Description

Technical Field

[0001] This utility model relates to the field of stud snap-fit ​​technology, and in particular to a universal structure for multi-specification standard studs. Background Technology

[0002] Currently, most automobiles are designed with studs, which are mainly used to fix and connect various parts of the vehicle body to ensure structural strength and safety. Corresponding to the studs, the vehicle body is also equipped with snap-fit ​​structures for fixing the studs.

[0003] Related technology can be found in Chinese Patent No. CN213361354U, which discloses a novel detachable stud clamp structure for automobiles. The structure includes a stud snap-fit ​​structure with a first clamp area and a second clamp area on both sides. A first clamp limiting beam is located within the first clamp area, with first connecting ribs fixedly connected to both ends of the first clamp limiting beam. The first connecting ribs are fixedly connected to the inner wall of the first clamp area. A second connecting rib is located at the upper end of the first clamp limiting beam, and multiple first locking angles are located below the first clamp limiting beam. A second clamp limiting beam is located within the second clamp area, with locking teeth connected to the middle of the second clamp limiting beam. Second locking angles are located on the lower edges of both sides of the second clamp area, and the locking teeth are fixedly connected to a pull rod. A through groove is provided on the stud snap-fit ​​structure, allowing the pull rod to move within the through groove. A disassembly seat is connected above the pull rod.

[0004] Regarding the aforementioned technologies, when the device is used in conjunction with studs, it can only snap onto studs of the corresponding size. Studs come in various sizes, and when fixing different types of studs, it is necessary to change the corresponding snap-fit ​​structure. This results in a limited range of applications, wasting time and costs. Therefore, there is an urgent need for a snap-fit ​​structure that can be applied to different studs. Utility Model Content

[0005] To accommodate studs of different sizes, this application provides a universal structure for multi-specification standard studs.

[0006] This application provides a universal structure for multi-specification standard studs, employing the following technical solution: A universal structure for multi-specification standard studs includes a retaining ring. Several branch blocks are uniformly fixed along the circumferential direction on the inner wall of the retaining ring. The ends of all branch blocks away from the inner wall of the retaining ring are close to the axial direction. The branch blocks are fixedly connected with threads for threaded engagement with the studs. The threads extend towards the axial direction of the retaining ring to engage studs of different diameters. An arc-shaped opening coaxial with the retaining ring is opened on the side of the thread near the axial direction of the retaining ring. The arc-shaped opening is adapted to the largest stud diameter corresponding to the retaining ring.

[0007] By adopting the above technical solution, the snap ring supports the threaded thread through the branch block. When the largest diameter stud passes through the middle of the arc-shaped opening, the outer wall of the stud fits against the inner wall of the arc-shaped opening. When the smaller diameter stud passes through the arc-shaped opening, there is a certain gap between the stud and the inner wall of the arc-shaped opening. When assembling studs of different diameters, the threaded thread always engages with the stud thread. The branch block supports and guides the stud through the threaded thread, thereby enabling the snap ring to support and limit the stud. At the same time, it can adapt to studs of different diameters, which is beneficial to improving the applicability and stability of the snap ring.

[0008] Optionally, the branch block is located at one end of the snap ring along the axial direction and is inclined to the other end along the axis of the snap ring, and the end face of the branch block near the connection with the snap ring is an inclined surface.

[0009] By adopting the above technical solution, when the stud passes through the arc-shaped opening, the branch block avoids and guides the stud by using the inclined surface, reducing the probability that the stud will cause the screw threads to move and deform the outer edge of the locking ring, which is beneficial to improving the stability of the device.

[0010] Optionally, the end face of the thread away from the branch block is set as a plane, and the arc-shaped opening is located between two planes on the same thread.

[0011] By adopting the above technical solution, the stud continuously rubs against the threaded teeth during rotation. The flat surface helps to strengthen the structural strength of the threaded teeth, reduces the probability of the threaded teeth breaking and generating burrs due to friction during rotation, and extends the service life of the device.

[0012] Optionally, a protrusion is fixed on the side of the branch block away from the inner wall of the snap ring, the protrusion extending away from the branch block, and the protrusion is located at the connection between the thread and the branch block.

