Description

Technical Field

[0001] The utility model relates to the technical field of water pump connectors, in particular to a quick-release water pump connector. Background Art

[0002] A water pump connector, also known as a pump body connector, is an important component installed at the inlet and outlet of a water pump, used to connect the water pump and the pipeline, so that water flow can be smoothly guided from the water pump to the pipeline. The water pump connector plays a role of fixed connection between the water pump and the pipeline, and is a transition part between the water pump and the water pipe.

[0003] The utility model with the publication number CN211175824U discloses a quick-installation connector for a water pump. By using the connection and fixation method of a buckle, the quick docking of the water pump water outlet and the pipe connector can be realized. The installation is simple and convenient, and no other auxiliary tools are required. It is very suitable for places with limited field conditions and when water is urgently needed in case of disasters. The entire installation process can be completed in a very short time, and the water pump can immediately pump water to meet the water supply demand.

[0004] However, in the above scheme, the connection between pipes only relies on the buckle structure to play a fixing role. Since the buckle structure lacks measures to prevent loosening, and the pipeline is prone to vibration due to the impact of the liquid on the pipe wall during liquid transportation, the pipeline is extremely easy to loosen at the connection during use, resulting in liquid leakage. In addition, due to the lack of limiting measures, the pipes are prone to relative rotation due to torque, which brings inconvenience to use. In the above scheme, the relative rotation may also cause the buckle connection to fail. Therefore, in view of the above problems, a quick-release water pump connector is proposed. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a quick-release water pump connector. The water pump connector realizes quick connection through the insertion between the receiving joint and the plug joint, which can greatly improve the rate of the connection work. Moreover, there is a large contact and sealing area between the insertion pipe and the insertion interface, which can significantly improve the sealing performance of the connection. At the same time, after the joints are connected, the receiving joint and the plug joint can be tightened by inserting and rotating the tightening pull rod into the fitting block, and the tightening force can be continuously and stably maintained, and it is not easy to cause connection failure due to vibration. In addition, the anti-torsion member can prevent relative rotation between the pipe bodies through the clamping action between the insertion strip and the groove plate, solving the technical problems in the prior art that there are no measures to prevent loosening at the connection, it is easy to cause connection failure due to vibration, and it is easy to have relative rotation between pipes due to torque, which brings inconvenience to use.

[0006] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0007] A quick-release joint for a water pump, comprising a pipe body, with a socket joint and a plug joint connected to its two ends respectively. Among them, an insertion port is provided on the socket joint, a plug pipe is connected to the plug joint, a locking member for preventing the socket joint and the plug joint from separating from each other, which includes a tightening pull rod and a mating block, and a torsion-resistant member for bearing the torque received at the connection of the pipe body, which includes an insertion bar and a groove plate.

[0008] Through the above structural form, the quick connection is realized by the insertion action between the socket joint and the plug joint, which can greatly improve the rate of the connection work, and there is a large contact and sealing area between the plug pipe and the insertion port, which can significantly improve the sealing performance of the connection. At the same time, after the joint is connected, the socket joint and the plug joint can be tightened by inserting the tightening pull rod into the mating block and then rotating, and the tightening force can be continuously and stably maintained, and it is not easy to cause connection failure due to vibration. In addition, the torsion-resistant member can prevent relative rotation between the pipe bodies by the clamping action between the insertion bar and the groove plate.

[0009] In a possible implementation manner, a plurality of water-blocking rings are fixedly arranged on both the inner and outer walls of the insertion port. The water-blocking rings are circular ring structures made of rubber material and are embedded in the insertion port.

[0010] Through the above structural form, after the plug pipe is inserted into the insertion port, due to the extrusion effect, the water-blocking rings will be compressed and deformed into a series of closed rings, further improving the sealing performance of the connection and avoiding water seepage at the connection.

[0011] In a possible implementation manner, the tightening pull rod is fixedly arranged on the plug joint, and the mating block is fixedly arranged on the socket joint.

[0012] Through the above structural form, the tightening effect can be achieved by the clamping between the tightening pull rod and the mating block, so that the plug joint and the socket joint are tightly connected.

[0013] In a possible implementation manner, the tightening pull rod includes a sliding cylinder, a pull rod is slidably arranged in the sliding cylinder, a clamping block is fixedly connected to one end of the pull rod away from the pipe body, and the width of the clamping block is numerically the same as the diameter of the pull rod.

[0014] Through the above structural form, since the pull rod can slide back and forth in the sliding cylinder, the clamping block can move back and forth to realize the clamping and separation from the mating block.

