DETAILED DESCRIPTION
[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0029] Embodiment 1
[0030] like Figure 1-Figure 5 As shown, the utility model proposes a door handle with a fastening structure, including a cover plate 1, a fastening structure and a cover shell 4. The cover plate 1 is arranged as a hollow structure, and a locking rod 2 for opening the door is rotatably penetrated therethrough, and a fastening structure is arranged at one end of the locking rod 2. The locking rod 2 is detachably connected to a handle 3 through a fastening mechanism. A cover shell 4 for hiding the fastening structure is arranged on the cover plate 1, and a doorbell assembly is arranged on the top thereof.
[0031] like Figure 3 and Figure 4 As shown, the fastening structure includes a spring 5, a pressure plate 6, a plug post 7, a protrusion 8 and a special-shaped through groove. A slot 9 is provided on the locking rod 2. The spring 5 is arranged in the slot 9, and one end of the spring 5 is connected to the pressure plate 6 which is slidably connected to the slot 9. The plug post 7 is installed on the handle 3 and is interlaced with the slot 9. The outer wall of the plug post 7 is provided with a protrusion 8, and a special-shaped through groove for directional movement of the protrusion 8 is provided on the locking rod 2, and the special-shaped through groove is communicated with the slot 9.
[0032] like Figure 3 As shown, the special-shaped through groove includes an insertion section 10, a rotation section 11 and a retraction section 12. The rotation section 11 is arranged at one end between the insertion section 10 and the retraction section 12, and the other end of the insertion section 10 extends to the end face of the locking rod 2. When installing the handle 3, the protrusion 8 on the plug column 7 is inserted into the special-shaped through groove along the socket of the insertion section 10. After being inserted to the bottom, the handle is rotated, and the handle drives the plug column 7 to rotate. During the rotation, the protrusion 8 moves along the rotation section 11 to the end of the retraction section 12.
[0033] like Figure 1As shown, a limiting groove 20 is provided at one end of the lock rod 2 away from the fastening structure, and the cross-sectional shape of the limiting groove 20 is set to be rectangular. Through the limiting groove 20, the cover plate 1 is limitedly plugged with the lock core during installation, and the lock core is driven to rotate through the lock rod 2.
[0034] Embodiment 2
[0035] like Figure 1-Figure 5 As shown, the utility model proposes a door handle with a fastening structure. Based on the above embodiment, this embodiment also records in detail the specific components of the doorbell assembly and the specific connection method between the doorbell assembly and the cover 4.
[0036] like Figure 5 As shown, the doorbell assembly includes a fixed plate 13, a rotating shaft 14, a knocking cone 16 and a tension spring 17. Two groups of fixed plates 13 are provided, which are symmetrically arranged on the cover 4. A rotating shaft 14 is rotatably arranged between the two groups of fixed plates 13. A rotating plate 15 is arranged on the rotating shaft 14. A knocking cone 16 is arranged at one end of the bottom of the rotating plate 15. Tension springs 17 connecting the rotating plate 15 and the cover 4 are arranged on both sides of the knocking cone 16.
[0037] like Figure 5 As shown, an oblique section 18 is provided at one end of the rotating plate 15 facing away from the striking cone 16 , and a pressing section 19 is connected to the rotating plate 15 via the oblique section 18 .
[0038] The cover 4 is made of copper, and when the knocking cone 16 knocks on it, it will make a crisp sound.
[0039] In summary, when the utility model is in use, when the handle 3 is in the installed state, the protrusion 8 thereon is located in the retracting section 12 of the special-shaped through groove. When the handle 3 is rotated, the protrusion 8 thereon will apply a force to the groove wall of the special-shaped through groove, thereby driving the lock rod 2 to rotate, thereby realizing the control of the lock core in the door body. When the damaged handle 3 needs to be disassembled and replaced, a pressing force is applied to the handle 3. Under the action of the pressing force, the handle 3 drives the plug column 7 to squeeze the pressure plate 6. During the squeezing process, on the one hand, the pressure plate 6 presses the spring 5 to cause it to undergo elastic deformation. On the other hand, the protrusion 8 on the plug column 7 moves horizontally along the retracting section 12 until it is pressed into place and the protrusion 8 enters the rotating section 1 1, at this time, rotate the handle 3 so that the protrusion 8 moves along the rotating section 11 to the insertion section 10, and then release the pressing force applied to the handle 3. Under the action of the restoring force of the spring 5, the plug column 7 is driven to disengage from the slot 9. During the disengagement process, the protrusion 8 moves along the insertion section 10. When installing a new handle 3, the reverse operation can be performed; when the doorbell assembly is needed, the pressing section 19 is pressed downward by the thumb, so that the rotating plate 15 drives the knocking cone 16 to lift upward. During the lifting process, the tension spring 17 is driven to produce elastic deformation, and then the pressing section 19 is released. Under the action of the tension spring 17, the knocking cone 16 is driven to quickly knock on the cover 4, thereby producing a crisp doorbell sound.
[0040] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
