Description

Technical Field

[0001] This utility model relates to the field of glue gun technology, specifically a trigger-type glue dispensing auxiliary tool. Background Technology

[0002] Foaming agents are used in both production and daily life, and are a common type of material. For ease of use, foaming agents are packaged in cans and applied via foaming guns or disposable tubing.

[0003] The foaming agents mentioned, such as polyurethane foam, are generally divided into two types: tube type and gun type. Tube type usually comes with a disposable tube or requires connection to a foaming gun (or foam glue gun) for use. Polyurethane foam is a special polyurethane product that contains polyurethane prepolymer, foaming agent, catalyst, and other components in a pressurized aerosol can. It is commonly used for sealing gaps, bonding, leak plugging, thermal insulation, sound insulation, and waterproofing in doors and windows. The aforementioned polyurethane foam is a typical foaming agent and is widely used.

[0004] Because the use of this product requires opening the valve of the can, and the can is pressurized, a foam gun or a disposable hose is needed. However, both have their drawbacks. Foam guns are expensive, prone to clogging, and require a connection point (usually a threaded part) on the can to connect to the foam gun, further increasing the can's cost. While disposable hoses are much cheaper than foam guns, they require holding the can and using your fingers to press the thin handle on the hose to open the valve, which is inconvenient and strenuous. Furthermore, the pressing direction is difficult to control, leading to operational failures and severely limiting user expansion and ensuring product quality. Disposable hoses are unsuitable for users with little strength or small hands. The need to control the hose also greatly restricts adjustments to the nozzle direction and distance, making it difficult to operate unless the user is experienced and strong, resulting in lower quality of use.

[0005] Therefore, in contrast to foam guns, three types of glue application auxiliary tools have been proposed in existing technologies: The first type is a tubular foam gun disclosed in the authorization announcement number CN205868626U. The tubular foam gun includes a dispensing tube, an upper wrench, and a lower wrench. The dispensing tube is directly fixed, detachably fixed, or hinged to the upper wrench (i.e., the dispensing tube is integrated into the upper wrench). The lower wrench has a locking slot for locking onto the tubular foam bottle. The two ends of the upper wrench have a connecting part one and a gripping part one, respectively. The two ends of the lower wrench have a connecting part two and a gripping part two, respectively. The connecting part one and the connecting part two are connected to form an ammonium contact point one. The upper wrench and the lower wrench can rotate around the ammonium contact point one so that the positions of the gripping part one and the gripping part two correspond, and also so that the positions of the dispensing tube and the locking slot correspond.

[0006] The second type is an auxiliary spraying device for manual spraying nozzles of expanding foam cans, as disclosed in authorization announcement number CN209985647U. Unlike the first type, it does not integrate a spray tube. Its structure includes an adjustable clamp and a trigger device. The adjustable clamp includes a clamp body and a locking structure, which controls the opening and closing of the adjustable clamp. The trigger device includes a trigger frame, a trigger, and a trigger engagement frame. The trigger frame is installed on the outside of the adjustable clamp and extends towards the hollow end of the adjustable clamp to the central axis. The trigger frame is inwardly curved to fit against the curved surface of the head of the expanding foam can. The trigger engagement frame is rotatably connected to the middle of the extended end of the trigger frame. The trigger is installed below the trigger engagement frame, and the trigger engagement frame engages with the head of the manual spray nozzle. This solves the problems of easy clogging with mechanical expanding foam guns and the laborious and difficult-to-control operation of manual spraying nozzles in existing technologies.

[0007] The third type is the glue application auxiliary tool proposed by the inventor of this application, such as the foam gun disclosed in the authorization announcement number CN216025659U. It is different from the first and second types. It does not integrate the glue tube itself, but still uses the original disposable glue tube. Specifically, the structure includes a fixing part for detachably installing and fixing the foaming agent can. The rear side of the fixing part is provided with a handle, and the lower side of the fixing part is provided with an operating handle. The operating handle is hinged to the front part of the fixing part. After the can is installed and fixed in the fixing part, the valve of the can is located on the upper side of the operating handle, and the outlet of the glue tube of the can is located on the lower side of the operating handle. The operating handle can swing upward through the hinge to open the valve. When the user applies force, the force transmission is more reasonable, which makes it easier for the user to operate.

