[0029] Please refer to Figures 1 to 5The utility model provides an operating bed 100, comprising a back plate 10 and a leg plate (not shown in the figure), one of the back plate 10 and the leg plate is provided with a first connecting portion 11, the first connecting portion 11 is connected with a locking mechanism 20, the locking mechanism 20 comprises a shell 21 and an elastic clamping member 22, the shell 21 is formed with a accommodating cavity 211, one side of the shell 21 has an opening 212, the elastic clamping member 22 is arranged in the accommodating cavity 211; the elastic clamping member 22 comprises a first clamping arm 221 and a second clamping arm 222 arranged opposite to each other, the first clamping arm 221 can be elastically deformed to approach or move away from the second clamping arm 222; the other of the back plate 10 and the leg plate is provided with a second connecting portion (not shown in the figure), the second connecting portion can be inserted into the accommodating cavity 211 through the opening 212, and clamped between the first clamping arm 221 and the second clamping arm 222.

[0030] Specifically, the operating bed 100 includes a backboard 10 and a legboard, and two connecting parts are arranged on the backboard 10 and the legboard. A locking mechanism 20 is provided on the first connecting part 11, and the locking mechanism 20 is provided with a shell 21 and an elastic clamping member 22. The elastic clamping member 22 is arranged in a accommodating cavity 211 of the shell 21. An opening 212 is provided on one side of the shell 21, so that the second connecting part can extend into the accommodating cavity 211 through the opening 212, and the second connecting part is clamped and locked by the elastic clamping member 22.

[0031] like Figure 3 The elastic clamping member 22 includes a first clamping arm 221 and a second clamping arm 222. The first clamping arm 221 can be elastically deformed. The first clamping arm 221 can be close to or away from the second clamping arm 222. The first clamping arm 221 and the second clamping arm 222 can clamp or release the second connecting portion to fix the back panel 10 and the leg panel.

[0032] The first clamp arm 221 can be elastically deformed by bending the first clamp arm 221 so that when the second connection part is plugged in, the first clamp arm 221 is elastically deformed and can be tightly pressed against the second connection part. Alternatively, the first clamp arm 221 can be pressed against by a hydraulic rod or other driving member so that the first clamp arm 221 can be close to or away from the second clamp arm 222 to clamp the second connection part. The specific method can be set according to actual needs.

[0033] By providing the second connection part of the elastic clamping member 22 clamping arm, the disassembly and assembly between the back plate 10 and the leg plate is facilitated, fewer parts are used, a lot of raw materials can be saved, the structure is simple, and the cost is low. In the prior art, the back plate 10 and the leg plate are also connected by screw locking, but this method is also inconvenient to disassemble and assemble. The solution of the utility model makes the disassembly and assembly between the back plate 10 and the leg plate convenient.

[0034] In addition, the first clamp arm 221 and the second clamp arm 222 are connected at one end away from the opening 212 through a connecting plate (not shown in the figure), and are integrally arranged with the connecting plate, so as to cooperate with the second connecting part to clamp or loosen the second connecting part to fix the leg plate and the back plate 10.

[0035] The technical solution of the utility model is to set an elastic clamping member 22. When the back plate 10 of the operating bed 100 is connected to the leg plate, the second connecting part can be inserted into the elastic clamping member 22. The elastic deformation of the first clamping arm 221 cooperates with the second clamping arm 222 to clamp the second connecting part, so that the leg plate and the back plate 10 are firmly connected together. This locking method has a simple structure, low cost, and is easy to disassemble and assemble.

[0036] In one embodiment of the utility model, an opening 213 is provided on the shell wall of the shell 21 facing the first clamping arm 221; the elastic clamping member 22 also includes a wrench block 223, the wrench block 223 is rotatably connected to the opening 213 of the shell 21 and is arranged opposite to the first clamping arm 221, and the surface of the wrench block 223 facing the first clamping arm 221 has a clamping portion 2231, and the wrench block 223 is rotated to allow the clamping portion 2231 to clamp or loosen the first clamping arm 221.

[0037] It is worth noting that an opening 213 is also provided on the shell 21, and the opening 213 is arranged near the first clamping arm 221. A wrench block 223 is provided at the opening 213. The wrench block 223 is located on the side of the first clamping arm 221 away from the accommodating chamber 211, and a clamping portion 2231 is convexly provided on the surface of the wrench block 223 near the first clamping arm 221. By rotating the wrench block 223, the clamping portion 2231 of the wrench block 223 can act on the first clamping arm 221 to clamp the first clamping arm 221 or loosen the first clamping arm 221. That is, by setting the wrench block 223, the first clamping arm 221 can be clamped, so that the second connecting portion can be better clamped between the first clamping arm 221 and the second clamping arm 222, thereby fixing the head plate and the back plate 10 to meet the locking requirements.

[0038] When unlocking is required, the wrench block 223 only needs to be pushed away from the first clamping arm 221, and the clamping portion 2231 will be away from the first clamping arm 221. The first clamping arm 221 is relaxed, and the second connecting portion can be taken out, so that the head plate and the back plate 10 can be unlocked for disassembly, which is very convenient for disassembly and assembly.

[0046] It is worth noting that Figure 3 The wall surface at the other end of the wrench block 223 and the wall surface on the other side of the opening 213 are both configured as arc surfaces. This matching method can prevent wear when the wrench block 223 rotates, making it easier for the wrench block 223 to rotate and tighten the first clamping arm 221.

[0047] In an embodiment of the present invention, rotating parts 2233 are respectively provided on both sides of the wrench block 223 , and rotating shafts 214 are provided on both sides of the housing 21 close to the opening 213 , and the rotating parts 2233 are rotatably connected to the rotating shafts 214 .

[0048] In detail, rotating parts 2233 are provided on both sides of the wrench block 223, and rotating shafts 214 are provided on both sides of the opening 213 of the shell 21. The wrench block 223 is rotatably connected to the two rotating shafts 214 through the two rotating parts 2233, respectively, which can support the wrench block 223 so that the wrench block 223 can rotate stably. This method is wear-resistant and easy to assemble and maintain.

[0049] In an embodiment of the present invention, the rotating portion 2233 and the rotating shaft 214 are both located inside the housing 21 .

[0050] It is worth noting that the rotating portion 2233 is arranged on both sides of the surface of the wrench block 223 facing the first clamping arm 221, and the rotating shaft 214 is connected to the inner wall of the housing 21 close to the opening 213, and the rotating shaft 214 partially extends to the opening 213 to facilitate cooperation with the rotating portion 2233. The rotating portion 2233 and the rotating shaft 214 are both arranged inside the housing 21, so as to keep the surface of the device flat and facilitate the installation of the wrench block 223.

[0051] In an embodiment of the present invention, the locking mechanism 20 is fixed to the first connecting portion 11 by welding.

[0052] Specifically, the locking mechanism 20 is welded on the first connecting portion 11 to form a firm connection, so that the locking mechanism 20 can cooperate with the second connecting portion more stably. The welding method is simple to operate and low in cost.

[0053] In an embodiment of the present invention, the first connecting portion 11 is provided with a plugging hole (not shown in the figure), the housing 21 is disposed in the plugging hole, and the opening 212 of the housing 21 is arranged toward the plugging hole.

[0054] In detail, a plug-in hole is provided on the first connecting part 11, which is convenient for setting the shell 21 in the plug-in hole, facilitating the installation and fixation of the shell 21, and making the locking mechanism 20 more stably connected to the first connecting part 11.
