Description

Technical Field

[0001] The invention relates to the technical field of glue guns, in particular to a glue-spraying auxiliary tool. Background Art

[0002] Foaming agent is used in production and life, and is a commonly used material. For ease of use, the foaming agent is canned in a tank and used through a foaming gun or a disposable hose.

[0003] Foaming agents, such as polyurethane foam, are typically available in tube and gun versions. Tube versions typically require a disposable hose or connection to a foam gun (also known as a foam gun). Polyurethane foam is a specialized polyurethane product containing a polyurethane prepolymer, a foaming agent, a catalyst, and other components in a pressure-resistant aerosol can. It is commonly used for caulking, bonding, leak-proofing, insulation, soundproofing, and waterproofing in door and window installations. The aforementioned polyurethane foam is a typical and widely used foaming agent.

[0004] Since the valve of the tank needs to be opened when in use, and there is pressure in the tank, a foaming gun or a disposable hose is needed. However, these two types of hoses have their own shortcomings. The foaming gun is very expensive and prone to clogging. The tank must also be provided with a connection part for connecting the foaming gun, which is commonly a threaded part, which leads to an increase in the cost of the tank. Although the cost of the disposable hose is much lower than that of the foaming gun, it is necessary to hold the tank by hand and use the strength of the fingers to press the slender handle on the disposable hose to open the valve of the tank. It is very inconvenient and very strenuous to use. In addition, the pressing direction is not easy to control and the operation is prone to failure, which seriously restricts the expansion of users and the guarantee of quality of use. The disposable hose is not suitable for users with little strength or small hands. Since the disposable hose needs to be controlled well, it is greatly restricted when adjusting the direction and distance of the nozzle of the disposable hose. Unless the user is experienced and strong, it is very difficult to operate and the quality of use is low.

[0005] To this end, different from foaming guns, three types of glue auxiliary tools are proposed in the prior art: The first category is a tubular foaming gun as disclosed in the authorization announcement number CN205868626U, which includes a glue discharge pipe and an upper wrench and a lower wrench. The glue discharge pipe is directly fixed or detachably fixed or hinged to the upper wrench (that is, the glue discharge pipe is integrated on the upper wrench), and the lower wrench has a bayonet for clamping and fixing it on the tubular foaming rubber bottle. The two ends of the upper wrench respectively have a connecting part 1 and a gripping part 1, and the two ends of the lower wrench respectively have a connecting part 2 and a gripping part 2. The connecting part 1 and the connecting part 2 are connected to form a contact point 1. The upper wrench and the lower wrench rotate around the contact point 1 to make the positions of the gripping part 1 and the gripping part 2 correspond to each other and can also make the glue discharge pipe and the bayonet position correspond to each other.

[0006] The second category is a manual nozzle auxiliary glue spraying device for a foam glue can, as disclosed in the authorization announcement number CN209985647U. Unlike the first category, it does not have an integrated glue hose. Its structure includes an adjustable clamp and a trigger device. The adjustable clamp includes a clamp body and a lock structure. The lock structure is used to control the opening and closing of the adjustable clamp. The trigger device includes a trigger frame, a trigger, and a trigger clamping frame. The trigger frame is installed on the outside of the adjustable clamp and extends to the hollow end of the adjustable clamp to the central axis position. The trigger frame is inwardly curved and is used to fit the head surface of the foam glue can. The trigger clamping frame is rotatably connected to the middle of the extended end of the trigger frame. A trigger is installed below the trigger clamping frame. The trigger clamping frame is clamped on the head of the manual nozzle. This solves the problem that the foam glue can of the prior art is easy to clog using a mechanical foam glue gun and is laborious and difficult to control using a manual nozzle.

