Description

Technical Field

[0001] This utility model relates to the field of cylindrical locks, specifically a high-strength, weather-resistant cylindrical lock. Background Technology

[0002] Cylindrical locks are widely used in the opening and closing mechanisms of various cabinets and equipment due to their simple structure and convenient installation. However, existing cylindrical locks often face problems such as insufficient structural strength and poor weather resistance in actual use.

[0003] In the prior art, Chinese patent with authorization announcement number CN218176928U discloses a sheet metal plastic-coated cylindrical lock, which is designed to solve the technical problem that the stainless steel material of the lock cylinder shaft or base in existing similar cylindrical lock products lacks a plastic-coated structure, resulting in higher production costs for all-metal structures or poor stability for all-plastic structures. The cylindrical lock has a base with a lock cylinder shaft extending from one end at the bottom, and the other end of the lock cylinder shaft protruding from the lock hole at the top of the base. The key feature is that the base includes a stainless steel base cover and a plastic injection-molded base. The top lock hole of the stainless steel base cover has an outwardly extending annular skirt. The stainless steel base cover fits into the top lock hole of the plastic injection-molded base, and the annular skirt of the stainless steel base cover fits into the edge of the lock hole of the plastic injection-molded base. The inner lock hole of the stainless steel base cover fits into the inner wall of the lock hole of the plastic injection-molded base. Simultaneously, the top opening of the stainless steel lock cylinder shaft cover and the plastic injection-molded lock cylinder shaft have a central hole at the bottom center. Although this invention is easy to assemble, its weather resistance is poor under different environments, and external factors can easily corrode the lock cylinder structure, affecting the use of the cylindrical lock. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a high-strength and weather-resistant cylindrical lock to solve the technical problem of low weather resistance of ordinary cylindrical locks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, weather-resistant cylindrical lock, comprising a lock cylinder, a housing, and a cabinet door. The lock cylinder is fitted inside the housing. One end of the housing is fixedly connected to a base. A limiting nut is threaded onto the outer wall of the housing. A support assembly for supporting the housing is threaded onto the outer wall of the housing. The support assembly includes a support sleeve and multiple support plates. The support plates are uniformly fixedly connected to the outer wall of the support sleeve. The support sleeve is threaded onto the outer wall of the housing. A groove for engaging the cabinet door is formed between the base and the limiting nut. A protective cover is threaded onto the side of the base away from the cabinet door. A sealing gasket is provided at the end of the protective cover that contacts the cabinet door. A locking block for preventing the lock cylinder from moving is threaded onto the inside of the housing. A sealing cover is provided at the end of the housing away from the locking block.

[0006] By adopting the above technical solution, the lock cylinder is sleeved inside the housing, and a groove is formed between the base at one end of the housing and the limiting nut on the outer wall, which can securely lock the cabinet door. The support plate can support the housing from multiple directions, enhancing the overall structural stability and strength of the housing. The internal locking block can effectively restrict the movement of the lock cylinder, preventing displacement of the lock cylinder during use and thus preventing functional failure. The protective cover on the side of the base away from the cabinet door and the sealing cover on the side of the housing away from the locking block together form a closed protection for the lock cylinder and other internal components, reducing the impact of external factors on the internal structure and improving weather resistance. The sealing gasket at the end of the protective cover can enhance the sealing of the contact area between the lock body and the cabinet door, preventing moisture, dust and other impurities from entering the interior of the lock body, reducing the risk of damage to internal components due to corrosion, and improving the weather resistance of the cylindrical lock in different environments.

[0007] Furthermore, one end of the lock cylinder is fixedly connected to a lock cylinder head for engaging with a key, and the other end of the lock cylinder is fixedly connected to a steel bolt by screws.

[0008] By adopting the above technical solution, the lock cylinder head at one end of the lock cylinder cooperates with the key to provide a reliable operating interface for opening and closing the lock, ensuring that the key can accurately drive the lock cylinder to move. The steel bolt at the other end of the lock cylinder is fixedly connected by screws. This connection method can ensure the connection strength between the steel bolt and the lock cylinder, prevent the steel bolt from loosening or falling off during the rotation of the lock cylinder, and ensure that the rotation of the lock cylinder can be synchronously transmitted to the steel bolt.

[0009] Furthermore, a first limiting post is fixedly connected to the side of the base near the cabinet door, and a first limiting groove for inserting the first limiting post is provided on the cabinet door.

