Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-3, a foldable minimally invasive valve measuring device includes a telescopic assembly 1, the telescopic assembly 1 includes a fixing rod 11; the top of the fixed rod 11 is sleeved with a fixed sleeve 12, and the outer side wall of the fixed sleeve 12 is hinged with a support frame 13; the bottom of the fixed rod 11 is rotatably connected with a screw rod 14 through a bearing, the outer side wall of the screw rod 14 is in threaded connection with a nut 15, and the support frame 13 is hinged with the nut 15; a fixed seat 16 is arranged at the bottom of the screw rod 14, and the fixed seat 16 is rotationally connected with the screw rod 14; the upper surface of the fixed seat 16 is provided with two guide rails 17, and the two guide rails 17 are symmetrically distributed along the screw rod 14; each guide rail 17 penetrates through the nut 15 and is fixedly connected with the fixing rod 11.
In the embodiment, the fixing rod 11 is arranged to support the screw rod 14, wherein the outer side wall of the bearing is fixedly connected with the fixing rod 11, the inner side wall of the bearing is fixedly connected with the screw rod 14, the screw rod 14 can be supported to rotate through the bearing, and friction generated by rotation of the screw rod 14 can be reduced; the support frame 13 is connected with the fixed rod 11 through the fixed sleeve 12 by arranging the fixed sleeve 12; through setting up lead screw 14, screw 15 and guide rail 17, because lead screw 14 drives screw 15 and rotates, screw 15 has two degrees of freedom of rotation and removal, and the degree of freedom of restriction rotation through guide rail 17 this moment can realize that screw 15 carries out the ascending slip of vertical direction on guide rail 16. When the screw 15 contacts the fixing rod 11, the support frame 13 can be expanded, so that the expanded support frame 13 can compare and measure the valve.
Further, a sub-frame 18 is arranged on the outer side wall of the screw nut 15; one end of the sub-frame 18 is hinged with the screw nut 15, and the other end of the sub-frame 18 is hinged with the supporting frame 13.
In the present embodiment, the sub-frame 18 is provided, and the support frame 13 is hinged to the screw 15 via the sub-frame 18, so that the support frame 13 can be easily retracted or extended via the sub-frame 18.
Further, a support member 111 is installed on an outer side wall of the fixing rod 11, and the guide rail 17 is fixedly connected with the fixing rod 11 through the support member 111.
In the present embodiment, the support 111 is provided so that the support 111 supports one end of the guide rail 17 and the fixing base 16 supports the other end of the guide rail 17, thereby improving the stability of the guide rail 17 in the present apparatus.
Further, a non-woven fabric 19 is mounted on an outer side wall of the support member 13.
