The invention relates to a quickly locked opening shrinking patterned sleeve of a porous special-shaped mold core. The patterned sleeve is a structure which is used for sleeving and locking a porous special-shaped mold core positioning column (1). An inlet end (4) where the positioning column (1) stretches is left in the patterned sleeve. At least two openings (2) are formed in the inlet end (4) where the positioning column (1) stretches, so that a holding claw (3) which shrinks inward and holds the porous special-shaped mold core positioning column (1) during use is formed on the side wall, corresponding to the inlet end (4), of the patterned sleeve. The difference is that positioning and locking of all freedom degrees are finished by hammering at one time. An expansion bolt overturns externally while the quickly locked opening shrinking patterned sleeve overturns internally.

The invention discloses a hoisting mechanism of a gantry crane. The hoisting mechanism comprises a left hoisting assembly (1) and a right hoisting assembly (2) which are symmetrically arranged on a trolley rack (3), wherein the left hoisting assembly (1) and the right hoisting assembly (2) are in movable connection with the trolley rack (3), so that the left and right hoisting assemblies move leftward and rightward relatively to the trolley rack; and the contact hoisting points between the left hoisting assembly (1) and a hoisting tool (4) as well as between the right hoisting assembly (2) and the hoisting tool (4) are located just above the hoisting point of the locking and hoisting object of the hoisting tool (4). By adopting the hoisting mechanism, the stresses of the hoisting tool and the trolley rack are improved, thus the weights of the hoisting tool and the trolley rack are alleviated, the hoisting load is alleviated and the energy is saved. In addition, the invention also discloses the gantry crane comprising the hoisting mechanism.

A lamp buckle structure is used for detachably connecting a first component and a second component of a lamp, and the second component is provided with a buckle. The lamp buckle structure comprises a base, a lever, a rotating shaft and a telescopic rod. The base comprises a fixed bottom plate and two clamping arms. The lever comprises a handle portion and two connecting arms arranged at one end of the handle portion. Supporting arms are rotatably connected with the connecting arms. The rotating shaft is rotatably connected with the connecting arms, a cylindrical hole is formed in the rotating shaft, the axial direction of the cylindrical hole is perpendicular to the axial direction of the rotating shaft, the telescopic rod is in threaded connection with the rotating shaft, and the telescopic rod rotates relative to the rotating shaft and can move along the cylindrical hole. A retaining ring is rotatably connected with the end, away from the rotating shaft, of the telescopic rod, and the retaining ring can be hung on the buckle. When the handle portion is turned over, the lever rotates relative to the base, the telescopic rod moves relative to the rotating shaft, and the distance between the retaining ring and the rotating shaft is adjusted until the retaining ring is clamped to the buckle. After the lamp buckle structure is assembled, the magnitude of locking force can be adjusted according to needs. The invention further provides the lamp.

The invention discloses a prestressed anchor for highway bridge construction. and a second sleeve, the right side of the first sleeve is provided with a corrugated pipe, the right end of the first sleeve is fixedly connected with the left end of the corrugated pipe, and the left side of the first sleeve is provided with a baffle , the left end of the first sleeve is fixedly connected with the right side of the baffle, the left side of the baffle is provided with a plug block, the left side of the baffle is fixed with the right end of the plug block, the plug The left side of the block is provided with a second sleeve, and the left end of the plug block is fixedly connected with the right end of the second sleeve. The prestressed anchorage for highway bridge construction can effectively ensure the locking force through multi-stage locking, so as to reduce the failure rate, thereby effectively prolonging the service life of the whole mechanism, significantly improving the practicability, and the use method is simple. Easy to promote.
