Nail gun with easy assembly

Abstract

This invention provides a nail gun that is easy to assemble, including a housing and a firing pin drive mechanism, a motor, and multiple internal components housed within the housing. The housing includes a receiving housing and a limiting housing that match each other and can be assembled into a single housing. Since the receiving parts for accommodating the internal components of the nail gun are all located on the receiving housing, and the limiting housing only has limiting parts corresponding to the receiving parts, and the internal components are all housed on one of the housings, during assembly or disassembly and maintenance, it is only necessary to align and combine the outer contours of the limiting housing and the receiving housing, without having to align and embed the other half of the internal components into the groove of the other housing as in traditional installation structures. Therefore, it is easier to assemble the left and right housings together, thereby improving the user experience and increasing the efficiency of assembly and maintenance.

Description

Technical Field

[0001] This invention belongs to the field of nail gun technology, and specifically relates to a nail gun that is easy to assemble. Background Technology

[0002] A nail gun is a fastening tool, primarily used in construction, that propels nails by striking them with a firing pin. Currently, the most commonly used nail gun is an electric nail gun powered by a lithium battery. This type of nail gun has an outer casing composed of two sub-casings, each with mounting structures on its inner surface to house and secure internal components such as the motor and nail drive mechanism. Most nail guns on the market have symmetrical mounting structures on the inner surfaces of the two sub-casings; that is, for each internal component, the left sub-casing has one half of the mounting structure, and the right sub-casing has the other half, requiring the two halves to be aligned during installation. However, due to the elasticity of the casing, deformation occurs when the casing is closed, and the mounting structures on the inner surfaces are not visible when closed, making it difficult to perfectly align the two halves. The large number and varied shapes of the internal components further complicate the process, making the alignment of multiple sets of halves even more challenging. This results in inconvenient and time-consuming disassembly and assembly of the casing, impacting the efficiency of nail gun assembly and maintenance.

[0003] Therefore, in order to solve the above problems, there is an urgent need for a nail gun housing structure that is easier to install. Summary of the Invention

[0034] <Example>

[0035] Figure 1 This is a perspective view of the nail gun in this embodiment.

[0036] Figure 2 This is a perspective view of the nail gun structure in this embodiment. The right housing is omitted in the figure to show the internal structure.

[0037] Figure 3 This is an orthographic projection of the nail gun structure in this embodiment. To show the installation structure of the components inside the left housing, the right housing and the firing pin drive mechanism are omitted in the figure.

[0038] like Figure 1-3 As shown, the nail gun 10 includes a housing, a firing pin drive mechanism 40, a nozzle 50, a nail magazine 60, a switch assembly, a motor assembly 70, and a circuit board assembly 80. The nail gun 10 also includes conventional components such as a lithium battery (not shown in the figure).

[0039] The housing includes a left housing 20 and a right housing 30 that match each other and can be assembled to form an integral housing for accommodating the aforementioned firing pin drive mechanism 40, motor assembly 70, circuit board assembly 80, and switch assembly. In this embodiment, the left housing 20 serves as a housing for accommodating the internal components, while the right housing 30 serves as a limiting housing for limiting the movement of the internal components. After the left housing 20 and right housing 30 are combined, a replacement opening is formed at their top. The nail gun also includes a baffle 12, which is detachably installed at the replacement opening. Removing the baffle 12 allows for easy replacement of the internal firing pin.

[0040] The firing pin drive mechanism 40 includes a regulating frame 41 and a guide rod 42, a spring assembly 43, and a piston 44 disposed within the regulating frame 41. Under the force of the spring assembly 43, the piston 44 drives the firing pin mounted thereon to move in a predetermined direction, thereby striking the nail and ejecting it. The regulating frame 41 is a square frame.

[0041] The motor assembly 70 includes a motor 71, a reduction and torque amplification unit 72, a one-way bearing 73, and a drive wheel 74.

