Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door and window fittings, in particular to a quick splicing structure for door and window frames. BACKGROUND

[0002] In the modern door and window manufacturing process, the connection quality of the door and window frame plays a crucial role in the overall performance of the door and window. As a kind of hardware used to connect 90-degree right-angle intersecting components, the corner code has been widely used in the connection of door and window frames.

[0003] At present, the installation process of the corner code mainly includes movable corner code process, corner striking process and pin injection process. Among them, the pin injection process is favored and widely used in the door and window manufacturing field due to its advantages of more firm corner assembly, better sealing and more beautiful appearance.

[0004] In related technologies, for example, Chinese patent CN210977150U discloses a door and window injection corner code. The door and window injection corner code includes a corner code body, the corner code body is provided with a first injection screw hole, a second injection screw hole, a flow channel and a flow distribution hole; during injection, the glue gun head is inserted into the first injection screw hole and starts to inject the glue. The glue first reaches the flow channel through the first injection screw hole, and then flows along the flow channel to the flow distribution hole. When the glue reaches the flow distribution hole, part of the glue is distributed through the flow distribution hole, and the other part of the glue continues to flow along the flow channel. Finally, the glue reaches saturation and flows out uniformly from the second injection screw hole, realizing glue sealing.

[0005] However, the above-mentioned door and window injection corner code also has some problems in the actual installation process. During the injection process, in order to ensure the injection quality, not only does the operator need to keep the glue gun head at the right angle, but also the operator needs to push the glue gun head with a certain force to ensure that the glue can be uniformly and stably injected into the connection between the corner code and the door and window frame, which undoubtedly increases the difficulty and complexity of the injection operation. In addition, the operator needs to pay attention to the flow and saturation of the glue during the injection process to avoid the situation of insufficient or excessive injection, which further increases the complexity of the operation and the requirement for the operator's attention.

[0035] As Figures 1 to 8As shown, the door and window frame quick splicing structure provided by the embodiment of the present application is used for connecting a door and window frame and is fixed on the door and window frame through a first bolt; the door and window frame quick splicing structure is provided as including a body 1, the body 1 is a right-angle structure; a corner of the body 1 is sleeved with a ring-shaped liquid bag 2, the ring-shaped liquid bag 2 is filled with a colloid, the ring-shaped liquid bag 2 is provided with a piercing part 3, the piercing part 3 is configured to be able to pierce the ring-shaped liquid bag 2, both ends of the ring-shaped liquid bag 2 are provided with elastic sealing rings 4; both ends of the body 1 are sleeved with support sleeves 5, the support sleeves 5 can slide along the extension direction of the body 1, one end face of the support sleeve 5 towards the corner of the body 1 is a first ring taper face 501, and the small end of the first ring taper face 501 faces the ring-shaped liquid bag 2, so that when the support sleeve 5 is close to the ring-shaped liquid bag 2, the ring-shaped liquid bag 2 can be squeezed by the first ring taper face 501, the elastic sealing rings 4 are pried open, and the space between the two elastic sealing rings 4 is sealed; both ends of the body 1 are circumferentially spaced apart and provided with a plurality of pushing blocks 6, the pushing blocks 6 and the support sleeves 5 are in guiding cooperation, and the pushing blocks 6 can slide in a direction perpendicular to the extension direction of the body 1; both ends of the body 1 are provided with moving sleeves 7 and threaded pipes 8, the moving sleeves 7 and the pushing blocks 6 are in guiding cooperation, and the moving sleeves 7 can slide along the extension direction of the body 1; the threaded pipes 8 extend in a direction perpendicular to the extension direction of the body 1 and can slide along the axial direction of the threaded pipes 8, the threaded pipes 8 and the moving sleeves 7 are in guiding cooperation, and the threaded pipes 8 and the first bolts are in threaded cooperation.

[0036] In this embodiment, the body 1 is a right-angle body, and one end extends to the right and the other end extends to the front; the ring-shaped liquid bag 2 and the elastic sealing ring 4 can be made of an elastic material such as rubber, which has good elasticity and ensures that the ring-shaped liquid bag 2 and the elastic sealing ring 4 can be closely sleeved at the corner of the body 1; to match the right-angle shape of the body 1 and avoid interference, the side wall surface of the support sleeve 5 close to the corner of the body 1 is provided as an inclined surface and extends in the front-right direction.

[0037] In use, first, the right end of the body 1 is inserted into the door and window frame, then the body 1 is moved to correspond the threaded pipe 8 and the mounting screw hole on the door and window frame, then the first bolt is aligned with the mounting screw hole and the threaded pipe 8 at the same time, then the first bolt is rotated to gradually screw into the threaded pipe 8; when the first bolt and the door and window frame form a stop cooperation, the position of the body 1 is fixed.

[0038] Then, the front end of the body 1 is inserted into the door and window frame, and the door and window frame is closed, and then the above process of installing the first bolt is repeated.

