[0001] The present application relates to the reel technical field, especially to a water pipe reel. BACKGROUND

[0002] The water pipe reel is used to roll up the water pipe, and the existing water pipe reel is usually placed in a box body. When the water pipe reel is needed, the water pipe reel with the water pipe rolled up is taken out, and then the water pipe is pulled out, one end of which is connected to the pressure water source. Then the water valve of the pressure water source is opened, the pressure water source enters the water pipe, and the water valve at the water outlet end of the water pipe is controlled to be opened to realize water spraying.

A piston plate for controlling the communication or disconnection between the pressure water source and the valve port is axially and sealingly connected in the pipe, a transmission assembly is arranged between the piston plate and the rear end of the connecting rod, and when the connecting rod rotates, the transmission assembly controls the piston plate to slide along the axial direction of the pipe. A locking assembly is arranged in the disc body, and the locking assembly is used to lock the disc body in the box body.

[0006] Further technical solutions, when the locking assembly locks the disc body in the box body, the annular groove is in the box body, the annular groove is staggered with the valve port and located at the rear side of the valve port, the piston plate is located at the rear side of the valve port, and the pressure water source in the pipeline cannot enter the valve port; when the locking assembly unlocks the disc body, the pressure water source in the pipeline acts on the rear side of the piston plate to push the piston plate to move forward, the piston plate drives the connecting rod and the disc body to move forward through the transmission assembly, when the radial convex plate abuts against the plug, the disc body moves to the front end position, the annular groove completely extends out of the box body, the annular groove is communicated with the valve port, the piston plate is located at the rear side of the valve port, and the pressure water source in the pipeline cannot enter the valve port, at this time, the water pipe wound in the annular groove is pulled to drive the disc body to rotate, the disc body drives the connecting rod to rotate, the connecting rod drives the piston plate to move forward through the transmission assembly, when the water pipe is completely pulled out of the annular groove, the piston plate moves forward to the front side of the valve port, and the pressure water source in the pipeline enters the water pipe through the valve port, the annular groove and the water outlet hole.

[0007] Further technical solutions, the transmission assembly comprises a transmission screw rod, the transmission screw rod is fixed at the rear end of the connecting rod and arranged along the axial direction of the connecting rod; the piston plate is in threaded sealing connection with the transmission screw rod; a plurality of rearward extending limiting slide rods are fixed at the rear side of the plug, and the piston plate is in sliding connection with the limiting slide rods in the front-rear direction; when the connecting rod drives the transmission screw rod to rotate, the transmission screw rod drives the piston plate to move along the axial direction of the limiting slide rods.

[0008] Further technical solutions, the locking assembly comprises a threaded rod, a filter plate is fixedly installed between the rear ends of the limiting slide rods in the pipeline, the circumferential outer side of the filter plate is in contact with the inner side wall of the pipeline; the piston plate is located between the filter plate and the radial convex plate; the threaded rod penetrates through the connecting rod and the transmission screw rod in the axial direction of the connecting rod and is in threaded connection with the connecting rod and the transmission screw rod, a threaded hole is arranged at the central position of the filter plate, the rear end of the threaded rod is in threaded connection with the threaded hole when the locking assembly locks the disc body in the box body, and the rear end of the threaded rod is separated from the threaded hole when the locking assembly unlocks the disc body.

[0013] The water pipe reel has the beneficial effects that:

[0014] When the water pipe reel is used, the disc body does not need to be taken out from the box body by manpower, and only needs to be unlocked by rotating the threaded rod. At this time, the pressure water source acts on the piston plate to push the disc body to stretch out of the box body. When the radial convex plate abuts against the plug, the disc body moves to the front end position, the annular groove completely stretches out of the box body, the ring cutting groove is communicated with the valve port, and the piston plate is located at the rear side of the valve port, so that the pressure water source in the pipeline cannot enter the valve port. At this time, the water pipe wound in the annular groove is not disturbed by the box body, and the water pipe is driven to rotate the disc body when being pulled. The disc body drives the connecting rod to rotate, and the connecting rod drives the piston plate to move forward through the transmission screw rod. When the water pipe is completely pulled out of the annular groove, the piston plate moves forward to the front side of the valve port, and the pressure water source in the pipeline enters the water pipe through the valve port, the ring cutting groove and the water outlet hole. The piston plate not only pushes the disc body to move forward, but also controls the valve port to be communicated with or disconnected from the pressure water source. The connecting rod not only supports the disc body to rotate, but also drives the transmission screw rod to rotate. When the use is completed, the disc body is rotated in the reverse direction to wind the water pipe in the annular groove. At this time, the disc body drives the transmission screw rod to rotate through the connecting rod, and the transmission screw rod drives the piston plate to move backward to control the valve port to be disconnected from the pressure water source. When the water pipe is completely wound in the annular groove, the disc body is pushed into the box body, and the threaded rod is rotated to make the rear end of the threaded rod screw into the threaded hole, so that the disc body is locked in the box body. At the same time, the ring cutting groove is completely deviated from the valve port and located at the rear side of the valve port, so that the pressure water source is effectively prevented from entering the water outlet hole.

[0015] In addition, the rubber block can prevent the disc body from rotating when being locked in the box body. The convex block can facilitate driving the rotating disc to rotate. The one-way valve can prevent the water in the water outlet hole from flowing back to the ring cutting groove. The filter plate can remove impurities in the water and be used for connecting the threaded rod to lock the disc body in the box body. BRIEF DESCRIPTION OF DRAWINGS
