Description

Technical Field

[0001] This invention specifically relates to the field of nut assembly technology, and more specifically to an anti-loosening adaptive clearance adjusting nut assembly and its combination device. Background Technology

[0002] Two parts with openings can be tightened together with bolts and nuts, but in some cases the two parts with openings are not tightly fitted together, but have a gap; in this case, using conventional bolts and nuts to tighten them will squeeze the space between the two parts, which may lead to deformation or even damage to the parts. Summary of the Invention

[0003] Therefore, the present invention proposes an anti-loosening adaptive clearance adjusting nut assembly and its combination device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anti-loosening adaptive clearance adjusting nut assembly, comprising an adjusting nut assembly, wherein the adjusting nut assembly includes an outer adjusting nut assembly sleeve and an inner adjusting nut assembly sleeve, wherein the outer sleeve thread on the inner wall of the outer adjusting nut assembly sleeve matches and engages with the inner sleeve thread on the outer wall of the inner adjusting nut assembly sleeve, so that the outer adjusting nut assembly sleeve and the inner adjusting nut assembly sleeve can be connected by threads, and the longitudinal length can be adjusted by rotating the two relative to each other;

[0005] A groove is cut along the cross-sectional direction of the inner sleeve thread on the inner sleeve of the adjusting nut assembly to form a "V" shaped inner sleeve thread groove.

[0006] Furthermore, as a preferred embodiment, the adjusting nut assembly also includes a convex self-locking structure, which is matched and disposed within the threaded groove of the inner sleeve. By rotating the outer sleeve of the nut assembly and the inner sleeve of the adjusting nut assembly relative to each other, the self-locking structure can slide from one groove to another in the threaded groove of the inner sleeve.

[0007] When the outer sleeve of the nut assembly and the inner sleeve of the adjusting nut assembly have finished rotating relative to each other, the fastening bolt begins to tighten with the fastening nut;

[0008] When the outer sleeve of the nut assembly and the inner sleeve of the adjusting nut assembly attempt to rotate in opposite directions, the self-locking structure can retract to the last passed "V"-shaped inner sleeve threaded groove and lock with the "V"-shaped inner sleeve threaded groove, and cannot retract further, thereby preventing the threads from loosening.

[0009] Furthermore, as a preferred embodiment, the self-locking structure is provided with a self-locking structure slope one and a self-locking structure slope two. The self-locking structure slope one and the self-locking structure slope two respectively cooperate with the gentle slope surface and the steep slope surface of the inner sleeve thread groove. By adjusting the slope of the gentle slope surface and the steep slope surface of the inner sleeve thread groove, the self-locking structure can slide over the inner sleeve thread groove when the outer sleeve of the nut assembly and the inner sleeve of the adjusting nut assembly rotate in the installation direction. After the outer sleeve of the nut assembly and the inner sleeve of the adjusting nut assembly rotate into place, the self-locking structure locks with the inner sleeve thread groove.

[0010] The self-locking structure on the component mounting base can also engage with the vertical groove on the outer surface of the outer component to prevent the threads of the outer component and the inner component from rotating in the loosening direction.

[0011] An assembly device with an anti-loosening adaptive clearance adjusting nut assembly includes an assembly fixing base, an adjusting nut assembly inner sleeve, an inner cylinder, and an adjusting nut assembly outer sleeve. The adjusting nut assembly inner sleeve and the inner cylinder are assembled as one unit, and the inner cylinder is installed inside the adjusting nut assembly inner sleeve. The outer outer surface of the inner cylinder is in contact with the inner wall of the inner sleeve. The inner cylinder's lug is engaged with the inner sleeve's end face groove 1. The inner cylinder's locking hook is engaged with the inner sleeve's end face groove 2. The inner cylinder's locking hook is a self-locking buckle structure, which is connected to the outer outer surface of the inner cylinder through a notch in the inner cylinder.

