AI Technical Summary
In existing technologies, it is difficult for screens to maintain flatness and tightness, resulting in localized loosening or bulging, which affects the screening effect.
The screen tensioning fixture uses a square frame, multiple clamps and a tensioning mechanism. The clamps are driven to move away from the center of the screen by manually rotating the manual screw, ensuring that the screen is fixed flat and taut on the frame. An aluminum alloy frame and anti-slip pads are used to increase friction and improve stability.
This method achieves a flat, tight, and fixed screen, reducing labor intensity, extending the screen's service life, and improving screening efficiency.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0023] Please refer to Figure 1 , Figure 2 and Figure 5 , the utility model is a kind of screen tension clamp tool, including the square frame body 10 for placing screen 9 in the inside and the multiple clamps 20 for clamping screen on frame body 10. In the embodiment, frame body 10 is aluminum alloy frame body. Aluminum alloy has the advantages of light weight, high strength and good corrosion resistance. Adopting aluminum alloy frame body not only reduces the weight of the entire tool, facilitates operation and installation, but also can ensure that it is not easy to rust and corrode in long-term use, thereby prolonging the service life of tool.
[0024] In the embodiment, multiple supporting legs 13 for stabilizing are arranged on the lower surface of frame body 10.
[0025] As Figure 1 shown, in the embodiment, the four top corners of frame body 10 are provided with abutting end faces 101. The number of clamps 20 is four, and the four clamps 20 are distributed at the four corner portions of frame body 10.
[0026] Combined Figure 3 and Figure 4As shown, the clamp 20 comprises an upper clamp body 21, a lower clamp body 22, a handle 23, and a connecting pressure rod 26. The upper clamp body 21 and the lower clamp body 22 each comprise a Y-shaped bracket 28 extending to the inside of the frame 10 and a strip-shaped clamp head 29 connected to the front end of the bracket 28. The clamp head 29 of the upper clamp body 21 and the clamp head 29 of the lower clamp body 22 are opposite to each other. The bracket 28 comprises a horizontal rod 281 and a bifurcated rod 282 connected to the front end of the horizontal rod 281. The bracket 28 of the upper clamp body 21 has a vertical hinge 211 at the rear end. The bracket 28 of the lower clamp body 22 has a vertical connecting part 222 and a lower horizontal hinge 221 connected to the upper end of the vertical connecting part 222. The handle 23 is divided into a horizontal part 231 and an upper horizontal hinge 232 connected to the front end of the horizontal part 231. The vertical hinge 211, the lower horizontal hinge 221, the connecting pressure rod 26, and the upper horizontal hinge 232 are sequentially and hinge-connected to form a quadrilateral mechanism.
[0027] The hinge connection mode of the vertical hinge, the lower horizontal hinge, the connecting pressure rod, and the upper horizontal hinge is as follows: the vertical hinge 211 has a vertical slot 24, the upper part of the slot 24 has a first hinge point A, and the lower part has a second hinge point B. The lower horizontal hinge 221 has a third hinge point C and a fourth hinge point D at the same height at the two ends. The upper horizontal hinge 232 has a fifth hinge point E at the free end, and a sixth hinge point F at the corner between the upper horizontal hinge 232 and the horizontal part 231. During assembly, the lower horizontal hinge 221 of the lower clamp body 22 is inserted into the lower part of the slot 24 so that the fourth hinge point D coincides with the second hinge point B, and then the lower end of the reinforcing plate 25 is hinge-connected together. The upper horizontal hinge 232 of the handle 23 is inserted into the upper part of the slot 24 so that the fifth hinge point E coincides with the first hinge point A, and then the upper end of the reinforcing plate 25 is hinge-connected together. The sixth hinge point F at the corner of the handle 23 and the third hinge point C on the lower horizontal hinge 221 of the lower clamp body 22 are hinge-connected together through the connecting pressure rod. In this way, when the handle 23 is pressed downward, the clamping force increases due to the increase in the distance between the first hinge point A and the third hinge point C. The clamp head 29 of the upper clamp body 21 swings downward around the fourth hinge point D, and cooperates with the clamp head 29 of the lower clamp body 22 to clamp the screen.
[0028] In the embodiment, the clamp head 29 of the upper clamp body 21 and the clamp head 29 of the lower clamp body 22 are each connected with an anti-skid pad 27. The use of the anti-skid pad can increase the friction between the clamp and the screen, thereby improving the stability of clamping. At the same time, the anti-skid pad can also protect the surface of the screen and reduce the damage of the clamp to the screen, thereby prolonging the service life of the screen. The anti-skid pad 27 can be a rubber anti-skid pad.
[0029] As Figure 3 and Figure 4The tensioning mechanism 30 is arranged outside each corner of the frame 10. The tensioning mechanism 30 comprises a threaded hole 223 arranged on the clamp 20 and facing the supporting end face 101, a hand screw 31 arranged in the threaded hole 223 and having an end capable of abutting against the supporting end face 101, and a support structure 35 fixed on the frame 10 and used for supporting and guiding the horizontal movement of the clamp 20. In this way, after the handle is pressed downward to clamp the screen 9, the clamp 20 clamping the screen 9 is driven to move away from the center of the screen 9 by manually rotating the hand screw 31, so as to tighten the screen 9. At the same time, the tightened screen 9 generates a pulling force on the clamp 20 in the direction of the center of the screen 9, so that the clamp 20 can be kept in the clamping state. The hand screw 31 has a knob 311 at the rear end. The threaded hole 223 is arranged on the vertical connecting portion 222.
[0030] In the embodiment, the support structure 35 comprises two support blocks 32 welded on the lower surfaces of the corners of the frame 10 and a horizontal sliding groove 225 arranged on the bracket 28 of the lower clamp body 22. The bracket 28 of the lower clamp body 22 is arranged in the clamping groove 33 between the two support blocks 32. The horizontal sliding groove 225 is provided with a pin 34, and the two ends of the pin 34 are fixedly connected to the two support blocks 32, respectively.
[0031] The above is the screen tensioning clamp tool of the utility model. In use, first, the handles 23 of the clamps 20 are pushed upward to open all the clamps. Then, the screen 9 is placed in the frame 10. Then, all the handles are pressed downward to close the clamps and clamp the four top corners of the screen. Then, the hand screw 31 is rotated to drive the clamps 20 to move away from the center of the screen, and the movement of the clamps promotes the screen 9 to be fixed on the frame in a flat and tight manner.
[0032] The above describes one embodiment of the utility model in detail, but the content described is only the preferred embodiment of the utility model and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement within the scope of the utility model application should still belong to the patent coverage range of the utility model.
