Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the electric pushrod fixed structure of the present embodiment is described in further detail.
The overall structure schematic diagram that Figure 1 shows that electric bathing chair, is fixedly installed electric pushrod 6 at the back side of its chair back 2, at present the normal fixed form using be bolted fixing.The defect of this fixed form is long-term easy the becoming flexible that use, and causes often needing repairing, and be also shorter the service life of bath chair.
In order to solve above-mentioned technological deficiency, a kind of electric pushrod fixed structure of the present embodiment as shown in Figure 2 and Figure 3, comprises upper cover 51 and lower cover 52, and its lower cover 52 is bolted to connection on the chair back 2, and 51 of its upper covers fasten mutually with lower cover 52.On above-mentioned upper cover 51, be provided with the first container cavity 511, lower cover 52 is provided with the second container cavity 523, after its first container cavity 511 and the second container cavity 523 fasten for holding electric pushrod 6.
In the present embodiment, except above-mentioned being threaded, its lower cover 52 is also fixedly connected with by latch 54 with the chair back 2.On its chair back 2, be provided with the pin-and-hole 21 adapting with latch 54, on lower cover 52, be provided with accordingly pin joint hole 521, and above-mentioned pin-and-hole 21 be vertical with the axis of the first container cavity 511, the second container cavity 523 with the axis in pin joint hole 521.The fixing mode fixedly combining with bolt of this latch, make the electric pushrod fixed structure of the present embodiment more solid and reliable, even if wherein a kind of fixed form lost efficacy, the continuation that also can not affect bath chair is used, and has greatly extended the service life of bath chair.
Further, as shown in Fig. 4, Fig. 6, its latch 54 comprises bearing pin 541 and is located at bearing pin 541 upper protruding blocks 542, holds and be provided with on pin-and-hole 21 and pin joint hole 521 groove 522 that above-mentioned projection 542 passes through, and is also provided with cavity 526 at the inner end in its pin joint hole 521.Using latch 54 while connecting, first, projection 542 is alignd with groove 522, by latch 54 smoothly by insertion in pin-and-hole 21 and pin joint hole 521; In the time being inserted to deep-seated and putting, projection 542 is in cavity 526.Now, rotation latch 54, staggers projection 542 and groove 522 mutually, and what so latch 54 can be stable is fixed together lower cover 52 and the chair back 2.
