Abstract
The utility model discloses a stably placed trailer which comprises a trailer body and supporting legs that are rotatablely connected at the four corners of the trailer body, wherein each supporting leg comprises a supporting leg body, a ball joint and a supporting seat sheathed on the ball joint in a free arrangement way; and the ball joints are fixedly connected at the lower ends of the supporting leg bodies. The stably placed trailer has the advantages that the supporting seat are sheathed on the ball joints, and the ball joints can be freely arranged according to the angle of inclination of the ground and are parallel to the ground, so that workpieces on the trailer can be stably arranged.
Description
Technical field
The utility model relates to a kind of vehicle instrument, is meant a kind of steadily trailer of placement of being convenient to especially.
Background technology
Trailer can be realized the carrying to large-scale workpiece, not only convenient but also safety.Existing trailer generally includes trailer body and four rotating feets, and during transportation, four feet located lateral are in four bights of trailer body; When parking, four feets can turn to vertical direction and trailer are supported, and can guarantee that through the setting of feet large-scale workpiece puts steadily.The supporting base that existing feet generally includes the feet body and is fixedly connected on feet body bottom; Because supporting base can not be swung; Therefore this feet can only be positioned on the ground of level, and when needs were placed on the slope, existing feet just can't be placed steadily.
The utility model content
The utility model provides a kind of placement pulsation-free trailer, and supporting base and ground keeping parallelism can swung and make to its supporting base arbitrarily, and its purpose is to overcome the problems referred to above that prior art exists.
The technical scheme of the utility model is following:
A kind of placement pulsation-free trailer; Comprise trailer body and the feet that is rotationally connected with trailer body four bights; Said feet comprises feet body, ball and socket and the supporting base that can swingingly be sheathed on ball and socket arbitrarily, and said ball and socket is fixedly connected on the bottom of feet body.
As the improvement of the utility model, said supporting base is made up of upper and lower support portion, and the middle part of last support portion is provided with the spherical through hole that cooperates with ball and socket; The middle part of following support portion is provided with the ball recess that cooperates with ball and socket.
Can know by above-mentioned description the utility model; Compare with prior art; The advantage of the utility model is: supporting base is sheathed on the ball and socket, and it can swing arbitrarily and make it parallel to the ground according to ground-surface angle of inclination, thereby guarantees the steady placement of workpiece on the trailer.
Description of drawings
Fig. 1 is the structural representation of trailer.
Fig. 2 is the cross-sectional view of feet.
The specific embodiment
The specific embodiment of the utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, a kind of trailer of being convenient to regulate height, four feets 2 that comprise trailer body 1 and be positioned at trailer body 1 four bights, during transportation, feet 2 can turn to laterally and is positioned at the side of trailer body 1; When parking, feet 2 ground that are supported in as shown in Figure 1.
With reference to Fig. 2, feet 2 comprises feet body, ball and socket 8 and the supporting base 7 that can swingingly be sheathed on ball and socket 8 arbitrarily simultaneously, and ball and socket 8 is fixedly connected on the bottom of feet body.Supporting base 7 is made up of upper and lower support portion 71,72, and the middle part of last support portion 71 is provided with the spherical through hole that cooperates with ball and socket 8; The middle part of following support portion 72 is provided with the ball recess that cooperates with ball and socket 8.Ball and socket 8 can be swung arbitrarily in supporting base 7, and it can swing arbitrarily and make it parallel to the ground according to ground-surface angle of inclination, thereby guarantees the steady placement of workpiece on the trailer.
In addition; The movable axis 5 that the feet body comprises locating bush 3, the screw mandrel 4 of lower ending opening and is positioned at locating bush 3 and can slides with respect to locating bush 3; The middle part of movable axis 5 is provided with negative thread, and the bottom of movable axis 5 is welded with pole 6, and screw mandrel 4 is formed by the rotation section 41 of upper end and with rotation section 41 integrated threaded shank 42; Rotation section 41 is cuboid (also can be arranged to hexagon as required); Its bore is greater than the bore of threaded shank 42, the 41 rotating tops that are positioned locating bush 3, rotation section, and threaded shank 42 stretches into movable axis and is connected with screw-internal thread fit.Only need during use rotation section 41 rotations, movable axis 5 just can upper and lower motion in locating bush 3.
Improvement as the utility model; The said above-mentioned specific embodiment that is merely the utility model; But the design concept of the utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
