DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 5 A labor-saving manual hydraulic valve includes a valve body 1 and an adjusting handle 3, the adjusting handle 3 is connected to the valve body 1 by threads, and also includes: an opening and closing handle 2 is provided on the adjusting handle 3 and is plugged in through a connecting rod; a plug-in hole 13 is provided on the adjusting handle 3 and runs horizontally through the handle end; the opening and closing handle 2 is also provided with a plug-in hole 13; a locking hole 14 is vertically provided on a side where the adjusting handle 3 and the opening and closing handle 2 are horizontally placed and overlapped; a locking rod 12 is plugged in the locking hole 14.

[0028] In the utility model, when the user uses it, he takes out the locking rod 12 and inserts the locking rod 12 into the insertion hole 13. At this time, the locking rod 12 is equivalent to an extended lever, so that the user can rotate the locking rod 12 with a small force to realize the rotation adjustment of the adjustment handle 3.

[0029] When the device is installed in a relatively small space, the locking rod 12 may not be able to rotate due to its length. At this time, the user can open the opening and closing handle 2 to ninety degrees, clamp the opening and closing handle 2 by hand or with a clamping tool such as pliers, and then rotate it to adjust the adjustment handle 3, so that the adjustment handle 3 can be rotated and adjusted more easily.

[0030] When the locking rod 12 is used, it is reinserted into the locking hole 14 so that the locking rod 12 can limit the opening and closing handle 2, so that the opening and closing handle 2 will not be easily opened.

[0031] If the valve body 1 is installed in an inverted position or at another angle, threads and thread grooves may be provided on the locking rod 12 and the locking hole 14 to prevent the locking rod 12 from falling off through threaded connection.

[0032] Embodiment 2:

[0033] Reference Figure 1-Figure 5, which is basically the same as Example 1, and further: a first gear 5 which is concentric with the axis of the adjusting handle 3 is provided on the upper end surface of the locking hole 14, a boss 6 is fixed above the first gear 5, a locking hole 14 is opened on the boss 6, a second gear 7 is meshed with one side of the first gear 5, a second handle 8 is provided above the second gear 7, a component protective shell 15 is provided above the valve body 1, a slide bar 11 is fixed on the inner wall of the component protective shell 15, a locking block 10 with small teeth on the inner wall of the slide bar 11 is sleeved, an adjusting nut 9 is threadedly connected to the locking block 10, the adjusting nut 9 is fixedly rotated on the outer wall of the component protective shell 15, and a pressure regulating spring 4 is fixedly connected to the adjusting handle 3.

[0034] In this experimental model, the user can rotate the second handle 8 to drive the second gear 7 below to rotate, the second gear 7 drives the first gear 5 meshing with it to rotate, and the first gear 5 drives the boss 6 thereon to rotate, thereby adjusting the locking hole 14 on the boss 6. When the locking hole 14 on the boss 6 corresponds to the locking hole on the adjustment handle 3, the locking rod 12 can be inserted, so that the adjustment handle 3 and the first gear 5 move synchronously.

[0035] The user turns the adjusting nut 9 to make the locking block 10 move forward or backward along the direction of the sliding rod 11. When the locking block 10 moves forward to touch the second gear 7, the small protruding teeth on the inclined surfaces of the inner walls on both sides of the locking block 10 will press against the teeth on the second gear 7, thereby locking the second gear 7, and then locking the first gear 5 and the boss 6, and cooperating with the insertion of the locking rod 12 to lock the adjusting handle 3.

[0036] The second gear 7 is much smaller than the first gear 5 , so that the user can rotate the second handle 8 with less force and can adjust the angle of the locking hole 14 on the boss 6 more finely.

[0037] The component protection shell 15 can isolate the locking component from the valve body 1, protect the locking component, and prevent the locking component from being exposed, corroded, and rusted, which may cause the gear shaft to be difficult to rotate.

[0038] When the user uses it, he first takes the locking rod 12 out of the locking hole 14, inserts it into the plug-in hole 13, and then rotates it to adjust the adjusting handle 3. As the adjusting handle 3 rotates, the pressure-adjusting spring 4 thereon is compressed to generate pressure inside the valve body 1. When the adjusting handle 3 is rotated to make the pressure reach a preset value, the user adjusts the locking hole 14 on the boss 6 by rotating the second handle 8 so that the locking hole 14 on the boss 6 is aligned with the adjusting hole 14 on the adjusting handle 3, and then inserts the locking rod 12. Then the user rotates the adjusting nut 9 until the locking block 10 is stuck with the second gear 7, and the adjusting handle 3 can be locked.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
