Description

Technical Field

[0001] This utility model belongs to the technical field of reversing speed control switches, specifically relating to an anti-sway large button assembly structure for small-volume reversing speed control switches. Background Technology

[0002] Currently, common reversing speed control switches typically feature single-finger operation buttons and small switch bodies. While these small buttons are sufficient for most end-user applications, some require larger buttons that allow for multi-finger operation, providing a more comfortable feel and control. However, when such large buttons are paired with small switch bodies, multi-finger operation can lead to uneven pressure on the button, potentially causing abnormal internal output signals. This could result in motor malfunctions such as failing to rotate. Therefore, using large buttons with small switch bodies presents a technical challenge: reduced switch control precision. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an anti-sway large button assembly structure for small-volume commutation speed control switches, thereby solving the technical problem of reduced switch control accuracy when using large buttons in conjunction with small-volume switch bodies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an anti-sway large button assembly structure applied to a small-volume reversing speed control switch, including a switch body and a button. A push rod is connected to the switch body, and the button is connected to the outer end of the push rod for pressing the push rod to control the opening and closing of the switch and speed regulation. The upper end of the button is located above the switch body, and the lower end of the button is located below the switch body. An upper guide plate and a lower guide plate extending towards the button are provided on the outer shell of the switch body. The upper guide plate and the lower guide plate are respectively located on both sides of the push rod and are parallel to the axial direction of the push rod. A guide groove corresponding to and adapted to the upper guide plate and the lower guide plate is opened at the end of the button facing the outer shell. When the button is installed on the push rod, the upper guide plate and the lower guide plate are inserted into the guide groove one by one, guiding the button to move along the axial direction of the push rod.

[0005] As a preferred embodiment, the top of the switch body is also provided with a reversing mechanism. The upper guide plate and the lower guide plate are respectively located on the upper and lower edges of the outer shell. A rotating shaft is integrally formed on the top surface of the upper guide plate located on the upper edge of the outer shell. A lever for driving the reversing mechanism is sleeved on the rotating shaft. The upper guide plate is provided with slots parallel to the axial direction of the push rod on both sides. A retaining strip is provided on the inner wall of the guide groove that is adapted to the upper guide plate. When the upper guide plate is inserted into the corresponding guide groove, the retaining strip is inserted into the slot.

[0006] As a preferred embodiment, a limiting groove is provided on the bottom surface of the lower guide piece, the axis of the limiting groove is parallel to the axis of the push rod, and a limiting strip adapted to the limiting groove is provided on the bottom surface of the button. When the lower guide piece is inserted into the corresponding guide groove, the limiting strip is slidably inserted into the limiting groove.

[0007] As a preferred embodiment, the top ends of the two side walls of the button extend upward to form receiving grooves for accommodating the lever, the rear end of the lever is inserted into the receiving groove and extends backward to the outside of the button, and there is a gap between the lever and the two side walls of the receiving groove.

[0008] As a preferred embodiment, the outer casing has a self-locking hole on its side, the axis of which is parallel to the axis of the push rod. A locking piece extending into the self-locking hole is provided on one side wall of the button. When the button is installed on the push rod, the locking piece is inserted into the self-locking hole and slidably connected with it. The self-locking hole and the locking piece are compatible.

[0009] The beneficial effects of this utility model are as follows: By setting upper and lower guide plates to guide the button simultaneously, this utility model reduces the sway amplitude of the button when it receives lateral force, thereby avoiding the problem of unstable switch opening / closing and speed regulation states caused by the push rod being deflected by the button. It also improves the structural stability when a large-volume button is used with a small-volume switch body, solving the technical problem of decreased switch control accuracy when using a large button with a small-volume switch body.

[0010] This invention further increases the tightness of the connection between the upper guide piece and the corresponding guide groove by setting mutually cooperating slots and strips, thereby further reducing the sway amplitude of the upper guide piece in the corresponding guide groove.

[0011] This invention further enhances the lateral positioning capability of the lower guide plate and the button by setting a limiting groove and a limiting strip, thereby further preventing the lower end of the button from swaying.

