Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and fig. 2 to fig. 7, an armrest guide rail assembly comprises a cover plate 1, wherein a plurality of guide rails 6 which are connected with each other are fixedly arranged on the cover plate 1, an armrest belt 7 is arranged on the guide rails 6, a spring bracket 5 is fixedly arranged in the guide rails 6, a guide rail connecting plate 3 is fixedly arranged at the bottom of the cover plate 1 through a first fastening piece 4, and a plurality of guide rails 6 are fixedly connected with the cover plate 1 through the first fastening piece 4 and the guide rail connecting plate 3.

The spring bracket 5 is matched with the shape of the guide rail 6, and the spring bracket 5 is fixedly connected with the guide rail 6 through the first fastening piece 4.

The spring bracket 5 is U-shaped, and the spring bracket 5 comprises side walls arranged on two sides, and the side walls of the spring bracket 5 are attached to the inner walls of the guide rails 6.

The rail connecting plate 3 is located between two adjacent rails 6.

In this embodiment, the first fastener 4 is a lock bolt.

Specifically, the cover plate is provided with a first hole 11, the bottom of the guide rail is provided with a second hole 12, and the locking bolt sequentially penetrates through the guide rail connecting plate 3, the first hole of the cover plate 1, the second hole of the guide rail 6 and the spring bracket 5 from bottom to top to fix the guide rail connecting plate.

The reinforcing ribs 2 are fixedly arranged at the bottom of the cover plate 1, a plurality of reinforcing ribs 2 are uniformly arranged at the bottom of the cover plate 1, connecting plates 8 are fixedly arranged among the reinforcing ribs 2, and the reinforcing ribs 2 are fixedly connected with the cover plate 1 through second fasteners.

The reinforcing rib 2 is in a rectangular frame shape with a slot, the second fastening piece 10 is a T-shaped bolt, and the reinforcing rib 2 is fixedly connected with the cover plate 1 through the T-shaped bolt.

Specifically, the side wall of the connecting plate 8 is provided with a clamping groove 9, and a T-shaped bolt is installed in the slot and the clamping groove 9 to fixedly connect the connecting plate 8 with the reinforcing rib 2.

As can be seen from fig. 1, in the escalator, the diagonal handrail device is connected to the respective support element section by means of standard elements, thereby completing the lap joint. The oblique handrails are not spliced, and the transverse splicing size of the oblique handrails is ensured by the longitudinal stress of the oblique handrails, the reinforcing ribs and the connecting plates, so that the oblique handrails are unreliable. Therefore, a connecting plate needs to be added to enhance the connection strength between two inclined handrails.

The added spring support 5 has an upper dimension slightly larger than the opening of the guide rail 6 and a lower dimension slightly smaller than the opening of the guide rail 6. When assembly is needed, the spring bracket 5 is pressed into the cavity of the guide rail 6 by using a tool, the good elasticity of the spring steel material ensures that the guide rail cannot deform, and the elastic deformation of the spring steel can continuously apply transverse force to the guide rail 5, so that the size of the port guide rail is not easy to change. After being pressed in, the two are connected and fastened by using a locking bolt. Each port of the diagonal arm is fitted into a spring bracket 5 so as to ensure that the dimensions of the splice of the rails 6 are controllable.

The guide rail connecting plate 3 is additionally arranged at the joint of each inclined handrail, and the two inclined handrails are locked at the port by the locking bolt, so that the joint problem can not occur between the two inclined handrails.

The first holes 10 and the second holes 11 of the cover plate and the guide rail are punched, counter bores are formed in the same positions of the cover plate and the guide rail 6 by using a positioning stamping die, blanking of the connecting plates of the spring bracket 5 and the guide rail 6 is completed by using a laser cutting process, one-to-one correspondence between the second holes of the handrail guide rail and the threaded holes of the connecting plates can be guaranteed, and large deviation cannot occur.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
