Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicle suction pipe technology, and in particular to a suction pipe limiting structure and a cleaning vehicle. Background Technology

[0002] A cleaning vehicle is a multi-functional cleaning device used for cleaning and hygiene. It is widely used for cleaning operations and material handling in public places such as hotels, shopping malls, commercial buildings, real estate developments, hospitals, schools, offices, libraries, exhibition centers, clubs, and private clubs.

[0003] The cleaning cart has a suction hose and a handle. Operators use the handle to operate the suction hose to collect debris. To increase the suction range, the suction hose is usually retractable, extending during use and retracting when not in use for easy storage. However, to prevent the hose from extending on its own after storage, it needs to be restrained. Current technology typically uses a rope to secure the hose, but this method is cumbersome and inconvenient.

[0004] Therefore, there is an urgent need to design a dust suction pipe limiting structure and a cleaning vehicle to solve one or more technical problems that are insufficient in the existing technology. Utility Model Content

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a dust suction pipe limiting structure, characterized in that it includes: an installation component, the installation component being fixedly connected to an external body, a limiting hook being slidably provided at one end of the installation component, the limiting hook being able to slide up and down in the installation component, the limiting hook sliding upward to release the restriction on the extension of the dust suction pipe, and a spring being provided at the tail end of the limiting hook, the spring pressing against the limiting hook.

[0006] In a preferred embodiment, one side of the limiting hook is further provided with an outwardly extending actuating portion.

[0007] In a preferred embodiment, the mounting component has a sliding groove at one end where the limiting hook is located, and at least one guide post is slidably provided in the mounting component. The guide post passes through the sliding groove, the tail end of the limiting hook is located in the sliding groove, and the limiting hook is fixedly connected to the guide post. The spring is sleeved in the guide post.

[0008] In a preferred embodiment, the actuating part is bent.

[0009] In another aspect, this utility model also provides a cleaning vehicle, characterized in that it includes: a cleaning vehicle body, an outlet is provided at a predetermined position of the cleaning vehicle body, a retractable suction pipe is provided inside the outlet, and a suction pipe limiting structure as described in any of the above embodiments is provided above the outlet.

[0010] The beneficial effects of this utility model are: by using a limiting hook, the vacuum cleaner hose is automatically restricted from extending after being retracted. Without controlling the movement of the limiting hook, the vacuum cleaner hose can only retract and cannot extend. Compared with the prior art, it is simpler and more convenient to use. Furthermore, the spring setting and the stability of the limiting hook make the structure reasonable, the cost low, and the practicality stronger. Attached Figure Description

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0018] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0019] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0020] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-2As shown, this utility model provides a vacuum cleaner pipe limiting structure, characterized in that it includes: a mounting component 10, which is fixedly connected to an external body, a limiting hook 13 slidably provided at one end of the mounting component 10, the limiting hook 13 being able to slide up and down in the mounting component 10, the limiting hook 13 sliding upward to release the extension restriction on the vacuum cleaner pipe 17, and a spring 15 provided at the tail end of the limiting hook 13, the spring 15 pressing against the limiting hook 13;

[0022] Specifically, the mounting component 10 is used to fix the cleaning cart to the external body. One end of the mounting component 10 is fixedly connected to the external body, and the other end is slidably provided with a limiting hook 13. The limiting hook 13 can slide in the mounting component 10, so that its end can cooperate with the vacuum hose 17 on the external body to restrict the extension of the vacuum hose 17. In the prior art, the vacuum hose 17 needs to be extended and is limited by space. Therefore, the vacuum hose 17 is usually made of flexible material, such as cloth, so that it can be both retracted and extended. Since the vacuum hose 17 performs vacuuming by suction, in order to avoid the vacuum hose 17 from flattening due to material reasons and affecting the vacuuming effect, the vacuum hose 17 is usually... The device has several support rings that support the suction pipe 17, allowing suction to pass smoothly through it for cleaning. In this application, the limiting hook 13 engages with one of the support rings on the suction pipe 17, preventing the suction pipe 17 from extending. When the suction pipe 17 needs to be used, the limiting hook 13 can be slid to disengage from the support rings, allowing the suction pipe 17 to extend. To prevent the limiting hook 13 from disengaging from the suction pipe 17 due to vibration during movement of the external body, a spring 15 is provided at the end of the limiting hook 13 to ensure its stability. Furthermore, to improve ease of use, the side of the limiting hook 13 facing away from the external body can be chamfered. This chamfer allows the suction pipe 17 to be retracted without sliding the limiting hook 13.

