The invention discloses a linkage system based on a sliding door and window. The sliding door and window is formed through the connection of a board-like movable object and a board-like linkage object. The linkage system comprises a connecting board presenting an S-shaped structure, a slide groove assembly, a slide rail assembly and a positioner, wherein the slide rail assembly comprises a first slide rail and a second slide rail, and the first slide rail and the second slide rail are respectively arranged at two ends of the connecting board; the slide groove assembly comprises a first slide groove and a second slide groove; the first slide groove is formed in the board-like movable object, and the second slide groove is formed in the board-like linkage object; the first slide groove and the second slide groove face to the same direction; the first slide groove formed in the board-like movable object is correspondingly connected with the first slide rail; the second slide groove formed in the board-like linkage object is correspondingly connected with the second slide rail; the positioner is a fixed piece in a square block shape, and is fixedly mounted in the second slide groove in the linkage object or the first slide groove in the movable object. The linkage system disclosed by the invention can realize the phenomenon that the overlapped area of a door leaf is the smallest when the sliding door and window is opened, namely the sliding door and window is completely opened, so that the maximum area division space of the door leaf is sufficiently utilized.

The invention discloses a strapless protective shoe for outdoor climbing sports, which comprises a front paw body, a rear paw body, a fixer fixed on the rear paw body, and a shoe clip fixed on the end of the rear paw body away from the front paw body. A positioning mechanism is installed on the top of the front claw body, and a telescopic rotation mechanism is arranged between the front claw body and the rear claw body. This strapless protective shoe for outdoor climbing sports is different from the prior art in that it is based on a spring without On the basis of the straps, when the size of the user's feet is different, the relative movement and relative deflection of the front paw body and the rear paw body can be effectively realized to ensure the normal wearing and use of the protective shoes, and the toes can obtain sufficient grip strength, so as to ensure normal, stable and efficient walking and climbing. At the same time, it can effectively locate the actual size of the user's toe, so as to cooperate with the fixer to effectively avoid the problem of protective shoes falling off during walking, so as to more effectively ensure the safety of the shoes. Stable and efficient use of the body.

The invention discloses a sealing device for a sliding rail of a numerical control machine tool. The sealing device comprises a shell, an adjusting device, a base, a rear baffle and a rotating shaft. A front baffle is installed at the left side of the shell, and an abrasion-resistant pad is installed on the lower surface of the front baffle; supporting columns are installed on the shell, the adjusting device is installed on the shell, and an adjusting groove is formed in the surface of the adjusting device; fixing rods are installed on the right side of the adjusting device, the base is installed under the shell, a fastening adjusting rod is installed under the base, and the rear baffle is installed on the right side of the shell; a safety lock groove is formed in the right surface of the rotating shaft, and a fixed screw is installed on the right surface of the rear baffle; and a sliding rail groove is formed in the right surface of the rear baffle, and an engaging groove is formed in the sliding rail groove. The supporting columns are each of a stainless steel compression-resistant structure, and excessive abrasion to the supporting columns can be avoided; and the device cannot be damaged after being used for a long time, and the service life of the device is prolonged.

The invention belongs to the technical field of reactive dyes, and in particular relates to a navy blue reactive dye formulation with high light fastness, high light-perspiration composite color fastness and high wet rubbing color fastness. The invention has navy blue reactive dyes used for dyeing fabrics to obtain high single-color light fastness, high perspiration fastness to acid sweat CS color change, cotton staining and perspiration fastness to alkali sweat CS color change grade, high resistance to dry and wet friction The advantage of high intensity, and the cost of navy blue reactive dyes is low, which can improve the brightness of clothing fabrics. Compared with vat (shihlin) dyes, the pollution is lower, and the pressure of wastewater treatment is lower. The overall production and application process is reasonable and effective, simple and fast, and in All cotton fabrics, cotton fiber and polyester fiber blended fabrics, cotton fiber and polyester fiber blended fabrics can be used efficiently and stably on these three types of fabrics.

The invention discloses a functional cushion for hand surgery, which belongs to the field of medical rehabilitation nursing equipment. The big arm supporting pad of the invention is movably connected to one side of the end of the forearm supporting pad. The big arm supporting pad is horizontally provided with a clamping rotation mechanism along the middle part of the side of the forearm supporting pad. Between the arm bottom plate and the forearm supporting rotating plate, the ends of the upper and lower sides of the clamping supporting connecting plate are respectively hingedly connected to the forearm supporting rotating plate and the supporting arm bottom plate, and the supporting plate adjustment mechanism is arranged on the supporting arm bottom plate and the forearm Between the supporting rotating plates, the forearm limit mechanism is arranged on both sides of the forearm supporting rotating plates, and the rehabilitation training mechanism is arranged on the upper side of the end of the forearm supporting rotating plates. The invention has reasonable structural design, convenient operation and use, can efficiently and conveniently adjust the supporting position according to the needs of the patient's arm for medical use, realizes the stable and comfortable placement and support of the patient's arm, and has the function of arm rehabilitation training to meet the needs of medical use.
