Description

Technical Field

[0001] This utility model belongs to the field of nail gun equipment, and specifically relates to a nail gun protective device and a structure to prevent accidental injury. Background Technology

[0002] A nail gun is a device used to drive nails into various materials. Currently, nail guns frequently suffer from the problem of accidental nail scattering during use. This is due to the powerful impact of the nail gun firing, which causes nails to bounce in all directions if they are not precisely driven into the target object. The conventional solution is for users to wear protective gear such as safety glasses, but this only protects the eyes and other localized areas, leaving other parts of the body exposed to danger. Furthermore, protective gear may wear out or fog up over time, affecting vision and reducing its protective effectiveness. Secondly, nail guns are prone to accidental triggering without protection or anti-accidental injury structures. This is because traditional nail gun triggers are relatively simple, and collisions or accidental trigger presses during daily operation can easily lead to firing. A common solution is for users to operate with greater caution, but real-world working environments are complex and varied, making it difficult to maintain constant vigilance. Moreover, this relies on human attention and does not fundamentally solve the problem. Therefore, a new structure is needed to address these technical issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a nail gun protection device and an anti-accidental injury structure to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a nail gun protective device and an anti-accidental injury structure, comprising: a protective component one and a protective component two, the protective component one and the protective component two being installed on the outer surface of the nail gun assembly for preventing accidental injury to the user, the nail gun assembly including a nail gun head for nail ejection, a base and a handle being installed on the rear surface of the nail gun head, the protective component one including a locking member for locking the torsion spring, the protective component two including a protective cylinder for protecting against nail ejection, and an ejector being installed on the upper surface of the handle through a mounting groove.

[0005] In a preferred embodiment, a handle is integrally formed on the upper surface of the base. The handle has an L-shaped structure. A nailing port is installed on the upper surface of the base. A nail gun head is installed on the front surface of the base and the handle. The nail gun head communicates with the nailing port inside the base. A nail outlet is provided on the lower surface of the nail gun head.

[0006] In a preferred embodiment, a trigger is hinged at the connection between the grip and the upper surface of the nail gun head. The locking element includes a pressure plate, a roller, a hinge, and a locking plate. The pressure plate is hinged inside the grip, and a roller is mounted on the upper end of the pressure plate. The outer surface of the roller abuts against the lower surface of the trigger.

[0007] In a preferred embodiment, the pressure plate is hinged to the hinge, which is installed between the handle and the base. A torsion spring is installed between the hinge and the pressure plate. A locking plate is installed on the outer surface of the hinge and connected to the torsion spring. In use, the torsion spring is connected to the trigger, the handle, and the nail gun head. The connection between the trigger, the nail gun head, and the handle constitutes the firing mechanism of the nail gun. At this time, the torsion spring is connected to it. The locking plate can lock the torsion spring, which can effectively prevent the torsion spring from deforming or moving unexpectedly, thereby avoiding accidental firing of the nail gun.

[0008] In a preferred embodiment, a protective cylinder is installed at the nail outlet on the lower surface of the nail gun head. The lower surface of the protective cylinder has an outlet that is aligned with the nail outlet. An integral rim is formed on the lower surface of the protective cylinder, and a rubber pad is glued to the side of the rim away from the protective cylinder.

[0009] In a preferred embodiment, a pressure sensor is mounted on the lower surface of the cylinder edge via a rubber pad, the detection surface of the pressure sensor is not flush with the lower surface of the rubber pad, and the upper surface of the handle is recessed downward to form a mounting groove.

[0010] In a preferred embodiment, the ejector includes a miniature push rod. The miniature push rod is installed at the bottom of the mounting slot of the grip. The telescopic end of the miniature push rod abuts against the lower surface of the trigger. The single stroke of the miniature push rod is 50mm. During use, when the nail gun fires, the protective sleeve at the nail outlet can prevent nails from flying out, protecting the user and surrounding personnel from injury caused by accidental nail ejection. At the same time, when the nail gun is not in use, the ejector can fix the trigger in a non-triggered position, preventing accidental firing due to accidental triggering, thus enhancing the safety of the nail gun when not in use.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a protective component one, protective component one and protective component two are installed on the outer surface of the nail gun assembly to prevent accidental injury to the user. Protective component one includes a locking member for locking the torsion spring. When in use, the torsion spring is connected to the trigger, the handle and the nail gun head. The connection between the trigger, the nail gun head and the handle constitutes the firing structure of the nail gun. At this time, the torsion spring is connected to it. At this time, the torsion spring can be locked by the locking member, which can effectively prevent the torsion spring from deforming or moving under unexpected circumstances, thereby avoiding accidental firing of the nail gun and reducing the risk of the user being accidentally injured by the nail due to misoperation.

[0012] 2. By setting up a second protective component, which includes a protective sleeve for preventing nail ejection, and an ejector mounted on the upper surface of the handle via a mounting slot for fixing the trigger, the protective sleeve at the nail ejection point can prevent nails from flying out when the nail gun is fired, protecting the user and surrounding personnel from injury caused by accidental nail ejection. At the same time, when the nail gun is not in use, the ejector can fix the trigger in a non-triggered position to prevent accidental firing due to accidental triggering, thus enhancing the safety of the nail gun when not in use.

[0020] 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.

