Description

Technical Field

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

[0002] In the field of door and window systems, the design of the sliding door locking structure and door mechanism has a significant impact on the safety, aesthetics, and ease of use of doors and windows. Currently, Chinese patent CN119664183A discloses a sliding door locking structure and door mechanism, which mainly consists of an upper track, a door body, a handle, and a sliding door locking structure. The sliding door locking structure includes components such as a lock box, a vertical frame, and a locking rod. The lock box is located on the upper track, the handle is mounted on the door body, the vertical frame is located on the vertical side wall of the door body, and the locking rod is connected to the handle. One end of the locking rod has a latch. Driven by the handle, the locking rod can move up and down, thereby causing the latch to extend into or disengage from the lock groove in the lock box, achieving locking and unlocking of the door. This design places the lock box and lock groove on the upper side of the door body, successfully removing them from the user's view and effectively improving the aesthetics of the door and window system.

[0003] The handle structure in this patent includes a sliding side plate, two actuating blocks, and two handle seats. The actuating blocks are used by the user to grip and operate the lock / unlock mechanism. The two actuating blocks are respectively mounted on the two handle seats. The sliding side plate has a transmission arm that extends into the gap between the door body and the handle seat, forming a transmission connection with the actuating blocks. Driven by the actuating blocks, the sliding side plate moves up and down vertically. The locking rod is connected to the sliding side plate and moves up and down synchronously with it, thereby realizing the locking and unlocking functions of the door lock.

[0004] However, in practical applications, this handle structure has some shortcomings. To avoid damaging the door structure (e.g., glass doors), the two handle bases are usually glued to both sides of the door. However, due to variations in door thickness, the final installation position of the two handle bases makes the connection between the drive arm and the actuating block difficult. This connection difficulty can not only affect the normal operation of the door lock and reduce its reliability, but also cause inconvenience during installation, increasing installation time and cost, thus failing to adequately meet actual usage needs.

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example 1 Please see Figures 1 to 5 This application provides a handle assembly, which includes a handle shell 1, a fixed shell 3, a sliding side plate 4, and two actuating blocks 2. The handle shell 1 includes a connecting shell 11 and two oppositely arranged handle seats 12, which are respectively distributed on both sides of the door body 200. The connecting shell 11 is fixedly connected between the two handle seats 12. The two actuating blocks 2 are correspondingly arranged on the two handle seats 12. The fixed shell 3 is fixed to the door body vertical frame 5, and the fixed shell 3 and the connecting shell 11 are fixedly connected. The sliding side plate 4 is slidably connected to the fixed shell 3 in the vertical direction, and is used for transmission connection with the lock rod 8. The sliding side plate 4 is fixedly provided with two transmission arms 41, which are correspondingly transmission connected to the two actuating blocks 2. Under the drive of the actuating blocks 2, the transmission arms 41 slide up and down so that the sliding side plate 4 drives the lock rod 8 to move up and down synchronously.

[0027] According to an embodiment of this application, a handle assembly, when installed on a door 200, allows the fixed housing 3 and the sliding side plate 4 to be connected, and both the fixed housing 3 and the connecting housing 11 to be fixed in relative positions to the door vertical frame 5. This forms a single unit comprising the fixed housing 3, handle housing 1, sliding side plate 4, and door vertical frame 5. Finally, the door vertical frame 5 is connected to the door 200. This installation method is unaffected by differences in the thickness of the door 200, eliminating the need to adjust the adhesive position of the handle base 12 to account for the thickness of the door 200, as is required in existing technologies. This greatly simplifies the installation process and improves installation efficiency. Furthermore, since the fixed shell 3, handle shell 1, sliding side plate 4, and door frame 5 form a stable overall structure, the installation position of the handle seat 12 relative to the transmission arm 41 will not be affected by factors such as adhesive and the thickness of the door 200. This ensures that the transmission arm 41 and the actuating block 2 can always maintain a stable transmission connection, ensuring that the power can be accurately and stably transmitted to the lock rod 8 when operating the handle, thereby realizing reliable locking and unlocking of the door lock and improving the safety and stability of the door lock.

