Description

Technical Field

[0001] This utility model relates to the field of locking device technology, specifically to a novel self-locking carriage door latch. Background Technology

[0002] Existing trucks all have a cargo compartment at the rear, with the compartment door hinged to the main body and locked in place by a latching device.

[0003] Traditional locking devices, once the truck bed doors are locked, can easily loosen unexpectedly when the truck is in motion due to external forces or vibrations from the vehicle. This can cause the truck bed doors to open accidentally during travel, posing a safety hazard.

[0004] Therefore, a novel self-locking carriage door latch is proposed to address the current shortcomings. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a new type of self-locking carriage door latch.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a new type of self-locking carriage door latch: including a base, a handle, a latch body and a self-locking frame;

[0007] The base has a cuboid structure, the handle is rotatably connected to one end of the base, and the other end of the base is provided with a locking hook;

[0008] The self-locking frame has a U-shaped structure and its open end is rotatably connected to the front of the handle. One end of the locking body is movably disposed inside the self-locking frame. The end of the locking body is provided with a limiting member that slides with the self-locking frame. The locking body is fitted with springs at both ends that abut against the self-locking frame and the limiting member, respectively.

[0023] To make the objectives, technical solutions, and advantages of the utility model embodiments clearer, the technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The components of the utility model embodiments described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0024] In the description of the embodiments of the utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of the utility model embodiments, "a plurality of" means at least two.

[0027] In the description of the embodiments of the utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0028] Combined with appendix Figure 1-5 As shown, a novel self-locking carriage door latch includes a base 1, a handle 2, a latch body 3, and a self-locking frame 4. In this embodiment, the base 1 is made of metal and is fixedly mounted horizontally on the carriage door.

[0029] Specifically, the base 1 has a cuboid structure, which facilitates the fixed connection between the base 1 and the carriage door. At the same time, its rectangular structure facilitates the installation of the carriage door latch component and ensures the cooperative use of the components.

[0030] The handle 2 is rotatably connected to one end of the base 1. The handle 2 is located outside the base 1 and is linearly arranged with the base 1. The handle 2 can be rotated along the length of the base 1.

[0031] To improve the comfort of operating the car door latch, a rubber sleeve 11 is provided at the other end of the handle 2. The bottom of the rubber sleeve 11 is provided with a groove that fits the hand, making it easier for the user to grip the handle 2 and rotate it to open and close the car door latch.

[0032] The other part of the base 1 is provided with a locking hook 5. Specifically, the locking hook 5 is in the shape of a "7" and its opening faces away from the handle 2.

[0033] The locking hook 5 is fixedly connected to the base 1. In actual use, the locking hook 5 is fixedly connected to the fastener set on the vehicle body through the cooperation of the fastener and the locking hook 5, as well as the cooperation of the locking body 3 and the locking hook 5, so as to lock the car door.

[0034] Meanwhile, the "7" shape of the locking hook 5 facilitates the cooperation between the fastener and the locking hook 5, and ensures the secure attachment between the locking body 3 and the locking hook 5, preventing the carriage door from accidentally opening during travel due to the separation between the locking body 3 and the locking hook 5.

[0035] The self-locking frame 4 has a U-shaped structure and its open end is rotatably connected to the front of the handle 2. In specific implementation, the self-locking frame 4 is movably disposed between the handle 2 and the locking hook 5.

[0036] Specifically, the front part of the handle 2 is located inside the opening end of the self-locking frame 4 and is rotatably connected to the self-locking frame 4. During use, the self-locking frame 4 can be moved and set under the drive of the handle 2, so as to facilitate the hanging of the locking body 3 and the locking hook 5.

[0037] One end of the locking body 3 is movably disposed within the self-locking frame 4, and the locking body 3 can move along the length direction of the self-locking frame 4, that is, along the length direction of the base 1.

[0038] The locking body 3 is provided with a limiting member 6 at its end, which slides with the self-locking frame 4, and the self-locking frame 4 is provided with a sliding hole 9 that cooperates with the limiting member 6.

[0039] During implementation, the limiting member 6 slides with the self-locking frame 4 through the sliding hole 9, which can ensure the stability of the locking body 3 in the self-locking frame 4. At the same time, it can prevent the locking body 3 from separating from the locking hook 5 due to the shaking of the locking body 3.

[0040] The locking body 3 is fitted with springs 7 at both ends that abut against the self-locking frame 4 and the limiting member 6 respectively, and the other end of the locking body 3 is provided with a locking hole 8 that cooperates with the locking hook 5.

[0041] When the door latch is in the open state, the spring 7 is in the initial state. At this time, under the action of the spring 7, the end of the latch body 3 moves to the end of the self-locking frame 4 near the handle 2.

[0042] When it is necessary to lock the car door latch, the fastener on the car body is engaged with the locking hook 5, the handle 2 is turned upward, the latch hole 8 at the end of the latch body 3 is hooked with the locking hook 5, and then the handle 4 is pressed downward. During the downward pressing of the handle 4, the limiting member 6 connected to the latch body 3 moves toward the end of the self-locking frame 4 away from the handle 4. At this time, the spring 7 is in a compressed state. When the handle 4 is pressed down to a horizontal state, under the action of the spring 7, the latch body 3 and the self-locking frame 4 are in a tensile state, realizing the self-locking restriction of the car door latch.

[0043] Furthermore, the base 1 is provided with side plates 10 on both sides that cooperate with the self-locking frame 4. When the car door latch locks the car door, the self-locking frame 4 contacts the base 1. The side plates 10 can prevent the self-locking frame 4 from shifting, thus ensuring the stability of the car door latch in the locked state.

[0044] In a specific implementation of this utility model, the fasteners on the vehicle body are matched with the locking hook 5, and then the locking hook 5 is attached to the locking hole 8 at the end of the locking body 3. Then the handle is pressed down to lock the car door.

[0045] Specifically, after the handle 4 is pressed down to a horizontal position, the spring 7 tightens the latch body 3 and the self-locking frame 4, thereby achieving the self-locking restriction of the car door latch. This also prevents the handle 4 from being accidentally released after being subjected to vibration or external force, thus ensuring reliable locking of the car door.

[0046] When opening the car door latch, simply hold the handle 4 and pull it upwards. As the handle 4 is pulled upwards, the spring 7 gradually returns to its initial state. At this time, the latch body 3 can be separated from the self-locking frame 4, and the car door latch can be opened.

[0047] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
