The first bed plate beams 113 are linearly arrayed and fixed between the two first long side beams 111, and the bed plate 140 of the upper layer is placed on the first bed plate beams 113. The embodiment of the application is provided with a clamping groove 300 on both sides of the bottom surface of the first long side beam 111 and on both sides of the top surface of the second long side beam 121. The side ladder 200 comprises two support beams 210 and a plurality of step beams 220 linearly arrayed and fixed between the two support beams 210. The first connecting beam 230 and the second connecting beam 240 are fixed between the two support beams 210. The top surface of the first connecting beam 230 abuts against the bottom surface of the first long side beam 111, and the bottom surface of the second connecting beam 240 abuts against the top surface of the second connecting beam 240. The adjusting groove 410 is formed in the first connecting beam 230 and the second connecting beam 240. The limiting groove 420 is formed in the top surface of the first connecting beam 230 and the bottom surface of the second connecting beam 240, and the limiting groove 420 is in communication with the adjusting groove 410. The groove width of the adjusting groove 410 is greater than that of the limiting groove 420. The adjusting plate 510 is slidably connected in the adjusting groove 410. The clamping plate 520 is fixed to one side of the adjusting plate 510 close to the limiting groove 420, and the clamping plate 520 penetrates through the limiting groove 420. The adjusting mechanism 600 is arranged in the support beam 210, and is used for controlling the clamping plate 520 to be clamped into the clamping groove 300.

[0035] Specifically, referring to Figure 5 Figure 9 The adjusting mechanism 600 comprises the wire spool 610 rotatably connected between the two support beams 210. The traction wire 620 is fixed to the wire spool 610, and one end of the traction wire 620 away from the wire spool 610 is fixed to the clamping plate 520. The wire groove 211 is formed in the middle of the support beam 210. Each clamping plate 520 is fixed with the traction wire 620 on both sides, and the traction wire 620 is located in the wire groove 211. A plurality of first compression springs 630 are fixed to one side of the clamping plate 520 away from the limiting groove 420, and one end of the first compression spring 630 away from the clamping plate 520 is fixed to the groove wall of the adjusting groove 410. The drive assembly 640 is installed on the side surface of the support beam 210 to drive the rotation of the wire spool 610.

[0036] Further, referring to Figure 5 ​The driving assembly comprises a connecting box 641 mounted on one side of the support beam 210, a driving worm 642 rotatably connected in the connecting box 641, a driving worm wheel 643 fixedly connected with the driving worm 642 on the spool 610, and a rotating disc 644 fixedly connected at the shaft end of the driving worm 642.

[0037] In the following, further introduction is made in combination with a specific use scene. When the user of the apartment bed feels that the position of the side ladder 200 is inconvenient for getting on and off the bed, or needs to change the position of the apartment bed, the rotating disc 644 can be rotated, the spool 610 is driven to rotate under the meshing cooperation of the driving worm 642 and the driving worm wheel 643, the traction wire 620 is driven to start to be wound, the adjusting plate 510 in the first connecting beam 230 and the second connecting beam 240 is moved towards the direction of compressing the first compression spring 630, the clamping plate 520 is continuously away from the clamping groove 300, until the clamping plate 520 is completely separated from the clamping groove 300, the locking between the side ladder 200 and the first long side beam 111 and the second long side beam 121 is released. Since the spool 610 is driven to rotate through the meshing cooperation of the driving worm wheel 643 and the driving worm 642, the self-locking property of the meshing cooperation of the worm wheel and the worm can be used to ensure that the adjusting plate 510 will not be automatically moved away from the first compression spring 630 under the action of the first compression spring 630 after the locking of the side ladder 200 is released, so that the side ladder 200 can be more convenient to change.

[0038] Further, after the locking of the side ladder 200 is released, the side ladder 200 can be moved to the position to be changed, the clamping plate 520 is positioned corresponding to the clamping groove 300 on the first long side beam 111 and the second long side beam 121, then the rotating disc 644 is reversely rotated, the spool 610 is reversely rotated to loosen the wire, and under the action of the first compression spring 630, the adjusting plate 510 is gradually moved away from the first compression spring 630, the clamping plate 520 is inserted into the clamping groove 300, so that the side ladder 200 is re-locked, that is, the position of the side ladder 200 is changed, which is more convenient and does not need to use tools.

