Description

Technical Field

[0001] The utility model relates to the technical field of connection brackets, in particular to a landing sill bracket for an elevator door. Background Art

[0002] A landing sill is a grooved metal pedal for entering or exiting a car at the entrance of an elevator car or landing door. The landing sill assembly is an important part of the structure of an elevator or the like. The landing sill assembly ensures the normal operation of the landing door opening and closing by fixing the landing sill. Among them, a bracket is mostly arranged inside a ground installation groove at the bottom of the landing sill, and the bracket is used to connect the wall and the component at the bottom of the landing sill, so as to complete the fixed installation of the landing sill.

[0003] Existing landing sill installation brackets are all plate-shaped brackets. One end of each bracket is connected to the landing sill, and the other end is installed on the wall. During actual use, especially in a factory during the process of transporting goods, larger goods are transported to another floor for processing by a forklift using an elevator. When passing through the elevator landing door opening, the bracket for fixing the elevator landing sill will bear a large pressure. However, the strength of the plate-shaped bracket itself is generally average, and there is a risk of fracture during long-term use, which may cause the landing sill to fall off, posing a certain safety risk. Content of the Utility Model

[0004] In order to reduce the safety risk, the present application provides a landing sill bracket.

[0005] The landing sill bracket provided by the present application adopts the following technical solution:

[0006] A landing sill bracket includes a first bottom plate and a second bottom plate connected to each other. The first bottom plate is provided with a first reinforcing block, the second bottom plate is provided with a second reinforcing block, the first bottom plate is provided with a first installation component for installing the first bottom plate, and the second bottom plate is provided with a second installation component for installing the second bottom plate.

[0007] By adopting the above technical solution, the bracket is located in the installation groove for installing the landing sill. The first bottom plate is installed at the bottom of the landing sill through the first installation component, and the second bottom plate is installed on the inner wall of the installation groove through the second installation component to complete the installation. The first bottom plate and the second bottom plate are connected and form a certain angle therebetween, so as to improve the overall strength of the bracket and reduce the possibility of the bracket breaking along the bend during use. At the same time, the first reinforcing block on the first bottom plate increases the strength of the first bottom plate along the length direction of the first reinforcing block, and the second reinforcing block on the second bottom plate increases the overall strength of the second bottom plate along the length direction of the second reinforcing block, thereby reducing the possibility of the bracket itself breaking when bearing a large pressure during long-term use, reducing the risk of the landing sill falling off, improving the safety performance, and reducing the safety risk.

[0008] Preferably, the first reinforcing block and the second reinforcing block are connected to each other.

[0009] By adopting the above technical solution, the first reinforcing block and the second reinforcing block are connected to each other, so that the two cooperate with the first bottom plate and the second bottom plate to form an L-shaped structure, thereby enhancing the strength of the first reinforcing block and the second reinforcing block, further enhancing the overall strength of the bracket, reducing the possibility of fracture during the use of the bracket, and reducing the safety risk.

On the other hand, the first auxiliary plate and the second auxiliary plate further enhance the overall strength of the first bottom plate and the second bottom plate, improve the stiffness in the length direction by setting the first auxiliary plate and the second auxiliary plate, and reduce the possibility of the first bottom plate or the second bottom plate being broken or fractured.

[0014] Preferably, the first auxiliary plate is connected to the second auxiliary plate.

[0015] By adopting the above technical solution, by connecting the first auxiliary plate and the second auxiliary plate, the strength of the two is enhanced, the possibility of the first auxiliary plate and the second auxiliary plate being bent is reduced, especially the possibility of bending and breaking at the connection between the first auxiliary plate and the first bottom plate and at the connection between the second auxiliary plate and the second bottom plate is reduced, and the overall strength is improved.

At the same time, the insertion block is inserted into the first connection slot and abuts against the inner wall of the first connection slot, further increasing the contact area to increase the friction force. At the same time, the installation bolt passes through the insertion hole of the insertion block, increasing the fixing area of the installation bolt and improving the stability of the installation bolt after installation and fixation, thereby improving the overall installation stability.

[0020] Preferably, the second bottom plate is provided with a second connection slot. The second installation component includes an expansion bolt and a second installation nut. The expansion bolt passes through the second connection slot. The expansion bolt is provided with an installation thread.
