Description

Glue gun holder

The invention relates to a glue gun seat.

The general glue gun is used to fill the gap between the wall with glue or the gap between the two objects. Its structure includes a seat, a push rod that is movably arranged on the seat, and a driving member that can drive the push rod. And a pressure handle that can push against the driving part. When in use, press the pressure handle to drive the push rod to push the rubber barrel forward to control the glue discharge.

Conventional glue guns, such as Taiwan Patent No. I276473 "Improvement Structure for Glue Gun Empty Stroke", have pipe grooves to support the glue cartridges. However, the pipe grooves are located under the glue gun as a whole, causing the weight of the glue cartridges to concentrate on the bottom , and when the rubber tube deflects due to being pressed by the push rod, the rubber tube obliquely presses against the pipe groove, and the pipe groove is easily deformed, warped or twisted by force, and the supporting effect is not good.

Therefore, it is necessary to provide a novel and progressive glue gun holder to solve the above-mentioned problems.

The main purpose of the present invention is to provide a glue gun mount that can stably support a glue cartridge and is not easily deformed, warped or twisted by force.

To achieve the above object, the present invention provides a glue gun seat, comprising: a seat, which includes a front end, a rear end, two arc-shaped side walls and an accommodating space, the front end and the rear end along a center The axes are arranged at intervals, the central axis extends along an axial direction, the two arc-shaped side walls are respectively arranged at intervals and connected between the front end and the rear end, the front end, the rear end, and the two arc-shaped side walls constitute In the accommodating space, the seat body defines a base reference line and a central reference plane, the base reference line passes through one of the bottom ends of each of the arc-shaped side walls, the central reference plane is parallel to the base reference line, and radially passes through the two The arc-shaped side walls intersect with the central axis transversely, the central datum plane is used to define an upper side and a lower side on opposite sides of each arc-shaped side wall, and a top end surface of the upper side is between the central datum plane A first distance is defined, the rear end defines a reference line extending radially, perpendicular to the central datum plane and transversely intersecting the central axis, the rear end has a ring wall surrounding the center The axis extends, and the ring wall defines a radial distance which is 2.5 times to 15 times the first distance.

The following examples illustrate the possible implementation of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" before the nouns mentioned in the text do not limit the number. It can also be "plural" according to the needs, and the change in the number is also within the scope of protection, which will be described first.

The size allows the rubber cartridge 4 to pass through and the diameter of the bottom opening 16 does not allow the glue cartridge 4 to pass through and is light in weight. In this embodiment, the height dimension ranges from 52.00 mm to 55.00 mm, preferably from 53.00 mm to 54.00 mm.

The top end surfaces 134 of the upper side portions 132 of the two arc-shaped side walls 13 are flush with each other in the radial direction, so that the top opening 15 can be opened directly upward, which is beneficial for disassembling and installing the rubber cartridge 4 . Furthermore, the two arc-shaped side walls 13 have the same size, so that the center of gravity is centered.

The glue gun base further includes two welding pieces, each of which is welded between the rear end portion 12 and one of the arc-shaped side walls 13 , so that the rear end portion 12 and the two arc-shaped side walls 13 are connected and positioned.

In this embodiment, each of the arc-shaped side walls 13 is concavely deformed from the outside to the inside to form each of the first protrusions 17; each of the first protrusions 17 is partially deformed from the outside to the inside to form each of the second protrusions 18. Therefore, multi-stage local deformation can make the second convex portion 18 closer to the central axis A, with high structural strength, so that the two arc-shaped side walls 13 are not easily deformed, and each of the second convex portions 18 can be radially pressed. The rubber cartridge 4 located in the accommodating space 14 enables the rubber cartridge 4 (as shown in Figure 3 and Figure 4 ) or the rubber cartridge 4' (as shown in Figure 7 and Figure 8 ) of different sizes to be stably positioned in the accommodation space. Set in the space 14 without loosening. Each of the second protrusions 18 can extend around the central axis A, or extend along the axial direction.
