Description

Technical Field

[0001] The utility model relates to the technical field of nail fixing devices, in particular to a noise-reducing, slag-discharging, easily disassembled and power-adjustable nail fixing device. Background Art

[0002] The nail fixer is a kind of equipment used in decoration construction. Its characteristics are that it does not require power supply, does not require climbing, can operate in a small space, does not require electric hammer drilling, has no dust pollution, and is easy to operate.

[0003] The existing nail fixing device has the following problems when adjusting the power:

[0004] (1) The force of a conventional nail fixer is adjusted by plugging the through hole with a small screw on the nail tube.

[0005] (2) Small screws usually come in hexagonal and cross types.

[0006] (3) Small screws are prone to stripping, which often makes it impossible to remove the screws and adjust the power.

[0007] (4) The tools for removing screws, such as small wrenches and screwdrivers, are also prone to slipping, which makes it impossible to remove the screws. The entire nail tube needs to be replaced, which is labor-intensive and time-consuming.

[0008] (5) Tools are required to adjust the power. Without tools, it cannot be adjusted, which increases the difficulty of adjusting the power.

[0009] (6) When working for a long time, small screws are particularly difficult to remove, and there is no way to adjust the power. The only option is to replace accessories, which increases costs.

[0010] (7) Internal hole tapping is difficult and the processing is time-consuming and labor-intensive.

[0011] The existing nail fixing device has the following problems when removing the silencer head:

[0012] (1) There is a force-bearing and positioning step at the rear end of the nail tube;

[0013] (2) When the silencer sleeve is full of residue, the nail tube is stuck and cannot be removed. The disassembly process is very difficult or even impossible to complete. The consequence is that when the nail fixer is disassembled for maintenance after a period of use, the nail tube cannot be removed and the entire front-end assembly has to be discarded, resulting in a waste of resources.

[0014] (3) The nail tubes are all threaded and can easily get stuck and cannot be removed. The silencer sleeve is also integral and is difficult to remove after a long time.

[0015] The existing nail fixing device has the following problems during maintenance and disassembly:

[0016] (1) The existing nail fixing device mainly consists of a main sleeve, a firing pin sleeve, a firing pin, a nail tube, a movable sleeve, a return spring, etc., but the spring is often stuck, making it inconvenient to disassemble.

[0017] (2) The existing nail gun has a short firing pin, a poor firing rate, many duds, and is incompatible.

[0018] (3) The existing nail fixing device has a spring base under the firing spring, which makes it difficult to discharge dust and residue. When a large number of nails are driven, it is easy to get blocked, resulting in failure to fire and difficulty in disassembly. In addition, an additional part is added, which increases weight and cost.

[0019] (4) When the existing nail fixer is maintained, the protective cover is often easily covered with dust, causing it to get stuck and unable to be removed. It can only be cut open with a cutting machine or other tools, and the limit pin inside is also difficult to remove. There is no way to disassemble it for cleaning and maintenance, resulting in it being unusable and having to be thrown away.

[0020] (5) When disassembling the existing nail fixing device, the internal components can only be removed by removing the limit pin inside the protective cover. This is too restrictive.

[0021] (6) The firing pin sleeve of the existing nail gun has 3 grooves, and the main sleeve also has 2-3 grooves or more. When it is first used, the firing pin sleeve is often installed upside down, and it is installed on the back, which makes it impossible to fire normally, increasing after-sales problems. Utility Model Content

[0022] The utility model aims to make up for the deficiencies of the prior art and provides a noise-reducing, slag-discharging, easily disassembled, power-adjustable nail fixing device.

[0023] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0024] A silent, slag-removing, easily disassembled, and power-adjustable nail fixing device comprises a launching tube assembly, wherein the launching tube assembly comprises a threaded launching tube, a first thread is provided on the top of the threaded launching tube, a first boss is provided behind the first thread, a second thread is provided behind the first boss, and a second boss is provided behind the second thread, wherein the first thread is in opposite directions to the second thread, a silencer hole is provided below the second boss of the threaded launching tube, a third thread is provided behind the silencer hole of the threaded launching tube, a plurality of special nail pressure relief holes are provided on the third thread, and at least one nut sleeve is provided on the outer side of the pressure relief hole of the threaded launching tube; the threaded launching tube is connected to an orthodontic sleeve cover through a second thread, the orthodontic sleeve cover is connected to a limited position silencer sleeve, the rear end of the limited position silencer sleeve can be movably inserted into the limited sleeve, a shell extraction sleeve is provided on the orthodontic sleeve cover, and the top end of the threaded launching tube is connected to an anti-thread steel cover through a first thread.

