DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a precision screen, comprising a screen body 1, the inner wall of the screen body 1 is provided with a cleaning mechanism 2 for convenient cleaning, the top of the screen body 1 is provided with a flushing mechanism 4 for flushing and cleaning, the top of the cleaning mechanism 2 is provided with a disassembly mechanism 3 for disassembly and replacement, the end of one side of the screen body 1 is provided with a limiting mechanism 5 for limiting and fixing, the cleaning mechanism 2 comprises a first connecting plate 21, and the first connecting plate 21 is slidably connected to the inside of the screen body 1;

[0029] A second connecting plate 26 is clamped on one side of the first connecting plate 21, and an adapter plate 24 is clamped inside the first connecting plate 21 and the second connecting plate 26. Insert blocks 27 are fixedly installed at both ends of the top of the second connecting plate 26, and an adapter seat 28 is fixedly installed at both ends of the top of the first connecting plate 21. The insert blocks 27 are inserted into the inside of the adapter seat 28, and a soft brush plate 25 is fixedly installed on the bottom of the adapter plate 24.

[0030] When brushing:

[0031] The external driving member is directly installed and connected by the fixed plate 23, and then the driving force will directly drive the first connecting plate 21 to move through the fixed plate 23. When the first connecting plate 21 moves, it can drive the soft-bristle brush plate 25 at the bottom to move back and forth through the adapter plate 24, thereby realizing the cleaning work by grabbing and brushing.

[0032] Among them, a fixing plate 23 is fixedly installed at the center of the top of the first connecting plate 21, and sliders 22 are fixedly installed at both ends of the first connecting plate 21. A sliding groove 6 is opened on the inner wall of the mesh body 1, and the slider 22 is slidably connected to the inside of the sliding groove 6, which is convenient for supporting the first connecting plate 21 and can assist it in sliding to achieve displacement.

[0033] Based on the above, during horizontal sliding, the slider 22 will slide synchronously inside the slide groove 6, thereby ensuring the stability of horizontal movement.

[0034] Preferably, the disassembly and assembly mechanism 3 includes a connecting component, a supporting component and a locking component. The connecting component is arranged at both ends of the top of the first connecting plate 21, the supporting component is arranged at both ends of the top of the second connecting plate 26, and the locking component is arranged on the outside of the connecting component.

[0035] like Figure 3As shown, the connecting assembly includes a first vertical plate 31 and a threaded rod 32. The first vertical plate 31 is fixedly installed at both ends of the top of the first connecting plate 21, and the threaded rod 32 is rotatably connected to the inner wall of the first connecting plate 21 to assist in locking and fixing.

[0036] like Figure 3 As shown, the support assembly includes a second vertical plate 33 and a groove 34. The second vertical plate 33 is fixedly installed at both ends of the top of the second connecting plate 26. A groove 34 is opened on one side of the second vertical plate 33 to cooperate with the locking assembly for positioning and fixing.

[0037] like Figure 3 As shown, the locking assembly includes a protrusion 36, which is inserted into the groove 34. A baffle 35 is fixedly installed at one end of the protrusion 36. The baffle 35 is sleeved on the outside of the threaded rod 32. The outer side of the threaded rod 32 is threadedly connected with a threaded sleeve 37 to achieve a stable connection between the first vertical plate 31 and the second vertical plate 33.

[0038] The picture shows the installation status;

[0039] When disassembling:

[0040] The threaded sleeve 37 is directly rotated counterclockwise to release the tight state of the baffle 35 by the threaded sleeve 37, and then the baffle 35 is pulled to one side, and the baffle 35 drives the protrusion 36 to move and make the protrusion 36 disengage from the inside of the groove 34. At this time, the threaded rod 32 is rotated to the opposite direction, and then the second connecting plate 26 is directly pulled to move, and the second connecting plate 26 drives the plug 27 to disengage from the adapter seat 28. Then, after the adapter plate 24 is taken out, the soft brush plate 25 will be driven to disengage from the first connecting plate 21 to complete the removal operation;

[0041] When installing:

[0042] After the new soft-bristle brush plate 25 is stuck inside the first connecting plate 21, the second connecting plate 26 is stuck on its outside. At this time, the insert block 27 is inserted into the inside of the adapter seat 28. After the threaded rod 32 is rotated to the state shown in the figure, the threaded sleeve 37 is rotated clockwise to synchronously push the baffle 35 to drive the protrusion 36 to be inserted into the inside of the groove 34, and then the baffle 35 is tightened by the threaded sleeve 37.

[0043] Furthermore, the flushing mechanism 4 includes a sliding component and a water spray component. The sliding component is arranged on the top of the screen body 1, and the water spray component is arranged on the inner side of the sliding component.

[0044] like Figure 4 As shown, the sliding assembly includes a fixed block 41, which is fixedly installed at the four ends of the top of the mesh body 1. A sliding rod 42 is fixedly installed on the inner side of the fixed block 41, and a sliding sleeve 43 is slidably connected to the outer side of the sliding rod 42, which is beneficial to play a role in auxiliary movement and load-bearing.

[0045] like Figure 4 As shown, the water spray assembly includes a connecting pipe 44, the inner side of the sliding sleeve 43 is rotatably connected with the connecting pipe 44, one end of the connecting pipe 44 is connected to a hose 45, and one side of the connecting pipe 44 is connected to a nozzle 46, which can play the role of water delivery and water spraying.

[0046] The mounting frame 51 can directly and electrically drive the two sets of sliding sleeves 43 on the outside of the sliding rod 42 to realize the connection pipe 44 moving through the nozzle 46 to spray water, flush and clean, and the hose 45 is connected to the position water pump to realize auxiliary water supply operation. When the angle of the spray, flush and clean needs to be adjusted, the connection pipe 44 can be directly rotated to the required angle, and finally the limiting mechanism 5 completes the locking and limiting of it.

[0047] Furthermore, the limiting mechanism 5 includes a mounting frame 51, which is fixedly mounted on the outside of the sliding sleeve 43. A spring 52 and a telescopic rod 53 are fixedly mounted on the top of the mounting frame 51. The spring 52 is located on the outside of the telescopic rod 53. A tooth plate 54 is fixedly mounted on the top of the spring 52 and the telescopic rod 53. A gear 55 is meshed with the top of the tooth plate 54. The gear 55 is fixedly mounted on the outside of the connecting pipe 44, which is conducive to the locking work of the connecting pipe 44 after rotation, so as to ensure stable flushing operation after the angle is adjusted.

[0048] When rotating the connecting tube 44, the tooth plate 54 needs to be pressed downward. At this time, the tooth plate 54 disengages from the gear 55, and compresses the spring 52 and the telescopic rod 53. When the connecting tube 44 rotates, it will synchronously drive the gear 55 to rotate together. After the adjustment is completed, the downward pressure on the tooth plate 54 can be released, and then the elastic driving force causes the tooth plate 54 to engage the gear 55 to complete the positioning and locking work.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
