Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass glue guns. Background Technology
[0002] Glass glue is a material used to bond and seal various types of glass to other substrates. When squeezing glass glue out of the container, a glass glue gun is required. Existing glass glue guns generally include a gun body, a push rod, a push head, and a push rod pushing device. The gun body is provided with a glass glue placement groove, and a push rod is placed in the glass glue placement groove. One end of the push rod is fixed with a push head, and the other end of the push rod extends out of the gun body and is bent. The gun body is provided with a push rod switch for locking the push rod. At the same time, the push rod pushing device is used to drive the push rod forward a certain distance, so that the push head can squeeze the glass glue to achieve glue dispensing.
[0003] However, the dispensing volume of existing glass glue guns is not adjustable; that is, the distance the push rod moves forward is fixed. This is inconvenient to use because existing glass glue guns cannot achieve the desired dispensing volume, resulting in less aesthetically pleasing finished products for beginners. Furthermore, existing glass glue guns tend to drip after use because the push rod is constantly under pressure. This results in a significant amount of solidified glue remaining at the nozzle for the next use, which is troublesome to clean and makes storage unsanitary. Utility Model Content
[0004] In view of the shortcomings of existing glass glue guns, the technical problem to be solved by this utility model is to provide a glass glue gun with a glue dispensing function; at the same time, the glass glue gun also needs to solve the problem of glue dripping after use.
[0005] To achieve the above objectives, according to one aspect of this utility model, the present utility model is implemented through the following technical measures: a multi-level adjustable glass glue gun, comprising: a gun body, the gun body having a glass glue placement groove, a push rod being disposed within the glass glue placement groove, a push head fixed to one end of the push rod, and the other end of the push rod extending out of the gun body and bent; the gun body having a push rod switch for locking the push rod; the glass glue gun further comprising a push rod pushing device, the push rod pushing device comprising a power head, a return spring, a handle, and a level adjustment rod, the handle... One end is hinged to the gun body, and two vertically arranged and connected gear slots are provided at the hinge end of the handle. The gear adjustment rod is inserted into one of the gear slots and can move into the other gear slot. The power head is tightly fitted onto the push rod, and a return spring is provided on the side of the power head opposite to the push head. The return spring is fitted onto the push rod, with one end of the return spring abutting against the power head and the other end abutting against the gun body. The lower end of the power head abuts against the gear adjustment rod. By squeezing the handle, the gear adjustment rod can push the power head to move, thereby moving the push rod forward a certain distance.
[0006] This multi-speed adjustable caulking gun uses two vertically arranged and connected speed slots and a speed adjustment lever. The speed adjustment lever can be adjusted up and down. By pressing the handle, the distance the speed adjustment lever moves to the power head can be changed, thus achieving the effects of fast and slow caulking.
[0007] Furthermore, the gun body is composed of a left gun body and a right gun body, the glass glue placement groove is provided on the gun body, the right gun body has a storage hole in the center, and the power head and return spring are located in the storage hole.
[0008] Furthermore, the push rod switch includes a switch body, a stop head, and a spring. The switch body is sleeved on the push rod, and the spring tilts the switch body to lock the push rod. The upper end of the switch body is provided with a U-shaped stop head, which is stuck on the gun body. Two stops head are provided on the gun body to block the stop head.
[0009] Furthermore, the gun body is equipped with two linked drip-proof switches via a rotating shaft, and one of the drip-proof switches has a rotating rod. By rotating the rod, the drip-proof switch can abut against the U-shaped abutment, preventing the switch body from resetting and locking the push rod. In this design, when the drip-proof switch abuts against the U-shaped abutment, the push rod's thrust is always present. When the drip-proof switch is not in contact with the U-shaped abutment, the return spring causes the push rod to reset a short distance.
[0010] Furthermore, a latch is provided on one side of the gear slot, and a latch is provided on one side of the gear adjustment rod. The other end of the gear adjustment rod passes through the gear slot so that the latch can engage with the latch. A button head is fixed to the protruding side of the gear adjustment rod by a screw. A compression spring is also provided on the gear adjustment rod between the button head and the handle to contact both.