[0028] In one embodiment, a first cavity for accommodating the door body 200 is formed between the two handle bases 12, and a second cavity for accommodating the door body 200 is formed between the two transmission arms 41.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a guide block 32 is provided on the fixed shell 3, and a guide groove 43 is provided on the sliding side plate 4. The guide groove 43 and the guide block 32 are slidably connected to provide guidance for the vertical movement of the sliding side plate 4 relative to the fixed shell 3. Thus, by providing the guide block 32 on the fixed shell 3 and the guide groove 43 on the sliding side plate 4 and slidably connecting them, a precise and stable guiding mechanism is provided for the vertical movement of the sliding side plate 4 relative to the fixed shell 3. This design effectively avoids problems such as offset, shaking, or jamming of the sliding side plate 4 during movement, ensuring that the sliding side plate 4 can move smoothly and steadily up and down along a predetermined trajectory, greatly improving the overall reliability and stability of operation, and also improving the accuracy and smoothness of operation.

[0030] like Figure 5 As shown, in one embodiment, each handle base 12 has a first sidewall 121, and the first sidewalls 121 of the two handle bases 12 face each other. The first sidewalls 121 are provided with a second mounting groove 1212. The handle assembly also includes a rubber pad 6, which is disposed in the second mounting groove 1212, with a portion of the rubber pad 6 protruding from the second mounting groove 1212 for contact with the surface of the door body 200. Thus, in one aspect, the first sidewalls 121 of the two handle bases 12 face each other and are provided with a second mounting groove 1212. This design provides a clear and specific installation position for the rubber pad 6. During assembly, the rubber pad 6 can be accurately embedded in the second mounting groove 1212 to achieve precise positioning, which helps to improve the installation efficiency of the entire handle assembly. At the same time, the second mounting groove 1212 plays a certain role in limiting and fixing the rubber pad 6, preventing the rubber pad 6 from shifting or falling off during use, and ensuring the stability of the handle assembly structure. Secondly, the rubber pad 6 is partially exposed in the second mounting groove 1212 and contacts the surface of the door body 200. When the handle assembly is operated to open and close the door, the rubber pad 6 can play a good shock absorption and buffering role. When the handle seat 12 is subjected to external force, the rubber pad 6 can absorb and disperse part of the impact force, reduce the direct rigid collision between the handle seat 12 and the door body 200, avoid noise caused by the collision, and at the same time reduce the risk of damage to the door body 200 and the handle assembly, and extend the service life of the door body 200 and the handle assembly.

[0031] like Figure 3 and Figure 5As shown, in one embodiment, each handle base 12 has a first sidewall 121, and the first sidewalls 121 of two handle bases 12 face each other. The first sidewall 121 is provided with a first mounting groove 1211. The transmission arm 41 is located in the first mounting groove 1211 and can move up and down relative to the first mounting groove 1211. With this configuration, firstly, the first mounting groove 1211 is provided in the first sidewall 121 of each handle base 12. The first mounting groove 1211 provides a clear positioning and fixed position for the installation of the transmission arm 41. During the assembly process, the operator can quickly and accurately put the transmission arm 41 into the first mounting groove 1211. This design makes full use of the internal space of the handle base 12, making the structure of the entire handle assembly more compact. It realizes the installation and movement function of the transmission arm 41 in a limited space, avoiding the problems of structural complexity and excessive space occupation that may result from the exposed transmission arm 41. It is especially suitable for door lock or door and window handle systems with high space requirements. Secondly, the first mounting groove 1211 provides a precise guide track for the up and down movement of the transmission arm 41. When the transmission arm 41 moves within the first mounting groove 1211, it can only move up and down along the extension direction of the groove, effectively limiting the offset and sway of the transmission arm 41 in other directions, ensuring the accuracy and stability of the movement of the transmission arm 41. This helps to improve the precision of the handle assembly operation, allowing users to experience a smoother and more fluid operation when opening and closing the door.