[0007] The third category is a gluing auxiliary tool previously proposed by the inventor of this application, such as a foaming gun disclosed in the authorization announcement number CN216025659U. It is different from the first and second categories, and it does not have an integrated hose, but still uses the original disposable hose. Specifically, the structure includes a fixing part, which is used to detachably install and fix the tank body of the foaming agent. A handle is provided on the rear side of the fixing part, and an operating handle is provided on the lower side of the fixing part. The operating handle is hinged to the front part of the fixing part. When the tank body is installed and fixed on the fixing part, the valve of the tank body is located on the upper side of the operating handle, and the outlet of the hose of the tank body is located on the lower side of the operating handle. The operating handle can be swung upward through the hinge to open the valve. When the user's hand applies force, the rationality of the force transmission is high, which can make the user operate more easily.

[0008] From the above, it can be seen that although the existing gluing auxiliary tools have made great progress, are convenient to use and reduce costs, they still require two main structures: the structure of the handle on the disposable hose or the valve at the lower end of the tank body, and the operating handle structure. The first type also needs to integrate the hose, so it is more complicated and inconvenient to use than the second and third types.

[0009] To this end, the applicant conducted further research and first proposed a new gluing auxiliary tool. The gluing auxiliary tool can still use the existing disposable hose, but there is no need to additionally set a handle structure and an operating handle structure on the disposable hose (such as the upper wrench design in the first category, the trigger device design in the second category, and the operating handle design in the third category). For details, please refer to the prior patent application number 202520055851X for a gluing auxiliary tool. The entire content of the prior patent application is incorporated into this application.

[0010] Although compared with the existing technology, the new gluing auxiliary tool has greatly simplified the structure and is also convenient for users to control the direction of glue spraying, it is inconvenient for users with shorter fingers. Therefore, the applicant will further optimize it to improve the controllability of glue spraying and ease of use while also making it easier for users with shorter fingers to use. Summary of the Invention

[0011] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a gluing auxiliary tool that improves the controllability of glue spraying and ease of use while also being convenient for users with shorter fingers.

[0012] Compared with the existing technology, the present invention proposes a gluing auxiliary tool, including a tank body fixing ring and a handle, one end of the handle is connected to the tank body fixing ring so that the handle is supported by the tank body fixing ring and suspended on one side. When the tank body fixing ring is fixed to the end where the valve of the tank body is located, the handle is located on the rear side of the hose connected to the valve, and the handle is tilted toward the handle side of the hose. In addition, the tank body fixing ring is provided with a support portion, which is used to support the front of the handle.

[0013] When the user holds the handle, the base of the hand is close to the side of the tank body, and the handle is held in the user's hand. The fingers on the handle side close to the hose can extend forward to the rear of the handle and pull the rear of the handle. The support part cooperates to support the front of the handle when the fingers pull the rear of the handle.

[0014] After adopting the above structure, compared with the prior art, the present invention has the following advantages: It should be noted that the present invention is a gluing auxiliary tool, and the tank body connected to the hose mentioned is a consumable, and is not a component of the gluing auxiliary tool itself, just like the relationship between a gun and a bullet, the bullet is a consumable.

[0015] The preferred method of use of the present invention is to first connect a hose (such as a disposable hose) to the tank body, and then fit the valve end of the tank body with the tank body fixing ring of the present invention to fix it. The fixation brings two position states. The first is that the handle is located on the rear side of the hose connected to the valve, and the handle is tilted toward the handle side of the hose. The second is that the front part of the handle of the hose is supported by the support part. In this way, when the user's hand holds the handle, the base of the hand is close to the side of the tank body, and the handle is held in the user's hand. The fingers on the handle side of the hose can extend forward to the rear part of the handle and pull the rear part of the handle. The support part cooperates to support the front part of the handle when the fingers pull the rear part of the handle, thereby bringing several technical advantages, namely: 1) Since the hose is Generally, the tube is made of plastic molding and does not have very high strength. Therefore, when the finger pulls the handle, the tube is prone to swing back and forth and deviate from the axial movement, resulting in difficulty in control, poor valve opening and control accuracy after opening. However, since the support part of the present invention cooperates with the front part of the support handle when the finger pulls the rear part of the handle, it is beneficial to greatly reduce the back and forth swing and facilitate axial movement. When using, the user can open the valve to discharge glue by slightly pulling the rear part of the handle with his finger, making operation easy. In addition, since the axial movement is guaranteed, the valve opening is also easy to estimate, making the control of the glue discharge amount more convenient, thereby improving the controllability of glue spraying. 2) The finger only needs to reach the rear part of the handle, which is convenient for users with shorter fingers.

