Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the present invention includes a first piston chamber 1 and a second piston chamber 3, wherein the middle portion of the right side of the first piston chamber 1 is communicated with the left end of the second piston chamber 3; a first piston and a first piston rod 2 are arranged in the first piston cavity 1, the first piston rod 2 can rotate along the first piston, and the first piston rod 2 penetrates through the left side wall of the first piston cavity 1 in a threaded mode; a second piston and a second piston rod 4 are arranged in the second piston cavity 3, a sleeve 5 capable of moving left and right is sleeved at the right end of the second piston rod 4, an upper right supporting rod 6 and a lower right supporting rod 6 are hinged on the sleeve 5, an upper left supporting rod 7 and a lower left supporting rod 7 are hinged on the second piston rod 4, and the free ends of the left supporting rod 7 and the right supporting rod 6 which are positioned on the same side are hinged together;
In order to rotate the first piston rod 2 conveniently, a handle is installed at the left end of the first piston rod 2.
In order to prevent slipping, a cushion block 11 is connected at the hinged point of the left support rod 7 and the right support rod 6 in an intersecting manner, and a groove is formed in the cushion block 11.
For saving labor, the cross section of the second piston is smaller than that of the first piston.
In order to realize that the first piston rod 2 can rotate along the first piston, the end surface of the first piston is provided with an installation block, the end part of the first piston rod 2 is arranged in the installation block, and a bearing is arranged between the first piston rod 2 and the installation block.
In order to realize extrusion and lubrication, the first piston cavity 1 and the second piston cavity 3 are filled with hydraulic oil.
The utility model discloses during the use, at first because sleeve 5 and second piston rod 4 can relative slip, and sleeve 5 passes through connecting plate 8 to be fixed on the lateral wall in second piston chamber 3, consequently after extracting bolt 10, sleeve 5 alright in order to freely slide this moment.
In addition, due to the hinged relationship of the left strut 7 and the right strut 6, the distance between the two cushion blocks 11 can be adjusted when the sleeve 5 is slid left and right.
Therefore, when the telescopic prop is used, the handle is firstly rotated to enable the first piston rod 2 to reset leftwards, then the sleeve 5 is slid, so that the distance between the left cushion block and the right cushion block 11 is adjusted, and the left cushion block and the right cushion block 11 can be quickly supported between a left reinforcing steel bar and a right reinforcing steel bar to be propped open or other objects; when the left cushion block and the right cushion block 11 cannot be manually expanded continuously, the bolt 10 penetrates through the positioning hole 9 in the connecting plate 8 and is screwed on the side wall of the second piston cavity 3, and the relative position of the sleeve 5 and the second piston cavity 3 is fixed.
Then, the first piston rod 2 can be rotated, and the area of the first piston is larger than that of the second piston, so that the right extrusion force of the second piston rod 4 can be amplified according to the principle that the pressure intensity and the area are in inverse proportion, and the aim of saving labor is fulfilled. Meanwhile, the purposes of saving labor and preventing backward movement can be further achieved through the threaded connection of the first piston rod 2.
Through rotating first piston rod 2, make first piston rod 2 remove rightwards, then second piston rod 4 also can remove rightwards, make the further increase of distance between two cushion 11 then alright play the purpose of supporting two adjacent reinforcing bars to enlarge the clearance, perhaps support the heavy object, realize the rescue purpose.
Because the cushion block 11 is adopted to support the object, the stability of the support can be ensured, and the deviation and the slippage are prevented.
After the rescue is finished, the bolt 10 is pulled out, so that the purpose of quick reset can be achieved, and meanwhile, the device is convenient, light and handy, can be held by hands, is wide in application range, can be used by multiple devices simultaneously, and improves the effect.
