Description

Technical Field

[0001] This application relates to the field of electric nail gun technology, and in particular to a linkage device for an electric nail gun and an electric nail gun. Background Technology

[0002] The linkage device of an electric nail gun mainly includes a motor, a linkage mechanism, and a push rod. The motor's output is connected to the linkage mechanism, and the push rod is also connected to the linkage mechanism. The motor drives the linkage mechanism to move, causing the push rod to reciprocate in a set direction to clamp the nail. However, in practical applications, during the process of driving the push rod through the linkage mechanism, in addition to the force acting in the direction of the push rod's movement, there are also forces acting in the up, down, left, and right directions. This can cause the push rod to rotate or swing during use, affecting the stable clamping of the nail. Utility Model Content

The side plate portion is disposed on one side of the top plate portion perpendicular to the first direction. Both the top plate portion and the side plate portion have a first connecting hole.

[0027] The second connecting plate and the side plate form the guide groove. The second connecting plate is provided with a positioning protrusion that is adapted to the positioning hole. The positioning protrusion has a second connecting hole, which is connected to the first connecting hole by a fastener to fix the second connecting plate and the first connecting plate together.

[0029] The advantages or beneficial effects of the above technical solutions include at least the following:

[0030] The linkage device of this electric nail gun includes a base, a motor, a push rod, a linkage mechanism, and a limiting component. The motor drives the input end of the linkage mechanism to rotate, which in turn moves the output end of the linkage mechanism along a first direction. This movement, via the limiting component, pushes the push rod to move, enabling rapid nail clamping. During the movement of the limiting component at the second end of the linkage mechanism, the limiting component engages with a guide groove in the base to limit its movement, preventing the push rod from swaying or rotating and improving the stability and lifespan of the electric nail gun.

Detailed Implementation

[0049] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0050] See Figures 1-12 This invention illustrates a preferred embodiment of a linkage device for an electric nail gun, comprising:

[0051] The substrate 1 has a guide groove 14 extending along a first direction;

[0052] Motor 2, motor 2 is mounted on base 1;

[0053] Push rod 3 is movably mounted on base 1 along a first direction;

[0054] Linkage mechanism 4, the input end of linkage mechanism 4 is connected to the output end of motor 2, and the input end of linkage mechanism 4 can rotate with the output end of motor 2. The output end of linkage mechanism 4 is used to move along a first direction under the drive of motor 2; and

[0055] Limiting element 6 is provided on push rod 3 and is connected to the output end of linkage mechanism 4. Part of limiting element 6 is movably placed in guide groove 14.

[0056] The linkage device of this electric nail gun includes a base 1, a motor 2, a push rod 3, a linkage mechanism 4, and a limiting member 6. The motor 2 drives the input end of the linkage mechanism 4 to rotate, and the rotation of the input end of the linkage mechanism 4 drives the output end of the linkage mechanism 4 to move in a first direction. This causes the push rod 3 to move through the limiting member 6, achieving rapid nail clamping. During the movement of the limiting member 6 by the second end of the linkage mechanism 4, the limiting member 6 is partially engaged with the guide groove 14 of the base 1 to limit the movement of the limiting member 6, ensuring that the push rod 3 will not swing or rotate, thus improving the stability and service life of the electric nail gun.

[0057] Specifically, motor 2 can be either a brushed motor or a brushless motor.

[0058] See Figure 8 In one embodiment, the limiting member 6 is provided with a limiting part 61, which extends to at least one side relative to the first direction. The limiting part 61 is placed in the guide groove 14 and is slidably engaged with the guide groove 14. That is, the limiting part 61 is engaged with the guide groove 14 to realize the movement limiting and guiding of the limiting member 6, thereby realizing the movement limiting and guiding of the push rod 3, making the push rod 3 move more smoothly and stably.