[0008] As can be seen from the above, although existing glue application tools have made great progress, making glue application more convenient and reducing costs, they still require two main structures: a handle on the disposable glue tube or a valve at the bottom of the can, and an operating handle. Furthermore, the operating handle needs to move significantly or be converted into a valve-opening motion to achieve its function. This results in the operating handle being a large moving structure that cannot be made smaller. The first type, because it also needs to integrate the glue tube, is more complex and inconvenient to use than the second and third types.

[0009] To this end, the applicant has conducted further research and proposed a new glue application aid tool. This glue application aid tool can still use existing disposable glue tubes, but it is advantageous for directly pushing the valve and making the operating handle a smaller moving structure, as well as for users with shorter fingers. Utility Model Content

[0010] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a trigger-type glue application auxiliary tool. This glue application auxiliary tool can still use the existing disposable glue tube, but it is advantageous to directly push the valve and make the moving structure of the operating handle smaller, and it is also advantageous for users with shorter fingers.

[0011] Compared with the prior art, this utility model proposes a trigger-type glue application auxiliary tool, including a can body fixing ring and a handle. One end of the handle is connected to the can body fixing ring so that the handle is supported and suspended on one side by the can body fixing ring. The can body fixing ring is provided with a support part, the lower end of which extends downward to the handle side. The lower end is hinged to a trigger. An opening is provided between the front end and the lower end of the trigger for the tube body of the glue tube connected to the can body to pass through. The trigger and the rear part of the handle are fitted together from bottom to top. The support part and / or the trigger are also provided with a left and right limiting structure that is set in the front-back direction and has an opening on the upper side, which is used to limit the left and right swing of the handle. When the can body fixing ring is fitted and fixed to the valve end of the can body connected to the glue tube, the tube body of the glue tube passes through the opening, and the handle is fitted into the left and right limiting structure from the upper opening of the left and right limiting structure and is limited. At the same time, the trigger and the rear part are fitted together from bottom to top, and the handle is located on the rear side of the glue tube, and the handle is tilted towards the handle side of the glue tube.

[0012] When the user's hand grips the handle, the web of the hand is close to the side of the canister, and the handle is held in the user's hand. The fingers can reach forward to the trigger and pull the trigger to push the rear part upward, thereby opening the valve.

[0013] After adopting the above structure, compared with the prior art, the present invention has the following advantages: It should be noted that the present disclosure is a trigger-type glue application auxiliary tool, and the can with glue tube mentioned is a consumable and not a component of the glue application auxiliary tool itself, just like the relationship between a gun and a bullet, where the bullet is a consumable.

[0014] The preferred method of use of this disclosure is as follows: First, a rubber tube (e.g., a disposable rubber tube) is connected to the can body. Then, the valve end of the can body is fitted and fixed to the can body fixing sleeve of this disclosure. This fixing results in two positional states. In the first state, the handle is located behind the rubber tube connected to the valve, and the handle is tilted towards the handle side of the rubber tube. In the second state, the tube body passes through the opening, and the trigger and the rear part are fitted together as one unit. Thus, when the user's hand grips the handle, the web of the hand is close to the can body, and the handle is held in the user's hand, with the fingers close to the handle side of the rubber tube. The valve can be opened by extending forward to the back of the handle and pulling the trigger, which brings several technical advantages: 1) The glue application tool can still use existing disposable glue tubes; 2) Since the trigger and the back are integrated, pulling the trigger will directly drive the back to open the valve, thus directly pushing the valve. The size of the trigger can be minimized, as long as it is integrated with the back and suitable for finger operation, which is conducive to making the operating handle a smaller size; 3) The fingers only need to extend to the back of the handle, which is beneficial for users with shorter fingers.

[0015] In particular, due to the design of this disclosure, the hand is positioned as close to the side of the can as possible. Therefore, the resistance arm formed when the user's hand grips the handle is shorter than that of the prior art. In the prior art, when the user's hand grips the handle, it is farther from the can, resulting in a longer resistance arm (this is true for the first, second, and third cases). Therefore, this disclosure is more labor-saving than the prior art, which is of great significance for work that requires long periods of glue application. At the same time, because the web of the hand is closer to the side of the can, the user's hand is closer to the center of gravity of the can, which also makes it easier for the user to operate flexibly.

