Description

Technical Field

[0001] This utility model belongs to the field of door lock technology and relates to a novel concealed handle. Background Technology

[0002] Handles, as the most common transmission device in door and window hardware, are generally made of zinc-aluminum alloy and function to transmit movement, enabling the opening and closing of windows or doors. Currently available concealed handles rely on the friction between the handle and the base surface to achieve reciprocating motion. This structure easily scratches the base surface, and the fork and base are visible when the handle is opened, which does not conform to modern aesthetics. Furthermore, the locking mechanism uses a spring to secure the handle and the locking block, which is prone to damage. Therefore, there is an urgent need to design a new type of concealed handle that overcomes these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a door and window handle [application number: 200910045270.3]. This door and window handle includes a mechanism with a shaft and a base, a housing with a through hole, and a handle portion. The mechanism is fixedly installed on the door or window via the base, and the housing is fitted onto the mechanism. During installation, the shaft extends from the through hole and is fixedly connected to the handle portion. However, this solution still allows the fork and base to be seen when the handle is opened, and the locking mechanism still relies on a spring, resulting in defects such as easy damage and an unreasonable structure. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems by providing a novel concealed handle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel concealed handle includes a base with a mounting space inside. A sliding groove is connected to the bottom of the mounting space. A fork capable of reciprocating linearly in a horizontal direction is provided in the mounting space. The fork passes through the sliding groove and slides in cooperation with it. A rotatable concealed handle assembly is provided in the base. The concealed handle assembly is connected to the fork by a snap-fit ​​connector. An elastic locking structure is provided in the base. When the concealed handle assembly rotates into the mounting space, the head of the concealed handle assembly engages with the elastic locking structure.

[0007] In the aforementioned novel concealed handle, the concealed handle assembly includes a concealed handle body disposed within a base, a first rivet installed within the placement space, and the tail of the concealed handle body rotatingly engaging with the first rivet.

[0008] In the aforementioned novel concealed handle, a torsion spring is fitted onto the first rivet, and washers are provided between the two ends of the first rivet and the inner wall of the base.

[0014] In the aforementioned novel concealed handle, the elastic locking structure includes a locking block disposed within the base. The locking block is connected to the base via a second rivet. Washers are provided between the two ends of the second rivet and the inner wall of the base. The locking block engages with the head of the concealed handle body.

[0015] In the aforementioned novel concealed grip, the bottom of the locking block is provided with an elastic steel sheet.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. In the process of use, the hidden handle assembly of this utility model is designed as a rotatable storage structure. It can be turned out for operation when in use and stored in the placement space when not in use. This saves space and improves the overall appearance and aesthetics. At the same time, through reasonable mechanical structure design, the stability of the handle in the rotating and stored states is guaranteed.

[0018] 2. This utility model uses an elastic steel sheet instead of a traditional spring as the locking component.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1-6As shown, a novel concealed handle includes a base 1, which has a placement space 2. The bottom of the placement space 2 is connected to a sliding groove 3. The placement space 2 is provided with a fork 4 that can reciprocate linearly in the horizontal direction. The fork 4 passes through the sliding groove 3 and slides with the sliding groove 3. The base 1 is provided with a rotatable concealed handle assembly 5. The concealed handle assembly 5 and the fork 4 are connected by a snap-fit ​​connector 6. The base 1 is provided with an elastic locking structure 7. When the concealed handle assembly 5 rotates into the placement space 2, the head of the concealed handle assembly 5 engages with the elastic locking structure 7.

[0030] In this embodiment, the concealed handle assembly 5 is installed in the placement space 2 and can rotate around a fixed axis. The concealed handle assembly 5 and the shift fork 4 are connected by a snap-fit ​​connector 6. This connection method can efficiently convert the rotation of the handle assembly into the linear motion of the shift fork 4. The elastic locking structure 7 provided in the base 1 precisely engages with the head of the concealed handle assembly 5 when the concealed handle assembly 5 is rotated and stored in the placement space 2, thereby stably fixing the handle in the storage position. By combining the concealed handle assembly 5, the concealed sliding structure of the sliding groove 3-shift fork 4, and the elastic locking structure 7, the traditional design mode of exposed handle and loose structure is broken through. The concealed design improves aesthetics and space utilization. The cooperation between the sliding groove and the shift fork realizes the concealment of the transmission components. The elastic locking structure replaces the traditional spring structure, achieving a compact structure and improved lifespan.

