Description

Technical Field

[0001] This invention relates to a push-button switch with a signal light, and more particularly, to a signal light head cooperative guiding self-centering connection structure. Background Technology

[0002] In push-button switches with traffic lights, common connection structures for the light head generally include linkage hinge connections, spindle body and retaining ring connections, and ball and hemispherical hole interference fit connections. Among these, the linkage hinge connection uses a riveting process, making it impossible to separate the light head from the base after riveting. This makes replacing the light head inconvenient when the light malfunctions, resulting in poor interchangeability and maintainability. The spindle body and retaining ring connection has a gap in the fit, leading to poor centering. When pressed, the friction between the light head and the inner wall of the base is high, resulting in poor tactile feedback and a risk of jamming. The ball and hemispherical hole interference fit connection is prone to loosening after repeated insertion and removal due to ball wear, resulting in low connection reliability.

[0003] The Chinese utility model patent CN212542233U, entitled "A self-resetting indicator light with push-button switch and tactile feedback," is provided for reference. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the lamp head component and the base component of existing traffic lights cannot be separated, and to provide a novel signal light lamp head cooperative guiding self-centering connection structure.

[0005] To achieve this objective, the technical solution of the present invention is as follows: a signal light head cooperative guiding self-centering connection structure, comprising, The lamp holder assembly includes a lamp holder bottom wall and a lamp holder spindle. A guide component has a first elastic claw and a second elastic claw shorter than the first elastic claw. The first elastic claw and the second elastic claw are respectively arranged on opposite sides of the lamp head spindle. The first elastic claw extends downward from the bottom surface of the lamp head bottom wall and has a first claw groove extending in a vertical direction and a first claw opening below the first claw groove. The second elastic claw extends downward from the bottom surface of the lamp head bottom wall. A base component is located below the lamp head component. The base component has a first base guide portion inside the first claw slide groove and a second base guide portion inside the second claw slide groove. The first base guide portion slides along the first claw slide groove, and the second base guide portion slides along the second claw slide groove.

[0006] As a preferred embodiment of a self-centering connection structure for coordinated guidance of traffic light heads, it also includes, The self-centering component includes a lock cylinder body, a ball bearing, and a limiting bushing. The lock cylinder body has an upward-opening internal space, and the lamp holder spindle extends downward into the internal space. The limiting bushing is fixed and surrounds the outer periphery of the lock cylinder body. The lock cylinder body has multiple lock cylinder ball holes arranged circumferentially, and each lock cylinder ball hole contains one ball bearing. The ball bearing is located between the inner circumferential surface of the limiting bushing and the outer circumferential surface of the lamp holder spindle.

[0007] Compared with the prior art, the beneficial effects of the present invention are at least as follows: (1) The design of the guide component forms a cooperative guide, the function is reliable and effective, and the risk of pressing jamming is effectively avoided. (2) By allowing the ball to rotate freely between the limiting bushing and the lamp head spindle, the lamp head spindle is always in the center position, realizing the self-centering function of the signal lamp head during the pressing process. The structure is ingenious and compact, and the pressing positioning is accurate. (3) The guide component and the self-centering component are independent of each other, and the lamp head component and the base component are detachable. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. It should be noted that these descriptions of embodiments are intended to aid in understanding the invention and do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] Please see Figures 1 to 7 The figure shows a signal light head cooperative guiding self-centering connection structure.

[0017] The signal light head cooperative guiding self-centering connection structure consists of a light head component, a guide component 2, a base component 3, and a self-centering component 4.

[0018] The lamp holder component 1 has a lamp holder bottom wall 11 and a lamp holder spindle 12. The lamp holder bottom wall 11 and the lamp holder spindle 12 are fixedly connected in a detachable manner.

[0019] The guide component 2 has a first elastic claw 21 and a second elastic claw 22 shorter than the first elastic claw 21. The first elastic claw 21 and the second elastic claw 22 are respectively arranged on opposite sides of the lamp head spindle 12. In this embodiment, the first elastic claw 21 is on the right side of the lamp head spindle 12, while the second elastic claw 22 is on the left side of the lamp head spindle 12.

