A reel shaft end transition device for a retractable bed board

Abstract

The invention discloses a roller shaft end transition device for a retractable bedplate. The device includes rollers, a bedplate, and a side frame for support. The side frame is a supporting structure on both sides of a bed board, the bed board is a winding board, consisting of a plurality of parallel strips, A soft connection between strips, the strip plate is perpendicular to the side frame, bedplate fixed at one end, the other end is connected to the drive device after bypassing the roller, the driving device drives the bed plate to reel, the bed plate pulls the roller to displace, so thatthat guide transition plate is also include, comprising a guide rail and a slider, A guide rail is slidably and rotationally connected with a roller, By setting up the upper and lower guide rails extending into the edge of the bed plate, the bed plate can be easily shortened and compressed, and under the pull of the winding mechanism, the compression bed plate can easily bypass the side frame, and the roller can be restored after the roller is rolled, thereby effectively realizing the purpose that the bed plate can be supported on the side frame, and the bed plate can be contracted to bypassthe lower part of the side frame when the roller is approached.

Description

technical field [0001] The invention relates to the technical field of bed boards, in particular to a scroll shaft end transition device for a retractable medical bed board. Background technique [0002] With the growth of population aging, the growth of cancer diseases, and the growth of the number of seriously ill patients, the quality of clinical care for elderly patients has received more and more attention. Pressure sore is one of the very common geriatric diseases. Once a pressure sore occurs, it will not only bring pain to the patient, aggravate the condition, prolong the recovery time, and even endanger the life of the patient due to sepsis caused by secondary infection in severe cases. Therefore, pressure sore care has always been the top priority of basic nursing care. The existing bed body is generally a fixed bed board structure.

Problems solved by technology

Therefore, pressure sore care has always been the top priority of basic nursing care. The existing bed body is generally a fixed bed board structure. The bedding is used for a long time, and it is easy to get damp and breed bacteria, especially for patients with inconvenient activities. Under such circumstances, the replacement of quilts has become a big problem. One of the effective measures is to provide a coiled and combined bed board group. Through the cooperation of two bed boards at the same horizontal position, one is lowered and the other is raised alternately, so as to realize the support of the bed board. Replacement, so as to facilitate the operation of changing bedding above the bed board, such as image 3 As shown, there is a problem that is difficult to solve in the bed board device of this method. The bed board is a carrier for supporting the bedding, but it must also realize the operation of winding, unfolding and retracting. Without the effect of the bed board, even if it is designed as a one-way folding conveyor belt structure, its structure is too complicated, and the strength requirements are high. The concentrated force point of the supporting force will act on the end of the reel, and the middle part of the bed board is easily deformed, resulting in The bed board is uneven, so the bed board needs to be provided with support structures at both ends, and the support structure must also meet the requirements of the support strength. It is a difficult technical problem to not conflict with the support structure
