Description

Technical Field

[0001] This utility model relates to the technical field of tool magazine door structure for high-pressure cleaners, specifically a tool magazine door structure for a high-pressure cleaner with a high-speed tool magazine. Background Technology

[0002] In the field of high-pressure washer technology, the compact design of the tool magazine structure is crucial for improving the space utilization of the work area. Since high-pressure cleaning operations typically require multiple steps to be completed within a limited space, minimizing the space occupied by the tool magazine and its drive mechanism while ensuring efficient opening and closing of the magazine door has always been a pressing technical challenge in this field.

[0003] Currently, existing technologies commonly employ a dual-cylinder drive system to achieve the left and right opening and closing of the tool magazine door, using two independently configured cylinders to control the opening and closing of the left and right doors respectively. However, this solution has significant drawbacks: the dual-cylinder layout requires additional air piping and mounting brackets, resulting in an increased overall structural volume and occupying a disproportionately large share of the workspace. Furthermore, the high-pressure cleaning environment contains large amounts of high-pressure water mist, abrasive dust, and chemically corrosive liquids. Traditional improved solutions using motor drives, due to the non-sealed structure of the motor itself (such as heat dissipation holes and shaft end clearances), are highly susceptible to short circuits or component corrosion due to liquid penetration, posing serious safety hazards and shortening equipment lifespan.

[0004] Therefore, existing technologies do not offer an optimized solution that can adapt to the harsh conditions of high-pressure cleaning while also enabling rapid opening and closing of the tool magazine door and maintaining a compact structure. Consequently, there is an urgent need in this field to develop a novel high-speed tool magazine door drive mechanism that, while ensuring environmental sealing, simplifies the structural layout through an innovative transmission mechanism, simultaneously improving the opening and closing efficiency of the tool magazine door and space utilization, thereby meeting the demands for efficient and intensive development of high-pressure cleaning equipment.

[0015] Preferably, the present invention further includes: the rack adjustment support includes a horizontally arranged eccentric adjustment shaft, and one or more support wheels are provided on the adjustment shaft, the one or more support wheels being used to support the bottom of the rack.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] Space-saving advantages: By innovatively adopting a single-cylinder driven rack and pinion transmission mechanism, the traditional dual-cylinder split layout is abandoned, effectively eliminating redundant air lines and bracket installation space. This significantly improves the layout adaptability of the tool magazine body and the working area, making it particularly suitable for the integration needs of high-pressure cleaning equipment in confined spaces.

[0018] Increased Efficiency Through Speed ​​Transmission: Based on the motion conversion principle of gear and rack meshing transmission, the linear extension and retraction motion of the cylinder piston rod is transformed into a bidirectional symmetrical opening and closing action of the door. This mechanism, through its split rack design and the constant-speed reverse transmission characteristics of the double-gear set, achieves synchronous action of both doors with a single stroke, making the door opening and closing speed twice that of the cylinder extension and retraction speed, resulting in a significant improvement in overall cleaning efficiency.

[0027] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figure 1-7 This utility model relates to a tool magazine door structure for a high-pressure washer with a double-speed tool magazine. Its core components include a tool magazine base 1, a left tool magazine door 2, a right tool magazine door 3, a front rack 5, a rear rack 27, a cylinder 6, a gear 7, a bearing seat 8, a rotating shaft 29, and a guide mechanism.

[0029] The tool magazine base 1 is an installation platform, with a movable left tool magazine door 2 and a right tool magazine door 3 on the left and right sides respectively. The tool magazine base 1 is equipped with a tool magazine, and the tool magazine is equipped with several tools with high-pressure cleaning nozzles.

[0030] A bearing housing 8 is fixedly mounted on the equipment base. A horizontally positioned bearing 28 is mounted on the bearing housing 8. The outer ring of the bearing 28 is mounted on the bearing housing 8, and a rotating shaft 29 is inserted into the inner ring of the bearing 28. Grooves are provided on the inner sides of both the inner and outer rings of the bearing 28, and several bearing rollers are disposed within these grooves. A protruding structure is provided in the middle of the rotating shaft 29. A gear 7 is fitted onto the upper part of the rotating shaft 29 and tightly engages with it, being supported by the upper top surface of the protruding structure. The lower bottom surface of the protruding structure mates with the upper top surface of the inner ring of the bearing 28. The protruding structure of the rotating shaft 29 separates the gear 7 and the bearing 28, enabling the bearing housing 8 to provide vertical support to the gear 7.

