Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a portable single-tube glue gun. Background Art

[0002] A glue gun is a tool for applying glue (or extruding glue), which is widely used in industries such as architectural decoration, electronic appliances, automobiles and auto parts, ships and containers. Existing single-component glue guns generally install the glue tank on the glue gun through fixed buckles, involving the installation of multiple parts, and the operation is relatively complex during assembly. Moreover, currently, when applying glue, the glue outlet pipe is generally directly installed at the front end of the glue tank for applying glue. After the glue application is completed, the residual glue in the glue tank will remain at the glue outlet pipe, and after standing for a period of time, it will cause the glue outlet of the glue tank to adhere to the glue outlet pipe, and only a new glue tank can be replaced for glue application, wasting the remaining glue components in the glue tank.

[0003] Chinese Patent CN207974475U discloses a polyurethane foam sealant foaming glue gun for a pressure tank. One end of the pressure tank is provided with a threaded ring and a discharge port. Among them, the polyurethane foam sealant foaming glue gun includes a gun seat and a spray pipe; the gun seat is connected to the threaded ring; the spray pipe is detachably inserted into the gun seat and connected to the discharge port; so that the polyurethane foam sealant foaming glue gun is connected to the pressure tank. The polyurethane foam sealant foaming glue gun provided by the embodiment of the utility model, because the gun seat can be connected to the threaded ring, the spray pipe is detachably inserted into the gun seat and connected to the discharge port, so that the polyurethane foam sealant foaming glue gun is connected to the pressure tank. Thus, the polyurethane foam sealant foaming glue gun is installed on the pressure tank. At the same time, the spray pipe and the gun seat are detachably connected. Therefore, when the spray pipe is blocked or damaged, the spray pipe can be directly replaced without replacing the gun seat, saving the use cost, with convenient operation and increased work efficiency.

[0004] However, when this utility model is actually used, the flow rate of the polyurethane foam sealant cannot be controlled, and it can only flow in the spray pipe at a single speed, and the flow rate of the polyurethane foam sealant cannot be adjusted in real time to meet the glue application requirements of different occasions. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a portable single-tube glue gun, which can simplify the installation method of the glue tank and the glue gun, avoid the waste of the remaining components in the glue tank caused by the glue curing and blocking the glue outlet of the glue tank, and at the same time can control the flow rate of the glue discharged from the glue tank to meet the glue application flow rate requirements of different occasions.

[0006] To solve the above technical problems, the technical solutions adopted by the utility model are as follows.

[0007] Portable single-tube glue gun, comprising a gun body, one end of the gun body is provided with an inclined handle; the other end of the gun body is hinged with a pressing handle for controlling glue output after pressing, and the side surface of the pressing handle is arc-shaped; an L-shaped glue inlet pipe is arranged through the inside of the pressing handle; the top end of the handle is provided with a glue tank mounting seat for mounting a glue tank; a speed regulating assembly which is slidably arranged on the handle and is assembled with the pressing handle to form a pressing support point and regulate the flow rate is provided on the handle.

[0008] For the above-mentioned portable single-tube glue gun, a lengthening glue pipe is threadedly mounted on the outlet side of the glue inlet pipe, and a replaceable glue outlet pipe is inserted at the end of the lengthening glue pipe.

[0009] For the above-mentioned portable single-tube glue gun, the horizontal part of the L-shaped glue inlet pipe is horizontally opened at the upper part of the pressing handle, and the outer end of the horizontal part is threadedly connected with the lengthening glue pipe; the vertical part of the L-shaped glue inlet pipe passes upward through the center of the glue tank mounting seat.

[0010] For the above-mentioned portable single-tube glue gun, the speed regulating assembly comprises a slide rail arranged on the handle, a slider is slidably arranged on the slide rail, and an arc-shaped support column which is assembled with one side of the pressing handle for support is arranged on the slider.

[0011] Due to the adoption of the above technical solutions, the technical progress obtained by the present utility model is as follows.

[0012] The present utility model provides a portable single-tube glue gun, which has a simple structure and is convenient to operate. The internal structure is simplified by integrally forming the pressing handle and the glue inlet pipe, which is convenient to carry. By threadedly mounting the glue tank vertically on the gun body and connecting the lengthening glue pipe and the glue outlet pipe in combination with the glue gun, the problem that the remaining components in the glue tank cannot be used continuously due to the solidification of the glue after glue application is solved. At the same time, by arranging a slider assembled with the pressing handle, the problem of unstable pressing of the pressing handle is solved. At the same time, the speed of glue output from the glue tank is adjusted by the movement of the slider, which can meet the glue application flow rate requirements in different occasions and improve the glue output efficiency and construction efficiency.