[0039] The first connecting beam 230, the second connecting beam 240, the adjusting groove 410, the limiting groove 420, the adjusting plate 510, the clamping plate 520 are arranged, and the clamping groove 300 is arranged on the bottom surface of the first long side beam 111 and the top surface of the second long side beam 121, so that the side ladder 200 can be stably installed between the first long side beam 111 and the second long side beam 121; when it is necessary to replace the position of the side ladder 200, the clamping plate 520 is controlled to move away from the clamping groove 300 through the adjusting mechanism 600, so that the locking of the side ladder 200 is released, and the position of the side ladder 200 can be replaced. Overall, the position of the side ladder 200 can be conveniently adjusted, the adaptability of the position of the apartment bed is improved, and the convenience of replacing the position of the side ladder 200 of the apartment bed is improved.

[0040] With reference to Figure 2 and Figure 3 , as a specific embodiment of the present application, the step beam 220 is a hollow rod, and the spool 610 is coaxially connected in one of the step beams 220. In this way, the spool 610 does not have to be exposed, so that the overall appearance of the side ladder 200 can be ensured, and the use stability and safety of the spool 610 can also be ensured.

[0041] With reference to Figure 3 、 Figure 7 、 Figure 9 、 Figure 10 , as a specific embodiment of the present application, the L-shaped connecting plate 710 is fixedly connected to the side surface of the second connecting beam 240, the mounting block 720 is fixedly connected to the connecting plate 710, the sliding groove 730 is arranged on the top of the mounting block 720, the positioning block 740 is slidably connected in the sliding groove 730, the top end of the positioning block 740 is hemispherical, the second compression spring 750 is arranged between the positioning block 740 and the sliding groove 730, the positioning groove 760 is arranged on both sides of the bottom surface of the second long side beam 121, and the limiting track groove 770 is arranged on the bottom surface of the second long side beam 121, and the limiting track groove 770 is communicated with the two positioning grooves 760 at both ends.

[0042] In combination with a specific use scenario, when the installation position of the side ladder 200 needs to be changed, if the change of the position of the side ladder 200 is performed on the same second long side beam 121, that is, the side ladder 200 is changed from one end of the second long side beam 121 to the other end, the side ladder 200 does not need to be completely removed, and only the clamping plate 520 needs to be driven by the driving assembly 640 to be away from the clamping groove 300, so that the locking of the side ladder 200 is released, and then the side ladder 200 can be pushed to move along the second long side beam 121. In this process, the positioning block 740 will pass through the positioning groove 760 to reach the limiting track groove 770 and move along the limiting track groove 770. Here, when the side ladder 200 passes from the positioning groove 760 to the limiting track groove 770, the second compression spring 750 is further compressed; when the side ladder 200 reaches the specified installation position, the positioning block 740 will be clamped into the positioning groove 760 under the action of the second compression spring 750, at this time, the side ladder 200 cannot be pushed in the same direction. Then the clamping plate 520 can be clamped into the clamping groove 300 by the driving assembly 640, so that the side ladder 200 is locked again. Overall, the convenience of changing the position of the side ladder 200 is improved.

[0043] With reference to Figure 4 , Figure 5 and Figure 7 , as a specific embodiment of the present application, in order to improve the installation stability of the side ladder 200, at least two clamping plates 520 are arranged on each adjusting plate, and the number of clamping grooves 300 on the bottom surface of the first long side beam 111 and the number of clamping grooves 300 on the top surface of the second long side beam 121 should also be the same as the number of clamping plates 520.

[0044] In combination with a specific use scenario, by increasing the number of clamping plates 520, the connection area between the side ladder 200 and the first long side beam 111 and the second long side beam 121 is equivalent to being increased, the connection strength between the side ladder 200 and the first long side beam 111 and the second long side beam 121 is improved, and the overall installation stability of the side ladder 200 is further improved, which ensures the safety of the user during the process of getting on and off the bed to a certain extent.

[0045] With reference to Figure 1 and Figure 3 , as a specific embodiment of the present application, a plurality of plug-in grooves 1111 are arranged on the top surface of each first long side beam 111, and a plurality of plug-in columns 131 corresponding to the plug-in grooves 1111 are fixedly connected to the bottom of the guardrail 130.

[0046] In combination with a specific use scenario, the guardrail and the side ladder 200 restrict the placing direction of the apartment bed, and the position of the side ladder 200 can be changed in the above embodiment. In order to further facilitate the placing of the apartment bed, a row of plug-in slots 1111 is formed on the top surface of the two first long beams 111 of the bed frame 110, and the plug-in column 131 is fixedly connected to the plug-in slot 1111 at the bottom of the guardrail 130. In this way, the position of the guardrail 130 does not need to be deliberately paid attention to by the moving worker, and even if the placing is wrong, the guardrail 130 can be installed on the other first long beam 111 by being pulled out, thereby improving the convenience of placing the apartment bed.
