Description

Technical Field

[0001] This utility model relates to the field of glue gun technology, and in particular to a two-component pneumatic glue gun with a bracket and large and small glue tubes. Background Technology

[0002] In our daily lives and work, we often face various tasks involving bonding, filling, patching, and coating. For example, we need to bond and patch different objects together, fill, seal, and repair holes and gaps, or coat and recreate objects. Undoubtedly, such operations require the delivery of various extrudable and fluid media such as adhesives, silicone sealants, pastes, or fillers to specific target areas.

[0003] Existing technologies primarily employ manual, pneumatic, and electric glue guns. Pneumatic glue guns are powered by compressed gas, which pushes the glue from the bottom using pressure. Compressed air is typically used, and adjusting the pressure controls the amount of glue dispensed. Pneumatic glue guns also include two-component glue guns, which can be used to apply two glues simultaneously to meet specific application requirements. However, in existing two-component glue guns, the glue tube holders are often left open and unrestricted above for easy top-down assembly and disassembly of the two-component glue tubes. This allows the glue tubes to occasionally detach from the holder during use, affecting stability. Furthermore, when the two glue tubes differ significantly in size, space constraints often result in the smaller tube being unsupported and poorly secured when the larger tube is properly anchored, further compromising stability. Utility Model Content

[0004] Therefore, it is necessary to address the problems existing in current two-component glue guns by providing a bracket that facilitates the disassembly and assembly of two-component glue tubes and offers good stability during use, as well as a two-component pneumatic glue gun with both large and small glue tubes.

[0005] A bracket includes: a front cover and a rear cover disposed opposite to each other; an upper connecting plate connected to the upper side of the front cover and the upper side of the rear cover at both ends respectively; a lower connecting plate connected to the lower side of the front cover and the lower side of the rear cover at both ends respectively; a rear connecting plate connected to the rear side of the front cover and the rear side of the rear cover at both ends respectively; and a support block mounted on the rear connecting plate; the front cover has an elongated opening; a disassembly / assembly port is formed between the front cover, the rear cover, the upper connecting plate, and the lower connecting plate, communicating with the elongated opening and disposed opposite to the rear connecting plate; and the support block is disposed opposite to the disassembly / assembly port.

[0006] The front cover, rear cover, upper connecting plate, and lower connecting plate of the aforementioned bracket form a disassembly / removal port that communicates with the elongated opening and is positioned opposite the rear connecting plate. During use, the two-component hose is quickly inserted into the bracket through this port, at which point the dispensing mixing head extends from the elongated opening. Because the elongated opening of the front cover and the upper connecting plate create an overhead confinement space, the two-component hose is effectively secured and prevented from detaching from the bracket during use. Furthermore, the support block provides lateral support and fixation for the small hose, ensuring good stability during use. The disassembly / removal port also guarantees convenient installation and removal of the two-component hose.

[0007] In one embodiment, the front cover is provided with two guide arc surfaces arranged vertically opposite each other, and the guide arc surfaces are located at the opening of the elongated opening away from the rear connecting plate.

[0008] In one embodiment, the front end cover has a first upper notch, a first lower notch and a first rear notch, and the rear end cover has a second upper notch, a second lower notch and a second rear notch; the two ends of the upper connecting plate are respectively connected to the first upper notch and the second upper notch; the two ends of the lower connecting plate are respectively connected to the first lower notch and the second lower notch; and the two ends of the rear connecting plate are respectively connected to the first rear notch and the second rear notch.

[0009] In one embodiment, the support block is provided with an arc-shaped opening, which is positioned opposite to the disassembly / assembly operation port.

[0010] This utility model also provides a two-component pneumatic glue gun with large and small hoses, including: the bracket mentioned above, a cylinder assembly connected to the bracket, a main gun body connected to the cylinder assembly, a first piston rod connected to the cylinder assembly, a second piston rod connected to the cylinder assembly, a first push plate installed on one end of the first piston rod and located in the bracket, and a second push plate installed on one end of the second piston rod and located in the bracket.