[0031] Combination Figure 1-6 As shown, the concealed handle assembly 5 includes a concealed handle body 8 disposed in the base 1, and a first rivet 9 is installed in the placement space 2. The tail of the concealed handle body 8 is rotatably engaged with the first rivet 9.

[0032] Specifically, a first rivet 9 is pre-installed in the placement space 2. The first rivet 9 serves as a fixed shaft. The tail of the concealed handle body 8 is provided with a suitable mounting hole. By fitting the mounting hole onto the first rivet 9, the concealed handle body 8 and the first rivet 9 can be rotated together.

[0033] A torsion spring 10 is fitted on the first rivet 9, and washers 11 are provided between the two ends of the first rivet 9 and the inner wall of the base 1.

[0034] In this embodiment, when the concealed handle body 8 is rotated and unfolded, the torsion spring 10 undergoes elastic deformation and stores elastic potential energy; when the handle is released, the torsion spring 10 releases elastic potential energy, pushing the concealed handle body 8 to automatically rotate back to the storage position.

[0035] Combination Figure 1-6As shown, the snap-fit ​​connector 6 includes a connecting rod 12 disposed between the concealed handle body 8 and the shift fork 4. One end of the connecting rod 12 is rotatably engaged with the concealed handle body 8, and the other end is rotatably engaged with the shift fork 4.

[0036] In this embodiment, when the concealed handle body 8 rotates, the rotational motion is transmitted to the connecting rod 12 through a rotational connection at one end; the connecting rod 12 then transmits the motion to the shift fork 4 through a rotational connection at the other end, thereby driving the shift fork 4 to make horizontal linear motion within the sliding groove 3. By using the connecting rod 12 to connect the concealed handle body 8 and the shift fork 4, and adopting a rotational transmission method, compared with the traditional rigid connection, it can better adapt to the conversion between handle rotation and shift fork linear motion, ensuring smooth and reliable transmission.

[0037] The concealed handle body 8 is provided with a first latching part 13, the fork 4 is provided with a second latching part 14, one end of the connecting rod 12 is rotatably engaged with the first latching part 13, and the other end is rotatably engaged with the second latching part 14.

[0038] In this embodiment, one end of the connecting rod 12 is engaged with the first buckle part 13 through a specific rotating connection structure, and the other end is engaged with the second buckle part 14 in the same way. The buckle connection design allows the connecting rod 12 to be quickly connected to the hidden handle body 8 and the shift fork 4 during installation, without the need for complex fixing methods such as rivets, thus eliminating the need for traditional rivet connections.

[0039] Combination Figure 1-6 As shown, the first buckle part 13 includes a first buckle block 15 disposed at the bottom of the concealed handle body 8. The first buckle block 15 has a first rotating groove 16 and a first slot 17. The connecting rod 12 is provided with a first shaft 18. The first shaft 18 can enter the first rotating groove 16 along the first slot 17 and rotate with the first buckle block 15.

[0040] In this embodiment, during assembly, simply align the first shaft 18 of the connecting rod 12 with the first slot 17, and then gently push the connecting rod 12. The first shaft 18 will then slide into the first rotating groove 16 to complete the connection. During the operation of the handle, when the hidden handle body 8 rotates, the first buckle 15 drives the first shaft 18 to rotate within the first rotating groove 16, thereby transmitting power to the connecting rod 12. Through the cooperation of the first buckle 15, the first rotating groove 16, the first slot 17, and the first shaft 18, a snap-fit ​​rotating connection structure is formed. Compared with traditional connection methods, this structure has significant advantages in terms of convenient assembly and stable connection.

[0041] The second latching part 14 includes a second latching block 19 disposed on the top of the shift fork 4. The second latching block 19 has a second rotating groove 20 and a second slot 21. The connecting rod 12 is provided with a second shaft 22. The second shaft 22 can enter the second rotating groove 20 along the second slot 21 and rotate with the second latching block 19.

