Description

Technical Field

[0001] This invention relates to the field of door frame installation technology, and in particular to a connection structure for installing a complete door frame, and a connection method for the connection structure for installing a complete door frame. Background Technology

[0002] Door frame is an architectural and interior design term referring to the two door frames, one inside and one outside. Its main functions are to secure the door leaf, protect the corners of walls, and provide decoration.

[0003] Door frames are composed of multiple panels that are embedded into pre-drilled door openings during installation. Current technology uses nailing to secure door frames, employing a nail gun to fix them in place. This method requires numerous tools, is time-consuming and labor-intensive, and leaves nails exposed. Over time, these nails may loosen and protrude, affecting aesthetics and posing a risk of injury to pedestrians. Therefore, there is an urgent need for a nail-free door frame design that is easy to assemble. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a connection structure and method for installing prefabricated door frames. The specific technical solution is as follows:

[0005] A connecting structure for installing a prefabricated door frame includes a sleeve plate and a top plate. Two sleeve plates are provided. The top plate is detachably installed between adjacent top plates. A first baffle is provided on the back of each sleeve plate, and a second baffle is provided on the front. A connecting plate is fixedly installed on one side of each sleeve plate. The space enclosed between the connecting plate and the sleeve plate is a limiting cavity. A first positioning plate is fixedly connected to the first baffle and inserted into the limiting cavity. A positioning mechanism is detachably and elastically inserted into the door opening wall between the first positioning plate and the connecting plate. A second positioning plate is fixedly connected to the second baffle and slidably inserted into the limiting cavity. A locking mechanism is provided on the connecting plate and elastically inserted into the second positioning plate, with one end of the locking mechanism elastically inserted into the door opening wall.

[0006] As an improvement to the above technical solution, the doorway wall is provided with mounting holes for the ends of the positioning mechanism and the locking mechanism to be inserted. A positioning magnetic sleeve is fixedly installed in the mounting holes, and the ends of the positioning mechanism and the locking mechanism are magnetically inserted into the positioning magnetic sleeve.

[0007] As an improvement to the above technical solution, the positioning mechanism includes a threaded sleeve and a limiting component. The connecting plate has a threaded hole for threaded connection of the threaded sleeve to the outside. The limiting component is elastically and telescopically sleeved in the threaded sleeve. One end of the limiting component is inserted into the first baffle, and the other end passes through the threaded sleeve and is magnetically inserted into the positioning magnetic sleeve.

[0008] As an improvement to the above technical solution, the limiting component includes a first positioning magnetic rod, a first slider, and a first spring. The first slider is slidably inserted into a threaded sleeve. One end of the first slider is fixedly connected to the first spring, and the other end is fixedly connected to the first positioning magnetic rod. One end of the first positioning magnetic rod passes through the threaded sleeve and is inserted into the positioning magnetic sleeve. One end of the first spring is fixedly connected to an installation block, and the installation block is inserted into a first positioning insert plate.

[0009] As an improvement to the above technical solution, the locking mechanism includes a sleeve rod and a locking component. The connecting plate has a positioning hole for the sleeve rod to be installed. The locking component is elastically telescopically sleeved in the sleeve rod. One end of the locking component is inserted into the limiting cavity, and the other end passes through the sleeve rod and is magnetically inserted into the positioning magnetic sleeve.

[0010] As an improvement to the above technical solution, the locking component includes a second positioning magnetic rod, a second slider, a pressure block, and a second spring. The second slider is slidably inserted into the sleeve rod. One end of the second slider is fixedly connected to the pressure block, and the other end is fixedly connected to the second positioning magnetic rod. One end of the second positioning magnetic rod passes through the sleeve rod and is inserted into the positioning magnetic sleeve. The second spring is sleeved around the second positioning magnetic rod and is fixedly connected to the inner wall of the sleeve rod between the adjacent second slider.

[0011] As an improvement to the above technical solution, the pressure block near the second positioning plate has an arc-shaped structure. The second positioning plate has a squeezing groove for the pressure block to slide. The squeezing groove has an arc-shaped structure. The second positioning plate has a limiting groove for the pressure block to insert into. The limiting groove communicates with the squeezing groove.

[0012] As an improvement to the above technical solution, slide bars are fixedly connected to the bottom ends of both sides of the top plate, and a limiting groove for the slide bars to slide is provided at the top of the sleeve plate.

