Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a cleaning tool for escalators. Background Technology

[0002] Due to their advantages such as high operational intensity and reliable safety, escalators have been widely used in public areas with high traffic, such as hospitals, shopping malls, and subways. The surface of escalators has several grooves, requiring specialized cleaning tools to achieve ideal cleaning results. Those skilled in the art are continuously improving these tools to create superior escalator-specific cleaning equipment.

[0003] The Chinese utility model patent application number 202322906230.1, entitled "A Mop for Escalators," discloses a cleaning sponge with grooves formed on its top and sides. Raised strips that fit the grooves are formed inside and on both sides of the mop head fixing plate. This nested structure of grooves and raised strips allows the cleaning sponge to be mounted on the mop head fixing plate. During use, the cleaning sponge is embedded in the toothed grooves of the escalator steps, and as the steps move forward, the sponge cleans the dirt from the surface of the steps and the toothed grooves. However, this technology has the following technical problems during use: First, cleaning sponges are inherently soft materials with poor structural strength. Grooving them further weakens this structure. During use, the sponge is repeatedly subjected to stress from the friction of the escalator, causing the grooves to tear easily. This weakens the connection between the sponge and the mop head holder, making it less effective at cleaning dirt from the escalator grooves. Furthermore, the cracks in the grooves deepen and lengthen over time, resulting in a shorter lifespan for the sponge and higher operating costs for the mop. Additionally, the mop head holder is typically made of metal, so the metal protrusions can easily scratch the groove walls during sponge installation and removal, further accelerating the sponge's wear and tear.

[0004] Secondly, during use, the mop head fixing plate in this technical solution is a flat structure. During use, the mop head fixing plate cannot provide good support for the cleaning sponge, which makes the connection between the cleaning sponge and the mop head fixing plate subject to greater stress and easy to tear, thereby further accelerating the damage rate of the cleaning sponge.

[0005] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide an escalator brush sponge structure with a longer service life and lower operating costs, as well as a housing structure adapted to it. Utility Model Content

[0006] The purpose of this invention is to solve the aforementioned problems and shortcomings by providing a sponge structure for an escalator brush. This structure features a fixed upper part arranged along the length of the sponge strip, with the vertical height of the fixed upper part exceeding that of the cleaning teeth. The fixed upper part also includes a Velcro closure on its back and anti-slip buckle textured edges at both ends. These features prevent tearing of the sponge strip during installation and use, significantly extending its lifespan and reducing the cost of using the escalator brush. Furthermore, this invention aims to provide a housing structure adapted to the aforementioned sponge structure for escalator brush assembly. This housing, with a front and rear covering edge and two end caps respectively fastened to both ends of the housing and containing an inner cavity, provides excellent support and protection for the sponge strip, further extending its lifespan.

[0007] The technical solution of this utility model is implemented as follows: an escalator brush sponge structure, characterized in that it includes a square sponge strip of high-density polyurethane, which further includes a fixed upper part arranged along its length and a cleaning tooth part integrally formed with the fixed upper part, and the vertical height of the fixed upper part is greater than the vertical height of the cleaning tooth part; the back of the fixed upper part is provided with a Velcro gusset, and anti-slip buckle textures are provided at both ends of the fixed upper part; the cleaning tooth part is composed of a plurality of cleaning straight teeth arranged perpendicular to its length direction on the bottom surface of the fixed upper part, with gaps formed on both sides of each cleaning straight tooth.

[0008] Furthermore, the anti-slip buckle has embossed textures arranged horizontally on both ends of the upper part of the fixing device.

[0009] Furthermore, the front and rear sides of the fixed upper part are flush with the front and rear sides of the cleaning teeth, arranged on the same plane.

[0010] Furthermore, the length and width of the Velcro clasp are the same as the length and width of the back of the fixed upper part.

[0011] To further achieve the objectives of this utility model, a housing structure adapted to the above-mentioned escalator brush sponge structure assembly is characterized by comprising a long strip housing with a front covering edge and a rear covering edge. The bottom surface of the long strip housing forms a concave cavity for accommodating and embedding the square sponge strip. A Velcro hook plate is provided on the bottom of the concave cavity to be bonded to the Velcro board. Two end caps, each having an inner cavity, are respectively fastened to both ends of the long strip housing. The inner cavity is provided with a pin with a screw hole. Corresponding pin holes are provided on both ends of the long strip housing. The end caps are fixed to the ends of the long strip housing by fastening the inner cavity to the ends of the long strip housing, the fitting of the pin and the pin hole, and the screws locked into the screw holes.

[0012] Furthermore, the vertical height of the front covering edge is less than the vertical height of the rear covering edge.

[0013] Furthermore, the end cap is composed of an end panel, a front edge, a rear edge, and a top edge connecting the end panel, the front edge, and the rear edge. The enclosed inner cavity is formed by the end panel, the front edge, the rear edge, and the top edge. The pin is disposed on the bottom surface of the top edge.

