Description

A smart terminal button with self-locking function Technical Field

[0001] This utility model relates to the field of power information acquisition terminal structure, and more specifically, it relates to a smart terminal button with a self-locking function. Background Technology

[0002] Power information acquisition terminals are crucial devices in power systems, primarily responsible for the real-time acquisition, storage, processing, and remote transmission of electrical energy. Currently, the usage of power information acquisition terminals in the market is gradually increasing. The buttons on commonly used power information acquisition terminals are mainly locked with rubber rings. However, silicone rings are prone to aging and cannot meet the harsh environments of high temperatures in southern summers, low temperatures in northern winters, and high salinity in coastal areas during daily use.

[0003] Although the installation of rubber ring locking buttons is automated during production, it is unavoidable that defective rubber rings or malfunctions of the machine's vibratory feeder may prevent the rubber rings from being properly installed into the locking grooves on the buttons. This improper installation of the locking rubber ring is difficult to detect during production, causing the rubber ring to fall off during transportation or customer use, resulting in button malfunction. Furthermore, the rubber rings are prone to breakage or deformation during installation, which can also cause the buttons to fall off during use.

[0004] Based on production needs, our company has designed and developed a smart terminal button with a self-locking function. This not only enables the button on the smart terminal to have a self-locking function, but also reduces the step of installing rubber rings, simplifies the production process, eliminates the rubber rings, reduces costs, and solves the problem of defective products caused by missing rubber rings in the machine. It is easy to assemble and has high production efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a smart terminal button with a self-locking function.

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

[0007] A smart terminal button with a self-locking function includes a terminal body and a button module, wherein the button module includes a button body and a spring.

[0008] The button body includes a cover and a rod that are connected to each other.

[0009] The terminal body has a movable groove that mates with the cover, and a self-locking sleeve for the locking rod is connected to the terminal body. The self-locking sleeve is elastic and includes an inner cavity that communicates with the movable groove.

[0010] The spring is placed in the movable groove, and the rod extends through the spring into the inner cavity of the self-locking sleeve. The rod moves within the inner cavity of the self-locking sleeve, and the rod cooperates with the self-locking sleeve. The two ends of the spring respectively abut against the cover and the inner wall of the bottom of the movable groove, and the cover moves within the movable groove.

[0011] A further configuration is provided whereby a protrusion is provided on the inner wall of the self-locking sleeve cavity, which abuts against the outer wall of the rod. The rod moves within the inner cavity of the self-locking sleeve, causing the protrusion to move along the length of the rod. An annular groove is provided on the outer peripheral wall of the rod, and the protrusion moves within the annular groove and engages with the annular groove.

[0012] Further configured, the self-locking sleeve includes two opposing arc-shaped pieces, the arc-shaped pieces are elastic, and there is a gap between the two arc-shaped pieces. The two arc-shaped pieces cooperate to form the inner cavity of the self-locking sleeve. Two protrusions are provided and respectively connected to the two arc-shaped pieces. The rod moves in the inner cavity of the self-locking sleeve and abuts against the protrusions to open the two arc-shaped pieces.

[0013] A further configuration is that the inner diameter of the self-locking sleeve is smaller than the diameter of the movable groove.

[0014] A further configuration is provided, wherein the lower end of the rod is connected to a guide block that facilitates the compression of the protrusion, the guide block being frustoconical in shape and moving within the inner cavity of the sleeve.

[0015] A further configuration is provided, wherein the protrusion includes a guide slope inclined toward the bottom of the sleeve, and the guide block abuts against the guide slope and moves on the guide slope.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows: while enabling the button module to achieve a self-locking function on the terminal body, the process of putting on the rubber ring is reduced, the rubber ring is eliminated, the cost is reduced, and the defective products caused by the machine missing the rubber ring are also solved.

[0022] The embodiments of this utility model will be further described with reference to Figures 1 to 4.

[0023] A smart terminal button with a self-locking function includes a terminal body 100 and a button module 200. The button module 200 includes a button body 1 and a spring 2. The button body 1 includes a cover 3 and a rod 4 connected to each other. The terminal body 100 has a movable groove 5 that mates with the cover 3. A self-locking sleeve 6 for locking the rod 4 is connected to the terminal body 100. The self-locking sleeve 6 is elastic and includes an inner cavity communicating with the movable groove 5. The spring 2 is placed in the movable groove 5. The rod 4... The spring 2 extends into the inner cavity of the self-locking sleeve 6. The rod 4 moves within the inner cavity of the self-locking sleeve 6. The two ends of the spring 2 abut against the inner wall of the bottom of the cover 3 and the movable groove 5, respectively. The cover 3 moves within the movable groove 5. The inner wall of the self-locking sleeve 6 is provided with a protrusion 7 that abuts against the outer wall of the rod 4. The rod 4 moves within the inner cavity of the self-locking sleeve 6, causing the protrusion 7 to move along the length of the rod 4. The outer peripheral wall of the rod 4 is provided with an annular groove 8. The protrusion 7 moves within the annular groove 8 and engages with the annular groove 8.

