Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a push-button switch that prevents accidental touch. Background Technology

[0002] With the rapid development of intelligent and integrated technologies in electronic and mechanical equipment, push-button switches, as core control components, are widely used in various scenarios. In traditional technology, push-button switches mostly adopt an exposed design, relying on a simple pressing trigger mechanism to achieve circuit switching. However, due to the lack of effective protection measures, they are easily subject to accidental touches and misoperations in daily use, causing the switch to be triggered unexpectedly. This not only causes equipment to malfunction and interferes with normal working processes, but also presents a technical problem of poor anti-accidental touch effect of the switch. Utility Model Content

[0003] Therefore, it is necessary to provide a push-button switch that prevents accidental touch, addressing the technical problem of poor accidental touch prevention in switches.

[0004] An anti-accidental touch button switch includes: a control box, a switch, a rotating rod, a blocking block, and an elastic component. The switch is mounted on the control box. The rotating rod includes a connecting part and a guiding part. The connecting part is mounted on the control box, and a limiting groove is provided on the side of the connecting part facing away from the control box. The guiding part is connected to the connecting part. The blocking block includes a movable part, a protective part, and a limiting part. The movable part is rotatably connected to the guiding part and slides along the length direction of the guiding part. The protective part is connected to the movable part and correspondingly covers the switch. The limiting part is disposed on the side of the movable part near the limiting groove and is correspondingly engaged with the limiting groove. The elastic component is mounted on the guiding part and is used to provide the elastic force for the limiting part to engage in the limiting groove.

[0005] In one embodiment, the shielding block further includes a support portion connected to the end of the protective portion away from the movable portion and in contact with the control box.

[0006] In one embodiment, the protective part has a trademark groove on the side opposite to the switch.

[0007] In one embodiment, the central region of the movable part is provided with a movable hole, which is a circular hole, and the guide part is a circular rod.

[0008] In one embodiment, there are two limiting grooves, which are respectively disposed on opposite sides of the guide portion, and the number and position of the limiting portion correspond to the limiting grooves.

[0009] In one embodiment, the elastic component includes a blocking member and an elastic member. The blocking member is connected to the guide portion, and the elastic member is disposed between the blocking member and the movable portion. The elastic member is used to provide elastic force for the limiting portion to engage with the limiting groove.

[0010] In one embodiment, the elastic component further includes a protective cover disposed between the elastic member and the blocking member, and has a protective groove, with a portion of the elastic member disposed within the protective groove.

[0011] In one embodiment, the guide portion includes a rotating section and a mounting section, the diameter of the rotating section being larger than the diameter of the mounting section, the protective cover being mounted on the mounting section, and the blocking member being threadedly connected to the mounting section and driving the protective cover to abut against the rotating section.

[0012] In one embodiment, the connecting part includes a support rod, a connecting piece, and a fixing post. The diameter of the support rod is larger than the diameter of the guide part. The support rod passes through the control box and connects to the connecting piece. The connecting piece is disposed inside the control box and has a fixing hole that mates with the fixing post. The fixing post is connected to the control box and is used for a nut to mate with the control box to lock the connecting piece.

[0013] In one embodiment, the control box includes a box body, a box cover, and a control module. The box body has a mounting groove, a receiving cavity, and a fixing groove that are connected in sequence. The box cover is connected to the box body and closes the fixing groove. The control module is installed in the fixing groove. The switch is installed in the mounting groove. Part of the switch is located in the receiving cavity and is electrically connected to the control module.

[0014] The beneficial effects of the anti-accidental touch button switch provided in this application are as follows: A rotatable and sliding blocking block physically blocks the switch, effectively preventing accidental triggering caused by direct external contact. The locking mechanism between the limiting part and the limiting groove, combined with the elastic force provided by the elastic component, ensures the blocking block is stably locked in the non-operating state, guaranteeing the reliability of the protective function. The rotating rod's guide part and the movable part are connected by rotation and sliding, allowing the user to release the protection by rotating or sliding the blocking block. The operation requires applying a specific direction and force, significantly raising the threshold for accidental touch, thereby achieving the anti-accidental touch function and greatly improving the anti-accidental touch effect of the button switch without affecting normal operation.

