Description

A Length-adjustable Lock Cylinder
Technical field
The present invention relates to the technical field of locks, in particular to a length-adjustable lock cylinder.
Background technology
Currently, due to the different thickness of doors, the requirements for the length of the lock cylinder are different for both the external length and the internal length, which results in the lock cylinder mounted on the door having to be of different lengths so as to match the thickness of the door. Therefore, when manufacturing the lock cylinder, based on the actual thickness of the door on site, the lock cylinder must be customized again, and many lock cylinders of different lengths must be processed, which brings great inconveniences to manufacturers in organizing the production of lock cylinders. This has resulted in a wide variety of locks, leading to a waste of resources in production by manufacturers, increased costs, and inconvenience to vendors. When purchasing door locks, users are also prone to confusion in choosing the length of lock cylinders.
Chinese patent CN 201910076769.4 discloses a length-adjustable lock cylinder. A transmission channel is arranged in the lock cylinder; the said lock cylinder specifically comprises a rear lock body, a middle lock body, a front lock body, a shifting head and at least one first lengthened insertion piece; the said transmission channel sequentially passes through the rear lock body, the middle lock body, the first lengthened insertion piece and the front lock body; a transmission shaft, a left transmission barrel, a right transmission barrel, a first insertion piece transmission barrel and a lock liner are sequentially arranged in the transmission channel from left to right. However, based on the products it provides, there are still many problems. For example, after disassembly, it is found that many parts need to be pieced together, and it is difficult for consumers who are not technicians in the
field to identify how to mount them.
Chinese patent 201510082046.7 discloses a mortise-type telescopic lock, which comprises a lock head, wherein the lock head is provided with a mortise hole; the side surface of the lock head is extended with a front lock body through a slide rail device; an idle block corresponding to the lock cylinder is rotationally arranged on the front lock body; a key eye hole is arranged on the idle block; the key eye hole can rotate along with the idle block to be aligned with the key hole of the lock cylinder; and the structure is that the lock head is used by matching the slide rail device and the idle block at the front end of the lock head with a specific extension key. In this way, it is required to adapt different keys based on different extended lengths in the production process, which tremendously increases the production cost of the enterprise. Meanwhile, if the key is lost in the later period, it will not be possible to match the appropriate key in the normal key matching store.
Summary of the Invention
In this respect, the present invention provides a universal length-adjustable lock cylinder for anti-theft locks, which has adjustable lock body length, high safety, can be mounted on doors with different wall thicknesses as required and is convenient to adjust.