[0032] like Figure 2 and Figure 3 As shown, in one embodiment, the fixed shell 3 is provided with a first fastening hole 31, and the connecting shell 11 is provided with a second fastening hole 113; the handle assembly also includes a fastener 9, which is connected to the first fastening hole 31 and the second fastening hole 113 so that the fixed shell 3 and the connecting shell 11 can be clamped and fixed to the door frame 5. Thus, in the first aspect, by using the first fastening hole 31 of the fixed shell 3 and the second fastening hole 113 of the connecting shell 11, and with the fastener 9, both are directly clamped and fixed to the door frame 5, eliminating the need to drill holes in the door frame 5, greatly simplifying the installation process and reducing the installation difficulty. Even non-professionals can complete the installation operation relatively easily. Furthermore, since the step of drilling holes in the door frame 5 is eliminated, problems such as inaccurate positioning and unsuitable drilling size that may occur during drilling are avoided, thereby significantly reducing the installation time and improving installation efficiency, which is especially suitable for large-scale production and rapid installation scenarios. Secondly, the fact that no fastening holes need to be set in the door frame 5 allows the handle assembly to be applied to more types of doors 200. Regardless of whether the door 200 is made of glass, wood, metal, or plastic, or has different thicknesses and shapes, as long as the fixing shell 3 and the connecting shell 11 can hold the door frame 5 with the fasteners 9, a stable installation can be achieved, which greatly expands the product's applicability.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, at least two sets of the first fastening hole 31, the second fastening hole 113, and the fastener 9 are provided.

[0034] In one embodiment, at least one of the first fastening hole 31 and the second fastening hole 113 is provided with an internal thread, and the fastener 9 is provided with an external thread that mates with the internal thread.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the actuating block 2 is slidably disposed on the handle seat 12 in the vertical direction; one of the transmission arm 41 and the actuating block 2 is provided with the transmission block 21, and the other is provided with the transmission groove 42. The transmission block 21 and the transmission groove 42 are engaged to form a transmission between the transmission arm 41 and the actuating block 2. In this way, the user can directly move the actuating block 2 up and down to drive the transmission arm 41 to move up and down. Under the drive of the transmission arm 41, the sliding side plate 4 drives the locking rod 8 to move up and down synchronously. The structure is simple. Thus, firstly, the user can directly move the actuating block 2 up and down to drive the transmission arm 41 to move, thereby causing the sliding side plate 4 to drive the locking rod 8 to move up and down synchronously. This operation method conforms to people's daily cognitive habits of vertical direction, and the operation is intuitive and easy to understand; no complicated operation steps or learning process are required, and even first-time users can quickly master it, greatly improving the convenience and comfort of use. Secondly, the actuating block 2 and the transmission arm 41 are connected by the transmission block 21 and the transmission groove 42. This direct connection reduces intermediate transmission links, allowing the user's actuation operation to be quickly and accurately transmitted to the transmission arm 41 and the locking lever 8, achieving a rapid response and providing the user with a smooth and responsive operating experience. Thirdly, the entire transmission structure consists of only a few simple components such as the actuating block 2, the transmission arm 41, the transmission block 21, and the transmission groove 42, without complex mechanical structures or unnecessary parts, making the overall structure of the handle assembly more compact. This compact design not only saves space, facilitating installation and layout within limited space, but also makes the product's appearance more concise and aesthetically pleasing.

[0036] It should be noted that in some other embodiments, the actuating block 2 may also be rotatably mounted on the handle seat 12, and a transmission component is provided between the actuating block 2 and the sliding side plate 4. By rotating the actuating block 2, the transmission component can convert the rotation of the actuating block 2 into the up and down movement of the sliding side plate 4. The transmission component may be, but is not limited to, a gear and rack transmission component or a cam and slider transmission component, whichever is selected according to actual needs.