[0034] like Figures 1 to 3 As shown, it is the anti-accidental touch button switch 100 of this utility model.

[0035] like Figures 1 to 3 As shown, the anti-accidental touch button switch 100 includes: a control box 10, a switch 20, a rotating rod 30, a blocking block 40, and an elastic component 50. The switch 20 is mounted on the control box 10. The rotating rod 30 includes a connecting part 31 and a guiding part 32. The connecting part 31 is mounted on the control box 10, and a limiting groove 311 is provided on the side of the connecting part 31 facing away from the control box 10. The guiding part 32 is connected to the connecting part 31. The blocking block 40 includes a movable part 41, a protective part 42, and a limiting part 43. The movable part 41 is rotatably connected to the guiding part 32 and slides along the length of the guiding part 32. The protective part 42 is connected to the movable part 41 and covers the switch 20 accordingly. The limiting part 43 is located on the side of the movable part 41 near the limiting groove 311 and is correspondingly engaged with the limiting groove 311. The elastic component 50 is mounted on the control box 10. The guide part 32 provides elastic force for the limiting part 43 to engage in the limiting groove 311. Through the rotatable sliding blocking block 40, the protective part 42 forms a physical barrier against the switch 20, effectively preventing accidental triggering caused by direct external contact with the switch 20. The locking cooperation between the limiting part 43 and the limiting groove 311, combined with the elastic force provided by the elastic component 50, ensures that the blocking block 40 is stably locked in the non-operational state, ensuring the reliability of the protective function. The guide part 32 of the rotating rod 30 is connected to the rotating sliding part 41, allowing the user to release the protection by rotating or sliding the blocking block 40. The operation process requires the application of a specific direction and force, significantly increasing the operation threshold for accidental touch, thereby achieving the anti-accidental touch function and achieving the purpose of greatly improving the anti-accidental touch effect of the button switch 20 without affecting normal operation.

[0036] The following text, combined with Figures 1 to 6 The above-mentioned anti-accidental touch button switch 100 will be further explained.

[0037] like Figures 1 to 2As shown, the control box 10 includes a box body 11, a cover 12, and a control module 13. The box body 11 has a mounting groove 111, a receiving cavity 112, and a fixing groove 113 connected in sequence. The cover 12 is connected to the box body 11 and closes the fixing groove 113. The control module 13 is installed in the fixing groove 113. The switch 20 is installed in the mounting groove 111, and some of the switches 20 are located in the receiving cavity 112 and are electrically connected to the control module 13. The switch 20, control module 13, and other components are housed in a layered design with mounting grooves 111, receiving cavities 112, and fixing grooves 113 within the box body 11. The components are rationally distributed in different cavities. The mounting slot 111 provides positioning and installation space for the switch 20. The receiving cavity 112 accommodates the connection part 31 of the switch 20 and provides wiring space. The fixing slot 113 protects the control module 13 from external interference. The closed design of the cover 12 improves the protection level of the control module 13 and prevents dust and liquid from entering and affecting the circuit of the control module 13. The modular installation of each component facilitates product assembly and later maintenance, while ensuring the stable electrical connection between the switch 20 and the control module 13, thereby improving the stability and reliability of the anti-accidental touch button switch 100.

