DETAILED DESCRIPTION

[0028] 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.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 5 , a portable hand-held valve quick closing tool, comprising:

[0031] Handle 1 and clamp 2;

[0032] The clamp 2 is connected to the handle 1;

[0033] The handle 1 includes a first support rod 101 and a second support rod 102;

[0034] The clamp 2 includes a first clamping plate 201 and a second clamping plate 202;

[0035] The first support rod 101 is fixedly connected to the first clamping plate 201;

[0036] A first connecting rod 4 connected to the second clamping plate 202;

[0037] A second connecting rod 5 connected to the first clamping plate 201;

[0038] The first connecting rod 4 and the second connecting rod 5 are fixedly connected.

[0039] The first clamping plate 201 and the second clamping plate 202 are both fixedly connected with the connecting plate 3, the first connecting rod 4 and the second connecting rod 5 are both rotatably connected to the connecting plate 3, the first connecting rod 4 is provided with a threaded hole 401, the second connecting rod 5 is fixedly connected with a threaded rod 501, and the threaded rod 501 matches the threaded hole 401.

[0040] A first magnet 4011 is fixedly connected in the threaded hole 401 , and a second magnet 5011 is fixedly connected to the threaded rod 501 . The first magnet 4011 and the second magnet 5011 attract each other.

[0041] Reference Figure 1-Figure 4 When closing the valve, the staff will respectively attach the first clamping plate 201 and the second clamping plate 202 to the hexagonal axis of the valve body. After they are tightly attached, the staff can manually or use tools to rotate the second connecting rod 5 and connect it to the first connecting rod 4;

[0042] Reference Figure 3 , Figure 4During the rotation of the second connecting rod 5, the second connecting rod 5 will drive the threaded rod 501 to rotate, and the threaded rod 501 will be screwed into the threaded groove 401 of the first connecting rod 4. At this time, the first connecting rod 4 will be fixedly connected to the second connecting rod 5, and the first clamping plate 201 and the second clamping plate 202 will clamp the shaft of the valve body. At this time, the handle 1 can be rotated to quickly close the valve body.

[0043] Reference Figure 3-Figure 5 It should be noted that when the threaded rod 501 is screwed into the threaded groove 401, the first magnet 4011 will be attracted to the second magnet 5011. The attraction between the first magnet 4011 and the second magnet 5011 further improves the stability of the connection between the first clamping plate 201 and the second clamping plate 202, thereby preventing the first clamping plate 201 and the second clamping plate 202 from loosening when the valve body is closed.

[0044] When the device closes the valve body, the clamp 2 is divided into a first clamping plate 201 and a second clamping plate 202 that can be movably connected, so that it can be used for valves of different sizes and has wider applicability. At the same time, the retractable handle 1 saves the staff more effort when rotating to close the valve body.

[0045] The first connecting rod 4 and the second connecting rod 5 are both fixedly connected to the limiting plate 6 .

[0046] Reference Figure 2 , Figure 5 The first support rod 101 is fixedly connected with a screw rod 8, and the second support rod 102 is threadedly connected to the screw rod 8.

[0047] Reference Figure 2 , Figure 5 During use, when encountering a valve that is difficult to turn, the staff can manually rotate the second connecting rod 5. At this time, the second connecting rod 5 will be rotated along the screw 8. At this time, the overall length of the handle 1 will become longer. According to the lever principle, the handle 1 becomes longer, and the staff can operate it more labor-saving.

[0048] Anti-slip patterns 7 are provided on the first clamping plate 201 and the second clamping plate 202 .

[0049] The first support rod 101 and the second support rod 102 are also provided with anti-slip grooves 7 .

[0050] Reference Figure 1 By setting the anti-slip grooves 7 on the first clamping plate 201 and the second clamping plate 202, the friction between the clamp 2 and the valve body can be effectively improved, thereby improving the stability of the clamp 2 during the clamping process.

[0051] The anti-slip grooves 7 provided on the first support rod 101 and the second support rod 102 can increase the friction between the worker's hand and the handle 1 , thereby facilitating the worker to rotate the handle 1 .

[0052] The above 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 substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
