Description

Nail gun structure

The present invention relates to a rivet gun structure, in particular, a rivet gun structure that reduces the pressing stroke and simultaneously eliminates the invalid pressing stroke.

According to the rivet gun, it is widely used in various assembly processes to pull out the rivet to assemble the workpiece together. For example, when assembling the computer case, the rivet gun is used to pull the rivet to fix the magnetic frame or the like in the chassis. The rivet gun is a special tool for fixing the rivet on one side. After the rivet is clamped, the rivet is placed in the corresponding perforation of the conjugate, and then the tail of the ejector is pulled by the rivet gun, so that the rivet gun is used. The pull end of the insert can be deformed by force to achieve the purpose of riveting the joint, and the end of the pull nail is pulled by the pull gun, and the force is applied until the tail end is broken.

Please refer to the first figure and the second figure, which is a creation of a conventional rivet gun, which comprises a gun seat 1, a pull clamp inner rod 2 and a pressure rod 3, and the pull rod inner rod 2 The handle is disposed inside the gun seat 1 , and a handle 11 is extended at one end of the gun base 1 . The press rod 3 is pivotally disposed on the gun base 1 and presents a corresponding pressing type with the grip 11 . One end has two guiding pieces 31 extending on both sides of the inner rod 2 of the pulling clamp and interlocking therewith; thus, the pressing rod 3 is pressed, and the rod 2 is displaced through the guiding piece 31 to perform the pulling operation.

However, the guide rivet gun of the conventional rivet gun is designed to be curved in shape on both sides of the pressing piece. When the pressing rod and the handle are at the maximum opening distance, the diagonal part of the guiding piece and the inner part of the pulling piece are transmitted through the guiding piece. Card, The design of the arc-shaped pattern causes the opening distance between the pressure bar and the handle to be too long, which is disadvantageous for the user to operate with one hand, and also has the disadvantage of having an invalid pressing stroke.

In view of this, the creator has been engaged in the development of related industries for many years, in-depth discussion on the problems faced by the existing rivet guns, and actively seeks solutions. After long-term research and development, he has finally succeeded in creating A rivet gun structure is a rivet gun structure that reduces the pressing stroke and synchronously eliminates the invalid pressing stroke.

The present invention relates to a rivet gun structure, which is a rivet gun structure that reduces the pressing stroke and simultaneously eliminates the invalid pressing stroke.

In order to achieve the foregoing creative purpose, the rivet gun structure comprises a gun seat, a pull-in inner rod and a pressing rod, and the gun base has a protruding gun section formed at one end thereof, and the gun base is formed with a pull-up. The inner rod of the clamp slides the inner cavity of the clamp, and the inner cavity extends to the inner surface of the barrel section, and the gun section is provided with an adjustment head for forcing into the inner cavity, and the inner rod of the clamp is There is a telescopic chuck which is adapted to the size of the puller after being pressed by the adjusting head, and which is pulled after the displacement. The end of the gun base is extended with a handle, and the pressing rod is pivoted on the gun seat, and The handle is formed as a corresponding pressing type, and the gun seat is pivotally provided with a return spring for normally extending the handle and the pressing rod; the inner side of the inner rod of the pulling clip is formed with an inner constricting surface, and the end of the pressing rod The utility model has two guiding pieces extending on two sides of the inner rod of the pulling clip and interlocking therewith, and the connecting portion of the guiding piece and the pressing rod has a neck portion which is retracted on both sides, and the two sides of the guiding piece are respectively one The arc segment and a reinforcing segment, the curvature of the arc segment is greater than the reinforcing segment, when the grip and the pressing bar are the most When the open type, with the guide piece based reinforcement section through the cervical clamp and pull the inner rod engaging, when the lever handle is relatively compressed, the guide The film system pulls the inner rod of the pull clip through the curved section.

The aforementioned grip lock has a plurality of adjustment heads of different specifications.

