Abstract
Description
Technical Field
[0001] The present invention relates to a door lock, in particular to a door lock with adjustable handle torque. Background Art
[0002] As is well known, the movable handle of a common door lock drives other parts to force the handle to reset through the force output by a spring after being pressed down or lifted up. However, since the torque requirements for the handle torque of each manufacturer are different, the handle torques on the market are also different. If the handle torque is too large, it will bring certain difficulties to the elderly, children with not much strength, or some people who cannot fully exert their strength due to reasons during the process of pressing down or lifting up the handle. If the handle torque is too small, the handle may not be able to reset. Therefore, whether the handle torque is too large or too small, it will to a certain extent affect the user's operation experience. Summary of the Invention
[0003] According to the above discussion of the problems, the present invention proposes a door lock with adjustable handle torque. The main feature is that a mechanical structure for adjusting the force output torque of the handle return spring is provided inside the door lock. The user of the door lock can adjust the force output torque of the return spring to achieve the torque required for convenient operation of pressing down the handle to unlock or lifting up the handle to lock for himself or others as much as possible. Brief Description of the Drawings
[0004] Att Figure 1 : Schematic diagram of the structural composition of the present invention; Att Figure 2 : Schematic diagram of the structure of the reset plate of the present invention; Att Figure 3 : Schematic diagram of the structure of the handle connecting piece of the present invention; Att Figure 4 : Schematic diagram of the structure of the spring adjusting piece of the present invention; Att Figure 5 : Effect diagram of the handle reset of the present invention; Att Figure 6 : Effect diagram of the handle movement of the present invention; Detailed Description of the Invention
[0005] The external shape of the present invention consists of two main parts: a handle 1 and a panel or base 2. Inside the panel or base 2, a handle reset plate 3, a tension spring 4, a handle connecting piece 5, a tension spring adjusting piece 6 and an adjusting screw 7 are provided. Among them, the handle reset plate 3 is provided with two buckle ears for hanging the tension spring 4, the handle connecting piece 5 is provided with a cylinder 5-1 that moves tangentially to the handle reset plate 3, and the tension spring adjusting piece 6 is also provided with two buckle ears 6-1 for hanging the tension spring 4.
[0006] The main working principle is that the handle 1 and the handle connecting piece 5 are installed on the panel or the base 2. The handle return plate 3 is hung on the two tangent cylinders 5-1 of the handle connecting piece 5. Under the pulling force of the two side tension springs, the handle return plate 3 is forced to fit on the two tangent cylinders 5-1 of the handle connecting piece 5, as shown in the appendix Figure 5 . When the handle is pressed down or lifted up to drive the handle connecting piece 5 to rotate together, the tangent cylinder 5-1 of the handle connecting piece 5 drives the handle return plate 3 to move upward, as shown in the appendix Figure 6 .
[0007] The tension spring adjusting screws 7 on both sides pass through the panel or the base 2 and are connected to the tension spring adjusting piece 6. By rotating the tension spring adjusting screws 7, the connecting piece of the tension spring adjusting piece 6 can be driven to move up and down reciprocally, so as to achieve the purpose of adjusting the tension torque of the tension spring 4.
Claims
1. It is mainly composed of two major parts: a handle 1 and a panel or base 2. Inside the panel or base 2, there are a handle return plate 3, a tension spring 4, a handle connecting piece 5, a tension spring adjusting piece 6, and an adjusting screw 7. Among them, The handle reset plate 3 is provided with two buckle ears for buckling the tension spring 4. The handle connecting piece 5 is provided with a cylinder 5-1 that moves tangentially to the handle reset plate 3. The tension spring adjusting piece 6 is also provided with two buckle ears 6-1 for buckling the tension spring 4.
2. The handle reset plate 3 is hung on the two tangential cylinders 5-1 of the handle connecting piece 5. When the handle 1 rotates, the tangential cylinder 5-1 of the handle connecting piece 5 drives the handle reset plate 3 to move upward.
3. The tension spring adjusting screw 7 passes through the panel or the base 2 and is connected to the tension spring adjusting piece 6. By rotating the tension spring adjusting screw 7, the connecting piece of the tension spring adjusting piece 6 can be driven to move up and down reciprocally, so as to achieve the purpose of adjusting the tension torque of the tension spring 4.
4. For a door lock with adjustable handle torque according to claim 1, the handle reset plate 3 is provided with buckle ears for buckling the tension spring 4.
5. For a door lock with adjustable handle torque according to claim 1, the handle connecting piece 5 is provided with a cylinder 5-1 that moves tangentially to the handle reset plate 3.
