DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] like Figures 1 to 6 As shown, a storage bed of the utility model comprises an assembled bed frame 1 and two hydraulic arms 2.

[0030] The assembled bed frame 1 comprises a bed board structure 11, a bed head structure 12, a bed foot structure 13 and two symmetrically arranged bed side structures 14; the bed head structure 12 and the bed foot structure 13 are arranged head to tail, and the two bed side structures 14 are detachably arranged on both sides of the bed head structure 12 and the bed foot structure 13, so as to enclose a bed body A; the bed board structure 11 is located inside the bed body A;

[0031] The two hydraulic arms 2 are respectively installed on the inner sides of the two bed side structures 14. The hydraulic arms 2 of this embodiment are arranged near the head of the bed B. The two hydraulic arms 2 are also connected to the bed board structure 11 to control the lifting and lowering of the tail of the bed board structure 11. The hydraulic arms 2 of this embodiment adopt the existing technology, and its specific structural principle will not be repeated here.

[0032] The bed side structure 14 is disconnected at the installation position of the hydraulic arm 2 and is divided into two parts: a first bed side structure 141 and a second bed side structure 142. The first bed side structure 141 and the second bed side structure 142 are detachably connected and fixed to each other and are connected to the hydraulic arm 2 at the same time; both sides of the bed board structure 11 are disconnected at the connection position of the two hydraulic arms 2 and are divided into two parts: a first bed board structure 111 and a second bed board structure 112. The first bed board structure 111 and the second bed board structure 112 are detachably connected and fixed to each other and are connected to the two hydraulic arms 2 at the same time.

[0033] Different from the existing structure that is disconnected in the middle of the bed body A, the bed side structure 14 and the bed board structure 11 of this embodiment are disconnected at the installation point of the hydraulic arm 2, and the hydraulic arm 2 is usually installed at the position of the bed body A near the head B. While meeting the requirements of detachable storage and reducing the packaging volume, the disconnected parts of the assembled bed side structure 14 and the bed board structure 11 can be directly connected and fixed to the hydraulic arm 2, which not only saves installation steps and makes assembly more convenient, but also when the hydraulic arm 2 controls the lifting and lowering of the bed board structure 11, the hydraulic arm 2 directly acts on the two first bed board structures 111 and the second bed board structure 112 at the disconnected part, and can drive the two disconnected parts to move together at the same time, thereby improving the lifting stability and improving the structural stability of the bed body A.

[0038] like Figure 3 As shown, the first bedside structure 141 and the second bedside structure 142 are both frame structures, and a plurality of bedside support rods 143 are provided inside the first bedside structure 141 and the second bedside structure 142; a bedside connecting rod 144 is provided at a position close to each other of the first bedside structure 141 and the second bedside structure 142, and the two bedside connecting rods 144 are respectively locked and fixed with the head and tail sides of the bottom rod 21 of the hydraulic arm 2. In this way, the first bedside structure 141 and the second bedside structure 142 can be installed and connected while installing the hydraulic arm 2, saving installation steps.

[0039] Two bottom connecting rods 145 may be further provided between the first bed side structure 141 and the second bed side structure 142 for reinforced fixation; the two bottom connecting rods 145 are spaced apart in the head and tail directions, and both ends of the bottom connecting rods 145 are respectively locked to the bottom of the first bed side structure 141 and the second bed side structure 142.

By providing the embedded pipe fitting 117, the connection strength of the first bedside rod 114 and the second bedside rod 116 can be increased.