[0023] Furthermore, one side of the limiting hook 13 is also provided with an outwardly extending actuating part 14;

[0024] Specifically, to facilitate the operation of the limit hook 13 and its disengagement from the vacuum pipe 17, an outwardly extending actuating part 14 is provided on the side of the limit hook 13 facing away from the external main body. The extended actuating part 14 provides a pivoting support point, allowing the operator to easily actuate it. When the operator actuates the limit hook 13, the spring 15 is compressed, and the spring 15 generates a force acting on the limit hook 13. When the limit hook 13 loses the force applied by the operator, it automatically moves downward to reset under the action of the spring 15, thus eliminating the need for manual resetting by the operator.

[0025] Furthermore, the mounting component 10 is provided with a sliding groove 11 at one end of the limiting hook 13, and at least one guide post 12 is slidably provided in the mounting component 10. The guide post 12 passes into the sliding groove 11, the tail end of the limiting hook 13 is located in the sliding groove 11, and the limiting hook 13 is fixedly connected to the guide post 12. The spring 15 is sleeved in the guide post 12.

[0026] Specifically, a sliding groove 11 is provided at the bottom of the end of the mounting component 10 away from the connection with the external body. The tail end of the limiting hook 13 is located in the sliding groove 11. The limiting hook 13 can slide in the sliding groove 11, and the sliding distance is limited by the depth of the sliding groove 11. At least one guide post 12 is also provided on the end of the mounting component 10 with the sliding groove 11. In this embodiment, there are two guide posts 12, which are spaced apart. The number of springs 15 corresponds to the number of guide posts 12. The double-point limiting prevents the limiting hook 13 from tilting when sliding. The two guide posts 12 are inserted into the mounting component 10 and can slide on the mounting component 10. One end of the guide post 12 is inserted into the sliding groove 11 and fixedly connected to the limiting hook 13. When the limiting hook 13 slides, it drives the guide post 12 to move up and down on the mounting component 10. The spring 15 is sleeved on the outside of the guide post 12. When the limiting hook 13 moves, it will squeeze the spring 15.

[0027] Furthermore, the actuating part 14 is bent.

[0028] Specifically, to avoid the actuating part 14 being too close to the vacuum tube 17, making it inconvenient for staff to actuate, in this embodiment, the actuating part 14 is bent so that there is at least a finger's distance between it and the vacuum tube 17, so as to facilitate actuation.

[0029] like Figure 3 As shown, another aspect of this utility model provides a cleaning vehicle, including: a cleaning vehicle body 16, an outlet 18 is provided at a predetermined position of the cleaning vehicle body 16, a retractable suction pipe 17 is provided inside the outlet 18, and a limiting structure for the suction pipe 17 as described in any of the above embodiments is provided above the outlet 18.

[0030] Specifically, one end of the mounting part 10 is fixedly connected to the top of the outlet 18, and the limiting hook 13 is located in front of the outlet 18. The limiting hook 13 cooperates with the support ring on the suction pipe 17 to restrict the extension of the suction pipe 17.

[0031] In summary, the limiting hook 13 automatically restricts the vacuum hose 17 from extending after it is retracted. Without manipulating the limiting hook 13, the vacuum hose 17 can only retract and cannot extend. Compared with existing technologies, it is simpler and more convenient to use. Furthermore, the spring 15 and the stability of the limiting hook 13 make the structure reasonable, cost-effective, and more practical.

[0032] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