[0021] Please see Figures 1 to 3This utility model provides a technical solution: a nail gun protective device and an anti-accidental injury structure, including: a first protective component 200 and a second protective component. The first protective component 200 and the second protective component are installed on the outer surface of the nail gun assembly to prevent accidental injury to the user. The nail gun assembly includes a nail gun head 120 for nail ejection. A base 100 and a handle 110 are installed on the rear surface of the nail gun head 120. The first protective component 200 includes a locking member for locking the torsion spring 230. The second protective component includes a protective cylinder 300 for protecting against nail ejection. An ejector 340 is installed on the upper surface of the handle 110 through a mounting groove 111.

[0022] Please see Figures 1 to 3 As the first embodiment of this utility model: a handle 110 is integrally formed on the upper surface of the base 100. The handle 110 has an L-shaped structure. A nailing port is installed on the upper surface of the base 100. A nail gun head 120 is installed on the front surface of the base 100 and the handle 110. The nail gun head 120 communicates with the nailing port inside the base 100. A nail outlet is provided on the lower surface of the nail gun head 120.

[0023] A trigger 130 is hinged at the connection between the handle 110 and the upper surface of the nail gun head 120. The locking components include a pressure plate 210, a roller 220, a hinge 240, and a locking plate 250. The pressure plate 210 is hinged inside the handle 110. A roller 220 is installed at the upper end of the pressure plate 210. The outer surface of the roller 220 abuts against the lower surface of the trigger 130.

[0024] The pressure plate 210 is hinged to the hinge 240, which is installed between the handle 110 and the base 100. A torsion spring 230 is installed between the hinge 240 and the pressure plate 210. A locking plate 250 is installed on the outer surface of the hinge 240, and the locking plate 250 is connected to the torsion spring 230.

[0025] When using the device, the user first grips the handle 110, hooking their fingers around it, and then places their palm against the upper surface of the trigger 130. At this point, the user aligns the nail ejection point of the nail gun head 120 with the nailing location. After alignment, the user rotates the locking plate 250, disengaging it from the torsion spring 230. This allows the trigger 130 on the upper surface of the handle 110 to be pressed down via the torsion spring 230, triggering the firing mechanism between the nail gun head 120 and the handle 110. (The handle 110, base 100, and nail gun head 120 constitute the nail gun assembly. The specific firing mechanism and working principle of the nail gun assembly are existing technologies, and users can choose according to their actual needs; details are not provided here.) When the locking plate 250 rotates, the nail gun head 120 will fire according to the instructions provided. Figure 3It is known that the locking plate 250 is connected to the torsion spring 230 through the hinge of the pressure plate 210 and the hinge plate. The torsion spring 230 is also connected to the trigger 130, so that the trigger 130 can work normally, thereby protecting the user. Since the torsion spring 230 is connected to the connection of the trigger 130, the grip 110 and the nail gun head 120, the connection of the trigger 130, the nail gun head 120 and the grip 110 constitutes the firing structure of the nail gun. At this time, the torsion spring 230 is connected to it. At this time, the torsion spring 230 can be locked by the locking member, which can effectively prevent the torsion spring 230 from deforming or moving under unexpected circumstances, thereby avoiding accidental firing of the nail gun and reducing the risk of the user being injured by the nail due to misoperation.

[0026] Please see Figures 1 to 3 As a second embodiment of the present utility model: a protective cylinder 300 is installed at the nail outlet on the lower surface of the nail gun head 120. The lower surface of the protective cylinder 300 is provided with an outlet, and the outlet is aligned with the nail outlet. A cylinder edge 310 is integrally formed on the lower surface of the protective cylinder 300. A rubber pad 320 is glued to the side surface of the cylinder edge 310 away from the protective cylinder 300.

[0027] A pressure sensor 330 is installed on the lower surface of the cylinder edge 310 via a rubber pad 320. The detection surface of the pressure sensor 330 is not flush with the lower surface of the rubber pad 320. The upper surface of the handle 110 is recessed downward to form a mounting groove 111.

[0028] The ejector 340 includes a micro push rod, which is installed at the bottom of the mounting slot 111 of the grip 110. The telescopic end of the micro push rod abuts against the lower surface of the trigger 130. The stroke of the micro push rod is 50mm.

[0029] In use, after aligning the nail outlet with the nailed position according to the operation steps of the first embodiment, the protective cylinder 300 on the lower surface of the nail outlet is aligned with the nailed position. When the nail is ejected from the nail outlet, the protective cylinder 300 provides protection, preventing the nail from flying out without being driven into the nailed position and thus avoiding a threat to the user. Simultaneously, after the side surface of the protective cylinder 300 with the rubber pad 320 is aligned with the nailed position, the pressure sensor 330 on the lower surface of the protective cylinder 300 senses the pressure signal and transmits it to the ejector 340 (the pressure sensor 330 is prior art; any existing market device can be selected, as long as it meets the requirements; the specific working principle and structure are not detailed here). The ejector 340 is a miniature push rod (model Z-mod). When the ejector 340 receives a signal, the telescopic end of the micro push rod retracts, making the top of the telescopic end flush with the upper surface of the handle 110. This removes the pressure restraint on the lower surface of the trigger 130, allowing the trigger 130 to be used normally. (When the pressure sensor 330 loses signal transmission, the telescopic end of the micro push rod extends, thus restraining the trigger 130.) During use, when the nail gun fires, the protective sleeve 300 at the nail outlet prevents nails from flying out, protecting the user and surrounding personnel from injury caused by accidental nail ejection. At the same time, when the nail gun is not in use, the ejector 340 can fix the trigger 130 in a non-triggering position, preventing accidental firing due to accidental triggering of the trigger 130, thus enhancing the safety of the nail gun when not in use.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
