[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5It can be seen that since the No. 1 plate 2, the No. 2 plate 3 and the middle plate 1 are all slidably connected through the support plate 7 and the support groove 8, the linkage plate 503 and the support frame 501 and the rotating plate 502 are all rotationally connected through the pin shaft, and the rotating plate 502 and the middle plate 1 are rotationally connected through the support shaft 504, the rotating plate 502 can be deflected with the support shaft 504 as the axis under the action of the linkage plate 503 by pulling the No. 1 plate 2 or the No. 2 plate 3 to one side, and at the same time, the No. 1 plate 2 and the No. 2 plate 3 are extended to both sides of the middle plate 1, thereby realizing the adjustment of the length of the bed, which is convenient for use by people with taller heights, expands the scope of application, and improves the use effect of the bed.
[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It can be seen that a locking mechanism 6 extending to the inside of the middle plate 1 is provided at one end of the rotating plate 502, and the locking mechanism 6 is composed of a locking groove 601, a locking plate 602, a support spring 603, a limit frame 604, an inclined push plate 605, an electric push rod 606 and a vertical plate 607. The bottom end of the rotating plate 502 is welded with a vertical plate 607 and a limit frame 604 in sequence from left to right, and an electric push rod 606 is installed on one side of the vertical plate 607. An inclined push plate 605 penetrating the limit frame 604 is provided on one side of the electric push rod 606. A battery is installed on the bottom end of the rotating plate 502 above the electric push rod 606, and the electric push rod 606 is connected to the battery through a power cord;
[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It can be seen that since the locking plate 602 is provided with an inclined surface on one side close to the inclined push plate 605, when the electric push rod 606 is working and extending, the inclined push plate 605 pushes the locking plate 602 to move vertically upward and engages with the locking groove 601, thereby achieving locking of the rotating plate 502 after displacement, so as to prevent the adjusted bed from extending or contracting in the length direction due to external force during use, thereby increasing the stability after adjustment.
[0027] See also Figure 1 and Figure 2 It can be seen that a support groove 8 is provided on the outer surface of the middle plate 1, and a support plate 7 is welded to the inner surfaces of the No. 1 plate 2 and the No. 2 plate 3. The No. 1 plate 2, the No. 2 plate 3 and the middle plate 1 form a sliding structure through the support plate 7 and the support groove 8, which can play a supporting and limiting role, thereby increasing the stability of the No. 1 plate 2 and the No. 2 plate 3 during the sliding process.

Since the locking plate 602 and the rotating plate 502 are elastically connected via the support spring 603, the oblique push plate 605 moves horizontally and resets during the operation and contraction of the electric push rod 606, and at the same time, the locking plate 602 moves vertically downward and resets under the action of the support spring 603 and separates from the locking groove 601, thereby releasing the lock on the rotating plate 502.
[0029] The working principle of the utility model is as follows: when the extendable bed is used, the electric push rod 606 is operated and retracted, so that the inclined push plate 605 moves horizontally and resets, and at the same time, the locking plate 602 is vertically moved downward and reset and separated from the locking groove 601 under the action of the support spring 603. At this time, the rotating plate 502 can be deflected with the support shaft 504 as the axis under the action of the linkage plate 503 by pulling the No. 1 plate 2 or the No. 2 plate 3 to one side, and at the same time, the No. 1 plate 2 and the No. 2 plate 3 are extended to both sides of the middle plate 1, thereby realizing the adjustment of the length of the bed, and then it is convenient for people with taller heights to use.
