Description

Technical Field

[0001] This utility model relates to the field of glue gun technology, specifically to a glue application 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:

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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. The first type is more complex and inconvenient to use than the second and third types because it also needs to integrate the glue tube.

[0010] To this end, the applicant has conducted further research and has proposed a new glue application aid tool. This glue application aid tool can still use existing disposable glue tubes, but it does not require additional structures for pressing the handle on the disposable glue tube or operating handle structures (such as the upper wrench design in the first category, the trigger device design in the second category, or the operating handle design in the third category). For details, please refer to the glue application aid tool of the prior patent application No. 202520055851X, the entire contents of which are incorporated into this application.

[0011] Although the new glue application tool has greatly simplified the structure compared to existing technologies and makes it easier for users to control the direction of glue spraying, it is still somewhat inconvenient for users with shorter fingers. Therefore, the applicant will further optimize it to improve the controllability and ease of use of glue spraying, while also making it easier for users with shorter fingers to use. Summary of the Invention

[0012] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose an adhesive application auxiliary tool that improves the controllability and ease of use of adhesive spraying, while also benefiting users with shorter fingers.

[0013] Compared with the prior art, this utility model proposes a glue application auxiliary tool, including a can fixing ring and a handle. One end of the handle is connected to the can fixing ring so that the handle is supported and suspended on one side by the can fixing ring. When the can fixing ring is fixed to the valve end of the can, the handle is located behind the glue tube connected to the valve. The handle is tilted towards the handle side of the glue tube. In addition, the can fixing ring is provided with a support part, which is used to support the front part of the handle.

[0014] When the user's hand grips the handle, the web of the hand is close to the side of the can, and the handle is held in the user's hand. The fingers on the handle side near the tube can extend forward to the back of the handle and turn the back of the handle. The support part cooperates to support the front of the handle when the fingers turn the back of the handle.

[0015] 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 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 bullets, where bullets are consumables.

[0016] 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 position states. The first is that 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. The second is that the front part of the handle of the rubber tube is supported by a support part. In this way, when the user's hand holds the handle, the web of the hand is close to the side of the can body, and the handle is held in the user's hand. The fingers close to the handle side of the rubber tube can extend forward to the rear part of the handle and turn the rear part of the handle. The support part cooperates to support the front part of the handle when the fingers turn the rear part of the handle, thereby bringing several technical advantages, namely: 1) Since the rubber tube is one Generally, tubes are made of plastic and do not have high strength. Therefore, when the handle is turned by the finger, the tube is prone to swinging back and forth and deviating from the axial movement, resulting in difficulty in control, poor valve opening and control accuracy after opening. However, in this disclosure, the support part cooperates with the front part of the handle when the finger turns the back part of the handle, which helps to greatly reduce the back and forth swing and facilitates axial movement. When using it, the user can open the valve and dispense glue by slightly turning the back part of the handle with the finger, making the operation easy. In addition, since the axial movement is guaranteed, the valve opening is also easy to estimate, making the glue dispensing volume control more convenient. Therefore, it helps to improve the controllability of glue spraying. 2) The finger only needs to reach the back part of the handle, which is beneficial to users with shorter fingers.

[0017] In summary, this disclosure improves the controllability and ease of use of spray adhesive, while also benefiting users with shorter fingers.

[0018] As can be seen from the above, this glue application tool can still use existing disposable glue tubes, but there is no need to set up an additional structure for pressing the handle on the disposable glue tube and an operating handle structure, which greatly simplifies the structure.

[0019] In addition, 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.

[0020] 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.

[0021] As an improvement, the support part is provided with an adjustable support structure at the front of the support handle. The adjustable support structure is used to adjust and determine the initial position of the front of the support handle.

[0022] As an improvement, the adjustable support structure adopts an adjustable support plate. The adjustable support plate is set along the front-to-back direction and can be connected to the support part in a swinging manner. After adjustment, the adjustable support plate is fixed to determine the initial position.

[0023] As an improvement, the adjustable support structure uses an adjusting screw, which is rotated to adjust and determine the initial position.

[0024] As an improvement, the support part is provided with a limiting structure at the front of the support handle. The limiting structure is used to limit the front of the support handle to prevent the front part from swaying left and right.

[0025] As an improvement, the limiting structure adopts a groove with an opening on the upper side, and the front part of the handle is engaged in the groove in the vertical direction.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] As an improvement, the elastic connection part is set as an arc-shaped part that protrudes outward.

