[0042] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0043] like Figures 1 to 3 As shown, according to an embodiment of the present application, a gas regulating valve wrench for an internal combustion engine is proposed, comprising: an operating rod 11 and a clamping plate 12; the clamping plate 12 is arranged on the operating rod 11, and the clamping plate 12 extends along the length direction of the operating rod 11; wherein two clamping grooves 13 are arranged at symmetrical positions of the adjusting screw 14, and the two clamping grooves 13 are located on the same diameter line of the adjusting screw 14, the thickness of the clamping plate 12 is not greater than the width of the clamping groove 13, and the clamping plate 12 can be embedded in the two clamping grooves 13 at the same time.

[0044] The internal combustion engine gas regulating valve wrench provided in the embodiment of the present application includes an operating rod 11 and a clamping plate 12. The clamping plate 12 is arranged on the operating rod 11 along the length direction of the operating rod 11. The length of the clamping plate 12 is not less than the distance between the two clamping grooves 13, and the thickness of the clamping plate 12 is not greater than the width of the clamping groove 13, so that the clamping plate 12 can be embedded in the two clamping grooves 13 on the regulating valve at the same time to fix the clamping plate 12 on the adjusting screw 14. The clamping plate 12 is driven to rotate synchronously by rotating the operating rod 11. The clamping plate 12 is clamped and fixed to the clamping groove 13, so that the adjusting screw 14 can rotate synchronously with the clamping plate 12, and then the adjusting screw 14 is rotated relative to the housing 16 of the regulating valve, so as to realize quick adjustment of the adjusting screw 14, and the operation is convenient and labor-saving. The wrench has a simple overall structure and strong practicality. It is not only suitable for the adjusting screw 14 with a double card slot 13, but also suitable for the adjusting screw 14 with a straight slot, and can meet the operation requirements of all regulating valves during debugging and maintenance; the card plate 12 is directly connected to the operating rod 11, which is convenient for applying force to prevent the wrench from tilting and escaping from the card slot 13 during operation. It has strong operability and can quickly tighten the adjusting screw 14, reducing the difficulty of adjusting the regulating valve and improving the adjustment efficiency of the regulating valve.

[0045] It should be noted that if Figure 1 and Figure 4 As shown, an external thread is provided on the adjusting screw 14, and an internal thread is provided on the inner wall of the outer shell 16 of the regulating valve. The adjusting screw 14 is threadedly connected with the outer shell 16. The adjusting screw 14 is driven to rotate by the clamping plate 12, so that the threads between the adjusting screw 14 and the outer shell 16 of the regulating valve are screwed together, and the position of the adjusting screw 14 in the regulating valve is adjusted to realize the adjustment of the regulating valve.

[0046] Furthermore, the card plate 12 may be rectangular or trapezoidal, as long as the card plate 12 can be embedded in two card slots 13 at the same time.

[0047] like Figure 5 As shown, in a feasible implementation, the internal combustion engine gas regulating valve wrench further includes: two fixing grooves 17 ; the fixing grooves 17 are symmetrically arranged on a side surface of the clamping plate 12 away from the operating rod 11 , and the fixing grooves 17 are recessed toward the direction close to the operating rod 11 .

[0048] In this technical solution, two fixing grooves 17 are symmetrically arranged on the first side surface of the card plate 12 facing away from the operating rod 11. When the card plate 12 is engaged with the card slot 13, part of the adjusting screw 14 can also be embedded in the two fixing grooves 17, so that the card plate 12 and the adjusting screw 14 are interlocked with each other, thereby increasing the contact depth and area of ​​the card plate 12 and the adjusting screw 14, and can improve the stability and reliability of the card plate 12 and the adjusting screw 14 to prevent the card plate 12 from detaching from the adjusting screw 14 during operation, thereby ensuring the continuity of the operation process and ensuring the adjustment efficiency of the adjusting screw 14.

