Abstract
A spring type shock absorber comprises a liquid storage cylinder, a piston rod and a piston rod cover, wherein the piston rod is connected with the liquid storage cylinder, and the piston rod cover is installed on the piston rod in a sleeved mode and is covered on the liquid storage cylinder. A spring base is installed outside the liquid storage cylinder, a spring upper cover is installed outside the piston rod, a spring which is sleeved outside the piston rod and the liquid storage cylinder is installed between the spring upper cover and the spring base, the outside of the liquid storage cylinder is provided with an external thread, the inside of the spring base is provided with an internal thread, and the inner thread is matched with the external thread to enable the spring base to be installed outside the liquid storage cylinder. The spring type shock absorber has the advantages that the spring base is connected with the liquid storage cylinder through the threads, the rigidity of the spring can be adjusted through the position of the spring base, wherein the position of the spring base is located on the liquid storage cylinder, and therefore the spring type shock absorber can achieve good shock absorbing effect.
Description
Technical field
The utility model relates to a kind of spring type shock absorber.
Background technique
Existing spring type shock absorber, mainly comprise surge drum, the piston rod that links to each other with this surge drum and be sleeved on this piston rod and be placed on piston rod cover cap on the described surge drum, described surge drum is equipped with spring pedestal outward, described piston rod is equipped with the spring loam cake outward, is provided with between this spring loam cake and the described spring pedestal to be sleeved on described piston rod and the outer spring of surge drum.Because spring pedestal is to be welded on the surge drum, and the spring loam cake also is fixedly connected with piston rod, so that the distance between spring loam cake and the spring pedestal is fixed, thereby cause the rigidity of spring unadjustable, spring is long-term so uses rear its rigidity to diminish, thereby so that damping effect is not fine.
Summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides that a kind of stiffness coefficient simple in structure, spring is adjustable, the spring type shock absorber of good damping effect.
The technical scheme in the invention for solving the technical problem is: a kind of spring type shock absorber, comprise surge drum, the piston rod that links to each other with this surge drum, and be sleeved on this piston rod and be placed on piston rod cover cap on the described surge drum, described surge drum is equipped with spring pedestal outward, described piston rod is equipped with the spring loam cake outward, be provided with between this spring loam cake and the described spring pedestal and be sleeved on described piston rod and the outer spring of surge drum, described surge drum is provided with outside thread outward, be provided with internal thread in the described spring pedestal, thereby described spring pedestal matches with outside thread by described internal thread and is installed in outside the described surge drum.
Further, the outside that described surge drum is positioned at described spring pedestal outward also is provided with set screw nut, after spring pedestal is adjusted to suitable position, set screw nut is screwed to the outside of adjusting base again, can prevent that in use spring pedestal skids.
Further, described spring has two, and is separated by a setting sleeve between two springs, and described setting sleeve is sleeved on also can be along described surge drum slippage on the described surge drum, and the steel wire diameter of described two springs is different.In use, setting sleeve can be subjected to the load to-and-fro motion and thereupon motion with two springs, the setting of two springs, ratio of height to diameter is little, avoided being subjected to the spring bending after the load and produce mechanical friction with miscellaneous part and cause abnormal sound, two springs adopt the steel wire of different-diameter to make, and have reduced cost of production.
Further, being positioned on the outer part of described surge drum of described piston rod is set with the flexible dustproof cover that is connected with described surge drum, has dustproof effect.
The utility model is spun on set screw nut first on the outside thread of surge drum when assembling, spring pedestal is spun on the outside thread of surge drum again, then loads onto successively first spring, setting sleeve, second spring, at last fixing spring loam cake on piston rod.When needing Regulation spring rigidity, only need to turn the position of spring pedestal on surge drum can realize, adds strong fix by set screw nut after regulating.Working principle of the present utility model is identical with spring type shock absorber of the prior art, does not repeat them here.
The beneficial effects of the utility model are: owing to be threaded connection between spring pedestal and the surge drum, so that the rigidity of spring can regulate by the position of spring pedestal on surge drum, thereby so that the utility model can reach good damping effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of spring type shock absorber, comprise surge drum 1, the piston rod 2 that links to each other with this surge drum 1, and be sleeved on this piston rod 2 and be placed on piston rod cover cap 3 on the described surge drum 1, the described surge drum 1 outer spring pedestal 4 that is equipped with, the described piston rod 2 outer spring loam cakes 5 that are equipped with, be provided with the spring that is sleeved on outside described piston rod 2 and the surge drum 1 between this spring loam cake 5 and the described spring pedestal 4, the described surge drum 1 outer outside thread that is provided with, be provided with internal thread in the described spring pedestal 4, thereby described spring pedestal 4 matches with outside thread by described internal thread and is installed in outside the described surge drum 1, and the described surge drum 1 outer outside that is positioned at described spring pedestal 4 also is provided with set screw nut 6.
Described spring has two, and separated by a setting sleeve 7 between two springs, described setting sleeve 7 is sleeved on also can be along described surge drum 1 slippage on the described surge drum 1, the steel wire diameter of described two springs is different, in use, setting sleeve 7 can be subjected to the load to-and-fro motion and thereupon motion with two springs, the setting of two springs, ratio of height to diameter is little, avoided being subjected to the spring bending after the load and produce mechanical friction with miscellaneous part and cause abnormal sound, two springs adopt the steel wire of different-diameter to make, and have reduced cost of production.Being positioned on described surge drum 1 part outward of described piston rod 2 is set with the flexible dustproof cover 8 that is connected with described surge drum 1, has dustproof effect.
The utility model is when assembling, first set screw nut 6 is spun on the outside thread of surge drum 1, again spring pedestal 4 is spun on the outside thread of surge drum 1, then loads onto successively first spring 9, setting sleeve 7, second spring 10, at last fixing spring loam cake 5 on piston rod 2.When needing Regulation spring rigidity, only need to turn the position of spring pedestal 4 on surge drum 1 can realize, adds strong fix by set screw nut 6 after regulating, and can prevent that in use spring pedestal 4 skids.Working principle of the present utility model is identical with spring type shock absorber of the prior art, does not repeat them here.
