Description

A kind of fender pile structure improvement
Technical field
The present invention establishes and a kind of fender pile structure improvement, and finger can whole process provide effective pressure relief mechanism especially, in order to do the disappearance that can avoid the push rod action to have some setbacks, and then can reach the effect that promotes production reliability and promote convenience of use.
Background technique
At present; Fender pile is between a kind of object of being located at two relative movement, is used to cushion the device of its speed of related movement, to reach collision power that reduces between the object or the effect that reduces noise; On the door body or drawer sliding rail that for example is applied to return automatically; Seeing also shown in Figure 1 is the partial enlarged drawing of a traditional fender pile, and it mainly lies in and axially is equipped with an axostylus axostyle 12 in the outer tube 3, and the link 13 that is connected in these axostylus axostyle 12 1 ends is provided with a piston ring 14; This piston ring 14 is provided with a loop portions 141 and a skirt section 142; By this, in order to do when these axostylus axostyle 12 courts are shifted near these piston ring 14 directions, the loop portions 141 and the skirt section 142 of this piston ring 14 can be strutted by the ejection of this link 13 equably; And make this loop portions 141 and the inwall of skirt section 142 and outer tube 3 form good airtight conditions and friction, and then make the purpose that this fender pile can reach provides cushioning effect.
The fender pile that this is commonly used; Though it can reach the purpose that cushioning effect is provided; But when these axostylus axostyle 12 courts are shifted near these piston ring 14 directions, these outer tube 3 inner air are compressed, thereby when this axostylus axostyle 12 promotes piston rings 14 near outer tube 3 bottoms; The situation of the thrust of axostylus axostyle 12 less than outer tube 3 internal air pressures often takes place; Cause axostylus axostyle 12 successfully to advance, the loop portions 141 that must wait until this piston ring 14 restores to the original state with skirt section 142 and just can continue to advance when making air pressure in the outer tube 3 less than the thrust of axostylus axostyle 12, causes this to commonly use its axostylus axostyle 12 actions of fender pile and has some setbacks; And then causing production reliability reduction and user's puzzlement, historical facts or anecdotes has necessity of improvement.
Therefore, how disappearance such as above-mentioned is forgone, be the place of the technical difficulties of this case creator institute desire solution.
Summary of the invention
Because existing fender pile; Because of the air pressure in the cushion stroke middle external tube is difficult for discharging, cause the axostylus axostyle action to have some setbacks, so the purpose of this creation is to provide a kind of fender pile structure improvement; Be respectively equipped with pod apertures and open-work by this push rod and piston piece; And this open-work perforation that is connected with pod apertures, and can effective pressure relief mechanism be provided whole process, in order to do can avoid the cushion stroke latter end be prone to because of air pressure greater than push rod thrust; The disappearance that causes the push rod action to have some setbacks, and then make this creation can reach lifting production reliability and the effect of promoting convenience of use.
For reaching above purpose, this creation system provides a kind of fender pile structure improvement, and it comprises:
One outer tube is provided with a hollow portion in this outer tube, these outer tube two ends are respectively equipped with the bottom of a closed shape and the top of an open shape;
One push rod, this push rod system is arranged in the hollow portion of this outer tube slippingly, and these push rod two ends are respectively equipped with a connecting part and by drive portion, further are provided with one in this push rod and run through this connecting part and by the pod apertures of drive portion;
One piston piece, these piston piece two ends have an afterbody and a contacting part respectively, be provided with in its afterbody of this piston piece one with its connecting part of this push rod corresponding by the connecting part; It can be nested with its connecting part of this push rod by the connecting part and engage admittedly in order to do making this piston piece, and the external diameter of this contacting part is slightly larger than the internal diameter of this its hollow portion of outer tube again, by this; Connect in order to do making its contacting part of this piston piece offset to contact with its hollow portion inwall of outer tube; Further be provided with an open-work in this piston piece in addition, this open-work and this are connected by the connecting part, and this open-work runs through the afterbody and the contacting part of this piston piece; By this, in order to do making the perforation that can be connected with its pod apertures of push rod of its open-work of this piston piece.
Be respectively equipped with pod apertures and open-work by this push rod and piston piece; And this open-work perforation that is connected with pod apertures; And can effective pressure relief mechanism be provided whole process; In order to do can avoid the cushion stroke latter end be prone to because of air pressure greater than push rod thrust, the disappearance that causes the push rod action to have some setbacks, and then this creation can be reached promote production reliability and the effect of promoting convenience of use.
