Description

Technical Field

[0001] This utility model relates to the technical field of high-pressure cleaning spray accessories, specifically a high-pressure cleaning spray gun probe holder suitable for narrow spaces. Background Technology

[0002] As the core component of high-pressure cleaning equipment, the high-pressure cleaning spray gun removes stains by leveraging the powerful impact of high-pressure water flow. The foundation for using a high-pressure cleaning spray gun lies in understanding its technical principles. Its core is to convert the hydraulic / pneumatic energy of the equipment into the kinetic energy of the water flow through pressure conversion, forming a jet with strong peeling ability.

[0003] A related technology (publication number: CN202263697U) discloses a spray gun extension handle. The disclosed technical solution includes a spray gun fixing device, a telescopic rod, a handle bracket, a wrench, a pull rope, and a fixing connecting seat. The fixing connecting seat is located between the telescopic rod and the spray gun fixing device and is angularly connected to the spray gun fixing device. This utility model not only effectively extends the spray gun but also effectively adjusts the spray gun angle, ensuring the nozzle angle is approximately perpendicular to the surface being sprayed, thus improving the spraying effect at long distances or higher positions.

[0004] The aforementioned disclosed technical solutions reveal the following problems: Traditional high-pressure cleaning spray guns are mostly straight rods or have a fixed angle structure with fixed length and width, making them unsuitable for gaps less than 10cm wide or holes greater than 50cm deep. Even if they are forced to fit, it is difficult to adjust the nozzle angle, resulting in dirt in deep spaces and corners not being covered by the high-pressure water flow, creating cleaning dead zones with a cleaning coverage rate of less than 60%. To adapt to cleaning work in narrow spaces, we propose a high-pressure cleaning spray gun extension frame suitable for narrow spaces.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of operating in confined spaces in the aforementioned prior art, this utility model provides a high-pressure cleaning spray gun probe frame suitable for confined spaces. The probe frame structure combined with a multi-directional spray structure achieves an all-around cleaning effect. Its specific technical solution is as follows: A high-pressure cleaning spray gun probe holder suitable for confined spaces includes a spray gun holder, a locking member for securing the spray gun on the spray gun holder, a slidable multi-angle sealing nozzle at the front end of the spray gun holder, a probe assembly at the rear side of the spray gun holder, a handle at the movable end of the probe assembly, a reset-type press-start component at the top of the handle, and a pusher for pulling the spray gun trigger slidably on the spray gun holder, the pusher being started and stopped by the reset-type press-start component.

[0007] In the above technical solution, a bracket is fixedly connected to the corner of the spray gun frame, an electric push rod is fixedly connected to the inner wall of the bracket, and the pusher is fixedly connected to the movable end of the electric push rod.

[0008] The reset-type press-activated component includes a base fixed to the top of the grip, an activation cap embedded in the top of the base, and the activation cap being connected to the inner wall of the base by an elastic element. A movable contact that is electrically connected to an external power source is fixed to the bottom of the activation cap, and a fixed contact corresponding to the movable contact is fixed to the inner wall of the base. The fixed contact is electrically connected to the electric push rod.

[0009] The probe assembly includes a support frame fixed to the rear side of the spray gun frame. A lead screw is rotatably mounted inside the support frame, and the handle is threaded to the outside of the lead screw and sleeved on the outside of the support frame.

[0010] The locking component includes supports fixed to both sides of the spray gun frame, with a locking clamp extending through the inner cavity of the support, and fasteners extending into the inner cavity are threadedly connected to the outer wall of the support.

[0011] The spray gun holder has base columns on both sides of its outer wall, and a sliding support frame is sleeved on the outer wall of the base column. The sliding support frame and the base column are connected by an elastic element.

[0012] A sealing ring is fixedly connected to the opening of the multi-angle sealing sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The probe assembly drives the lead screw to rotate via a motor, causing the handle and spray gun holder to move relative to each other. This allows the spray gun holder to penetrate into narrow holes or crevices with a depth greater than 1m. The four-bar guide structure of the support frame ensures that the spray gun holder moves without deviation, avoiding collisions with the inner walls of the space. It is suitable for narrow spaces with a width of 5-10cm, increasing the cleaning coverage to 95% and completely eliminating cleaning dead spots such as corners and deep areas.

