Description

Technical Field

[0001] The utility model relates to a liquid leakage protection box, a fluid connector component and a water distributor, and belongs to the technical field of connectors. Background Art

[0002] In the data center field, cold plate liquid cooling servers include two types: hand-plug architecture and blind-plug architecture. The single node of the liquid cooling server with blind-plug architecture is connected to the water distributor of the cabinet through a blind-plug fluid connector during the pushing process, automatically connecting liquid, power supply, data transmission, etc., without manual connection, and has the advantages of convenient connection and flexible layout.

[0003] For example, a Chinese invention patent application with application publication number CN111255967A discloses a liquid plug connector liquid plug assembly and a device interconnection system, wherein the liquid plug connector liquid plug assembly includes a pluggable first liquid plug connector and a second liquid plug connector, wherein the first liquid plug connector includes a first plug connector body, a fixing seat, a sealing sleeve and a sealing door, wherein in one embodiment, the sealing sleeve is a rigid structure, and the sealing sleeve is slidably connected to the first plug connector body along the plugging direction of the first plug connector body, and an opening is provided at the front end of the sealing sleeve, and the sealing sleeve can move between a first state and a second state relative to the fixing seat along the plugging direction of the plug connector body. When the sealing sleeve is in the first state, the sealing sleeve is sleeved on the front end of the first plug connector body, and when the sealing sleeve is in the second state, the front end of the first plug connector body is exposed from the opening to the outside of the sealing sleeve, and the sealing door is provided at the opening, and is used to open the opening before the front end of the first plug connector body is exposed from the opening to the outside of the sealing sleeve, and to close the opening after the sealing sleeve is sleeved on the outside of the front end of the first plug connector body.

[0004] The above technical solution arranges a sealing sleeve (i.e., a leakage protection box) and a sealing door (i.e., a protection door) on the outside of the first plug connector body, so that when the first liquid plug connector (i.e., the water distributor fluid connector, installed on the fixed seat on the water distributor side) and the second liquid plug connector (i.e., the server fluid connector, installed on the chassis) are not plugged in, the protection door is closed, and the protection door blocks the opening of the leakage protection box. If the valve core of the water distributor fluid connector fails and leakage occurs, the leaked liquid will flow into the space of the leakage protection box instead of flowing out of the entire water distributor fluid connector, thereby preventing the leaked liquid from damaging the electronic equipment on the server side.

[0005] At the same time, when the server fluid connector is plugged into the water distributor fluid connector, the server rear panel pushes the push rod that cooperates with the protection door transmission, thereby first controlling the protection door to open; when the push rod is fully retracted into the leakage protection box, the server rear panel pushes the entire leakage protection box to move backward, so that the plug-in end of the water distributor fluid connector is exposed from the leakage protection box for plugging with the server fluid connector. Among them, there is a certain plug-in matching length between the server fluid connector and the manifold fluid connector, which requires the leakage protection box to be able to move backward a sufficient distance to allow the plug-in end of the manifold fluid connector to be fully exposed, and the leakage protection box must be completely covered on the outside of the plug-in end of the manifold fluid connector before the two are plugged in, and it also has a certain length. As long as the rear panel of the server touches the leakage protection box, it will push it to move backward as a whole. For a leakage protection box of a certain size, when it is installed on different manifold fluid connectors, some leakage protection boxes are closer to the fixed seat of the manifold fluid connector, then the distance the leakage protection box moves backward will be limited, which can easily lead to the situation that the leakage protection box has already hit the fixed seat, but the server fluid connector and the manifold fluid connector have not yet completed the plug-in, resulting in a plug-in failure. Utility Model Content

[0006] The purpose of the present utility model is to provide a liquid leakage protection box to solve the problem in the prior art that when the rear panel of the server contacts the liquid leakage protection box, it will push the entire server to move backward, and when the distance between the liquid leakage protection box and the fixing seat of the manifold fluid connector is insufficient, it is easy to cause the liquid leakage protection box to contact the fixing seat, but the server fluid connector and the manifold fluid connector have not yet been plugged in, resulting in a plugging failure; the purpose of the present utility model is also to provide a fluid connector assembly and a manifold to solve the above problems.