[0030] As an improvement, the can body fixing ring, handle and support are integrated into a single plastic structure. Attached Figure Description

Detailed Implementation

[0043] 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.

[0044] The present invention will now be described in further detail:

[0045] like Figures 2 to 10 As shown, a glue application auxiliary tool is disclosed. Figure 1 The image shows the object or consumable used by this glue application tool. Figure 11 This is a perspective view of a tank with a rubber hose connected after installation, according to Embodiment 1 of this disclosure.

[0046] The glue application auxiliary tool includes a can body fixing ring 1 and a handle 2. One end of the handle 2 is connected to the can body fixing ring 1 so that the handle 2 is supported and suspended on one side by the can body fixing ring 1. When the can body fixing ring 1 is fitted and fixed to the valve end of the can body 3, the handle 2 is located on the rear side of the glue tube 4 connected to the valve. The handle 2 is tilted towards the handle 5 of the glue tube 4. In addition, the can body fixing ring 1 is provided with a support part 6, which is used to support the front part 7 of the handle 5.

[0047] 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 on the side of the handle 5 near the tube 4 can extend forward to the rear part 8 of the handle 5 and turn the rear part 8 of the handle 5. The support part 6 cooperates to support the front part 7 of the handle 5 when the fingers turn the rear part 8 of the handle 5.

[0048] In some embodiments, such as Figure 2 ,3 As shown in Figure 4, 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.

[0049] In some embodiments, particularly, such as Figure 4 , 8 As shown, the support part 6 is provided with an adjustable support structure at the front part 7 of the support handle 5. The adjustable support structure is used to adjust and determine the initial position of the front part 7 of the support handle 5.

[0050] By setting the initial position, the position of the front part 7 can be preset. That is, under the action of the adjustable support structure, the front part 7 is pressed upward and tilted up. When the finger pulls the rear part 8 of the handle 5, the part of the handle 5 connected to the valve moves axially to open the valve. With the above structure, the valve can be opened by slightly pulling the rear part 8. In addition, since the initial position is set, that is, the position of the front part 7 is preset, the forward swinging movement of the front part 7 is also suppressed to a certain extent when the rear part 8 is pulled.

[0051] Any adjustable support structure applicable to this disclosure can be used in this disclosure.

[0052] like Figure 8 As shown, the adjustable support structure may be an adjustable support plate 9, which is set along the front-to-back direction and can be connected to the support part 6 in a swinging manner. The adjustable support plate 9 is hinged to the lower end of the support part 6. After adjustment, the adjustable support plate 9 is fixed to determine the initial position.

[0053] The fixing method can be knob fixing, snap-fit ​​fixing, etc., as in this example... Figure 8 The example shown uses a mating part 19 located on the lower side of the adjustable support plate 9 and abutting end face 20 located at the lower end of the support part 6 for fixation. The advantage of this structure is that it is easy to use, but the disadvantage is that it only provides one preset position.

[0054] like Figure 4 As shown, the adjustable support structure uses, for example, an adjusting screw 10. The initial position is determined by rotating the adjusting screw 10. The advantage of this structure is that it can provide a variety of preset positions, thereby obtaining different degrees of upward pressure on the front part 7.

[0055] In some embodiments, particularly, such as Figure 3 , 8 As shown, the support part 6 has a limiting structure at the front part 7 of the support handle 5. The limiting structure is used to limit the front part 7 of the support handle 5 to the left and right to prevent the front part 7 from swaying left and right.

[0056] Furthermore, the limiting structure adopts a groove 11 with an upper opening, and the front part 7 of the handle 5 is engaged in the groove 11 in the vertical direction. This makes it easier to disassemble and assemble the tank 3.

[0057] In particular, such as Figure 8 As shown, the adjustable support plate 9 also integrates a groove 11.

[0058] In some embodiments, such as Figure 2 , 3 As 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.

[0059] To better secure the valve end of tank 3, such as Figure 2 , 3 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 6 The swing bar locking technology solution shown is, for example... Figure 7 The technical solution shown is the combination of the swing arm and the fisheye screw, for example... Figure 7 The swinging plastic hook locking technology solution shown is illustrated.

[0060] It can also be other structures, such as... Figure 5 , 10As 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.

[0061] Any suitable flexible connection 17 can be used in this disclosure.

[0062] In particular, such as Figure 10 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.

[0063] 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 , 5 As shown in Figures 9 and 10, the tank fixing ring 1, the handle 2, and the 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.

[0064] When understanding this utility model, the above structure may be referred to other appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.

[0065] 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.
