Description

Technical Field

[0001] The utility model relates to the technical field of striking tools, in particular to an insulation nail striking tool based on air power. Background Art

[0002] The traditional domestic insulation nail guns currently use gas (or gunpowder or air compressor, etc.) as a power source to drive the nails so that the nails are driven into the insulation layer of the building's exterior wall. However, these three power sources all have disadvantages:

[0003] 1) The gas-powered method is to inject a certain amount of gas into the combustion chamber of the nail gun, and then press the trigger to ignite the gas, which explodes to generate thrust to drive the nail out. This gas explosion method will produce a large amount of carbon deposits. After hitting about 1,000 nails, the cylinder of the nail gun will have difficulty continuing to work due to the accumulation of carbon deposits. After the carbon deposits accumulate, the piston will not be lubricated, and then the ignition will fail. In addition, there is insufficient power, and the nail cannot be driven to the expected depth. At this time, the cylinder of the nail gun must be disassembled and cleaned, which is time-consuming and laborious.

[0004] 2) The disadvantage of the gunpowder-powered method is that the gunpowder itself is very easy to explode during transportation. There is no suitable way to store the gunpowder and nail shells that are not used up after a day's work. Like gas-powered methods, it also has disadvantages such as carbon deposits and high noise.

[0005] 3) The disadvantage of air compressor power is that you need to carry a bulky air compressor while nailing. The compressor also requires a power socket. Many construction sites do not provide fixed power sockets. Even if a power supply is provided, you need to connect an air pipe to the nail gun to transmit the power source to the nail gun. You need to carry a lot of additional equipment while nailing.

[0006] In summary, the driving methods used in existing nail driving tools all have corresponding shortcomings, cannot meet the needs of different usage scenarios, have a narrow scope of application, and are not suitable for large-scale promotion and use. To this end, we propose an air-powered insulation nail driving tool to solve the above problems. Utility Model Content

Compared with the driving method in the prior art, the driving method in the present striking tool is low in cost, simple to use and safer.

[0008] In order to solve the above problems, the present invention provides the following technical solutions:

[0009] An air-powered insulation nail striking tool comprises a striking tool body, an air storage assembly arranged on the striking tool body, and a power source for pressurizing or depressurizing the air storage assembly, wherein: the air storage assembly comprises a cylinder body fixedly arranged on the striking tool body and a first piston and a second piston sealed inside the cylinder body, and the second piston can move closer to or away from the first piston to form an air storage area with adjustable size between the first piston and the second piston, the second piston is arranged at one end of the gun nozzle near the striking tool body, and a firing pin is coaxially fixed on the second piston, one end of the firing pin extends into the gun nozzle, and the power source is used to drive the firing pin to move along the length direction of the gun nozzle to pressurize or depressurize the air storage area.

[0010] As a further solution of the present invention: the power source includes a power motor fixedly arranged on the striking tool body, a wheel disc is rotatably arranged on the striking tool body, and the output shaft of the power motor is transmission-connected to the wheel disc, and the wheel disc is meshed with the firing pin, so that the rotation of the wheel disc can drive the firing pin to move along the length direction of the gun muzzle.

[0011] As a further solution of the present invention: a plurality of pins are provided in an outer circumferential array of the wheel disc, a tooth portion is provided on the striker along its length direction, and the tooth portion meshes with the wheel disc having the plurality of pins for transmission.

[0012] As a further solution of the present invention: a notch is provided on one side of the wheel disc for disengaging from the upper teeth of the striker.

[0013] As a further solution of the present invention: the power source also includes a speed change gear box fixedly arranged on the striking tool body, and the power motor and the wheel are connected through the speed change gear box.

[0014] As a further solution of the present invention: the power source also includes a battery that is detachably arranged on the striking tool body, and the battery is electrically connected to the power motor.

[0015] As a further solution of the present invention: the cylinder body is configured as a double-cylinder structure consisting of an inner cylinder body and an outer cylinder body, and the inner cylinder body is coaxially arranged inside the outer cylinder body, and the first piston and the second piston are both coaxially arranged inside the inner cylinder body.

[0016] As a further solution of the present invention: an anti-collision block is fixedly provided at the internal port of the inner cylinder body, and the anti-collision block is located between the second piston and the gun nozzle.

[0017] As a further solution of the present invention: the anti-collision block is sleeved on the outside of the striker, and one end of the anti-collision block facing the second piston is set in a smooth curve transition.

[0018] As a further solution of the present invention: the first piston and the second piston are both provided with an annular sealing ring which is sealedly connected to the inner wall of the inner cylinder.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1.

[0021] 2. Through the setting of the gas storage area, the power source is used to drive the firing pin to move along the length direction of the gun mouth, so that the gas storage area is pressurized or depressurized. When the gas pressure inside the gas storage area gradually increases to a specified level, the power source will release the restriction on the firing pin, and the pressure inside the gas storage area will be released instantly, which will drive the second piston and the firing pin toward the gun mouth, and then the firing pin can knock out the nail at the gun mouth.

[0022] 3. By opening a notch on the wheel, when the wheel drives the firing pin to move, when the notch on the wheel rotates to the tooth part of the firing pin, the wheel will release the engagement lock on the firing pin, and then under the action of the high pressure in the gas storage area, the firing pin will be quickly pushed toward the muzzle of the gun, quickly completing the nailing action.

