Abstract
Description
Technical Field
[0001] This utility model relates to the field of door lock technology, and in particular to a door lock. Background Technology
[0002] Existing door lock structures are too complex, especially those used for temporary locking; none are simple in structure and easy to use.
[0003] Moreover, existing bolt locks can only be installed on parallel door frames or double doors, making it difficult to lock the door when the door frame or double door is not level. Utility Model Content
[0004] In view of the above situation, it is necessary to provide a door lock that solves at least one of the above problems.
[0005] A door lock includes a bolt, a first lock body, and a second lock body, which are arranged in parallel. The bolt includes a bolt body with its opening facing downward. The two ends of the bolt body are parallel and respectively disposed in the first and second lock bodies. One end of the bolt body passes through the first lock body and extends downward a predetermined distance to form a limiting structure at the end. The limiting structure is used to prevent one end of the bolt body from detaching from the first lock body.
[0006] This structure is simple and easy to install and use. It can be used for temporary door locking. When used on door frames with various angles or unevenness (double doors), it is only necessary to ensure that the first lock body and the second lock body are parallel, and the bolt can be inserted downward into the first lock body and the second lock body to achieve the purpose of locking and unlocking the door. It is applicable to more situations than existing door locks and can be used on left and right opening doors, top and bottom opening doors, sliding doors, uneven doors, and 90-degree doors, etc. Attached Figure Description

[0018] Please see Figure 1-4 A door lock according to an embodiment of the present invention includes a bolt, a first lock body 200, and a second lock body 300. The first lock body 200 and the second lock body 300 are arranged in parallel. The bolt includes a bolt body 100 with its opening facing downward. The two ends of the bolt body 100 are parallel and respectively disposed in the first lock body 200 and the second lock body 300. One end of the bolt body 100 passes through the first lock body 200 and extends downward by a predetermined distance, forming a limiting structure 110 at the end. The limiting structure 110 is used to prevent one end of the bolt body 100 from detaching from the first lock body 200.
[0019] In this embodiment, the first lock body 200 and the second lock body 300 are arranged in parallel, with the bolt 100 opening downwards. During installation, the two ends of the bolt 100 are aligned with the mounting holes on the first lock body 200 and the second lock body 300, respectively, and the bolt 100 is pushed into the first lock body 200 and the second lock body 300. If the first lock body 200 and the second lock body 300 are located on both sides of a double door or on a single door and a wall, the purpose of restricting the opening of the door can be achieved. If the door needs to be opened, simply remove one end of the bolt 100 from the second lock body 300, i.e., pull the bolt 100 up. If you continue to pull up until the limiting structure 110 abuts against the first lock body 200, the bolt 100 is restricted from being pulled up further, thus preventing the bolt 100 from detaching from the first lock body 200. This structure is simple, easy to install and use, and can be used for temporary door locking to prevent children from accidentally opening the door and causing accidents. (During installation and disassembly, the limiting structure 110 can be squeezed forcefully to pass through the first locking body 200, thereby achieving the purpose of installing and removing the bolt body 100.)
[0020] When the bolt 100 is installed in the first lock body 200, to close the door, simply turn the door so that the other end of the bolt 100 is aligned with the second lock body 300, drop the bolt 100 to connect the first lock body 200 and the second lock body 300, and the door will be locked.
[0021] The opening of the bolt body 100 and the arrangement of the first lock body 200 and the second lock body 300 are described here for ease of explanation based on one usage scenario. The opening of the bolt body 100 can also be to the left or to the right. In this case, it is only necessary to set the first lock body 200 and the second lock body 300 horizontally in correspondence. This derivative scheme is also within the scope of protection.
[0022] Based on the above structural description and usage instructions, it is entirely conceivable that when the door lock disclosed in this utility model is applied to door frames (double doors) with various angles or uneven surfaces, it is only necessary to ensure that the first lock body and the second lock body are parallel, and the bolt body can be inserted downward into the first lock body and the second lock body to achieve the purpose of locking and unlocking the door. The applicable situations are more numerous than those of existing door locks.
