Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1 to 10, a mounting structure for a medical grade pure water delivery system comprises a base plate 1 for mounting a lower distribution pipe a, a fixed ring unit 2 provided on the base plate 1 for supporting a purification tank b, a rotary ring unit 3 provided on the fixed ring unit 2 for snap-fixing the purification tank b, a top plate unit 4 provided on the rotary ring unit 3 for mounting an upper distribution pipe c, and an elastic ring unit 5 provided on the top plate unit 4 for pressing down the purification tank b and lifting up the rotary limiting ring unit 3.
In this embodiment, the purifying tank b is an ultrafiltration tank, a sterilization tank, or other tank types required for purifying the water body. The shape of the pure water purifying device is generally cylindrical, a plurality of the pure water purifying devices are arranged for use, and the pure water purifying device is matched with the upper distributing pipe c and the lower distributing pipe a, namely a complete purifying step in the medical pure water conveying system.
The upper distributing pipe c and the lower distributing pipe a are flat, the purifying tank b is simply and horizontally arranged, and the purifying tank b is required to be vertically installed, so that the purifying tank b is supported at the bottom by the fixed ring unit 2, clamped at the middle by the rotating ring unit 3 and tightly pressed at the upper part by the elastic ring unit 5, and the vertical installation state of the purifying tank b is relatively stable and is not easy to incline and fall.
Therefore, the fixed ring unit 2 needs to have a large structural strength, and the rotary ring unit 3 needs to have a large effective engagement range, so that the purification tank b having a small diameter can be applied and also can be engaged and then laterally fixed.
Then, the lower pressure of the elastic ring unit 5 should not be excessively large, which is mainly to assist in reinforcing the purification tank b. In other words, the pressing force of the elastic ring unit 5 also increases the load of the fixed ring unit 2, and the actual effective force of the elastic ring unit 5 is a static friction force due to the pressing force.
Finally, inside a medical purified water device, 1 booster pump e corresponds to the left and right 2 purification tanks b, and a plurality of purification tanks b can be connected in series in sequence, so that the medical pure water with superimposed purification effect and higher standard is finally obtained.
The fixing ring unit 2 includes an elevated column 201 provided on the base plate 1, a support plate 202 provided on the elevated column 201, and a plurality of fixing split rings 203 provided on the support plate 202 and used for supporting the purification tank b.
In this embodiment, the raised column 201 is configured to make a vertical space for installing the lower distributing pipe a, and the plane of the fixed split ring 203 is horizontally arranged, and the opening of the fixed split ring is the entry position of the tank pipe d below.
Furthermore, the fixed split rings 203 are positioned and number corresponding to the purification tank b, and an extension plate is further provided between the purification tank b and the support plate 202, so as to ensure that the purification tank b does not laterally squeeze the support plate 202 and the whole rotary ring unit 3.
Wherein, the material of solid fixed ring unit 2 is high strength steel, guarantees sufficient supporting strength.
The rotary ring unit 3 includes a lower support column 301 provided on the support plate 202, a cross plate 302 provided on the lower support column 301, a transverse opening 303 provided on the cross plate 302, a rotary shaft 304 inserted and provided on the transverse opening 303, and a rotary split ring 305 provided on the rotary shaft 304 and used for adjusting an effective clamping width by vertical rotation.
In this embodiment, the size of the rotary split ring 305 is larger than the fixed split ring 203, the former is used to engage the tank of the purification tank b, the latter allows the passage of the tank tube d, and the latter has an outer diameter smaller than the diameter of the tank of the purification tank b.
In addition, when the rotary split ring 305 is horizontal, the maximum effective clamping radius can be provided, and when the replaced purification tank b is relatively thin, the rotary split ring 305 can be used in a tilting manner after rotation, so that the thinner purification tank b can be clamped and can be transversely limited.
In other words, the finer the purification tank b, the more inclined the rotating split ring 305 is required, and the smaller the arcuate length of the effective engagement on the rotating split ring 305, but the engagement effect is still effective.
Thus, in this process, the rotating ring unit 3 is required to do the following 2 points:
1. the rotating shaft 304 can only rotate and can not be pulled out and plugged in;
2. the tilting of the rotating split ring 305 needs to be kept constant at all times.
Finally, it is acknowledged that the relatively flexible snap-in function of the rotary ring unit 3 is not applicable at all only for thinner purification tanks b if the purification tank b having a larger inner diameter than the rotary split ring 305 is replaced.
