Description

Technical Field

[0001] The utility model relates to the field of elevator equipment, in particular to a heavy-duty three-opening sill. Background Art

[0002] An elevator sill is a metal pedal component used under an elevator landing door. By installing the sill, the opening and closing route of the landing door can be standardized, the shaking of the elevator door can be reduced, and the abnormal noise during the opening and closing of the elevator door can be reduced. The commonly used sills at present are generally for elevators with opposite-opening doors. However, in some special environments, the opening space for the elevator installation position is limited. In this case, only a three-opening door solution can be adopted. In the case of a three-opening door, the single-slot sill commonly used for opposite-opening doors is difficult to meet the installation requirements. Summary of the Utility Model

[0004] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a heavy-duty three-opening sill, the heavy-duty three-opening sill includes: an outer door slot, a middle door slot and an inner door slot. The outer door slot, the middle door slot and the inner door slot have the same specifications. An outer partition platform is arranged between the outer door slot and the middle door slot, and an inner partition platform is arranged between the middle door slot and the inner door slot. The top end of the outer side wall of the outer door slot is vertically folded outward to form an outer sill surface, and the top end of the inner side wall of the inner door slot is vertically folded inward to form an inner sill surface. The outer sill surface, the inner sill surface and the top table surfaces of the outer partition platform and the inner partition platform are at the same height. A buffer cavity is arranged inside the inner partition platform, and a bolt fastening groove is opened at the bottom of the buffer cavity. The outer partition platform and the inner partition platform have the same structure.

[0005] In a preferred embodiment of the utility model, a partition board is arranged in the middle of the buffer cavity inside the inner partition platform to divide the buffer cavity inside the inner partition platform into an inner platform top cavity and an inner bolt fastening cavity. A partition board is also arranged at the same position inside the outer partition platform to divide the buffer cavity inside the outer partition platform into an outer platform top cavity and an outer bolt fastening cavity.

[0006] In a preferred embodiment of the utility model, friction lines are arranged on the top table surfaces of the outer sill surface, the inner sill surface, the inner partition platform and the outer partition platform.

[0007] In a preferred embodiment of the utility model, the width of the outer sill surface is not less than the width of the notch of the outer door slot, and the width of the inner sill surface is the same as the width of the outer sill surface.

[0008] In a preferred embodiment of the utility model, the width of the top table surface of the inner partition platform is 1.5 to 2 times the width of the notch of the inner door slot, and the width of the top table surface of the outer partition platform is the same as the width of the top table surface of the inner partition platform.

[0015] The following elaborates in detail on the preferred embodiments of the present utility model with reference to the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0016] Please refer to Figure 1 , the embodiments of the present utility model include:

[0017] A heavy-duty triple-opening sill, the heavy-duty triple-opening sill is integrally formed by aluminum alloy, and the structure of the heavy-duty triple-opening sill includes: an outer door slot 1, a middle door slot 2, and an inner door slot 3. The outer door slot 1, the middle door slot 2, and the inner door slot 3 have the same specifications. An outer partition platform 6 is provided between the outer door slot 1 and the middle door slot 2, and an inner partition platform 7 is provided between the middle door slot 2 and the inner door slot 3. The top end of the outer side wall of the outer door slot 1 is vertically folded outward to form an outer sill surface 4, and the top end of the inner side wall of the inner door slot 3 is vertically folded inward to form an inner sill surface 5. The outer sill surface 4, the inner sill surface 5, and the top surfaces of the outer partition platform 6 and the inner partition platform 7 are at the same height. A buffer cavity is provided inside the inner partition platform 7, and a bolt slot is opened at the bottom of the buffer cavity. The outer partition platform 6 and the inner partition platform 7 have the same structure.

[0018] A partition is provided in the middle of the buffer cavity inside the inner partition table 7, dividing the buffer cavity inside the inner partition table 7 into an inner table top cavity 701 and an inner bolt fastening cavity 702. A partition is also provided at the same position inside the outer partition table 6, dividing the buffer cavity inside the outer partition table 6 into an outer table top cavity 601 and an outer bolt fastening cavity 602. By providing a partition in the middle of the buffer cavity, on the one hand, the overall strength can be improved on the basis of ensuring the buffering performance of the inner partition table 7 and the outer partition table 6, and on the other hand, the moving space of the fastening bolts can be restricted when installing the fastening bolts, preventing the fastening bolts from falling into the buffer cavity and affecting the installation efficiency.

[0019] Friction lines 8 are provided on the top surfaces of the outer threshold surface 4, the inner threshold surface 5, the inner partition table 7, and the outer partition table 6. All the friction lines 8 are concave lines. By providing the friction lines 8, it can effectively prevent the soles of the feet of the personnel using the elevator from slipping when passing through.

[0020] The width of the outer threshold surface 4 is not less than the notch width of the outer door groove 1, and the width of the inner threshold surface 5 is the same as the width of the outer threshold surface 4. The width of the top surface of the inner partition table 7 is 1.5 to 2 times the notch width of the inner door groove 3, and the width of the top surface of the outer partition table 7 is the same as the width of the top surface of the inner partition table 6. The actual designed widths of the inner threshold surface 5 and the outer threshold surface 4 are generally 12 mm, and the designed notch widths of the outer door groove 1, the inner door groove 3, and the middle door groove 2 are equal to the width of the inner threshold surface 5, which is also 12 mm, while the designed widths of the top surfaces of the inner partition table 7 and the outer partition table 6 are 24 mm. The reason for such a design is that if the widths of the outer threshold surface 4 and the inner threshold surface 5 are too small, the installation is unstable, so they are generally the same as or slightly larger than the width of the door groove. The widths of the top surfaces of the inner partition table 7 and the outer partition table 6 are determined by the width of the connection position between the door bodies. If the width of the connection position between the door bodies is too small, the door bodies are prone to rubbing against each other, affecting the opening speed, and if the width is too large, gaps are likely to occur. Therefore, in practice, it is generally 1.5 to 2 times the width of the door groove, and the corresponding widths of the top surfaces should also meet the above requirements.

[0021] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
