Description

Technical Field

[0001] This utility model belongs to the technical field of door and window hardware accessories, specifically relating to handle modules and door and window systems including them. Background Technology

[0002] In the existing door and lock production and sales system, doors and locks are usually manufactured as two separate components. While this production method ensures product diversity and flexibility to a certain extent, it brings a series of problems and challenges in practical application. Because doors and locks are shipped separately, consumers or decorators need to match and assemble them during installation. However, this process is not always smooth. Some people, lacking the corresponding professional skills or experience, may face problems with installation or proper assembly. This not only prolongs installation time but may also lead to decreased lock performance or even security hazards due to improper installation.

[0003] To address the aforementioned issues, a door and window system exists in the relevant technology. This system comprises a handle module and a door lock integration module. The door lock integration module includes a door body and a lock. At the factory, the lock is integrated and assembled onto the door body. Thus, during the assembly process after the door and window system is manufactured, installers only need to connect the handle module to the lock to complete the assembly. Specifically, the lock includes a lock cylinder, a handle seat, a lock rod, and an inner handle head. The lock cylinder is located in a mounting groove within the door body. The handle seat is fastened to the side wall of the door body and conceals the lock cylinder. The inner handle head is rotatably connected to the handle seat, and at least a portion of the inner handle head is located on the side of the handle seat away from the lock cylinder. The lock rod passes through the inner handle head, handle seat, and lock cylinder, and is connected to both the inner handle head and the lock cylinder. When the inner handle head rotates, it drives the lock rod to rotate. Under the drive of the lock rod, the lock cylinder can switch between an unlocked state and a locked state. The inner handle head is also provided with several second fastening holes. The handle module includes a handle body, functional components, and several fasteners. The handle body has a socket cavity and a receiving cavity. A connecting sleeve is formed inside the receiving cavity. The connecting sleeve is used for the first end of the lock rod to pass through. The functional components are located in the connecting sleeve and act on the first end of the lock rod. The receiving cavity has several first fastening holes, and several fasteners are correspondingly set in several first fastening holes. During the assembly process after leaving the factory, the handle body is fitted onto the inner handle head through the socket cavity, and the fasteners are tightened to connect the fasteners to the second fastening holes. In order to facilitate the modular installation between the handle module and the door lock integration module, several fasteners need to be correspondingly set in several first fastening holes at the factory (otherwise, during the assembly process after leaving the factory, the fasteners would need to be placed into the first fastening holes one by one, which is very inconvenient). In addition, in order to prevent the fasteners from falling out of the first fastening holes during transportation or installation, the first fastening holes also need to be closed to block the fasteners. The closing treatment of the first fastening holes is relatively complicated and reduces production efficiency. Utility Model Content

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a handle module and a door and window system including the same, so as to solve the problem that the first fastening hole of the handle module needs to be closed at the factory to prevent the fastener from falling off, which leads to a reduction in production efficiency.

[0005] The technical solution adopted by this utility model to solve its problem is: A handle module includes: a handle body having a receiving cavity with a first fastening hole; a fastener including a head and a rod connected to each other, the rod being disposed within the first fastening hole and used to connect with a second fastening hole of an inner handle head; a connecting seat detachably connected to the receiving cavity, the connecting seat having a mounting hole for a first end of a locking rod to pass through; the connecting seat having a first sidewall and a second sidewall, the second sidewall being further away from the first fastening hole than the first sidewall; the connecting seat having an operating hole extending from the second sidewall to the first sidewall; the operating hole and the first fastening hole being opposite to each other; the head being located between the operating hole and the first fastening hole; the operating hole or the first sidewall being able to block the head so that the rod is always located within the first fastening hole.

[0006] As an optional implementation, the first sidewall can abut against the head, and the first sidewall has a guide post protruding toward the first fastening hole, with the head located inside the guide post.

[0007] As an optional implementation, the guide post is provided with a guide hole, and the side wall of the guide post is provided with an installation notch communicating with the guide hole. The installation notch is used to guide the head into the guide hole.

