Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning equipment technology, and specifically discloses a folding bracket for a portable high-pressure cleaner. Background Technology

[0002] Portable pressure washers are widely used in homes, businesses, and industries due to their ease of movement and use. To support the main unit and keep it away from water and dirt on the ground, they are usually equipped with a special stand. In the existing technology, this type of stent mainly has the following two drawbacks: With a fixed storage volume, portability is insufficient. Most existing stands adopt a simple hinged folding structure, and their volume and shape in the folded state are fixed and cannot be further compressed. This results in the stands still occupying a lot of space during transportation or storage, failing to fully utilize the mobility advantages of portable cleaning machines. The position adjustment function is limited and the flexibility of use is poor. Most brackets have limited height and angle adjustment ranges or require manual multi-step operations, making it impossible to quickly and flexibly adjust the main unit of the cleaning machine to the required optimal working position (such as avoiding obstacles or adapting to different cleaning angles) during use; this reduces the efficiency and convenience of cleaning operations. Therefore, there is an urgent need in this field for a bracket solution that can achieve more compact folding and has flexible multi-position adjustment capabilities. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4A folding stand for a portable high-pressure washer includes a base 1 and a folding mechanism. The folding mechanism is rotatably mounted on the top of the base 1 via a rotating mechanism. The folding mechanism includes a support arm 2, a sliding arm 3, a hinged arm 4, a first connecting arm 5, and a second connecting arm 6. The support arm 2 is vertically fixed to the rotating mechanism. The sliding arm 3 is slidably mounted on the support arm 2. One end of the hinged arm 4 is hinged to the bottom of the sliding arm 3. A second slider 7 is slidably mounted on the sliding arm 3. The second slider 7 is hinged to one end of the first connecting arm 5 and the second connecting arm 6, respectively. The other end of the first connecting arm 5 is hinged to the middle of the hinged arm 4. The other end of the second connecting arm 6 is slidably connected to the top of the hinged arm 4. The support arm 2 is provided with a first driving device 8 for driving the sliding arm 3 to slide, and the sliding arm 3 is provided with a second driving device 9 for driving the second slider 7 to slide.

[0024] In this embodiment: when the bracket needs to be adjusted, the first drive device 8 is activated, driving the sliding arm 3 to move up and down along the support arm 2, thereby adjusting the height of the main unit of the cleaning machine; simultaneously, the second drive device 9 is activated, driving the second slider 7 to slide along the sliding arm 3. The movement of the second slider 7 acts on the hinge arm 4 through the first connecting arm 5 and the second connecting arm 6. The first connecting arm 5 provides a constraint at the middle hinge point, and the second connecting arm 6 pushes the hinge arm 4 to rotate around its bottom hinge point through the sliding connection between its top end and the hinge arm 4, thereby adjusting the pitch angle of the main unit of the cleaning machine; in addition, when the horizontal direction of the cleaning machine needs to be adjusted, the drive mechanism can be activated; specifically, the motor 14 works, and after being reduced in speed and increased in torque by the worm gear reducer 15, it drives the rotating seat 12 to rotate in the rotating groove 10 through the bearing 11, thereby driving the entire folding mechanism and the cleaning machine above to rotate in the horizontal plane, thereby adjusting the horizontal orientation; the self-locking characteristic of the worm gear reducer 15 can also effectively prevent the bracket from rotating accidentally due to external force during operation, enhancing stability.

[0025] As a technical optimization of this utility model, the first driving device 8 and the second driving device 9 are electric telescopic rods, pneumatic telescopic rods, or hydraulic telescopic rods.

[0026] In this embodiment: different types of telescopic rods provide power for the sliding arm 3 and the second slider 7 to slide. Users can choose a suitable drive device according to factors such as actual use scenario, cost, and maintenance needs. For example, electric telescopic rods are easy to control and can achieve automated operation; pneumatic telescopic rods have a fast response speed; and hydraulic telescopic rods can provide greater driving force and are suitable for situations with high force requirements.

[0027] As a technical optimization of this utility model, the rotating mechanism includes a rotating groove 10 opened on the top of the base 1, a rotating seat 12 rotatably disposed in the rotating groove 10 via a bearing 11, and the lower end of the support arm 2 is fixedly connected to the top of the rotating seat 12.

[0028] In this embodiment, the support arm 2 can rotate flexibly relative to the base 1. When using a high-pressure washer, the orientation of the washer can be easily adjusted without moving the entire device, which increases the flexibility of the support and improves the convenience of the cleaning operation.

