DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] It should be noted that, in the description of the present invention, terms such as "inside", "outside", "upper" and "lower" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0036] Embodiment 1

[0037] Figure 1 The structure diagram of the door handle 100 of this embodiment installed on the door body 220 is shown, wherein Figure 1 The middle door handle 100 is in a folded state (the angle of the door handle 100 is considered to be 0° at this time). Figures 2 to 7The present embodiment relates to a door handle 100, comprising a mounting seat 10, a gripping portion 20, a torsion spring 30 and a moving assembly 50. The gripping portion 20 is used for the user to grasp the door handle 100 to realize the folding and unfolding of the door handle 100. The torsion spring 30 is arranged in the gripping portion 20, one end of which can be connected to the gripping portion 20, and the other end of which is connected to the mounting seat 10. When the user grasps the gripping portion 20 and flips it, the first free end 31 of the torsion spring 30 flips with the gripping portion 20, and the second free end 32 is fixed. The applied force stretches the torsion spring 30 until the door handle 100 is in the unfolded state and the door body 220 is opened. When the gripping portion 20 is released, the gripping portion 20 tends to return to the folded position due to the elastic recovery of the torsion spring 30. The gripping portion 20 of the present embodiment is a U-shaped structure, and the two sides are symmetrical, including a first lateral portion (not marked), a second lateral portion (not marked) and a pull rod (not marked) located between the first lateral portion and the second lateral portion.

[0038] In order to limit the door handle 100 when opening the door body 220, the gripping portion 20 has a first limiting portion 21, and the movable component 50 is movably mounted on the mounting seat 10, and the movable component 50 has a second limiting portion 51. When the door handle 100 is closed, the movable component 50 moves upward, and the first limiting portion 21 and the second limiting portion 51 are disengaged from the limiting position, thereby realizing any rotation of the gripping portion 20 relative to the mounting seat 10. When the door handle 100 is opened, the movable component 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, to prevent the first limiting portion 21 from rotating relative to the mounting seat 10, thereby keeping the door handle 100 unfolded during the period when the door handle 100 is used to open the door body 220.

[0039] Specifically, if Figures 2 to 7 As shown, in this embodiment, a rotating shaft 40 is provided on the first lateral portion of the gripping portion 20, and both ends of the rotating shaft 40 are arranged on the mounting seat 10. A rotating shaft 40' is provided on the second lateral portion, and both ends of the rotating shaft 40' are arranged on the mounting seat 10'. The torsion spring 30 is sleeved on the rotating shaft 40 and is located in the gripping portion 20 (as shown in FIG. Figure 4 In order to limit the torsion spring 30, as shown in Figure 7As shown, a limiting structure 23 is provided on the first lateral portion of the gripping portion 20. The limiting structure 23 is specifically provided on two 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. A fixing plate (not shown) is provided in the mounting seat 10. A through hole is provided on the fixing plate. The second free end 32 of the torsion spring 30 is also bent into an L shape. The end of the torsion spring 30 extends into the through hole and hooks the through hole to prevent the second free end 32 from coming out of the through hole. In this way, when the gripping portion 20 is turned over, the first free end 31 of the torsion spring 30 is also turned over and tightly pressed against the gripping portion 20 in the groove, and the second free end 32 remains stationary due to being hooked in the through hole.

[0040] like Figure 5 and Figure 6 As shown, in order to achieve the limitation of the door handle 100, a first limiting portion 21 is provided in the second lateral portion of the gripping portion 20, and the moving component 50 has a second limiting portion 51. The moving component 50 can be positioned in the mounting seat 10' and partially extend out of the mounting seat 10'. Specifically, the moving component 50 includes a limiting block 52 and a sliding block 53 located below the limiting block 52, the second limiting portion 51 is convexly formed on the limiting block 52, and the lower end of the sliding block 53 extends out of the mounting seat 10'. The moving component 50 is movable in the mounting seat 10', and the first limiting portion 21 passes through the rotating shaft 40'.

