Description

Technical Field

[0001] This utility model relates to the field of cooling pump technology, and in particular to a cooling pump that is easy to assemble and disassemble. Background Technology

[0002] The lack of protective structures in commercially available cooling pumps poses certain safety risks during actual use. Furthermore, the inability to replace the impeller results in a relatively short overall lifespan for the cooling pump.

[0003] To address the aforementioned issues, a cooling pump is disclosed in patent document CN212250487U, comprising a base and a protective mechanism. A motor is mounted on one side of the upper end of the base, and a motor shaft is connected to the center of one end of the motor. A shaft fixing cylinder is fixed to the outside of the motor shaft, and a connecting mechanism is connected to the other end of the motor shaft.

[0004] Based on the above search and combined with existing technology, it was found that existing cooling pumps are mostly connected and fixed to external pipes by multiple bolts through connecting rings. However, during installation, it is necessary to align the connecting rings of the external pipes with the connecting rings of the cooling pump, and to align the through holes before the bolts can be inserted and connected. Manual alignment is difficult and the connection is inconvenient. Therefore, a cooling pump that is easy to disassemble and assemble is needed. Utility Model Content

[0005] The purpose of this application is to provide a cooling pump that is easy to install and disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a cooling pump that is easy to assemble and disassemble, comprising a cooling pump body, wherein a plurality of connecting pipes are provided on the cooling pump body, and a connecting ring is fixed to the end of each of the plurality of connecting pipes;

[0007] The surface of the connecting ring away from the connecting tube has multiple perforations distributed circumferentially along the axis of the connecting ring;

[0008] A positioning element is installed on the surface of the connecting ring away from the connecting pipe. The positioning element is elastically connected to the connecting ring through an elastic element. The inner diameter of the positioning element is the same as the diameter of the through hole. The positioning element is used to limit the external pipe when it is inserted into the hole when the through hole corresponds to the hole of the external pipe connecting ring.

[0009] A guide bucket is also fixed around the connecting ring. The guide bucket is used to guide the external pipe connecting ring to make it coaxial with the connecting ring.

[0010] As a further supplement to this solution, the surface of the connecting ring is also provided with a movable groove that communicates with the through hole, and the inner diameter of the movable groove is larger than the inner diameter of the through hole.

[0011] The positioning component includes a positioning short tube, which is slidably connected in the movable groove. The inner diameter of the positioning short tube is the same as the inner diameter of the perforation, and the outer diameter of the positioning short tube is the same as the inner diameter of the movable groove.

[0012] As a further supplement to this solution, a mounting hole communicating with the through hole is provided inside the connecting ring. The inner diameter of the mounting hole is larger than the inner diameter of the through hole and the movable groove, and the mounting hole is located between the through hole and the mounting hole.

[0013] The elastic element includes a first spring, which is located inside the mounting hole. One end of the first spring is fixed to the bottom wall of the mounting hole, and the other end of the first spring is fixed to the tail end of the positioning short tube.

[0014] As a further supplement to this solution, one end of the positioning short tube extends to the outside of the connecting ring and forms a chamfered part, and the other end of the positioning short tube extends into the mounting hole and is integrally formed with a limiting ring. The inner diameter of the limiting ring is consistent with the inner diameter of the positioning short tube, and the outer diameter of the limiting ring is consistent with the inner diameter of the mounting hole.

[0015] The other end of the first spring is fixed to the limiting ring.

[0016] As a further supplement to this solution, a mating hole is formed in the middle of the guide bucket, which is consistent with the outer diameter of the connecting ring and the outer diameter of the external pipe connecting ring;

[0017] An installation groove is provided at the top of the mating hole. An abutment block is slidably connected in the installation groove. The tail end of the abutment block forms a limiting baffle. The diameter of the limiting baffle is the same as the inner diameter of the installation groove. One side of the limiting baffle is elastically connected to the inner sidewall of the installation groove through a second spring.

