[0028] Example

[0029] like Figure 1 - Figure 5 The utility model provides an aircraft luggage compartment door lock structure, which mainly includes a compartment body 1, a compartment door 2, a door lock assembly 3 and a locking assembly 4.

[0030] The box body 1 is installed on the upper part of both sides of the cabin of the aircraft and is used to store the luggage of passengers. An opening is reserved on one side of the box body 1 facing the cabin corridor.

[0031] The upper edge of the door 2 is rotatably connected to the upper edge of the opening to form a flip-up suitcase.

[0032] The locking function between the box body 1 and the box door 2 is achieved through the door lock assembly 3 and the locking assembly 4.

[0033] The door lock assembly 3 includes a latch 31 and a latch cover 32. The two latches 31 are fixed on the lower edge of the opening. A clearance groove is provided on the latch cover 32. When the latch cover 32 covers the lower edge of the opening, the latch 31 passes through the clearance groove and is exposed to the outside of the latch cover 32 to facilitate connection with the locking assembly 4.

[0034] The locking assembly 4 includes a lock seat 41, a handle 42, a rotating shaft 43, a cam 44, a lock hook 45, a handle spring 46, and a lock hook spring 47. The linkage design between the handle 42 and the lock hook 45 is mainly to prevent the lock hook 45 from being linked with the handle 42 when the box door 2 is closed, thereby preventing the handle 42 from popping out.

[0035] Specifically, the lock seat 41 is detachably connected to the lower edge side of the door 2 by bolt fasteners, and the lock seat 41 and the handle 42 are elastically rotatably connected by a handle spring 46. A groove 1 is provided on the corresponding ends of the lock seat 41 and the handle 42, and the two ends of the handle spring 46 are respectively stuck in the groove 1 of the lock seat 41 and the handle 42; when the handle 42 is rotated outward relative to the lock seat 41, the handle spring 46 is pulled, and when the force applied to the handle 42 is removed, the handle spring 46 drives the handle 42 to reset, thereby realizing the self-closing of the handle 42.

[0036] Preferably, when the handle 42 is closed, the handle 42 is pulled by the handle spring 46 and rotates and fits onto the lock seat 41 , a space is reserved between the lock seat 41 and the handle 42 for the user to insert his fingers to pick up the handle 42 .

[0037] The rotating shaft 43 includes two sections, one is a cylindrical section and the other is a prismatic section. The two sections are integrally formed and fixed to each other. The cylindrical section passes through the handle spring 46 to improve the stability of the position of the handle spring 46. The two ends of the prismatic section are respectively provided with a cam 44 and a lock hook 45. The edges of the prism enable the rotating shaft 43, the cam 44 and the lock hook 45 to rotate synchronously.

[0038] The rotating shaft 43 is horizontally rotatably connected to the lock base 41, the cam 44 and the lock hook 45 are respectively located on the inner and outer sides of the lock base 41, and both ends of the handle 42 are provided with a card slot. A card block is fixed on the cam 44, and the length of the card slot is greater than the length of the card block. The card block is placed in the card slot. In this way, the card block can move freely in the card slot until the card block hits the side wall of the card slot, which allows the cam 44 and the handle 42 to produce a joint movement.

[0039] Among them, the lock hook 45 and the lock seat 41 are elastically rotatably connected by a lock hook spring 47, that is, a groove 2 is provided on the lock hook 45 and the lock seat 41, and the two ends of the lock hook spring 47 are respectively clamped in the corresponding groove 2, and the prism section is penetrated in the lock hook spring 47 to improve the stability of the lock hook spring 47. When the lock hook 45 rotates upward, the lock hook 45 leaves the latch 31. When the external force on the lock hook 45 is withdrawn, the lock hook spring 47 drives the lock hook 45 to reset, allowing the lock hook 45 to rotate inward and buckle the latch 31 to achieve the locking purpose.

[0040] It should be noted that the latch 31 is located on the moving path of the lock hook 45. When the top of the lock hook 45 contacts the latch 31, the top of the lock hook 45 and the latch 31 will slide relative to each other, prompting the lock hook 45 to rotate upward to further lock the latch 31.

[0041] Here is a brief description of the working principle of the locking assembly 4:

[0042] In the stage of opening the door 2: the passenger buckles the handle 42 to drive the handle 42 to rotate. At this time, the card block and one side wall of the card slot are in contact. Therefore, the handle 42 can drive the lock hook 45 to rotate upward through the rotating shaft 43 and the cam 44 at the moment of rotation. The lock hook 45 and the latch 31 are separated, so that the door 2 can be opened easily.

[0043] When closing the door 2, the handle 42 retracts into the lock seat 41 under the reset action of the handle spring 46, and the passenger presses the outside of the handle 42 with his hand and presses it downward to close the door 2. During this process, when the lock hook 45 contacts the latch 31, the lock hook 45 will slide against the upper part of the latch 31, and the lock hook 45 rotates upward. At this time, the lock hook 45 drives the card block to rotate in the card slot through the rotating shaft 43 and the cam 44. During this process, the card block does not interfere with any side wall of the card slot, so there is no linkage relationship between the cam 44 and the handle 42. When the lock hook 45 rotates upward and buckles the latch 31, the handle 42 will not bounce up, thereby improving the protection of the passenger's hands.

[0044] In summary, compared with the prior art, this application has the following innovations and advantages:

[0045] 1. Both sides of the locking assembly 4 adopt a double spring structure. When the door 2 is closed, the lock hook 45 can be fastened with the latch 31 by itself without being linked with the handle 42, thereby improving the degree of protection for passengers and the convenience of use.

[0046] 2. The door lock adopts two symmetrical lock hooks 45, has a simple internal structure and reliable mechanical properties, and can be applied to various types of flip-up suitcases, not limited to the field of aircraft suitcases.

[0047] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

[0048] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;

[0049] Secondly: In the drawings of the embodiments disclosed in the present utility model, only the structures related to the embodiments disclosed in the present utility model are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0050] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
