Description

Technical Field

[0001] This invention relates to the field of adapter technology, and more particularly to a structural adhesive fixing structure and an adapter having the structural adhesive fixing structure. Background Technology

[0002] Existing adapters for flexible structural adhesives typically require cutting off the front of the adhesive's outer shell to create an opening before installation into the glue gun body. This process is cumbersome and prone to causing adhesive leakage before it can be loaded into the glue gun body, which is quite inconvenient. Furthermore, the open adhesive is prone to leakage within the glue gun body, thus contaminating it. Summary of the Invention

[0003] In order to overcome the above-mentioned technical defects, the purpose of this invention is to provide a structural adhesive fixing structure and an adapter having the structural adhesive fixing structure, so that the structural adhesive does not need to be cut open before it is installed, and the adhesive can be dispensed directly by installing it into the adapter.

[0004] This invention discloses a structural adhesive fixing structure, which is a double-cone structure. The bottom surface of each cone is sealed, and the two cones are arranged side by side as a single unit. Structural adhesives of different components are respectively placed inside the cones. Each cone has an adhesive outlet on its side near the other cone, and the bottom of the structural adhesive fixing structure also has a dual-component adhesive outlet channel. The dual-component adhesive outlet channel includes a first channel and a second channel separated axially, and the adhesive outlets of the two cones are respectively connected to the first channel and the second channel. The glue gun body of the dual-component adapter has an adhesive outlet channel, which is connected to... The two-component adhesive dispensing channel is connected; the outer shell of the structural adhesive is a soft structure; the cone is provided with piercing teeth, the tips of the piercing teeth facing the structural adhesive; when the two-component adapter is extruded, the structural adhesive is squeezed so that the piercing teeth pierce the structural adhesive, thereby the adhesive flows from the hollow base to the dispensing port, and then the adhesives of different components flow out of the dispensing channel in sequence through the dispensing port and the two-component adhesive dispensing channel; there are two or more piercing teeth, and the two or more piercing teeth are evenly arranged circumferentially; at least one piercing tooth is correspondingly located at the dispensing port.

[0005] Preferably, the piercing teeth are located on the bottom surface of the cone and are connected to the second side wall of the cone through a rib plate.

[0006] Preferably, the tip of the piercing tooth is lower than the top of the second sidewall of the cone.

[0007] Preferably, the height of the piercing tooth is more than two-thirds of the height of the second sidewall of the cone.

[0008] Preferably, the cone is provided with a piercing sleeve, the piercing sleeve includes a hollow base and a first sidewall provided on the hollow base, the outer surface of the first sidewall is in contact with the inner surface of the cone, the inner surface of the first sidewall is in contact with the outer surface of the structural adhesive, and the piercing teeth are provided on the hollow base.

[0009] Preferably, the piercing sleeve is fixedly connected to the cone cylinder via a snap-fit ​​structure.

[0010] Preferably, the hollow base is provided with a plurality of protruding posts extending axially along the wall of the cone, the bottom surface of the protruding posts contacting the bottom surface of the cone; a first protrusion is provided radially outward on the axial protruding post, a first groove is provided axially on the wall of the cone, and the first protrusion is axially inserted into the first groove, so that the piercing sleeve is fixedly connected to the cone.

[0011] Preferably, the first sidewall of the piercing sleeve is provided with a second protrusion that protrudes radially outward, and the wall of the cone is provided with a second groove that is axially inserted into the second groove, thereby achieving a fixed connection between the piercing sleeve and the cone.

[0012] Preferably, the inner surface of the first sidewall of the piercing sleeve is provided with a first sealing gasket, which covers the entire inner surface of the first sidewall to achieve a seal between the wall surface of the first sidewall of the piercing sleeve and the wall surface of the cone; the outer surface of the first sidewall of the piercing sleeve is provided with a second sealing gasket, which covers the entire outer surface of the first sidewall to achieve a seal between the wall surface of the first sidewall of the piercing sleeve and the outer shell of the structural adhesive; the thickness of the first sealing gasket is 0.5-2mm.

[0013] Preferably, the bottom of the first sidewall of the piercing sleeve is provided with an opening, which is provided corresponding to the glue outlet, so that the opening and the hollow base together form a channel for the glue to flow to the glue outlet.

[0014] The present invention also discloses an adapter, including the structural adhesive fixing structure as described above.

[0015] Compared with existing technologies, the above technical solution has the following advantages: By setting the double-cone structure, the two-component adhesive can be mixed and dispensed. By setting piercing teeth inside the cone, the structural adhesive can be directly loaded into the glue gun body without cutting it before installation. During use, the structural adhesive will be squeezed during the normal dispensing process, causing the piercing teeth to pierce the front end of the structural adhesive and dispense the adhesive. By setting the piercing sleeve, the base of the piercing sleeve is set as a hollow base, so that after the structural adhesive is pierced, the adhesive liquid flows out of the piercing sleeve through the hollow base and then flows to the adhesive outlet of the cone. By setting the tip of the piercing tooth to be lower than the top of the second sidewall of the cone, the wall of the structural adhesive is completely covered and adhered to by the second sidewall of the cone before the piercing tooth pierces the structural adhesive, thereby preventing the adhesive from leaking between the structural adhesive and the piercing sleeve after the structural adhesive is pierced. By positioning at least one of the piercing teeth at the dispensing port, the pierced opening of the structural adhesive can be aligned with the dispensing port, thus facilitating adhesive dispensing.

