The application provides a textile rubber roller detection device, and belongs to the technical field of textile machinery, which is used to solve the technical problem that the existing detection equipment cannot continuously detect the surface roundness and flatness of the textile rubber roller and has low detection efficiency. The device comprises a rack and a support platform, the rack is provided with a driving roller which is rotatably arranged, two conveying belts are installed on the driving roller, a chain is arranged in the middle of the conveying belts, a base is slidably arranged on the conveying belts, a sprocket is rotatably arranged on the base, a clamping mechanism is arranged on the base, a transmission mechanism is arranged between the clamping mechanism and the sprocket, a detection mechanism is arranged on the support platform, and locking mechanisms are arranged on the two sides of the support platform. The textile rubber roller detection device can automatically detect the surface roundness and flatness and the roundness of the textile rubber roller during the movement of the textile rubber roller, can realize continuous detection, does not need to wait for the feeding and discharging time, improves the detection efficiency, can detect textile rubber rollers with different diameters, and has a wide range of use.

The utility model discloses a blocking piece for a pleat shoveling machine, and belongs to the technical field of pleat shoveling machines. The blocking piece for the pleat shoveling machine comprises a connecting mechanism, an adjusting mechanism and a gear dividing mechanism, the connecting mechanism comprises a transverse rod, and a connecting block is fixedly installed on the bottom side of the transverse rod; the adjusting mechanism comprises an adjusting rod, a plurality of pairs of mounting holes are formed in the upper end of the adjusting rod, first fixing bolts are movably inserted into one pair of mounting holes, one ends of the pair of first fixing bolts are in threaded connection with the outer side of one end of the cross rod, and an inserting hole is formed in the bottom end of the adjusting rod; the gear dividing mechanism comprises an inserting rod, the inserting rod is movably inserted into the inserting hole, a pressing plate is fixedly installed at one end of the inserting rod, an inclined plate is fixedly installed at one end of the pressing plate, and a partition plate is fixedly installed at the center of the bottom end of the inclined plate.

This utility model discloses a combined structure of sheet piles and I-beams, relating to the field of civil engineering technology. It includes an I-beam body, a sheet pile body, a fixing block, and a protective cover. A sliding rod is fixedly connected to the back of the protective cover, and a locking hole is provided in the middle of the protective cover. A positioning plate is fixedly connected to the middle of the cavity of the locking hole, and telescopic springs are fixedly connected to both sides of the positioning plate. This utility model, by setting up a protective cover, can effectively protect the connection between the I-beam body and the sheet pile body. The sliding rod on the back of the protective cover cooperates with the sliding groove, slider, and sliding rod on the inner side of the I-beam body, allowing for flexible adjustment of the protective cover's position to better adapt to different working scenarios and protection requirements. Simultaneously, the locking structure composed of the positioning plate, telescopic springs, movable plate, and locking plate within the locking hole ensures that the protective cover is stably fixed in the appropriate position, preventing it from sliding or falling off.

The utility model discloses an indoor advertising machine base device, and belongs to the field of advertising machines. The device comprises a base body, a sliding rod, a bottom plate, a limiting piece and an anti-skid piece. A mounting chamber is formed in the base body, and sliding grooves communicating with the mounting chamber are formed in the two sides of the base body correspondingly. The sliding rod is slidably connected into the sliding groove. The bottom plate is rotationally connected to the sliding rod. The limiting piece is arranged on the base body and is used for limiting the sliding rod; the limiting piece comprises a fixing ring fixedly arranged on the side wall of the base body. A second through groove is formed in one side of the fixing ring, and a limiting pad is slidably connected to the second through groove. When the advertising machine is not used, the bottom plate is retracted into the mounting chamber. According to the display device, the occupied space can be greatly reduced, on one hand, the multiple base bodies can be tightly arranged, the storage and transportation cost is effectively reduced, on the other hand, the device is easier to carry, the flexibility of the device can be improved, and the display position can be rapidly adjusted according to different marketing requirements and site changes.
