Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] A valve regulating structure, such as Figure 2 As shown, the valve includes a valve seat 2, inside which is a valve ball 1, and a valve stem 5 is fixed to the top of the valve ball 1; a pressure plate 3 is provided on the outside of the valve stem 5, the pressure plate 3 is used to fix the packing and increase the internal sealing of the valve, and the pressure plate 3 is connected to the valve seat 2 by bolts 4; the above is the basic structure of the valve, which belongs to the prior art.
[0025] The top end of the valve stem 5 is fixed with an operating component 6 by a nut 51, such as... Figure 1As shown, the operating component 6 includes a fixed plate 61, a folding plate 62, an extension plate 63, and a connecting plate 64. The fixed plate 61 is fixed to the valve stem 5 by a nut 51, and the end of the fixed plate 61 is provided with a connecting plate 64. The side of the connecting plate 64 is provided with two parallel extension plates 63. The folding plate 62 is rotatably connected between the two extension plates 63. In use, the folding plate 62 can be folded out to extend the operating part of the valve adjustment structure, making the operation more labor-saving.
[0026] The bottom end of the connecting plate 64 is fixed with a limiting post 7, and the interior of the connecting plate 64 is provided with a locking component 9; the locking component 9 passes through the limiting post 7, and a limiting groove 32 is formed on the surface of the pressure plate 3; the limiting post 7 is engaged with the limiting groove 32, and a plurality of grooves are evenly distributed on one half of the bottom surface of the limiting groove 32 (exemplary, attached). Figure 1 The black area at the bottom of the middle limiting groove 32 is a recess, which can also be set to one-quarter of the bottom surface of the limiting groove 32 (since a typical valve can be opened or closed by rotating 90°); the recess, in conjunction with the locking assembly 9, is used to lock the operating assembly 6. Specifically, as shown... Figure 3 As shown, the locking assembly 9 includes a push plate 91, a second spring 92, a slide rod 93, and a insert plate 94; the second spring 92 is provided inside the connecting plate 64, and the top end of the second spring 92 is connected to the push plate 91; the push plate 91 extends out of the connecting plate 64, and the side of the push plate 91 is connected to the slide rod 93; the slide rod 93 is inserted into and slidably connected to the limiting post 7, and the bottom end of the slide rod 93 is fixed with the insert plate 94; the insert plate 94 is fitted into the connecting groove. When the valve is opened or closed by rotating the operating component 6, the folding plate 62 is rotated first. When the folding plate 62 rotates, the pressing plate 91 is pushed upward by the restoring force of the second spring 92, which drives the slide rod 93 and the insert plate 94 to move upward synchronously. At this time, the insert plate 94 moves away from the groove. Then, the rotation of the folding plate 62 drives the valve stem 5 to rotate to open or close the valve, or the flow rate is controlled by rotating to a suitable angle. After completion, the folding plate 62 is reset. When the folding plate 62 is reset, the pressing plate 91 is pressed down. When the pressing plate 91 moves down, it compresses the second spring 92, causing the slide rod 93 to drive the insert plate 94 to insert into the corresponding groove, thus locking this state and preventing accidental contact.
[0027] To ensure more stable rotation of the operating component 6, a movable column 8 is fixed to the bottom end of the fixed plate 61, and the movable column 8 is connected to the limiting groove 32; a roller 81 is installed at the bottom end of the movable column 8.
[0028] To restrict and fix the state of the rotating folding plate 62, the operating assembly 6 further includes a positioning rod 65, an operating plate 66, a connecting rod 67, a spring 68, and a positioning groove 69; as Figure 5As shown, the inside of the folding plate 62 is provided with a spring 68, and the two ends of the spring 68 are connected with connecting rods 67; the top end of the connecting rod 67 is fixed with an operation plate 66, and the operation plate 66 extends out of the folding plate 62; the side of the connecting rod 67 is fixed with a positioning rod 65; the inner wall of the extending plate 63 is provided with positioning grooves 69, and the positioning grooves 69 are connected with the positioning rods 65. Among them, the positioning grooves 69 are three, and the folding plate 62 is connected between two extending plates 63; the length of the folding plate 62 is greater than the length of the extending plate 63. As shown in Figure 4 As shown, in the locked state, the folding plate 62 is parallel between the two extending plates 63, and the positioning rod 65 is in the positioning groove 69 at A at this time, and the locking assembly 9 is pressed to be in the locked state at this time. If the folding plate 62 and the extending plate 63 are perpendicular to the valve control, press the operation plate 66 at this time, make the connecting rods 67 close to each other and compress the spring 68, and the two positioning rods 65 move inward until they are separated from the positioning groove 69 at A; after rotating 90°, release the operation plate 66, at this time, the spring 68 pushes the two connecting rods 67 to drive the positioning rod 65 to move under the action of the elastic force, until the positioning rod 65 is inserted into the positioning groove 69 at C, at this time, the folding plate 62 is perpendicular to the extending plate 63 to facilitate the valve control. Similarly, rotate the folding plate 62 by 90° again until the positioning rod 65 is inserted into the positioning groove 69 at B, at this time, the folding plate 62 is on the left side of the extending plate 63, which extends the operation part to facilitate the control. The user can rotate to the appropriate position according to the environment of the valve and the demand of the use habit to use.
[0029] The pressing plate 3 adopts a disc structure, and the surface of the pressing plate 3 is provided with mounting holes 31; the mounting holes 31 are connected with the bolts 4.
[0030] When using this invention, if valve control is required, the locking assembly 9 needs to be released. Simultaneously, the rotation position of the folding plate 62 needs to be determined. For example, if the folding plate 62 needs to be positioned on the left side of the extended plate 63 to extend the operating section, the operating plate 66 needs to be pressed, causing the connecting rods 67 to move closer to each other and compress the first spring 68. The two positioning rods 65 move inward until they disengage from the positioning groove 69 at point A. Pressing the extended section of the folding plate 62 causes it to rotate 180°. Then, the operating plate 66 is released. At this point, the first spring 68, under its elastic force, pushes the two connecting rods 67, causing the positioning rods 65 to move until they insert into the positioning groove 69 at point B. As the folding plate 62 rotates, the pressing plate 91, under the restoring force of the second spring 92, pushes the pressing plate 91 upward, causing the sliding rod 93 and the insert plate 9... 4. Simultaneously move upwards. At this time, the insert plate 94 moves away from the groove, and the locking state of the locking component 9 is released. At this time, the valve stem 5 can be rotated to a suitable angle by rotating the folding plate 62 to realize valve control and adjustment. After reaching the appropriate position, this state is fixed. Simply press the operating plate 66 to make the connecting rods 67 move closer to each other and compress the first spring 68. The two positioning rods 65 move inward until they disengage from the positioning groove 69 at point B, so that the folding plate 62 is reset. Then release the operating plate 66. At this time, the first spring 68 pushes the two connecting rods 67 under the action of elasticity, which drives the positioning rods 65 to move until the positioning rods 65 are inserted into the positioning groove 69 at point A. At this time, as the folding plate 62 rotates, it presses down the pressing plate 91. When the pressing plate 91 moves down, it compresses the second spring 92, so that the sliding rod 93 drives the insert plate 94 to insert into the corresponding groove, thus completing the locking of this state.
