Abstract
The utility model provides a telescopic fall-ball type swivel caster, which comprises a caster body, a metal support rod, a spring, a first horizontal baffle plate, a second horizontal baffle plate and a dowel, wherein one end of the metal support rod is fixed in a shell of the caster body in a rotating way, and the other end of the metal support rod sequentially penetrates through the spring, the first horizontal baffle plate and the second horizontal baffle plate; one end of the spring is pressed against the bottom of the first horizontal baffle plate, and the other end of the spring is pressed against the shell of the caster body; the dowel is inserted into the metal support rod above the second horizontal baffle plate; the caster body mainly comprises the shell, balls, four support zero-type balls, a screw and a pressure plate; the four support zero-type balls are arranged in the shell to form an array; the balls are arranged between the support zero-type balls and the shell; the pressure plate is fastened at the bottom of the shell through the screw; and four round holes for positioning the support zero-type balls are reserved in the pressure plate, and are matched with corresponding support zero-type balls respectively. Contact points between the caster body and the ground are added, so that each support zero-type ball is uniformly loaded, and the service life of the support-zero-type balls is prolonged.
Description
Technical field
The utility model relates to the technical field of machine parts, refers in particular to a kind of telescopic four ball-type universal caster wheels.
Background technology
During modern furniture and transportation means were made, castor had obtained using widely, but also there are some shortcomings in traditional caster wheel, and specifically have: 1, castor will bear the load of weight body for a long time, causes castor very easily to damage, and then causes its service life of short duration; 2,, make and to hope that some is equipped with furniture or transportation means when needs keep the stationary state, is difficult to realize user's requirement because castor is very easily mobile.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of reasonable in design reliable, stressed evenly, rotate flexibly, the telescopic four ball-type universal caster wheels of long service life.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of telescopic four ball-type universal caster wheels, and it includes the castor body, and it also includes metallic support rod, spring, first horizontal baffle, second horizontal baffle, pin; Wherein, Described metallic support rod one end is rotatably installed in the housing of castor body, and its other end passes spring, first horizontal baffle, second horizontal baffle successively, and inconsistent bottom spring one end and first horizontal baffle; Its other end contacts at the housing of castor body, and pin is inserted on the metallic support rod of second horizontal baffle top; Described castor body mainly is made up of housing, ball, four zero balls, screw and pressing plates; These four zero ball array are arranged in the housing; And lay ball between each zero ball and the housing; Pressing plate is anchored on housing bottom through screw simultaneously, and offers four on this pressing plate to a circular hole that zero ball positions, and matches with corresponding zero ball respectively.
It is spherical in shape that the housing of described metallic support rod and castor body rotates the position of installing.
The utility model is after having adopted such scheme, and its great advantage is that the utility model has increased castor body and ground contact point, and makes each zero ball-joint carry evenly, rotates flexibly the service life of prolongation itself; The utility model can make the direct contact of furniture or transportation means ground own bear load so that furniture or transportation means when underload, can equally with traditional object move freely sleekly, and when heavy duty, can withdraw automatically simultaneously.
Description of drawings
Fig. 1 is the scheme drawing of the utility model.
Fig. 2 is the birds-eye view of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1 and accompanying drawing 2; The described telescopic four ball-type universal caster wheels of present embodiment; It includes castor body 1, metallic support rod 2, spring 3, first horizontal baffle 4, second horizontal baffle 5, pin 6, and wherein, described metallic support rod 2 one ends are rotatably installed in the housing 7 of castor body 1; Its other end passes spring 3, first horizontal baffle 4, second horizontal baffle 5 successively; And spring 3 one ends and first horizontal baffle, 4 bottoms are inconsistent, and its other end contacts at castor body 1, and pin 6 is inserted on the metallic support rod 2 of second horizontal baffle, 5 tops; Described castor body 1 mainly is made up of housing 7, ball 8, four zero balls 9, screw 10 and pressing plates 11; These four zero ball 9 array arrangements are in housing 7; And lay ball 8 between each zero ball 9 and the housing 7; To realize that four zero balls 9 rotate flexibly, pressing plate 11 is anchored on housing 7 bottoms through screw 10 simultaneously, and offers four on this pressing plate 11 to a circular hole that zero ball 9 positions; Match with corresponding zero ball 9 respectively, make that four zero balls 9 can not come off when the utility model broke away from ground.Because it is spherical in shape that metallic support rod 2 of the utility model and the housing of castor body 17 rotate the position of installing, and makes the utility model caster wheel body 1 be convenient to flexible rotation, and its four zero balls 9 are stressed even.In a word, the utility model has increased castor body 1 and ground contact point, and makes each zero ball 9 carry evenly, rotates flexibly the service life of prolongation itself; Simultaneously the utility model can be so that furniture or transportation means when underload, can equally with traditional object move freely sleekly, and when heavy duty; Can withdraw automatically; Make the direct contact of furniture or transportation means ground own bear load, make the utility model more firm when load, safe and reliable; Durable in use, be worthy to be popularized.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