[0037] like Figure 5As shown, in one embodiment, a fixing structure is provided between the connecting shell 11 and the handle seat 12, and the connecting shell 11 and the handle seat 12 are fixedly connected by the fixing structure. In this way, the fixing structure can tightly connect the connecting shell 11 and the handle seat 12 together to form a stable whole, avoiding loosening, separation or relative displacement between the connecting shell 11 and the handle seat 12, thereby improving the structural strength and stability of the entire handle assembly and extending the service life of the product.

[0038] like Figure 5 As shown, in one embodiment, the fixing structure includes a third mounting groove 1213 disposed on the first sidewall 121, and the two sides of the connecting shell 11 are respectively snapped into the third mounting groove 1213 of the two handle seats 12. Thus, the installation process of this snap-fit ​​fixing structure is relatively simple, requiring no complex tools or professional skills. The operator only needs to align the two sides of the connecting shell 11 with the third mounting groove 1213 on the handle seat 12, and then apply a certain pressure to snap the connecting shell 11 into the groove to complete the installation, greatly shortening the installation time and improving installation efficiency, especially suitable for large-scale production and rapid on-site installation scenarios. Furthermore, the third mounting groove 1213 provides a clear positioning for the installation of the connecting shell 11, allowing the operator to quickly and accurately place the connecting shell 11 in the correct position during installation, reducing the debugging and correction time during the installation process, improving the accuracy and consistency of assembly, and reducing the failure rate caused by improper installation.

[0039] It should be noted that in some other embodiments, the fixing structure may also be, but is not limited to, screws, pins, or rivets, etc., and can be selected according to actual needs, without being limited to one.

[0040] like Figure 5 As shown, in one embodiment, the connecting shell 11 includes a connecting block 112 and two opposing connecting plates 111. The connecting block 112 is connected between the two connecting plates 111 and is provided with the second fastening hole 113 described in the above embodiment. A third cavity for accommodating the door body 200 is formed between the two connecting plates 111. The two connecting plates 111 are respectively snapped into the third mounting grooves 1213 of the two handle seats 12. Thus, the structure of the two opposing connecting plates 111 and the connecting block 112 in the middle can better adapt to the spatial layout and structural requirements between the two handle seats 12. The connecting plates 111 can be specifically designed according to the shape of the handle seat 12 and the position of the third mounting groove 1213, while the connecting block 112 can play a connecting and supporting role in the middle, so that the entire connecting shell 11 can fit tightly with the handle seat 12 and other components to meet the overall design requirements of the product.

[0041] like Figure 5As shown, in one embodiment, both connecting plates 111 are U-shaped. This shape design increases the contact area and engagement depth between the connecting plate 111 and the third mounting groove 1213. The two sides of the U-shape can be better embedded in the third mounting groove 1213, providing stronger clamping force and friction, and further enhancing the stability of the connection.

[0042] It should be noted that in some other embodiments, the connecting shell 11 and the two handle bases 12 can also be integrally formed or welded together.

[0043] like Figure 3 and Figure 4 As shown in the illustration, this application also provides a handle installation structure, including a handle assembly as described in any of the above embodiments, and a door frame 5, with a fixing shell 3 fixed to the door frame 5. Thus, the fixing shell 3 securely fixes the handle assembly to the door frame 5, forming a reliable connection system. The door frame 5, as an important supporting structure of the door 200, possesses high strength and stability. The connection between the fixing shell 3 and the door frame 5 greatly improves the stability and reliability of the entire handle installation structure, extending the product's service life.

[0044] like Figure 3 As shown, in one embodiment, a fourth mounting groove 51 extending along its length is provided on the first side of the door frame 5, and the fixing shell 3 is fixed to the fourth mounting groove 51. Thus, the groove wall of the fourth mounting groove 51 restricts the fixing shell 3, preventing unnecessary displacement of the fixing shell 3 in the horizontal and vertical directions. This structural constraint ensures that the fixing shell 3 remains in the correct installation position even when subjected to external impact, guaranteeing the normal use and operational accuracy of the handle assembly.

