Description

Technical Field

[0001] The invention relates to a technology in the field of nail guns, in particular to a new type of nail gun. Background Art

[0002] The electric nail guns and nail guns on the market use simple linear motors (this article uses subdivided voice coil motors) or electromagnets to drive the iron core to hit the nail to complete the nailing after power is turned on. This structure usually requires the motor, ejection mechanism and iron core to be arranged in the same direction or in parallel. Although the above arrangement structure is simple, the head size is large and the weight is heavy, which limits the user's operation in a small space. This also makes it difficult for electric nail guns to match the effect and life of pneumatic nail guns. At the same time, because the center of gravity is at the front, it is easy to cause user fatigue and deformation of movements, affecting work efficiency and nailing effect. In addition, some pneumatic nail guns also have the problem of large head size and heavy weight.

[0003] Patent CN105082065B discloses an electromagnetic nail gun that uses a lever acceleration structure to drive nails, which can greatly increase the speed of nailing. However, it brings two problems: one is that the head is large in size, and the other is that the striking force is reduced, which is prone to nail popping problems (nails cannot be driven into place). In order to drive into place, it is necessary to increase the power, which requires high power and increases costs. Other nail guns that use a rocker bearing or an eccentric rotating structure to achieve the up and down movement of the punch also have the above disadvantages. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a new type of nail gun, which connects the nail gun punch and the power component through a connecting rod structure, solves the problem of bulky structure of the nail gun head, reduces restrictions on the working space, and improves the comfort of use.

[0005] The present invention is achieved through the following technical solutions:

[0006] The present invention comprises: a punch mechanism, a power mechanism and a nail clamp, wherein the punch mechanism is arranged above the nail outlet of the nail clamp;

[0007] The punch mechanism is provided with a punch, and the punch is arranged on the carrier;

[0008] The power mechanism is provided with a driver, the output end of the driver is connected to a linear displacement actuator, and the linear displacement actuator is connected to the bearing member through a first connecting rod; the driver drives the linear displacement actuator to move, driving the punch to press down and nail.

[0009] The power mechanism is arranged on the handle of the nail gun; preferably, the angle between the linear displacement actuator and the movement direction of the punch is 90°±15°; further preferably, the movement direction is vertical.

[0010] A return spring is arranged at the front or rear of the linear displacement actuator along the moving direction.

[0011] A buffer is provided at the tail of the linear displacement actuator and / or the tail of the nail gun handle; preferably, the buffer is a buffer pad.

[0012] The handle of the nail gun is provided with a guide rail corresponding to the linear displacement actuator. The guide rail can reduce the sliding friction of the linear displacement actuator on the one hand, and can also limit the linear displacement actuator on the other hand.

[0013] Preferably, the guide rail adopts any one of a groove member, a pipe member and a sliding bearing with a low friction coefficient that matches the shape of the linear displacement actuator.

[0014] The punch mechanism is arranged at the head of the casing; preferably, the head of the casing is provided with a U-shaped guide rail, the bearing member is arranged on the U-shaped guide rail and connected to the first connecting rod through a rolling bearing; the rolling bearing is against the side edges of the U-shaped guide rail; preferably, the U-shaped guide rail adopts a rectangular guide rail.

[0016] Preferably, the bearing member adopts a piston structure and is arranged in the housing head; the housing head is provided with an exhaust hole at the bottom, and the piston is provided with a sealing ring corresponding to the exhaust hole.

[0017] Preferably, the bearing member is connected to a second connecting rod, one end of the second connecting rod is hinged to the first connecting rod, and the other end is hinged to the swing rod; the second connecting rod and the swing rod are arranged on the upper part of the casing head.

[0018] Technical Effects

[0019] Compared with the prior art, the present invention connects the nail gun punch and the power component through a connecting rod structure, thereby solving the problem of bulky structure of the nail gun head, reducing restrictions on the working space, and improving comfort of use; compared with ordinary nail guns, the present invention has the advantage of motion acceleration. During the downward pressing process of the punch, as the rotation angle of the connecting rod increases, the component force output to the punch part becomes larger and larger, and the punch movement speed becomes faster and faster relative to the constant power output of the driver.
