Description

Technical Field

[0001] The utility model belongs to the technical field of door handles, in particular to a safety door handle device. Background Art

[0002] Door handles, a crucial component of doors in everyday life and many workplaces, are a common tool for opening and closing doors. Widely used in residential, commercial, and public facilities, they provide convenient entry and exit, ensuring accessibility and safety.

[0003] However, in the prior art, traditional door handles often rely solely on a handle connected to a door lock mechanism to achieve their basic opening and closing functions, while ignoring the safety needs of some special scenarios and groups of people. For example, for children or people who require special protection, existing door handles are too convenient to open and lack effective safety restrictions. For example, in a home environment, children may easily open the door and go out alone due to curiosity or a desire to explore the surrounding environment, which poses safety risks such as getting lost or encountering accidents. In some nursing institutions or special living places, people who need protection may also open the door on their own without supervision, leading to possible dangerous situations.

DETAILED DESCRIPTION

[0042] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-7 :

[0043] Example 1:

[0044] This embodiment provides a safety door handle device, comprising a first handle body 1 provided on a door panel and a second handle body 2 connected to the first handle body 1, and is characterized in that it further comprises:

[0045] The auxiliary handle mechanism 3 is provided in the second handle body 2;

[0046] The elastic door stop mechanism 4 includes a connecting block 40 sleeved on the first handle body 1 and the second handle body 2, a stop post 41 with one end provided on the connecting block 40 and the other end extending in the direction of the door panel opening end, an opening 42 provided at the bottom of the connecting block 40, and reinforcement components 43 provided on both sides of the opening 42;

[0047] The limiting mechanism 5 includes a limiting mounting plate 50 provided on the side of the first handle body 1 away from the opening end of the door panel, a limiting clamping hand 51 rotatably connected to the upper and lower sides of the limiting mounting plate 50, a pressing assembly 52 provided on the limiting clamping hand 51, and a locking assembly 53 provided in the limiting mounting plate 50, and the second handle body 2 is located between the limiting clamping hands 51.

[0048] One end of the first handle 1 and the internal structure of the door lock can be perpendicular to the door panel, and the second handle 2 can be connected to the other end of the first handle 1 by bolts, screws or other means, and the second handle 2 can be perpendicular to the first handle 1.

[0049] The auxiliary handle mechanism 3 is used to provide an additional holding method, so as to facilitate children, people in wheelchairs or other users to open the door more easily under special circumstances, thereby increasing the flexibility and adaptability of the door handle.

[0050] The elastic door stop mechanism 4 acts as a barrier when the door is open, preventing the door from being over-opened or accidentally closed, making it convenient for people to enter and exit, while also keeping the door open, making it easier to carry items and other operations, thereby improving the convenience and safety of door use.

[0051] The connecting block 40 connects the stop post 41 to the first and second handle bodies 1, 2, and provides a mounting location for the reinforcement assembly 43, ensuring the stability and integrity of the entire elastic door stop mechanism 4. Sleeved over the handle bodies, the connecting block 40 moves with the opening and closing of the door, allowing the elastic door stop mechanism 4 to closely coordinate with the movement of the door. The connecting block 40 is typically annular or partially annular, allowing it to fit tightly over the first and second handle bodies 1, 2. An opening 42 is provided at its bottom. The connecting block 40 can be made of rubber, silicone, or other elastic material. The opening 42 is enlarged to allow the first and second handle bodies 1, 2 to fit within the connecting block 40.

[0052] When the door is opened, the stopper 41's function is to hold one end against the doorframe or other objects, preventing the door from opening too far or closing unexpectedly. This prevents the door from opening too close or closing unexpectedly, thereby keeping the door open and facilitating entry and exit, as well as operations such as moving items. It absorbs the force of the door's opening and transmits it to the connecting block 40 and the handle, playing a key role in stabilizing the door's position. The stopper 41 is typically a columnar structure, and its length should be sufficient to effectively support the doorframe or other objects when the door is opened to the desired angle. The stopper 41 can be connected to the connecting block 40 by integral molding, bonding, or other means.

