Description

Technical Field

[0001] This utility model relates to pump bodies, and more particularly to a quick-connect pump body that can be quickly positioned during assembly. Background Technology

[0002] As the name suggests, a pump body is a type of pump used for pumping water. When connecting a water supply pipe to an existing pump body, the user must first control the end of the pipe and connect it to the pump body, and ensure that the pipe fits snugly against the pump body. Secondly, the pipe connection angle must be adjusted so that the bolt holes on the pipe are aligned with the bolt holes on the pump body before bolts can be inserted for fixing. Therefore, adjusting the bolt hole position and maintaining the fit between the pipe and the pump body can be very difficult.

[0003] Chinese Patent No. CN202322233256.4 discloses a quick-connect pump body that can quickly align screw holes. It determines the relative position of the pipeline and the pump body by setting a snap-fit ​​pin on the pipeline and cooperating with the snap-fit ​​component on the pump body, thus facilitating the subsequent installation of bolts between the pipeline and the pump body. It is worth noting that after the indicator passes the protruding part on the snap-fit ​​pin, the second spring can facilitate the indicator to spring back downwards. The first spring can facilitate the separation of the snap-fit ​​component and the snap-fit ​​pin and can drive the snap-fit ​​component to reset after separation. However, since the elasticity of the spring itself will deteriorate during the continuous compression and reset process, and both the first and second springs are located in the pump body, if the first and second springs need to be repaired or even replaced, the pump body needs to be replaced or disassembled, which causes inconvenience to use. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-connect pump body that can be quickly positioned during assembly by assembling the pipe and the connector to complete the connection between the connector and the body, so that some accessories used for assembly are located inside the connector, thereby reducing the need to disassemble the pump body during maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a pump body and a pipe connected to the pump body, and also includes a connector made of a material that is prone to deformation. The connector is located between the pipe and the pump body, and the connector is detachably connected to the pipe. The connector is provided with a plurality of insertion holes, and the pump body is provided with screw holes corresponding to each insertion hole.

[0006] The present invention is further configured such that: a first sealing ring is provided on the connector, an installation groove is provided on the pump body corresponding to the first sealing ring, and a second sealing ring is provided on the pump body inside the first sealing ring.

[0007] The present invention is further configured such that: the first sealing ring includes an inner mating surface, the mating surface is radially downward and axially inward inclined, and the second sealing ring includes a contact surface that abuts against the mating surface.

[0008] The present invention is further configured such that: the connector includes a mating section, the inner wall of the mating section is circumferentially fitted with the pump body, a limiting ring is provided protruding from the inner side of the mating section, and a limiting groove is provided on the pump body corresponding to the limiting ring.

[0009] The present invention is further configured such that: the pipeline includes a limiting section located behind the joint and a connecting section for inserting the joint; the joint includes a connecting groove for inserting the connecting section; the diameter of the limiting section is larger than the diameter of the connecting groove; and the connecting section is detachably connected to the joint.

[0010] The present invention is further configured such that: the connector includes an installation section located inside the pump body, and the upper and lower sides of the installation section are provided with mating slots. The installation section is provided with mating blocks and mating springs made of easily deformable material in each mating slot. One end of each mating spring is fixedly connected to the installation section and the other end is fixedly connected to the mating block. The connecting section is provided with connecting blocks made of easily deformable material in each mating slot. The connecting blocks abut against the corresponding mating blocks.

[0011] The present invention is further configured such that each mating plug also includes a fitting section located above the corresponding connecting plug and fitting against the upper end surface of the connecting plug.

[0012] By adopting the above technical solution, since the connector and pump body are detachably connected, and the pipeline and connector are detachably connected, compared to the pipeline directly connected to the pump body, the connection to the connector allows for separation and connection during pipeline assembly and disassembly, without the need for cooperation with the pump body. Therefore, the part that is detached from the pipeline is located on the pipeline rather than the pump body. This allows for maintenance of this part during long-term use by removing the connector from the pump body, or replacing the connector, instead of disassembling or replacing the pump body. This effectively improves the service life of the pump body. Furthermore, by inserting bolts into the corresponding holes and engaging with the corresponding threaded bolts, the connector and pump body can be fitted together, thus facilitating the assembly of the pump body and connector.

[0025] 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.

[0026] like Figures 1-8 As shown, this utility model discloses a quick-connect pump body that can be quickly positioned during assembly. It includes a pump body 1 and a pipe 2 connected to the pump body 1. An impeller (existing technology, not shown in the figure) is installed inside the pump body 1. The high-speed rotation of the impeller generates centrifugal force, causing the liquid at one end of the impeller to move towards the other end (this is existing technology and will not be specifically described here). It also includes a connector 3 made of a deformable material such as rubber. The connector 3 is located between the pipe 2 and the pump body 1. The connector 3 and the pipe 2 are detachably connected by fastening, bolts, etc. The connector 3 has several insertion holes 31, and the pump body 1 has screw holes 11 corresponding to each insertion hole 31. Because the connector 3 and the pump body 1 are detachably connected, and the pipe 2 and the connector 3 are detachably connected, compared to… For pipe 2, which is directly connected to pump body 1, it is now connected to connector 3 instead. During the disassembly and assembly of pipe 2, it is separated from and connected to connector 3 without having to cooperate with pump body 1. Therefore, the part that is disassembled from pipe 2 is located on pipe 2 rather than pump body 1. This allows for maintenance of this part during long-term use by removing connector 3 from pump body 1, or replacing connector 3, instead of disassembling or replacing pump body 1. This effectively improves the service life of pump body 1. Furthermore, by inserting bolts (not shown in the figure) into the corresponding holes 31 and threading them into the corresponding screw holes 11, connector 3 and pump body 1 can be connected, thus completing the assembly of pump body 1 and connector 3 and providing convenience for the assembly of pump body 1 and connector 3.

