Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments so as to more clearly understand the technical idea claimed in the invention.
As fig. 2, fig. 3 shows the utility model discloses door and window pulley, include outer frame 1 and install in the loose pulley assembly 2 of outer frame 1, outer frame 1 has diapire 3 and sets up in the lateral wall 4 of diapire 3 both sides, lateral wall 4 has breach 5, install the solid piece 6 of card on the breach 5, the solid piece 6 of card includes mounting screw piece 7 and the solid foot piece 8 of card, mounting screw piece 7 spanes and locates between lateral wall 4, the solid foot piece 8 of card locates mounting screw 7 both ends and extends in the outer wall of lateral wall 4, mounting screw piece 7 corresponds 3 threaded connection of diapire has screw 9, the solid foot piece 8 of card is equipped with bump 10 towards the protrusion of lateral wall 4, lateral wall 4 corresponds bump 10 and is equipped with can be connected with bump 10 direction cooperation and can carry out the dysmorphism hole 12 of fixing a position to bump 10, screw 9 supports in that diapire 3 is rotatory to make bump 10 remove and be fixed a position in dysmorphism hole 12 along dysmorphism hole 12 in diapire 3.
Specifically, the special-shaped hole 12 includes a first positioning hole 13 which is positioned and matched with the bump 10 and is far away from the notch 5, a second positioning hole 14 which is positioned and matched with the bump 10 and is close to the notch 5, and a guide slot hole 15 which is arranged between the first positioning hole 13 and the second positioning hole 14, wherein the guide slot hole 15 is communicated with the first positioning hole 13 and the second positioning hole 14, and the guide slot hole 15 is narrower than the bump 10. The salient point 10 of the clamping sheet 6 is firstly positioned and connected with the first positioning hole 13 in a matching way, when the screw 9 is tightly propped against the bottom wall 3 to rotate so that the clamping sheet 6 moves, the salient point 10 enters the second positioning hole 14 from the first positioning hole 13 through the guide slotted hole 15 to be positioned and connected with the second positioning hole 14 in a matching way, and at the moment, the clamping sheet 6 moves to the clamping groove clamped and positioned on the pulley mounting section bar. For example, the shaped hole 12 may be an 8-shaped hole. It should be noted that the positioning fit between the protruding point 10 and the first positioning hole 13 and the second positioning hole 14 is not an interference fit, but the diameter of the protruding point 10 is slightly larger than the width of the guide slot hole 15 but smaller than the diameters of the first positioning hole 13 and the second positioning hole 14, so that when the hole walls of the guide slot hole 15 communicating the first positioning hole 13 and the second positioning hole 14 are smoothly transitionally connected with the hole walls of the first positioning hole 13 and the second positioning hole 14, the protruding point 10 can completely enter the second positioning hole 14 from the first positioning hole 13 through the guide slot hole 15 under the pulling force of screwing the screw 9.
When the door and window pulley is installed, the screw 9 is screwed to enable the convex point 10 to move along the special-shaped hole 12 in a guiding mode so that the clamping sheet 6 can move, as shown in fig. 4, after the clamping sheet 6 moves to the clamping groove clamped in the pulley installation section, the clamping sheet 6 can be positioned and fixed in the special-shaped hole 12 through the convex point 10 in a positioning mode, even if the screw 9 is loosened or completely falls off in the use process of the pulley, due to the positioning connection effect of the convex point 10 and the special-shaped hole 12, the clamping sheet 6 cannot be loosened, the clamping sheet 6 can still be firmly clamped in the clamping groove of the pulley installation section, and the pulley is installed more stably. Certainly, in an optimal case, the two end clamping and fixing leg pieces 8 of the screw mounting piece 7 are respectively provided with at least two convex points 10, and the two irregular holes 12 corresponding to the convex points 10 comprise at least two convex points, so that the positioning and connecting strength of the convex points 10 and the irregular holes 12 can be further ensured, and the clamping and fixing connection of the clamping and fixing piece 6 in the clamping groove of the pulley mounting section bar is firmer.
Various other changes and modifications may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such changes and modifications should fall within the scope of the present invention.