The rotary ring unit 3 further includes 2 stoppers 306 disposed on the rotary shaft 304 and respectively located at positions on both sides of the transverse plate 302.
In this embodiment, the 2 limiting blocks 306 are one of effective ways to implement only rotation and not plugging at the rotation shaft 304.
In other words, the stopper 306, the rotation shaft 304, the cross plate 302, and the rotation split ring 305 all require relatively large tensile and compressive strength. Because the medical grade pure water delivery system is likely to need to be moved and carried during use, the purification tank b has frequent shaking characteristics.
The top plate unit 4 includes an upper support column 401 provided on the cross plate 302, a top plate 402 provided on the upper support column 401, and a through hole 403 provided on the top plate 402 and used for passing through the tank tube d.
In this embodiment, the positions and the number of the perforations 403 are in one-to-one correspondence with the rotating split ring 305 and the fixed split ring 203.
The elastic ring unit 5 includes a fixing pipe 501 provided on the lower surface of the top plate 402, an insertion rod 502 provided on the fixing pipe 501, a lifting split ring 503 provided on the insertion rod 502 and used for pressing down the purification tank b, and a spring 504 provided in the fixing pipe 501 and used for lifting up the insertion rod 502 downward.
In this embodiment, the lifting split ring 503 is used in a similar manner to the fixed split ring 203, and also allows the tank tube d to be mounted sideways and to act on the end surface of the purification tank b.
Furthermore, the lifting split ring 503 is vertically aligned with the through hole 403, and the fixing pipe 501 is located at the side of the through hole 403, so that the elastic ring unit 5 avoids the upper tank pipe d.
Finally, the elastic ring unit 5 needs to generate a sufficient and suitable static friction force on the upper end surface of the purification tank b, by virtue of the spring 504. On the other hand, the lifting split ring 503 is made of rubber, which can provide a relatively large friction coefficient.
The elastic ring unit 5 further includes a tension string 505 provided on the fixed pipe 501 for pulling up the rotary split ring 305.
In this embodiment, the tension cord 505 is one of effective ways in which the inclined state of the rotary split ring 305 is fixedly maintained, and only one side of the rotary split ring 305, that is, the upper side of the rotary split ring 305, is provided with 1 tension cord 505.
On the other hand, the tension cord 505 may be an elastic cord or a non-elastic cord, and when it is a non-elastic cord, the mounting end of the tension cord on the fixing tube 501 may be further provided with a tension structure.
Finally, the tension cord 505 is not a force application portion for laterally engaging the purification tank b, and thus the strength thereof does not need to be excessively large.
In other words, when the rotary split ring 305 is inclined to engage with the smaller purification tank b, the rotary split ring 305 is also difficult to rotate downward again because the rotary split ring 305 itself is also suitably caught and rubbed against the purification tank b, and the tension string 505 can be understood as an auxiliary means.
The elastic ring unit 5 further includes a screw ring 506 provided on the outer circumferential surface of the fixed pipe 501 for mounting the tension string 505.
In this embodiment, the screw connection ring 506 can be matched with an inelastic tensioning rope 505, so that the inclined rotary split ring 305 is sufficiently tensioned and fixed, and the tensioning amplitude is flexibly adjustable.
The elastic ring unit 5 further comprises a vertical slot 507 provided on the fixed pipe 501, and a radial rod 508 provided on the insertion rod 502, passing through the vertical slot 507 and blocked and limited by the screw ring 506.
In this embodiment, the vertical slot 507 is formed upward from the lower surface of the fixed pipe 501, and may vertically penetrate the whole fixed pipe 501, or may be formed only by a partial depth.
In addition, the plugging relationship between the vertical slot 507 and the radial rod 508 is to ensure that the lifting split ring 503 can only lift and cannot rotate, and ensure that the opening positions of the fixed split ring 203, the rotating split ring 305 and the lifting split ring 503 are all on the same side.
On the other hand, the screw connection ring 506 can also limit and block the radial rod 508 at this time, so as to ensure that the lifting split ring 503 will not fall off and separate from the fixing tube 501 after the purification tank b to be replaced is removed.
The elastic ring unit 5 further includes an outer ring connection block 509 provided on the insertion rod 502 and the lifting split ring 503.
In this embodiment, a single lifting split ring 503 corresponds to 2 insertion rods 502 and 2 outer ring connecting blocks 509, so that 2 springs 504 can push the lifting split ring 503 smoothly and directly.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
