[0024] According to an embodiment of the utility model, a quick-connect straight-through is provided.

[0025] Please refer to the instruction manual Figure 1-5 According to an embodiment of the utility model, a quick-connect straight-through comprises a straight cylinder 1, a sealing ring 2 is provided at the inner upper end of the straight cylinder 1, a packing 3 is provided on the lower side of the sealing ring 2, a buckle 4 is installed at the inner lower end of the straight cylinder 1, a sealing block 5 is slidably installed on the inner side of the straight cylinder 1, a wire sleeve 8 is spirally connected to the right end of the straight cylinder 1, a fixing frame 9 is fixedly connected to the inner side of the wire sleeve 8, a connecting piece 15 is provided on the right side of the wire sleeve 8, a front half ring 10 is installed at the outer front end of the wire sleeve 8 and the connecting piece 15, and a rear half ring 11 is installed at the outer rear end of the wire sleeve 8 and the connecting piece 15.

[0026] When the straight-through set is used, the sealing ring 2 and the packing 3 are placed in the straight cylinder 1 in sequence, and finally the buckle 4 can be directly inserted into the inner side of the straight cylinder 1. Because the buckle 4 is made of plastic, it has certain strength and elasticity and can be engaged with the straight cylinder 1 to complete the quick connection; the straight cylinder 1 is connected by screwing the wire sleeve 8. During this process, the fixing frame 9 in the wire sleeve 8 squeezes the sealing block 5. After the sealing block 5 is separated from the inner wall of the straight cylinder 1, the water flow can enter the wire sleeve 8, and the connecting piece 15 is taken out and aligned with the wire sleeve 8. The front half ring 10 and the rear half ring 11 are taken out and buckled on the outside of the wire sleeve 8 and the connecting piece 15. After the rotating rod 13 is rotated, the tightening knob 14 is screwed so that the front half ring 10 and the rear half ring 11 clamp and fix the wire sleeve 8 and the connecting piece 15, so that the straight-through pipeline has a three-way capability and can achieve quick connection capability.

[0027] In one embodiment, please refer to the attached specification Figure 1-5 As a further solution of the utility model, the straight tube 1 is made of HPB57-3 material, the buckle 4 is made of plastic material, the sealing ring 2 is made of EPDM material, and the filler 3 is made of PE material.

[0028] The straight tube 1 and the buckle 4 have high strength and can adapt to water pressure. The sealing ring 2 and the filler 3 can fill the gap between the straight tube 1 and the buckle 4. The buckle 4 has a certain elasticity, thereby achieving quick connection with the straight tube 1.

[0029] In another embodiment, please refer to the attached Figure 1-5 As a further solution of the utility model, a telescopic rod 6 is fixedly connected to the center of the sealing block 5, a spring 7 is provided on the outside of the telescopic rod 6, and the telescopic rod 6 is fixedly connected to the inner wall of the straight tube 1.

[0030] The spring 7 and the telescopic rod 6 cooperate to realize the engagement of the sealing block 5 and the straight tube 1, thereby realizing the rapid switching between water discharge and sealing.

[0031] In one embodiment, please refer to the attached specification Figure 1-5 As a further solution of the utility model, a connecting piece 12 is rotatably installed on the inner side of the front half ring 10 and the rear half ring 11, and two grooves are provided on the inner side of the front half ring 10 and the rear half ring 11. A rotating rod 13 is rotatably connected to the inner side of the rear half ring 11, and a tightening knob 14 is spirally connected to the outer front end of the rotating rod 13.

[0032] By screwing the tightening knob 14, the front half ring 10 and the rear half ring 11 are brought closer to each other, and the wire sleeve 8 and the connecting piece 15 are clamped and positioned.

[0033] In another embodiment, please refer to the attached Figure 1-5 As a further solution of the utility model, the straight tube 1 is connected to the buckle 4, and the straight tube 1 is connected to the wire sleeve 8, and the diameter of the wire sleeve 8 is equal to the diameter of the connecting piece 15.

[0034] This allows the straight-through pipeline to have three-way switching and selection capabilities, and can adapt to more usage environments.

[0035] When in use, the sealing ring 2 and the filler 3 are placed in the straight tube 1 in sequence, and finally the buckle 4 can be directly inserted into the inner side of the straight tube 1. Since the buckle 4 is made of plastic, it has certain strength and elasticity and can be engaged with the straight tube 1 to complete the quick connection; the straight tube 1 is connected by screwing the wire sleeve 8. During this process, the fixing frame 9 in the wire sleeve 8 squeezes the sealing block 5. After the sealing block 5 is separated from the inner wall of the straight tube 1, the water flow can enter the wire sleeve 8, and the connecting piece 15 is taken out and aligned with the wire sleeve 8. The front half ring 10 and the rear half ring 11 are taken out and buckled on the outside of the wire sleeve 8 and the connecting piece 15. After the rotating rod 13 is rotated, the tightening knob 14 is screwed so that the front half ring 10 and the rear half ring 11 clamp and fix the wire sleeve 8 and the connecting piece 15, so that the straight-through pipeline has a three-way capability and can achieve quick connection capability.
