Abstract
Description
Technical field
[0001] The present invention relates to the technical field of adult products, specifically a multi-stage stretch control mechanism of a double handle. State of the art
[0002] Adult products are specifically designed for adults to satisfy their physiological needs, provide emotional comfort, or enhance intimacy experiences. Their intended use and function are clearly adult-oriented and not suitable for minors. The multi-stage stretching control function allows the user to adjust the length and shape of the masturbator's internal channel according to their preferences and sensitive areas, resulting in varying degrees of sensation and friction. For example, if stronger stimulation is desired, the mechanism can be adjusted to a specific section to make the internal structure more compact and intensify the sensation; if a milder experience is desired, it can be adjusted to a different section, altering the internal configuration and producing a different sensation.
[0003] With current technology, achieving a dual-handle design is difficult for some masturbators. Users may feel that certain sensations, such as interaction, are lacking during use, and that the experience lacks variety and realism. A dual-handle design can be better adapted to the physical conditions and usage habits of different users, helping to secure the masturbator's position and making it more stable during use. Without a dual-handle design, the masturbator's stability during use can be affected, requiring more effort from the user to maintain its position. This can easily impact comfort and ease of use, especially for individuals with specific physical conditions or usage patterns. Disclosure of the invention

Designs
[0020] The technical solution in the embodiments of the present invention is clearly and completely described below in conjunction with the illustrations of the present invention. Obviously, the described embodiments are only part of the embodiments of the present utility model and not the entirety of the embodiments. All other embodiments that could have been obtained by a person skilled in the art without inventive effort based on the embodiments specified in the present invention fall within the scope of protection of the present invention.
[0021] Combined with Fig. and Fig. The embodiment of the present invention provides a multi-stage extension control mechanism of a double handle, comprising two decorative covers (1). The decorative cover (1) can, as an outer protective and decorative part of the mechanism, completely cover the gap between the two outer casings (2) at the connection point, prevent the ingress of external dust, water vapor, and small impurities into the inner part of the mechanism, prevent erosion of the components, unify the style of appearance of the mechanism, avoid any impact on the aesthetics due to the exposure of the internal structure, and furthermore, dampen the collision force in the event of a slight external force impacting the mechanism, thus protecting the inner outer casing (2).On an adjacent side of the two decorative covers (1) outer housings (2) are firmly connected, on an adjacent side of the two outer housings (2) a support column (3) is firmly connected, in the inner part of the support column (3) several mounting holes for fastening the sliding steel shaft (59) are to be machined in order to provide a guide support for the back-and-forth sliding of the sliding detent sleeve (510) in the movement mechanism (5), to ensure the linearity and stability of the extension action;A key mechanism (4) is arranged on a front side of the support column (3). The key mechanism (4) is a core interaction module for the user to actuate the mechanism. The switching on and off of the internal circuit is to be triggered by the pressing action of the silicone button (41), so that the user's operating command is converted into an electrical signal, transmitted to the control unit, and then the operating parameters of the movement mechanism (5) and the detent vibration mechanism (6) are controlled by the control unit based on the signal.A movement mechanism (5) is arranged on a rear side of the support column (3). The movement mechanism (5) is the core implementation module for enabling the multi-stage expansion function of the mechanism. The drive force is output by the 130 motor. After the change in speed and torque by the transmission of the gear group, the round plate (55) is driven to rotate. The rotary motion is then converted into a back-and-forth linear motion of the sliding detent sleeve (510) along the sliding steel shaft (59). Using the multi-stage limiting design of the sliding steel shaft (59), switching between different expansion strokes is made possible to meet the simulation needs of the mechanism for dynamic depth changes.Within a base part of the two outer housings (2) a detent vibration mechanism (6) for back-and-forth gripping is arranged, the detent vibration mechanism (6) is supplied with continuous, stable drive force by the reduction gear motor I (62), by means of a transmission component the pivot arm assembly I (66) is driven to move back and forth for opening and closing, then the detent soft rubber (612) on the ring platform (611) is pressed by the pivot arm assembly I (66) so that the detent soft rubber (612) generates a clamping grip action to improve the degree of fit of the mechanism with the contacted object, to ensure the reliability and stability of the grip action;
