Description

Technical Field

[0001] The present disclosure relates to the technical field of positioning beads, and in particular to a positioning bead with a novel structure. Background Art

[0002] Positioning beads, also known as touch beads, spring top beads or ball plungers, are a load-bearing device consisting of a shell, a spring, a sphere or a cylinder.

[0003] Existing methods for installing locating beads involve drilling a hole in the device and then connecting the locating bead housing to the hole through an interference fit, or by using a clearance fit or gluing. They can also be used as inserts placed in the mold and secured during the injection molding of the plastic part. These connection methods are not suitable for thin plate structures, making existing locating beads impossible to install on thin plates, limiting their use cases. Utility Model Content

[0004] The present disclosure provides a novel structural positioning bead to solve one of the technical problems recognized by the inventor.

[0005] The present disclosure provides a new type of structural positioning bead, including: a shell, a spring embedded in the interior of the shell, an opening at one end of the shell, a sphere embedded in the opening of the shell, the upper part of the sphere extending to the outside of the opening, and a riveted step fixedly connected to one end of the shell close to the opening.

[0006] Preferably, the outer contour of the riveted step is a polygonal structure, and a through hole is provided in the middle of the riveted step to allow the sphere to pass through.

[0007] Preferably, the outer contour of the riveted step is a hexagonal structure.

[0008] Preferably, a connecting plate is fixedly connected to the top end of the shell, the top end of the connecting plate is fixedly connected to the riveted step, and an annular groove is formed between the shell, the connecting plate and the riveted step.

[0009] Preferably, the riveted step is integrally connected to the shell.

[0010] Preferably, a vent hole is provided at one end of the shell away from the sphere.

[0011] The beneficial effects of the present disclosure are mainly that: the utility model opens a hole in the thin plate, and after the shell passes through the hole, the rivet step is riveted to the thin plate to fix the positioning beads, thereby realizing installation on the thin plate. At the same time, it can also be installed in a traditional way through interference fit, clearance fit, gluing, etc., thereby expanding the use scenarios of the positioning beads.

[0021] The technical solutions of the present disclosure will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0022] Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present disclosure.

[0023] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this disclosure and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on the specific circumstances.

[0025] Example

[0026] like Figure 1-3 As shown, this embodiment provides a new type of structural positioning bead, including a shell 1, the shell 1 is a cylindrical structure, the interior of the shell 1 is hollow, and an opening is opened at the top, a spring 3 is embedded in the interior of the shell 1, and a sphere 2 is embedded in the opening of the shell 1, the bottom of the sphere 2 is set against the spring 3, the upper part of the sphere 2 extends to the outside of the opening, the diameter of the opening is smaller than the diameter of the sphere 2, so that the sphere 2 can be partially extended, but the whole cannot be separated from the shell 1, and a riveted step 4 is provided at one end of the shell 1 close to the sphere 2. When the positioning bead is installed on a thick plate, it is fixed by opening a hole in the thick plate and connecting the shell 1 and the opening of the thick plate through an interference fit. If the positioning bead needs to be installed on a thin plate, it is installed by opening a hole in the thin plate, the shell 1 passes through the opening of the thin plate, and the riveted step 4 is fitted with the surface of the thin plate, and then the riveted step 4 is riveted into the thin plate for installation.

[0027] Furthermore, the outer contour of the riveted step 4 is a polygonal structure, and a through-hole is provided in the middle of the riveted step 4 to allow the ball 2 to pass through. In this embodiment, the outer contour of the riveted step 4 is a hexagon. Once the riveted step 4 is riveted into the thin plate, the hexagonal structure prevents the housing 1 of the positioning bead from rotating, providing a more stable installation. It should be noted that in this embodiment, the outer contour of the riveted step 4 is a hexagon, but in practice, a polygonal structure such as a quadrilateral or octagon can be set, as long as the outer contour is not circular, which facilitates rotation after being embedded in the thin plate.

[0028] Specifically, the top of the housing 1 is integrally connected to a connecting plate 5. The connecting plate 5 is a circular tubular structure and is disposed around the opening at the top of the housing 1. The riveted step 4 is integrally mounted on the top of the connecting plate 5, forming an annular groove 6 between the housing 1, the connecting plate 5, and the riveted step 4. When the riveted step 4 is riveted into the thin plate, the thin plate is squeezed and embedded in the groove 6, thereby making the positioning bead more stable and difficult to fall off.

[0029] Furthermore, a vent hole is provided at one end of the shell 1 away from the sphere 2. The vent hole allows air to circulate inside the shell 1.

[0030] The working principle of this utility model is as follows: Figure 4 As shown, Figure 4 This is a schematic diagram of the installation of positioning beads on thick plates in this embodiment. When it needs to be installed on thick plates, it is the same as the traditional positioning bead installation method, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the installation of positioning beads in the prior art, which is achieved by opening a hole in the thick plate and then connecting the housing 1 and the opening of the thick plate through interference fit. Figure 5 As shown, Figure 5 This is a schematic diagram of the positioning beads installed on the thin plate in this embodiment. When it needs to be installed on the thin plate, a hole is opened in the thin plate, and the shell 1 passes through the hole in the thin plate. After the riveted step 4 and the surface of the thin plate are fitted, the riveted step 4 is riveted into the thin plate for installation. After the riveted step 4 is riveted into the thin plate, the thin plate is squeezed and embedded in the annular groove 6 formed between the shell 1, the connecting plate 5 and the riveted step 4, thereby improving the stability of the positioning bead installation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
