Description

Technical Field

[0001] The invention relates to the technical field of door and window accessories, in particular to a quick splicing structure for door and window frames. Background Art

[0002] In the modern door and window manufacturing process, the connection quality of door and window frames plays a vital role in the overall performance of doors and windows. Angle brackets, as a hardware specially used to connect components intersecting at 90 degrees, have been widely used in the connection of door and window frames.

[0003] At present, the installation processes of corner brackets mainly include movable corner bracket process, corner collision process and pin glue injection process. Among them, the pin glue injection process is highly favored and widely used in the door and window manufacturing field due to its significant advantages such as stronger corner assembly, better sealing and more beautiful appearance.

[0004] In the related art, for example, Chinese patent CN210977150U discloses a glue injection corner code for doors and windows, which includes a corner code body, in which a first glue injection screw hole, a second glue injection screw hole, a flow channel and a diversion hole are provided. When injecting glue, the glue gun head is inserted into the first glue injection screw hole and begins to inject the colloid. The colloid first reaches the flow channel through the first glue injection screw hole, and then flows along the flow channel to the diversion hole. When the colloid reaches the diversion hole, a part of the colloid is diverted through the diversion hole, and the other part of the colloid continues to flow along the flow channel. Finally, the colloid reaches saturation and flows out uniformly from the second glue injection screw hole to achieve glue sealing.

[0005] However, there are also some problems in the actual installation process of the above-mentioned door and window glue injection corner brackets: in the glue injection process, in order to ensure the quality of glue injection, the operator is not only required to keep the glue gun head at a suitable angle, but also required to push the glue gun head with a certain force to ensure that the glue can be evenly and stably injected into the connection between the corner bracket and the door and window frame. This undoubtedly increases the difficulty and complexity of the glue injection operation. In addition, during the glue injection process, the operator is also required to pay attention to the flow and saturation state of the glue at all times to avoid insufficient or excessive glue injection, which further increases the tediousness of the operation and the requirements for the operator's attention. Summary of the Invention

[0006] Based on this, it is necessary to provide a quick splicing structure for door and window frames to address the problem of troublesome operation of the current corner brackets during installation.

[0007] The above purpose is achieved through the following technical solutions: A quick-joining structure for door and window frames, which is fixed to the door and window frames by a first bolt; the quick-joining structure for door and window frames comprises a main body, which is a right-angle structure; an annular liquid capsule is sleeved at the corner of the main body, the annular liquid capsule is filled with a colloid, a puncture portion is provided on the annular liquid capsule, the puncture portion is configured to be able to puncture the annular liquid capsule, and elastic sealing rings are provided at both ends of the annular liquid capsule; a support sleeve is sleeved at both ends of the main body, the support sleeve can slide along the extension direction of the main body, the end face of the support sleeve facing the corner of the main body is a first annular cone surface, and the small end of the first annular cone surface faces the annular liquid capsule, so that when the support sleeve is close to the annular liquid capsule When the body is in the state of being pressed down, the annular liquid sac can be squeezed through the first annular cone surface, the elastic sealing ring can be stretched, and the space between the two elastic sealing rings can be sealed; a plurality of pushing blocks are arranged at intervals along the circumferential direction at both ends of the body, the pushing blocks and the supporting sleeves are guided, and the pushing blocks can slide in a direction perpendicular to the extension direction of the body; a movable sleeve and a threaded tube are provided at both ends of the body, the movable sleeve and the pushing blocks are guided, and the movable sleeve can slide in the extension direction of the body; the threaded tube extends in a direction perpendicular to the extension direction of the body and can slide along its own axial direction, the threaded tube and the movable sleeve are guided, and the threaded tube and the first bolt are threaded.

[0008] Furthermore, the support sleeve and the push block are in an inclined plane fit; the push block and the movable sleeve are in an inclined plane fit; and the movable sleeve and the threaded tube are in an inclined plane fit.

