Description

Technical Field

[0001] This utility model relates to the field of high-pressure spray gun technology, and in particular to a folding multi-angle cleaning spray gun device. Background Technology

[0002] A cleaning spray gun is a tool that uses pressurized water flow to rinse the surface of an object. It is usually used in conjunction with a high-pressure water pump or cleaning machine. The high-pressure water is guided to the nozzle through a water channel inside, forming a concentrated water column or fan-shaped water curtain at the nozzle. It is used to remove oil, dust, dirt and other deposits. Cleaning spray guns are widely used in equipment maintenance, car washing, factory production lines, internal mechanical passages, aviation parts, pipelines and channels and other scenarios. It is a commonly used cleaning device with simple structure, convenient operation and high cleaning efficiency.

[0003] However, most existing cleaning spray guns have a fixed gun body structure, and the spray angle can only be changed by the operator's wrist posture. This makes it impossible to maintain stability under high pressure reaction force, which causes the nozzle direction to easily deviate, making it difficult to continuously and accurately clean the target position. In order to adapt to the cleaning needs of different angles, some spray guns use a single rotating joint, but it usually achieves angle switching through a threaded knob or friction locking method. This is not only cumbersome and time-consuming to adjust, but also prone to loosening and angle drift under the impact of high pressure water flow. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a folding multi-angle cleaning spray gun device.

[0019] In one embodiment, the folding multi-angle cleaning spray gun device includes: a first folding arm 100, a second folding arm 110, and a third folding arm 120, with a spray gun 200 disposed on one side of the third folding arm 120; a multi-angle adjustment mechanism 300 for quickly adjusting the unfolding angle of the multiple folding arms, the multi-angle adjustment mechanism 300 being disposed between the first folding arm 100, the second folding arm 110, and the third folding arm 120; wherein, the multi-angle adjustment mechanism 300 is disposed on a connecting shaft 310 between the first folding arm 100, the second folding arm 110, and the third folding arm 120, and an adjustment component 320 is disposed on the outer side of each of the multiple connecting shafts 310; a telescopic component 330 is disposed between the third folding arm 120 and the spray gun 200; and adjacent sides of the first folding arm 100, the second folding arm 110, and the third folding arm 120 are connected by corresponding connecting shafts 310.

[0020] In this embodiment, an adjustment component 320 is provided on the connecting shaft 310 between the first folding arm 100, the second folding arm 110, and the third folding arm 120, enabling rapid, intuitive, and stable adjustment of the angles between the folding arms. The adjustment component 320 can achieve rapid positioning and reliable locking between different angular positions, avoiding the problems of easy loosening and cumbersome adjustment of traditional spiral knobs. This allows operators to quickly adjust the nozzle direction in complex cleaning environments, thereby significantly improving the efficiency and accuracy of multi-angle cleaning. At the same time, the telescopic component 330 provided between the third folding arm 120 and the spray gun 200 allows the spray gun 200 to be extended and retracted according to the cleaning distance requirements, adapting to target positions at different depths and distances. It should be noted that the existing cleaning spray gun 200 typically includes a spray gun 200 body, a water inlet interface connected to a high-pressure water source, an internal high-pressure water flow channel, a trigger or valve structure for controlling the water flow switch, and a nozzle assembly located at the front end. The nozzle assembly can be replaced with different types of nozzles according to cleaning needs to achieve various spraying methods such as direct jet, fan-shaped, and rotating sprays. It is a basic functional component of the cleaning spray gun 200. The adjustment component 320 and the telescopic component 330 are both arranged on the folding arm structure and are independently distributed from the main structure and water channel of the existing spray gun 200. The adjustment component 320 is only used to change the relative angle between the folding arms and does not come into contact with the high-pressure water channel inside the spray gun 200. It will not affect the water flow guidance, pressure output and spraying state of the spray gun 200. The telescopic component 330 is set between the third folding arm 120 and the spray gun 200 and is used to adjust the relative distance between the spray gun 200 and the folding arm assembly. Its function is external mechanical extension and contraction and does not participate in the water flow transportation inside the spray gun 200. Therefore, it will not change the existing water pressure performance, spraying mode or on / off control structure of the spray gun 200.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, the adjustment assembly 320 includes a butterfly spring 321 and a positioning pin 322 fixedly installed on both sides of the connecting shaft 310. The other side of the butterfly spring 321 is fixedly connected to the adjacent folding arm. A first spring 323 is fixedly installed on the other side of the positioning pin 322. The other side of the first spring 323 away from the butterfly spring 321 is fixedly connected to the adjacent folding arm. A scale ring 324 is fixedly installed on the other side of the positioning pin 322. Magnets 325 are fixedly installed on the adjacent sides of the first folding arm 100, the second folding arm 110 and the third folding arm 120.

[0022] In this embodiment, by providing butterfly springs 321 on both sides of the connecting shaft 310, the folding arm can generate a stable preload when adjusting the angle. When the operator changes the angle of the folding arm, the disc spring 321 provides continuous damping and rebound force to the folding arm in the compressed or released state, thereby preventing the folding arm from suddenly loosening or jumping, making the angle adjustment process smoother, and maintaining its basic position before being fully locked, without dislodging due to its own weight or reaction force. The cooperation between the positioning pin 322 and the first spring 323 allows the positioning pin 322 to be quickly inserted and automatically returned to its original position between different positioning holes of the disc spring 321. When the folding arm angle is adjusted to the corresponding scale position of the scale ring 324, the positioning pin 322 automatically springs into the hole under the elastic force of the first spring 323, achieving instant locking. The operation does not require repeated turning, greatly improving the efficiency of angle adjustment. The magnets 325 set on the adjacent sides of the first folding arm 100, the second folding arm 110 and the third folding arm 120 can attract each other when the folding arms are stored, so that the folding arms can automatically close together to maintain a compact structure and prevent shaking or scattering during carrying or storage.