[0059] See Figure 3 and Figure 8 In one embodiment, the limiting member 6 is provided with a trigger part 62;

[0060] The base 1 is equipped with a first sensor 7 and a second sensor 8. When the push rod 3 moves outward relative to the base 1 to a set position, the contact of the first sensor 7 cooperates with the trigger part 62 to trigger the first sensor 7, thereby stopping the motor 2 and limiting the position of the push rod 3 relative to the base 1. When the push rod 3 moves inward relative to the base 1 to a set position, the contact of the second sensor 8 cooperates with the trigger part 62 to trigger the second sensor 8, thereby stopping the motor 2 and limiting the position of the push rod 3 relative to the base 1. This achieves the limitation of the movement stroke of the push rod 3. When the push rod 3 moves to the set position, the trigger part 62 cooperates with the contact of the corresponding sensor to trigger the corresponding sensor, thereby causing the controller of the electric nail gun to control the motor 2 to automatically stop according to the feedback information of the sensor, thereby achieving accurate positioning of the push rod 3.

[0061] Both the first sensor 7 and the second sensor 8 can be contact sensors or non-contact sensors.

[0062] Of course, in other implementations, the electric nail gun may be equipped with only one sensor. In this case, the motor can be shut down by calculating the distance or time away from the sensor.

[0063] See Figure 8 and Figure 11 In one embodiment, the push rod 3 has a positioning groove 31;

[0064] The limiting member 6 is provided with a connecting part 63, which is adapted to the positioning groove 31 and is connected to the push rod 3. In this way, when installing the limiting member 6, the limiting member 6 is positioned by using the cooperation between the connecting part 63 and the positioning groove 31, and finally the connecting part 63 is fixed together with the push rod 3, which facilitates the quick and correct installation of the limiting member 6 onto the push rod 3.

[0065] See Figure 8 In one embodiment, the limiting part 61 is located above the trigger part 62, the connecting part 63 extends along the moving direction of the limiting member 6, and the connecting part 63, the limiting part 61, and the trigger part 62 are arranged in a cross shape, so that the limiting member 6 is formed into a cross-shaped structure.

[0066] See Figure 3 In one embodiment, the linkage device of the electric nail gun further includes:

[0067] The elastic element 9 has one end abutting against the base 1 and the other end abutting against the push rod 3. The elastic element 9 provides a driving force for the push rod 3 to move inward relative to the base 1. See also... Figure 4 When the push rod 3 is driven by the linkage mechanism 4 to move inward relative to the base 1 to the set position, the included angle between the first link 41 and the second link 42 in the linkage mechanism 4 is the smallest. The lateral force generated by the linkage of the first link 41 and the second link 42 on the push rod 3 is greater than the axial force. Since the elastic element 9 can provide the push rod 3 with the driving force to move inward relative to the base 1, it plays the role of increasing the axial force when the push rod 3 moves inward. It cooperates with the guide groove 14 to make the push rod 3 move inward more smoothly.

[0068] See Figure 3 In one embodiment, the elastic element 9 is sleeved on the outer peripheral wall of the push rod 3, and the push rod 3 guides the elastic element 9 so that the elastic element 9 can extend and retract more smoothly.

[0069] In one embodiment, the elastic element 9 can be a spring, or an elastic structure such as a sheet, elastic rubber element, or bellows, as long as it can provide the push rod 3 with a driving force to move inward relative to the base 1.

[0070] In one embodiment, the base 1 has a guide hole, through which the push rod 3 is movably inserted to guide its movement, making the push rod 3 move more smoothly and stably.

[0071] See Figure 2 In one embodiment, the linkage device of the electric nail gun further includes:

[0072] The anti-wear sleeve 10 is provided on the base 1. The anti-wear sleeve 10 has the above-mentioned guide hole. By providing the guide hole on the anti-wear sleeve 10, wear can be reduced, thereby effectively avoiding the problem of decreased accuracy caused by the movement and wear of the push rod 3, and enabling the push rod 3 to move more steadily and for longer.

[0073] In one embodiment, there are two anti-wear sleeves 10, which are spaced apart along the moving direction of the push rod 3.

[0074] In one embodiment, the anti-wear sleeve 10 is made of copper to give it better anti-wear performance, which can greatly improve its service life and reduce maintenance costs.

[0075] Of course, in other embodiments, the anti-wear sleeve 10 may also be a structure made of other materials with wear-resistant properties, such as stainless steel.

[0076] See Figure 2 In one embodiment, the linkage device of the electric nail gun further includes:

[0077] The reducer 20 is mounted on the base 1. The input end of the reducer 20 is connected to the output end of the motor 2, and the output end of the reducer 20 is connected to the input end of the linkage mechanism 4. The reducer 20 can reduce the speed and increase the torque, which can greatly improve the transmission stability and transmission efficiency. Therefore, it can efficiently and stably transmit the torque output from the motor 2 to the linkage mechanism 4, and then to the push rod 3 through the linkage mechanism 4.