[0045] like Figure 4 As shown, in one embodiment, a fifth mounting groove 52 is provided on the second side of the door frame 5. One end of the connecting shell 11 abuts against the fifth mounting groove 52. The fixing shell 3 and the connecting shell 11 can jointly clamp and fix the door frame 5. The fifth mounting groove 52 provides positioning and support for the connecting shell 11. One end of the connecting shell 11 abuts against the fifth mounting groove 52, and the other end cooperates with the fixing shell 3 to clamp the door frame 5, which can effectively limit the displacement of the connecting shell 11 in the horizontal and vertical directions. At the same time, the clamping effect of the fixing shell 3 and the connecting shell 11 also limits the shaking of the handle assembly relative to the door frame 5, ensuring that the handle remains stable during operation and improving the user experience.

[0046] like Figure 2 and Figure 4As shown, in one embodiment, the door frame 5 is provided with a clearance hole 53, which is used to avoid the fastener 9 in the above embodiment. The fastener 9 can pass through the clearance hole 53 to connect with the second fastening hole 113.

[0047] Example 2 like Figure 1 and Figure 2 As shown, this application embodiment also provides a door and window system, including a door body 200, an upper track 100, a lock box 7, and a lock rod 8. It also includes a handle mounting structure as described in any embodiment of embodiment one. The lock box 7 is disposed on the upper track 100, and a latch is provided at one end of the lock rod 8. Under the action of the lock rod 8, the latch can engage or disengage with the lock box 7 to achieve locking or unlocking. The lock rod 8 is connected to the sliding side plate 4 and moves up and down synchronously with the sliding side plate 4. During assembly, the door and window system allows the fixed shell 3 and the sliding side plate 4 to be connected, and both the fixed shell 3 and the connecting shell 11 are fixed in relative positions to the door frame 5, thus forming a whole from the fixed shell 3, handle shell 1, sliding side plate 4, and door frame 5. Finally, the door frame 5 is connected to the door body 200. This installation method is not affected by the thickness difference of the door body 200, and unlike existing technologies, it does not require adjusting the adhesive position of the handle seat 12 to consider the thickness of the door body 200, greatly simplifying the installation process and improving installation efficiency. Furthermore, since the fixed shell 3, handle shell 1, sliding side plate 4, and door frame 5 form a stable overall structure, the installation position of the handle seat 12 relative to the transmission arm 41 will not be affected by factors such as adhesive and the thickness of the door 200. This ensures that the transmission arm 41 and the actuating block 2 can always maintain a stable transmission connection, ensuring that the power can be accurately and stably transmitted to the lock rod 8 when operating the handle, thereby realizing reliable locking and unlocking of the door lock and improving the safety and stability of the door lock.

[0048] In summary, the handle assembly and handle mounting structure disclosed in this utility model can bring at least the following beneficial technical effects: (1) During assembly, the fixed shell 3, handle shell 1, sliding side plate 4 and door frame 5 can form a stable overall structure. The installation position of handle seat 12 relative to transmission arm 41 will not be affected by factors such as adhesive and door thickness 200. This allows the transmission arm 41 and toggle block 2 to always maintain a stable transmission connection. (2) The rubber pad 6 is partially exposed in the second mounting groove 1212 and contacts the surface of the door body 200. When the door is opened and closed, the rubber pad 6 can play a good shock absorption and buffering effect. When the handle seat 12 is subjected to external force, the rubber pad 6 can absorb and disperse part of the impact force, reduce the direct rigid collision between the handle seat 12 and the door body 200, avoid noise caused by the collision, and also reduce the risk of damage to the door body 200 and the handle assembly. (3) By using the first fastening hole 31 of the fixed shell 3 and the second fastening hole 113 of the connecting shell 11, the two are directly clamped and fixed on the door frame 5 with the fastener 9. There is no need to drill holes in the door frame 5, which greatly simplifies the installation process and reduces the installation difficulty. Even non-professionals can complete the installation operation relatively easily. (4) The fact that no fastening holes need to be set in the vertical frame 5 of the door body allows the handle assembly to be applied to more types of door bodies 200.