[0011] The aforementioned two-component pneumatic glue gun with large and small hoses features a disassembly and assembly port formed by the front and rear caps, upper and lower connecting plates of the bracket, which communicates with the elongated opening and is positioned opposite the rear connecting plate. During use, the two-component hose is quickly inserted into the bracket through this port, at which point the dispensing head extends from the elongated opening. The elongated opening of the front cap and the upper connecting plate create an overhead confinement space, effectively securing the two-component hose and preventing it from detaching from the bracket during use. Furthermore, the support block provides side support for the smaller hose, preventing it from dangling and ensuring good stability. The disassembly and assembly port also ensures convenient installation and removal of the hose. Therefore, this two-component pneumatic glue gun with large and small hoses is very convenient and stable to use.

[0012] In one embodiment, the cylinder assembly includes a cylinder body, a piston movably mounted in the cylinder body, and piston rings mounted on the piston, the piston rings abutting against the inner wall of the cylinder body, and the piston being connected to a first piston rod and a second piston rod.

[0013] In one embodiment, the cylinder assembly further includes a gas seal ring mounted on the piston, the gas seal ring being located on the side of the piston ring away from the first piston rod and abutting against the inner wall of the cylinder body.

[0014] In one embodiment, the main gun body includes a main shell with an internal air passage and connected to the cylinder, a vent handle and a vent button mounted on the main shell, and an air inlet connector mounted on the bottom of the main shell.

[0015] In one embodiment, an air volume regulating valve is installed on the air intake connector.

The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only; for example, “inner,” “outer,” “left,” “right,” and similar expressions are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] Please refer to Figures 1 to 3 This is a schematic diagram of the bracket 100 of this utility model. The bracket 100 is connected and fixed to the cylinder assembly of a pneumatic glue gun, and serves to install and fix the two-component glue tube. The bracket 100 includes: a front end cover 20 and a rear end cover 30 arranged opposite each other; an upper connecting plate 41 connected to the upper side of the front end cover 20 and the upper side of the rear end cover 30 at both ends; a lower connecting plate 42 connected to the lower side of the front end cover 20 and the lower side of the rear end cover 30 at both ends; a rear connecting plate 43 connected to the rear side of the front end cover 20 and the rear side of the rear end cover 30 at both ends; and a support block 44 mounted on the rear connecting plate 43. An elongated opening 21 is opened on the front end cover 20. A disassembly and assembly operation port 22 is formed between the front end cover 20, the rear end cover 30, the upper connecting plate 41, and the lower connecting plate 42, which communicates with the elongated opening 21 and is arranged opposite to the rear connecting plate 43. The support block 44 is arranged opposite to the disassembly and assembly operation port 22.

[0027] Furthermore, the rear end plate 30 is provided with at least two through holes 31, through which the piston rod can pass. To facilitate the installation of the rear end cover 30, the rear end cover 30 is provided with four screw holes 32, and the rear end cover 30 is installed and fixed by screws during use.

[0028] Furthermore, the front cover 20 is provided with two guide arc surfaces 23 arranged vertically opposite each other, and the guide arc surfaces 23 are located at the opening of the elongated opening 21 away from the rear connecting plate 43. The two guide arc surfaces 23 form a horn-shaped guide space, which facilitates the installation of the two-component hose into the bracket 100 from the side disassembly and assembly port 22.

[0029] Furthermore, the front end cover 20 has a first upper notch 24, a first lower notch 25, and a first rear notch 26, and the rear end cover 30 has a second upper notch 33, a second lower notch 34, and a second rear notch 35. The two ends of the upper connecting plate 41 are connected to the first upper notch 24 and the second upper notch 33, respectively; the two ends of the lower connecting plate 42 are connected to the first lower notch 25 and the second lower notch 34, respectively; and the two ends of the rear connecting plate 43 are connected to the first rear notch 26 and the second rear notch 35, respectively.

[0030] Furthermore, the support block 44 is provided with an arc-shaped opening 45, which is positioned opposite to the disassembly / removal operation port 22. The arc-shaped opening 45 allows the support block 44 to fit more closely to the outer wall of the small rubber tube, resulting in better stability of the support. In this embodiment, the support block 44 is located in the middle of the rear connecting plate 43, thus providing a more balanced supporting force.

[0031] The front cover 20, rear cover 30, upper connecting plate 41, and lower connecting plate 42 of the aforementioned bracket 100 form a disassembly / assembly port 22 that communicates with the elongated opening 21 and is positioned opposite to the rear connecting plate 43. In use, the two-component hose is quickly installed into the bracket through the disassembly / assembly port 22, at which point the dispensing mixing head extends from the elongated opening. Because the elongated opening 21 of the front cover and the upper connecting plate 41 form an upper restrictive space, they effectively restrict and fix the two-component hose, preventing it from detaching from the bracket 100 during use. Furthermore, the support block 44 provides support and fixation to the side of the small hose, ensuring good stability during use. The disassembly / assembly port 22 also ensures convenient disassembly and assembly of the two-component hose.

