Abstract
Description
Technical Field
[0001] This utility model relates to the field of escalator technology, and in particular to an escalator comb plate. Background Technology
[0002] Escalators are widely used in public places across my country. The comb plate, a crucial safety component located at both ends of the escalator, is a vital part affecting passenger safety during ascent and descent, and serves as a safety protection device. The comb plate meshes with grooves on the steps or treads. During operation, the comb plate is one of the visible components, and its performance impacts the passenger experience. Over long-term operation, mutual wear occurs between the moving steps and the stationary comb plate. This wear increases the clearance, causes localized material loss in both the comb plate and steps, and reduces the thickness of the comb and step teeth, leading to meshing problems and increasing safety risks. Utility Model Content
[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide an escalator comb plate that improves safety performance and enhances passenger experience.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An escalator comb plate includes a main board. The upper surface of the main board has several parallel, spaced anti-slip grooves. The lower surface of the main board has several groove groups, which form several mutually perpendicular ribs on the lower surface of the main board. One end of the main board has an outwardly extending end portion. The upper surface of the end portion transitions to the upper surface of the main board with an arc. The lower surface of the end portion is flat. The angle between the lower surface of the end portion and the main board is 7.5°. Several comb teeth are evenly spaced on the lower surface of the end portion. The upper surface of the comb teeth transitions to the upper surface of the end portion with an arc. The lower surface of the comb teeth is parallel to the lower surface of the end portion, and the distance between them is 10.3 mm.
[0006] Preferably, an arc surface with a radius of 100mm is formed between the upper surface of the outer end, the upper surface of the main board, and the upper surface of the comb teeth.
[0007] Preferably, the width of the comb teeth is 2.8 mm, and the distance between the same part of two adjacent comb teeth is 9.068 mm.
[0008] Preferably, the motherboard is provided with symmetrical countersunk holes, which are located at the intersection of the ribs.
[0009] Preferably, the inner side of the comb teeth is connected to the ribs, and a plurality of recesses are evenly spaced on the lower surface of the outer end, the recesses being located between adjacent comb teeth.
[0010] Preferably, the escalator comb plate is integrally molded from polycarbonate.

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0020] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0021] As attached Figure 1 The diagram shows the escalator comb plate of this utility model, comprising a main plate 1. The upper surface of the main plate 1 has several parallel, spaced anti-slip grooves 2. These grooves 2 are in direct contact with the soles of passengers' shoes and are used to increase the coefficient of friction on the upper surface of the main plate 1, preventing passengers from slipping due to a smooth surface. The lower surface of the main plate 1 has several groove groups 3. These groove groups 3 form several mutually perpendicular ribs 4 on the lower surface of the main plate 1, which not only strengthens the load-bearing capacity of the main plate 1 but also saves material and is aesthetically pleasing.
[0022] As attached Figure 2 As shown, one end of the main board 1 has an outer end portion 5 extending outward. The upper surface of the outer end portion 5 is rounded to the upper surface of the main board 1. The lower surface of the outer end portion 5 is flat. The angle between the lower surface of the outer end portion 5 and the main board 1 is 7.5°. A number of comb teeth 6 are evenly spaced on the lower surface of the outer end portion 5. The upper surface of the comb teeth 6 is rounded to the upper surface of the outer end portion 5. The lower surface of the comb teeth 6 is parallel to the lower surface of the outer end portion 5 and the distance between them is 10.3mm. This allows the comb teeth 6 to cooperate with the grooves on the steps or treads to form a safe distance, preventing the steps from colliding with the comb teeth 6 during operation.
[0023] An arc surface with a radius of 100mm is formed between the upper surface of the outer end 5, the upper surface of the main board 1, and the upper surface of the comb tooth 6 to make the transition smooth and prevent passengers from contacting sharp parts when leaving the escalator, thus ensuring passenger safety.
[0024] The width of the comb tooth 6 is 2.8mm, and the distance between the same part of two adjacent comb teeth 6 is 9.068mm, which matches the spacing between the escalator step teeth.
[0025] The main board 1 has symmetrical countersunk holes 7. Countersunk screws can be used to fix the comb plate to the front edge plate of the ladder step by passing through the countersunk holes 7. The countersunk holes 7 are located at the intersection of the ribs 4. The ribs 4 form a ring of protrusions around the countersunk holes 7, which makes the overall structure more stable and avoids the weakening of structural strength caused by the opening.
[0026] The inner side of the comb tooth 6 is connected to the rib 4, and several recesses 51 are evenly spaced on the lower surface of the outer end 5. The recesses 51 are located between adjacent comb teeth 6. The comb tooth 6, the rib 4 and the recesses 51 form multiple curved cavities, which further improves the strength of the comb tooth 6 and prevents the comb tooth 6 from breaking.
[0027] The escalator comb plate is made of polycarbonate in one piece, which gives the comb plate both strength and toughness, better protecting the escalator operation. Even if there is a collision during the meshing of the steps and the comb plate, it can prevent the escalator from jamming, ensuring passenger safety and improving the riding experience.
[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