[0009] Furthermore, a first base, a second base, and a third base are sequentially provided at both ends of the main body, and the first base and the second base can be detachably connected to the main body; the second base and the third base are connected; the first base is configured to be able to install a support sleeve and limit the support sleeve to an extreme position moving away from the annular liquid sac, and to be able to install a push block and guide the sliding of the push block; the second base is configured to be able to install a movable sleeve; the second base and the third base are jointly configured to be able to install a threaded tube.

[0010] Furthermore, the quick splicing structure for door and window frames also includes two second bolts; the first base and the second base are connected to the main body through the second bolts.

[0011] Furthermore, the third substrate and the second substrate are connected by an adhesive.

[0012] Furthermore, when the pushing block moves in a direction away from the main body to an extreme position, the pushing block and the door and window frame are in frictional contact.

[0013] Furthermore, the door and window frames are fitted with a quick splicing structure and a clearance between the door and window frames.

[0014] Furthermore, the puncturing portion has a base ring and a plurality of puncture heads, and the base ring is sleeved on the annular liquid sac; the plurality of puncture heads are divided into two groups, and the two groups are respectively arranged at both ends of the base ring, and the puncture heads in the same group are arranged along the circumferential direction.

[0015] Furthermore, the base ring penetrates inwardly through one side wall of the annular liquid sac and extends to be fixed on the other inner side wall of the annular liquid sac.

[0016] Furthermore, an annular groove is provided at the corner of the body, the annular groove surrounds the corner of the body, and the annular liquid capsule is inserted into the annular groove.

[0017] The beneficial effects of the present invention are: During use, the quick-joining structure for door and window frames provided by the present invention rotates two first bolts, causing the threaded tube to approach the first bolts under threaded engagement, and driving the movable sleeve to move through a guiding engagement with the movable sleeve. The movable sleeve, when moving, drives the pushing block through a guiding engagement with the pushing block. The pushing block, when moving, drives the supporting sleeve toward the annular liquid sac through a guiding engagement with the supporting sleeve. The first annular conical surfaces of the two supporting sleeves push against the annular liquid sac, squeezing the two elastic sealing rings while expanding. When the two elastic sealing rings expand circumferentially until they contact the door and window frame, the space between the two elastic sealing rings is sealed. As the first annular conical surfaces of the two supporting sleeves continue to push against the annular liquid sac, the annular liquid sac is further squeezed and then punctured by the puncturing portion, allowing the colloid within the annular liquid sac to fill the space between the two elastic sealing rings. This simplifies operation while ensuring that the colloid can fill the main connection between the main body and the door and window frame, thereby improving the sealing performance of the door and window frame connection.

[0018] Furthermore, when the pushing block moves away from the main body to the limit position, the connection stability between the main body and the door and window frame is improved by setting the pushing block and the door and window frame to frictionally abut.

[0019] Furthermore, by setting up a quick splicing structure for door and window frames and a clearance fit with the door and window frames, the quick splicing structure for door and window frames can be easily inserted into the door and window frames during installation, thereby improving the installation efficiency while avoiding damage to the structure of the quick splicing structure for door and window frames and the door and window frames.

