Description

Technical Field

[0001] This utility model relates to the field of lock structures and safety gate railings, and in particular to a child safety gate railing locking structure and a child safety gate railing using the same. Background Technology

[0002] Child safety gates are often used at interior doorways, stairwells, kitchen entrances, and other locations to prevent children from entering areas where accidents could easily occur.

[0003] Existing child safety gate rails generally include two posts at both ends and a safety gate set between the two posts. The safety gate is made of several metal strips, plastic strips, wooden strips, mesh or cloth, etc. One end of the safety gate can be connected to the post at one end through a connector, and the other end of the safety gate is locked to the post at the other end through a locking structure such as a lock or buckle to lock or unlock.

[0004] The existing locking structure has the following problems: the locking is unreliable, the door guardrail is prone to being partially ajar, children can easily open the door guardrail, which can easily lead to safety problems and make it difficult to safely protect children. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art by providing a child safety gate railing locking structure. It adopts an upper and lower overlapping locking structure (specifically, by upper and lower suction), which is convenient for lifting up to separate the overlapping and unlock the safety gate, and also convenient for the lock seat and lock body to automatically overlap and lock when the safety gate is lowered, so as to realize convenient and quick unlocking and safe and reliable locking, thereby improving the reliability of the child safety gate railing and protecting children's safety.

[0006] The above-mentioned technical objectives of this utility model are mainly achieved through the following technical solutions:

[0007] The technical solution of the first technical subject of this utility model is: a child safety gate railing locking structure, including a lock base and a lock body that cooperates with the lock base for locking or unlocking. The lock base and the lock body overlap, and a locking structure is provided at the overlapping part of the lock base and lock body. The upper overlapping part of the lock body is located above the lower overlapping part of the lock base and can overlap. When an external force is applied to the lock body causing it to move upward, the locking structure unlocks. When the lock body loses the external force and is under its own weight, the lock body overlaps the lock base, and the locking structure locks. This changes the existing technology's method of horizontal insertion or horizontal suction to form a lock, adopting a locking structure of upper and lower overlap locking (specifically, unlocking or locking through upper and lower suction locking). This facilitates both lifting the overlap to separate and unlock the safety gate, and automatically overlapping the lock base and lock body to form a lock when the safety gate is lowered. This achieves convenient and quick unlocking and safe and reliable locking, thereby improving the reliability of the child safety gate railing and protecting children's safety. Meanwhile, by adopting an overlapping and suction method, the lock body and lock seat are locked together by suction, which reduces the need for springs (used to push the bolt to move laterally) in existing technologies. This further simplifies the structure and helps reduce production, assembly, and maintenance costs.

[0008] As a further improvement and supplement to the above technical solution, this utility model adopts the following technical measures: A safety structure is provided on the lock base or the lock body. When the safety structure is unlocked, the lock body can move upwards under external force to unlock. When the lock body and the lock base are locked, the safety structure is locked to prevent the lock base from accidentally moving upwards to unlock. The purpose of the safety structure is to ensure reliable locking, forming a safety barrier and preventing the lock body from being accidentally lifted and unlocked. This further improves the locking reliability of the child safety gate railing locking structure during use.

[0009] Preferably, the safety structure is disposed on the lock seat, and the safety part on the safety structure is engaged with the lock body. When the safety structure is locked, the safety part is pushed out and pressed against the lock body to achieve the safety locking of the safety structure; when the safety part is pushed back to its original position, the safety structure is unlocked.

[0010] Preferably, the locking structure includes an upper magnet disposed below the upper overlapping portion and a lower magnet disposed above the lower overlapping portion, wherein the upper and lower magnets are magnetically attracted and locked together. The upper and lower magnets can be magnetic objects with magnetic attraction force, such as magnets or electromagnets.

[0011] Preferably, the lock base is provided with an indicator component, which is linked to the lower magnet. When the upper and lower magnets are attracted, the lower magnet and the indicator component move upward, indicating that the lock body is in the locked state. When the upper and lower magnets separate, the indicator component and the lower magnet move downward under the influence of gravity, indicating that the lock body is in the unlocked state. The purpose of the indicator component is to allow users to easily observe the status of the locking structure (whether it is in the unlocked or locked state). Especially in the locked state, it is necessary to ensure that the lock is fully engaged and avoid any false locking, thereby ensuring the reliable locking of the child safety gate railing locking structure during use and ultimately ensuring child safety.