[0042] The motor 71 drives the drive wheel 74 to rotate, and pushes the piston 44 to move through the columnar protrusions on the surface of the drive wheel 74, thereby compressing the spring assembly 43 to store energy. In this embodiment, the motor 71 is a brushless motor. The motor 71 is generally cylindrical in shape.

[0043] The speed reduction and torque amplification unit 72 is installed at the output end of the motor 71 to reduce the speed at the output end of the motor 71, thereby obtaining higher output torque, i.e., greater driving force. The speed reduction and torque amplification unit 72 is cylindrical at both ends and has an inwardly concave part in the middle, so that one of its cross-sections is roughly I-shaped.

[0044] A one-way bearing 73 is connected between the speed reduction and torque amplification unit 72 and the drive wheel 74, so that the drive wheel 74 can only rotate in one direction.

[0045] The circuit board assembly 80 includes a circuit board 81, a power button unit 82, and multiple wires (not shown in the figure). The power button unit 82 is connected to one side of the circuit board 81. When the operator presses the power button on this unit, the nail gun 10 is turned on. The micro switch and the motor 71 are both connected to the circuit board 81 via wires.

[0046] The switch assembly includes a nail gun switch 91, a protective switch 92, a safety switch 93, and an energy storage stop switch 94. The nail gun switch 91 and the protective switch 92 are located at the handle, the safety switch 93 is located near the nozzle, and the energy storage stop switch 94 is located next to the firing pin drive mechanism 30.

[0047] Figure 4 This is a diagram showing the installation structure of the internal components in the left shell handle section of this embodiment.

[0048] like Figure 4 As shown, the nail gun switch 91 includes a nail gun pressing member 911, a nail gun switching element 912, and a nail gun reset member 913.

[0049] Figure 5 This is a perspective view of the pressing component for the nail gun in this embodiment.

[0050] like Figure 5 As shown, the nail-shooting pressing member 911 includes a pressing body 9111, a connecting post 9112 integrally formed on the upper end of one side of the pressing body 9111, a spring connecting post 9113 in the middle of one side, a pushing post 9114 at the lower end of one side, and a limiting protrusion 9115 at the bottom of one side. The other side of the pressing body 9111 is concave and arc-shaped, making it easy for the operator to press with their fingers. The nail-shooting switching element 912 is a micro switch with a trigger spring. When the nail-shooting pressing member 911 is pressed, it actuates the spring, and the micro switch generates a corresponding signal. In addition, the micro switch has two through holes in the middle for installation. The nail-shooting reset member 913 is a spring.

[0051] The protective switch 92 includes a protective pressing element 921, a protective switching element 922, and a protective resetting element 923. The protective pressing element 921 is button-shaped, with one side for the operator to press and a circular groove on the other side for housing a spring. The protective switching element 922 is also a micro switch, and the protective resetting element 923 is also a spring.

[0052] Figure 6 This is a diagram showing the installation structure of the internal components in the upper main body of the left shell in this embodiment.

[0053] like Figure 6 As shown, the safety switch 93 includes a crank rod 931, a connecting rod 932, a bent rod 933, a safety switching element 934, and a safety reset element 935. The crank rod 931, connecting rod 932, and bent rod 933 abut against each other in sequence to trigger the safety switching element 934. The safety switching element 934 is also a microswitch, and the safety reset element 935 is also a spring.

[0054] The energy storage stop switch 94 includes a stop push member 941 and a stop switch element 942. One end of the stop push member 941 is coiled and the other end is generally straight, and it is used to rotate and trigger the stop switch element 942 when the piston 44 moves to its position. The stop switch element 942 is also a micro switch.

[0055] The installation positions of the above components will be explained in detail below in conjunction with the casing structure.

[0056] Figure 7 , Figure 8 These are, respectively, a perspective view and a frontal projection view of the left casing in this embodiment.

[0057] like Figure 7-8 As shown, the left housing 20 can be divided into the upper main body 21 of the left housing, the lower main body 22 of the left housing, the handle part 23 of the left housing, and the connecting part 24 of the left housing.

