Description

Technical Field

[0001] This utility model belongs to the field of hair styling equipment technology, specifically relating to a locking comb. Background Technology

[0002] Existing hair dryers are typically one-piece designs, meaning each product usually only offers one styling function. When users need to achieve different styles such as straightening or curling, they need to purchase multiple different units, which is costly and inconvenient to store. Furthermore, if a component fails, the entire product often needs to be replaced, resulting in waste. Some manufacturers have introduced multi-functional styling tools with interchangeable attachments, allowing for diverse styling needs by connecting different accessories to a single main handle. However, existing interchangeable attachment styling tools often use simple plug-in or snap-fit ​​connections. These simple connections are prone to loosening under external force or after prolonged use, leading to unstable connections between accessories and the handle, affecting the user experience, and even posing safety hazards.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] See Figure 1-16 .

[0035] like Figure 1-3 As shown, this utility model provides a locking hair comb, including a handle 1 and an accessory 2. The accessory 2 is a styling device, such as a straightener or curler. The handle 1 is provided with an annular cavity 11. The accessory 2 includes a plug 21, which is inserted into the annular cavity 11. The handle 1 is provided with a self-locking device 3 for locking the plug 21. like Figure 4-7 As shown, the self-locking device 3 includes a rotating ring 31 rotatably connected to the handle 1, an elastic reset component 5 is provided between the rotating ring 31 and the handle 1, a guide block 311 is provided on the rotating ring 31, a connecting groove 12 and a mounting groove 13 are provided on the handle 1, and a pushing device 4 is provided on the plug 21. The pushing device 4 includes a pushing member 41, a positioning member 42 and a locking groove 43 provided between the pushing member 41 and the positioning member 42 and adapted to the guide block 311 and the pushing member 41. When using, such as Figure 8-10As shown, when it is necessary to lock accessory 2, the user inserts accessory 2 into the annular cavity 11. The plug 21 is inserted into the annular cavity 11, and the pushing member 41 contacts and pushes against the guide block 311. The guide block 311 slides into the connecting groove 12 under the pushing action of the pushing member 41 and moves along the connecting groove 12 away from the mounting groove 13. At this time, the elastic reset component 5 is stretched. When the pushing member 41 is fully inserted into the mounting groove 13, the locking groove 43 communicates with the connecting groove 12 and is on the same straight line. At this time, the pusher 41 is fully inserted into the connecting groove 12 and cannot push and limit the guide block 311. At this time, the stretched elastic reset component 5, under the elastic action, drives the rotating ring 31 to rotate and reset, and drives the guide block 311 to slide precisely from the connecting groove 12 into the locking groove 43. The accessory 2 is firmly locked and cannot be pulled out. Then, the plug 21 of the accessory 2 is directly aligned with and inserted into the annular cavity 11 of the handle 1. Push it all the way down and you will hear a crisp click. This means that it is installed in place and has been automatically locked. You can then turn on the comb for styling. When different types of accessories 2 need to be replaced to achieve different functional effects and shape requirements, hold the handle 1 and rotate the rotating ring 31 with the other hand, so that the guide block 311 rotates out from the locking groove 43 and reaches the connecting groove 12. At this time, the guide block 311 no longer jams the pusher 41, and the accessory 2 is smoothly withdrawn. At this time, the guide block 311 returns to the mounting groove 13 under the action of the elastic reset component 5.

[0036] Specifically, the locking groove 43 is parallel to or located on the same straight line as the extending direction of the connecting groove 12, so that the guide block 311 can slide smoothly from the connecting groove 12 into the mounting groove 13 without any obstruction.

[0037] It should be noted that when there is no external force, the rotating ring 31 and the guide block 311 are always in the default locked position, that is, the guide block 311 is located on the connecting groove 12 and abuts against the upper top surface of the handle 1.

[0038] Specifically, the mounting groove 13 and the connecting groove 12 are connected, the extension direction of the mounting groove 13 is perpendicular to the extension direction of the connecting groove 12, and the mounting groove 13 and the connecting groove 12 are T-shaped.