[0025] like Figures 1 to 8As shown, the quick splicing structure for door and window frames provided by the embodiment of the present invention is used to connect door and window frames, and is fixed to the door and window frames by a first bolt; the quick splicing structure for door and window frames is configured to include a main body 1, and the main body 1 is a right-angle structure; an annular liquid capsule 2 is sleeved at the corner of the main body 1, and the annular liquid capsule 2 is filled with a colloid, and a puncture portion 3 is provided on the annular liquid capsule 2, and the puncture portion 3 is configured to be able to puncture the annular liquid capsule 2, and elastic sealing rings 4 are provided at both ends of the annular liquid capsule 2; a support sleeve 5 is sleeved at both ends of the main body 1, and the support sleeve 5 can slide along the extension direction of the main body 1, and the end face of the support sleeve 5 facing the corner of the main body 1 is a first annular cone surface 501, and the small end of the first annular cone surface 501 faces the annular liquid capsule 2, so as to be able to slide in the support sleeve 5 When approaching the annular liquid sac 2, the annular liquid sac 2 can be squeezed through the first annular cone surface 501, and the elastic sealing ring 4 can be stretched and the space between the two elastic sealing rings 4 can be sealed; a plurality of pushing blocks 6 are arranged at intervals along the circumferential direction at both ends of the main body 1, and the pushing blocks 6 and the support sleeve 5 are guided to fit, and the pushing blocks 6 can slide in a direction perpendicular to the extension direction of the main body 1; a movable sleeve 7 and a threaded tube 8 are provided at both ends of the main body 1, and the movable sleeve 7 and the pushing blocks 6 are guided to fit, and the movable sleeve 7 can slide in the extension direction of the main body 1; the threaded tube 8 extends in a direction perpendicular to the extension direction of the main body 1 and can slide along its own axial direction, and the threaded tube 8 and the movable sleeve 7 are guided to fit, and the threaded tube 8 and the first bolt are threaded to fit.

[0026] Specifically in this embodiment, the main body 1 is a right-angled body, with one end extending to the right and the other end extending forward; the annular liquid sac 2 and the elastic sealing ring 4 can both be made of elastic materials, such as rubber, and the rubber has good elasticity to ensure that the annular liquid sac 2 and the elastic sealing ring 4 can be tightly fitted at the corners of the main body 1; in order to match the right-angle shape of the main body 1 and avoid interference, the side wall surface of the support sleeve 5 near the corner of the main body 1 is set as a slope and extends in the front right direction.

[0027] During use, first insert the right end of the main body 1 into the door and window frame, then move the main body 1 until the threaded tube 8 and the mounting screw hole on the door and window frame correspond, then align the first bolt with the mounting screw hole and the threaded tube 8 at the same time, and then rotate the first bolt so that the first bolt is gradually screwed into the threaded tube 8; when the first bolt and the door and window frame form a stop fit, the position of the main body 1 is fixed.

[0028] Then insert the front end of the body 1 into the door and window frame, close the door and window frame, and then repeat the above process of installing the first bolt.

[0029] Then, the two first bolts are rotated at the same time. Under the threaded cooperation, the threaded tube 8 approaches the first bolt and drives the movable sleeve 7 to move through the guiding cooperation between the movable sleeve 7. When the movable sleeve 7 moves, the pushing block 6 is driven to move through the guiding cooperation between the pushing block 6. When the pushing block 6 moves, the supporting sleeve 5 is driven to approach the annular liquid sac 2 through the guiding cooperation between the pushing block 6 and the supporting sleeve 5.

[0030] When the support sleeve 5 moves, the first annular cone surface 501 squeezes the annular liquid sac 2 while stretching the two elastic sealing rings 4; when the two elastic sealing rings 4 expand circumferentially to contact the door and window frames, the space between the two elastic sealing rings 4 is sealed, and as the first annular cone surfaces 501 of the two support sleeves 5 continue to push, the annular liquid sac 2 continues to be squeezed, and then the annular liquid sac 2 is punctured under the action of the puncturing portion 3. Since the annular liquid sac 2 is in a pressurized state before being punctured, the colloid therein is in a high-pressure state. When the annular liquid sac 2 is punctured, the colloid therein can be filled into the space between the two elastic sealing rings 4 from the rupture of the annular liquid sac 2 at a certain pressure, thereby effectively filling various tiny gaps that may exist between the two elastic sealing rings 4 and the door and window frames, and finally filling the space between the two elastic sealing rings 4. This glue injection method is not only extremely simple and quick to operate, but also can more effectively ensure the sealing effect compared to the traditional glue injection process. It avoids the situation of insufficient or excessive glue injection that may occur in the traditional glue injection process, ensures the uniform distribution of the glue in the sealed space, and thus comprehensively improves the sealing performance of the door and window frame joints.

