[0002] Square sieves play a vital role in industries such as mining, construction, chemicals, and food processing. In the mining industry, they are used to screen ores of different particle sizes for ore grading; in the construction industry, they are used to screen building materials such as sand and gravel; in the chemical industry, they are used to separate chemical raw materials of different particle sizes; and in the food processing industry, they are used for fine screening of food ingredients to ensure food quality. Square sieves have a wide range of applications.
[0003] Existing square screen hook plates tighten by using tensioning plates to fasten the tensioning plates on both sides of the screen, and then using horizontal bolts to pull the tensioning plates together. This method does not allow for adjustment of the screen tension. During operation, the screen easily wobbles due to the weight of the material and the inertial force generated by high frequency, resulting in screen loosening and reduced production efficiency. Therefore, a square screen hook plate with adjustable tension is proposed to solve these problems. Utility Model Content

[0006] A square screen hook plate for easy tension adjustment includes a screen frame and a hook plate. The hook plate is slidably connected inside the screen frame, and a bolt is fixedly connected inside the hook plate. A nut is threaded onto the outside of the bolt. A sliding groove is opened inside the screen frame, and the bolt is slidably connected inside the sliding groove. A tensioning structure is fixedly connected inside the screen frame for adjusting the screen mesh.
[0007] As a further description of the above technical solution:

[0016] A screen hook plate is placed inside the hook plate, and the right side of the adjusting bolt fixes the screen hook plate.
[0017] As a further description of the above technical solution:
[0018] The hook plate is externally fixed with shock-absorbing foam to reduce vibration;
[0019] As a further description of the above technical solution:
[0020] A support plate is fixedly connected to the outside of the screen frame. The top of the support plate is in contact with the bottom of the screen hook plate to support the screen hook plate and make it fit together.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the hook plate is pushed outward by rotating the nut, the screen is placed on the support and folded, and the nut is tightened to fix the hook plate.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a square screen hook plate with adjustable tension, comprising a screen frame 1 and a hook plate 2. The hook plate 2 is slidably connected inside the screen frame 1, and a bolt 8 is fixedly connected inside the hook plate 2. A nut 12 is threaded onto the outside of the bolt 8. Rotating the nut 12 pushes the hook plate 2 outward. A groove 9 is provided inside the screen frame 1, and the bolt 8 is slidably connected inside the groove 9. The bolt 8 slides in the groove 9, causing the hook plate 2 to slide up and down for easy placement of the screen. A tensioning structure is fixedly connected inside the screen frame 1 for adjusting the screen. The bolt 8 is threaded onto the inside of the screen frame 1 for pulling the hook plate 2 to the screen frame 1 for fixation. A buffer pad 11 is fixedly connected to the outside of the screen frame 1. The buffer pad 11 is provided between the screen frame 1 and the nut 12 to reduce wear between the bolt 8 and the hook plate 2. The bolt 8 is slidably connected inside the buffer pad 11 to reduce noise during operation. The hook plate 2 is externally fixed with a shock-absorbing sponge 13 to reduce vibration. The shock-absorbing sponge 13 has a certain elasticity, which can keep the screen frame 1 and the hook plate 2 taut and improve stability.
[0031] Reference Figure 1 and Figure 3The tensioning structure includes a connecting rod 10, which is externally fixed to the inside of the screen frame 1. An adjusting bolt 7 is threaded inside the connecting rod 10. Rotating the adjusting bolt 7 compresses the spring 6, causing the adjusting bolt 7 to slowly move forward and contact the screen hook plate 4. The spring 6 is sleeved on the outside of the adjusting bolt 7. When in contact with the screen hook plate 4, the spring 6 is in an unfolded state. Rotating the adjusting bolt 7 moves it outward, and the spring 6 is in a compressed state. A limiting groove 3 is fixedly connected to the end of the bolt 8 away from the nut 12, and the limiting groove 3 contacts the hook plate 2. The screen hook plate 4 is placed inside the hook plate 2, and the right side of the adjusting bolt 7 fixes the screen hook plate 4. A support plate 5 is fixedly connected to the outside of the screen frame 1. The top of the support plate 5 fits against the bottom of the screen hook plate 4, supporting the screen hook plate 4 in contact with the hook plate 2. The tension of the screen is adjusted by rotating the adjusting bolt 7, making the entire tensioning process simple and effective, and the structure stable and not easily damaged.
[0032] Working principle: By rotating the nut 12, the hook plate 2 is pushed outward, and the bolt 8 slides in the groove 9, causing the 2 to slide up and down for easy placement of the screen. The screen is placed on top of the support plate 5 and folded inward towards the hook plate 2. Tightening the nut 12 causes the hook plate 2 to be fixed towards the screen frame 1. As the hook plate 2 adheres to the screen frame 1, the shock-absorbing sponge 13 is compressed. The shock-absorbing sponge 13 has a certain elasticity, which keeps the screen frame 1 and the hook plate 2 taut, improving stability. A buffer pad 11 is provided between the screen frame 1 and the nut 12 to reduce wear between the bolt 8 and the hook plate 2.
[0033] By rotating the adjusting bolt 7, the spring 6 is compressed, and the adjusting bolt 7 slowly moves forward to contact the screen hook plate 4, fixing the screen hook plate 4 on the hook plate 2. The tension of the screen is adjusted by rotating the adjusting bolt 7, making the entire tensioning process of the screen simple and effective, and the structure stable and not easily damaged.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
