Description

C type electric nail gun

This work is about electric nail guns, especially about the assembly structure of C-type electric nail guns.

An electric tool, such as an electric nail gun, is a tool that uses an electric motor to output kinetic energy to the outside. It has the advantages of being convenient to use and has no restrictions on the use environment.

The nail gun is a tool used in construction and decoration. The nail gun is used to fire nails to connect different workpieces together. Conventional nail guns, such as Taiwan Patent Publication No. I603818 "Nail Cassette Assembly and Nail Gun Containing the Nail Cassette Assembly", disclose a nail casket assembly and a nail gun comprising the nail casket assembly.

As for the construction of wire materials such as spring beds, light steel frames, etc., a C-type electric nail gun will be used to complete the binding of different wire-shaped materials. The known C-type electric nail gun is shown in the "Nail Clip Driving Device of Electric C-type Nail Gun" in Taiwan Announcement No. M591028.

In the commonly used electric nail gun, the mandrel of the push rod is provided with external threads, while the end surface of the drive shaft (screw) has a mandrel hole and internal threads corresponding to the external threads, so that the mandrel can be screwed to the center. Shaft hole for fixing the pusher rod.

However, due to the locking and combining method of the screw pusher, the outer thread of the mandrel is exposed, so when the mandrel is screwed into the mandrel hole, the external dirt will be brought in and accumulated in the electric nail gun. Internally, when the electric nail gun is used for continuous nail output, the existence of dirt will cause the mechanism to get stuck, which will easily cause damage to the internal parts of the electric nail gun.

The main purpose of this creation is to disclose a structure of an electric nail gun to prevent external dirt from entering the interior of the electric nail gun.

In order to achieve the above purpose, this creation provides a C-type electric nail gun, which includes a fixed seat, a coupling, a push screw rod and two jaws, wherein the fixed seat has a first fixed part, a second fixed part part, an accommodating space and a cover, the accommodating space is located between the first fixing part and the second fixing part, and the cover covers the accommodating space. The coupling is pivotally connected to the first fixing part and has a screw rod extending into the accommodating space, and the screw rod has an external thread. The pusher rod has a pusher piece and a mandrel, the mandrel is connected with the pusher piece, and the mandrel passes through the second fixing part and extends into the accommodating space, and the mandrel has a matching lock In the inner screw hole of the outer thread, the two jaws clamp the push screw rod up and down to form a nail outlet.

Accordingly, since the mandrel is locked with the outer thread of the screw rod through the inner screw hole after it is inserted into the accommodating space, there is no exposed thread, so external dirt will not pass through the exposed thread. The screw teeth brought into the C-type electric nail gun will not cause damage to the internal parts of the C-type electric nail gun, such as the coupling, which can increase the service life and meet the needs of use.

Regarding the detailed description and technical content of this creation, the accompanying diagrams are now explained as follows:

Please refer to Fig. 1 and Fig. 2, which are the structure decomposition and partial side view of this creation, as shown in the figure: this creation provides a C-type electric nail gun, and the C-type electric nail gun includes a fixing seat 20 and a shaft coupling device 30, a nail pusher rod 40 and two jaws 50, wherein the fixing seat 20 has a first fixing part 21, a second fixing part 22, an accommodating space 23 and a shell 24, the accommodating space 23 Located between the first fixing portion 21 and the second fixing portion 22 , the housing 24 covers the accommodating space 23 .

The coupling 30 is pivotally connected to the first fixing portion 21 and has a screw rod 31 extending into the accommodating space 23 , and the screw rod 31 has an external thread 311 .

The push rod 40 has a push piece 41 and a mandrel 42, the mandrel 42 is connected to the push piece 41, and the mandrel 42 passes through the second fixing part 22 and extends into the accommodating space 23, and The mandrel 42 has an inner threaded hole 421 matching and locking the outer thread 311 . The two jaws 50 clamp the pusher rod 40 up and down to form a nail outlet 51 .

Furthermore, a partition 60 can be set in the accommodating space 23, the partition 60 has a perforation 61, the perforation 61 is slightly larger than the screw rod 31, the screw rod 31 passes through the perforation 61, and the perforation 61 can further block dirt. The effect of dirt and dust.

In addition, in order to fix the relative position between the screw rod 31 and the inner screw hole 421 , the screw rod 31 can lock a limiting plate 312 , and the limiting plate 312 resists the mandrel 42 . Moreover, a bearing 70 is disposed between the spindle 42 and the second fixing portion 22 to reduce friction and increase stability during rotation.

To sum up, compared with conventional knowledge, the characteristics of this creation include at least:

1. By allowing the mandrel to have the design of the inner screw hole, and after the mandrel is inserted into the accommodating space, it is locked with the outer thread of the screw through the inner screw hole, without external appearance The screw teeth, so the external dirt will not be brought into the fixed seat through the exposed screw teeth, that is to say, there is no external dirt that will cause the mechanical parts of the C-type electric nail gun, such as the coupling and other parts The damage problem can increase the life of the C-type electric nail gun and meet the needs of the C-type electric nail gun in use.

2. Through the additional partition installed in the accommodation space, a barrier space can be formed to prevent external dust and dirt from passing through the accommodation space

Therefore, this creation is very progressive and meets the requirements for applying for a patent. I would like to file an application in accordance with the law, and pray that the bureau will grant the patent as soon as possible. I really appreciate it.