[0031] To ensure simplicity of description, the following embodiments are described with reference to the components on the end of the body 1 extending forward. The structure, position and connection relationship of the components on the end of the body 1 extending rightward are the same and will not be repeated.

[0032] Furthermore, the support sleeve 5 and the pushing block 6 are in an inclined plane fit; the pushing block 6 and the movable sleeve 7 are in an inclined plane fit; and the movable sleeve 7 and the threaded tube 8 are in an inclined plane fit.

[0033] Specifically, in order to facilitate the guiding fit between the push block 6 and the support sleeve 5, a second annular conical surface 502 is formed at the junction of the front end face and the inner circumferential wall of the support sleeve 5, and the small end of the second annular conical surface 502 faces the corner of the main body 1; the rear side wall of the push block 6 is set as a slope, and the inclination direction of the slope and the second annular conical surface 502 are consistent to form a slope guiding fit.

[0034] In order to facilitate the guiding fit between the movable sleeve 7 and the pushing block 6, the rear end face of the movable sleeve 7 is a third annular conical surface 701, and the small end of the third annular conical surface 701 faces the corner of the main body 1; the front side wall of the pushing block 6 is a slope, and the slope and the third annular conical surface 701 have the same inclination direction to form a slope guiding fit.

[0035] In order to facilitate the guiding fit between the movable sleeve 7 and the threaded tube 8, a notch 702 is provided on the front end face of the movable sleeve 7, and a slope is formed in the notch 702, and the inclination direction of the slope intersects with the inclination direction of the third annular cone surface 701; a protrusion 801 is provided on the outer peripheral wall of the threaded tube 8, and the protrusion 801 extends along the radial direction of the threaded tube 8, and is inserted into the notch 702 during installation. A slope is provided at the junction of the rear side wall and the left side wall of the protrusion 801, and the slope extends in the left front direction and is consistent with the inclination direction of the slope on the movable sleeve 7 to form a slope guiding fit.

[0036] To more clearly describe the slope direction of the protrusion 801 and the notch 702, as shown in FIG. Figure 2 As shown, Figure 2 The left side is the rear, the right side is the front, the upper side is the right, and the lower side is the left. The inclined surface on the protrusion 801 and the inclined surface on the notch 702 both extend obliquely in the lower right direction.

[0037] Optionally, there may be two protrusions 801, spaced apart along the axis of the threaded tube 8. To match this, there may be two notches 702. During installation, the two protrusions 801 are respectively inserted into the two notches 702, and each forms a guiding engagement with the inclined surfaces within the notches 702. This improves the stability of the mating of the movable sleeve 7 and the threaded tube 8.

[0038] For example, there may be four push blocks 6 , which are evenly distributed along the circumference.

[0039] During use, turn the two first bolts, such as Figure 2 As shown, taking the support sleeve 5, the pushing block 6, the movable sleeve 7 and the threaded tube 8 at the lower position as an example, the threaded tube 8 moves downward under the threaded cooperation, and when the threaded tube 8 moves, the movable sleeve 7 is driven to move to the left through the inclined surface guide cooperation between the inclined surface on the protrusion 801 and the inclined surface in the notch 702; when the movable sleeve 7 moves, the pushing block 6 is driven to move outward through the guide cooperation between the third annular cone surface 701 and the right side wall of the pushing block 6; when the pushing block 6 moves, the support sleeve 5 is driven to move toward the corner of the body 1 through the inclined surface guide cooperation between the left side wall of the pushing block 6 and the second annular cone surface 502.

[0040] When the support sleeve 5 moves, the first annular conical surface 501 squeezes the annular liquid sac 2 while stretching the two elastic sealing rings 4; when the two elastic sealing rings 4 expand circumferentially to contact the door and window frame, the space between the two elastic sealing rings 4 is sealed. As the first annular conical surfaces 501 of the two support sleeves 5 continue to push, the annular liquid sac 2 continues to be squeezed, and then is punctured by the puncturing part 3, so that the colloid inside fills the space between the two elastic sealing rings 4.

