Description

Technical Field

[0001] The utility model belongs to the technical field of hardware installation of door and window profiles, and particularly relates to a pin gun head. Background Art

[0002] Pin guns are used to drive pins into door and window profiles to position hardware structures. The existing pin gun head generally includes a raised pin driving portion for directly applying driving force to the pin. Since the pin gun head directly applies force to the pin, it is easy to wear, and it is not easy to tighten the pin in one driving action. Multiple driving actions are likely to damage the hardware structure, which is very inconvenient to use. Utility Model Content

[0007] Furthermore, the straight line where the center of the pre-punched hole and the center of the locking column are located is on the same straight line as the central axis in the length direction of the end surface of the flat area.

[0008] Furthermore, the locking column is provided with an external thread, the end surface of the flat area is provided with a locking hole, the locking hole is provided with an internal thread, and the locking column is detachably connected to the locking hole through a threaded structure.

[0009] Furthermore, the depth distance between the bottom surface of the pre-punched hole and the end surface of the flat area is greater than the length distance of the locking column extending from the end surface of the flat area.

[0010] Furthermore, the shape of the locking column and the shape of the nut hole are both circular, and the circular size of the locking column is consistent with the circular size of the nut hole.

[0011] Furthermore, the shape of the pre-punched hole is circular, which is consistent with the shape of the outer edge of the nut, and the circular size of the pre-punched hole is consistent with the size of the outer edge of the nut.

[0012] The beneficial effects of the utility model are:

[0013] The pin gun head of this solution pre-punches the pin into the structural part by pre-drilling, and then locks the pin by inserting the locking column into the nut hole of the pin.

[0020] See also Figure 1-2 The utility model discloses a pin gun head, which is used for driving and locking a pin. The pin includes a nut and a screw. A nut hole is provided at the center of the nut. The pin gun head includes a gun head body 10 and a locking column 20. The pin driving end of the gun head body 10 is provided with a pre-punched hole 1232 for positioning the outer edge of the nut of the pin. After the nut for the pin is inserted into the pre-punched hole 1232, the gun head body 10 applies a force to the pin to drive the pin into the structural member. The locking column 20 is detachably connected to the gun head body 10, and is used to be inserted into the nut hole to lock the pin after the pin is driven into the structural member.

[0021] The pin gun head of the present invention pre-punches the pin into the structural part by pre-punching the hole 1232, and then locks the pin by inserting the locking column 20 into the nut hole of the pin. The two-step operation can ensure that the pin is tightened into the structural part without damaging the structural part. At the same time, since the locking column 20 is detachably connected to the gun head body 10, the locking column 20 can be replaced in time after it is worn, without replacing the pin gun head, saving costs and processes.

[0022] In this embodiment, the gun head body 10 includes a mounting portion 11 and a gun head 12, the mounting portion 11 is used to connect the gun head 12, and the locking column 20 and the pre-punched hole 1232 are both provided on the gun head 12. It can be understood that the gun head body 10 needs to be installed on a pinning tool, one end of the mounting portion 11 is connected to the gun head 12, and the other end is installed on the pinning tool.

[0023] In this embodiment, the gun head 12 includes a cylindrical area 121, a transition area 122 and a flat area 123. The cylindrical area 121 is used to connect to the mounting portion 11. The thickness of the flat area 123 is less than that of the cylindrical area 121. The transition area 122 is arranged between the cylindrical area 121 and the flat area 123. The pre-punched hole 1232 and the locking column 20 are both arranged on the end surface 1231 of the flat area 123. The space of the flat area 123 is smaller than that of the cylindrical area 121. The arrangement of the flat area 123 is conducive to extending into the structural member and convenient operation.

[0024] In this embodiment, the straight line where the center of the pre-drilled hole 1232 and the center of the locking column 20 are located is on the same straight line as the longitudinal center axis of the end surface 1231 of the flat area 123. Placing the pre-drilled hole 1232 and the locking column 20 on the center axis can make the driving operation more uniform and stable.

[0025] In this embodiment, the locking column 20 is provided with an external thread, the end surface 1231 of the flat area 123 is provided with a locking hole 1233, the locking hole 1233 is provided with an internal thread, and the locking column 20 is detachably connected to the locking hole 1233 through the thread structure. It should be noted that the locking column 20 itself is a very small structure, as long as it can be detachably connected to the locking hole 1233, the specific locking method is not limited.

[0026] In this embodiment, the depth distance between the bottom surface of the pre-punched hole 1232 and the end surface 1231 of the flat region 123 is greater than the length distance of the locking column 20 extending from the end surface 1231 of the flat region 123 .

[0027] In this embodiment, the shape of the locking column 20 and the shape of the nut hole are both circular, and the circular size of the locking column 20 is consistent with the circular size of the nut hole. The shape of the pre-punched hole 1232 and the shape of the outer edge of the nut are both circular, and the circular size of the pre-punched hole 1232 is consistent with the size of the outer edge of the nut. Of course, when the shape of the outer edge of the nut and the nut hole changes, the shapes of the locking column 20 and the pre-punched hole 1232 can also be adaptively changed to ensure that they match each other.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
