Embodiment Construction
[0020] A plastic bushing for an electric bed of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a plastic bushing for an electric bed, see Figure 4 , in the electric bed, the bending of the bed board needs to be realized by rotating parts, such as the shaft needs to rotate around the axis to complete the corresponding action, and the shaft should have at least two supports to support the shaft in order to realize the rotation, then in A shaft sleeve can be set between the shaft and the support to reduce the noise of the shaft when it turns back. The relative position between the shaft and the support should remain unchanged during use. Therefore, it is necessary to align the shaft and the support. Carry out limit;
[0021] see figure 1 , figure 2 , when assembling, the shaft sleeve should be set on the shaft. For this reason, the shaft sleeve should inclu...

The invention relates to a plastic shaft sleeve for an electric bed, which solves the problems of unreasonable structure and inconvenient use of the shaft sleeve in the prior art. The invention provides a plastic bushing for an electric bed, the body is provided with a shoulder part of an integral structure with the body, and the shoulder part acts as a position limiter, and is used to control the two rotating parts of the electric bed. Limit, and by setting the shoulder, the structure of the electric bed can also be simplified, and unnecessary limit devices can be avoided on the electric bed; in addition, the ring groove divides the shoulder into the first shoulder and the second shoulder. In addition to cooperating with other components to limit the position, the ring groove can also save the material for manufacturing the shaft sleeve, and by limiting the radius of the ring groove, it can avoid the ring groove from weakening the strength of the body; both the first shoulder and the second shoulder are opened The hole can reduce the cost of the shaft sleeve and can also play a role in heat dissipation, and setting a limit portion on the shaft sleeve is beneficial to the assembly of the shaft sleeve and the shaft.
Description
technical field [0001] The invention relates to an electric bed accessory, in particular to a plastic shaft sleeve for an electric bed. Background technique [0002] The electric bed is a kind of massage bed. The user can fold the bed board to the angle required by the user and fix it by operating the buttons during use. Therefore, the electric bed should have multiple rotating parts that can rotate with each other so that the bed board can be driven. The folding is carried out under the drive of the mechanism. [0003] In the prior art, in order to reduce the noise when the rotating parts of the electric bed rotate, a plastic bushing is generally set between two mutually rotating parts, that is to say, after the plastic bushing is set on the shaft, the shaft is connected to other structures. Cooperate, because the rotating part of electric bed generally adopts metal material to make, therefore, adopt plastic axle sleeve to be set on the axle and isolate two rotating parts,...