[0015] In a possible implementation manner, a dial is fixedly connected to one end of the pull rod away from the clamping block, and a tightening spring is sleeved outside the pull rod, and both ends of the tightening spring respectively abut against the dial and the sliding cylinder.

[0016] With the above structural form, when the pull rod is pushed forward to make the clamping block and the mating block engage with each other, the tension spring is continuously in a compressed and deformed state. Therefore, it will continuously apply a pulling force to the clamping block, making it in close contact with the mating block, and it is not easy to separate the clamping block from the mating block due to vibration, resulting in connection failure.

[0017] In a possible implementation manner, a through groove is formed in the middle of the mating block, and the width of the through groove is numerically the same as the diameter of the pull rod. An anti - detachment wedge block is fixedly arranged at one end of the through groove far from the sliding cylinder.

[0018] With the above structural form, during connection, the clamping block passes through the through groove and rotates after completely passing through until the clamping block completely crosses the anti - detachment wedge block. At this time, under the pulling force of the tension spring, the clamping block is in close contact with the mating block and engages with each other. And due to the existence of the anti - detachment wedge block, the clamping block cannot rotate back, so the firmness of the connection can be ensured.

[0019] In a possible implementation manner, the insert bar is fixedly arranged on the plug connector, the groove plate is fixedly arranged on the receiving head, and a slot with the same width as the insert bar is formed in the middle of the groove plate.

[0020] With the above structural form, the clamping between the insert bar and the groove plate can play a role in sharing torque, preventing relative rotation between the pipe bodies and affecting the normal use of the connection.

[0021] In a possible implementation manner, chamfers are formed on both sides of the front end of the insert bar, and chamfers are formed at the slot opening of the slot.

[0022] With the above structural form, with the setting of the chamfers, the insert bar can be inserted into the slot more conveniently, reducing the operation difficulty during connection.

[0023] In summary, the utility model includes the following beneficial technical effects:

[0024] The quick connection is realized by the plug - in action between the receiving head and the plug connector, which can greatly improve the rate of the connection work. And there is a large contact and sealing area between the insertion pipe and the insertion interface, which can significantly improve the sealing performance of the connection. At the same time, after the joints are connected, by inserting and rotating the tightening pull rod into the mating block, the receiving head and the plug connector can be tightened, and the tightening force can be continuously and stably maintained, not easily causing connection failure due to vibration. In addition, the torsion - resistant member can prevent relative rotation between the pipe bodies through the clamping between the insert bar and the groove plate. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0032] The technical solutions in the embodiments of the present application are to solve the problems in the above - mentioned background technology, and the general idea is as follows:

[0033] As Figure 1 - Figure 2 shown, a quick - release joint for a water pump provided in this embodiment includes a pipe main body 1, with a spigot joint 2 and a socket joint 3 respectively connected to both ends thereof. Among them, a socket 21 is provided on the spigot joint 2, an insertion pipe 31 is connected to the socket joint 3, a locking member 4 for preventing the spigot joint 2 and the socket joint 3 from separating from each other, which includes a tightening pull rod 41 and a mating block 42, and an anti - torsion member 5 for bearing the torque received at the connection of the pipe main body 1, which includes an insertion strip 51 and a groove plate 52. Through the above - mentioned structural form, the quick connection is realized through the plug - in action between the spigot joint 2 and the socket joint 3, which can greatly improve the connection work rate, and there is a large contact and sealing area between the insertion pipe 31 and the socket 21, which can significantly improve the sealing performance of the connection. At the same time, after the joints are connected, the spigot joint 2 and the socket joint 3 can be tightened by inserting the tightening pull rod 41 into the mating block 42 and then rotating, and the tightening force can be continuously and stably maintained, and it is not easy to cause connection failure due to vibration. In addition, the anti - torsion member 5 can prevent relative rotation between the pipe main bodies 1 through the clamping action between the insertion strip 51 and the groove plate 52.

[0034] As Figure 4As shown in the figure, a number of water-blocking rings 22 are fixedly arranged on both the inner and outer walls of the insertion port 21. The water-blocking rings 22 are circular ring structures made of rubber material and are embedded in the insertion port 21. Through the above structural form, after the insertion tube 31 is inserted into the insertion port 21, due to the extrusion effect, the water-blocking rings 22 will be compressed and deformed into a series of closed rings, further improving the tightness of the connection and preventing water seepage at the connection.