[0058] Figure 9 , Figure 10 These are, respectively, a perspective view and a frontal projection view of the right casing in this embodiment.

[0059] like Figure 9-10 As shown, the right housing 30 can be divided into the upper main body 31, the lower main body 32, the handle 33, and the connecting part 34, which are corresponding to the left housing 20.

[0060] The inner surfaces of the left upper main body 21 and the right upper main body 31 both have grid-like protrusions, which together form a receiving groove for accommodating the firing pin drive mechanism 30. The protrusions on the inner surface of the housing also serve as reinforcing ribs.

[0061] Figure 11 yes Figure 8 Enlarged view of the inner part of frame A.

[0062] like Figure 11 As shown, a circular pressing member mounting hole 234 is provided at the connection position between the left housing handle portion 23 and the left housing upper main body portion 21 of the left housing 20, and a circular mounting hole is also provided at the corresponding position of the right housing 30; the two ends of the connecting post portion 9112 at the upper end of the nail pressing member 911 are rotatably fitted into the pressing member mounting hole 234 of the left housing 20 and the corresponding mounting hole of the right housing 30, so that the nail pressing member 911 can rotate with its connecting post portion 9112 as the pivot.

[0063] The left housing handle portion 23 has a first switch notch 235 and a second switch notch 236 on the side near the left housing connecting portion 24, and the right housing 30 also has a corresponding notch. The nail-shooting pressing member 911 is partially housed in the left housing handle portion 23, with one arc-shaped side protruding from the first switch notch 235. The protective pressing member 921 is partially housed in the left housing handle portion 23, with one side protruding from the second switch notch 236. A handle member limiting groove 2351 is also formed on the inner surface of the left housing handle portion 23 at the lower end of the first switch notch 235 to limit the rotation range of the nail-shooting pressing member 911. Under the action of the reset member, the nail-shooting pressing member 911 is limited to rotate until the limiting protrusion 9115 at its bottom abuts against the handle member limiting groove 2351.

[0064] The inner surface of the left handle portion 23 of the left housing 20 has multiple protrusions, forming a nail gun switch receiving portion 231 and a safety switch receiving portion 232. The inner surface of the right handle portion 33 of the right housing 30 has corresponding nail gun switch limiting portions 331 and safety switch limiting portions 332.

[0065] The nail switch receiving part 231 includes a nail reset member receiving groove 2311 and a nail element fitting part 2312. The nail reset member receiving groove 2311 is a square groove with one side opening, used to receive the nail reset member 913 (spring). One end of the spring abuts against the side wall inside the nail reset member receiving groove 2311, and the other end is fitted onto the spring connecting post 9113 of the nail pressing member 911. The nail element fitting part 2312 is disposed between the outer walls of the nail reset member receiving groove 2311 and the protective reset member receiving groove 2321, used to fix the nail switch element 912 (micro switch). The nail element fitting part 2312 includes two nail element limiting protrusions 2312a, two nail element fixing protrusions 2312b, and a nail element limiting strip 2312c. In this embodiment, the nail element fixing protrusion 2312b consists of two cylindrical protrusions, the size and arrangement of which are adapted to the two through holes on the micro switch. The micro switch is fixed by passing through these two through holes. Among them, the two nail element limiting protrusions 2312a are square columnar protrusions used to limit one side of the micro switch in the width direction, and the other is a strip-shaped protrusion used to limit one side of the micro switch in the length direction. The other side of the micro switch in the length direction is limited by one outer wall of the nail reset member receiving groove 2311.

[0066] In addition, the opening side of the nail-shooting reset member receiving groove 2311 also has a protruding beveled portion 2311a. When the nail-shooting pressing member 911 is pressed down and rotated into position, it abuts against the beveled portion 2311a, thereby limiting the rotation range of the nail-shooting pressing member 911.

[0067] The nail switch limiting part 331 is a grid-shaped protrusion, and its structure corresponds to the nail reset member receiving groove 2311 and the nail element fitting part 2312. It is used to press the other side of the micro switch and spring together to limit the movement.

