Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure cleaning machines, in particular to a telescopic hanging rod of a high-pressure cleaning machine. Background Art

[0002] A high-pressure cleaner is a machine that uses a power device to generate high-pressure water from a high-pressure plunger pump to wash the surface of an object. It can peel off and wash away dirt, thereby achieving the purpose of cleaning the surface of the object. The rear side wall, left side wall, or right side wall of the existing high-pressure cleaner housing is provided with a hook, which is used to hang components such as a water pipe or a foam spray bottle. For example, the China Patent Network discloses a high-pressure cleaner [Authorization Announcement No.: CN206676808U], which includes a body, an electric wire connected to the back of the body, a water inlet and a water outlet on one side of the body, and the water outlet is connected to the spray gun through a water pipe. The back of the body is provided with a winding drum for winding the electric wire, and a kettle hook is protruding from the back of the winding drum. A water pipe hook is provided on the upper part of one side of the body to hang a water pipe.

[0003] The above-mentioned high-pressure cleaner has the following defects: the hook is directly fixed on the casing or the hook and the casing are integrally formed. Since the hook is arranged to protrude outward relative to the body, the size of the entire machine will be much larger, affecting the overall packaging size, making the size of the entire machine packaging box larger, and making the packaging cost high. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a retractable hanging rod for a high-pressure cleaner. The technical problem to be solved by this utility model is: how to solve the problem that the packaging size of the high-pressure cleaner is larger after the existing hook is fixed on the casing.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A retractable hanging rod for a high-pressure cleaning machine includes a housing and a hanging rod, characterized in that a side wall of the housing has an inwardly protruding mounting boss, a sliding cavity is provided in the mounting boss, the hanging rod has a mounting portion, the mounting portion is slidably arranged in the sliding cavity, and a limiting structure is provided between the sliding cavity and the mounting portion to limit the mounting portion from escaping the sliding cavity.

[0007] In this structure, a mounting boss is provided inside the casing, and the mounting portion of the hanging rod is slidably provided in the sliding cavity of the mounting boss. The mounting portion can slide inward or outward along the sliding cavity. When the high-pressure cleaning machine is packaged, the hanging rod is pushed to make the mounting portion slide toward the inside of the casing, thereby making the hanging rod gradually approach the outer wall of the casing, thereby significantly reducing the packaging size of the high-pressure cleaning machine. When the high-pressure cleaning machine is in use, the hanging rod is pulled outward to make the mounting portion slide outward, thereby making the hanging rod gradually move away from the outer wall of the casing, and the setting of the limiting structure can prevent the hanging rod from falling out of the sliding cavity.

[0008] In the aforementioned retractable hanging rod for a high-pressure cleaner, the limiting structure includes a limiting groove on the outer wall of the mounting portion, the limiting groove being arranged along the sliding direction of the mounting portion, one end of the limiting groove having a limiting surface, and a limiting block on the side wall of the mounting boss extending into the limiting groove. When the hanging rod moves outward to the limit position, the end surface of the limiting block abuts against the limiting surface. The cooperation between the limiting block and the limiting surface prevents the mounting portion from falling out of the sliding cavity.

[0009] In the aforementioned retractable hanging rod for a high-pressure cleaner, the retaining grooves are formed on both the left and right sidewalls of the mounting portion, and the retaining blocks are provided on both the left and right sides of the mounting boss. This structure allows both the left and right sides of the mounting portion to be retained, ensuring the stability of the retaining position of the mounting portion.

[0010] In the aforementioned retractable hanging rod for a high-pressure cleaner, the mounting portion has a first elastic arm at one end facing the interior of the housing, a protrusion at the outer end of the first elastic arm, and a closed inner end of the mounting boss having a snap-in hole for the protrusion to engage. When the hanging rod is moved inward to its extreme position, the protrusion snaps into the snap-in hole, thereby securing the hanging rod in that position and ensuring that the hanging rod remains in that position during packaging.