[0013] By adopting the above technical solution, the branch block supports the protrusion, and the protrusion increases the height of the branch block, which helps to strengthen the structural strength of the branch block. When the stud rotates, it reduces the probability of the branch block shaking due to friction and improves the stability of the device.

[0014] Optionally, the inner wall of the snap ring is fixed with a plurality of support portions along the circumferential direction, and the support portions and branch blocks are alternately arranged.

[0015] By adopting the above technical solution, the support part and the branch block work together to support the snap ring, reducing the probability of deformation of the outer edge of the snap ring, which is conducive to improving the structural strength of the snap ring and the stability of the device operation.

[0016] Optionally, the support portion has grooves at both ends along the axis of the snap ring.

[0017] By adopting the above technical solution, the groove helps to reduce the weight of the overall structure. At the same time, when the vehicle is damaged and the stud accidentally comes off the arc-shaped opening and approaches the inner wall of the snap ring, the groove provides a buffer space for the stud, which helps to improve the safety of the device.

[0018] Optionally, the support portion gradually decreases in size along its vertical cross-section towards the axis of the snap ring.

[0019] By adopting the above technical solution, the support part fixes and supports the snap ring, which helps to improve the structural strength. When the branch block shakes, the support part supports the branch block, which helps to improve the stability and safety of the device.

[0020] Optionally, the vertical cross-sectional area of ​​the thread gradually decreases towards the axis of the snap ring.

[0021] By adopting the above technical solution, the thread thickness is gradually varied, allowing the thread to be matched with studs of different pitches, which helps to improve the applicability of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The snap ring supports the threaded thread through the branch block. When the largest diameter stud passes through the middle of the arc-shaped opening, the outer wall of the stud fits against the inner wall of the arc-shaped opening. When the smaller diameter stud passes through the arc-shaped opening, there is a certain gap between the stud and the inner wall of the arc-shaped opening. When assembling studs of different diameters, the threaded thread always engages with the stud thread. The branch block supports and guides the stud through the threaded thread, thereby enabling the snap ring to support and limit the stud. At the same time, it can adapt to studs of different diameters, which helps to improve the applicability and stability of the snap ring. 2. When the stud passes through the arc-shaped opening, the branch block avoids and guides the stud by using the inclined surface, reducing the probability that the stud will cause the thread to move and deform the outer edge of the locking ring, which is beneficial to improving the stability of the device. 3. During the rotation of the stud, it rubs against the threaded teeth continuously. The flat surface helps to strengthen the structural strength of the threaded teeth, reduces the probability of the threaded teeth breaking and producing burrs due to friction during rotation, and extends the service life of the device.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] This application discloses a general structure for a multi-specification standard stud. Example

[0028] Reference Figure 1 A universal structure for multi-specification standard studs includes a snap ring 1. Multiple branch blocks 2 are arranged circumferentially on the inner wall of the snap ring 1. Threads 21 are fixedly connected to the side of the branch blocks 2 away from the inner wall of the snap ring 1. The threads 21 all extend in the direction of the axis of the snap ring 1. The snap ring 1 supports the threads 21 through the branch blocks.

[0029] Reference Figure 1 The thread 21 is used for threaded connection with the stud, and the thread 21 has an arc-shaped opening 211 on the side near the axis of the retaining ring 1. The arc-shaped opening 211 is coaxial with the retaining ring 1, and the diameter of the arc-shaped opening 211 corresponds to the largest diameter stud that the retaining ring 1 can fit. When the largest diameter stud passes through the arc-shaped opening 211 and is threadedly connected with the thread 21, the outer wall of the stud fits against the inner wall of the arc-shaped opening 211 during the rotation of the stud. When a smaller diameter stud passes between multiple branch blocks 2 and is threadedly connected with the thread 21, a certain gap is left between the outer wall of the stud and the inner wall of the arc-shaped opening 211. The branch blocks 2 support and guide the studs through the thread 21, thereby enabling the retaining ring 1 to support and limit studs of different diameters, ultimately allowing the retaining ring 1 to fit with different studs, which is beneficial to improving the applicability and operational stability of the device.

[0030] Reference Figure 1 The thread 21 has a flat surface 212 on the side away from the inner wall of the snap ring 1. The arc-shaped opening 211 is located between the two flat surfaces 212 on the same thread 21. During the rotation of the stud, it continuously rubs against the surface of the thread 21. The flat surface 212 helps to strengthen the structural strength of the thread 21 and reduces the probability of the thread 21 breaking and generating burrs due to continuous friction during rotation, which helps to extend the service life of the device.