[0016] As an improvement, the upper end of the support is connected to the front side of the tank fixing ring, and the lower end of the support extends downward and backward to the lower side of the tank fixing ring.

[0017] As an improvement, a trigger is provided with a screw that presses upward against the lower side of the rear to form the aforementioned upper-lower fit.

[0018] As an improvement, a first arc surface is provided on the top of the trigger, and a second arc surface is provided on the lower side of the rear. The first arc surface and the second arc surface are fitted together to form the lower-upper fit.

[0019] As an improvement, the left and right limiting structures adopt left and right limiting grooves.

[0020] As an improvement, an initial positioning structure is provided between the trigger and the support. The initial positioning structure includes a first abutment provided on the trigger and a second abutment provided on the support. The first abutment and the second abutment can be separated from each other when the trigger is pulled, and the trigger is positioned at its initial position when they are in contact.

[0021] As an improvement, the tank fixing ring is not closed-loop and is arranged in the form of a left side and a right side. The left side and the right side are spaced apart at the front end away from the handle. The support part is provided with two side plates spaced apart at least at the upper end connected to the tank fixing ring. These are the first side plate and the second side plate, respectively. The first side plate is connected to the left side of the tank fixing ring, and the second side plate is connected to the right side of the tank fixing ring. The left side and the right side can be separated to facilitate the installation of the valve end of the tank.

[0022] As an improvement, a locking structure is provided between the first side plate and the second side plate. This locking structure pulls the first side plate and the second side plate together so that the left and right sides clamp the valve end of the fixed tank. When unlocked, the gap between the first side plate and the second side plate increases so that the left and right sides release the clamping and fixing of the valve end of the tank. And / or, the left and right sides are provided with a locking structure at the said gap. This locking structure pulls the left and right sides together so that the left and right sides clamp the valve end of the fixed tank. When unlocked, the gap between the left and right sides increases so that the left and right sides release the clamping and fixing of the valve end of the tank.

[0023] As an improvement, an elastic connecting portion is provided between the first side plate and the second side plate. This elastic connecting portion pulls the first side plate and the second side plate together so that the left and right sides clamp the valve end of the fixed tank. When the elastic connecting portion is opened, the gap between the first side plate and the second side plate increases so that the left and right sides release the clamping and fixing of the valve end of the tank. And / or, the left and right sides are provided with an elastic connecting portion at the said gap. This elastic connecting portion pulls the left and right sides together so that the left and right sides clamp the valve end of the fixed tank. When the elastic connecting portion is opened, the gap between the left and right sides increases so that the left and right sides release the clamping and fixing of the valve end of the tank.

[0024] As an improvement, the elastic connection part is set as an arc-shaped part that protrudes outward.

[0025] As an improvement, the can body fixing ring, handle and support are integrated into a single plastic structure. Attached Figure Description

Detailed Implementation

[0035] The following description is provided to disclose the present invention and enable those skilled in the art to implement it. The embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0036] The present invention will now be described in further detail: like Figures 2 to 8 As shown, a trigger-type glue-applying auxiliary tool is disclosed. Figure 1 The image shows the objects or consumables used in this glue application tool. Figure 1The image shows a tank 3 connected to a rubber tube 4. The upper straight section of the rubber tube 4 is inserted into the valve nozzle of the tank 3. The straight section has a front part 7 and a rear part 8 distributed in a front-to-back direction. The rubber tube 4 is made of plastic in one piece, which is inexpensive.

[0037] Figure 8 This is a three-dimensional schematic diagram of another trigger-type glue-applying auxiliary tool (with a wrench-type quick-release locking structure) after being installed on a can with a glue tube connected to it.

