Abstract
The utility model discloses a combined type jack which comprises a scissor-type jack and is characterized in that a support table of the scissor-type jack is provided with at least one support pipe, an outer screw is integrally arranged at the lower end of the support pipe, the support table is in threaded connection with the outer screw, and an inner screw hole which is in threaded connection with the outer screw is arranged at the upper end of the support pipe. The combined type jack has the advantages that due to the fact that the support table of the scissor-type jack is provided with at least one support pipe, when the jacking height of the scissor-type jack is not enough, the jacking height of the jack is increased by installation of the support pipe on the support table. Due to the fact that an adjusting seat is hinged on a base of the jack, an adjusting bolt and the base are in threaded connection, and the lower end of the adjusting bolt is abutted against the adjusting seat, when the scissor-type jack is used in inclined sites of the ground, an included angle between the base and the adjusting seat is adjusted through the adjusting bolt so as to enable the support table of the jack to be in a horizontal plane. Therefore, the whole combined type jack is multifunctional and application situations of the combined type jack are relatively wide.
Description
Technical field
The utility model relates to a kind of jack, relates in particular to a kind of compound type jack.
Background technology
Jack is support expansion tool commonly used in daily life and some disaster reliefs (such as traffic accident, earthquake, landslide etc.), and our common jack mainly contains hydraulic jack, scissor-like jack etc. at present.Scissor-like jack mainly is to utilize the rotating drive strut bar of screw mandrel to erect or descend to realize its support function, but present scissor-like jack, and its structure, function are all more single, therefore also cause its application scenario to be restricted.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of function is many, application scenario compound type jack widely.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of compound type jack, comprise scissor-like jack, be provided with at least one support tube on the brace table of described scissor-like jack, the lower end of described support tube has been wholely set external screw rod, described brace table and described external screw rod bolt, the upper end of described support tube be provided with for the inner bolt hole of described external screw rod bolt.
Described scissor-like jack comprises base, brace table, screw rod, the first contiguous block, the second contiguous block and mutually surround the first strut bar of a rhombus, the second strut bar, the 3rd strut bar and the 4th strut bar, the lower end of described the first strut bar and the second strut bar is coupling on described base, the upper shaft of described the 3rd strut bar and the 4th strut bar is connected on the described brace table, the lower end of the upper end of described the first strut bar and described the 4th strut bar is coupling respectively on described the first contiguous block, the lower end of the upper end of described the second strut bar and described the 3rd strut bar is coupling respectively on described the second contiguous block, the optical axis of described screw rod partly passes described the first contiguous block, be provided with removable pin on described the first contiguous block, described removable pin radially passes the optical axis part of described the first contiguous block and screw rod, be provided with through hole on described the second contiguous block, described screw flight partly passes the through hole on described the second contiguous block, be bolted with drive nut on the described screw rod, described drive nut is positioned at the outside of described the second contiguous block.
Be hinged with adjustment seat on the described base, be provided with the adjusting bolt of vertical placement on the described base, described adjusting bolt and described base bolt and lower end withstand on the described adjustment seat.
Described support tube is at least two and vertically stack.
Compared with prior art, the utility model has the advantages that owing to be provided with at least one support tube on the brace table of scissor-like jack, when the top lifting height of scissor-like jack is inadequate, can be by at brace table the top lifting height that support tube increases jack being installed; Again owing to be hinged with adjustment seat on the base of jack, adjusting bolt and base bolt and lower end withstand on the adjustment seat, when when the occasion of some terrain slopes is used, can come angle between adjusting base and the adjustment seat by adjusting bolt, make the supporting platform of jack on horizontal surface; Therefore, whole apparatus function is more, simultaneously also so that its application scenario is more extensive.
