In addition, the term "connected" and / or "coupled" to another element can refer to either a direct connection between the elements, or an indirect connection through intervening elements. Furthermore, "and / or" is a conjunctive term, not an exclusive one, and is intended to mean that the associated objects can exist singly or in combination.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the content clearly dictates otherwise. Thus, for example, reference to "a component" includes a combination of two or more components, and the like.

[0026] Please refer to Figures 1 to 3 , the schematic diagram of the hose bracket 100 of the present application, the hose bracket 100 is connected and fixed with the cylinder assembly of the two-component pneumatic glue gun, and plays a role of installation and fixation for the two-component hose. The hose bracket 100 comprises: oppositely arranged front end cover 20 and rear end cover 30, upper connecting plate 41 connected at the upper side of the front end cover 20 and the upper side of the rear end cover 30 at both ends, lower connecting plate 42 connected with the lower side of the front end cover 20 and the lower side of the rear end cover 30 at both ends, and rear connecting plate 43 connected with the rear side of the front end cover 20 and the rear side of the rear end cover 30 at both ends. A long slot 21 is formed on the front end cover 20, and a dismounting 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 is in communication with the long slot 21 and is oppositely arranged with the rear connecting plate 43.

[0027] Further, the rear end cover 30 is provided with at least two rod penetrating holes 31, through which the piston rod is conveniently penetrated. In order to facilitate the installation of the rear end cover 30, four screw holes 32 are provided on the rear end cover 30, which are used to install and fix the rear end cover 30 by screws.

[0028] Further, the front end cover 20 is provided with two oppositely arranged guide arc surfaces 23, which are located at the opening of the long slot 21 away from the rear connecting plate 43. The two guide arc surfaces 23 form a horn guide space, which facilitates the installation of the two-component hose into the hose bracket 100 through the side dismounting operation port 22.

[0029] Further, the front end cover 20 is provided with a first upper notch 24, a first lower notch 25 and a first rear notch 26, and the rear end cover 30 is provided with 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 with the first upper notch 24 and the second upper notch 33 respectively, the two ends of the lower connecting plate 42 are connected with the first lower notch 25 and the second lower notch 34 respectively, and the two ends of the rear connecting plate 43 are connected with the first rear notch 26 and the second rear notch 35 respectively. In the embodiment, the number of the rear connecting plate 43, the first rear notch 26 and the second rear notch 35 is two, so that two groups of rear limiting surfaces are formed.

[0030] The front end cover 20, the rear end cover 30, the upper connecting plate 41 and the lower connecting plate 42 of the hose bracket 100 form a dismounting operation opening 22 which is communicated with the long slot 21 and is opposite to the rear connecting plate 43. When in use, the two-component hose is quickly mounted into the hose bracket 100 from the dismounting operation opening 22, and the glue outlet mixing head extends out of the long slot 21. Since the long slot 21 of the front end cover 20 and the upper connecting plate 41 form an upper limiting space, the two-component hose is limited and fixed, and will not be loosened from the hose bracket 100 when in use, so that the stability is good, and the dismounting convenience of the two-component hose is ensured.

[0031] On the other hand, referring again to Figures 4 to 6 The utility model provides a two-component pneumatic glue gun 200, which comprises the above-mentioned hose bracket 100, a cylinder assembly 50 connected with the hose bracket 100, a main gun body 60 connected with the cylinder assembly 50, two piston rods 70 connected with the cylinder assembly 50, and a push plate 80 mounted on one end of the piston rod 70 and located in the hose bracket 100.

[0032] Further, the cylinder assembly 50 comprises a cylinder body 51, a piston 52 movably mounted in the cylinder body 51, and a piston ring 53 mounted on the piston 52 and abutting against the inner wall of the cylinder body 51, and the piston 52 is connected with the piston rod 70. In order to further improve the sealing performance, the cylinder assembly 50 further comprises a gas seal ring 54 mounted on the piston 52, which is located on the side of the piston ring 53 away from the piston rod 70 and abuts against the inner wall of the cylinder body 51. When in use, the piston 52 can move in the cylinder body 51 under the driving of the gas pressure, and then drives the push plate 80 to extrude the glue in the two-component hose through the glue outlet mixing head, so as to complete the glue driving.

[0033] Further, the main gun body 60 comprises a main body shell 61 with an air passage (not shown) inside and connected with the cylinder body 51, a ventilation handle 62 and a ventilation button 63 mounted on the main body shell 61, and an air inlet connector 64 mounted on the bottom of the main body shell 61. The piston 52 divides the cylinder body 51 into a first air chamber (not shown) and a second air chamber (not shown). In use, the first ventilation pipe 65 is in communication with the first air chamber, and the second ventilation pipe 66 is in communication with the second air chamber. The first ventilation pipe 65 and the second ventilation pipe 66 are in communication with the air passage through the ventilation handle 25 and the ventilation button 63. The ventilation handle 25 controls the air intake of the air passage and the first ventilation pipe 65 or the second ventilation pipe 66. The ventilation button 63 can switch the air supply of the air passage and the first ventilation pipe 65 or the second ventilation pipe 66, thereby controlling the moving direction of the piston 52.

[0034] Further, the air volume adjusting valve 67 is mounted on the air inlet connector 64, which is used to adjust the air volume of the external air source. In order to improve the service life, a few drops of lubricating oil are dripped on the interface of the air inlet connector 64. In the embodiment, in order to facilitate the holding of the main gun body 60, the main body shell 61 is provided with a hand holding limiting part 68, so that the fingers can hold more stably in use. In the embodiment, the main body shell 61 is assembled by a main body shell left cover and a main body shell right cover.

[0035] The double-component pneumatic glue gun 200 has a dismounting operation port 22 formed between the front end cover 20, the rear end cover 30, the upper connecting plate 41 and the lower connecting plate 42 of the glue pipe bracket 100, which is in communication with the long slot 21 and is opposite to the rear connecting plate 43. In use, the double-component glue pipe is quickly mounted into the glue pipe bracket 100 from the dismounting operation port 22, and the glue mixing head is extended from the long slot 21 at this time. Because the long slot 21 of the front end cover 20 and the upper connecting plate 41 form an upper limiting space, the double-component glue pipe is limited and fixed, and will not be loosened from the glue pipe bracket 100 in use, which is good in stability. The dismounting operation port 22 ensures the convenience of dismounting the double-component glue pipe, so that the double-component pneumatic glue gun 100 is very convenient and stable to use.
