Description

Technical Field

[0001] This utility model relates to the field of glue gun equipment technology, and in particular to a simple two-component glue gun. Background Technology

[0002] A caulking gun is a tool for applying caulking agent. To improve the drying effect of polyurethane foam sealant, it can be mixed with a drying aid (curing agent).

[0003] Most caulking guns on the market for extruding polyurethane foam sealant are industrial products, inconvenient to operate, and some require electricity, making them unsuitable for simple household tasks. To better suit household tasks and reduce the professional requirements for operation, several dual-channel, two-component caulking guns have been launched on the market. For example, Chinese utility model patent CN202321001272.4 discloses a portable aerosol-type two-component raw material mixing and dispersion system. In this system, the left end of the gun body is connected to a mixing tube for mixing two components, A and B. Component A flowing from the aerosol A component tube and component B flowing from the aerosol B component tube both enter the mixing tube for mixing and are then sprayed out after mixing. In practical applications, since components A and B react in the mixing tube, adhesive can be continuously dispensed during the first use. However, upon reuse, some reactants remain in the mixing tube and solidify, clogging it and preventing smooth dispensing. This necessitates replacing the mixing tube, which is cumbersome. Furthermore, if the blockage occurs at the connection between the mixing tube and the nozzle, disassembly of the mixing tube may become difficult. Additionally, because the mixing tube is disposable, the aforementioned glue gun requires multiple mixing tubes, resulting in high material costs and significant waste. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a simple two-component glue gun.

[0005] The technical solution adopted in this utility model is: a simple two-component glue gun, comprising:

[0006] The gun holder body is equipped with a first feeding assembly and a second feeding assembly. The first feeding assembly is provided with a first input pipe, and the second feeding assembly is provided with a second input pipe.

[0007] A hose is installed on the gun holder body and passes through the first feeding assembly. The hose extends in the front-to-back direction and has an inlet hole.

[0008] A drying agent tube is mounted on the second feeding assembly at its rear end and extends in the front-to-back direction. The drying agent tube is sleeved on the front part of the rubber tube and cooperates with the rubber tube to form a flow channel. The second input pipe is connected to the flow channel. The front end of the drying agent tube is provided with a gun head. The rubber tube passes through the gun head. An output channel is provided between the gun head and the outer wall of the rubber tube. An opening and closing structure is provided between the gun head and the rubber tube to adjust whether the flow channel and the output channel are connected. A wrench is hinged to the gun body and has a loose state and a pressing state. In the loose state, the first input pipe and the inlet hole are disconnected, and the opening and closing structure is closed. In the pressing state, the wrench drives the rubber tube to move backward relative to the drying agent tube, the first input pipe and the inlet hole are connected, the opening and closing structure is opened, the foaming adhesive in the first input pipe enters the rubber tube through the inlet hole, and the drying agent in the flow channel enters the output channel.

[0009] A return spring is disposed in the gun holder body and abuts against the rear end of the hose.

[0010] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0011] Preferably, the opening and closing structure includes a wedge-shaped surface disposed on the outer wall of the hose and a guide slope disposed at the rear end of the gun head. A closing point is formed between the front end of the guide slope and the rear end of the output channel. In the released state, the closing point abuts against the wedge-shaped surface and isolates the flow channel and the output channel. In the pressed state, the closing point leaves the wedge-shaped surface, and the flow channel and the output channel are connected.

[0012] Preferably, the upper end of the first feeding component is provided with a first mounting port that is matched and connected to the foamed adhesive tank. The first feeding component also includes a first sleeve for the adhesive tube to pass through. The first input pipeline is disposed between the first mounting port and the first sleeve. In the loosened state, the inner wall of the first sleeve isolates the connection between the first input pipeline and the inlet hole.

[0013] Preferably, the upper end of the second feeding assembly is provided with a second mounting port that is connected to the drying agent tank. The second feeding assembly also includes a second fitting for the hose to pass through. The second fitting is arranged in front of the first fitting.

[0014] Preferably, the gun holder body includes a rear base, on which a handle is fixed, and a return spring is disposed inside the rear base. The gun holder body also includes a first connector disposed between the rear base and the first feeding assembly, and a second connector disposed between the first feeding assembly and the second feeding assembly.

[0015] Preferably, the front end of the rear base, the first sleeve connector and both ends, and the front end of the second sleeve connector are all screwed with plugs. The hose passes through all the plugs. In the loosened state, the inner wall of the plug at the rear end of the first sleeve connector isolates the connection between the first input pipeline and the inlet hole.

