DETAILED DESCRIPTION ​​

[0033] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the utility model.

[0034] With reference to Figure 1 - Figure 3 The utility model provides an embodiment: a refrigerant shunt filling device, including liquid storage tank 1, liquid storage tank 1 is used to store refrigerant, liquid storage tank 1 inside fixedly connected with shunt 2, the effect of shunt 2 is that the shunt filling of device can be realized, a plurality of filter assemblies are provided on one side of shunt 2, and the filter assembly is used to remove the impurities in the refrigerant.

[0035] The filter assembly includes a connecting barrel 5, which provides stable support and connection for the filter assembly. The connecting barrel 5 is fixedly connected to one side of the shunt 2. The filter barrel 3 is slidably connected inside the connecting barrel 5. The filter barrel 3 is used to filter the refrigerant and ensure that there is no impurity inside the refrigerant. A plurality of fitting blocks 4 are fixedly connected to one end of the filter barrel 3. A plurality of connecting blocks 6 are fixedly connected inside the connecting barrel 5. A clamping groove 7 is formed in the connecting block 6. The clamping groove 7 is matched with the fitting rod 10 to quickly lock and unlock the filter assembly. A sliding block 8 is slidably connected inside the connecting block 6. The sliding block 8 is fixedly connected to a clamping block 9 at one end. The fitting block 4 is matched with the clamping block 9. The fitting block 4 and the clamping block 9 can be quickly disassembled. The fitting rod 10 is rotatably connected inside the sliding block 8. The fitting rod 10 is matched with the clamping groove 7. A spring 11 is arranged at the bottom of the sliding block 8. The spring 11 provides elastic restoring force to quickly reset the assembly after movement. One end of the spring 11 is fixedly connected to the bottom end of the sliding block 8, and the other end is fixedly connected to the inner wall of the connecting block 6. A connecting assembly is arranged on the outer wall of the connecting barrel 5. The connecting assembly is used to conveniently connect the external pipeline by the user.

[0036] Specifically, when the refrigerant filling device needs to frequently replace the filter element, handle high-pollution refrigerant, or need rapid maintenance, first, through the flow divider 2, the effect of shunt filling can be achieved, so that the refrigerant can be accurately distributed to different pipelines, ensuring the efficiency and accuracy of the filling process, and the filter bucket 3 is responsible for quickly removing impurities inside the refrigerant, ensuring that the filled refrigerant is clean. When the filtering effect of the filter bucket 3 decreases and cannot effectively remove impurities, the operator can press the filter bucket 3, and the fitting block 4 drives the sliding block 8 to slide in the connecting block 6 through the action of the pressing force. This sliding further extrudes spring one 11, so that spring one 11 is elastically deformed, thereby providing the required force. While the sliding block 8 moves, the fitting block 4 drives the fitting rod 10 to slide in the clamping groove 7. When the fitting rod 10 slides to the specified position of the clamping groove 7, the lock in the clamping groove 7 will be unlocked, thereby realizing the rapid replacement or cleaning of the filter bucket 3, ensuring that the filling efficiency is not affected.

[0037] With reference to Figure 4 and Figure 5 , the connecting assembly includes a fixed ring one 12 and a fixed ring two 13, both of which are slidingly connected to the outer wall of the connecting bucket 5. The fixed ring one 12 and the fixed ring two 13 provide stable support and connection for the connecting assembly. The outer wall of the fixed ring one 12 is fixedly connected with upper and lower symmetrical fixed blocks two 15, and the outer wall of the fixed ring two 13 is fixedly connected with left and right symmetrical fixed blocks one 14. The fixed blocks two 15 and the fixed blocks one 14 also serve to provide support and connection, ensuring that the connecting assembly can be quickly connected. The inner walls of the fixed ring one 12 and the fixed ring two 13 are both fixedly connected with support frames 16, and one side of each support frame 16 is fixedly connected with a rubber ring 17. The rubber ring 17 serves to contact the external pipeline, thereby ensuring the sealing of the connecting assembly and preventing refrigerant leakage. The interiors of the fixed blocks one 14 and the fixed blocks two 15 are both slidingly connected with fixed shafts 18, and the interiors of the fixed shafts 18 are slidingly connected with transmission columns 19.