[0014] 2. The sliding multi-angle sealing sleeve at the horizontal front end of the gun holder can be flexibly adjusted in position. When installing the spray gun, it can be moved forward to leave space, and after installation, it can be reset to cover the nozzle. It is compatible with high-pressure spray guns of different lengths and diameters, and has strong versatility. There is no need to customize a special spray gun for narrow spaces. The spray holes of the multi-angle sealing sleeve are evenly distributed, which can transform the direct water flow of the spray gun into a directional diffusion water flow (such as fan shape or ring shape), expand the cleaning coverage area of ​​a single cleaning, and ensure the cleaning area in narrow spaces.

[0015] 3. The starter cap is reset by the elastic element. When pressed, the moving contact contacts the fixed contact to start the electric push rod. When released, the elastic element drives the starter cap to reset, the contact breaks and the operation stops. This forms an instant control of "press to start, release to stop", which is especially suitable for "point-shot cleaning" in narrow spaces (such as local impact of stubborn dirt), and significantly improves the flexibility of operation.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0019] A high-pressure cleaning spray gun probe holder suitable for confined spaces includes a spray gun holder 1. The spray gun holder 1 is equipped with locking components for securing the spray gun. The spray gun holder 1 has an L-shaped frame corresponding to the spray gun. Grooves for placing the spray gun are formed on the top and sides of the spray gun holder 1. A through slot is formed at the corner of the L-shaped spray gun holder 1, providing space for the spray gun trigger. A positionable multi-angle sealing nozzle 2 is slidably mounted on the front end of the spray gun holder 1. A through hole is formed on the inner wall of the frontmost part of the spray gun holder 1. A sliding frame slides against the inner wall of the through hole. The top end of the sliding frame is fixed to the bottom of the outer wall of the multi-angle sealing nozzle 2, and the bottom end of the sliding frame is fixed to the top of a limiting plate that fits against the bottom of the spray gun holder 1. A locking bolt is threaded onto the limiting plate. By adjusting the position of the multi-angle sealing nozzle 2, the installation of the spray gun becomes more convenient.

[0020] A probe assembly is provided on the rear side of the spray gun holder 1, and a handle 3 is provided on the movable end of the probe assembly. When operating in a narrow hole, after grasping the handle 3, the spray gun holder 1 is moved by the probe assembly, which in turn moves the fixed spray gun. A reset-type press-start component is provided on the top of the handle 3, and a push component 4 for pulling the spray gun trigger is slidably provided on the spray gun holder 1, and the push component 4 is started and stopped by the reset-type press-start component.

[0021] First, move the multi-angle sealing nozzle 2 to the front end to leave enough space for the spray gun installation. Then, insert the spray gun along the groove on the spray gun holder 1 and fix it to the spray gun holder 1 using the locking mechanism. Next, move the multi-angle sealing nozzle 2 towards the nozzle of the spray gun and fit the sealing ring 17 of the multi-angle sealing nozzle 2 onto the nozzle of the spray gun. Then, tighten the bolts on the bottom limit plate where the multi-angle sealing nozzle 2 is located to lock the position of the multi-angle sealing nozzle 2. After that, hold the handle 3 and drive the spray gun holder 1 to move through the extension assembly. After reaching the designated position, the reset-type press starter on the top of the handle 3 causes the pusher 4 to move, thereby driving the spray gun to spray. The water sprayed by the spray gun is sprayed sequentially through the evenly distributed nozzle holes on the multi-angle sealing nozzle 2 into the narrow space.

