Description

Technical Field

[0001] The utility model relates to the field of manual nail guns, in particular to a nailing output structure of a manual nail gun. Background Art

[0002] There are three main types of nailing force on the manual nail guns on the market, namely:

[0003] 1. Use leaf spring to pull the punch and release it instantly;

[0004] 2. Use torsion spring to drive the punch and release it instantly;

[0005] 3. Use compression spring, release instantly.

[0006] Before nailing, you need to manually overcome the force of the leaf spring, torsion spring or compression spring to store energy and then release it. This operation is very laborious, and after nailing several times in a row, your arms will feel sore, which makes the user experience poor and the nailing efficiency low. Utility Model Content

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a nailing force output structure of a manual nail gun, which realizes the characteristics of small handle pressing force and large nailing force.

[0008] The purpose of this utility model is to achieve the following technical solutions: the nailing output structure of this manual nail gun includes:

[0009] The housing has a nail feeding assembly on one side of the housing, a nail feeding guide rail on the top of the nail feeding assembly, and a punching guide rail facing the nail feeding guide rail.

[0010] The punch is relatively slidably mounted in the punch guide rail, and one end of the punch is aligned with the nail feeding guide rail, and is used to selectively extend into the nail feeding assembly to strike nails. Punch seats are fixed on both sides of the punch, and corresponding positions on the punch and the punch seat are provided with sliding grooves for inserting the movable pin. The end of the punch away from the nail feeding guide rail is provided with a socket;

[0011] Two tension springs are symmetrically arranged on both sides of the punching plate, and one end of each tension spring is fixedly connected to the housing, and the other end of the tension spring is connected to the movable pin, so that both ends of the movable pin are connected to a tension spring;

[0012] A transmission member is slidably disposed in the housing, a tongue is provided at the rear end of the transmission member for inserting into the socket of the punching sheet, a toggle protrusion is provided on the surface of the transmission member, and a matching inclined surface is provided on the side wall of the transmission member; and

[0013] The handle includes a connecting rod and a toggle rod rotatably connected to the housing, wherein the end of the toggle rod is aligned with and snapped into the toggle protrusion;

[0014] When the handle is pressed, the toggle rod drives the transmission part to slide in the direction away from the nail feeding guide rail, and simultaneously drives the punch to slide until the matching inclined surface contacts and slides with the shell inclined surface set on the inner wall of the shell, so that the tongue disengages from the socket, releasing the punch and extending it into the nail feeding guide rail to complete the nailing; when the handle is released, the return spring pushes the transmission part, so that the transmission part and the handle return to their original position.

[0015] As a further technical solution, a transmission guide rail is arranged on the outer surface of the transmission part, and a limit groove is opened on the transmission part along its sliding direction. After the guide rail fixing pin passes through the transmission guide rail and the limit groove in sequence, it is positioned with the guide rail fixing hole reserved on the shell. When the transmission part slides relative to the shell, the sliding stroke is limited by the limit groove. When the transmission part moves downward to the extreme position, the matching inclined surface contacts and slides with the inclined surface of the shell, driving the transmission part to rotate around the guide rail fixing pin in the direction away from the punching sheet, and the tongue and the socket are immediately disengaged.

[0016] As a further technical solution, a return spring seat is provided on the shell, and a spring locating pin is provided on the lower end surface of the transmission member. One end of the return spring is installed in the return spring seat, and the other end is against the lower end surface of the transmission member and is positioned by the spring locating pin.

[0017] As a further technical solution, a stop portion is provided on the housing on both sides of the punching sheet guide rail for stopping the punching sheet seat, thereby limiting the return stroke of the punching sheet.

[0018] As a further technical solution, the end of the tension spring is positioned in the housing by a tension spring fixing pin.

[0019] As a further technical solution, the ends of the tongue and the punch are both provided with inclined surfaces, so that the transmission member passes over the inclined surface of the punch when returning to its position, ensuring that the tongue is locked into the socket.

[0020] As a further technical solution, the connecting rod and the toggle rod of the handle are both provided with rotating pins, and corresponding positioning columns are provided on the shell. The connecting rod and the toggle rod are rotatably connected to the corresponding positioning columns through the rotating pins.

[0021] As a further technical solution, a notch is provided at the end of the toggle rod for aligning with the toggle protrusion on the transmission member.