[0068] The protective switch receiving portion 232 includes a protective reset member receiving groove 2321 and a protective element fitting portion 2322. The protective reset member receiving groove 2321 is also a square groove with an opening on one side, used to receive the protective reset member 923 (spring). One end of the spring abuts against the side wall inside the groove of the protective reset member receiving groove 2321, and the other end abuts against the bottom of the circular groove on one side of the protective pressing member 921. The protective element fitting portion 2322 includes three protective element limiting protrusions 2322a and three protective element fixing protrusions 2322b. Its structure is similar to that of the nail gun element fitting portion 2312. The difference is that, relative to the nail gun switch receiving portion 231, the protective element fitting portion 2322 is inclined as a whole, so that the trigger spring of the micro switch installed there is tilted upward, so that the protective pressing member 921 can be closer to the nail gun pressing member 911, which is convenient for operation.

[0069] The protective switch limiting part 332 is also a grid-shaped protrusion. Its structure corresponds to the protective reset member receiving groove 2321 and the protective element fitting part 2322. It is used to press the other side of the micro switch and spring together to limit the movement.

[0070] Figure 12 yes Figure 8 Enlarged view of the inner part of frame B.

[0071] like Figure 12 As shown, the inner surface of the main body 21 on the left shell also has a safety switch receiving portion 211 and a stop switch receiving portion 212, both formed between the grid-like protrusions.

[0072] The safety switch receiving part 211 is located near the nozzle 50, and includes a connecting rod receiving groove 2111, a safety reset member receiving groove 2112, a bent rod receiving groove 2113, and a safety element fitting part 2114.

[0073] The connecting rod receiving groove 2111 is a square groove with an opening on one side in the length direction and one on the other side in the width direction. The opening on the side in the width direction is larger. There is an annular protrusion 2111a inside the groove. The lower surface of the annular protrusion 2111a is flat. The connecting rod 932 is fitted into the connecting rod receiving groove 2111. Its two ends extend from the two openings respectively, and its middle part is limited by the lower surface of the annular protrusion 2111a and the groove wall.

[0074] The safety resettlement groove 2112 is adjacent to the connecting rod groove 2111 and is also a square groove with an opening on one side in the width direction of the square groove.

[0075] The bent rod receiving groove 2113 is located below and adjacent to the safety reset member receiving groove 2112. The bent rod receiving groove 2113 has openings on both sides, one side of which communicates with the safety element fitting part 2114, and the other side communicates with the safety reset member receiving groove 2112. The longer end of the bent rod 933 is fitted into the bent rod receiving groove 2113, and the other end extends to the safety reset member receiving groove 2112 and abuts against one end of the connecting rod 932. One end of the safety reset member 935 (spring) abuts against one side wall of the safety reset member receiving groove 2112, and the other end abuts against one end of the bent rod 933.

[0076] The crank rod 931 is mounted on the nozzle 50 via a limiting plate and can move in a predetermined reciprocating direction. One end of the crank rod 931 abuts against the end of the connecting rod 932 extending outward.

[0077] The safety element fitting part 2114 includes multiple safety element limiting protrusions 2114a and two safety element fixing protrusions 2114b. The safety element limiting protrusions 2114a are columnar or irregularly shaped protrusions, used to limit the micro switch on both sides in the length direction and one side in the width direction, respectively. The two safety element fixing protrusions 2114b are cylindrical protrusions. The micro switch is installed between the safety element limiting protrusions 2114a, with the fixing protrusions 2114b passing through their two through holes to fix the micro switch. The trigger spring of the micro switch is located at the opening on one side of the bent rod receiving groove 2113. Furthermore, a clearance structure is formed between adjacent safety element limiting protrusions 2114a to allow space for the terminals of the micro switch to connect wires.

[0078] Therefore, when the operator presses the nozzle 50 against the nozzle, the crank 931 on the nozzle 50 is pressed and moves along the direction of spring energy storage, pushing the connecting rod 932 and the bent rod 933 to move. The end of the bent rod 933 presses the trigger spring of the micro switch, generating a corresponding electrical signal.

