The holding part 20 is used by a user to grasp the door handle 100 to fold and unfold, and the torsion spring 30 Disposed in the grip portion 20 , one end can be connected to the grip portion 20 , and the other end is connected to the mount 10 . When the user grasps the grip portion 20 and turns over, the first free end 31 of the torsion spring 30 turns over with the grip portion 20, the second free end 32 is fixed, and the applied force stretches the torsion spring 30 until the door When the handle 100 is in the unfolded state and the door body 220 is opened, when the grip portion 20 is released, the grip portion 20 tends to return to the folded position due to the elastic recovery of the torsion spring 30 . In this embodiment, the gripping portion 20 has a U-shaped structure with symmetrical structures on both sides, including a first lateral portion (not marked), a second lateral portion (not marked), and a first lateral portion and a second lateral portion. Tie rods (not labeled) between the parts.

In order to limit the door handle 100 when the door body 220 is opened by the door handle 100 , the grip portion 20 has a first limiting portion 21 , and the movable assembly 50 is movably installed on the mounting base 10 , and the movable assembly 50 has a second limiting portion 21 . For the limiting portion 51, when the door handle 100 is closed, the moving assembly 50 moves upward, and the first limiting portion 21 and the second limiting portion 51 are released from the limiting positions, thereby realizing any rotation of the grip portion 20 relative to the mounting seat 10, while the When the door handle 100 is opened, the moving assembly 50 moves downward, and the second limiting portion 51 limits the first limiting portion 21 to prevent the first limiting portion 21 from rotating relative to the mounting seat 10, that is, preventing the first limiting portion 21 from rotating. The part 21 is rotated relative to the mount 10, keeping the door handle 100 unfolded during the opening of the door body 220 by the door handle 100.

Specifically, as shown in FIG. 2 to FIG. 7 , in this embodiment, a rotating shaft 40 is pierced through the first lateral portion of the gripping portion 20 , and both ends of the rotating shaft 40 are disposed on the mounting seat 10 . A rotating shaft 40 ′ is pierced through the lateral portion, two ends of the rotating shaft 40 ′ are arranged on the mounting seat 10 ′, and the torsion spring 30 is sleeved on the rotating shaft 40 and located in the holding portion 20 (as shown in FIG. 4 ). In order to limit the torsion spring 30 , as shown in FIG. 7 , a limiting structure 23 is provided on the first lateral portion of the grip portion 20 , and the limiting structure 23 is specifically provided on the opposite side plates on the first lateral portion. , a groove is formed on the opposite side plates, the first free end 31 of the torsion spring 30 is bent into an L shape and limited in the groove, and a fixing plate (not shown) is provided in the mounting seat 10. The fixing plate A through hole is opened on the upper part, and the second free end 32 of the torsion spring 30 is also bent into an L shape, and its end extends into the through hole and hooks the through hole to prevent the second free end 32 from passing through the through hole. out.

As shown in FIG. 5 and FIG. 6 , in order to realize the limit of the door handle 100 , a first limit portion 21 is provided in the second lateral portion of the grip portion 20 , and the movable assembly 50 has a second limit portion 51 . 50 can be positioned in the mounting seat 10' and partially protrudes from the mounting seat 10'. Specifically, the movable assembly 50 includes a limit block 52 and a slider 53 located below the limit block 52. The second limit portion 51 is formed by protruding On the limiting block 52 , the lower end of the sliding block 53 protrudes from the mounting seat 10 ′, the movable assembly 50 is movable in the mounting seat 10 ′, and the first limiting portion 21 passes through the rotating shaft 40 ′.

8 to 13 , the door handle 100 of this embodiment will be described again. When the door body 220 is closed, the moving assembly 50 moves upward in the mounting seat 10 ′, so that the second limiting surface 511 of the second limiting portion 51 is in contact with the second limiting surface 511 of the second limiting portion 51 . The first limiting surfaces 211 of a limiting portion 21 do not interfere with each other, and will not affect the rotation of the gripping portion 20 relative to the mounting base 10/10'. As shown in FIGS. 8 and 9, the upward force exerted on the moving assembly 50 It can be a part on the cabinet body 210, the part can be the cabinet opening, or any other part provided on the cabinet body 210, as long as the lower end of the slider 53 can be abutted and raised when the door body 220 is closed It is enough to move to the second limiting portion 51 and the first limiting portion 21 to disengage from the limiting position.