[0022] The beneficial effects of the utility model are:

[0023] 1. When the handle is pressed, the punch moves backward through the transmission part, and then drives the tension spring, which is released instantly to generate power to knock out the nail. The operation no longer feels strenuous.

[0024] 2. The transmission member drives the punch to move backward, and the punch drives the tension spring to generate tension. When the transmission member moves to the limit position, the matching inclined surface contacts and slides with the inclined surface of the housing, driving the transmission member to rotate slightly around the guide rail fixing pin in the direction away from the punch. The tongue and the socket are then disengaged, realizing the separation of the transmission member and the punch. The punch is released instantly, generating power.

[0025] 3. Use the pressing handle to rotate, drive the toggle rod to rotate, the toggle rod rotates to drive the transmission part to move downward, and then the transmission part drives the punch to move backward. The overall transmission is more efficient, convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is a detailed introduction to the present invention with reference to the accompanying drawings:

[0038] Example: As shown in the attached Figures 1 to 8 As shown, the nailing output structure of this manual nail gun includes a shell 1, a tension spring 2, a movable pin 3, a punch 4, a punch seat 5, a tension spring fixing pin 6, a transmission part 7, a limiting groove 8, a toggle protrusion 9, a tongue 10, a spring positioning pin 11, a return spring 12, a transmission guide rail 13, a guide rail fixing pin 14, a guide rail fixing hole 15, a punch guide rail 16, a stopper 17, a slide groove 18, a socket 19, a nail feeding assembly 20, a nail feeding guide rail 21, a positioning column 22, a handle 23, a connecting rod 24, a toggle rod 25, a rotating pin 26, a notch 27, a return spring seat 28, a slope 29, a shell slope 30 and a matching slope 31.

[0039] Reference Attachment Figure 1 A nail feeding assembly 20 is provided on one side of the housing 1, a nail feeding guide rail 21 is provided on the top of the nail feeding assembly 20, and a punching guide rail 16 facing the nail feeding guide rail 21 is also provided on the housing 1. Figure 2a 、 2b As shown, a housing inclined surface 30 is provided on the housing 1 near the return spring seat 28 .

[0040] like Figure 1 、 5 As shown, the punching sheet 4 is relatively slidably installed in the punching sheet guide rail 16, and one end of the punching sheet 4 is aligned with the nail feeding guide rail 21, which can selectively extend into the nail feeding assembly 20 and hit the nail. The punching sheet seat 5 is fixed on both sides of the punching sheet 4 by threaded connection, and a slide groove 18 is provided at the corresponding position on the punching sheet 4 and the punching sheet seat 5. A movable pin 3 is inserted into the slide groove 18, as shown in FIG. Figure 3 As shown, a socket 19 is provided at one end of the punch 4 away from the nail feeding guide rail 21 .

[0041] Reference Attachment Figure 1, two tension springs 2 are symmetrically arranged on both sides of the punching piece 4, and one end of each tension spring 2 is fixed on the housing 1 through the tension spring fixing pin 6, and the other end of the tension spring 2 is connected to the movable pin 3, so that both ends of the movable pin 3 are connected to a tension spring 2. Figure 4a 、 4b 5, the transmission member 7 is relatively slidably arranged in the housing 1, and the rear end of the transmission member 7 is provided with a tongue 10, which can be inserted into the socket 19 of the punch 4, as shown in FIG. Figure 1 As shown, a return spring 12 is provided between the lower end surface of the transmission member 7 and the inner wall of the housing 1. Preferably, a return spring seat 28 is provided on the housing 1, and a spring positioning pin 11 is provided on the lower end surface of the transmission member 7. One end of the return spring 12 is installed in the return spring seat 28, and the other end is against the lower end surface of the transmission member 7 and is positioned by the spring positioning pin 11. A toggle protrusion 9 is also provided on the surface of the transmission member 7, and a matching inclined surface 31 is provided on the side wall of the transmission member 7. Figure 4a 、 4b shown.

