Description

Technical Field

[0001] This utility model relates to the field of door lock component technology, specifically to an ultra-narrow door lock handle component that facilitates reversing operation. Background Technology

[0002] In modern architectural design, especially for narrow-framed doors with limited space, traditional door lock handles often fail to meet usage needs due to their large size, inconvenient operation, or complex reversing mechanism. Traditional door lock handles are typically designed for one-way operation, meaning they can only be opened and closed from one side. This is particularly inconvenient in special applications, such as doors requiring operation from both sides, emergency exits, or situations where flexible adjustment of the opening direction is needed. Furthermore, traditional door locks have complex transmission mechanisms, high maintenance costs, and are difficult to install and replace in confined spaces.

[0003] Especially in the design of ultra-narrow door frames, the size and structural design of door lock components face greater challenges due to space constraints. Traditional door lock handles, often due to their complex structure and numerous components, are difficult to adapt to the installation requirements of ultra-narrow door frames, and also inconvenient for users to perform quick and convenient reversing operations. In addition, during long-term use, traditional door locks are prone to problems such as inflexible operation, jamming, or failure due to wear and aging, affecting the user experience and security performance. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-narrow door lock handle assembly that facilitates reversing operation, in order to solve the problem mentioned in the background art that traditional door lock handles are often difficult to adapt to the installation requirements of ultra-narrow door frames due to their complex structure and numerous components, and are also inconvenient for users to perform quick and convenient reversing operations.

[0005] To achieve the above objectives, this utility model provides an ultra-narrow door lock handle assembly that facilitates reversing operation, including a housing. A transmission assembly is installed in the middle of the inner side of the housing, a drive rod is installed at the bottom of the inner side of the housing, and a handle is installed in the middle of the outer side of the housing. The transmission assembly includes a back shell and a front cover. A push assembly is installed in the middle of the interior of the back shell. A pin is provided at the top of the push assembly. A first clutch and a second clutch are installed at the end of the handle near the interior of the back shell. The top of the pin passes through the second clutch and engages with the first clutch.

[0006] Preferably, a positioning plate is installed in the middle of the back shell, and a round hole is provided in the middle of the positioning plate, and the pin slides vertically with the round hole.

[0007] Preferably, a return spring is fitted on the outer wall of the pin.

[0008] Preferably, the pushing assembly includes a positioning shell, and a top rod is vertically slidably disposed inside the positioning shell. The bottom end of the top rod abuts against the top end of the push rod, and an arc-shaped plate is connected to the top of the top rod. The middle part of the arc-shaped plate abuts against a pin.

[0009] Preferably, the second clutch is rotatably connected to the face cover, and the first clutch is rotatably connected to the back cover.

[0010] Preferably, a tightening bolt is installed at the bottom of the housing, and the top of the tightening bolt tightens and fixes the bottom of the drive rod.

[0011] Preferably, the top end of the drive rod is engaged with the bottom end of the push rod.

[0012] Preferably, the back cover and the front cover are fixed together by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This ultra-narrow door lock handle assembly, designed for easy reversing, achieves a compact structure by installing a transmission component in the center of the inner casing, along with the design of the drive rod and handle. It is particularly suitable for ultra-narrow door frames with limited space. This assembly is not only small in size but also easy to operate, significantly improving the user experience.

[0015] Secondly, the ingenious cooperation between the push component and the latch in the transmission assembly, as well as the rotating connection design of the first and second clutch components, allows the handle to easily achieve reversible operation. Users can simply adjust the direction of the handle to change the opening and closing direction of the door lock, thus meeting the needs of dual-sided operation or flexible adjustment of the opening direction. This design not only improves the flexibility of the door lock but also enhances its practicality.

[0016] Furthermore, this invention ensures stable movement of the latch under the action of the pushing component by incorporating a return spring, and allows it to automatically reset after operation, thus improving the reliability and durability of the door lock. Simultaneously, the matching design of the positioning plate and the round hole, along with the fixing method of the tightening bolts, further guarantees the stability and security of the door lock assembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides an ultra-narrow door lock handle assembly that facilitates reversing operation, such as... Figures 1-3 As shown, the device includes a housing 1, a transmission assembly 2 mounted on the inner center of the housing 1, a drive rod 3 mounted on the inner bottom of the housing 1, and a handle 4 mounted on the outer center of the housing 1. The transmission assembly 2 includes a back shell 21 and a front cover 22. A push assembly 5 is mounted in the middle of the interior of the back shell 21, and a pin 6 is provided on the top of the push assembly 5. A first clutch 23 and a second clutch 24 are mounted near the interior of the back shell 21 at the end of the handle 4. The top of the pin 6 passes through the second clutch 24 and engages with the first clutch 23. This assembly, by mounting the transmission assembly 2 on the inner center of the housing 1 and cleverly connecting the drive rod 3 to the transmission assembly 2, combined with the handle 4 on the outer center of the housing 1, forms a compact and efficient transmission mechanism. This design not only makes the overall size of the door lock handle assembly small, making it particularly suitable for installation in ultra-narrow door frames, but also ensures convenient and smooth operation.

[0024] Secondly, the ingenious cooperation between the push component 5 and the latch 6 inside the transmission assembly 2, as well as the design of the first clutch 23 and the second clutch 24 at the end of the handle 4, together enable convenient reversing operation of the door lock handle. When the user needs to change the opening direction, they only need to adjust the direction of the handle 4, and the rotation of the first clutch 23 and the second clutch 24, along with the engagement of the latch 6 with the first clutch 23, easily achieves the door lock reversal. This design greatly improves the flexibility and practicality of the door lock, meeting the usage needs in different scenarios.