As long as the upward force on the lower end of the slider 53 is not eliminated, that is, the moving assembly 50 keeps moving upward until the second limiting portion 51 and the first limiting portion 21 are out of position, the grip portion 50 will remain 10/10' relative to the mounting seat Rotation, that is, when the door body 220 is kept closed, the grip portion 20 rotates arbitrarily relative to the mounting base 10/10'. As shown in FIG. 10 and FIG. 11 , when the door body 220 is closed, when the door handle 100 is unfolded to be parallel to the door body 220 (the angle of the door handle 100 is considered to be 90° at this time), at this time, the first The limiting surface 211 is opposite to the second limiting surface 511 of the second limiting portion 51 , and the second limiting surface 511 does not limit the change of the door handle 100 from 90° to 0° or 0° to 90°. And since the upward force acting on the lower end of the slider 53 is not eliminated at this time, after the door handle 100 is released, the torsion spring 30 tends to recover to the natural state, so that the door handle 100 recovers from the 90° unfolded state to 0°. folded state.

As shown in FIGS. 12 and 13 , when the door handle 100 is pulled to a 90° unfolded state and the cabinet body 210 is opened upward, the upward force on the lower end of the slider 53 is eliminated, and the moving assembly 50 moves downward. At 90°, the first limiting surface 211 is opposite to the second limiting surface 511. Therefore, at the moment when the upward force is eliminated, the second limiting portion 51 moves downward along the length direction of the first limiting surface 211, so that the The second limiting portion 51 descends below the rotating shaft 40 ′ or is on the same level as the rotating shaft 40 ′. At this time, the second limiting surface 511 limits the first limiting surface 211 , so that even if there is the elastic restoring force of the torsion spring 30 , Due to the limit of the first limit surface 211 by the second limit surface 511 , the door handle 100 cannot be restored from the 90° unfolded state to the 0° folded state, thereby realizing the self-limiting of the door handle 100 . When the door handle 100 is unfolded to be parallel to the door body 220 and the door body 220 is opened, the force arm can be increased, which is beneficial for the user to achieve the effect of saving effort to open the door.

After the user finishes taking the objects, during the closing process of the door body 220, the door handle 100 hovers at 90°, which is convenient for closing the door and avoids the risk of hand pinching when the door is closed. The upper end of the slider 53 is pushed upward, and the lower end of the slider 53 is subjected to the upward force exerted by the cabinet. At this time, the movable assembly 50 moves up to the second limit portion 51 and the first limit portion 2 is separated from the limit. 20 can be rotated relative to the mounting seat 10/10', therefore, under the action of the torsion spring 30, the door handle 100 is restored from the unfolded state of 90° to the folded state of 0° as shown in FIG. It is high and takes up less space, which increases the packing capacity during transportation.

The door handle 100 of this embodiment does not need to be manually operated, and only the door handle 100 is used to open or close the door body 220, so that the door handle 220 can be unfolded or folded by 90° when the door body 220 is opened, and during the opening of the door body 220, the door The handle 100 can hover at 90° until the door body 220 is closed.

As shown in FIGS. 5 to 13 , in this embodiment, the moving assembly 50 further includes an elastic member, and the elastic member is specifically a spring 54 . The limiting block 52 has a hollow area (not shown), and the spring 54 extends into the A guide post 13 is formed on the inner side wall of the top surface of the installation base 10 ′, and the part of the spring 54 extending out of the hollow area is sleeved on the guide post. 13 on. When the door body 220 is closed, the upward force of the cabinet on the lower end of the slider 53 is transmitted to the spring 54 to compress the spring 54; when the door body 220 is opened by the door handle 100, that is, when the upward force acting on the moving assembly 50 is eliminated , through the elastic restoring force of the spring 54, the limit block 52 and the sliding block 53 can be rapidly moved downward, and the limit block 52 and the sliding block 53 can be stably limited in the mounting seat 10' after moving downward.

As shown in FIG. 6 , in order to install the mounting seat 10 on the door body 220 , a connecting hole 11 and a positioning post 12 are formed on the surface of the mounting seat 10 in contact with the door body 220 .
