Description

Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, specifically to an environmentally friendly, detachable teaching head. Background Technology

[0002] In hairdressing, training heads are needed. Traditional training heads are usually made of PVC material to form a scalp, into which suitable hair is inserted, and then sealed with polyurethane foam to form a training head product, so that learners can practice hairdressing. Since traditional training head products are usually a whole structure, each training head product produces a residue after use, and the whole training head needs to be discarded, which easily causes waste and environmental problems. Utility Model Content

[0003] The purpose of this invention is to provide an environmentally friendly, detachable teaching head, which allows for easy installation and disassembly of the teaching head's partial structure, thereby reducing environmental pollution and waste caused by discarding the entire head.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly, detachable training head, comprising:

Each positioning pin is connected to each positioning hole.

[0037] Compared with existing technologies, when using the above technical solution, when a new head assembly needs to be installed, the operator only needs to align and fasten the first locking component inside the head assembly with the second locking component inside the head mold body, so that the first locking component is in the locked position relative to the second locking component, thus completing the installation and fixation between the head assembly and the head mold body; when the head assembly needs to be replaced after use, the unlocking mechanism drives the second locking component to move, so that the second locking component is in the unlocked position relative to the first locking component, at which point the first locking component and the second locking component are in the unlocked position. The components are separated, completing the unlocking action. At this point, the top component can be removed for replacement. Compared to the traditional teaching head with an integral structure, this application adopts a separate structure of the head mold body and the top component. The head mold body and the top component are connected by a first locking component, a second locking component, and an unlocking mechanism, which makes it easy to install and disassemble the top component and the head mold body. When a top component is used up, only a part of the teaching head structure can be replaced, that is, only the top component is replaced, without having to discard the entire teaching head after use, avoiding environmental pollution and waste, and making operation convenient.

[0047] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0050] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] like Figures 1-6 As shown in the figure, this utility model embodiment provides an environmentally friendly detachable training head, hereinafter referred to as the training head. It includes: a base 1, a head mold body 2, a top assembly 3, a first locking component 4, a second locking component 5, and an unlocking mechanism 6.

[0053] The head mold body 2 is connected to the base 1; the top head assembly 3 is detachably connected to the head mold body 2 and can be combined to form a hollow head structure; the first locking component 4 is located inside the head structure and is fixed to the top head assembly 3; the second locking component 5 is located inside the head structure and is fixed to the head mold body 2, and the second locking component 5 has a locking position and an unlocking position relative to the first locking component 4. When the second locking component 5 is in the locking position, the first locking component 4 and the second locking component 5 are locked; when the second locking component 5 is in the unlocking position, the first locking component 4 and the second locking component 5 are unlocked; the unlocking mechanism 6 is located inside the head structure, and the unlocking mechanism 6 is linked with the second locking component 5 to drive the second locking component 5 to switch between the locking position and the unlocking position.

[0054] In specific implementation, such as Figure 1As shown, when a new head assembly 3 needs to be installed, the operator only needs to align and engage the first locking component 4 inside the head assembly 3 with the second locking component 5 inside the head mold body 2, so that the first locking component 4 is in the locked position relative to the second locking component 5, thus completing the installation and fixation between the head assembly 3 and the head mold body 2. When a head assembly 3 is used up and needs to be replaced, the unlocking mechanism 6 drives the second locking component 5 to move, so that the second locking component 5 is in the unlocked position relative to the first locking component 4, at which point the first locking component 4 and the second locking component 5 separate. After unlocking, the top component 3 can be removed for replacement. Compared to the traditional integrated structure of the teaching head, this application adopts a separate structure of the head mold body 2 and the top component 3. The head mold body 2 and the top component 3 are connected by a first locking component 4, a second locking component 5 and an unlocking mechanism 6, which makes it easy to install and remove the top component 3 from the head mold body 2. After using one top component 3, only a part of the teaching head structure can be replaced, that is, only the top component 3 needs to be replaced. There is no need to discard the entire teaching head after use, which avoids environmental pollution and waste and is convenient to operate.

