Referring to fig. 1 to 4, an embodiment of the present invention provides a swing arm for a nursing bed, including: the base 200 is provided with an accommodating cavity 201, and the accommodating cavity 201 is of a top opening structure. The accommodating cavity 201 is provided with a shaft hole, the shaft hole is provided with two first shaft holes 270 and second shaft holes 260, and the shaft hole is matched with a rotating shaft on the nursing bed to enable the base 200 to be fixedly connected with the rotating shaft. It is understood that the connection portion of the shaft hole and the rotating shaft has a shaft sleeve, including a first shaft sleeve 230 and a second shaft sleeve 220. In the actual operation in-process, thereby the staff waves the rocking arm and drives the pivot and rotate and then reach the purpose of adjustment medical bed, consequently rocking arm, axle sleeve and pivot three fixed connection, and the axle sleeve is installed including using interference fit, using modes such as binder or splined connection in the middle of the rocking arm, and the fixed connection of axle sleeve and pivot also can be through crossing modes such as lock, interference fit or key-type connection. The material of axle sleeve can be rubber, plastics or metal material, and the preferred nylon plastics material of this technical scheme, simple structure is light, can keep good durability in the dismouting many times.

The cover plate 100 covers the base 200. Wherein, the cover plate 100 is provided with the buckle 130, the accommodating cavity 201 is provided with the clamping piece 240, and the buckle 130 is matched and clamped with the clamping piece 240, so that the cover plate 100 is connected with the base 200. Referring to fig. 4, the buckle 130 is embedded into the clip 240, and the buckle 130 and the clip 240 are elastically deformed in different degrees in the embedding and mounting process, so that the buckle 130 and the clip 240 are made of elastic materials, including nylon material PA66, polyethylene, polypropylene, ABS plastic, etc., and have good toughness and elasticity, which is beneficial to the durable fastening and low cost.

Considering that the base 200 is a main stressed component in use, the base 200 is preferably made of an aluminum alloy material and is manufactured by casting, so that the base has light weight and good rigidity, and is beneficial to good transmission effect and good durability. The cover plate 100 is preferably made of plastics such as polyethylene and ABS, so that the rocker arm is light and easy to use, the elasticity of the plastics is high, the plastic deformation is not easy to generate after repeated assembly and disassembly, and the use durability is improved.

Optionally, the clip 130 includes a fixing portion 125 and a clip portion 120, the fixing portion 125 is fixedly connected with the cover plate 100, and the clip portion 120 is connected with the fixing portion 125. Convenience and the steadiness of installation when considering actual installation, joint portion 120 will have better elasticity and elastic deformation, therefore joint portion 120 can have hollow out construction, produces great deflection when the lock, kick-backs when joint portion 120 imbeds joint piece 240 inside completely, and the cooperation position has great magnitude of interference and makes buckle 130 can not pulled out easily this moment, reaches the purpose of connecting firmly.

It is understood that the clip portion 120 is used for engaging with the clip 240 mounted on the base 200, the fixing portion 125 is used for fixing the clip 130 on the cover 100, and the fixing manner may be interference fit, adhesive bonding, or screwing.