[0042] like Figure 6 、 7 As shown in FIG8 , a connecting rod 24 and a toggle rod 25 are fixedly mounted on the handle 23. Both the connecting rod 24 and the toggle rod 25 of the handle 23 are provided with a rotating pin 26. Figure 2a As shown, a positioning column 22 is correspondingly provided on the housing 1, and the connecting rod 24 and the toggle rod 25 are rotatably connected to the corresponding positioning column 22 through a rotating pin 26. A notch 27 is provided at the end of the toggle rod 25, which can be aligned with the toggle protrusion 9 on the transmission member 7.

[0043] like Figure 7 As shown, when the handle 23 is pressed, the toggle rod 25 is used to drive the transmission member 7 to slide away from the nail feeding guide rail 21, and the punch 4 is simultaneously driven to slide until the matching inclined surface 31 contacts and slides with the shell inclined surface 30 set on the inner wall of the shell 1, so that the tongue 10 is separated from the socket 19, and the punch 4 is released and extends into the nail feeding guide rail 21 to complete the nailing. Figure 8 As shown, when the handle 23 is released, the return spring 12 pushes the transmission member 7, causing the transmission member 7 and the handle 23 to return to their original positions.

[0044] For further information, see the attached Figure 5A transmission guide rail 13 is provided on the outer surface of the transmission member 7, and a limit groove 8 is provided on the transmission member 7 along its sliding direction. After the guide rail fixing pin 14 passes through the transmission guide rail 13 and the limit groove 8 in sequence, it is positioned with the guide rail fixing hole 15 reserved on the housing 1, and the transmission guide rail 13 is also fixed. When the transmission member 7 slides relative to the housing 1, the sliding stroke is limited by the limit groove 8. When the transmission member 7 moves downward to the limit position, the matching inclined surface 31 contacts and slides with the inclined surface 30 of the housing, driving the transmission member 7 to rotate slightly around the guide rail fixing pin 14 in the direction away from the punching sheet 4 by a certain angle, and the tongue 10 is immediately disengaged from the socket 19. Figure 7 shown.

[0045] Preferably, if Figure 2a As shown, a stopper 17 is provided on the housing 1 on both sides of the punching guide rail 16, which can stop the punching seat 5, thereby limiting the return stroke of the punching sheet 4. Figure 3 As shown in Figures 4 and 5, inclined surfaces 29 are provided at the ends of the tongue 10 and the punch 4, so that the transmission member 7 passes over the inclined surface 29 of the punch 4 when returning to its position, ensuring that the tongue 10 can be smoothly inserted into the socket 19.

[0046] The working process of this utility model:

[0047] The handle 23 (toggle rod 25) is used to drive the transmission member 7 to slide along the transmission guide rail 13, and synchronously drive the punch 4 to move backward. A punch seat 5 is fixed on the punch 4, and a movable pin 3 is inserted into the punch seat 5. The movable pin 3 is connected to one end of the tension spring 2. When moving backward, the tension spring 2 is driven to stretch. When it reaches the highest point, the clutch mechanism (i.e., the socket 19 and the tongue 10) separates the transmission member 7 from the punch 4. Under the action of the tension spring 2, the punch 4 is instantly released, generating power. The punch 4 extends into the nail feeding guide rail 21 and hits the nail in the nail feeding assembly 20.

[0048] When the handle 23 is pressed and rotated, the toggle rod 25 is driven to rotate, and the rotation of the toggle rod 25 drives the transmission member 7 to move downward, and the transmission member 7 drives the punching piece 4 to move backward. The punching piece 4 stretches the connecting tension spring 2. When it reaches the set highest point, the guide rail fixing pin 14 contacts the upper end of the limit groove 8. At this time, the matching inclined surface 31 contacts and slides with the inclined surface 30 of the shell, driving the transmission member 7 to rotate slightly around the guide rail fixing pin 14 in the direction away from the punching piece 4 by a certain angle, and the tongue 10 and the socket 19 are immediately disengaged, and the transmission member 7 is separated from the punching piece 4 (such as Figure 7 As shown). The punch 4 is released instantly, generating power to drive the nail out. Subsequently, the return spring 12 presses the transmission member 7 back to its original position and connects with the punch 4. When returning to its original position, the transmission member 7 passes over the inclined surface 29 of the punch 4, ensuring that the tongue 10 can be smoothly inserted into the socket 19. The handle 23 also returns to its original position. Figure 8 As shown, a nailing action cycle is completed.

[0049] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