[0029] As a technical optimization of this utility model, the base 1 has an installation cavity 13, and the installation cavity 13 is provided with a drive mechanism for driving the rotating seat 12 to rotate.

[0030] In this embodiment, the drive mechanism provides the power source for the rotation of the rotating seat 12, eliminating the need for manual rotation of the rotating seat 12, thus achieving automated control, further improving the convenience of operation, and also enabling more precise control of the rotation angle.

[0031] As a technical optimization of this utility model, the drive mechanism includes a motor 14 and a worm gear reducer 15. The output end of the motor 14 is coaxially and fixedly connected to the input end of the worm gear reducer 15, and the output shaft of the worm gear reducer 15 is coaxially and fixedly connected to the rotating seat 12.

[0032] In this embodiment: the motor 14 provides the original power, and the worm gear reducer 15 uses its own speed reduction and torque increase characteristics to convert the high speed and low torque output of the motor 14 into a low speed and high torque output, thereby smoothly driving the rotating seat 12 to rotate, ensuring the stability and reliability of the rotation process, and at the same time meeting the needs of different speeds and torques.

[0033] As a technical optimization of this utility model, a first sliding groove 16 is provided on the support arm 2 along the height direction, and a first slider 17 adapted to the first sliding groove 16 is provided on the inner side of the sliding arm 3. The first driving device 8 is connected to the first slider 17 to drive the sliding arm 3 to slide along the support arm 2.

[0034] In this embodiment: the extension and retraction of the first driving device 8 drives the first slider 17 to slide in the first slide groove 16, thereby realizing the sliding arm 3 to slide up and down along the support arm 2, thereby adjusting the height of the bracket to meet the cleaning operation requirements at different heights.

[0035] As a technical optimization of this utility model, a second slide groove 18 is provided on the sliding arm 3 along the height direction, and the second slider 7 is slidably disposed in the second slide groove 18. The second driving device 9 is connected to the second slider 7 to drive the second slider 7 to slide along the sliding arm 3.

[0036] In this embodiment: when the second driving device 9 is working, it drives the second slider 7 to slide in the second slide groove 18, thereby realizing the position adjustment of the first connecting arm 5 and the second connecting arm 6 that are hinged to the second slider 7, further changing the state of the hinge arm 4, and realizing more flexible angle and position adjustment of the bracket.

[0037] As a technical optimization of this utility model, a third sliding groove 19 is provided on the hinged arm 4 along the length direction, and a third slider 20 is slidably arranged in the third sliding groove 19. The other end of the second connecting arm 6 is hinged to the third slider 20.

[0038] In this embodiment, the second connecting arm 6 can slide relative to the hinge arm 4, ensuring coordinated movement between components during the folding and unfolding of the bracket, as well as during adjustments to different positions, making the bracket's movement smoother and more flexible.

[0039] Working principle and usage process of this utility model: When the bracket needs to be stored, the first drive device 8 is activated to retract it, causing the sliding arm 3 to slide down along the support arm 2, thus reducing the height of the bracket; at the same time, the second drive device 9 is activated to retract it, causing the second slider 7 to slide down in the second groove 18 of the sliding arm 3, so that the first connecting arm 5 and the second connecting arm 6 pull the hinge arm 4, causing it to gradually approach the support arm 2 and fold. All components are tightly retracted, thereby effectively reducing the overall volume of the bracket, making it easier to transport and store. When the bracket is deployed, the first drive device 8 and the second drive device 9 move in opposite directions. The first drive device 8 extends and pushes the sliding arm 3 to slide upward along the support arm 2, raising the bracket to a suitable height. The second drive device 9 extends and pushes the second slider 7 to slide upward in the second slide groove 18 of the sliding arm 3. Through the first connecting arm 5 and the second connecting arm 6, the hinge arm 4 is pushed to unfold, so that it reaches a suitable angle and position, completing the deployment operation of the bracket and putting the bracket into a usable state. In actual use, if the height of the cleaning machine needs to be adjusted, the first drive device 8 can be restarted to extend or retract as needed to achieve fine adjustment of the height; if the angle of the cleaning machine needs to be changed to adapt to different cleaning tasks, the second drive device 9 can be started to adjust the position of the second slider 7, thereby adjusting the angle of the hinge arm 4 so that the cleaning machine can reach the optimal working angle.
