Description

Technical Field

[0001] This utility model relates to the field of spray technology, and in particular to a quick spray change device for a wheel washing machine. Background Technology

[0002] Wheel washing machines, also known as vehicle washing stations, are high-pressure, multi-directional washing devices designed to clean the tires and chassis of various engineering vehicles, based on the requirements of municipal, road administration, construction, environmental protection, and transportation departments. Existing wheel washing machines are designed with a main pipe running upwards along the side, with multiple sets of risers installed. Each set of risers has a certain number of nozzles installed, and the risers are connected to the main pipe using clamps. After a period of use, a large amount of silt and debris enters the water tank, causing nozzle blockage. Therefore, it is necessary to disassemble and replace the risers and main pipes connected to the nozzles. However, the current clamp connection between the risers and main pipes makes disassembly inconvenient, requires tools, and leads to the problem of tools being easily lost. Utility Model Content

[0003] The purpose of this invention is to solve the problems of existing technology where risers and main pipes are connected by clamps, resulting in inconvenient disassembly, the need for tools during disassembly, and the easy loss of these tools.

[0004] Therefore, in view of the aforementioned problem, this utility model proposes a quick-change spray device for a wheel washing machine, including a main pipe, an outlet in the middle of the main pipe, a step inside the main pipe, a slot fixedly installed on the side wall of the step, and a quick-release riser assembly installed inside the main pipe.

[0005] Preferably, the riser assembly includes: a riser outer cylinder, which is placed inside the step of the main pipe, and the riser outer cylinder has an aperture in the middle, which is consistent with the outlet. The lower side of the riser outer cylinder has multiple side grooves, and the side grooves are equipped with ball bearings. One side of the side groove has the same diameter as the ball bearing, and the other side has a smaller diameter than the ball bearing.

[0006] Preferably, the riser assembly further includes: a riser inner cylinder, and a second step is also provided inside the riser outer cylinder. The second step has an annular protrusion that slides up and down inside. The inner side of the annular protrusion is fixedly connected to the upper part of the riser inner cylinder. The width of the annular protrusion is the same as that of the second step. A spring is provided between the second step and the annular protrusion.

[0007] Preferred configuration: The inner cylinder of the riser has a connecting port in the middle, and a water pipe is fixedly connected to the upper outer side of the inner cylinder of the riser (not shown in the diagram). The inner cylinder of the riser has a groove on the outer side of the middle. Under normal conditions, when the spring is relaxed, it drives the inner cylinder of the riser to push upward, so that the groove is higher than the ball bearing at this time.

[0008] Beneficial effects: Hold the inner wall of the riser pipe with your hand, then press the inner pipe down. The spring will contract, and the inner pipe will sink. The ball bearing 4 will be guided from the inside of the side groove into the recess of the inner pipe pipe. Then, put the outer pipe pipe into the main pipe. At this time, release the inner pipe pipe, and the ball bearing will roll into the side groove. The part of the ball bearing that is outside the side groove will be locked into the slot, thus locking it in the main pipe, thereby realizing the quick replacement of the main pipe and the riser pipe.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1 to 3 A quick-change spray device for a wheel washing machine includes a main pipe 1, with an outlet 101 in the middle of the main pipe 1. A step 102 is provided inside the main pipe 1, and a slot 103 is fixedly installed on the side wall of the step 102. A quick-release riser assembly is installed inside the main pipe 1. When the outer cylinder 2 of the riser is placed into the main pipe 1, the inner cylinder 3 of the riser is released. The spring of the inner cylinder 3 relaxes and drives the recess 302 to move upward. At this time, the ball bearing 4 will roll into the side groove 202, and the ball bearing 4 will be embedded in the slot 103 on the side of the side groove 202, thereby locking it in the main pipe 1.

[0015] Preferably, the riser assembly includes: a riser outer cylinder 2, which is placed inside the step 102 of the main pipe 1. The riser outer cylinder 2 has an aperture in the middle, which is consistent with the outlet 101. The lower side of the riser outer cylinder 1 has multiple side grooves 202, and ball bearings 4 are provided inside the side grooves 202. One side of the side groove 202 has the same diameter as the ball bearings 4, and the other side has a smaller diameter than the ball bearings 4. The side grooves 202 have a certain slope. The riser inner cylinder 3 and the riser outer cylinder 2 also have a step 201 inside. The step 201 has an annular protrusion 304 that slides up and down inside. The annular protrusion 304 is fixedly connected to the upper part of the inner cylinder 3 of the riser. The width of the annular protrusion 304 is the same as that of the second step 201. A spring 303 is provided between the second step 201 and the annular protrusion 304, which is held on the side wall of the inner cylinder 3 of the riser. Then, the inner cylinder 3 of the riser is pressed down. At this time, the pressure of the inner cylinder 3 of the riser will cause the spring 303 to contract. Then the inner cylinder 3 of the riser sinks, and the recess 302 of the inner cylinder 3 of the riser will be connected with the side groove 202. Then the ball 4 will be guided from the inside of the side groove 202 into the recess 302 of the inner cylinder 3 of the riser.

[0016] Preferably, the inner cylinder 3 of the riser has a connecting port 301 in the middle, and a water pipe is fixedly connected to the upper outer side of the inner cylinder 3 (not shown in the figure). The inner cylinder 3 of the riser has a groove 302 in the middle outer side. In the normal state, when the spring 303 is relaxed, it drives the inner cylinder 3 of the riser to push upward, so that the groove 302 is higher than the ball 4 at this time.

[0017] Working principle:

[0018] In use, the operator presses their hand on the upper part of the connection port 301 or holds it on the side wall of the inner cylinder 3 of the riser pipe, and then presses the inner cylinder 3 of the riser pipe down. At this time, the pressing of the inner cylinder 3 of the riser pipe will cause the spring 303 to contract. Then the inner cylinder 3 of the riser pipe sinks down, and the recess 302 of the inner cylinder 3 of the riser pipe will connect with the side groove 202. Then the ball bearing 4 will be guided from the inside of the side groove 202 into the recess 302 of the inner cylinder 3 of the riser pipe. Then the outer cylinder 2 of the riser pipe is placed into the main pipe 1. At this time, the inner cylinder 3 of the riser pipe is released, and the spring of the inner cylinder 3 of the riser pipe relaxes, which will cause the recess 302 to move upward. At this time, the ball bearing 4 will roll into the side groove 202, and the side of the ball bearing 4 that is outside the side groove 202 will be locked into the slot 103, thereby locking it in the main pipe 1, thus realizing the quick replacement of the main pipe and the riser pipe.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