[0055] like Figures 2-4 As shown, specifically in this embodiment, the first locking component 4 includes a locking sleeve, and the side wall of the locking sleeve is provided with a insertion hole 41. The insertion hole 41 is used to cooperate with the second locking component 5 to complete locking or unlocking. When the second locking component 5 is in the locked position, the second locking component 5 is inserted into the insertion hole 41. When the second locking component 5 is in the unlocked position, the second locking component 5 is disengaged from the insertion hole 41. The unlocking mechanism 6 includes an unlocking sleeve 61, which can be axially moved and cooperated with the lower port of the locking sleeve, that is, the unlocking sleeve 61 can extend into the locking sleeve. Through the movement of the unlocking sleeve 61 and the linkage cooperation with the second locking component 5, the second locking component 5 is inserted into or disengaged from the insertion hole 41.

[0056] The working process is as follows: When installing the head assembly 3, the operator aligns the lower end of the locking sleeve with the axial direction of the unlocking sleeve 61 and moves it downwards along the axial direction of the unlocking sleeve 61, gradually approaching the second locking component 5 until the insertion hole 41 aligns with the second locking component 5. At this time, the unlocking sleeve 61 moves downwards and disengages from the second locking component 5. The second locking component 5 is then inserted radially into the insertion hole 41 of the locking sleeve, completing the locking action. At this point, the head assembly 3 and the head mold body 2 are combined as one unit. When unlocking is required, the operator drives the unlocking sleeve 61 to move upwards along its axial direction and gradually approaches the second locking component 5 inserted into the insertion hole 41 of the locking sleeve. The second locking component 5 is then pushed out radially and disengaged from the insertion hole 41, completing the unlocking action. At this point, the operator can move the locking sleeve and the head assembly 3 upwards together and remove them from the head mold body 2. The detachable design between the locking sleeve and the unlocking sleeve 61 allows for partial replacement of the head assembly 3 and the head mold body 2, improving the ease of installation and operation of the training head.

[0057] In some embodiments, there may be one or more insertion holes 41, such as two, three, or four. When there are multiple insertion holes 41, they are spaced apart circumferentially on the sidewall of the locking sleeve, and each insertion hole 41 corresponds to a second locking component 5 to complete locking or unlocking. This arrangement, through multiple insertion fixing positions, ensures that the force at the connection between the top assembly 3 and the head mold body 2 is uniform, guaranteeing the reliability and stability of the connection structure, reducing the risk of structural damage at a single locking position, and extending the service life of the teaching head.

[0058] like Figure 3 and Figure 4 As shown, specifically in this embodiment, the second locking component 5 includes: a fixing block 51, a sliding rod 52, a contact head 53, and a first elastic element. The fixing block 51 is fixed to the head mold body 2, and the fixing block 51 has a sliding channel. The sliding rod 52 passes through the sliding channel and is slidably connected to the fixing block 51. The contact head 53 is fixedly connected to one end of the sliding rod 52 near the locking sleeve. The contact head 53 is used to slide into the insertion hole 41 after sliding contact with the lower end of the locking sleeve. The contact head 53 is also used to slide out of the insertion hole 41 after sliding contact with the upper end of the unlocking sleeve 61. The first elastic element is sleeved with the sliding rod 52, and the first elastic element acts on the contact head 53 and the fixing block 51 to apply a force to the contact head 53 along the axial direction of the sliding rod 52 away from the fixing block 51. The first elastic element can be a compression spring or an elastic rubber sleeve, as long as it can provide a force away from the fixing block 51, and is not limited to the forms listed in this embodiment.

