Abstract

An energy storage mechanism and a nail gun having the same. The energy storage mechanism is coupled with a striking mechanism for striking nails out of the nail gun along a striking direction. The energy storage mechanism comprises an energy storage member comprising an air chamber for containing air; an inner cylinder body for installing the striking mechanism therein; and an outer cylinder arranged outside the inner cylinder, such that the air chamber is formed between the outer cylinder and the inner cylinder; an inflatable member disposed on the energy storage member and configured to inflate the air chamber; and a pressure relief member disposed on the energy storage member and configured to release the pressure in the air chamber.

Dependent claims

An energy storage mechanism used for a nail gun for nailing, coupled with a striking mechanism for striking nails out of the nail gun along a striking direction, comprising:

an energy storage member comprising an air chamber for containing air;
an inner cylinder body for installing the striking mechanism therein;
and an outer cylinder arranged outside the inner cylinder, such that the air chamber is formed between the outer cylinder and the inner cylinder;
an inflatable member disposed on the energy storage member and configured to inflate the air chamber;
and
a pressure relief member disposed on the energy storage member and configured to release the pressure in the air chamber,
wherein the outer cylinder comprises an outer cylinder body comprising a pressure relief port formed the front end of the outer cylinder body;
and a pressure relief channel connecting the pressure relief port and the air chamber;
and
wherein the pressure relief member is disposed on the front end of the outer cylinder body in fluidic communication with the air chamber, and comprises a pressure relief valve configured to be automatically opened to release the pressure in the air chamber when the pressure in the air chamber reaches a preset threshold value, and manually opened to discharge the air inside the air chamber before disassembly when the outer cylinder body needs to be maintained.

7 more elements

A nail gun, comprising:

a striking mechanism for striking nails out of the nail gun along a striking direction for nailing, wherein the striking mechanism comprises a plurality of tooth grooves;
an energy storage mechanism configured to provide energy to drive the striking mechanism to move in the striking direction, and store energy when the striking mechanism is driven to move in an opposite direction to the striking direction;
and
a transmission mechanism coupled with the energy storage mechanism and the striking mechanism for driving the striking mechanism to move in the opposite direction to the striking direction for storing energy, wherein the transmission mechanism comprises:
a rotating member configured to be driven by a driving motor to rotate, wherein the rotating member has a plurality of pin mounting holes, wherein the plurality of pin mounting holes comprises at least one movable pin mounting hole;
an engaging part arranged on the rotating member, wherein the engaging part comprises a plurality of engaging pins installed in the plurality of pin mounting holes, wherein the plurality of engaging pins comprises at least one movable engaging pin moveably installed in at least one movable pin mounting hole, and wherein two adjacent engaging pins define a gap therebetween;
and
an elastic assembly placed between the movable engaging pin and the rotating member, wherein the elastic assembly comprises a spring received in the at least one movable pin mounting hole with one end abutting against the movable engaging pin, and the other end abutting against the rotating member,
wherein during the rotation of the rotating member, the plurality of engaging pins is sequentially meshed with the plurality of tooth grooves of the striking mechanism to achieve an engagement between the transmission member and the striking mechanism.