[0025] See appendix Figure 1-4 The present invention discloses a structural adhesive fixing structure 1 for a two-component adapter. The structural adhesive fixing structure 1 is a double cone structure for receiving two structural adhesives 10 with different adhesive components. The two cones are arranged side by side as an integral structure. The bottom surface of the cone is sealed. Here, the bottom surface of the cone should be understood as the head corresponding to the contact with the structural adhesive 10. The structural adhesives 10 with different adhesive components are respectively placed in the two cones.

[0026] One installation method, see appendix. Figure 5-6 The adapter includes a glue gun body 8 and a glue holder 9. The glue holder 9 is used to hold structural glue 10. A structural glue fixing structure 1 is set at the head of the structural glue 10 (that is, near the outlet of the adapter) to support the head of the structural glue 10.

[0027] In addition to its supporting function, the structural adhesive fixing structure 1 also assists in mixing the two-component adhesive. Specifically, each cone has an adhesive outlet 2 on its side near the other cone; that is, the right side of the left cone has an adhesive outlet 2, and the left side of the right cone has an adhesive outlet 2. The bottom of the structural adhesive fixing structure 1 also has a two-component adhesive outlet channel 3, which can be understood as a short pipe. The two-component adhesive outlet channel 3 includes an axially separated first channel 301 and a second channel 302. The adhesive outlets 2 of the two cones extend from the sides to the bottom and connect to the first channel 301 and the second channel 302 respectively. Thus, the two-component adhesive outlet channel 3 discharges the two-component adhesive from the two cones. Next, the glue gun body 8 of the two-component adapter has an adhesive outlet channel (not shown in the attached diagram), which connects to the two-component adhesive outlet channel 3 (e.g., threaded connection), so that the two-component adhesive in the two-component adhesive outlet channel 3 is mixed after flowing out of the outlet channel.

[0028] In addition to its supporting function and the mixing function of the two-component adhesive, the structural adhesive fixing structure 1 also has the function of puncturing the structural adhesive 10. The structural adhesive 10 used with the adapter of this invention is a flexible outer shell structural adhesive 10, which can be understood as being packaged in a cylindrical bag (e.g., an aluminum bag for the outer shell). This structure is more environmentally friendly and lower in cost compared to a rigid outer shell structural adhesive 10. See appendix. Figure 7-11 This invention features a hollowed-out base inside a conical cylinder with piercing teeth 5. The tips of the piercing teeth 5 face the structural adhesive 10. During the extrusion of the two-component adapter, the conventional extrusion action will compress the structural adhesive 10, at which point the piercing teeth 5 will pierce the structural adhesive 10, allowing the adhesive to flow out. Specifically, the different components of the adhesive flow sequentially through the outlet 2 and the two-component dispensing channel 3, exiting from the dispensing channel.

[0029] A preferred embodiment is shown in the appendix. Figure 7-8 The piercing teeth of the present invention are located on the bottom surface of the cone and are connected to the second side wall of the cone through the stiffening plate 11. This is an integral structure of the piercing teeth and the cone.

[0030] Another preferred embodiment is shown in the appendix. Figure 9-11 This invention incorporates a piercing sleeve 4 within a conical cylinder. The piercing sleeve 4 includes a perforated base and a first sidewall mounted on the perforated base. The perforated base facilitates the flow of adhesive liquid from the structural adhesive 10 through the piercing sleeve 4 after piercing, leading to the outlet 2 of the conical cylinder. The outer surface of the first sidewall of the piercing sleeve 4 is in contact with the inner surface of the conical cylinder, and the inner surface of the first sidewall is in contact with the outer surface of the structural adhesive 10. The perforated base is provided with piercing teeth 5, with the tips of the piercing teeth 5 facing the structural adhesive 10. During the extrusion of the two-component adapter, the conventional extrusion action will compress the structural adhesive 10. At this time, the piercing teeth 5 will pierce the structural adhesive 10, causing the adhesive liquid to flow out. Because the outer surface of the first sidewall of the piercing sleeve 4 is in contact with the inner surface of the conical cylinder, and the inner surface of the first sidewall is in contact with the outer surface of the structural adhesive 10, the flowing adhesive liquid can only flow to the outlet 2, thus achieving smooth adhesive dispensing. This is a separate structure of the piercing teeth and the conical cylinder.

[0031] This invention enables the mixing and dispensing of two-component adhesives by setting a double-cone structure. By setting piercing teeth 5 inside the cone, the structural adhesive 10 can be directly loaded into the glue gun body without cutting it before installation. During use, the structural adhesive 10 is squeezed during the normal glue dispensing process, causing the piercing teeth 5 to pierce the front end of the structural adhesive 10, thus dispensing the adhesive.