[0013] As an improvement to the above technical solution, a first decorative plate is slidably inserted between the top ends of the first baffles on adjacent sides, and a second decorative plate is slidably inserted between the top ends of the second baffles on adjacent sides.

[0014] A connection method for a connecting structure used in the installation of a prefabricated door frame includes the following steps:

[0015] S1: Reserved: Install positioning magnetic sleeves on the wall of the doorway at the positions corresponding to the first and second positioning magnetic rods;

[0016] S2: Opening: Holes are made in the sleeve plate, connecting plate, first positioning plate and second positioning plate;

[0017] S3: Assembly: Fix the connecting plate to one side of the sleeve plate, then insert the first positioning plate into the limiting cavity, then thread the threaded sleeve into the threaded hole, insert the mounting block into the hole of the first positioning plate, so that the first baffle is pressed against the wall outside the door opening, and then install the top plate between the top of the sleeve plate.

[0018] S4: Installation: Place the assembled kit at the doorway, push the first baffle, and the first and second positioning magnetic rods are magnetically positioned in the positioning magnetic sleeve. Then, insert the second positioning plate into the limiting cavity. As the second positioning plate goes deeper, the pressure block can slide in the extrusion groove. When the second baffle is pressed against the outside of the doorway wall, the pressure block is inserted into the limiting groove. Then, install the first and second decorative panels.

[0019] The beneficial effects of this invention are:

[0020] With the positioning and locking mechanisms in place, there is no need to nail the outside of the frame, preventing nails from being exposed. Installers also do not need to carry auxiliary tools to secure the frame, saving time and effort during installation and allowing for quick completion of the door frame installation. Furthermore, the nail-free process prevents nails from becoming loose and avoids nails protruding outside the door frame and scratching pedestrians, thus improving safety performance.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] Please refer to Figures 1-14 As shown, the present invention provides a connection structure for installing a complete door frame, including a sleeve plate 1 and a top plate 11. Two sleeve plates 1 are provided. The top plate 11 is detachably set between adjacent top plates 1. A first baffle 3 is provided on the back of the sleeve plate 1 and a second baffle 4 is provided on the front.

[0038] A connecting plate 2 is fixedly installed on one side of the sleeve plate 1. The space enclosed between the connecting plate 2 and the sleeve plate 1 is a limiting cavity. A first positioning plate 31 is fixedly connected to the first baffle 3 and inserted into the limiting cavity. A positioning mechanism that is elastically inserted into the wall of the door opening is detachably installed between the first positioning plate 31 and the connecting plate 2.

[0039] A second positioning plate 41 is fixedly connected to the second baffle 4 and is slidably inserted into the limiting cavity;

[0040] The connecting plate 2 is provided with a locking mechanism that is elastically inserted into the second positioning plate 41, and one end of the locking mechanism is elastically inserted into the wall of the door opening.

[0041] In this case, the combination of sleeve plate 1 and top plate 11 forms a door frame fitted inside the doorway. A connecting plate 2 is fixedly installed on one side of sleeve plate 1, with a gap cavity between the connecting plate 2 and sleeve plate 1. This gap cavity serves as a limiting cavity. During door frame installation, the connecting plate 2 is fixed to one side of sleeve plate 1, and then the first baffle 3 is aligned with the back of sleeve plate 1 and connecting plate 2, allowing the first positioning plate 31 to be inserted into the limiting cavity. The connecting plate 2 and the first positioning plate 31 are then fixed. At this point, a positioning mechanism is inserted into the connecting plate 2, allowing one end of the positioning mechanism to be inserted into the first positioning plate 31, while the other end protrudes outside the connecting plate 2. The top plate 11 is then installed between adjacent sleeve plates 1. By pushing the connecting plate 2 along the doorway, the doorway wall can compress the positioning mechanism, causing it to contract under elastic pressure. When the other end of the positioning mechanism is inserted into the doorway wall... After the pre-drilled hole is inserted, the other end of the positioning mechanism can be inserted into the pre-drilled hole to position the connecting plate 2. At this time, the first baffle 3 abuts against the wall outside the door opening. Then, the second positioning plate 41 is inserted into the limiting cavity, which enables the locking mechanism to slide and press against the second positioning plate 41 by fitting the sleeve plate 1 into the door opening. This allows the end of the positioning mechanism to be inserted into the wall inside the door opening to position and install the sleeve plate 1. Finally, the second baffle 4 can be mated to the outer side of the door opening wall to complete the installation of the door frame. There is no need to nail the outside of the sleeve plate 1, so the nails will not be exposed to the outside. There is also no need for the installer to carry auxiliary tools to fix the sleeve plate 1. The installation is time-saving and labor-saving, and the installation of the door frame can be completed quickly. At the same time, the nail-free process can prevent the nails from becoming loose and can avoid the nails protruding outside the door frame and scratching pedestrians, thus improving safety performance.