[0035] As Figure 3 - Figure 5 As shown in the figure, the tightening pull rod 41 is fixedly arranged on the plug connector 3, and the mating block 42 is fixedly arranged on the socket 2. Through the above structural form, the tightening effect can be achieved by the clamping between the tightening pull rod 41 and the mating block 42, so that the plug connector 3 and the socket 2 are tightly connected. Among them, the tightening pull rod 41 includes a sliding cylinder 411, a pull rod 412 is slidably arranged in the sliding cylinder 411, a clamping block 413 is fixedly connected to the end of the pull rod 412 away from the pipe body 1, and the width of the clamping block 413 is numerically the same as the diameter of the pull rod 412. Through the above structural form, since the pull rod 412 can slide back and forth in the sliding cylinder 411, the clamping block 413 can move back and forth to realize the clamping and separation with the mating block 42.

[0036] In addition, a dial 414 is fixedly connected to the end of the pull rod 412 away from the clamping block 413, and a tightening spring 415 is sleeved outside the pull rod 412. The two ends of the tightening spring 415 respectively abut against the dial 414 and the sliding cylinder 411. Through the above structural form, when the pull rod 412 is pushed forward to make the clamping block 413 and the mating block 42 engage with each other, the tightening spring 415 is continuously in a compressed and deformed state. Therefore, it will continuously apply a pulling force to the clamping block 413, making it in close contact with the mating block 42, and it is not easy to cause the connection to fail due to the separation of the clamping block 413 and the mating block 42 caused by vibration.

[0037] A through groove 421 is opened in the middle of the mating block 42, and the width of the through groove 421 is numerically the same as the diameter of the pull rod 412. An anti-disengagement wedge block 422 is fixedly arranged at the end of the through groove 421 away from the sliding cylinder 411. Through the above structural form, during connection, the clamping block 413 passes through the through groove 421 and rotates after passing through completely until the clamping block 413 completely crosses the anti-disengagement wedge block 422. At this time, under the pulling force of the tightening spring 415, the clamping block 413 is in close contact with the mating block 42 and engages with each other. And due to the existence of the anti-disengagement wedge block 422, the clamping block 413 cannot rotate back, so the firmness of the connection can be ensured.

[0038] As Figure 3 - Figure 4As shown, the insert bar 51 is fixedly arranged on the insertion joint 3, the groove plate 52 is fixedly arranged on the receiving joint 2, and a slot 521 with the same width as the insert bar 51 is formed in the middle of the groove plate 52. Through the above structural form, the clamping connection between the insert bar 51 and the groove plate 52 can play a role in sharing torque, preventing relative rotation between the pipe bodies 1 and affecting the normal use of the connection.

[0039] Among them, chamfers 501 are formed by processing on both sides of the front end of the insert bar 51, and chamfers 501 are formed by processing at the notch of the slot 521. Through the above structural form, with the setting of the chamfers 501, the insert bar 51 can be inserted into the slot 521 more conveniently, reducing the operation difficulty during connection.

[0040] The usage principle and usage process of the present utility model:

[0041] The quick connection is realized by the insertion connection between the receiving joint 2 and the insertion joint 3, which can greatly improve the connection work rate, and there is a large contact and sealing area between the insertion pipe 31 and the insertion port 21, which can significantly improve the sealing performance of the connection. After the insertion pipe 31 is inserted into the insertion port 21, due to the extrusion effect, the water blocking ring 22 will be compressed and deformed into a series of closed rings, further improving the tightness of the connection and avoiding water seepage at the connection.

[0042] After the joints are connected, the receiving joint 2 and the insertion joint 3 can be tightened by inserting and rotating the tightening pull rod 41 into the fitting block 42, and the tightening force can be continuously and stably maintained, and it is not easy to cause connection failure due to vibration. Specifically, the clamping block 413 passes through the through groove 421 and rotates after completely passing through until the clamping block 413 completely crosses the anti - detachment wedge block 422. At this time, under the pulling force of the tightening spring 415, the clamping block 413 is in close contact with the fitting block 42 and is mutually clamped, and due to the existence of the anti - detachment wedge block 422, the clamping block 413 cannot rotate back, so the firmness of the connection can be ensured.

[0043] In addition, the torsion - resistant member 5 can prevent relative rotation between the pipe bodies 1 through the clamping connection between the insert bar 51 and the groove plate 52.

[0044] Finally, it should be noted that: Obviously, the above - mentioned embodiments are only examples for clearly explaining the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
