Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and more specifically, to a handle. Background Art

[0002] A handle, also known as a pull or door handle, is a device mounted on a door to help open and close it. Handles are usually made of materials such as metal and plastic, but can be made of a variety of materials including ceramic, solid wood, glass, crystal, etc. Door handles come in a variety of designs and styles and can be in different shapes such as a single hole ball, bar, or in a specific style such as Japanese, Chinese, modern, European, etc.

[0003] The existing handle is assembled through components such as a button, a top shaft, a top block, a long rotating shaft, a tightening hook and a torsion spring. However, since there are many parts for unlocking the handle by assembling the handle, the handle assembly process is relatively cumbersome. The handle is generally unlocked by driving the tightening hook to unlock through the long rotating shaft. However, the rotating shaft is too long, and positioning errors are likely to occur during the assembly of the handle. Furthermore, since the existing handle generally uses a long rotating shaft to drive the tightening hook to unlock, it has high requirements on the performance of the torsion spring. After a long period of time of using the button to press and unlock through the spring, the spring is likely to age and be difficult to reset, thereby affecting the use effect of the handle.

[0004] In summary, there is an urgent need for a handle with a simple structure and better use effect to solve the above problems. Utility Model Content

When the crank 5 rotates, it rotates in cooperation with the transmission bar 6 and drives the lock tongue 7 to rotate, thereby hooking the fixing rod on the fixing seat assembly 9 for locking.

[0026] like Figure 1 , Figure 4-Figure 5As shown, it also includes a protective plate 10, a lock core 11, a clamping rod 12 and a spring III 13. The protective plate 10 is installed at the rear position of the lower inner side of the base 1 by screws, and the right side of the protective plate 10 extends to the right side of the base 1. The protective plate 10 is used to cover the components for installation; the lock core 11 is rotatably installed in the middle position of the lower side of the base 1, and an eccentric wheel is provided at the end of the lock core 11, and a spacing distance is left between the eccentric wheel at the end of the lock core 11 and the left side of the protective plate 10. The rear end of the lock core 11 is in rotational contact with the protective plate 10, and the lock core 11 is provided to further assist in locking the door panel; the clamping rod 12 is slidably connected to the extended part on the right side of the protective plate 10, and the left end of the clamping rod 12 is in sliding contact with the lock core 11. The sliding direction of the clamping rod 12 is toward the right side of the base 1, and the right end of the clamping rod 12 extends into the extended part on the right side of the protective plate 10; the spring III 13 is connected between the inner side of the protective plate 10 and the clamping rod 12.

[0027] like Figure 4-Figure 5 As shown, a protective sleeve 14 is also included, and the protective sleeve 14 is connected to the door frame by screws. When the door panel is closed, the clamping rod 12 will slide in contact with the inner side of the protective sleeve 14, thereby further fixing the door panel and the door frame.

[0028] First, install the base 1 on the door panel, and install the fixed latch 101, handle 2, button 3, spring I 4, crank 5, transmission bar 6, lock tongue hook 7 and spring II 8 on the base 1 in sequence, and continue to install the protective plate 10, lock core 11, clamping rod 12 and spring III 13 protective cover 14 on the base 1. After the installation of the base 1 is completed, then install the fixed seat assembly 9 on the contact surface close to the base 1 on the door frame, and open an installation groove for installing the protective cover 14 on the door frame. After the installation of the fixed seat assembly 9 and the protective cover 14 is completed, first use the key to insert into the lock core 11, and twist the key so that the eccentric wheel at the rear end of the lock core 11 is in the protective plate 10. The lock core 11 is rotated counterclockwise. At this time, the eccentric wheel at the rear end of the lock core 11 stops contacting the card rod 12, and contacts one side of the protective plate 10, leaving a gap between the card rod 12 and the eccentric wheel at the rear end of the lock core 11. At this time, the spring III 13 between the card rod 12 and the protective plate 10 stretches, driving the card rod 12 to approach and contact the rear end of the lock core 11, but one end of the card rod 12 completely slides into the protective plate 10 when the spring III 13 stretches. Then, the button 3 is pressed backward and the handle 2 is held to close the door panel in the door frame. In the process of pressing the button 3, the spring I4 will be compressed and shortened on the partition in the middle of the handle 2 as the button 3 slides backward, and the rear end of the button 3 pushes One side of the crank 5 causes the other side of the crank 5 to rotate on the fixed latch 101 on one side of the base 1, and the middle part of the crank 5 will squeeze the spring II 8 to compress it. When one side of the crank 5 rotates, it will drive the transmission bar 6 to rotate and tilt and drive the lock tongue hook 7 to rotate and tilt. When the button 3 is no longer pressed, the spring I4 and the spring II8 stretch and lengthen to reset and drive the button 3 and the crank 5 to reset. The spring II8 stretches and lengthens to drive the crank 5 to reset, and at the same time, it drives the transmission bar 6 to drive the lock tongue hook 7 to hook the fixed rod on the fixed seat assembly 9. By arranging the spring I4 and the spring II8, the reset of the button 3 is smoother, so that the door panel is passed through the crank 5 and the fixed seat assembly. Component 9 is locked in the door frame, and the crank 5 drives the transmission bar 6 to move through the reset of spring II 8, thereby driving the lock tongue hook 7 to lock and unlock the fixed rod of the fixed seat component 9, which changes the previous structural connection method that requires the use of a long rotating shaft and a tightening hook for locking and unlocking, further realizes a simpler and more efficient unlocking method, and improves the reliability of unlocking the door frame. When it is necessary to disassemble and replace the components connected to the base 1, the handle 2 can be directly disassembled to inspect the inside of the base 1. Since the button 3 and the spring I4 are connected to the handle 2, when the handle 2 is disassembled, it is also further convenient to replace and repair the button 3 and the spring I4.

[0029] Obviously, the embodiments described above are only part of the embodiments of the present utility model, rather than all of the embodiments. They only express the preferred implementation mode of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present utility model.

[0030] It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, they can also make several modifications, increases and decreases in quantity, improvements and substitutions. Therefore, based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the utility model.