[0041] In some embodiments, a first base 9, a second base 10, and a third base 11 are sequentially provided at both ends of the main body 1, and the first base 9 and the second base 10 can be detachably connected to the main body 1; the second base 10 and the third base 11 are connected; the first base 9 is configured to be able to install the support sleeve 5 and limit the support sleeve 5 to the extreme position of moving away from the annular liquid sac 2, and to be able to install the push block 6 and guide the sliding of the push block 6; the second base 10 is configured to be able to install the movable sleeve 7; the second base 10 and the third base 11 are jointly configured to be able to install the threaded tube 8.

[0042] Specifically in this embodiment, the support sleeve 5 is mounted on the body 1 and the first base 9 together during installation; in order to limit the support sleeve 5 from moving away from the annular liquid capsule 2, the limit position is as follows: Figure 3 As shown, a first step surface 901 is provided on the right side wall of the first base 9, and the first step surface 901 rises in the direction from back to front; a second step surface 503 is provided on the side wall surface of the support sleeve 5 on the inner side of the corner of the main body 1, and the direction of the second step surface 503 is the same as that of the first step surface 901 to form a stop fit, so that the support sleeve 5 has a limit distance to move in the direction away from the annular liquid sac 2, thereby having a limit position.

[0043] To facilitate the installation of the push block 6, as Figure 3 As shown, a number of first mounting holes 902 equal to the number of the pushing blocks 6 is provided on the side wall surface of the first base 9 away from the main body 1, and the plurality of first mounting holes 902 are arranged along the circumferential direction; the pushing blocks 6 are slidably inserted into the first mounting holes 902 during installation; in order to facilitate the sliding of the guiding pushing blocks 6, a number of sliding grooves 903 twice the number of the first mounting holes 902 is provided on the side wall surface of the first base 9 away from the main body 1, and two sliding grooves 903 form a group. Taking the first mounting hole 902 located on the left side wall of the first base 9 as an example, the two sliding grooves 903 are respectively provided on the upper and lower wall surfaces of the first mounting hole 902, and both extend along the extension direction of the main body 1; taking the pushing block 6 located at the lower part as an example, as shown Figure 7 As shown, slide bars 601 are provided near the top on the left and right side walls of the pushing block 6, and the slide bars 601 extend in the front-to-back direction; the two slide bars 601 on the same pushing block 6 are slidably inserted into the two slide grooves 903 on the same first mounting hole 902 during installation, and the pushing block 6 can move along the groove width direction of the slide groove 903 with the cooperation of the slide groove 903 and the slide bar 601, so that it can slide in a direction perpendicular to the extension direction of the main body 1.

[0044] For the convenience of installing the movable sleeve 7, as Figure 3As shown, the second base 10 is set to a T-shaped structure, and the large end is set toward the main body 1; the movable sleeve 7 is slidably sleeved on the small end of the second base 10 during installation; to facilitate the installation of the threaded tube 8, a first semi-circular arc hole 1001 is opened on the small end of the second base 10, and the first semi-circular arc hole 1001 extends in the left and right directions, and a second semi-circular arc hole 1101 is opened on the third base 11, and the second semi-circular arc hole 1101 extends in the left and right directions, and can form a complete circular hole structure together with the first semi-circular arc hole 1001; the threaded tube 8 is slidably inserted into the first semi-circular arc hole 1001 and the second semi-circular arc hole 1101 during installation.