[0012] The outer sleeve of the adjusting nut assembly is placed in the first component fixing seat. The outer outer surface of the outer sleeve of the adjusting nut assembly fits against the inner wall of the first component fixing seat, and the inner rib of the component fixing seat engages with the vertical groove on the outer outer surface of the outer sleeve, so that the outer sleeve of the adjusting nut assembly can move axially in the first component fixing seat.

[0013] The inner sleeve of the adjusting nut assembly is connected to the outer sleeve of the adjusting nut assembly via the inner sleeve thread engaging with the outer sleeve thread on the outer sleeve of the adjusting nut assembly.

[0014] The inner cylinder locking hook is a cantilever structure, and the inner cylinder locking hook is provided with an inner cylinder locking hook guide slope and an inner cylinder locking hook snapping surface.

[0015] When the inner cylinder is inserted into the inner sleeve of the adjusting nut assembly, the locking hook guide slope of the inner cylinder retracts inward;

[0016] After the inner cylinder 1 and the inner sleeve of the adjusting nut assembly are installed in place, the guide slope of the locking hook of the inner cylinder 1 returns to its original state. At the same time, the locking hook engagement surface of the inner cylinder 1 contacts the end face of the groove 2 on the end face of the inner sleeve and completes the engagement, thereby completing the assembly of the inner sleeve of the adjusting nut assembly with the inner cylinder 1.

[0017] Furthermore, as a preferred embodiment, the outer sleeve of the adjusting nut assembly is placed in the first component fixing seat, the outer outer surface of the outer sleeve of the adjusting nut assembly is in contact with the inner wall of the first component fixing seat, and the inner rib of the component fixing seat engages with the vertical groove on the outer outer surface of the outer sleeve, so that the outer sleeve of the adjusting nut assembly can move along its axial direction in the first component fixing seat.

[0018] Furthermore, as a preferred embodiment, the outer sleeve of the adjusting nut assembly is provided with an outer sleeve flange, and the outer contour dimension of the outer sleeve flange is larger than the outer contour dimension of the outer outer surface of the outer sleeve.

[0019] Furthermore, as a preferred embodiment, the component fixing base is provided with a self-locking structure and a component fixing base claw. The component fixing base claw is provided with a component fixing base claw guide slope and a component fixing base claw engagement surface. The component fixing base claw guide slope is a sloping surface, which can guide the component fixing base claw when it is installed with the hole. The component fixing base claw engagement surface is relatively steep, which can play a role in locking and preventing loosening.

[0020] The component fixing base claw is composed of multiple claws arranged in combination. The engagement surfaces of the multiple claws on the component fixing base claw are set to different heights to accommodate different engagement heights.

[0021] A combination device with an anti-loosening adaptive clearance adjusting nut assembly includes an inner cylinder II, an adjusting nut assembly outer sleeve, a locking ring, an adjusting nut assembly inner sleeve, and an assembly fixing seat II. The adjusting nut assembly inner sleeve and the assembly fixing seat II are assembled as one unit. The assembly fixing seat II has an inner claw, which enters the adjusting nut assembly inner sleeve along the inner wall groove of the inner sleeve.

[0022] The locking ring is provided with a locking ring clip body, a locking ring clip, and a self-locking structure. The locking ring is assembled with the outer sleeve of the adjusting nut assembly. After the locking ring expands, it can first be fitted onto the protrusion at the end of the outer sleeve, and then fitted into the groove at the end of the outer sleeve while simultaneously shrinking back to its original shape. The protrusion at the end of the outer sleeve can prevent the locking ring from coming off the outer sleeve of the adjusting nut assembly. The locking ring clip prevents the locking ring and the outer sleeve of the adjusting nut assembly from rotating relative to each other. The self-locking structure enables the outer sleeve of the adjusting nut assembly and the inner sleeve of the adjusting nut assembly to self-lock when they attempt to rotate in the loosening direction.

[0023] A combination device with an anti-loosening adaptive clearance adjusting nut assembly includes an inner cylinder, an inner fitting of the adjusting nut assembly, a locking ring, an outer fitting of the adjusting nut assembly, and a component fixing seat. The locking ring, the outer fitting of the adjusting nut assembly, and the component fixing seat can be assembled into one unit. The inner surface of the component fixing seat ...

