Description

Technical Field

[0001] This utility model relates to the field of integrated fastener technology, specifically to an integrated fastener device with self-tightening function. Background Technology

[0002] Fasteners are frequently used in the mechanical field. There are many different types of fasteners. When fixing plate-shaped items, it is usually necessary to use plate clamps and bolts and nuts to fix them.

[0003] When using existing clamps and bolts to fix multi-layer boards, uneven pressure can occur. When subjected to external forces, the clamps often loosen or break. Under impact, vibration, or heavy loads, the screws and nuts may loosen their threaded connections, causing the fasteners to fall off and disrupting the clamp fixation. To address this, we propose an integrated fastener device with a self-tightening function. Utility Model Content

[0004] The purpose of this invention is to provide an integrated fastener device with self-tightening function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated fastener device with self-tightening function, comprising a bolt, two upper retaining rings connected to the top outer side of the bolt, and a lower retaining ring provided below each of the two upper retaining rings. Multiple upper inclined blocks are connected to the side of the upper retaining rings near the lower retaining rings, and multiple lower inclined blocks are connected to the side of the lower retaining rings near the upper retaining rings. Multiple upper compression strips are connected to the side of the upper retaining rings away from the lower retaining rings, and multiple lower compression strips are connected to the side of the lower retaining rings away from the upper retaining rings. A nut is connected to the bottom outer side of the bolt, and a groove is formed inside the nut. A nut is provided below the nut and threaded onto the outer wall of the bolt. A protrusion is connected to the top center of the nut. The protrusion and the groove are correspondingly arranged. Multiple elastic elements are connected to the outside of the protrusion. Slots are connected around the inside of the groove, and the multiple slots and multiple elastic elements are arranged in a one-to-one correspondence.

[0006] As a further embodiment of this utility model: a fixed ring is connected to the middle of the bottom of the second nut, and a movable ring is connected to the inner side of the fixed ring.

[0007] As a further embodiment of this utility model: internal threads are provided on the inner sidewalls of both the protrusion and the nut.

[0008] As a further embodiment of this utility model: the height of the elastic element is set to one-quarter of the height of the slot, and both sides of the elastic element are arc-shaped.

[0009] As a further embodiment of this utility model, the plurality of the upper inclined blocks and lower inclined blocks are arranged in a one-to-one correspondence.

[0010] As a further embodiment of this utility model, the inclination directions of the plurality of upper extrusion strips and lower extrusion strips are arranged in opposite directions.

[0011] As a further embodiment of this utility model: multiple pressing plates are provided on the outer side of the bolt, and the multiple pressing plates are all located between the upper retaining ring and the lower retaining ring. The bottom end of the bolt passes through the internal center of the pressing plate, the upper retaining ring, the lower retaining ring, nut one, and nut two in sequence.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model, through the cooperative arrangement of protrusions and grooves, prevents the bolt and nut from falling off under impact, vibration, or heavy load when they are connected to the bolt by the height difference between them. In addition, the elastic element and the slot cooperate so that when the nut and nut are engaged, multiple elastic elements simultaneously enter the corresponding slots, increasing the friction between the nut and nut and thus increasing the difficulty of the nut and nut and the bolt falling off.

