[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1: This embodiment Figure 1-Figure 4 As shown, in order to solve the problem that the existing spray hose joint is difficult to quickly connect, the working process of the spray hose connection structure with a quick connector is disclosed, and the effect that the spray hose can enable the joint to be quickly connected is achieved. The specific contents are as follows:

[0033] A hose body 1 and a nozzle base 2 fixedly mounted on the upper end of the hose body 1;

[0034] An adjustment area 3 is fixedly installed inside the nozzle base 2, and a docking joint 4 is slidably installed inside the upper end of the nozzle base 2;

[0035] A docking structure is provided on the outside of the nozzle base 2, and the docking structure can achieve the effect of quick docking of the joint through the snap-fit ​​principle;

[0036] The interior of the docking structure is provided with a mounting sleeve 5 and a buffer groove 6. The mounting sleeve 5 is sleeved on the outside of the nozzle base 2, and six groups of buffer grooves 6 are opened at equal angles inside the mounting sleeve 5. A support spring 8 is nested and installed inside the mounting sleeve 5, and the support spring 8 is located on the outside of the nozzle base 2.

[0037] The interior of the docking structure is provided with a limit groove 7 and a docking groove 9, the limit groove 7 is opened at an equal angle inside the nozzle base 2, and a limit ball 10 is slidably installed inside the limit groove 7, and the docking groove 9 is opened at an equal angle outside the docking head 4;

[0038] The buffer groove 6 , the limiting groove 7 and the docking groove 9 are arranged correspondingly, and both the buffer groove 6 and the docking groove 9 are engaged and connected with the limiting ball 10 .

[0039] When using the spray hose with a quick connector, first install the hose at the position where work is required. After the hose is installed, the docking joint 4 can be installed inside the upper end of the nozzle base 2. During this process, it is necessary to push the installation sleeve 5 downward first, and the support spring 8 will be squeezed and contracted during the movement of the installation sleeve 5, and the buffer groove 6 will move downward and maintain a horizontal state with the limit groove 7 during the movement of the installation sleeve 5. After that, the docking joint 4 can be moved downward inside the nozzle base 2, and the docking joint 4 will contact and lock the limit ball 10 during the downward movement. The limiting ball 10 is squeezed so that it moves toward the inside of the buffer groove 6 and engages with the buffer groove 6. After the docking joint 4 and the nozzle base 2 are docked, the installation sleeve 5 is released, and at this time, the docking groove 9 and the limiting groove 7 are in a horizontal state. Then the contracted support spring 8 will expand and push the installation sleeve 5 to move to the initial position. At this time, the buffer groove 6 will squeeze the limiting ball 10 and make the limiting ball 10 move from the inside of the limiting groove 7 to the inside of the docking groove 9. At this time, the limiting ball 10 will engage with the docking groove 9 and limit the docking joint 4 at this position, thereby completing the installation process of the joint, which effectively improves the convenience of installation of the lubricating pipe joint.

[0040] Embodiment 2: This embodiment is as follows Figure 1-Figure 7 As shown, in order to solve the problem that the existing spray hose joint is difficult to automatically pass the spray distance, the working process of the spray hose adjustment structure with a quick connector is disclosed, and the effect of facilitating the spray hose to change its spray distance is achieved. The specific contents are as follows:

[0041] An adjustment structure is provided inside the adjustment area 3, and the adjustment structure can achieve the effect of changing the spray distance of the nozzle through the meshing principle;

[0042] A fixed cylinder 11 and a moving gear cylinder 12 are arranged inside the adjustment structure. The fixed cylinder 11 is fixedly installed at the lower end of the docking head 4, and the moving gear cylinder 12 is slidably installed inside the fixed cylinder 11, and an adjustment spring 13 is fixedly installed at one end of the moving gear cylinder 12 close to the fixed cylinder 11;

[0043] A fixed ring 14 and a rotating rod 15 are arranged inside the adjustment structure. The fixed ring 14 is nested inside the adjustment area 3 , and the rotating rod 15 is equiangularly rotated inside the fixed ring 14 , and a rotating plate 17 is fixedly installed outside the rotating rod 15 .

[0044] When using the spray hose with a quick connector, it is necessary to control the spray distance according to the usage situation. In the process of changing the spray distance, it is necessary to change the pressure inside the butt joint 4. To change the pressure inside the butt joint 4, it is necessary to control the flow rate and amount of liquid entering the butt joint 4 from the adjustment area 3. At this time, it is necessary to change the amount of liquid passing through the fixing ring 14 at the same time to adjust the spray distance.

[0045] During this process, the joint 4 needs to be rotated, and the rotation of the joint 4 will cause the fixed cylinder 11 and the moving gear cylinder 12 to rotate, and the moving gear cylinder 12 will drive the rotating rod 15 to rotate through the adjusting gear 16 during the rotation, and the rotating rod 15 will drive the rotating plate 17 on its outer side to rotate synchronously during the rotation, and the rotating plate 17 will change the cross-sectional area of ​​the liquid passing through the fixed ring 14 during the rotation, thereby achieving the effect of changing the amount of liquid passing through the fixed ring 14 in the same time, and then adjusting the distance of the spray hose, thereby improving the convenience of using the spray hose joint.

[0046] Embodiment 3: This embodiment is as follows Figure 5-Figure 6 As shown, in order to solve the problem that the adjustment gear and the moving gear cylinder are difficult to directly mesh, a process of meshing the adjustment gear and the moving gear cylinder of a spray hose with a quick connector is disclosed, and the effect of quick adjustment of the spray hose is achieved. The specific contents are as follows:

[0047] An adjusting gear 16 is fixedly mounted on one end of the rotating rod 15 close to the fixing ring 14 , and a rotating groove 18 is formed at the upper end of the fixing ring 14 . The lower end of the moving gear cylinder 12 is located inside the rotating groove 18 , and the moving gear cylinder 12 is meshedly connected with the adjusting gear 16 .

[0048] In the process of adjusting the spray distance of the spray hose with a quick connector, it is necessary to make the moving gear cylinder 12 drive the adjusting gear 16 to rotate, and in the process of preliminary installation of the connector 4, it is difficult to ensure that the moving gear cylinder 12 is directly meshed with the adjusting gear 16. At this time, during the rotation of the connector 4, the adjusting spring 13 will be driven to rotate through the fixed cylinder 11, and the adjusting spring 13 is in a contracted state. During the rotation of the connector 4, the adjusting spring 13 will drive the moving gear cylinder 12 to rotate and squeeze the moving gear cylinder 12, and the moving gear cylinder 12 will mesh with the adjusting gear 16 during the rotation, thereby facilitating the change of the spray distance of the spray hose connector, further improving the convenience of adjustment of the spray hose connector, and increasing the overall practicality.

[0049] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
