Description

Technical Field

[0001] This utility model relates to the field of lock and building hardware technology, and in particular to a lock sleeve structure that is easy to install and position. Background Technology

[0002] A lock sleeve is an important component of a lock, primarily fitted over the lock cylinder. Its core functions are to fix the lock cylinder's position, guide its installation, protect it from external wear and impact, and help limit its rotation angle to ensure smooth key operation. Commonly found in doors, windows, furniture, and safes, it is a fundamental accessory in the lock and building hardware industry; therefore, a lock sleeve structure that facilitates easy installation and positioning is particularly needed.

[0003] However, existing lock sleeves require multiple manual alignment adjustments during installation, especially in door, window, or furniture assembly scenarios. Often, due to insufficient matching precision between the lock sleeve and the lock cylinder and mounting holes, workers have to repeatedly adjust and fix it, significantly extending the construction time. At the same time, most lock sleeves use an open design for the keyhole, allowing dust, oil, hair, and other dirt to easily penetrate into the keyhole during daily use. This dirt not only adheres to the lock cylinder pins or blades but is also carried deep into the lock when the key is inserted or removed. Over time, this increases the resistance to key rotation and may even cause pin jamming, lock cylinder blockage, and other malfunctions, affecting the lifespan and security of the lock to some extent. Utility Model Content

[0004] The purpose of this utility model is to provide a lock sleeve structure that is easy to install and position, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lock sleeve structure that is easy to install and position, comprising an all-steel outer shell, a steel paddle and a lock cylinder, wherein a lock hole is provided on one side surface of the lock cylinder, a fixing bolt hole is provided on one side surface of the all-steel outer shell, a tumbler groove is provided on one side surface of the all-steel outer shell, a limit groove is provided on one side surface of the all-steel outer shell, and a positioning mechanism is provided on the outer side surface of the all-steel outer shell; The positioning mechanism includes a connecting sleeve, which is inserted into the outer surface of the all-steel shell. A sliding block is fixedly connected to the inner surface of the connecting sleeve. A fixing plate is fixedly connected to one side surface of the connecting sleeve. A first mounting hole is opened on one side surface of the fixing plate. A fixing sleeve is inserted into the outer side of the fixing plate. A second mounting hole is opened on one side surface of the fixing sleeve. An annular groove is opened on the inner surface of the fixing sleeve. An annular component is rotatably connected to the inner surface of the annular groove. A protective shell is fixedly connected to the inner surface of the annular component. A brush assembly is provided on the inner surface of the protective shell.

[0006] Preferably, the brush set consists of two brushes of the same size, which are symmetrically distributed along the horizontal central axis of the annular component.

[0007] Preferably, the first mounting hole has two holes of the same size and is symmetrically distributed along the vertical central axis of the fixing piece, and the second mounting hole has two holes of the same size and is symmetrically distributed along the vertical central axis of the fixing sleeve. The first mounting hole and the second mounting hole have the same size.

[0008] Preferably, the limiting groove has two of the same size and is symmetrically distributed along the vertical central axis of the all-steel shell, and the sliding block has two of the same size and is symmetrically distributed along the vertical central axis of the connecting sleeve. The inner wall size of the limiting groove is adapted to the outer wall size of the sliding block.

[0009] Preferably, the inner wall size of the connecting sleeve is adapted to the outer wall size of the all-steel shell, and the cross-section of the sliding block is designed in a "T" shape.

[0010] Preferably, the inner dimensions of the fixing sleeve are adapted to the outer wall dimensions of the fixing piece, and the horizontal and vertical central axes of the protective shell, the annular part, the fixing sleeve, and the fixing piece coincide.

