Description

Technical Field

[0001] The utility model relates to the technical field of press riveting nut studs, in particular to a multi-section adjustable press riveting nut stud. Background Art

[0002] Press riveting is a processing method of pressing a part into another thinner plate for fixation, which is relatively common in some machinery. The hole to be pressed on the plate should be slightly smaller than the part to be press riveted to improve the firmness of press riveting. According to its characteristics and usage requirements, press riveting studs can be subdivided into various types. First, from the structure, there are threaded press riveting studs and non-threaded press riveting studs. The threaded press riveting studs provide a complete internal thread for the screwing in of fasteners such as bolts, while the non-threaded press riveting studs are mostly used for providing spacing or support.

[0003] In the prior art, the length of the press riveting nut stud is fixed. When it works, it needs to be used together with the plate of the corresponding thickness. Therefore, when processing plates of different thicknesses with press riveting nut studs, it is necessary to prepare a relatively large number of types of press riveting studs for use. Therefore, in some cases, if the thickness of the plate to be connected changes, it is necessary to replace the corresponding press riveting nut stud. Furthermore, it is necessary to remove the originally fixed specification press riveting nut stud and reposition the new press riveting nut stud, which is likely to affect the work progress and thus the work efficiency. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a multi-section adjustable press riveting nut stud to facilitate solving the technical problems mentioned in the above background art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A multi-section adjustable press riveting nut stud includes a press riveting head and a nut stud. The nut stud is arranged at the bottom end of the press riveting head. The number of the nut studs is several and they are arranged in a linear array. A number of arc-shaped plates are fixedly connected to the bottom end of the press riveting head. The arc-shaped plates are arranged in a circular array. The arc-shaped plates pass through several of the nut studs and are inserted into the nut stud at the lowermost position. A number of the arc-shaped plates are all slidably connected with a number of the nut studs. An external thread is provided on the side of the arc-shaped plate away from the axis of the nut stud. An internally threaded ring is rotatably connected to the outer peripheral side of the nut stud. The internally threaded ring is threadedly connected with the corresponding arc-shaped plate through the external thread.

[0007] In a preferred example of the utility model, it can be further configured as follows: an embedding groove is provided at the top of the outer peripheral side of the press riveting head, and the top side wall of the embedding groove is inclined.

[0008] In a preferred embodiment, the present utility model can be further configured as follows: a number of serrations are fixedly connected to the outer peripheral side of the riveting head, and the several serrations are arranged in an annular array.

[0009] In a preferred embodiment, the present utility model can be further configured as follows: the heights of all the nut posts above the lowermost nut post are the same, and the height of the lowermost nut post is greater than the height of any of the nut posts above.

[0010] In a preferred embodiment, the present utility model can be further configured as follows: the spacing between every two adjacent nut posts among all the nut posts is the same, and the spacing between the uppermost nut post and the riveting head is the same as the spacing between two adjacent nut posts.

[0011] In a preferred embodiment, the present utility model can be further configured as follows: the outer side walls of each internal thread ring are respectively aligned with the outer side walls of the corresponding nut posts.

[0012] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0013] 1. For this multi-stage adjustable riveting nut post, during use, by rotating the corresponding internal thread ring, the internal thread ring drives the corresponding nut post to move, thereby adjusting the spacing between the lowermost nut post and the riveting head, achieving the effect of adjusting the length of the riveting nut post. In addition, the spacing between two adjacent nut posts is ensured to be equal, so that after the riveting nut post fixes the plate, each nut post can be adjusted to the corresponding position, ensuring uniform force on the nut post and the arc-shaped plate and improving the service life.

[0014] 2. For this multi-stage adjustable riveting nut post, the provided embedding groove is such that when the riveting head is pressed into the corresponding plate, the circumferential side of the prefabricated hole will be extruded into the embedding groove, thus ensuring that after the riveting head is embedded into the prefabricated hole of the plate, the part of the prefabricated hole that is extruded into the embedding groove can limit the riveting head, thereby ensuring the stability of the riveting head after being embedded into the prefabricated hole.

[0015] 3. For this multi-stage adjustable riveting nut post, the several serrations provided are such that after the riveting head is embedded into the prefabricated hole of the plate, the serrations will be embedded into the surface side of the plate. At the same time, after being embedded into the side wall of the plate, the part of the plate that is embedded will also be extruded, further improving the stability of the riveting head after being embedded into the prefabricated hole of the plate.

[0016] 4. In this multi - stage adjustable blind rivet nut column, among the several nut columns set, except for the nut column at the bottom, the heights of the remaining nut columns are the same, and the height of the nut column at the bottom is greater than the height of any other nut column, which is used to increase the moving distance of the nut column at the bottom, thereby increasing the adjustable range of this blind rivet nut column, expanding the application range of this blind rivet nut column, and improving its practicability.

[0017] 5. In this multi - stage adjustable blind rivet nut column, the distance between every two adjacent nut columns is the same as the distance between the riveting head and the corresponding nut column, so as to ensure that when the nut column is used, after the plate is fixed, the force is evenly distributed, improving the stability of the plate when the plate is fixed, and thus improving the practicability.