[0024] An assembly with an anti-loosening adaptive clearance adjusting nut assembly includes an inner cylinder II, an adjusting nut assembly outer sleeve, an adjusting nut assembly inner sleeve, and an assembly fixing seat II. The inner cylinder II's inner cylinder II latch matches and connects with the opening on the flange of the outer sleeve, so that the inner cylinder II and the adjusting nut assembly outer sleeve are assembled together.

[0025] The inner claw of the component fixing seat two engages with the groove step of the inner wall of the inner sleeve, and the bottom protrusion of the inner sleeve engages with the positioning hole on the component fixing seat, thereby assembling the component fixing seat two and the inner sleeve of the adjusting nut component together.

[0026] The assembly formed by the second component fixing seat and the inner sleeve of the adjusting nut assembly is connected to the assembly formed by the second inner cylinder and the outer sleeve of the adjusting nut assembly through the inner sleeve thread and the outer sleeve thread, and the outer outer surface of the outer sleeve fits against the inner wall of the second component fixing seat.

[0027] The present invention employs the above technology and has the following beneficial effects compared with the existing technology: The adjusting nut assembly in the device of the present invention can not only adjust the gap by rotating the threads on the inner and outer parts, but also provide support between the two fixed parts. Moreover, the innovative anti-loosening structure can prevent the threads from retracting and causing a decrease in the fastening effect or loosening. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example: Please refer to the appendix. Figure 1-18 The present invention provides a technical solution: an anti-loosening adaptive clearance adjusting nut assembly, which includes an adjusting nut assembly 100. The adjusting nut assembly 100 includes an adjusting nut assembly outer sleeve 600 and an adjusting nut assembly inner sleeve 700. The outer sleeve thread 602 on the inner wall of the adjusting nut assembly outer sleeve 600 matches and engages with the inner sleeve thread 702 on the outer wall of the adjusting nut assembly inner sleeve 700, so that the adjusting nut assembly outer sleeve 600 and the adjusting nut assembly inner sleeve 700 can be connected by threads, and the two can adjust the longitudinal length by rotating relative to each other, thereby achieving the purpose of adjusting the distance.

[0049] A slot is cut along the cross-sectional direction of the inner sleeve thread 702 on the inner sleeve of the adjusting nut assembly 700 to form a “V” shaped inner sleeve thread groove 701, or a slot is cut along the cross-sectional direction of the outer sleeve thread 602 to form a “V” shaped outer sleeve thread groove 601.

[0050] Specifically, depending on different environmental requirements, the inner fitting threaded groove 701 and the outer fitting threaded groove 601 can also be set as a "U" shaped groove or other groove shape. When set as a "V" shaped groove, it can be composed of the outer fitting threaded groove gentle slope surface 6011 and the outer fitting threaded groove steep slope surface 6012 or the inner fitting threaded groove gentle slope surface 7011 and the inner fitting threaded groove steep slope surface 7012.

[0051] In this embodiment, the adjusting nut assembly 100 also includes a convex self-locking structure 800. The self-locking structure 800 is matched and disposed in the inner sleeve threaded groove 701. Through the mutual rotation of the outer sleeve 600 of the nut assembly and the inner sleeve 700 of the adjusting nut assembly, the self-locking structure 800 can slide from one groove to another in the inner sleeve threaded groove 701.

[0052] Specifically, when the outer sleeve 600 of the nut assembly and the inner sleeve 700 of the adjusting nut assembly finish rotating relative to each other, the fastening bolt 400 begins to tighten with the fastening nut 500. When the outer sleeve 600 of the nut assembly and the inner sleeve 700 of the adjusting nut assembly attempt to rotate in the opposite direction, the self-locking structure 800 can retract to the last "V" groove it passed through and lock with the "V" groove, and cannot continue to retract, thereby preventing the threads from loosening.

