An animal fence structure.The system includes: a door column.The tie has a crossbar；Two column,It is located below both sides of the cross bar；And two pivot setting rods,All of them are in the shape of "I".In front of the column,A sliding space is defined in each pivot bar；A sliding device,At the rear end of the door post,And in each sliding space of the two pivoted rods, the upper,Lower active displacement state；And two transmission mechanisms,At the rear end of the crossbar of the door post,And the sliding device is connected；When the transmission mechanism is in expansion action,And driving the sliding device up,Lower active displacement state,Allow the slide to be adjusted to the proper height,In order to control the advance and retreat of cattle；In this way,The sliding device is used to automatically control the lifting by the transmission mechanism.Therefore, the position of cattle before milking is to return cattle after milking.The fence structure can control animal movement quickly and has the effect of fast cleaning.一種動物柵欄結構，係包含：一門柱體，係具有一橫桿；二立柱，係位於該橫桿其兩側下方；以及二樞設桿，其各整體呈ㄈ型態，而各分別位於該立柱前方，各該樞設桿內則界定出一滑動空間；一滑動裝置，係設於該門柱體其後端處，並於該二樞設桿之各滑動空間內呈現上、下活動位移狀態；及二傳動機構，係設於該門柱體之橫桿其後端處，並於該滑動裝置呈連結狀態；當該傳動機構在進行伸縮動作時，而帶動該滑動裝置呈上、下活動位移狀態，讓該滑動裝置得以調整至適當高度，藉以控制畜養牛進退行動；藉此，利用該滑動裝置係由該傳動機構以自動方式控制升降，故於擠乳前之畜養牛定位以擠乳後畜養牛之歸位，即可達到快速控管動物行動及兼具快速清洗效果之柵欄結構者。
