This invention relates to the field of bathing aids technology and discloses an improved shower chair structure, including a chair frame assembly, a seat, a backrest, and armrest assemblies. The chair frame assembly is formed by hinged front and rear frames, and a load-bearing structure for mounting the seat is provided between the chair frame assemblies. The load-bearing structure includes a first pivot support at the hinge of the front and rear frames and a second pivot support composed of a first load-bearing column, a second load-bearing column, and a connecting rod. One end of the connecting rod is pivotally connected to the seat by a bolt, and the other end is fitted onto the first load-bearing column. The top end of the connecting rod is placed in a connecting rod limiting groove, and the connecting rod also has a pointed protrusion that abuts against the end of the connecting rod limiting groove when folded. This solves the technical problem in the prior art that shower chairs cannot stand freely after folding and sometimes open on their own, causing safety issues. It provides a new shower chair structure that is simple in structure, low in cost, ergonomically designed, sturdy in support, safe and stable in opening and closing, and healthy and comfortable.

This application relates to a combined protection structure for treating unstable rock slopes, comprising multiple anti-slide piles anchored to the slope and a passive protective net. The anti-slide piles include a steel cage and a concrete layer. The passive protective net includes multiple columns and multiple protective net panels. The columns are all anchored to the lower edge of the slope and distributed along the length of the lower edge. The protective net panels are connected to at least two columns. This application can improve the treatment effect of unstable rock slopes and reduce the threat to buildings below.

The utility model relates to the technical field of temperature uniformizing plates, and particularly provides a temperature uniformizing plate with a specially arranged wick, which comprises an upper cover plate, a lower cover plate and a lower cover plate, the upper liquid absorbing core is arranged in the upper accommodating groove; a plurality of upper fixing holes are formed in the upper liquid absorbing core; the lower liquid absorbing core is provided with a plurality of lower fixing holes which are in one-to-one correspondence with the upper fixing holes; the lower cover plate is provided with a lower accommodating groove, and the lower liquid absorbing core is arranged in the lower accommodating groove; the plurality of backflow supporting columns are arranged in the plurality of lower fixing holes and the plurality of upper fixing holes; the two ends of the backflow supporting columns abut against the upper cover plate and the lower cover plate respectively. A multi-dimensional channel is constructed through the axial backflow gaps and the radial backflow gaps, the capillary suction force of the backflow supporting columns is enhanced, a working medium evaporated and rising to the upper cover plate in the heating area can be efficiently drained to the heating area of the lower cover plate, rapid circulation is formed, and therefore the heat resistance is remarkably reduced, and the temperature equalizing capacity is improved; the problem that a traditional columnar supporting structure can only provide mechanical supporting and cannot accelerate working medium backflow is solved.

This utility model discloses an adjustable pressure ulcer prevention support, relating to the field of medical care device technology. The adjustable pressure ulcer prevention support includes a support plate and connecting plates. Two sets of connecting plates are provided, and the connecting plates have an arched structure. The two connecting plates are arranged crosswise, with the intersection point rotatably connected by a pin, forming a cross frame. The four ends of the cross frame are mounted on the support plate, and one end of the connecting plate can slide on the support plate. The distance between the two support plates is adjusted by changing the cross angle between the connecting plates. This utility model features two relatively rotatable arched connecting plates. This relative rotation allows adjustment of the distance between the two support plates, enabling the support size to be modified according to needs. Furthermore, compared to a typical parallel straight-bar frame, the resulting arched cross frame can support bed sheets to a higher position with more even support distribution, providing better support.

The utility model discloses a kind of roller pressure door sill structures of stable energy absorption, including outer plate, inner plate and energy absorption assembly;The section of outer plate and inner plate is all several Chinese character shape structure, and the opening end of both is welded after butt joint at flange edge, and the door sill cavity with the section of rectangular is formed;The energy absorption assembly is set in door sill cavity, and is formed by first roller pressure piece, second roller pressure piece stitch welding, forms first energy absorption cavity and second energy absorption cavity, and first energy absorption cavity is located at the outside of second energy absorption cavity;The section of first energy absorption cavity is less than the section of second energy absorption cavity;First energy absorption cavity, second energy absorption cavity gradually increase in cavity section from outside to inside in along the transverse direction of car body.The utility model has the characteristics of low cost, energy absorption stability, good safety.
