Description

Technical Field

[0001] This utility model relates to the field of lock cylinders, and in particular to a split-type lock cylinder structure. Background Technology

[0002] Currently, lock bodies on the market include a zinc alloy die-cast lock cylinder structure and a copper lock chip installed on the lock cylinder structure. Lock cylinders produced by this structure use a large amount of copper material, and the copper material has low hardness, which generally results in high production costs and insufficient strength, and they are prone to wear.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a split lock cylinder structure, which adopts an assembly structure, resulting in a lock cylinder with low cost and high hardness.

[0005] To achieve the above objectives, this utility model provides a split lock cylinder structure, which includes a housing and a lock cylinder body. Both the housing and the lock cylinder body are made of stainless steel. The housing is a hollow cylindrical shape, and a first assembly port is opened on the shell wall of the housing. The lock cylinder body can be installed inside the housing through the first assembly port or removed from the housing through the first assembly port.

[0006] In one or more embodiments, the shell wall of the housing is provided with a second assembly port on the side opposite to the first assembly port, and the shape and size of the second assembly port are the same as those of the first assembly port.

[0007] In one or more embodiments, the lock cylinder body includes an upper structural piece, a lower structural piece, and a plurality of spacers. The plurality of spacers are evenly spaced in front and behind, and the upper and lower ends of the spacers are respectively connected to the upper structural piece and the lower structural piece. The spacers form a space for installing the lock chip, and the spacers have lock holes.

[0008] In one or more embodiments, the upper and lower ends of the partition are provided with slots, and the upper and lower structural pieces are provided with interlocking portions that are interference fit with the slots.

[0009] In one or more embodiments, the lock cylinder structure further includes a housing, which is placed inside the housing and secured with screws.

[0010] In one or more embodiments, the outer casing and housing have holes for screw connection, and the front side of the outer casing is provided with a cover plate, which has an opening corresponding to the lock hole.

[0011] Compared with the prior art, the advantages of this utility model are: the lock cylinder structure is a split structure consisting of a shell and a lock cylinder body. The lock cylinder body can be installed from the side of the shell. Compared with the traditional die-cast integrated structure, the production difficulty is reduced. In terms of materials, stainless steel can be selected to make the lock cylinder, which gives the lock cylinder better hardness and service life, and the production cost is also reduced.

[0013] Figure 2 This is an exploded view of the lock cylinder structure according to an embodiment of the present utility model. Detailed Implementation

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to Figure 1-2 This application provides a split-type lock cylinder structure, which includes a housing 1 and a lock cylinder body. The housing and lock cylinder body are made of stainless steel. The stainless steel housing and lock cylinder body are high in hardness, hard in texture, wear-resistant, waterproof and rustproof. The housing 1 is a hollow cylindrical shape. A first assembly port 2 is opened on the housing wall. The lock cylinder body can be installed inside the housing 1 through the first assembly port; or it can be removed from the housing through the first assembly port. The lock cylinder made with this split-type assembly structure has the advantages of lower production cost and greater durability compared with the traditional zinc alloy lock cylinder structure made by die casting.

[0016] The shell wall of the housing 1 is provided with a second assembly port 3 on the other side of the first assembly port. The shape and size of the second assembly port are the same as those of the first assembly port, so that the first assembly port and the second assembly port can be selected for assembly as needed during production.

[0017] The lock cylinder body includes an upper structural piece 4, a lower structural piece 5, and multiple spacers 6. The multiple spacers are evenly spaced front to back, and the upper and lower ends of the spacers 6 are connected to the upper structural piece 4 and the lower structural piece 5, respectively. The spacers form a space for installing the lock chip. The spacers have lock holes 7. With this structure, the upper structural piece, the lower structural piece, and the spacers can all be processed and stamped separately, and then automatically assembled later.

[0018] The upper and lower ends of the partition 6 are provided with slots 8, and the upper and lower structural pieces are provided with interlocking parts 9 that are interference fit with the slots. The front part is inserted into the slots for interference fit, so that each partition is assembled and fixed together with the upper and lower structural pieces to ensure the structural stability of the upper structural pieces, lower structural pieces and multiple partitions after assembly.

[0019] The lock cylinder structure also includes a housing 10, which is placed inside the housing and locked with screws. The housing is used to protect the housing and to be assembled on the door lock. The housing is preferably made of stainless steel. The housing 10 and the housing 1 have holes 11 for screw connection. The front side of the housing is provided with a cover plate 12, which has holes 13 that correspond to the lock holes. The screw fixing has the advantages of easy installation and disassembly.