[0042] The wall of the doorway is provided with mounting holes for the ends of the positioning mechanism and the locking mechanism to be inserted. A positioning magnetic sleeve 7 is fixedly installed in the mounting holes, and the ends of the positioning mechanism and the locking mechanism are magnetically inserted into the positioning magnetic sleeve 7.

[0043] With the setting of positioning magnetic sleeve 7, when installing the door frame, first drill holes in the wall of the door opening, and then fix the positioning magnetic sleeve 7 in the drilled holes. The positioning magnetic sleeve 7 can be reserved in the designated position during the construction process to prevent drilling later.

[0044] After the door frame is inserted into the door opening, the ends of the positioning mechanism and the locking mechanism can be inserted into the positioning magnetic sleeve 7. The ends of the positioning mechanism and the locking mechanism are magnetically inserted into the positioning magnetic sleeve 7 to facilitate the magnetic fixation of the positioning mechanism and the locking mechanism, so as to ensure the overall fixation effect of the door frame and increase the stability of the installation.

[0045] The positioning mechanism includes a threaded sleeve 5 and a limiting component. The connecting plate 2 has a threaded hole 21 for threaded connection of the threaded sleeve 5. The limiting component is elastically and telescopically sleeved in the threaded sleeve 5. One end of the limiting component is inserted into the first baffle 3, and the other end passes through the threaded sleeve 5 and is magnetically inserted into the positioning magnetic sleeve 7.

[0046] The limiting components include a first positioning magnetic rod 51, a first slider 52, and a first spring 521. The first slider 52 is slidably inserted into the threaded sleeve 5. One end of the first slider 52 is fixedly connected to the first spring 521, and the other end is fixedly connected to the first positioning magnetic rod 51. One end of the first positioning magnetic rod 51 passes through the threaded sleeve 5 and is inserted into the positioning magnetic sleeve 7. One end of the first spring 521 is fixedly connected to a mounting block, which is inserted into the first positioning insert plate 31.

[0047] With the threaded sleeve 5 in place, the first slider 52 is inserted into the threaded sleeve 5. At this time, one end of the first positioning magnetic rod 51 passes through the threaded sleeve 5. During the process of fitting the sleeve 1 into the doorway, by pushing the sleeve 1, the wall of the doorway can squeeze the first positioning magnetic rod 51. At this time, the first spring 521 is in a compressed state. As the sleeve 1 slides, when the end of the first positioning magnetic rod 51 communicates with the positioning magnetic sleeve 7, the first spring 521 releases its elastic force, so that the end of the first positioning magnetic rod 51 is inserted into the positioning magnetic sleeve 7. At this time, the first positioning magnetic rod 51 is magnetically attracted into the positioning magnetic sleeve 7, thereby positioning the connecting plate 2 and the sleeve 1 and preventing the connecting plate 2 and the sleeve 1 from sliding. At this time, the first baffle 3 is pressed against the outer wall of the doorway, completing the pre-installation of the door frame.

[0048] The locking mechanism includes a sleeve rod 6 and a locking component. The connecting plate 2 has a positioning hole 22 for the sleeve rod 6 to be installed. The locking component is elastically telescopically sleeved in the sleeve rod 6. One end of the locking component is inserted into the limiting cavity, and the other end passes through the sleeve rod 6 and is magnetically inserted into the positioning magnetic sleeve 7.

[0049] The locking component includes a second positioning magnetic rod 61, a second slider 62, a pressure block 621, and a second spring 63. The second slider 62 is slidably inserted into the sleeve 6. One end of the second slider 62 is fixedly connected to the pressure block 621, and the other end is fixedly connected to the second positioning magnetic rod 61. One end of the second positioning magnetic rod 61 passes through the sleeve 6 and is inserted into the positioning magnetic sleeve 7. The second spring 63 is sleeved around the second positioning magnetic rod 61 and is fixedly connected to the inner wall of the sleeve 6 and the adjacent second slider 62.

