, as shown in figure 1, new according to this practicality
The warmer 10 of type embodiment includes the folding castor according to the utility model above-described embodiment.
Alternatively, base 100 can be made up of the bottom wall of the shell of warmer.
According to warmer 10 of the present utility model, by using the folding castor according to the utility model above-described embodiment,
Easy to remove and complete machine packaging, and there is use reliability height and long lifespan.