[0018] As a further supplement to this solution, multiple positioning short tubes and abutment blocks are provided. Each positioning short tube corresponds to a different perforation, and multiple abutment blocks are staggered between the multiple positioning short tubes.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] 1. In this utility model, by setting up a positioning short tube and a first spring, when connecting the external pipe to the connecting pipe, the worker only needs to hold the external pipe and place the external pipe connector in the guide bucket, and then move it to one side of the connecting pipe. Under the guidance of the guide bucket, the external pipe connecting ring will automatically align with the connecting ring coaxially. Then, by rotating the external pipe, the hole on the external pipe connecting ring will correspond to the through hole position during the rotation. At this time, the positioning short tube will pop out under the elastic force of the first spring and insert into the hole of the external pipe connecting ring, limiting the movement of the external pipe connecting ring and thus stopping the movement of the external pipe connecting ring and completing the alignment. After that, the worker only needs to pass the bolt through the hole and through hole of the external pipe connecting ring to fix the external pipe to the connecting pipe. This saves the worker time in finding the correct position when connecting the external pipe, thereby improving the connection efficiency and facilitating the installation of the cooling pump. When disassembling, only the bolt needs to be removed, and disassembly is also convenient.

[0021] 2. In this utility model, by setting the abutment block and the second spring, when the external pipe connecting ring abuts against the connecting ring, the abutment block extends under the elastic force of the second spring and abuts against the back side of the external pipe connecting ring away from the connecting ring. This, together with the positioning short pipe, tightens and limits the external pipe connecting ring, ensuring that it no longer rotates and preventing it from falling off. This makes it convenient for workers to temporarily loosen the external pipe for bolt installation and connection, which is conducive to quick installation by a single person and is more convenient to use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Reference Figures 1-4 The cooling pump shown is easy to assemble and disassemble, including a cooling pump body 1, a plurality of connecting pipes 11 are provided on the cooling pump body 1, and a connecting ring 2 is fixed to the end of each of the plurality of connecting pipes 11.

[0030] Multiple through holes 21 are provided on the surface of the connecting ring 2 away from the connecting tube 11, which are distributed circumferentially along the axis of the connecting ring 2.

[0031] A positioning element is installed on the surface of the connecting ring 2 away from the connecting pipe 11. The positioning element is elastically connected to the connecting ring 2 through an elastic element. The inner diameter of the positioning element is the same as the diameter of the through hole 21. The positioning element is used to limit the external pipe when it is inserted into the hole when the through hole 21 corresponds to the hole of the external pipe connecting ring.

[0032] A guide bucket 3 is also fixed around the connecting ring 2. The guide bucket 3 is used to guide the external pipe connecting ring so that it is coaxial with the connecting ring 2.

[0033] Based on the above structure, when connecting the external pipe to the connecting pipe 11, the operator only needs to hold the external pipe and place the external pipe connector in the guide bucket 3, and then move it to the side of the connecting pipe 11. Under the guidance of the guide bucket 3, the external pipe connecting ring will automatically align with the connecting ring 2 on the same axis. Then, by rotating the external pipe, the hole on the external pipe connecting ring will correspond to the position of the through hole 21 during the rotation. At this time, the positioning piece will pop out under the elastic force of the elastic element and insert into the hole of the external pipe connecting ring, limiting the external pipe connecting ring. This will stop the external pipe connecting ring from moving and complete the alignment. After that, the operator only needs to insert the bolt through the hole of the external pipe connecting ring and the through hole 21 to fix the external pipe to the connecting pipe 11. This saves the operator time in finding the correct position when connecting the external pipe, thereby improving the connection efficiency and facilitating the installation of the cooling pump. When disassembling, only the bolt needs to be removed, making disassembly equally convenient.

[0034] It should be noted that the inner diameter of the hole of the external pipe connecting ring needs to be consistent with the outer diameter of the elastic element, or the hole of the external pipe connecting ring can be set as a stepped hole, with the inner diameter of the small hole consistent with the inner diameter of the through hole 21, and the inner diameter of the large hole consistent with the outer diameter of the elastic element.

[0035] Furthermore, the surface of the connecting ring 2 is also provided with a movable groove 23 that communicates with the through hole 21, and the inner diameter of the movable groove 23 is larger than the inner diameter of the through hole 21.

[0036] The positioning component includes a positioning short tube 4, which is slidably connected in the movable groove 23. The inner diameter of the positioning short tube 4 is the same as the inner diameter of the through hole 21, and the outer diameter of the positioning short tube 4 is the same as the inner diameter of the movable groove 23.

[0037] The connecting ring 2 has a mounting hole 22 that communicates with the through hole 21. The inner diameter of the mounting hole 22 is larger than the inner diameter of the through hole 21 and the movable groove 23. The mounting hole 22 is located between the through hole 21 and the mounting hole 22.

[0038] The elastic element includes a first spring 5, which is located inside the mounting hole 22. One end of the first spring 5 is fixed to the bottom wall inside the mounting hole 22, and the other end of the first spring 5 is fixed to the tail end of the positioning short tube 4.