[0027] The connector 3 is provided with a first sealing ring 32, and the pump body 1 is provided with an installation groove 12 corresponding to the first sealing ring 32. The pump body 1 is provided with a second sealing ring 13 inside the first sealing ring 32. Since the connector 3 and the pump body 1 are detachably connected, the design of the first sealing ring 32 and the second sealing ring 13 increases the sealing between the pump body 1 and the connector 3, thereby reducing the leakage of liquid between the pump body 1 and the pipe 2 through the connection between the pump body 1 and the connector 3.

[0028] Preferably, the first sealing ring 32 includes an inner mating surface 321, which is radially downward and axially inward. The second sealing ring 13 includes a contact surface 131 that abuts against the mating surface 321. After the connector 3 is installed into the pump body 1, the mating surface 321 of the first sealing ring 32 can contact the contact surface 131 of the second sealing ring 13, thereby stabilizing and reducing liquid leakage from the pump body 1 and the connector 3. At the same time, due to the presence of the mating surface 321, the outline shape of the first sealing ring 32 is constricted from the outside to the inside, thereby allowing the first sealing ring 32 to smoothly enter the mounting groove 12 and cooperate with the second sealing ring 13.

[0029] The connector 3 includes a mating section 33, the inner wall of which is circumferentially fitted to the pump body 1. A limiting ring 331 protrudes from the inner side of the mating section 33, and a limiting groove 14 is provided on the pump body 1 corresponding to the limiting ring 331. Since the limiting ring 331 located inside the mating section 33 of the connector 3 will fall into the limiting groove 14 of the pump body 1, the limiting ring 331 will not separate from the limiting groove 14 without the action of external force. Thus, before the bolt is installed, the existence of the mating section 33 enables the radial position of the connector 3 and the pump body 1 to be determined, thereby facilitating the insertion of the bolt into the insertion hole 31 and its engagement with the screw hole 11.

[0030] Furthermore, the pipe 2 includes a limiting section 21 located behind the connector 3 and a connecting section 22 for inserting the connector 3. The connector 3 includes a connecting groove 34 for inserting the connecting section 22. The diameter of the limiting section 21 is larger than the diameter of the connecting groove 34. The connecting section 22 and the connector 3 are detachably connected by means of fastening or other methods. Since the diameter of the limiting section 21 is larger than the diameter of the connecting groove 34, the pipe 2 is inserted from the side away from the pump body 1 through the connecting groove 34 close to the pump body 1. When the limiting section 21 abuts against the inner end face of the connector 3, the axial position of the pipe 2 and the connector 3 is determined. After the detachable connection between the connecting section 22 and the connector 3 is completed, the liquid in the pipe 2 can flow towards the inside of the pump body 1.

[0031] The connector 3 includes an installation section 35 located within the pump body 1. The installation section 35 has mating slots 351 on both its upper and lower sides. Within each mating slot 351, the installation section 35 has mating blocks 352 and mating springs 353 made of easily deformable materials such as rubber. One end of each mating spring 353 is fixedly connected to the installation section 35, and the other end is fixedly connected to the mating block 352. The connecting section 22 has connecting blocks 221 made of easily deformable materials within each mating slot 351. Each connecting block 221 abuts against its corresponding mating block 352. When the pipe 2 is inserted into the connector 3, the connecting blocks 221 on the connecting section 22 of the pipe 2 need to be pressed inwards to enter the installation section. When segment 35 reaches the vicinity of the mating slot 351, it can compress the mating spring 353 to drive the mating block 352 to move outward, thereby allowing each connecting block 221 to enter the corresponding mating slot 351. At this time, the compression of the mating spring 353 is released, and the mating block 352 moves inward under the action of the mating spring 353 to achieve abutment with the mating block 352. Therefore, without the action of external force, the connecting segment 22 can be stably connected with the mounting segment 35. When it is necessary to separate the connecting segment 22 from the mounting segment 35, each mating block 352 is pushed outward to compress the corresponding mating spring 353, thereby causing each connecting block 221 to deform downward to the mating slot 351 and separate from it, and then separate from the connector 3.

[0032] Preferably, each mating plug 352 further includes a mating section 3521 located above the corresponding connecting plug 221 and in contact with the upper surface of the connecting plug 221. Since the mating section 3521 will be located above the connecting plug 221 during the connection process between the connecting section 22 and the mounting section 35, the contact area between the mating plug 352 and the connecting plug 221 is increased, thereby further improving the mating between the connecting plug 221 and the corresponding mating plug 352 in the corresponding mating slot 351, and improving the connection stability between the connecting section 22 and the mounting section 35.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