[0011] Preferably, the inner wall size of the annular groove is adapted to the outer wall size of the annular component, and the protective shell is provided in two identical sizes, which are symmetrically distributed along the transverse central axis of the annular component.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the lock sleeve structure that is easy to install and position, the double symmetrical brush group can actively clean the stains on the key surface before the key is inserted, and prevent the stains from being brought into the key hole. The protective shell can be flexibly opened and closed through the rotational cooperation of the annular part and the annular groove. When closed, it completely covers the key hole, effectively blocking the intrusion of external dust, oil and other impurities, reducing the problem of lock cylinder pin jamming and blockage, extending the service life of the lock, and improving the defect of traditional lock sleeves that "open key holes are easy to get dirty". With the precise fit of the "T"-shaped sliding block and the limiting groove, the connecting sleeve can quickly complete the initial positioning with the all-steel shell without repeated adjustments. At the same time, the holes of the fixing plate and the fixing sleeve are symmetrical and the same size, which can achieve quick alignment of the holes. Combined with the fixing bolt holes of the all-steel shell, the whole is fixed, which greatly shortens the installation time, solves the pain point of "repeated alignment" of traditional lock sleeves, and reduces the difficulty of manual operation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 This utility model provides a technical solution: a lock sleeve structure that is easy to install and position, including an all-steel outer shell 1, a black steel lever 2 and a lock cylinder 3. A lock hole 4 is opened on one side surface of the lock cylinder 3, a fixing bolt hole 5 is opened on one side surface of the all-steel outer shell 1, a tumbler groove 6 is opened on one side surface of the all-steel outer shell 1, a limit groove 7 is opened on one side surface of the all-steel outer shell 1, and a positioning mechanism 8 is provided on the outer side surface of the all-steel outer shell 1. The positioning mechanism 8 includes a connecting sleeve 801, which is inserted into the outer surface of the all-steel outer shell 1. A sliding block 802 is fixedly connected to the inner surface of the connecting sleeve 801. A fixing plate 803 is fixedly connected to one side surface of the connecting sleeve 801. A first mounting hole 804 is formed on one side surface of the fixing plate 803. A fixing sleeve 805 is inserted into the outer side of the fixing plate 803. A second mounting hole 806 is formed on one side surface of the fixing sleeve 805. An annular groove 807 is formed on the inner surface of the fixing sleeve 805. A ring-shaped component 808 is rotatably connected to the side surface of the ring-shaped component 808. A protective shell 809 is fixedly connected to the inner surface of the ring-shaped component 808. A brush assembly 810 is provided on the inner surface of the protective shell 809. Through the arrangement of the first mounting hole 804, the fixing sleeve 805, the second mounting hole 806, the annular groove 807, the ring-shaped component 808, the protective shell 809, and the brush assembly 810, in use, the connecting sleeve 801 is first aligned with the outer side of the all-steel shell 1, so that the two "T"-shaped sliding blocks 802 on the inner side of the connecting sleeve 801 are symmetrically distributed with two limiting blocks on the all-steel shell 1. With precise alignment of groove 7, utilizing the dimensional compatibility between sliding block 802 and limiting groove 7, connecting sleeve 801 is smoothly inserted into the all-steel outer shell 1 along limiting groove 7 to achieve positioning. Next, fixing sleeve 805 is fitted onto the outside of fixing piece 803. Because the inner dimensions of fixing sleeve 805 match the outer wall dimensions of fixing piece 803, and the two first mounting holes 804 on fixing piece 803 and the two second mounting holes 806 on fixing sleeve 805 are the same size and symmetrically distributed along the vertical central axis, the holes can be quickly aligned, and fixing is completed by inserting bolts into the holes. This allows for daily use... When in use, the protective shell 809 is rotatably connected to the annular groove 807 on the inner side of the fixed sleeve 805 via the annular part 808. It can rotate and open as needed for key insertion and removal. The two brush groups 810 symmetrically distributed on the inner side of the protective shell 809 can clean the dirt and dust on the key surface before the key is inserted into the keyhole 4, preventing dirt from being brought into the keyhole 4. At the same time, when the protective shell 809 is closed, it can block the keyhole 4, preventing external dust, oil and other impurities from falling directly into the keyhole 4, reducing the possibility of the lock cylinder 3 pins getting stuck or blocked, and greatly extending the service life of the lock cylinder 3.

[0017] Furthermore, the brush assembly 810 has two of the same size and is symmetrically distributed along the horizontal central axis of the annular part 808. With the arrangement of the brush assembly 810, the bristles of the brush assembly 810 will closely adhere to the key surface during use. As the key is inserted, the bristles will wipe and clean the dust, hair, oil and other stains on the front, back and sides of the key from all directions, preventing stains from entering the key hole 4 with the key and reducing the risk of the lock cylinder 3 pins getting stuck from the source.

[0018] Furthermore, the first mounting hole 804 has two holes of the same size, symmetrically distributed along the vertical central axis of the fixing piece 803. The second mounting hole 806 has two holes of the same size, symmetrically distributed along the vertical central axis of the fixing sleeve 805. The first mounting hole 804 and the second mounting hole 806 are the same size. With the first mounting hole 804 and the second mounting hole 806, the two symmetrically distributed mounting holes form a "two-point fixing" structure during use. Compared with single-point fixing, it can more evenly distribute the external force on the lock sleeve during use, avoid the fixing part from loosening or deformation due to uneven force, further enhance the overall connection stability between the lock sleeve and the doors, windows and furniture, and reduce later structural failures.