[0059] During operation, the operator gradually moves the lower end of the lock sleeve closer to the contact head 53. The lower end of the lock sleeve slides into contact with the contact head 53. As the lock sleeve moves downward, under the guidance of the end face (such as a conical surface, inclined surface, arc surface, or convex surface) of the contact head 53, the lower end of the lock sleeve pushes the contact head 53 away from the lock sleeve along the radial direction of the lock sleeve. The contact head 53 drives the sliding rod 52 to slide away from the lock sleeve along the sliding channel of the fixed block 51. At this time, the first elastic element is compressed. When the lock sleeve moves to the position corresponding to the insertion hole 41 and the contact head 53, due to the force exerted on the contact head 53 by the first elastic element, the contact head 53 extends into the insertion hole 41, completing the locking action. The lower surface of the contact head 53 limits the insertion hole 41, and the lock sleeve cannot move upward. The operator inserts the upper end of the unlocking sleeve 61 into the lock sleeve and gradually moves it upwards towards the contact head 53. The upper end of the unlocking sleeve 61 slides into contact with the end face of the contact head 53. As the unlocking sleeve 61 continues to move upwards, guided by the end face of the contact head 53, the upper end of the unlocking sleeve 61 pushes the contact head 53 gradually away from the lock sleeve along the radial direction. The contact head 53 drives the sliding rod 52 to slide away from the lock sleeve along the sliding channel of the fixing block 51 until the contact head 53 disengages from the limiting position of the insertion hole 41, completing the unlocking action. The lock sleeve can then be moved upwards and disassembled for easy operation. The end face profile of the contact head 53 can be conical, arc-shaped, or other convex profiles, as long as it ensures that the contact head 53 can smoothly slide into the insertion hole 41 after contacting the lock sleeve and smoothly disengage from the insertion hole 41 after contacting the unlocking sleeve 61. This also reduces wear on the connection structure between the lock sleeve, the second locking component 5, and the unlocking sleeve 61, extending the service life of the training head.

[0060] like Figure 3 and Figure 4 As shown, specifically in this embodiment, the lower port edge of the locking sleeve has a first ramp surface, and the upper port edge of the unlocking sleeve 61 has a second ramp surface. This configuration allows the contact head 53 to smoothly push open via the first ramp surface and slide into the insertion hole 41 during the locking action, completing the locking between the locking sleeve and the second locking component 5. During the unlocking action, the contact head 53 can gradually contact the side wall of the unlocking sleeve 61 via the second ramp surface, and smoothly disengage from the insertion hole 41 under the pressure of the unlocking sleeve 61, completing the unlocking between the locking sleeve and the second locking component 5. This reduces wear on the connection structure between the locking sleeve, the second locking component 5, and the unlocking sleeve 61, resulting in smoother movement and extending the service life of the teaching head.

[0061] Specifically, in this embodiment, the unlocking mechanism 6 further includes a driving component, which drives the unlocking sleeve 61 to extend or retract along the axial direction of the locking sleeve. The driving component can also be a cylinder or other driving device, as long as it can drive the unlocking sleeve 61 to extend or retract along the axial direction of the locking sleeve. This configuration facilitates the quick installation and removal of the head mold body 2 and the top component 3 via the unlocking sleeve 61, improving the flexibility of the training head.

[0062] like Figures 2-4 As shown, specifically in this embodiment, the driving component includes: a telescopic rod 62 and a driving mechanism 63. One end of the telescopic rod 62 is fixedly disposed on the base 1. The telescopic end of the telescopic rod 62 is connected to the lower end of the unlocking sleeve 61, and the telescopic direction of the telescopic rod 62 is collinear with the axial direction of the lock sleeve. The driving end of the driving mechanism 63 is drivenly connected to the telescopic end of the telescopic rod 62 and is used to drive the telescopic rod 62 to extend or retract. With this configuration, when it is necessary to unlock the top component 3 and the head mold body 2, the drive mechanism 63 drives the telescopic end of the telescopic rod 62 to rise, so that the unlocking sleeve 61 located at the telescopic end gradually approaches the second locking component 5 and completes the unlocking action; when it is necessary to lock the top component 3 and the head mold body 2, the operator gradually moves the locking sleeve closer to the unlocking sleeve 61 located at the telescopic end, while the drive mechanism 63 drives the telescopic end of the telescopic rod 62 to fall, so that the unlocking sleeve 61 located at the telescopic end gradually moves away from the second locking component 5, so that the second locking component 5 can smoothly extend into the insertion hole 41 of the locking sleeve and complete the locking action, which facilitates the installation and removal of the top component 3 and the head mold body 2.

