Description

Technical Field

[0001] This utility model belongs to the technical field of high-pressure washer spray gun connection, and in particular relates to an easy-to-replace high-pressure washer spray gun. Background Technology

[0002] A high-pressure washer spray gun is a tool used for high-pressure cleaning operations. It has a wide range of applications and is used in conjunction with a high-pressure washer to spray high-pressure water in a specific manner. The high-pressure washer uses an electric motor or fuel engine to drive a water pump, pressurizing ordinary water to a high-pressure state, and then spraying the high-pressure water jet through the spray gun. The impact force of the water jet is used to remove dirt, oil stains, mold, etc.

[0003] In high-pressure cleaners, the choice of spray gun directly affects the cleaning effect and efficiency. Therefore, different cleaning tasks require different spray guns. Most high-pressure cleaner spray guns are bolted, so an easy-to-replace high-pressure cleaner spray gun is needed. This can be achieved by connecting the pipe ends and then using the rebound force of the coil spring to drive the L-shaped hook rod to engage, thus allowing for quick replacement of the high-pressure cleaner spray gun. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-replace high-pressure washer spray gun, which allows for quick replacement of the high-pressure washer spray gun by connecting the pipe ends and then using the rebound force of the coil spring to drive the L-shaped hook rod to engage, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high-pressure washer spray gun that is easy to replace includes a pipeline end one, a pipeline end two is provided at the left end of the pipeline end one, a spray gun is fixedly connected to the left end of the pipeline end two, a sealing ring is pasted on the surface of the pipeline end one, a fixing ring is fixedly connected to the surface of the pipeline end one, two hook rods one are fixedly connected to the left side of the fixing ring, a first limiting groove is opened on the inner wall of each of the two hook rods one, an annular groove matching the sealing ring is opened on the inner wall of the pipeline end two, an annular block is rotatably connected to the surface of the pipeline end two, a coil spring is fixedly connected between the inner wall of the annular block and the pipeline end two, two hook rods two are fixedly connected to the right side of the annular block, and a fixing block is integrally formed on the surface of the two hook rods two.

[0006] Preferably, the left end of the first pipe end extends into the inner cavity of the second pipe end.

[0007] Preferably, the surface of the ring block is fixedly connected with two symmetrically arranged second limiting grooves, and the surface of the second pipe end is provided with a rotating ring that matches the second limiting grooves.

[0008] Preferably, the first limiting groove engages with the fixing block.

[0009] Preferably, both hook rod one and hook rod two have wedge-shaped surfaces.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a rotating ring block to drive the deformation of a coil spring, and then moves the first end of the pipeline to the inner cavity of the second end of the pipeline. At this time, the ring block is released, and the rebound force of the coil spring drives the ring block to rotate, thereby causing the ring block to drive the second hook rod to engage with the first hook rod, thus achieving the purpose of quickly replacing the spray gun of the high-pressure washer.

[0012] 2. This utility model uses the combination of the rotating ring and the second limiting groove to limit the rotation of the ring block on the two surfaces of the pipeline end, thereby preventing the ring block from shaking during rotation and improving the stability of the ring block during rotation.

[0013] 3. By setting the wedge-shaped surface, the surfaces of hook rod one and hook rod two are treated with a slope, so that hook rod one and hook rod two will squeeze each other when hooked, making hook rod one and hook rod two easier to hook. Attached Figure Description

[0021] In the following description, embodiments of the easily replaceable high-pressure washer spray gun of the present invention will be described with reference to the accompanying drawings. Example

[0022] Figure 1-4 This invention illustrates an easily replaceable high-pressure washer spray gun according to an embodiment of the present invention. It includes: a pipe end 1; a pipe end 2 at the left end of the pipe end 1; a spray gun 3 fixedly connected to the left end of the pipe end 2; a sealing ring 4 affixed to the surface of the pipe end 1; a fixing ring 5 fixedly connected to the surface of the pipe end 1; two hook rods 6 fixedly connected to the left side of the fixing ring 5; each hook rod 6 has a first limiting groove 7 on its inner wall; an annular groove 8 matching the sealing ring 4 is formed on the inner wall of the pipe end 2; and an annular block 9 rotatably connected to the surface of the pipe end 2; the inner wall of the annular block 9 is positioned between the pipe end 2 and the pipe end 2. A coil spring 10 is fixedly connected to the ring block 9. Two symmetrically arranged second limiting grooves 12 are fixedly connected to the surface of the ring block 9. A rotating ring 11 matching the second limiting groove 12 is opened on the surface of the pipe end 2. By cooperating with the second limiting groove 12, the rotation of the ring block 9 on the surface of the pipe end 2 is limited, avoiding the ring block 9 from shaking during rotation, thereby improving the stability of the ring block 9 during rotation. Two hook rods 13 are fixedly connected to the right side of the ring block 9. A fixing block 14 is integrally formed on the surface of the two hook rods 13. The first limiting groove 7 is engaged with the fixing block 14. Example

[0023] Figure 1-4 This invention illustrates an easily replaceable high-pressure washer spray gun according to an embodiment of the present invention. It includes: a pipe end 1; a second pipe end 2 located at the left end of the first pipe end 1; the left end of the first pipe end 1 extending into the inner cavity of the second pipe end 2; a spray gun 3 fixedly connected to the left end of the second pipe end 2; a sealing ring 4 adhered to the surface of the first pipe end 1; a fixing ring 5 fixedly connected to the surface of the first pipe end 1; two hook rods 6 fixedly connected to the left side of the fixing ring 5; a first limiting groove 7 formed on the inner wall of each hook rod 6; and a groove on the inner wall of the second pipe end 2 that matches the sealing ring 4. The ring groove 8 is fitted with a ring block 9 rotatably connected to the surface of the pipe end 2. A coil spring 10 is fixedly connected between the inner wall of the ring block 9 and the pipe end 2. Two hook rods 13 are fixedly connected to the right side of the ring block 9. A fixing block 14 is integrally formed on the surface of the two hook rods 13. Both hook rod 6 and hook rod 13 have wedge-shaped surfaces 15. The wedge-shaped surfaces 15 allow the surfaces of hook rod 6 and hook rod 13 to be beveled, so that hook rod 6 and hook rod 13 will press against each other when hooked, making it easier to hook rod 6 and hook rod 13.

[0024] Working principle: When using this utility model, the user rotates the ring block 9, causing the ring block 9 to drive the coil spring 10 to deform. At this time, the pipe end 1 and the pipe end 2 are connected, so that the sealing ring 4 fits into the ring groove 8. Then, the ring block 9 is released, and under the action of the spring 10's rebound force, the spring 10 drives the ring block 9 to rotate, so that the ring block 9 drives the hook rod 2 13 to hook rod 1 6 to hook each other. The setting of the first limiting groove 7 and the fixing block 14 limits the movement between hook rod 1 6 and hook rod 2 13, preventing hook rod 1 6 and hook rod 2 13 from shaking and slipping, thereby improving the connection efficiency of the high-pressure washer spray gun.

[0025] In summary, this easily replaceable high-pressure washer spray gun achieves its purpose of quickly replacing the high-pressure washer spray gun by rotating the ring block 9 to deform the coil spring 10, then moving the pipe end 1 to the inner cavity of the pipe end 2. At this time, the ring block 9 is released, and the rebound force of the coil spring 10 causes the ring block 9 to rotate, thereby causing the ring block 9 to engage with the hook rod 13 and the hook rod 6.
