Description

Technical Field

[0001] The utility model belongs to the technical field of glue guns, in particular to a glue gun with a retraction function. Background Art

[0002] The glue gun is a glue squeezing tool commonly used by individuals, families and factories. It can completely seal the gap to prevent water leakage. The glue gun uses the propulsion mechanism of the glue gun to propel the glue cartridge filled with glue. The glue gun basically includes a handle, a push rod and a propulsion device. The push rod runs through the handle. A glue cartridge rack is also provided at the front end of the glue cartridge rack. The glue cartridge is arranged on the glue cartridge rack. When the handle is pressed, the handle drives the propulsion device to be linked, so that the push rod is sent along the axial direction of the glue cartridge rack toward the glue outlet of the gun head, and the glue in the glue cartridge is discharged from the glue outlet. After the glue gun squeezes out a section of glue, when the hand stops squeezing, the pressure in the glue barrel is still increasing, so that the glue will continue to flow out some glue due to the release of the internal pressure, which makes the subsequent extrusion operation somewhat inconvenient, or inconvenient to collect, and wastes glue. At the same time, the glue will drip onto the workbench outside, causing the workbench to be dirty. Summary of the invention

[0003] The utility model aims to provide a glue gun with a retractable structure which has a simple structure and can reduce the waste of glue in a glue cylinder and can also prevent the glue liquid from dirtying a workbench.

[0004] The purpose of the utility model is achieved in this way:

[0005] A glue gun with a retraction function, comprising a handle and a glue cartridge holder provided at the front end of the handle. A push rod passing through the handle is provided on the handle. The front end of the push rod is located inside the glue cartridge holder and can move back and forth relative to the glue cartridge holder. A driving handle is provided on the handle, a pushing portion is provided on the driving handle, a driving block is provided on the push rod, the pushing portion abuts against the driving block, squeezing the driving handle can drive the driving block to move forward through the pushing portion. A first elastic member is provided in front of the driving block, the elastic member is sleeved on the push rod. Pressing the driving handle can squeeze the lower end of the driving block through the pushing portion, so that the driving block moves forward and drives the push rod to move forward. A locking member is provided on the push rod, a limiting block is provided at the upper end of the handle, the limiting block is located in front of the upper end of the locking member. An abutting portion is provided on the handle, the lower end of the locking member is located at the rear end of the abutting portion, a second elastic member is provided on the abutting portion, and the other end of the second elastic member abuts against the locking member. The locking member is inclined and clamped with the push rod. A limiting member is provided at the upper end of the handle, the limiting member is located behind the locking member and abuts against the upper end of the locking member. Pressing the driving handle to drive the push rod to move forward drives the locking member to move forward in parallel. The lower end of the locking member squeezes the second elastic member. When the upper end of the locking member moves to abut against the limiting block, the locking member disengages from the clamping with the push rod, and the push rod moves forward alone to complete glue application. When the driving handle is released, the locking member inclines to be clamped with the push rod, and drives the locking member and the push rod to retract to abut against the limiting member through the resilience of the second elastic member, and limits the push rod from continuing to move backward. The retraction distance of the push rod and the locking member is related to the distance between the front limiting block and the upper end of the locking member before driving.

[0006] Further, a first limiting portion and a second limiting portion are provided on the limiting block. The distance between the first limiting portion and the locking member is less than the distance between the second limiting portion and the locking member. A conversion member for driving the limiting block to rotate is provided on the limiting block.

[0007] Further, a rotating portion is integrally formed and protruded on the limiting block, a rotating groove is formed on the rotating portion. The conversion member is provided with a connecting portion and a transmission portion. One end of the transmission portion is connected to the conversion member, and the other end is connected to the connecting portion. The transmission portion is inserted into the rotating groove. The connecting portion is located at the rear end of the rotating portion. When the conversion member is driven to move forward, the connecting portion abuts against the rotating portion and pulls the rotating portion to rotate, so that the limiting member block rotates downward until the first limiting portion is located at the front end of the locking member.

[0008] Further, an abutting portion adapted to the rotating portion is further provided on the limiting member block. When the conversion member is driven to move backward, the connecting portion abuts against the abutting portion and squeezes the abutting portion, so that the limiting member block rotates downward until the first limiting portion is located at the front end of the locking member.

[0009] Furthermore, a driving part and a limiting plate are also provided on the conversion part. The driving part is exposed on the upper surface of the handle, and the limiting plate is located inside the handle. A conversion hole is provided on the handle. The upper end of the conversion part passes through the conversion hole. The driving part is located at the upper end of the conversion part and is exposed from the conversion hole. The limiting block is larger than the conversion hole and abuts against the periphery of the lower end of the rotation hole.

[0010] Furthermore, a limiting part is provided at the upper end of the handle. The limiting part is located behind the locking part and abuts against the upper end of the locking part. There is a gap between the limiting part and the limiting block. The upper end of the locking part is located in the gap between the limiting part and the limiting block.

[0011] Furthermore, a limiting hole is provided on the locking part, and the push rod passes through the limiting hole. The locking part is connected to the push rod through the limiting hole.

