Abstract
The utility model relates to the technical field of cylinders, in particular to a guide rod cylinder. The guide rod cylinder comprises a pedestal and a cylinder, wherein the cylinder is vertically positioned on the pedestal, the cylinder consists of a cylinder body and a piston rod extending out of the cylinder body, the outer end of the piston rod is fixed on the pedestal, a guide holder is fixed on the cylinder body, the guide holder is provided with a pilot hole, a guide rod is arranged inside the pilot hole in a penetrating mode, and the lower end of the guide rod is fixedly disposed on the pedestal. Due to the fact that the guide rod cylinder can not rotate during usage, shortcomings and defects in the existing art can be effectively overcome. The guide rod cylinder is simple in structure and low in manufacturing cost.
Description
Technical field
The utility model relates to cylinder guidance device technique field, particularly a kind of guide rod cylinder.
Background technique
Cylinder is as the conventional machinery component unit, and common by people, it is widely used in the every field such as medical apparatus, furniture and auto parts machinery, in the cylinder generally with clean compressed air as transmission medium.Existing cylinder generally is not provided with guiding device, and in movement process, occurrence positions rotates easily, makes troubles to operation, is unfavorable for the use under some special occasions.So existing cylinder is carried out the structure innovation to be necessary in fact.
The model utility content
The purpose of this utility model is for the defective of prior art and deficiency, provides a kind of simple in structure, the guide rod cylinder that fabricating cost is low.
For achieving the above object, the utility model is by the following technical solutions:
A kind of guide rod cylinder described in the utility model, comprise base and vertically be located at cylinder on the base, described cylinder is comprised of the cylinder body piston rod outer with stretching out cylinder body, described piston rod outer end is fixed on the base, be fixed with guide holder on the described cylinder body, described guide holder is provided with pilot hole, is equipped with guide rod in the described pilot hole, and the guide rod lower end is fixed on the base.
Further, described pilot hole has two, is symmetrically set in the cylinder body both sides.
Further, described pilot hole inwall is provided with oil-impregnated bearing, and described guide rod passes oil-impregnated bearing.
After adopting said structure, the utility model beneficial effect is: be fixed with guide holder on the cylinder body described in the utility model, described guide holder is provided with pilot hole, is equipped with guide rod in the described pilot hole, and the guide rod lower end is fixed on the base.The utility model cylinder does not rotate in using process, has effectively overcome deficiency and defective that prior art exists, and it is simple in structure, and fabricating cost is fallen.
Description of drawings
Fig. 1 is overall structure schematic representation of the present utility model.
Among the figure:
1, guide rod; 2, piston rod; 3, base; 4, oil-impregnated bearing;
5, guide holder; 6, cylinder body; 7, pilot hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of guide rod cylinder described in the utility model comprises base 3 and vertically is located at cylinder on the base 3, and described cylinder is by cylinder body 6 and stretch out cylinder body 6 outer piston rods 2 and form.
Described piston rod 2 outer ends are fixed on the base 3, are fixed with guide holder 5 on the described cylinder body 6, and described guide holder 5 is provided with pilot hole 7, are equipped with guide rod 1 in the described pilot hole 7, and guide rod 1 lower end is fixed on the base 3.The preferred described pilot hole 7 of the utility model has two, is symmetrically set in cylinder body 6 both sides, and in other words, the preferred described guide rod 1 of the utility model has two, is symmetrically set in respectively cylinder body 6 both sides, arranges like this, can play better leading role.
Described pilot hole 7 inwalls are provided with oil-impregnated bearing 4, and described guide rod 1 passes oil-impregnated bearing 4, so arrange, and mainly play good lubrication, and guide rod 1 sliding effect is better.
When inflating in the cylinder, the partial-length that piston rod 2 stretches out cylinder body 6 increases, and cylinder body 6 and the guide holder 5 that is fixed on the cylinder body 6 move up, and because of the effect of guide rod 1, cylinder body 6 and guide holder 5 positions all can not rotate.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
