Description

Technical Field

[0001] This utility model relates to the field of door frame technology, specifically to a two-way snap-fit ​​metal door frame. Background Technology

[0002] The door frame is an important component of a door. In the past, it was generally made of wood. However, with the continuous depletion of wood resources and the increasing emphasis on environmental protection, especially in recent years with the accelerated pace of modern life, the demand for a high quality of life has been growing.

[0003] A search revealed that Chinese Patent (Publication No.: CN219733164U) discloses "a weld-free plug-in door frame including an upper frame, with side frames movably snapped onto one side surface of the upper frame, an upper metal piece fixedly installed on the upper surface of the upper frame by bolts, the upper frame being composed of upper and lower frames and left and right side frames, a protrusion fixedly installed at the front edge of the upper metal piece, a plug-in piece fixedly installed at one end edge of the upper frame, the plug-in pieces being evenly distributed at the upper and lower edges of the upper frame, a snap-fit ​​software fixedly installed at the top and middle of one side surface of the upper frame, the outer arc surface of the snap-fit ​​software being movably snapped onto the side frame, an outwardly protruding metal piece fixedly installed at the bottom front of the upper frame, the outwardly protruding metal piece being an integral structure with the upper metal piece, a tightening groove being formed on one side surface of the protrusion, a bidirectional pin plate fixedly installed on the inner bottom wall of the outwardly protruding metal piece, and a fixing through plate being connected to one side surface of the bidirectional pin plate."

[0004] However, in the process of implementing the relevant technologies, this type of technical solution has certain technical defects:

[0005] First, although the patent does not require welding, the door frame splicing process was time-consuming, especially when it was necessary to ensure the verticality and sealing between the frames. It often required repeated adjustments, resulting in low installation efficiency. Since the fixing method is irreversible, it is difficult to maintain or disassemble later. Once an installation error occurs or a part needs to be replaced, it often requires complete destructive dismantling, which increases costs and wastes resources.

[0006] Secondly, the doors and windows of this patent can only be inserted into the slot from a single direction (such as the indoor side or the outdoor side), which limits the installation flexibility. In scenarios that require bidirectional opening or a specific installation direction (such as fire doors or special building layouts), it cannot be adapted and the door frame structure needs to be customized or modified.

[0007] Third, the door frame of this type of patent is in a closed structure after installation. The snap-fit ​​groove area at the bottom of the door frame is prone to accumulating dust, rainwater residue or construction debris. However, due to the small space and lack of a dedicated cleaning channel, the impurities are difficult to remove completely. Long-term accumulation may corrode the metal surface or affect the sliding function of the door and window. The existing bottom partition structure of the door frame is mostly fixed and cannot be disassembled. When cleaning, it can only rely on external wiping or high-pressure washing, which cannot reach the internal dead corners, resulting in poor cleaning effect.

[0008] In view of this, the present invention proposes a two-way snap-fit ​​metal door frame. Utility Model Content

[0009] This invention proposes a two-way snap-fit ​​metal door frame, which solves the problem of cleaning difficulties caused by the inability to remove partitions in the prior art.

[0010] The technical solution of this utility model is as follows: A two-way snap-fit ​​metal door frame includes two pairs of horizontal and vertical frames. The two pairs of horizontal and vertical frames are spliced ​​together to form a rectangular structure. Both ends of the inner side of the horizontal frame are provided with snap-fit ​​grooves for sliding cooperation with doors and windows. The bottom of the inner side of each of the two snap-fit ​​grooves is fixedly connected to a mounting base. A partition is snapped into the inner side of each of the two mounting bases. Both ends of the mounting base are provided with positioning elements for preventing the partition from disengaging from the mounting base. Both ends of the horizontal frame are provided with connecting elements. The bottom of the vertical frame is provided with a mating groove for sliding cooperation with the connecting elements.

[0011] Preferably, the inner walls of both of the snap-fit ​​grooves are provided with drain outlets, and the lowest point of the drain outlets is flush with the top surface of the partition.

[0012] Preferably, the positioning element includes a positioning plate, and the top of the mounting base has a slot that slides with the positioning plate. A first spring is sleeved on the inner side of the slot, one end of the first spring abuts against the positioning plate, and the other end of the first spring abuts against the inner wall of the slot.

[0013] Preferably, the positioning plate has an L-shaped structure, and the horizontal section of the positioning plate abuts against the top surface of the partition.

