Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cleaning appliance, especially an escalator cleaning brush structure. BACKGROUND

[0002] The patent document with the patent authorization announcement number CN209346265U discloses a technical scheme named "an escalator cleaning brush", and the technical scheme comprises the following technical features: a wooden board, a mounting groove, an opening, a fixed block, a plate brush group, a plate brush, a mounting plate, brush hair, a sliding block, a supporting rod, a connecting rod one, a connecting rod two and an antiskid sleeve.When the plate brush is used to clean the steps of the escalator, the brush hair on the plate brush is pressed on the top surface of the steps of the escalator, and the escalator is operated so that each step of the escalator passes through the brush hair to achieve the cleaning purpose. Since the top surface of the step has a plurality of parallel strip-shaped grooves, and it is difficult to make the brush hair evenly distributed on the top surface of the step and in the strip-shaped grooves during the placement of the plate brush, the reaction force of the step on the escalator cleaning brush is uneven, which easily causes the escalator cleaning brush to slide irregularly relative to the step, and further easily causes the brush hair to be unable to evenly and stably be in the strip-shaped grooves and on the top surface of the step, which limits the cleaning effect of the escalator cleaning brush on the step, especially the cleaning effect on the strip-shaped grooves (the irregular horizontal sliding of the escalator cleaning brush causes the brush hair to bend and leave the strip-shaped grooves), which greatly affects the cleaning quality of the escalator cleaning brush. Although the restriction of the escalator cleaning brush can be increased by stepping on the wooden board during the cleaning process, the stepping force cannot be too large because the escalator is in operation during the cleaning process, so the restriction of the cleaning brush by the stepping force is limited, and the escalator cleaning brush still easily slides irregularly relative to the step, which still easily causes a low cleaning quality. Therefore, it is necessary to redesign the structure of the escalator cleaning brush. CONTENT OF THE UTILITY MODEL

[0025] As Figures 1 to 6 shown, the utility model discloses an automatic escalator cleaning brush structure, including cleaning brush body 1, at least one limit block 2, wherein the bottom surface of limit block 2 is provided with the snap tooth part that can slide and buckle with the top of the pedal, and the limit block 2 is set up on the cleaning brush body 1.

[0026] The automatic escalator cleaning brush structure has at least one limiting block 2, and the bottom surface of the limiting block 2 is provided with a clamping tooth part 21 capable of being slidably clamped with the top of the step. The limiting block 2 is arranged on the cleaning brush body 1. In this way, when cleaning the step of the automatic escalator, the clamping tooth part 21 can be slidably clamped on the top of the step to avoid irregular horizontal sliding of the cleaning brush body 1. With the operation of the step, the top of the step can guide and comb the cleaning brush body 1, so that the cleaning brush body 1 is uniformly and stably distributed on the top surface of the step and / or in the strip-shaped groove, thereby stably and reliably cleaning the top surface of the step and the strip-shaped groove, and the cleaning of the top of the step by the cleaning brush body 1 is more comprehensive and effective, which greatly improves the cleaning quality of the step of the automatic escalator.

[0027] Because the top surface of the step of the automatic escalator is provided with a plurality of parallel strip-shaped grooves, the length direction of the strip-shaped grooves is the same as the moving direction of the step, and the strip-shaped grooves horizontally penetrate the top of the step, so that the top of the step is tooth-shaped, which meets the sliding clamping requirement of the clamping tooth part 21. When the clamping tooth part 21 is clamped on the top of the step, the transverse sliding of the cleaning brush body 1 is limited, and the cleaning brush body 1 can only slide along the length direction of the strip-shaped groove relative to the step. During this process, the top surface of the step can generate uniform and stable friction force on the cleaning brush body 1, thereby guiding and combing the cleaning brush body 1, and the cleaning brush body 1 is uniformly and stably distributed on the top surface of the step and / or in the strip-shaped groove.

[0028] In this way, during the cleaning process, with the operation of the step and the limitation of the clamping tooth part 21, the top of the step can only generate stable friction force on the cleaning brush body 1, which can uniformly guide and comb the cleaning brush body 1, so that the cleaning brush body 1 is naturally, uniformly and stably distributed on the top surface of the step and in the strip-shaped groove, thereby achieving high cleaning quality of the step of the automatic escalator.

[0029] As shown in Figure 1 As shown in Figure 2 The bottom surface of the clamping tooth part 21 is higher than the bottom surface of the cleaning brush body 1. In this way, the clamping tooth part 21 does not affect the cleaning of the strip-shaped groove on the step by the cleaning brush body 1, thereby meeting the actual use requirement.

