Description

Cardan wheel

Technical field

The utility model relates to a kind of cardan wheel.

Background technology

Existing cardan wheel comprises and lathe bonded assembly permanent seat, supporting support body, pulley and the bearing pin that is connected pulley, though adopt the cardan wheel of this structure to have the advantage of mobile device effortlessly, the levelness of inconvenient conditioning equipment.

Summary of the invention

The utility model has overcome the defective on the prior art, and a kind of mobile device effortlessly is provided, and can make things convenient for the cardan wheel of the levelness of conditioning equipment again.

The utility model comprises and lathe bonded assembly permanent seat, supporting support body, pulley and the bearing pin that is connected pulley that the below of supporting support body is provided with guide rail, and it is built-in with support foot, in the described support foot cavity is arranged, and its internal fixation has nut; Center shaft on the described permanent seat is provided with through hole vertically, and the bottom of this through hole is provided with the bulge loop toward internal projection; The double-screw bolt of bolt is connected with nut, and the nut top central authorities of bolt are provided with projection, can stretch in the through hole in the permanent seat, and the end face of described projection is equipped with by the fixing cover plate of screw, and the internal diameter of this cover plate is more bigger than the bulge loop internal diameter of through hole bottom.

As a kind of improvement of the present utility model, described nut is the external tooth wheel shape.

The utility model is owing to adopt below the supporting support body support foot is housed, the structure that the stroke of this support foot can be regulated by bolt, thereby can be laborsaving, can make things convenient for the levelness of conditioning equipment again.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1～cardan wheel shown in Figure 7, comprise and lathe bonded assembly permanent seat 1, supporting support body 2, pulley 3 and the bearing pin 4 that is connected pulley 3 that the below of supporting support body 2 is provided with guide rail 21, it is built-in with support foot 22, in the described support foot 22 cavity is arranged, its internal fixation has nut 23; Center shaft 11 on the described permanent seat 1 is provided with through hole 12 vertically, and the bottom of this through hole 12 is provided with the bulge loop 13 toward internal projection; The double-screw bolt 51 of bolt 5 is connected with nut 23, the nut 52 top central authorities of bolt 5 are provided with projection 53, can stretch in the through hole 12 in the permanent seat 1, the end face of described projection 53 is equipped with by the fixing cover plate 6 of screw, and the internal diameter of this cover plate 6 is more bigger than bulge loop 13 internal diameters of through hole 12 bottoms.

The utility model is to use like this: load onto several cardan wheels in the bottom of equipment earlier, before needs were moved equipment, conter clockwise turned the nut 52 of bolt 5, and support foot 22 is lifted from ground, this moment, cardan wheel of the present utility model and existing cardan wheel similarly can be laborsaving, conveniently moved equipment; Equipment through moving will be readjusted its levelness, need only cw turns the nut 52 of bolt 5 this moment, and the support foot of each cardan wheel is stretched out, and the overhang of each support foot is adjusted on the ground of directly conflicting again respectively, can adjust the levelness of equipment easily.

As a kind of improvement of the present utility model, described nut 52 is the external tooth wheel shape, can make things convenient for the user to regulate bolt 5 like this, is support foot with each cardan wheel when stretching out especially, because it is big to establish weight, adopts this structure can make things convenient for user's application of force.
