Abstract

A high-strength lithium battery nail gun with a composite energy storage structure is provided, which includes a gun body (1) having a tail section provided with an energy storage structure. The energy storage structure includes a spring compressing mechanism (2) and a vacuum cylinder mechanism (3). The spring compressing mechanism (2) includes a compression cavity (21), a spring (22), a spring piston (23) and a working piston rod (24). The spring (22) and the spring piston (23) are mounted in the compression cavity (21). A front end of the spring piston (23) is connected to the working piston rod (24). The lower part of the working piston rod (24) is provided with an upper rack structure (241). The vacuum cylinder mechanism (3) includes a cylinder (31) and a cylinder piston (32). A completely sealed vacuum chamber (3a) is formed by the cylinder piston (32) and a tail end part of the cylinder (31). The upper side of the vacuum cylinder piston rod (33) is provided with a lower rack structure (331). The lower rack structure (331) is in engaged transmission with the upper rack structure (241) through a transmission gear (5). Through the energy storage structure, the spring compressing mechanism (2) and the vacuum cylinder mechanism (3) are organically combined into a whole body, so that the energy storage strength can be multipled, and the axial and radial vibration at the end of nailing can be effectively reduced.

A high-strength lithium battery nail gun with a composite energy storage structure, comprising a gun body (1) having a tail section of the gun body (1) provided with an energy storage structure, wherein the energy storage structure comprises a spring compressing mechanism (2) and a vacuum cylinder mechanism (3) linked with each other;

wherein the spring compressing mechanism (2) comprises a compression cavity (21), a spring (22), a spring piston (23) and a working piston rod (24), the spring (22) and the spring piston (23) are mounted in the compression cavity (21), a tail end of the spring (22) abuts against a bottom of the compression cavity (21), a front end of the spring (22) abuts against the spring piston (23) for connection, and the spring (22) has a precompression amount in an initial state so that the spring piston (23) always has a forward moving trend;
a front end of the spring piston (23) is connected to the working piston rod (24) for driving a gun needle (4) to work synchronously, and a lower part of the working piston rod (24) is provided with an upper rack structure (241);
the vacuum cylinder mechanism (3) comprises a cylinder (31) and a cylinder piston (32) arranged in the cylinder (31), a completely sealed vacuum chamber (3a) is formed by the cylinder piston (32) and a tail end part of the cylinder (31), the cylinder piston (32) is located at a tail section of the cylinder (31) in an initial state, a front end of the cylinder piston (32) is connected to a vacuum cylinder piston rod (33) extending out of the cylinder (31), an upper side of the vacuum cylinder piston rod (33) is provided with a lower rack structure (331), and the lower rack structure (331) is in engaged transmission with the upper rack structure (241) through a transmission gear (5) fixed on the gun body (1);
and a front end of the vacuum cylinder piston rod (33) is provided with a transmission structure to be in transmission connection with a driving mechanism (7).
