DETAILED DESCRIPTION

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] The embodiment of the present application discloses a hand wheel auxiliary tool. Referring to Figure 1 and Figure 2 , the auxiliary tool comprises an operating rod 1 and an extension rod 2 fixed to the side wall of the operating rod 1. Two extension rods 2 are fixed, and are symmetrically fixed to the outer wall of the operating rod 1. The operating rod 1 and the extension rod 2 are perpendicular, thereby forming a structure similar to a cross.

[0030] The operating rod 1 is provided with two first positioning columns 3, which are located on both sides of the extension rod 2; the extension rod 2 is provided with a second positioning column 4; the two first positioning columns 3 and the two second positioning columns 4 enclose a clamping space for clamping the valve hand wheel. After the clamping space clamps the valve hand wheel, the valve hand wheel can be driven to rotate by rotating the operating rod 1.

[0031] With reference to Figure 2 and Figure 3 , the first positioning column 3 and the second positioning column 4 are both in a cylindrical structure, the upper end of the first positioning column 3 is fixed with an adjusting ring 5, and the adjusting ring 5 is slidingly sleeved on the outer wall of the operating rod 1. The adjusting ring 5 is provided with a positioning pin 6, and the operating rod 1 is provided with a positioning groove 15 which is spaced apart along the length direction of the operating rod 1; the position of the adjusting ring 5 is adjusted, and then the position of the first positioning column 3 is adjusted. The positioning pin 6 is inserted into the positioning groove 15, so as to position the adjusting ring 5.

[0032] In a further embodiment, the positioning pin 6 is slidingly arranged on the outer wall of the adjusting ring 5, and an elastic element 7 is arranged between the positioning pin 6 and the adjusting ring 5; under the action of the elastic element 7, the positioning pin 6 can be driven to be inserted into the positioning groove 15. When it is necessary to adjust the position of the adjusting ring 5, the positioning pin 6 is slid out, so as to adjust the adjusting ring 5, and the elastic element 7 provides the force for the positioning pin 6 to be re-inserted into the positioning groove 15. Preferably, the elastic element 7 is a spring which is sleeved on the outer wall of the positioning pin 6, one end of the spring is connected to the outer wall of the adjusting ring 5, and the other end of the spring is connected to the end of the positioning pin 6. When the positioning pin 6 is separated from the positioning groove 15, the spring is in a stretched state. Further, in order to improve the stability between the adjusting ring 5 and the operating rod 1, a limiting block 14 is fixed on the inner wall of the adjusting ring 5, and a limiting groove 13 for sliding the limiting block 14 is formed on the outer wall of the operating rod 1; when the adjusting ring 5 is slidingly adjusted, the limiting block 14 can slide in the limiting groove 13.

[0033] In a further embodiment, the extension rod 2 is internally hollow, and a threaded rod 8 is threadedly connected to the extension rod 2. The threaded rod 8 is rotatably arranged through the upper end of the second positioning column 4, and a guide element 9 is arranged between the extension rod 2 and the second positioning column 4. The upper end of the second positioning column 4 is in a ring block structure, the threaded rod 8 and the upper end of the second positioning column 4 can be rotatably connected by a bearing or the like; the guide element 9 connects the extension rod 2 and the second positioning column 4 together, so as to limit the rotation of the second positioning column 4. When the threaded rod 8 is threadedly advanced or retreated on the extension rod 2, the second positioning column 4 is simultaneously driven to move, so as to adjust the size of the clamping space.

[0034] With reference to Figure 2 and Figure 3The guide piece 9 comprises a guide strip 91 fixed to the upper end of the second positioning column 4, and a plurality of guide strips 91 can be arranged. The outer wall of the extension rod 2 is provided with a guide groove 10 for sliding insertion of the guide strip 91. When the threaded rod 8 drives the second positioning column 4 to move, the guide strip 91 synchronously slides in the guide groove 10, and the second positioning column 4 is limited from rotating by the guide strip 91.

[0035] In a further embodiment, the operating rod 1 is hingedly connected with an adjusting rod 11 at the end away from each other. The adjusting rod 11 is connected to the end of the operating rod 1 by a pin shaft or the like. The adjusting rod 11 can be rotated to be in a same straight line with the operating rod 1; the adjusting rod 11 can also be rotated to be perpendicular to the operating rod 1 in a direction away from the first positioning column 3. When the operating space is sufficient, the adjusting rod 11 is rotated to be in the same straight line with the operating rod 1, so as to operate. When the operating space is small, the adjusting rod 11 is rotated to be perpendicular to the operating rod 1, and then the operation is performed.

[0036] The adjusting rod 11 is provided with a limiting piece 12. When the adjusting rod 11 is rotated to be in the same straight line with the operating rod 1, the limiting piece 12 can position the adjusting rod 11, so that the adjusting rod 11 cannot be rotated. The limiting piece 12 comprises a limiting cylinder 121 threadedly connected to the side wall of the adjusting rod 11. When the adjusting rod 11 and the operating rod 1 are in the same straight line, the limiting cylinder 121 is rotated, so that the limiting cylinder 121 covers the connection between the adjusting rod 11 and the operating rod 1, thereby limiting the rotation of the adjusting rod 11. When the adjusting rod 11 is rotated to be perpendicular to the operating rod 1, the limiting cylinder 121 is rotated, so that the end of the limiting cylinder 121 abuts against the side wall of the operating rod 1, thereby limiting the rotation of the adjusting rod 11, and then the operation of the valve hand wheel is performed, thereby improving the stability of the operation.

[0037] The implementation principle of the hand wheel auxiliary tool in the embodiment is as follows: when the valve hand wheel is driven to rotate, the valve hand wheel is clamped in the clamping space, and then the valve hand wheel can be driven to rotate by operating the operating rod 1, so that the operation is more convenient, and the first positioning column 3 and the second positioning column 4 can be adjusted, so that the clamping space can better adapt to the valve hand wheel, thereby avoiding the slippage.

[0038] The above are the preferred embodiments of the present application, and are not used to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
