BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 The utility model is a schematic diagram of the overall structure of a protective structure of a sealing ring of a lithium-powered nail gun.
[0014] In the figure: 1. Piston; 2. Retaining ring; 3. Sealing ring; 4. Strike pin. DETAILED DESCRIPTION
[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0016] like Figure 1 As shown, a protective structure for a sealing ring of a lithium-ion nail gun includes a piston 1, a sealing groove is provided on the outer side of the piston 1, a sealing ring 3 is installed on the inner side of the sealing groove, a retaining ring 2 is installed on the inner wall of the inner side of the sealing groove, a firing pin 4 is installed on the inner side of the piston 1, and the outer diameter of the retaining ring 2 is greater than the outer diameter of the piston 1.
[0017] In this embodiment, the main material of the retaining ring 2 is rubber, the main material of the sealing ring 3 is rubber, there are two groups of retaining rings 2, both groups of retaining rings 2 are installed on the inner wall of the sealing groove, the two groups of retaining rings 2 clamp the sealing ring 3 in the middle, and the cross-section of the sealing ring 3 is X-shaped.
[0018] Specifically, during the movement of the piston 1, the sealing ring 3 is subjected to pressure, so that the sealing ring 3 contacts the retaining ring 2 in the sealing groove, and the gas pushes the retaining ring 2 to resist the sealing ring 3, so that the two groups of retaining rings 2 clamp the sealing ring 3, thereby reducing the sealing ring 3 from moving out of the sealing groove. By installing two groups of retaining rings 2 on the inner wall of the inner side of the sealing groove, and the sealing ring 3 is located between the two groups of retaining rings 2, the purpose of the sealing ring 3 being resisted by the retaining ring 2 can be achieved, and the sealing ring 3 is reduced from being clamped in the gap between the piston and the inner wall of the cylinder during the movement, thereby reducing the cylinder leakage caused by damage to the sealing ring 3 during the movement, and can improve the pressure bearing capacity of the sealing ring 3 and prevent it from being squeezed out of the sealing groove, so as to reduce the damage of the sealing ring 3 due to pressure during the movement, thereby effectively extending the service life.
[0019] In this embodiment, the piston 1 is circular in shape, and the axis lines of the piston 1 and the striker 4 are located on the same straight line.
[0020] Specifically, by locating the axis lines of the piston 1 and the striker 4 on the same straight line, the piston 1 can facilitate the striker 4 to move.
[0021] Working principle:
[0022] During use, during the use of the lithium-ion nail gun, due to the high-pressure working condition, the piston 1 drives the firing pin 4 to move. During the movement of the piston 1, the sealing ring 3 is subjected to pressure, so that the sealing ring 3 contacts the retaining ring 2 in the sealing groove. The gas pushes the two groups of retaining rings 2 against the sealing ring 3, so that the two groups of retaining rings 2 clamp the sealing ring 3, thereby reducing the movement of the sealing ring 3 out of the sealing groove. By installing two groups of retaining rings 2 on the inner wall of the inner side of the sealing groove, the sealing ring 3 is located between the two groups of retaining rings 2, so that the sealing ring 3 will be sandwiched in the middle by the retaining ring 2, reducing the sealing ring from being sandwiched in the gap between the piston body and the inner wall of the cylinder, thereby causing the sealing ring to be damaged and affecting the air tightness of the cylinder, effectively improving the pressure bearing capacity of the sealing ring 3 and preventing the probability of squeezing out of the sealing groove, so as to reduce the damage of the sealing ring 3 due to pressure during movement, thereby effectively extending the service life.