[0053] It should be noted that the specific implementation involves setting two self-locking slopes, 801 and 802, on the self-locking structure 800. These slopes respectively cooperate with the outer fitting thread cutting gentle slope 6011 and the outer fitting thread cutting steep slope 6012, or the inner fitting thread cutting gentle slope 7011 and the inner fitting thread cutting steep slope 7012. The outer fitting thread cutting gentle slope 6011, the outer fitting thread cutting steep slope 6012, and the inner fitting thread cutting gentle slope 7011 are adjustable. The slope of the steep slope surface 7012 of the inner sleeve threaded groove allows the self-locking structure 800 to easily slide over the threaded groove 601 of the outer sleeve or the threaded groove 701 of the inner sleeve when the outer sleeve of the nut assembly 600 and the inner sleeve of the adjusting nut assembly 700 rotate in the installation direction. After the outer sleeve of the nut assembly 600 and the inner sleeve of the adjusting nut assembly 700 are rotated into place, the self-locking structure 800 can lock with the threaded groove 601 of the outer sleeve or the threaded groove 701 of the inner sleeve, thereby achieving the purpose of preventing loosening.

[0054] For example, such as Figure 1 and 2As shown, when the inner fitting 700 of the nut assembly rotates in the installation direction shown, due to the small slope of the self-locking structure slope 801 on the self-locking structure 800 and the gentle slope 7011 of the inner fitting thread groove, the self-locking structure slope 801 easily slides over the gentle slope 7011 of the inner fitting thread groove. However, when the inner fitting 700 of the nut assembly rotates in the opposite direction to the installation direction shown, the self-locking structure slope 802 on the self-locking structure 800 will come into contact with the steep slope 7012 of the inner fitting thread groove. Due to the small slope of the self-locking structure slope 802 and the steep slope 7012 of the inner fitting thread groove, the self-locking structure slope 802... The slopes of 7012 are all quite steep. The self-locking structure slope 802 is blocked by the steep slope of the inner sleeve threaded groove 7012 and cannot continue to slide. The self-locking structure 800 is a convex structure, and the outer sleeve threaded groove 601 or the inner sleeve threaded groove 701 is a concave structure. It should be emphasized that the present invention does not limit their specific shapes, but for the purpose of demonstration, the present invention uses the "A" type self-locking structure 800 and the "V" type outer sleeve threaded groove 601 or inner sleeve threaded groove 701 as examples. The shapes in the figure do not constitute a limitation on the scope of the present invention.

[0055] This invention lists several types of claws, including component fixing base claw one 1001, component fixing base two outer claw 1302, and component fixing base three outer claw 1402. The component fixing base two outer claw 1302 is a cantilever beam structure, with a component fixing base two outer claw guide slope 13021 and a component fixing base two inner claw engagement surface 13022 at its end. The component fixing base two outer claw guide slope 13021 can play the role of installation guidance, and the component fixing base two inner claw engagement surface 13022 can play the role of engagement.

[0056] The component fixing base claw 1001 is a combination of multiple claws arranged in parallel. The component fixing base claw 10011 on different claws can be set to different heights in order to adapt to different clamping heights.

[0057] The component mounting base has three outer claws 1402 with a "V" or "U" shaped structure. This structure makes the claws easier to deform and easier to install. The component mounting base forms a "V" shaped structure with the outer claw main body 14023 and the component mounting base three outer claw guide slope 14021.

[0058] A combination device with an anti-loosening adaptive clearance adjusting nut assembly, which is a type A adjusting nut assembly combination device, includes a component fixing base 1000, an adjusting nut assembly inner sleeve 700, an inner cylinder 900, and an adjusting nut assembly outer sleeve 600. The adjusting nut assembly inner sleeve 700 and the inner cylinder 900 are assembled as one unit, and the inner cylinder 900 is installed inside the adjusting nut assembly inner sleeve 700. The outer outer surface 904 of the inner cylinder 900 fits against the inner wall 705 of the inner sleeve. The inner lug 901 of the inner cylinder 900 is engaged with the end face groove 703 of the inner sleeve. The inner locking hook 902 of the inner cylinder 900 engages with the end face groove 704 of the inner sleeve. The inner locking hook 902 is set as a self-locking buckle structure, which is connected to the outer outer surface 904 of the inner cylinder through the inner cylinder notch 905.

