[0002] At present, the matching connection method of nuts and screws is widely used in mechanical structures. When assembling the nut and the screw, in order to prevent the threaded connection between the nut and the screw from loosening, a gasket is usually installed between the nut and the screw. During installation, the gasket is first put on the screw by hand or with a tool, then the nut is put on the screw, and finally the nut is tightened to complete the connection or fixation between the two structures. However, in some places with narrow installation space, it is very inconvenient to insert the gasket and nut, making it difficult to install the gasket and nut, reducing the installation efficiency of the nut and gasket. In addition, some existing gasket and nut installation tools have a relatively complex structure and a relatively cumbersome processing process, which greatly increases the production cost.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0031] In order to solve the problems of low efficiency when installing nuts in a narrow space and the complex structure of the nut installation tool, according to an embodiment of the present application, a nut introduction and installation tool is provided. The following will be described in detail with reference to the accompanying drawings.

[0032] See also Figures 1 to 8 As shown, according to an embodiment of the present invention, an introduction and installation tool for a nut is provided. The introduction and installation tool for a nut includes an elongated body 10 .

[0033] An introduction channel 11 is provided through the length direction of the slender body 10 . The introduction channel 11 is used to introduce and transport the nut 20 . An output end 111 of the introduction channel 11 has a channel section 112 that is adapted to the shape of the nut 20 .

[0034] In the present application, the nut introduction and installation tool can guide the nut 20 into the structure compatible with the nut 20, thereby completing the installation of the nut 20. When using the nut introduction and installation tool of the present application, first, the operator places the nut 20 into the introduction channel 11. Under the action of gravity, the nut 20 can slide along the length direction of the slender body 10 in the introduction channel 11 to the output end 111 of the introduction channel 11. Since the output end 111 of the introduction channel 11 has a channel section 112 that is compatible with the shape of the nut 20, when the nut 20 slides to the channel section 112, it can stay in the channel section 112. Then, the end of the slender body 10 provided with the output end 111 of the introduction channel 11 is inserted into the structure compatible with the nut 20. The slender body 10 is then rotated to tighten the nut 20 onto the structure compatible with the nut 20. Finally, the nut introduction and installation tool is removed from the nut 20 and the structure compatible with the nut 20 to complete the installation of the nut 20.

[0035] Compared with the existing installation tools for installing nuts, the import installation tool for nuts of the present application adopts a simple structural design to complete the installation of the nut 20, and the import installation tool for nuts of the present application is simple to operate, which is convenient for improving the efficiency of installing the nut 20 in a narrow space.

[0036] Further, see Figure 1 and Figure 2 As shown, the cross-sectional area of ​​the introduction channel 11 gradually decreases along the length direction of the slender body 10, and the cross-sectional area of ​​the input end 113 of the introduction channel 11 is larger than the cross-sectional area of ​​the nut 20, and the cross-sectional area of ​​the output end 111 of the introduction channel 11 is equal to the cross-sectional area of ​​the nut 20.