[0078] See Figure 2 In one embodiment, the reducer 20 and the motor 2 are arranged side by side in the horizontal direction to improve the space utilization of the linkage device in the horizontal direction, so that the linkage device will not occupy too much space in one direction, thereby making it easier for the user to hold the electric nail gun.

[0079] In this context, it can be understood that the horizontal arrangement of the reducer 20 and the motor 2 means that the output shafts of the reducer 20 and the motor 2 are arranged horizontally side by side. (See also...) Figures 3-6 In one embodiment, the linkage mechanism 4 includes:

[0080] The first link 41 is connected to the output end of the reducer 20; and

[0081] The second link 42 has its first end rotatably connected to the first link 41, and its second end rotatably connected to the limiting member 6. Thus, the motor 2 drives the first link 41 to rotate, which in turn causes the second link 42 to swing, allowing its second end to reciprocate along a first direction. This, in turn, moves the push rod 3 along a set direction, achieving rapid clamping of the nail. Because the rotation of the motor 2's output is converted into linear motion through the linkage of the first and second links 41 and 42, this linear motion is relatively stable and does not cause a decrease in accuracy due to wear on the first and second links 41 and 42.

[0082] See Figures 13-14 In one embodiment, the first link 41 has a mounting hole 411;

[0083] The linkage mechanism of the electric nail gun also includes:

[0084] A coupling 60 is provided in the mounting hole 411 and has a coupling hole 601. The coupling hole 601 is adapted to the output end of the reducer 20 to connect the first connecting rod 41 and the output end of the reducer 20 together. That is, the output end of the reducer 20 and the first connecting rod 41 are connected by the coupling 60. The coupling 60 can also separate the output end of the reducer 20 from the first connecting rod 41, making it easier to disassemble and reassemble the output end of the reducer 20 and the first connecting rod 41 during later maintenance, thereby reducing the difficulty of maintenance.

[0085] See Figure 14 In one embodiment, the first connecting rod 41 is further provided with a positioning part 412, which is disposed on the wall of the mounting hole 411.

[0086] The outer peripheral wall of the coupling 60 has a positioning groove 602, which is adapted to the positioning part 412. That is, the positioning part 412 is inserted into the positioning groove 602 to position the coupling 60, restrict the coupling 60 from rotating relative to the first connecting rod 41, and ensure that the output end of the reducer 20 can efficiently transmit torque to the first connecting rod 41.

[0087] In one embodiment, there are two positioning parts 412 and two positioning slots 602. The two positioning parts 412 are respectively inserted into a corresponding positioning slot 602 to reliably limit the rotation of the coupling 60 relative to the first connecting rod 41.

[0088] In one embodiment, the linkage device of the electric nail gun further includes:

[0089] Bearing sleeve 90, the bearing sleeve 90 is disposed between the reducer 20 and the first connecting rod 41; and

[0090] Bearing 80 is located inside bearing sleeve 90;

[0091] The output end of the reducer 20 passes through the center hole of the bearing 80 and the bearing sleeve 90, and the inner ring of the bearing 80 can rotate with the output end of the reducer 20. In this way, the bearing 80 can be used to support and limit the output end of the reducer 20, which can reduce the sway of the output end of the reducer 20.

[0092] See Figure 14 In one embodiment, for ease of installation, the output end of the reducer 20 is provided with an output shaft 50, which passes through the center hole of the bearing 80 and the bearing sleeve 90, and is inserted into the coupling hole 601.

[0093] See Figure 14 For ease of installation, the linkage mechanism of the electric nail gun also includes:

[0094] The locking fastener 70 is located at the end of the output shaft 50 away from the reducer 20, and the locking fastener 70 can abut against the end of the coupling 60 away from the reducer 20 to prevent the output shaft 50 from disengaging from the coupling 60.

[0095] Of course, in other embodiments, the linkage mechanism 4 can be a flywheel structure or a structure with a swing arm and a groove.