[0025] Furthermore, the design of the pin 6 passing through the second clutch 24 and engaging with the first clutch 23 not only ensures the stability of the transmission process but also enhances the security performance of the door lock. This engaging mechanism effectively prevents accidental unlocking or jamming during operation, thus ensuring reliable operation of the door lock and user safety.

[0026] In this embodiment, a positioning plate is installed in the middle of the back cover 21, and a round hole is provided in the middle of the positioning plate. The pin 6 slides vertically with the round hole. This design ensures that the pin 6 can slide stably and linearly under the action of the pushing component 5, thereby accurately engaging or disengaging with the first clutch component 23, improving the transmission accuracy and stability of the door lock handle assembly.

[0027] Specifically, a return spring 61 is fitted onto the outer wall of the latch 6. This allows the latch 6 to automatically spring back to its initial position after the pushing action is completed. This design not only enhances the automation level of the door lock handle assembly but also ensures that the assembly maintains stable transmission performance after repeated use, thus extending its service life.

[0028] Furthermore, the actuating component 5 includes a positioning shell 51. Inside the positioning shell 51, a push rod 52 is vertically slidably mounted. The bottom end of the push rod 52 abuts against the top end of the push rod 31. An arc-shaped plate 53 is connected to the top of the push rod 52, and the middle of the arc-shaped plate 53 abuts against the latch 6. The push rod 52 slides vertically under the push of the drive rod 3, and transmits the thrust to the latch 6 through the arc-shaped plate 53, thus realizing the opening and closing action of the door lock. This design makes the transmission process smoother, and the abutment between the arc-shaped plate 53 and the latch 6 reduces friction and wear during transmission, improving the durability of the component.

[0029] Furthermore, the second clutch 24 is rotatably connected to the face cover 22, and the first clutch 23 is rotatably connected to the back cover 21. This design allows users to easily change the direction of the door lock by simply adjusting the handle 4, greatly improving the flexibility and practicality of the door lock.

[0030] Furthermore, a tightening bolt is installed at the bottom of the housing 1, and the top of the tightening bolt secures the bottom of the drive rod 3. This design ensures that the drive rod 3 will not wobble or shift during transmission, thereby guaranteeing the stability and safety of the door lock handle assembly.

[0031] Furthermore, the top end of the drive rod 3 engages with the bottom end of the push rod 31, allowing them to connect tightly and work together to open and close the door lock. This design simplifies the assembly process, improves assembly efficiency, and ensures the stability and reliability of the transmission process.

[0032] Furthermore, the back cover 21 and the front cover 22 are fixed together by bolts. This ensures the integrity and stability of the transmission assembly 2. This design makes the door lock handle assembly less prone to loosening or deformation during long-term use, thus guaranteeing the reliability and durability of the door lock. At the same time, the bolt connection also facilitates the disassembly and maintenance of the assembly, reducing maintenance costs.

[0033] In use, the ultra-narrow door lock handle assembly of this utility model, which facilitates reversing operation, first applies force through the handle 4 located in the middle of the outer side of the outer shell 1 when the user needs to operate the door lock. The rotation of the handle 4 will cause the first clutch 23 and the second clutch 24 at its end to rotate relative to each other. Since the first clutch 23 is rotatably connected to the back shell 21 and the second clutch 24 is rotatably connected to the face cover 22, this rotation can be smoothly transmitted to the inside of the transmission assembly 2.

[0034] Inside the transmission assembly 2, the push assembly 5 plays a crucial role. When the user turns the handle 4, the push rod 52 in the push assembly 5 is pushed vertically by the drive rod 3 (via the push rod 31). The sliding of the push rod 52 causes the arc plate 53 at its top to move together, and the arc plate 53 then abuts against and pushes the latch 6.

[0035] After being pushed by the arc plate 53, the pin 6 will slide steadily and linearly along the circular hole in the middle of the positioning plate. This sliding process not only ensures that the pin 6 can accurately engage or disengage with the first clutch 23, but also, through the action of the return spring 61, allows the pin 6 to automatically spring back to the initial position after completing the pushing action, preparing for the next operation.

[0036] When the bolt 6 engages with the first clutch 23, the door lock is in the locked state; when the bolt 6 disengages from the first clutch 23, the door lock is in the unlocked state. Because the engagement between the bolt 6 and the first clutch 23 is secure and reliable, it effectively prevents accidental unlocking or jamming during operation, ensuring reliable operation of the door lock and user safety.

[0037] Furthermore, the tightening bolts at the bottom of the outer casing 1 firmly secure the bottom of the drive rod 3, ensuring that the drive rod 3 will not wobble or shift during transmission, thereby guaranteeing the stability and safety of the door lock handle assembly. Simultaneously, the back cover 21 and the front cover 22 are fixed together by bolts, ensuring the integrity and stability of the transmission assembly 2, making the door lock handle assembly less prone to loosening or deformation during long-term use.

[0038] When reversing is required, the tightening bolt is removed, causing the push rod 31 to descend, which in turn causes the push rod 52 of the push assembly 5 to descend, causing the pin 6 to descend, which in turn causes the first clutch 23 and the second clutch 24 to separate, thereby facilitating the reversing operation of the handle 4.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