[0012] This invention further improves the connection stability between the button and the housing by setting a self-locking hole and a locking plate, thereby reducing the risk of the button deflecting under multi-finger operation. Attached Figure Description

[0014] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0015] like Figures 1-4 The illustrated anti-sway large button assembly structure for a small-volume reversing speed control switch includes a switch body and a button 1. A push rod 2 is connected to the switch body, and the button 1 is connected to the outer end of the push rod 2 for pressing the push rod 2 to control the opening and closing of the switch and speed regulation. The upper end of the button 1 is located above the switch body, and the lower end of the button 1 is located below the switch body. The overall height of the button 1 is greater than the height of the switch body. The outer shell 3 of the switch body is provided with an upper guide plate 4 and a lower guide plate 5 extending towards the button 1. The upper guide plate 4 and the lower guide plate 5 are respectively located on both sides of the push rod 2 and are parallel to the axial direction of the push rod 2. The end of the button 1 facing the outer shell 3 has a guide groove 6 that corresponds to and fits the upper guide plate 4 and the lower guide plate 5. When the button 1 is installed on the push rod 2, the upper guide plate 4 and the lower guide plate 5 are inserted into the guide groove 6 one-to-one, guiding the button 1 to move along the axial direction of the push rod 2.

[0016] Under the combined guidance and limiting effect of the upper guide plate 4 and the lower guide plate 5, the deflection of button 1 when subjected to lateral force is significantly reduced, thereby avoiding the technical problems of abnormal opening and closing and speed regulation functions and reduced control accuracy caused by the deflection of button 1 driving push rod 2.

[0017] The top of the switch body is also provided with a reversing mechanism 7. The upper guide plate 4 and the lower guide plate 5 are respectively located on the upper and lower edges of the outer shell 3. A rotating shaft 8 is integrally formed on the top surface of the upper guide plate 4 located on the upper edge of the outer shell 3. A lever 9 for driving the reversing mechanism 7 is sleeved on the rotating shaft 8. The upper guide plate 4 is provided with slots 10 parallel to the axial direction of the push rod 2 on both sides. The inner wall of the guide groove 6 that is adapted to the upper guide plate 4 is provided with a locking strip 11 that is adapted to the slot 10. When the upper guide plate 4 is inserted into the corresponding guide groove 6, the locking strip 11 is inserted into the slot 10.

[0018] The addition of the card slot 10 and the card strip 11 increases the complexity of the connection structure between the upper guide piece 4 and the corresponding guide groove 6, thereby increasing the difficulty of the upper guide piece 4 swaying within the corresponding guide groove 6 and further reducing the risk of button 1 swaying.

[0019] In this embodiment, a limiting groove 12 is also provided on the bottom surface of the lower guide piece 5. The axis of the limiting groove 12 is parallel to the axis of the push rod 2. A limiting strip 13 adapted to the limiting groove 12 is provided on the bottom surface of the button 1. When the lower guide piece 5 is inserted into the corresponding guide groove 6, the limiting strip 13 is slidably inserted into the limiting groove 12.

[0020] The cooperation between the limiting strip 13 and the limiting groove 12 can further reduce the left and right offset caused by the left and right side gap between the lower guide plate 5 and the corresponding guide groove 6.

[0021] In this embodiment, the top of the two side walls of the button 1 extends upward to form a receiving groove 14 for accommodating the lever 9. The rear end of the lever 9 is inserted into the receiving groove 14 and extends backward to the outside of the button 1 so that the user can directly move the lever 9 from the outside of the button 1. There is a gap between the lever 9 and the two side walls of the receiving groove 14.

[0022] like Figure 3 As described above, a self-locking hole 15 is provided on the side of the outer casing 3, and the axis of the self-locking hole 15 is parallel to the axis of the push rod 2, such as... Figure 4 As shown, a locking piece 16 extending into the self-locking hole 15 is provided on one side wall of button 1. When button 1 is installed on push rod 2, the locking piece 16 is inserted into the self-locking hole 15 and slidably connected with the self-locking hole 15. The self-locking hole 15 and the locking piece 16 are adapted to each other. The locking piece 16 can also improve the connection stability between button 1 and housing 3 and reduce the risk of button 1 deflection under multi-finger operation.

[0023] The working process of this utility model is as follows: Figures 1-4 The assembly structure shown is for a large anti-sway button used in a small-volume reversing speed control switch. When using it, first press... Figures 1-4 When button 1 is assembled, during use, the user can press button 1 with multiple fingers. When button 1 receives lateral force, the upper guide plate 4 and the lower guide plate 5 can jointly suppress the button 1 from swaying and guide the button to move along the axial direction of the push rod 2, thereby avoiding the push rod 2 from being deflected by button 1, which would lead to a decrease in switch control accuracy.

[0024] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