[0050] By setting the sleeve rod 6, during the process of fitting the sleeve plate 1 into the doorway, pushing the sleeve plate 1 can cause the doorway wall to squeeze the second positioning magnetic rod 61. At this time, the second spring 63 is in a compressed state. As the sleeve plate 1 slides, when the end of the second positioning magnetic rod 61 communicates with the positioning magnetic sleeve 7, the second spring 63 releases its elastic force, so that the end of the second positioning magnetic rod 61 is inserted into the positioning magnetic sleeve 7. At this time, the second positioning magnetic rod 61 is magnetically attracted in the positioning magnetic sleeve 7, thereby positioning the connecting plate 2 and the sleeve plate 1.

[0051] The pressure block 621 has an arc-shaped structure near the second positioning plate 41. The second positioning plate 41 has a pressing groove 411 for the pressure block 621 to slide. The pressing groove 411 has an arc-shaped structure. The second positioning plate 41 has a limiting groove 412 for the pressure block 621 to insert into. The limiting groove 412 communicates with the pressing groove 411.

[0052] After inserting the sleeve plate 1 into the door opening, the second positioning plate 41 is inserted into the limiting cavity, allowing the pressure block 621 to slide within the pressing groove 411. As the second positioning plate 41 slides, it presses the pressure block 621. During the sliding process, it presses the second spring 63 and allows the second positioning magnetic rod 61 to penetrate into the positioning magnetic sleeve 7. Simultaneously, when the pressure block 621 communicates with the limiting groove 412, the second spring 63 releases its elastic force, allowing the pressure block 621 to be inserted into the limiting groove 412. This allows both the second positioning magnetic rod 61 to be inserted into the positioning magnetic sleeve 7 and the pressure block 621 to be inserted into the limiting groove 412 to position the second positioning plate 41, ensuring the installation stability of the second baffle 4. At this time, the second baffle 4 is pressed against the outer wall of the door opening, thus completing the installation of the door frame.

[0053] During installation, adhesive can be applied to the first baffle 3 and the second baffle 4 near the wall to increase the stability of the installation.

[0054] Slide bars 111 are fixedly connected to the bottom of both sides of the top plate 11, and a limiting groove 13 for sliding the slide bars 111 is opened at the top of the sleeve plate 1.

[0055] A first decorative plate is slidably inserted between the top ends of the first baffle 3 on adjacent sides, and a second decorative plate is slidably inserted between the top ends of the second baffle 4 on adjacent sides.

[0056] The sliding strip 111 facilitates the installation of the top plate 11 and allows for the limiting of the top plate 11. At the same time, the first and second decorative plates protect the wall edges. A connecting strip 12 is fixedly connected between the connecting plate 2 and the sleeve plate 1.

[0057] A connection method for a connecting structure used in the installation of a prefabricated door frame includes the following steps:

[0058] S1: Reserved: Install positioning magnetic sleeves 7 on the wall of the doorway at the positions corresponding to the first positioning magnetic rod 51 and the second positioning magnetic rod 61;

[0059] S2: Opening: Holes are made in the sleeve plate 1, connecting plate 2, first positioning insert plate 31 and second positioning insert plate 41;

[0060] S3: Assembly: Fix the connecting plate 2 to one side of the sleeve plate 1, then insert the first positioning plate 31 into the limiting cavity, then thread the threaded sleeve 5 into the threaded hole 21, insert the mounting block into the hole of the first positioning plate 31, so that the first baffle 3 is pressed and adhered to the wall outside the door opening, and then install the top plate 11 between the top of the sleeve plate 1.

[0061] S4: Installation: Place the assembled kit at the doorway, push the first baffle 3, and the first positioning magnetic rod 51 and the second positioning magnetic rod 61 are magnetically positioned in the positioning magnetic sleeve 7. Then, insert the second positioning insert 41 into the limiting cavity. As the second positioning insert 41 goes deeper, the pressure block 621 can slide in the extrusion groove 411. When the second baffle 4 is pressed against the outside of the doorway wall, the pressure block 621 is inserted into the limiting groove 412. Then, install the first decorative panel and the second decorative panel.

[0062] After the first and second decorative panels are installed, the edges of the first baffle 3 and the second baffle 4 can be glued to the wall. After the first positioning plate 31 is inserted into the limiting cavity, the positioning nut can be threaded onto the connecting plate 2 and the first positioning plate 31 to increase the stability of the installation.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