[0063] Specifically, in this embodiment, the telescopic rod 62 includes a fixed rod 621 and a telescopic rod 622. The fixed rod 621 is fixedly connected to the base 1. The telescopic rod 622 is slidably sleeved with the end of the fixed rod 621 away from the base 1, and the end of the telescopic rod 622 away from the fixed rod 621 is connected to the lower end of the unlocking sleeve 61. The telescopic rod 622 is also drivenly connected to the drive mechanism 63. With this configuration, the telescopic rod 62 provides support force for the unlocking sleeve 61 during its telescopic movement, facilitating adjustment of the support height of the unlocking sleeve 61 in the telescopic direction of the telescopic rod 62, resulting in a compact connection structure and convenient operation.

[0064] Specifically, in this embodiment, the driving mechanism 63 includes: a toggle member 631, a linkage rod 632, a diagonal brace 633, and a second elastic member 634. The toggle member 631 has an extension end that can extend out of the side of the base 1 and a toggle end that can extend into the base 1, and the toggle member 631 is rotatably connected to the base 1; one end of the linkage rod 632 abuts against the toggle end of the toggle member 631, and the linkage rod 632 is rotatably connected to the base 1. The extension end of the toggle member 631 rotates out of the base 1 under the action of an external force; one end of the diagonal brace 633 is connected to the linkage rod... One end of 632 away from the actuating member 631 is movably connected, and the other end of the diagonal brace 633 is movably connected to the telescopic end of the telescopic member 62. The linkage rod 632 is used to push the end of the diagonal brace 633 movably connected to the linkage rod 632 closer to or away from the telescopic member 62. The diagonal brace 633 is used to push the telescopic end of the telescopic member 62 to extend or retract. The second elastic member 634 is connected to the linkage rod 632 and is used to apply a restoring force to the linkage rod 632, so that the end of the linkage rod 632 movably connected to the diagonal brace 633 moves away from the telescopic member 62.

[0065] In practical applications, when only one of each of the actuating element 631, linkage rod 632, and diagonal brace 633 is provided, one end of the second elastic element 634 is fixedly connected to the base 1, and the other end of the second elastic element 634 is connected to the linkage rod 632. The second elastic element 634 can be a tension spring. The operator rotates the protruding end of the actuating element 631 out of the base 1. During the rotation, the actuating end of the actuating element 631 gradually extends into the base 1 and moves one end of the linkage rod 632, causing the linkage rod 632 to rotate and drive the diagonal brace 633 located at the other end of the linkage rod 632 to gradually approach the telescopic rod 62 until the angle of inclination of the diagonal brace 633 relative to the base 1 approaches 90°. At this time, the second elastic element 634 is in a stretched state, completing the lifting of the support height of the telescopic end of the telescopic rod 62, i.e., located at... The unlocking sleeve 61 at the telescopic end moves upward along the telescopic direction to complete the unlocking action. When locking is required, the operator applies external force to the extended end of the actuating member 631, causing the extended end of the actuating member 631 to return to its initial position. Due to the restoring force of the second elastic member 634, the first elastic member in the stretched state can apply tension to the linkage rod 632, causing the linkage rod 632 to return to its original position. During this process, the rotation of the linkage rod 632 causes the diagonal brace 633 to gradually move away from the telescopic member 62, so that the angle of inclination of the diagonal brace 633 relative to the base 1 gradually becomes less than 90°, completing the reduction of the support height of the telescopic end of the telescopic member 62. That is, the unlocking sleeve 61 at the telescopic end moves downward along the telescopic direction to facilitate the locking action. The operation is simple and improves the flexibility of the teaching head.

