Description

Technical Field

[0001] This utility model relates to the field of locking technology, specifically a stable locking mechanism for a toolbox. Background Technology

[0002] A toolbox latch is a device used to secure and lock the lid of a toolbox, ensuring that tools will not be accidentally opened during transport or storage. To use a toolbox latch, first ensure the toolbox lid is fully closed. Then, align the latch's clips or pins with the corresponding latches or keyholes, and press or push the latch firmly until you hear a "click," indicating that it is securely locked. Some latches may have a key or combination lock function, requiring a key to be inserted or a combination to be entered to unlock. Unlocking is achieved by simply pressing the release button or turning the key. Before use, check that the latch is intact to avoid damage from forceful operation.

[0003] Some locks without combination locks or locking functions are locked and unlocked by pressing or pulling. However, if the toolbox is used on the construction site or is accidentally dropped by workers, the toolbox or its body may become deformed. This could also cause the hinge between the toolbox and the lid to deform, resulting in the lid not being able to completely seal the toolbox or creating a gap. Small gaps do not affect the use of the toolbox, but they will prevent the lock from locking the lid and the toolbox securely. Existing locks cannot fill the gaps caused by deformation of the toolbox or its body, resulting in the lid and the toolbox not being able to be locked securely.

[0004] In view of this, we propose a robust locking mechanism for toolboxes. Utility Model Content

[0005] The purpose of this utility model is to provide a stable lock for a toolbox. This stable lock solves the problem that deformation of the hinge between the toolbox body or lid and the toolbox body causes gaps between the lid and the toolbox body, making it impossible for the lock to lock securely.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sturdy lock for a toolbox includes a box body and a lid, with a handle on the side of the box body; it also includes a fixing component for stably fastening the box body and lid even when the box body or lid is deformed; the fixing component includes an upper fastener base, which is fixedly connected to the lid by bolts; a screw is provided on the inner side of the upper fastener base, which is rotatably connected to the upper fastener base; a knob is fixedly connected to one end of the screw on the outer side of the upper fastener base; a threaded sleeve is threaded through and connected to the inner side of the screw on the upper fastener base; a connecting rod is fixedly connected to the side of the threaded sleeve; an actuating plate is threaded through and rotatably connected to the end of the connecting rod away from the threaded sleeve; a telescopic rod is fixedly connected to the bottom surface of the actuating plate; and a fixing hook is inserted into and slidably connected to the bottom end of the telescopic rod.

[0008] Preferably, the telescopic rod is connected to a connecting sleeve through which it passes and is fixedly connected, and a rotating rod is fixedly connected to the side of the connecting sleeve.

[0009] Preferably, the upper fastener base has an inner cavity, the rotating rod is inserted into the inner wall of the cavity of the upper fastener base, and the rotating rod is rotatably connected to the upper fastener base.

[0010] Preferably, a sliding rod is fixedly connected to the side of the fixed hook, and a limiting groove is formed in the inner wall of the movable cavity, with the end of the sliding rod away from the fixed hook inserted into the inner side of the limiting groove.

[0011] Preferably, an anti-detachment plate is fixedly connected to one end of the telescopic rod located inside the fixed hook, and the anti-detachment plate is slidably connected to the fixed hook.

[0012] Preferably, a spring is sleeved on the outer side of a section of the telescopic rod located inside the fixed hook. One end of the spring is fixedly connected to the top surface of the anti-detachment plate, and the other end of the spring is fixedly connected to the inner side of the fixed hook.

[0013] Preferably, the surface of the box body is provided with a lower fastener base, the lower fastener base is fixedly connected to the surface of the box body by bolts, a press buckle is hinged to the inner side of the lower fastener base, a shaft is fixedly connected through the inner side of the press buckle, and a locking hook is rotatably connected through the shaft.

