Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a manual switch device for a water-saving valve. Background Technology

[0002] Water-saving valves are valves that meet the required functions, have valve body strength and sealing performance that meet standard requirements, and can promote water system leakage reduction and lower operating energy consumption. They are usually used in conjunction with plumbing equipment and sanitary ware such as faucets and urinal flushing valves to achieve the purpose of efficient water saving. When manually opening and closing water-saving valves, a lot of force is often required, which may result in the valve not closing tightly.

[0003] Chinese patent CN221583489U discloses a novel valve switching device. This device adjusts the position of each valve claw on the positioning claw hole so that the anti-slip texture of each valve claw contacts the valve. A rotating force rod transmits torque to each valve claw to open the valve, thereby opening valves of different sizes.

[0004] However, the aforementioned patent requires frequent tightening of the nut when adjusting the position of the valve claw, and the fact that there are four valve claws increases the complexity and time cost of operation in actual use. Furthermore, the aforementioned patent is not convenient for operating valves at higher positions, thus limiting its application. Utility Model Content

[0005] The purpose of this invention is to provide a manual switch for a water-saving valve, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A manual switch for a water-saving valve includes a disc. Four through slots are coaxially arrayed on the surface of the disc. Threaded rods are rotatably mounted inside the slots. Nut seats are mounted on the outer surfaces of the threaded rods, and pawls are connected to the lower surfaces of the nut seats. A drive mechanism capable of simultaneously rotating the four threaded rods is provided on the lower surface of the disc. A hollow rod is mounted on the upper surface of the disc. A mounting block is mounted on the top of the hollow rod via a height adjustment mechanism. Applying force rods are provided on both sides of the mounting block.

[0008] As can be seen, by setting up the drive mechanism, four threaded rods can be driven to rotate simultaneously, which in turn can drive four nut seats to move simultaneously along the length of the threaded rods, achieving the purpose of simultaneously adjusting the position of the four valve claws. Therefore, when using valves of different sizes, it can be quickly adjusted to the corresponding size, reducing the complexity of operation and time cost. Furthermore, by setting up the height adjustment mechanism, the height of the lever can be adjusted, thereby enabling operation of valves at higher positions, providing high flexibility.

[0009] Furthermore, the drive mechanism includes a groove formed on the lower surface of the disc, a first rotating shaft is rotatably mounted inside the groove, a drive bevel gear is sleeved on the outer surface of the first rotating shaft, and the ends of four threaded rods all penetrate into the groove and are mounted with driven bevel gears, and the drive bevel gears are meshed with the driven bevel gears.

[0010] Furthermore, the height adjustment mechanism includes an adjustment rod inserted inside the hollow rod, and a mounting block is installed on the top of the adjustment rod. The outer surface of the adjustment rod has multiple adjustment holes along its height direction, and bolts are installed on the outer surface of the hollow rod.

[0011] Furthermore, mounting slots are provided on both sides of the mounting block, and the force-adding rod is rotatably installed in the mounting slot through the second rotating shaft. Insertion holes are provided on the inner wall of the mounting slot, and a fixing mechanism that engages with the insertion holes is provided inside the force-adding rod.

[0012] Furthermore, the fixing mechanism includes an inner cavity formed inside the force-adding rod, an insert rod disposed inside the inner cavity, a slider slidably mounted on the outer surface of the force-adding rod, the slider being connected to the insert rod, and a spring disposed inside the inner cavity, with both ends of the spring abutting against the inner wall of the inner cavity and the insert rod, respectively.

[0013] Furthermore, a limit groove is provided on the inner wall of the hollow rod, and a limit strip is provided on the outer surface of the adjusting rod, with the limit strip set in the limit groove.

[0014] Furthermore, the inner wall of the mounting slot is provided with two insertion holes, and the included angle between the two insertion holes is 90 degrees.

[0015] Furthermore, a rubber pad is provided on the outer surface of the extension rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model, through the setting of the drive mechanism, can simultaneously drive four threaded rods to rotate, thereby driving four nut seats to move simultaneously along the length direction of the threaded rods, achieving the purpose of simultaneously adjusting the position of the four live claws. Therefore, when using valves of different sizes, it can be quickly adjusted to the corresponding size, reducing the complexity of operation and time cost.

[0018] 2. This utility model, through the setting of a height adjustment mechanism, allows for adjustment of the height of the force-adding rod, thereby enabling operation of valves at higher positions, providing high flexibility.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0029] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0030] Please see Figures 1-5 This utility model provides a manual switch device for a water-saving valve, comprising a disc 100. Four through slots 101 are coaxially arrayed on the surface of the disc 100. Threaded rods 102 are rotatably mounted inside the through slots 101. Nut seats 103 are mounted on the outer surface of the threaded rods 102. A movable claw 104 is connected to the lower surface of the nut seats 103. A drive mechanism 200 capable of simultaneously rotating the four threaded rods 102 is provided on the lower surface of the disc 100. A hollow rod 105 is mounted on the upper surface of the disc 100. A mounting block 106 is mounted on the top of the hollow rod 105 via a height adjustment mechanism 300. Applying rods 107 are provided on both sides of the mounting block 106.

