Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a multi-stage spring nut installation angle adjustment structure. Background Technology

[0002] In electronic device assembly, such as fixing the internal circuit board of a laptop, due to the compact space, the installation angle of the nut needs to be flexibly adjusted to adapt to different wiring routes, ensuring that the wiring connection is stable and does not obstruct other components. In the automotive manufacturing field, many parts in the engine compartment need to use this structure, which can realize the reliable installation of parts in complex and narrow spaces and ensure the safe operation of the car.

[0003] In existing technologies, the position adjustment of some spring clip nuts depends on the size and performance of the spring clip itself. For example, the common rear-mounted spring clip nut has a fixed spring clip on the back, which can be installed in the assembly point in the profile groove. However, the spring clip is a fixed structure and can only be adapted to specific profile specifications, thus limiting its application range.

[0004] However, in actual use, when the installation angle of the multi-stage spring nut cannot be adjusted, it will seriously affect its assembly flexibility. In complex equipment installation scenarios, it is difficult to meet different installation angle requirements, resulting in poor adaptability. Moreover, once the installation angle is wrong, the cost of disassembly and reinstallation is high, which will also hinder the progress of the project. In order to address the above problems, a multi-stage spring nut installation angle adjustment structure is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-stage spring nut installation angle adjustment structure, which aims to improve the problem that some multi-stage springs in the prior art cannot adjust the installation angle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-stage spring-loaded nut installation angle adjustment structure includes an upper spring, characterized in that: a nut is fixedly connected to the outside of the upper spring, a lower spring is fixedly connected to the outside of the nut, a bolt is threadedly connected to the inside of the nut, an adjustment mechanism is fixedly connected to the outside of the lower spring, and an anti-loosening mechanism is fixedly connected to the top of the bolt.

[0008] The adjusting mechanism includes a follower ring, a sliding block is externally threaded to the bolt, a threaded groove is provided inside the sliding block, a sliding assembly is fixedly connected to the outside of the sliding block, and the follower ring is externally fixedly connected to the outside of the nut.

[0009] As a further description of the above technical solution:

[0010] The sliding assembly includes a slide groove, an mounting plate is fixedly connected to the outside of the slide groove, a sliding block is slidably connected to the inside of the slide groove, and the outside of the sliding block is slidably connected to the outside of the slide groove.

[0011] As a further description of the above technical solution:

[0012] The anti-loosening mechanism includes a fixing block, and multiple limiting blocks are fixedly connected to the outside of the fixing block. The fixing block is fixedly connected to the outside of the bolt.

[0013] As a further description of the above technical solution:

[0014] The bolt has multiple slotted holes on its outside, and a cotter pin is slidably connected to the outside of the slotted holes.

[0015] As a further description of the above technical solution:

[0016] The cotter pin is externally fixedly connected to a limiting shaft, and the cotter pin is externally slidably connected to the inside of the bolt.

[0017] As a further description of the above technical solution:

[0018] One end of the follower ring is fixedly connected to the outside of the nut, and the other end of the follower ring is slidably connected to the outside of the sliding block;

[0019] As a further description of the above technical solution:

[0020] A spring washer is fixedly connected to the outside of the fixing block, and the outside of the spring washer is in contact with the side of the nut that is close to it.

[0021] As a further description of the above technical solution:

[0022] The external thread of the bolt is connected to the inside of the nut, and the thread on the opposite side of the bolt is connected to the inside of the sliding block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by rotating the bolt, the nut drives the follower ring to rotate, which in turn causes the bolt to drive the sliding block to move, and then the sliding block moves inside the mounting plate. This allows for flexible adaptation to different installation scenarios, avoids installation problems caused by fixed angles, reduces the cost of custom parts, and reduces wear on components caused by angle deviations.

[0025] 2. In this utility model, the external mounting and fixing block of the bolt allows the open nozzle to slide in the opening groove, thereby limiting the opening nozzle with the limiting block. At the same time, a spring washer is fixedly connected to the bottom of the fixing block. Under different installation angles, the spring can produce stable elastic deformation and tightly bite the mounting surface. When the equipment vibrates during operation, it can flexibly buffer the vibration with its own structure, thereby effectively preventing the bolt from loosening. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a multi-stage spring nut installation angle adjustment structure, including an upper spring 1. The upper spring 1 has a regular arc shape and good elasticity and toughness. It can undergo elastic deformation when subjected to a certain external force and quickly return to its original shape. A nut 2 is fixedly connected to the outside of the upper spring 1, and a lower spring 3 is fixedly connected to the outside of the nut 2. The shape of the lower spring 3 is very similar to that of the upper spring 1, and it also has excellent elastic performance, thereby ensuring the uniformity of the entire structure in terms of mechanical performance and durability. A bolt 5 is connected to the internal thread of the nut 2. A specially designed anti-loosening mechanism is connected to the top of the bolt 5. This mechanism is composed of multiple precision parts and adopts a special locking principle, which can effectively prevent the bolt 5 from loosening due to continuous vibration, impact and other complex external forces during equipment operation, thereby ensuring the stability and reliability of the entire installation structure. An adjustment mechanism is fixedly connected to the outside of the lower spring 3, and an anti-loosening mechanism is fixedly connected to the top of the bolt 5.