[0037] Specifically, the present application sets the nut introduction and installation tool as a slender body 10 so that the slender body 10 can be inserted into some narrow spaces to complete the installation of the nut 20. The length direction of the slender body 10 is Figure 1In the direction indicated by y, the cross-sectional area of ​​the introduction channel 11 refers to the area of ​​the introduction channel 11 cut along a direction perpendicular to the length of the slender body 10, and the cross-sectional area of ​​the nut 20 refers to the area of ​​the nut 20 cut along the radial direction of the nut 20. In the present application, the cross-sectional area of ​​the input end 113 of the introduction channel 11 is set to be larger than the cross-sectional area of ​​the nut 20. More specifically, the diameter of the circumscribed circle of the figure cutting the input end 113 of the introduction channel 11 along a direction perpendicular to the length of the slender body 10 is larger than the diameter of the circumscribed circle of the nut 20. With this configuration, an operator can easily insert the nut 20 into the introduction channel 11 when using the nut introduction and installation tool of the present application. Furthermore, the cross-sectional area of ​​the output end 111 of the introduction channel 11 is set to be equal to the cross-sectional area of ​​the nut 20. That is, the diameter of the circumscribed circle of the figure cutting the output end 111 of the introduction channel 11 along the direction perpendicular to the length of the slender body 10 is equal to the diameter of the circumscribed circle of the nut 20. This configuration can prevent the nut 20 from easily falling off the output end 111 of the introduction channel 11 when the nut 20 slides from the input end 113 to the output end 111 during use of the nut introduction and installation tool of the present application. In addition, the cross-sectional area of ​​the input end 113 of the introduction channel 11 should not be set much larger than the cross-sectional area of ​​the nut 20. If the cross-sectional area of ​​the input end 113 of the introduction channel 11 is much larger than the cross-sectional area of ​​the nut 20, the operator will be uncertain about the posture of the nut 20 at the input end 113 of the introduction channel 11 when inserting the nut 20 into the input end 113, which may easily prevent the nut 20 from smoothly reaching the output end 111 of the introduction channel 11.

[0038] Further, see Figures 1 to 3 As shown, the cross-sectional shape of the introduction channel 11 includes a regular hexagon or a circle. Specifically, the cross-sectional shape of the introduction channel 11 of the present application can also be a square or other structure. When manufacturing the introduction and installation tool for the nut of the present application, the cross-sectional shape of the introduction channel 11 can be reasonably adjusted according to the shape of the nut 20 to meet the requirements of installing the nut 20 and the gasket 40.

[0039] Further, see Figures 1 to 3 As shown, an input groove 12 is further provided on the slender body 10 ; the bottom of the input groove 12 is communicated with the input end 113 of the introduction channel 11 , and the cross-sectional area of ​​the input groove 12 is larger than the cross-sectional area of ​​the input end 113 of the introduction channel 11 .

[0040] Specifically, the input slot 12 has a certain depth along the length direction of the elongated body 10, and the input slot 12 is arranged to facilitate the operator to put the nut 20 into the input end 113 of the guide channel 11 when using the nut guide installation tool of the application. When using the nut guide installation tool of the application, the operator can first put the nut 20 into the input slot 12. Since the bottom of the input slot 12 is in communication with the input end 113 of the guide channel 11, and the cross-sectional shape of the input end 113 of the guide channel 11 is similar to the cross-sectional shape of the nut 20, the operator can move the nut 20 in the input slot 12, and the nut 20 can fall into the guide channel 11 from the input end 113 of the guide channel 11, and finally be transported to the channel section 112 of the guide channel 11.

[0041] Further, referring to Figures 2 to 8 As shown, the elongated body 10 is further provided with a gasket slot 13, the gasket slot 13 is located at the output end 111 of the guide channel 11, and the bottom of the gasket slot 13 is in communication with the channel section 112, and the gasket slot 13 is at least used for placing the gasket 40.

[0042] Exemplarily, the cross-sectional shape of the gasket slot 13 can be a regular or irregular shape such as a circle, a square, and a regular hexagon. The embodiment shows the case that the cross-sectional shape of the gasket slot 13 is a circle. The arrangement of the gasket slot 13 facilitates the operator to guide the gasket 40 onto the screw rod 30, thereby completing the subsequent anti-loosening work of the nut 20. When using the nut guide installation tool of the application, the operator first puts the gasket 40 into the gasket slot 13, and then inserts the end of the nut guide installation tool with the gasket 40 into the connecting hole 61 of the second predetermined structure 60, thereby guiding the gasket 40 onto the screw rod 30.

[0043] Further, referring to Figures 2 to 8 As shown, the center line of the gasket slot 13 coincides with the center line of the guide channel 11, and the cross-sectional area of the gasket slot 13 is greater than the cross-sectional area of the channel section 112, and the outer diameter of the gasket 40 is equal to the diameter of the gasket slot 13.