[0079] The stop switch receiving part 212 includes a stop element fitting part 2121 and a pusher receiving groove 2122. The structure of the stop element fitting part 2121 is similar to that of the safety element fitting part 2114, and will not be described in detail. A cylindrical protrusion is provided in the groove of the pusher receiving groove 2122. One curled end of the stop pusher 941 is mounted on the cylindrical protrusion and can rotate around the protrusion. The other end of the stop pusher 941 is located at a limiting opening 2123 of the grid-like protrusion, and its rotation range is limited by the limiting opening 2123.

[0080] When the spring assembly 43 has not completed its energy storage, under the action of gravity, the other end of the stop push member 941 abuts against the lower end of the limit opening 2123; and when the spring assembly 43 has completed its energy storage, the piston 44 reaches the stop push member 941, pushes it upward, and presses the trigger spring of the micro switch.

[0081] After installation, the other side of the aforementioned crank 931, connecting rod 932, bent rod 933, and micro switch is pressed and limited by one side of the regulating frame 41.

[0082] In addition, the grid-like protrusions on the inner surface of the main body 21 on the left shell have multiple wiring notches 219 for wiring the wires of the two microswitches.

[0083] The lower half of the left shell connecting part 24 and the lower half of the right shell connecting part 34 both have multiple annular protrusions on their inner surfaces. When combined, the lower half forms a cylindrical space with a large diameter to accommodate the motor 71. The inner surface of the upper half of the left shell connecting part 23 has a pair of reduction unit limiting parts 241, which are roughly cuboid in shape. A grid-like protrusion is formed on the inner surface of the housing between the pair of reduction unit limiting parts 241, and a reduction and torque amplification unit 72 with an I-shaped cross-section can be fitted between the pair of reduction unit limiting parts 231.

[0084] The inner surface of the lower main body 22 of the left shell has a circuit board receiving part 221 and a wire storage cavity 222.

[0085] Figure 13 yes Figure 8 A magnified view of the area inside frame C.

[0086] like Figure 13 As shown, the circuit board receiving part 221 includes a pair of circuit board fitting grooves 2211 and a pair of button unit limiting grooves 2212.

[0087] The circuit board fitting groove 2211 is a square groove with an opening on one side. The openings of a pair of circuit board fitting grooves 2211 face each other, and the two sides of the circuit board 81 in the width direction are respectively fitted into a pair of circuit board fitting grooves 2211. In this embodiment, the extension length of the circuit board fitting groove 2211 is approximately equal to the width of the circuit board 81, so that the circuit board 81 can be stably fitted into it.

[0088] The button unit limiting groove 2212 is an L-shaped groove, and the two sides of the power button unit 82 in the width direction are respectively placed on a pair of button unit limiting grooves 2212. The lower main body part 22 of the left shell also has a notch on the side facing the upper main body part 21 of the left shell, and the lower main body part 32 of the right shell also has a corresponding notch at the corresponding position. The power button unit 82 is exposed from the notch and is locked and limited by the pair of notches.

[0089] A wire storage cavity 222 is formed on one side of the circuit board receiving portion 221 for storing some wires. The wire storage cavity 222 has a hollow cylindrical protrusion 2221, and longer wires can be wound around the cylindrical protrusion 2221 for storage. The cylindrical protrusion 2221 is also used for mounting screws. There is a matching cylindrical protrusion at the corresponding position on the right housing 30.

[0090] Below the handle portion 23 of the left housing, near the lower main body portion 22 of the left housing, there is a wire fitting portion 233, used to fix multiple wires connecting the circuit board 81 and the micro switch. The wire fitting portion 233 includes multiple wire limiting protrusions 2331. In this embodiment, the wire limiting protrusions 2331 are cylindrical protrusions, and the five wire limiting protrusions 2331 are arranged in a straight line. The distance between two adjacent wire limiting protrusions 2331 is slightly smaller than the diameter of the wire, so that multiple wires can be fitted between two wire limiting protrusions 2331 for limiting and fixing. After the wires are inserted, they can be further bonded to the inner surface of the left housing 20 with white glue or the like above or below the wire fitting portion 233.

