Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning machines, in particular to a conduit installation structure of a cleaning machine. Background Art

[0002] Existing high-pressure cleaning machines generally have a hose reel with a high-pressure hose wound on it. When the high-pressure hose is pulled or recovered, the position of the high-pressure hose is moved at will. In order to solve the problem of the high-pressure hose running around, a high-pressure hose limiting structure is generally installed on the hose reel. The high-pressure hose is inserted into the limiting structure. When the high-pressure hose is used or stored, the high-pressure hose is limited in the corresponding activity range.

[0003] At present, the China Patent Network discloses a structure for reducing the resistance of a high-pressure pipe channel of a pipe reel and a high-pressure cleaning machine [Authorization Announcement No.: CN216302969U], which includes a shell, a rolling assembly and a ball pressure plate. The rolling assembly includes balls and ball shafts. The balls are mounted on the ball shafts and are clearance-matched with the ball shafts. In actual applications, the balls and the ball shafts are both installed in the accommodating cavity, and the two ends of the ball shafts are installed on the inner wall of the accommodating cavity. The balls can rotate freely on the ball shafts. When the high-pressure pipe moves, the balls are pulled by the friction of the high-pressure pipe and rotate to realize the wear of the high-pressure pipe in the reciprocating motion.

[0004] The above-mentioned ball pressure plate is fixed on the shell, and the high-pressure tube is inserted into the ball pressure plate. The ball pressure plate limits the high-pressure tube to prevent the high-pressure tube from running around during the storage process. The high-pressure tube limiting structure has the following defects: the structure of the ball pressure plate is complicated and inconvenient to process and manufacture. At the same time, the connection structure between the ball pressure plate and the shell is also relatively complicated, which is not convenient for the installation of the ball pressure plate on the shell; secondly, in order to avoid a large friction between the high-pressure tube and the inner wall of the ball pressure plate, the above-mentioned structure adopts a ball shaft set inside the ball pressure plate, which further increases the complexity and assembly degree of the high-pressure tube limiting structure. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a conduit installation structure for a cleaning machine. The technical problem to be solved by the utility model is: how to solve the problem that the existing high-pressure pipe limiting method has a complex structure and is inconvenient to install.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A duct installation structure for a cleaning machine includes a shell and a duct, wherein the duct is U-shaped and has two connecting ends, and the shell is provided with two snap-in holes, each connecting end is respectively inserted into a corresponding snap-in hole and snap-in with the snap-in hole.

[0008] This structure directly inserts the U-shaped conduit into the clamping hole of the shell, and the two connecting ends of the conduit are clamped with the clamping hole to realize the installation and positioning of the conduit. When in use, the high-pressure tube passes through the conduit setting, and the U-shaped conduit plays a limiting role in the retraction and release of the high-pressure tube, avoiding the problem of the high-pressure tube running around. This structure uses a U-shaped conduit to limit the retraction and release of the high-pressure tube, which greatly simplifies the limiting structure of the high-pressure tube and reduces the manufacturing cost. The U-shaped conduit is clamped and positioned after being plugged into the shell, and the installation of the U-shaped conduit is more convenient.

[0009] In the above-mentioned catheter installation structure of a cleaning machine, a clamping groove is provided on the outer peripheral surface of the connecting end, and an elastic buckle is provided in the clamping hole, and the elastic buckle can be embedded in the clamping groove. Through the arrangement of this structure, when the connecting end is inserted into the clamping hole, the elastic buckle is embedded in the clamping groove, so that the connecting end is clamped in the clamping hole, and the catheter cannot be pulled out from the shell, thereby realizing the clamping positioning of the catheter. The clamping method has a simple structure and is convenient for assembling the catheter and the shell.

[0010] In the above-mentioned catheter installation structure of a cleaning machine, a protruding column is provided on the inner side surface of the shell, the clamping hole extends into the protruding column, two cutting grooves arranged along the axial direction are provided on the protruding column, an elastic arm is formed between the two cutting grooves, and the elastic buckle is arranged on the inner side surface of the elastic arm. Through the arrangement of this structure, when the connecting end is inserted into the clamping hole, the outer peripheral surface of the connecting end abuts against the elastic buckle to push the elastic arm outward, that is, the elastic arm has a certain elastic deformation performance, and when the elastic buckle corresponds to the clamping slot, the elastic buckle is embedded in the clamping slot. This structure facilitates the installation of the catheter and the shell.

[0011] In the above-mentioned cleaning machine conduit installation structure, the outer end of the protruding column has a limiting plate, and when the connection end abuts against the limiting plate, the elastic buckle is embedded in the card slot. Through the arrangement of this structure, the limiting plate limits the insertion of the connection end, and when the end of the connection end abuts against the limiting plate, the elastic buckle is just embedded in the card slot.

[0012] In the above-mentioned conduit installation structure of a cleaning machine, the outer side surface of the housing has an annular boss at a position corresponding to the clamping hole, and the connecting end is inserted into the boss. Through the arrangement of this structure, the arrangement of the boss facilitates the plugging of the connecting end.

[0013] In the above-mentioned conduit installation structure of a cleaning machine, the conduit is made of metal material and is a hollow structure. Through the arrangement of this structure, the conduit made of metal material has a higher structural strength and is not easy to deform. The conduit is a hollow structure, which reduces the weight of the conduit and also reduces the cost of the conduit.

[0014] Compared with the prior art, the catheter installation structure of the cleaning machine of the utility model has the following advantages: the structure adopts a method of directly inserting the U-shaped catheter into the clamping hole of the shell, and the two connecting ends of the catheter are clamped with the clamping hole to realize the installation and positioning of the catheter. When in use, the high-pressure tube passes through the catheter setting, and the U-shaped catheter plays a limiting role in the retraction and release of the high-pressure tube, avoiding the problem of the high-pressure tube running around. The structure uses a U-shaped catheter to limit the retraction and release of the high-pressure tube, which greatly simplifies the limiting structure of the high-pressure tube and reduces the manufacturing cost. The U-shaped catheter is clamped and positioned after being plugged into the shell, and the installation of the U-shaped catheter is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