[0044] Specifically, to ensure good coaxiality between the gasket 40 and the nut 20, the present application sets the center line of the gasket groove 13 to coincide with the center line of the introduction channel 11. When the nut introduction and installation tool of the present application is actually used, the operator places the nut 20 into the introduction channel 11 from the input end 113 of the introduction channel 11. The nut 20 is then transported through the introduction channel 11 to the output end 111 of the introduction channel 11 and stays in the channel section 112 of the introduction channel 11. The gasket 40 is then placed in the gasket groove 13. At this time, the center of the gasket 40 coincides with the center of the threaded hole of the nut 20. Therefore, when the operator uses the nut introduction and installation tool of the present application to install the nut 20 and the gasket 40, the nut 20 and the gasket 40 can be quickly introduced onto the screw 30 to complete the subsequent connection and fixation of the first predetermined structure 50 and the second predetermined structure 60.

[0045] Further, see Figures 2 to 8 As shown, the slender body 10 includes a first disc portion 14, a slender column 15 and a second disc portion 16, the inlet channel 11 is arranged through the slender column 15, the first disc portion 14 is arranged at the first end of the slender column 15, the input groove 12 is arranged at the first disc portion 14, and the second disc portion 16 is arranged at the second end of the slender column 15 opposite to the first end. The second disc portion 16 is provided with a gasket groove 13, and the outer diameter of the second disc portion 16 is smaller than the outer diameter of the first disc portion 14.

[0046] Specifically, the centerlines of the first disc portion 14, the slender column 15, and the second disc portion 16 all overlap, and the input slot 12 overlaps with the first disc portion 14, the introduction channel 11 overlaps with the centerline of the slender column 15, and the second disc portion 16 overlaps with the centerline of the gasket slot 13. This arrangement ensures that the centerlines of the input slot 12, the introduction channel 11, and the gasket slot 13 overlap. This arrangement ensures that when the nut 20 and the gasket 40 are placed on the nut introduction and installation tool of the present application, the centerlines of the nut 20 and the gasket 40 are located on the same straight line. When the operator inserts the nut introduction and installation tool with the nut 20 and gasket 40 installed into the connection hole 61 of the second predetermined structure 60, the nut 20 and the gasket 40 can be smoothly inserted onto the screw rod 30. If the structure of the nut guide installation tool of the present application cannot ensure that the center lines of the nut 20 and the washer 40 are on the same straight line when the nut 20 and the washer 40 are placed on the nut guide installation tool, the nut 20 or the washer 40 may easily tilt when the operator puts the nut 20 and the washer 40 on the screw 30, resulting in unreliable connection and fixation between the first predetermined structure 50 and the second predetermined structure 60. In addition, if Figure 4As shown, the provision of the first disc portion 14 also has a significant advantage. That is, when the nut guide installation tool is inserted into the connection hole 61 of the second predetermined structure 60, the first disc portion 14 can prevent the entire structure of the nut guide installation tool from falling into the connection hole 61 and being inconvenient to remove. At the same time, the provision of the slender column 15 allows the nut guide installation tool of the present application to be inserted into a narrow space for installing the nut 20 and the washer 40, which greatly improves the efficiency of installing the nut 20 and the washer 40 in a narrow space.

[0047] Further, see Figures 1 to 3 As shown, the outer periphery of the slender column 15 is provided with a reinforcing rib 17, which extends from the first disc portion 14 to the second disc portion 16, and the two ends of the reinforcing rib 17 are respectively connected to the first disc portion 14 and the second disc portion 16. The provision of the reinforcing rib 17 not only improves the overall structural strength of the nut introduction and installation tool, but also improves the torsional strength of the nut introduction and installation tool. As a result, when the nut introduction and installation tool of the present application is used to tighten the nut 20 and the washer 40 onto the screw rod 30, the nut introduction and installation tool is not easily broken due to the torsional shear stress, further improving the service life of the nut introduction and installation tool.

