Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning accessories technology, specifically a foldable and retractable high-pressure cleaner pipe cleaning kit. Background Technology

[0002] High-pressure cleaning kits are the core components of high-pressure cleaning equipment, containing a variety of accessories to achieve efficient cleaning functions. In high-pressure cleaning pipeline cleaning operations, cleaning kits need to integrate various accessories such as pipes, nozzles, and connectors. Their ease of storage, accessory protection, and operational stability directly affect operational efficiency.

[0003] The following problems were found in the relevant technology: Kit accessories (such as nozzles, reducers, and quick-connect fittings) are mostly stored loosely without a categorized or fixed structure, making them prone to slipping out of the toolbox and being lost during transport. Furthermore, since most accessories are made of metal or hard plastic, collisions can easily cause surface scratches and interface deformation, affecting the sealing performance and service life of the accessories. While some kits have simple partitions, they lack cushioning and protective designs, making them unable to withstand damage to the accessories from external impacts. To address these issues, we propose a foldable and retractable high-pressure washer pipeline cleaning kit.

[0004] 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

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the issue of carrying high-pressure cleaning accessories in the prior art, this utility model provides a foldable and retractable high-pressure cleaner pipe cleaning kit. It employs a portable foldable storage kit combined with a modular design to achieve easy carrying and separate protection. The specific technical solution is as follows:

[0006] A foldable and retractable high-pressure washer pipe cleaning kit includes a lid and a double-layer storage box. The lid and the double-layer storage box are stacked together by a folding mechanism. The interior of the double-layer storage box is divided into an independent pipe storage cavity and a fitting storage cavity along the height direction. A coiled conical tube is rotatably arranged inside the pipe storage cavity, and a pipe is spirally coiled on the curved outer wall of the coiled conical tube. A tightening fitting located on the outer periphery of the pipe is slidably arranged on the inner wall of the pipe storage cavity, and a tightening mechanism is provided inside the pipe storage cavity to drive the tightening fitting to feed and move.

[0007] In the above technical solution, the tightening component includes a drive shaft that is rotatably disposed on the inner wall of the pipe receiving cavity, and a movable seat that is fixed to the outer wall of the tightening fitting is threadedly connected to the outer wall of the drive shaft.

[0008] The inner wall of the pipe receiving cavity is fixedly connected to a directional guide rod parallel to the drive shaft, and the outer wall of the directional guide rod is sleeved with a guide seat fixed to the outer wall of the tight pipe fitting.

[0009] The accessory storage cavity is fitted with an elastic liner, and the top of the elastic liner is evenly provided with placement slots, and pipe fittings are fitted inside the placement slots.

[0010] The shape of the tight fitting near the coil cone matches the curved surface of the coil cone.

[0011] The retractable component includes a damping hinge disposed between the lid and the double-layer storage box.

[0012] The outer wall of the box cover is rotatably provided with a support leg, and the support leg is provided with a locking groove for a through bolt.

[0013] The top of the coil cone is fitted with a removable limiting top.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The two storage compartments of the double-layer storage box (pipe storage compartment and accessory storage compartment) can be folded together. The lid can be further folded and fastened to the pipe storage compartment. After folding, the overall volume is only 1 / 3 of the unfolded volume (approximately 0.07m). 3 Compared to traditional fixed case kits, it is more than 65% smaller and can be easily packed into a handbag or car trunk, making door-to-door delivery more convenient; the damping design of the damping hinge can control the folding / unfolding speed, avoid collisions that may cause parts to shift, and improve operational safety.

[0016] 2. Foldable support leg design on the outer wall of the lid: When in use, rotate the support leg to be flush with the bottom of the double-layer storage box. After locking with bolts, it can form a stable support for the kit without relying on external brackets. It is suitable for various working scenarios such as wet ground and uneven tabletops. When folded, the support leg can be retracted to fit the outer wall of the lid without taking up extra storage space, balancing support stability and portability.

[0017] 3. The outer wall of the coil cone is equipped with a spiral baffle, forming a spiral groove that matches the pipe diameter. The pipe can be wound in an orderly manner along the groove, avoiding the knotting problem of manual winding. The detachable limiting top of the coil cone can limit the top of the pipe to prevent slippage. The inner wall of the fitting fits the curved surface of the coil cone, which can tightly fit the outer wall of the pipe and evenly tighten the pipe in the spiral groove. With the guidance of the guide rod, the tightening process is ensured to be without deviation, effectively preventing the pipe from loosening and shifting during transportation, reducing pipe wall wear, and extending the service life of the pipe.

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] A foldable and retractable high-pressure washer pipe cleaning kit includes a lid 1 and a double-layer storage box 2. The lid 1 and the double-layer storage box 2 are stacked together by a folding mechanism, allowing the double-layer storage box 2 and the lid 1 to be unfolded and folded together for easy portability. The interior of the double-layer storage box 2 is divided along its height into independent pipe storage chambers 3 and accessory storage chambers 4. The double-layer storage box 2 consists of two foldable box bodies, forming a three-layer folding structure with the lid 1. By storing the accessories needed for the high-pressure washer pipe cleaning process in layers, it avoids mixing and damage.

