They are mainly used to ensure that the elevator car and counterweight device move up and down along them. They are also used for the inclined or horizontal movement of escalator and moving walkway steps. Elevator guide rails are composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. From the cross-sectional shape, they can be divided into three types: T-shaped, L-shaped and hollow: Elevator guide rails require connectors for support during installation;

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example: Figure 1-3As shown, the utility model provides a connecting piece for an elevator guide rail, comprising a base plate 1, an internal movable card of the base plate 1 is provided with symmetrically distributed extension plates 11, a stabilizing plate 12 is fixedly installed on one side of the extension plate 11, and a symmetrically distributed first fixing hole 13 is opened on the top of the stabilizing plate 12, a connecting plate 14 is fixedly installed on the side of the top of the extension plate 11 away from the stabilizing plate 12, the connecting plate 14 is in a trapezoidal state, and a symmetrically distributed second fixing hole 15 is opened on the top of the connecting plate 14, a side of the extension plate 11 close to the connecting plate 14 is provided with evenly distributed third fixing holes 16, and a side of the base plate 1 close to the third fixing hole 16 is provided with evenly distributed fourth fixing holes 17, and the third fixing hole 16 and the fourth fixing hole 17 are used in conjunction with each other.

[0017] Two groups of symmetrically distributed limit grooves 2 are provided at the top of the base plate 1, and symmetrically distributed limit blocks 21 are fixedly installed at the top of the extension plate 11. The limit blocks 21 penetrate the limit grooves 2, and a stabilizing groove 22 is provided on the top of the limit blocks 21. A symmetrically distributed movable plate 23 is slidably provided at the top of the base plate 1, and two fixed plates 24 are fixedly installed at the top of the movable plate 23. A uniformly distributed clamping block 25 is fixedly installed on one side of the fixed plate 24 close to the limit block 21, and the clamping block 25 is used in conjunction with the stabilizing groove 22.

[0018] A card plate 3 is fixedly installed at the bottom end of the movable plate 23, and a card slot 31 is opened at the top of the bottom plate 1. The card plate 3 is movably clamped in the card slot 31. By setting the card plate 3 and the card slot 31, the stability of the movable plate 23 during movement is improved, thereby better fixing the stable groove 22; the length of the card slot 31 is slightly longer than that of the card plate 3, so that the movable plate 23 can move normally.

[0019] A mounting plate 4 is fixedly installed on one side of the movable plate 23 close to the fixed plate 24. Evenly distributed stabilizing holes 41 are provided on the top of the mounting plate 4 and the bottom plate 1. By setting the mounting plate 4 and the stabilizing holes 41, the mounting plate 4 can be fixed by fixing screws to prevent the movable plate 23 from moving and improve its stability.

[0020] A symmetrically distributed reinforcing plate 5 is fixedly installed on one side of the extension plate 11 close to the stabilizing plate 12 . The reinforcing plate 5 and the stabilizing plate 12 are fixedly connected. By providing the reinforcing plate 5 , the stability of the connection between the extension plate 11 and the stabilizing plate 12 is improved.

[0021] A transverse plate 6 is fixedly installed on one side of the connecting plate 14, and a symmetrically distributed bracket 61 is fixedly installed on one side of the top of the bottom plate 1 close to the connecting plate 14. The transverse plate 6 is movably clamped in the bracket 61. By setting the transverse plate 6 and the bracket 61, the pressure on the connecting plate 14 can be reduced and its stability can be improved.

[0022] The number of the third fixing holes 16 is four, and the number of the fourth fixing holes 17 is eight, so that the staff can install different numbers of fixing screws according to the adjusted distance of the extension plate 11.

[0023] Working principle: In actual use, the extension plate 11 is pulled out of the base plate 1 for a certain distance and adjusted according to the width of the guide rail. When it is adjusted to a suitable distance, the fixing screws are passed through the third fixing hole 16 and the fourth fixing hole 17 to fix the extension plate 11. Then, the stabilizing plate 12 is attached to the inner wall of the elevator shaft and fixed by expansion screws. When the extension plate 11 moves, the movable plate 23 is pulled to drive the fixed plate 24 and the block 25 to move, so that the block 25 is disengaged from the stabilizing groove 22. When the extension plate 11 is completely moved, the movable plate 23 is pushed to make the block 25 re-enter the stabilizing groove 22.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