[0038] Specifically, when the refrigerant filling device needs to frequently replace equipment, temporarily expand the pipeline, or perform emergency maintenance, the operator first aligns the external pipeline with one end of the connecting bucket 5. Then, by pressing the fixed ring one 12 and the fixed ring two 13, the two fixed rings are tightly attached to the outer wall of the connecting bucket 5. During the pressing process, the fixed ring one 12 and the fixed ring two 13 cause the rubber ring 17 to tightly attach to the outer walls of the connecting bucket 5 and the external pipeline, thereby ensuring that the connection does not leak. Next, the operator presses the transmission column 19, causing spring two 20 to elastically deform. The deformation of spring two 20 allows the limiting rod 21 to rotate inside the fixed shaft 18, thereby retracting into the interior of the fixed shaft 18. This action allows the limiting rod 21 to be completely retracted into the fixed shaft 18, ensuring that the next installation proceeds smoothly.

[0039] With reference to Figure 4 And Figure 5 One end of the transmission column 19 is fixedly connected with the sliding rod 23, the outer wall of the sliding rod 23 is provided with the spring two 20, the spring two 20 provides elastic support for the assembly, and the spring two 20 provides certain elastic restoring force for the assembly, so that the stable movement of the assembly is ensured, one end of the spring two 20 is fixedly connected with the inner wall of the fixed shaft 18, the other end is fixedly connected with the side wall of the transmission column 19, the inside of the fixed shaft 18 is rotatably connected with the limiting rod 21, the limiting rod 21 is in contact with the fixed block two 15, so that the preliminary limiting effect is achieved, one end of the limiting rod 21 is in contact with the inner wall of the fixed shaft 18, the outer wall of the fixed shaft 18 is threadedly connected with the limiting disc 22, the limiting disc 22 is in contact with the fixed block one 14, so as to cooperate with the limiting rod 21 to realize stable locking.

[0040] Specifically, then, the operator inserts the fixed shaft 18 into the inside of the fixed block one 14 and the fixed block two 15, after completing the insertion, the pressing force on the transmission column 19 is released, the restoring force of the spring two 20 pushes the transmission column 19 to reset, when the transmission column 19 resets, the limiting rod 21 will automatically extend out and tightly fit with the side wall of the fixed block two 15 connected with the equipment, then the operator rotates the limiting disc 22 to make it rotate on the outer wall of the fixed shaft 18 and firmly contact with the side wall of the fixed block one 14, finally the quick locking is realized through the cooperation of the limiting rod 21 and the limiting disc 22, the stability and reliability of the connection are ensured, so that the convenience and safety of the whole filling operation are greatly improved.

[0041] Working principle: when using the refrigerant split filling device, the split filling effect can be realized through the flow divider 2, the internal impurities of the refrigerant can be quickly removed through the filter bucket 3, when the filtering effect of the filter bucket 3 is reduced and the impurities cannot be effectively removed, the filter bucket 3 is pressed by the operator, and under the action of the pressing force, the fitting block 4 drives the sliding block 8 to slide in the connecting block 6, the spring 11 is further extruded by the sliding of the sliding block 8, so that the spring 11 is elastically deformed, at the same time, the movement of the sliding block 8 also drives the fitting rod 10 to slide in the clamping groove 7, and when the fitting rod 10 slides to the specified position of the clamping groove 7, the unlocking function is realized, after unlocking, the operator can quickly replace or clean the filter bucket 3, so as to ensure the efficiency of filling, when the external pipeline needs to be connected during filling, first, the external pipeline is attached to one end of the connecting bucket 5, and then the fixed ring one 12 and the fixed ring two 13 are attached to the outer wall of the connecting bucket 5 by the operator, the fixed ring one 12 and the fixed ring two 13 are pressed, and under the action of the pressing force, the rubber ring 17 is tightly attached to the outer wall of the connecting bucket 5 and the external pipeline, then the transmission column 19 is pressed by the operator, and under the action of the pressing force, the spring 20 is elastically deformed, when the spring 20 is elastically deformed, the limiting rod 21 will rotate in the fixed shaft 18, so as to shrink into the fixed shaft 18, after the limiting rod 21 shrinks into the fixed shaft 18, the fixed shaft 18 is inserted into the fixed block one 14 and the fixed block two 15, after insertion, the pressing force of the transmission column 19 is released, the transmission column 19 is pushed back to the original position by the elastic restoring force of the spring 20, so that the limiting rod 21 extends and is attached to the side wall of the fixed block two 15, then the limiting disc 22 is rotated by the operator, so that the limiting disc 22 rotates on the outer wall of the fixed shaft 18 and is tightly attached to the side wall of the fixed block one 14, so that the quick locking is realized by the cooperation of the limiting rod 21 and the limiting disc 22, and the convenience of connection is ensured.