[0022] combined with Fig. until Fig. The detent vibration mechanism (6) comprises a box (61), a bottom part of the box (61) is rigidly connected to an inner wall of the bottom part of the two outer housings (2), an inner part of the box (61) is rigidly connected to a reduction gear motor I (62), the reduction gear motor I (62) is the drive source of the detent vibration mechanism (6), a built-in reduction gear assembly can convert the high speed, low torque into a low speed, high torque to provide sufficient drive force for the detent action to ensure that the detent soft rubber (612) can be driven by the pivot arm assembly I (66) to generate the stable clamping force, at the same time the speed of the motor can be regulated due to the control signal, the frequency and force of the detent action are changed;A drive end of the reduction gear motor I (62) is rigidly connected to a round plate II (63). The round plate II (63) is the first key component for transmitting the drive force of the reduction gear motor I (62). It is rigidly connected to the drive end of the motor by means of a central bore and fully transmits the rotary motion of the motor. Then, with the help of the cylinder II (64) attached to the front, the rotary motion is converted into the drive force for sliding the limit bracket (68) to ensure the transmission of the drive force without loss. At the same time, the flat structure of the round plate II (63) ensures the stability of the movement path of the round plate II (63).The front of the round plate II (64) is rigidly connected to a cylinder II (64), the cylinder II (64) is attached perpendicularly to a front edge position of the round plate II (63), makes a circumferential movement with the rotation of the round plate II (63), during the movement process the outer wall of the cylinder II (64) continuously contacts with the limiting bracket (68) and exerts a thrust force, the circumferential movement is converted into a linear movement of the limiting bracket (68) along the support column (67) and the cylindrical structure of the cylinder II (64) can reduce the friction when in contact with the limiting bracket (68), ensure a smooth thrust process, avoid interruption;The inner part of the box (61) is firmly connected on the left and right sides to a mounting shaft (65), the mounting shaft (65) is a rotation support shaft of the pivot arm assembly I (66), with both ends each attached in a mounting bore on the left and right inner wall of the box (61), so that the pivot arm assembly I (66) is continuously rotated around the mounting shaft (65) during the opening and closing process, and no displacement or fluctuation can occur;
[0023] combined with Fig. A pivot arm assembly I (66) is rotatably connected outside the mounting shaft (65). The pivot arm assembly I (66) is a direct implementing part of the detent action, which is rotatably connected to the mounting shaft (65) at one end by means of a shaft bore, and extends at another end to the inside of the detent rubber (612). Driven by the limiting bracket (68), it pivots back and forth around the mounting shaft (65) to open and close. During pivoting, the detent rubber (612) is pressed or released by means of its own outer wall together with the vibration motor (610), thereby deforming the detent rubber (612) and causing the clamping action. At the same time, the length and pivot angle of the pivot arm assembly I (66) are to be precisely designed to ensure that a clamping grip area of the detent rubber (612) meets the requirements.The inner part of the box (61) is rigidly connected to a limiting component (613) for support; the limiting component (613) is the core of the transmission connection of the ratchet vibration mechanism (6), and consists of the support column (67), the limiting bracket (68), and the limiting rod (69). The support column (67) provides a sliding guide for the limiting bracket (68), preventing the limiting bracket (68) from displacing during sliding. The limiting bracket (68) receives the thrust force of cylinder II (64) and transmits it to the limiting