[0007] In order to achieve the above purpose, the leakage protection box in the utility model adopts the following technical solutions:

[0008] The leakage protection box comprises a first box body and a second box body which are sleeved and slidably matched with each other, the first box body is used to be arranged outside the plug-in end of the water distributor fluid connector, and the front side wall of the first box body is provided with a through hole for the plug-in end to pass through; the second box body is used to be arranged outside the part on the rear side of the plug-in end, and the front end of the second box body and the rear end of the first box body are provided with a stop structure which stops and cooperates in the forward direction, and the first box body and the second box body are respectively provided with through holes for the guide column installed on the fixed seat of the water distributor fluid connector to pass through, the leakage protection box also comprises a first spring which is sleeved on the guide column and has one end abutting against the front side wall or the rear side wall of the first box body and the other end abutting against the step of the guide column or the fixed seat, and the leakage protection box also comprises an anti-slip structure for preventing the second box body from escaping from the water distributor fluid connector.

[0009] The beneficial effect of the above technical solution is that: the utility model proposes a pioneering liquid leakage protection box, which includes two box bodies that are mutually sleeved and slidably matched, wherein the first box body is used to be arranged outside the plug-in end of the water distributor fluid connector to collect liquid when leaking; the front side wall of the first box body is provided with a through hole for the plug-in end to pass through, ensuring that the water distributor fluid connector can be normally plugged with the server fluid connector. The second box body is used to be arranged outside the part behind the plug-in end, and the front end of the second box body and the rear end of the first box body are provided with a stop structure that stops in the forward direction, and the first box body can be prevented from separating from the second box body forward by the stop structure; the first box body and the second box body are respectively provided with through holes for the guide column installed on the fixed seat of the water distributor fluid connector to pass through, retaining the guiding function of the guide column, and can guide the water distributor fluid connector and the server fluid connector when they are plugged. The liquid leakage protection box also includes a first spring which is sleeved on the guide column and has one end abutting against the front side wall or the rear side wall of the first box body and the other end abutting against the step or the fixed seat of the guide column. The first spring can apply a forward force to the first box body so that the first box body is in a state where the rear end is blocked by the second box body; the liquid leakage protection box also includes an anti-detachment structure for preventing the second box body from detaching from the water distributor fluid connector, thereby ensuring that the first box body will not detach from the water distributor fluid connector.

[0010] In summary, when the leakage protection box of the utility model is in use, when the water distributor fluid connector is not plugged into the server fluid connector, the first box body is located at the extreme front position under the action of the first spring, and the second box body is kept at the extreme front position by the stop structure. During the plugging process of the water distributor fluid connector and the server fluid connector, the server rear panel first contacts the first box body and pushes the first box body to move backward. Since the first box body and the second box body are mutually sleeved and slidably matched, the second box body does not move. Only when the first box body moves backward, the first box body pushes the second box body to move backward together when it reaches a certain degree. Compared with the prior art, when the first box body is in the extreme forward position, that is, the first box body and the second box body are in the extended state, the total front-to-back width of the two box bodies in the extended state is set to be equal to the front-to-back width of a single box body in the prior art. Then, the leakage protection box of the utility model does not move backward as a whole when the server rear panel is pushed, but is divided into two stages. In the front, only the first box body moves backward, so that the plug-in end of the water distributor fluid connector has moved forward a certain distance relative to the first box body, and then the second box body moves backward. The second box body does not need to move backward a lot to ensure that the water distributor fluid connector and the server fluid connector are plugged in. Therefore, it can avoid the situation that the leakage protection box has already hit the fixed seat, but the server fluid connector and the water distributor fluid connector have not yet completed the plug-in, and ensure the successful plug-in. Among them, the first spring is deformed by force during the backward movement of the two boxes, and the two boxes can be reset when the water distributor fluid connector and the server fluid connector are disconnected, so as to be reused.

[0011] Furthermore, the leakage protection box also includes a limiting member with one end fixed on the fixing seat and the other end located in the second box body and cooperating with the rear side wall of the second box body in a forward blocking direction, and the limiting member constitutes the anti-slip structure.

[0012] Furthermore, the limiting member is a limiting screw for threadedly cooperating with the fixing seat, and the head of the limiting screw is located in the second box body and is stop-cooperating with the rear side wall of the second box body in the forward direction.

[0017] Furthermore, a protective door is installed in the first box body for covering the port of the plug-in end and can be opened to make way for the port. When the protective door is in the open state, it is close to the left side wall or the right side wall of the first box body and makes way for the second box body, so that when the first box body moves backward to a certain extent, the front side wall of the first box body pushes the second box body to move backward synchronously.