[0053] The function of the reinforcement component 43 is to enhance the structural strength and stability of the opening 42 of the connecting block 40. Because during the frequent opening and closing of the door, the opening 42 may be subjected to greater stress and deformation, causing the connecting block 40 to break and be damaged at the opening 42. Therefore, the reinforcement component 43 is used to ensure the long-term reliable use of the elastic door stop mechanism 4.

[0054] The limiting mechanism 5 limits and locks the second handle body 2 to prevent the door handle from loosening, shaking or accidentally unlocking during use, ensuring the normal use and safety of the door, especially playing a key role in preventing children or special groups from accidentally opening the door.

[0055] The position-limiting mounting plate 50 serves as a mounting platform for components such as the position-limiting latch 51, the pressing assembly 52, and the locking assembly 53. It connects and supports these components, enabling them to work together to limit and lock the second handle 2. The position-limiting mounting plate 50 also participates in the transmission process, transferring the force applied by the pressing assembly 52 to the position-limiting latch 51 and the locking assembly 53. The position-limiting mounting plate 50 is generally a plate-like structure and can be connected to the door panel by welding, bolts, or other means.

[0056] The limit latch 51 cooperates with the pressing assembly 52 and the locking assembly 53 to limit and unlock the second handle 2. When locked, the limit latch 51 firmly holds the second handle 2, preventing it from rotating and thus preventing the door from accidentally opening. When the door needs to be opened, the limit latch 51 is unlocked by operating the pressing assembly 52, and the second handle 2 returns to a rotatable state. The limit latch 51 is typically a plate-like structure with a certain curvature or curve. It is connected to the limit mounting plate 50 via a rotating shaft, hinge, or other rotatable connection method, allowing the limit latch 51 to open and close flexibly.

[0057] The pressing assembly 52 is used to receive user commands and convert the user's pressing actions into unlocking and locking actions of the limit mechanism 5. The operation of the pressing assembly 52 drives the transmission rod 522 to move, thereby locking and unlocking the limit latch 51 and the second handle 2. It is a key component for realizing manual control of the limit mechanism 5.

[0058] The locking assembly 53 cooperates with the pressing assembly 52 and the limiting latch 51 to lock and unlock the second handle 2. When the pressing assembly 52 is actuated, the locking assembly 53 cooperates with the transmission rod 522 to lock or unlock the limiting latch 51, thereby controlling the rotatability of the second handle 2 and ensuring safe use of the door.

[0059] Example 2:

[0060] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] The second handle 2 is a detachable structure, and the second handle 2 is formed by connecting two symmetrical halves.

[0062] The second handle 2 is the component that the user directly grasps and operates to open and close the door. It is connected to the first handle 1 to complete the door operation function. The second handle 2 is designed to be detachable to facilitate the installation of the auxiliary handle mechanism 3. The connection between the two halves can be achieved by snap-fitting, threading, bonding, or other suitable connection methods to ensure the firmness and stability of the connection and facilitate assembly and disassembly.

[0063] Example 3:

[0064] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] The auxiliary handle mechanism 3 includes:

[0066] The first pressing rod 30 is provided in the second handle body 2 and is close to the side of the door opening end. The second handle body 2 is provided with a first card slot, and the first pressing rod 30 is provided with a first card seat 31 that matches the first card slot.

[0067] The storage tube 32 is provided in the second handle body 2 and on a side away from the open end of the door panel. The second handle body 2 is provided with an opening 42 matching the storage tube 32, and an auxiliary handle assembly 320 is provided in the storage tube 32;

[0068] The connecting rod 33 is provided between the first pressing rod 30 and the storage tube 32 , and a first elastic return member 34 is sleeved on the connecting rod 33 . The first elastic return member 34 is located in the slot and is connected to the first pressing rod 30 and the first slot respectively.

