ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a jack with enclosing (or cover) plates which is especially suited for enclosing the supporting plates at two sides of a four wheel jack and the pump of the jack. The enclosing plates can have any desired shape or colors so that the outlook of the jack is vivid and various. By the enclosing the jack with the enclosing plates, painting for the related shielding components by baking or injection can be omitted.
BACKGROUND OF THE INVENTION
The prior art jack primarily includes a hydraulic cylinder, a pump set, a lifting arm, a top disk, and supporting plates at two sides. Each of four ends at the bottom of the supporting plates is installed with a respective rolling wheel. However, such kind of jack has a dull and fixed outlook. Moreover, all the components are protruded. Thus, the components must be made to match with each other by the work of painting by baking or injection for beautifying. However, only the exposed portions are colored, and thus the all structure still appears a dull outlook without any attraction to users.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a jack with enclosing (or cover) plates. The supporting plates at two sides of the jack and the hollow portion of the pump are enclosed by the enclosing (or cover) plates. Thus, the jack has a vivid outlook and is colored without confining by the predetermined shape. The exposed components of the jack is beautified. By the jack with the enclosing (or cover) the enclosing the enclosing plates, painting for the related shielding components by baking or injection can be omitted.
Another object of the present invention is to provide a jack with enclosing (or cover) plates. The cover or enclosing plate can be secured by tenons or screwing lock. Thus, the present invention has a simple structure and can be assembled easily.
A further object of the present invention is to provide a jack with enclosing or cover plates, further comprising a pump enclosing plate for being connected with the supporter enclosing or cover plate at two sides. One or more engaging holes are formed at the upper end of the supporter enclosing or cover plates, and a hollow hole is formed in front section at each side of the pump enclosing plate for covering the two supporter enclosing plates, i.e. at a position in the jack pump with respect to a release valve so that after covering, part of the pump set and the release valve will protrude out. The two sides of the pump enclosing or cover plates are installed with respective engaging piece for inserting into the engaging hole of the supporting enclosing plate so as to be combined tightly.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