[0008] As an optional implementation, the handle module further includes a functional component disposed within the receiving cavity. The functional component acts on the first end of the locking rod. The connecting seat is provided with a functional structure, and the functional structure and the functional component cooperate with each other.

[0009] As an optional implementation, the functional component includes a slider, and the functional structure includes a guide rail, with the slider slidably connected to the guide rail.

[0010] As an optional implementation, the handle body has a partition wall disposed within the cavity of the handle body to divide the cavity into a connecting cavity and a receiving cavity. The connecting cavity is used to fit the inner handle head, and the first fastening hole is disposed in the partition wall.

[0011] As an optional implementation, a snap-fit ​​structure is provided between the connecting seat and the receiving cavity, and the connecting seat is fixed in the receiving cavity by the snap-fit ​​structure.

[0012] As an optional implementation, one of the connecting seat and the receiving cavity is provided with a limiting block, and the other is provided with a limiting groove. The limiting block and the limiting groove are connected to limit the rotation of the connecting seat relative to the receiving cavity.

[0013] As an optional implementation, multiple first fastening holes, multiple operating holes and multiple fasteners are provided, with each of the multiple operating holes corresponding to one of the multiple first fastening holes, and each of the multiple fasteners corresponding to one of the multiple first fastening holes.

[0014] This utility model also provides a door and window system, including the handle module described above.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a handle module and a door / window system including it. Firstly, by setting a connecting seat, the operating hole on the connecting seat or the first sidewall blocks the head of the fastener, ensuring the rod remains within the first fastening hole. This prevents the fastener from falling off during transportation or installation, ensuring the stability of the connection between the handle module and the inner handle head. Furthermore, it eliminates the need for finishing the first fastening hole, simplifying the production process and improving efficiency. Secondly, the connecting seat is detachably connected to the receiving cavity. During installation and maintenance, the connecting seat can be easily disassembled and installed, facilitating operation and repair of the handle module. Moreover, because the connecting seat is detachable, in practical applications, different functional structures can be set only on the connecting seat according to different usage requirements, without redesigning the entire handle module. For example, when a specific lock control function needs to be added, only a new connecting seat with the corresponding circuitry or mechanical structure needs to be designed to replace the original connecting seat. This design avoids large-scale modifications to the entire handle module due to functional changes, significantly reducing design costs and development cycles. At the same time, it also improves the versatility and scalability of the product, enabling it to better meet the diverse needs of the market. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] Example 1 Please see Figures 1 to 5 This application provides a handle module, which includes a handle body 1, a fastener 2, and a connecting seat 3. The handle body 1 has a receiving cavity 13, and the receiving cavity 13 has a first fastening hole 14. The fastener 2 includes a head 21 and a rod 22 connected to each other. The rod 22 is disposed in the first fastening hole 14 and is used to connect with a second fastening hole of the inner handle head 521. The connecting seat 3 is detachably connected to the receiving cavity 13 and has a mounting hole 33 for... The first end of the locking rod passes through; the connecting seat 3 has a first side wall 31 and a second side wall 32, the second side wall 32 is further away from the first fastening hole 14 relative to the first side wall 31, the connecting seat 3 is provided with an operating hole 34 that extends from the second side wall 32 to the first side wall 31, the operating hole 34 and the first fastening hole 14 are opposite to each other, the head 21 is located between the operating hole 34 and the first fastening hole 14, the operating hole 34 or the first side wall 31 can block the head 21 so that the rod 22 is always located in the first fastening hole 14.

[0026] It is understood that in this embodiment, the operating hole 34 is used for the operation tool to pass through, and the operation tool can act on the head 21 of the fastener 2 so that the rod 22 of the fastener 2 is connected to the second fastening hole of the inner handle head 521. For example, the operation tool is a screwdriver or a hammer.

