Abstract
The utility model discloses a high jump stand. The high jump stand comprises a base and a stand column. A gradienter is arranged on the base. The base can be adjusted to be horizontal by adjusting the height of legs of the base. The stand column is marked with scale lines and sleeved with a sliding sleeve made of soft silica gel. The sliding sleeve is in loose fit with the stand column so as to move in the vertical direction conveniently and is provided with a rod support used for supporting a cross rod. A lever is arranged on one side of the sliding sleeve, provided with a magnetic pole and a friction block and connected with the sliding sleeve through a pin shaft. The sliding sleeve is further provided with a fixed magnetic pole. Both the fixed magnetic pole and the lever magnetic pole are powerful magnets. The high jump stand is characterized in that the high jump stand is freely adjusted in the vertical direction by locking the sliding sleeve through magnetic force. Compared with the prior art, the high jump stand is simple in structure, ingenious in design, high in practicality and lower in manufacturing cost.
Description
Technical field
The utility model relates to a kind of sports equipment, specifically refers to be used for shelving in high jump the jumping stand of cross bar.
Background technology
When jumping stand is high jump, for the support of support rail, owing to often needing to regulate height in high jump, thereby good jumping stand needs to regulate height; On the other hand, high jumper particularly beginner may knock column or sliding sleeve is injured, thereby the security of jumping stand has also been proposed to higher requirement.
The jumping stand using is at present mostly metal material, comprise: base, vertical columns, mobile column, vertical columns is fixedly mounted on base, on vertical columns, be provided with upper connector and lower connector, on lower connector and vertical columns, be provided with set lever, mobile column activity wears in upper connector, and the lower end of mobile column is fixed on lower connector.Its using method is: in the time need to adjusting the height of mobile column, unscrew set lever, then regulate up or down lower connector, drive mobile column to move or move down in upper connector, be adjusted to after desired height, tighten again set lever, by lower connector, mobile column and vertical columns fixed bit.The shortcoming of the jumping stand of said structure is: coordinating between vertical columns and mobile column mainly relies on upper and lower connector, and its fit clearance is large, and structure is loaded down with trivial details; In addition, upper and lower connector is metal material, has corner angle, once sportsman knocks, injured meeting is very serious.
On this basis, Chinese patent CN102114317A discloses a kind of jumping stand that adopts motor lifting, obviously, adopts motor to drive that not only cost is high, and powered restriction, very inconvenient.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of regulate height and the high jumping stand of safety coefficient simple in structure, convenient are provided.
For overcoming the deficiencies in the prior art, the utility model is taked following technical scheme:
A kind of jumping stand, comprises base and column, it is characterized in that: base is provided with level meter that the pin adjustable-height of base can be horizontal by adjusting base; Column is carved with scale and cover has sliding sleeve, sliding sleeve is that soft silica gel is made, sliding sleeve and column are loose fit, are convenient to move up and down, and sliding sleeve is provided with lever bracket, for support rail, sliding sleeve one side has lever, has magnetic pole and brake pad on lever, and lever is by bearing pin and sliding sleeve link, on sliding sleeve, be also provided with fixed magnetic pole, fixed magnetic pole and lever magnetic pole are strong magnets.
When normal use, the magnetic pole on fixed magnetic pole and lever on sliding sleeve attracts each other, and by lever pressing friction piece, brake pad compresses column, reaches the effect of locking and fixing sliding sleeve.In the time that need regulate height, the lever upper end of holding with a firm grip presses to sliding sleeve, overcomes magnetic force and just brake pad can be unclamped to column, can move up and down flexibly like this, realizes highly and regulating.
Feature of the present utility model is that the easy on and off that adopts magnetic locking sliding sleeve to realize jumping stand regulates, compared with prior art, of the present utility model simple in structure, designs ingeniously, practical, and cost and cost are also lower; The utility model is also provided with screw and the level meter of adjusting level on base, makes precision higher; Sliding sleeve of the present utility model adopts soft silica gel and removes corner angle as far as possible, has improved security.
Accompanying drawing explanation
Fig. 1 is planar structure schematic diagram of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
In figure, each label represents:
1, base; 2, column; 3, sliding sleeve; 4, brake pad; 5, bearing pin; 6, fixed magnetic pole; 7, lever magnetic pole; 8, lever; 9, lever bracket.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further illustrated.
Jumping stand as depicted in figs. 1 and 2, comprises base 1 and column 2, and base 1 is provided with level meter, the pin adjustable-height of base 1, and adjusting base is horizontal; Column 2 is carved with scale and cover has sliding sleeve 3, sliding sleeve 3 is made for soft silica gel, sliding sleeve 3 and column 2 are loose fit, are convenient to move up and down, and sliding sleeve 3 is provided with lever bracket 9, for support rail, sliding sleeve 3 one sides have lever 8, have magnetic pole 7 and brake pad 4 on lever 8, and lever links by bearing pin 5 and sliding sleeve 3, on sliding sleeve 3, be also provided with fixed magnetic pole 6, fixed magnetic pole 6 is strong magnets with lever magnetic pole 7.
When normal use, the magnetic pole 7 on fixed magnetic pole 6 and lever on sliding sleeve 3 attracts each other, and by lever 8 pressing friction pieces 4, brake pad 4 compresses column 2, reaches the effect of locking and fixing sliding sleeve 3.In the time that need regulate height, lever 8 upper ends of holding with a firm grip press to sliding sleeve 3, overcome magnetic force and just brake pad 4 can be unclamped to column, can move up and down flexibly like this, realize highly and regulating.
Above-mentioned is preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