[0038] To further improve the anti-accidental touch effect, reduce the load on the elastic component 50 and the limiting structure, and extend the service life of the blocking block 40, such as Figures 3 to 4 As shown, the shielding block 40 also includes a support part 44. The support part 44 is connected to the end of the protective part 42 away from the movable part 41 and contacts the control box 10. The shielding block 40 forms a multi-point support structure by connecting the support part 44 to the end of the protective part 42 away from the movable part 41 and contacting the control box 10. When the shielding block 40 is in the protective position, the support part 44 contacts the surface of the control box 10, which increases the stability of the shielding block 40 and prevents the shielding block 40 from tilting or shaking due to external force applied to the protective part 42. This more reliably maintains the covering state of the switch 20 and further improves the anti-accidental touch effect. At the same time, the support part 44 can disperse the pressure applied to the protective part 42 from the outside, thereby reducing the load on the elastic component 50 and the limiting structure and extending the service life of the shielding block 40.

[0039] like Figure 5 As shown, the protective part 42 has a trademark groove 421 on the side opposite to the switch 20. The design of the trademark groove 421 provides users with an area for label installation. The equipment brand logo, function logo, or operating instructions can be set in the trademark groove 421 to facilitate user identification and operation, and improve the human-computer interaction experience. At the same time, the setting of the trademark groove 421 does not affect the structural strength and protective function of the protective part 42. While achieving the goal of preventing accidental touch, it also meets the requirements of product appearance design and functional labeling, which can effectively enhance the practicality and market competitiveness of the product.

[0040] To improve the reliability and durability of the rotating rod 30, the blocking block 40, and the elastic component 50, such as Figure 4 As shown, the central region of the movable part 41 is provided with a movable hole 411, which is a circular hole. The guide part 32 is a circular rod. The circular hole in the central region of the movable part 41 serves as the movable hole 411. By engaging the movable hole 411 with the circular rod-shaped guide part 32, a stable rotation and sliding connection structure is formed. The engagement of the circular hole and the circular rod allows the movable part 41 to rotate freely around the guide part 32 and slide along the axis of the guide part 32. The movement resistance is small and the operation is smooth. This simple and reliable connection structure reduces the requirements for machining accuracy, facilitates mass production, and ensures the stability of the blocking block 40 during movement, avoiding shaking or jamming caused by excessive clearance. This achieves the purpose of improving the reliability and durability of the rotating rod 30, the blocking block 40, and the elastic component 50.

[0041] To further improve the effect of preventing accidental touches, such as Figure 6 As shown, there are two limiting grooves 311, which are respectively set on opposite sides of the guide part 32. The number and position of the limiting parts 43 are corresponding to the limiting grooves 311. The symmetrical limiting structure allows the blocking block 40 to be subjected to uniform elastic force when it is engaged, avoiding the phenomenon of the blocking block 40 tilting or jamming due to force on one side. When the user needs to operate the switch 20, he / she must simultaneously overcome the elastic force provided by the elastic component 50 to the limiting parts 43 on both sides, so that each limiting part 43 is disengaged from the limiting groove 311, in order to control the rotation of the blocking block 40. This increases the difficulty of accidental operation and further improves the anti-accidental operation effect.

[0042] To improve the service life of the elastic component 50, such as Figure 5 As shown, the elastic component 50 includes a blocking member 51 and an elastic member 52. The blocking member 51 is connected to the guide portion 32, and the elastic member 52 is disposed between the blocking member 51 and the movable portion 41. The elastic member 52 provides the elastic force for the limiting portion 43 to engage in the limiting groove 311. By employing the method of the elastic component 50 including the blocking member 51 and the elastic member 52, with the blocking member 51 connected to the guide portion 32 and the elastic member 52 disposed between the blocking member 51 and the movable portion 41, the elastic force provided by the elastic member 52 (such as a spring) pushes the movable portion 41. The limiting part 43 is engaged in the limiting groove 311 to lock the position of the blocking block 40. The elastic force of the elastic element 52 can be selected and adjusted according to actual needs to ensure that the engagement force between the limiting part 43 and the limiting groove 311 is moderate. This ensures the stability of the blocking block 40 in the non-operational state and makes it easy for the user to apply reasonable force to unlock it during normal operation. The blocking part 51 is used to limit the compression stroke of the elastic element 52 to prevent the elastic element 52 from being over-compressed and damaged, thereby improving the service life of the elastic component 50.

