[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] As a first aspect of this specific embodiment, a combined nut 1 is proposed, such as... Figures 1 to 4 As shown, the device includes a main body, a connecting strip 14, a linkage part, a first side ring 17, and a second side ring 18. The main body includes an elastic element 13, a first nut 11, and a second nut 12. The first nut 11 and the second nut 12 are coaxially arranged 22. A first helix 15 is provided on the outer circumferential surface of both the first nut 11 and the second nut 12. The elastic element 13 is disposed between the first nut 11 and the second nut 12. At least one end of the connecting strip 14 is provided with a one-way buckle. The surface of the one-way buckle facing the other end of the connecting strip 14 is a holding part 1412, and the end face of the one-way buckle facing the connecting strip 14 is a slope 1411 with an inner higher surface and an outer lower surface. The linkage part is provided on the connecting strip 14 and is used to connect with the driving component. The first side ring 17, the main body, and the second side ring 18 are sequentially disposed on the connecting strip 14. The first side ring 17 and / or the second side ring 18 are disposed on the connecting strip 14 via the inclined surface 1411, and the abutment portion 1412 prevents the first side ring 17 or the second side ring 18 from leaving the connecting strip 14.

[0040] In the application of the combined nut 1 to the power assembly 2, the power assembly 2 comprises a sleeve with a screw groove on the inner periphery matched with the first screw groove 15, the combined nut 1 is sleeved in the sleeve, and the linear motion of the combined nut 1 can drive the sleeve to rotate around the axis 22 of the sleeve. The elastic member 13 keeps a certain elastic spacing between the first nut 11 and the second nut 12, so that the first screw groove 15 on the outer periphery of the combined nut 1 is in abutment with the screw groove on the inner periphery of the sleeve, thereby reducing or even eliminating the transmission gap between the combined nut 1 and the sleeve, and improving the stability of the transmission of the two. Therefore, the connecting strip 14 needs to be connected with the first side ring 17 (the second side ring 18) to limit the movement range of the first nut 11 and the second nut 12.

[0041] In order to realize the connection of the connecting strip 14 and the first side ring 17 (the second side ring 18), the one-way buckle comprises a slope 1411 and an abutting portion 1412, and the shapes of the slope 1411 and the abutting portion 1412 are as shown in Figure 3 and Figure 4 At least one end of the connecting strip 14 is provided with the one-way buckle. After the connecting strip 14 reaches the preset position and is fixed by an external component, the slope 1411 portion of the one-way buckle allows the first nut 11, the second nut 12 and the first side ring 17 (the second side ring 18) to slide along the slope 1411 to the connecting strip 14, and the abutting portion 1412 allows the first nut 11, the second nut 12 and the first side ring 17 (the second side ring 18) to be unable to be separated from the connecting strip 14, so that the one-way buckle has the function of one-way entering and reverse preventing separation.

[0042] In the installation and use of the combined nut 1, the first side ring 17 and the second side ring 18 can both be arranged on the connecting strip 14 through the slope 1411. One of the first side ring 17 and the second side ring 18 can be arranged on the connecting strip 14 without the slope 1411, and the other one can be arranged on the connecting strip 14 through the slope 1411.

[0043] In the work of the combined nut 1, in order to make it move linearly, in some embodiments, the driving component for driving the combined nut 1 to move is a linear push rod, a linear guide rail or other components that can move linearly. In other embodiments, a straight guide 16 structure can be arranged in the combined nut 1, at this time, neither the external driving component needs to be a linear motion component nor the robustness of the motion of the combined nut 1 can be further improved, so the driving component can be a lead screw 23 structure or other components that can provide linear and rotary motion. Specifically, the straight guide 16 can be arranged on the inner periphery of the first nut 11, or the straight guide 16 can be arranged on the inner periphery of the second nut 12, or as shown in Figure 1 and Figure 2 The inner periphery of the second nut 12 is also provided with a straight guide 16, so that the overall transmission of the combined nut 1 is more stable and reliable.

[0044] In some embodiments, the straight guide 16 is arranged on the inner circumferential surface of the first side ring 17, or the straight guide 16 is arranged on the inner circumferential surface of the second side ring 18, or the straight guide 16 is arranged on the inner circumferential surface of the first side ring 17 and the second side ring 18. The above arrangement can further improve the stability of the overall structure. In Figure 1 and Figure 5 In the embodiment shown, the straight guide 16 is in the form of a spline structure, and in addition to this, other shapes such as key connection can also be used to meet the working needs of the straight guide 16. Regardless of the guide structure and its deformation, it is within the scope of protection, and will not be repeated here.

[0045] In order to ensure that each part of the combined nut 1 is evenly stressed, the number of connecting strips 14 is at least two, and the plurality of connecting strips 14 are arranged in an array around the axis 22 of the first nut 11 on the inner surface of the first nut 11. In the embodiment shown in Figure 2 the number of connecting strips 14 is two, and in other embodiments, the structural stability can be further improved by increasing the number of connecting strips 14.