[0027] The handle module provided in this application embodiment has two aspects. First, by setting a connecting seat 3, the head 21 of the fastener 2 is blocked by the operating hole 34 or the first side wall 31 on the connecting seat 3, so that the rod 22 is always located in the first fastening hole 14. This prevents the fastener 2 from falling off during transportation or installation, ensuring the connection stability between the handle module and the inner handle head 521. Furthermore, it eliminates the need for closing the first fastening hole 14, simplifying the production process and improving production efficiency. Second, the connecting seat 3 is detachably connected to the receiving cavity 13. During installation and maintenance, the connecting seat 3 can be easily disassembled and installed, facilitating the operation and maintenance of the handle module. Moreover, since the connecting seat 3 is detachable, in practical applications, according to different usage requirements, only the corresponding functional structure 36 can be set on the connecting seat 3 without redesigning the entire handle module. For example, when a specific lock 52 control function needs to be added, only a new connecting seat 3 with the corresponding circuit or mechanical structure needs to be designed to replace the original connecting seat 3. This design approach avoids large-scale modifications to the entire handle module due to functional changes, significantly reducing design costs and development cycles. At the same time, it improves the product's versatility and scalability, better meeting diverse market demands.

[0028] In one embodiment, the fastener 2 is a screw or threaded rod, and the second fastening hole is a threaded hole.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the first sidewall 31 abuts against the head 21, and a guide post 35 protrudes from the first sidewall 31 toward the first fastening hole 14, with the head 21 located within the guide post 35. Thus, by having the first sidewall 31 abut against the head 21 and providing a guide post 35 protruding from the first sidewall 31 toward the first fastening hole 14, and placing the head 21 within the guide post 35, effective guidance for the movement of the head 21 is achieved. This design ensures that the head 21 maintains a stable and accurate path during movement, preventing the rod 22 from shifting or wobbling, and improving assembly accuracy and reliability.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the guide post 35 is provided with a guide hole 351, and the side wall of the guide post 35 is provided with an installation notch 352 communicating with the guide hole 351. The installation notch 352 is used to guide the head 21 into the guide hole 351. In this way, the installation notch 352, as a guiding structure, provides a clear and convenient path for the head 21 to smoothly enter the guide hole 351, enabling the operator to quickly and accurately guide the head 21 into the guide hole 351, effectively reducing the installation difficulty, saving installation time, and improving assembly efficiency.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the handle module further includes a functional component 4, which is disposed within the receiving cavity 13. The functional component 4 acts on the first end of the locking rod. The connecting seat 3 is provided with a functional structure 36, which cooperates with the functional component 4. This layout makes full use of the internal space of the receiving cavity 13, making the structure more compact and reasonable. At the same time, the functional structure 36 on the connecting seat 3 cooperates with the functional component 4 to form a complete and orderly working mechanism. This cooperative design ensures that the action of the functional component 4 on the first end of the locking rod can be effectively transmitted and accurately executed, thereby ensuring the stability and reliability of the handle module's control function of the locking rod. Furthermore, since the connecting seat 3 is detachable, in practical applications, according to different usage requirements, only the corresponding functional structure 36 can be set on the connecting seat 3 without redesigning the entire handle module.

[0032] In one embodiment, the functional component 4 includes a deadbolt structure, which further includes a sliding member 41 and a rotating member 42 connected by a transmission. The sliding member 41 is slidably disposed in the receiving cavity 13, and the rotating member 42 extends into the mounting hole 33 and acts on the first end of the locking rod. Driven by the sliding member 41, the rotating member 42 can rotate between the unlocked position and the locked position. When the rotating member 42 is in the unlocked position, the locking rod can rotate freely. When the rotating member 42 is in the locked position, the rotating member 42 is connected to the first end of the locking rod to restrict the rotation of the locking rod, thus providing a reliable deadbolt function for the door lock.