[0023] 4. By setting the anti-collision block, the anti-collision block can block the movement of the second piston, so that the movement of the second piston will not cause impact damage to the port of the inner cylinder body, thereby extending the service life of the striking tool.

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 5 As shown, an air-powered insulation nail striking tool includes a striking tool body 1, an air storage component arranged on the striking tool body 1, and a power source for pressurizing or depressurizing the air storage component, wherein the air storage component and the power source together constitute the drive for nails in the striking tool, and the mutual cooperation between the two enables the nails at the gun nozzle 4 on the striking tool to be quickly struck into the interior of an object.

[0033] like Figure 4-Figure 5 As shown, specifically, for the arrangement of the above-mentioned gas storage assembly, the gas storage assembly includes a cylinder body fixedly arranged on the striking tool body 1 and a first piston 2 and a second piston 3 sealed inside the cylinder body. Specifically, the first piston 2 and the second piston 3 are both provided with an annular sealing ring 16 that is sealed and connected to the inner wall of the inner cylinder body 13; the second piston 3 can move closer to or away from the first piston 2 to form an adjustable gas storage area between the first piston 2 and the second piston 3, and gas is pre-stored inside the gas storage area (the gas can be air or other safety gases). The second piston 3 is arranged at one end of the gun nozzle 4 close to the striking tool body 1, and a firing pin 5 is coaxially fixed on the second piston 3, and one end of the firing pin 5 extends into the gun nozzle 4. The power source is used to drive the firing pin 5 to move along the length direction of the gun nozzle 4 to pressurize or release the gas storage area. When in use, the nail can be placed at the gun mouth 4 in advance, and then the power source can be started so that the power source drives the firing pin 5 to move. The movement of the firing pin 5 can drive the second piston 3 to move toward the first piston 2, and then the gas storage area between the first piston 2 and the second piston 3 will be compressed, and the gas pressure inside the gas storage area will increase. When compressed to a specified degree, the power source will release the restriction on the firing pin 5, and then the pressure inside the gas storage area will be released instantly, which will drive the second piston 3 and the firing pin 5 toward the gun mouth 4, and then the firing pin 5 can knock out the nail at the gun mouth 4.

[0034] like Figure 2-Figure 3 As shown, the power source arrangement described above includes a power motor 6 fixedly mounted on the striking tool body 1. A wheel disc 7 is rotatably mounted on the striking tool body 1, and the output shaft of the power motor 6 is drivingly connected to the wheel disc 7. The wheel disc 7 is meshedly connected to the striker 5, so that the rotation of the wheel disc 7 can drive the striker 5 to move along the length of the muzzle 4. Specifically, a plurality of pins 8 are arranged in a circumferential array on the outer periphery of the wheel disc 7. The striker 5 is provided with a tooth portion 9 along its length, and the tooth portion 9 meshes and drives with the wheel disc 7 having the plurality of pins 8. During operation, the power motor 6 is started, and the output shaft of the power motor 6 can drive the wheel disc 7 to rotate. Since multiple pins 8 are engaged with the teeth 9, the rotation of the wheel disc 7 can drive the striker 5 to move, thereby achieving the purpose of the second piston 3 approaching the first piston 2. That is, the air storage area will be compressed and its internal pressure will increase. After the engagement between the wheel disc 7 and the teeth 9 on the striker 5 is released, the pressure inside the air storage area will be released instantly, which will drive the second piston 3 and the striker 5 to move toward the gun nozzle 4, and then the striker 5 can knock out the nail at the gun nozzle 4.

[0035] like Figure 5 As shown, in order to automatically release the restriction of the wheel disc 7 on the firing pin 5, a notch 10 for disengaging from the tooth portion 9 on the firing pin 5 can be opened on one side of the wheel disc 7. In the process of the wheel disc 7 driving the firing pin 5 to move, when the notch 10 on the wheel disc 7 rotates to the tooth portion 9 of the firing pin 5, the wheel disc 7 will release the engagement lock on the firing pin 5, and then under the action of the high pressure in the gas storage area, the firing pin 5 will be quickly pushed toward the muzzle 4, and the nailing action will be quickly completed.

[0036] For example Figure 2-Figure 3 As shown, in order to increase the rotational torque of the wheel disc 7, the power source can be configured to further include a speed change gear box 11 fixedly mounted on the striking tool body 1, and the power motor 6 and the wheel disc 7 are connected to each other through the speed change gear box 11. Furthermore, in order to facilitate the striking tool of the present invention to adapt to any scenario, the power source can be configured to further include a battery 12 detachably mounted on the striking tool body 1, and the battery 12 is electrically connected to the power motor 6.

[0037] like Figure 4As shown, preferably, the cylinder body in the striking tool of this embodiment is configured as a double-cylinder structure consisting of an inner cylinder body 13 and an outer cylinder body 14, with the inner cylinder body 13 coaxially disposed inside the outer cylinder body 14, and the first piston 2 and the second piston 3 both coaxially disposed inside the inner cylinder body 13. A bumper block 15 is fixedly disposed at the internal port of the inner cylinder body 13, and the bumper block 15 is located between the second piston 3 and the muzzle 4. The bumper block 15 is sleeved on the outside of the firing pin 5, and the end of the bumper block 15 facing the second piston 3 is configured as a smooth curve transition. The provision of the bumper block 15 can block the movement of the second piston 3, so that the movement of the second piston 3 does not cause impact damage to the port of the inner cylinder body 13.

[0038] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