[0018] Furthermore, the first box body is sleeved on the outside of the second box body, and the second box body includes a sleeve for being sleeved on the outside of the two water distributor fluid connectors, the two sleeves are arranged on the left and right, and the second box body also includes a bottom wall connected between the tops of the two sleeves and the bottoms, and the space between the two sleeves and the top wall and the bottom wall constitutes a through structure on the second box body.

[0019] In order to achieve the above-mentioned purpose, the fluid connector assembly in the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0055] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0056] In view of the technical problems existing in the prior art, the basic technical concept of the utility model is to set the liquid leakage protection box as two box bodies. Through the mutual arrangement and sliding cooperation of the two box bodies, the server rear panel first contacts the first box body and pushes the first box body to move backward, while the second box body does not move temporarily. Only when the first box body moves backward to a certain extent will it push the second box body to move backward together. In the process of the first box body moving backward alone, the plug-in end of the water divider fluid connector can move forward a certain distance relative to the first box body. Therefore, when the second box body moves, it does not need to move backward a lot to ensure that the water divider fluid connector and the server fluid connector are plugged in, thereby ensuring successful plug-in.

At the same time, two left and right manifold fluid connectors 3 are installed on one fixing seat 2, the two guide posts 4 are located between the two manifold fluid connectors 3, and a plurality of fixing seats 2 are fixed on the manifold body 1 in the up and down directions, and each fixing seat 2 has the same structure arrangement.

[0059] Specifically, if Figure 1 and Figure 2 As shown, the leakage protection box in the present invention comprises a first box body 5 and a second box body 6 which are sleeved and slidably matched with each other. The first box body 5 is used to be arranged outside the plug-in end of the manifold fluid connector 3 to collect liquid when the manifold fluid connector 3 leaks. Figure 4 and Figure 5 As shown, the first box body 5 includes a first top wall 5-1, a first bottom wall 5-2, a first front side wall 5-3, a first rear side wall 5-4, a first left side wall 5-5 and a first right side wall 5-6. The first front side wall 5-3 is provided with a through hole 5-7 for the plug-in end of the manifold fluid connector 3 to pass through, so that the plug-in end can be normally plugged with the above-mentioned server fluid connector 10. Since there are two manifold fluid connectors 3, there are also two through holes 5-7, which are arranged on the left and right.

[0060] In addition, if Figure 4 and Figure 5As shown, the first front side wall 5-3 is also provided with a first through hole 5-8 for the guide column 4 to pass through, so as to ensure that the guide column 4 can achieve the guiding function. Since the guide column 4 is provided with two upper and lower ones, the first through holes 5-8 are also provided with two and arranged in an upper and lower manner. The first box body 5 also includes a liquid outlet pipe 5-10 for discharging the liquid collected in the box body. Figure 1 As shown, the water distributor also includes a vertically arranged drainage pipe 7, on which a plurality of liquid receiving grooves 7-1 are arranged at intervals in the up and down directions. The liquid outlet pipe 5-10 of each first box body 5 is located above the corresponding liquid receiving groove 7-1, and the discharged liquid first flows into the drainage pipe 7 through the liquid receiving groove 7-1 and then is discharged uniformly.

[0061] like Figure 2 and Figure 8 As shown, the first box body 5 is installed with a protective door 5-12 for shielding the plug-in end of the water distributor fluid connector 3 and can be opened to open the port, combined with Fig. 9 As shown, the protective door 5-12 includes a door panel 5-12-1 and a rotating shaft 5-12-3 arranged at the upper and lower ends of the door panel 5-12-1. The protective door 5-12 is rotatably mounted on the first top wall 5-1 and the first bottom wall 5-2 of the first box body 5 through the upper and lower rotating shafts 5-12-3. At the same time, a connecting rod 5-12-2 is arranged at the upper end of the door panel 5-12-1. The connecting rod 5-12-2 and the door panel 5-12-1 are relatively fixed. The specific fixing method can be integrally connected or welded. The upper rotating shaft 5-12-3 is located on the connecting rod 5-12-2. The connecting rod 5-12-2 is also provided with a pin 5-12-4. The pin 5-12-4 is offset on one side of the line connecting the upper and lower rotating shafts 5-12-3. The first box body 5 also includes a push rod 5-13 hingedly connected to the protective door 5-12 through a pin shaft 5-12-4. Specifically, a long hole is provided at the end of the push rod 5-13, and the pin shaft 5-12-4 is located in the long hole. Figure 4 As shown, a protruding hole 5-11 is provided on the first front side wall 5-3 for the push rod 5-13 to protrude from the first box body 5, as shown in FIG. Figure 2 As shown, the extended end of the push rod 5-13 is used to push and cooperate with the server rear panel 9. Figure 8 As shown, a torsion spring 5-14 is sleeved on the outer portion of the lower end of the door panel 5-12-1, and bosses 5-15 are respectively provided on the door panel 5-12-1 and the first bottom wall 5-2, and both ends of the torsion spring 5-14 are respectively clamped on the bosses 5-15.

