Abstract
The utility model relates to a jack frame. The jack frame comprises a supporting frame, wherein a jack is placed on the supporting frame; idler wheels are mounted at two ends of the supporting frame; handles are welded on two sides of the supporting frame; axles are arranged in the idler wheels; shaft brackets are fixed on both sides of the idler wheels; springs are fixed inside the shaft brackets, and can jack up the supporting frame from the ground when the jack is free from load or the load is only for supporting; the both ends of the axles are placed inside the shaft brackets; the axles are located under the springs to resist against the idler wheels to get down, so as to jack up the supporting frame. The jack frame provided by the utility model is reasonable in structural design, low in cost and convenient to use, enables a user to move the jack conveniently, saves labor force, improves working efficiency, improves the supporting conditions at the lower part of the jack, and increases the stability of the jack when supporting, because of the placement that the supporting frame is cushioned under the jack.
Description
Technical field
The utility model relates to docking facility technical field, specifically a kind of jack stand.
Background technology
Jack is very general in maintenance or lifting application in machine equipments, but because general jack quality is larger, when moving or carrying jack, quite require great effort, in the time of maintenance or some equipment of lifting, often need a more than jack, this just makes to carry jack and becomes more difficult.
The jack stand spininess with wheel having is in the market to an only jack use, and in the time that required jack quantity is more, described existing jack stand will can not meet operating needs.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of jack stand.
The utility model solves its technical matters and realizes by the following technical solutions:
A kind of jack stand, comprises bracing frame, is placed with jack on support frame as described above, and the two ends of bracing frame are provided with roller, and the both sides of bracing frame are welded with handle; In described roller, be provided with wheel shaft, and the two ends of wheel shaft are provided with block, the both sides of roller are fixed with pedestal; Described pedestal inside is fixed with spring, and spring can be only, while supporting the jack of use, bracing frame to be pushed up overhead there is no load or load; The two ends of described wheel shaft are placed in the inside of pedestal, and wheel shaft is positioned at the below of spring, downward to prop up roller, thereby by bracing frame jack-up.
Described roller is at least two, and is symmetrically distributed in the two ends of bracing frame.
Described jack is at least one.
Described handle is at least two, and is welded on the both sides of bracing frame, conveniently under the condition without larger friction force, promotes bracing frame at bracing frame and ground and moves.
The compressible length of described spring is greater than the lower end of roller and the vertical distance of bracing frame bottom surface, when there being appropriate load on bracing frame, and when load does not comprise the jack that supports use, described load the lower end of roller can be depressed into bracing frame bottom surface at grade, now, bracing frame bottom surface contacts with ground, friction force between bracing frame bottom surface and ground also will increase, ensured in use, bracing frame can arbitrarily not move, thereby has ensured the stability that jack supports.
The beneficial effects of the utility model are: the utlity model has reasonable in design, the advantage such as with low cost, easy to use, facilitate user to carry jack, save muscle power, improve work efficiency, and the form of putting by bracing frame pad below jack, improve the supporting condition of jack bottom, increased the stability of jack in the time supporting.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is birds-eye view of the present utility model;
Fig. 2 is the A-A echelon sectional view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 2.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 to Figure 3, a kind of jack stand, comprises bracing frame 1, is placed with jack 3 on support frame as described above 1, and the two ends of bracing frame 1 are provided with roller 2, and the both sides of bracing frame 1 are welded with handle 4; In described roller 2, be provided with wheel shaft 201, and the two ends of wheel shaft are provided with block 204, the both sides of roller 2 are fixed with pedestal 202; Described pedestal 202 inside are fixed with spring 203, and spring 203 can be only, while supporting the jack 3 of use, bracing frame 1 to be pushed up overhead there is no load or load; The two ends of described wheel shaft 201 are placed in the inside of pedestal 202, and wheel shaft is positioned at the below of spring 203, downward to prop up roller 2, thereby by bracing frame 1 jack-up.
Described roller 2 is at least two, and is symmetrically distributed in the two ends of bracing frame 1.
Described jack 3 is at least one.
Described handle 4 is at least two, and is welded on the both sides of bracing frame 1, conveniently under bracing frame 1 and the condition of ground without larger friction force, promotes bracing frame 1 and moves.
The compressible length of described spring 203 is greater than the lower end of roller 2 and the vertical distance of bracing frame 1 bottom surface, when there being appropriate load on bracing frame 1, and when load does not comprise the jack 3 that supports use, described load bracing frame 1 bottom surface can be depressed into the lower end of roller 2 at grade, now, bracing frame 1 bottom surface contacts with ground, friction force between bracing frame 1 bottom surface and ground also will increase, ensure in use, bracing frame 1 can arbitrarily not move, thereby has ensured the stability that jack 3 supports.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