[0011] In the aforementioned retractable hanging rod for a high-pressure cleaner, the protrusion is a triangular protrusion, the tip of which is capable of closely contacting the inner wall of the sliding cavity. This structural design ensures that when the mounting portion moves outward, the tip of the triangular protrusion closely contacts the inner wall of the sliding cavity, creating a certain frictional resistance between the triangular protrusion and the inner wall of the sliding cavity. This provides a certain damping effect on the outward movement of the mounting portion, allowing the hanging rod to be pulled out slowly.

[0012] In the aforementioned retractable hanging rod for a high-pressure cleaner, the first elastic arm is provided on both the left and right sides of the mounting portion, and the first engaging hole is provided on both the left and right sides of the closed end. This structure further improves the positioning effect of the hanging rod when it moves inward to the extreme position, and the provision of the two first elastic arms also enhances the damping effect.

[0013] In the above-mentioned retractable hanging rod of a high-pressure cleaning machine, a through-hole communicating with the sliding cavity is provided on the lower surface of the mounting boss, the through-hole is in the shape of an elongated strip and is arranged along the sliding direction of the mounting portion, the mounting portion has two elastic arms, the outer ends of the two elastic arms have a positioning protrusion located in the through-hole, a stopper is provided on the bottom surface of the sliding cavity, and when the hanging rod moves outward to the extreme position, the positioning protrusion is located outside the stopper and abuts against the stopper. When the hanging rod moves outward, the positioning protrusion moves outward in the through-hole, and when the positioning protrusion contacts and passes the stopper, the positioning protrusion is located outside the stopper and abuts against the stopper, at which point the hanging rod moves outward to the extreme position. At this time, the hanging rod will not move toward the interior of the casing without the action of external force, so that the hanging rod in this state is convenient for the placement and hanging of high-pressure water pipes or other components.

[0014] In the aforementioned retractable hanging rod for a high-pressure cleaner, the positioning protrusion is a downwardly projecting inverted triangular protrusion, and the stopper is an upwardly projecting triangular protrusion. The coordinated structure of the inverted triangular protrusion and the upright triangular protrusion allows the positioning protrusion to smoothly pass over the stopper. Furthermore, with a slight application of force, the positioning protrusion can be pushed inward over the stopper, thereby causing the mounting portion to move inward.

[0015] Compared with the prior art, the retractable hanging rod of the high-pressure cleaning machine of the present invention has the following advantages: the present structure is provided with a mounting boss inside the casing, and the mounting portion of the hanging rod is slidably arranged in the sliding cavity of the mounting boss, and the mounting portion can slide inward or outward along the sliding cavity. When the entire high-pressure cleaning machine is packaged, the hanging rod is pushed to make the mounting portion slide toward the inside of the casing, and then the hanging rod is gradually approached to the outer wall of the casing, thereby significantly reducing the packaging size of the entire high-pressure cleaning machine; when the high-pressure cleaning machine is in use, the hanging rod is pulled outward to make the sliding portion slide outward, and then the hanging rod is gradually away from the outer wall of the casing, and the setting of the limiting structure can prevent the hanging rod from falling out of the sliding cavity.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 7 As shown, the retractable hanging rod of the high-pressure cleaning machine includes a casing 1 and a hanging rod 2. A side wall of the casing 1 has an inwardly protruding mounting boss 3, and a sliding cavity 30 is provided in the mounting boss 3. The hanging rod 2 has a mounting portion 20, and the mounting portion 20 is slidably arranged in the sliding cavity 30. There is a limiting structure between the sliding cavity 30 and the mounting portion 20 to limit the mounting portion 20 from escaping the sliding cavity 30. In this structure, a mounting boss 3 is provided inside the casing 1, and the mounting portion 20 of the hanging rod 2 is slidably provided in the sliding cavity 30 of the mounting boss 3. The mounting portion 20 can slide inward or outward along the sliding cavity 30. When the high-pressure cleaning machine is packaged, the hanging rod 2 is pushed to make the mounting portion 20 slide toward the inside of the casing 1, and then the hanging rod 2 gradually approaches the outer wall of the casing 1, thereby significantly reducing the packaging size of the high-pressure cleaning machine; when the high-pressure cleaning machine is in use, the hanging rod 2 is pulled outward to make the mounting portion 20 slide outward, and then the hanging rod 2 gradually moves away from the outer wall of the casing 1, and the setting of the limiting structure can prevent the hanging rod 2 from falling out of the sliding cavity 30.