[0038] The glue application auxiliary tool includes a can retaining ring 1 and a handle 2. One end of the handle 2 is connected to the can retaining ring 1 so that the handle 2 is supported and suspended on one side by the can retaining ring 1. The can retaining ring 1 is provided with a support part 6. The lower end of the support part 6 extends downward to one side of the handle 5. The lower end is hinged to a trigger 9 via a pivot 25. An opening 10 is provided between the front end and the lower end of the trigger 9 for the tube 23 of the glue tube 4 connected to the can 3 to pass through. The trigger 9 and the rear part 8 of the handle 5 are engaged vertically. The support part 6 and / or the trigger 9 are also provided with a front-to-back direction that engages with the handle 5. Furthermore, the upper opening is provided with a left and right limiting structure, which is used to limit the left and right swing of the handle 5. When the can body fixing ring 1 is fixedly installed on the valve end of the can body 3 connected to the hose 4, the tube body 23 of the hose 4 passes through the opening 10, and the handle 5 is limited in the left and right limiting structure by engaging with the upper opening of the left and right limiting structure. At the same time, the trigger 9 and the rear part 8 are integrated in the upper and lower parts, that is, the trigger 9 and the rear part 8 are integrated in the upper and lower parts to form a trigger-like structure. The grip 2 is located on the rear side of the hose 4, and the grip 2 is tilted towards the handle 5 side of the hose 4.

[0039] When the user's hand grips the handle 2, the web of the hand is close to the side of the can body 3, and the handle 2 is held in the user's hand. The fingers can extend forward to the trigger 9 and pull the trigger 9 to push the rear part 8 upward, thereby opening the valve.

[0040] To ensure a better integration between the trigger 9 and the rear part 8, such as... Figure 1 , 2 As shown, the top of the trigger 9 is provided with a first arc surface 21, and the lower side of the rear part 8 is provided with a second arc surface 22. The first arc surface 21 and the second arc surface 22 are fitted together to form the lower upper fit, which is beneficial to the integrity and reduces the relative movement between the trigger 9 and the rear part 8.

[0041] It can also be other structures, for example Figure 7 As shown, the trigger 9 is provided with a screw 24, which presses upward against the lower side of the rear part 8 to form the aforementioned upper-lower fit, thereby improving the integrity of the unit and reducing the relative movement between the trigger 9 and the rear part 8.

[0042] Any structure that can improve the integrity of this invention can be applied to this invention. For example, a friction structure can be provided on the first arc surface 21 to increase friction and improve the integrity. However, when removing the can 3, the trigger 9 can be easily separated from the rear part 8, which facilitates the disassembly and assembly of the can 3 with the hose 4 connected to this invention.

[0043] In this example, opening 10 can be a hole, for example... Figure 3 As shown, other structures are also possible, such as notches. Any structure that allows the tube body 23 of the tube 4 connected to the tank body 3 to pass through when the tank body fixing ring 1 is fitted and fixed to the valve end of the tank body 3 connected to the hose 4 can be applied to this disclosure.

[0044] In some embodiments, such as Figure 2 As shown, the left and right limiting structure adopts left and right limiting grooves 11, in Figure 2 As shown, both the support 6 and the trigger 9 are provided with left and right limiting grooves 11. The left and right limiting grooves 11 can also play a role in guiding the disassembly and assembly of the handle 5 and the left and right limiting grooves 11 to a certain extent.

[0045] In some embodiments, such as Figure 2 , 3 As shown, the upper end of the support part 6 is connected to the front side of the tank fixing ring 1, and the lower end of the support part 6 extends downward and backward to the lower side of the tank fixing ring 1.

[0046] In some embodiments, in order to easily and quickly assemble the trigger 9 and the rear part 8 into a single unit after installing the tank body 3, such as... Figure 2 , 4 As shown, an initial positioning structure is also provided between the trigger 9 and the support part 6. The initial positioning structure includes a first abutment part 19 provided on the trigger 9 and a second abutment part 20 provided on the support part 6. The first abutment part 19 and the second abutment part 20 can be separated from each other when the trigger 9 is pulled, and when they are in contact, they position the trigger 9 in its initial position. That is, before the trigger 9 is pulled, this positioning makes the trigger 9 and the rear part 8 fit together in a vertical and vertical fit to form a whole.