[0031] In use, first, according to the size of the valve, drive the four threaded rods 102 to rotate simultaneously via the drive mechanism 200. Since the inner wall of the through groove 101 limits the nut seat 103, the rotation of the threaded rods 102 can drive the nut seat 103 to move along its length, so that the four maneuvering claws 104 can simultaneously approach or move away from the center of the disc 100, achieving the purpose of synchronous adjustment. After the position of the maneuvering claws 104 is adjusted, they are locked onto the valve, and then the lever 107 is rotated. When operating valves at higher positions, the distance between the lever 107 and the disc 100 can be adjusted simply by using the height adjustment mechanism 300, without the need for climbing tools, making it highly flexible.

[0032] Specifically, the drive mechanism 200 includes a groove 201 formed on the lower surface of the disc 100. A first rotating shaft 202 is rotatably mounted inside the groove 201. A drive bevel gear 203 is sleeved on the outer surface of the first rotating shaft 202. The ends of four threaded rods 102 all penetrate into the groove 201 and are equipped with driven bevel gears 204. The drive bevel gears 203 and driven bevel gears 204 are meshed together. When the first rotating shaft 202 is turned, the drive bevel gears 203 can be rotated. Since the four driven bevel gears 204 are all meshed with the drive bevel gears 203, the purpose of driving the four threaded rods 102 to rotate simultaneously can be achieved. It is worth noting that the end of the first rotating shaft 202 does not extend to the outside of the groove 201, so as to reduce the contact between the first rotating shaft 202 and the valve when opening and closing the valve.

[0033] Specifically, the height adjustment mechanism 300 includes an adjustment rod 301 inserted inside the hollow rod 105, and a mounting block 106 is installed on the top of the adjustment rod 301. The outer surface of the adjustment rod 301 has multiple adjustment holes 302 along its height direction. Bolts 303 are installed on the outer surface of the hollow rod 105. The adjustment rod 301 can extend and retract inside the hollow rod 105. After the bolts 303 are screwed into the adjustment holes 302, the position of the adjustment rod 301 can be fixed. Therefore, the purpose of adjusting the height of the extension rod 107 can be achieved simply by screwing the bolts 303 into the appropriate adjustment holes 302.

[0034] Specifically, mounting slots 400 are provided on both sides of the mounting block 106. The extension rod 107 is rotatably mounted in the mounting slot 400 via the second rotating shaft 401. The inner wall of the mounting slot 400 is provided with an insertion hole 402. The extension rod 107 is provided with a fixing mechanism 500 that engages with the insertion hole 402. Since the extension rod 107 can be flipped, it can be unfolded when in use and folded when not in use, reducing space occupation and making it easy to carry and store. The fixing mechanism 500 includes an inner cavity 501 formed inside the force-adding rod 107. An insert rod 502 is disposed inside the inner cavity 501. A slider 503 is slidably mounted on the outer surface of the force-adding rod 107, and the slider 503 is connected to the insert rod 502. A spring 504 is disposed inside the inner cavity 501, with both ends of the spring 504 abutting against the inner wall of the inner cavity 501 and the insert rod 502, respectively. When the slider 503 is slid, it causes the insert rod 502 to compress the spring 504 and be pulled out from the insertion hole 402. At this time, the force-adding rod 107 is released from fixing and can be flipped. When the insert rod 502 is reinserted into the insertion hole 402, it can be fixed again. The inner wall of the mounting groove 400 is provided with two insertion holes 402, with an included angle of 90 degrees. Due to the two insertion holes 402, the force-adding rod 107 can be fixed in a vertical or horizontal state, improving the structural stability of the force-adding rod 107 in both states.

[0035] Specifically, a limiting groove 600 is provided on the inner wall of the hollow rod 105, and a limiting strip 601 is provided on the outer surface of the adjusting rod 301. The limiting strip 601 is set in the limiting groove 600. The limiting groove 600 and the limiting strip 601 limit the adjusting rod 301, prevent the angle of the adjusting rod 301 from deflecting, and ensure that the adjusting hole 302 is always at the angle corresponding to the bolt 303, thus improving the adjustment efficiency of the height of the force-adding rod 107.

[0036] Specifically, the outer surface of the extension rod 107 is equipped with a rubber pad. The rubber pad not only protects the hand and reduces hand discomfort, but also increases friction and reduces the chance of slipping.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