[0023] The positioning pin 322 is designed in the shape of a ring, and multiple protrusions that are adapted to the opening of the disc spring 321 are integrally connected to the side of the positioning pin 322 near the disc spring 321.

[0024] In this embodiment, the positioning pin 322 adopts a circular structure, so that the positioning pin 322 body forms a circumferential covering effect on the periphery of the connecting shaft 310. Multiple protrusions integrated on the side of the positioning pin 322 near the butterfly spring 321 can be adapted to the openings on the butterfly spring 321 respectively, so that the protrusions can be accurately embedded in the openings when rotated to the corresponding angle position, forming a reliable angle positioning.

[0025] A connecting seat 326 is provided on the outer side of the spray gun 200, and an mounting ring 327 is fixedly installed on the surface of the connecting seat 326. One side of the spray gun 200 is engaged with the mounting ring 327.

[0026] In this embodiment, the mounting ring 327 securely fixes the spray gun 200 to the connecting seat 326 through a snap-fit ​​structure, which not only facilitates the quick installation and removal of the spray gun 200, but also avoids problems such as nozzle shaking and displacement caused by loose threaded connections or flexible joints.

[0027] Two fixing tubes 328 are fixedly installed on the surface of the mounting ring 327. The interior of each fixing tube 328 is slidably connected with a pin 329. A second spring 3210 is sleeved through the surface of the pin 329. The other end of the second spring 3210 is fixedly connected to the inner wall of the fixing tube 328. The adjacent ends of the two pins 329 are locked and clamped to the spray gun 200.

[0028] In this embodiment, the spray gun 200 can be more reliably clamped and fixed through the double-sided limiting structure. The second spring 3210 sleeved on the outside of the pin 329 provides a continuous inward pushing force when the device is in standby mode, so that the pin 329 automatically extends to the limiting position and is stably clamped at the end adjacent to the spray gun 200. Thus, the automatic positioning and fixing of the spray gun 200 can be completed without additional operation.

[0029] The adjacent ends of the two pins 329 are both set in the shape of a frustum, and the ends of the two pins 329 that are far apart extend out to the corresponding fixing tubes 328.

[0030] In this embodiment, the adjacent ends of the two pins 329 are both frustum-shaped, so that the pins 329 can form a smooth guide surface when they contact the locking recess of the spray gun 200. When installing the spray gun 200, it is only necessary to push the spray gun 200 towards the mounting ring 327. The frustum-shaped pins 329 will be automatically pressed into the fixed tube 328 under the wedge-shaped guide, avoiding the problem of jamming or difficulty in alignment, and realizing the rapid positioning and natural alignment of the spray gun 200.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the telescopic assembly 330 includes a telescopic sleeve 331 fixedly installed between the connecting seat 326 and the third folding arm 120, and a threaded tube 332 and a screw 333 are respectively provided between the connecting seat 326 and the third folding arm 120.

[0032] In this embodiment, by providing a telescopic sleeve 331 between the connecting seat 326 and the third folding arm 120, and configuring a threaded tube 332 and a screw 333 respectively, the spray gun 200 can further achieve fine telescopic adjustment in the front and rear directions on the basis of multi-angle adjustment.

[0033] The threaded tube 332 is fixedly connected to the third folding arm 120, and the screw 333 is rotatably connected to the connecting seat 326. One end of the screw 333 extends into the threaded tube 332 and is threadedly connected to the threaded tube 332.

[0034] In this embodiment, when the screw 333 is rotated, one end of it extends into the threaded tube 332 and engages with the threaded tube 332, thereby driving the connecting seat 326 to move back and forth along the thread direction, so that the distance between the spray gun 200 and the third folding arm 120 can be continuously adjusted.

[0035] Working Principle: When using the folding multi-angle cleaning spray gun 200, the operator first unfolds the first folding arm 100, the second folding arm 110, and the third folding arm 120 according to the spatial environment of the cleaning site. Adjustment components 320 are provided on the outer side of the connecting shaft 310 between the folding arms. During adjustment, the operator only needs to hold the folding arm and change its relative angle to compress or release the disc spring 321. As the folding arm angle changes, the positioning pin 322 automatically enters the corresponding positioning hole of the scale ring 324 under the elastic force of the first spring 323, achieving rapid locking of the folding arm angle. The adjustment process requires no twisting or additional locking action. The folding arms can quickly switch between multiple angle positions to adapt to different cleaning directions. When the folding arms are folded for storage, the magnets 325 on the adjacent sides of each folding arm attract each other, keeping the folding arms compact and easy to carry and store. Then, the spray gun 200 is... The spray gun 200 is installed on the connecting seat 326 at the front end of the third folding arm 120. The operator only needs to push the spray gun 200 into the mounting ring 327. Under the action of the frustum-shaped guide surfaces of the two pins 329, the pins 329 are pressed into the fixed tube 328. When the spray gun 200 reaches the predetermined position, the pins 329 automatically rebound under the elastic force of the second spring 3210 and embed into the limiting recess of the spray gun 200, achieving quick locking. This structure makes the installation of the spray gun 200 tool-free and ensures that it will not loosen during high-pressure cleaning. For scenarios where the front and rear distance of the spray gun 200 needs to be adjusted, the operator can rotate the screw 333 in the telescopic component 330. The screw 333 is rotatably connected to the connecting seat 326 and engages with the threaded tube 332 when rotating, causing the connecting seat 326 to move back and forth along the axial direction, thereby realizing continuous adjustment of the telescopic position of the spray gun 200 and facilitating the operator to accurately position the spray distance.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
