Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicle technology, and in particular to a detachable anti-collision buffer structure for a cleaning vehicle. Background Technology

[0002] Sweeping and cleaning vehicles can complete ground sweeping, curb sweeping, curb washing, and post-sweeping watering in one operation. They are suitable for sweeping operations in various climates and on different types of dry surfaces. Existing sweeping and cleaning vehicles mainly use a combination of main brushes and side brushes to sweep up litter. However, the side brushes of existing sweeping and cleaning vehicles lack anti-collision functionality. During cleaning, the side brushes are prone to colliding with curbs or stones, causing damage and reducing their lifespan, thus failing to meet usage requirements.

[0003] The utility model patent with publication number CN216892171U provides a side brush anti-collision device for a cleaning vehicle. It protects the side brush body with a protective plate and reduces the impact force of a collision through the elasticity of the first and second compression springs. At the same time, the two sets of first compression springs and two sets of second compression springs work together to place the side brush body in the middle of the two sets of protective plates, protecting the side brush body and preventing it from colliding with roadside pebbles or stones and causing damage. This improves the service life of the side brush body and meets the usage requirements.

[0004] The above solution protects the main body of the side brush with a protective plate, but the protective plate is not easy to disassemble, repair or replace after it is damaged, so it is not very practical. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable anti-collision buffer structure for cleaning vehicles, so as to facilitate the removal of the protective plate for maintenance and replacement, thereby improving practicality.

[0006] To achieve the above objectives, this utility model provides a detachable anti-collision buffer structure for a cleaning vehicle, including a side brush body and an anti-collision assembly. The anti-collision assembly includes an elastic rod, a mounting base, a protective plate, a connecting screw, and a positioning rod. The elastic rod is disposed on the side of the side brush body. The mounting base is fixedly connected to the elastic rod, and the mounting base is located at the end of the elastic rod away from the side brush body. One end of the connecting screw is rotatably connected to the mounting base. The protective plate is provided with a threaded cavity and a positioning cavity at intervals. The other end of the connecting screw is threadedly connected to the protective plate, and the end of the connecting screw away from the mounting base is located inside the threaded cavity. One end of the positioning rod is fixedly connected to the mounting base, and the other end of the positioning rod is located inside the positioning cavity.

[0007] The connecting screw has a connecting ring at its end, and the mounting base has an annular groove that matches the connecting ring, with the connecting ring located inside the annular groove.

[0008] The anti-collision component further includes a rotating plate, which is fixedly connected to the connecting ring and is located on the outside of the connecting ring.

[0009] The elastic rod includes a fixed outer rod, a spring, and a movable inner rod. One end of the fixed outer rod is fixedly connected to the side brush body, and one end of the movable inner rod is slidably connected to the fixed outer rod. The movable inner rod is located at the end of the fixed outer rod away from the side brush body. Both ends of the spring are fixedly connected to the fixed outer rod and the movable inner rod, respectively. The spring is located inside the fixed outer rod. The mounting base is fixedly connected to the movable inner rod and is located at the end of the movable inner rod away from the fixed outer rod.

[0010] The anti-collision component also includes a rubber sheet, which is fixedly connected to the protective plate and is located on the side of the protective plate away from the mounting base.

[0011] This utility model discloses a detachable anti-collision buffer structure for a cleaning vehicle. When the protective plate is damaged and needs to be disassembled for repair, the connecting screw can be turned to disengage it from the threaded cavity, allowing the protective plate to be pulled out for easy repair and replacement. This makes the repair and replacement of the protective plate very convenient, thereby improving its practicality. When installing the protective plate, the positioning rod is aligned with the positioning cavity of the protective plate to position it, ensuring that the threaded cavity of the protective plate is aligned with the connecting screw. Turning the connecting screw into the threaded cavity fixes the connecting screw to the protective plate, thereby fixing the mounting base to the protective plate and completing the installation of the protective plate.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a structural diagram of a detachable anti-collision buffer structure for a cleaning vehicle according to this utility model. Figure 2 This is a longitudinal structural sectional view of a detachable anti-collision buffer structure for a cleaning vehicle according to this utility model. Figure 3 This is a transverse structural cross-sectional view of a detachable anti-collision buffer structure for a cleaning vehicle according to this utility model.