[0059] Specifically, the inner cylinder hook 902 is provided with an inner cylinder hook guide slope 9021 and an inner cylinder hook engagement surface 9022. The inner cylinder hook 902 is a cantilever structure with elasticity. When the inner cylinder 900 is installed into the inner fitting 700 of the adjusting nut assembly, the inner cylinder hook guide slope 9021 retracts inward. After the inner cylinder 900 and the inner fitting 700 of the adjusting nut assembly are installed in place, the inner cylinder hook guide slope 9021 returns to its original shape. At the same time, the inner cylinder hook engagement surface 9022 contacts the end face of the inner fitting end face groove 704 to complete the engagement. At this time, the inner fitting 700 of the adjusting nut assembly and the inner cylinder 900 are assembled.

[0060] The outer sleeve 600 of the adjusting nut assembly is placed in the component fixing seat 1000. The outer outer surface 608 of the outer sleeve of the adjusting nut assembly 600 is in contact with the inner wall 1002 of the component fixing seat, and the inner rib 1003 of the component fixing seat is engaged with the vertical groove 610 on the outer outer surface of the outer sleeve, so that the outer sleeve 600 of the adjusting nut assembly can move along its axial direction in the component fixing seat 1000.

[0061] The inner fitting 700 of the adjusting nut assembly is connected to the outer fitting thread 602 on the outer fitting 600 of the adjusting nut assembly via the inner fitting thread 702.

[0062] In this embodiment, the outer sleeve 600 of the adjusting nut assembly is provided with an outer sleeve flange 603. The outer contour dimension of the outer sleeve flange 603 is larger than the outer contour dimension of the outer outer surface 608 of the outer sleeve. The larger area is beneficial to reduce the pressure when clamping the parts and avoid damaging the parts.

[0063] In this embodiment, the component fixing base 1000 is provided with a self-locking structure 800 and a component fixing base claw 1001. The component fixing base claw 1001 is provided with a component fixing base claw guide slope 10012 and a component fixing base claw engagement surface 10011. The component fixing base claw guide slope 10012 is a sloped surface, which can play a guiding role when the component fixing base claw 1001 is installed with the hole, while the component fixing base claw engagement surface 10011 is relatively steep, which can play a role in locking and preventing loosening.

[0064] Specifically, when it is necessary to fix the upper plate 200 and the lower plate 300, there is a gap between the upper plate 200 and the lower plate 300 that cannot be eliminated. In this case, the fixing adjusting nut assembly 100A is placed between the upper plate 200 and the lower plate 300. The bottom surface 1004 of the assembly fixing seat is attached to the upper surface 302 of the lower plate, and the component fixing seat claw 1001 is fixed to the through hole 301 on the lower plate. At this time, the adjusting nut assembly 100A is fixed to the lower plate 300. The fastening bolt 400 is then passed through the upper plate. The through hole 201 is screwed into the adjusting nut assembly 100A type assembly; due to the engagement relationship between the inner rib 1003 of the component fixing seat and the vertical groove 610 on the outer surface of the outer sleeve, the adjusting nut assembly outer sleeve 600 and the component fixing seat 1000 cannot rotate relative to each other, but the adjusting nut assembly outer sleeve 600 can move axially; since the external thread 401 of the fastening bolt and the inner wall 903 of the inner cylinder are interference fit, the external thread 401 of the fastening bolt will drive the adjusting nut assembly inner sleeve 700 to tighten through the inner wall 903 of the inner cylinder. Bolt 400 rotates together; since the outer sleeve 600 of the adjusting nut assembly cannot rotate, under the interaction of the outer sleeve thread 602 and the inner sleeve thread 702, the outer sleeve 600 of the adjusting nut assembly rotates in contact with the lower plate 300, while the inner sleeve 700 of the adjusting nut assembly continuously moves away from the lower plate 300 until the upper surface 6031 of the outer sleeve flange contacts the lower surface 203 of the upper plate; at this time, the inner sleeve 700 of the adjusting nut assembly also makes full contact with the bottom of the component fixing seat 1000; the inner wall 903 of the inner cylinder is made of a relatively soft material, further... Tightening the fastening bolt 400 compresses and deforms the inner wall 903 of the inner cylinder. The fastening bolt 400 continues to approach the through hole 301 on the lower plate. When the fastening bolt 400 passes through the through hole 301 on the lower plate, the external thread 401 of the fastening bolt engages with the internal thread 501 of the fastening nut, thereby achieving the fastening of the fastening bolt 400 and the fastening nut 500. After tightening, the upper end face 502 of the fastening nut is in contact with the lower surface 303 of the lower plate, and the flange face 402 of the fastening bolt is in contact with the upper surface 202 of the upper plate.