[0069] The first pressing rod 30 is the operating trigger component of the auxiliary handle mechanism 3. The extension function of the auxiliary handle assembly 320 is activated by pressing the first pressing rod 30. It plays the role of transmitting the user's operating force in the second handle body 2, converting the user's pressing action into the movement of subsequent components, thereby realizing the use of the auxiliary handle. The first pressing rod 30 is usually a rod-shaped structure to facilitate the user's pressing operation. The first pressing rod 30 is connected to the first card slot in the second handle body 2 through the first card seat 31. This connection method not only ensures the relative fixation of the first pressing rod 30 in the second handle body 2, but also enables it to move within a certain range when pressed, realizing linkage with other components. The first card seat 31 and the first card slot can ensure the stability of the connection without causing difficulty in operation due to being too tight or shaking due to being too loose.

[0070] The storage tube 32 is used to house the auxiliary handle assembly 320, providing a storage space for the auxiliary handle assembly 320 when the auxiliary handle is not in use. The storage tube 32 is generally a tubular structure located within the second handle body 2. An opening 42 is provided on the side of the second handle body 2 away from the door panel opening to facilitate the entry and exit of the auxiliary handle assembly 320. The storage tube 32 can be mated with the opening 42 in the second handle body 2 and may be connected using some form of snap-fit, threaded connection, or other fastening method to ensure that the storage tube 32 is securely and stably installed within the second handle body 2.

[0071] The connecting rod 33 connects the first pressing rod 30 and the storage tube 32, transmitting the movement of the first pressing rod 30 to the storage tube 32, thereby realizing the linkage function of the auxiliary handle mechanism 3. When the user presses the first pressing rod 30, the connecting rod 33 can drive the auxiliary handle assembly 320 within the storage tube 32 to move, causing the auxiliary handle to extend or retract from the storage tube 32, realizing the use and storage functions of the auxiliary handle. The connecting rod 33 is typically a rod or strip structure and can be connected to the storage tube 32 and the first pressing rod 30 by welding, screwing, or other fixing methods.

[0072] The first elastic return member 34 provides an automatic reset function for the auxiliary handle mechanism 3. When the user presses the first pressing rod 30 to extend the auxiliary handle assembly 320 and then releases the first pressing rod 30, the first elastic return member 34 generates a restoring force, returning the first pressing rod 30, the connecting rod 33, and the storage tube 32 to their initial positions. Simultaneously, it causes the auxiliary handle assembly 320 to retract into the storage tube 32, automatically stowing the auxiliary handle and preparing it for the next use. The first elastic return member 34 is typically a spring, an elastic rubber sheet, or other elastic member, and can be connected to the first pressing rod 30 and the slot via a hook, a slot, welding, or other means.

[0073] Example 4:

[0074] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] The auxiliary handle assembly 320 includes:

[0076] A connecting rope 3200, one end of which is connected to the side of the storage tube 32 close to the opening end of the door panel;

[0077] The third handle 3201 is provided at the other end of the connecting rope 3200 and is located below the second handle 2 when in operation;

[0078] The tube cap 3202 is disposed on the third handle body 3201 and is threadedly connected to the opening 42 on the second handle body 2 .

[0079] The connecting cord 3200 connects the components within the storage tube 32 to the third handle 3201, enabling force transmission. When the auxiliary handle mechanism 3 is in operation, the connecting cord 3200 transmits the movement of the storage tube 32 to the third handle 3201, allowing the third handle 3201 to be pulled out of or retracted from the storage tube 32, thereby meeting the user's needs in different situations. The connecting cord 3200 is typically a slender, rope-like structure, with both ends connected to the third handle 3201 and the bottom of the storage tube 32 by knotting, riveting, welding, or other means, ensuring a secure and reliable connection between the connecting cord 3200, the storage tube 32, and the third handle 3201.

[0080] The third handle 3201 provides the user with an additional grip point, making it easier to open the door in difficult situations. When the auxiliary handle mechanism 3 is in operation, the user can grasp the third handle 3201 to assist in opening the door, increasing convenience and stability. This is particularly important for children, people in wheelchairs, and other users with special needs. The third handle 3201 is generally cylindrical, rod-shaped, or has a curved shape. The third handle 3201 is connected to the storage tube 32 via a connecting rope 3200.