[0042] In this embodiment, during the assembly process, the second shaft 22 of the connecting rod 12 is aligned with the second slot 21 and slid into the second rotating groove 20 to complete the connection between the connecting rod 12 and the shift fork 4. When the handle is in operation, the connecting rod 12 transmits power to the shift fork 4 through the rotation of the second shaft 22 in the second rotating groove 20, causing the shift fork 4 to move in the sliding groove 3. The structural design of the second snap-fit ​​part 14 corresponds to that of the first snap-fit ​​part 13, together forming a complete snap-fit ​​connection system, further improving the connection method between the connecting rod 12 and the shift fork 4, and achieving convenient assembly and disassembly while ensuring connection reliability.

[0043] Combination Figure 1-6 As shown, the connecting rod 12 is provided with two anti-interference through grooves 23, and the first buckle 15 and the second buckle 19 each correspond to one anti-interference through groove 23.

[0044] In this embodiment, the anti-interference through groove 23 provides sufficient space for the movement of the first buckle block 15 and the second buckle block 19, avoiding interference and collision between the first buckle block 15, the second buckle block 19 and the connecting rod 12, ensuring that the various components of the handle can operate stably and in coordination, and will not cause movement jamming or damage due to interference between components.

[0045] Combination Figure 1-6 As shown, the elastic locking structure 7 includes a locking block 24 disposed in the base 1. The locking block 24 is connected to the base 1 by a second rivet 25. Washers 11 are provided between the two ends of the second rivet 25 and the inner wall of the base 1. The locking block 24 is engaged with the head of the concealed handle body 8.

[0046] In this embodiment, when the concealed handle body 8 is rotated and stored in the placement space 2, the head of the concealed handle body 8 is precisely engaged with the locking block 24. Under the fixation of the second rivet 25, the locking block 24 can stably interact with the handle head to firmly fix the handle in the storage position.

[0047] Combination Figure 1-2 As shown, the bottom of the card block 24 is provided with an elastic steel sheet 26.

[0048] In this embodiment, an elastic steel sheet 26 is provided at the bottom of the locking block 24. The elastic steel sheet 26 has good elasticity and fatigue resistance. When the concealed handle body 8 is rotated and stored, the handle head pushes the locking block 24, and the elastic steel sheet 26 undergoes elastic deformation. When the handle head reaches the locking position, the elastic steel sheet 26 returns to its original position, providing elastic force to the locking block 24, so that the locking block 24 is tightly locked with the head of the concealed handle body 8. The structure of the elastic steel sheet 26 is more compact, occupies less space, and has higher fatigue resistance. It can maintain stable elastic performance during long-term use and is not prone to fatigue failure.

[0049] The working principle of this utility model is as follows:

[0050] When the handle is needed, pull the concealed handle body 8 outward to allow it to rotate and unfold around the first rivet 9. During the rotation of the handle, the connecting rod 12 of the snap-fit ​​connector 6 drives the shift fork 4 to slide horizontally within the sliding groove 3, thereby enabling the opening and closing of doors, windows, or cabinets. After use, turn the handle back to the placement space 2. The handle head touches the locking block 24, and the elastic steel sheet 26 deforms under force and then resets, locking the handle in place and restoring the handle to its concealed state. Throughout the process, the snap-fit ​​connection ensures stable power transmission, the elastic steel sheet provides reliable locking, and all components work together to achieve efficient and stable operation of the handle.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.

[0052] Although this document frequently uses terms such as base 1, mounting space 2, sliding groove 3, shift fork 4, concealed handle assembly 5, snap-fit ​​connector 6, elastic locking structure 7, concealed handle body 8, first rivet 9, torsion spring 10, washer 11, connecting rod 12, first snap-fit ​​part 13, second snap-fit ​​part 14, first snap block 15, first rotating groove 16, first slot 17, first shaft 18, second snap block 19, second rotating groove 20, second slot 21, second shaft 22, anti-interference through groove 23, snap block 24, second rivet 25, elastic steel sheet 26, the possibility of using other terms is not excluded.