[0065] It should be noted that, as Figure 4 , 5As shown in Figure 6, the self-locking structure 800 on the component fixing seat 1000 cooperates with the vertical groove 610 on the outer peripheral surface of the outer component to prevent the outer component thread 602 and the inner component thread 702 from rotating in the loosening direction, thereby achieving the purpose of preventing loosening.

[0066] A type B assembly of the adjusting nut assembly 100, such as... Figure 7-11 As shown, the B-type assembly of the adjusting nut assembly 100 includes an inner cylinder 1100, an outer sleeve 600, a locking ring 1200, an inner sleeve 700, and a mounting base 1300. The inner sleeve 700 and the mounting base 1300 are assembled together. The mounting base 1300 has an inner claw 1301. The inner claw 1301 enters the inner sleeve 700 along the inner wall groove 706 of the inner sleeve. Since the inner claw 1301 is a cantilever structure, and the guide slope 13011 of the inner claw is a slope, the guide slope 13011 contacts the inner wall groove 706, forcing the inner claw 1301 to bend and deform until the inner claw engagement surface 13012 engages with the inner wall groove step 707 of the inner sleeve. Figure 9 As shown, at this time, the component fixing seat 2 1300 and the inner sleeve 700 of the adjusting nut component are fixed together and cannot move relative to each other along the axial direction, nor can they rotate relative to each other.

[0067] The inner cylinder 1100 and the outer sleeve 600 of the adjusting nut assembly can be fixed together. The outer wall 1105 of the inner cylinder 1105 is placed inside the outer sleeve 600 of the adjusting nut assembly. The inner cylinder 2 latch 1104 is engaged with the opening 6033 on the flange of the outer sleeve and pulls the inner cylinder 1100 and the outer sleeve 600 of the adjusting nut assembly together.

[0068] The locking ring 1200 is provided with a locking ring clip body 1202, a locking ring clip 1201 and a self-locking structure 800. The locking ring clip 1201 is a concave structure, which can be formed by the locking ring clip side 12011 and the locking ring clip bottom 12012. The locking ring 1200 can be assembled with the outer sleeve 600 of the adjusting nut assembly. The locking ring 1200 is elastic and can expand. After expansion, it can first be fitted onto the protrusion 605 at the end of the outer sleeve, and then further fitted into the groove 606 at the end of the outer sleeve, and at the same time shrink back to its original shape.

[0069] The two sides of the locking ring 1200 are blocked by the inner end face 6051 of the outer sleeve end protrusion and the inner end face 607 of the groove at the end of the outer sleeve, respectively, and cannot be dislodged. The locking ring clip 1201 falls into the slot 604 at the end of the outer sleeve. The side 12011 of the locking ring clip is blocked by the side of the slot 604 at the end of the outer sleeve and cannot rotate. The locking ring 1200 is provided with a self-locking structure 800. The self-locking structure 800 can cooperate with the threaded groove 701 of the inner sleeve to form a one-way locking structure, preventing the outer sleeve 600 of the adjusting nut assembly and the inner sleeve 700 of the adjusting nut assembly from loosening in the opposite direction of tightening.