[0025] Further, the various special nails include nails with lengths of 32mm, 42mm, 47mm, 52mm and 57mm.

[0026] Furthermore, the nut sleeve is provided with one or more through holes, and the nut sleeve is circular or polygonal.

[0027] Furthermore, it also includes a firing pin seat assembly, a limiting body and a firing tail body, the firing pin seat assembly includes a shell ejection spring, a firing pin seat, a firing pin, a firing pin pin, a safety pin, a safety pin spring, a firing pin body, a firing spring and a firing pin seat spring, a limiting step is provided in the middle part of the limiting body, the limiting sleeve is connected to the limiting body, the limiting body is arranged outside the firing pin seat, the protective sleeve is arranged outside the limiting body, and the limiting body is connected to the firing tail body through a thread.

[0028] Furthermore, the firing pin, the firing pin body, the firing pin pin, the safety pin spring and the safety pin are housed in the firing pin seat.

[0029] Furthermore, a limit pin hole, a safety pin countersunk hole and a firing pin pin through hole are opened on the firing pin body. The firing pin is installed in the through hole at the top end of the firing pin body and connected through the firing pin pin. The safety pin spring and the safety pin are installed in the safety pin countersunk hole.

[0030] Furthermore, a firing pin hole is provided in the firing pin seat, and a firing pin seat is provided on the outer cover of the firing pin.

[0031] Furthermore, a firing unlocking inclined plane is provided on the top of the firing tail body, a protective cover is installed outside the limiting body, and the lower end of the limiting body is threadedly connected to the firing tail body.

[0032] Compared with the prior art, the mute slag removal easy-to-detach power-adjustable nail fixing device has the following beneficial effects:

[0033] 1. In the present invention, the limit pin can slide along the inside of the limit body to achieve the function of fixing the moving direction of the firing pin seat assembly. The safety pin fixes the relative position of the firing pin body and the firing pin seat in the locked state. When the safety pin is squeezed by the inclined surface and enters the safety pin countersunk hole, the safety pin is unlocked, and the rebound force of the firing spring on the firing pin body is no longer restricted. The firing pin body and the firing pin are quickly ejected to achieve firing. After the limit pin hits the limit step of the limit body, the limit step plays the role of a limit pin. The limit pin receives the free elastic force of the upper and lower springs, and the safety pin naturally returns to the safety pin hole to achieve a free lock pin.

[0034] 2. The threaded launch tube of the utility model is provided with a special power adjustment hole suitable for 32 / 42 / 47 / 52 / 57 nails. A nut sleeve is provided on the threaded launch tube, and the power can be adjusted by rotating the nut sleeve to block the hole. When the nut sleeve blocks the pressure relief hole, the power of the nail is increased; when the nut sleeve blocks the pressure relief hole, the power of the nail is increased; when the nut sleeve blocks the pressure relief hole, the power of the nail is increased. And so on. The nut sleeve can be used alone or in combination. When two or more nut sleeves are used in combination, the upper and lower nuts can be tightened and positioned with each other. When positioned at the pressure relief hole, stepless gear shifting can be achieved to adjust the power. Compared with the launch tube with screws in the prior art, it is necessary to tap the threads one by one, which is complicated, labor-intensive and time-consuming. It also saves the tedious work of unscrewing the screws, saves more than times of working hours, improves work convenience, and significantly enhances practicality and flexibility compared to the nail fixer in the prior art.

[0035] 3. The safety pin of the utility model is a curved surface or a beveled edge, and is limited by the safety pin hole on the firing pin seat, which solves the problem of limiting by the step on the brake pin in the prior art; the utility model makes processing simpler and more convenient. It saves processing costs and significantly improves processing efficiency. It solves the problem that the brake pin without step limiting in the prior art is easy to fall out and be lost during disassembly and maintenance. The safety pin of the utility model will not fall out during disassembly and maintenance, which greatly reduces the problem of lost accessories and saves material costs and labor costs.