[0019] Furthermore, two limiting grooves 7 of the same size are provided and are symmetrically distributed along the vertical central axis of the all-steel outer shell 1. Two sliding blocks 802 of the same size are provided and are symmetrically distributed along the vertical central axis of the connecting sleeve 801. The inner wall size of the limiting groove 7 is adapted to the outer wall size of the sliding block 802. Through the setting of the limiting groove 7 and the sliding block 802, during use, the "T"-shaped design of the sliding block 802 and the matching structure of the limiting groove 7 can effectively limit the displacement of the connecting sleeve 801, ensuring that the connection between the connecting sleeve 801 and the all-steel outer shell 1 is always stable and reducing failures caused by structural loosening.

[0020] Furthermore, the inner wall dimensions of the connecting sleeve 801 are adapted to the outer wall dimensions of the all-steel outer shell 1, and the cross-section of the sliding block 802 is designed in a "T" shape. Through the setting of the connecting sleeve 801, the precise adaptation between the inner wall and the outer wall of the all-steel outer shell 1 during use provides a stable installation benchmark for the connecting sleeve 801. With the guidance of the sliding block 802 and the limiting groove 7, the connecting sleeve 801 and the all-steel outer shell 1 can be quickly and accurately aligned without repeated adjustments, greatly improving assembly efficiency.

[0021] Furthermore, the inner dimensions of the fixing sleeve 805 are adapted to the outer wall dimensions of the fixing plate 803. The horizontal and vertical central axes of the protective shell 809, the annular part 808, the fixing sleeve 805, and the fixing plate 803 coincide. Through the setting of the fixing sleeve 805 and the fixing plate 803, the fixing sleeve 805 and the fixing plate 803 form a tightly fitting connection structure during use. Then, with double fixing by bolts, the external force on the locking sleeve during use can be effectively dispersed, preventing the connection from loosening. At the same time, it provides a stable mounting carrier for the protective shell 809, ensuring the long-term effectiveness of the protective structure.

[0022] Furthermore, the inner wall dimensions of the annular groove 807 are adapted to the outer wall dimensions of the annular component 808. Two protective shells 809 of the same size are provided and are symmetrically distributed along the transverse central axis of the annular component 808. Through the provision of the annular groove 807 and the annular component 808, the annular component 808 can rotate inside the annular groove 807 during use. At the same time, the annular groove 807 can restrict the annular component 808 to ensure that the annular component 808 is not prone to displacement.

[0023] Working principle: First, align the connecting sleeve 801 with the outer side of the all-steel outer shell 1, so that the two "T"-shaped sliding blocks 802 on the inner side of the connecting sleeve 801 are precisely aligned with the two symmetrically distributed limiting grooves 7 on the all-steel outer shell 1. Utilizing the size compatibility between the sliding blocks 802 and the limiting grooves 7, the connecting sleeve 801 is smoothly inserted into the all-steel outer shell 1 along the limiting grooves 7 to achieve initial positioning. Next, the fixing sleeve 805 is fitted onto the outer side of the fixing piece 803. Because the inner dimensions of the fixing sleeve 805 are compatible with the outer wall dimensions of the fixing piece 803, and the two first mounting holes 804 on the fixing piece 803 and the two second mounting holes 806 on the fixing sleeve 805 are the same size and symmetrically distributed along the vertical central axis, the holes can be quickly aligned and fixed by inserting bolts into the holes. At the same time, the fixing bolt holes 5 on the all-steel outer shell 1 can further fix the entire locking sleeve to the door and window. The installation position of the furniture can be adjusted without repeated alignment, achieving efficient installation. In daily use, the protective shell 809 is rotatably connected to the annular groove 807 on the inner side of the fixed sleeve 805 through the annular part 808, and can be rotated to open and close as needed for key insertion and removal. The two brush groups 810 symmetrically distributed on the inner side of the protective shell 809 can clean the dirt and dust on the key surface before the key is inserted into the key hole 4, preventing dirt from being brought into the key hole 4. At the same time, when the protective shell 809 is closed, it can cover the key hole 4 to prevent external dust, oil and other impurities from falling directly into the key hole 4, reducing the possibility of the lock cylinder 3 pins getting stuck or blocked. The steel paddle 2 can work with the lock cylinder 3 to realize the lock opening and closing function, and the pin groove 6 is used to accommodate the lock pin assembly to ensure the normal locking performance of the lock. This completes the use process of a lock sleeve structure that is easy to install and position.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