[0023] Specifically, the door lock disclosed in this utility model can be used on left and right opening doors, top and bottom opening doors, sliding doors, uneven doors, and 90-degree doors, etc.
[0024] In a preferred embodiment, the thrombus may be U-shaped.
[0025] The limiting structure 110 can be a square limiting block that extends outward.
[0026] The preset distance can be set according to actual needs.
[0027] In one embodiment, the first lock body 200 is provided with at least one set of first arched holes 210, one end of the bolt body 100 passes through one end of the first arched hole 210 to the other end and extends a preset distance, and the limiting structure 110 restricts one end of the bolt body 100 from disengaging from the first arched hole 210.
[0028] In this embodiment, by providing a first arched hole 210, a hole is formed between the first lock body 200 and the first arched hole 210 for the bolt body 100 to pass through. The first lock body 200 is provided with a notch corresponding to the position of the first arched hole 210, which makes it easier to install and remove the bolt body 100 when operating it with great force.
[0029] In one embodiment, the first lock body 200 is provided with two sets of first arched holes 210, the two sets of first arched holes 210 are respectively provided at both ends of the first lock body 200, and one end of the bolt body 100 passes through the two sets of first arched holes 210 in sequence and extends out a preset distance.
[0030] In this embodiment, by setting the first arched hole 210 into two sets, the bolt 100 is prevented from easily detaching from the first locking body 200, thus avoiding loss.
[0031] In one embodiment, a guide portion 220 is provided on the first lock body 200 between the two sets of first arched holes 210, and both sets of first arched holes 210 and guide portions 220 are located on the movement trajectory of the end of the bolt body 100.
[0032] In this embodiment, by providing the guide portion 220, the first arched hole 210 behind the bolt body 100 can be better aligned when the bolt body 100 is installed, forming a guide channel between the two arched holes.
[0033] In one embodiment, the guide portion 220 is provided with an opening extending along the length direction on the side opposite to the first arched hole 210.
[0034] In this embodiment, by providing an opening, it is not too difficult to install and remove the bolt 100.
[0035] In one embodiment, the first lock body 200 is provided with a plurality of screw holes.
[0036] In this embodiment, the first lock body 200 can be installed on a door or wall using screws through the screw holes.
[0037] In one embodiment, the second lock body 300 is provided with a plurality of screw holes.
[0038] In this embodiment, the second lock body 300 can be installed on a door or wall using screws through the screw holes.
[0039] In one embodiment, an I-shaped hole 230 is provided on the first lock body 200 between the two ends of the guide portion 220 and the corresponding first arched hole 210.
[0040] In this embodiment, by setting the I-shaped hole 230, material costs are saved, and the locking structure 110 on the bolt body 100 can be more easily disengaged from the first lock body 200 when the limiting structure 110 on the limiting structure 110 is rotated to a specific angle (the protrusion on the limiting structure 110 is aligned with the I-shaped hole 230).
[0041] In one embodiment, the second lock body 300 is provided with at least one set of second arched holes 310, and the other end of the bolt body 100 is at least partially located in the second arched holes 310.
[0042] In this embodiment, when the bolt 100 is in the locked state, at least part of the other end of the bolt 100 is located in the second arched hole 310, thereby restricting the bolt 100 from rotating to open the door.
[0043] In one embodiment, the second lock body 300 is provided with two sets of second arched holes 310, which are respectively provided at both ends of the second lock body 300. The other end of the bolt body 100 passes through the two sets of second arched holes 310 in sequence and is at least partially located in the lower second arched hole 310.
[0044] In this embodiment, when the bolt 100 is in the locked state, at least part of the other end of the bolt 100 is located in the second arched hole 310 below, further achieving the purpose of restricting the bolt 100 from rotating to open the door.
[0045] In one embodiment, the preset distance is greater than or equal to the distance between the two sets of the second arched holes 310.
[0046] In practice, the size of the preset distance can be varied according to the setting position of the second arched hole 310. It is best if the bolt 100 can be removed from the second lock body 300 after the bolt body 100 is pulled up, and the limiting structure 110 just touches the first arched hole 210 or has not yet touched the first arched hole 210.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
