It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] See also Figures 1 to 4 Now, a shaft rotating tool provided by the utility model is described. A shaft rotating tool comprises a main rod body 100 and a lever arm 200. One end of the main rod body 100 is provided with a threaded connection end, the axial direction of the threaded connection end is perpendicular to the axial direction of the main rod body 100, and the threaded connection end is used to thread the central threaded hole of the pump shaft. The lever arm 200 is coaxially connected to the other end of the main rod body 100. A positioning block 140 is provided on the main rod body 100, and a positioning slot 141 is provided on the positioning block 140 for being clamped on the outside of the shaft key of the pump shaft.

[0027] Compared with the prior art, the shaft rotating tool provided by the utility model has a main rod body 100 connected to the central threaded hole of the pump shaft by means of a threaded connection end at one end thereof, and at the same time, a positioning slot 141 of a positioning block 140 on the main rod body 100 is clamped on the outside of the shaft key of the pump shaft. The power arm 200 is turned, and the pump shaft is driven to rotate through the connection relationship between the threaded connection end and the central threaded hole of the pump shaft and the limiting relationship between the positioning slot 141 and the shaft key of the pump shaft, and the pump shaft is gradually screwed into the central hole of the impeller to complete the installation. The shaft rotating tool provided by the utility model can quickly complete the assembly of the pump shaft, and the operation is very simple and will not cause damage to the pump shaft.

[0028] See also Figure 1 to Figure 2 A circular reinforcement end 110 is provided at one end of the main rod body 100, and the circular reinforcement end 110 is integrally formed. There is a transition section between the main rod body 100 and the circular reinforcement end 110, and the width of the transition section gradually increases from the main rod body 100 to the circular reinforcement end 110. The axial direction of the circular reinforcement end 110 is perpendicular to the axial direction of the main rod body 100, and the threaded connection end is coaxially connected to the circular reinforcement end 110.

[0029] Specifically, the threaded connection end is a fixing bolt 120, and the circular reinforcement end 110 is coaxially provided with a through hole. The fixing bolt 120 passes through the through hole from the outside and is threadedly connected to the central threaded hole of the pump shaft. The nut end of the fixing bolt 120 is located outside the through hole, and the fixing bolt 120 passes through the through hole. By rotating the fixing bolt 120, one end of the fixing bolt 120 passing through the through hole is gradually screwed into the central threaded hole of the pump shaft until the nut end of the fixing bolt 120 is pressed against the outer end surface of the circular reinforcement end 110.

[0030] Please also read Figure 3 The positioning block 140 is provided with a connecting rod, which penetrates and connects the main rod body 100. Positioning baffles 143 are respectively provided on both sides of the positioning block 140, and the gap between the two positioning baffles 143 constitutes a positioning slot 141. The shaft key width of the pump shaft is defined as B, and the spacing of the positioning slot 141 formed between the inner end faces of the two positioning baffles 143 is B+1mm, ensuring that the positioning slot 141 can be smoothly clamped on both sides of the shaft key of the pump shaft to form a positioning relationship, and at the same time there will be no large margin, reducing shaking.

[0031] In addition, anti-rotation baffles 144 are respectively provided on both sides of the positioning block 140 close to the main rod body 100. The two anti-rotation baffles 144 are clamped on both sides of the main rod body 100. The two anti-rotation baffles 144 form a limit, which can prevent the positioning block 140 from rotating itself and cause the positioning slot 141 to be unable to align with the shaft key of the pump shaft.

[0032] Specifically, the connecting rod is a connecting bolt 142, and the main rod body 100 is provided with an adjusting slot 130 along the axial direction. The connecting bolt 142 penetrates the adjusting slot 130 and is threadedly connected to the positioning block 140. The connecting bolt 142 can be moved along the length direction of the adjusting slot 130 to adjust the position of the positioning block 140. When using the shaft rotating tool provided by the utility model, the connecting bolt 142 is first moved along the adjusting slot 130 to a position away from the circular reinforcement end 110. After the fixed thread and the central threaded hole of the pump shaft are connected, the connecting bolt 142 is moved, and the connecting bolt 142 drives the positioning block 140 to move toward the direction close to the circular reinforcement end 110. At this time, the shaft key of the pump shaft is located directly below one end of the pump shaft. As the positioning block 140 continues to approach the circular reinforcement end 110, the positioning slot 141 is finally clamped outside the shaft key of the pump shaft.

[0033] Preferably, the lever arm 200 is coaxially welded to the other end of the main rod body 100 to ensure that the two have sufficient connection strength.

[0034] See also Figure 1 and Figure 2 An extension sleeve 300 is provided on the outside of the lever arm 200, and the extension sleeve 300 is threadedly connected to the lever arm 200. By rotating the extension sleeve 300, the extension sleeve 300 rotates and moves axially toward the end away from the main rod body 100, thereby lengthening the lever arm of the lever arm 200 as a whole and reducing the difficulty of operation for the operator.

[0035] Specifically, a threaded section 210 is provided at one end of the lever arm 200 away from the main rod body 100, the outer diameter of the threaded section 210 is larger than the outer diameter of the lever arm 200, and the extension sleeve 300 is threadedly connected with the threaded section 210. In order to avoid the problem of the extension sleeve 300 falling off due to excessive rotation of the extension sleeve 300, a necking section is provided inside the end of the extension sleeve 300 close to the main rod body 100, and the inner diameter of the necking section is smaller than the outer diameter of the threaded section 210. When installing the extension sleeve 300, the extension sleeve 300 is first inserted from the end of the lever arm 200 away from the threaded section 210 until the end of the lever arm 200 away from the threaded section 210 passes through the end of the extension sleeve 300, and then the end of the lever arm 200 that passes through is welded to the main rod body 100.

[0036] Preferably, a screw plug 310 is threadedly installed at one end of the extended sleeve 300 away from the main rod body 100, and the screw plug 310 can be sealed at the end of the extended sleeve 300 to prevent oil or dust from entering the extended sleeve 300 and affecting the internal threaded connection relationship of the extended sleeve 300, making the extended sleeve 300 difficult to rotate.

[0037] When using the spinner tool provided by the utility model, the specific operation process is as follows:

[0038] First, slightly loosen the connecting bolt 142, move the positioning block 140 to the end of the adjusting slot 130 away from the main rod body 100, and then use the fixing bolt 120 to penetrate the through hole of the circular reinforcement end 110 on the main rod body 100 from the outside, and fix the end of the fixing bolt 120 that has passed through it in the central threaded hole at the end of the pump shaft, and then slide the positioning block 140 along the adjusting slot 130 toward one end of the main rod body 100 until the positioning slot 141 of the positioning block 140 is opened outside the shaft key of the pump shaft, and tighten the connecting bolt 142 to fix the above positioning block 140. Through the rotation of the lever arm 200 and the extension sleeve 300, the pump shaft can be driven to rotate slowly, and the pump shaft can be slowly screwed into the center hole of the impeller, thereby completing the installation of the pump shaft.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