[0036] 4. The position-limiting silencer sleeve of the utility model has no threaded connection with the threaded transmitting tube. The boss presses the positive tooth cover tightly, and the negative tooth steel cover makes the boss and the positive tooth cover fit more tightly, so that the silencer effect is better. The problem that the nail tube and the silencer sleeve in the prior art are easy to loosen during use, resulting in loud noise. And the dust cover and the heat insulation cover must be disassembled before the silencer sleeve can be tightened again. The steps are very cumbersome. After use, the temperature of the silencer sleeve is very high and it is very easy to get hot. The utility model cleverly uses the positive and negative tooth structure. You only need to tighten the transmitting steel cover to seal and silence. There is no need to disassemble the heat insulation cover and other cumbersome steps. It is not hot to the touch, which facilitates the operation and improves the safety of the utility model.

[0037] 5. A gap is provided between the bottom of the position-limiting silencer sleeve and the bottom of the threaded launch tube of the utility model. The power generated after the nail is fired will squeeze the plastic shell residue inside the silencer sleeve and crush the plastic shell residue into powder. Automatic slag discharge, exhaust and heat dissipation can be achieved through the gap between the position-limiting silencer sleeve and the bottom of the threaded launch tube. The slag discharge effect is more significant than the granular slag discharge effect in the prior art. It can effectively prevent ash and slag from accumulating in the nail fixer, and quickly dissipate heat to avoid damage to components due to excessive temperature. It can prevent the threaded launch tube and other components from overheating after firing and protect the threaded launch tube. It overcomes the problem that the ash and slag cannot be discharged after the existing nail fixer is fired and the operator cannot hold it due to excessive heat. It facilitates operation and improves the safety of the utility model.

[0038] 6. The guide stroke of the firing pin seat of the utility model is lengthened, so that the release force of the firing spring is greater, and thus the firing force is greater. The firing pin is lengthened and thickened, and the firing pin head protrudes longer from the top of the firing pin seat when firing, so that the firing rate is higher. The nail fixer can not only use ordinary one-piece bullets, but also one-piece bullets made of other materials such as nitrocellulose, double-base propellant, single-base propellant, and multi-base propellant one-piece bullets. It is suitable for the one-piece bullets currently circulating on the market. After research and testing and practical experience summary, it can be stably fired, which increases the scope of application and has more usage scenarios.

[0039] 7. The firing pin body of the utility model can cooperate with the inclined surface on the firing tail body to limit the compression distance between the firing pin seat spring and the firing spring, effectively avoiding the firing pin seat spring and the firing spring being compressed to the limit distance each time during use, thereby preventing the firing pin seat spring and the firing spring from being easily damaged and having a short life. In actual use, the life span can reach more than times that of the existing spring.

[0040] 8. When disassembling and cleaning the utility model, do not disassemble the front end, directly disassemble the firing tail body at the back, and disassemble it in one step. And the firing pin seat inside does not need to be installed in the right direction. It solves the problem that the firing pin sleeve of the nail fixing device in the prior art is easy to be installed upside down and installed on the back. After using it for a period of time, the protective cover and the limit pin cannot be removed. Provide a silent, slag-discharging, easy-to-disassemble and power-adjusting nail fixing device.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] See also Figure 1 to Figure 3 As shown, the utility model provides a technical solution: a mute slag removal easy-to-detach power-adjusting nail fixing device is mainly divided into two parts: a power-adjusting mechanism and a firing mechanism:

[0047] The power adjustment mechanism is composed of a reverse-thread steel cover 1, a threaded launching tube 5, a positive-thread sleeve cover 3, a limit silencer sleeve 4, a limit sleeve 7 and a shell extraction sleeve 2.

[0048] The top of the threaded launch tube 5 is provided with a first thread 51, and behind the first thread 51 there is a first boss 53, and the first boss 53 is provided with a second thread 52, and behind the second thread 52 there is a second boss 54, wherein the first thread 51 and the second thread 52 have opposite screwing directions, and two circles of silencer holes C1 and C2 are provided below the second boss 54 of the threaded launch tube 5, and the threaded launch tube 5 is provided with a third thread 55 and various nail exhaust holes (pressure relief holes) such as D1, D2, and D3, and the power is adjusted by rotating the nut sleeve 6 to block the holes. When the nut sleeve 6 blocks the 32 nail pressure relief hole D1, the power of the 32 nails is increased; when the nut sleeve 6 blocks the 42 nail pressure relief hole D2, the power of the 42 nails is increased; when the nut sleeve 6 blocks the 47 nail pressure relief hole D3, the power of the 47 nails is increased. And so on.