[0030] As shown in Figure 3As shown, the number of the limiting blocks 2 is more than two, each limiting block 2 is arranged transversely side by side, and the limiting blocks 2 can slide transversely on the cleaning brush body 1; the limiting blocks 2 are provided with locking members 3 which can lock the limiting blocks 2 on the cleaning brush body 1. In this way, the purpose of adjusting the distance between the limiting blocks 2 can be achieved, so that the limiting blocks 2 can be slidably buckled on the tread with different top bar groove distances, thereby helping to improve the application range of the escalator cleaning brush structure. Through the locking of the locking members 3, the limiting blocks 2 can be stably positioned on the cleaning brush body 1, which can ensure that the escalator cleaning brush structure has high reliability.

[0031] As shown in Figure 3 , two limiting blocks 2 can be used in actual manufacturing process. This not only has small manufacturing difficulty and cost, but also facilitates quick matching on different treads, which can make the escalator cleaning brush structure have very high applicability.

[0032] As shown in Figure 3 , the front wall or the rear wall of the cleaning brush body 1 is provided with a transversely extending T-shaped guide groove 11, and the limiting blocks 2 are slidably embedded in the T-shaped guide groove 11. This not only meets the demand of transversely adjusting the position of the limiting blocks 2, but also has a very stable and reliable limiting effect on the limiting blocks 2, thereby facilitating to improve the accuracy and stability of the installation and positioning of the limiting blocks 2, and further helping to further improve the reliability and applicability of the escalator cleaning brush structure.

[0033] As shown in Figure 3 , Figure 5 and Figure 6 , one end of the limiting block 2 towards the cleaning brush body 1 is a T-shaped protrusion 22 matched with the T-shaped guide groove 11, which can facilitate the stable and reliable transversely reciprocating sliding installation of the limiting block 2 on the T-shaped guide groove 11, thereby meeting the actual assembly and use requirements.

[0034] As shown in Figure 3 , the locking member 3 is a locking screw screwed on the limiting block 2, and the inner end of the locking member 3 can be tightly pressed on the groove bottom of the T-shaped guide groove 11. In this way, the locking of the limiting block 2 can be quickly and stably realized by tightly pressing the locking member 3 on the groove bottom of the T-shaped guide groove 11, which helps to improve the convenience and stability of the locking.

[0035] As shown in Figure 3 and Figure 6As shown in the drawings, the inner wall of the limiting block 2 is embedded with a positioning nut 23, and the locking piece 3 is screwed on the positioning nut 23. The outer circumferential surface of the screw cap end of the locking piece 3 is provided with a strip-shaped anti-skid surface 31 or a meshed anti-skid surface (not shown in the drawings). In this way, the limiting block 2 can be made by hard plastic forming, and the positioning nut 23 can provide very reliable locking for the screwing of the locking piece 3, which not only facilitates the manufacturing of relevant components, but also ensures that the locking is very stable and reliable; through the provision of the strip-shaped anti-skid surface 31 or the meshed anti-skid surface, slipping can be avoided when the locking piece 3 is rotated by hand, which can improve the convenience of adjustment; thereby helping to further improve the applicability of the escalator cleaning brush structure.

[0036] As shown in the drawings, Figures 1 to 3 , Figure 5 and Figure 6 As shown in the drawings, the limiting block 2 includes a vertical block body 24 and a horizontal block body 25, the lower end of the vertical block body 24 is connected to the end of the horizontal block body 25, the vertical block body 24 is arranged on the front wall or the rear wall of the cleaning brush body 1, and the hook tooth part 21 is located on the bottom surface of the horizontal block body 25. Such a limiting block 2 is very simple and reliable, which not only facilitates the forming and manufacturing of the limiting block 2, but also facilitates providing sufficient connection for the connection of the limiting block 2 and the cleaning brush body 1, and facilitates adopting a large-volume hook tooth part 21, thereby facilitating the manufacturing of a more reliable limiting block 2, and further helping to further improve the reliability and applicability of the escalator cleaning brush structure.

[0037] As shown in the drawings, Figure 3 , Figure 5 and Figure 6 As shown in the drawings, the T-shaped protrusion 22 is located on the side wall of the vertical block body 24 away from the horizontal block body 25, the locking piece 3 is arranged on the vertical block body 24, the side wall of the vertical block body 24 towards the top surface of the horizontal block body 25 is connected to the top surface of the horizontal block body 25 through a circular arc transition, and the T-shaped protrusion 22, the vertical block body 24, the horizontal block body 25 and the hook tooth part 21 are an integrally formed structure. In this way, the limiting block 2 has a very stable and reliable structure, thereby helping to further improve the reliability and applicability of the escalator cleaning brush structure.