[0022] A bracket 5 is fixedly connected to the corner of the spray gun holder 1. The bracket 5 is fixed to the inner wall of the spray gun holder 1 at the pre-drilled opening of the spray gun trigger. An electric push rod 6 is fixedly connected to the inner wall of the bracket 5, and a pusher 4 is fixedly connected to the movable end of the electric push rod 6. The pusher 4 is arc-shaped, with its arc-shaped inner wall facing the spray gun trigger. A guide rod parallel to the electric push rod 6 is fixedly installed on the outer wall of the pusher 4, and the guide rod passes through the inner cavity of the bracket 5. By driving the electric push rod 6, the movable end of the electric push rod 6 moves the pusher 4 toward the spray gun trigger.

[0023] It is worth noting that the reset-type press-to-start component includes a base 7 fixedly attached to the top of the grip 3. An starter cap 8 is embedded in the top of the base 7, and the starter cap 8 is connected to the inner wall of the base 7 by an elastic element, which is a spring. The base 7 is fixed to the top of the grip 3, and a groove is opened in the top of the base 7. A slide rod that slides into the inner wall of the groove is fixedly installed at the bottom of the starter cap 8. The elastic elements are fixed to the bottom end of the slide rod and the bottom of the inner wall of the base 7, respectively.

[0024] The bottom of the starter cap 8 is fixedly connected to a moving contact 9 that is electrically connected to an external power source, and the inner wall of the base 7 is fixedly connected to a fixed contact 10 corresponding to the moving contact 9. The fixed contact 10 is electrically connected to the electric push rod 6. Both the fixed contact 10 and the moving contact 9 are metallic conductors. When the fixed contact 10 contacts the moving contact 9, the electric push rod 6 is connected to the power source, causing the movable end of the electric push rod 6 to push the spray gun trigger to move.

[0025] In addition, the probe assembly includes a support frame 11 fixed to the rear side of the spray gun holder 1. A lead screw 12 is rotatably mounted inside the support frame 11, and a handle 3 is threaded onto the outside of the lead screw 12, fitting snugly onto the outside of the support frame 11. The support frame 11 consists of four rods, all of which penetrate the inner cavity of the handle 3. A motor is fixed to the outer wall of the support frame 11 away from the spray gun holder 1 via a cover. The motor's output shaft is fixedly connected to one end of the lead screw 12, and the motor is connected to a power source via a wire. The two ends of the lead screw 12 rotate on the support frame 11 and the spray gun holder 1, respectively. The rotation of the lead screw 12 causes the support frame 11 to move the spray gun holder 1 and the handle 3 relative to each other.

[0026] The locking mechanism includes supports 13 fixed to both sides of the spray gun frame 1. A locking clamp 14 is provided through the inner cavity of each support 13, and fasteners extending into the inner cavity are threaded onto the outer wall of each support 13. Supports 13 are symmetrically fixedly installed on both sides of the outer wall of the horizontal frame of the spray gun frame 1. Each support 13 has a longitudinal through hole. Each locking clamp 14 is U-shaped, and both ends of each locking clamp 14 pass through the inner cavity of the support 13 at the same horizontal position. The fasteners are bolts. By adjusting the position of the locking clamps 14, the spray gun is fixed to the spray gun frame 1.

[0027] In addition, base columns 15 are provided on both sides of the outer wall of the spray gun holder 1, and a sliding support frame 16 is sleeved on the outer wall of the base columns 15. The sliding support frame 16 and the base columns 15 are connected by an elastic element. The elastic element can be a spring. The spring force makes the sliding support frame 16 fit against the inner wall of the narrow space. The side of the sliding support frame 16 away from the spray gun holder 1 is spherical. By supporting the inner wall of the narrow space, the stability of the spray gun holder 1 during movement is ensured.

[0028] Furthermore, a sealing ring 17 is fixedly connected to the opening of the multi-angle sealing sleeve 2. The sealing ring 17 is made of elastic material. After the nozzle of the spray gun passes through the sealing ring, the elastic deformation of the sealing ring 17 ensures the sealing of the nozzle of the spray gun inside the multi-angle sealing sleeve 2, preventing the sprayed water from spraying out from the opening of the multi-angle sealing sleeve 2.
