The utility model relates to the technical field of movable hog houses, and discloses a movable hog house convenient for pigs to eat fresh rotten vegetable leaves, the top of a bottom frame is fixedly provided with a transverse frame, and the top of the transverse frame is fixedly provided with a hog house frame. The movable pig house and the cargo carrying truck are combined to achieve the advantage of being capable of moving at any time, waste vegetables nearby can be consumed in different places and areas, and the waste vegetables are not limited to one place; by adopting the pig house, the pig house can be dragged to the required area according to the rotten vegetable condition of each area and the local planting condition, the rotten vegetable of each area can be consumed, and the purpose of fully utilizing resources is achieved.

The application discloses an electric switch key testing device, belonging to the electric switch testing field, comprising a base, a cylinder assembly fixed in the base, a lifting assembly movably inserted in the base and connected with the telescopic end of the cylinder assembly, a plurality of pressing parts connected with the lifting assembly, an XY double-shaft platform connected with the upper end of the base, a workpiece positioning seat fixedly connected with the upper end of the XY double-shaft platform, and an oil stain applying part connected with the upper end of the base; the oil stain applying part can spray oil stains to the membrane switch fixed on the workpiece positioning seat, more truly reproducing the scene of 'polluting while operating' in actual use; under the stress of mechanical pressing, the oil stains are more easily extruded into the membrane interlayer, the conductive path or the air permeable hole, thereby accelerating the exposure of potential sealing defects, material compatibility problems or circuit design weaknesses, and the dynamic failure mode of the membrane switch in the oil stain environment can be exposed earlier and more effectively.

The application relates to the technical field of shoes, and provides a leisure shoe with a hardening-resistant vamp, which comprises a vamp, the vamp comprises a surface layer, an elastic layer and an inner layer which are sequentially arranged from outside to inside, the elastic layer comprises an elastic framework and elastic pieces, the elastic framework is provided with a plurality of reset grooves, the elastic pieces are provided in groups, and all the elastic pieces are respectively arranged in the reset grooves. The leisure shoe with the hardening-resistant vamp can delay the hardening effect of the vamp.

The application provides a regenerated cellulose fiber fabric processing device and relates to the technical field of cellulose fabric processing.The device comprises a workbench, the front part of the workbench is provided with an inclined outlet, the two sides of the workbench in the width direction are both fixed with side baffles, the upper sides of the two side baffles are both slidably connected with a sliding frame, the sliding frame is provided with an upper cover and a connecting frame which are distributed in front and back and are slidably connected with the sliding frame, and the upper cover and the connecting frame both contain horizontal side walls in the width direction and are both fixedly connected with the sliding frame through first springs at the horizontal side walls. The combined water of the wrinkled part of the regenerated cellulose fiber fabric is greatly reduced through the action of the vacuumizing and dry ice gas after the wrinkled part of the regenerated cellulose fiber fabric is ironed through the ironing device, and the degree of the hardness of the wrinkled part of the regenerated cellulose fiber fabric is reduced, so that the clothes are more comfortable to wear.

The present application discloses a converter slag blocking device, in which a raised platform and a butt joint platform are arranged in the brick arrangement, and the bowl brick is cancelled, the service life of the brick arrangement and the taphole is improved, the original brick arrangement and the easy brick arrangement are arranged, the precision of the brick arrangement installation is improved, the brick arrangement pressing plate is a flat plate type and is provided with a stepped lifting hole and a lifting hook in the lifting hole, the bending deformation of the brick arrangement pressing plate is reduced, the quick lifting problem of the brick arrangement pressing plate is solved, the precision of the brick arrangement installation is further improved, the brick arrangement overhang of the buffer base, the pressing plate relaxation chamber and the bolt stretching pool are arranged, the flexible fire clay contact between the buffer base and the brick arrangement is ensured at all times, the problems of the bending deformation of the inner slide plate cavity plate, the plate surface crack fracture of the inner slide plate, the slide plate clamping steel and the like caused by the over-high installation of the brick arrangement and the brick arrangement pressing plate are solved, and the stability of the mechanism surface pressure is obviously improved, the converter slag blocking device is safe and long in service life, stable in operation, low in comprehensive cost and simple in operation and maintenance.

The application discloses an early-strength heat-insulation type light plastering gypsum mortar and a preparation method thereof. The early-strength heat-insulation type light plastering gypsum mortar comprises the following raw materials in parts by weight: 550-800 parts of gypsum powder, 100-300 parts of heavy calcium, 100-300 parts of light aggregate, 50-100 parts of inorganic retarder, 1-5 parts of early-strength water reducing agent, 1-5 parts of reinforcing agent, 1-4 parts of cellulose ether, 5-15 parts of redispersible latex powder and 400-450 parts of water. The early-strength water reducing agent is prepared by reacting high-purity gypsum and polycarboxylic acid water reducing agent solution, and high-activity functional groups in the polycarboxylic acid water reducing agent are inlaid on the surface of fibrous calcium sulfate whiskers. The light aggregate is prepared from autoclaved aerated concrete. The inorganic expanding agent is used to adjust the setting time, the early-strength water reducing agent and the reinforcing agent are used to improve the compressive strength and bonding strength of the gypsum mortar, and the autoclaved aerated concrete is used to replace traditional light aggregates such as vitrified small balls and expanded vermiculite, so that the heat preservation performance of the gypsum mortar is improved.