[0010] By adopting the above technical solution, the first limiting post on the side of the base near the cabinet door is inserted into the first limiting groove on the cabinet door, which can effectively limit the relative position between the base and the cabinet door, preventing them from rotating or displacing relative to each other due to external forces such as vibration and collision during use, and enhancing the stability of the connection between the lock body and the cabinet door.

[0011] Furthermore, a second limiting post is fixedly connected to the end of the sealing cover facing the housing, and a second limiting groove for inserting the second limiting post is provided on the housing.

[0012] By adopting the above technical solution, the second limiting post at the end of the sealing cover facing the housing is inserted into the second limiting groove of the housing, which can effectively limit the relative rotation between the sealing cover and the housing, and ensure that the sealing cover will not be affected by the rotation of the lock cylinder and the steel bolt after installation.

[0013] Furthermore, the screw passes through the sealing cover and connects to the lock cylinder.

[0014] By adopting the above technical solution, the screw passes through the protective cover and connects to the lock cylinder, fixing the steel bolt and the lock cylinder so that the sealing cover is not affected when the lock cylinder and the steel bolt rotate.

[0015] Furthermore, the housing is made of high-strength alloy steel.

[0016] By adopting the above technical solution, the shell is made of high-strength alloy steel, which has high mechanical strength and impact resistance. It can effectively resist external impacts, compression and other external forces, reduce the risk of deformation or damage to the shell due to force, and ensure the shell's protective function for internal components such as the lock cylinder.

[0017] Furthermore, a sealing ring is provided between the sealing cover and the housing.

[0018] By adopting the above technical solution, the sealing ring can effectively enhance the sealing performance of the connection between the two, preventing external moisture, dust, impurities, etc. from entering the interior of the housing through the gap between the cover plate and the housing, avoiding malfunctions of internal components such as the lock cylinder due to corrosion, protecting the integrity of the internal structure, and ensuring the normal function of the lock.