[0014] 2. This utility model uses the cooperation of the upper and lower inclined blocks to make the upper and lower retaining rings tightly connected. Furthermore, the corresponding upper and lower extrusion strips on the upper and lower retaining rings respectively engage the top of the pressing plate and the bolt, strengthening the connection and further preventing the bolt from falling off.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 -Appendix Figure 4 This utility model discloses an integrated fastener device with self-tightening function, comprising a bolt 1. Two upper retaining rings 3 are connected to the top outer side of the bolt 1. A lower retaining ring 4 is provided below each of the two upper retaining rings 3. Multiple upper inclined blocks 5 are connected to the side of the upper retaining rings 3 near the lower retaining rings 4. Multiple lower inclined blocks 6 are connected to the side of the lower retaining rings 4 near the upper retaining rings 3. Multiple upper compression strips 7 are connected to the side of the upper retaining rings 3 away from the lower retaining rings 4. Multiple lower compression strips 8 are connected to the side of the lower retaining rings 4 away from the upper retaining rings 3. A nut 1 9 is connected to the bottom outer side of the bolt 1. A groove 10 is formed inside the nut 1 9. A nut 2 12 is provided below the nut 1 9. Nut 12 is threaded onto the outer wall of bolt 1. A protrusion 11 is connected to the top center of nut 12. The protrusion 11 and the groove 10 are correspondingly arranged. Multiple elastic elements 16 are connected to the outer side of the protrusion 11. The groove 10 is connected to the inner perimeter of the groove 10. Multiple grooves 17 and multiple elastic elements 16 are correspondingly arranged. Internal threads 15 are provided on the inner sidewalls of the protrusion 11 and nut 9. Multiple pressing plates 2 are provided on the outer side of bolt 1. Multiple pressing plates 2 are located between upper retaining ring 3 and lower retaining ring 4. The bottom end of bolt 1 passes through the internal center of pressing plate 2, upper retaining ring 3, lower retaining ring 4, nut 9 and nut 12 in sequence.

[0024] In Embodiment 1, the plurality of upper inclined blocks 5 and lower inclined blocks 6 are arranged in a one-to-one correspondence, and the inclination directions of the plurality of upper extrusion strips 7 and lower extrusion strips 8 are arranged in opposite directions;

[0025] Specifically, the upper inclined block 5 and the lower inclined block 6 are designed to work together to make the upper retaining ring 3 and the lower retaining ring 4 tightly connected. Furthermore, the upper extrusion strip 7 and the lower extrusion strip 8 on the upper retaining ring 3 and the lower retaining ring 4 respectively engage the top of the pressing plate 2 and the bolt 1, thereby strengthening the connection.

[0026] In the second embodiment, a fixing ring 13 is connected to the middle of the bottom of the second nut 12, and a movable ring 14 is connected to the inner side of the fixing ring 13. The height of the elastic element 16 is set to one-quarter of the height of the slot 17, and both sides of the elastic element 16 are arc-shaped.

[0027] Specifically, through the cooperation of the elastic element 16 and the slot 17, when the nut 19 engages with the nut 212, multiple elastic elements 16 simultaneously enter the corresponding slots 17, increasing the friction between the nut 19 and the nut 212, thereby increasing the difficulty of the nut 19, the nut 212 and the bolt 1 falling off. Furthermore, by setting the movable ring 14 at the bottom end of the bolt 1, after passing through the movable ring 14, when rotating in the opposite direction, the movable ring 14 will be stuck in the thread groove on the bolt 1, increasing the friction.

[0028] Working principle:

[0029] When fixing the pressing plate 2, the bolt 1 passes through the multi-layer pressing plate 2. Then, through the cooperation of the protrusion 11 and the groove 10, the height difference between the first nut 9 and the second nut 12 when connected to the bolt 1 prevents the bolt 1 and the nut from falling off under impact, vibration, or heavy load. The bolt 1 also cooperates with the elastic element 16 and the retaining groove 17, so that when the first nut 9 engages with the second nut 12, multiple elastic elements 16 simultaneously enter the corresponding retaining grooves 17, increasing the friction between the first nut 9 and the second nut 12, thereby increasing the friction between the first nut 9 and the second nut 12. The difficulty of detaching bolt 12 and bolt 1 is reduced. The movable ring 14 is set at the bottom of bolt 1. After passing through the movable ring 14, when rotating in the opposite direction, the movable ring 14 will be stuck into the thread groove on bolt 1, increasing the friction. At the same time, the upper inclined block 5 and the lower inclined block 6 are set to make the upper retaining ring 3 and the lower retaining ring 4 tightly connected. Furthermore, the upper extrusion strip 7 and the lower extrusion strip 8 on the upper retaining ring 3 and the lower retaining ring 4 respectively bite the top of the pressing plate 2 and bolt 1, strengthening the connection and further preventing the bolt 1 from falling off. At this point, the entire process is completed.
