Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, specifically to a safety locking component for nail guns. Background Technology

[0002] Nail guns used in industries such as decoration and carpentry generally have a safety mechanism to prevent accidental triggering and nail firing. Common safety mechanisms utilize a safety push rod at the gun head to move a safety pad, which works in conjunction with the trigger. The safety pad resets after each use, requiring the safety push rod to be pressed down before pulling the trigger for frequent nail firing, which is inconvenient. Removing the safety mechanism poses safety risks. Chinese patent CN200820165058.1 discloses a nail gun head safety locking mechanism. The inner end of the safety push rod 1-1 is connected to one end of the safety pad 1-2, and the other end of the safety pad 1-2 engages with a corresponding part of the trigger 1-3. A locking element 1-5 is provided on the nail gun housing 1-4. This locking element 1-5 and the safety pad 1-2 are engaged through a through groove 1-6, forming a safety pad positioning and fixing device. Although this solution can release the safety of the nail gun, the safety pad 1-2 is located on the housing 1-4, and the safety push rod 1-1 and the safety pad 1-2 are connected by a long bend. This means that the locking part 1-5 cannot be accurately engaged in the narrow part of the through groove 1-6 every time, which can easily lead to errors. Utility Model Content

[0003] To address the technical problem that locking components 1-5 cannot always accurately engage with the narrow section of through slots 1-6, which easily leads to errors, this utility model proposes a safety locking component for nail guns. The limiting component is set on the nozzle and directly cooperates with the locking protrusion set on the safety head, resulting in high accuracy.

[0004] The technical solution adopted by this utility model is as follows: A safety locking assembly for a nail gun includes a nozzle and a safety head. One end of the safety head is provided with a support plate that slides and connects to the bottom of the nozzle, and the other end of the safety head is provided with a locking protrusion. The nozzle is rotatably equipped with a limiting assembly that movably engages with the locking protrusion. When the limiting assembly engages with the locking protrusion, the free end of the support plate is flush with the free end of the nozzle. When the user does not need to use the safety head, rotating the limiting assembly engages with the locking protrusion on the safety head, preventing the safety head from sliding and ensuring that the free end of the support plate remains flush with the free end of the nozzle. The limiting assembly is located on the nozzle and directly engages with the locking protrusion on the safety head, resulting in high precision.

[0005] Optionally, the limiting assembly includes a connecting rod and a limiting plate. The connecting rod is connected to the nozzle, one end of the limiting plate is rotatably connected to the connecting rod, and the other end of the limiting plate is provided with a groove that cooperates with the locking protrusion.

[0006] Optionally, the limiting plate has a push plate at an angle on the side opposite to the slot, and the push plate bends away from the nozzle. When it is necessary to release the locking state of the safety head, push the push plate upward to rotate the limiting plate in the opposite direction, thereby separating the slot from the protrusion and allowing the safety head to move freely. The push plate increases the ease of operation for the user.

[0007] Optionally, the limiting plate is provided with an angled baffle, which bends toward the nozzle. The baffle is located between the limiting plate and the nozzle to prevent the limiting plate from sliding excessively toward the nozzle, which would cause the slot to fail to engage with the protrusion, thus further improving the accuracy of the engagement between the limiting plate and the protrusion.

[0008] Optionally, the safety head includes a first side plate and a second side plate, one end of the support plate is connected to the first side plate, the other end of the support plate is connected to the second side plate, one side of the nozzle is slidably connected to the first side plate, and the other side of the nozzle is slidably connected to the second side plate, and the first side plate is provided with the locking protrusion.

[0009] Optionally, the nozzle has a first groove on one side and a second groove on the other side. The first side plate has a first hook that is slidably connected to the first groove, and the second side plate has a second hook that is slidably connected to the second groove.

[0010] Optionally, the first side plate and the second side plate are each provided with raised strips. The raised strips facilitate the user's movement of the fuse head.

[0011] Optionally, both the safety head and the nozzle are integrally molded structures.

[0012] The beneficial effects of this invention are as follows: When the user does not need to use the safety head, rotating the limiting component engages with the locking protrusion on the safety head, preventing the safety head from sliding and ensuring that the free end of the support plate remains flush with the free end of the nozzle. Because the limiting component is located on the nozzle, the accuracy of the engagement with the locking protrusion during the pushing of the safety head is greatly improved. The baffle is located between the limiting plate and the nozzle, preventing the limiting plate from sliding excessively towards the nozzle, which could cause the locking groove to fail to engage with the locking protrusion, further improving the accuracy of the engagement between the limiting plate and the locking protrusion.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] like Figure 2-4 As shown, this embodiment discloses a safety locking assembly for a nail gun, including a nozzle 1 and a safety head 2. One end of the safety head 2 has a support plate 21 that slides through the bottom of the nozzle 1, and the other end has a locking protrusion 22. The nozzle 1 is rotatably equipped with a limiting component 3 that engages with the locking protrusion 22. When the limiting component 3 engages with the locking protrusion 22, the free end of the support plate 21 is flush with the free end of the nozzle 1. When the user does not need to use the safety head 2, rotating the limiting component 3 engages with the locking protrusion 22 on the safety head 2, preventing the safety head 2 from sliding and ensuring that the free end of the support plate 21 remains flush with the free end of the nozzle 1. The limiting component 3, located on the nozzle 1, directly engages with the locking protrusion 22 on the safety head 2, resulting in high precision.

[0020] like Figure 3 As shown, the limiting component 3 includes a connecting rod 31 and a limiting plate 32. The connecting rod 31 is connected to the nozzle 1. One end of the limiting plate 32 is rotatably connected to the connecting rod 31, and the other end of the limiting plate 32 is provided with a slot 321 that cooperates with the locking protrusion 22.

[0021] In this embodiment, as Figure 2 As shown, the limiting plate 32 has a push plate 322 at an angle on the side opposite to the slot 321, and the push plate 322 is bent in the direction away from the nozzle 1. When it is necessary to release the locking state of the safety head 2, push the push plate 322 upward, causing the limiting plate 32 to rotate in the opposite direction, thereby separating the slot 321 from the locking protrusion 22, allowing the safety head 2 to move freely. The push plate 322 increases the ease of operation for the user.

[0022] like Figure 2As shown, the limiting plate 32 is provided with a baffle 323 at an angle, and the baffle 323 is bent toward the nozzle 1. The baffle 323 is located between the limiting plate 32 and the nozzle 1, which prevents the limiting plate 32 from sliding excessively toward the nozzle 1, thus preventing the slot 321 from failing to engage with the protrusion 22, and further improving the accuracy of the engagement between the limiting plate 32 and the protrusion 22.

[0023] like Figure 4 As shown, the safety head 2 includes a first side plate 23 and a second side plate 24. One end of the support plate 21 is connected to the first side plate 23, and the other end of the support plate 21 is connected to the second side plate 24. One side of the nozzle 1 is slidably connected to the first side plate 23, and the other side of the nozzle 1 is slidably connected to the second side plate 24. The first side plate 23 is provided with the locking protrusion 22. One side of the nozzle 1 is provided with a first strip groove 11, and the other side of the nozzle 1 is provided with a second strip groove 12. The first side plate 23 is provided with a first hook 25 slidably connected to the first strip groove 11, and the second side plate 24 is provided with a second hook 26 slidably connected to the second strip groove 12. Both the safety head 2 and the nozzle 1 are integrally formed structures.

[0024] like Figure 2 As shown, the first side plate 23 and the second side plate 24 are respectively provided with protrusions 27. The protrusions 27 facilitate the user's movement of the fuse head 2.