[0062] The opening process of the protective door 5-12 is as follows: Fig.11 As shown, a crank-connecting rod mechanism is formed between the protective door 5-12 and the push rod 5-13. Fig.11(a) shows that the protective door panel 5-12-1 is in a closed state (i.e., the door panel 5-12-1 blocks the port of the plug-in end of the water distributor fluid connector 3). When the server chassis is pushed into the cabinet, the push rod 5-13 contacts the server rear panel 9 and moves backward in a straight line, and then the push rod 5-13 pushes the protective door 5-12 to rotate. Fig.11 (b) ~ Fig.11 (g) is the process of door panel 5-12-1 gradually opening. Fig.11 (h) The door panel 5-12-1 is in a fully open state (i.e., the door panel 5-12-1 leaves the port open). When the door panel 5-12-1 changes from a closed state to a fully open state, the torsion spring 5-14 is compressed and deformed, so when the server chassis is pulled out, the door panel 5-12-1 can be driven to return from a fully open state to a closed state, and the process is just the opposite.

[0063] like Figure 2 , Figure 8 and Fig. 9 As shown, since there are two water distributor fluid connectors 3, there are also two corresponding protective doors 5-12, and since the connecting rod 5-12-2 and the door panel 5-12-1 are arranged at a certain angle, the push rod 5-13 on the left side pushes the protective door 5-12 on the left side to rotate toward the direction close to the first left side wall 5-5, and the push rod 5-13 on the right side pushes the protective door 5-12 on the right side to rotate toward the direction close to the first right side wall 5-6. When the protective door 5-12 on the left side is in the open state, it is close to the first left side wall 5-5, and when the protective door 5-12 on the right side is in the open state, it is close to the first right side wall 5-6.

[0064] In addition, since the installation position of the rotating shaft 5-12-3 of the protective door 5-12 and the first top wall 5-1 and the first bottom wall 5-2 is closer to the first rear side wall 5-4, the push rod 5-13 needs to pass through the first rear side wall 5-4 during the backward movement. Figure 5 As shown, an avoidance hole 5-16 for avoiding the push rod 5-13 is provided on the first rear side wall 5-4.

[0065] like Figure 1 and Figure 2 As shown, the second box body 6 is used to be arranged outside the rear side of the plug-in end of the water distributor fluid connector 3, and the front end of the second box body 6 extends into the first box body 5, that is, the first box body 5 is sleeved outside the second box body 6, as shown in FIG. Figure 5As shown, a relatively large opening is provided on the first rear side wall 5-4, which is adapted to the shape of the second box body 6 so that the front end of the second box body 6 can be inserted. Of course, the opening is also provided for the two guide posts 4 mentioned above to pass through. The front end of the second box body 6 and the rear end of the first box body 5 are provided with a stop structure that stops in the forward direction, and the stop structure can prevent the first box body 5 from separating from the second box body 6 forward. Figure 6 As shown, the stopping structure includes a flange 6-5 which is arranged at the front end of the second box body 6 and protrudes outward, and the first rear side wall 5-4 of the first box body 5 is matched with the flange 6-5 in a forward direction.

[0066] Combination Figure 6 and Figure 7 As shown, the second box body 6 includes a sleeve 6-1 for sleeved on the outside of the two water distributor fluid connectors 3, the two sleeves 6-1 are arranged left and right, the second box body 6 also includes a second top wall 6-2 connected between the tops of the two sleeves 6-1 and a second bottom wall 6-3 between the bottoms, the two sleeves 6-1 and the space between the top wall 6-2 and the bottom wall 6-3 constitute a through structure on the second box body 6, and the through structure can allow the above-mentioned two guide columns 4 to pass through. The second box body 6 also includes a second rear side wall 6-4, and the second rear side wall 6-4 is provided with a second through hole 6-6 for the above-mentioned guide column 4 to pass through, and correspondingly, two second through holes 6-6 are provided and arranged up and down.

