[0029] like Figures 1-8 As shown, this utility model proposes a dustproof structure for a lithium-ion nail gun, including a mounting part 1, a locking crossbar 4, and a brush part 11.

[0030] The installation part 1 is installed on the gun shell 2, and the installation part 1 comprises an installation base plate 101 and a positioning cover plate 102.

[0031] The clamping cross rod 4 is slidably connected in the installation cavity 3, one end of the clamping cross rod 4 is provided with a limiting groove 5, a thimble 6 is slidably connected and embedded in the limiting groove 5, the installation base plate 101 is provided with a clamping hole 7 matched with the thimble 6, and the thimble 6 and the limiting groove 5 are connected with a spring 8, one side of the clamping cross rod 4 towards the positioning cover plate 102 is provided with a reset groove 9, and a sliding button 10 is slidably connected in the reset groove 9, and the sliding button 10 is fixed with the thimble 6. It should be noted that the sliding connection can be understood as that the clamping cross rod 4 can slide back and forth along the width direction of the front opening 3-1 to increase or restore the width of the front opening 3-1.

[0032] The brush part 11 comprises a connecting plate 1101 and brush hairs 1102, the connecting plate 1101 is fixed with the brush hairs 1102, the connecting plate 1101 can be inserted into the installation cavity 3 from the front opening 3-1, and the reset of the clamping cross rod 4 can limit the pulling out of the connecting plate 1101. It should be noted that the brush hairs 1102 should cover the striker 7, and especially the striker 7 needs to shuttle between the brush hairs 1102, and in specific implementation, only the length of the brush hairs 1102 needs to be matched with the internal space of the gun shell 2.

[0033] In the implementation of the dustproof structure of the lithium battery nail gun, the installation base plate 101 and the positioning cover plate 102 are first removed from the gun shell 2, then the installation base plate 101 and the positioning cover plate 102 are opened, the installation base plate 101 is taken out, then when the brush part 11 is replaced, the sliding button 10 can be slid first, the thimble 6 is driven to move towards the spring 8 and is separated from the clamping hole 7, then the clamping cross rod 4 can be pulled outwards to increase the size of the front opening 3-1 of the installation cavity 3, the connecting plate 1101 of the brush part 11 is inserted, then the clamping cross rod 4 is pushed back, the thimble 6 is reset under the action of the spring 8 and is inserted into the clamping hole 7, and the brush part 11 can be limited in the installation cavity 3. It can be seen that since the size of the front opening 3-1 can be adjusted, the whole installation process is more smooth and convenient, and even if the size of the brush part 11 is slightly larger, it will not affect the installation.

[0034] In the embodiment, the T-shaped sliding block 12 is fixed at both ends of the clamping cross rod 4, and the mounting base plate 101 is provided with a sliding rail groove 13 matched with the sliding block 12. The sliding block 12 is embedded and slidingly connected in the sliding rail groove 13, so that the sliding direction of the clamping cross rod 4 in the mounting cavity 3 is limited in the sliding rail groove 13. During the process of moving the clamping cross rod 4 by the operating knob 10 to adjust the opening size of the mounting cavity 3 to replace the brush part 11, the left and right shaking or deviation of the clamping cross rod 4 from the predetermined sliding track can be prevented. For example, in actual use, if there is no stable guiding structure, the clamping cross rod 4 may be tilted due to uneven force of the user during operation or slight external impact, so that the ejector pin 6 cannot accurately slide in the limiting groove 5 or cannot be smoothly matched with the clamping hole 7, thereby affecting the installation and disassembly of the brush part 11.

[0035] In the embodiment, the limiting plug-in part 14 is arranged on the side of the positioning cover plate 102 facing the mounting cavity 3, and includes a horizontal limiting plug-in part 14-1 and a vertical limiting plug-in part 14-2. The limiting plug-in part 14 can be inserted into and tightly connected with the connecting plate 1101 from the side opening 3-2 of the mounting cavity 3. Specifically, the horizontal limiting plug-in part 14-1 tightly presses the top of the connecting plate 1101, and the vertical limiting plug-in part 14-2 tightly presses the side of the connecting plate 1101, so as to limit the movement of the connecting plate 1101 and increase the stability of the brush.

[0036] Further, in the embodiment, in order to increase the friction between the connecting plate 1101 and the limiting plug-in part 14, or to reduce the gap between the connecting plate 1101 and the limiting plug-in part 14, and prevent the movement of the connecting plate 1101, the elastic gasket 15 is arranged at the bottom of the horizontal limiting plug-in part 14-1.

[0037] In the embodiment, the positioning hole 16 matched with the operating knob 10 is arranged on the positioning cover plate 102, and when the positioning cover plate 102 is covered on the mounting base plate 101, the operating knob 10 is embedded in the positioning hole 16 and the sliding of the operating knob 10 is limited. During the normal use of the lithium electric nail gun, if the operating knob 10 is not limited and slides randomly, the clamping cross rod 4 may be moved accidentally, thereby affecting the fixing state of the brush part 11. When the worker moves with the nail gun or performs other operations which are not for replacing the brush part 11, if the operating knob 10 is accidentally moved, the positions of the related components such as the ejector pin 6 and the clamping cross rod 4 will be changed, which may cause the brush part 11 to be loose or even fall off, thereby affecting the dustproof effect. The limiting effect of the positioning hole 16 on the operating knob 10 can effectively avoid such accidental operation, so that when the brush part 11 does not need to be adjusted, the whole dustproof structure is in a stable state, and the nail gun can work normally and reliably.

[0038] In the embodiment, the reset slot 9 is shorter than the slide button 10, the slide button 10 can cover the reset slot 9, the reset slot 9 is a part of the clamping cross rod 4 for slidingly connecting the slide button 10, in the actual use environment, there may be various dust, debris and other foreign matters, since the slide button 10 is longer than the reset slot 9 and can cover the reset slot 9, it is equivalent to providing protection for the reset slot 9, which can effectively prevent the dust, wood chips and other foreign matters from the outside from entering the reset slot 9, if the foreign matters enter the reset slot 9, it may affect the smooth sliding of the slide button 10 therein, cause the operation to be blocked, and even possibly damage the cooperation structure between the slide button 10 and the reset slot 9, by the mode, the probability of such situation can be reduced, and the normal operation of the internal structure is protected.

[0039] In the embodiment, the brush part 11 further comprises a plug-in part 1103, the bristles 1102 are fixed on the plug-in part 1103, and the connecting plate 1101 is provided with a plug-in slot for sliding the plug-in part 1103. The bristles 1102 may be worn, damaged and the like after long-term use, and need to be replaced, with the design of the plug-in part 1103 and the plug-in slot, when the bristles 1102 need to be replaced, the bristles 1102 with the plug-in part 1103 are pulled out of the plug-in slot, and then the plug-in part 1103 with new bristles 1102 is inserted, the operation is relatively simple and convenient, the whole brush part 11 does not need to be disassembled and reassembled, the efficiency of the maintenance work of replacing the bristles 1102 is greatly improved, and the use cost and maintenance difficulty are reduced.

[0040] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation, direct / indirect application in other related technical fields under the utility model concept of the utility model, and the contents of the utility model specification and drawings are included in the patent protection range of the utility model.
