Description

Technical Field

[0001] The utility model relates to a locking linkage handle assembly, belonging to the technical field of assembly. Background Art

[0002] The outside opening handle is a necessary mechanism for opening the vehicle door. The vehicle door lock is opened through the handle mechanism and the pull rod transmission. The traditional outside opening is transmitted through the pull rod structure. The connection between the pull rod and the lock body produces perceptual problems such as a sense of frustration, abnormal noise, and a large opening force. In the traditional outside handle, the outside opening rocker arm is installed on the linkage arm bracket and the sub-assembly A is installed on the sub-assembly B and fixed by two elastic cylindrical pins.

[0003] There are still some problems in the use of the existing locking linkage handle assembly. This assembly method requires workers to knock the elastic cylindrical pin in a little bit first, and then press it completely in through a riveting machine. This is time-consuming, labor-intensive, and difficult to disassemble. After disassembly, the mounting holes of the parts are worn and cannot be reused. At the same time, a gap is easily generated between the assembly body and the mounting groove during installation, causing the assembly body to shake inside. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1 Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A locking linkage handle assembly comprises a main body 1, a fingerprint groove 2 is provided inside the main body 1, a rotating handle 3 is rotatably connected to the outer side of the main body 1, a threaded tube 4 is fixedly connected to the outer side of the main body 1, a screw 5 is threadedly connected to the inner side of the threaded tube 4, a rotating cover 6 is fixedly connected to the outer side of the screw 5, an extrusion rod 7 is fixedly connected to the bottom of the screw 5, an air pressure box 8 is fixedly connected to the inside of the main body 1, an elastic air bag 9 is fixedly connected to the top of the air pressure box 8, an air outlet pipe 10 is fixedly connected to the bottom of the elastic air bag 9, a return spring 11 is fixedly connected to the inner wall of the air pressure box 8, a sliding plate 12 is fixedly connected to the outer side of the return spring 11, a moving rod 13 is fixedly connected to the outer side of the sliding plate 12, a sealing ring 14 is fixedly connected to the outer side of the air pressure box 8, a push rod 15 is fixedly connected to the outer side of the moving rod 13, and a clamping plate 16 is fixedly connected to the outer side of the push rod 15.

[0026] Specifically, Figure 1 As shown, the threaded tube 4 is symmetrically distributed on the outside of the overall body 1, the screw 5 is rotatably connected to the inside of the threaded tube 4 through the rotating cover 6, the air outlet pipe 10 is fixedly connected to the inside of the air pressure box 8, and the air outlet pipe 10 is located between the two sliding plates 12, the extrusion rod 7 is located directly above the elastic airbag 9, the push rod 15 is slidably connected to the inside of the sealing ring 14, the number of the clamping plates 16 and the push rod 15 is the same, and the clamping plates 16 and the push rod 15 are symmetrically distributed on the outside of the overall body 1.

[0027] In this embodiment: by setting up the overall body 1, when the overall body 1 needs to be installed, it is first placed in the installation groove of the door frame, and then by rotating the rotating cover 6, the rotating cover 6 drives the screw 5 to rotate inside the threaded tube 4, and then the screw 5 drives the extrusion rod 7 to move downward, and the movement of the extrusion rod 7 will squeeze the elastic airbag 9 on the top of the air pressure box 8, so that the gas inside the elastic airbag 9 enters the interior of the air pressure box 8 through the outlet pipe 10. When the gas enters the interior of the air pressure box 8, the internal pressure increases. The sliding plate 12 inside the air pressure box 8 will squeeze the return spring 11 to move to both sides. The movement of the sliding plate 12 drives the push rod 15 on the outside of the moving rod 13 to move inside the sealing ring 14, so that the push rod 15 drives the clamping plate 16 to move, and then the clamping plate 16 enters the inside of the installation groove, achieving the effect of convenient installation. When disassembly is required, it is only necessary to drive the screw 5 to flip through the rotating cover 6, so that the gas can enter the elastic airbag 9 again. At this time, the clamping plate 16 returns to its original position under the action of the return spring 11.

[0028] Example 2 Please refer to Figure 1 , Figure 2 and Figure 5The difference between this embodiment and the first embodiment is that a compression spring 17 is fixedly connected to the outer side of the assembly body 1 , and a positioning plate 18 is fixedly connected to the outer side of the compression spring 17 .

[0029] Specifically, Figure 1-5 As shown, the compression springs 17 are symmetrically distributed between the main body 1 and the positioning plate 18 , and the positioning plate 18 is located on both sides of the main body 1 .

[0030] In this implementation scheme: by setting up the total body 1, since the compression spring 17 and the positioning plate 18 are fixedly connected to the outside of the total body 1, the positioning plate 18 is first moved to the outside close to the total body 1, and then the total body 1 is installed in the internal mounting groove of the door frame. At this time, the positioning plate 18 will move to both sides under the action of the compression spring 17, so that the positioning plate 18 is close to the inner wall of the mounting groove, preventing the total body 1 from shaking inside the mounting groove.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