rod (69). The limiting rod (69) then converts the linear motion into the rotary motion of the swivel arm assembly I (66) to ensure a stable, effective transmission path from the motor to the swivel arm assembly I (66).A head part of the box (61) is rigidly connected to a ring platform (611), the ring platform (611) is the base for the arrangement and support of the locking rubber (612), the outer wall of which is to fit tightly against the inner wall of the locking rubber (612) to ensure that the locking rubber (612) cannot be displaced after fastening, at the same time the ring-shaped structure of the ring platform (611) can provide a uniform support force for the locking rubber (612) so that the locking rubber (612) can be uniformly deformed along a ring-shaped path when pressed by the swivel arm group I (66), ensuring the symmetry and stability of the clamping action;wherein a vibration motor (610) is rigidly connected to an outer part of one of the swivel arm group I (66), the vibration motor (610) is attached at a specific position of the swivel arm group I (66), which mainly serves to increase the contact area of the swivel arm group I (66) with the locking soft rubber (612), to avoid the local excessive wear of the soft rubber due to the single-point contact of the swivel arm group I (66) with the locking soft rubber (612), to enable a uniform distribution of the pressure force of the locking soft rubber (612) through the swivel arm group I (66), to ensure a corresponding deformation of the locking soft rubber (612), and to increase the degree of fit and the reliability of the clamping grip;
[0024] A soft rubber stop (612) is attached to an outer part of the ring platform (611). The soft rubber stop (612) is made of an elastic material and is a component that makes direct contact with the clamped object. Its elastic deformation enables the clamping action, which not only prevents damage to the object from the rigid clamping action but also fills the fine indentations on the object's surface through deformation, thus improving the contact feel. At the same time, the soft rubber material has a certain wear resistance, extending the service life of the clamping component and ensuring stable clamping performance even after long-term use. The limiting component (613) includes two support columns (67), which are vertically attached to the inner wall of the bottom part of the box (61).Two support columns (67) are arranged parallel to each other, and their spacing matches the width of the limiting bracket (68). The outer wall of the support columns requires a smooth finish to reduce frictional resistance with the inner wall of the limiting bracket (68) to ensure that the limiting bracket (68) can slide smoothly along the support column (67). At the same time, the support column (67) must have sufficient stiffness to prevent bending or deformation during the shearing process of the limiting bracket (68). An outer part of the two support columns (67) is rigidly connected to the inner part of the box (61). The outer part of the two support columns (67) is slidably connected to a limiting bracket (68). The limiting bracket (68) is a core transmission part of the limiting component (613). A sliding bore matching the support column (67) is machined inside the limiting bracket (68).The limiting bracket (68) can slide linearly along the support column (67), contacts the cylinder II (64) at the front, receives the thrust force, is connected to the swivel arm assembly I (66) at both sides by attaching the limiting rod (69), can convert the linear motion into the rotary motion of the swivel arm assembly I (66), limiting rods (69) are rigidly connected internally to the front and rear of the limiting bracket (68), the limiting rod (69) is a cylindrical structure, with both ends attached to the front and rear of the limiting bracket (68), and embedded with a central section in a sliding recess of the swivel arm assembly I (66), serves to establish a transmission connection between the limiting bracket (68) and the swivel arm assembly I (66) when the limiting bracket (68) slides.The limiting rod (69) slides within the sliding recess of the swivel arm assembly I (66) and drives the swivel arm assembly I (66) around the mounting shaft (65) to rotate;
[0025] combined with Fig. and Fig. The key mechanism (4) comprises a silicone key (41). The back of the silicone key (41) is positioned on the front of the two outer housings (2). The front of the silicone key (41) is firmly connected to a key decoration part (42). The key decoration part (42) covers a front surface of the silicone key (41) and is made of a hard material. This protects the silicone key (41) from external scratches and impact damage, thus extending its service life. Furthermore, the key decoration part allows for printing or engraving markings on its surface, clearly indicating the key's function to facilitate user recognition and operation. The outer part of the key decoration part (42) is firmly connected to a key light shield (43). The key light shield (43) has a ring structure and ensures that the user can clearly identify the key and accurately complete the actuation.to ensure the stability of command input;