[0012] Furthermore, a rotating shaft is provided inside the handle. A rotation hole is provided on the limiting block, and the rotating shaft passes through the rotation hole. The limiting block can rotate around the rotating shaft.

[0013] Furthermore, a pressing part is provided on the locking part. The pressing part is provided at the rear end of the locking part. A clamping hole is provided on the locking part. A clamping block is provided on the pressing part. The clamping block is connected to the clamping hole. The pressing part is connected to the locking part through the clamping part. Clamping parts are bent and provided on both sides of the front end of the pressing part. The clamping parts are clamped with the lower end of the locking part.

[0014] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0015] The purpose of the present utility model is to provide a glue gun with a simple structure, which can reduce the waste of glue in the glue cylinder and avoid the glue liquid from soiling the workbench. The glue gun includes a handle and a glue cylinder holder arranged at the front end of the handle. A push rod passing through the handle is provided on the handle. The front end of the push rod is located inside the glue cylinder holder and can move back and forth relative to the glue cylinder holder. A driving handle is provided on the handle, and a pushing part is provided on the driving handle. A driving block is provided on the push rod, and the pushing part abuts against the driving block. Squeezing the driving handle can drive the driving block to move forward through the pushing part. A first elastic member is provided in front of the driving block, and the elastic member is sleeved on the push rod. Pressing the driving handle can squeeze the lower end of the driving block through the pushing part, so that the driving block moves forward and drives the push rod to move forward. A locking member is provided on the push rod, and a limiting block is provided at the upper end of the handle. The limiting block is located in front of the upper end of the locking member. An abutting part is provided on the handle, and the lower end of the locking member is located at the rear end of the abutting part.

The locking member is inclined and clamped with the push rod. A limiting member is provided at the upper end of the handle, and the limiting member is located behind the locking member and abuts against the upper end of the locking member. Pressing the driving handle to drive the push rod to move forward will drive the locking member to move forward in parallel. The lower end of the lock presses the second elastic member. When the upper end of the locking member moves to abut against the limiting block, the locking member disengages from the clamping with the push rod, and the push rod moves forward alone to complete glue application. When the driving handle is released, the locking member is inclined to be clamped with the push rod, and the locking member and the push rod are driven back to abut against the limiting member through the resilience of the second elastic member, and the continued backward movement of the push rod is restricted, rather than remaining in the feeding position like the push rods on the current market, avoiding the phenomenon that glue continues to flow out from the glue outlet of the glue cylinder, solving the problem that when the glue gun stops applying glue and the push rod is still in the feeding position, a part of the glue liquid can still drip onto the outside workbench, effectively preventing the dripping and waste of the glue liquid, ensuring the cleanliness of the workbench. The backward movement distance of the push rod and the locking member is related to the distance between the limiting block and the upper end of the locking member before driving. By adjusting the distance between the limiting block and the locking member, the backward movement distance of the push rod can be controlled. BRIEF DESCRIPTION OF THE DRAWINGS

When the upper end of the locking member 10 moves to abut against the limiting block 13, the locking member 10 disengages from the engagement with the push rod 3, and the push rod 3 moves forward alone to complete glue application. When the driving handle 6 is released, the locking member 10 is inclined to engage with the push rod 3, and the locking member 10 and the push rod 3 are driven to retract by the resilience of the second elastic member 36. The retraction distance of the push rod 3 and the locking member 10 is related to the distance between the limiting block 13 and the upper end of the locking member 10 before driving.

[0033] The purpose of the present utility model is to provide a glue gun with a simple structure, which can reduce the waste of glue in the glue cylinder and avoid soiling the workbench with the glue.

When pressing the driving handle 6 to drive the push rod 3 to move forward, the locking member 10 is driven to move forward in parallel. The lower end of the locking member 10 squeezes the second elastic member 36. When the upper end of the locking member 10 moves to abut against the limiting block 13, the locking member 10 disengages from the clamping with the push rod 3, and the push rod 3 moves forward alone to complete glue application. When the driving handle 6 is released, the locking member 10 is inclined to be clamped with the push rod 3, and the locking member 10 and the push rod 3 are driven to retreat to abut against the limiting member 29 through the resilience of the second elastic member 36, and the continuous backward movement of the push rod 3 is restricted, rather than the push rod 3 being still in the feeding position like the current push rods on the market, avoiding the phenomenon that the glue continues to flow out from the glue outlet of the glue cylinder, solving the problem that when the glue gun stops applying glue and the push rod 3 is still in the feeding position, part of the glue can still drip onto the outside workbench, effectively preventing the dripping and waste of the glue, ensuring the cleanliness of the workbench. The retreat distance of the push rod 3 and the locking member 10 is related to the distance between the front limiting block 13 and the upper end of the locking member 10 before driving. By adjusting the distance between the limiting block 13 and the locking member 10, the retreat distance of the push rod 3 can be controlled.

A conversion member 19 for driving the limiting block 13 to rotate is provided on the limiting block 13. The conversion member 19 is exposed on the upper surface of the handle 2. When the first limiting portion 17 is in front of the locking member 10, the stroke generated by the backward movement of the locking member 10 is less than the stroke generated by the backward movement of the locking member 10 when the second limiting portion 18 is in front of the locking member 10.