[0039] Specifically, such as Figure 5-10As shown, the pusher 41 is provided with a first inclined surface 411, and the guide block 311 is provided with a second inclined surface 3111 that is adapted to the first inclined surface 411. In use, the first inclined surface 411 of the pusher 41 first contacts the second inclined surface 3111 of the guide block 311. Through the sliding fit of the inclined surfaces, the axial thrust is efficiently converted into the circumferential radial force, which easily pushes the guide block 311 into the connecting groove 12, causing the rotating ring 31 to rotate and stretch the elastic member 51.

[0040] Compared with the existing technology that adopts an integral structure, this application realizes the adaptation of different accessories on a single handle 1 to achieve different shapes and functions, which not only meets various needs but also greatly reduces costs. Furthermore, when the accessory 2 or the handle 1 is damaged, only the damaged part needs to be replaced.

[0041] Meanwhile, this application employs a mechanical linkage locking mechanism consisting of a rotating ring 31, a guide block 311, an elastic reset component 5, and a pushing device 4 working together. The pushing force is converted into the circumferential force of the guide block 311, thereby enabling the rotating ring 31 to rotate. The elastic reset component 5 automatically resets the ring, locking the accessory 2 to the handle 1. The accessory 2 can be easily removed and replaced with a new part simply by rotating the rotating ring 31 to unlock it, making insertion and removal convenient and quick.

[0042] The jacking device 4 is provided in four sets, and the number of the jacking devices 4 is adapted to the number of the guide blocks 311.

[0043] Specifically, such as Figure 7 As shown, the elastic reset assembly 5 includes an elastic element 51, a connecting rod 52 disposed on the air guide 15, and a connecting rod 53 disposed on the rotating ring 31. One end of the elastic element 51 is sleeved on the connecting rod 52, and the other end is sleeved on the connecting rod 53. When the accessory 2 is not inserted, the elastic element 51 is in its natural state, and the guide block 311 is located on the mounting groove 13. When the accessory 2 is inserted, the guide block 311 is pushed and rotated into the connecting groove 12 by the inclined surface of the pusher 41. At this time, the elastic element 51 is in a stretched state. When the positioning member 42 is fully inserted... When the mounting slot 13 is engaged, the guide block 311 resets under the elastic action of the elastic element 51, causing the connecting rod 53 to rotate, which in turn causes the rotating ring 31 to rotate. The guide block 311 reaches the locking slot 43, locking the accessory 2 and the handle 1 together. When the accessory 2 needs to be removed, the user manually rotates the rotating ring 31, causing the guide block 311 to rotate into the connecting slot 12. At this time, the handle 1 and the accessory 2 are in an unlocked state. The elastic element 51 is stretched, allowing the accessory 2 to be removed and the rotating ring 31 to be released. The rotating ring 31 then automatically resets under the action of the elastic element 51 and rotates into the mounting slot 13. Preferably, such as Figure 11 As shown, the elastic reset assembly 5 is provided in two sets, which are symmetrically arranged along the axis of the handle 1. The two sets of elastic elements 51 serve as backups for each other. In extreme cases, even if one set of elastic elements 51 fails unexpectedly, the other set of elastic elements 51 can still provide sufficient return torque to pull the guide block 311 back to the locked position. This greatly increases the reliability and fault tolerance of the product and reduces the failure rate. At the same time, the two sets of symmetrical springs work simultaneously, and the forces they generate are equal in magnitude and opposite in direction. This avoids unilateral wear of the guide block 311 or locking groove 43 caused by unilateral force, and also ensures the coaxiality of the connection between the accessory 2 and the handle 1 after locking. There will be no slight skew or looseness, which improves the connection rigidity and quality. The rotating ring 31 is driven to rotate smoothly around the axis of the handle 1 without generating any lateral force that presses the rotating ring 31 to one side. This eliminates internal friction and interference, reduces noise, and makes the rotation and return of the rotating ring 31 exceptionally smooth and light, providing a good feel for the user during operation.

[0044] Preferably, the elastic element 51 is a spring.

[0045] Furthermore, such as Figure 12-13 As shown, the handle 1 includes a fixing ring 14 and an air guide 15 disposed within the fixing ring 14. The air guide 15 is fixedly connected to the fixing ring 14, and an annular cavity 11 is formed between the fixing ring 14 and the air guide 15. The connecting groove 12 and the mounting groove 13 are disposed on the fixing ring 14.