[0066] like Figure 6As shown, in some embodiments, there are two of each of the actuating element 631, the linkage rod 632, and the diagonal brace 633. The two actuating elements 631, the two linkage rods 632, and the two diagonal braces 633 are symmetrically distributed relative to the extension and retraction direction of the telescopic rod 62. The two ends of the second elastic element 634 are respectively connected to the ends of the two linkage rods 632 near the actuating element 631. The second elastic element 634 can be a tension spring. With this setup, the operator rotates the extended ends of both actuating elements 631 out of the base 1. During rotation, the actuating ends of the two actuating elements 631 gradually extend into the base 1 and actuate one end of the corresponding linkage rod 632, causing the two linkage rods 632 to rotate synchronously. This drives the diagonal brace 633 located at the other end of the linkage rod 632 to gradually approach the telescopic rod 62 until the angle of inclination of the two diagonal braces 633 relative to the base 1 is close to 90°. At this point, the second elastic element 634 is in a stretched state, completing the lifting of the support height of the telescopic end of the telescopic rod 62. When locking is required, the operator applies external force to the extended ends of the two actuating elements 631 respectively, causing the actuating elements to rotate. When the extended end of component 631 returns to its initial position, due to the restoring force of the second elastic component 634, the second elastic component 634, which is in a stretched state, can apply a pulling force to the ends of the two linkage rods 632 that are close to the actuating component 631, causing the linkage rods 632 to reset. During this process, the rotation of the two linkage rods 632 causes the corresponding diagonal bracing rods 633 to gradually move away from the telescopic rod 62, so that the angle of inclination of the two diagonal bracing rods 633 relative to the base 1 gradually becomes less than 90°. At this time, a triangular support structure is formed between the two diagonal bracing rods 633 and the base 1, which completes the reduction of the support height of the telescopic end of the telescopic rod 62, ensuring the reliability and stability of the structure during the driving process.

[0067] In other embodiments, two actuating elements 631, two linkage rods 632, and two diagonal braces 633 are provided, and the two actuating elements 631, two linkage rods 632, and two diagonal braces 633 are symmetrically distributed relative to the extension and retraction direction of the telescopic rod 62. The two ends of the second elastic element 634 are respectively connected to the ends of the two linkage rods 632 near the diagonal braces 633. In this case, the second elastic element 634 is a compression spring. With this setup, the operator rotates the extended ends of both actuating elements 631 out of the base 1. During rotation, the actuating ends of the two actuating elements 631 gradually extend into the base 1 and actuate one end of the corresponding linkage rod 632, causing the two linkage rods 632 to rotate synchronously. This drives the diagonal brace 633 located at the other end of the linkage rod 632 to gradually approach the telescopic rod 62 until the angle of inclination of the two diagonal braces 633 relative to the base 1 is close to 90°. At this point, the second elastic element 634 is in a compressed state, completing the lifting of the support height of the telescopic end of the telescopic rod 62. When locking is required, the operator applies external force to the extended ends of the two actuating elements 631 respectively, causing... When the extended end of the actuating member 631 returns to its initial position, due to the restoring force of the second elastic member 634, the second elastic member 634, which is in a compressed state, can apply a pushing force that moves away from each other to the ends of the two linkage rods 632 near the diagonal brace 633. The linkage rods 632 return to their original position, and the rotation of the two linkage rods 632 causes the corresponding diagonal brace 633 to gradually move away from the telescopic member 62, so that the angle of inclination of the two diagonal brace 633 relative to the base 1 gradually becomes less than 90°. A triangular support structure is formed between the two diagonal brace 633 and the base 1, which completes the reduction of the support height of the telescopic end of the telescopic member 62, ensuring the reliability and stability of the structure during the driving process.

