Abstract
The utility model provides a lockable gas traction spring whose rebound portion can be controlled after being tensed. The spring comprises a cylinder body, a guiding seal sleeve, a rear plug and a piston rod, wherein the guiding seal sleeve is fixed on the front end of the cylinder body, the rear plug is fixed on the tail end, a fixing baffle plug is fixed in the cylinder body, the front side and the rear side of the fixing baffle plug are respectively provided with a piston and a valve body piston, and the piston and the valve body piston are connected through a piston rod. The lockable gas traction spring is characterized in that the baffle plug is arranged and fixed in the cylinder body, nitrogen and liquid oil are respectively charged in the front cavity and the rear cavity of the cylinder body, liquid oil enters between the piston of the valve body and the rear plug after being tensed, and since liquid oil takes rigidity and can not be pressed, thereby reaching the effect that the rebound portion of the piston rod can be controlled after withdrawing external force, and achieving the locking of the gas traction spring.
Description
Technical field
The utility model relates to a kind of air spring, particularly a kind of lockable pulling force air spring.
Background technique
Air spring is widely used in medical equipment, automobile, furniture, Weaving device, processing industry, and wherein the kind of pulling force air spring is less, remove the external force of stretching pulling force air spring after, air spring promptly resets, and can't lock it, has limited its using scope.
The model utility content
The technical problems to be solved in the utility model provides a kind of controlled lockable pulling force air spring of back resilient portion that stretches.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of lockable pulling force air spring, comprise cylinder body, pilot seal cover, stifled, the piston rod in back, the front end of described cylinder body is fixed with the pilot seal cover, it is stifled that end is fixed with the back, its innovative point is: described cylinder body internal fixation has fixing every plug, and described fixing every plug front and back side is respectively equipped with piston and valve body piston, and described piston is connected by piston rod with the valve body piston.
Further, described fixing ante-chamber every plug is filled with nitrogen, and back cavity is filled with liquid oils.
Further, in the described piston rod starting bar is housed, described starting bar is fixedlyed connected with the needle of valve body piston.
Further, be connected with Returnning spring between described piston rod and the starting bar.
Advantage of the present utility model is: install additional fixing every plug in the cylinder body, the chamber fills nitrogen and liquid oils respectively before and after it, the back liquid oils that stretches enters between valve body piston and back the blocking up, because it is incompressible that liquid oils is rigidity, reach and remove the controlled effect of external force back piston bar resilient portion, realized the locking of pulling force air spring.
Description of drawings
Figure is the structural representation of lockable pulling force air spring of the present utility model.
Embodiment
As shown in the figure, comprise that cylinder body 1, pilot seal cover 2, back are stifled 3, fixing every plug 4, piston 5, valve body piston 6, piston rod 7, starting bar 8, Returnning spring 9.
The front end of above-mentioned cylinder body 1 is fixed with pilot seal cover 2, end is connected with back stifled 3, the chamber internal fixation is connected with fixing every plug 4, be divided into front/back cavity by fixing every plug 4 inner chambers with cylinder body 1, be filled with nitrogen 10 in ante-chamber, back cavity is filled with liquid oils 11, and piston 5 and valve body piston 6 are located at fixing in the front/back cavity of plug 4 both sides respectively, piston 5 all is connected with piston rod 7 with valve body piston 6, realizes both interlocks.Be connected with starting bar 8 in piston rod 7, described starting bar 8 is connected as a single entity with the needle 12 of valve body piston 6,
Because lockable elastic spring back cavity has only liquid oils 11, there is not other power source, such as nitrogen or the like, so we are provided with Returnning spring 9, and described Returnning spring 9 is connected and fixed by the groove on starting bar 8 top caps and piston rod 7 tops.
Claims (4)
1. lockable pulling force air spring, comprise cylinder body, pilot seal cover, stifled, the piston rod in back, the front end of described cylinder body is fixed with the pilot seal cover, it is stifled that end is fixed with the back, it is characterized in that: described cylinder body internal fixation has fixing every plug, described fixing every plug front and back side is respectively equipped with piston and valve body piston, and described piston is connected by piston rod with the valve body piston.