[0046] Furthermore, as shown in the figure, the air guide 15 is provided with an annular groove 152, the elastic reset component 5 is disposed in the annular groove 152, and the handle 1 is snapped with a housing 16, the housing 16 encloses the elastic reset component 5 to prevent the elastic reset component 5 from being disturbed by the outside.

[0047] like Figure 14 As shown, the fixing ring 14 is provided with an abutment 141. The abutment 141 is located at the edge of the mounting groove 13 away from the plug 21. The abutment 141 is used to limit the movement distance of the push member 41, preventing the push member 41 from being inserted too deeply, which would cause the connecting groove 12 and the locking groove 43 to be out of line. This makes it easy for the user to clearly know that it is in place without further observation or guessing whether it is inserted in place, providing a clear tactile feel for installation.

[0048] Preferably, such as Figure 15As shown, the handle 1 is provided with a plug-in mark 17, which includes an unlock mark 171 and a lock mark 172. The outer surface of the rotating ring 31 is provided with an indicator 312. The indicator 312 is aligned with the unlock mark 171 or the lock mark 172. In use, without applying any external force, the indicator 312 is aligned with the lock mark 172. When the accessory 2 is inserted into the handle 1, the indicator 312 gradually moves from the lock mark 172 to the unlock mark 171. When the accessory 2 is inserted into place and abuts against the abutment member 141, that is, when the locking groove 43 and the connecting groove 12 are on the same straight line, the indicator 312 is located at the unlock mark 171. Then, the guide block 311 returns to its original position under the action of the elastic member 51, and the indicator 312 immediately moves from the unlock mark 171 to the lock mark 172. At the same time, the connection status can be quickly understood according to the plug-in mark 17.

[0049] like Figure 16 As shown, in this embodiment, various accessories 2 with different functions can be inserted and locked to the handle 1 to achieve different multi-functional designs. This also facilitates replacement and unlocking, saving costs. The following is a detailed explanation of the working principle of this utility model; The user inserts the plug 21 of accessory 2 into the annular cavity 11 of handle 1. The inclined surface 411 at the front end of the pusher 41 first contacts the inclined surface 3111 of guide block 311. As insertion continues, the axial thrust is converted into circumferential force through the interaction of the inclined surfaces, pushing guide block 311 along the connecting groove 12, thereby causing the rotating ring 31 to rotate and stretching the elastic members 51 on both sides. At this time, the indicator 312 rotates from the locking mark 172 to the unlocking mark 171. When the plug 21 is fully inserted and the pusher 41 is fully in the mounting groove 13, and the positioning member 42 abuts against the abutment member 141, the locking groove 43 is aligned and connected with the connecting groove 12. At this time, the pusher 41 no longer obstructs the guide block 311, and the stretched elastic member 51 releases its elastic potential energy, pulling the connecting rod 53, driving the rotating ring 31 to rotate in the opposite direction, and causing the guide block 311 to slide precisely into the locking groove 43 of the pusher device 4, completing the locking. At this point, a "click" sound will be heard, and the indicator 312 will return to the locked position pointing to the locking mark 172. When it is necessary to replace accessory 2, the user holds handle 1 and rotates the rotating ring 31 with the other hand to overcome the spring force and make the guide block 311 rotate out of the locking groove 43 and back into the connecting groove 12. At this time, the guide block 311 releases its lock on the pusher 41, and accessory 2 can be pulled out. After releasing the rotating ring 31, the elastic element 51 will automatically return it to its initial position, with the guide block 311 located at the end of the mounting groove 13.

[0050] The innovation of this utility model lies in its ability to adapt and connect various accessories with different functions through a single handle body, meeting diverse user needs and avoiding the expense of purchasing multiple complete units, thus significantly reducing costs. If an accessory or handle is damaged, it can be replaced individually, reducing waste. Furthermore, simply aligning the accessory plug, inserting it, and pushing it all the way in will automatically lock it under the action of the elastic reset component; the process is simple and intuitive. Disassembly is quick and easy; simply rotating the rotating ring allows for easy removal of the accessory. The mechanical linkage locking mechanism, composed of a rotating ring, guide block, elastic reset component, and pushing device, cleverly converts axial thrust into circumferential rotational force using an inclined plane, and automatically locks it in place via a spring. This ensures structural stability, secure connection, and safe operation.