[0014] Furthermore, the vertical height of the front bumper edge is less than the vertical height of the rear bumper edge.

[0015] Furthermore, the front bumper edge and the end panel feature an arc-shaped transition design.

[0016] The beneficial effects of this utility model are: Firstly, the escalator brush sponge structure provided by this utility model, during assembly, fixes the rectangular sponge strip in the housing by attaching the Velcro backing plate to the housing. This bonding method does not damage the mechanical strength of the rectangular sponge strip itself. During the installation and removal process, the housing will not damage the rectangular sponge strip itself, thus helping to extend its service life.

[0017] Secondly, by fixing the upper vertical height of the rectangular sponge strip to a height greater than that of the cleaning teeth, most of the rectangular sponge strip is embedded inside the shell, with only a small portion protruding. This creates a large connection area between the rectangular sponge strip and the shell, allowing it to be securely installed and significantly reducing stress on the strip. This extends its lifespan and lowers the cost of using the escalator brush. Simultaneously, it enhances support for the cleaning teeth, enabling them to clean the escalator steps more stably and without damage.

[0018] Furthermore, the anti-slip buckles with raised texture at both ends of the square sponge strip not only further increase the connection area between the square sponge strip and the shell, but also further increase the friction between the square sponge strip and the shell. This allows the square sponge strip to be more firmly fixed to the shell, providing more stable support for the cleaning teeth and further extending its service life.

[0019] Furthermore, this utility model also provides a housing structure adapted to the above-mentioned escalator brush sponge structure assembly. The front and rear covering edges of the elongated housing provide excellent support for the rectangular sponge strip on both the front and rear sides. The end caps fastened to both ends of the elongated housing provide excellent support for the rectangular sponge strip on both the left and right sides. In this way, the elongated housing and the end caps form an all-round wrapping structure for the rectangular sponge strip, which not only further improves the stability of the rectangular sponge strip during use, preventing it from shifting or slipping, but also better cleans dirt on the escalator steps. It also further prevents the rectangular sponge strip from being damaged by external forces, thereby helping to extend its service life and further reduce the cost of using the escalator brush.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 3 , 4As shown, this utility model provides an escalator brush sponge structure. To achieve the purpose proposed by this utility model, it includes: a square sponge strip 1 of high-density polyurethane, which further includes a fixed upper part 11 arranged along its length direction and a cleaning tooth part 12 integrally formed with the fixed upper part 11, and the vertical height of the fixed upper part 11 is greater than the vertical height of the cleaning tooth part 12; the back of the fixed upper part 11 is provided with a Velcro board 2, and anti-slip buckle texture 13 is provided at both ends of the fixed upper part 11; the cleaning tooth part 12 is composed of a plurality of cleaning straight teeth 14 arranged perpendicular to the length direction of the fixed upper part 11 on the bottom surface, and gaps 15 are formed on both sides of each cleaning straight tooth 12.

[0028] Through the above technical solution, the square sponge strip 1 of this utility model is not easily damaged during loading, unloading and use, has a long service life, and greatly reduces the cost of using escalator brushes.

[0029] like Figure 3 , 4 As shown, the anti-slip buckle's raised and recessed texture 13 is horizontally arranged on the end faces of both ends of the fixed upper part 11. This ensures that the cleaning teeth 12 are not damaged during the fabrication of the anti-slip buckle's raised and recessed texture 13, thus reducing the difficulty of processing.

[0030] like Figure 3 , 4 As shown, the front and rear sides of the fixed upper part 11 are flush with the front and rear sides of the cleaning teeth 12, forming the same plane. This makes the overall structure of the square sponge strip 1 simpler. Furthermore, the connection between the fixed upper part 11 and the cleaning teeth 12 is a planar structure, which prevents stress concentration and reduces the likelihood of cracks, thus extending the service life of the square sponge strip 1.

[0031] like Figure 3 As shown, the length and width of the hook and loop fastener 2 are the same as the length and width of the back of the fixed upper part 11. In this way, the entire back of the fixed upper part 11 is covered with hook and loop fastener 2, thereby maximizing the area of ​​the hook and loop fastener 2 and allowing the rectangular sponge strip to be firmly installed on the shell.

[0032] like Figures 1 to 4As shown, this utility model also provides a shell structure adapted to the above-mentioned escalator brush sponge structure assembly. To achieve the purpose proposed by this utility model, it includes: a long shell 3 with a front covering edge 31 and a rear covering edge 32. The bottom surface of the long shell 3 forms a cavity 30 for the square sponge strip 1 to be accommodated and embedded. A hook plate 4 for bonding with the hook and loop fastener 2 is provided on the bottom of the cavity 30; two end caps 5 respectively fastened to both ends of the long shell 3 and having a covering cavity 50. The covering cavity 50 is provided with a pin 501 with a screw hole 502. The two ends of the long shell 3 are correspondingly provided with pin holes 33. The end caps 5 are fixed to the ends of the long shell 3 by the covering cavity 50 fastened to the ends of the long shell 3, the matching of the pin 501 and the pin hole 33, and the screws locked into the screw holes 502.