[0081] Cap 3202 is primarily used to secure the third handle body 3201 within the storage tube 32 when the auxiliary handle is not in use. It protects the internal structure and aesthetically pleasing the handle. It prevents dust and debris from entering the storage tube 32 and potentially affecting the proper functioning of the auxiliary handle mechanism 3. Cap 3202 can be secured to the third handle body 3201 by welding, bolts, or other means. Opening 42 of cap 3202 is externally threaded, facilitating threaded connection to opening 42 of the third handle body 3201.

[0082] Example 5:

[0083] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0084] The reinforcement assembly 43 includes:

[0085] The connecting platform 430 is provided at the bottom of the connecting block 40 and located on one side of the opening 42;

[0086] The connecting bar 431 is disposed at the bottom of the connecting block 40 and located on the other side of the opening 42 . The connecting bar 431 is provided with a connecting hole 432 that matches the connecting platform 430 .

[0087] The connecting platform 430 is used to cooperate with the connecting strip 431 to enhance the structural strength of the bottom opening 42 of the connecting block 40. During the door opening and closing process, the connecting block 40 is subjected to certain stresses and forces, and in particular, the opening 42 is prone to deformation or damage. By connecting with the connecting strip 431, the connecting platform 430 can effectively disperse the stress, improve the overall stability and reliability of the connecting block 40, and ensure the proper operation of the elastic door stop mechanism 4. The connecting platform 430 is typically a block-shaped or boss-like structure and can be fixed to the bottom of the connecting block 40, located on one side of the opening 42, by integral molding with the connecting block 40 or other means.

[0088] The function of the connecting strip 431, together with the connecting platform 430, is to enhance the structural strength of the bottom opening 42 of the connecting block 40. By connecting to the connecting platform 430, the connecting strip 431 can connect the structures on both sides of the opening 42 together to form a single unit, effectively dispersing stress and preventing the connecting block 40 from deforming or damaging at the opening 42 due to uneven force, thereby ensuring the stability and reliability of the elastic door stop mechanism 4 during long-term use. The connecting strip 431 is typically a long strip structure, its length sufficient to span the bottom opening 42 of the connecting block 40 and mate with the connecting platform 430. The connecting strip 431 is provided with a connecting hole 432 that mates with the connecting platform 430 to ensure that the two can be accurately connected. The connecting strip 431 can be fixed to the bottom of the connecting block 40, located on the other side of the opening 42, by integral molding or other means.

[0089] Example 6:

[0090] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0091] The pressing assembly 52 includes:

[0092] The pressing groove 520 is provided on the limit clamp 51 and extends into the limit mounting plate 50;

[0093] The second pressing rod 521 is disposed in the pressing groove 520, and the bottom of the second pressing rod 521 is provided with a limiting hole that passes through both sides and communicates with the limiting mounting plate 50;

[0094] The transmission rod 522 is disposed at the bottom of the second pressing rod 521 , and a second locking seat 523 is disposed at the bottom of the transmission rod 522 .

[0095] The pressing groove 520 provides space for the installation and movement of the second pressing rod 521. When a user presses the pressing assembly 52 on the limit latch 51, the second pressing rod 521 can move up and down within the pressing groove 520, thereby converting the user's pressing action into a subsequent transmission action to control the locking and unlocking of the limit mechanism 5. The pressing groove 520 is typically a groove structure formed on the limit latch 51 and extending into the limit mounting plate 50.

[0096] The second pressing rod 521 is used to transmit the user's pressing action to the transmission rod 522, thereby achieving the locking and unlocking operation of the limit mechanism 5. When the user presses the second pressing rod 521, it moves downward within the pressing groove 520, transmitting the pressing force to the locking assembly 53 through the transmission rod 522. The second pressing rod 521 is generally a rod-shaped structure that matches the pressing groove 520. The second pressing rod 521 is installed in the pressing groove 520, and the two can adopt a clearance fit or other appropriate connection method to ensure that the second pressing rod 521 can move freely up and down within the pressing groove 520 without excessive shaking or deviation.