[0049] Furthermore, a cavity 15 is provided on the top surface of the adjusting screw 14, so that the two slots 13 are located on the wall surface of the adjusting screw 14. By providing a fixing slot 17 on the card plate 12, the depth of the card plate 12 embedded in the cavity 15 can be increased, thereby improving the stability of the card plate 12 and the adjusting screw 14.

[0050] like Figure 6 As shown, in a feasible implementation manner, the operating rod 11 is a hollow cavity 15 with openings at both ends; the extension rod 18 can pass through the operating rod 11, and the extension rod 18 is movably connected to the operating rod 11.

[0051] In this technical solution, the operating rod 11 is a hollow cavity 15 with openings at both ends. By passing the extension rod 18 through the operating rod 11 to extend the length of the operating rod 11, not only can the power arm of the rotating adjusting screw 14 be increased, but it is also convenient for two people to operate at the same time. The operating rod 11 and the extension rod 18 can be carried separately to adapt to different types of regulating valves, which is convenient and practical.

[0052] In this technical solution, when the adjusting screw 14 is difficult to be turned, two operators operate the extension rod 18 at both ends of the extension rod 18 respectively to rotate the extension rod 18, thereby driving the operating rod 11 and the clamping plate 12 to rotate, thereby adjusting the adjusting screw 14, which is more labor-saving and can reduce manual labor intensity.

[0053] It is understandable that by adjusting the extension rod 18 to different positions of the operating rod 11, such as extending the extension rod 18 from one side of the operating rod 11, the power arm of the rotating adjustment screw 14 can be further increased, which is more labor-saving.

[0054] like Figure 7 As shown, in a feasible embodiment, the internal combustion engine gas regulating valve wrench also includes: a connecting portion 19; the connecting portion 19 is perpendicular to the operating rod 11, the first end of the connecting portion 19 is connected to the clamping plate 12, the operating rod 11 passes through the second end of the connecting portion 19, and the operating rod 11 is movably connected to the connecting portion 19.

[0055] In this technical solution, a connecting portion 19 is provided on the card plate 12, and the operating rod 11 passes through the connecting portion 19 and is slidably connected to the connecting portion 19. On the one hand, the setting of the connecting portion 19 can increase the distance between the operating rod 11 and the card plate 12. When the card plate 12 extends into a narrow space, the operator can rotate the operating rod 11 outside the narrow space, so that the wrench can adapt to different working conditions and improve the practicality of the wrench; on the other hand, by adjusting the relative position of the operating rod 11 and the connecting portion 19, such as extending the extension rod 18 from one side of the operating rod 11, the power arm of the rotating adjustment screw 14 can be increased, which is more labor-saving.

[0056] In a feasible implementation manner, a threaded hole is provided in the connection portion 19 , an external thread is provided on the outer wall of the operating rod 11 , and the operating rod 11 is threadedly connected to the connection portion 19 .

[0057] In this technical solution, the operating rod 11 is connected to the connecting part 19 by a thread, so that after the position of the operating rod 11 relative to the connecting part 19 is adjusted, the position of the operating rod 11 is locked and fixed, thereby improving the stability and reliability of the wrench when in use, reducing the difficulty of operation, and preventing the clamping plate 12 from escaping from the clamping slot 13 in a narrow space during operation, which helps to ensure the continuity and safety of the process of adjusting the adjusting screw 14.

[0058] In a feasible implementation, the internal combustion engine gas regulating valve wrench further includes: an insert piece 20 ; the insert piece 20 is arranged parallel to the clamping plate 12 , and the insert piece 20 is detachably arranged in the clamping slot 13 .

[0059] In this technical solution, when the width of the slot 13 is greater than the thickness of the card plate 12, the gap between the card plate 12 and the slot 13 can be adjusted by placing an insert 20 in the slot 13. On the one hand, the card plate 12 can be tightly fixed in the slot 13, thereby improving the stability of the cooperation between the card plate 12 and the slot 13; on the other hand, the force-bearing area of ​​the card plate 12 is increased, the uniformity of the force on the card plate 12 is improved, and the card plate 12 is prevented from bending and deforming, which helps to extend the service life of the wrench.

