Figure 2 As shown, the locking portion 1 includes a lifting portion 101 connected to the unlocking portion 2 and a locking portion 102 connected to the lifting portion 101, the hook structure 3 is connected to the locking portion 102, and the side wall of the lifting portion 101 is provided with a baffle 5, the length of the baffle 5 is smaller than the length of the locking portion 102, and the upper surface of the baffle 5 is lower than the lower surface of the locking portion 102.

[0026] The present embodiment does not make any specific limitation on the material of the two-way docking hook. Depending on the specific application scenario, it can be made of steel, iron or plastic, etc., all of which are within the scope of protection of the present application. The connection relationship between the unlocking portion, the locking portion and the hook structure of the present embodiment includes but is not limited to one-piece molding, or each component can be manufactured separately and then fixedly connected together, such as welding, etc. As long as the connection method can play the same role, it is within the scope of protection of the present application. Similarly, the connection relationship between the lifting portion, the locking portion and the baffle is not limited to one-piece molding, and also includes manufacturing each component separately and then fixing it together according to the above-defined positional relationship. The hand-pull portion includes but is not limited to Figure 1 The pull ring shown may also be a pull rope or other structure. As long as it is used by the operator to hold and pull the unlocking part downward, it is within the protection scope of this application. The unlocking part may be linear or Figure 1The curved shape shown or other shapes that can achieve the purpose of this embodiment are within the scope of protection of this application; the use of the two-way docking hook disclosed in this embodiment is not limited to the field of hangers in the automotive field, but can also be applied to other fields; Working principle: When in use, the two-way docking hook can be set at both ends of the device to be connected (such as a hanger), such as Figure 7 As shown, when the hook structure of the two-way docking hook A of the device to be connected a is inserted into one end of the device to be connected b, the two-way docking hook B on the device to be connected b is also inserted into the device to be connected a. At this time, the hook structure of the two-way docking hook A of the device to be connected a is buckled with the horizontal bar in the device to be connected b, and at the same time, the hook structure of the two-way docking hook B of the device to be connected b is buckled with the horizontal bar in the device to be connected a, and the two devices to be connected are locked with each other. When unlocking is required, the hand-pull portion of the two-way docking hook A on any one of the devices to be connected (such as the device to be connected a) is pulled to disengage the two-way docking hook A from the horizontal bar in the device to be connected b, and at the same time, the baffle on the two-way docking hook A also moves accordingly, and the baffle on the two-way docking hook A The baffle lifts the engaging portion of the two-way docking hook B in the device b to be connected, and the engaging portion of the two-way docking hook B drives the entire locking portion of the two-way docking hook B to be lifted upward. Therefore, the two-way docking hook B is disengaged from the cross bar in the device a to be connected, and unlocking is completed at the same time. The present invention arranges a baffle on the side wall of the lifting portion, and limits the length of the baffle to be less than the length of the engaging portion, and the upper surface of the baffle is lower than the lower surface of the engaging portion. The two-way docking hooks can be installed at both ends of the hanger. When in use, there is no need to adjust the direction of the hanger to lock the two devices to be connected, and unlocking can be completed by pulling only one hand-pull portion. The structure is very simple, the conception is ingenious, the cost is low, the operation is convenient, a lot of manpower is saved, and the difficult problems in the industry are overcome.

[0027] In some embodiments, the angle α between the locking portion 1 and the unlocking portion 2 meets 90°≤α<180°.

[0028] This embodiment reduces the difficulty of pulling the hand-pulling part by limiting the angle α between the locking part 1 and the unlocking part 2. After many tests, it was found that when α is less than 90°, the locking part needs to be lifted upward to complete the unlocking, which is inconvenient for the staff to operate.

[0029] In certain embodiments, the angle α between the locking portion (1) and the unlocking portion (2) satisfies 120°≤α<150°.

[0030] This embodiment further limits the angle α between the locking portion 1 and the unlocking portion 2, so as to further reduce the difficulty of pulling the hand-pulling portion. After many tests, it is found that when 120°≤α<150°, the operation of the staff is most labor-saving.

[0031] In certain embodiments, such as Figure 1As shown, the baffle 5 is perpendicular to the side wall of the lifting portion 101; after many tests, it was found that when the baffle is vertically connected to the side wall of the lifting portion, the contact area is the largest and the effect is the best.

[0032] In certain embodiments, such as Figure 3 As shown, a through hole 6 is provided at the junction of the locking portion 1 and the unlocking portion 2 .

[0033] This embodiment facilitates installation by providing a through hole. When the two-way docking hook needs to be installed in a hanger, the fixed shaft in the hanger can be passed through the through hole to fix the two-way docking hook on the hanger.

[0034] In certain embodiments, such as Figure 4 As shown, a connecting rod 7 is provided at the junction of the locking portion 1 and the unlocking portion 2 .

[0035] This embodiment facilitates installation by providing a connecting rod. When the two-way docking hook needs to be installed in a hanger, two grooves can be opened on the inner wall of the hanger. The two ends of the connecting rod can be fixed in the grooves to fix the connecting rod hook on the hanger.

[0036] This embodiment provides a hanger with a two-way docking hook, such as Figure 5 and Figure 8 As shown, the hanger includes a hanger body 8 and a two-way docking hook, and the two-way docking hook is arranged at both ends of the horizontal mounting portion 9 of the hanger body 8, as shown in FIG. Figure 6 As shown, hook mounting parts 10 are provided at both ends of the horizontal mounting part 9, and a mounting opening 11 is provided at one end of the hook mounting part 10 away from the horizontal mounting part 9, and the unlocking part 2 of the two-way docking hook extends into the mounting opening 11, and a fixed shaft 12 is horizontally provided on the inner side wall of the hook mounting part 10, and the two-way docking hook is rotatably connected to the hook mounting part 10 through the fixed shaft 12, and an opening 13 for the unlocking part 2 to pass through is opened at the bottom end of the hook mounting part 10, and a horizontal bar 14 cooperating with the hook structure 3 is also provided in the mounting opening 11.

[0037] Among them, the hook mounting part can be integrally formed with the transverse mounting part, or it can be made separately and then connected to the transverse mounting part. A plurality of hooks for hanging parts are arranged on the lower surface of the transverse mounting part. The shape and number of the hooks can be adjusted according to actual needs. The embodiment does not make specific limitations on it. As long as the hooks can be used to hang parts, any hook can be used. The fixed shaft is a one-shaft mounted structure for passing through the two-way docking hook so that the two-way docking hook can rotate around the fixed shaft. The cross bar 14 and the fixed shaft 12 in this embodiment are combined into one. Of course, the cross bar 14 can also be set independently of the fixed shaft. When the fixed shaft is used as a cross bar at the same time, one component can be saved, the structure is simpler, and the cost can be reduced at the same time. This embodiment provides a specific implementation method of applying the two-way docking hook to a hanger. When in use, there is no need to adjust the direction of the hanger, and the unlocking can be completed by pulling only a hand-pull part, saving manpower.

[0038] In some embodiments, the width of the hook mounting portion 10 is greater than the sum of the width of the lifting portion 101 and the width of the baffle 5 .

[0039] In some embodiments, twice the distance between the fixed shaft 12 and the open end of the mounting opening 11 is smaller than the distance between the fixed shaft 12 and the hook structure 3 .

[0040] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