[0043] like Figure 3 and Figure 5 As shown, the elastic component 50 also includes a protective cover 53, which is disposed between the elastic element 52 and the blocking element 51 and has a protective groove 531. Part of the elastic element 52 is disposed in the protective groove 531. By adding a protective cover 53 between the elastic element 52 and the blocking element 51, the protective groove 531 of the protective cover 53 can accommodate part of the elastic element 52, which can effectively prevent the elastic element 52 from radially shifting or twisting during compression and extension, protect the normal working state of the elastic element 52, and thus effectively extend the service life of the elastic element 52. At the same time, the protective cover 53 provides physical protection for the elastic component 50, preventing external dust and debris from entering and affecting the performance of the elastic element 52, improving the environmental adaptability and reliability of the device. The design of the protective groove 531 provides guidance and limiting function for the elastic element 52, ensuring that the elastic force is uniformly transmitted along the axial direction of the guide part 32 and improving the stability of the limiting structure.

[0044] To improve the overall structural stability of the elastic component 50, such as Figure 6 As shown, the guide section 32 includes a rotating section 321 and an installation section 322. The diameter of the rotating section 321 is larger than the diameter of the installation section 322. The protective cover 53 is installed on the installation section 322. The blocking member 51 is threadedly connected to the installation section 322 and drives the protective cover 53 to abut against the rotating section 321. The position adjustment of the protective cover 53 is achieved through the threaded blocking member 51. The preload of the elastic component 50 can be adjusted according to the actual installation requirements. When the blocking member 51 is rotated, the protective cover 53 is pushed to abut against the rotating section 321, thereby compressing the elastic component 52 and adjusting the locking force between the limiting part 43 and the limiting groove 311. The threaded connection method has the advantages of reliable structure and convenient adjustment, which facilitates product assembly and subsequent maintenance. At the same time, the diameter difference between the rotating section 321 and the installation section 322 forms a limiting step to ensure accurate installation and positioning of the protective cover 53 and the blocking member 51, thereby improving the overall stability of the elastic component 50.

[0045] To improve the installation accuracy of the rotating rod 30, such as Figure 3 and Figure 6As shown, the connecting part 31 includes a support rod 312, a connecting piece 313, and a fixing post 314. The diameter of the support rod 312 is larger than the diameter of the guide part 32. The support rod 312 passes through the control box 10 and connects to the connecting piece 313. The connecting piece 313 is located inside the control box 10 and has a fixing hole 315 that mates with the fixing post 314. The fixing post 314 is connected to the control box 10 and is used for locking the connecting piece 313 with the nut. The connection between the connecting piece 313 and the fixing post 314 is achieved by locking with a nut to realize a detachable connection, which facilitates the assembly and maintenance of the equipment. The fixing post 314 inside the control box 10 ensures the installation accuracy of the rotating rod 30, ensures the accurate relative position of the guide part 32 and the switch 20, and enables the blocking block 40 to accurately cover the switch 20, thereby improving the installation accuracy of the rotating rod 30.

[0046] The working principle of the anti-accidental touch button switch 100 provided in this application is as follows: In the non-operating state, the elastic element 52 pushes the movable part 41, causing the limiting part 43 to engage with the limiting groove 311, and the protective part 42 covers the switch 20. The support part 44 contacts the control box 10 to form double protection, effectively preventing accidental touch. When the switch 20 needs to be operated, the user needs to pull the blocking block 40 upward along the axial direction of the guide part 32. The elastic element 52 of the elastic component 50 is compressed by force. At the same time, the limiting part 43 disengages from the limiting groove 311. Then, the blocking block 40 is rotated to the preset unlocking position (such as rotating 90°). At this time, the protective part 42 completely disengages from the blocking switch 20, making it easy to press the switch 20.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