[0012] Preferably, the indicating component includes an indicating block, a receiving cavity is provided in the lower overlapping portion, an indicating window is provided on the side wall of the lower overlapping portion, the indicating block is disposed in the receiving cavity, a lower magnet is disposed inside the indicating block, and the indicating block has an unlocking indicator and a locking indicator arranged from top to bottom. One of the unlocking indicator and the locking indicator can cooperate with the indicating window, displaying either the unlocking indicator or the locking indicator through the indicating window. Normally, the outer side of the locking indicator is green, easily visible through the indicating window, thus confirming that the locking structure is in the locked position, helping to avoid the locking structure from being loosely locked. Similarly, the outer side of the unlocking indicator is red, easily visible through the indicating window, indicating that the locking structure is in the unlocked state. When unlocking, the lower magnet loses its upward attraction, and the indicating block falls with the lower magnet. The bottom of the indicating block rests on the bottom of the receiving cavity, and the unlocking indicator above the indicating block cooperates with the indicating window, with the red display surface of the unlocking indicator showing from inside the indicating window, thus indicating that it is in the unlocked state. Similarly, when the upper and lower magnets are attracted and locked, the lower magnet moves upward under the force of attraction, and the indicator block moves upward with the lower magnet. At this time, the locking indicator and the indicator window cooperate, and the green display surface on the locking indicator is displayed from inside the indicator window, so as to indicate that it is in the locked state.

[0013] The technical solution of the second technical subject of this utility model is as follows: a child safety gate guardrail, including a guardrail outer frame and a safety gate disposed within the guardrail outer frame. The guardrail outer frame includes a first post and a second post spaced apart. The first end of the upper rail of the safety gate is provided with the aforementioned lock body. The upper end of the first post is provided with the aforementioned lock seat. The second end of the upper rail is connected to the upper end of the second post via an upper rotating assembly, allowing the safety gate to swing up and down around the upper rotating assembly as a fulcrum. Lifting the lock body upwards unlocks the gate, while lowering it downwards locks it. The lock body and lock seat in this technical solution constitute the aforementioned child safety gate guardrail locking structure. The structure, working principle, and function of the lock body and lock seat are the same as those involved in the technical solution of the first technical subject.

[0014] Preferably, the outer frame of the guardrail also includes a crossbar connected at both ends to the lower ends of the first and second posts, respectively. The lower rail of the safety gate cooperates with the crossbar. A one-way stop is provided between the first end of the lower rail and the first end of the crossbar, and a lower rotating assembly is provided between the second end of the lower rail and the second end of the crossbar. The safety gate swings up and down with the upper and lower rotating assemblies as rotation fulcrums. The one-way stop limits the upward lifting range of the safety gate, which helps ensure the stable and normal operation of other joints on the safety gate (including the upper and lower rotating assemblies), thereby helping to ensure that the child safety gate guardrail can stably perform its safety protection function.

[0015] Preferably, the upper rotating assembly includes an upper rotating seat disposed at the upper end of the second column and an upper rotating body disposed at the second end of the upper column. The upper rotating seat has a rotating cavity at its upper part, located at one end facing the safety door. The rotating cavity has a downwardly inclined surface facing the safety door and a shaft hole penetrating the downwardly inclined surface. The upper rotating body has an extended lug extending towards the upper rotating seat, which overlaps the upper rotating seat. Below the extended lug, an upwardly inclined surface and a connecting post are disposed. The connecting post extends downward from the middle of the upwardly inclined surface and is inserted into the shaft hole. The upwardly inclined surface extends into the rotating cavity and engages with the downwardly inclined surface. The connecting post ensures that the upper rotating assembly can be stably assembled and can swing up and down within a certain range. The engagement of the upwardly and downwardly inclined surfaces facilitates smooth and accurate descent and reset, thereby improving locking reliability.

