Description

Technical Field

[0001] The utility model relates to the technical field of sanitation vehicles, in particular to a steel wire brush piece for sanitation vehicles. Background Art

[0002] As the core component of the sanitation vehicle's sweeper, the wire brush is responsible for cleaning road debris. Traditional wire brush designs typically use multiple strands of steel wire fastened to the brush blade via a pressure plate and bolts. This fixing structure has the following drawbacks:

[0003] The wire bundles tend to become scattered during long-term use and vibration, which not only affects the cleaning effect but also increases the difficulty of maintenance. The scattered wire bundles may also damage other parts of the sanitation vehicle, reducing the reliability and service life of the entire vehicle.

[0004] Fastening the wire bundle with a pressure plate and bolts is not only cumbersome to operate but also has low installation efficiency. The bolts tend to loosen easily during long-term use, causing the wire bundle to fall off, which not only affects the normal progress of the cleaning operation, but may also pose a safety hazard to road traffic. Utility Model Content

[0005] The utility model aims to provide a steel wire brush piece for a sanitation vehicle, which is used to improve the reliability of the connection between the steel wire bundle and the brush piece.

[0006] The utility model adopts the following technical solutions: a steel wire brush piece for a sanitation vehicle, comprising a plate and multiple groups of steel wire bundles;

[0007] The plate is provided with an embedding hole that passes through the plate; an annular fastener is installed in the embedding hole, the circumference of the fastener is in contact with the circumference of the inner wall of the embedding hole, and multiple groups of the steel wire bundles are installed in the fastener;

[0008] Wherein, the inner wall of the embedding hole is provided with a plurality of wedge-shaped protrusions;

[0009] One end of the fastener is provided with a plurality of groups of grooves, and a pressure strip is formed between two grooves in each group of grooves;

[0010] When the fastener is installed in the embedding hole, the pressure strip is squeezed by the corresponding wedge-shaped protrusion and bends inward, thereby squeezing the steel wire bundle in the fastener.

[0011] It is further provided that: the plate comprises an integral connecting portion and a mounting portion, and an angle is formed between the connecting portion and the mounting portion; two elongated connecting grooves are provided on the connecting portion; and the embedding hole is provided on the mounting portion.

[0012] The embedding hole is an elongated hole, and the inner walls in both length directions of the embedding hole are provided with evenly distributed wedge-shaped protrusions, and the wedge-shaped protrusions on both sides are arranged in a staggered manner.

[0013] The wedge-shaped protrusion is arranged close to the lower end of the embedding hole, and the wedge-shaped protrusion gradually protrudes from top to bottom.

[0014] The fastener is formed by bending a strip plate, and the butt ends of the fastener are connected by a connecting piece.

[0015] The side surfaces of the butt ends of the fasteners are provided with opposite "convex" shaped recessed grooves, and the two ends of the connector are embedded in the "convex" shaped recessed grooves on both sides.

[0016] The butt end of the fastener is arranged on the short side of the fastener.

[0017] The upper end of the embedding hole penetrating the plate is blocked with a cover plate.

[0018] The periphery of the embedding hole penetrating the plate is connected with a fastening bolt through a thread, and the cap body of the fastening bolt is pressed on the edge of the cover plate.

[0019] The beneficial effects of the present invention are:

[0020] The fasteners are used to bind multiple groups of steel wire bundles into a whole and then fix them to the plate, thus avoiding the problem of the steel wire bundles being easily scattered when fixed separately. When the fasteners are installed in conjunction with the mounting holes, the wedge-shaped protrusions in the mounting holes press against the pressure strips in the fasteners, causing the pressure strips to deform inwards, pressing the steel wire bundles inside and preventing them from falling off. At the same time, this also increases the friction between the fasteners and the plate, preventing the fasteners from loosening. As a whole, a firm connection is achieved among the plate, fasteners and steel wire bundles.

