Abstract
A jack comprises a jack body, and is characterized in that the jack body further comprises a base with area larger than projection area of the jack body, a support part, a worm gear and a worm are disposed on the base, the worm gear matches with the worm, the worm gear is fixedly connected with a connecting table, the connecting table is provided with a protruded key, a groove is disposed at the bottom of the jack body, and the protruded key is fittingly connected with the groove. The jack can be used in environments with various inclination angles.
Description
Technical field
The utility model relates to a kind of jack, but the jack at the various environments for use of particularly a kind of flexible adaptation angle of inclination.
Background technology
Traditional jack can only be used for the support of vertical and horizontal direction, and tends to occur supporting instability, problems such as jack overturning owing to the jack bottom is less relatively for the weight support at angle of inclination.
Therefore, need a kind of jack that can the various environments for use of flexible adaptation angle of inclination of invention to address the above problem.
Summary of the invention
The jack that provides the various environments for use of a kind of flexible adaptation angle of inclination but the purpose of this utility model is to solve the deficiencies in the prior art part.
The purpose of this utility model can realize by following technical measures: a kind of jack, comprise the jack body, described jack also includes the base greater than jack body area of conter, described base is provided with the worm gear and the worm screw of strut member, cooperation, described worm gear is fixedly connected with one and connects platform, described connection platform is provided with the projection key, and described jack body bottom is provided with groove, and described projection key is connected with described groove fit.Described jack body can be oil jack or other jacks.
Base is the basic components that support jack, because pedestal and contact area of ground are bigger, therefore can prevent translating into of jack.Worm and gear adopts gauge member, is used to realize the multi-angle adjusting of jack.
As the preferred implementation of the utility model jack, described projection key is a cylindrical keys.Cylindrical keys and groove fit are used for jack rotation in the horizontal direction.
The utility model the bottom of jack body cooperate one can vertical surface in rotatable connection platform, so just can support to realize bevelled as the bottom of jack body by firm inclined base, the rotation that connects platform simultaneously can also realize the support of jack body differing tilt angles, has increased the range of use of jack.The rotation that connects platform in the utility model realizes by worm gear, worm gearing, worm gear is fixed on the same S. A. by keyway with the connection platform that is connected the jack body, when worm screw drives the worm gear rotation, also can drive the jack rotation simultaneously like this.Adopt worm gear, worm mechanism to realize that the advantage of pedestal rotation is: worm screw, worm gear belong to the vertical direction transmission, compare this mode of employing with the transmission device of coaxial direction and regulate the restriction that the rotation of pedestal more is not subject to working environment; And worm gear, worm drive also have the characteristics of self-locking, therefore can guarantee the stability when jack support weight.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of an embodiment of the utility model jack.
The specific embodiment
For making the utility model easier to understand, will further set forth specific embodiment of the utility model below.
Embodiment 1
As shown in Figure 1, a kind of jack 100 of the present utility model, comprise jack body 10, described jack 100 also includes the base 20 greater than jack body 10 areas of conter, worm gear 40 and worm screw 42 that described base 20 is provided with strut member 30, cooperates, described worm gear 40 is fixedly connected with one and connects platform 50, described connection platform 50 is provided with projection key 52, described jack body 10 bottoms are provided with groove 60, and described projection key 52 is connected with described groove 60 (projection key 52 does not show in the drawings with groove 60).Described projection key 52 is a cylindrical keys.
Last institute should be noted that; above embodiment is only in order to the explanation the technical solution of the utility model but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
Claims (2)
1. jack, comprise the jack body, it is characterized in that: described jack also includes the base greater than jack body area of conter, described base is provided with the worm gear and the worm screw of strut member, cooperation, described worm gear is fixedly connected with one and connects platform, described connection platform is provided with the projection key, and described jack body bottom is provided with groove, and described projection key is connected with described groove fit.
