Legend description:

1. a spring cylinder; 11. a spring rod body; 12. an extension rod; 2. a movable end cover; 21. an external thread; 22. a lower open groove; 3. winding a ring; 31. a mounting hole; 32. and (5) an internal thread.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a nitrogen spring with adjustable, includes spring cylinder body 1 and spring cylinder body 1 top opening part sliding connection's spring body of rod 11, and spring body of rod 11 top both sides vertical direction is provided with extension pole 12, and spring body of rod 11 top cover is equipped with movable end cover 2, and movable end cover 2 outside closes soon and is connected with around ring 3, around ring 3 and extension pole 12 top butt.

Wherein, the outside cover of the spring body of rod 11 in the nitrogen spring is equipped with movable end cover 2, movable end cover 2 is pegged graft through lower opening recess 22 and extension pole 12 department, because the degree of depth of lower opening recess 22 is after movable end cover 2 deflects certain angle, the degree of depth of lower opening recess 22 produces the change, in order that when the degree of depth adjustment of different lower opening recess 22 department, the grafting degree of depth between movable end cover 2 and the spring body of rod 11 receives the adjustment, make movable end cover 2 when the grafting degree of depth adjustment with the spring body of rod 11, the height when the adjustment nitrogen spring of correspondence is whole installs, in order to be applicable to the adjustment demand of the vertical direction interval deviation that produces when the nitrogen spring installs.