[0039] When the hole of the external pipe connecting ring aligns with the through hole 21, the positioning short tube 4 pops out under the elastic force of the first spring 5 and is inserted into the hole of the external pipe connecting ring, thereby achieving the effect of automatic alignment and automatic limiting when rotating the external pipe, thus saving the alignment time when connecting the cooling pump and the external pipe and achieving the purpose of rapid installation.

[0040] Furthermore, one end of the positioning short tube 4 extends to the outside of the connecting ring 2 and forms a chamfered portion 42, which facilitates the insertion of the positioning short tube 4 into the hole of the external pipe connecting ring and also facilitates the insertion of bolts into the positioning short tube 4. The other end of the positioning short tube 4 extends into the mounting hole 22 and is integrally formed with a limiting ring 41. The inner diameter of the limiting ring 41 is the same as the inner diameter of the positioning short tube 4, and the outer diameter of the limiting ring 41 is the same as the inner diameter of the mounting hole 22, which can limit the movement of the positioning short tube 4 and prevent the positioning short tube 4 from completely extending out of the movable groove 23 of the connecting ring 2, causing the positioning short tube 4 to detach.

[0041] The other end of the first spring 5 is fixed to the limiting ring 41.

[0042] Furthermore, a mating hole 31 is formed in the middle of the guide bucket 3, which is consistent with the outer diameter of the connecting ring 2 and the outer diameter of the external pipe connecting ring;

[0043] An installation groove 32 is provided on the upper part of the mating hole 31. An abutment block 6 is slidably connected in the installation groove 32. The tail end of the abutment block 6 forms a limiting baffle 61. The diameter of the limiting baffle 61 is the same as the inner diameter of the installation groove 32. One side of the limiting baffle 61 is elastically connected to the inner side wall of the installation groove 32 through a second spring 7.

[0044] With the setting of the abutment block 6 and the second spring 7, when the external pipe connecting ring abuts against the connecting ring 2, the abutment block 6 extends under the elastic force of the second spring 7 and abuts against the back side of the external pipe connecting ring away from the connecting ring 2. This, together with the positioning short pipe 4, tightens and limits the external pipe connecting ring, ensuring that it no longer rotates and preventing it from falling off. This makes it convenient for workers to temporarily loosen the external pipe for bolt installation and connection, which is conducive to quick installation by a single person and is more convenient to use.

[0045] Furthermore, multiple positioning short tubes 4 and multiple abutment blocks 6 are provided. Each positioning short tube 4 corresponds to a multiple through hole 21. Multiple abutment blocks 6 are staggered between multiple positioning short tubes 4. The staggered arrangement of abutment blocks 6 and positioning short tubes 4 can avoid interference of abutment blocks 6 with the installation and disassembly of bolts, thereby ensuring the smooth installation and disassembly of the cooling pump and external pipeline.

[0046] The working principle of this utility model is as follows: In daily use, when connecting the external pipe to the connecting pipe 11, the operator only needs to hold the external pipe and place the external pipe connector in the guide bucket 3, and then move it to the side of the connecting pipe 11. Under the guidance of the guide bucket 3, the external pipe connecting ring will automatically align with the connecting ring 2 on the same axis. Then, by rotating the external pipe, the hole on the external pipe connecting ring will correspond to the position of the through hole 21 during the rotation. At this time, the positioning short tube 4 will pop out under the elastic force of the first spring 5 and be inserted into the hole of the external pipe connecting ring to limit the movement of the external pipe connecting ring and complete the alignment. Then, the operator only needs to insert the bolt through the hole of the external pipe connecting ring and the through hole 21 to fix the external pipe to the connecting pipe 11. This saves the operator time in finding the correct position when connecting the external pipe, thereby improving the connection efficiency and facilitating the installation of the cooling pump. When disassembling, only the bolt needs to be removed, and disassembly is also convenient.

[0047] In addition, when the external pipe connecting ring abuts against the connecting ring 2, the abutting block 6 extends under the elastic force of the second spring 7 and abuts against the back side of the external pipe connecting ring away from the connecting ring 2, thereby cooperating with the positioning short pipe 4 to tighten and limit the external pipe connecting ring, ensuring that it no longer rotates and preventing it from falling off. This makes it convenient for workers to temporarily loosen the external pipe for bolt installation and connection, which is conducive to a single person to achieve quick installation operation and is more convenient to use.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
