Description

Technical Field

[0001] The utility model belongs to the technical field of water pump pipelines, and particularly relates to a quick connection assembly for pump pipes of a water pump. Background Technique

[0002] The water pump pipeline is a key component in the water pump system. It includes a series of pump pipes, valves, joints, and other auxiliary equipment for transporting the pumped liquid to the target location. Among them, the pump pipe is responsible for transporting the fluid pushed by the water pump to the place where it needs to be transported. However, in actual situations, the pump pipes in the water pump pipeline are spliced in series by multiple pump pipes. When splicing, at present, bolts are mainly used to lock the flanges at the ends of adjacent pump pipes for installation. However, this installation method requires operating several bolts for locking, and the operation is relatively troublesome. Moreover, in the maintenance and installation of pump pipes in the prior art, the two ends of the pump pipe often cannot be butted with the flanges of adjacent pump pipes, resulting in a low error tolerance rate during installation.

[0003] Therefore, we provide a quick connection assembly for pump pipes of a water pump to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quick connection assembly for pump pipes of a water pump. Through the cooperation of the insertion strip and the mounting ring, the connection between two pump pipe bodies can be completed without operating several bolts. Moreover, the elastic sealing tube seals between the two connecting pipes, enabling the two connecting pipes to move relative to each other to facilitate adapting to the installation distance of the pump pipe body. This solves the problems that in the prior art, when installing pump pipes, several bolts need to be operated to lock multiple flanges, the operation is relatively troublesome, and in the maintenance and installation of pump pipes in the prior art, the two ends of the pump pipe often cannot be butted with the flanges of adjacent pump pipes, resulting in a low error tolerance rate during installation.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model relates to a quick connection assembly for pump pipes of a water pump, which comprises a pump pipe body. There are two pump pipe bodies arranged coaxially. Installation rings are fixed at the inner ends of the two pump pipe bodies. Connecting pipes arranged coaxially are arranged on the inner sides of the two pump pipe bodies. Connection rings are fixed at the outer ends of the two connecting pipes. A boss is fixed on the outer side wall of the connection ring. An insertion bar penetrates through the boss, and the inner side wall of the insertion bar abuts against the outer side wall of the installation ring. A left circular plate is fixed on the right side of the outer peripheral wall of the connecting pipe on the left. An elastic sealing pipe is arranged outside the connecting pipe on the left corresponding to the right side of the left circular plate. An end plate is fixed at the left end of the connecting pipe on the right. A right circular plate is fixed on the outer peripheral wall of the connecting pipe on the right corresponding to the right side of the end plate. The right circular plate is fixedly connected with the left circular plate through bolts.

[0007] The utility model is further arranged such that an elastic sealing gasket is arranged between the installation ring and the corresponding connection ring. Positioning rods are uniformly fixed on the left wall of the connection ring, and the outer ends of the positioning rods pass through the corresponding elastic sealing gaskets and are inserted into the corresponding installation rings.

[0008] The utility model is further arranged such that an adjusting rod is arranged outside the insertion bar. A baffle is fixed at the inner end of the adjusting rod, and the baffle is fixedly connected with the corresponding insertion bar.

[0009] The utility model is further arranged such that a support spring is arranged outside the adjusting rod. An installation plate is arranged outside the support spring, and the installation plate is fixedly connected with the corresponding boss.

[0010] The utility model is further arranged such that the two ends of the support spring respectively abut against the corresponding installation plate and the baffle, and a pinch block is fixed at the outer end of the adjusting rod.

[0011] The utility model is further arranged such that support plates are fixed on the left and right sides inside the elastic sealing pipe, and elastic members are fixedly arranged in a circumferential array between the two support plates.

[0012] The utility model is further arranged such that an installation sleeve is fixed on the outer side of the elastic sealing pipe corresponding to the right wall of the left circular plate. The end plate is in clearance fit with the installation sleeve, and a nut is threadedly connected to the outside of the bolt corresponding to the right side of the left circular plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model fixes the relative position between the pump pipe body and the corresponding connecting pipe by setting an installation ring and insertion strips. After the installation ring contacts the corresponding elastic sealing gasket, the insertion strips are inserted into the corresponding bosses, and the inner side walls of the insertion strips abut against the corresponding installation rings, so that the connection can be achieved without bolts, and the operation is simpler. This solves the problem that in the prior art, when installing the pump pipe, it is necessary to operate several bolts to lock multiple flanges, which is rather troublesome.

[0015] 2. The utility model sets an elastic sealing pipe, and the support plate is supported by an elastic member. Under the combined action of the elastic sealing pipe and the support plate, the left and right side walls of the elastic sealing pipe always abut against the corresponding left circular plate and right circular plate to maintain a sealed state, enabling the two connecting pipes to move relative to each other by a certain distance. This distance facilitates the docking of the two ends of the connecting pipe with the corresponding pump pipe body for installation after maintenance, solving the problem that in the prior art, when maintaining and installing the pump pipe, the two ends of the pump pipe often cannot be docked with the flanges of the adjacent pump pipes, resulting in a low error tolerance rate during installation.

[0016] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 2

[0034] Please refer to Figure 1 、 2 Figures 4 and 5, which are the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but different from the first embodiment: A left circular plate 302 is fixed to the right side of the outer peripheral wall of the connecting pipe 3 on the left side. An elastic sealing tube 6 is arranged outside the connecting pipe 3 on the left side corresponding to the right side of the left circular plate 302 (the connection length formed by the two connecting pipes 3 in the figure is in the minimum state). The specification of the elastic sealing tube 6 needs to have a redundant space, that is, when the two connecting pipes 3 move away from each other, the left and right side walls of the elastic sealing tube 6 can still abut against the corresponding left circular plate 302 and end plate 303 to ensure the sealing performance. A end plate 303 is fixed to the left end of the connecting pipe 3 on the right side.