[0016] In summary, the present invention not only improves the controllability of glue spraying and ease of use, but is also convenient for users with shorter fingers.

[0017] As can be seen from the above, the gluing auxiliary tool can still use the existing disposable hose, but there is no need to additionally set up a handle structure for pressing the disposable hose and an operating handle structure, thereby greatly simplifying the structure.

[0018] In addition, due to the design of the present invention, the hand is designed to be as close to the side of the tank body as possible, so when the user's hand holds the handle, the resistance arm formed is shorter than that in the prior art. In the prior art, when the user's hand holds the handle, it is farther away from the tank body, and the resistance arm formed is longer (this is true for the first, second and third cases). Therefore, the present invention is more labor-saving than the prior art, which is of great significance for gluing work that requires a long time. At the same time, since the base of the hand is close to the side of the tank body, the user's hand is closer to the center of gravity of the tank body, which is more conducive to the user's flexible operation.

[0019] As an improvement, the upper end of the support portion is connected to the front side of the tank body fixing ring, and the lower end of the support portion extends downward and rearward to the lower side of the tank body fixing ring.

[0020] As an improvement, the support portion is provided with an adjustable support structure at the front portion of the support handle, and the adjustable support structure is used to adjust and determine the initial position of the front portion of the support handle.

[0021] As an improvement, the adjustable support structure adopts an adjustable support plate, which is arranged along the front-to-back direction and can be connected to the support part in a swingable manner. After being adjusted into place, the adjustable support plate is fixed to determine the initial position.

[0022] As an improvement, the adjustable support structure adopts an adjusting screw, and the initial position is adjusted and determined by rotating the adjusting screw.

[0023] As an improvement, the support portion is provided with a limiting structure at the front portion of the support handle, and the limiting structure is used to limit the front portion of the support handle to the left and right to prevent the front portion from shaking left and right.

[0024] As an improvement, the limiting structure adopts a groove with an upper opening, and the front part of the handle is clamped in the groove along the up and down directions.

[0025] As an improvement, the non-closed loop of the tank body fixing ring is arranged to have a left side and a right side, and the left side and the right side are provided with a gap at the front end away from the handle, and the support part is provided with two side plates spaced apart on the left and right sides at least at the upper end connected to the tank body fixing ring, which are respectively a first side plate and a second side plate, the first side plate is connected to the left side of the tank body fixing ring, and the second side plate is connected to the right side of the tank body fixing ring, and the left side and the right side can be separated to facilitate the installation of the valve end of the tank body.

[0026] As an improvement, a locking structure is provided between the first side plate and the second side plate, which pulls the first side plate and the second side plate together so that the left and right sides clamp and fix the end of the valve of the tank body, and when unlocked, the distance between the first side plate and the second side plate becomes larger so that the left and right sides release the clamping and fixation of the end of the valve of the tank body; and / or, the left and right sides are provided with a locking structure at the said interval, which pulls the left and right sides together so that the left and right sides clamp and fix the end of the valve of the tank body, and when unlocked, the distance between the left and right sides becomes larger so that the left and right sides release the clamping and fixation of the end of the valve of the tank body.

[0027] As an improvement, an elastic connecting portion is provided between the first side plate and the second side plate, which pulls the first side plate and the second side plate together so that the left and right sides clamp and fix the end of the valve of the tank body, and when the elastic connecting portion is stretched, the distance between the first side plate and the second side plate becomes larger so that the left and right sides release the clamping and fixation of the end of the valve of the tank body; and / or, the left and right sides are provided with an elastic connecting portion at the said interval, which pulls the left and right sides together so that the left and right sides clamp and fix the end of the valve of the tank body, and when the elastic connecting portion is stretched, the distance between the left and right sides becomes larger so that the left and right sides release the clamping and fixation of the end of the valve of the tank body.