[0023] The following further details the present invention with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Refer to Figures 1 - 3, a multi - section adjustable riveting nut column disclosed by the utility model includes a riveting head 1 and a nut column 2. The nut column 2 is arranged at the bottom end of the riveting head 1. The number of the nut columns 2 is several and they are arranged in a linear array. A number of arc - shaped plates 3 are fixedly connected to the bottom end of the riveting head 1. The arc - shaped plates 3 are arranged in a circular array. The arc - shaped plates 3 pass through several nut columns 2 and are inserted into the nut column 2 at the bottommost. A number of arc - shaped plates 3 are all slidably connected to a number of nut columns 2. An external thread 4 is provided on the side of the arc - shaped plate 3 away from the axis of the nut column 2. An internal - thread ring 5 is rotatably connected to the outer peripheral side of the nut column 2. The internal - thread ring 5 is threadedly connected to the corresponding arc - shaped plate 3 through the external thread 4.

[0026] In this embodiment, when the riveting nut column needs to be adjusted, the bottommost internal - thread ring 5 can be rotated at this time. Since the internal - thread ring 5 is threadedly connected to all arc - shaped plates 3 through the corresponding external thread 4, when the bottommost internal - thread ring 5 rotates, it will cause the internal - thread ring 5 to move downward. And the arranged nut column 2 and arc - shaped plate 3 are slidably connected. Therefore, when the bottommost internal - thread ring 5 rotates, it will drive the bottommost nut column 2 to move downward. After the bottommost nut column 2 moves to a suitable position, then gradually rotate the remaining internal - thread rings 5 to make the remaining nut columns 2 move to the designated positions, so that the distance between every two adjacent nut columns 2 is the same. Thus, while adjusting the length of the riveting nut column, the distance between every two adjacent nuts is the same, ensuring uniform force on the nut column 2 during use, and further ensuring that it can be applicable to plates of different thicknesses. At the same time, after the riveting nut column is installed, the force is evenly distributed, thereby improving the stability.

[0027] It should be noted that a number of arc - shaped plates 3 are arranged in a circular array and their axes are collinear with the axis of the riveting head 1. And a number of internal - thread rings 5 are rotatably installed on the corresponding nut columns 2, so that the internal - thread rings 5 can cover all arc - shaped plates 3, and the internal - thread rings 5 are threadedly connected to all arc - shaped plates 3 through the external thread 4 to ensure that the internal - thread rings 5 can be stable on the arc - shaped plates 3 and avoid affecting the support for the corresponding nut columns 2.

[0028] In a further preferred embodiment of the utility model, as Figures 1 - 3 shown, an embedding groove 6 is provided at the top of the outer peripheral side of the riveting head 1, and the top side wall of the embedding groove 6 is inclined.

[0029] In this embodiment, the embedded groove 6 is provided. When the riveting head 1 is pressed into the corresponding plate, the circumferential side of the prefabricated hole will be extruded into the embedded groove 6, so as to ensure that after the riveting head 1 is embedded into the prefabricated hole of the plate, the part of the prefabricated hole that is extruded into the embedded groove 6 can limit the riveting head 1, thereby ensuring the stability of the riveting head 1 after it is embedded into the prefabricated hole.

[0030] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, a number of serrations 7 are fixedly connected to the outer peripheral side of the riveting head 1, and the several serrations 7 are arranged in a circular array.

[0031] In this embodiment, among the several serrations 7 provided, after the riveting head 1 is embedded into the prefabricated hole of the plate, at this time the serrations 7 will be embedded into the surface side of the plate. At the same time, after being embedded into the side wall of the plate, it will also extrude the part embedded in the plate, further improving the stability of the riveting head 1 after it is embedded into the prefabricated hole of the plate.

[0032] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, the heights of all the nut posts 2 above the lowermost nut post 2 are the same, and the height of the lowermost nut post 2 is greater than the height of any of the nut posts 2 above.

[0033] In this embodiment, among the several nut posts 2 provided, except for the lowermost nut post 2, the heights of the remaining nut posts 2 are the same, and the height of the lowermost nut post 2 is greater than the height of any of the remaining nut posts 2, which is used to increase the moving distance of the lowermost nut post 2, thereby increasing the adjustable range of the riveting nut post, expanding the application range of the riveting nut post, and improving the practicability.

[0034] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, the spacing between every two adjacent nut posts 2 among all the nut posts 2 is the same, and the spacing between the uppermost nut post 2 and the riveting head 1 is the same as the spacing between two adjacent nut posts 2.

[0035] In this embodiment, the spacing between every two adjacent nut posts 2 is the same as the spacing between the riveting head 1 and the corresponding nut post 2, so as to ensure that when the nut post 2 is used, after the plate is fixed, the force is evenly distributed, improving the stability of the plate when the plate is fixed, thereby improving the practicability.

[0036] In a further preferred embodiment of the present utility model, as Figures 1 - 3 shown, the outer side walls of each internal thread ring 5 are respectively aligned with the outer side walls of the corresponding nut posts 2.

[0037] In this embodiment, the inner-threaded ring 5 is aligned with the outer sidewall of the corresponding nut post 2. When the nut post 2 fixes the plate, it is avoided that the upper and lower sides or the outer peripheral side of the inner-threaded ring 5 presses the plate, so that the side of the prefabricated hole of the plate is easily stuck, which further affects the insertion of the rivet nut post and the fixation of the corresponding plate.

[0038] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
