Abstract
The utility model provides an adjustable universal castor. The adjustable universal castor is a pneumatic piston type castor which is connected up by and composed of a cylinder body, a piston, a spherical body, a ring seat and an air valve. The spherical body can be adjusted to rise and fall as required. When the utility model is positioned for a long time for carrying articles, the spherical body of the caster not bear weight. The utility model has novel structure, and flexible and convenient use. The utility model can be used on electric appliances such as refrigerators and washers, furniture, machines, tools, etc. The utility model is a novel adjustable universal castor.
Description
The utility model relates to a kind of castor, is a kind of universal type ball castor particularly.
For the ease of the placement of article with move, the universal type ball castor is housed on article such as furniture, electrical equipment usually.Castor mainly is to adopt rubber spheroid, ball, connection frame to connect to form.But because the spheroid of existing castor easily causes spheroid distortion, ball displacement so that castor damages, and ineffective, it is unstable that the article that carry are tilted in article are long-time heavys burden of directly contacting to earth in placing, influence is use normally.
The purpose of the utility model provides a kind of improved universal type ball castor, and it can make the spheroid lift adjustment, make when article are long, place in not load of spheroid, it is flexible and convenient to use.
For achieving the above object, solution of the present utility model is: adopt the Pneumatic piston universal caster wheel that is connected to form by cylinder block, piston, spheroid, ball and ring seat, spheroid is by the aperture of stop collar load in piston, piston is loaded in the hole of cylinder block, on the lateral body of the endoporus top of cylinder block, tire tube valve is housed, load ring seat on the aperture, cylinder block bottom, the upper top of cylinder block is inlayed intrinsic tie bolt.During use, castor is installed in the bottom of institute's bearing article by its tie bolt, also several castors can be interconnected with tracheae.Move the article of carrying as need, inflate by tire tube valve, gas enters the interior piston that promotes of cylinder and moves down together with spheroid, and is by ring seat that piston is spacing, spheroid contacted to earth support article, can move easily, when article lay safe after, open valve and discharge gas, move on piston and the spheroid return, make its ring seat and cylinder block supports articles, spheroid is in free state.
Also can be positioned at air bag of top arrangement of piston in cylinder-bore, air bag connects the tire tube valve on the bank.In air bag, inflate during use, air bag bulging promotion piston and spheroid are moved down support the article that carried, move and lay.
Because the utility model has adopted the Pneumatic piston universal caster wheel, makes spheroid can carry out lift adjustment as required, especially in the long-time placement of bearing article, the spheroid of castor does not bear weight, has improved the service life of castor greatly.Its novel structure, flexible and convenient to use.Can be widely used in electrical equipment and various furniture, facility etc. such as electric refrigerator, laundry machine, be a kind of later-model adjustable universal caster wheel.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the cutaway view of first embodiment concrete structure of the utility model.
Fig. 2 is the upward view of Fig. 1 embodiment.
Fig. 3 is the structure cutaway view of another embodiment band air bag castor.
Fig. 4 is 4 monomer castors of the utility model tracheae bonded assembly scheme drawings.
As shown in Figure 1, spheroid of the present utility model (2) by stop collar (9) load in the aperture of piston (8), ball (4) company of touching in spheroid (2) top and piston (8) hole, piston (8) is loaded in the endoporus of cylinder block (5) and by the spacing connection of ring seat (1) of cylinder block (5) orifice part load, on the lateral body of the endoporus top of cylinder block (5) tire tube valve (7) is housed, the upper top of cylinder block (5) is inlayed intrinsic tie bolt (6).For making piston (8) and cylinder block (5) hole wall form running-fit closely, on piston (8), be inlaid with seal ring (3).
As shown in Figure 3, the utility model or in cylinder block (5) endoporus, be positioned at the air bag of top arrangement (10) of piston (8), air bag (10) connects the tire tube valve (7) on cylinder block (5) lateral body, makes piston (8) need not adorn seal ring (3).
Claims (4)
1, a kind of adjustable universal type castor that contains spheroid (2), ball (4) and tie bolt (6), it is characterized in that this castor also comprises piston (8), cylinder block (5), stop collar (9) and ring seat (1), spheroid (2) by stop collar (9) load in piston (8) aperture, piston (8) is loaded on the endoporus of cylinder block (5) and by the spacing connection of ring seat (1) of cylinder block (5) orifice part load, on the lateral body of cylinder block (5) endoporus top tire tube valve (7) is housed.