[0019] In summary, the present invention has the following main advantages: This utility model uses the base and the limiting nut on the outer wall to form a groove, which can securely lock the cabinet door, prevent the cabinet door and the lock body from shaking relative to each other, and improve stability. The cooperation of the support sleeve and multiple support plates can support the shell from multiple directions, enhance the shell's load-bearing capacity and overall structural stability. This utility model uses the cooperation of a protective cover, a shell, and a sealing cover to jointly seal and protect the internal components, prevent moisture and dust from entering, reduce the risk of internal components being corroded, and improve the weather resistance of the cylindrical lock in different environments.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this example: a high-strength, weather-resistant cylindrical lock, such as... Figure 1-4 As shown, the device includes a lock cylinder 1, a housing 2, and a cabinet door 3. The lock cylinder 1 is the opening and closing component of the lock. The housing 2 protects the lock cylinder 1 and provides a mounting base. The lock cylinder 1 is fitted inside the housing 2, and the fitting structure enables the lock cylinder 1 and housing 2 to be assembled and connected, while also protecting the lock cylinder 1. One end of the housing 2 is fixedly connected to a base 4, which increases the load-bearing area at the end of the housing 2 and improves the stability of the connection between the housing 2 and the external structure. A limiting nut 5 is threaded onto the outer wall of the housing 2, allowing the limiting nut 5 to be adjusted axially along the housing 2. The housing 2 is designed to accommodate cabinet doors of varying thicknesses. A support assembly is threaded onto the outer wall of the housing 2, allowing for detachable connection between the support assembly and the housing 2. This facilitates installation and replacement, while also providing auxiliary support to the housing 2. The support assembly includes a support sleeve 7 and multiple support plates 8. The support plates 8 are evenly and fixedly connected to the outer wall of the support sleeve 7, providing a mounting base for the support plates 8. The multiple support plates 8 can distribute force from different directions. The support sleeve 7 is threaded onto the outer wall of the housing 2, allowing for adjustment of the support assembly within the housing. At position on body 2, a groove 9 is formed between the base 4 and the limiting nut 5 for engaging the cabinet door 3. The groove 9 securely clamps the cabinet door 3 between the base 4 and the limiting nut 5, achieving a tight connection between the lock body and the cabinet door 3. A protective cover 10 is threadedly connected to the side of the base 4 away from the cabinet door 3. The protective cover 10 is removable via a threaded connection, facilitating maintenance of the inner structure of the base 4. A sealing gasket 11 is provided at the end of the protective cover 10 that contacts the cabinet door 3. A sealing gasket 11 is provided, which can fill the gap between the protective cover 10 and the cabinet door 3, improve the sealing performance of this part, and prevent moisture and dust from entering. The housing 2 is internally threaded with a locking block 12 to prevent the lock cylinder 1 from moving. The locking block 12 is firmly fixed to the housing 2 through the threaded connection, which can effectively limit the axial movement of the lock cylinder 1 in the housing 2 and ensure the stability of the lock cylinder 1 position. A sealing cover 13 is provided at the end of the housing 2 away from the locking block 12. The sealing cover 13 can seal this end of the housing 2 to prevent external impurities from entering the interior of the housing 2 and further protect the structure of the lock cylinder 1. See Figure 1 , Figure 2 , Figure 3 , Figure 4 One end of the lock cylinder 1 is fixedly connected to a lock cylinder head 14 for cooperating with a key. The lock cylinder head 14 provides an operating interface for the key, ensuring that the key can accurately drive the lock cylinder 1 to move. The other end of the lock cylinder 1 is fixedly connected to a steel bolt 15. The steel bolt 15 is fixedly connected to the lock cylinder 1 by a screw 16. The screw 16 connection method can ensure that the steel bolt 15 is firmly connected to the lock cylinder 1, preventing the steel bolt 15 from loosening or falling off during operation, and ensuring that the power of the lock cylinder 1 can be effectively transmitted to the steel bolt 15. See Figure 1 , Figure 2 , Figure 3 , Figure 4 The base 4 is fixedly connected to a first limiting post 17 on the side near the cabinet door 3. The cabinet door 3 is provided with a first limiting groove 18 for inserting the first limiting post 17, which enhances the stability of the connection between the two and prevents the position shift and rotation of the shell 2 during use. See Figure 2 The end of the sealing cover 13 facing the housing 2 is fixedly connected to a second limiting post 19. The housing 2 is provided with a second limiting groove 20 for inserting the second limiting post 19, so as to ensure that the sealing cover 13 is installed in an accurate position and to avoid the sealing cover 13 from loosening and rotating, which would affect the sealing effect. See Figure 2 The screw 16 passes through the sealing cover 13 and connects to the lock cylinder 1. This structure can fix the steel bolt 15 and the lock cylinder 1 while fixing the sealing cover 13, reducing the number of components that independently fix the sealing cover 13 and simplifying the lock body structure. See Figure 1 , Figure 2 The housing 2 is made of high-strength alloy steel, which has high mechanical strength and corrosion resistance, and can improve the impact resistance and weather resistance of the housing 2, and extend the service life of the lock. See Figure 1 , Figure 2 , Figure 3 , Figure 4 A sealing ring 21 is provided between the sealing cover 13 and the housing 2. The sealing ring 21 can enhance the sealing performance between the sealing cover 13 and the housing 2, further preventing moisture, dust and other impurities from entering the interior of the housing 2 and protecting the internal components from corrosion. The implementation principle of this embodiment is as follows: First, the lock cylinder 1 is fitted into the housing 2 and fixed by the threaded connection of the locking block 12 inside the housing 2 to prevent the lock cylinder 1 from moving. One end of the housing 2 is fixed to the base 4, and the outer wall is threadedly connected to the limiting nut 5. The groove 9 formed by the two is used to lock the cabinet door 3. At the same time, the support assembly on the outer wall of the housing 2 enhances the overall stability through the support sleeve 7 and the support plate 8. The lock cylinder head 14 at one end of the lock cylinder 1 is used to cooperate with the key, and the other end is connected to the steel bolt 15 through the screw 16 to realize the opening and closing action of the lock. The first limiting post 17 of the base 4 cooperates with the first limiting groove 18 of the cabinet door 3 to improve the connection stability; the protective cover 10 is threaded on the side of the base 4 away from the cabinet door 3, and the sealing gasket 11 at its end enhances the sealing performance; a sealing cover 13 is provided at the end of the housing 2 away from the locking block 12, and the second limiting post 19 of the sealing cover 13 cooperates with the second limiting groove 20 of the housing 2 to prevent rotation, and the sealing ring 21 between the sealing cover 13 and the housing 2 further strengthens the sealing; the screw 16 passes through the sealing cover 13 and connects to the lock cylinder 1, which also serves to fix the steel bolt 15 and the sealing cover 13; the housing 2 is made of high-strength alloy steel, and the overall structure achieves high strength and weather resistance through the coordinated cooperation of various components, ensuring that the lock is stable and reliable in use.