[0091] Based on the above structure, internal components such as microswitches, springs, and wires can be housed in the left housing 20, while the right housing 30 is only used for pressing and limiting, thus facilitating the assembly of the two housings.

[0092] Functions and effects of the embodiments

[0093] The nail gun 10 provided in this embodiment, which is easy to assemble, includes a left housing 20 and a right housing 30 that match each other and can be assembled into a whole housing. Since the receiving parts for accommodating the internal components of the nail gun 10 are all provided on the left housing 20, and the right housing 30 is only provided with a limiting part corresponding to the receiving part, and the internal components are all accommodated on the left housing 20, during assembly or disassembly and maintenance, it is only necessary to align and combine the right housing 30 with the outer contour of the left housing 20 that accommodates the internal components, without having to align and embed the other half of the internal components into the groove of another housing as in existing nail guns. Therefore, it is easier to assemble the left housing 20 and the right housing 30 together, thereby improving the user experience and increasing the efficiency of assembly and maintenance.

[0094] In this embodiment, the nail gun 10 has a nail-shooting switch 91, a protection switch 92, a safety switch 93, and an energy-storing stop switch 94. The internal components include a plurality of corresponding switching elements (microswitches) and a reset element (spring). The inner surface of the left housing 20 has a plurality of element fitting parts for fixing the microswitches and a spring for setting the spring. Each element fitting part includes a plurality of square columnar protrusions for limiting the side of the microswitches, and two cylindrical protrusions that pass through the mounting holes of the microswitches to fix them. This structure can keep the microswitches stable and does not require screws or other connecting parts to fix the microswitches, making installation more convenient and quick.

[0095] Furthermore, both the nail gun switch 91 and the safety switch 92 are located on the handle. The micro switch of the safety switch 92 is installed at an angle inside the handle, and its trigger spring is tilted upward. This allows the safety switch 92 to be positioned closer to the nail gun switch 91, which helps to shorten the stroke of the safety pressing part 921 and improve the sensitivity of the safety switch 92, thereby making it easier for the operator to operate and providing a better user experience.

[0096] In this embodiment, the internal components also include a circuit board 81 and multiple wires connected to it. The inner surface of the left housing 20 has a fitting groove for fitting and mounting the circuit board 81, as well as a wire storage cavity and a wire routing post for accommodating the wires. At the same time, multiple notches for wire routing are also provided on the grid-like protrusions on the inner surface of the housing. Therefore, the circuit board 81 and the wires can be stably installed in the housing, and the problem of poor wire contact or even falling off is not likely to occur during the nail shooting process.

[0097] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the scope of the description of the above embodiments.

[0098] In the above embodiment, the left housing 20 serves as a receiving housing with multiple receiving portions on its inner surface for receiving internal components, and the right housing 30 serves as a limiting housing with multiple corresponding limiting portions on its inner surface for limiting the internal components, thereby facilitating the assembly of the two housing halves. In an alternative solution, the design of the left and right housings can also be changed, i.e., the right housing 30 is provided with receiving portions and the left housing 20 is provided with limiting portions, which can also achieve the corresponding technical effect.

[0099] In the above embodiment, the extension length of the circuit board fitting groove 2211 is approximately equal to the width of the circuit board 81, so that the circuit board 81 can be stably fitted therein. In an alternative, the extension length of the circuit board fitting groove 2411 can also be shorter, greater than 2 / 3 of the width of the circuit board 81, so that the circuit board 81 is not easy to fall out.

[0100] In the above embodiments, the inner surfaces of the left housing 20 and the right housing 30 have strip-shaped protrusions, mesh-shaped protrusions, etc., for accommodating or limiting internal components. These structures also serve as reinforcing ribs on the inner surfaces of the housings, thereby strengthening the overall structural strength of the housings.