[0067] like Figure 2 As shown, the liquid leakage protection box also includes a first spring 11 which is respectively sleeved on the upper and lower guide pillars 4 and one end of which is pressed against the first front side wall 5-3 of the first box body 5 and the other end of which is pressed against the step of the guide pillar 4. The first spring 11 can apply a forward force to the first box body 5 so that the first box body 5 is in a state where the rear end is blocked by the second box body 6. It should be noted that since the first spring 11 also passes through the second through hole 6-6, the second through hole 6-6 is required to be large enough to avoid the first spring 11 from being stuck when the second box body 6 slides forward and backward relative to the guide pillar 4.

[0068] The leakage protection box also includes an anti-slip structure for preventing the second box body 6 from slipping out of the water distributor fluid connector 3. The anti-slip structure is specifically a stopper with one end fixed on the fixing seat 2 and the other end located in the second box body 6 and cooperating with the second rear side wall 6-4 of the second box body 6 in the forward direction. The stopper can prevent the second box body 6 from slipping out of the water distributor fluid connector 3, thereby ensuring that the first box body 5 will not slip out of the water distributor fluid connector 3. Specifically, Figure 3As shown, the limiting member is a limiting screw 8 threadedly connected to the fixing seat 2, and the head of the limiting screw 8 is located in the second box body 6 and is blocked and matched with the second rear side wall 6-4 in the forward direction. The use of the limiting screw 8 as the limiting member is convenient for installation and disassembly, and at the same time, the position of the limiting screw 8 screwed into the fixing seat 2 can be adjusted, and the distance between the second box body 6 and the fixing seat 2 can be adjusted, thereby adjusting the distance between the first box body 5 and the fixing seat 2 and the covering position of the first box body 5 for the plug-in end of the water distributor fluid connector 3, so as to obtain better protection and plug-in effects.

[0069] Furthermore, in order to facilitate the installation and adjustment of the limit screw 8, as Figure 4 As shown, an operation hole 5-9 for the installation tool to insert to install the limit screw 8 is provided on the first front side wall 5-3 of the first box body 5. At this time, the large opening on the first rear side wall 5-4 constitutes a through structure for the installation tool to pass through, and the through structure on the second box body 6 is also for the installation tool to pass through for operation. And in this embodiment, the limit screw 8 is located between the upper and lower guide columns 4, which does not take up extra space and ensures that the force applied by the limit screw 8 to the second box body 6 is located at the center of the second box body 6. Correspondingly, the operation hole 5-9 is located between the upper and lower first through holes 5-8, and as shown in FIG. Figure 7 As shown, a screw through hole 6-7 for the limit screw 8 to pass through is provided between the upper and lower second through holes 6-6 on the second rear side wall 6-4.

[0070] In addition, when selecting the limit screw 8, a screw with a majority of the rod being an optical axis section can be selected. In this case, a second spring can be sleeved on the outside of the limit screw 8, with one end of the second spring abutting against the second rear side wall 6-4 and the other end abutting against the fixing seat 2.

[0071] The working process of the fluid connector assembly in the utility model is as follows: Figure 1 and Fig.10 As shown, the details are as follows:

[0072] like Fig.10 As shown in (a), when the server chassis is not pushed in (i.e., the manifold fluid connector 3 is not plugged into the server fluid connector 10), the first box body 5 is located at the front limit position under the action of the first spring 11, and the second box body 6 is maintained at the front limit position by the blocking structure. At this time, the first box body 5 is covered on the outside of the plug-in end of the manifold fluid connector 3, and the protective door 5-12 is in a closed state, covering the port of the plug-in end of the manifold fluid connector 3. At this time, if there is liquid leakage, the liquid splashes onto the protective door 5-12 and flows to the bottom of the first box body 5, and then is discharged into the liquid receiving tank 7-1 through the liquid outlet pipe 5-10, and then enters the liquid discharge pipe 7, so as to avoid splashing onto the electronic equipment on the server side and causing damage to the equipment.

