Description

Technical Field

[0001] This utility model relates to the field of comb technology, specifically to a comb structure with retractable comb teeth. Background Technology

[0002] A comb is a tool for combing hair. As a personal care tool, its core functions are to comb hair, promote scalp blood circulation, and reduce hair loss. Moreover, combs with retractable teeth can have their teeth retracted, which reduces the space occupied by the comb, making it more convenient to carry and also makes it easier to clean the hair tangled on the comb.

[0003] Existing patent publication number CN222583861U discloses a comb with retractable teeth, including a housing, a comb tooth assembly, and several connecting rods. The housing has a main rod that can slide within the housing. The comb tooth assembly includes a base plate and comb teeth disposed on the base plate. The housing has through holes for the comb teeth to pass through. One end of each connecting rod is hinged to the main rod, and the other end is hinged to the base plate. When the main rod slides within the housing, it drives the connecting rod to move, thereby driving the comb tooth assembly to move, realizing the switching between the extended and retracted states of the comb teeth. This utility model, by adopting a telescopic structure of connecting rods, is not easily worn, is convenient to use, and has a long service life.

[0004] The above-mentioned solution has the following problems during implementation. The device uses the cooperation of the main rod and connecting rod to drive the comb teeth to extend and retract. However, the main rod is limited only by a semi-cylindrical locking block within the first or second locking part. When the device is used forcefully, the comb teeth may press against the base plate, causing the base plate to rotate the connecting rod, which in turn causes the main rod to slide. This can easily lead to the main rod moving the first and second locking parts, causing the semi-cylindrical locking block to disengage from them. Therefore, limiting the main rod by the semi-cylindrical locking block within the first or second locking part is not stable enough, resulting in unstable limiting of the comb teeth and affecting the device's usability, significantly reducing its practicality. To address this, we provide a comb structure with extendable comb teeth to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a comb structure with retractable comb teeth, which solves the problem that the existing technology, which uses a semi-cylindrical locking block to limit the movement within the first or second locking part, is not stable enough and easily affects the use of the device.

[0006] This utility model provides the following technical solution: a comb structure with retractable comb teeth, including a lower shell and an upper shell, the upper shell being snapped onto the top of the lower shell, and an installation sleeve being threaded onto one end of the lower shell and the upper shell. A base plate is installed inside the lower shell and the upper shell, and comb teeth are equidistantly installed on the top of the base plate. Through holes are equidistantly opened on the top of the upper shell, and the comb teeth are inserted into the through holes. A telescopic component for driving the comb teeth to extend and retract is provided at the bottom of the base plate, a limiting component for locking the telescopic component is provided on one side of the telescopic component, and an unlocking component for unlocking the limiting component is provided on one side of the bottom of the lower shell.

[0007] As a preferred embodiment of the above technical solution, guide plates are connected to both sides of the inner wall of the lower housing, and guide sleeves are connected to both ends of the bottom plate, with the guide sleeves slidably fitted onto the surface of the guide plates.

[0008] The above technical solution allows for the limitation of the base plate, enabling it to move longitudinally more effectively.

[0009] As a preferred embodiment of the above technical solution, the telescopic component includes a main rod, which is slidably installed at the bottom of the inner side of the lower housing. A movable groove is provided through the top of the main rod. A fixed rod is fixedly installed at the bottom of the inner side of the lower housing. The fixed rod is disposed in the movable groove. Connecting rods are hinged at equal intervals at both ends of the main rod. The top of each set of connecting rods is hinged to the bottom of the base plate. Each set of limiting components is disposed on one side of the inner side of the main rod.

[0010] The above technical solution can drive the base plate to move longitudinally, and the base plate will also drive the guide sleeve to slide along the guide plate. The base plate drives the comb body to move longitudinally to extend and retract, so that the comb body can be extended or retracted as needed, making it more convenient to use.

