The utility model discloses an assembly type high-strength prestress broken line type roof truss U-shaped hoisting accessory which comprises a hoisting main body, the top of the hoisting main body is fixedly connected with a connecting piece, two through holes are formed in the hoisting main body, and two lock bolts are jointly arranged in the two through holes in a clamped mode. According to the utility model, firstly, the roof truss is punched, after punching, the bidirectional threaded rod is rotated, so that the two threaded sleeves move towards each other or away from each other outside the bidirectional threaded rod, the two limiting sleeves can coincide with the two round holes outside the roof truss through the linkage of the two sliding rods, and then the lock bolt penetrates through the two limiting sleeves, so that the connection operation of hoisting is realized; the drilling distance outside the roof truss does not need to be accurately measured in the process, so that the hoisting and assembling process is more efficient and faster, through the embedded tungsten steel alloy frame, the hardness of the whole device can be improved, the pulling resistance and the hoisting capacity of the whole device in the hoisting operation process can be improved, and meanwhile the durability and the stability in the hoisting process are improved.

This utility model relates to the field of throttling device technology, specifically a throttling device for a water purifier, including a throttling pipe. The inlet and outlet ends of the throttling pipe are respectively fixedly connected to an inlet pipe and a subsequent pipe via a first semi-circular sleeve and a second semi-circular sleeve, respectively, in cooperation with two sets of fixing components. An installation plate is fixedly connected to both ends of the throttling pipe. This utility model, through the combination of the first and second semi-circular sleeves and the fixing components, achieves rapid installation of the throttling pipe. Compared to the traditional method of connecting via multiple bolts and flanges, this connection structure requires no excessive tools and eliminates the need for repetitive and tedious bolt tightening operations, greatly simplifying the installation process, effectively saving installation time and labor costs, and significantly improving the convenience and efficiency of throttling pipe installation, making the entire water purifier assembly process faster and more efficient.