[0073] When pushing into the server chassis, Fig.10 As shown in (b), the server rear panel 9 contacts the push rod 5-13, pushing the push rod 5-13 to make a linear motion backward along the plug-in direction of the water distributor fluid connector 3. Under the action of the crank-connecting rod mechanism, the push rod 5-13 pushes the protective door 5-12 to rotate. As the server chassis is pushed in further, the protective door 5-12 is fully opened before the plug-in surface of the water distributor fluid connector 3 and the server fluid connector 10 contacts. The protective door 5-12 rotates to the side of the plug-in end of the water distributor fluid connector 3, completely exposing the port of the plug-in end. At this time, the push rod 5-13 is fully retracted, and the server rear panel 9 contacts the front side wall of the first box body 5, as shown in FIG. Fig.10 (c) shown.

[0074] After that, as the server chassis continues to be pushed in, the server rear panel 9 will push the first box body 5 to move backwards. Since the first box body 5 and the second box body 6 are mutually sleeved and slidably matched, and the second spring acts, the second box body 6 does not move, and only the first box body 5 moves backwards. Since the protective doors 5-12 on both sides are rotated to the side, this not only clears the water distributor fluid connector 3, but also clears the second box body 6, so that the first box body 5 can move backwards relative to the second box body 6 until the front side wall of the first box body 5 contacts the front side wall of the second box body 6, as shown in FIG. Fig.10 (d) As shown. Thereafter, the first box body 5 pushes the second box body 6 to move backward together until the water distributor fluid connector 3 and the server fluid connector 10 are plugged in. Fig.10 (e) shown.

[0075] The leakage protection box of the utility model includes two box bodies. Compared with the prior art, when the first box body 5 is in the front limit position, that is, the first box body 5 and the second box body 6 are in the extended state, the total front-to-back width of the two box bodies in the extended state is set to be equal to the front-to-back width of a single box body in the prior art. Then, the leakage protection box of the utility model does not move backward as a whole when the server rear panel 9 is pushed, but is divided into two stages. In the front, only the first box body 5 moves backward, so that the plug-in end of the water divider fluid connector 3 has moved forward a certain distance relative to the first box body 5, and then the second box body 6 moves backward. The second box body 6 does not need to move backward a lot to ensure that the water divider fluid connector 3 and the server fluid connector 10 are plugged in. Therefore, it can avoid the situation that the leakage protection box has already hit the fixing seat 2, but the server fluid connector 3 and the water divider fluid connector 10 have not yet completed the plug-in, thereby ensuring successful plug-in. The first spring 11 is deformed by force during the backward movement of the two boxes, and the second spring is deformed by force during the backward movement of the second box 6, so that the two boxes can be reset when the manifold fluid connector 3 is disconnected from the server fluid connector 10. At the same time, when the two connectors are disconnected, the protective door 5-12 in the first box 5 can be reset under the action of the torsion spring to restore to the state of shielding the plug-in port of the manifold fluid connector 3 for repeated use.

[0076] It should also be noted that the present invention sets the leakage protection box as two box bodies. Compared with directly reducing the front and rear width of a single box body in the prior art, although the front and rear width of the single box body is reduced, the distance from the rear side wall of the single box body to the fixing seat can be increased, thereby increasing the spatial distance that the single box body can move backward, avoiding the situation that the box body has already hit the fixing seat while the server fluid connector and the water distributor fluid connector have not yet completed the plug-in, but this will cause the length of the limit screw to be relatively long, and then in the process of the box body being pushed backward, the head of the limit screw will extend out of the box body, so it is necessary to set a corresponding avoidance structure on the server rear panel or even inside the server, which leads to a high cost of transformation. The double-layer box body seems to have a complex structure, but it cleverly avoids this problem. The head of the limit screw is matched with the rear side wall of the second box body. Compared with the limit screw set on the single box body, the length does not change, and the head of the limit screw will not extend out of the first box body. Therefore, there is no need to change the structure on the server side, and it is only necessary to install the leakage protection box with a double box body structure on the water distributor fluid connector.

[0077] In other embodiments of the water divider: for the structure of the second box body, a second front side wall may be provided between the two sleeves, in which case a through hole for the guide column and the first spring on the guide column to pass through needs to be provided on the second front side wall, and a through hole for the installation tool to pass through also needs to be provided on the second front side wall, and the through hole at this time constitutes a through structure on the second box body. Of course, in other embodiments, the second box body may not have two sleeve structures, but the left and right sides of the second box body may be provided as arc-shaped walls to match the outer peripheral surface of the fluid connector of the water divider, and the interior of the second box body is a hollow structure as a whole.