[0028] As an improvement, the elastic connecting portion is configured as an arc-shaped portion convex outward.

[0029] As an improvement, the tank body fixing ring, handle and support part are an integrated plastic structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0043] The present invention will be further described in detail below: like Figures 2 to 10 As shown, a gluing auxiliary tool is disclosed. Figure 1 Shown are the objects or consumables used by the gluing auxiliary tool. Figure 11 This is a three-dimensional schematic diagram of the first embodiment of the present disclosure after the tank body connected with the hose is installed.

[0044] The gluing auxiliary tool includes a tank body fixing ring 1 and a handle 2. One end of the handle 2 is connected to the tank body fixing ring 1 so that the handle 2 is supported by the tank body fixing ring 1 and suspended on one side. When the tank body fixing ring 1 is fixed on the end where the valve is located of the tank body 3, the handle 2 is located on the rear side of the hose 4 connected to the valve, and the handle 2 is tilted toward the handle 5 side of the hose 4. In addition, the tank body fixing ring 1 is provided with a support part 6, which is used to support the front part 7 of the handle 5.

[0045] When the user's hand holds the handle 2, the base of the hand is close to the side of the tank body 3, and the handle 2 is held in the user's hand. The fingers on the side of the handle 5 close to the hose 4 can extend forward to the rear part 8 of the handle 5 and pull 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 pull the rear part 8 of the handle 5.

[0046] In some embodiments, as Figure 2 、 3As shown in , 4 , the upper end of the support portion 6 is connected to the front side of the tank body fixing ring 1 , and the lower end of the support portion 6 extends downward and rearward to the lower side of the tank body fixing ring 1 .

[0047] In some embodiments, in particular, Figure 4 、 8 As shown, the support portion 6 is provided with an adjustable support structure at the position of the front portion 7 of the support handle 5 , and the adjustable support structure is used to adjust and determine the initial position of the front portion 7 of the support handle 5 .

[0048] 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 is in a tilted state. Then, when the finger pulls the rear part 8 of the handle 5, the part of the handle 5 connected to the valve just moves axially to open the valve. Using 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, when the rear part 8 is pulled, the forward swinging movement of the front part 7 is also suppressed to a certain extent.

[0049] Any adjustable support structure applicable to the present disclosure can be applied to the present disclosure.

[0050] like Figure 8 As shown, the adjustable support structure adopts an adjustable support plate 9, for example. The adjustable support plate 9 is arranged along the front-to-back direction and can be connected to the support part 6 in a swingable manner up and down. That is, the adjustable support plate 9 is hinged at the lower end of the support part 6. After being adjusted into place, the adjustable support plate 9 is fixed to determine the initial position.

[0051] The fixing arrangement may be a knob fixing, a snap-on fixing, etc. In this example, Figure 8 The example shown uses an abutment portion 19 provided on the lower side of the adjustable support plate 9 and an abutment end surface 20 provided on the lower end of the support portion 6 to cooperate and fix. This structure has the advantage of being easy to use, but has the disadvantage of only providing one preset position.

[0052] like Figure 4 As shown, the adjustable support structure adopts an adjusting screw 10, for example, and the initial position is adjusted by rotating the adjusting screw 10. The advantage of this structure is that it can provide multiple preset positions, thereby obtaining different degrees of upward pressure on the front part 7.

[0053] In some embodiments, in particular, Figure 3 、 8 As shown, the support portion 6 is provided with a limiting structure at the position of the front portion 7 of the support handle 5 , and the limiting structure is used to limit the front portion 7 of the support handle 5 left and right to prevent the front portion 7 from shaking left and right.

[0054] Furthermore, the limiting structure adopts a groove 11 with an upper opening, and the front portion 7 of the handle 5 is clamped in the groove 11 along the up and down direction. In this way, it is more convenient to disassemble and assemble the tank body 3.

[0055] In particular, such as Figure 8 As shown, the adjustable support plate 9 is further integrated with a groove 11 .