[0020] The first elastic claw 21 extends downward from the bottom surface of the lamp head bottom wall 11. The first elastic claw 21 has a first claw groove extending in the vertical direction and a first claw opening below the first claw groove, i.e., the first elastic claw 21 has a downward-opening vise structure. The second elastic claw 22 extends downward from the bottom surface of the lamp head bottom wall 11. The second elastic claw 22 also has a downward-opening vise structure. The bottom edge of the second elastic claw 22 is higher than the bottom edge of the first elastic claw 21. The first elastic claw 21 is mainly used to ensure the fixing strength between the lamp head component 1 and the base component 3. The second elastic claw 22 is mainly used to cooperate with the first elastic claw 21 for guidance. The shorter length of the second elastic claw 22 reduces its spatial proportion in the overall mechanism while ensuring sufficient strength.

[0021] The base component 3 is located below the lamp head component 1. The base component 3 has a first base guide portion 31 inside the first claw groove and a second base guide portion 32 inside the second claw groove. The first base guide portion 31 slides along the first claw groove. The second base guide portion 32 slides along the second claw groove. That is, the relative sliding between the first elastic claw 21 and the first base guide portion 31, and the relative sliding between the second elastic claw 22 and the second base guide portion 32, guides the downward movement of the lamp head component. In this embodiment, both the first base guide portion 31 and the second base guide portion 32 are cylinders extending in the front-rear direction.

[0022] Please see again Figure 1 , Figure 2 and Figure 3The assembly process of the lamp head component 1 and the base component 3 is as follows: The first elastic claw 21 is aligned downwards with the first base guide portion 31, and the second elastic claw 22 is aligned downwards with the second base guide portion 32. The lamp head component is moved downwards, causing the guide portion 2 and the base component 3 to move towards each other. The first base guide portion 31 enters the first claw groove through the first claw opening, and simultaneously, the second base guide portion 32 enters the second claw groove through the second claw opening. Preferably, the width of the first base guide portion 31 is smaller than the width of the first claw opening, and the width of the second base guide portion 32 is smaller than the width of the second claw opening, making it difficult for the assembled lamp head component 1 and the base component 3 to detach.

[0023] The self-centering component 4 includes a lock cylinder body 41, a ball bearing 42, and a limiting bushing 43. The limiting bushing 43 is fixed and surrounds the outer periphery of the lock cylinder body 41. The limiting bushing 43 is internally divided into an upper section, a middle section, and a lower section. The inner diameter of the middle section is smaller than that of the upper section. The lock cylinder body 41 has an upward-opening internal space. The lamp holder spindle 12 extends downward into the internal space. The lock cylinder body 41 has multiple lock cylinder ball holes arranged circumferentially. Each lock cylinder ball hole accommodates one ball bearing 42. The ball bearing 42 is located between the inner circumferential surface of the limiting bushing 43 and the outer circumferential surface of the lamp holder spindle 12. During the upward or downward movement of the lamp head spindle 12, the ball bearing 42 is always restricted by the limiting bushing 43, so that the lamp head spindle 12 is always in a centered state, realizing the self-centering function of the lamp head component during the pressing process.

[0024] The pressing process of the lamp head component 1: When the lamp head component is pressed down, it causes the guide component 2 to move downward. The first elastic claw 21 slides relative to the first base guide portion 31, and the second elastic claw 22 slides relative to the second base guide portion 32, forming a cooperative guide. At the same time, the ball bearing 42 rotates freely between the limiting bushing 43 and the lamp head spindle 12, so that the lamp head spindle 12 remains in a centered position during the downward movement, realizing the self-centering function of the lamp head component during the pressing process.

[0025] The release process of the lamp head component is as follows: the lamp head component resets upwards, driving the guide component 2 upwards. The first elastic claw 21 slides relative to the first base guide portion 31, and the second elastic claw 22 slides relative to the second base guide portion 32, forming a cooperative guide. Simultaneously, the ball bearing 42 rotates freely between the limiting bushing 43 and the lamp head spindle 12, ensuring that the lamp head spindle 12 remains centered throughout its upward movement, thus achieving the self-centering function of the lamp head component during the pressing process.

[0026] It is easy to see that the lamp head component maintains cooperative guidance and self-centering during both the pressing and releasing processes, which greatly reduces the friction between the moving parts and the fixed parts and effectively avoids the risk of jamming of the lamp head component during the pressing and releasing processes.

[0027] The above description merely illustrates embodiments of the present invention and is quite specific and detailed; however, it should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
