Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and more specifically, to a three-sided bent foot guard. Background Technology

[0002] According to the new elevator safety technical specifications, the elevator car foot guards should have the following strength requirements: at the landing, when a force of 300N is applied to a circular or square area of ​​5cm² below the vertical part of the foot guard, its elastic deformation should not exceed 35mm; the regulations also specify the dimensions of the foot guards: the vertical part of the car foot guard should be no less than 0.75m in height and no less than the width of the landing entrance.

[0003] Based on the above, the inventors have discovered that existing foot guards are typically made from a single large, thin iron plate with reinforcing ribs on the back. The upper part of the foot guard is fixed to the car sill, and the reinforcing ribs on the back are secured by diagonal braces, with the other end of the braces fixed to the bottom of the car, forming a triangular load-bearing structure. Because the foot guards themselves are mostly made of thin galvanized steel and are quite tall, even increasing the thickness of the plate makes it difficult to meet strength requirements and increases costs. Furthermore, the original foot guard's connection holes to the bracket are oblong holes, requiring complete removal of bolts for both installation and removal, making fasteners prone to loss during on-site installation. Therefore, in view of these issues, the inventors have researched and improved the existing structure, providing a three-sided bent foot guard to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a three-sided bending foot plate. It can significantly improve the rigidity of the foot plate by adding side bending parts and bottom bending parts at both ends of the connecting main board and with the help of reinforcing ribs. This reduces the deformation under large external forces, thereby reducing the thickness and cost. At the same time, the connection hole between the main board and the foot plate frame is designed as a gourd hole, which reduces the risk of losing bolts on site.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A three-sided bending foot guard includes a connecting main board. Both ends of one side of the connecting main board are bent to form side bending portions, and the bottom of one side of the connecting main board is bent to form a bottom bending portion. A reinforcing rib is horizontally fixed in the middle of one side of the connecting main board, and the two ends of the reinforcing rib are fixedly connected to the inner side of the corresponding side bending portion. Multiple connection holes are provided at the top of one side of the connecting main board.

[0009] Furthermore, the reinforcing ribs are fixedly connected to the main board and the side bend via multiple rivets.

[0010] Furthermore, the connecting hole is a gourd-shaped hole.

[0011] Furthermore, the side of the reinforcing rib furthest from the motherboard is fixedly connected to two diagonal braces by bolts, and the two diagonal braces are symmetrically arranged.

[0012] Furthermore, the top of the connecting motherboard side is fixedly connected to the pedal bracket through connecting holes and screws.

[0013] Furthermore, the top of the pedal frame is fixedly connected to the car sill by multiple bolts.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, by adding side bends and bottom bends at both ends of the main board and at the bottom respectively, the overall rigidity of the foot protector can be significantly improved, so that its deformation under large external force is greatly reduced. At the same time, reinforcing ribs are added and used as fixing points for diagonal bracing. The reinforcing ribs connect the side bends at both ends of the foot protector, further improving the rigidity of the foot protector.

[0017] (2) In this solution, the rigidity is improved by bending the three sides of the connecting motherboard, so the thickness of the foot plate can be reduced, thereby effectively reducing the cost. At the same time, the connection hole between the connecting motherboard and the foot plate frame is designed as a gourd hole, which reduces the risk of losing bolts on site.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figures 1-4 A three-sided bending foot guard includes a connecting main board 1, with side bending portions 2 at both ends of one side of the connecting main board 1, a bottom bending portion 3 at the bottom of one side of the connecting main board 1, a reinforcing rib 4 horizontally fixed in the middle of one side of the connecting main board 1, with both ends of the reinforcing rib 4 fixedly connected to the inner side of the corresponding side bending portion 2, and multiple connecting holes 5 opened at the top of one side of the connecting main board 1.

[0034] See Figure 4 The reinforcing rib 4 is fixedly connected to the main board 1 and the side bend 2 by multiple rivets.

[0035] See Figure 4 Connecting hole 5 is a gourd hole.

[0036] See Figure 3 The reinforcing rib 4 is fixedly connected to two diagonal braces 6 by bolts on the side away from the main board 1, and the two diagonal braces 6 are symmetrically arranged.

[0037] See Figure 3 The top side of the main board 1 is fixedly connected to the pedal frame 7 through the connection hole 5 and screws.

[0038] See Figure 3 The top of the pedal frame 7 is fixedly connected to the car sill 8 by multiple bolts.

[0039] When in use: bend the two ends and the bottom of the main board 1 to form two symmetrical side bends 2 and bottom bends 3. This can significantly improve the overall rigidity of the foot guard and greatly reduce its deformation under large external forces. At the same time, a reinforcing rib 4 is added and used as the fixing point of the diagonal brace 6. The reinforcing rib 4 connects the side bends 2 at both ends of the foot guard, further improving the rigidity of the foot guard.

[0040] Because the rigidity of the connecting motherboard 1 is increased by bending it on three sides, the thickness of the foot plate can be reduced, thereby effectively reducing the cost. At the same time, the connection hole 5 between the connecting motherboard 1 and the footplate 7 is designed as a gourd hole, which reduces the risk of losing bolts on site.