[0019] This utility model provides a detachable anti-collision buffer structure for a cleaning vehicle, including a side brush body 100 and an anti-collision component; the anti-collision component includes an elastic rod, a mounting base 210, a protective plate 220, a connecting screw 230, a positioning rod 240, a rotating plate 260 and a rubber sheet 310, and the elastic rod includes a fixed outer rod 270, a spring 280 and a movable inner rod 290;

[0020] In this specific embodiment, the elastic rod is disposed on the side of the side brush body 100, and the mounting base 210 is fixedly connected to the elastic rod. The mounting base 210 is located at the end of the elastic rod away from the side brush body 100. One end of the connecting screw 230 is rotatably connected to the mounting base 210. The protective plate 220 is provided with a threaded cavity 221 and a positioning cavity 222 spaced apart. The other end of the connecting screw 230 is threadedly connected to the protective plate 220, and the end of the connecting screw 230 away from the mounting base 210 is located inside the threaded cavity 221. One end of the positioning rod 240 is fixedly connected to the mounting base 210, and the other end of the positioning rod 240 is located inside the positioning cavity 222. The elastic rod is elastic and can extend and retract. The mounting base 210 is used to install the protective plate 220, the connecting screw 230 is used to connect the protective plate 220 and the mounting base 210, and the positioning rod 240 is used to position the protective plate 220. When the side brush body 100 is impacted, the protective plate 220 is compressed, which in turn compresses the elastic rod. The elastic rod then contracts, buffering the impact and thus protecting the side brush body 100 by cushioning and reducing shock. When the protective plate 220 is damaged and needs to be disassembled for repair, the connecting screw 230 can be turned to disengage it from the threaded cavity 221, allowing the protective plate 220 to be pulled out for easy repair and replacement. This makes the repair and replacement of the protective plate 220 very convenient, thereby improving its practicality. When installing the protective plate 220, align the positioning rod 240 with the positioning cavity 222 of the protective plate 220 to position the protective plate 220, so that the threaded cavity 221 of the protective plate 220 can be aligned with the connecting screw 230. Tighten the connecting screw 230 to screw it into the threaded cavity 221, thereby fixing the connecting screw 230 to the protective plate 220, and then fixing the mounting base 210 to the protective plate 220 to complete the installation of the protective plate 220.

[0021] Furthermore, a connecting ring 250 is provided at the end of the connecting screw 230, and the mounting base 210 has an annular groove adapted to the connecting ring 250, with the connecting ring 250 located inside the annular groove. The connecting ring 250 is rotatable within the annular groove, and the connecting ring 250 and the annular groove cooperate to achieve a rotatable connection between the connecting screw 230 and the mounting base 210.

[0022] Specifically, the rotating plate 260 is fixedly connected to the connecting ring 250, and the rotating plate 260 is located on the outside of the connecting ring 250. The rotating plate 260 is provided on the outside of the connecting ring 250, allowing the connecting ring 250 to rotate, thereby facilitating the rotation of the connecting screw 230.

[0023] Wherein, one end of the fixed outer rod 270 is fixedly connected to the side brush body 100, one end of the movable inner rod 290 is slidably connected to the fixed outer rod 270, the movable inner rod 290 is located at the end of the fixed outer rod 270 away from the side brush body 100, both ends of the spring 280 are fixedly connected to the fixed outer rod 270 and the movable inner rod 290 respectively, the spring 280 is located inside the fixed outer rod 270, and the mounting base 210 is fixedly connected to the movable inner rod 290, the mounting base 210 is located at the end of the movable inner rod 290 away from the fixed outer rod 270. The movable inner rod 290 can slide relative to the fixed outer rod 270. The spring 280 supports the movable inner rod 290. When the protective plate 220 is squeezed, the movable inner rod 290 moves inward to the fixed outer rod 270, thereby compressing the spring 280. The spring 280 generates a restoring force under pressure, thereby offsetting part of the impact force and buffering the impact.

[0024] In addition, the rubber sheet 310 is fixedly connected to the protective plate 220, and the rubber sheet 310 is located on the side of the protective plate 220 away from the mounting base 210. The rubber sheet 310 is provided on the side of the protective plate 220, and the rubber sheet 310 is elastic to protect the protective plate 220.

[0025] When replacing the protective plate 220 using the detachable anti-collision buffer structure of the cleaning cart, the connecting screw 230 can be turned by rotating the rotating piece 260 to disengage it from the threaded cavity 221, allowing the protective plate 220 to be pulled out for maintenance and replacement. This makes maintenance and replacement of the protective plate 220 very convenient, thereby improving its practicality. When installing the protective plate 220, the positioning rod 240 is aligned with the positioning cavity 222 of the protective plate 220 to position the protective plate 220, so that the threaded cavity 221 of the protective plate 220 is aligned with the connecting screw 230. Turning the connecting screw 230 into the threaded cavity 221 fixes the connecting screw 230 to the protective plate 220, thereby fixing the mounting base 210 to the protective plate 220, thus completing the installation of the protective plate 220.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