[0016] Preferably, the tubing is provided with a flow channel for the foamed adhesive to flow, and the flow channel extends forward and backward from the inlet hole.

[0017] Preferably, under pressure, the expanding foam sprayed from the front end of the dispensing line and the drying agent sprayed from the front end of the output channel are mixed outside the glue gun.

[0018] More preferably, the outer wall of the hose is provided with a step for engaging with the wrench.

[0019] Compared with the prior art, this utility model has the following beneficial effects:

[0020] 1. Installation is more convenient. Simply install the expanding foam canister at the first installation port and the drying agent canister at the second installation port to complete the assembly.

[0021] 2. It is more convenient to use. Pressing the wrench will dispense the glue. Since the foaming glue and drying agent react outside the glue gun, the reactants will not remain in the gun head and will not cause blockage. Therefore, the gun head located at the front end of the drying agent tube does not need to be replaced frequently, resulting in low operating costs.

[0022] 3. Since the drying agent tube is attached to the front of the glue tube, it is essentially a single-tube structure, which is more compact and stable, making the glue gun assembly easier. Attached Figure Description

[0039] Detailed implementation plan: See below Figures 1-10 This utility model is a simple two-component glue gun, comprising:

[0040] The gun holder body 100 is equipped with a first feeding assembly 120 and a second feeding assembly 130. The first feeding assembly 120 is provided with a first input pipe 122, and the second feeding assembly 130 is provided with a second input pipe 132.

[0041] A hose 200 is installed on the gun holder body 100 and passes through the first feeding assembly 120. The hose 200 extends in the front-back direction and has an inlet hole 230.

[0042] The drying agent tube 500 is mounted on the second feeding assembly 130 at its rear end and extends in the front-to-back direction. The drying agent tube 500 is sleeved on the front of the rubber tube 200 and cooperates with the rubber tube 200 to form a flow channel 510. The second input pipe 132 is connected to the flow channel 510. The front end of the drying agent tube 500 is provided with a gun head 520. The rubber tube 200 passes through the gun head 520. An output channel 530 is provided between the gun head 520 and the outer wall of the rubber tube 200. An opening and closing structure is provided between the gun head 520 and the rubber tube 200 to adjust whether the flow channel 510 and the output channel 530 are connected.

[0043] The wrench 300 is hinged to the gun body 100 and has a loose state and a press state. In the loose state, the first input pipe 122 and the inlet hole 230 are disconnected and the opening and closing structure is closed. In the press state, the wrench 300 drives the rubber tube 200 to move backward relative to the drying agent tube 500, the first input pipe 122 and the inlet hole 230 are connected, the opening and closing structure is opened, the foaming adhesive in the first input pipe 122 enters the rubber tube 200 through the inlet hole 230, and the drying agent in the guide channel 510 enters the output channel 530.

[0044] The return spring 400 is disposed in the gun holder body 100 and abuts against the rear end of the hose 200.

[0045] As a preferred embodiment of this example, the opening and closing structure includes a wedge-shaped surface 240 disposed on the outer wall of the tubing 200 and a guide slope 521 disposed at the rear end of the gun head 520, with a closing point 522 formed between the front end of the guide slope 521 and the rear end of the output channel 530.

[0046] See Figure 4 , Figure 7 As can be seen, in the released state, the closing point 522 abuts against the wedge-shaped surface 240, isolating the flow channel 510 and the output channel 530; see reference Figure 8 and Figure 10 As can be seen, when pressed, the closing point 522 moves away from the wedge surface 240, and the flow channel 510 and the output channel 530 are connected.

[0047] Working principle of opening and closing structure: see Figure 4 and Figure 7 As can be seen, the extending direction of the guide ramp 521 and the extending direction of the output channel 530 form an angle with each other, forming a closure point 522 at the bend. In the released state, this closure point 522 abuts against the wedge-shaped surface 240, thereby separating the guide channel 510 and the output channel 530. (See reference...) Figure 8 and Figure 10 When the tubing 200 moves backward, the wedge surface 240 also moves backward. Since the position of the gun head 520 remains unchanged, the sealing point 522 leaves the wedge surface 240, and the flow channel 510 and the output channel 530 are connected. The drying agent located in the flow channel 510 will enter the output channel 530.

