Abstract
The invention provides a cylinder mechanism with an adjustable stroke. The cylinder mechanism with the adjustable stroke comprises a cylinder body, a piston and a piston rod. The cylinder body is provided with a baffle plate. The piston rod penetrates through the baffle plate and is provided with a polyurethane buffering ring in a sleeved mode. The piston rod is provided with a fixing stud in a rotating mode. The fixing stud is provided with an adjusting buffing ring and a locknut in a rotating mode, wherein the locknut is locked with the adjusting buffing ring. By adjusting the position of the adjusting buffer ring on the fixing stud, the distance for which the other end of the piston rod of the cylinder is extended is controlled and stroke control of the cylinder is achieved. The cylinder mechanism with the adjustable stroke is convenient to adjust and accurate in the stroke control, capable of ensuring that a double-rod cylinder is converted into the cylinder mechanism with the adjustable stroke for use and being applied to a plurality of specific occasions.
Description
Technical field
The present invention relates to a kind of increased stroke-adjustable gas cylinder mechanism, belong to the cylinder group technical field.
Background technique
Existing, two bars, oval piston, rod end female type cylinder are comprised of cylinder body, piston, piston rod three parts, and the stroke of cylinder is uncontrollable, and its applicable situation limits to very much.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of increased stroke-adjustable gas cylinder mechanism is provided.
Purpose of the present invention is achieved through the following technical solutions:
Increased stroke-adjustable gas cylinder mechanism, comprise cylinder body, piston and piston rod, characteristics are: at cylinder body baffle plate is installed, piston rod passes baffle plate and is set with the polyurethane buffering ring, be connected with fixed bolt on the piston rod, be installed with on the fixed bolt and adjust baffle ring and locking nut, locking nut is locked mutually with the adjustment baffle ring.
Further, above-mentioned increased stroke-adjustable gas cylinder mechanism, wherein, described buffering ring is the polyurethane buffering ring.
The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in:
By adjusting the position of baffle ring on fixed bolt, the distance that the control cylinder piston rod the other end stretches out realizes the Stroke Control of cylinder.Rational in infrastructure, easy to adjust, Stroke Control is accurate, two bar cylinders is changed into increased stroke-adjustable gas cylinder use, and can be applied in many specific occasions.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: structural representation of the present invention.
Embodiment
As shown in Figure 1, increased stroke-adjustable gas cylinder mechanism, comprise cylinder body 1, piston and piston rod, at cylinder body 1 baffle plate 2 is installed, piston rod passes baffle plate 2 and is set with polyurethane buffering ring 3, and buffering ring 3 is the polyurethane buffering ring, be connected with fixed bolt 6 on the piston rod, an end that is fixed bolt 6 short threads is screwed into piston rod box thread place and locking, is installed with on the fixed bolt 6 and adjusts baffle ring 4 and locking nut 5, and locking nut 5 is locked mutually with adjustment baffle ring 4.Easy to adjust, Stroke Control is accurate, two bar cylinders can be changed into increased stroke-adjustable gas cylinder and use, and can be applied in many specific occasions.
During concrete the application, unclamp locking nut 5 by open-end wrench, then adjust the position of baffle ring 4 on fixed bolt 6, the distance that the control cylinder piston rod the other end stretches out realizes the Stroke Control of cylinder.Two bar double-acting cylinders can be used as the single pole increased stroke-adjustable gas cylinder.
In sum, the present invention is rational in infrastructure, and is easy to adjust, and Stroke Control is accurate, two bar cylinders changed into increased stroke-adjustable gas cylinder use, and can be applied in many specific occasions.
What need to understand is: the above only is preferred implementation of the present invention; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
