Description

Technical Field

[0001] The utility model relates to the technical field of elevator toe guard board components, in particular to a telescopic elevator toe guard board component. Background Art

[0002] In the field of elevators, in order to ensure safety in use, the industry stipulates that the car must be equipped with a toe guard to prevent the situation in which, during the rescue process, if the elevator does not stop at the level floor, passengers slip and fall into the elevator shaft when escaping from the elevator. Publication No. CN205772690U discloses an elevator toe guard, including a toe guard body, brackets arranged on both sides of the toe guard body, and a mounting portion located at the upper end of the toe guard body for fixing the toe guard; and also includes a collection trough arranged at the lower end of the toe guard body for accommodating debris dropped from the elevator car. The elevator toe guard provided by the utility model has a toe guard body, a bracket and a mounting portion, and the toe guard is fixedly installed at the elevator sill through the mounting portion, and a collection trough is also arranged at the lower end of the toe guard body. When in use, dust and other garbage in the gaps of the elevator will fall down and fall into the collection trough. When maintaining the elevator, it is only necessary to clean the garbage in the collection trough, and there is no need to clean the pit as a whole, thereby avoiding the situation where garbage falls directly into the elevator pit, thereby saving cleaning time and improving cleaning efficiency, while also reducing the labor burden of maintenance personnel. However, the toeboard is not provided with a transverse telescopic structure, which makes the toeboard unable to be used in elevators of different sizes, thereby reducing the use effect of the toeboard. The toeboard still has shortcomings and needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: a telescopic elevator toe guard assembly, comprising a plate sleeve and a toe guard body, a connecting plate is fixedly installed on one side of the toe guard body, a fixing plate is symmetrically fixedly installed on one side of the plate sleeve, a fixing column is symmetrically fixedly installed on the inner side of the fixing plate, a screw rod is installed inside the fixing plate, and a knob is fixedly installed on one end of the screw rod.

[0005] Preferably, the outer wall of the knob is evenly provided with semicircular grooves, thereby improving the anti-slip effect when the knob is turned by the semicircular grooves.

[0006] Preferably, a long board is fixedly mounted on the top of the plate sleeve, and mounting holes are evenly opened on one side of the long board. Here, the mounting holes facilitate fixing the long board to the elevator.

[0007] Preferably, the connecting plate is connected to the fixing column by sliding, and the connecting plate is connected to the screw rod by threading. Here, the limiting effect of the connecting plate during adjustment is improved by the sliding connection, and the adjustment effect of the connecting plate is improved by the threaded connection.

[0008] Preferably, the screw rod and the fixing plate are connected via a bearing. Here, the connection via the bearing improves the rotation effect of the screw rod.

[0009] Preferably, one side of the plate sleeve is evenly fixed with reinforcing transverse ribs, and the side of the plate sleeve close to the reinforcing transverse ribs is evenly fixed with reinforcing vertical ribs. Here, the overall strength of the plate sleeve is improved by the coordinated use of the reinforcing transverse ribs and the reinforcing vertical ribs, effectively preventing the plate sleeve from being easily bent during use.

[0010] Preferably, the reinforcing transverse ribs and the reinforcing vertical ribs are fixedly connected. Here, the use effect of the reinforcing transverse ribs and the reinforcing vertical ribs is improved by the fixed connection.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, a plate sleeve, a connecting plate, a fixing plate, a fixing column, a screw rod and a knob are provided. By turning the knob, the screw rod is driven to rotate inside the fixing plate. During the rotation of the screw rod, the connecting plate is driven to slide on the outer wall of the fixing column. During the sliding process, the connecting plate is driven to slide the toe guard body inside the plate sleeve. After sliding a suitable distance, the knob is stopped. This structure can quickly extend and retract the toe guard body, so that the toe guard body can be used for elevators of different sizes, effectively avoiding the problem that the toe guard body cannot be extended and retracted, resulting in only one size of elevator being used.

[0013] 2. In the present invention, by providing reinforcing transverse ribs and reinforcing vertical ribs, the overall strength of the plate sleeve is improved through the coordinated use of the reinforcing transverse ribs and the reinforcing vertical ribs, and the plate sleeve is effectively prevented from being easily bent during use.