[0097] The transmission rod 522 is used to transmit the movement of the second pressing rod 521 to the locking assembly 53, thereby realizing the locking and unlocking functions of the limiting mechanism 5. When the second pressing rod 521 moves downward, the transmission rod 522 will move with the movement of the second pressing rod 521 and transmit the pressing force to the locking assembly 53, so that the locking assembly 53 cooperates with the limiting clamp 51 to limit the second handle body 2 between the limiting clamp 51, thereby realizing the locking of the door. The transmission rod 522 is generally a rod-shaped structure and can be fixed to the bottom of the second pressing rod 521 by welding, screwing or other means to ensure that it will not loosen or fall off when the force is transmitted. A second clamping seat 523 is provided at the bottom of the transmission rod 522. The second clamping seat 523 is used to cooperate with the second clamping slot at the top of the locking assembly 53 to prevent the transmission rod 522 from disengaging from the second clamping slot, allowing it to move back and forth stably in the second clamping slot.

[0098] Example 7:

[0099] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0100] The locking assembly 53 includes:

[0101] The locking groove 530 is provided below the pressing groove 520 , and a second latching groove is provided on the top of the locking groove 530 to cooperate with the second latching seat 523 ;

[0102] The second elastic reset member 531 is provided between the bottom of the transmission rod 522 and the bottom of the locking groove 530;

[0103] The limiting rod 532 is inserted into the limiting hole.

[0104] The locking groove 530 is designed to engage with the second retaining member 523 at the bottom of the transmission rod 522, providing space for the installation of the second elastic return member 531 and movement of the transmission rod 522. When the pressing assembly 52 is pressed, the force transmitted by the transmission rod 522 is received to lock the stopper 51, thereby restricting the rotation of the second handle 2 and preventing the door from being accidentally opened. Simultaneously, during the unlocking process, the locking groove 530 cooperates with the transmission rod 522 and the second elastic return member 531 to restore the door to its original state, allowing the stopper mechanism 5 to be reused. The locking groove 530 is located below the pressing groove 520 and at the center of the stopper mounting plate 50. A second retaining groove is provided at its top to engage with the second retaining member 523 at the bottom of the transmission rod 522. The locking groove 530 may be connected to the stopper mounting plate 50 through integral molding, welding, or other reliable fixed connection methods to ensure its fixed position on the stopper mounting plate 50 and prevent it from loosening or shifting during use, thereby affecting the normal operation of the stopper mechanism 5.

[0105] The second elastic reset member 531 is used to compress or stretch the second elastic reset member 531 when the pressing assembly 52 is pressed to perform a locking operation, storing elastic potential energy. When unlocking is required, the second elastic reset member 531 releases the elastic potential energy, providing a restoring force for the transmission rod 522 and related components, returning them to their initial position. This allows the limiter 51 to unlock the second handle 2 and restore the door to its openable state. This ensures the automatic reset function of the limit mechanism 5, making operation more convenient and reliable. The second elastic reset member 531 is commonly in the form of a spring, such as a coil spring, a disc spring, or an elastic rubber block. One end of the second elastic reset member 531 can be connected to the bottom of the locking groove 530 by hooking, gluing, or other means, and the other end contacts the bottom of the transmission rod 522.

[0106] The limiting rod 532 is mainly used to limit the movement of the second pressing rod 521, ensuring that when the second pressing rod 521 is pressed, the limiting hole on the second pressing rod 521 corresponds to the limiting mounting plate 50, thereby limiting the movement of the second pressing rod 521 and making the limiting handle 51 in a locked state, so that the second handle cannot open or close the door.

[0107] Example 8:

[0108] This embodiment provides a safety door handle device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0109] The connecting block 40 is made of natural rubber.

[0110] If the connecting block 40 is made of natural rubber, it can effectively buffer these impact forces. For example, when the door is opened quickly and the stopper 41 collides with the door frame, the connecting block 40 can absorb some of the impact force, preventing it from being directly transmitted to the door and door frame structure. This reduces damage to the door and door frame caused by long-term impact and extends their service life. Furthermore, natural rubber has a high coefficient of friction, which creates sufficient friction between the connecting block 40 and the first handle body 1 and the second handle body 2, preventing slippage. This ensures the stability of the elastic door stop mechanism 4 and allows the connecting block 40 to rotate with the second handle body 2.

[0111] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