[0045] In the process of assembling the quick splicing structure for door and window frames, the annular liquid bag 2 can be first sleeved on the corner of the main body 1, and then the support sleeve 5 can be sleeved on the end of the main body 1, and then the first base 9 can be inserted into the support sleeve 5 so that the first base 9 is located at the end of the main body 1, and then the pushing block 6 can be inserted into the first mounting hole 902 of the first base 9, and then the second base 10 can be inserted into multiple pushing blocks 6 so that the second base 10 is located at the end of the first base 9, and then the first base 9 and the second base 10 can be detachably connected to the main body 1, and then the threaded tube 8 can be inserted into the first semi-circular arc hole 1001, and then the third base 11 can be connected to the end of the second base 10, so that the first semi-circular arc hole 1001 and the second semi-circular arc hole 1101 together form a complete circular hole structure, and are sleeved on the threaded tube 8.

[0046] Furthermore, the quick-joining structure for the door and window frame is configured to further include two second bolts 12 ; the first base 9 and the second base 10 are connected to the body 1 together through the second bolts 12 .

[0047] Specifically, if Figure 3 As shown, a second mounting hole 102 is opened on the front side wall of the main body 1, and the second mounting hole 102 extends in the front-to-back direction, and the second mounting hole 102 can form a threaded fit with the second bolt 12; a third mounting hole 904 is opened through the front side wall of the first base 9, and the third mounting hole 904 extends in the front-to-back direction and can be connected with the second mounting hole 102; a fourth mounting hole 1002 is opened through the rear side wall of the second base 10, and the fourth mounting hole 1002 extends in the front-to-back direction, and is connected with the first semicircular arc hole 1001, and can be connected with the third mounting hole 904; the second bolt 12 can form a stop fit with the second base 10, so that the first base 9 and the second base 10 can be connected to the main body 1 together through the threaded fit between the second mounting hole 102.

[0048] During the process of assembling the quick splicing structure for door and window frames, when the second base 10 is located at the end of the first base 9, the second bolt 12 is passed through the fourth mounting hole 1002 and the third mounting hole 904 in sequence and then threadedly inserted into the second mounting hole 102; then the second bolt 12 is rotated, and the second bolt 12 is gradually screwed into the second mounting hole 102 through the threaded fit between it and the second mounting hole 102; when the second bolt 12 forms a stop fit with the second base 10, the first base 9 and the second base 10 are connected together to the main body 1.

[0049] Optionally, the third substrate 11 and the second substrate 10 may be configured to be detachably connected via an adhesive such as glue.

[0050] Optionally, the third base body 11 and the second base body 10 may also be configured to be detachably connected by bolts.

[0051] Optionally, the third base body 11 and the second base body 10 may also be configured to be fixedly connected by welding.

[0052] In other embodiments, when the pushing portion moves to the extreme position away from the main body 1, the pushing portion and the door / window frame come into frictional contact. This close frictional contact can significantly increase the friction between the main body 1 and the door / window frame. The increased friction effectively prevents relative displacement between the main body 1 and the door / window frame. This greatly enhances the stability of the connection between the main body 1 and the door / window frame, both under various external forces encountered in daily use and in special operating conditions such as strong winds and vibrations. This significantly increases the strength of the connection between the main body 1 and the door / window frame.

[0053] On the other hand, the friction between the pushing part and the door and window frame forms a mechanical interlocking effect. The surface structure of the pushing part fits with the contact part of the door and window frame, just like a mortise and tenon structure, which increases the complexity and stability of the connection at the microscopic level. This mechanical interlocking effect further strengthens the connection between the main body 1 and the door and window frame, so that the entire splicing structure can evenly disperse the force when it is subjected to external forces in various directions, avoiding the problem of connection failure caused by local stress concentration, and providing reliable guarantee for the long-term stable operation of the door and window frame.

[0054] In a further embodiment, in order to improve the convenience during installation, it is provided that the door and window frames are provided with a quick splicing structure and a clearance fit between the door and window frames.

[0055] Specifically in this embodiment, the circumferential dimensions of the main body 1 and the components arranged on its ends are smaller than the dimensions of the mounting holes on the door and window frames, so that the door and window frames can be easily inserted into the door and window frames using the quick-joining structure during installation. This improves the installation efficiency while avoiding the use of hammering, which would damage the quick-joining structure of the door and window frames and the structure of the door and window frames.

