Abstract
本发明公开一种千斤顶伸缩装置，包括固定底盘、脚板、支柱、外置弹簧、起重圆饼、内置弹簧、固定圆盘和螺丝钉；所述支柱位于固定底盘圆心位置，所述脚板位于固定底盘一侧，所述外置弹簧位于支柱下端，所述内置弹簧位于支柱上端，所述起重圆饼位于外置弹簧和内置弹簧之间，所述固定圆盘位于支柱上方，所述螺丝钉穿过固定圆盘位于固定圆盘上方。由于本千斤顶伸缩装置采用中间部位的起重圆饼进行顶起，这样将十分便于千斤顶的安放。在放下被顶起的重物时，由于外置弹簧会提供一定的缓冲力，这样就能避免千斤顶被砸坏的事故发生。
The invention discloses a jack telescopic device, which comprises a fixed chassis, a foot plate, a pillar, an external spring, a lifting round cake, an inner spring, a fixed disk and screws; the pillar is located at the center of the fixed chassis, and the foot plate is located at a side, the external spring is located at the lower end of the pillar, the internal spring is located at the upper end of the pillar, the lifting disc is located between the external spring and the internal spring, the fixed disk is located above the pillar, and the screw passes through the fixed circle The disc is located above the fixed disc. Because the jack telescopic device adopts the lifting round cake at the middle part to jack up, it will be very convenient for the placement of the jack. When putting down the jacked-up heavy object, because the external spring will provide a certain buffer force, the accident of the jack being smashed can be avoided like this.
Description
技术领域 technical field
本发明涉及一种千斤顶伸缩装置。 The invention relates to a jack telescopic device.
背景技术 Background technique
千斤顶是一种用钢性顶举件作为工作装置，通过顶部托座或底部托爪在行程内顶升重物的轻小起重设备。因其结构简单，小巧灵活，便于携带，实用性强而受到人们的青睐。现有的千斤顶多是通过伸缩装置上部直接把重物顶起来，在这个过程中千斤顶安放比较困难，且在放下被顶起的重物时由于重力加速度容易导致千斤顶被砸坏。 Jack is a kind of light and small lifting equipment that uses a rigid top lifting part as a working device, and lifts a weight in a stroke by a top bracket or a bottom claw. Because of its simple structure, compactness, flexibility, portability and strong practicability, it is favored by people. Most of the existing jacks directly lift up the weight through the upper part of the telescopic device. During this process, it is difficult to place the jack, and the jack is easily broken due to the acceleration of gravity when the lifted weight is put down.
发明内容 Contents of the invention
本发明要解决的技术问题是在于实现一种千斤顶伸缩装置，此装置在顶起重物时便于安放，且在放下被顶起的重物时不会因为受力不均匀而导致千斤顶被砸坏的事故发生。 The technical problem to be solved by the present invention is to realize a jack telescopic device, which is easy to place when lifting heavy objects, and will not cause the jack to be smashed due to uneven force when putting down the lifted heavy objects accident happened.
为解决上述问题，本发明采用如下技术方案：一种千斤顶伸缩装置，包括固定底盘、脚板、支柱、外置弹簧、起重圆饼、内置弹簧、固定圆盘和螺丝钉；所述支柱位于固定底盘圆心位置，所述脚板位于固定底盘一侧，所述外置弹簧位于支柱下端，所述内置弹簧位于支柱上端，所述起重圆饼位于外置弹簧和内置弹簧之间，所述固定圆盘位于支柱上方，所述螺丝钉穿过固定圆盘位于固定圆盘上方。 In order to solve the above problems, the present invention adopts the following technical solutions: a jack telescopic device, including a fixed chassis, a foot plate, a pillar, an external spring, a lifting round cake, an internal spring, a fixed disc and a screw; the pillar is located at the center of the fixed chassis position, the foot plate is located on one side of the fixed chassis, the outer spring is located at the lower end of the pillar, the inner spring is located at the upper end of the pillar, the lifting disc is located between the outer spring and the inner spring, and the fixed disc is located at the pillar Above, the screw passes through the fixed disc and is located above the fixed disc.
作为优选，所述起重圆饼下方设置一凸起圆环。 Preferably, a protruding ring is arranged under the lifting disc.
作为优选，所述外置弹簧设置在凸起圆环外侧。 Preferably, the external spring is arranged outside the raised ring.
作为优选，所述内置弹簧直径小于起重圆饼内径。 Preferably, the diameter of the inner spring is smaller than the inner diameter of the lifting disc.
本发明的有益效果是：由于本千斤顶伸缩装置采用中间部位的起重圆饼进行顶起，这样将十分便于千斤顶的安放。另，在放下被顶起的重物时，由于外置弹簧会提供一定的缓冲力，这样就能避免千斤顶被砸坏的事故发生。 The beneficial effects of the present invention are: since the jack telescopic device adopts the lifting round cake at the middle part for jacking up, it will be very convenient for the placement of the jack. In addition, when the jacked-up heavy object is put down, the external spring will provide a certain buffer force, so that the accident of the jack being smashed can be avoided.