[0024] After the rod 4 passes through the spring 2, it extends into the inner cavity of the self-locking sleeve 6. The cover 3 is then pressed downwards, compressing the spring 2. The rod 4 moves downwards, causing its lower end to contact and press against the protrusion 7 inside the self-locking sleeve 6. The self-locking sleeve 6 is elastic, allowing the rod 4 to move downwards within the sleeve and engage with the protrusion 7, thus opening the sleeve. As the rod 4 moves downwards, the protrusion 7 moves along its length into the annular groove 8. At this point, the opened self-locking sleeve 6 rebounds, causing the protrusion 7 to engage with the annular groove 8. The pressure on the cover 3 is then released, and the compressed spring... 2. The spring 2 rebounds, causing the protrusion 7 to abut against the bottom inner wall of the annular groove 8, preventing the protrusion 7 from moving out of the annular groove 8. This achieves the locking effect of the self-locking sleeve 6 on the rod 4. Thus, when the cover 3 is not pressed, the spring 2, when it rebounds, will not cause the rod 4 to disengage from the self-locking sleeve 6. This achieves the self-locking fixation of the button module 200 on the terminal body 100. Pressing the cover 3 moves the rod 4 within the inner cavity of the self-locking sleeve 6 until the protrusion 7 enters the annular groove 8. Then, the force on the cover 3 can be removed, completing the assembly of the button module 200 on the terminal body 100. This process is simple and quick, eliminating the need for the rubber ring step.

[0025] When the button module 200 is in use, pressing the cover 3 causes the rod 4 to move downwards within the self-locking sleeve 6. At this time, the protrusion 7 moves along the length of the rod 4 within the annular groove 8. The protrusion 7 moves until it abuts against the top side wall of the annular groove 8, preventing it from moving out of the annular groove 8 and maintaining the connection between the rod 4 and the self-locking sleeve 6. When the pressure on the cover 3 is released, the spring 2 rebounds, causing the rod 4 to return to its original position and engage with the bottom inner wall of the annular groove 8, preventing the protrusion 7 from disengaging from the annular groove 8. This ensures that the rod 4 will not disengage from the self-locking sleeve 6, enabling the button module 200 to function normally on the terminal body 100. Ultimately, this achieves the self-locking function of the button module 200 on the terminal body 100 while reducing the step of installing the rubber ring, eliminating the rubber ring, reducing costs, and also solving the problem of defective products caused by the machine missing the rubber ring.

[0026] The self-locking sleeve 6 includes two opposing arc-shaped pieces 9. The arc-shaped pieces 9 are elastic and there is a gap between the two arc-shaped pieces 9. The two arc-shaped pieces 9 cooperate to form the inner cavity of the self-locking sleeve 6. Two protrusions 7 are provided and are respectively connected to the two arc-shaped pieces 9. The rod 4 moves in the inner cavity of the self-locking sleeve 6 and abuts against the protrusions 7 to open the two arc-shaped pieces 9.

[0027] When the rod 4 moves downward in the inner cavity of the self-locking sleeve 6, the rod 4 abuts against the protrusion 7 and opens the two elastic arc-shaped pieces 9, thereby achieving the purpose of opening the self-locking sleeve 6 when the rod 4 moves downward in the inner cavity of the self-locking sleeve 6. A gap is provided between the two arc-shaped pieces 9 to facilitate the rod 4 to open the two arc-shaped pieces 9 more smoothly through the protrusion 7, which facilitates the assembly of the button module 200 and the self-locking sleeve 6.

[0028] The inner diameter of the self-locking sleeve 6 is smaller than the diameter of the movable groove 5. When the cover 3 is pressed down and moves downward in the movable groove 5, the spring 2 can be compressed smoothly. When the pressing force on the cover 3 is removed, the spring 2 rebounds, which allows the cover 3 to return to its original position under the action of the spring 2. This avoids pressing the cover 3 with too much force and pressing it into the inner cavity of the self-locking sleeve 6, which would affect the reset of the button body 1.

[0029] The lower end of the rod 4 is connected to a guide block 10 that facilitates the compression of the protrusion 7. The guide block 10 is frustoconical, and the arc-shaped side of the guide block 10 abuts against the protrusion 7 to compress the protrusion 7. The end of the guide block 10 with a smaller bottom area corresponds to the bottom of the self-locking sleeve 6, and the guide block 10 moves within the inner cavity of the sleeve, which facilitates the lower end of the rod 4 to be smoothly squeezed between the two protrusions 7. Thus, when the rod 4 moves downward within the self-locking sleeve 6, the lower end of the rod 4 can be smoothly squeezed between the two protrusions 7 and compress the protrusion 7 to deform the self-locking sleeve 6 before continuing to move downward.

[0030] The protrusion 7 includes a guide slope 11 that slopes towards the bottom of the sleeve. The guide block 10 abuts against the guide slope 11 and moves on the guide slope 11, which further facilitates the smooth insertion of the lower end of the rod 4 between the two protrusions 7. When the rod 4 moves downward in the self-locking sleeve 6, the lower end of the rod 4 can be more smoothly inserted between the two protrusions 7 and squeeze the protrusions 7 to deform the self-locking sleeve 6 before continuing to move downward.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