[0014] By employing the above technical solution, this utility model provides a stable locking mechanism for a toolbox. It possesses at least the following beneficial effects:

[0015] 1. This utility model uses a connecting rod to rotately connect the actuating plate, preventing the actuating plate and screw from interfering with each other and getting stuck. Simultaneously, the screw sleeve drives the actuating plate to slide within the upper fastener base via the connecting rod. Since the top surface of the telescopic rod is fixedly connected to the bottom surface of the actuating plate, and the side rotating rod of the connecting sleeve through which the telescopic rod passes is rotatably connected to the upper fastener base, the movement of the actuating plate causes the telescopic rod to rotate around the rotating rod as its axis. The telescopic rod then actuates the fixed hook. However, the sliding rod on the side of the fixed hook is limited by the limiting groove, allowing the fixed hook to rotate without detaching from the upper fastener base. The bottom end of the fixed hook will tilt upwards and move closer to the locking hook, thus compensating for slight gaps caused by the deformation of the hinge between the lid, body, or the lid and body. This allows for fine-tuning to ensure that the body and lid are always stably locked.

[0016] 2. When the toggle plate moves, it will actuate the telescopic rod to rotate around the pivot rod. The telescopic rod will then actuate the fixed hook. However, the sliding rod on the side of the fixed hook is limited by the limiting groove, so that the fixed hook can rotate without disengaging from the upper fastener base. However, the bottom of the fixed hook will be raised and will be relatively closer to the direction of the locking hook. It can be adapted to different box lids and boxes and can be locked. It is applicable to different box lids and boxes. Attached Figure Description

[0024] 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.

[0025] A toolbox with a secure latch, such as Figure 1 - Figure 5As shown, the device includes a box body 1 and a box cover 3. A handle 4 is provided on the side of the box body 1. It also includes a fixing component 2, which can stably fasten the box body 1 and the box cover 3 when either the box body 1 or the box cover 3 is deformed. The fixing component 2 includes an upper fastener base 25, which is fixedly connected to the box cover 3 by bolts. A screw 26 is provided on the inner side of the upper fastener base 25, and the screw 26 is rotatably connected to the upper fastener base 25. A knob 27 is fixedly connected to one end of the screw 26 located outside the upper fastener base 25. A threaded sleeve 28 is threaded through and connected to one end of the screw 26 located inside the upper fastener base 25. A connecting rod 29 is fixedly connected to the side of the threaded sleeve 28. A toggle plate 210 is rotatably connected to one end of the connecting rod 29 away from the threaded sleeve 28. The knob 27 is rotated... Since the screw 26 is rotatably connected to the upper fastener base 25, the screw 26 will rotate when the knob 27 is rotated. The screw sleeve 28, which is threaded through the screw 26, is connected to the actuating plate 210 through the connecting rod 29. The actuating plate 210 is slidably connected to the upper fastener base 25, so that the actuating plate 210 will limit the screw sleeve 28 relative to the connecting rod 29. This further causes the screw sleeve 28 to move on the screw 26 when it rotates. The rotatable connection between the connecting rod 29 and the actuating plate 210 prevents the actuating plate 210 and the screw 26 from interfering with each other and getting stuck. The bottom surface of the actuating plate 210 is fixedly connected to a telescopic rod 211, and the bottom end of the telescopic rod 211 is inserted into and slidably connected to a fixed hook 212. The telescopic rod 211 passes through and is fixedly connected to the connecting sleeve 216. A rotating rod 217 is fixedly connected to the side of the connecting sleeve 216. The screw sleeve 28 drives the actuating plate 210 to slide within the upper fastener base 25 via the connecting rod 29. Since the top surface of the telescopic rod 211 is fixedly connected to the bottom surface of the actuating plate 210, and the rotating rod 217 on the side of the connecting sleeve 216 through which the telescopic rod 211 passes is rotatably connected to the upper fastener base 25, the movement of the actuating plate 210 will cause the telescopic rod 211 to rotate around the rotating rod 217 as the axis. The inner side of the upper fastener base 25 has a movable cavity 214. The rotating rod 217 is inserted into the inner wall of the cavity of the upper fastener base 25, and the rotating rod 217 is rotatably connected to the upper fastener base 25. A sliding rod 213 is fixedly connected to the side of the fixed hook 212. A limiting groove 215 is opened in the inner wall of the movable cavity 214. The end of the sliding rod 213 away from the fixed hook 212 is inserted into the inner side of the limiting groove 215. An anti-detachment plate 218 is fixedly connected to the end of the telescopic rod 211 located inside the fixed hook 212. The anti-detachment plate 218 is slidably connected to the fixed hook 212. The telescopic rod 211 will move the fixed hook 212, but the sliding rod 213 on the side of the fixed hook 212 is limited in the limiting groove 215, so that the fixed hook 212 can rotate and will not detach from the upper fastener base 25. However, the bottom end of the fixed hook 212 will be raised and will be relatively closer to the direction of the locking hook 24, thereby compensating for the slight gap caused by the deformation of the hinge between the lid 3 or the body 1 or the lid 3 and the body 1.A spring 219 is sleeved on the outer side of one end of the telescopic rod 211 located inside the fixed hook 212. One end of the spring 219 is fixedly connected to the top surface of the anti-detachment plate 218, and the other end of the spring 219 is fixedly connected to the inner side of the fixed hook 212. A lower fastener base 21 is provided on the surface of the box body 1. The lower fastener base 21 is fixedly connected to the surface of the box body 1 by bolts. A press buckle 22 is hinged to the inner side of the lower fastener base 21. A shaft 23 is passed through and fixedly connected to the inner side of the press buckle 22. A locking hook 24 is passed through and rotatably connected to the shaft 23. First, the press buckle 22 is pushed upward, and the press buckle 22 will drive the locking hook 24 to rise first through the shaft 23. The locking hook 24 is manually pushed and aligned with the fixed hook 212. Then, the press buckle 22 is pushed downward, so that the press buckle 22 pulls the locking hook 24, so that the locking hook 24 tightens the fixed hook 212 to lock the box cover 3 and the box body 1.