[0026] combined with Fig. , Fig. and Fig. The movement mechanism (5) comprises a roller gear housing (51). A front face of the roller gear housing (51) is rigidly connected to the rear of the support column (3). A 130 motor (52) is rigidly connected to a right-hand inner wall of the roller gear housing (51). The 130 motor (52) is the drive source of the movement mechanism (5). Based on the signal from the control unit, the input speed and steering can be regulated. The 130 motor (52) provides a continuous drive force to the gear assembly. The output shaft of the 130 motor is rigidly connected to the secondary gear I (53). The rotational drive force can be directly transmitted to the secondary gear I (53) to ensure effective drive transmission without significant loss. An inner part of the roller gear housing (51) is rotatably connected to a secondary gear I (53).Secondary gear I (53) is a primary transmission gear of the motion mechanism (5). The number of teeth and modules are precisely designed. After being rigidly connected to the output shaft of the 130 motor (52), the high speed of the motor can be reduced to a speed suitable for secondary gear II (54). Simultaneously, the direction of the drive transmission is changed so that the drive force can be smoothly transmitted to secondary gear II (54). The inner part of the roller gearbox housing (51) is rotatably connected to secondary gear II (54). Secondary gear II (54) is a secondary transmission gear of the motion mechanism (5). It has more teeth than secondary gear I (53), which can further reduce the transmission speed and increase the torque. Secondary gear II (54) is also engaged with secondary gear I (53) and a wobble gear (56).The roller gear housing (51) fulfills the function of drive transmission, precisely transmitting the drive force transmitted by the secondary gear I (53) to the wobble gear (56). The roller gear housing (51) is rotatably connected to a round plate I (55) at its front inner wall and fixedly connected to a wobble gear (56) at a rear side of the round plate I (55). It rotates synchronously with the wobble gear (56). The cylinder I (58), attached to the front edge, makes a circumferential movement with it. The rotational movement of the wobble gear (56) can be converted into a periodic thrust force for the ring frame (11). At the same time, the flatness of the round plate I (55) must be strictly controlled to ensure that the path of motion of the cylinder I (58) is a standardized circular shape, in order to prevent the uneven thrust force from interrupting the movement of a sliding detent sleeve (510). A wobble gear (56) is firmly connected to a rear side of the round plate I (55),The wobble gear (56) is a final transmission gear of the motion mechanism (5), engages with secondary gear II (54), receives the driving force, the number of teeth matches secondary gear II (54) to ensure that the driving force transmitted by secondary gear II (54) is stably received and that the round plate I (55) can be driven to rotate, simultaneously a rear face of the wobble gear (56) contacts a gear disc (57), which reduces friction with the inner wall of the roller gear housing (51) during rotation, ensures frictionless rotation, thus preventing loss of driving force or overheating of the components due to excessive friction; the rear face of the wobble gear (56) is rigidly connected to a gear disc (57) to extend the service life of the wobble gear (56) and the housing;
[0027] A cylinder I (58) is rigidly connected to a front face of the round plate I (55). The round plate I (58) is attached perpendicularly to the front edge of the round plate I (55). During circumferential movement with the round plate I (55), the outer wall of the cylinder I (58) can continuously contact the inside of the ring frame (511). Periodic thrust and tensile forces are exerted on the ring frame (511). The ring frame (511) is pushed and drives the sliding detent sleeve (510) to move back and forth along the sliding steel shaft (59). At the same time, the outer wall of the cylinder I (58) should be smooth to reduce the frictional resistance when in contact with the ring frame (511) and to ensure the stable transmission of the thrust force. Within the support column (3) several sliding steel shafts (59) are firmly connected, the sliding steel shaft (59) is a sliding guide part of the