[0026] according to Figure 1-7 As shown:

[0027] A tension beam for a screen window, comprising:

[0028] The beam 1 drives the screen to move in the window frame 100;

[0029] The plug 2 is installed on both sides of the beam body 1. The plug 2 is provided with a matching portion 21 and an extrusion piece 22. The matching portion 21 is located on the end surface of the plug 2, and the extrusion piece 22 is located on one side of the matching portion 21. There is a hollow layer 200 between the extrusion piece 22 and the matching portion 21.

[0030] The window frame 100 is clamped on the hollow layer 200 and is clamped and pressed by the matching portion 21 and the extrusion member 22. The extrusion member 22 applies force to the window frame 100 through the elastic member. In this structure, the elastic member is not shown in the figure.

[0031] Specifically, the plug 2 is adapted to the beam body 1, and the plug 2 is provided with a mounting portion 23 on the side opposite to the matching portion 21. The mounting portion 23 is adapted to the hollow groove 11 of the beam body 1. At the same time, there is a positioning hole 24 in the middle of the mounting portion 23. The positioning hole 24 extends from the outside of the matching portion 21 to the inside of the mounting portion 23. The positioning hole 24 is penetrated by a bolt and connected to the beam body 1. Finally, the plug 2 also has a built-in groove 25 to cooperate with the beam body 1 to install the mesh. Specifically, after the plug 2 is adapted to the beam body 1, at this time, an upward surface of the plug 2 needs to be adapted to the beam body 1, and there is an opening 600 on the structural surface, which extends downward in a groove shape to form a built-in groove 25. The orifice of the cross section of the positioning hole 24 is connected to the built-in groove 25.

[0032] Specifically, the matching part 21 is a movable wheel 211 fixed on the end face of the plug 2 through a shaft 212. The movable wheel 211 is symmetrically designed on the end face. In order to ensure the stability of the matching part 21 window frame 100 and the structure, two sets of movable wheels 211 are evenly arranged on the end face of the plug 2.

[0033] Specifically, the shaft 212 is located in the concave groove 300, so that the movable wheel 211 is limited in the concave groove 300, ensuring the smooth rotation of the movable wheel 211. It should be noted that the shaft 212 in this structure is fixed integrally with the plug 2. At the same time, it can also be fixed by an external shaft 212 that passes through the plug 2, and this connection method can also be realized.

[0034] Specifically, the end face of the plug 2 is provided with an outward expansion end 26 adapted to the extrusion piece 22, and the extrusion piece 22 is located in the slide groove 27 of the outward expansion end 26. The outward expansion end 26 limits the window frame 100 and cooperates with the extrusion piece 22 to clamp it. The extrusion piece 22 includes a pulley 221, a rod body 222 for mounting the pulley 221, and a force-bearing portion 223 located on one side of the rod body 222. The rod body 222 is mounted on the pulley 221 through the positioning portion 224, and is clamped by the slide. The wheel 221 presses against the window frame 100, and the side of the rod body 222 away from the pulley 221 is the force-bearing part 223, and the force-bearing part 223 has a groove 225 adapted to the elastic member. When the pulley 221 is subjected to the force of the window frame 100, the force-bearing part 223 is pulled by the rod body 222 to squeeze the elastic member to form a stable clamping force. At the same time, a protrusion 226 is also provided under the rod body 222, and the rod body 222 is adapted to be connected to the slide groove 27 through the protrusion 226.

[0035] In this structure, the positioning is to clamp the pulley 221, which is an existing conventional fixing method.

[0036] The cam 28 is pressed against the support 223 by the spring 226 and the spring 226 is pressed against the support 223 by the spring 226.

[0037] The plug 2 is installed on both sides of the beam body 1. The matching part 21 and the outward expansion end 26 are first used to limit and fix the window frame 100, and then the movable wheel 211 is used to balance the traction. In combination with the extrusion part 22 with an elastic part, when the beam body 1 is pulled on the window frame 100, the problem of the pull beam tilting or loosening when the window frame 100 slides is solved, thereby ensuring the effect of balanced pulling.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