[0056] In some embodiments, as Figure 2 、 3 As shown, the tank body fixing collar 1 is arranged in a non-closed loop, with a left side portion 12 and a right side portion 13. The left side portion 12 and the right side portion 13 are separated at the front end away from the handle 2. The support portion 6 is provided with two side panels spaced apart from each other at least at the upper end connected to the tank body fixing collar 1. These panels are a first side panel 14 and a second side panel 15. The first side panel 14 is connected to the left side portion 12 of the tank body fixing collar 1, and the second side panel 15 is connected to the right side portion 13 of the tank body fixing collar 1. The left side portion 12 and the right side portion 13 can be separated to facilitate installation of the valve end of the tank body 3. In this way, the support portion 6 does not affect the frequent disassembly and assembly of the tank body 3 by the tank body fixing collar 1, thereby reducing the user's labor intensity.

[0057] In order to better fix the valve end of the tank body 3, as Figure 2 、 3 As shown, a locking structure 16 is provided between the first side panel 14 and the second side panel 15, and the locking structure 16 pulls the first side panel 14 and the second side panel 15 together so that the left side portion 12 and the right side portion 13 clamp and fix the end of the valve of the tank body 3. When unlocked, the distance between the first side panel 14 and the second side panel 15 becomes larger so that the left side portion 12 and the right side portion 13 release the clamping and fixation of the end of the valve of the tank body 3; and / or, the left side portion 12 and the right side portion 13 are provided with a locking structure 16 at the interval, and the 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 and fix the end of the valve of the tank body 3. When unlocked, the distance between the left side portion 12 and the right side portion 13 becomes larger so that the left side portion 12 and the right side portion 13 release the clamping and fixation of the end of the valve of the tank body 3. Any applicable locking structure 16 can be applied to the present disclosure, for example Figure 6 The swing crossbar locking technical solution shown, for example Figure 7 The technical solution of the swing arm and fisheye screw matching shown in the figure is also shown in the figure. Figure 7 The swing plastic hook locking technical solution shown.

[0058] Other structures are also possible, 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, and the elastic connecting portion 17 pulls the first side plate 14 and the second side plate 15 to each other so that the left side portion 12 and the right side portion 13 clamp and fix the end of the valve of the tank body 3. When the elastic connecting portion 17 is stretched, the distance between the first side plate 14 and the second side plate 15 becomes larger so that the left side portion 12 and the right side portion 13 release the clamping and fixation of the end of the valve 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 said interval, and the elastic connecting portion 17 pulls the left side portion 12 and the right side portion 13 to each other so that the left side portion 12 and the right side portion 13 clamp and fix the end of the valve of the tank body 3. When the elastic connecting portion 17 is stretched, the distance between the left side portion 12 and the right side portion 13 becomes larger so that the left side portion 12 and the right side portion 13 release the clamping and fixation of the end of the valve of the tank body 3.

[0059] Any applicable elastic connecting portion 17 can be applied in the present disclosure.

[0060] In particular, such as Figure 10 As shown, the elastic connecting portion 17 is configured as an arc-shaped portion 18 that bulges outward, which allows for better installation of the tank body 3 and is also more durable. In particular, the arc-shaped portion 18 has a special function, namely, it is more convenient to remove the tank body 3. Specifically, by holding the tank body 3 and pushing the arc-shaped portion 18 with the thumb, the tank body fixing ring 1 will naturally open, and at the same time, the tank body 3 is pulled so that the portion of the tank body 3 on the side of the arc-shaped portion 18 is first separated, and then the present invention and the tank body 3 are separated from each other. This operation is more in line with the need to replace the tank body 3 in actual use and is more convenient to use.

[0061] For the present disclosure, the integrated structure can be made of plastic, which is light and has a certain elasticity. At the same time, it can be formed 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 body fixing ring 1, the handle 2 and the support part 6 are an integrated plastic structure, and the elastic connecting part 17 can be further integrated into a plastic structure to avoid the need to assemble a lock structure, thereby further simplifying the structure and improving production efficiency.

[0062] When understanding the present invention, if necessary, the above structure can refer to other appended Figure 1 And understand, no further elaboration is needed here.

[0063] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