[0011] Compared with the prior art, the advantages of this utility model are: it realizes the design of dispensing speed, so that the dispensing speed can be fast or slow according to the user's needs. At the same time, through the design of anti-drip switch, when in normal use, the anti-drip switch prevents the push rod from resetting, and when not in use, the anti-drip switch can be turned on, and the push rod can move backward a small distance, so it will not be constantly pressed against the glass glue.

Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0019] Example 1
[0020] Please refer to Figures 1-3This embodiment provides a multi-level adjustable glass glue gun, comprising: a gun body 1, a push rod 3, a push head 4, a push rod switch 5, and a push rod pushing device. The gun body 1 is composed of an integral left gun body 10 and a right gun body 11. The upper end of the left gun body 10 has a glass glue placement groove 2, and the push rod 3 is disposed in the glass glue placement groove 2. The push head 4 is fixed to the left end of the push rod 3, and the right end of the push rod 3 extends out of the right gun body 11 and is bent. The push rod switch 5 is prior art and includes a switch body 13, a stop head 14, a U-shaped abutment 22, and a spring 15. The switch body 13 is sleeved on the push rod 3, and the spring 15, which contacts the lower side of the switch body 13, tilts the switch body 13 to lock the push rod 3. The U-shaped abutment 22 is fixed to the upper side of the switch body 13, and the center of the U-shaped abutment 22 is locked onto the right gun body 11. The stop head 14 is also fixed to the right gun body 11 to provide a stop for the right side of the U-shaped abutment 22. The right gun body 11 contains... The device also has a storage hole 12. The aforementioned push rod pushing device includes a power head 6, a return spring 7, a handle 8, and a gear adjustment rod 9. The upper end of the handle 8 is hinged to the right gun body 11 by a pin, and two vertically arranged and connected gear slots are opened at the hinge end of the handle 8. The gear adjustment rod 9 is inserted into one of the gear slots and can move into the other gear slot. The power head 6 is tightly fitted onto the push rod 3, and the return spring 7 is provided on the side of the power head 6 opposite to the push head 4, that is, on the left side. The return spring 7 is fitted onto the push rod 3, and the right end of the return spring 7 abuts against the power head 6, and the left end abuts against the left side of the right gun body 11. The power head 6 and the return spring 7 are both located in the aforementioned storage hole 12. The lower end of the power head 6 abuts against the gear adjustment rod 9. By squeezing the handle 8, the gear adjustment rod 9 can tilt and push the power head 6 to move and squeeze the return spring 7, thereby causing the push rod 3 to move forward a certain distance.
[0021] As a preferred structure, a latch 18 is provided on one side of the gear slot, and a latch 20 is provided on one side of the gear adjustment rod 9. The other end of the gear adjustment rod 9 passes through the gear slot so that the latch 20 can engage with the latch 18. A button head 19 is fixed to the protruding side of the gear adjustment rod 9 by screws. A compression spring 21 is also sleeved on the gear adjustment rod 9 between the button head 19 and the handle 8, which contacts both. In this way, when the gear does not need to be adjusted, the latch 20 is engaged with the latch 18. When the gear needs to be adjusted, the latch 20 is disengaged from the latch 18 by pressing the button head 19. At the same time, the push rod switch 5 cannot limit the push rod 3 (the principle here is that the power head will drive the push rod to move during adjustment, so it cannot be limited). In this way, the gear adjustment rod can be pushed up and down. The principle of the gear adjustment rod 9 being adjustable is that when it is fixed in the two gear slots, the contact position with the lower end of the power head 6 is different. The pushing force near the lower end will be greater than that at the upper end.
[0022] Meanwhile, the gun body is equipped with two interlocking anti-drip switches via a rotating shaft, and one of the anti-drip switches has a rotating rod. By rotating the rod, the anti-drip switch can press against the U-shaped abutment, preventing the switch body from resetting and locking the push rod. When in normal use, the anti-drip switch prevents the push rod from resetting, while when not in use, opening the anti-drip switch allows the push rod to move backward a small distance, thus preventing it from constantly pressing against the silicone sealant.