[0026] like Figure 1 、 Figure 5 and Figure 6As shown, the limiting structure includes a limiting groove 21 on the outer wall of the mounting portion 20, which is arranged along the sliding direction of the mounting portion 20. One end of the limiting groove 21 has a limiting surface 22. The side wall of the mounting boss 3 has a limiting block 31 extending into the limiting groove 21. When the hanging rod 2 moves outward to the extreme position, the end surface of the limiting block 31 abuts against the limiting surface 22. In this embodiment, the limiting grooves 21 are provided on both the left and right side walls of the mounting portion 20, and the limiting blocks 31 are provided on both the left and right sides of the mounting boss 3. The cooperation between the limiting blocks 31 and the limiting surface 22 prevents the mounting portion 20 from falling out of the sliding cavity 30.

[0027] Furthermore, the end of the mounting portion 20 facing the interior of the housing 1 has an elastic arm 23, and the outer end of the elastic arm 23 has a protrusion 230. The inner end of the mounting boss 3 is a closed end 32, which is provided with a snap-in hole 320 for the protrusion 230 to engage. In this embodiment, the elastic arm 23 is provided on both the left and right sides of the mounting portion 20, and the snap-in holes 320 are provided on both the left and right sides of the closed end 32. When the hanging rod 2 moves inward to the extreme position, the protrusion 230 snaps into the snap-in hole 320, thereby positioning the hanging rod 2 in this state and ensuring that the hanging rod 2 is always in this position during packaging. The protrusion 230 is a triangular protrusion, and the tip 231 of the triangular protrusion can be in close contact with the inner wall of the sliding cavity 30. The design of this structure ensures that when the mounting portion 20 moves outward, the tip 231 of the triangular protrusion is in close contact with the inner wall of the sliding cavity 30, and a certain friction resistance is formed between the triangular protrusion and the inner wall of the sliding cavity 30, so that the mounting portion 20 has a certain damping feeling when moving outward, and the hanging rod 2 is slowly pulled out.

[0028] like Figure 1 、 Figure 4 and Figure 7 As shown, the lower surface of the mounting boss 3 defines a through opening 33 that communicates with the sliding cavity 30. The through opening 33 is elongated and arranged along the sliding direction of the mounting portion 20. The mounting portion 20 includes a second elastic arm 24, the outer end of which includes a positioning protrusion 240 positioned within the through opening 33. A stopper 34 is provided on the bottom surface of the sliding cavity 30. When the hanging rod 2 moves outward to the extreme position, the positioning protrusion 240 is located outside of the stopper 34 and abuts against it. In this embodiment, the positioning protrusion 240 is a downwardly protruding inverted triangular protrusion, while the stopper 34 is an upwardly protruding triangular protrusion. When the hanging rod 2 moves outward, the positioning protrusion 240 is located in the through opening 33 and moves outward. When the positioning protrusion 240 contacts the stop block 34 and passes over the stop block 34, the positioning protrusion 240 is located on the outside of the stop block 34 and abuts against the stop block 34. At this time, the hanging rod 2 moves outward to the extreme position. At this time, the hanging rod 2 will not move toward the inside of the casing 1 without external force, so that the hanging rod 2 is in this state to facilitate the placement and hanging of high-pressure water pipes or other components.
