DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-7 The utility model provides a technical solution: an electric nursing bed with a backrest adjustable at multiple angles, comprising a bed body 1, a backrest 2, an electric telescopic rod 3, a backrest adjustment mechanism 4, a movable connecting plate 5, a gear 6, a fixed connecting rod 7, an auxiliary block 8, a guardrail 9, a support block 10, a limit rod 11, a fixed groove 12, a fixed connecting frame 13, a connecting side plate 14, a fixed connecting block 15, a spring 16 and a fixed pull ring 17.

[0035] When using the electric nursing bed with multi-angle adjustable backrest, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the right end of the bed 1 is rotatably connected with the backrest 2, and a backrest adjustment mechanism 4 is provided at the connection between the bed 1 and the lower end of the backrest 2. At the same time, the backrest adjustment mechanism 4 includes an active connecting plate 5 fixedly installed at the output end of the electric telescopic rod 3, a gear 6 fixedly installed at the lower left end of the backrest 2, a fixed connecting rod 7 for connection and an auxiliary block 8 fixedly connected to the lower end of the backrest 2. During use, the electric telescopic rod 3 installed at the lower end of the bed 1 can be started, and the electric telescopic rod 3 can push the active connecting plate 5 to move slowly to the right, and the active connecting plate 5 is meshed with the gear 6, thereby driving the backrest 2 to flip over at the short end of the bed 1, and the backrest 2 and the bed 1 are adjusted as shown in the figure. Figure 1 The state shown is transformed into Figure 5 The state shown in the figure makes it easy for the patient to lean on the nursing bed during use, which is very convenient to use. Moreover, when the movable connecting plate 5 is in the process of telescopic movement, the right end of the movable connecting plate 5 is fixedly connected to the fixed connecting rod 7, and the movable connecting plate 5 drives the fixed connecting rod 7 to slide with the auxiliary block 8, thereby improving the stability of the movable connecting plate 5 in the process of telescopic movement;

[0036] In addition, if Figure 1 , Figure 6 and Figure 7 As shown, guardrails 9 are provided on both the front and rear sides of the bed 1. The guardrails 9 can provide good protection for patients and prevent them from falling on the nursing bed. When the bed is not in use or when the patient needs to get on or off the bed, the fixed pull ring 17 can be pulled, and the fixed pull ring 17 drives the fixed connection frame 13 to move at the left end of the bed 1. The fixed connection frame 13 moves on the outside of the connecting side plate 14, and slides between the fixed connection frame 13 and the fixed connection block 15, thereby improving the stability of the fixed connection frame 13 moving at the left end of the bed 1.

[0037] At this time, the fixed connection frame 13 squeezes the spring 16, causing the spring 16 to undergo elastic deformation, and the fixed connection frame 13 moves out of the fixing slot 12, thereby releasing the limit on the limit rod 11, and the limit rod 11 is fixedly connected to the lower left end of the guardrail 9, and then the guardrail 9 is turned downward to 180 degrees, and the guardrail 9 and the support block 10 are rotated, so that the guardrail 9 and the bed 1 are spaced apart. Figure 1 The status shown is converted to Figure 2 In the state shown, after the flipping is completed, the fixed pull ring 17 is directly released, and the spring 16 restores its elastic deformation, driving the fixed connection frame 13 to be inserted into the fixed groove 12 at the corresponding position on the limiting rod 11, thereby facilitating the limiting of the guardrail 9 and the bed 1.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