[0032] On the other hand, please refer to... Figures 4 to 6 This utility model provides a two-component pneumatic glue gun 200 with large and small tubing. The two-component pneumatic glue gun 200 includes the aforementioned bracket 100, a cylinder assembly 50 connected to the bracket 100, a main gun body 60 connected to the cylinder assembly 50, a first piston rod 71 connected to the cylinder assembly 50, a second piston rod 72 connected to the cylinder assembly 50, a first push plate 81 mounted on one end of the first piston rod 71 and located within the bracket 100, and a second push plate 82 mounted on one end of the second piston rod 72 and located within the bracket 100. The first piston rod 71 and the first push plate 81 cooperate to compress the glue in the smaller tubing of the two-component glue gun, while the second piston rod 72 and the second push plate 82 cooperate to compress the glue in the larger tubing of the two-component glue gun. In this embodiment, the size ratio between the large and small tubing can be 10:1.

[0033] Furthermore, the cylinder assembly 50 includes a cylinder body 51, a piston 52 movably mounted within the cylinder body 51, and a piston ring 53 mounted on the piston 52. The piston ring 53 abuts against the inner wall of the cylinder body 51, and the piston 52 is connected to a first piston rod 71 and a second piston rod 72. To further improve sealing, the cylinder assembly 50 also includes an air seal ring 54 mounted on the piston 52. The air seal ring 54 is located on the side of the piston ring 53 away from the first piston rod 71 and abuts against the inner wall of the cylinder body 51. In use, the piston 52 can move within the cylinder body 51 under air pressure, thereby driving the first push plate 81 and the second push plate 82 to extrude the adhesive in the two-component adhesive tube through the adhesive mixing head, thus completing the adhesive dispensing drive.

[0034] Furthermore, the main gun body 60 includes a main shell 61 with an internal air passage (not shown) and connected to the cylinder 51, a vent handle 62 and a vent button 63 mounted on the main shell 61, and an air inlet connector 64 mounted on the bottom of the main shell 61. The piston 52 divides the interior of the cylinder 51 into a first air chamber (not shown) and a second air chamber (not shown). In use, the piston 52 is connected to the first air chamber via a first vent pipe 65 and to the second air chamber via a second vent pipe 66. The first vent pipe 65 and the second vent pipe 66 are connected to the air passage via the vent handle 25 and the vent button 63. The vent handle 25 controls the air intake through the air passage and either the first vent pipe 65 or the second vent pipe 66. The vent button 63 can switch the air supply through the air passage and either the first vent pipe 65 or the second vent pipe 66, thereby controlling the direction of movement of the piston 52.

[0035] Furthermore, an air volume regulating valve 67 is installed on the air inlet connector 64. The air volume regulating valve 67 is used to regulate the amount of air entering from the external air source. To improve service life, a few drops of lubricating oil are applied to the interface of the air inlet connector 64. In this embodiment, to facilitate gripping the main gun body 60, a hand-held limiting component 68 is provided on the main body shell 61, making the grip more stable during use. In this embodiment, the main body shell 61 is assembled from a left main body shell cover and a right main body shell cover.

[0036] The aforementioned two-component pneumatic glue gun 200 with large and small tubing has a disassembly / assembly port 22 formed between the front cover 20, rear cover 30, upper connecting plate 41, and lower connecting plate 42 of the bracket 100. This port communicates with the elongated opening 21 and is positioned opposite the rear connecting plate 43. During use, the two-component tubing is quickly installed into the bracket 100 through the disassembly / assembly port 22, at which point the dispensing mixing head extends from the elongated opening 21. Because the elongated opening 21 of the front cover 20 and the upper connecting plate 41 form an upper restrictive space, the two-component tubing is restrained and fixed, preventing it from detaching from the bracket 100 during use. Furthermore, the support block 44 provides support and fixation to the side of the smaller tubing, preventing it from being suspended in the air, resulting in good stability. The disassembly / assembly port 22 also ensures convenient disassembly and assembly of the two-component tubing. Therefore, the two-component pneumatic glue gun 200 with large and small tubing is very convenient and stable to use.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
