Abstract
The utility model relates to an automatic telescopic trundle which belongs to the technical field of machinery and comprises a trundle, a metal rod with a circular hole at the upper end, a compression spring, two bracket baffles with circular holes and a pin, wherein the diameters of the circular holes of the two bracket baffles are matched with the diameter of the circular hole of the metal rod; the metal rod is fixedly connected with the upper end of the trundle, the compression spring is sheathed on the metal rod, the bracket baffles are arranged at the upper end of the compression spring on the metal rod through the circular holes, and the pin 6 is arranged in the circular hole at the upper end of the metal rod. When the automatic telescopic trundle is in idle loading, the normal moving of furniture or a conveying tool can be ensured; when in loading, the automatic telescopic trundle can automatically retract, so that the furniture or the conveying tool can be in direct contact with the ground to bear the load. Compared with the traditional trundle, the automatic telescopic trundle has the following characteristics: the service life of the trundle is prolonged, the size of the trundle is reduced and the manufacturing cost is lowered; in addition, when in loading, the automatic telescopic trundle is firmer and more stable, so that the comfort degree is improved.
Description
Technical field
The utility model relates to a kind of castor, and especially a kind of automatically flexible castor belongs to field of mechanical technique.
Background technology
During modern furniture and transportation means were made, castor had obtained using widely.Castor, in most occasion is to be that the form of a group (three pieces or four pieces is a group often) is installed in below the object with several pieces, make that this furniture or transportation means can be able to move smoothly, not only both improved work efficiency, and made things convenient for people's life again.
Yet this traditional caster wheel has some shortcomings, mainly shows:
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 wish that furniture that some is equipped with castor or transportation means when needs keep the stationary fixing state, are difficult to realize user's hope because castor is very easily mobile.
The invention of the flexible automatically castor of the utility model has overcome above-mentioned shortcoming on bigger degree, can be so that furniture or transportation means when underload, can equally with traditional object move freely sleekly; And when heavy duty, this castor can be withdrawn automatically, makes the direct contact of furniture or transportation means ground own bear load.
Summary of the invention
The purpose of this utility model is to solve existing castor to bear weight load and loss thereof, low defective of life-span.
The technical solution of the utility model is:
A kind of automatically flexible castor, comprise: castor, metallic support rod, compression spring, two horizontal baffles and pin, wherein, at circular hole of the top of metallic support rod processing, a circular hole is arranged on two horizontal baffles, and the size of circular hole and the external diameter of metallic support rod are complementary; Adjunction metallic support rod on castor is laid two horizontal baffles on metallic support rod, compression spring is placed in the lower end of horizontal baffle below, inserts pin on the circular hole on metallic support rod top.
The utility model is achieved in that at furniture or transportation means direction perpendicular to the ground fixes two plane baffle plates parallel to the ground respectively, and the circular hole particular location guarantees can make after metallic support rod is inserted metallic support rod and ground to keep vertical in two horizontal baffles.Following horizontal baffle guarantees that compression spring is compressed, and top horizontal baffle guarantees to connect metallic support rod can free vertical shifting up and down.So when furniture or transportation means when idling carries, the castor that should stretch automatically relies on the elastic force of coil tension spring, automatically keep stretching out state, make the automatically flexible castor itself can direct contact ground, can move freely to guarantee this furniture or transportation means; When this automatically flexible castor was born load, the compression spring that is enclosed within on the strut bar was compressed, and castor is withdrawn, and makes the direct contact ground, bottom of furniture or transportation means, and flexible automatically castor is not born load.
The beneficial effects of the utility model are: use automatically flexible castor of the present utility model, when idling carries, can guarantee that furniture or transportation means normally move; When load was arranged, this kind castor can be withdrawn automatically, made furniture or transportation means direct contact ground bear load.This automatically flexible castor is compared with traditional castor, increase castor service life, reduce to use the caster wheel size, reduce manufacturing cost and when load, firm more, stable, increased comfort.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Wherein, 1-castor, 2-metallic support rod, 3-compression spring, 4-horizontal baffle a, 5-horizontal baffle b, 6-pin.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
A kind of automatically flexible castor, comprise: castor 1, metallic support rod 2, compression spring 3, horizontal baffle a4, horizontal baffle b5 and pin 6, wherein, at circular hole of the top of metallic support rod 2 processing, a circular hole is arranged on horizontal baffle a4, the horizontal baffle b5, and the external diameter of the size of circular hole and metallic support rod 2 is complementary; Adjunction metallic support rod 2 on castor 1 is laid horizontal baffle a4, horizontal baffle b5 on metallic support rod 2, place compression spring 3 in the lower end of horizontal baffle a4, inserts pin 6 on the circular hole on metallic support rod 2 tops.
The utility model is achieved in that at furniture or transportation means direction perpendicular to the ground fixes two plane baffle plates parallel to the ground respectively, and the circular hole particular location guarantees can make after metallic support rod is inserted metallic support rod and ground to keep vertical in two horizontal baffles.Following horizontal baffle guarantees that compression spring is compressed, and top horizontal baffle guarantees to connect metallic support rod can free vertical shifting up and down.So when furniture or transportation means when idling carries, the castor that should stretch automatically relies on the elastic force of coil tension spring, automatically keep stretching out state, make the automatically flexible castor itself can direct contact ground, can move freely to guarantee this furniture or transportation means; When this automatically flexible castor was born load, the compression spring that is enclosed within on the strut bar was compressed, and castor is withdrawn, and makes the direct contact ground, bottom of furniture or transportation means, and flexible automatically castor is not born load.
The utility model is not limited to the above-mentioned specific embodiment, needs only which kind of shape of employing, sizes such as elastomeric element such as coil tension spring is installed in the automatically flexible castor, all drops within the protection domain of the present utility model.
