[0001] The utility model relates to the technical field of elevator guide rail brackets, in particular to a guide rail bracket for installing elevator guide rails. Background Art
[0002] Elevator guide rail brackets are components used to support and fix guide rails, usually installed on the shaft wall or beam. The function of the guide rail bracket is to fix the spatial position of the guide rail and withstand various actions from the guide rail.
[0003] The fixing method of the elevator guide rail bracket is generally pre-embedded steel plate, direct burial, pre-embedded anchor bolts, and then the elevator guide rail bracket is fixed in the elevator shaft with the anchor bolts, and then the elevator guide rail is installed on the surface of the elevator guide rail bracket with bolts. However, the elevator guide rail bracket in the prior art does not have an anti-loosening mechanism, that is, after the elevator guide rail and the elevator guide rail bracket are fixed together with bolts, it is possible that the bolts are reversed and loosened when subjected to vibration, which is prone to safety hazards. Therefore, an improved guide rail bracket for installing elevator guide rails is needed to address this problem. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide rail bracket for installing an elevator guide rail, comprising a bracket, mounting plates are fixedly arranged on both sides of the bracket surface, a guide rail is arranged on one side of the bracket surface, a plurality of locking screws are fixedly arranged on the outer surface of the guide rail, a mounting hole is opened on the outer surface of the bracket, a fixing mechanism is arranged between the locking screw and the mounting hole, and the fixing mechanism comprises a fixing ring, a ratchet, a locking nut, a fixing disk, a notch, and a pawl, a fixing ring is fixedly arranged on the surface of the bracket outside the mounting hole, a plurality of ratchets are evenly opened on the inner side wall of the fixing ring, a locking nut is arranged on one end of the locking screw passing through the mounting hole through a threaded movably screwed, a fixing disk is fixedly arranged on the outer surface of the locking nut, a notch is opened on the outer surface of the fixing disk, and a ratchet is movably arranged on one side inside the notch through a rotating shaft.
[0006] Preferably, a spring is fixedly arranged at the lower end of the pawl inside the notch, and the pawl can be automatically pushed to reset by the spring; Figure 3 Status shown.
[0007] Preferably, a limit plate is fixedly provided at the upper end of the pawl inside the notch, and the rotation angle of the pawl can be limited by the limit plate.
[0008] Preferably, a plurality of fixing holes are evenly formed on the outer surface of the mounting plate, and the mounting plate and the bracket can be conveniently fixed inside the elevator shaft through the fixing holes in cooperation with pre-buried anchor bolts.
[0009] Preferably, a stabilizing block is fixedly provided between the bracket and the mounting plate, and the stability between the bracket and the mounting plate can be improved by the stabilizing block.
[0010] Preferably, a clamping block is fixedly provided at the lower end of the guide rail, and a clamping groove is provided on the outer surface of the upper end of the guide rail. The guide rails can be conveniently spliced together through the clamping block and the clamping groove to ensure the stability between the guide rails.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. When the locking nut of the utility model is tightened, the pawl will rotate relative to the fixing ring in the counterclockwise direction; at this time, the pawl and the ratchet will not engage with each other; thus, the tightening work of the locking nut will not be affected. After the locking nut is fully tightened, when you want to loosen it, the pawl and the ratchet will rotate relative to each other clockwise, and at this time, the pawl and the ratchet will engage with each other, thereby preventing the locking nut from loosening. In this way, after the locking nut is tightened and fixed, this structure can effectively prevent the locking nut from being reversed and loosened due to any non-human reasons; thereby, the fixing effect of the device can be improved.
[0013] The entire clamping process of the utility model is more convenient. Compared with the prior art, there is only one more step that requires human intervention. The worker needs to press the clamping claw by hand to shrink the clamping claw inside the notch. Only this one more step is required. All subsequent installation steps are consistent with the tightening of traditional locking screws. The screws can be tightened with a socket wrench, which makes it easy to promote and use.

[0023] A limit plate 13 is fixedly arranged at the upper end of the pawl 10 inside the notch 9, and the rotation angle of the pawl 10 can be limited by the limit plate 13;
[0024] The outer surface of the mounting plate 2 is evenly provided with a plurality of fixing holes 14, and the mounting plate 2 and the bracket 1 can be conveniently fixed inside the elevator shaft through the fixing holes 14 and the embedded anchor bolts;
[0025] A stabilizing block 15 is fixedly disposed between the bracket 1 and the mounting plate 2, and the stabilizing block 15 can improve the stability between the bracket 1 and the mounting plate 2;
[0026] A clamping block 16 is fixedly provided at the lower end of the guide rail 3 , and a clamping groove 17 is provided on the outer surface of the upper end of the guide rail 3 . The clamping block 16 and the clamping groove 17 can be used to conveniently splice the guide rails 3 together to ensure the stability between the guide rails 3 .
[0027] Working principle: When using this device, the mounting plate 2 and the bracket 1 can be conveniently fixed inside the elevator shaft through the fixing hole 14 with the pre-buried anchor bolts, and then the guide rail 3 and the bracket 1 can be installed. During installation, the locking screw 4 fixedly welded to the guide rail 3 is passed through the mounting hole 5 and the fixing ring 6; Figure 2 , Figure 3 The state shown is then connected to the locking screw 4 by threading, and then the socket wrench is set on the surface of the locking nut 7 to slowly tighten the locking nut 7. At this time, as the locking nut 7 is tightened, when the pawl 10 is about to enter the interior of the fixing ring 6, human intervention is required. The worker needs to press the clamping claw by hand to shrink the clamping claw inside the notch 9, and then continue to rotate the locking nut 7; eventually, the fixing plate 8 and the pawl 10 will enter the interior of the fixing ring 6, and then continue to rotate the locking nut 7.

After the locking nut 7 is fully tightened, when it is desired to loosen it, the pawl 10 and the ratchet teeth 11 rotate relative to each other in the clockwise direction, at which time the pawl 10 and the ratchet teeth 11 engage with each other, thereby preventing the locking nut 7 from loosening. In this way, after the locking nut 7 is tightened and fixed, the present structure can effectively prevent the locking nut 7 from being reversed and loosened due to any non-human reasons; thereby, the fixing effect of the present device can be improved.

The worker needs to press the clamping jaw by hand to shrink the clamping jaw inside the notch 9. Only this one more step is required. All subsequent installation steps are consistent with tightening the traditional locking screw 4; it can be tightened with a socket wrench, which can be easily promoted and used.
