Description

Technical Field

[0001] This utility model belongs to the field of glue guns, and specifically relates to a manual glue gun with adjustable glue dispensing volume. Background Technology

[0002] Manual caulking guns dispense glue by pressing a handle and are widely used in industries such as construction and decoration, electronics, automobiles, and auto parts. Existing manual caulking guns use a rotating handle to expel glue from a reservoir. The amount of glue dispensed depends on the stroke of the handle. However, the stroke of the handle in existing manual caulking guns is often fixed, so the amount of glue dispensed per press is also constant. This is not suitable for applications with varying glue dispensing requirements. Utility Model Content

[0003] The purpose of this invention is to provide a glue gun handle and glue gun, which solves the technical problem of adjustable glue output of the glue gun.

[0004] The glue gun handle includes a handle body, a handle tip, and a variable stroke mechanism. The handle tip is rotatably connected to the handle body via the variable stroke mechanism, and the rotational stroke of the handle tip relative to the handle body is variable.

[0005] The variable stroke mechanism includes a rotating block rotatably connected to the handle body. The handle is rotatably connected to the handle body via a rotating shaft. The rotating shaft is movable relative to the handle body. There are at least two rotating shafts. When one rotating shaft moves along the handle body, the handle rotates along the other rotating shafts, and the rotating block is confined to the other rotating shafts.

[0006] The rotating shaft includes a first rotating shaft and a second rotating shaft. The rotating block is provided with a first locking position and a second locking position. When the handle rotates along the first rotating shaft, the first locking position is engaged with the first rotating shaft, and the handle drives the second rotating shaft to move along the handle body. When the handle rotates along the second rotating shaft, the second locking position is engaged with the second rotating shaft, and the handle drives the first rotating shaft to move along the handle body.

[0007] One end of the handle extends into the handle body, the rotating block is built into the handle body, and one end of the handle is provided with a rotating position for the rotating block to rotate. The first rotating shaft and the second rotating shaft pass through the rotating position and are installed on the handle.

[0008] The rotating block is V-shaped, with the first and second locking positions located at the outer ends of the rotating block, and the inner end of the rotating block connected to a lever via a drive shaft.

[0009] The handle is formed by a first half-shell and a second half-shell, and the first half-shell and the second half-shell are respectively provided with a first stroke groove for the movement of the first rotating shaft and a second stroke groove for the movement of the second rotating shaft.

[0010] The lever is located outside the first half-shell, which has two recesses. One end of the lever is positioned within the recesses via a ball bearing, and the other end of the lever is connected to the inner end of the rotating block via a drive shaft.

[0011] The first half-shell is also provided with a limiting platform on the concave side.

[0012] A glue gun includes the aforementioned glue gun handle and a glue reservoir. The handle is connected to the glue reservoir via a push rod, and the glue reservoir extends out of the handle.

[0013] The storage medium is a gel cylinder.

[0014] The beneficial effects of this utility model are as follows: When the handle rotates along the first rotating shaft, the first locking position engages with the first rotating shaft, fixing the first rotating shaft. The handle drives the second rotating shaft to move along the handle body, which is one rotation stroke. At the same time, the handle drives the push rod to push the glue reservoir to squeeze out a glue amount of a certain distance. This rotation stroke determines one glue amount. When the handle rotates along the second rotating shaft, the second locking position engages with the second rotating shaft, fixing the second rotating shaft. The handle drives the first rotating shaft to move along the handle body, which is another rotation stroke. At the same time, the handle drives the push rod to push the glue reservoir to squeeze out another glue amount of a certain distance. This rotation stroke determines another glue amount. Thus, the glue gun's glue amount is adjustable, meeting the glue gun's glue amount requirements in different situations. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] like Figure 1 , 2 As shown, the glue gun handle includes a handle body, a handle 1, and a variable stroke mechanism. The variable stroke mechanism includes a rotating block 2, a first rotating shaft 3, a second rotating shaft 4, and a lever 5. The handle body is formed by a first half-shell 6 and a second half-shell 7, which are closed and fixed by screw posts. The first half-shell 6 and the second half-shell 7 are respectively provided with a first stroke groove 8 and a second stroke groove 9. One end of the handle 1 extends into the handle body, the rotating block 2 is built into the handle body, and one end of the handle 1 is provided with a rotation position 10. The first rotating shaft 3 and the second rotating shaft 4 pass through the rotation position 10 and are installed on the handle 1.

[0020] The rotating block 2 is V-shaped. The first locking position 11 and the second locking position 12 are respectively located at the outer end of the rotating block 2. The inner end of the rotating block 2 is connected to the lever 5 through the drive shaft 13. The lever 5 is located outside the first half shell 6. The first half shell 6 has two recesses 14. The first half shell 6 also has a limiting platform 15 on one side of the recesses 14. The other end of the lever 5 is connected to the inner end of the rotating block 2 through the drive shaft 13. The inner end of the rotating block 2 is rotatably connected through the positioning pin on the second half shell 7.

[0021] like Figure 1 , 2 As shown in Figure 3, the glue gun's glue reservoir is a glue cylinder 16, and the handle 1 is connected to the glue cylinder 16 via a push rod 17. The glue cylinder 17 extends out of the handle and is threadedly connected to the handle.

[0022] A ball bearing is provided at one end of the lever 5. When the lever 5 is turned, the lever 5 rotates along the drive shaft 13. When the ball bearing is limited to a concave point 14, a limiting platform 15 rotates to limit the lever 5, which is the first adjustment position. When the ball bearing is limited to the next concave point 14, the next limiting platform 15 rotates to limit the lever 5, which is the second adjustment position. The first adjustment position and the second adjustment position correspond to different rotation strokes of the handle relative to the handle body, thereby realizing the adjustability of the rotation stroke.

[0023] When the dial 5 is moved to the first adjustment position, the dial 5 drives the rotating block 2 to rotate at the rotating position 10 of the handle 1 through the transmission shaft 13, and the first locking position 11 is locked to the first rotating shaft 3. The first rotating shaft 3 is fixed. When the handle 1 rotates along the first rotating shaft 3, the handle 1 drives the second rotating shaft 4 to move along the second stroke groove 9 on the handle body, which is one rotation stroke. At the same time, the handle 1 drives the push rod 17 to push the glue cylinder 16 to extrude a distance of glue. This rotation stroke determines a glue output.

[0024] When the dial 5 is moved to the second adjustment position, the dial 5 drives the rotating block 2 to rotate at the rotating position 10 of the handle 1 through the transmission shaft 13, and the second locking position 12 is engaged with the second rotating shaft 4. The second rotating shaft 4 is fixed. When the handle 1 rotates along the second rotating shaft 4, the handle 1 drives the first rotating shaft 3 to move along the first stroke groove 8 on the handle body, which is another rotation stroke. At the same time, the handle 1 drives the push rod 17 to push the glue cylinder 16 to extrude another distance of glue. This rotation stroke determines another glue output.

[0025] If the distance of the first stroke groove is greater than the distance of the second stroke groove, then the glue output when adjusted to the second adjustment setting will be greater than the glue output when adjusted to the first adjustment setting. This achieves adjustable glue output for the glue gun, meeting the glue output requirements in different situations.