[0011] As a preferred embodiment of the above technical solution, a movable rod is installed on the top of the main rod near the mounting sleeve, a guide opening is provided on the inner wall of the upper housing near the mounting sleeve, the movable rod is slidably inserted into the guide opening, a slot is provided at the top of the movable rod, a button is slidably installed on the surface of the upper housing near the guide opening, a plug is connected to the bottom of the button, and the plug is inserted into the slot.

[0012] The above technical solution allows the push button to slide via the insert rod, which in turn drives the movable rod to slide, making operation more convenient.

[0013] As a preferred embodiment of the above technical solution, the limiting component includes a sliding groove, which is located on one side of the bottom end of the main rod. A spring is installed on the upper side of the sliding groove. A limiting rod is slidably installed at the opening of the sliding groove, and the top end of the limiting rod is connected to the spring. Two sets of limiting holes are provided on the bottom side of the lower housing near the limiting rod, and the limiting rod is inserted into the limiting holes.

[0014] The above technical solution enables the main rod to be locked in a more stable and secure manner. It is also not easy to unlock the device even with force, making it more convenient to use and greatly increasing its practicality.

[0015] As a preferred embodiment of the above technical solution, the unlocking component includes a limiting sleeve, which is installed on the bottom end of the lower housing near the limiting hole. A pressing plate is slidably installed inside the limiting sleeve, and a push rod is connected to the top of the pressing plate at the position corresponding to the two sets of limiting holes.

[0016] The above technical solution enables the pressing plate to drive two sets of push rods to be inserted into the limiting hole, so that the push rod pushes the limiting rod from the limiting hole into the slide groove to compress the spring, thus unlocking the main rod.

[0017] As a preferred embodiment of the above technical solution, the inner wall of the limiting sleeve is provided with two sliding grooves on both sides. A spring is installed on the upper side of each set of two sliding grooves, and a slider is slidably installed on the lower side of each set of two sliding grooves. The top of each set of sliders is connected to the spring, and the end of each set of sliders near the pressing plate is fixedly connected to the side end of the pressing plate.

[0018] The above technical solution allows the slider to be reset by the spring force of the second spring when the pressure plate is released and the pressure is lost. This allows the slider to drive the pressure plate, which in turn drives the push rod to reset, making the process more convenient.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention features a telescopic component that allows the base plate to move longitudinally, extending or retracting the comb body as needed, making it more convenient to use. A limiting component further securely locks the main rod, ensuring the comb body remains firmly in place even with force. Additionally, an unlocking component allows the locking of the main rod to be released, making operation even easier and significantly increasing the device's practicality.

Detailed Implementation

[0027] 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.

[0028] like Figures 1-5As shown, this utility model provides a technical solution: a comb structure with retractable comb teeth, including a lower shell 1 and an upper shell 2. The upper shell 2 is snapped onto the top of the lower shell 1. One end of the lower shell 1 and the upper shell 2 is screwed with an mounting sleeve 23. A base plate 3 is installed inside the lower shell 1 and the upper shell 2. Comb teeth 31 are equidistantly installed on the top of the base plate 3. Through holes 21 are equidistantly opened on the top of the upper shell 2. The comb teeth 31 are inserted into the through holes 21. Guide plates 12 are connected to both sides of the inner wall of the lower shell 1, and guide sleeves 3 are connected to both ends of the base plate 3. 2. The guide sleeve 32 is slidably fitted onto the surface of the guide plate 12, allowing the base plate 3 to be limited and enabling better longitudinal movement. The bottom end of the base plate 3 is provided with a telescopic assembly 4 for driving the comb body 31 to extend and retract. The telescopic assembly 4 includes a main rod 41, which is slidably installed inside the bottom end of the lower housing 1. A movable groove 43 is formed through the top end of the main rod 41. A fixed rod 11 is fixedly installed inside the bottom end of the lower housing 1, and the fixed rod 11 is located within the movable groove 43. Connecting rods 42 are hinged at equal intervals at both ends of the main rod 41. The top ends of the connecting rods 42 are all hinged to the bottom end of the base plate 3. Each set of limiting components 5 is located inside one side of the main rod 41. A movable rod 44 is installed on the top end of the main rod 41 near the mounting sleeve 23. A guide opening 22 is provided on the inner wall of the upper housing 2 near the mounting sleeve 23. The movable rod 44 is slidably inserted into the guide opening 22. A slot 45 is provided at the top end of the movable rod 44. A button 46 is slidably installed on the surface of the upper housing 2 near the guide opening 22. A plug rod 47 is connected to the bottom end of the button 46 and is inserted into the slot 45. This structure makes... By pressing and pulling the button 46, the button 46 drives the movable rod 44 to slide within the guide opening 22 via the insert rod 47. This allows the movable rod 44 to push and pull the main rod 41 to slide, causing the main rod 41 to drive the movable groove 43 to slide along the fixed rod 11. Then, the main rod 41 can push and pull several sets of connecting rods 42 to rotate, causing the connecting rods 42 to drive the base plate 3 to move longitudinally. The base plate 3 will also drive the guide sleeve 32 to slide along the guide plate 12. This allows the comb body 31 to be extended or retracted as needed, making it more convenient to use.