[0056] In other embodiments, the puncturing portion 3 is configured to have a base ring 301 and a plurality of puncture heads 302, and the base ring 301 is sleeved on the annular liquid sac 2; the plurality of puncture heads 302 are divided into two groups, and the two groups are respectively arranged at both ends of the base ring 301, and the puncture heads 302 in the same group are arranged along the circumferential direction.

[0057] Specifically in this embodiment, the base ring 301 is tightly fitted on the annular liquid sac 2, providing a stable support foundation for the thorn head 302; the thorn head 302 is configured as a strip structure and extends along the left front direction. Compared with other shapes, this strip structure can provide a larger puncture area and stronger puncture force when puncturing the annular liquid sac 2, ensuring the smooth progress of the puncture process.

[0058] During the squeezing process of the annular liquid sac 2, when the annular liquid sac 2 contacts the two groups of puncture heads 302, since the puncture heads 302 are distributed circumferentially at both ends of the base ring 301, they can puncture the annular liquid sac 2 at different positions at the same time, so that the annular liquid sac 2 can be punctured with multiple holes. The existence of multiple holes greatly increases the injection outlet of the colloid, so that the colloid can be quickly and evenly ejected from multiple positions. The quickly ejected colloid can fill the space between the two elastic sealing rings 4 in a short time, thereby improving the injection efficiency.

[0059] In a further embodiment, Figure 4 As shown, the base ring 301 extends inward through one sidewall of the annular sac 2 and extends to be fixed to the other inner sidewall of the annular sac 2. In this way, the base ring 301 can build a solid support framework inside the annular sac 2, which forms a tight and stable connection between the base ring 301 and the annular sac 2, greatly enhancing the reliability of the overall structure. When the annular sac 2 is squeezed by the external support sleeve 5, the base ring 301 can more effectively disperse the pressure, preventing the annular sac 2 from rupturing or deforming due to local uneven force, ensuring that the annular sac 2 can stably perform its glue storage and injection functions under various working conditions.

[0060] In addition, the way in which the base ring 301 penetrates deeply into the annular liquid capsule 2 makes the relative position of the piercing head 302 and the annular liquid capsule 2 more precise and stable; since the base ring 301 is tightly connected to the annular liquid capsule 2, when the annular liquid capsule 2 is pressurized and contacts the piercing head 302, the piercing head 302 can accurately pierce the annular liquid capsule 2 at a preset position, avoiding puncture position deviation or puncture failure caused by the position offset of the base ring 301; this ensures that the colloid can be ejected from a specific position as expected by the design, thereby achieving efficient filling of the sealed space.

[0061] In other embodiments, an annular groove 101 is provided at the corner of the body 1. The annular groove 101 surrounds the corner of the body 1, and the annular liquid capsule 2 is inserted into the annular groove 101. In this way, the annular groove 101 can provide precise positioning for the annular liquid capsule 2. Since the annular groove 101 closely surrounds the corner of the body 1, when the annular liquid capsule 2 is inserted therein, it can be accurately fixed in the desired position, ensuring that it maintains a precise relative position relationship with the surrounding support sleeve 5, spike head 302 and other components. This makes the coordinated work of various components more stable and reliable during the entire splicing and injection process, avoiding problems such as uneven injection or sealing failure caused by the position deviation of the annular liquid capsule 2.

[0062] In addition, the annular groove 101 can also play a good fixing role for the annular liquid sac 2. During the splicing process of door and window frames, it will be subjected to various external forces, and the existence of the annular groove 101 can effectively limit the movement of the annular liquid sac 2, so that it is firmly embedded in the corner of the main body 1. Even when subjected to large extrusion pressure or vibration, the annular liquid sac 2 can remain stably in place, ensuring the stability and reliability of the injection system.

[0063] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and modifications are possible without departing from the scope of the present invention, and such variations and modifications are fully within the scope of protection of the present invention.