[0096] See Figure 2 To simplify the machining of the guide groove 14, in one embodiment, the substrate 1 includes:

[0097] Main body 11, which supports motor 2 and push rod 3;

[0098] A first connecting plate 12 is separately disposed from the main body 11, and the first connecting plate 12 is disposed on the main body 11; and

[0099] The second connecting plate 13 is separately set from the first connecting plate 12, and the second connecting plate 13 and the first connecting plate 12 form a guide groove 14.

[0100] See Figure 9 and Figure 10 In one embodiment, the first connecting plate 12 is provided with a top plate portion 121 and a side plate portion 122. The top plate portion 121 is connected to the main body 11 and has a positioning hole 1211. The side plate portion 122 is provided on one side of the top plate portion 121 perpendicular to the first direction. Both the top plate portion 121 and the side plate portion 122 have a first connecting hole.

[0101] The second connecting plate 13 and the side plate portion 122 form a guide groove 14. The second connecting plate 13 is provided with a positioning protrusion 131, which is adapted to a positioning hole 1211. The positioning protrusion 131 has a second connecting hole, which is connected to the first connecting hole by a fastener to fix the second connecting plate 13 and the first connecting plate 12 together. In this way, the positioning protrusion 131 and the positioning hole 1211 can be used to install and position the second connecting plate 13, which facilitates the quick and correct installation of the second connecting plate 13 onto the first connecting plate 12, greatly improving installation efficiency. At the same time, the fasteners can be used to connect the first connecting hole and the second connecting hole to reliably fix the first connecting plate 12 and the second connecting plate 13 together, resulting in high connection stability.

[0102] See Figure 12 In one embodiment, the linkage device of the electric nail gun further includes:

[0103] The transmission mechanism 30 has its input end connected to the output end of the motor 2, and its output end can rotate with the input end of the transmission mechanism 30. The output end of the transmission mechanism 30 is connected to the input end of the reducer 20 so that the torque of the motor 2 can be transmitted to the input end of the reducer 20 through the transmission mechanism 30.

[0104] See Figure 12 In one embodiment, the transmission mechanism 30 includes:

[0105] The drive gear 301 is sleeved on the output end of the motor 2 and can rotate with the output end of the motor 2.

[0106] Driven gear 302 and driving gear 301 are arranged side by side in the horizontal direction. Driven gear 302 meshes with driving gear 301 and is connected to the input end of reducer 20. That is, transmission mechanism 30 is a gear mechanism. Gear mechanism has the advantages of maintaining accurate transmission ratio, large speed range, high transmission efficiency, long service life, compact structure, small size and reliable operation. It can improve the transmission efficiency of power device while reducing the space occupied, so that the overall structure of power device is more compact and occupies less space.

[0107] See Figure 2 and Figure 12 In one embodiment, the transmission mechanism 30 further includes:

[0108] An intermediate gear 303 is rotatably mounted on the motor mounting housing 40. The intermediate gear 303 is located between the driving gear 301 and the driven gear 302, with the driving gear 301 meshing with the driven gear 302 via the intermediate gear 303. Because the driving gear 301 meshes with the driven gear 302 via the intermediate gear 303, the power of the driving gear 301 can be transmitted to the driven gear 302. Simultaneously, since the intermediate gear 303 is rotatably mounted on the base 1, it can support both the driving gear 301 and the driven gear 302, improving the assembly stability of the driving gear 301 and the driven gear 302, thereby further improving the transmission efficiency of the transmission mechanism 30.

[0109] Of course, in other embodiments, the transmission mechanism 30 may also adopt a chain drive mechanism 30, belt drive mechanism 30 or other transmission structures.

[0110] In one embodiment, the motor mounting housing 40 has a receiving cavity, in which the transmission mechanism 30 is disposed to accommodate the transmission mechanism 30. This not only improves the utilization rate of the internal space of the motor mounting housing 40, but also protects the transmission mechanism 30.

[0111] See Figure 1 A preferred embodiment of this utility model provides an electric nail gun, including the aforementioned linkage device for the electric nail gun.

[0112] The electric nail gun of this utility model, due to the adoption of the above-mentioned linkage device, also achieves the limitation of the limit member 6 by the cooperation of the limit member 6 part with the guide groove 14 of the base 1 during the movement of the second end of the linkage mechanism 4, thus ensuring that the push rod 3 will not swing or rotate, thereby improving the stability and service life of the electric nail gun.