[0038] As shown in the drawings, Figures 1 to 4 As shown in the drawings, the cleaning brush body 1 includes a positioning shell 12 and a brush plate 13, the bottom surface of the positioning shell 12 is provided with a positioning groove 14, the brush plate 13 is detachably embedded in the positioning groove 14, and the limiting block 2 is arranged on the positioning shell 12. Such a cleaning brush body 1 is very simple and reliable, which not only facilitates manufacturing, but also plays an accurate and stable positioning role on the brush plate 13 through the positioning groove 14 on the positioning shell 12, thereby facilitating to play a stable and reliable cleaning effect, and further helping to further improve the reliability and applicability of the escalator cleaning brush structure.

[0039] As Figure 2 With Figure 4 As shown in the figure, one of the front and rear ends of the positioning groove 14 penetrates through the corresponding outer wall of the positioning shell 12. In this way, not only can the brush plate 13 be stably positioned, but also the brush plate 13 can be conveniently disassembled and assembled, thereby helping to improve the convenience of disassembling and assembling the brush plate 13, and further helping to improve the applicability of the escalator cleaning brush structure.

[0040] As Figure 3 , Figure 4 , Figure 7 With Figure 8 As shown in the figure, the positioning shell 12 includes a main shell 121 and two side covers 122. The main shell 121 includes vertical slats 1211 and horizontal slats 1212. The length direction of the vertical slats 1211 and the horizontal slats 1212 extends horizontally, and the upper side of the vertical slats 1211 is connected to the front side or the rear side of the horizontal slats 1212. The two side covers 122 are respectively covered on the left and right ends of the horizontal slats 1212, and the two side covers 122 are also covered on the left and right ends of the vertical slats 1211. The inner wall of the side cover 122 is provided with a reinforcing convex column 1221, and the reinforcing convex column 1221 is embedded on the horizontal slat 1212. The bottom surface of the horizontal slat 1212 penetrates a locking screw 123, and the threaded end of the locking screw 123 is upwardly screwed with the reinforcing convex column 1221. The vertical slats 1211, the horizontal slats 1212, and the two side covers 122 together form the positioning groove 14. The T-shaped guide groove 11 is formed on the outer wall of the vertical slat 1211 away from the positioning groove 14. In this way, not only can the manufacturing and assembly be facilitated, but also the assembled positioning shell 12 can have high reliability.

[0041] As Figure 7 As shown in the figure, the vertical slats 1211 and the horizontal slats 1212 are an integral profile structure, and the T-shaped guide groove 11 is integrally formed. This not only facilitates batch manufacturing, but also ensures that the main shell 121 has high structural strength, thereby further improving the reliability of the escalator cleaning brush structure.

[0042] As Figure 4 As shown in the figure, a magic tape assembly 4 is arranged between the brush plate 13 and the groove bottom of the positioning groove 14, which can adhere and position the brush plate 13 in the positioning groove 14. In this way, the convenience of disassembling and assembling the brush plate 13 can be greatly improved, thereby further improving the convenience of disassembling and maintaining the brush plate 13.

[0043] As Figure 3 With Figure 4As shown, the magic tape assembly 4 includes at least one magic tape hook plate 41, at least one magic tape hair plate 42, the bottom surface of the horizontal plate strip 1212 is provided with at least one transversely penetrating T-shaped clamping slot 1213, the number of T-shaped clamping slots 1213 is equal to the number of magic tape hook plates 41, the magic tape hook plate 41 is embedded in the T-shaped clamping slot 1213, and the hook surface of the magic tape hook plate 41 protrudes out of the T-shaped clamping slot 1213, the magic tape hair plate 42 is fixedly attached to the top surface of the brush plate 13, and the magic tape hair plate 42 is attached to the magic tape hook plate 41. This not only facilitates the stable and reliable attachment and positioning requirements of the brush plate 13, but also meets the disassembly and assembly requirements of the brush plate 13.

[0044] As shown in Figures 1 to 4 , Figure 9 , the top surface of the cleaning brush body 1 is provided with a rearward or forward inclined sleeve clamping pipe 5, the upper end of the sleeve clamping pipe 5 is provided with a plurality of annularly arranged sleeve clamping springs 51, the sleeve clamping pipe 5 is threadedly sleeved with a locking pipe 6, and the inner wall of the locking pipe 6 can press against the sleeve clamping springs 51, and when the locking pipe 6 is tightened, the sleeve clamping springs 51 can be brought together to achieve sleeve clamping. The inner hole of the sleeve clamping pipe 5 and the inner hole of the locking pipe 6 can accommodate the insertion of a hand-held rod, so that when the hand-held rod (not shown in the figure) is inserted into the inner hole of the sleeve clamping pipe 5 and the inner hole of the locking pipe 6, the sleeve clamping springs 51 can be clamped on the hand-held rod by tightening the locking pipe 6, which not only facilitates the assembly and disassembly of the hand-held rod, but also ensures that the installation and positioning of the hand-held rod is very stable and reliable. After the hand-held rod is installed, it can be in an inclined state, which can further facilitate user operation, thereby improving the convenience of cleaning.
