The invention relates to a split type sleeve steel bar connecting structure which comprises two steel bars to be connected and a split type sleeve. Expanded heads are arranged at the ends of the steel bars; the split type sleeve comprises more than two sections of sleeve body units which are divided along the axial direction of the sleeve and a tightening sleeve which hoops the sleeve body units together; the cylinder body units are mutually spliced to form a complete cylinder body, the expansion head is buckled in the cylinder body, and the size of the port of the buckled sleeve is smaller than that of the expansion head; and the tightening sleeve is rotationally clamped on the peripheral surface of the cylinder body, so that the expanding head is clamped in the sleeve, and the connection of the two reinforcing steel bars is realized. The connecting structure adopts mechanical connection which is more reliable than grouting connection, quality inspection can be carried out, and the connection is proved to be effective as long as the tightening sleeve is tightened. The structure is simple to operate, does not need special process or equipment, only needs manual operation, is not influenced by factors such as weather and construction electricity, and improves the construction efficiency.

The application relates to the technical field of electronic equipment, and provides a learning machine, which comprises a host computer and a scanning pen, a first mounting piece is arranged on the side of the host computer, and the first mounting piece is provided with a sliding groove; the scanning pen is provided with a second mounting piece on the side, the second mounting piece is provided with a sliding part, the sliding part is suitable for being inserted into the sliding groove and moving relative to the sliding groove, so that the scanning pen is mounted on the side of the host computer. The first mounting piece and the second mounting piece are respectively arranged on the host computer and the scanning pen, and the scanning pen is mounted on the side of the scanning pen through the cooperation of the sliding groove and the sliding part, the influence of the thickness of the scanning pen on the thickness of the learning machine body is reduced, and the learning machine can keep a light and thin design.

A casting coating sagging property tester comprises a base, a placing piece is arranged on the base, a sample is arranged on the placing piece, and a scraping piece is movably arranged on the placing piece. When the sagging property of the casting coating is tested, a standard sample pressing template is provided, the blade coating surface of the molding sand casting template is ensured to be flat and compact in a pressing and scraping manner before casting, and the molding sand casting template can be protected through the provided mold, so that the service life of the molding sand casting template is prolonged, and the service life of the molding sand casting template is prolonged. And the problem of slag falling or damage of the molding sand casting template in the blade coating process is avoided, so that the sagging property test is not influenced. Wherein the dropped molding sand slag is doped in the coating due to the occurrence of the slag dropping problem, so that the uniformity of the blade coating thickness of the casting coating is influenced.

The utility model relates to photovoltaic technical field discloses a kind of battery assembly and its sealing structure. Sealing structure includes the first sealing member being arranged at corner, comprising: first surface, second surface, third surface, fourth surface and fifth surface, first surface is polygonal and has adjacent first side and second side, forms the first included angle same with the angle of photovoltaic laminated member corner;Second surface and third surface are perpendicular to first surface, respectively with first side and second side connection;Fourth surface includes the third side and fourth side forming second included angle, third side is connected with second surface, and the size of second included angle is equal with first included angle;Fifth surface is connected with fourth side, and fifth surface is suitable for adhering in third surface under external force. First sealing member local movable and have folding function, each sealing surface and photovoltaic laminated member are realized close contact by different means such as clamping, affixing, folding, and the final sealing position has overlapping portion, avoid water vapor into battery assembly, improve reliability.