[0039] Then rotate the two first bolts at the same time, the threaded tube 8 is close to the first bolt under the thread cooperation, and drives the moving sleeve 7 to move through the guide cooperation between the moving sleeve 7 and the pushing block 6, the pushing block 6 moves through the guide cooperation between the pushing block 6 and the support sleeve 5 when the moving sleeve 7 moves, and the support sleeve 5 is close to the annular liquid bag 2 through the guide cooperation between the support sleeve 5 and the pushing block 6.

[0040] When the support sleeve 5 moves, the first annular taper surface 501 of the support sleeve 5 extrudes the annular liquid bag 2 and supports the two elastic sealing rings 4; when the two elastic sealing rings 4 expand along the circumference to contact the door and window frame, the space between the two elastic sealing rings 4 is sealed, and the annular liquid bag 2 continues to be extruded as the first annular taper surface 501 of the two support sleeves 5 continues to push, and then the annular liquid bag 2 is punctured under the action of the puncture part 3; since the annular liquid bag 2 is in a compressed state before being punctured, the colloid in the annular liquid bag 2 is in a high-pressure state, and when the annular liquid bag 2 is punctured, the colloid in the annular liquid bag 2 can be injected into the space between the two elastic sealing rings 4 at a certain pressure from the puncture of the annular liquid bag 2, so as to effectively fill various small gaps that may exist between the two elastic sealing rings 4 and the door and window frame, and finally fill the space between the two elastic sealing rings 4. This glue injection method is not only extremely simple and fast in operation, but also can more effectively ensure the sealing effect compared with the traditional glue injection process. It avoids the situation of insufficient or excessive glue injection in the traditional glue injection process, ensures the uniform distribution of the colloid in the sealing space, and thus improves the sealing performance of the door and window frame connection in all directions.

[0041] In order to ensure the simplicity of the description, the components on the end of the body 1 extending forward are described in the following embodiments, and the structure, position and connection relationship of the components on the end of the body 1 extending right are the same, which will not be described again.

[0042] Further, the support sleeve 5 and the pushing block 6 are inclined surface matched; the pushing block 6 and the moving sleeve 7 are inclined surface matched; the moving sleeve 7 and the threaded tube 8 are inclined surface matched.

[0043] Specifically, in order to facilitate the guide cooperation between the pushing block 6 and the support sleeve 5, the intersection of the front end face and the inner peripheral wall of the support sleeve 5 is formed with a second annular taper surface 502, and the small end of the second annular taper surface 502 faces the corner of the body 1; the rear side wall of the pushing block 6 is provided as an inclined surface, and the inclined surface and the second annular taper surface 502 are consistent in inclination direction to form inclined surface guide cooperation.

[0044] In order to facilitate the guide cooperation between the moving sleeve 7 and the pushing block 6, the rear end face of the moving sleeve 7 is a third annular taper surface 701, and the small end of the third annular taper surface 701 faces the corner of the body 1; the front side wall of the pushing block 6 is an inclined surface, and the inclined surface and the third annular taper surface 701 are consistent in inclination direction to form inclined surface guide cooperation.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] For example, there may be four push blocks 6 , which are evenly distributed along the circumference.

[0049] 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.

[0050] 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.

[0051] In some embodiments, the first base body 9 and the second base body 10 are detachably connected to the body 1, and the second base body 10 and the third base body 11 are connected; the first base body 9 is configured to be capable of mounting the support sleeve 5 and limiting the limit position of the support sleeve 5 moving away from the annular liquid bag 2, and is also capable of mounting the pushing block 6 and guiding the sliding of the pushing block 6; the second base body 10 is configured to be capable of mounting the moving sleeve 7; and the second base body 10 and the third base body 11 are collectively configured to be capable of mounting the threaded pipe 8.

[0052] Specifically in the embodiment, the support sleeve 5 is jointly sleeved on the body 1 and the first base body 9 when being mounted; in order to limit the limit position of the support sleeve 5 moving away from the annular liquid bag 2, as shown in Figure 3 , a first stepped surface 901 is arranged on the right side wall of the first base body 9, and the first stepped surface 901 rises in the direction from back to front; a second stepped surface 503 is arranged on the side wall surface inside the corner of the body 1, and the direction of the second stepped surface 503 is the same as that of the first stepped surface 901, so as to form a stop cooperation, so that the support sleeve 5 has a limit distance of moving away from the annular liquid bag 2, thereby having a limit position.

[0053] In order to facilitate the mounting of the pushing block 6, as shown in Figure 3 , a plurality of first mounting holes 902 equal in number to the pushing blocks 6 are arranged on the side wall surface of the first base body 9 away from the body 1, and the plurality of first mounting holes 902 are arranged in a circumferential direction; the pushing block 6 is slidingly inserted into the first mounting hole 902 when being mounted; in order to guide the sliding of the pushing block 6, a plurality of slide grooves 903 equal in number to twice the number of the first mounting holes 902 are arranged on the side wall surface of the first base body 9 away from the body 1, and two slide grooves 903 form a group, and the first mounting hole 902 located on the left side wall of the first base body 9 is taken as an example, the two slide grooves 903 are arranged on the upper and lower walls of the first mounting hole 902, respectively, and extend along the extension direction of the body 1.

