Description

Technical Field

[0001] The utility model relates to the technical field of door bolts, in particular to a snap-on door bolt. Background Art

[0002] In modern building and home security, bolts are crucial components for ensuring the enclosure and safety of spaces. Their design and installation quality directly impact the user experience and safety. As a common door lock type, snap-on bolts are widely used on various door panels due to their simple structure, convenient operation, and affordable cost.

[0003] Conventionally, a snap-on bolt is arranged between a door frame and a door leaf, or between two door leaves, and is located indoors. Therefore, the bolt is locked indoors to lock the door leaf. Structurally, the snap-on bolt includes a fixing seat and a lock catch. The lock catch can be rotatably arranged on the door leaf, and the fixing seat is fixedly arranged on another door leaf or this door frame. The fixing seat is provided with a lock groove, and the lock catch can be rotated and buckled in the lock groove to achieve the effect of locking the door.

[0004] However, installation position offset is one of the common problems in snap-on door bolts. It refers to the inaccurate relative position between the lock and the fixing seat (usually installed on another door leaf or door frame), which makes the lock unable to buckle into the buckle groove smoothly. This problem usually stems from multiple aspects: First, the measurement work before installation may not be accurate enough, resulting in deviations from the preset installation position; secondly, the actual installation position of the lock and the fixing seat may not match the preset position due to improper operation, insufficient technical level or material deformation during the installation process; in addition, during long-term use, changes in environmental factors (such as fluctuations in temperature and humidity, external force impact, etc.) may also cause slight deformations of components such as door leaves and door frames, further aggravating the offset of the installation position. In view of this, the inventor has been tirelessly conducting research and improvements. After many tests and improvements, the snap-on door bolt of this invention was finally produced. Utility Model Content

[0005] The purpose of the utility model is to provide a snap-on door bolt, the snap-on portion of which can be properly adjusted to the position of the corresponding snap-on groove to ensure that the relative position between the two is accurate, and the adjustment is simple and convenient.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A snap-on door bolt includes a mounting seat, a rotating arm rotatably arranged on the mounting seat, the rotating arm is provided with a buckling portion, a fixed seat is provided in the rotation direction of the rotating arm, so that the fixed seat is provided with a buckling groove, the rotating arm rotates clockwise or counterclockwise, the buckling groove is buckled with the buckling portion, the rotating arm is provided with an adjustment channel along its length direction, the buckling portion is slidably arranged in the adjustment channel, and an adjustment component is provided between the adjustment channel and the buckling portion.

[0008] By adopting the above technical solution and setting the adjustment component, the buckle part can be flexibly slid and adjusted in the adjustment channel. The adjustment makes the position of the buckle part and the buckle groove relatively accurate, which can cope with the installation position deviation caused by various situations and greatly improve the practicality of the door bolt.

[0009] It is further configured as follows: the adjusting component includes a pair of sliding channels formed in the buckling part, each sliding channel is slidably provided with a locking block, a locking groove is opened in the adjusting channel and several pairs are arranged at intervals along the length direction of the adjusting channel, a linkage structure that controls the two locking blocks to enter the corresponding locking grooves respectively, and a contraction spring that linkage controls the two locking blocks to disengage from the locking grooves.

[0010] By adopting the above-mentioned technical solution and setting up the adjustment component, a stack of sliding channels is provided on the buckling part, and a slidable locking block is provided, and in cooperation with a plurality of pairs of locking grooves spaced along the length direction in the adjustment channel, precise positioning of the fastener part in the adjustment channel is achieved. When the locking block enters the corresponding locking groove under the control of the linkage structure, it can firmly lock the position of the buckling part to ensure its accurate docking with the buckling groove. The addition of the contraction spring provides an automatic reset mechanism for the locking block. When the position of the buckling part needs to be adjusted, the contraction spring can automatically drive the locking block out of the locking groove, so that the buckling part can slide smoothly in the adjustment channel. This automatic release function reduces the operator's manual operation and improves the adjustment fluency.

[0011] It is further configured as follows: the linkage structure includes a connecting block located between a pair of locking blocks and connected to each locking block, an inner spiral groove with an inward contraction formed between the two connecting blocks, and a bolt threadedly connected to the two inner spiral grooves.

[0012] By adopting the above technical solution and setting up the linkage structure, when the bolt rotates into the inner spiral groove, the two locking blocks are pushed by the bolt, causing the two locking blocks to move away from each other and enter the corresponding locking grooves. When the bolt is rotated out of the inner spiral groove, the two locking blocks are pulled by the contraction spring, causing the two locking blocks to move toward each other and disengage from the locking grooves. The operator can control the two locking blocks to enter or disengage from the locking grooves at the same time by simply rotating the bolt. This one-button or simple operation design greatly improves the convenience and efficiency of use. BRIEF DESCRIPTION OF THE DRAWINGS
