The invention discloses a safety cylinder capable of automatically cutting off a rope. The cylinder comprises a cylinder body, a control mechanism, a cutting-off mechanism and a clamping mechanism, cover plates are arranged at the two ends of the cylinder body respectively, first through holes are formed in the middles of the cover plates, and a storage battery is arranged in the cylinder body; the control mechanism is arranged at one end of the cylinder body and comprises first springs connected with the outer ends of the cover plates at the corresponding ends of the cylinder body, two electrodes of which one ends are connected with the cover plates and which are arranged in the first springs at intervals, and conducting strips which are in contact with the other ends of the electrodes after the first springs compressed; and second through holes corresponding to the first through holes are formed in the middles of the conducting strips. The safety cylinder sleeves a pet rope, when thefirst spring at the left end or the right end of the cylinder body is extruded by an elevator door, the corresponding conducting strip makes contact with the corresponding electrode, the cutting mechanism cuts off the pet rope, a pet cannot be pulled by the pet rope to be tightly attached to the elevator door, the pet can be separated from the elevator door, and therefore the pet cannot be hung by the pet rope or pulled downwards, and the pet is prevented from being hurt or died due to tying.
本发明公开了一种可以自动切断绳索的安全筒,包括筒体、控制机构、切断机构和夹紧机构,筒体两端分别设有盖板,盖板中部设有第一通孔,筒体内设有蓄电池;筒体一端设置一个控制机构,控制机构包括有与筒体相应端盖板外端连接的第一弹簧,一端与盖板连接的、间隔设在第一弹簧内的两个电极,以及当第一弹簧压缩后与电极另一端接触的导电片;导电片中部设有与第一通孔对应的第二通孔。本发明套在宠物绳上,当筒体左端或右端的第一弹簧被电梯门挤压后,相应导电片和电极接触,切割机构就会切断宠物绳,本发明和宠物就不会被宠物绳拉着紧贴电梯门,宠物脱离电梯门,这样宠物就不会被宠物绳吊着或向下拉着,使得宠物不会被勒伤或者勒死。