[0014] Preferably, the connector includes a connecting sleeve fixedly connected to the end of the horizontal frame. The connecting sleeve is slidably engaged with the mating groove. One end of the connecting sleeve is slidably connected to a plurality of sliding rods penetrating the inner wall of the connecting sleeve. The plurality of sliding rods are distributed at equal angles around the connecting sleeve. One end of each of the plurality of sliding rods is fixedly connected to a wedge-shaped limiting block. The outer wall of the connecting sleeve is provided with a plurality of clearance grooves that slidably engage with the wedge-shaped limiting blocks. The other end of each of the plurality of sliding rods is fixedly connected to an arc-shaped pressure block. One end of the connecting sleeve is provided with a top pressing member that drives the plurality of sliding rods to slide synchronously by abutting against the arc-shaped pressure block.

[0015] Preferably, the connector further includes several second springs sleeved on the outside of the slide rod, one end of the second spring abutting against the arc-shaped pressure block, and the other end of the second spring abutting against the inner wall of the connecting sleeve.

[0016] Preferably, the pressing component includes a screw that penetrates the inner wall of the connecting sleeve. The screw is threadedly connected to the connecting sleeve. One end of the screw is fixedly connected to an abutment block, and the other end of the screw is fixedly connected to a nut.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. Through the connector design, the horizontal and vertical frames can be quickly slid together without repeatedly adjusting the verticality or sealing. During installation, simply slide the connecting sleeve into the mating groove and drive the wedge-shaped limiting block to fix it by operating the screw. When disassembling, simply rotate the screw in the opposite direction to release the restriction. This avoids the time-consuming problem of traditional welding or bolt fixing, greatly shortens the installation time, and supports non-destructive disassembly. No overall destruction is required when maintaining or replacing parts later, reducing resource waste and costs.

[0019] 2. Both ends of the horizontal frame are equipped with snap-fit ​​grooves, allowing doors and windows to be freely installed from the indoor or outdoor side (two-way snap-fit), which solves the limitation of existing technology that doors and windows can only be embedded in one direction.

[0020] 3. The partition is snapped onto the mounting base by positioning parts, and can be quickly removed for deep cleaning; this solves the problem of impurity accumulation caused by fixed partitions in traditional door frames, and the drain outlet is flush with the top surface of the partition to ensure smooth drainage of water and avoid corrosion or damage to the sliding function.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figures 1 to 6 As shown, this embodiment proposes a two-way snap-fit ​​metal door frame, including two pairs of horizontal frame 1 and vertical frame 2. The two pairs of horizontal frame 1 and vertical frame 2 are spliced ​​into a rectangular structure. Both ends of the inner side of the horizontal frame 1 are provided with snap-fit ​​grooves 11 that slide with the door or window. The inner walls of the two snap-fit ​​grooves 11 are provided with drain outlets 12. The lowest point of the drain outlets 12 is flush with the top surface of the partition 14. The bottom ends of the inner side of the two snap-fit ​​grooves 11 are fixedly connected to the mounting bases 13. The inner sides of the two mounting bases 13 are snap-fitted with the partition 14. Both ends of the mounting bases 13 are provided with positioning members 15 for preventing the partition 14 from disengaging from the mounting bases 13. Both ends of the horizontal frame 1 are provided with connectors 16. The bottom end of the vertical frame 2 is provided with a mating groove 21 that slides with the connectors 16.

[0031] Both ends of the horizontal frame 1 are provided with snap-fit ​​grooves 11, allowing the door and window to slide and engage with the snap-fit ​​grooves 11 from the inside or the outside. This enables multiple assembly methods and overcomes the limitation of existing doors and windows that can only be installed in one direction. During the installation of the horizontal frame 1 and the vertical frame 2, the horizontal frame 1 and the vertical frame 2 are quickly spliced ​​and fixed by the connector 16, which greatly shortens the installation time. Then, the partition 14 is directly snapped into the inside of the mounting base 13, and the positioning piece 15 is used to fix the partition 14 so that it cannot be detached from the mounting base 13. When it is necessary to clean the partition 14, the restriction on the partition 14 is released by operating the positioning piece 15, so that the partition 14 can be removed for cleaning. This solves the problem that it is difficult to clean the impurities or dust on the inside of the door frame in the existing technology.

[0032] Furthermore, the positioning component 15 includes a positioning plate 151. The top of the mounting base 13 is provided with a slot 152 that slides with the positioning plate 151. A first spring 153 is sleeved on the inner side of the slot 152. One end of the first spring 153 abuts against the positioning plate 151, and the other end of the first spring 153 abuts against the inner wall of the slot 152. The positioning plate 151 has an L-shaped structure, and the horizontal section of the positioning plate 151 abuts against the top surface of the partition 14.