[0070] The assembly of the inner sleeve 700 and the component fixing seat 1300 of the adjusting nut assembly, together with the locking ring 1200, the outer sleeve 600 and the inner cylinder 1100 of the adjusting nut assembly, are connected by the inner sleeve thread 702 and the outer sleeve thread 602 to form the adjusting nut assembly type 100B assembly. The outer wall 1105 of the inner cylinder is nested in the inner wall 705 of the inner sleeve.

[0071] When installing the fastening bolt 400 and the adjusting nut assembly type 100B, follow the instructions. Figure 10 Tighten the fastening bolt 400 in the indicated rotation direction. The interference fit between the external thread 401 of the fastening bolt and the inner wall 1103 of the inner cylinder causes the assembly consisting of the locking ring 1200, the outer sleeve 600 of the adjusting nut assembly, and the inner cylinder 1100 to rotate relative to the assembly consisting of the inner sleeve 700 of the adjusting nut assembly and the second mounting base 1300. During rotation, the assembly of the locking ring 1200, the outer sleeve 600 of the adjusting nut assembly, and the inner cylinder 1100 moves away from the adjusting nut assembly. The inner sleeve 700 and the component fixing seat 2 1300 move axially until the upper surface 1101 of the inner cylinder 2 contacts the lower surface 203 of the upper plate; at the same time, the lower bottom surface 1305 of the component fixing seat 2 contacts the upper surface 302 of the lower plate, and the outer claw 1302 of the component fixing seat 2 engages in the through hole 301 on the lower plate. At this time, the adjustment of the gap of the adjusting nut assembly 100B type combination is completed, and the fastening bolt 400 is further tightened with the fastening nut 500 to complete the fastening action.

[0072] A C-type assembly of the adjusting nut assembly 100, such as... Figure 12-15As shown, the adjusting nut assembly 100C type assembly includes an inner cylinder 900, an adjusting nut assembly inner sleeve 700, a locking ring 1200, an adjusting nut assembly outer sleeve 600, and an assembly fixing seat 1400. The locking ring 1200, the adjusting nut assembly outer sleeve 600, and the assembly fixing seat 1400 can be assembled into one unit. The inner surface 14011 of the assembly fixing seat mates with the outer peripheral surface 611 of the outer sleeve. The main body 1401 of the assembly fixing seat has a groove that mates with the end protrusion 609 of the outer sleeve. The stop surface 6091 on the end protrusion of the outer sleeve blocks the groove on the main body 1401 of the assembly fixing seat, preventing the assembly fixing seat 1400 from falling off the outer peripheral surface 611 of the outer sleeve. The locking ring 1200 is inserted into the end groove 606 of the outer sleeve and cannot be removed due to the restriction of the end protrusion 605 of the outer sleeve.

[0073] The inner cylinder 900 and the inner sleeve 700 of the adjusting nut assembly are assembled as one unit. The outer surface 904 of the inner cylinder is in contact with the inner surface of the inner sleeve 700 of the adjusting nut assembly, while the outer rib 906 of the inner cylinder is in contact with the inner wall groove 706 of the inner sleeve. The size of the outer rib 906 of the inner cylinder can be set to be slightly larger than the inner wall groove 706 of the inner sleeve to form an interference fit, which makes it difficult for the inner cylinder 900 to fall off in the inner sleeve 700 of the adjusting nut assembly. The assembly consisting of the inner cylinder 900 and the inner sleeve 700 of the adjusting nut assembly is connected to the assembly consisting of the locking ring 1200, the outer sleeve 600 of the adjusting nut assembly, and the component fixing seat 1400 through the outer sleeve thread 602 and the inner sleeve thread 702.

[0074] The adjusting nut assembly 100C type is fixed to the through hole 301 on the lower plate by the outer claw 1402 of the component fixing seat three. The fastening bolt 400, through the interference relationship with the inner wall 903 of the inner cylinder, drives the assembly composed of locking ring 1200, adjusting nut assembly outer sleeve 600 and component fixing seat three 1400 to rotate relative to the assembly composed of inner cylinder 900 and adjusting nut assembly inner sleeve 700, and moves axially. After the two ends of the adjusting nut assembly 100C type contact the lower surface 203 of the upper plate and the upper surface 302 of the lower plate respectively, the gap adjustment action of the adjusting nut assembly 100C type is completed, and the fastening bolt 400 and fastening nut 500 are tightened to complete the fastening action.