[0031] The bearing housing 8 is also provided with support frames 30 on the front and rear sides. A horizontally arranged rack adjustment support 23 is provided on the support frame 30, and a vertically arranged rack side guide plate 14 is provided on the rack adjustment support 23. A gap is left between the rack side guide plate 14 and the gear 7 in the middle of the bearing housing 8. The rack adjustment support 23 includes an adjustable handle and a horizontally arranged eccentric adjustment shaft 31 mounted on the adjustable handle. One or more support wheels 32 are provided on the eccentric adjustment shaft 31.

[0032] The front rack 5 and the rear rack 27 are fitted together on the rack adjustment support 23, at the gap between the rack side guide plate 14 and the gear 7. The tooth surface of the rack meshes with the gear 7, and the smooth surface fits against the rack side guide plate 14 to form a front-to-back upward clamping action on the front rack 5 and the rear rack 27.

[0033] With the above configuration, when any one of the components—the front rack 5, the rear rack 27, or the gear 7—moves, the entire assembly will move in tandem, resulting in the rotation of the gear 7 and the synchronous axial movement of the front rack 5 and the rear rack 27. Furthermore, the eccentric adjustment shaft 31 rotates by rotating the adjustment handle of the rack adjustment support 23. Because the eccentric adjustment shaft 31 is eccentrically positioned and its design is non-coaxial with the adjustment handle, it rotates around the central axis of the rack adjustment support 23. Since the rack adjustment support 23 is horizontally positioned, and its central axis is also horizontally positioned, the height of the eccentric adjustment shaft 31 will change periodically during its circular motion. This change allows adjustment of the height of the support wheel 32 on the eccentric adjustment shaft 31, and the front rack 5 or rear rack 27 supported by the support wheel 32 will also change in height, thus achieving alignment between the front rack 5 or rear rack 27 and the tooth surface of the gear 7.

[0034] The left guide shaft 4 and the right guide shaft 26 are coaxially arranged on both sides of the bearing seat 8, and both ends are fixed to the tool magazine base 1 through the guide shaft support 11.

[0035] The front rack 5 extends to the left and connects to the left tool magazine door 2 via the left door connecting plate 12, while the rear rack 27 extends to the right and connects to the right tool magazine door 3 via the right door connecting plate 13. The left door connecting plate 12 and the right door connecting plate 13 are L-shaped bent structures, which are fixed to the lower inner side of the left tool magazine door 2 and the right tool magazine door 3, respectively, and slide in cooperation with the guide shaft through the slider 24 to ensure smooth door movement.

[0036] Cylinder 6 is mounted on tool magazine base 1, and its telescopic end is connected to one end of rear rack 27 via floating joint 10. When cylinder 6 extends or retracts, it drives rear rack 27 to move horizontally. Gear 7 meshes with front rack 5 and rear rack 27 simultaneously, converting the linear motion of rear rack 27 into the rotational motion of gear 7, which in turn drives front rack 5 to move in the opposite direction, ultimately achieving the synchronous opening and closing of left tool magazine door 2 and right tool magazine door 3.

[0037] The upper guide rail 22 is fixed to the top of the tool magazine via the upper guide rail support 25. The upper rollers 21 on the inner side of the top of the left tool magazine door 2 and the right tool magazine door 3 roll in cooperation with the upper guide rail 22, further restricting the movement trajectory of the door and preventing deviation.

[0038] A left door sensor 17, a right door sensor 15, a second right door sensor 16, and a second left door sensor 18 are installed on both sides of the tool magazine base 1 to detect the opening and closing status of the doors. The cylinder buffer block 19 is located at the end of the extension and retraction path of the cylinder 6 to absorb the impact of the movement.

[0039] Cylinder 6 is a waterproof cylinder with a sealed structure, which is suitable for the humid environment of high-pressure cleaners.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