[0033] The assembly and disassembly process of partition 14: During installation, first apply a pushing force to the positioning plate 151 at one end of the mounting base so that it is fully inserted into the slot 152. At this time, the first spring 153 is fully compressed and accumulates elastic potential energy under the pressure of the positioning plate 151. Then, one end of partition 14 is snapped into the inner side of the corresponding mounting base 13. Then, the positioning plate 151 is released so that the first spring 153 releases its potential energy. The first spring 153 drives the positioning plate 151 to move in the opposite direction and abut against the top surface of partition 14. Similarly, continue to apply a pushing force to the positioning plate 151 at the other end of the mounting base 13 so that it is fully inserted into the slot 152. Then, snap the other end of partition 14 into the inner side of the corresponding mounting base 13. After releasing the positioning plate 151, it abuts against the other end of partition 14 under the action of the first spring 153. This can completely prevent partition 14 from separating from mounting base 13, thereby fixing partition 14.

[0034] During disassembly, first apply a pushing force to the positioning plate 151 at one end of the mounting base so that it is fully inserted into the slot 152, causing the positioning plate 151 to detach from one end of the partition 14. Then, remove one end of the partition 14 from the inside of the mounting base 13. Next, apply a pushing force to the positioning plate 151 at one end of the mounting base so that it is fully inserted into the slot 152, causing the positioning plate 151 to detach from the other end of the partition 14. Then, remove the other end of the partition 14 from the inside of the mounting base 13. The entire structure enables quick assembly and disassembly of the partition 14, effectively shortening the assembly time of the partition 14 and thus improving installation efficiency. The detachable design of the partition 14 allows for easy removal of the partition 14 for deep cleaning, which can completely remove impurities or dust deposited at the bottom of the door frame, solving the problem that the cleaning of the inside of the door frame is limited by space in the prior art.

[0035] Furthermore, the connector 16 includes a connecting sleeve 161 fixedly connected to the end of the horizontal frame 1. The connecting sleeve 161 is slidably engaged with the mating groove 21. One end of the connecting sleeve 161 is slidably connected to a plurality of sliding rods 167 penetrating the inner wall of the connecting sleeve 161. The plurality of sliding rods 167 are distributed at equal angles around the connecting sleeve 161. One end of each of the sliding rods 167 is fixedly connected to a wedge-shaped limiting block 165. The outer wall of the connecting sleeve 161 is provided with a plurality of clearance grooves 166 that slidably engage with the wedge-shaped limiting blocks 165. The other end of each of the sliding rods 167 is fixedly connected to an arc-shaped pressure block 168. A second spring 169 is sleeved on the outer side of the slide rod 167. One end of the second spring 169 abuts against the arc-shaped pressure block 168, and the other end of the second spring 169 abuts against the inner wall of the connecting sleeve 161. One end of the connecting sleeve 161 is provided with a top pressing member that drives several slide rods 167 to slide synchronously by abutting against the arc-shaped pressure block 168. The top pressing member includes a screw 162 that penetrates the inner wall of the connecting sleeve 161. The screw 162 is threadedly connected to the connecting sleeve 161. One end of the screw 162 is fixedly connected to an abutment block 163, and the other end of the screw 162 is fixedly connected to a nut 164.

[0036] The splicing process of horizontal frame 1 and vertical frame 2: First, slide the connecting sleeve 161 at the end of horizontal frame 1 into the mating groove 21 of vertical frame 2. Then, adjust the angle of vertical frame 2 so that vertical frame 2 and horizontal frame 1 remain perpendicular and the connection is close together. Then, turn the nut 164 with a small wrench to make the screw 162 rotate. Then, the screw 162 drives the abutment block 163 to move closer to the arc surface pressure block 168. When the abutment block 163 and the arc surface pressure block 168 are fully in contact, all the arc surface pressure blocks 168 slide synchronously under the squeezing action of the abutment block 163. At this time, the second spring 169 is compressed and accumulates potential energy, so that all the sliding rods 167 drive the corresponding wedge-shaped limiting blocks 165 to extend out from the relief groove 166, so that the wedge-shaped limiting blocks 165 abut against the inner wall of vertical frame 2. At this time, under the restriction of the wedge-shaped limiting blocks 165, the connecting sleeve 161 cannot be separated from vertical frame 2, thereby realizing the installation of horizontal frame 1 and vertical frame 2.

[0037] Similarly, by rotating the nut 164 in the opposite direction and causing the screw 162 to rotate in the opposite direction, the abutment block 163 moves in the opposite direction and disengages from the arc-shaped pressure block 168. At this time, the second spring 169 releases potential energy, causing all the wedge-shaped limiting blocks 165 to slide completely into the relief groove 166. This releases the restriction on the connecting sleeve 161, allowing the connecting sleeve 161 to be directly separated from the vertical frame 2, thereby realizing the disassembly of the horizontal frame 1 and the vertical frame 2. The entire structure can realize the rapid splicing and fixing of the horizontal frame 1 and the vertical frame 2 without welding or a large number of bolts, effectively shortening the assembly time of the door frame and further improving the installation efficiency of the door frame.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