[0078] In other embodiments of the water divider: the second box body may not be moved backward by being pushed by the front side wall of the first box body, but a pushing structure is provided on the top wall or the bottom wall of the first box body, and when the first box body moves backward to a certain extent, the pushing structure is blocked by the front side wall of the second box body, thereby pushing the second box body to move backward.

[0079] In other embodiments of the water divider: the rear end of the first box body can be extended into the second box body, that is, the second box body is sleeved outside the first box body. In this case, a flange needs to be provided at the rear end of the first box body, and the flange is used to stop and cooperate with the front side wall of the second box body in the forward direction. In other embodiments, regardless of how the first box body and the second box body are sleeved, flanges can be provided at the front end of the second box body and the rear end of the first box body, and the flanges are used to stop and cooperate, and the side wall of a box body is no longer used for stopping.

[0080] In other embodiments of the water divider: when a second spring is sleeved on the limit screw, the other end of the second spring can also be against the step of the limit screw itself; of course, in other embodiments, the second spring may not be provided, and only the sliding fit between the first box body and the second box body is utilized to keep the second box body stationary when the first box body moves.

[0081] In other embodiments of the water divider: when there are two guide columns, the limit screw can also be set outside the area between the two guide columns, and the number of limit screws is not limited to one. For example, a limit screw can be set above the upper guide column, and another limit screw can be set below the lower guide column. In this case, the position of the screw hole will also change accordingly. In other embodiments, only one guide column can be set, for example, the guide column is an outer hexagonal column or a square column, and the limit screw can also be flexibly set.

[0082] In other embodiments of the water divider: when the first box body extends into the second box body, and the first box body has a rear side wall, a through structure, such as a through hole, for the installation tool to pass through needs to be provided on the rear side wall of the first box body. In other embodiments, an operation hole can be provided on the top wall or the bottom wall of the second box body, and the limit screw is installed through the operation hole, and is also adjusted through the operation hole. In this case, there is no need to provide an operation hole on the front side wall of the first box body. In other embodiments, the top wall or the bottom wall of the second box body can be set to be installed and fixed last. Before the top wall or the bottom wall is installed and fixed, the limit screw can be installed by using the formed opening. After installation, the top wall or the bottom wall is fixed. In this case, the limit screw is no longer adjusted during use.

[0083] In other embodiments of the water divider: the limit member may not be a limit screw, for example, a smooth limit rod, the rear end of the limit rod is directly welded or adhesively fixed to the fixing seat, the front end of the limit rod is integrally formed with a stop head, the stop head is located in the second box body and cooperates with the rear side wall of the second box body, or the limit rod is a column of equal diameter, and one end of the limit rod located in the second box body is equipped with a cotter pin or a retaining ring to cooperate with the rear side wall of the second box body.

[0084] In other embodiments of the water divider: the anti-slip structure can also be an anti-slip piece with one end fixed on the fixing seat and the other end extending into the second box body and cooperating with the protrusion on the top wall or bottom wall of the second box body in the forward direction, for example, a hook is provided at the front end of the anti-slip piece, and the hook is hooked with the protrusion to prevent the second box body from slipping out of the water divider fluid connector forward. In other embodiments, a flange extending inward is provided at the rear port of the through hole on the second box body for the water divider fluid connector to pass through, and a step is provided on the periphery of the water divider fluid connector to cooperate with the flange in the forward direction, and in this case, the flange constitutes the anti-slip structure.

[0085] In other embodiments of the water divider: when the first box body extends into the second box body and the first box body has a rear side wall, one end of the first spring can also abut against the rear side wall of the first box body; in other embodiments, the other end of the first spring can also directly abut against the fixing seat.

[0086] The embodiment of the fluid connector assembly in the present utility model is as follows: the specific structure of the fluid connector assembly is the same as the fluid connector assembly in the above-mentioned water distributor embodiment, and will not be repeated here.

[0087] The embodiment of the liquid leakage protection box in the present utility model is as follows: The specific structure of the liquid leakage protection box is the same as the liquid leakage protection box in the above-mentioned water distributor embodiment, and will not be repeated here.