[0016] Preferably, a fixing clip is provided on the door frame of the security door, and the lock body is inserted into the door frame from top to bottom. The side wall of the lock body is engaged and clamped with the fixing clip. The fixing clip has a buckle, which forms a snap-fit ​​with the side wall of the lock body. The fixing clip facilitates convenient and quick installation of the lock body, reduces the number of screw holes on the security door, improves the strength and surface flatness of the security door, and prevents snagging during use (such as scratching skin or clothing). This further improves the comfort and reliability of the security door.

[0017] The beneficial effects of this utility model are as follows: 1. The locking structure, which uses an upper and lower overlapping locking mechanism (specifically, an upper and lower magnetic attraction), facilitates both lifting and unlocking the safety door, and automatically engaging the lock seat and lock body when the safety door is lowered, achieving convenient and quick unlocking and reliable locking. This improves the reliability of the child safety gate and protects children's safety. 2. The safety mechanism ensures the safety door is reliably locked, further enhancing the reliability of the child safety gate and ensuring its safety function. 3. The indicator component allows for direct observation of its status, preventing the locking structure from becoming loose and further ensuring the reliability of the locking structure during use. 4. The upper rotating component has a reasonable structure that ensures smooth lifting and accurate lowering and locking of the safety door, making the child safety gate easy to open and reliably locked. 5. The fixed buckle design facilitates quick and easy installation of the lock body, reduces the number of screw (bolt) holes on the security door, improves the strength and surface flatness of the security door, and prevents snagging during use (such as scratching skin or clothing), further enhancing the comfort and reliability of the security door.

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] Example 1: The technical solution of the first technical subject involved in this utility model: a child safety gate railing locking structure, including a lock seat 1 and a lock body 2 that cooperates with the lock seat 1 for locking or unlocking.

[0026] The difference between this technical solution and the prior art is that: the lock base 1 and the lock body 2 overlap, and the overlapping part of the lock base 1 and the lock body 2 is provided with a locking structure. The upper overlapping part 3 of the lock body 2 is located above the lower overlapping part 4 of the lock base 1 and can overlap. When the lock body 2 is subjected to an external force and moves upward, the locking structure unlocks. The lock body 2 loses the external force and, under its own weight, overlaps the lock base 1, and the locking structure locks.

[0027] Instead of using the existing horizontal insertion or suction locking method to form a lock, this technical solution adopts an upper and lower overlapping locking structure (specifically, unlocking or locking is achieved through upper and lower suction locking). This structure facilitates both lifting the overlapping part to unlock and open the safety door 14, and automatically engaging the lock seat 1 and lock body 2 when the safety door 14 is lowered. This achieves convenient and quick unlocking and safe and reliable locking, thereby improving the reliability of child safety gate railings and protecting children's safety.

[0028] Meanwhile, by adopting an overlapping and suction method, the lock body 2 and the lock seat 1 are locked together by suction, which reduces the need for springs (used to push the bolt to move laterally) in the existing technology, thereby further simplifying the structure and reducing production, assembly and maintenance costs.

[0029] In practical applications, the lock base 1 or the lock body 2 is provided with a safety structure 5. When the safety structure 5 is unlocked, the lock body 2 can move upward under the action of external force to unlock. When the lock body 2 and the lock base 1 are locked, the safety structure 5 is locked to prevent the lock base 1 from accidentally moving upward to unlock.

[0030] In this technical solution, the purpose of setting up the safety structure 5 is to ensure reliable locking, form a safety effect on the lock, and prevent the lock body 2 from being accidentally lifted and unlocked, which is conducive to further improving the locking reliability of the child safety gate railing locking structure during use.

[0031] Specifically, in practical applications, the safety structure 5 is mounted on the lock base 1, and the safety part 6 on the safety structure 5 is engaged with the lock body 2. When the safety structure 5 is locked, the safety part 6 is pushed out and pressed against the lock body 2 to lock the safety structure 5; when the safety part 6 is pushed back to its original position, the safety structure 5 is unlocked.