[0048] Then, please see Figures 1-4As can be seen, the upper end of the first feeding assembly 120 is provided with a first installation port 121 that is connected to the foam adhesive tank. The first feeding assembly 120 also includes a first sleeve 123 through which the adhesive tube 200 passes. The first input pipe 122 is located between the first installation port 121 and the first sleeve 123. In the loosened state, the inner wall of the first sleeve 123 isolates the connection between the first input pipe 122 and the inlet hole 230.

[0049] Next, in this embodiment, the upper end of the second feeding assembly 130 is provided with a second mounting port 131 that is connected to the drying agent tank. The second feeding assembly 130 also includes a second connector 133 through which the glue tube 200 passes. The second connector 133 is arranged in front of the first connector 123. The second input pipe 132 is arranged between the second mounting port 131 and the second connector 133. The rear end of the drying agent tube 500 extends into and is fixed inside the second connector 133.

[0050] Furthermore, in this embodiment, the gun holder body 100 includes a rear base 110, on which a handle 140 is fixed, and a return spring 400 is disposed inside the rear base 110. The gun holder body 100 also includes a first connector 150 disposed between the rear base 110 and the first feeding assembly 120, and a second connector 160 disposed between the first feeding assembly 120 and the second feeding assembly 130.

[0051] Here, the gun base body 100 is a one-piece molded design, and the rear base 110, the first feeding assembly 120, the second feeding assembly 130, the handle 140, the first connector 150 and the second connector 160 do not need to be assembled separately, making the structure more stable.

[0052] Then, please see Figure 4 and 5 As can be seen, the wrench 300 is hinged to the first connector 150, and the outer wall of the hose 200 is provided with a step 220 for engaging and abutting the wrench 300.

[0053] In this embodiment, when the wrench 300 is pulled backward by hand, the wrench 300 will rotate clockwise around the hinge point on the first connector 150 and press the step 220 on the hose 200 backward, thereby driving the hose 200 to move backward.

[0054] Next, please refer to Figure 4 , Figure 6 , Figure 8 and Figure 9As can be seen, in this embodiment, the front end of the rear base 110, the first set of connectors 123 and both ends, and the front end of the second set of connectors 133 are all screwed with plugs. The hose 200 passes through all the plugs. In the loosened state, the inner wall of the plug located at the rear end of the first set of connectors 123 isolates the connection between the first input pipe 122 and the inlet hole 230.

[0055] The above text has already described the working principle of controlling the backward translation of the hose 200 by turning the wrench 300, and the working principle that the opening and closing structure is opened during the backward translation of the hose 200, and the drying agent located in the flow channel 510 will enter the output channel 530.

[0056] Please see Figure 4 and Figure 5 As can be seen, in this embodiment, the tube 200 is provided with a flow channel 210 for the flow of foamed adhesive, and the flow channel 210 extends forward and backward from the inlet hole 230.

[0057] The dispensing principle of the 200 hose is explained below:

[0058] See Figure 4 , Figure 6 As can be seen, in this embodiment, there are two inlet holes 230, respectively located on the upper and lower sides of the tube 200. By providing plugs at both ends of the first connector 123, and with the tube 200 passing through the plugs, a gap is created between the outer wall of the tube 200 and the internal channel of the first connector 123. The expanding foam flowing from the first input pipe 122 will continue to fill this gap. When the wrench 300 is in the released state, the inlet holes 230 are sealed by the plugs, and the expanding foam in the gap cannot enter the tube 200. When the wrench 300 is in the pressed state, as described above, the tube 200 will move backward, at which point both inlet holes 230 are connected to the gap, and the expanding foam in the gap will enter the glue flow pipe 210 in the tube 200.

[0059] More specifically, under pressure, the expanding foam sprayed from the front end of the self-flowing adhesive tube 210 and the drying agent sprayed from the front end of the self-output channel 530 are mixed on the outside of the glue gun.

[0060] Note that in this embodiment, the internal pressure of the expanding foam in the gap and the drying agent in the flow channel 510 is very high. When the wrench 300 is in the pressing state, the expanding foam in the gap will be instantly impacted into the glue flow line 210, and the drying agent in the flow channel will be instantly impacted into the output channel 530. They will then be sprayed out from the front of the gun head 520 almost without any distinction between front and back. When the expanding foam and the drying agent are sprayed forward at the same time, they will undergo a chemical reaction on the outside of the glue gun, which will accelerate the curing of the expanding foam.

[0061] The above description of a simplified two-component glue gun of this utility model is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