[0047] In some embodiments, such as Figure 2 , 3As shown, the tank fixing ring 1 is configured in a non-closed loop configuration with a left side portion 12 and a right side portion 13. The left side portion 12 and the right side portion 13 are spaced apart at their front ends away from the handle 2. The support portion 6 has two side plates spaced apart at least at its upper end connected to the tank fixing ring 1, namely a first side plate 14 and a second side plate 15. The first side plate 14 connects to the left side portion 12 of the tank fixing ring 1, and the second side plate 15 connects to the right side portion 13 of the tank fixing ring 1. The left side portion 12 and the right side portion 13 can be separated to facilitate the installation of the valve end of the tank 3. In this way, the support portion 6 does not interfere with the frequent disassembly and assembly of the tank 3 by the tank fixing ring 1, thereby reducing the user's workload.

[0048] To better secure the valve end of tank 3, such as Figure 4 As shown, a locking structure 16 is provided between the first side plate 14 and the second side plate 15. This locking structure 16 pulls the first side plate 14 and the second side plate 15 together so that the left side portion 12 and the right side portion 13 clamp the valve end of the fixed tank 3. When unlocked, the first side plate 14 and the second side plate 15 are spaced further apart so that the left side portion 12 and the right side portion 13 release the clamping and fixing of the valve end of the tank 3; and / or, the left side portion 12 and the right side portion 13 are provided with a locking structure 16 at the said interval. This locking structure 16 pulls the left side portion 12 and the right side portion 13 together so that the left side portion 12 and the right side portion 13 clamp the valve end of the fixed tank 3. When unlocked, the left side portion 12 and the right side portion 13 are spaced further apart so that the left side portion 12 and the right side portion 13 release the clamping and fixing of the valve end of the tank 3. Any suitable locking structure 16 can be applied in this disclosure, for example... Figure 4 The swinging plastic hook locking technology solution is shown.

[0049] It can also be other structures, such as... Figure 2 As shown, an elastic connecting portion 17 is provided between the first side plate 14 and the second side plate 15. This elastic connecting portion 17 pulls the first side plate 14 and the second side plate 15 together so that the left side portion 12 and the right side portion 13 clamp and fix the valve end of the tank body 3. When the elastic connecting portion 17 is opened, the gap between the first side plate 14 and the second side plate 15 increases so that the left side portion 12 and the right side portion 13 release the clamping and fixing of the valve end of the tank body 3. And / or, the left side portion 12 and the right side portion 13 are provided with an elastic connecting portion 17 at the aforementioned gap. This elastic connecting portion 17 pulls the left side portion 12 and the right side portion 13 together so that the left side portion 12 and the right side portion 13 clamp and fix the valve end of the tank body 3. When the elastic connecting portion 17 is opened, the gap between the left side portion 12 and the right side portion 13 increases so that the left side portion 12 and the right side portion 13 release the clamping and fixing of the valve end of the tank body 3.

[0050] Any suitable flexible connection 17 can be used in this disclosure.

[0051] In particular, such as Figure 2 As shown, the elastic connecting part 17 is configured as an outwardly protruding arc-shaped part 18, which allows for better installation of the can 3 and is also more durable. In particular, the arc-shaped part 18 has a special function: it makes disassembling the can 3 more convenient. Specifically, by holding the can 3 and pushing the arc-shaped part 18 with the thumb, the can retaining ring 1 will naturally open. At the same time, by turning the can 3, the part of the can 3 on one side of the arc-shaped part 18 will first detach, and then the present invention will be separated from the can 3. This operation is more in line with the needs of replacing the can 3 in actual use and is more convenient to use.

[0052] For the purposes of this disclosure, a one-piece structure can be made of plastic. Plastic is lightweight and has a certain degree of elasticity, and can be molded in one step, which can greatly improve production efficiency and reduce production costs, for example... Figure 2 , 4 As shown, the tank fixing ring 1, handle 2 and support part 6 are integrated plastic structures. Furthermore, the elastic connecting part 17 can be integrated plastic structures, avoiding the need for a locking structure during assembly, thereby simplifying the structure and improving production efficiency.

[0053] When understanding this utility model, the above structure may be referred to other appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0054] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
