Abstract
Description
Technical Field
[0001] The utility model relates to a lock guard. Background Art
[0002] Locks are used to provide security, but the exposed part of the lock is easily hit by external forces, causing the lock core to be exposed and the lock to lose its protective function. The structure of some doors is not suitable for hiding the lock, so an external protective structure is required to prevent the lock from being damaged by external forces. Utility Model Content
[0003] In order to overcome the above-mentioned deficiencies, the present invention provides a lock guard that can protect the lock.
[0004] To achieve this purpose, the structure adopted by the utility model is: a lock guard, including a body, the body is a conical structure, the end with a larger diameter of the body is open, the end with a smaller diameter is provided with a platform, the platform is punched with a lock hole and a cover plate connecting hole, and a plurality of threaded holes are provided in the open end of the body.
[0005] The main body is integrally formed by metal powder injection molding.
[0006] A reinforcement plate is provided on the platform, and a lock hole and a cover plate connecting hole are provided on the reinforcement plate.
[0007] The platform is an oblong plane structure.
[0008] A fan-shaped limiting groove is arranged around the cover plate connecting hole.
[0009] An air hole is provided beside the cover plate connecting hole.
[0010] The beneficial effects are: the structural design of the utility model is reasonable and ingenious, the main body is covered on the outside of the lock, and the back is fixed by connecting the threaded hole with a screw, which wraps the lock to prevent the lock from being damaged by external force, and the conical structure has strong impact resistance and prevents deformation due to impact. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The present invention will be described by way of examples with reference to the accompanying drawings, in which:
[0012] Figure 1 It is a three-dimensional structural diagram of the utility model;
[0013] Figure 2 It is a front structural diagram of the utility model;
[0014] Figure 3 It is a rear view structural diagram of the present utility model. DETAILED DESCRIPTION
[0015] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0016] In the description of the utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0018] like Figure 1-Figure 3 The lock guard shown in the figure includes a body 1, which is a conical structure with an open end at the larger diameter and a platform 2 at the smaller diameter end. The open end and platform 2 have a smooth transition. The platform 2 is punched with a lock hole 4 and a cover plate connection hole 5. The open end of the body 1 is provided with multiple threaded holes 8. The body 1 covers the outside of the lock and is fixed to the back using screws connected to the threaded holes, enveloping the lock to protect it from external forces. The conical structure provides strong impact resistance and prevents deformation due to impact.
[0019] The main body 1 is formed as a whole from metal powder through an injection process. The overall structure has high strength, a smooth surface, and the size of the structure can be precisely controlled.
[0020] A reinforcement plate 3 is provided on the platform 2, and a lock hole 4 and a cover plate connection hole 5 are provided on the reinforcement plate 3. The reinforcement plate 3 reinforces the surface of the platform 2, enhances the anti-strike ability of the platform 2, and prevents the platform from deformation.
[0021] The platform 2 is an oblong planar structure, the open end of the main body 1 is oblong or circular, and the center line of the open end and the platform 2 can be on the same straight line or not. The width of the transition section between the open end of the main body 1 and the platform 2 at one end of the lock hole 4 is greater than the end of the cover plate connecting hole 5. On the premise of ensuring the overall impact resistance, the strength around the lock hole 4 is enhanced, and the inclined transition from the end of the cover plate connecting hole 5 to the lock hole 4 can facilitate gripping when rotating the cover plate connected to the cover plate connecting hole 5.
[0022] A fan-shaped limiting groove 6 is provided around the cover plate connecting hole 5 , and the limiting groove 6 is a movable space for the limiting block on the cover plate.
[0023] An air hole 7 is provided next to the cover plate connecting hole 5. The air hole 7 allows the water vapor in the body 1 to escape, thereby preventing the body 1 from covering the lock and causing water to accumulate inside and corrode the lock.
[0024] The portion around the cover plate connection hole 5 connected to the body 1 is recessed into the body 1 , and the cover plate connection hole 5 is tubularly arranged in the recessed portion so that the top of the cover plate connection hole 5 remains flush with or lower than the platform 2 .
[0025] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