[0026] The pipe receiving cavity 3 is equipped with a rotating coil cone 5, and the pipe 6 is spirally coiled on the curved outer wall of the coil cone 5. A bearing is installed at the bottom of the inner wall of the pipe receiving cavity 3 through a bearing seat. A rotating shaft is installed inside the bearing. The center of the coil cone 5 is fixedly sleeved on the outer wall of the rotating shaft through an opening. A baffle is fixedly installed on the outer wall of the coil cone 5 from top to bottom in a spiral, so that the baffle and the arc surface of the coil cone 5 form a spiral channel. The cleaning pipe of the high pressure washer is coiled on the channel in sequence.

[0027] The inner wall of the pipe receiving cavity 3 is slidably provided with a tightening fitting 7 located on the outer periphery of the pipe 6, and the inside of the pipe receiving cavity 3 is provided with a tightening component that drives the tightening fitting 7 to move forward. After the cleaning pipes of the high-pressure cleaner are coiled on the channel in sequence, the tightening component causes the two tightening fittings 7 to move relative to each other to the outer wall of the pipe, thereby tightening the cleaning pipes on the coil cone 5.

[0028] The tightening component includes a drive shaft 10 rotatably mounted on the inner wall of the pipe receiving cavity 3. A movable seat 11, fixed to the outer wall of the tightening fitting 7, is threadedly connected to the outer wall of the drive shaft 10. The drive shaft 10 is located near the inner wall of the pipe receiving cavity 3. Both ends of the drive shaft 10 rotate within the pipe receiving cavity 3 via bearings mounted on bearing seats on the inner wall of the pipe receiving cavity 3. Two sets of external threads with opposite threads and the same pitch are formed at both ends of the drive shaft 10, and the two movable seats 11 are connected to the two sets of external threads through threaded through holes penetrating the inner cavity. One end of the drive shaft 10 extends outwards for easy operation.

[0029] After rotating the drive shaft 10, the two movable seats 11 that are threaded to the drive shaft 10 drive the two tightening pipe parts 7 to move relative to each other, so that the tightening pipe parts 7 fit against the pipe surface of the outer wall of the coil cone 5.

[0030] It is worth noting that a directional guide rod 12 parallel to the drive shaft 10 is fixedly connected to the inner wall of the pipe receiving cavity 3, and a guide seat 13 fixed to the outer wall of the pipe fitting 7 is sleeved on the outer wall of the directional guide rod 12. The directional guide rod 12 is fixedly installed on the inner wall of the other side of the pipe receiving cavity 3, so that the directional guide rod 12 and the drive shaft 10 are respectively close to the two sides of the inner wall of the pipe receiving cavity 3.

[0031] The stability of the moving direction of the clamping pipe 7 is ensured by the directional guide rod 12 parallel to the drive shaft 10.

[0032] In addition, an elastic liner 8 is embedded inside the accessory storage cavity 4, and placement slots 9 are evenly distributed on the top of the elastic liner 8. Pipe fittings are embedded inside the placement slots 9. The placement slots 9 are used to hold fittings that are used in conjunction with the cleaning pipes during the high-pressure washer cleaning process.

[0033] The elastic lining, made of rubber, ensures that the accessories required for the high-pressure washer pipe cleaning process can be stably secured inside the placement slot 9.

[0034] The shape of the tightening fitting 7 on the side near the coil cone 5 matches the curved surface of the coil cone 5. This ensures the tightness of the tightening fitting 7 and the pipe wrapped around the outside of the coil cone 5, preventing the pipe from loosening and falling off.

[0035] In addition, the storage components include a damping hinge 14 disposed between the lid 1 and the double-layer storage box 2. The two storage cavities of the double-layer storage box 2 are connected by the damping hinge 14. The pipe storage cavity 3 is connected to the lid 1 by the damping hinge 14. At the same time, the lid 1 is connected to the pipe storage cavity 3 and the accessory storage cavity 4 by the same damping hinge 14.

[0036] The outer wall of the lid 1 is rotatably provided with a support leg 15, and the support leg 15 is provided with a locking groove 16 for passing through the bolt. Four threaded seats connected to the bolt are fixedly installed on the rear surface of the lid 1. The four threaded seats are used to fold back the locking support leg 15 and unfold the locking support leg 15 respectively. The two support legs 15 rotate in a staggered manner through the pivot on the back of the lid 1.

[0037] When folding, the support leg 15 is folded up. When in use, the support leg 15 is rotated to a position flush with the bottom of the double-layer storage box 2. The support leg 15 is locked by passing two bolts through the locking groove 16 and threaded onto the threaded seat. The support leg 15 supports the box cover 1, ensuring stability during use.

[0038] Furthermore, a detachable limiting top 17 is inserted into the top of the coil cone 5, and a hexagonal locking block is fixedly installed at the bottom of the limiting top 17. A hexagonal locking groove with an interference fit to the locking block is opened on the top of the coil cone 5, so that the limiting top 17 is locked onto the top of the coil cone 5. This not only limits the pipe wound on the coil cone 5, but also allows the operating rod on the outer wall of the limiting top 17 to drive the coil cone 5 to rotate for pipe winding.
