Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning equipment technology, and more specifically, it relates to a high-pressure cleaning device. Background Technology

[0002] High-pressure cleaning equipment uses a high-pressure water pump to pressurize water to tens to hundreds of megapascals, forming a high-speed jet through nozzles to efficiently remove surface dirt, oil stains, and coatings. Its core components include a high-pressure pump, hoses, and spray guns, and it features both hot and cold water modes, making it suitable for industrial rust removal, vehicle washing, building renovation, and other applications.

[0003] Small high-pressure cleaning equipment is widely used in daily vehicle cleaning and yard cleaning. In the existing technology, in order to improve the convenience of movement, the high-pressure cleaning equipment such as water tank and high-pressure water pump are placed on a mobile cart for movement. Generally, the mobile cart has a handle, which takes up a certain amount of space and height, and is not convenient to store when not in use.

[0004] In addition, during the cleaning of car surfaces and home yards, cleaning items such as high-pressure spray guns are temporarily placed. Existing high-pressure cleaning equipment does not provide a corresponding temporary placement area, which affects the ease of use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a high-pressure cleaning device to solve the technical problems mentioned in the background art, such as the large space occupied when not in use and the poor functionality of temporary item placement during use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A high-pressure cleaning device includes a base with casters at its bottom. A water tank and a water pump are mounted on the base. The water pump has an inlet pipe at its input end and a supply pipe at its output end. The inlet pipe extends movably into the water tank. A high-pressure water gun is connected to the end of the supply pipe. A fixed frame is mounted on one side of the base. A lifting frame is mounted on the fixed frame and has a pull handle. A placement rack is mounted on the inner side of the lifting frame and can be tilted and limited. A storage cavity is formed at the bottom of the base, allowing the fixed frame and lifting frame to be stored in the storage cavity. A fixed seat is mounted on one side of the base, with a locking structure that secures the fixed frame.

[0010] The present invention is further configured such that a limiting plate is slidably disposed within the storage cavity, and a limiting edge is provided at the outer end of the storage cavity, thereby restricting the limiting plate from disengaging from the storage cavity. The fixing frame is elastically and rotatably disposed on the limiting plate. When not in use, the locking limit between the locking pin and the locking groove can be released, and the fixing frame carrying the lifting frame can be flipped downwards, so that the fixing frame and the lifting frame return to a horizontal state, and then pushed inwards into the storage cavity. At this time, the placement frame is in a folded state, so that the fixing frame and the lifting frame can be completely folded and stored inside the base, thereby reducing the overall footprint. The setting of the limiting edge can improve the movement and connection stability between the fixing frame and the base.

[0011] The present invention is further configured such that the locking structure includes a locking pin, the locking pin being slidably inserted into the fixed base, and a locking groove being provided on the side wall of the fixed frame, the locking pin being able to be inserted into the locking groove. The cooperation between the locking pin and the locking groove can realize a detachable limiting connection between the fixed frame and the fixed base, thereby improving the connection stability between the fixed frame and the base and improving the convenience of overall pulling and moving.

[0012] The present invention is further configured such that a pull cap is provided at the outer end of the locking post, and a spring is provided between the pull cap and the fixed seat. The spring is sleeved on the outside of the locking post. The pull cap facilitates pulling the locking post outward, and the spring is used for the automatic reset of the locking post to realize the automatic engagement between the locking post and the locking groove.

[0013] The present invention is further configured such that a first limiting block and a second limiting block are provided on the lifting frame in conjunction with the placement frame. The first limiting block is used to limit the placement frame when it is horizontally flipped, and the second limiting block is used to limit the placement frame when it is folded and stored. This can improve the stability of the placement frame during use and when it is folded and stored.

[0014] The present invention is further configured such that the fixed frame has a lifting groove, the bottom end of the lifting frame is slidably located in the lifting groove, and a locking member is threaded on the side wall of the fixed frame. The inner end of the locking member extends into the lifting groove and presses against the side wall of the lifting frame. The lifting groove allows for the lifting and lowering adjustment of the lifting frame on the fixed frame. After adjusting to a suitable height, the locking member is tightened so that the inner end of the locking member presses against and fixes against the side wall of the lifting frame, thereby locking and fixing the lifting frame on the fixed frame. This also locks and fixes the height of the pull handle and the placement rack, allowing for flexible adjustment of the height of the pull handle and the placement rack, thus improving ease of use.

[0015] The present invention is further configured such that a rotating seat is provided on the limiting plate, and an installation groove is provided on the rotating seat. A rotating shaft is provided at the bottom end of the fixed frame. The rotating shaft is set in the installation groove through a bearing, and a torsion spring is provided between the rotating shaft and the inner wall of the installation groove. In use, the lifting frame and the fixed frame can be pulled out of the storage box by pulling the handle. When the limiting plate is in contact with the limiting edge, the fixed frame can automatically flip upward with the lifting frame under the action of the torsion spring. Then, the locking pin is pulled outward through the pulling cap, so that the fixed frame is located between the two sets of fixed seats. Then, the pulling cap is released, and the locking pin can be inserted into the locking groove under the action of the spring, thereby realizing the connection and fixation between the fixed seat and the fixed frame, thus facilitating the overall pulling and moving.

[0016] The present invention is further configured such that the lifting frame is provided with a flipping shaft, the placement frame is provided with a flipping groove, and a damping pad is provided on the inner wall of the flipping groove. The placement frame is rotatably mounted on the flipping shaft through the cooperation of the flipping groove and the damping pad. In this way, the placement frame can be flipped outward during use, so that it can be used for placing small items, high-pressure water guns, etc. during high-pressure cleaning. This can improve the convenience of high-pressure cleaning and avoid the situation where there is nowhere to put cleaning gap parts, high-pressure water guns, etc.