[0048] Further, see Figures 1 to 3 As shown, the height of the reinforcing rib 17 protruding from the slender column 15 gradually decreases from the first disc portion 14 to the second disc portion 16. Specifically, configuring the reinforcing rib as a gradual structure has several significant advantages: First, the gradual structure can optimize the stress distribution of the nut insertion and installation tool, avoiding structural failure caused by localized stress concentration. Second, it can reduce the weight of the nut insertion and installation tool. Third, it can reduce manufacturing costs. The use of a gradual structure can save material and, to a certain extent, reduce the manufacturing cost of the nut insertion and installation tool.

[0049] Further, see Figures 1 to 6 As shown, a concave-convex portion 18 is provided on the outer peripheral surface of one end of the slender body 10 close to the input end 113 of the introduction channel 11 .

[0050] Specifically, the concave-convex part 18 is arranged on the circumferential surface of the first disc part 14 and is composed of a plurality of convex edges arranged on the circumferential surface of the first disc part 14 and extending along the length direction of the elongated body 10. The arrangement of the concave-convex part 18 can increase the friction of the circumferential surface of the first disc part 14. When the introducing and mounting tool for nuts of the present application is used, the operator first inserts the introducing and mounting tool for nuts, in which the nut 20 and the gasket 40 are placed, into the connecting hole 61 of the second predetermined structure 60, and then holds the first disc part 14 with hands and rotates it in the clockwise direction, so that the nut 20 and the gasket 40 can be tightened on the screw rod 30, and then the first predetermined structure 50 and the second predetermined structure 60 are connected and fixed together.

[0051] It can be known from the above statements that the introducing and mounting tool for nuts of the present application can solve the problems of low efficiency and complex structure of the nut mounting tool when the nut is mounted. When the introducing and mounting tool for nuts of the present application is used, first, the operator places the nut 20 into the input slot 12, and then pushes the nut 20 into the input end 113 of the introducing channel 11, and then the nut 20 at the input end 113 is conveyed to the output end 111 of the introducing channel 11 and stays at the channel section 112 under the action of gravity, and then the gasket 40 is placed into the gasket slot 13. Then the screw rod 30 is slid into the sliding groove 51 on the first predetermined structure 50 extending along the length direction of the first predetermined structure 50 (the direction indicated by x in the figure), and the second predetermined structure 60 is sleeved on the screw rod 30 through the connecting hole 61. Finally, the end of the introducing and mounting tool for nuts, in which the gasket 40 is placed, is inserted into the connecting hole 61, and the introducing and mounting tool for nuts is rotated in the clockwise direction, so that the gasket 40 and the nut 20 can be fixed on the screw rod 30, and then the introducing and mounting tool for nuts is pulled out of the connecting hole 61, and the connection and fixation between the first predetermined structure 50 and the second predetermined structure 60 are completed. Figure 4

[0052] It can be known from the above statements that the introducing and mounting tool for nuts of the present application can solve the problems of low efficiency and complex structure of the nut mounting tool when the nut is mounted. When the introducing and mounting tool for nuts of the present application is used, first, the operator places the nut 20 into the input slot 12, and then pushes the nut 20 into the input end 113 of the introducing channel 11, and then the nut 20 at the input end 113 is conveyed to the output end 111 of the introducing channel 11 and stays at the channel section 112 under the action of gravity, and then the gasket 40 is placed into the gasket slot 13. Then the screw rod 30 is slid into the sliding groove 51 on the first predetermined structure 50 extending along the length direction of the first predetermined structure 50 (the direction indicated by x in the figure), and the second predetermined structure 60 is sleeved on the screw rod 30 through the connecting hole 61. Finally, the end of the introducing and mounting tool for nuts, in which the gasket 40 is placed, is inserted into the connecting hole 61, and the introducing and mounting tool for nuts is rotated in the clockwise direction, so that the gasket 40 and the nut 20 can be fixed on the screw rod 30, and then the introducing and mounting tool for nuts is pulled out of the connecting hole 61, and the connection and fixation between the first predetermined structure 50 and the second predetermined structure 60 are completed.