[0032] Of course, in practical applications, this safety structure 5 can also achieve the purpose of this utility model: the safety structure 5 includes a sliding groove with an upward opening and a small opening and a large cavity provided on the lock seat 1 or the lock body 2, a first spring placed in the sliding groove, a slider cooperating with the first spring, and a safety part 6 provided at the front end of the slider; when the slider is pushed out, the safety part 6 forms a safety lock with the lock body 2 or the lock seat 1, so that the lock body 2 and the lock seat 1 are in a reliable locked state.

[0033] Specifically, a safety insertion interface is provided on the lock base 1 or the lock body 2, and the safety part 6 is inserted into the safety insertion interface. When the slider is pushed out, the safety part 6 is inserted into the safety insertion interface, thereby locking the safety structure 5. When the slider is reset, the safety part 6 is retracted, thereby unlocking the safety structure 5.

[0034] In other words, in practical applications, the technical solution of lateral withdrawal to form a plug-in safety effect also falls within the protection scope of this utility model.

[0035] In practical applications, an indicator component is provided on the lock base 1. The indicator component is linked with the lower magnet 8. When the upper magnet 7 and the lower magnet 8 are attracted, the lower magnet 8 and the indicator component move upward, and the indicator component indicates that the lock body 2 is in the locked state. When the upper magnet 7 and the lower magnet 8 are separated, the indicator component and the lower magnet 8 move downward under the action of gravity, and the indicator component indicates that the lock body 2 is in the unlocked state.

[0036] In this technical solution, the purpose of setting the indicator component is to facilitate users to observe the status of the locking structure (whether it is in the unlocked or locked state) in a timely manner. In particular, for the locked state, it is necessary to ensure that the lock is in place and to avoid the occurrence of false locks. This helps to ensure the reliable locking of the child safety gate railing locking structure during use, and thus helps to ensure the safety of children.

[0037] In practical applications, the indicator component includes an indicator block 9, a receiving cavity 10 is provided in the lower overlapping part 4, an indicator window 11 is provided on the side wall of the lower overlapping part 4, the indicator block 9 is provided in the receiving cavity 10, the lower magnet 8 is provided inside the indicator block 9, and the indicator block 9 has an unlocking indicator 12 and a locking indicator 13 arranged from top to bottom. The unlocking indicator 12 and the locking indicator 13 can be selected to cooperate with the indicator window 11, and the unlocking indicator 12 or the locking indicator 13 can be displayed through the indicator window 11.

[0038] In this technical solution, the outer side of the locking indicator 13 is normally green, and the color can be easily seen through the indicator window 11, thus confirming that the locking structure is in the locked position, which helps to avoid the locking structure from being loosely locked. Similarly, the outer side of the unlocking indicator 12 is red, and the color can be easily seen through the indicator window 11, indicating that the locking structure is in the unlocked position.

[0039] Specifically, when unlocking, the lower magnet loses its upward attraction, and the indicator block 9 falls down along with the lower magnet. The bottom of the indicator block 9 rests on the bottom of the receiving cavity 10. The unlocking indicator 12 above the indicator block 9 cooperates with the indicator window 11, and the red display surface on the unlocking indicator 12 is displayed from inside the indicator window 11, thus indicating that it is in the unlocked state.

[0040] Similarly, when the upper and lower magnets are attracted and locked, the lower magnet moves upward under the force of attraction, and the indicator block 9 moves upward along with the lower magnet. At this time, the locking indicator 13 cooperates with the indicator window 11, and the green display surface on the locking indicator 13 is displayed from inside the indicator window 11, so as to indicate that it is in the locked state.

[0041] Example 2: Technical solution of the second technical subject involved in this utility model: a child safety gate guardrail, including a guardrail outer frame and a safety gate 14 set in the guardrail outer frame.

[0042] The difference between this technical solution and the prior art is that: the outer frame of the guardrail includes a first post 15 and a second post 16 spaced apart; the first end of the upper rail 17 on the safety gate 14 is provided with the lock body 2 as described in Embodiment 1; the upper end of the first post 15 is provided with the lock seat 1 as described in Embodiment 1; the second end of the upper rail 17 is connected to the upper end of the second post 16 through an upper rotating assembly 18, so that the safety gate 14 swings up and down with the upper rotating assembly 18 as the fulcrum; the lock body 2 is lifted and swings upward to unlock; the lock body 2 is lowered and swings downward to lock.