[0032] Furthermore, there are two or more puncture teeth 5, and the two or more puncture teeth 5 are evenly arranged circumferentially to apply force evenly to the structural adhesive 10. At least one puncture tooth 5 is correspondingly set at the adhesive outlet 2, so that the puncture opening of the structural adhesive 10 is aligned with the adhesive outlet 2, thereby facilitating adhesive dispensing.

[0033] In one preferred embodiment, the number of piercing teeth 5 is three (see appendix). Figure 9 (It can also be four (see appendix)) Figure 10 ), five (see appendix) Figure 11 (e.g., etc., are not restricted here.)

[0034] In a preferred embodiment, the tip of the piercing tooth 5 is lower than the top of the second sidewall of the cone, so that before the piercing tooth 5 pierces the structural adhesive 10, the wall surface of the structural adhesive 10 is completely covered and adhered to by the second sidewall of the cone, thereby preventing the adhesive from leaking between the structural adhesive 10 and the cone 4 after the structural adhesive 10 is pierced.

[0035] Furthermore, since a piercing tooth 5 that is too short will make the process of piercing the structural adhesive 10 more difficult, or even impossible, the piercing tooth 5 should not be set too short. Preferably, the height of the piercing tooth 5 is more than two-thirds of the height of the first side wall of the piercing sleeve 4.

[0036] Preferably, when the puncture sleeve 4 and the cone are separate parts, the puncture sleeve 4 is fixedly connected to the cone through a snap-fit ​​structure.

[0037] The following provides two specific schemes for fixing the piercing sleeve 4 to the cone cylinder through a snap-fit ​​structure. It should be noted that the two schemes can be used alone or in combination. That is, only scheme one can be set, only scheme two can be set, or both scheme one and scheme two can be set at the same time.

[0038] Option 1: The hollow base has several protruding pillars 6 extending axially along the wall of the conical cylinder (see appendix). Figure 9 (There are 3 protruding pillars 6). The bottom surface of the protruding pillar 6 is in contact with the bottom surface of the cone. The protruding pillar 6 can be understood as a support. On the one hand, it supports the piercing sleeve 4 on the bottom surface of the cone. On the other hand, the support separates the hollow bottom surface of the piercing sleeve 4 from the bottom surface of the cone by a distance, thus forming a space. This space connects the glue outlet 2 of the cone and the hollow bottom surface of the piercing sleeve 4. Therefore, it is easier for the adhesive liquid of the structural adhesive 10 to flow from the hollow bottom surface of the piercing sleeve 4 to the glue outlet 2 of the cone.

[0039] Based on this, a first protrusion is radially protruding outward on the axial protrusion 6, and a first groove is axially provided on the wall surface of the cone. The first protrusion is axially inserted into the first groove, thereby making the piercing sleeve 4 and the cone fixedly connected. This fixed connection includes restricting the circumferential rotation between the piercing sleeve 4 and the cone, as well as the axial displacement of the piercing sleeve 4 in the direction away from the structural adhesive 10.

[0040] Option 2: A second protrusion is provided radially outward on the first side wall of the piercing sleeve 4, and an axial protrusion is provided on the wall of the cone (see appendix). Figure 3 The second groove 7 and the second protrusion are axially inserted into the second groove 7, thereby making the piercing sleeve 4 and the cone fixedly connected. The fixed connection also includes restricting the circumferential rotation between the piercing sleeve 4 and the cone, as well as the axial displacement of the piercing sleeve 4 away from the structural adhesive 10.

[0041] Optionally, a first sealing gasket is provided on the inner surface of the first sidewall of the piercing sleeve 4, covering the entire inner surface of the first sidewall to achieve a seal between the wall surface of the first sidewall of the piercing sleeve 4 and the wall surface of the cone. A second sealing gasket is also provided on the outer surface of the first sidewall of the piercing sleeve 4, covering the entire outer surface of the first sidewall to achieve a seal between the wall surface of the first sidewall of the piercing sleeve 4 and the outer shell of the structural adhesive 10. The first and second sealing gaskets completely block the path of adhesive backflow, ensuring that the adhesive can only flow from the perforated base to the outlet 2.

[0042] Since an excessively thick first sealing gasket would make the installation of the sleeve 4 more difficult, the thickness of the first sealing gasket is preferably set to 0.5-2mm.

[0043] Alternatively, the bottom of the first side wall of the pierced sleeve 4 is provided with an opening, which corresponds to the glue outlet 2. This allows the opening and the hollow base to form a channel for the glue to flow to the glue outlet 2. Compared to the solution without an opening, the opening provides a larger channel for the glue to flow to the glue outlet 2, which is more conducive to the glue flowing out.

[0044] The present invention also discloses an adapter, including the structural adhesive fixing structure as described above.

[0045] It should be noted that the embodiments of the present invention have better implementability and are not intended to limit the present invention in any way. Any person skilled in the art may use the above-disclosed technical content to change or modify it into equivalent effective embodiments. However, any modifications or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
