DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0026] like Figures 1 to 4As shown, a connection interface of a PU cloth water hose for agricultural irrigation comprises a water hose 1, a connecting piece 2 fixedly connected to one end of the water hose 1, a limiting mechanism 31 being arranged on the outer wall of the connecting piece 2, a connecting sealing mechanism 32 being arranged inside the connecting piece 2, the limiting mechanism 31 comprising a hinge seat 311 fixedly connected to the outer wall of the connecting piece 2, a rotating groove being provided inside the hinge seat 311, a torsion spring 312 being fixedly connected to the inner wall of the rotating groove, a rotating shaft 313 being fixedly connected to the end of the torsion spring 312 away from the inner wall of the rotating groove, an outer wall of the rotating shaft 313 being rotatably arranged on the inner wall of the rotating groove, a rotating connecting plate 314 being fixedly connected to the outer wall of the rotating connecting plate 314, a clamping plate 315 being fixedly connected to the outer wall of one end of the rotating connecting plate 314, a force-bearing slope 316 being provided on the outer wall of the clamping plate 315, a clamping plate 317 being fixedly connected to the outer wall of one end of the connecting piece 2, a limiting hole 318 being provided on the outer wall of the clamping plate 317, and the outer wall of the clamping plate 315 being clamped and limited inside the limiting hole 318.

[0027] Furthermore, a hinge seat 311 is provided on a single outer wall of the connecting member 2. When the connecting member 2 is in the connected state, the direction of the hinge seat 311 is in a relative direction, so that the hinge seat 311 can be distributed in an upper and lower relative direction after the connection is completed, so as to facilitate subsequent disassembly and pressing.

[0028] Furthermore, the inner wall of the limiting hole 318 is slightly larger than the outer wall of the clamping plate 315 , so that when the clamping plate 315 rotates up and down, there is a certain space so that the clamping plate 315 can be clamped on the inner wall of the limiting hole 318 .

[0029] Furthermore, the inner wall of the rotating groove arranged inside the hinge seat 311 fits snugly with the outer wall of the rotating shaft 313, thereby ensuring the close fit between the outer wall of the rotating shaft 313 and the inner wall of the rotating groove, thereby ensuring the stability of the rotating shaft 313 during the rotation of the inner wall of the rotating groove.

[0030] The connection sealing mechanism 32 includes a limiting card plate 321 fixedly connected to the inside of the connecting member 2, a card frame 322 is fixedly connected to one side of the limiting card plate 321 inside the connecting member 2, a sealing groove 323 is provided inside the connecting member 2, a rubber ring 324 is fixedly connected to one end of the water hose 1, and a locking rubber ring 325 is fixedly connected to the inner wall of the connecting member 2.

[0031] Furthermore, there are two limit clamping plates 321 and two clamping frames 322, which are symmetrically distributed inside the connector 2, so that the two sides of the connector 2 can be supported and limited simultaneously, thereby ensuring stability after clamping.

[0032] Furthermore, the outer wall of the limiting clamping plate 321 is matched with the inner wall of the clamping frame 322, so as to ensure the tightness of the inner wall of the limiting clamping plate 321 after being clamped on the inner wall of the clamping frame 322, thereby ensuring the stability of the initial clamping connection.

[0033] The implementation principle of the connection interface of a PU cloth water hose for agricultural irrigation in this embodiment is as follows: first, the two connecting parts 2 are connected to each other, and then the rotation is limited. During the rotation process, the connecting part 2 will drive the hinge seat 311 to rotate. When the hinge seat 311 rotates, it will drive the rotating connecting plate 314 and the clamping plate 315 to rotate. During the rotation of the clamping plate 315, the force-bearing slope 316 provided on its outer wall will contact and be squeezed by the clamping plate 317. The squeezed clamping plate 315 will rotate through the rotation between the rotating shaft 313 and the rotating groove on the inner wall of the hinge seat 311, so that the clamping plate 315 is gradually higher than the clamping plate 315, and then with the continued rotation, the clamping plate 315 will move to the top of the limiting hole 318. When the displacement When the locking cam 315 is in the locked state, the locking cam 315 is in the locked state, and the locking cam 315 is in the locked state.

[0034] When connecting, first align the card frame 322 on the other connecting part 2 with the through groove between the upper limit card plate 321 and the card frame 322 of the current connecting part 2, and then insert it into it. Then, the connecting parts 2 on both sides can be rotated in opposite directions so that the outer wall of the limit card plate 321 rotates to the internal card groove of the card frame 322, and the preliminary limit card connection operation between the connecting parts 2 can be completed. At the same time, when the docking is completed, the rubber rings 324 on both sides will contact and dock with each other, and the interface of the water hose 1 will be initially sealed. At the same time, during the docking process of the water hose 1, the engaging rubber ring 325 will be inserted into the sealing groove 323, further sealing the interface of the water hose 1 and improving the sealing effect.
