[0002] The linear screen and the square swing screen are the two largest types of fine powder screening equipment. They have the advantage of large screening output, but the replacement of the screen is time-consuming and labor-intensive. At present, the linear screen frame is mainly stacked layer by layer and pressed in the box with a screw. The main pressing direction is up and down, and the left and right rely on friction and are not convenient to disassemble. The upper cover needs to be removed. The square swing screen currently has a screw-tightening structure on the outside. It only has left and right pressing force and no up and down pressing force, which causes abnormal noise and loosening of the frame after the equipment has been used for a period of time.

[0003] At present, the existing grid has only unidirectional pressing force. The linear screen is generally pressed up and down, and the square swing screen is pressed left and right. It cannot guarantee that it will not loosen during long-term operation and cannot be disassembled quickly. Therefore, it is necessary to propose a new type of pull-out grid pressing device to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a new pull-out mesh frame clamping device, which aims to improve the problem that the existing mesh frame has only one-way clamping force, the linear screen is generally clamped up and down, and the square swing screen is clamped left and right, which cannot ensure long-term operation without loosening and cannot be disassembled quickly.

The first locking portion 230 is installed on the supporting frame body 100, and the first locking portion 230 is in contact with the wedge plate 221.

[0028] The first locking portion 230 includes a first internally threaded guide sleeve 231, which is evenly fixed on both sides of the support frame body 100. The internal thread of the first internally threaded guide sleeve 231 is connected with a tapered bolt 232, and the end of the tapered bolt 232 is tightly attached to the wedge plate 221. A rotating block 233 is fixed on the tapered bolt 232; the rotating block 233 is a regular hexagon, and one end of the tapered bolt 232 is tapered and matches the inclination of the wedge plate 221. A through hole matching the tapered bolt 232 is opened on the connecting frame 220; here, the tapered bolts 232 on both sides are used to move back and forth in the first internally threaded guide sleeve 231, and their ends are squeezed on the wedge plate 221 on the top surface of the connecting frame 220, so that the drawer grid 210 can be conveniently fastened, and it can be conveniently pulled out and disassembled after loosening, and the disassembly and assembly is more convenient.

[0029] See also Figure 1-Figure 8 The screen assembly 300 includes a screen 310, a second locking portion 320 and a hook plate assembly 330. Connecting angle plates 311 are fixed on both sides of the screen 310. The screen 310 is placed on the connecting frame 220. The second locking portion 320 is installed on the waist-shaped hole 101 and clamped on the connecting angle plate 311. The hook plate assembly 330 is installed at both ends of the support frame 100.

[0030] The second locking part 320 includes a clamping frame 321 and a fastening bolt 322. The fastening bolt 322 passes through the clamping frame 321 and the waist-shaped hole 101, and the end of the fastening bolt 322 is threadedly connected to the fastening nut 323; two fastening nuts 323 are provided, and a circular hole matching the fastening bolt 322 is opened inside the clamping frame 321, and the two ends of the clamping frame 321 are respectively clamped on the connecting angle plate 311 and the supporting angle plate 120; here, the fastening bolt 322 can drive the clamping frame 321 to slide up and down in the waist-shaped hole 101, and at the same time, the fastening bolt 322 and the clamping frame 321 can be positioned and fixed by utilizing the extrusion of the fastening nut 323 and the surface of the support frame body 100.

[0031] The hook plate assembly 330 includes a second internal thread guide sleeve 331, and the second internal thread guide sleeve 331 is symmetrically fixed to the two ends of the support frame 100. The internal thread of the second internal thread guide sleeve 331 is connected with a rotating screw 332, and one end of the rotating screw 332 is fixed with a hook plate 333. The hook plate 333 is located inside the clamping frame 321. Here, the hook plate assembly 330 is distributed at both ends and both sides of the support frame 100. After loosening the fastening nut 323, by rotating the rotating screw 332 makes the hook plate 333 in a vertical state, which can prop up the clamping frame 321 downward, and at the same time, the lower end of the clamping frame 321 is away from the connecting angle plate 311, which makes it convenient to pull out the screen 310.

[0032] Specifically, the working principle of the new pull-out grid clamping device is as follows: when in use, the connecting frames 220 on both sides of the drawer grid 210 are placed on the supporting angle plates 120 and pushed into the interior of the supporting frame body 100, and then the tapered bolts 232 on both sides of the supporting frame body 100 are rotated to make them move toward one side of the connecting frame 220 inside the first internal threaded guide sleeve 231, and then pass through the through holes on the connecting frame 220 and squeeze on the inclined surface of the wedge plate 221, so that the drawer grid 210 can be tightened from both sides, and at the same time, the ends of the tapered bolts 232 are away from the inclined surface of the wedge plate 221 to loosen the drawer grid 210 for easy pulling and removal; at this time, the connecting angle plates 311 on both sides of the screen 310 are placed on the top surface of the connecting frame 220, so that the rotating screw 332 is rotated to rotate the hook plate 333 When the cam 310 is in a state of being horizontal, the clamping frame 321 and the second locking portion 320 move downward, and the end of the clamping frame 321 is clamped on the connecting angle plate 311. At this time, the clamping frame 321 can be fixed by rotating the fastening nut 323 and squeezing it against the surface of the support frame body 100, and the connecting angle plate 311 and the screen 310 can be positioned at the same time. Otherwise, the fastening nut 323 is loosened and the rotating screw 332 is rotated to make the hook plate 333 in a vertical state. In this way, the clamping frame 321 will be lifted up by the hook plate 333 and away from the connecting angle plate 311, which can facilitate the compression and fixation of the screen 310 and facilitate disassembly and assembly. In this way, it can be compressed and fixed from multiple directions such as up, down, left and right, which is conducive to keeping it from loosening during long-term operation. At the same time, such compression and fixation also facilitates quick disassembly and assembly, which is more convenient to use.
