Embodiment Construction

[0012] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0013] like figure 1 As shown, a lock sleeve provided with a limiting component, the lock sleeve provided with a limiting component includes a lock sleeve body 1 and a lock cylinder accommodating hole 2 arranged on the lock sleeve body 1, one end of the lock cylinder accommodating hole 2 An annular limiting piece 3 is provided at the opening, and a pair of lock cylinder positioning slots 4 are provided on the inner wall of the lock cylinder receiving hole 2 .

[0014] The lock sleeve body 1 is in the shape of a racetrack as a whole, including a semicircular lock sleeve body at both ends and a rectangular lock sleeve body in the middle.

[0015] The lock s...

Abstract

The invention discloses a lock sleeve provided with a limiting component. The lock sleeve provided with the limiting component comprises a lock sleeve body and a lock cylinder containing hole formed in the lock sleeve body. An annular limiting piece is arranged at an opening in one end of the lock cylinder containing hole. A pair of lock cylinder positioning clamping grooves is formed in the inner wall of the lock cylinder containing hole. By arranging the annular limiting piece and the lock cylinder positioning clamping grooves on the lock cylinder containing hole, rotating and sliding of a lock cylinder in the lock sleeve provided with the limiting component can be effectively limited. Abrasion of the lock cylinder is reduced, and the service life of the lock cylinder is prolonged.

Description

technical field [0001] The invention relates to a locking sleeve provided with a limiting component. Background technique [0002] In the existing door lock structure, a lock sleeve provided with a limiting part is provided outside the lock core to protect it. Because the head of the lock core is generally cylindrical, the lock sleeve provided with the limiting part is generally an annular sleeve, and the lock core is placed inside the lock sleeve provided with the limiting part. However, as the use time increases, the lock core will rotate and slide relative to the lock sleeve provided with the limiting part, which will cause wear to the lock core and reduce the service life of the lock core. Contents of the invention [0003] The object of the present invention is to overcome the defects existing in the prior art, and provide a lock sleeve which fixes the lock cylinder firmly and is provided with a limiting part. [0004] In order to achieve the above object, the techn...