[0033] In one embodiment, the functional structure 36 includes a guide rail, to which the slider 41 is slidably connected. Thus, the guide rail provides the slider 41 with a clear movement trajectory and precise guidance, ensuring that the slider 41 maintains a stable and accurate direction of movement during operation, avoiding functional failure or component damage due to sliding deviation. The slider 41 slides along the guide rail, precisely reaching its predetermined position, thereby enabling coordinated operation with other components and ensuring the normal operation of the entire functional component 4 and even the entire handle module. This sliding connection method is simple in structure, easy to manufacture and install, and has high reliability and durability, effectively reducing production and maintenance costs.

[0034] like Figure 2 and Figure 3As shown, in one embodiment, the handle body 1 has a partition wall 11 disposed within the cavity of the handle body 1 to divide the cavity into a connecting cavity 12 and a receiving cavity 13. The connecting cavity 12 is used to fit the inner handle head 521, and a first fastening hole 14 is disposed in the partition wall 11. Thus, in a first aspect, the connecting cavity 12 is specifically designed to fit the inner handle head 521. This design provides a stable and precise connection foundation between the inner handle head 521 and the handle body 1. Through the fitting action of the connecting cavity 12, it can be ensured that the inner handle head 521 and the handle body 1 remain synchronized during movement, effectively transmitting operating force and making unlocking and locking actions smoother and more reliable. At the same time, this connection method also has a certain positioning and fixing function, reducing the relative shaking between components and improving the stability and durability of the entire handle module. Secondly, the receiving cavity 13 provides independent installation space for other components such as the functional component 4, allowing each component to be arranged in an orderly manner without interfering with each other. This partitioned design not only optimizes the internal space utilization of the handle body 1, but also facilitates subsequent assembly, maintenance, and repair, reducing production costs and maintenance difficulty. Thirdly, the partition wall 11, as a separating component connecting the connecting cavity 12 and the receiving cavity 13, has a certain structural strength and stability. By setting the first fastening hole 14 here, the partition wall 11 can be firmly connected to other related components by fasteners 2 (such as screws), further enhancing the overall structural strength of the handle body 1. At the same time, this arrangement also facilitates positioning and fixing during assembly, improving assembly efficiency and accuracy, and ensuring that the various components of the handle module can work closely together and perform their functions normally.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, a snap-fit ​​structure is provided between the connecting seat 3 and the receiving cavity 13, and the connecting seat 3 is fixed in the receiving cavity 13 by the snap-fit ​​structure; thus, the snap-fit ​​design greatly simplifies the installation process. Compared with traditional threaded connections, welding and other connection methods, the snap-fit ​​does not require additional tools and complicated operation steps.

[0036] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, both the connecting seat 3 and the receiving cavity 13 are provided with a first locking block 37 and a second locking block 131. The first locking block 37 engages with the second locking block 131 to fix the connecting seat 3 within the receiving cavity 13. Workers only need to align the first locking block 37 on the connecting seat 3 with the second locking block 131 on the receiving cavity 13 and press gently to complete the connection, greatly improving assembly efficiency and reducing production costs. Simultaneously, this connection method facilitates subsequent disassembly and maintenance. When it is necessary to inspect or replace components within the connecting seat 3 or the receiving cavity 13, only a certain external force needs to be applied to overcome the frictional force of the engagement, and the connecting seat 3 can be easily removed from the receiving cavity 13, which is convenient and quick.

[0037] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, one of the connecting seat 3 and the receiving cavity 13 is provided with a limiting block 38, and the other is provided with a limiting groove 132. The limiting block 38 and the limiting groove 132 are connected to limit the rotation of the connecting seat 3 relative to the receiving cavity 13. Thus, firstly, the sidewall of the limiting groove 132 forms a mechanical constraint on the limiting block 38, preventing the connecting seat 3 from rotating within the receiving cavity 13. This limiting method is direct and effective, capable of withstanding a certain amount of torque, ensuring that the connecting seat 3 does not rotate unnecessarily when subjected to external forces, thereby ensuring the normal operation of other components connected to the connecting seat 3. Secondly, the design of the limiting block 38 and the limiting groove 132 provides clear guidance and positioning for the assembly process. During assembly, workers can quickly and accurately install the connecting seat 3 into the receiving cavity 13 based on the relative positions of the limiting block 38 and the limiting groove 132, reducing trial and error and adjustment time during assembly, and improving assembly efficiency and quality.

