TECHNICAL FIELD
[0001] The utility model relates to door lock bolt technology field, concretely is a kind of oblique bolt structure. BACKGROUND
[0002] There are many classifications of door locks, and the requirements for door locks are different in various occasions. Ordinary families usually use anti-theft door locks, which are high in safety and relatively inexpensive. Door locks with door body locking function usually have upper locking members and lower locking members in addition to the oblique bolt and the square tongue. The oblique bolt in the prior art usually includes an integrally connected oblique bolt part and a lock bar part. The oblique bolt part is used to insert into the lock hole of the door frame, and the lock bar part is used to slideably connect with the sliding seat sleeve inside the door lock, to guide the extension or contraction of the oblique bolt part. During daily use, the lock bar part also bears the relative impact force between the door body and the door frame. Since the oblique bolt part and the lock bar part are usually made of zinc alloy material in one piece, the relatively small cross-sectional area of the lock bar part is prone to bending or breaking after long-term use, resulting in a relatively low service life. Therefore, in order to solve the above problems, the present application provides a split type oblique bolt structure. SUMMARY
[0003] The utility model aims at providing an oblique bolt structure to solve the problems raised in the background art.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0005] An oblique bolt structure includes an oblique bolt head and a slide bar part. A plug-in slot is formed in the side wall of the oblique bolt head, and the end of the slide bar part is plugged into the plug-in slot. The slide bar part is fixedly connected to the oblique bolt head by a fastener.
[0006] Preferably, the oblique bolt head is made of metal material, and the slide bar part is made of aluminum alloy material.
[0007] Preferably, the fastener is a fastening pin shaft. A slide bar insertion hole is formed in one end of the slide bar part that extends into the plug-in slot. A bolt insertion hole is formed in the oblique bolt head for communication with the plug-in slot. The fastening pin shaft is simultaneously plugged into the bolt insertion hole and the slide bar insertion hole.
[0008] Preferably, slide bar guide grooves are further provided on both sides of the slide bar part to facilitate flexible sliding of the slide bar part.
[0009] Preferably, an axle body mounting hole for plugging in a drive shaft is further formed in the end of the slide bar part away from the oblique bolt head.
[0010] Preferably, bolt guide grooves are further provided on both sides of the oblique bolt head to facilitate flexible sliding of the oblique bolt head.
[0011] Compared with the prior art, the utility model has the advantages that: the utility model is assembled by adopting the split type structure, the slide strip part which is the guiding force receiving component is made of metal material which has relatively better strength and toughness, the production cost is not obviously increased, and the service life of the whole latch tongue is improved.
