This utility model discloses an examination bed with an automatically changeable sheet, including a bed body connected to a liftable bed frame. The bed frame can adjust the vertical position of the bed body, and both ends of the bed frame are equipped with rotating rollers. A sheet is laid on the bed body, with one end of the sheet wound around one of the rotating rollers and the other end wound around the other rotating roller. One of the two rotating rollers is used to reel in an unused sheet, and the other is used to reel in a used sheet. An anti-detachment mechanism includes a first limiting part on the bed frame and a second limiting part on the rotating roller. The rotating roller can drive the second limiting part to connect with the first limiting part. When the second limiting part is connected with the first limiting part, the rotating roller can rotate relative to the second limiting part, and the second limiting part and the first limiting part can prevent the rotating roller from displacing in the longitudinal direction.

The utility model relates to the technical field of composite self-heat-preservation building block production equipment, and discloses a forming device for composite self-heat-preservation building block production, which comprises a forming platform, and a first forming die and a second forming die are uniformly placed on the surface of the top of the forming platform. Scraping assemblies are arranged in the first forming mold and the second forming mold correspondingly, each scraping assembly comprises a fixing block, guide holes are formed in the surfaces of the fixing blocks correspondingly, guide rods are arranged in the fixing blocks correspondingly, and limiting blocks are fixedly connected to the surfaces of the tops of the guide rods correspondingly; the surfaces of the bottoms of the four guide rods are jointly and fixedly connected with a concentric-square-shaped mounting plate, and the surfaces of the outer side walls of the concentric-square-shaped mounting plate are fixedly connected with concentric-square-shaped scrapers. According to the utility model, through the arrangement of the scraping component, residual redundant materials on the inner walls of the first forming mold and the second forming mold can be quickly cleaned after demolding, so that the cleaning time is greatly shortened, and the production efficiency is improved.

The application relates to the field of electromagnetic valve detection, and discloses a port size detection device for electromagnetic valve production, which comprises a workbench, a motor, a rotating block, two groups of connecting rods, a support and an adaptive roller. When the device is in abutment with the electromagnetic valve body, the telescopic column, the connecting rod one and the connecting rod two are driven to move outward. The pressure reading generated by the pressure sensor under the compression of the telescopic column is K2. The maximum value of all K2 and the difference value of K1 are taken to determine whether the electromagnetic valve body port roundness is within the roundness tolerance range, so that the function of rapidly detecting the electromagnetic valve body port roundness is realized, and the detection efficiency of the device is significantly improved.

The cushion block comprises a lower main body and an upper main body, a plurality of blind holes are formed in the lower main body, a plurality of through holes are formed in the upper main body, the through holes correspond to the blind holes, the lower main body and the upper main body are fixedly connected through first bolts, and the first bolts are in threaded connection with the through holes and the blind holes respectively. The lower end of the lower main body is provided with first anti-skid grains, and the upper end of the upper main body is provided with second anti-skid grains. Limiting grooves are formed in the outer side of the lower body, a threaded hole is formed in each limiting groove, the limiting grooves are used for installing limiting pieces, and the limiting pieces are fixedly connected with the lower body through second bolts. Adjusting pieces are arranged between the lower body and the upper body and can be increased or decreased according to requirements. The floor thickness can be controlled, the construction stability is improved, and the construction requirements of different floors are met.

The utility model provides a sliding rail closer of a side-hung sliding door, which comprises a movable part and a fixed part which are matched for use, pulley mounting cavities which can be communicated when the movable part and the fixed part are matched are arranged in the movable part and the fixed part, and pulley rails are arranged at the bottoms of the pulley mounting cavities; a first extension part is arranged at the end part of the pulley track on the moving part; a second extension part is arranged at the end part of the pulley track on the fixed part; the first extension part and the second extension part are matched to form a splicing track, and the splicing track is communicated with the pulley track. Compared with the prior art, the continuous splicing track is formed by arranging the first extending part and the second extending part, the matching gap between the fixed part and the movable part is completely filled, and when the pulley of the sliding door leaf passes through the closer, the splicing track and the pulley track form a non-breakpoint continuous guide surface; longitudinal displacement and transverse shaking generated when the pulley passes through the gap are effectively avoided, and the stability and smoothness of the door leaf in the push-pull process are remarkably improved.