[0046] In some embodiments, as shown in Figure 3 the connecting strip 14 is sequentially divided into a leading end 141, a middle part 142 and a trailing end 143. The one-way buckle can be arranged at the leading end 141 of the connecting strip 14 as shown in Figure 4 , or it can be arranged at the trailing end 143 of the connecting strip 14, or it can be arranged at both the leading end 141 and the trailing end 143.

[0047] The combined nut 1 in this embodiment is usually located at the input part of the entire transmission system. In order to make the combined nut 1 move synchronously with the driving part, the combined nut 1 is also provided with a linkage part. In some embodiments as shown in Figure 3 the linkage part is arranged at the middle part 142 of the connecting strip 14, at this time the connecting strip 14 belongs to the embodiment of being directly fixedly connected to the driving part, and in other embodiments the linkage part can also be directly connected with the first side ring 17 (the second side ring 18), by driving the first side ring 17 (the second side ring 18) to move, the connecting strip 14 is equivalent to being indirectly fixed to the driving part. Moreover, the number of linkage parts is at least one, in Figure 2 and Figure 3 the embodiments shown, the shape of the linkage part can be concave. In other embodiments, the linkage part can also be convex, and can also achieve the technical effect of fixation. Since the connecting strip 14 penetrates the first nut 11 and the second nut 12, and is located at a relatively central position in the entire combined nut 1, the arrangement of the linkage part at the middle part 142 of the connecting strip 14 can improve the stability and carrying capacity during the movement of the transmission system.

[0048] In the embodiment shown inFigure 3 and Figure 4 In some embodiments shown, the first end 141 is provided with a one-way buckle, and the last end 143 is provided with a blocking part. Moreover, during operation, under the action of the elastic force of the elastic member 13, the first side ring 17 abuts against the supporting part 1412, and the second side ring 18 abuts against the blocking part.

[0049] The elastic element 13 can be as follows: Figure 2 The wave spring shown can also be a cylindrical spring or a rubber component or other part with elastic deformation, which will not be described in detail here.

The pitch of the second helix is ​​the same as that of the first helix 15. The transmission sleeve 21 is sleeved on the outside of the combined nut 1 through the cooperation of the first helix 15 and the second helix.

[0051] When the driving component drives the combined nut 1 to move along the shaft 22, the combined nut 1 and the transmission sleeve 21 rotate relative to each other around their own shaft 22.

[0052] like Figure 5 In the power assembly 2 shown, the output end of the driving component is a lead screw 23 and a lead screw nut 24. The power assembly 2 includes a tool for fixing the lead screw nut 24 to the combination nut 1. The power assembly 2 also includes a tool 25 for connecting the lead screw nut 24 and the connecting bar 14. The shaft 22 has a hole for setting the lead screw nut 24. The outer circumferential surface of the shaft 22 has a through groove 221. The through groove 221 communicates with the hole along the axial direction of the shaft 22. The tool 25 passes through the through groove 221 to fix the lead screw nut 24 and the combination nut 1.

[0053] exist Figure 5 In some embodiments shown, the paddle 25 has an inner protrusion and an outer protrusion, the inner protrusion being fixedly connected to the lead screw nut 24, and the outer protrusion being fixedly connected to the linkage part. In other embodiments, the paddle 25 is a rectangular piece, which can achieve a similar technical effect.

[0054] In the assembly and use of the combination nut 1, the connecting strip 14 first needs to be directly or indirectly fixed to the active component. Then, the main body (including the elastic element 13, the first nut 11, and the second nut 12) and the first side ring 17 (second side ring 18) are placed on the connecting strip 14 via a one-way snap fastener. After the main body and the first side ring 17 (second side ring 18) are placed on the connecting strip 14, the abutment part 1412 and the blocking part prevent the aforementioned components from detaching from the connecting strip 14. In such cases... Figure 2 andFigure 5 In the embodiment of the power assembly 2, the outer circumferential surface of the screw nut 24 is provided with a matching groove matched with the inner protrusion of the tab 25, the screw nut 24 is arranged in the hole of the shaft 22, the matching groove of the screw nut 24 corresponds to the through groove 221 of the outer circumferential surface of the shaft 22, the tab 25 is embedded in the matching groove of the screw nut 24 through the through groove 221 of the shaft 22, then the connecting strip 14 is fixedly connected with the outer protrusion of the tab 25 through the linkage part of the middle part 142, the first side ring 17, the first nut 11, the elastic member 13, the second nut 12 and the second side ring 18 are sequentially clamped into the connecting strip 14 from the one-way buckle, and the first side ring 17, the first nut 11, the elastic member 13, the second nut 12 and the second side ring 18 are prevented from being separated from the connecting strip 14 under the cooperation of the blocking part and the abutting part 1412.