[0049] In this embodiment, three nut sleeves 6 are used in combination. In other embodiments, when two or more nut sleeves 6 are used in combination, the upper and lower nuts can be tightly fixed to each other. When positioned at the pressure relief hole, stepless gear shifting can be achieved to adjust the required power (launch force).

[0050] The firing mechanism is composed of a firing pin seat assembly, a limiting body 17, a protective cover 16 and a firing tail body 20:

[0051] The firing pin seat assembly is composed of an ejector spring 8, a firing pin seat 9, a firing pin 10, a firing pin pin 11, a safety pin 12, a safety pin spring 13, a firing pin body 14, a limit pin 15, a firing spring 19, and a firing pin seat spring 18. The structure of the firing pin seat assembly has been described in detail in previous patent applications and will not be repeated here.

[0052] The assembly steps of each component of the utility model are as follows:

[0053] (1) Adjusting the power mechanism: first, install the limit silencer sleeve 4 into the limit sleeve 7, then screw the positive threaded sleeve cover 3 onto the threaded launch tube 5, and then connect the limit silencer sleeve 4 together, and then screw the shell extraction sleeve 2 onto the positive threaded sleeve cover 3 (connected by the second thread 52), and then screw the negative threaded steel cover 1 onto the threaded launch tube 5 (connected by the second thread 51).

[0054] (2) Firing pin seat assembly: First, install the safety pin spring 13 and the safety pin 12 into the safety pin countersunk hole of the firing pin body 14, then install the firing pin 10 into the upper end of the firing pin body 14, insert the firing pin pin 11, and install them into the firing pin seat 9 together, and the safety pin 12 is locked in the safety pin hole on the firing pin seat 9. The limit pin 15 passes through the holes of the firing pin seat 9 and the firing pin body 14, then install the ejector spring 8 at the front end of the firing pin seat 9, and install the firing spring 19 and the firing pin seat spring 18 at the rear end of the firing pin seat 9.

[0055] (3) Insert the firing pin seat assembly from the rear end of the limiting body 17 in one step, install the protective cover 16, and then connect the firing tail body 20 through threads, and compress the firing spring 19 and the firing pin seat spring 18 at the same time. Then connect the power adjustment mechanism to the limiting body 17 through threads. The assembly is completed.

[0056] The firing pin seat 9 of the utility model is provided with a safety pin hole, a limit pin 15 and a movable groove of the safety pin 12 are provided on it, and a movable groove of the limit pin 15 is provided on the opposite side. The limit pin 15 passes through the limit pin hole of the firing pin body 14, is inserted into the movable groove of the firing pin seat 9, and slides in a directional manner. The firing mechanism is composed of a firing pin seat assembly, a limit body 17 and a firing tail body 20, and the role of the firing tail body 20 is to unlock and connect the fixed limit body 17. When the nail holder is in a free state, the firing pin seat 9 slides forward to the lowest point along the firing pin seat 9 under the action of the firing pin seat spring 18; when the nail holder fires, the firing pin seat 9 is pushed backward to the unlocking inclined surface of the firing tail body 20 under the action of the backward thrust of the integrated nail, and the safety pin 12 generates a downward force under the action of the unlocking inclined surface of the firing tail body 20, and the safety pin 12 and the safety pin spring 13 are compressed, so that the firing pin body 14 is released, and the firing pin body 14 instantly generates a forward thrust under the action of the compression force of the firing spring 19, and the tip of the firing pin violently pierces into the integrated bullet. The integrated bullet explodes and releases huge heat, which is converted into mechanical energy under the action of the threaded launch tube 5, and the integrated nail is hit into the base. The firing pin seat spring 18 is also depressurized at the same time. As the elastic force of the firing pin seat spring 18 is released, the firing pin seat 9 moves along the limiting body 17, and the safety pin 12 returns to the safety pin hole, realizing a natural locking pin.