[0021] The fastener is formed by bending a strip plate, which makes the manufacturing of the fastener simpler and lowers the cost; the butt ends of the fastener are connected by a connector, which realizes the initial fixation of the wire bundle and the fastener, facilitating subsequent installation operations.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figure 1 、 Figure 2 As shown, the utility model provides a sanitation vehicle wire brush sheet, which mainly includes a plate 1, a fastener 3 and multiple groups of steel wire bundles 2. The fastener 3 is bound to the ends of the multiple groups of steel wire bundles 2 to form a whole, and then fixed to the plate 1 together.

[0037] Combine Figures 1 to 4 As shown, the panel 1 includes an integral connecting portion 11 and mounting portion 12, which have a 165° bend angle. Mounting portion 12 defines a mounting hole 121 that extends through the panel 1. Connecting portion 11 defines two elongated connecting grooves 111 for connecting to the brush plate of a sanitation vehicle. When the panel 1 is installed, mounting portion 12 has a 15° inclination, allowing the lower end of the steel wire bundle 2 in mounting hole 121 to extend outward.

[0038] Mounting hole 121 is an elongated hole. Wedge-shaped projections 122 are evenly distributed along the inner walls of both lengthwise directions of mounting hole 121. The wedge-shaped projections 122 on either side are staggered and not facing each other. The wedge-shaped projections 122 are located near the lower end of mounting hole 121, with their lower ends flush with the lower end of mounting portion 12. The wedge-shaped projections 122 gradually protrude toward the center of mounting hole 121 from top to bottom, with a section at the lower end of the protruding surface parallel to the inner wall of mounting hole 121.

[0039] Combine Figures 1 to 5 As shown, the fastener 3 is annular. In this embodiment, the fastener 3 is a rectangular shape that matches the mounting hole 121. The fastener 3 is installed in the mounting hole 121, with its circumference aligned with the inner wall of the mounting hole 121. The lower end of the fastener 3 is defined by multiple groups of grooves 31 along its circumference, each group of grooves 31 comprising two grooves. A bead 32 is formed between the grooves 31. The bead 32 can be bent along its upper edge under external force.

[0040] like Figure 1 、 Figure 2 As shown, when installed;

[0041] First, install the upper end of the steel wire bundle 2 into the fastener 3, and then pass the lower end of the steel wire bundle 2 through the embedding hole 121 on the plate 1 until the fastener 3 enters the embedding hole 121;

[0042] Continue to press down the fastener 3, and the pressure strip 32 around the fastener 3 gradually contacts the wedge-shaped protrusion 122 on the inner wall of the embedding hole 121; as the fastener 3 moves downward, the pressure strip 32 gradually bends and deforms inward, thereby squeezing the steel wire bundle 2 in the fastener 3, so that the plate 1, fastener 3, and steel wire bundle 2 are tightly combined together.

[0043] Example 2:

[0044] Based on the above embodiment 1, combined with Figure 5 As shown, the fastener 3 in this embodiment is formed by bending a strip plate, and the butt end of the fastener 3 is set on the short side of the fastener 3. Before the strip plate is bent, a groove 31 is cut or punched out on the side. The butt end of the fastener 3 is connected by a connector 4. The side of the butt end of the fastener 3 is provided with a relative "convex" shaped groove, and the two ends of the connector 4 have thickened portions. After the steel wire bundle 2 is installed on the fastener 3, the butt end of the fastener 3 is pressed together, and then the two ends of the connector 4 are embedded in the "convex" shaped grooves on both sides to achieve the initial fixation of the steel wire bundle 2 and the fastener 3, and finally installed together on the plate 1.

[0045] Example 3:

[0046] Based on the above embodiment 2, combined with Figures 1 to 4As shown, in this embodiment, a cover plate 5 is provided at the upper end of a mounting hole 121 extending through the plate 1. This seals the mounting hole 121 from above, preventing water or dust from entering the fastener 3 and the upper end of the wire bundle 2. Fastening bolts 51 are threadedly connected to the periphery of the mounting hole 121. The caps of the fastening bolts 51 press against the edges of the cover plate 5 to prevent it from falling off.

[0047] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
