As shown in fig. 1 to 10, a silent check mechanism includes a check rack 1 and a silent check block, the silent check block includes a sliding block 2, the bottom of the sliding block 2 is provided with engaging teeth, a sliding groove 12 is formed in the sliding block 2 along a direction perpendicular to the engaging teeth, a check slider 3 is slidably disposed in the sliding groove 12, a meshing protrusion is disposed at the bottom of the check slider 3, wherein the structure of the meshing protrusion is the same as and corresponds to the engaging teeth, and the check slider 3 moves along the sliding groove 12 to make the meshing protrusion coincide with or be dislocated from the engaging teeth to realize the power connection or disconnection between the check rack 1 and the sliding block 2. In the scheme, a mute check block is arranged on a check rack 1 in a sliding manner, the mute check block and the check rack 1 can be used as a fixed end or a movable end, the mute check block is taken as an example for illustration by taking the mute check block as a driving part, meshing teeth arranged at the bottom of a sliding block 2 are meshed with teeth on the check rack 1 when the mute check block moves along the positive direction of the check rack 1, the teeth on the check rack 1 adopt right-angled trapezoid-shaped teeth, and the meshing teeth are also in a right-angled trapezoid-shaped structure, so that the meshing teeth are meshed with the teeth on the check rack 1 and cannot move continuously under the blocking of a straight edge, when the mute check block moves reversely, the meshing teeth are matched with inclined edges of the teeth on the check rack 1, the top surfaces of the meshing teeth are abutted against tooth crest surfaces on the check rack 1, and the mute check block moves continuously to enable the sliding block 2 to move in a sliding chute 12, therefore, the meshing protrusion of the meshing teeth and the non-return sliding block 3 is dislocated, the meshing condition of the meshing teeth and the teeth on the non-return rack 1 is interrupted after the dislocation, and the meshing teeth and the teeth on the non-return rack 1 cannot be meshed, so that the sliding block 2 and the non-return rack 1 always keep a relative sliding state and are always in a surface friction state during sliding, and the generated noise is low.

Furthermore, the section of the sliding groove 12 is in a shape of a Chinese character 'tu', the section of the non-return sliding block 3 is in a shape of a Chinese character 'tu' matched with the section of the sliding groove 12, and the two ends of the non-return sliding block 3 or the two ends of the sliding groove 12 are provided with the limiting structures 8, and the limiting structures 8 limit the sliding positions of the non-return sliding block 3. The sliding groove 12 is set to be in a convex structure, the non-return sliding block 3 is also in a convex structure, so that the non-return sliding block 3 can only move along the sliding groove 12 in the sliding groove 12, the movement in other directions is limited, the limit structure 8 is arranged for limiting the moving position of the non-return sliding block 3 in the sliding groove 12, the non-return sliding block 3 is positioned at two moving limit positions in the sliding groove 12, so that the meshing protrusion and the meshing tooth are staggered or overlapped, the sliding block 2 cannot be meshed with the non-return rack 1 during dislocation, and the sliding block 2 and the non-return rack 1 meet the meshing condition only when the meshing protrusion and the meshing tooth are overlapped.

Furthermore, silence ends contrary piece still includes mounting panel 4, mounting panel 4 be "Contraband" type structure, mounting panel 4 in be provided with fixed block 5, mounting panel 4 cover establish on contrary rack 1, and sliding block 2 sets up between contrary rack 1 and fixed block 5, sliding block 2 and fixed block 5 between be provided with reset structure. The mounting plate 4 is used for connecting the mute check block to the check rack 1 to realize relative movement, the mounting plate 4 is of an open groove-shaped structure, the check rack 1 is arranged in the groove and then forms a square-shaped structure with the mounting plate 4 by arranging a fixing block 5, and thus the check rack 1 and the sliding block 2 are arranged in the square-shaped structure and have elasticity to press the sliding block 2 to the check rack 1 by arranging a reset structure, so that power for meshing the check rack 1 and the sliding block 2 is formed.

Further, reset structure include reset screw 6, reset

screw

6 and 2 threaded connection of sliding block, just be provided with the guiding hole on the fixed block 5, reset screw 6 passes in the guiding hole, the cover is equipped with reset spring 7 on the reset screw 6, reset spring 7 is located between sliding block 2 and the fixed block 5, and reset spring 7 is in the state that is compressed all the time, makes sliding block 2 keep pressing to backstop rack 1.

Furthermore, a mounting hole is formed in the end face of the top of the engaging protrusion, and an adsorption magnet 9 is arranged in the mounting hole. In the scheme, the non-return rack 1 is made of a metal material which can be adsorbed by a magnet 9, when the meshing teeth of the sliding block 2 relatively move between the non-return rack 1 and the sliding block 2 slide out of the teeth of the non-return rack 1, when the meshing tooth tops of the sliding block 2 and the tooth tops of the non-return rack 1 move to be opposite to each other, the magnet 9 arranged on the non-return sliding block 3 and the non-return rack 1 are adsorbed together, because the non-return sliding block 3 can move in the sliding block 2, when the sliding block 2 continues to move, the non-return sliding block 3 moves in a lagging way due to the adsorption force of the magnet 9, so that the meshing teeth of the sliding block 2 and the meshing protrusions of the non-return sliding block 3 are dislocated until the non-return sliding block 3 moves to a limit end, then the sliding block 2 drives the non-return sliding block 3 to overcome the adsorption force of the magnet 9 to continue to move, at the moment, because the meshing protrusions of the non-return sliding block 3 and the meshing teeth of the sliding block 2 are dislocated, the sliding block 2 and the non-return rack 1 are broken, the meshing teeth of the sliding block 2 can not be normally meshed with the teeth of the non-return rack 1, and are always in a sliding state with the tooth tops opposite to each other.

Further, the tooth top of the non-return rack 1 is provided with an embedding hole 10, and a second magnet 11 is arranged in the embedding hole 10. This scheme is as the supplement to above-mentioned scheme, and non-return rack 1 in this scheme can not adopt metal material, through set up second magnet 11 on non-return rack 1, and second magnet 11 fastens in inlaying hole 10, realizes the dislocation of sliding block 2 and non-return slider 3 through the absorption of second magnet 11 and magnet 9.

Furthermore, the limiting structure 8 is a limiting block, and the limiting block and the non-return sliding block 3 are integrated or fixed on the non-return sliding block 3 through a bolt. When stopper and non-return slider 3 structure as an organic whole, can only a stopper and non-return slider 3 an organic whole, another stopper need pass through the bolt fastening on non-return slider 3, and the stopper forms spacingly with the structure that non-return slider 3 formed the T type, and in addition, the stopper can also be fixed at the both ends of spout 12, can realize spacingly equally.

Furthermore, the meshing teeth are provided in plurality, the meshing protrusions of the non-return sliding block 3 are provided in plurality, and the tooth tops of the meshing teeth and the tops of the meshing protrusions are in the same plane.