[0038] In one embodiment, multiple first fastening holes 14, multiple operating holes 34 and multiple fasteners 2 are provided, with multiple operating holes 34 corresponding to multiple first fastening holes 14 one by one, and multiple fasteners 2 being provided in multiple first fastening holes 14 one by one.

[0039] like Figure 2 As shown, in one embodiment, the handle body 1 also includes a cover 15, which is detachably placed on the receiving cavity 13 to close the receiving cavity 13. When assembly is required, the cover 15 is opened and the fastener 2 is tightened. After the fastener 2 is tightened, the cover 15 is put back on the receiving cavity 13 to complete the assembly.

[0040] Example 2 This application also provides a door and window system, including a handle module as described in any of the embodiments in Embodiment 1.

[0041] like Figure 6 As shown, in one embodiment, the door and window system further includes a door lock integration module 5, which includes a door body 51 and a lock 52. At the factory, the lock 52 is integrated and assembled onto the door body 51. Thus, during the assembly process after the door and window system is manufactured, the installer only needs to connect the handle module to the lock 52 to complete the assembly. Specifically, the lock 52 includes a lock cylinder, a handle seat 522, a lock rod, and an inner handle head 521. The lock cylinder is disposed in the mounting groove of the door body 51. The handle seat 522 is fastened to the side wall of the door body 51 and covers the lock cylinder. The inner handle head 521 is rotatably connected to the handle seat 522, and at least a portion of the structure of the inner handle head 521 is located on the side of the handle seat 522 away from the lock cylinder. The lock rod passes through the inner handle seat 522. The handle head 521, handle base 522, and lock cylinder are connected to the inner handle head 521 and lock cylinder respectively. When the inner handle head 521 rotates, it drives the lock cylinder to rotate. Under the drive of the lock cylinder, the lock cylinder can switch between unlocked and locked states. The inner handle head 521 is provided with several second fastening holes. Thus, after connecting the handle body 1 to the inner handle head 521, the assembly of the door and window system is completed by tightening the fasteners 2 to connect them to the first fastening holes 14. This greatly simplifies the installation steps, reduces the complexity of installation, and makes the installation process faster and more convenient. Furthermore, since the integrated door lock structure is pre-assembled, installation only requires simple assembly or fixing work, thus reducing the professional skills required of the installers. Even users without professional experience can easily complete the installation, reducing performance degradation and safety hazards caused by improper installation.

[0042] In summary, the handle module and the door and window system including it disclosed in this utility model can bring at least the following beneficial technical effects: (1) By setting the connecting seat 3, the head 21 of the fastener 2 is blocked by the operating hole 34 or the first side wall 31 on the connecting seat 3, so that the rod 22 is always located in the first fastening hole 14. This can prevent the fastener 2 from falling off during transportation or installation, ensure the connection stability between the handle module and the inner handle head 521, and eliminate the need for closing the first fastening hole 14, simplifying the production process and improving production efficiency. (2) The connecting seat 3 is detachably connected to the receiving cavity 13. During installation and maintenance, the connecting seat 3 can be easily disassembled and installed, which facilitates the operation and maintenance of the handle module. (3) Since the connecting seat 3 is detachable, in practical applications, the corresponding functional structure 36 can be set only on the connecting seat 3 according to different usage requirements, without having to redesign the entire handle module, thus reducing design costs. (4) Placing the head 21 inside the guide post 35 effectively guides the movement of the head 21. This design ensures that the head 21 maintains a stable and accurate path during movement, avoids the rod 22 from shifting or shaking, and improves the accuracy and reliability of the assembly.

[0043] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
