Description
Technical field
The present invention relates to a kind of sports or the used utensil of competing, refer more particularly to the jumping stand that is used for shelving cross bar in the high jump.
Background technology
The structure of present employed jumping stand is referring to shown in Figure 1, comprise: base 1, vertical columns 2, mobile column 5, vertical columns 2 is fixedly mounted on the base 1, vertical columns 2 is provided with upper connector 6 and following connector 4, following connector 4 and vertical columns 2 are provided with set lever 3, mobile column 5 activities wear in the upper connector 6, and the lower end of mobile column 5 is fixed on down on the connector 4.Its using method is: when needs are adjusted the height of mobile column 5, unscrew set lever 3, regulate connector 4 down then up or down, driving mobile column 5 moves or moves down in upper connector 6, after transferring to required height, tighten set lever 3 again, will descend connector 4, mobile column 5 to fix with vertical columns 2.The shortcoming of the jumping stand of said structure is: operate cumbersome, and the location inaccuracy.
Summary of the invention
Technical problem to be solved by this invention is: a kind of simple to operate, location jumping stand of using of convenient accurate high jump will be provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the jumping stand that high jump is used, comprise: base, vertical columns, mobile column, vertical columns is fixedly mounted on the base, be characterized in: in the inner chamber of vertical columns, also be provided with screw mandrel, the top movable of screw mandrel is arranged in the top chock that is installed in the vertical columns, the lower end of screw mandrel is movably arranged in the step that is installed in the vertical columns; an end of rocking handle also is movably arranged in the top chock after stretching into vertical columns, and the bevel gear that a parafacies interworking is closed is separately positioned on the upper end of screw mandrel and an end of rocking handle; Also threaded engagement has the screw mandrel cover on screw mandrel, also offers axial chute on the sidewall of vertical columns, and connecting bolt is arranged in the chute and with mobile column fixedlys connected with the screw mandrel cover.
Be slidingly matched mutually by the dovetail groove type slide construction between above-mentioned mobile column and the vertical columns.
Above-mentioned dovetail groove type slide construction is specially: vertical columns is provided with dovetail groove, and mobile column is provided with the dovetail projection that matches with dovetail groove.
The invention has the beneficial effects as follows: in use easy to operate as long as shake the height that handle just can be regulated mobile column, locate also more accurate.
Description of drawings
Fig. 1 is the structural representation of the jumping stand described in the background technology;
Fig. 2 is the structural representation of jumping stand of the present invention;
Fig. 3 is the C part structure for amplifying schematic diagram among Fig. 2;
Fig. 4 is the A-A cross-sectional view among Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 2, Fig. 3, shown in Figure 4, the jumping stand that high jump described in the present embodiment is used, comprise: base 1, vertical columns 2, mobile column 3, vertical columns 2 is fixedly mounted on the base 1, in the inner chamber of vertical columns 2, also be provided with screw mandrel 5, the top movable of screw mandrel 5 is arranged in the top chock 7 that is installed in the vertical columns 2, the lower end of screw mandrel 5 is movably arranged in the step 4 that is installed in the vertical columns 2; end of rocking handle 9 also is movably arranged in the top chock 7 after stretching into vertical columns 2, and the bevel gear 8 that a parafacies interworking is closed is separately positioned on the upper end of screw mandrel 5 and an end of rocking handle 9; Also threaded engagement has screw mandrel cover 6 on screw mandrel 5, also offers axial chute on the sidewall of vertical columns 2, and connecting bolt 10 is arranged in the chute and mobile column 3 and screw mandrel are overlapped 6 fixedlys connected.In the present embodiment, be slidingly matched mutually by the dovetail groove type slide construction between described mobile column 3 and the vertical columns 2, its concrete structure is: vertical columns 2 is provided with dovetail groove, mobile column 3 is provided with the dovetail projection 31 that matches with dovetail groove, be slidingly matched mutually by the dovetail groove type slide construction between mobile column 3 and the vertical columns 2, it is simple in structure, cooperation is tight relatively and slide flexible.
The using method of above-mentioned jumping stand is: when needs are adjusted the height of mobile column 3, only need to shake rocking handle 9; bevel gear 8 that rocking handle 9 closes by a parafacies interworking drives screw mandrel 5 rotations; make screw mandrel cover 6 on screw mandrel 5, move up or down; screw mandrel cover 6 drives mobile column 3 by connecting bolt 10 again and moves up or down, and gets final product up to transferring to desired height to a certain direction.
In sum,, easy to operate as long as shake the height that rocking handle 9 just can be regulated mobile column 3, locate also more accurate.
