Description

Technical Field

[0001] The utility model relates to the field of double PIN connection of a striker piston, in particular to a connection structure for a striker piston. Background Art

[0002] A piston with a dual pin connector is usually used in a pneumatic or hydraulic system. It has two fixed pins (PIN) for connecting other mechanical parts. This design increases the flexibility and application range of the piston.

[0003] The connection method between the firing pin and the piston of existing nail gun tools is often a threaded connection or a single PIN connection. Generally speaking, the production cost of the threaded connection structure is relatively high (especially the firing pin), the strength of the single PIN connection structure may be insufficient, and in the existing single PIN connection structure between the firing pin and the piston, it is not easy to disassemble the firing pin and the piston. When in use, it is often necessary to align the positions of the firing pin and the piston before installing the firing pin, which is inconvenient to use.

[0004] Therefore, it is necessary to provide a new connection structure for the striker piston to solve the above technical problems. Utility Model Content

[0026] In the specific implementation process, Figures 1 to 6 As shown, it includes a striker 1, a piston 2 and a fixing mechanism, and the striker 1 is connected to the piston 2 through the fixing mechanism;

[0027] The fixing mechanism includes a slide plate 3, a fixing plate 32, a mounting plate 4 and a cylindrical pin 5. One side of the fixing plate 32 is fixed to the top of the piston 2. The slide plate 3 is slidably arranged on the other side of the fixing plate 32. The mounting plate 4 is fixed to the side of the fixing plate 32 away from the piston 2. The cylindrical pin 5 is inserted between the slide plate 3 and the mounting plate 4. The fixing plate 32 and the mounting plate 4 are arranged in parallel.

[0028] Specifically, a fixing plate 32 is provided on the top of the piston 2, and a slide plate 3 and a mounting plate 4 are provided on the other end of the fixing plate 32. The slide plate 3 can slide on one side of the fixing plate 32. When in use, the slide plate 3 is first moved up, and the striker 1 is inserted between the slide plate 3 and the mounting plate 4. The slide plate 3 is pressed downward to limit the striker 1. At this time, the cylindrical pin 5 is inserted between the slide plate 3 and the mounting plate 4 to fix the striker 1. The double PIN connection can maintain high connection strength and guidance, and is not prone to breakage.

[0029] refer to Figures 1 to 3 As shown, the surfaces of the slide plate 3 and the mounting plate 4 are provided with relatively distributed slots 311, the inner sides of the slide plate 3 and the mounting plate 4 are provided with a plurality of mounting slots 31, the plurality of slots 311 are communicated with the interiors of the plurality of mounting slots 31, a striker 1 is provided between the plurality of mounting slots 31, and a plurality of cylindrical pins 5 are inserted into the plurality of slots 311;

[0030] Specifically, a plurality of cylindrical pins 5 are inserted into a plurality of slots 311, the number of cylindrical pins 5 is the same as the number of slots 311, and the plurality of slots 311 are equidistantly distributed. The equidistant distribution allows the cylindrical pins 5 to fix the striker 1 when inserted into the slots 311, so that the striker 1 is better fixed. When the entire device is in use, the connection between the striker 1 and the piston 2 is not easy to break and has higher stability.

[0031] refer to Figures 4 to 6 As shown, a plurality of slide grooves 321 are provided on the surface of the fixed plate 32, and the slide plate 3 slides on the surfaces of the plurality of slide grooves 321. The establishment of the plurality of slide grooves 321 can facilitate the slide plate 3 to slide in the slide grooves 321. Preferably, a limiting groove is provided in the slide groove 321, so that the slide plate 3 can only move in the vertical direction during the sliding process, and will not deviate in the horizontal direction; a plurality of sliding blocks 322 are fixed to the bottom of the slide plate 3, and the plurality of sliding blocks 322 slide in the plurality of slide grooves 321. The size of the sliding block 322 matches the size of the slide groove 321. When in use, the bottom of the sliding block 322 slides in the limiting groove;

[0032] One end of the striker 1 is also provided with a plurality of insertion holes, which correspond to the positions of the plurality of slots 311, and the cylindrical pin 5 passes through the plurality of insertion holes and extends to the other end of the mounting plate 4;

[0033] Specifically, when in use, the striker 1 is inserted into the mounting groove 31. When the bottom of the striker 1 is in contact with one side of the fixing plate 32, the positions of the plurality of holes just correspond to the positions of the plurality of slots 311, and the mounting groove 31 will limit the striker 1 placed therein. There is no need to manually align the positions of the striker 1, the slide plate 3 and the mounting plate 4. The striker 1 can be directly inserted into the mounting groove 31. The piston 2 is made of aluminum alloy, and the striker 1 is flat. Preferably, one end of the cylindrical pin 5 is limited. When the cylindrical pin 5 is inserted into the slot 311, the other end fixes the cylindrical pin 5 in the slot 311 by snapping. In addition, the sealing plug in the piston 2 is made of rubber.

[0034] The working principle provided by the utility model is as follows: when in use, it is only necessary to move the slide plate 3 upwards, insert the striker 1 into the mounting groove 31, and then insert the cylindrical pin 5 from the slot 311 between the slide plate 3 and the mounting plate 4 to complete the fixation. When disassembling, it is only necessary to pull the cylindrical pin 5 out of the slot 311.
