[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] The structure of a locking mechanism for a flat-support plastic pressing block and a profile outer cover of an escape push bar provided by the present utility model is as Figure 1 and Figure 3 shown, including a bottom shell 1. A connecting rod 11 is placed at the central position inside the bottom shell 1. Protective covers 3 are covered at both ends of the bottom shell 1, and the top ends of the protective covers 3 are buckled with the ends of the profile outer cover 2. Bases 4 are installed at both ends inside the bottom shell 1, and the two bases 4 and the two ends of the connecting rod 11 are fixedly connected by bolts; a lock core rotating device 5 is rotatably connected to one end of the base 4, and when the plastic pressing block 7 is pressed down, the lock core rotating device 5 is rotated by a pressing device 6. A pressing device 6 is arranged on the surface of the base 4, and the top end of the pressing device 6 is hinged with a plastic pressing block 7. And a slidable profile outer cover 2 is arranged on the surface of the adjacent plastic pressing block 7. A locking assembly 8 is arranged at the top of the plastic pressing block 7, and the locking assembly 8 is used to lock and fix the profile outer cover 2. A support seat 9 is fixed to one side of the surface of the plastic pressing block 7 by bolts, and a roller 91 is rotatably connected to the surface of the support seat 9, and the roller 91 is in rolling cooperation with the protective cover 3.

[0020] During implementation, the two bases 4 are installed at both ends of the bottom shell 1 and the two bases 4 are fixed by the connecting rod 11. Subsequently, the profile outer cover 2 is inserted into the plastic pressing block 7 from one side. The two sides of the plastic pressing block 7 will enter the dovetail grooves inside the profile outer cover 2. Subsequently, the plastic pressing block 7 and the profile outer cover 2 are fastened by the locking assembly 8. After fastening, the protective covers 3 are covered at both ends of the bottom shell 1, and the top ends of the protective covers 3 are covered on the ends of the profile outer cover 2. When covering, the rolling action of the roller 91 on the surface of the support seat 9 increases the convenience during covering.

[0021] Further, as Figure 2 and Figure 4As shown in the figure, the locking assembly 8 includes a sliding groove 81, a sliding piece 82, a through hole 83 and a long screw 84. The sliding groove 81 is opened on one side of the plastic pressing block 7, and wedge-shaped surfaces 811 are arranged on both sides of the sliding groove 81. A sliding piece 82 is slidably arranged inside the sliding groove 81, and wedge-shaped platforms 821 are arranged on both sides of the sliding piece 82. The wedge-shaped platforms 821 and the wedge-shaped surfaces 811 cooperate with each other. A through hole 83 is arranged on one side of the surface of the plastic pressing block 7, and a long screw 84 is arranged inside the through hole 83. One end of the long screw 84 penetrates through the through hole 83 for bolt connection with the screw hole of the sliding piece 82.

[0022] During implementation, rotate the long screw 84 inside the through hole 83. The long screw 84 pulls the sliding piece 82 to move, so that the wedge-shaped platforms 821 and the wedge-shaped surfaces 811 cooperate with each other to push the two sides of the plastic pressing block 7 outwards. After being pushed out, the width of the plastic pressing block 7 will become larger and thus be fastened to the inside of the profile outer cover 2, realizing the fixing work of the profile outer cover 2 and the plastic pressing block 7, solving the problem that the existing flat-support plastic pressing block and the profile outer cover need to be fixed by bolts, improving the convenience during fixing, and reducing the labor intensity when fixing the flat-support plastic pressing block and the profile outer cover.

[0023] Working principle: During use, first install the two bases 4 at both ends of the bottom shell 1 and fix the two bases 4 through the connecting rod 11. Then insert the profile outer cover 2 into the plastic pressing block 7 from one side. The two sides of the plastic pressing block 7 will enter the dovetail grooves inside the profile outer cover 2. Then fasten the plastic pressing block 7 and the profile outer cover 2 through the locking assembly 8. After fastening, cover the protective covers 3 at both ends of the bottom shell 1. The top ends of the protective covers 3 cover the ends of the profile outer cover 2. When covering, the rolling of the rollers 91 on the surface of the support seat 9 increases the convenience during covering.

[0024] During the implementation of the locking assembly 8, by rotating the long screw 84 inside the through hole 83, the long screw 84 pulls the sliding piece 82 to move, so that the wedge-shaped platforms 821 and the wedge-shaped surfaces 811 cooperate with each other to push the two sides of the plastic pressing block 7 outwards. After being pushed out, the width of the plastic pressing block 7 will become larger and thus be fastened to the inside of the profile outer cover 2, realizing the fixing work of the profile outer cover 2 and the plastic pressing block 7, solving the problem that the existing flat-support plastic pressing block and the profile outer cover need to be fixed by bolts, improving the convenience during fixing, and reducing the labor intensity when fixing the flat-support plastic pressing block and the profile outer cover.
