Description

Technical Field

[0001] This utility model relates to the field of door lock hook technology, specifically to a car door lock hook structure. Background Technology

[0002] Car door locks use a latch or hook to engage with the door frame to lock the door. Hook-type door locks generally use a hook structure with a claw. The hook is connected to the door lock via a pivot. When the hook is rotated by the linkage mechanism, the claw rotates out of the door lock and hooks the door frame, thus completing the locking.

[0003] However, the claws in existing door locks wear down due to repeated locking and unlocking with the door frame over long-term use. If maintenance is required, the entire door lock needs to be replaced, which increases maintenance costs. Therefore, it is necessary to provide a split-type car door lock. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automotive door lock hook structure that allows the hook claw to be replaced separately, thereby reducing maintenance costs, in order to address the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car door lock hook structure, comprising a hook body, wherein the hook body is provided with a pivot hole, characterized in that: the hook body comprises a first hook body and a second hook body detachably connected to the first hook body, the second hook body is installed at the lower end of the first hook body, and a hook claw is installed between the first hook body and the second hook body through a detachable connection structure, wherein a locking groove is formed between the hook claw and the first hook body and the second hook body.

[0006] The above technical solution facilitates the assembly of the hook claw by separating the first hook body and the second hook body. The hook claw is fixed between the first hook body and the second hook body. At the same time, the detachable hook claw allows for individual replacement of the hook claw when it is worn, reducing maintenance costs. In addition, the locking groove formed between the hook claw and the first hook body and the second hook body can lock with the door frame.

[0007] A further feature of this invention is that: the first hook body has a first slot at one end near the hook claw, the second hook body has a second slot corresponding to the first slot, and when the second hook body is installed on the first hook body, the first slot and the second slot can form an installation groove, and the hook claw has an installation block at one end near the hook body, the installation block can be installed in the installation groove.

[0008] The above technical solution is adopted as follows: During the assembly process, after the mounting block of the hook claw is placed into the second slot of the second hook body, the first hook body and the second hook body are assembled. At this time, the mounting block is fixed in the mounting groove formed by the first slot and the second slot, thus completing the installation of the hook claw.

[0009] A further feature of this invention is that: limiting blocks are provided on both sides of the mounting block, and limiting grooves adapted to the limiting blocks are provided on both sides of the mounting groove.

[0010] The above technical solution is adopted: by setting the limiting block and the limiting groove, when the hook is assembled between the first hook body and the second hook body, the limiting block is located in the limiting groove, which can prevent the hook from falling off and improve the installation stability.

[0011] A further feature of this invention is that the upper and lower surfaces of the mounting block are provided with elongated protrusions, and the bottom of the first and second slots are provided with grooves that are adapted to the shape of the elongated protrusions.

[0012] The above technical solution is adopted: by setting the long strip protrusion and the groove, when the hook is assembled between the first hook body and the second hook body, the long strip protrusion and the groove can engage with each other, further improving the installation firmness between the hook and the first hook body and the second hook body.

[0013] A further feature of this invention is that at least two sets of positioning blocks are provided opposite each other at the edge of the upper end face of the second hook body, and a positioning groove is provided at the lower end face of the first hook body corresponding to the positioning blocks.

[0014] The above technical solution, through the setting of positioning blocks and positioning slots, plays a positioning role before the first hook body and the second hook body are installed, eliminating the need for workers to find suitable positions for assembly, making assembly easier and improving assembly efficiency.

[0015] A further feature of this invention is that the first hook body has a plurality of first mounting holes along its outer edge, the second hook body has a second mounting hole corresponding to the first mounting holes along its outer edge, and a fastener is provided between the first mounting holes and the second mounting holes.

[0016] The above technical solution is adopted as follows: by setting the first mounting hole and the second mounting hole, the first hook body and the second hook body are aligned by the positioning block and the positioning groove, so that the first mounting hole and the second mounting hole are connected, and then the first hook body and the second hook body are assembled by fasteners to complete the installation.

Other structures can be referred to with ordinary design. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of this utility model, they are protected by patent law.

[0025] like Figure 1-5 The car door lock hook structure shown includes a hook body 1, on which a pivot hole 11 is provided. The pivot hole 11 is used to install a pivot, so that the lock hook can rotate around the pivot. The hook body 1 includes a first hook body 12 and a second hook body 13 detachable from the first hook body 12. The second hook body 13 is installed at the lower end of the first hook body 12. A hook claw 2 is installed between the first hook body 12 and the second hook body 13 through a detachable connection structure.