[0068] like Figure 5 and Figure 6 As shown, specifically, in this embodiment, the drive mechanism 63 further includes a wedge block 635, which is disposed on the base 1. The height of the side of the wedge block 635 near the telescopic rod 62 is greater than the height of the side of the wedge block 635 near the edge of the base 1. The wedge surface of the wedge block 635 is slidably connected to the end of the linkage rod 632 away from the actuating member 631. The wedge block 635 is used to raise or lower the height of the end of the diagonal brace 633 that is movably connected to the linkage rod 632.

[0069] During operation, in the unlocking process, the drive mechanism 63 needs to drive the support height of the telescopic rod 62 to rise. At this time, the end of the linkage rod 632 away from the actuating element 631 moves along the wedge surface of the wedge block 635 and gradually approaches the telescopic rod 62, increasing the height of the end of the linkage rod 632 away from the actuating element 631 relative to the base 1. This increases the support height of the diagonal brace 633 on the linkage rod 632, completing the raising of the telescopic end of the telescopic rod 62. In the locking process, the drive mechanism 63 needs to drive the support height of the telescopic rod 62 to fall. At this time, the end of the linkage rod 632 away from the actuating element 631 moves along the wedge surface of the wedge block 635. As the movement gradually moves away from the telescopic rod 62, the height of the end of the linkage rod 632 away from the actuating element 631 relative to the base 1 decreases. This reduces the support height of the diagonal brace 633 on the linkage rod 632, completing the descent of the telescopic end of the telescopic rod 62. This ensures that the drive structure can provide support through the wedge block 635 during the drive process. The wedge block 635 increases the lifting amplitude of the end of the diagonal brace 633 connected to the telescopic rod 62, thereby increasing the lifting stroke of the telescopic end of the telescopic rod 62. This makes the switching between the unlocking sleeve 61 between the unlocking and locking positions clearer, making the unlocking and locking actions more reliable and improving the reliability and stability of the drive structure.

[0070] like Figure 6 As shown, specifically, in this embodiment, the drive mechanism 63 further includes: an arc-shaped rail 636 and a limiting stop 637. The arc-shaped rail 636 is disposed on the base 1, and the arc-shaped trajectory of the arc-shaped rail 636 coincides with the end movement trajectory of the linkage rod 632. The arc-shaped rail 636 is used to support the linkage rod 632. The limiting stop 637 is disposed on the side of the wedge surface near the arc-shaped rail 636. The limiting stop 637 is used to limit the movement of one end of the diagonal brace 633 near the linkage rod 632 along the extension direction of the limiting stop 637. This design facilitates the limiting of the linkage rod 632 and the diagonal brace 633, allowing the end of the diagonal brace 633 closest to the linkage rod 632 to move along the extension direction of the limiting stop 637 without detaching from the wedge surface of the wedge block 635 during its movement on the wedge surface. This avoids the risk of structural detachment at the movable connection between the linkage rod 632 and the diagonal brace 633, reduces the swaying of the linkage rod 632 during rotation, and improves the structural reliability of the drive mechanism 63.

[0071] like Figure 2As shown, specifically in this embodiment, the head assembly 3 includes: a hair-supporting leather cover 31 and a head cover shell 32. The hair-supporting leather cover 31 has multiple positioning holes 311 spaced apart along its edge. The head cover shell 32 is detachably connected to the head mold body 2. A first locking component 4 is fixedly connected to the inner wall of the head cover shell 32. The hair-supporting leather cover 31 covers the head cover shell 32, and multiple positioning pins 321 are spaced apart along the outer edge of the head cover shell 32. Each positioning pin 321 corresponds to and engages with each positioning hole 311. This arrangement, through multiple positioning points distributed at the connection edge, ensures a uniform force distribution between the hair-supporting leather cover 31 and the head cover shell 32 at the connection edge, guaranteeing the structural reliability and stability of the head assembly 3.