[0043] In this technical solution, the lock body 2 and lock base 1 constitute the aforementioned child safety gate railing locking structure. The structure, working principle, and function of the lock body 2 and lock base 1 are the same as those involved in the technical solution of the first technical subject.

[0044] In practical applications, the outer frame of the guardrail also includes a horizontal bar 19 with its two ends connected to the lower ends of the first post 15 and the second post 16, respectively. The lower rail of the safety gate 14 cooperates with the horizontal bar 19. A one-way stop 20 is provided between the first end of the lower rail and the first end of the horizontal bar 19. A lower rotating component 21 is provided between the second end of the lower rail and the second end of the horizontal bar 19. The safety gate 14 swings up and down with the upper rotating component 18 and the lower rotating component 21 as the rotation fulcrum.

[0045] In this technical solution, the one-way stop 20 is used to limit the upward lifting range of the safety gate 14, which helps to ensure that other joints on the safety gate 14 (including the upper rotating assembly 18 and the lower rotating assembly 21) can operate stably and normally, thereby helping to ensure that the child safety gate guardrail can stably play its safety protection role.

[0046] In practical applications, the upper rotating assembly 18 includes an upper rotating seat 22 disposed at the upper end of the second column 16 and an upper rotating body 23 disposed at the second end of the upper rail 17. The upper rotating seat 22 has a rotating cavity 24 at its upper part, and the rotating cavity 24 is located at one end facing the safety door 14. The rotating cavity 24 has a downward inclined surface 25 facing the safety door 14 and a shaft hole 26 penetrating the downward inclined surface 25 vertically. The upper rotating body 23 has an extension ear 27 extending towards the upper rotating seat 22. The extension ear 27 overlaps the upper rotating seat 22. An upper inclined surface 28 and a connecting post 29 are disposed below the extension ear 27. The connecting post 29 extends downward from the middle of the upper inclined surface 28 and is inserted into the shaft hole 26. The upper inclined surface 28 extends into the rotating cavity 24 and cooperates with the downward inclined surface 25.

[0047] In this technical solution, the connecting column 29 helps ensure that the upper rotating assembly 18 can be stably assembled together and can swing up and down within a certain range. The cooperation between the upper inclined surface 28 and the lower inclined surface 25 facilitates smooth and accurate descent and reset, thereby improving locking reliability.

[0048] In practical applications, in order to improve the overall viewing effect and reduce raw material consumption, a groove is often provided on the upper rotating seat 22 corresponding to the rotating cavity 24, and the outer ear 27 is placed in the groove.

[0049] In practical applications, a fixing clip 30 is provided on the door frame 32 of the security door 14, and the lock body 2 is inserted into the door frame 32 from top to bottom. The side wall of the lock body 2 is fastened and clamped with the fixing clip 30. The fixing clip 30 is provided with a buckle 31, and the buckle 31 is fastened and clamped with the side wall of the lock body 2.

[0050] In this technical solution, the side wall of the lock body 2 facing the lock seat 1 cooperates with the fixing clip 30 to clamp the door frame 32, so that the lock body 2 is stably fixed on the door frame 32.

[0051] Furthermore, to improve user comfort, the outer shell of lock body 2 is designed in an ergonomic shape, making it easy for users to grip and also serving as a handle. Appropriate materials are selected to enhance the grip feel.

[0052] In this technical solution, the setting of the fixed buckle 30 facilitates the convenient and quick installation of the lock body 2, while reducing the number of screw (bolt) holes on the safety door 14, which helps to improve the strength and surface flatness of the safety door 14, prevents the occurrence of hooking and scraping phenomena during use (such as scratching skin, clothing, etc.), and further improves the comfort and reliability of the safety door 14.

[0053] Further explanation of Embodiments 1 and 2: When the lock body 2 and lock seat 1 are swapped and reversed, they also fall within the protection scope of this utility model. That is, the lock body 2 is set on the outer frame of the guardrail (commonly known as the door frame 32), and the lock seat 1 is set on the safety door 14. With a suitable orientation, lifting the lock seat 1 can unlock it, and directional lock seat 1 can lock it.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