[0031] Reference Figure 1 The vertical cross-sectional area of ​​the thread 21 gradually decreases from the inner wall of the snap ring 1 towards the axis of the snap ring 1. When studs with different pitches come into contact with the thread 21, the thread and the thread 21 come into contact at different positions along the axis, so that the branch block 2 can support studs with different pitches through the thread 21. This allows the snap ring 1 to support and limit studs with different pitches, which is beneficial to improving the applicability of the device.

[0032] Reference Figure 1A protrusion 23 is fixedly installed on the side of the branch block 2 away from the inner wall of the snap ring 1. The protrusion 23 is located at the connection between the thread 21 and the branch block 2, and is used to increase the thickness of the branch block 2. The protrusion 23 extends away from the connection between the branch block 2 and the thread 21. The snap ring 1 supports the protrusion 23 through the branch block 2 and strengthens the connection between the branch block 2 and the thread 21. This helps to strengthen the structural strength of the branch block 2 and reduces the probability of the branch block 2 shaking due to friction when the stud rotates, thereby improving the stability of the device.

[0033] Reference Figure 1 and Figure 2 The branch block 2 is inclined from the inner wall of the snap ring 1 towards the axis of the snap ring 1, so that the side of the branch block 2 closest to the axis of the snap ring 1 is a slope 24. The slope 24 is arc-shaped and the inclination direction of the slope 24 is the same as the screw screwing direction. When the screw screw is inserted into the snap ring 1 along the inclination direction of the slope 24, the slope 24 avoids and guides the screw screw, reducing the probability of the screw screw teeth 21 moving when the screw screw rotates, thus reducing the probability of deformation of the inner wall of the snap ring 1. This is beneficial to improving the stability of the device.

[0034] Reference Figure 1 and Figure 2 The snap ring 1 has multiple support parts 3 along its circumference. The cross-sectional area of ​​the support parts 3 gradually decreases from the inner wall of the snap ring 1 towards the axis of the snap ring 1. The widest part of the support part 3 supports and reinforces the snap ring 1, which helps to improve the structural strength of the device. The support parts 3 and the branch blocks 2 are arranged alternately, with gaps between them to provide deformation space for the branch blocks 2. When the branch blocks 2 tend to wobble, the support parts 3 protect the adjacent branch blocks 2. At the same time, all the support parts 3 cooperate to limit the wobble range of the stud within the snap ring 1, thereby improving the stability of the device during operation.

[0035] Reference Figure 1 and Figure 2 The support part 3 has grooves 31 at both ends along the axis of the snap ring 1, which helps to reduce the weight of the support part 3. The end of the support part 3 near the branch block 2 along its length is inclined at the same angle as the branch block 2, thus providing clearance space for the stud. The support part 3 has an arc-shaped surface 311 vertically at the end near the axis. When the stud is dislodged from the arc-shaped opening 211 and approaches the contact part under the action of external force, the support part 3 accommodates and limits the stud through the arc-shaped surface 311. The grooves 31 provide buffer space for the stud, which helps to improve the safety of the device.

[0036] The implementation principle of a universal structure for multi-specification standard studs in this application embodiment is as follows: The operator rotates studs of different sizes and inserts them into the arc-shaped opening 211 along the inclined direction of the slope 24. When the stud with the largest diameter passes through the arc-shaped opening 211, the outer wall of the stud fits against the inner wall of the arc-shaped opening 211, and the thread 21 is always located within the adjacent thread. When the stud with a smaller diameter passes through the arc-shaped opening 211, a certain gap is left between the outer wall of the stud and the inner wall of the arc-shaped opening 211. During this process, the thread 21 is always threadedly connected to the corresponding stud, thus fixing the stud. The branch block 2 supports and guides the stud through the thread 21, thereby enabling the snap-fit ​​ring 1 to support and fix the stud. Ultimately, the snap-fit ​​ring 1 can snap onto studs of different sizes. During vehicle assembly, for studs of different sizes in similar vehicle models, there is no need to frequently change the snap-fit ​​structure to adapt to them, which is beneficial to improving the applicability of the device.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