[0033] In this way, the end cap 5 is firmly fixed to the end of the elongated housing 3 with screws, and together with the elongated housing 3, it covers the fixed upper part 11 of the square sponge strip 1, providing it with all-round protection. During use, the square sponge strip 1 can not only complete the cleaning work very stably, but also be protected from external damage, thereby extending the service life of the square sponge strip 1.

[0034] like Figure 3 , 4 As shown in Figure 5, a T-shaped groove 301 is provided on the top wall of the cavity 30 for the hook and loop fastener 4 to be fitted. The two sides of the hook and loop fastener 4 are thus confined within the limiting grooves 302 on the left and right sides of the T-shaped groove 301. The hook head of the hook and loop fastener 4 protrudes from the opening of the T-shaped groove 301 and adheres to the hook and loop fastener 2. Due to the limiting effect of the limiting grooves 302 on the two sides of the hook and loop fastener 4, the hook and loop fastener 4 is not easily lifted during use, and even with long-term use, it can firmly adhere the rectangular sponge strip 1 to the cavity 30.

[0035] like Figure 3 , 4 As shown in Figure 5, a screw groove 303 for the screw head to be embedded is provided on the top cavity wall of the concave cavity 30. After the screw passes through the pin hole 33 and extends into the pin post 501 to lock, the screw head is embedded in the screw groove 303. In this way, the screw head will not press against the hook and loop fastener plate 2. The hook and loop fastener plate 2 can be bonded to the hook and loop fastener plate 4 very smoothly, ensuring the bonding strength between the two.

[0036] The elongated shell 3 is made of aluminum profile, which can be obtained through a mature extrusion process, making it very convenient to manufacture and helping to control costs.

[0037] like Figure 3 , 4As shown, the vertical height of the front covering edge 31 is less than the vertical height of the rear covering edge 32. Preferably, the vertical height of the front covering edge 31 is less than the vertical height of the fixed upper part 11, so that there is a relatively spacious operating space on the front side of the elongated shell 3 to install the square sponge strip 1 into the cavity 30, making the operation process more convenient; when in use, the front covering edge 31 faces the escalator step, which can also prevent the front covering edge 31 from scraping against the escalator step, improving the safety of using the escalator brush. Preferably, the vertical height of the rear covering edge 32 is equal to the vertical height of the fixed upper part 11, so that when the cleaning teeth 12 are engaged in the tooth groove of the escalator step to clean the escalator, the rear covering edge 32 can provide maximum support to the cleaning teeth 12 by fully supporting the fixed upper part 11, thereby preventing the cleaning teeth 12 from being damaged during use and extending its service life.

[0038] like Figure 3 , 4 As shown in Figures 6 and 7, the end cap 5 is composed of an end panel 51, a front baffle 52, a rear baffle 53, and a top edge 54 connecting the end panel 51, the front baffle 52, and the rear baffle 53. The enclosed inner cavity 50 is formed by the end panel 51, the front baffle 52, the rear baffle 53, and the top edge 54. The pin 501 is disposed on the bottom surface of the top edge 54. When the end cap 5 is assembled with the elongated housing 3, the end panel 51 is fastened to both ends of the elongated housing 3, the front baffle 52 and the rear baffle 53 are fastened to the front enclosed baffle 31 and the rear enclosed baffle 32, respectively, and the top edge 54 is fastened to the top surface of the elongated housing 3, so that the end cap 5 tightly covers the end of the elongated housing 3 and is securely assembled with the elongated housing 3 by screws locked to the pin 501.

[0039] In order to fit snugly at both ends of the long shell 3 and adapt to the front cover edge 31 and the rear cover edge 32, such as Figure 3 , 4 As shown in Figures 6 and 7, the vertical height of the front bumper 52 is also less than the vertical height of the rear bumper 53.

[0040] like Figure 3 , 4 As shown in Figures 6 and 7, the front bumper edge 52 and the end panel 51 have an arc-shaped transition design. This design helps prevent bumps and collisions with the user during use, making it safer.

[0041] To facilitate the installation of the handle, such as Figure 1 , 2 As shown, the top surface of the middle part of the long shell 3 is also provided with a sleeve tube 6 for the handle assembly and a locking tube 7 that is threaded onto the sleeve tube 6.

[0042] like Figure 2 ,3 As shown, to prevent the escalator brush from sliding left and right on the escalator steps during use, a limiting block 8 with a toothed bottom is provided on the rear cover edge 32. In use, the bottom of the limiting block 8 engages with the toothed groove on the escalator step, thus preventing the escalator brush from sliding left and right during cleaning, and ensuring stable and effective cleaning of the steps. The limiting block 8 is slidably fitted onto the rear cover edge 32 via a T-shaped groove 321 provided on the outer wall of the rear cover edge 32. This allows for flexible adjustment of the position of the limiting block 8 during use, ensuring it is precisely engaged in the toothed groove on the escalator step.