[0041] Recombination Figures 8 to 13 In the door handle 100 of this embodiment, when the door body 220 is closed, the movable assembly 50 moves upward in the mounting seat 10', so that the second limiting surface 511 of the second limiting portion 51 and the first limiting surface 211 of the first limiting portion 21 do not interfere with each other, and will not affect the rotation of the gripping portion 20 relative to the mounting seat 10 / 10'. Figure 8 and Fig. 9 As shown, the upward force applied to the movable component 50 can be a component on the cabinet body 210, which can be a cabinet opening, or any other component provided on the cabinet body 210, as long as the lower end of the slider 53 can be abutted and moved upward to the second limit portion 51 to disengage from the first limit portion 21 when the door body 220 is closed.

[0042] As long as the upward force on the lower end of the slider 53 is not eliminated, that is, the movable assembly 50 continues to move upward until the second limit portion 51 is disengaged from the first limit portion 21, the grip portion 50 will continue to rotate relative to the mounting seat 10 / 10', that is, while the door body 220 remains closed, the grip portion 20 can rotate freely relative to the mounting seat 10 / 10'. Fig.10 and Fig.11As shown, when the door body 220 is closed, 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), the first limiting surface 211 of the first limiting portion 21 and the second limiting surface 511 of the second limiting portion 51 are opposite, and the second limiting surface 511 does not limit the door handle 100 from 90° to 0° or 0° to 90°. And because 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 has a tendency to return to the natural state, so that the door handle 100 is restored from the 90° unfolded state to the 0° folded state.

[0043] like Fig.12 and Fig.13 As shown, when the door handle 100 is pulled to a 90° unfolded state and the cabinet body 210 begins to be opened upward, the upward force at the lower end of the slider 53 is eliminated, and the movable assembly 50 moves downward. Since the first limiting surface 211 is opposite to the second limiting surface 511 when the door handle 100 is at 90°, 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 second limiting portion 51 drops to the bottom of the rotating shaft 40' or is in the same horizontal plane 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 an elastic restoring force of the torsion spring 30, due to the limitation of the second limiting surface 511 on the first limiting surface 211, the door handle 100 cannot be restored from the 90° unfolded state to the 0° folded state, thereby realizing self-limitation 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 lever arm can be increased, which is helpful for the user to achieve the effect of saving effort in opening the door.

[0044] When the user has finished taking the item, during the closing process of the door body 220, the door handle 100 is suspended at 90°, which is convenient for closing the door and avoids the risk of pinching the hand when closing the door. When the door body 220 is closed to contact the cabinet opening, the cabinet opening pushes the upper end of the slider 53 upward, and the lower end of the slider 53 is subjected to the upward force applied by the cabinet opening. At this time, the movable component 50 moves up to the second limiting portion 51 and disengages from the first limiting portion 2. In this way, the gripping portion 20 can rotate relative to the mounting seat 10 / 10'. Therefore, under the action of the torsion spring 30, the door handle 100 is restored from the 90° unfolded state to the closed state. Figure 8 The 0° folded state shown is not easily touched by users, which provides a high user experience, occupies little space, and increases the packing volume during transportation.

[0045] The door handle 100 of this embodiment does not require deliberate human operation. The door handle 100 can be opened or closed by 90° when the door body 220 is opened, and while the door body 220 is open, the door handle 100 can hover at 90° until the door body 220 is closed.

[0046] like Figures 5 to 13 As shown, in this embodiment, the moving assembly 50 further includes an elastic member, which is specifically a spring 54. The stop block 52 has a hollow area (not shown). The spring 54 extends into the hollow area and partially extends out of the hollow area to abut against the mounting seat 10'. Specifically, a guide column 13 is formed on the inner side wall of the top surface of the mounting seat 10', and the part of the spring 54 extending out of the hollow area is sleeved on the guide column 13. When the door body 220 is closed, the upward force of the cabinet opening on the lower end of the slider 53 is transmitted to the spring 54, so that the spring 54 is compressed; when the door body 220 is opened by using the door handle 100, that is, when the upward force acting on the moving assembly 50 is eliminated, the stop block 52 and the slider 53 can be quickly moved downward by the elastic restoring force of the spring 54, and the stop block 52 and the slider 53 are kept stably limited in the mounting seat 10' after moving downward.