[0075] A D-type assembly of adjusting nut assembly 100 includes an inner cylinder 1100, an adjusting nut assembly outer sleeve 600, an adjusting nut assembly inner sleeve 700, and an assembly fixing seat 1300. The inner cylinder 1104 is fitted with the opening 6033 on the flange of the outer sleeve, so that the inner cylinder 1100 and the adjusting nut assembly outer sleeve 600 are assembled together.

[0076] The inner claw 1301 of the component fixing seat 2 engages with the groove step 707 of the inner wall of the inner sleeve, and the bottom protrusion 709 of the inner sleeve cooperates with the positioning hole 1306 on the component fixing seat, thereby assembling the component fixing seat 2 1300 and the inner sleeve 700 of the adjusting nut component together.

[0077] The assembly formed by the component fixing seat 2 1300 and the inner sleeve 700 of the adjusting nut assembly is connected to the assembly formed by the inner cylinder 2 1100 and the outer sleeve 600 of the adjusting nut assembly through the inner sleeve thread 702 and the outer sleeve thread 602. At the same time, the outer outer surface 1 608 of the outer sleeve is in contact with the inner wall 2 1307 of the component fixing seat.

[0078] The adjusting nut assembly 100D type is engaged with the through hole 301 on the lower plate via the outer claw 1302 of the component fixing seat 2, and the bottom of the component fixing seat 2 1300 is tightly pressed against the lower plate 300. At this time, the fastening bolt 400 is tightened and installed. The fastening bolt 400 is interference fit with the inner wall 1103 of the inner cylinder 2. When rotating, it drives the assembly formed by the inner cylinder 2 1100 and the adjusting nut assembly outer sleeve 600 to rotate together, so that it gradually moves away from the lower plate 300. When the upper surface 1101 of the inner cylinder 2 contacts the lower surface 203 of the upper plate, the gap adjustment action of the adjusting nut assembly 100D type is completed. Continue to tighten the fastening bolt 400 to complete the fastening action with the fastening nut 500. In order to prevent the adjusting nut assembly outer sleeve 600 from loosening relative to the adjusting nut assembly inner sleeve 700, a self-locking structure 800 can be set to cooperate with the vertical groove 610 on the outer surface of the outer sleeve to prevent loosening.

[0079] In practical implementation, the adjusting nut assembly 100 can be placed between two fixed plates, and the inner surfaces of the two plates are supported at both ends of the adjusting nut assembly 100, while the bolts pass through the internal through holes of the adjusting nut assembly 100 for fixation; for example Figure 5 As shown, the adjusting nut assembly 100 is first placed between the upper plate 200 and the lower plate 300. The fastening bolt 400 passes through the adjusting nut assembly 100 and is then tightened with the fastening nut 500. When the fastening bolt 400 is turned in the installation direction, the fastening bolt 400 first contacts the inner cylinder 900 or the inner cylinder 1100 on the adjusting nut assembly 100, and drives them to rotate together. At this time, the outer sleeve thread 602 and the inner sleeve thread 702 will separate and move along the axial direction of the fastening bolt 400 until the adjusting nut... After the two ends of component 100 contact the inner surfaces of the upper plate 200 and the lower plate 300 respectively, the friction between the fastening bolt 400 and the inner cylinder 900 or the inner cylinder 1100 can no longer drive the inner cylinder 900 or the inner cylinder 1100 to rotate together. At this time, the fastening bolt 400 continues to move toward the fastening nut 500 and is tightened with the fastening nut 500. The upper plate 200 and the lower plate 300 remain in the same position due to the support of the adjusting nut component 100. At this time, the installation process is completed.

[0080] It should be noted that during the above process, the adjusting nut assembly 100 will automatically adapt to the non-fixed gap between the upper plate 200 and the lower plate 300 within the working stroke range, thereby realizing the function of adaptive gap compensation and assisting bolt tightening.
