Abstract
The utility model discloses a plugging type valve stem structure for fixing a jack handle on a lifting handle. The valve stem structure comprises a handle, a lifting handle, a lifting handle thread hole and a valve stem, wherein the interior of the lifting handle thread hole is provided with the plugging type valve stem structure, the valve steam is sheathed with a spring, the outer side of the spring is provided with a valve sleeve, one end of the valve stem is inserted into a valve sleeve hole, the outer side of the other end of the valve stem is provided with a pull button, the pull button is provided with a pull button hole, and the valve stem is inserted into the pull button hole. The plugging type valve stem structure has the advantages that the resetting force of a compressive spring is used for controlling the extending and reaction of the valve stem, and then the handle is limited and prevented from being plugged out of the lifting handle; when the handle is installed and detached, the convenience and the rapidity are realized, and a special wrench is not needed to unscrew a lifting handle bolt.
Description
technical field
The utility model relates to jack, is specifically related to a kind of jack handle is fixed on to the plug type stem structure on lift.
Background technique
The structure of the fixed handle of traditional jack is that the lift bolt by being located on lift is connected with lift, so will take away handle, must first with spanner, lift bolt be twisted off, time-consuming and trouble.
Model utility content
Technical problem to be solved in the utility model is, provide a kind of jack handle is fixed on to the plug type stem structure on lift, the stem structure of this plug type utilizes the reposition force of Compress Spring to control the flexible of valve rod, finally limits and prevents that handle from extracting from lift.When this product installation and removal handle, convenient and swift, without remove to turn on lift bolt with special spanner.
For solving the problems of the technologies described above, the utility model provides is a kind ofly fixed on the plug type stem structure on lift by jack handle, comprises handle, lift, lift tapped hole, in described lift tapped hole, be provided with plug type stem structure, described plug type stem structure comprises valve rod, and on valve rod, cover has spring, and spring outside is provided with valve pocket, valve pocket hole is injected in one end of described valve rod, the other end outside of valve rod is provided with tension-torsion, and described tension-torsion is provided with tension-torsion hole, and valve rod is plugged in tension-torsion hole.
As improvement, the outside interference fit of described tension-torsion hole and valve rod.
Adopt after above structure, plug type stem structure of the present utility model compared with prior art, has the following advantages: the stem structure of this plug type utilizes the reposition force of Compress Spring to control the flexible of valve rod, finally limits and prevents that handle from extracting from lift.When this product installation and removal handle, convenient and swift, without remove to turn on lift bolt with special spanner.
Working principle of the present utility model: when pulling with hand tension-torsion, valve rod also moves thereupon outward, handle is not just subject to the restriction of the front-end face of valve rod so, just handle can be taken away in lift hole.In handle inserts lift hole, decontrol tension-torsion, handle is just limited by valve rod, thus handle is just fixed in lift hole.
Accompanying drawing explanation
Fig. 1 is that the utility model is for a kind of structural representation that jack handle is fixed on to the plug type stem structure on lift.
Wherein: 1, handle, 2, lift, 3, lift tapped hole, 4, valve rod, 5, spring, 6, valve pocket, 7, tension-torsion, 8, tension-torsion hole.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, jack handle is fixed on the plug type stem structure on lift, comprises handle 1, lift 2, lift tapped hole 3, in described lift tapped hole, be provided with plug type stem structure, described plug type stem structure comprises valve rod 4, and on valve rod, cover has spring 5, and spring outside is provided with valve pocket 6, valve pocket hole is injected in one end of described valve rod, the other end outside of valve rod is provided with tension-torsion 7, and described tension-torsion is provided with tension-torsion hole 8, and valve rod is plugged in tension-torsion hole.The outside interference fit of described tension-torsion hole and valve rod.
During actual use, when pulling with hand tension-torsion, valve rod also moves thereupon outward, and handle is not just subject to the restriction of the front-end face of valve rod so, just handle can be taken away in lift hole.In handle inserts lift hole, decontrol tension-torsion, handle is just limited by valve rod, thus handle is just fixed in lift hole.
The stem structure of this plug type utilizes the reposition force of Compress Spring to control the flexible of valve rod, finally limits and prevents that handle from extracting from lift.When this product installation and removal handle, convenient and swift, without remove to turn on lift bolt with special spanner.
Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technological scheme that claim records.
Claims (2)
1. one kind is fixed on the plug type stem structure on lift by jack handle, comprise handle (1), lift (2), lift tapped hole (3), it is characterized in that, in described lift tapped hole, be provided with plug type stem structure, described plug type stem structure comprises valve rod (4), on valve rod, cover has spring (5), spring outside is provided with valve pocket (6), valve pocket hole is injected in one end of described valve rod, the other end outside of valve rod is provided with tension-torsion (7), and described tension-torsion is provided with tension-torsion hole (8), and valve rod is plugged in tension-torsion hole.
2. according to claim 1ly for a kind of, jack handle is fixed on to the plug type stem structure on lift, it is characterized in that the outside interference fit of described tension-torsion hole and valve rod.