In this way, through this close frictional abutment, on the one hand, the friction between the body 1 and the door and window frame can be significantly improved, and the increase of the friction effectively prevents the relative displacement between the body 1 and the door and window frame, whether under the action of various external forces in daily use or under special working conditions such as strong wind and vibration, the stability of the connection between the two can be greatly enhanced, and the connection strength between the body 1 and the door and window frame can be greatly improved.

[0063] On the other hand, the frictional abutment of the pushing part and the door and window frame forms a mechanical interlocking effect, the surface structure of the pushing part and the contact part of the door and window frame fit with each other, like a mortise and tenon structure, which increases the complexity and stability of the connection at the micro level, and this mechanical interlocking effect further strengthens the connection between the body 1 and the door and window frame, so that the entire splicing structure can evenly disperse the force when bearing 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.

[0064] In further embodiments, in order to improve the convenience during installation, the quick splicing structure for door and window frame is arranged to be gap-fitted with the door and window frame.

[0065] Specific to the present embodiment, the circumferential dimension of the body 1 and the components arranged on the end thereof is less than the dimension of the mounting hole on the door and window frame, so that the door and window frame can be easily inserted into the door and window frame with the quick splicing structure during installation, thereby improving the installation efficiency and avoiding the use of hammering method to cause damage to the structure of the door and window frame with the quick splicing structure and the door and window frame.

[0066] In other embodiments, the piercing part 3 is provided with a base ring 301 and a plurality of piercing heads 302, the base ring 301 is sleeved on the annular liquid bag 2, and the plurality of piercing heads 302 are divided into two groups, and the two groups are arranged at two ends of the base ring 301, respectively, and the piercing heads 302 in the same group are arranged in the circumferential direction.

[0067] Specific to the present embodiment, the base ring 301 is closely sleeved on the annular liquid bag 2 to provide a stable support base for the piercing heads 302; the piercing heads 302 are provided in a strip-shaped structure and extend in the left front direction. Compared with other shapes, this strip-shaped structure can provide a larger piercing area and a stronger piercing force when piercing the annular liquid bag 2, ensuring the smooth progress of the piercing process.

[0068] During the extrusion of the annular liquid bag 2, when the annular liquid bag 2 contacts the two groups of piercing heads 302, since the piercing heads 302 are distributed in the circumferential direction at both ends of the base ring 301, the piercing can be performed at different positions of the annular liquid bag 2 at the same time, so that the annular liquid bag 2 can be pierced with multiple holes. The existence of multiple holes greatly increases the ejection outlet of the colloid, so that the colloid can be quickly and uniformly ejected from multiple positions. The quickly ejected colloid can be filled between the two elastic sealing rings 4 in a short time, thereby improving the efficiency of the colloid injection.

[0069] In further embodiments, as shown in Figure 4 The base ring 301 penetrates one side wall of the annular liquid bag 2 inwardly and is extended and fixed on the other side inner wall of the annular liquid bag 2. In this way, the base ring 301 can build a firm support framework inside the annular liquid bag 2, which forms a close and stable connection between the base ring 301 and the annular liquid bag 2, greatly enhancing the reliability of the overall structure. When the annular liquid bag 2 is extruded by the external support sleeve 5, the base ring 301 can more effectively disperse the pressure, prevent the annular liquid bag 2 from being broken or deformed due to uneven local stress, and ensure that the annular liquid bag 2 can stably play its functions of storing and injecting glue under various working conditions.

[0070] In addition, the base ring 301 penetrates into the inside of the annular liquid bag 2, so that the relative position of the stab head 302 and the annular liquid bag 2 is more accurate and stable; since the base ring 301 is closely connected with the annular liquid bag 2, when the annular liquid bag 2 is pressed to contact the stab head 302, the stab head 302 can accurately pierce the annular liquid bag 2 at the preset position, avoiding the deviation of the piercing position or the failure of piercing due to the deviation of the position of the base ring 301; this ensures that the colloid can be ejected from the specific position as designed, realizing efficient filling of the sealed space.

[0071] In other embodiments, a ring groove 101 is arranged at the corner of the body 1, the ring groove 101 surrounds the corner of the body 1, and the annular liquid bag 2 is inserted into the ring groove 101. In this way, the ring groove 101 can provide accurate positioning for the annular liquid bag 2; since the ring groove 101 closely surrounds the corner of the body 1, when the annular liquid bag 2 is inserted, it can be accurately fixed at the required position, ensuring that it maintains an accurate relative positional relationship with the surrounding support sleeve 5, stab head 302 and other components, which makes the cooperation of the components more stable and reliable during the entire splicing and glue injection process, avoiding problems such as uneven glue injection or sealing failure due to the deviation of the position of the annular liquid bag 2.

[0072] In addition, the ring groove 101 can also play a good fixing role for the annular liquid bag 2; during the splicing of the door and window frame, various external forces will be applied, and the existence of the ring groove 101 can effectively limit the movement of the annular liquid bag 2, so that it is firmly embedded at the corner of the body 1; even when subjected to a large extrusion force or vibration, the annular liquid bag 2 can stably remain in place, ensuring the stability and reliability of the glue injection system.

[0073] The technical features of the above embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application.
