[0022] 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.

[0023] Please see Figures 1 to 6 This utility model provides a pressing device for a square air purification box for nuclear applications; it includes a box body 1 and a box door 2, with the box door 2 fixedly connected to the front of the box body 1.

[0024] The housing 1 includes an internal sealing plate 3, a purification box 4 located below the sealing plate 3, and a pressing frame 5 located at the bottom of the purification box 4 for pressing it. The bottom of the pressing frame 5 is provided with a triangular steel 6 for support. The upper surface of one end of the triangular steel 6 along the first direction is provided with a driving component, which is used to drive the pressing frame 5 to press the purification box 4.

[0025] like Figure 1 and Figure 4 As shown, the door 2 on the front of the box 1 is fixedly connected by bolts, and its top is sealed by a sealing plate 3 to maintain the airtightness of the purification box 4 during use. The clamping frame 5 is supported by a thirteen-angle steel 6, and the clamping frame 5 can be adjusted up and down by a drive component to clamp and release the purification box 4, which facilitates quick disassembly and installation of the purification box 4 and improves work efficiency.

[0026] The upper surfaces of the front and rear ends of the triangular steel 6 are fixedly connected with hinge bolts 7. The clamping frame 5 includes a rocker shaft 8 inserted inside it and cams 9 fixedly connected to the two ends of the rocker shaft 8. The top of the hinge bolt 7 extends into the interior of the clamping frame 5 and is sleeved on the surface of the rocker shaft 8.

[0027] like Figure 3 and Figure 4 As shown, when the rocker shaft 8 rotates to the left and right, the protrusion 9 on its surface presses against the inner top wall of the cavity of the clamping frame 5, causing the clamping frame 5 to press against the purification box 4, which facilitates quick clamping operation. When the rocker shaft 8 rotates to the right and left, the protrusion 9 does not contact the inner top wall of the cavity, which facilitates disassembly of the purification box 4.

[0028] like Figure 6 As shown, a nut is provided on the surface of the hinge bolt (7) and is used in conjunction with the clamping frame (5). When the screw part of the hinge bolt is rotated, the clamping frame 5 can be adjusted to move up and down and fixed by the nut, so as to facilitate the adjustment of the appropriate clamping distance as needed.

[0029] The driving component includes a crossbar 18 fixedly connected to the upper surface of the front end of the triangular steel 6, a driving block 10 disposed inside the crossbar 18, a driving rod 11 disposed at the output end of the driving block 10, a driving rod 12 and a driving rod 19 meshing with the bottom end of the driving rod 11, and a driving rod 13 meshing with the end of the driving rod 12 and the driving rod 19 away from the driving rod 11. The left and right ends of the crossbar 18 are sleeved on the surface of the rocker shaft 8 through protrusions. Gears 14 are provided inside the protrusions and on the surface of the rocker shaft 8. The gears 14 mesh with the top end of the driving rod 13.

[0030] like Figure 5 As shown, starting the drive block 10 (powered by a motor) drives the drive rod 11 to rotate. Since the drive rods 12 and 19 are meshed with the bottom of the drive rod 11, and the gear 14 is meshed with the top of the drive rod 13, they are driven to rotate synchronously. When the drive block 10 rotates forward, the two rocker shafts 8 rotate in the middle. When the drive block rotates in reverse, the rocker shafts 8 rotate to both sides. When disassembly or assembly is required, the rocker shafts 8 operate synchronously, which can greatly improve the work efficiency of the staff and reduce the labor intensity of the staff.

[0031] A sleeve 16 is fixedly connected to one end of the rocker shaft 8 along the first direction. A handle 17 is inserted into the inside of the sleeve 16. A limit groove 15 is opened on one side of the clamping frame 5 along the first direction and is adapted to the handle 17.

[0032] like Figure 2 As shown, when the rocker shaft 8 rotates to both sides, the handle 17 can move back and forth inside the sleeve 16, so that the handle 17 abuts against both sides of the purification box 4, which facilitates further limiting its position and maintaining its stability during use. When the handle 17 is not in use, the rocker shaft 8 can rotate 90° to the center so that the handle can be inserted into the limiting groove 15, which facilitates its retraction and reduces the impact on the installation of the purification box 4.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0034] In this invention, the working steps of the device are as follows:

[0035] In use, the purification box 4 is installed between the sealing plate 3 and the pressing frame 5. The handle 17 is stretched in the first direction so that one end is tightly against the sleeve 16. Then, the drive block 10 is activated. With the cooperation of the drive rod 11, drive rod 2 12, drive rod 13 and drive rod 4 19 and the gear 14, the rocker shaft 8 is synchronously rotated to the left and right, so that the protrusion 9 on its surface abuts against the pressing frame 5 and the inner top wall of the cavity, driving the pressing frame 5 to move upward and press against the purification box 4. Then, push the handle 17 so that one end moves to both sides of the purification box 4. When disassembling, the operation is reversed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