[0026] In use, the toolbox locking mechanism of this utility model first connects the lower fastener base 21 and the upper fastener base 25 to the toolbox body 1 and the toolbox cover 3 respectively using bolts. To lock the toolbox body 1 and the toolbox cover 3, first push the push-button buckle 22 upwards. The push-button buckle 22 will then raise the locking hook 24 via the shaft 23. Manually push the locking hook 24 and align it with the fixing hook 212. Then, push the push-button buckle 22 downwards, causing it to pull the locking hook 24, thus tightening the fixing hook 212 and locking the toolbox cover 3. When the housing 1 is locked, if the housing 1, the lid 3, or the hinge between the lid 3 and the housing 1 deforms, causing a gap between the lid 3 and the housing 1 and preventing it from being locked, then the knob 27 can be turned. Since the screw 26 is rotatably connected to the upper fastener base 25, turning the knob 27 will drive the screw 26 to rotate. However, the threaded sleeve 28, through which the screw 26 passes, is connected to the actuating plate 210 via the connecting rod 29. The actuating plate 210 is slidably connected to the upper fastener base 25, so that the actuating plate 210 will relatively move the threaded sleeve 28 via the connecting rod 29. The limiting mechanism further ensures that when the screw 26 rotates, it will cause the screw sleeve 28 to move on the screw 26. The connecting rod 29 is rotatably connected to the actuating plate 210, preventing the actuating plate 210 from interfering with the screw 26 and becoming jammed. Simultaneously, the screw sleeve 28, through the connecting rod 29, will cause the actuating plate 210 to slide within the upper fastener base 25. Since the top surface of the telescopic rod 211 is fixedly connected to the bottom surface of the actuating plate 210, and the side rotating rod 217 of the connecting sleeve 216 through which the telescopic rod 211 passes is rotatably connected to the upper fastener base 25, the movement of the actuating plate 210... The telescopic rod 211 will rotate around the pivot rod 217, and the telescopic rod 211 will move the fixed hook 212. However, the sliding rod 213 on the side of the fixed hook 212 is limited by the limiting groove 215, so that the fixed hook 212 can rotate without disengaging from the upper fastener base 25. However, the bottom end of the fixed hook 212 will be raised and will be relatively closer to the locking hook 24, thereby compensating for the slight gap caused by the deformation of the hinge between the lid 3 or the body 1 or the lid 3 and the body 1, thus achieving fine adjustment to ensure that the body 1 and the lid 3 can always be stably locked.