[0015] Wherein: 1. Gun body, 2. Handle, 3. Glue inlet pipe, 4. Lengthening glue pipe, 5. Glue outlet pipe, 6. Pressing handle, 7. Slide rail, 8. Slider, 9. Support column, 10. Glue tank mounting seat. Detailed Description of the Invention

[0016] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0017] A portable single-tube glue gun, such as Figures 1 to 2 shown, includes a gun body 1. One end of the gun body 1 is provided with an inclined handle 2. The top of the handle 2 is provided with a glue tank mounting seat 10 for mounting a glue tank. The other end of the gun body 1 is hinged with a pressing handle 6. An L-shaped glue inlet pipe 3 is penetrated through the inside of the pressing handle 6.

[0018] The horizontal part of the L-shaped glue inlet pipe 3 is horizontally opened on the upper part of the pressing handle 6. The horizontal end of the L-shaped glue inlet pipe 3 is threadedly connected with an extended glue pipe 4. The vertical part of the L-shaped glue inlet pipe 3 upwardly penetrates through the center of the glue tank mounting seat 10.

[0019] The end of the extended glue pipe 4 is inserted with a glue outlet pipe 5. The glue outlet pipe 5 is convenient to replace, avoiding that after the glue gun is used up, the glue remaining at the glue outlet pipe will solidify and block the glue outlet of the glue gun, resulting in the inoperability of the glue gun. At the same time, the glue gun is set to be detachably connected. When using it again, only the glue outlet pipe needs to be directly replaced, realizing the reuse of the glue gun.

[0020] A speed regulation assembly is slidably arranged on the handle 2 and is assembled with the pressing handle 6. The speed regulation assembly includes a slide rail 7 arranged on the handle 2. A slider 8 is slidably arranged on the slide rail 7. An arc-shaped support column 9 is arranged on the slider 8 and is assembled with one side support of the pressing handle 6.

[0021] When the slider 8 slides to the position where the support column 9 contacts the upper side surface of the pressing handle 6, pressing down the pressing handle 6, the support column 9 supports at the groove to form a fulcrum, which can ensure the stability of pressing out glue.

[0022] Since the side surface of the pressing handle 6 is arc-shaped, when the support column 9 on the slider 8 contacts different positions on the side surface of the pressing handle 6, the flow rate of the glue components in the glue tank is also different. If it is necessary to increase the flow rate of the glue components, slide the slider 8 to the upper part of the slide rail 7. At this time, the movable distance of the pressing handle is reduced and the flow rate increases; on the contrary, when the slider 8 slides to the lower part of the slide rail 7, at this time, the movable distance of the pressing handle increases and the flow rate decreases.

[0023] Since the L-shaped glue inlet pipe 3 is integrally formed with the pressing handle 6, when pressing down the pressing handle 6, the vertical part of the L-shaped glue inlet pipe 3 will jack up upward and at the same time contact the upper glue tank to open the glue tank to start feeding glue.

[0024] The using method of the present utility model is as follows:

[0025] First, threadedly install the glue tank on the glue tank mounting seat 10, and sequentially install the extended glue pipe 4 and the glue outlet pipe 5.

[0026] Then, slide the slider 8 along the slide rail 7 until the support column 9 is assembled with the groove on the pressing handle 6 and then stop.

[0027] Next, press the pressing handle 6. Under the support of the pillar 9, the vertical part of the L-shaped glue inlet pipe 3 will be lifted upward and the glue tank will be opened along with the movement of the pressing handle, and the glue feeding will start.

[0028] Finally, after stopping the glue feeding, move the slider 8 to other positions to avoid accidental touch operations.

[0029] The utility model provides a portable single-tube glue gun, which has a simple structure and is convenient to operate. By integrally molding the pressing handle and the glue inlet pipe, the internal structure is simplified and it is convenient to carry. By vertically threadedly installing the glue tank on the gun body, and connecting the glue gun through a combination of a lengthened glue pipe and a glue outlet pipe, the problem that the remaining components in the glue tank cannot be used continuously due to the solidification of the glue after caulking is solved. At the same time, by setting a slider fitted with the pressing handle, the problem of unstable pressing of the pressing handle is solved. At the same time, the glue outlet speed of the glue tank is adjusted by moving the slider, which can meet the glue outlet flow rate requirements of different occasions, and improves the glue outlet efficiency and construction efficiency.
