Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing elevator parts, in particular to an anti-collision elevator chute sill. Background Art

[0002] With the development of the elevator industry, national standards have increasingly higher requirements for the safety of elevator use. The strength requirements of the middle door panels of the door system produced are of paramount importance. The 7.2 Strength of Doors and Their Frames in the Safety Specifications for Elevator Manufacturing and Installation (GB7588-2003) stipulates that the floor door and its door lock should have such mechanical strength when locked: that is, when a force of 300N is applied vertically to any position on any surface of the floor door and evenly distributed on a circular or square area of ​​5 square centimeters, it should be able to:

[0003] aNo permanent deformation;

[0004] b. Elastic deformation is not greater than 15 mm;

[0005] c During and after the test, the safety function of the door is not affected.

[0006] Therefore, in view of the standard, the manufacturing company has made a series of improvements to meet the national standard requirements, including the strength of the door panel itself, the upper retaining device, the lower retaining device, etc. The lower retaining device consists of a sill and a door slider (installed on the elevator car door), that is, the elevator sill is compatible with the elevator car door for guidance and support. Since the aluminum sill has good plasticity, it can be directly molded with a barb, and the corresponding door slider is also made into a hook type. When impacted, the door slider hooks with the sill, thereby meeting the impact requirements (the door panel does not separate from the retaining device). This practice is more common in the market.

[0007] For example, Chinese Patent Publication (Announcement) No.: CN104909250A, Patent Title: A Type of Anti-slip Sill Assembly with a Barb, which discloses the following technical solution: “

[0004] The technical solution of the present invention is: a type of anti-slip sill assembly with a barb, comprising an aluminum bracket, a sill bracket, a low square neck bolt assembly and a fixing bolt assembly, wherein the aluminum bracket comprises a first pedal, a bracket assembly and a second pedal which are sequentially connected, wherein both ends of the first pedal and the second pedal are respectively provided with downwardly protruding embedding grooves, wherein the sill bracket is provided in a U-shaped structure, wherein the embedding grooves are embedded in both side ends of the sill bracket, wherein the bracket assembly comprises an upper cavity and a lower cavity, wherein the top of the upper cavity is provided with an opening structure, wherein both ends of the opening structure are respectively connected to the first pedal and the second pedal, wherein the second pedal is provided with a reversely protruding arrangement in the upper cavity and a barb which is obliquely downwardly arranged”, which solves the technical problem of “

[0010] The present invention is a type of anti-slip sill assembly with a barb…, which ensures that when someone hits the door panel, the slider will not jump out of the sill groove to cause the door panel to tilt.” It is also achieved by "the second pedal being reversely protruding in the upper cavity and having a barb obliquely downwardly arranged", and the material is aluminum profile.

[0008] This conventional barb made of aluminum profiles will hook the door slider and the sill when impacted. Since the strength of aluminum profiles is lower than that of materials such as steel, there is room for improvement in order to better meet the needs of national standards. Summary of the invention

[0009] The utility model aims to provide an anti-collision elevator chute sill to solve the problems raised in the above-mentioned background technology.

[0010] In order to solve the above technical problems, the utility model is achieved through the following technical measures: an anti-collision inclined groove sill, which includes a sill body made of steel plate, on which two identical inclined grooves are arranged, and the cross-section of the inclined groove is an inclined parallelogram with an inclination angle of A, and the range of angle A is between 75 degrees and 85 degrees; the inclined groove can accommodate a door slider on a door panel, and the front end of the door slider is integrally provided with a hook foot portion, and the hook foot portion is a bent shape with a bending angle of B, and the range of angle B is between 75 degrees and 85 degrees.

[0011] Compared with the prior art, the utility model has the advantages that: by setting two identical inclined grooves on the sill body made of steel plate, and cooperating with the door slider on the door panel, when an external force hits the door panel, the door slider on the door panel can hook the inclination of the inclined groove through the hook foot part thereon, thereby preventing the door panel from falling out. Compared with the traditional aluminum sill, the sill body made of steel plate has higher strength than the aluminum sill.

[0012] As an improvement of the utility model, the sill body is a steel plate grooved sill. The purpose of selecting this design is that the steel plate grooved sill is processed by cutting to cut two long inclined grooves on a whole piece of steel, and this structure can ensure sufficient strength of the sill.

[0013] As an improvement of the utility model, the sill body is a steel plate bent sill. The purpose of selecting this design is that the steel plate bent sill is processed by bending, and two long inclined grooves are pressed out on a whole thin steel plate through a bending device. This structure can ensure the strength of the sill, and the production cost is lower than that of the steel plate grooved sill.

[0014] As an improvement of the utility model, the angle A is 80 degrees. The purpose of selecting this design is: if the angle A is too large, it will be close to a right angle and will not play the role of hooking and blocking; if the angle A is too small, the effective distance of the inclined groove will be narrowed, and the door slider will scrape the two sides of the inclined groove.

[0015] As an improvement of the present invention, angle B = angle A. The purpose of selecting this design is that when an external force hits the door panel, the hook foot on the door slider can completely match the inclination angle of the inclined groove, so that the force can be more fully received.