sliding detent sleeve (510), manufactured by means of a linear optical shaft of high precision,The surface has a high degree of smoothness; several sliding steel shafts (59) are parallel and evenly distributed within the support column (3), not only providing a linear slide rail for the sliding locking sleeve (510) and limiting its direction of movement, but also realizing a multi-stage stroke limitation by arranging a limiting projection at a specific position on the shaft body, so that the sliding locking sleeve (510) can move back and forth within different stroke ranges, thus fulfilling the need for multi-stage extension of the mechanism; a sliding locking sleeve (510) is slidably connected to an outer part of the several sliding steel shafts (59); the sliding locking sleeve (510) is an extension design part of the movement mechanism (5), within which a sliding bore matching the sliding steel shaft (59) is machined; the sliding locking sleeve (510) can slide smoothly along the sliding steel shafts (59).Externally, a ring frame (511) is attached to receive the thrust force of cylinder I (58). Inside the sliding detent sleeve (510), the rolling rubber (512) is attached. The rolling rubber (512) can be driven synchronously with the reciprocating linear movement. Outside the sliding detent sleeve (510), a ring frame (511) is rigidly connected. The ring frame (511) is a ring structure, mounted outside the sliding detent sleeve (510) and rigidly connected to it. The inside of the ring frame (511) contacts cylinder I (58) and can uniformly transmit the periodic thrust force exerted by cylinder I (58) to the sliding detent sleeve (510), driving the sliding detent sleeve (510) to slide along the sliding steel shafts (59). Inside the sliding detent sleeve (510), a rolling rubber (512) is rigidly connected.

[0031] In the ratchet vibration mechanism (6) the drive force is supplied by a reduction gear motor (62), the round plate II (63) is driven to rotate, the cylinder II (64) on the round plate II (63) is rotated with it and pushes the limiting bracket (68) to slide along the support column (67). The limiting rods (69) on both sides of the limiting bracket (68) are each embedded in a recess of a left and right pivoting arm group I (66). When the limiting bracket (68) slides, the pivoting arm group I (66) is driven to pivot back and forth around the mounting shaft (65) in an opening and closing direction. The pressing and releasing of the detent rubber (612) outside the ring platform (611) by the pivoting arm group I (66) and the vibration motor (610) results in a double-grip action of the detent rubber (612) similar to a clamping action, improving the feel of the contact.
[0032] In the key mechanism (4), the silicone key (41) serves as an operating interface; when pressed, an internal circuit signal can be triggered, the signal is transmitted to the control unit of the movement mechanism (5) and the detent vibration mechanism (6), thus regulating the speed and steering of the 130 motor and the reduction gear motor I (62); by changing the motor parameters, the frequency, the amplitude of the extension of the rolling soft rubber (512), as well as the detent force and the rhythm of the detent soft rubber (612) can be precisely controlled; furthermore, the key light shield (43) can reduce interference with key operation caused by external light to ensure the stability of command input.
[0033] In another embodiment, the reduction gear motor II (615) in the detent vibration mechanism (6) provides the drive force, drives the eccentric drive wheel (616) to rotate, the eccentric drive wheel (616) is rotated and pushes the support bracket (618) to slide along the limiting shaft (617), the sliding columns (620) on both sides of the limiting shaft (617) are each embedded in the recess of the left and right pivot arm assembly II (621), when the support bracket (618) slides, the left and right pivot arm assembly II (621) can be driven to pivot back and forth around the sliding column (620) in an opening and closing manner, the pressing and releasing of the detent rubber (612) outside the ring platform (611) by the pivot arm assembly II (621) and the vibration motor (610) causes the detent rubber to (612) generates a double-handle clamping action, the reduction gear motor II (615) drives the eccentric drive wheel (616),The eccentric drive wheel (616) pushes a sliding piece, drives the left and right pivot arm group II (621), namely the mechanism that moves left, right, forward and backward. When the pivot arm group I (621) moves forward and backward, due to the function of the rotating shaft (619), an opening and closing action occurs simultaneously with a forward and backward movement; the opening is changed by an angular size of the pivot arm group II (621).