As can be seen from the above-mentioned creations, the creation of the "nail gun structure" relative to the conventional rivet gun, the creation has a reinforcing section that shortens the maximum opening distance of the pressing rod and the grip, so that the operator can easily operate with one hand Pressing to carry out the nailing operation and reducing the occurrence of the invalid pressing stroke, the novel can be said to be a kind of practical and progressive creation, which is quite worthy of promotion by the industry and publicized to the public.

This creation is about a rivet gun structure, which is a rivet gun structure that reduces the pressing stroke and simultaneously eliminates the invalid pressing stroke. Please refer to the third to sixth figures, the creation of the "nail gun structure" The utility model comprises a gun base 4, a pull-in inner rod 5 and a pressing rod 6; the gun base 4 is formed with a protruding gun section 41 at one end thereof, and the gun base 4 is formed with a sliding rod inner rod 5 for sliding The inner cavity 42 is disposed to extend to the inner surface of the barrel section 41, and the barrel section 41 is selectively locked to the end surface of the adjustment head 43 for forcing into the inner cavity 42. The utility model is provided with an adjustable head 43 to adjust the corresponding puller size after being pressed, and is displaced The telescopic chuck 51 of the rear pull rivet (this creation only briefly describes the purpose and action function of the telescopic chuck 51, which is controlled by the adjustment head 43 to control the size of the opening and its elastic expansion and clamping, and the like. In the category, the first end of the gun base 4 is extended with a handle 44, which is pivotally disposed on the gun base 4 and presents a corresponding pressing type with the grip 44. A return spring 45 is provided for the handle 44 and the pressing rod 5 to be normally opened; the inner side of the rod inner rod 5 is formed with an inner constricting surface 52, and the end of the pressing rod 6 has two extensions The guiding piece 61 is connected to the two sides of the inner rod 5, and the connecting portion of the guiding piece 61 and the pressing rod 6 has a neck portion 611 which is retracted on both sides, and the two sides of the guiding piece 61 are respectively an arc. The curved section 612 and the reinforcing section 613 are curved more than the reinforcing section 613. When the handle 44 and the pressing rod 6 are in the maximum open state, the guiding piece 61 is transmitted through the neck section 611 and is reinforced. The segment 613 is latched with the inner rod 5 of the pull clamp (as shown in the fifth figure). When the pressure rod 6 is compressed relative to the grip 44, the guide piece 61 is passed through the curved section 612 to pull the inner rod 5 of the pull clamp (eg Six shown).

Further, the handle 44 is locked with a plurality of adjustment heads 43 of different specifications, and the adjustment head 43 can be locked into the inner surface of the barrel section 41 to have different lengths, so as to control the length of the telescopic chuck 51. The control of the size of the jaws is achieved, and the rivets of different specifications can be correspondingly.

It can be seen from the above-mentioned creation content that the creation of the "lace gun structure" relative to the conventional rivet gun has a reinforcing section 613 which shortens the maximum opening distance between the pressing rod 6 and the grip 44, which is convenient for the operator. The one-handed pressing is used for the rivet work. In addition, while the pressing stroke is shortened, the starting position of the inner rod 5 of the pull-tab is different from the conventional creation, and the distance between the inner rod 5 and the adjusting head 43 is relatively The creation is far away, so that when the same size adjustment head 43 is used, the degree of compression of the telescopic chuck 51 is relatively light, which in turn affects the narrowness of the jaws thereof, so as to simultaneously insert the pin into the jaw. The gap achieves the effect of reducing the invalid pressing stroke.

The above list is only for explaining the preferred embodiment of the novel creation, and it is not intended to impose any form restrictions on the creation, so that all the creations in the same creative spirit are related to the creation of the novel. Any modification or change, which is otherwise achievable and has the same effect, should still be included in the scope of this new creative intent.

In summary, the "nail gun structure" of this new type of creation is indeed practical in terms of structural design and practical use, and the disclosed structure creation is also an unprecedented innovative structure, so it has "newness" Sexuality should be undoubtedly considered, and this new creation can be more effective than the conventional structure, so it is also "progressive", which fully complies with the provisions of the new patent application of the Chinese Patent Law. Patent application, I hope that the bureau can grant the patent right in this case as soon as possible.