[0034] The adjusting mechanism includes a follower ring 4, a sliding block 6 externally threaded to the bolt 5, a threaded groove 7 internally provided in the sliding block 6, and a sliding assembly externally fixedly connected to the sliding block 6. The sliding block 6 is designed as a cuboid shape, and its interior is precisely machined to form a threaded groove 7 that precisely matches the external thread of the bolt 5. When the bolt 5 rotates, the sliding block 6 will move along the axial direction of the bolt 5 in a stable and uniform linear motion under the driving action of the thread. The follower ring 4 is externally fixedly connected to the outside of the nut 2. The sliding assembly includes a slide groove 9, the surface of which is polished to reduce sliding friction resistance. A mounting plate 8 is externally fixedly connected to the slide groove 9, and the sliding block 6 is slidably connected inside the slide groove 9. The sliding block 6 is externally slidably connected to the outside of the slide groove 9.

[0035] Reference Figures 2 to 4 The anti-loosening mechanism includes a fixing block 10, which is externally fixedly connected to multiple limiting blocks 11. The fixing block 10 is externally fixedly connected to the bolt 5. The fixing block 10 is firmly fixedly connected to the outer side wall of the bolt 5 by a tight fit. The two are tightly integrated, as if they are fused together, to ensure that no relative displacement occurs during equipment operation. Multiple slotted holes 12 are opened on the outside of the bolt 5. The outside of the slotted holes 12 is slidably connected to the cotter pin 13. The cotter pin 13 is slidably connected to the outside of the slotted holes 12. The cotter pin 13 is slender U-shaped and has a certain degree of elasticity. The two ends of the cotter pin 13 are inserted into the slotted holes 12 and can slide flexibly in the slotted holes 12. The cotter pin 13 is externally fixedly connected to a limiting shaft 14. The presence of the limiting shaft 14 further restricts the movement trajectory of the cotter pin 13 and prevents it from sliding excessively and falling out of the slotted holes 12.

[0036] The cotter pin 13 is externally slidably connected to the inside of the bolt 5. One end of the follower ring 4 is fixedly connected to the outside of the nut 2. The outside of the spring washer 15 is in contact with the side of the nut 2. The elastic force generated by the spring washer can effectively prevent the bolt 5 from loosening due to vibration or other reasons during equipment operation, and always maintain the tightening force on the bolt 5. The other end of the follower ring 4 is slidably connected to the outside of the sliding block 6. The outside of the fixed block 10 is fixedly connected to the spring washer 15. The spring washer 15 will be compressed and produce elastic deformation. The outside of the spring washer 15 is in contact with the side of the nut 2. The external thread of the bolt 5 is connected to the inside of the nut 2, and the thread on the side of the bolt 5 that is far away is connected to the inside of the sliding block 6.

[0037] Working principle: By adjusting the installation angle, the upper spring 1 and lower spring 3, with their regular arc-shaped structure and good elasticity, allow the bolt 5 to move up and down along the axial direction of the nut 2 when it rotates. The internal thread groove 7 is precisely matched with the external thread of the bolt 5, so that the rotation of the bolt 5 drives the sliding block 6 to make a stable and uniform linear displacement along the axial direction of the bolt 5 under the drive of the thread. Then, one end of the follower ring 4 is fixed to the outside of the nut 2, and the other end is slidably connected to the outside of the sliding block 6. When the sliding block 6 moves, the follower ring 4 moves with the sliding block 6, ensuring the coordination of the adjustment process.

[0038] A slender, U-shaped, and elastic cotter pin 13 is inserted into the multiple slots 12 on the outside of the bolt 5, allowing both ends of the cotter pin 13 to slide flexibly within the slots 12. The limiting shaft 14 connected to the cotter pin 13 restricts its sliding range and prevents it from coming off the slots 12. A spring washer 15 is fixedly connected to the outside of the fixing block 10, which causes the bolt 5 to undergo elastic deformation under compression during the tightening process. It then comes into close contact with the side of the nut 2, continuously providing elastic force and preventing the bolt 5 from loosening due to vibrations or other factors during equipment operation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