[0060] Furthermore, the inserting pieces 20 may be designed to have different thicknesses, so that the gap between the card plate 12 and the card slot 13 can be adjusted to a minimum through the cooperation of a plurality of inserting pieces 20 .

[0061] like Figure 8 As shown, in a feasible implementation, the internal combustion engine gas regulating valve wrench further includes: two limit plates 21 ; the limit plates 21 are connected to the operating rod 11 , and the two limit plates 21 are arranged in parallel on both sides of the clamping plate 12 .

[0062] In this technical solution, limiting plates 21 are provided on both sides of the card plate 12, and the limiting plates 21 are connected to the operating rod 11, so as to limit the card plate 12 on both sides through the limiting plates 21, so as to prevent the card plate 12 from tilting or bending after being subjected to force, increase the connection strength between the card plate 12 and the operating rod 11, and improve the rigidity of the card plate 12, so as to ensure that after the wrench is used many times, the card plate 12 can still be simultaneously and accurately embedded in the two slots 13, thereby ensuring the accuracy of the card plate 12 and the slot 13 being locked.

[0063] like Fig. 9 and Fig.10 As shown, in a feasible implementation manner, the internal combustion engine gas regulating valve wrench further includes: an adjusting piece 22; the adjusting piece 22 is detachably disposed between two limiting pieces 21, and the adjusting piece 22 is slidably connected to the limiting piece 21.

[0064] In this technical solution, the adjusting piece 22 is slidably connected to the two limiting pieces 21. The adjusting piece 22 is slid between the two limiting pieces 21 to extend the length of the clamping plate 12, so that the wrench can be used for adjusting screws 14 and regulating valves with larger sizes, thereby expanding the scope of application of the wrench.

[0065] In this technical solution, the adjusting piece 22 is detachably connected to the limiting piece 21; when the distance between the two card slots 13 is greater than the length of one side of the card plate 12 away from the operating rod 11, when the adjusting piece 22 is inserted between the two limiting pieces 21, the adjusting piece 22 plays a role in extending the card plate 12, and the limiting piece 21 plays a role in supporting and limiting the adjusting piece 22, thereby ensuring the reliability of the limiting piece 21 during use; when the distance between the two card slots 13 is less than or equal to the length of one side of the card plate 12 away from the operating rod 11, the adjusting piece 22 does not need to be installed, and the limiting piece 21 only plays a role in limiting and protecting the card.

[0066] It can be understood that the longer the length of the card plate 12, the greater the tendency of the card plate 12 to deform under force. Therefore, the length of the card plate 12 should not be too long, and it is only necessary to ensure that the size of the adjusting screw 14 is suitable for most regulating valves; when a large-sized regulating valve needs to be adjusted, the card plate 12 is extended by installing the adjusting piece 22, so that the wrench can be suitable for large-sized regulating valves.

[0067] like Fig.10 As shown, in a feasible embodiment, the internal combustion engine gas regulating valve wrench also includes: a slide groove 23 and a slider 24; the slide groove 23 is arranged on the side wall of the limit plate 21 close to the clamping plate 12 along the length direction of the operating rod 11; the slider 24 is arranged on the adjusting plate 22, and the slider 24 is slidably connected to the slide groove 23.

[0068] In this technical solution, the slide groove 23 is arranged on the side wall of the limiting plate 21 close to the card plate 12 along the length direction of the operating rod 11, and a slider 24 adapted to the slide groove 23 is arranged on the adjusting plate 22. The sliders 24 on both sides of the adjusting plate 22 are respectively slid into the ends of the slide grooves 23 of the two limiting plates 21 to install the adjusting plate 22 between the two limiting plates 21, so as to extend the card plate 12.

[0069] Furthermore, when the adjusting piece 22 is installed at one end of the card plate 12, the extended length of the card plate 12 is adjusted by adjusting the distance between the limiting piece 21 and the card plate 12; when the adjusting pieces 22 are installed at both ends of the card plate 12, the extended length of the card plate 12 is adjusted by adjusting the distance between the two limiting pieces 21.

[0070] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0071] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