[0047] like Figure 6 As shown, in order to install the mounting base 10 on the door body 220, a connecting hole 11 and a positioning column 12 are formed on the surface of the mounting base 10 that contacts the door body 220, and a screw passes through the connecting hole 11 from the inside of the mounting base 10 to connect with the connecting hole on the door body 220, and the positioning column 12 is used to assist in positioning the door handle 100; and a connecting hole 11' and a positioning column 12' are formed on the surface of the mounting base 10' that contacts the door body 220, and a screw passes through the connecting hole 11' from the inside of the mounting base 10' to connect with the connecting hole on the door body 220, and the positioning column 12' is used to assist in positioning the door handle 100.

[0048] Embodiment 2

[0049] The present embodiment relates to a horizontal refrigerator 200, comprising a cabinet body 210, a door body 220 for opening and closing the cabinet opening of the cabinet body 210, and a door handle. The door handle may be a door handle 100. A force applying portion (not shown) is formed on the cabinet body 210, which applies an upward force to the movable assembly 50 when the door body 220 is closed, so that the movable assembly moves upward. The structure of the door handle 100 is shown in FIG. Figures 2 to 7 As described above, no further elaboration is given here.

[0050] In this embodiment, the upward force applied to the movable component 50 can be a component on the cabinet body 210, which can be a cabinet opening, or any other component provided on the cabinet body 210, as long as the movable component 50 can be supported and moved upward to the second limit portion 51 and the first limit portion 21 to disengage from the limit when the door body 220 is closed.

[0051] Figures 8 to 13 Three states of the door handle 100 between the first limiting portion 21 and the second limiting portion 51 on the horizontal refrigerator 200 are shown.

[0052] Figure 8 and Fig. 9 The figure shows the state of the first limiting portion 21 and the second limiting portion 51 when the door body 220 is closed and the door handle 100 is in a folded state. At this time, the first limiting portion 21 and the second limiting portion 51 are out of limit, and the grip portion 20 can rotate relative to the mounting seat 10 / 10'. The first limiting surface 211 and the second limiting surface 511 are in a vertical relationship, the second limiting surface 511 is located above the first limiting surface 211, and the second limiting portion 51 is located on the side of the first limiting portion 21 close to the door body 220.

[0053] Fig.10 and Fig.11 The figure shows the state of the first limiting portion 21 and the second limiting portion 51 when the door body 220 is closed and the door handle 100 is in the unfolded state. At this time, the first limiting portion 21 and the second limiting portion 51 are out of the limit position, and although the grip portion 20 is in the 90° unfolded state, the torsion spring 30 has a tendency to return to the natural state. The first limiting surface 211 and the second limiting surface 511 are parallel to each other.

[0054] Fig.12 and Fig.13 The figure shows the state of the first limit portion 21 and the second limit portion 51 when the door body 220 is open and the door handle 100 is in the unfolded state. At this time, the movable assembly 50 moves down to the second limit portion 51 to limit the first limit portion 21, so that the second limit portion 51 drops to the bottom of the rotating shaft 40' or is on the same horizontal plane with the rotating shaft 40', avoiding the first limit portion 21 from rotating around the rotating shaft 40' toward the door handle at 0°, and realizing the door handle hovering at 90°, which is convenient for closing the door and avoids pinching the hand when closing the door.

[0055] After taking out items from the bedroom refrigerator 200, when the door body 220 contacts the cabinet opening, the movable assembly 50 is lifted by the upward force, so that the door handle returns to the Fig.10 The state shown in FIG. 1 , and then under the action of the torsion spring 30, Fig.10 The status shown is restored to Figure 8 The state shown realizes the switching of the door handle 100 from the unfolded state to the folded state without unnecessary human operation, thereby improving the user experience and satisfying the effect of folding the door handle 100 when not in use to reduce the occupied space, and unfolding to assist the door when used to open the door body 220.

[0056] The front edge of the door body 220 is an arc-shaped edge. Correspondingly, the shape of the portion of the mounting seat 10 / 10 ′ that contacts the door body 220 is also an arc-shaped shape, which facilitates the tight installation of the door handle 100 / 100 ′ and the front edge of the door body 220 .

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
