Description

Technical Field

[0001] This utility model relates to the field of handle technology, specifically a concealed handle. Background Technology

[0002] Handles (or levers) serve as the basic mechanical interface for humans to operate objects. Their core function is to provide an effective force application point for structures such as doors, windows, drawers, and cabinets, and to convert human power into mechanical actions of opening or closing through the lever principle.

[0003] Currently, the mainstream products on the market are still mainly fixed protruding handles, and this design has significant drawbacks:

[0004] 1. Space encroachment problem: Protruding structures (usually protruding 20-50mm from the mounting surface) can easily interfere with adjacent objects in narrow spaces (such as built-in furniture and dense storage cabinets), forcing the design phase to reserve extra operating space and severely restricting space utilization.

[0005] 2. Significant safety hazards: Protruding parts can become accident-causing factors in dynamic environments, easily leading to scrape accidents (such as children bumping into each other or clothing getting caught in crowded environments).

[0006] Based on this, the present invention proposes a concealed handle. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model proposes a concealed handle that, through optimized mechanical linkage (dynamic cooperation between locking pin and locking component), a dual-spring division of labor mechanism (torsion spring pop-out + spring locking), and a zero-exposed structure design, makes the device simple to operate, easy to use, and greatly reduces the space occupied by the device, avoids scratches and accidents, and improves the practicality of the device.

[0008] The technical solution to achieve the purpose of this utility model is as follows: a concealed handle, including a shell, two mounting bolts on the shell, a base fixedly connected to the shell by fixing bolts, a fixing seat fixedly connected to the shell, and further comprising;

[0009] A sliding block is slidably connected to a fixed base. A spring is fixedly connected to the sliding block and the spring is fixedly connected to the fixed base. A locking pin is rotatably connected to the sliding block. A handle is rotatably connected to the base. A connecting shaft and a torsion spring are provided at the connection between the base and the handle. A locking element is fixedly connected to the handle and the locking element is compatible with the locking pin.

[0010] Preferably, a lever fork is slidably connected to the base, and a pad is provided on the lever fork.

[0011] Preferably, the shift fork is fixedly connected to two limiting blocks via connecting posts.

[0012] Preferably, the connecting shaft is provided with two gaskets, and the handle is provided with a rotating rod.

[0013] Preferably, the two ends of the rotating rod are respectively fixedly connected to a second connecting shaft and a third connecting shaft, the second connecting shaft being rotatably connected to the handle, and the third connecting shaft being rotatably connected to the shift fork.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] In this invention, the user only needs to press the handle lightly, and its rotation around the connecting shaft will drive the locking mechanism to push the locking pin, causing the locking pin to disengage from the locking mechanism. The torsion spring will then release its elasticity, instantly ejecting the handle from the outer shell into the working state. No additional operation is required throughout the process. After use, pressing down on the handle will cause the rotating rod to move laterally in conjunction with the shift fork. The locking mechanism and the locking pin will cooperate to push the sliding block to compress the spring. When the handle is fully inserted, the spring will rebound and drive the locking pin to engage with the locking mechanism for automatic concealment. This makes the device simple to operate and easy to use, and it also greatly reduces the space occupied by the device, improving its practicality. Attached Figure Description

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides a concealed handle through improvement. The technical solution of this utility model is as follows:

[0026] like Figures 1-5 As shown, a concealed handle includes a housing 1. The bottom of the housing 1 has a groove to increase the distance of the fork 9, so as to be compatible with more door and window profiles. The housing 1 is provided with two mounting bolts 2, which are used to install and fix the housing 1. A base 3 is fixedly connected to the housing 1 by fixing bolts 4. A fixing seat 5 is fixedly connected to the housing 1.

[0027] A sliding block 6 is slidably connected to a fixed base 5. A spring 7 is fixedly connected to the sliding block 6 and is also fixedly connected to the fixed base 5. A locking pin 8 is rotatably connected to the sliding block 6. A handle 13 is rotatably connected to the base 3. A connecting shaft 15 and a torsion spring 16 are provided at the connection between the base 3 and the handle 13. The torsion spring 16 keeps the handle 13 under clockwise force. After pressing the handle 13, the handle 13 pops out and the rotating rod 18 causes the shift fork 9 to slide to the left. After the handle 13 closes, the shift fork 9 slides to the right. A locking element 1 is fixedly connected to the handle 13. 4. Locking component 14 is compatible with locking pin 8. In a stationary state, spring 7 presses sliding block 6 and locking pin 8 to the left, and locking pin 8 remains vertical. When the left side of locking pin 8 is subjected to force, since the bottom and middle of locking pin 8 abut against sliding block 6, locking pin 8 will drive sliding block 6 to slide to the right. When no force is applied, it returns to the stationary position under the action of spring 7. When the right side of locking pin 8 is subjected to force, locking pin 8 rotates around the top of sliding block 6, and the bottom of locking pin 8 presses spring 7 to the right. When no force is applied, it returns to the stationary position under the action of spring 7.

[0028] Furthermore, such as Figures 2-4 As shown, a fork 9 is slidably connected to the base 3. A pad 10 is provided on the fork 9. The pad 10 is made of plastic and is used to reduce the friction and wear between the fork 9 and the base 3.

[0029] Furthermore, such as Figures 2-4 As shown, two limiting blocks 11 are fixedly connected to the shift fork 9 via connecting posts 12. The limiting blocks 11 are connected to the shift fork 9 via connecting posts 12, clamping the base 3 in the middle to prevent the shift fork 9 from falling off.

[0030] Furthermore, such as Figures 1-4As shown, two washers 17 are provided on the connecting shaft 15. The washers 17 are used to reduce the friction and wear between the handle 13 and the base 3. The handle 13 is provided with a rotating rod 18.

[0031] Furthermore, such as Figures 1-4 As shown, the two ends of the rotating rod 18 are respectively fixedly connected to the second connecting shaft 19 and the third connecting shaft 20. The second connecting shaft 19 is rotatably connected to the handle 13, and the third connecting shaft 20 is rotatably connected to the shift fork 9. The rotating rod 18 drives the shift fork 9 to move.

[0032] The specific working method is as follows: Press the handle 13 to make it rotate around the connecting shaft 15, which drives the locking piece 14 to push the locking pin 8, so that the locking pin 8 is pressed away from the locking piece 14, releasing its restriction on the locking piece 14. At this time, the handle 13 pops out from the outer shell 1 under the action of the torsion spring 16, so that the device is in use. When the handle 13 needs to be stored after use, press down the handle 13, and push the fork 9 to move through the rotating rod 18, so that the rotating rod 18 is embedded in the outer shell 1. Then the locking piece 14 meets the locking pin 8. Press the locking piece 14 to squeeze the locking pin 8, push the sliding block 6 to move, so that the locking pin 8 moves into the locking piece 14, limiting the handle 13, so that the handle 13 retracts back into the outer shell 1 and is hidden.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