[0029] It should be noted that the installation method of several sets of connecting rods 42 is adopted in the comparative document. Each set of connecting rods 42 has connecting holes on both the upper and lower sides. Furthermore, several sets of rotating shafts are installed on the side end of the main rod 41 and the bottom end of the base plate 3. By aligning the connecting holes of the connecting rods 42 with the corresponding rotating shafts and inserting the rotating shafts into the connecting holes, the upper and lower sides of the connecting rods 42 can be fitted onto the corresponding rotating shafts, thereby completing the installation of the connecting rods 42 and realizing the hinge connection.

[0030] To further explain, by inserting the rod 47 into the slot 45 to snap the button 46 into place, forcefully moving the button 46 will cause the rod 47 to be pulled out of the slot 45, allowing the button 46 to be disassembled. Then, by rotating the mounting sleeve 23 and unscrewing it from one end of the lower housing 1 and the upper housing 2, the lower housing 1 and the upper housing 2 can be forcefully moved to separate them until disassembly is complete. This allows for more convenient inspection and maintenance of the interior of the lower housing 1 and the upper housing 2.

[0031] As one implementation method in this embodiment, such as Figure 2 and Figure 4 As shown, a limiting component 5 for locking the telescopic component 4 is provided on one side. The limiting component 5 includes a slide groove 51, which is opened on one side of the bottom end of the main rod 41. A spring 52 is installed on the upper side of the slide groove 51. A limiting rod 53 is slidably installed at the opening of the slide groove 51, and the top end of the limiting rod 53 is connected to the spring 52. Two sets of limiting holes 13 are opened on the bottom side of the lower housing 1 near the limiting rod 53. The limiting rod 53 is inserted into the limiting hole 13. This structure allows the main rod 41 to also drive the limiting rod 53 to move to correspond with the limiting hole 13. The limiting rod 53 is pushed into the limiting hole 13 by the spring force of the spring 52. In this way, the main rod 41 can be limited and locked, which is more stable and not easy to unlock even with force. It is more convenient to use and greatly increases the practicality of the device.

[0032] As one implementation method in this embodiment, such as Figure 4 and Figure 5As shown, an unlocking component 6 for unlocking the limiting component 5 is provided on one side of the bottom end of the lower housing 1. The unlocking component 6 includes a limiting sleeve 61, which is installed on the side of the bottom end of the lower housing 1 near the limiting hole 13. A pressing plate 62 is slidably installed inside the limiting sleeve 61. Push rods 63 are connected to the top of the pressing plate 62 at positions corresponding to the two sets of limiting holes 13. This structure allows the pressing plate 62 to drive the two sets of push rods 63 into the limiting holes 13, so that the push rods 63 push the limiting rod 53 from the limiting hole 13 into the slide groove 51 to compress the spring 52. In this way, the lock on the main rod 41 can be unlocked. Slide grooves are provided on both sides of the inner wall of the limiting sleeve 61. Each set of slide grooves 64 has a spring 65 installed on its upper side and a slider 66 slidably installed on its lower side. The top of each slider 66 is connected to the spring 65, and the end of each slider 66 near the pressing plate 62 is fixedly connected to the side end of the pressing plate 62. When the pressing plate 62 is pressed, the pressing plate 62 will also drive the slider 66 to slide and compress the spring 65 in the slide groove 64. When the pressing plate 62 is released and the pressure is lost, the spring force of the spring 65 can push the slider 66 to reset, so that the slider 66 can drive the pressing plate 62, and the pressing plate 62 can drive the push rod 63 to reset, which is more convenient.

[0033] Working principle: To extend the comb body 31 for use, first press the press plate 62 to drive the two sets of push rods 63 into the limiting hole 13. This push rod 63 pushes the limiting rod 53 from the limiting hole 13 into the slide groove 51 to compress the spring 52, thus unlocking the main rod 41. Then press and push the mating button 46, causing the button 46 to drive the movable rod 44 to slide in the guide opening 22 via the insert rod 47. This allows the movable rod 44 to push the main rod 41 to slide, causing the main rod 41 to drive the movable groove 43 to slide along the fixed rod 11. Then the main rod 41 can push several sets of connecting rods 42 to rotate, causing the several sets of connecting rods 42 to slowly rotate. Slowly lift the base plate 3 upwards. The base plate 3 will also drive the guide sleeve 32 to slide along the guide plate 12 until the base plate 3 drives the comb body 31 to pass through the through hole 21 and move to the outside of the lower housing 1 and the upper housing 2. In this way, the comb body 31 can be extended for use. At the same time, the main rod 41 will also drive the limiting rod 53 to move to correspond with a set of limiting holes 13 away from the mounting sleeve 23. The limiting rod 53 is pushed into the limiting hole 13 by the spring force of the spring 52. In this way, the main rod 41 can be limited and locked. It is more stable and not easy to unlock even with force. It is more convenient to use and greatly increases the practicality of the device.

[0034] To retract the comb body 31, simply press the pressing plate 62 to unlock the main rod 41, then press and pull back the engagement button 46. This causes the button 46 to slide the movable rod 44 within the guide opening 22 via the insert rod 47. The movable rod 44 then pulls the main rod 41, causing it to slide along the fixed rod 11 and the movable groove 43. The main rod 41 then pushes several sets of connecting rods 42 to rotate, slowly pulling the base plate 3 down. The base plate 3 also causes the guide sleeve 32 to slide along the guide plate 12 until the base plate 3 is pulled down. The movable comb body 31 retracts into the lower housing 1 and the upper housing 2. At the same time, the main rod 41 will also drive the limiting rod 53 to move to correspond with a set of limiting holes 13 near the mounting sleeve 23. The limiting rod 53 is pushed into the limiting hole 13 by the spring force of the spring 52, so that the main rod 41 can be limited and locked, and the comb body 31 can be retracted. This reduces the space occupied by the device and makes it easier to store. Moreover, when several sets of comb bodies 31 retract through the through hole 21, the hair wrapped around the comb body 31 can also be cleaned, making cleaning more convenient.

[0035] In addition, when the pressing plate 62 is pressed, the pressing plate 62 will also drive the slider 66 to slide and compress the spring 65 in the second groove 64. When the pressing plate 62 is released and the pressure is lost, the spring force of the second spring 65 can push the slider 66 to reset, so that the slider 66 can drive the pressing plate 62, and the pressing plate 62 can drive the push rod 63 to reset, which is more convenient and greatly increases the convenience of the device.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
